Sample records for renal transplant donor

  1. Renal Transplantation from Elderly Living Donors

    Jacob A. Akoh


    Full Text Available Acceptance of elderly living kidney donors remains controversial due to the higher incidence of comorbidity and greater risk of postoperative complications. This is a review of publications in the English language between 2000 and 2013 about renal transplantation from elderly living donors to determine trends and effects of donation, and the outcomes of such transplantation. The last decade witnessed a 50% increase in living kidney donor transplants, with a disproportionate increase in donors >60 years. There is no accelerated loss of kidney function following donation, and the incidence of established renal failure (ERF and hypertension among donors is similar to that of the general population. The overall incidence of ERF in living donors is about 0.134 per 1000 years. Elderly donors require rigorous assessment and should have a predicted glomerular filtration rate of at least 37.5 mL/min/1.73 m2 at the age of 80. Though elderly donors had lower glomerular filtration rate before donation, proportionate decline after donation was similar in both young and elderly groups. The risks of delayed graft function, acute rejection, and graft failure in transplants from living donors >65 years are significantly higher than transplants from younger donors. A multicentred, long-term, and prospective database addressing the outcomes of kidneys from elderly living donors is recommended.

  2. Donor Transmission of Melanoma Following Renal Transplant

    Kathryn T. Chen


    Full Text Available Donor transmission of melanoma is one of the more common and lethal of recipient malignancies, often presenting with systemic disease. Although some patients may receive durable remission of melanoma following explantation of the allograft and withdrawal of immunosuppression, donor transmission of melanoma is fatal in most patients. Here we present a case of a 44-year-old male who developed metastatic melanoma following renal transplant.

  4. Renal transplantation between HIV-positive donors and recipients justified.

    Muller, Elmi; Barday, Zunaid; Mendelson, Marc; Kahn, Delawir


    HIV infection was previously an absolute contraindication to renal transplantation. However, with the advent of highly active antiretroviral therapy (HAART), renal transplantation using HIV-negative donor kidneys has successfully been employed for HIV-infected patients with end-stage renal failure. In resource-limited countries, places on dialysis programmes are severely restricted; HIV-infected patients, like many others with co-morbidity, are often denied treatment. Kidneys (and other organs) from HIV-infected deceased donors are discarded. The transplantation of HIV-positive donor kidneys to HIV-infected recipients is now a viable alternative to chronic dialysis or transplantation of HIV-negative donor kidneys. This significantly increases the pool of donor kidneys to the advantage of HIV-positive and -negative patients. Arguments are presented that led to our initiation of renal transplantation from HIV-positive deceased donors to HIV-positive recipients at Groote Schuur Hospital, Cape Town.

  6. Living donor renal transplantation in patients with antiphospholipid syndrome

    Choi, Ji Yoon; Jung, Joo Hee; Shin, Sung; Kim, Young Hoon; Han, Duck Jong


    Abstract Introduction: Antiphospholipid syndrome (APS), autoantibodies directed against phospholipid-binding proteins are associated with cause vascular thrombosis. Patients with APS requiring renal transplantation are at risk of early graft loss due to arterial or venous thrombosis, or thrombotic microangiopathy (TMA). Here, we report 3 cases of successful renal transplantation in patients with APS. Clinical Findings: A 53-year-old man with end-stage renal disease (ESRD) had experienced bilateral deep venous thrombosis (DVT) in the lower extremities 16 years ago and was administered warfarin. However, he frequently experienced recurrent DVT despite of anticoagulation therapy. Before the surgery, APS was confirmed based on positive results lupus anticoagulant in serological tests. A 40-year-old man with polycystic kidney disease and a history recurrent DVT tested positive for lupus anticoagulant and anticardiolipin antibodies. Lastly, a 42-year-old woman with ESRD was diagnosed with APS 7 years ago. She also developed DVT and tested positive for lupus anticoagulant and anti-B2-glycoprotein 1. The anticoagulation protocol was as follows in all cases: Warfarin was stopped 5 days before living donor renal transplantation and intravenous heparin therapy was started. During surgery, bolus heparin injections (3000 U) were administered to prevent arterial or venous thrombosis. Heparin was substituted with warfarin on postoperative day 4. The third patient (42/F) developed clinical rejection indicated by increased serum creatinine levels and donor-specific antibodies (DSA) and received steroid pulse therapy, plasmapheresis, and rituximab. This treatment restored graft function to within the normal range. The latest graft function in all patients was maintained at normal levels in the outpatient clinic. Conclusions: Living donor renal transplantation may be successful in patients with APS following perioperative anticoagulation therapy. However, because of the high risk of

    Gopalakrishnan, N.; Dineshkumar, T.; Dhanapriya, J.; Sakthirajan, R.; Balasubramaniyan, T.; Srinivasa Prasad, N. D.; Thirumalvalavan, K.; Murugananth, S.; Kawaskar, K.


    Deceased donor renal transplantation (DDRT) constitutes less than 5% of all kidney transplantats in India. A retrospective analysis of 173 deceased donor renal transplants performed in a public funded government hospital was done. Mean age of the recipients was 36 years (male:female ratio 2.4:1), and that of the donors was 32.3 years (male:female ratio 6:1). The cold ischemic time was 340 ± 170 minutes. Mean follow-up period was 36 months. Forty one patients died, 75% of them in the first post – transplant year. Sepsis and cardiovascular disease were the most common causes of death. Twenty two percent had acute rejection. There was no significant difference in the incidence in the rate of acute rejection, bacterial, fungal infections and death rate between the cohorts of induction and non induction immunosuppression. The patient and death censored graft survival at 1 year were 80 and 82.6% and at 5 years were 76 and 80% respectively. PMID:28182043

  9. Identification of donor melanoma in a renal transplant recipient.

    Wilson, L J; Horvat, R T; Tilzer, L; Meis, A M; Montag, L; Huntrakoon, M


    A patient with chronic renal failure received a closely matched cadaveric kidney. Approximately 3 months after transplantation, the patient developed a metastatic malignant melanoma. A large retroperitoneal mass consisting of large pleomorphic polygonal neoplastic cells was found close to the donated kidney. This tumor was diagnosed as a malignant melanoma. DNA analysis of this tumor, the donated kidney, and the recipient indicated that the melanoma originated from the donor. Although this is not the first report of a donated melanoma, it is the first report of definitive DNA analysis of the origin of the malignant cells.

  10. Donor-Recipient Size Mismatch in Paediatric Renal Transplantation

    J. Donati-Bourne


    Full Text Available Introduction. End stage renal failure in children is a rare but devastating condition, and kidney transplantation remains the only permanent treatment option. The aim of this review was to elucidate the broad surgical issues surrounding the mismatch in size of adult kidney donors to their paediatric recipients. Methods. A comprehensive literature search was undertaken on PubMed, MEDLINE, and Google Scholar for all relevant scientific articles published to date in English language. Manual search of the bibliographies was also performed to supplement the original search. Results. Size-matching kidneys for transplantation into children is not feasible due to limited organ availability from paediatric donors, resulting in prolonged waiting list times. Transplanting a comparatively large adult kidney into a child may lead to potential challenges related to the surgical incision and approach, vessel anastomoses, wound closure, postoperative cardiovascular stability, and age-correlated maturation of the graft. Conclusion. The transplantation of an adult kidney into a size mismatched paediatric recipient significantly reduces waiting times for surgery; however, it presents further challenges in terms of both the surgical procedure and the post-operative management of the patient’s physiological parameters.

  11. Targeting complement activation in brain-dead donors improves renal function after transplantation.

    Kidneys recovered from brain-dead donors have inferior outcomes after transplantation compared to kidneys from living donors. Since complement activation plays an important role in renal transplant related injury, targeting complement activation in brain-dead donors might improve renal function after transplantation. Brain death (BD) was induced in Fisher rats by inflation of an epidurally placed balloon catheter and ventilated for 6h. BD animals were treated with soluble complement receptor 1 (sCR1) 1h before or 1h after BD. Kidney transplantation was performed and 7 days after transplantation animals were sacrificed. Plasma creatinine and urea were measured at days 0, 1, 3, 5 and 7 after transplantation. Renal function was significantly better at day 1 after transplantation in recipients receiving a sCR1 pre-treated donor kidney compared to recipients of a non-treated donor graft. Also treatment with sCR1, 1h after the diagnosis of BD, resulted in a better renal function after transplantation. Gene expression of IL-6, IL-1beta and TGF-beta were significantly lower in renal allografts recovered from treated donors. This study shows that targeting complement activation, during BD in the donor, leads to an improved renal function after transplantation in the recipient.

  12. Ethical aspects of renal transplantation from living donors.

    Bruzzone, P; Berloco, P B


    Kidney transplantation from living donors is widely performed all over the world. Living nephrectomy for transplantation has no direct advantages for the donor other than increased self-esteem, but it at least remains an extremely safe procedure, with a worldwide overall mortality of 0.03%. This theoretical risk for the donor seems to be justified by the socioeconomic advantages and increased quality of life of the recipient, especially in selected cases, such as pediatric patients, when living donor kidney transplantation can be performed in a preuremic phase, avoiding the psychological and physical stress of dialysis, which in children is not well tolerated and cannot prevent retarded growth. According to the Ethical Council of the Transplantation Society, commercialism must be effectively prevented, not only for ethical but also medical reasons. The risks are too high, not only for the donors, but also for the recipients, as a consequence of poor donor screening and evaluation with consequent transmission of human immunodeficiency virus (HIV) or other infective agents, as well as of inappropriate medical and surgical management of donors and also recipients, who are often discharged too early. Most public or private insurance companies consider kidney donation a safe procedure without long-term impairment and therefore do not increase the premium, whereas recipient insurance of course should cover hospital fees for the donors. "Rewarded gifting" or other financial incentives to compensate for the inconvenience and loss of income related to the donation are not advisable, at least in our opinion. Our Center does not perform anonymous living organ donation or "cross-over" transplantation.

  13. The impact of donor myelofibrosis on outcome of renal transplantation

    Tahawar Rana


    Full Text Available In donors known to have medical conditions associated with kidney damage, caution is exercised when accepting donor kidneys. Myelofibrosis can affect kidney function in a variety of ways, but is not generally considered a contraindication to donation. We present the case of a 27-year-old woman with known myelofibrosis who died from an upper gastrointestinal bleed. After cardiac death, both the kidneys were donated. The first recipient was a 34-year-old lady with focal segmental glomerular sclerosis in her single pelvic kidney. There was delayed graft function and the kidney continued to function poorly due to a significant donor vascular disease. The second recipient was a 27-year-old man with posterior urethral valves. Similar donor vascular disease caused this transplant to fail. The kidney damage did not fit any pattern reported in myelofibrosis, but may represent part of a spectrum of damage seen with this disease. This case highlights the need for caution when accepting kidneys from donors with chronic medical conditions even when young, and may be of use to transplant teams when considering accepting future donations from patients with myelofibrosis.

  14. A histopathological score on baseline biopsies from elderly donors predicts outcome 1 year after renal transplantation

    Toft, Birgitte G; Federspiel, Birgitte H; Sørensen, Søren S


    Kidneys from elderly deceased patients and otherwise marginal donors may be considered for transplantation and a pretransplantation histopathological score for prediction of postoperative outcome is warranted. In a retrospective design, 29 baseline renal needle biopsies from elderly deceased donors...... wall thickness of arteries and/or arterioles. Nineteen renal baseline biopsies from 15 donors (age: 64 ± 10 years) were included and following consensus the histopathological score was 4.3 ± 2.1 (intraclass correlation coefficient: 0.81; confidence interval: 0.66-0.92). The donor organs were used...... for single renal transplantation (recipient age: 47 ± 3 years). Two grafts were lost after the transplantation. In the remaining 17 recipients the 1-year creatinine clearance (54 ± 6 mL/min) correlated to the baseline histopathological score (r(2) = 0.59; p

  15. MDCT evaluation of potential living renal donor, prior to laparoscopic donor nephrectomy: What the transplant surgeon wants to know?

    Nitin P Ghonge


    Full Text Available As Laparoscopic Donor Nephrectomy (LDN offers several advantages for the donor such as lesser post-operative pain, fewer cosmetic concerns and faster recovery time, there is growing global trend towards LDN as compared to open nephrectomy. Comprehensive pre-LDN donor evaluation includes assessment of renal morphology including pelvi-calyceal and vascular system. Apart from donor selection, evaluation of the regional anatomy allows precise surgical planning. Due to limited visualization during laparoscopic renal harvesting, detailed pre-transplant evaluation of regional anatomy, including the renal venous anatomy is of utmost importance. MDCT is the modality of choice for pre-LDN evaluation of potential renal donors. Apart from appropriate scan protocol and post-processing methods, detailed understanding of surgical techniques is essential for the Radiologist for accurate image interpretation during pre-LDN MDCT evaluation of potential renal donors. This review article describes MDCT evaluation of potential living renal donor, prior to LDN with emphasis on scan protocol, post-processing methods and image interpretation. The article laid special emphasis on surgical perspectives of pre-LDN MDCT evaluation and addresses important points which transplant surgeons want to know.

  16. Major influence of renal function on hyperlipidemia after living donor liver transplantation

    Ling, Qi; Wang, Kai; Lu, Di; Guo, Hai-Jun; Jiang, Wen-Shi; He, Xiang-Xiang; Xu, Xiao; Zheng, Shu-Sen


    AIM: To investigate the impact of renal and graft function on post-transplant hyperlipidemia (PTHL) in living donor liver transplantation (LDLT). METHODS: A total of 115 adult patients undergoing LDLT from January 2007 to May 2009 at a single center were enrolled. Data were collected and analyzed by the China Liver Transplant Registry retrospectively. PTHL was defined as serum triglycerides ≥ 150 mg/dL or serum cholesterol ≥ 200 mg/dL or the need for pharmacologic treatment at the sixth month after LDLT. Early renal dysfunction (ERD) was defined as serum creatinine ≥ 2 mg/dL and/or the need for renal replacement therapy in the first post-transplant week. RESULTS: In 115 eligible patients, the incidence of PTHL was 24.3%. Recipients with PTHL showed a higher incidence of post-transplant cardiovascular events compared to those without PTHL (17.9% vs 4.6%, P = 0.037). Serum creatinine showed significant positive correlations with total serum triglycerides, both at post-transplant month 1 and 3 (P transplant serum creatinine levels (P transplant renal insufficiency (P transplant serum creatinine, graft-to-recipient weight ratio, graft volume/standard liver volume ratio, body mass index (BMI) and ERD were identified as risk factors for PTHL by univariate analysis. Furthermore, ERD [odds ratio (OR) = 9.593, P transplant renal dysfunction, which mainly results from pre-transplant renal insufficiency, contributes to PTHL. PMID:23323005

  17. Ureteric complications in live related donor renal transplantation - impact on graft and patient survival

    A Srivastava


    Full Text Available Objective : The study was performed with an aim to determine the incidence of ureteric complications in live related donor renal transplantation, and to study the effect of ureteric complications on long term graft and patient survival. Patients And Methods: Records of 1200 consecutive live related renal transplants done from 1989-2002 were reviewed. Twenty-six ureteric complications were noted to occur and treatment modalities employed were documented. In the non complication group sufficient data for evaluation was available in 867 patients. Survival analysis were performed using Kaplan-Meier techniques. Results: The overall incidence of urological complications is 2.9%. Complications occurred at a mean interval of 31.9 days after renal transplantation. Ureteric complications occurred in 2% patients with stented and 7.7% patients with non stented anastomosis (p=0.001. Mean follow up following renal transplantation was 37.4 months. Survival analysis showed that ureteric complications did not increase the risk of graft fai lu re or patient death. Conclusions: Ureteric complications in live related donor renal transplantation occurred in 2.9 % patients and did not impair graft and patient survival.

  19. 'It's a regional thing': financial impact of renal transplantation on live donors.

    McGrath, Pam; Holewa, Hamish


    There has been no research exploring the financial impact on the live renal donor in terms of testing, hospitalisation and surgery for kidney removal (known as nephrectomy). The only mention of financial issues in relation to live renal transplantation is the recipients' concerns in relation to monetary payment for the gift of a kidney and the recipients' desire to pay for the costs associated with the nephrectomy. The discussion in this article posits a new direction in live renal donor research; that of understanding the financial impact of live renal donation on the donor to inform health policy and supportive care service delivery. The findings have specific relevance for live renal donors living in rural and remote locations of Australia. The findings are presented from the first interview (time 1: T1) of a set of four times (time 1 to time 4: T1-T4) from a longitudinal study that explored the experience of live renal donors who were undergoing kidney removal (nephrectomy) at the Renal Transplantation Unit at the Princess Alexandra Hospital, Brisbane, Australia. A qualitative methodological approach was used that involved semi-structured interviews with prospective living kidney donors (n=20). The resulting data were analysed using the qualitative research methods of coding and thematic analysis. The findings indicate that live renal donors in non-metropolitan areas report significant financial concerns in relation to testing, hospitalisation and surgery for nephrectomy. These include the fact that bulk billing (no cost to the patient for practitioner's service) is not always available, that individuals have to pay up-front and that free testing at local public hospitals is not available in some areas. In addition, non-metropolitan donors have to fund the extra cost of travel and accommodation when relocating for the nephrectomy to the specialist metropolitan hospital. Live renal transplantation is an important new direction in medical care that has excellent

  20. Renal Transplantation Using Stone-bearing Deceased Donor Kidneys-Experience of a Transplant Center in China.

    Chen, Chuan-Bao; Zhao, Liang; Han, Ming; Wang, Xiao-Ping; Zhou, Jian; Yuan, Xiao-Peng; Wang, Chang-Xi


    To evaluate the outcomes of transplantation of deceased donor stone-bearing kidneys. A total of 32 patients who received renal transplantation at our center from July 2011 to June 2016 were included. Eight recipients received kidneys with incidental renal stone(s) (stone group). Twenty-four recipients received kidneys without renal stones (non-stone group). The transplantation outcomes of the 2 groups were compared. There was 1 case of postoperative urinary tract infection in the stone group, and 2 cases in the non-stone group. No ureteral obstruction or hydronephrosis occurred in either group. No significant difference was found in the incidence of complications, serum creatinine level, and estimated glomerular filtration rate between the groups (all, P >.05). No deaths occurred in either group during the follow-up period. One recipient had postoperative calculi recurrence, and 4 recipients had residual calculi before transplantation. However, these patients had no symptomatic nephrolithiasis or obstruction, and their renal functions were normal. Transplantation of deceased donor stone-bearing kidneys can achieve comparable outcomes of deceased donor non-stone-bearing kidneys. Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Kidney transplantation: the use of living donors with renal artery lesions.

    Nahas, W C; Lucon, A M; Mazzucchi, E; Scafuri, A G; Neto, E D; Ianhez, L E; Arap, S


    A shortage of organs for transplantation has forced surgeons to optimize the use of marginal organs, such as kidneys with arterial disease. We present a retrospective study of the outcome of donors with renal artery disease and recipients of kidneys from living related and unrelated donors. Kidneys with vascular abnormalities from healthy living donors were grafted into 11 recipients. These kidney transplants comprised 1.8% of those performed at our institution. The vascular abnormalities were aneurysms in 3 cases, atherosclerotic lesions in 4 and fibromuscular dysplasia in 4. After nephrectomy all abnormalities were corrected under hypothermic conditions during bench surgery except in 3 cases of ostial atherosclerotic plaque, which was left in the donors. The renal artery was anastomosed to the external iliac artery in 5 cases and to the internal iliac artery in 6. The ureter was reimplanted using an extravesical technique. All patients had immediate diuresis and no delayed post-transplant graft dysfunction was observed. One patient died of an unrelated cause and 3 had post-transplant graft function loss due to acute vasculopathy in 1, post-diarrhea with acute arterial thrombosis in 1 and recurrence of the hemolytic-uremic syndrome in 1. All remaining patients are well with median serum creatinine of 1.4 mg./dl. (normal 0.4 to 1.4). All donors are well and normotensive with normal renal function. The use of kidneys with arterial disease from living donors with unilateral disease is safe. Complete informed consent regarding the risks and benefits by donor and recipient is mandatory.

  2. Vascular complications following 1500 consecutive living and cadaveric donor renal transplantations: A single center study

    Salehipour Mehdi


    Full Text Available The aim of this study was to document vascular complications that occurred fol-lowing cadaveric and living donor kidney transplants in order to assess the overall incidence of these complications at our center as well as to identify possible risk factors. In a retrospective cohort study, 1500 consecutive renal transplant recipients who received a living or cadaveric donor kidney between December 1988 and July 2006 were evaluated. The study was performed at the Nemazee Hospital, Shiraz, Iran. The assessment of the anatomy and number of renal arteries as well as the incidence of vascular complications was made by color doppler ultrasonography, angiography, and/or surgical exploration. Clinically apparent vascular complications were seen in 8.86% of all study patients (n = 133 with the most frequent being hemorrhage (n = 91; 6.1% followed by allo-graft renal artery stenosis (n = 26; 1.7%, renal artery thrombosis (n = 9; 0.6%, and renal vein thrombosis (n = 7; 0.5%. Vascular complications were more frequent in recipients of cadaveric organs than recipients of allografts from living donors (12.5% vs. 7.97%; P= 0.017. The occurrence of vascular complications was significantly more frequent among recipients of renal allografts with multiple arteries when compared with recipients of kidneys with single artery (12.3% vs. 8.2%; P= 0.033. The same was true to venous complications as well (25.4% vs. 8.2%; P< 0.001. Our study shows that vascular complications were more frequent in allografts with multiple renal blood vessels. Also, the complications were much less frequent in recipients of living donor transplants.

  3. Outcome of renal transplantation from a donor with polycystic kidney disease.

    Migone, Silvia Regina da Cruz; Bentes, Camila Guerreiro; Nunes, Débora Bacellar Cruz; Nunes, Juliana Bacellar Cruz; Pinon, Rodolfo Marcial da Silva; Silva, Thales Xavit Souza E


    Faced with the long waiting list for a kidney transplant, the use of donors with expanded criteria, like polycystic kidneys, is an option that aims to increase in a short time the supply of kidneys for transplant. This report of two cases of transplants performed from a donor with polycystic kidneys showed promising results, and the receptors evolved with good renal function, serum creatinine measurements within the normal range and with adequate glomerular filtration rate, evaluated over a period of four years post transplant. This fact confirms that the option of using donors with polycystic kidneys is safe and gives good results. Resumo Diante da longa fila de espera por um transplante renal, a utilização de doadores com critério expandido, a exemplo de rins policísticos, torna-se uma opção que visa aumentar a oferta de rins para transplante a curto prazo. O presente relato de dois casos de transplantes realizados a partir de um doador com rins policísticos apresentou resultado promissor, tendo os receptores evoluído com boa função renal, dosagens de creatinina sérica dentro da faixa de normalidade e com taxa de filtração glomerular adequada, avaliados num período de quatro anos pós-transplante. Isto confirma que a opção da utilização de doadores com rins policísticos é segura e apresenta bons resultados.

  4. Early renal failure after domino liver transplantation using organs from donors with primary hyperoxaluria type 1.

    Saner, Fuat H; Treckmann, Juergen; Pratschke, Johann; Arbogast, Helmut; Rahmel, Axel; Vester, Udo; Paul, Andreas


    Organ shortage is responsible for high mortality rates of patients awaiting liver transplantation (LT). Domino transplantation has had reported success in patients with metabolic disorders. Primary hyperoxaluria type 1 (PH1) is a rare metabolic disorder. There are a few case reports that suggest that PH1 livers originating from donors that have undergone combined liver-kidney transplantation can be successfully used for domino transplantation. In the last decade, five patients received a domino liver transplant from patients with PH1 in the EUROTRANSPLANT region. In this study, we report the clinical course and outcome of these five patients who were received a domino graft transplant. All patients, with the exception of one, suffered from multifocal hepatocellular carcinoma and underwent domino LT from patients undergoing combined liver-kidney transplantation for PH1. Within the first 4 weeks, all the domino recipients developed dialysis-dependent kidney failure despite good liver function. Four of the five patients died. The only survivor underwent retransplantation due to hepatic artery thrombosis. Twenty months after transplantation, this patient is doing well and has had no recurrence of hepatocellular carcinoma. Domino LT using donors with PH1 results in early renal failure and cannot be recommended for transplantation unless preventive strategies have been identified.

  5. Early outcome in renal transplantation from large donors to small and size-matched recipients - a porcine experimental model

    Ravlo, Kristian; Chhoden, Tashi; Søndergaard, Peter


    Kidney transplantation from a large donor to a small recipient, as in pediatric transplantation, is associated with an increased risk of thrombosis and DGF. We established a porcine model for renal transplantation from an adult donor to a small or size-matched recipient with a high risk of DGF...... and studied GFR, RPP using MRI, and markers of kidney injury within 10 h after transplantation. After induction of BD, kidneys were removed from ∼63-kg donors and kept in cold storage for ∼22 h until transplanted into small (∼15 kg, n = 8) or size-matched (n = 8) recipients. A reduction in GFR was observed...

  6. Cytomegalovirus disease in a renal transplant recipient: the importance of pre-transplant screening of the donor and recipient

    Ahmed H Mitwalli


    Full Text Available A 16-year-old female patient who was born with a single kidney developed chronic kidney disease during her early childhood due to reflux nephropathy and recurrent urinary tract infection. She progressed to end-stage renal disease (ESRD and was commenced on renal replacement therapy in the form of peritoneal dialysis in May 2011. Subsequently, she underwent living unrelated donor kidney transplantation in China. She was hospitalized soon after returning to Saudi Arabia for management of high-grade fever, shortness of breath, and deterioration of renal function, which was found to be due to cytomegalovirus (CMV disease, proved by kidney biopsy and presence of high level of anti-CMV immunoglobulins. Allograft biopsy showed mature viral particles sized between 120 and 149 nm in the nuclei of the glomerular endothelial cells. The patient was treated with valgancyclovir and specific CMV immunoglobulin, as well as by reducing and even stopping the dose of tacrolimus and mycophenolate. Despite all these measures, her condition continued to deteriorate and she finally died. Our study emphasizes that unrelated renal transplantation, especially if unplanned and improperly prepared, is a very risky procedure that might transfer dangerous diseases and increase the morbidity and mortality of the patients. We strongly stress the need for mandatory and proper screening for CMV carrier status among donors as well as recipients prior to transplantation. Also, a recommendation is made to reject CMV-positive donors.

  7. Retrospective analysis of 100 consecutive patients undergoing related living donor renal transplantation.

    Diethelm, A G; Sterling, W A; Aldrete, J S; Shaw, J F; Morgan, J M


    One hundred consecutive patients receiving related donor kidneys were analyzed in regards to graft and patient survival, morbidity, mortality, histocompatibility and rehabilitation. The average followup was 3 years and 2 months with a minimum post transplant evaluation of one year. Donor morbidity was minimal and the mortality nil. Recipient mortality was 17%, all of which occurred after the first two post transplant months. The most serious life threatening complications after transplantation were due to infection. The greatest morbidity was secondary to aseptic necrosis. The overall graft survival at one year was 94%, 2 years--87%, 3 years--81% and 4 and 5 years--72%. Separation of patients according to tissue typing revealed 95% of recipients with A and B matched kidneys to be alive 5 years later compared to 55% of patients receiving C and D matched kidneys. Rehabilitation was good to excellent in 76% of the living patients and poor in only 4%. These results suggest related donor renal transplantation to be the treatment of choice for patients with chronic renal failure excluding only those individuals who are exceptionally high risks in terms of morbidity and mortality.

  8. A Double Blind Randomized Clinical Trial of Remote Ischemic Conditioning in Live Donor Renal Transplantation.

    Nicholson, Michael L; Pattenden, Clare J; Barlow, Adam D; Hunter, James P; Lee, Gwyn; Hosgood, Sarah A


    Ischemic conditioning involves the delivery of short cycles of reversible ischemic injury in order to induce protection against subsequent more prolonged ischemia. This randomized controlled trial was designed to determine the safety and efficacy of remote ischemic conditioning (RC) in live donor kidney transplantation.This prospective randomized clinical trial, 80 patients undergoing live donor kidney transplantation were randomly assigned in a 1:1 ratio to either RC or to a control group. RC consisted of cycles of lower limb ischemia induced by an arterial tourniquet cuff placed around the patient's thigh. In the RC treatment group, the cuff was inflated to 200 mm Hg or systolic pressure +25 mm Hg for 4 cycles of 5 min ischemia followed by 5 min reperfusion. In the control group, the blood pressure cuff was inflated to 25 mm Hg. Patients and medical staff were blinded to treatment allocation. The primary end-point was renal function measured by estimated glomerular filtration rate (eGFR) at 1 and 3 months posttransplant.Donor and recipient demographics were similar in both groups (P protocol described here, did not improve renal function after live donor kidney transplantation.

    Graft failure due to chronic rejection is greater among renal transplant patients with donor-specific antibody (DSA) than among DSA-free patients. For patients dependent on deceased donor transplantation, preoperative desensitization to eliminate DSAs may be impractical. We speculated that perioperative desensitization might eliminate preexisting DSAs and prevent de novo DSAs and improve graft outcomes. We report that brief perioperative desensitization using either intravenous immunoglobulin (IVIG) or plasmapheresis/IVIG (PP/IVIG) treatment improves clinical outcomes among patients with positive crossmatches. Immediately following deceased donor transplantation, 235 renal recipients were assigned points for PRA and flow crossmatches (FCXM): delayed graft function (DGF) ≤ 1 point received standard therapy; 2 points received high-dose IVIG; and ≥3 points received PP/IVIG. The DSAs were serially monitored by single antigen bead luminex for 1 year. Five-year clinical outcomes were determined from the chart review. All desensitized patients had preoperatively positive FCXM with DSA. Rejection was more common (P desensitized than nonsensitized groups. However, overall graft survivals were similar between the groups (P = not significant) and superior to historic untreated patients (P 90% in all desensitizated patients with DSA elimination as well as PP/IVIG patients with residual DSA. In contrast, IVIG patients with persistent DSA had poorer graft survival (45%, P desensitization improved overall graft survival of sensitized patients compared to historic untreated patients. Plasmapheresis/IVIG had greater impact on DSA eradication and graft survival than IVIG alone. © 2016, NATCO.

  12. Survival of living donor renal transplant recipients in Sri Lanka: a single-center study.

    Galabada, Dinith Prasanna; Nazar, Abdul L M; Ariyaratne, Prasad


    Chronic kidney disease is one of the main public health concerns in Sri Lanka. In comparison with dialysis, successful kidney transplantation improves both patient survival and quality of life, relieves the burden of dialysis in patients suffering from end-stage renal disease and decreases the cost of healthcare to the society and government. The objective of this retrospective cohort study was to evaluate graft and patient survival rates in patients who were transplanted from living donors at the Nephrology Unit of the National Hospital of Sri Lanka from January 2005 to January 2011. Data were collected using an interviewer-administered questionnaire and through a review of past medical records. The Kaplan-Meier method was used to determine the survival rate, the log rank test was used to compare survival curves and the Cox proportional hazard model was used for multivariate analysis. Mean follow-up was 26.44±16.6 months. The five-year death-censored graft survival of kidney transplant recipients from living donors in our center was 93.5% and the five-year patient survival was 82.2%, which is comparable with other transplant programs around the world. The number of acute rejection episodes was an independent risk factor for graft survival. Delayed graft function, younger recipient age and unknown cause of end-stage renal disease were found to be risk factors for graft failure but after adjusting for confounding factors, and the difference was not apparent.

  14. Outcome of deceased donor renal transplantation - A single-center experience from developing country

    Himanshu V Patel


    Full Text Available Renal transplantation (RTx is considered as the best therapeutic modality for patient suffering from end-stage renal disease (ESRD. Dearth of donor kidneys is a major problem everywhere, and deceased donor renal transplantation (DDRTx is seen as at least a partial solution. Even so, DDRTx accounts for only less than 4% of RTx in India. We report our 6-year single-center experience on DDRTx vis-à-vis patient/graft survival, graft function in terms of serum creatinine (SCr, rejection episodes, and delayed graft function (DGF. Between January 2005 and March 2011, 236 DDRTx were performed. Majority of the donors were those with brain death due to road traffic/cerebrovascular accidents. The commonest recipient diseases leading to ESRD were chronic glomerulonephritis (42.8%, diabetes (12.7%, and hypertension (10.6%. Mean recipient age was 36.2 ± 14.2 years; 162 were males and 74 were females. Mean donor age was 45.3 ± 17.13 years; 144 were males and 92 were females. Mean dialysis duration pre-transplantation was 18.5 ± 2.5 months. All recipients received single-dose rabbit-anti-thymocyte globulin induction and steroids, calcinueurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. Delayed graft function was observed in 29.6% patients and 22% had biopsy-proven acute rejection. Over the mean follow-up of 2.18 ± 1.75 years, patient and graft survival rates were 74.57% and 86.8%, respectively, with mean SCr of 1.42 ± 0.66 mg%. DDRTx achieves acceptable graft function with patient/graft survival, encouraging the use of this approach in view of organ shortage.

  15. First documented case of successful kidney transplantation from a donor with acute renal failure treated with dialysis.

    Bacak-Kocman, Iva; Peric, Mladen; Kastelan, Zeljko; Kes, Petar; Mesar, Ines; Basic-Jukic, Nikolina


    There is a widening gap between the needs and possibilities of kidney transplantation. In order to solve the problem of organ shortage, the selection criteria for kidney donors have been less stringent over the last years. Favorable outcome of renal transplantation from deceased donors with acute renal failure requiring dialysis may have an important role in expanding the pool of donors. We present the case of two renal transplantations from a polytraumatized 20-years old donor with acute renal failure requiring dialysis. One recipient established good diuresis from the first post-transplant day and did not require hemodialysis. The second recipient had delayed graft function and was treated with 8 hemodialysis sessions. The patient was discharged with good diuresis and normal serum creatinine. After two years of follow-up, both recipients have normal graft function. According to our experience, kidneys from deceased young donors with acute renal failure requiring dialysis may be transplanted, in order to decrease the number of patients on transplantation waiting lists.

  17. HLA class I donor-specific triplet antibodies detected after renal transplantation.

    Varnavidou-Nicolaidou, A; Doxiadis, I I N; Iniotaki-Theodoraki, A; Patargias, T; Stavropoulos-Giokas, C; Kyriakides, G K


    The purpose of this study was to investigate whether IgG, non-donor-specific anti-HLA class I antibodies (HLAabI) detected after renal transplantation recognize immunogenic amino acid triplets expressed on the foreign graft. In addition, we sought to evaluate the effect of these antibodies as well as other posttransplant HLAabI on graft outcome. Posttransplant sera from 264 renal recipients were tested for the presence of IgG HLAabI and HLA class II-specific alloantibodies (HLAabII) by ELISA. The HLAMatchmaker computer algorithm was used to define the HLA class I non-donor-specific antibodies, which seem to recognize immunogenic amino acid triplets. Donor-specific triplet antibodies (DSTRab) were detected in 16 of 22 (72.7%) recipients based on at least one HLA-A or -B mismatched antigen with the donor. DSTRab were found either without (n = 7) or with (n = 9) HLA donor-specific antibodies (HLA-DSA). The presence of DSTRab alone in the periphery was associated with acute rejection, whereas the presence of both DSTRab and HLA-DSA was associated with chronic rejection and graft failure.

  18. Evaluation of factors causing delayed graft function in live related donor renal transplantation

    Sharma A


    Full Text Available To determine the incidence and determinants of delayed graft function due to post-transplant acute tubular necrosis in live related donor renal transplantation. This is a retrospective study of 337 recipients of live related donor renal graft performed between1986 and 2006. Of these recipients, 24 (7.1% subjects developed delayed graft function with no evidence of acute rejection, cyclosporin toxicity, vascular catastrophe or obstructive cause and had evidence of acute tubular necrosis (ATN Group. These subjects were compared with recipients (n= 313, 92.9% who had no clinical or biochemical evidence of ATN. Mean age, and gender distribution of recipients was similar in the two groups (ATN group 35.7 ± 8.3, non-ATN group 34.3 ± 7.5, P= 0.43. Gender distribution of the recipients (men 279, 89.1% vs. 21, 87.5%, P= 0.80 as well as donors (women 221, 70.6% vs. 18, 75.0%, P= 0.75 was also similar. In ATN group as compared with non-ATN group the donor age was significantly greater (56.6 ± 8.3 vs. 46.6 ± 11.2 years, P< 0.0001. There was marginal difference in pre-operative systolic BP (154.5 ± 18.3 vs. 147.4 ± 20.2 mm Hg, P= 0.077 and significant difference in diastolic BP (87.8 ± 9.5 vs. 83.4 ± 11.4 mmHg, P= 0.041. Incidence of multiple renal arteries was similar (16.7% vs. 7.3%, P= 0.22. The warm ischemia time was significantly greater in ATN group (33.3 ± 6.2 min as compared to non-ATN group (30.4 ± 5.7 min, P= 0.042. Duration of hospital stay was more in ATN group (19.9 ± 6.7 vs. 16.8 ± 8.4 days, P= 0.04 but there was no difference in 1 year survival (284 subjects, 90.7% vs. 21 subjects, 87.5%, P= 0.873. This study shows that greater donor age, higher baseline diastolic BP and greater warm ischemia time are major determinants of delayed graft function due to acute tubular necrosis after related donor renal transplantation.

  19. The use of the inferior epigastric artery for accessory lower polar artery revascularization in live donor renal transplantation.

    El-Sherbiny, M; Abou-Elela, A; Morsy, A; Salah, M; Foda, A


    This study describes the surgical technique and outcomes of live donor renal allografts with multiple arteries in which the lower polar artery was anastomosed to the inferior epigastric artery after declamping. Between 1988 and 2004, 477 consecutive live donor renal transplants were performed, including 429 with single and 48 with multiple arteries. Anastomosis of the lower polar artery to the inferior epigastric artery was used for 15 grafts with multiple arteries. Successful revascularization of all areas of the transplanted graft was confirmed by Doppler ultrasonography in most patients and radionuclide renal scanning +/- MRA in some patients. In live donor renal transplantation with multiple arteries, the anastomosis of the lower polar artery to the inferior epigastric artery after declamping avoids prolongation of the ischemia time that occurs with other surgical and microsurgical techniques of intracorporeal and ex vivo surgeries.

  20. Successful renal transplantation from a brain-dead deceased donor with head injury, disseminated intravascular coagulation and deranged renal functions

    P P Ghuge


    Full Text Available Deceased donors (DDs with the brain death due to head injury are the major source of organs for transplantation. The incidence of post-head injury disseminated intravascular coagulation (DIC ranges from 24% to 50%. Many centers do not accept organs from donors with DIC due to increased risk of primary graft non-function and/or high chances of morbidity/mortality. We performed two successful renal transplants from a DD with head injury with DIC and deranged renal function. One of the recipients developed transient thrombocytopenia, but there was no evidence of DIC or delayed graft functions in either of the recipients. Over a follow-up of 1 month, both are doing well with stable graft function and hematological profile. Thus, a carefully selected DD with severe DIC even with deranged renal function is not a contraindication for organ donation if other risk factors for primary non-function are excluded. This approach will also help in overcoming organ shortage.

  1. Prognostic utility of preimplantation kidney biopsy from deceased older donors in first year post-transplant renal function.

    Preimplantation renal biopsy provides potentially valuable information about post-transplant renal function. To assess the prognostic value of preimplantation kidney biopsy from older donors in determining 1-year post-transplant estimated glomerular filtration rate MDRD-4 (eGFR). We evaluated a cohort of 124 renal transplant recipients from deceased donors ≥60 years old, performed at our center between March 2008 and May 2012. Biopsies were assessed by applying the score proposed by O'Valle et al. The overall score was stratified into 3 levels: 0-3, 4-5 and 6-8 points. Kidneys scoring > 8 points were discarded. A total of 77% of the donors were ≥70 years. One year post-transplant, mean eGFR (SD) was lower in transplant recipients with 6-8 points (38.5 [14.1] mL/min/1.73m(2)) than in the group scoring 4-5 points (46.3 [15.7] [p=0.03]) and the group scoring 0-3 (49.6 [12.5] [P=.04]). Seven patients (19%) had eGFR renal biopsy were associated with a worse 1-year post-transplant eGFR. Delayed graft function and acute rejection were significant risk factors for 1-year post-transplant low eGFR. Copyright © 2015 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U.

  2. Renal mass dosing and graft function in children transplanted from pediatric donors.

    de Petris, L; Faraggiana, Tullio; Rizzoni, Gianfranco


    It has been suggested that "renal mass dosing" may affect graft evolution. Between 1993 and 1999, 43 children, aged 4-17 years, received 43 pediatric cadaveric grafts. The ratio between graft volume (calculated by ultrasound within the first 24 h from transplantation, by ellipsoid formula) and the recipient's body surface area (BSA) ranged between 14.1 and 110 ml/m(2). Three groups were identified: group 1, 14-29 ml/m(2) (13 patients); group 2, 30-39 ml/m(2) (16 patients); group 3, 40-110 ml/m(2) (14 patients). As a consequence of the different renal volume increments in the three groups during the first year after transplant, no differences in the absolute renal volume were observed at the end of follow-up. The average follow-up was 38 months (range 12-80). In the 37 routine graft biopsies, performed on average 13 months after transplantation and with more than five glomeruli, maximum mean glomerular diameters were mostly above normal values. There were no significant differences among the three groups. At the end of follow-up, the three groups did not differ in microalbuminuria, proteinuria, glomerular function or in incidence of hypertension. From this retrospective study, we conclude that the very wide range of renal mass dosing did not cause differences in medium-term graft evolution. A longer follow-up will be necessary to ascertain the possible influence of disproportion between pediatric donors and recipients, on a long-term graft outcome.

  3. Renal transplantation across the donor-specific antibody barrier: Graft outcome and cancer risk after desensitization therapy

  4. The Occurrence of Primary Hepatic Adenoma in Deceased Donor Renal Transplant Recipient

    Yu-Tso Liao


    Full Text Available Main findings: We reported a case of new-onset, multi-focal hepatic adenoma in an 18 year-old man with no classic risk factors occurring forty months after a renal transplant from a cadaver donor. Histopathology of the adenoma was examined and genotype and phenotype were also analyzed. Histopathologic examination of the adenoma showed no malignancy. Genotype and phenotype analysis revealed no HNF1α or β-catenin gene mutations and no inflammatory infiltration. The patient was well and disease-free postoperatively. Case hypothesis: Hepatic adenoma occurs mostly in those taking oral contraceptives or androgenic-anabolic steroids or in those with hereditary diseases. Hepatic adenoma in a renal transplant recipient is rare and has only been reported in one case with glycogen storage disease type Ia. Immunosuppressive treatment might have contributed to the development of the neoplasm. Promising future implications: Although malignant change occurs most often in β-catenin gene mutation hepatic adenoma, surgical resection of the adenoma in a patient under immunosuppressive therapy should be considered in order to avoid the possibility of malignant transformation or hemorrhagic rupture.

  5. Ex Vivo Normothermic Perfusion Induces Donor-Derived Leukocyte Mobilization and Removal Prior to Renal Transplantation

    John P. Stone


    Discussion: We demonstrate that ex vivo normothermic perfusion initiates an inflammatory cytokine storm and release of mitochondrial and genomic DNA. This is likely to be responsible for immune cell activation and mobilization into the circuit prior to transplantation. Interestingly this did not have an impact on renal function. These data therefore suggest that normothermic perfusion can be used to immunodeplete and to saturate the pro-inflammatory capacity of donor kidneys prior to transplantation.

  6. Living donor transplant options in end-stage renal disease patients with ABO incompatibility

    Santosh S Waigankar


    Full Text Available Introduction: The options available to CKD 5 patients with donor shortage due to incompatibilities is to either get enlisted in cadaver transplant program or opt for three other alternatives viz; ABO-incompatible transplant (ABO-I, ABO-incompatible transplant with Rituximab (ABO-R or paired-kidney exchange transplant (PKE. At our institute we have performed ABO-I, ABO-R and PKE transplants and we are presenting the results of these transplants performed at our institution. Here, we report our experiences of living donor kidney transplantation in highly sensitized patients. Objective: To review the options available to CKD 5 patients with incompatible donor. Materials and Methods: Between January 2008 and June 2011, 7 PKE, 26 ABO-I and 7 ABO-R transplants were carried out at our institute. Evaluation of both the recipients and donors involved biochemical, serological and radiological investigations. In case of PKE, recipients were operated simultaneously in different operation theaters. In ABO-I splenectomy was done while in ABO-R was given. Post-transplant the recipient management protocol remained the same. Expenditure following each transplant was calculated. Results: The graft and patient survival of ABO-I, ABO-R and PKE transplants 12-18 months after transplant were 78.9%:80%, 85.7%:85.7% and 100%:100%, respectively. Conclusions: The inclusion of Rituximab in the transplant protocol appears promising. The existing donor shortage could be addressed by encouraging other options like PKE. The limiting factor for ABO-R and PKE transplants is time and cost, respectively. The decision depends on the informed consent between the patient and the nephrologists.

  9. Deceased-Donor Apolipoprotein L1 Renal-Risk Variants Have Minimal Effects on Liver Transplant Outcomes.

    Casey R Dorr

    Full Text Available Apolipoprotein L1 gene (APOL1 G1 and G2 renal-risk variants, common in populations with recent African ancestry, are strongly associated with non-diabetic nephropathy, end-stage kidney disease, and shorter allograft survival in deceased-donor kidneys (autosomal recessive inheritance. Circulating APOL1 protein is synthesized primarily in the liver and hydrodynamic gene delivery of APOL1 G1 and G2 risk variants has caused hepatic necrosis in a murine model.To evaluate the impact of these variants in liver transplantation, this multicenter study investigated the association of APOL1 G1 and G2 alleles in deceased African American liver donors with allograft survival. Transplant recipients were followed for liver allograft survival using data from the Scientific Registry of Transplant Recipients.Of the 639 liver donors evaluated, 247 had no APOL1 risk allele, 300 had 1 risk allele, and 92 had 2 risk alleles. Graft failure assessed at 15 days, 6 months, 1 year and total was not significantly associated with donor APOL1 genotype (p-values = 0.25, 0.19, 0.67 and 0.89, respectively.In contrast to kidney transplantation, deceased-donor APOL1 G1 and G2 risk variants do not significantly impact outcomes in liver transplantation.

  10. Comparison of nutritional parameters after abo incompatible living donor renal transplantation

    Joon Seok Oh


    By the end of the first year, serum hemoglobin, calcium, albumin, HDL, bilirubin, AST, ALT were increased statistically. But serum phosphate, globulin were decreased statistically. In conclusion, successful ABO incompatible living donor kidney transplantation would restore a normal nutritional status even though the patients were performed plasmapheresis during the pre-transplant period.

  11. Successful unintentional ABO-incompatible renal transplantation: Blood group A1B donor into an A2B recipient.

    Fadeyi, Emmanuel A; Stratta, Robert J; Farney, Alan C; Pomper, Gregory J


    To report a successful unintentional transplantation of a deceased donor kidney from an "incompatible" A1B donor into a recipient who was blood group A2B with unsuspected preformed anti-A1 antibodies. The donor and recipient were both typed for ABO antigens. The recipient was tested for ABO and non-ABO antibodies. The recipient was typed for HLA class I and class II antigens, including HLA antibody screen. The T-and B-flow cytometry crossmatch test was performed using standard protocol. The donor-recipient pair was a complete six-antigen human leukocyte antigen mismatch, but final T- and B-flow cytometry cross-match tests were compatible. The recipient was a 65-year-old woman with a medical history of end-stage renal disease secondary to diabetic nephropathy who underwent kidney transplantation from a 46-year-old brain-dead standard criteria donor. The recipient's RBCs were negative with A1 lectin, and the recipient was thus typed as an A2 subgroup. Anti-A1 could be demonstrated in the recipient's plasma. The donor's RBCs were positive with A1 lectin, thereby conferring an A1 blood type. It is safe to transplant across the A1/A2 blood group barrier provided that the preformed antibodies are not reactive at 37°C and with anti-human globulin.

  12. [Renal transplantation and urinary lithiasis].

    Lechevallier, E; Saussine, C; Traxer, O


    Renal lithiasis in renal donors is rare. A renal stone in a donor, or in a renal transplant, is not a contraindication for harvesting nor transplantation. If possible, the stone must be removed at the time of the transplantation. The risk of lithiasis is increased in the renal transplant recipient, with a frequency of 2-6%. Metabolic abnormalities for lithiasis are frequent and can be induced by the immunosuppressive treatment, anticalcineurins. Lithiasis can have a poor prognosis in the renal recipient with a risk for infection or renal dysfunction. Small (renal transplant can be followed-up. Stones of 0.5-1.5cm need an extracorporeal lithotripsy with a previous safety JJ stent. Stones greater than 1.5cm can be treated by ureteroscopy or percutaneous surgery.

  13. Ethnic differences in HLA antigens in Chilean donors and recipients: data from the National Renal Transplantation Program.

    Droguett, M A; Beltran, R; Ardiles, R; Raddatz, N; Labraña, C; Arenas, A; Flores, J; Alruiz, P; Mezzano, S; Ardiles, L


    To describe HLA antigen distribution, looking for possible markers of renal disease in Mapuche and non-Mapuche people in the renal transplantation program, we reviewed data from 1297 histocompatibility studies of the Chilean national renal transplantation program (421 donors and 876 recipients), performed between 2000 and 2005. Mapuche people were classified according to their family surnames. The most frequent antigens found among the total Chilean population were A2 (48%), A19 (33%), B16 (33%), B35 (26%), DR4 (38%), and DR6 (28%), without significant differences between donors and recipients. Among the 114 individuals (9%) classified as Mapuche, the most frequent antigens were A28 (49%), A2 (44%), B16 (63%), B35 (24%), DR4 (48%), and DR8 (30%), with A28/B16/DR4 as the most common haplotype. In contrast, A28, B16, DR4, and DR8 were significantly more frequent in Mapuche compared with non-Mapuche people. B8 was significantly more frequent in Mapuche recipients than in non-Mapuche recipients and Mapuche donors. The higher frequency of some HLA antigens in Mapuche people was confirmed, possibly corresponding to ethnic markers. The special concentration of B8 among Mapuche recipients might represent a genetic factor predisposing to chronic renal disease in this human group.

    El-Husseini, Amr A; Foda, Mohamed A; Osman, Yasser M; Sobh, Mohamed A


    To study the characteristics and the predictors of survival observed in our pediatric live-donor renal transplant recipients with an allograft that functioned for more than 10 yr. One hundred fifteen children underwent renal transplantation between 1976 and 1995. Of these, 30 had functioning allografts for more than 10 yr (range, 11-18). The patients included 18 males and 12 females, with a mean age at transplantation of 13 yr (range, 5-18). Characteristics of the patients, data on graft survival, and determinants of outcome were obtained by reviewing all medical charts. At most recent follow-up (January 2005), the mean daily dose of azathioprine was 1.2 mg/kg (range, 1-2) and that of prednisone was 0.16 mg/kg (range, 0.1-0.2). Mean creatinine clearance was 72 mL/min per 1.73 m(2) (range, 45-112). Acute rejection occurred in 14 (47%) patients. Seven patients had one episode, five had two episodes, and two had three episodes of acute rejection. Three patients (10%) developed malignancy. A substantial proportion of patients (44%) were short, with a height standard deviation score (SDS) less than -1.88, which is below the third percentile for age and gender. One quarter of the patients, more commonly the females, were obese. Other complications included osteoporosis in 16 (53%) patients, avascular bone necrosis in four (13%), post-transplantation diabetes mellitus in three (10%), and hypertension in 18 (60%). Twelve (40%) patients were married and 27% had children post-transplantation. The independent determinants of long-term graft survival were acute rejection and post-transplant hypertension. Despite good renal function, long-term pediatric renal transplant survivors are at risk of significant morbidity. The determinants of long-term graft survival are acute rejection and post-transplant hypertension.

    Kosmoliaptsis, V; Salji, M; Bardsley, V; Chen, Y; Thiru, S; Griffiths, M H; Copley, H C; Saeb-Parsy, K; Bradley, J A; Torpey, N; Pettigrew, G J


    Histological assessment of baseline chronic kidney injury may discriminate kidneys that are suitable for transplantation, but has not been validated for appraisal of donation after circulatory death (DCD) kidneys. 'Time-zero' biopsies for 371 consecutive, solitary, deceased-donor kidneys transplanted at our center between 2006 and 2010 (65.5% DCD, 34.5% donation after brain death [DBD]) were reviewed and baseline chronic degenerative injury scored using Remuzzi's classification. High scores correlated with donor age and extended criteria donors (42% of donors), but the spectrum of scores was similar for DCD and DBD kidneys. Transplant outcomes for kidneys scoring from 0 to 4 were comparable (1 and 3 year graft survival 95% and 92%), but were much poorer for kidneys scoring ≥5, with 1 year graft survival only 73%, and 12.5% suffering primary nonfunction. Critically, high Remuzzi scores conferred the same survival disadvantage for DCD and DBD kidneys. On multi-variable regression analysis, time-zero biopsy score was the only independent predictor for graft survival, whereas one-year graft estimated glomerular filtration rate (eGFR) correlated with donor age and biopsy score. In conclusion, the relationship between severity of chronic kidney injury and transplant outcome is similar for DCD and DBD kidneys. Kidneys with Remuzzi scores of ≤4 can be implanted singly with acceptable results.

  16. CYP3A5 polymorphism effect on cyclosporine pharmacokinetics in living donor renal transplant recipients: analysis by population pharmacokinetics.

    Song, Joohan; Kim, Myeong Gyu; Choi, Boyoon; Han, Na Young; Yun, Hwi-Yeol; Yoon, Jeong-Hyun; Oh, Jung Mi


    Cyclosporine is often used to prevent allograft rejection in renal transplant recipients. However, cyclosporine has a narrow therapeutic window and large variability in its pharmacokinetics. Individual characteristics and genetic polymorphisms can cause the variation. Hence, it is important to determine the cause(s) of the variation in cyclosporine pharmacokinetics. To our knowledge, this is the first reported population pharmacokinetic study of cyclosporine in living donor renal transplant recipients that considered the genetic polymorphism as a covariate. To build a population pharmacokinetic model of cyclosporine in living donor renal transplant recipients and identify covariates including CYP3A5*3, ABCB1 genetic polymorphisms that affect cyclosporine pharmacokinetic parameters. Clinical characteristics and cyclosporine concentration data for 69 patients who received cyclosporine-based immunosuppressive therapy after living donor renal transplantation were collected retrospectively for up to 400 postoperative days. CYP3A5*1/*3 and ABCB1C1236T, G2677T/A, C3435T geno-typing was performed. A population pharmacokinetic analysis was conducted using a NONMEM program. After building the final model, 1000 bootstrappings were performed to validate the final model. In total, 2034 blood samples were collected. A 1-compartment open model with first-order absorption and elimination was chosen to describe the pharmacokinetics of cyclosporine. A population pharmacokinetic analysis showed that postoperative days, sex, and CYP3A5 genotype significantly affected the pharmacokinetics of cyclosporine. The final estimate of mean clearance was 56 L/h, and the mean volume of distribution was 4650 L. The interindividual variability for these parameters was 22.98% and 51.48%, respectively. Using the present model to calculate the dose of cyclosporine with CYP3A5 genotyping can be possible for the patients whose cyclosporine concentration is not within the therapeutic range even with

  17. Desensitization for renal transplantation: depletion of donor-specific anti-HLA antibodies, preservation of memory antibodies, and clinical risks.

    Rogers, Natasha M; Eng, Hooi S; Yu, Raymond; Kireta, Svjetlana; Tsiopelas, Eleni; Bennett, Greg D; Brook, Nicholas R; Gillis, David; Russ, Graeme R; Coates, P Toby


    Desensitization protocols reduce donor-specific anti-HLA antibodies (DSA) and enable renal transplantation in patients with a positive complement-dependent cytotoxic cross-match (CDC-CXM). The effect of this treatment on protective antibody and immunoglobulin levels is unknown. Thirteen patients with end-stage renal disease, DSA and positive CDC-CXM underwent desensitization. Sera collected pre- and post-transplantation were analysed for anti-tetanus and anti-pneumococcal antibodies, total immunoglobulin (Ig) levels and IgG subclasses and were compared to healthy controls and contemporaneous renal transplant recipients treated with standard immunosuppression alone. Ten patients developed negative CDC-CXM and enzyme-linked immunosorbent assay (ELISA) and underwent successful transplantation. Eight recipients achieved good graft function without antibody-mediated or late rejection, BK virus or cytomegalovirus infection. One patient had primary non-function due to recurrent oxalosis, and one patient with immediate graft function died from septicaemia. Seven recipients required post-operative transfusion and three developed septicaemia. DSA remained negative by ELISA at 12 months, but were detectable by Luminex(®) . Anti-tetanus and anti-pneumococcal antibodies, total Ig and IgG subclasses were below the normal range but comparable to levels in renal transplant recipients who had not undergone desensitization. Desensitization protocols effectively reduce DSA and allow successful transplantation. Post-operative bleeding and short-term infectious risk is increased. Protective antibody and serum immunoglobulin levels are relatively preserved. © 2010 The Authors. Journal compilation © 2010 European Society for Organ Transplantation.

  18. Survival of cadaveric renal transplant grafts from young donors and in young recipients.

    Arbus, G S; Rochon, J; Thompson, D


    Evidence from multicenter registries has suggested that cadaveric renal graft survival is poorer when either the recipient or the donor is very young. We therefore analyzed our results from a single pediatric center. There was a significant correlation between greater recipient age and improved cadaveric graft (P = 0.002) and patient (P = 0.0009) survival. The age of the donor also appeared important, particularly in very young children, but became less so as donor age rose. Forty-four percent of recipients under 3 years old who received cadaveric kidneys from donors less than 4 years old lost their grafts as a result of renal thrombosis, ischemia, or technical problems, compared with only 3% of recipients over 9 years of age, whose grafts came from donors who were also over 9 years. The 1-year first cadaveric graft survival rates for these two age groups were 33% and 82% respectively. Our experience confirms the poor findings reported in very young recipients and with very young donors.

  19. Behaviour of non-donor specific antibodies during rapid re-synthesis of donor specific HLA antibodies after antibody incompatible renal transplantation.

    Nithya S Krishnan

    Full Text Available HLA directed antibodies play an important role in acute and chronic allograft rejection. During viral infection of a patient with HLA antibodies, the HLA antibody levels may rise even though there is no new immunization with antigen. However it is not known whether the converse occurs, and whether changes on non-donor specific antibodies are associated with any outcomes following HLA antibody incompatible renal transplantation.55 patients, 31 women and 24 men, who underwent HLAi renal transplant in our center from September 2005 to September 2010 were included in the studies. We analysed the data using two different approaches, based on; i DSA levels and ii rejection episode post transplant. HLA antibody levels were measured during the early post transplant period and corresponding CMV, VZV and Anti-HBs IgG antibody levels and blood group IgG, IgM and IgA antibodies were quantified.Despite a significant DSA antibody rise no significant non-donor specific HLA antibody, viral or blood group antibody rise was found. In rejection episode analyses, multiple logistic regression modelling showed that change in the DSA was significantly associated with rejection (p = 0.002, even when adjusted for other antibody levels. No other antibody levels were predictive of rejection. Increase in DSA from pre treatment to a post transplant peak of 1000 was equivalent to an increased chance of rejection with an odds ratio of 1.47 (1.08, 2.00.In spite of increases or decreases in the DSA levels, there were no changes in the viral or the blood group antibodies in these patients. Thus the DSA rise is specific in contrast to the viral, blood group or third party antibodies post transplantation. Increases in the DSA post transplant in comparison to pre-treatment are strongly associated with occurrence of rejection.

  20. Two Cases of Human T-Lymphotropic Virus Type I-Associated Myelopathy/Tropical Spastic Paraparesis Caused by Living-Donor Renal Transplantation

    Yasutaka Tajima


    Full Text Available In rare instances, recipients of organ transplants from human T-lymphotropic virus type I- (HTLV-I- positive donors reportedly developed neurologic symptoms due to HTLV-I-associated myelopathy (HAM. We present herein two cases of HAM associated with renal transplantation from HTLV-I seropositive living-donors. The first patient was a 42-year-old woman with chronic renal failure for twelve years and seronegative for HTLV-I. She underwent renal transplantation with her HTLV-I seropositive mother as the donor, and she developed HAM three years after the transplantation. The second patient was a 65-year-old man who had been suffering from diabetic nephropathy. He was seronegative for HTLV-I and underwent renal transplantation one year previously, with his HTLV-I seropositive wife as the donor. He developed HAM eight months after renal transplantation. Both cases showed neurological improvements after the immunomodulating therapies. We tried to shed some light on the understanding of immunological mechanisms of transplantation-associated HAM, focusing on therapeutic strategies based on the immunopathogenesis of the condition.

  1. Rupture of Renal Transplant

    Shona Baker


    Full Text Available Background. Rupture of renal allograft is a rare and serious complication of transplantation that is usually attributed to acute rejection, acute tubular necrosis, or renal vein thrombosis. Case Presentation. LD, a 26-year-old male with established renal failure, underwent deceased donor transplantation using kidney from a 50-year-old donor with acute kidney injury (Cr 430 mmol/L. LD had a stormy posttransplant recovery and required exploration immediately for significant bleeding. On day three after transplant, he developed pain/graft swelling and another significant haemorrhage with cardiovascular compromise which did not respond to aggressive resuscitation. At reexploration, the renal allograft was found to have a longitudinal rupture and was removed. Histology showed features of type IIa Banff 97 acute vascular rejection, moderate arteriosclerosis, and acute tubular necrosis. Conclusion. Possible ways of avoiding allograft rupture include use of well-matched, good quality kidneys; reducing or managing risk factors that would predispose to delayed graft function; ensuring a technically satisfactory transplant procedure with short cold and warm ischemia times; and avoiding large donor-recipient age gradients.

  2. Long-term outcome of intensive initial immunosuppression protocol in pediatric deceased donor renal transplantation.

    Olaitan, Oyedolamu K


    To report the long-term outcome of deceased donor kidney transplantation in children with emphasis on the use of an intensive initial immunosuppression protocol using R-ATG as antibody induction. Between January 1991 and December 1997, 82 deceased donor kidney transplantations were performed in 75 pediatric recipients. Mean recipient age at transplantation was 12.9 yr and the mean follow-up period was 12.6 yr. All patients received quadruple immunosuppression with steroid, cyclosporine, azathioprine, and antibody induction using R-ATG-Fresenius. Actual one, five, and 10 yr patient survival rates were 99%, 97%, and 94%, respectively; only one patient (1.2%) developed PTLD. Actual one, five, and 10 yr overall graft survival rates were 84%, 71%, and 50%, respectively; there were five cases (6%) of graft thrombosis and the actual immunological graft survival rates were 91%, 78%, and 63% at one, five, and 10 yr, respectively. The use of an intensive initial immunosuppression protocol with R-ATG as antibody induction is safe and effective in pediatric recipients of deceased donor kidneys with excellent immunological graft survival without an increase in PTLD or other neoplasms over a minimum 10-yr follow up.

  3. [Hemolytic anemia caused by graft-versus-host reaction in ABO-nonidentical renal transplants from blood group O donors].

    Peces, R; Díaz Corte, C; Navascués, R A


    Acute hemolytic anemia is one of the side effects associated with cyclosporin and tacrolimus therapy, and three mechanisms have been described to account for hemolytic anemia in patients receiving these drugs: drug induced hemolysis, autoimmune hemolysis and alloimmune hemolysis resulting from donor lymphocytes derived from the allograft (passenger lymphocyte syndrome). We report four cases of renal transplant recipients who developed alloimmune hemolytic anemia due to minor ABO incompatibility while under treatment with cyclosporin (two) and tacrolimus (two). The anti-erythrocyte antibodies responsible for hemolysis were of the IgG isotype and showed anti-A or anti-B specificity. These findings suggest that the hemolysis could be related to alloantibodies derived from the clonal development of donor B lymphocytes in the recipients (microchimerism). In summary, hemolytic anemia due to ABO-minor incompatibility occurs infrequently after renal transplantation. Risks are higher for patients A, B or AB blood group receiving an O blood group graft under treatment with cyclosporin or tacrolimus. Follow-up of these patients is warranted for the early detection and optimal management may be achieved by reduction of immunosuppression and change to mycophenolate mofetil.

    To assess the effect of the intraoperative use of terlipressin on splanchnic hemodynamics and postoperative renal function in patients undergoing liver transplantation. Open-label, prospective, randomized study. Single-center study. Thirty patients who underwent elective, living-donor liver transplantation with portal pressure >20 mm Hg. Patients were assigned randomly to one of two equal groups. The control group received saline, whereas the treatment group (TP group) received an initial bolus dose of terlipressin (1 mg over 30 mins) followed immediately by a continuous infusion of 2 μg·kg(-1)·h(-1) for 48 hrs. Portal pressure and gas exchange (radial artery, portal vein, and hepatic vein, blood gas analyses, and lactate concentration) were assessed at baseline (after ligation of the hepatic artery) and 2 hrs after drug administration. Systemic hemodynamic data and calculated tissue oxygenation parameters were compared throughout the procedure. Renal function was assessed by measurement of serum cystatin C after induction of anesthesia and on the first 2 days postoperatively. After the infusion of terlipressin, portal venous pressure decreased significantly from 26.3 ± 3.3 to 21.3 ± 3.6 mm Hg (p Portal and hepatic base excess, and the level of serum lactate, did not differ between the two groups. The serum levels of both cystatin C and creatinine were significantly higher in the control group than in the TP group on postoperative day 2. Perioperative use of terlipressin abrogates the early postoperative decline in renal function of patients who have chronic liver disease and undergo liver transplantation without any detrimental effect on hepatosplanchnic gas exchange and lactate metabolism.

  6. Renal transplantation in developing countries.

    Akoh, Jacob A


    Patients with established renal failure, living in developing countries, face many obstacles including lack of access to transplantation centers, quality and safety issues, and exploittation associated with transplant tourism. This review aims to determine the state and outcome of renal transplantation performed in developing countries and to recommend some solutions. The lack of suitable legislation and infrastructure has prevented growth of deceased donor programs; so, living donors have continued to be the major source of transplantable kidneys. Transplant tourism and commercial kidney transplants are associated with a high incidence of surgical complications, acute rejection and invasive infection, which cause major morbidity and mortality. Developing transplant services worldwide has many benefits - improving the results of transplantation as they would be performed legally, increasing the donor pool, making transplant tourism unnecessary and granting various governments the moral courage to fight unacceptable practices. A private-public partnership underpinned by transparency, public audit and accountability is a prerequisite for effective transplant services in the developing world. Finally, lack of dialysis facilities coupled with better outcomes in patients spending <6 months on dialysis prior to transplantation favor pre-emptive transplantation in developing countries.

  8. [Challenges in renal transplantation].

    Thuret, R; Kleinclauss, F; Terrier, N; Karam, G; Timsit, M O


    To describe kidney transplantation surgical techniques and to propose strategies in high-risk recipients. Relevant publications were identified through Medline ( and Embase ( database using the following keywords, alone or in association, "renal transplantation; peripheral arterial disease; obesity; third and fourth transplantation; robotic-assisted kidney transplant; anticoagulant therapy; dual kidney transplant". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and case-reports were selected. A total of 1949 articles were analyzed for arterial disease and anticoagulant therapy, 1083 for obesity, 663 for dual kidney transplants, 458 for third and subsequent procedures and 84 for robotic-assisted kidney transplantation. After careful selection, 304 publications were eligible for our review. Surgical assessment of future recipients is a pivotal step to anticipate technical difficulties, to interrupt clopidogrel or direct oral anticoagulants and to propose a revascularization procedure when necessary. Lack of data regarding obese recipients does not allow us to conclude about best surgical care or optimal timing but suggest that an early global management of obesity in chronic kidney disease patients is mandatory to improve access to a successful transplantation. In neurologic bladder and congenital anomalies, urodynamics and bladder function must be assessed prior to the onset of oliguria to intend an early treatment. Urinary diversion may be performed prior to or after transplantation with similar survival outcome and comparable rates of infections. Because of a rigorous selection of donors, the French dual kidney transplant program provides satisfactory outcomes, but fails in convincing surgical

  9. Dyslipoproteinemia in renal transplantation.

    Gunjotikar R


    Full Text Available Twenty-seven live related donor renal allograft recipients were evaluated for dyslipoproteinemia. Twenty-two patients received dual immunosuppression with prednisolone and azathioprine. Five patients received cyclosporin as well. Total cholesterol (Tch, triglycerides (TG, HDL cholesterol (HDLch, LDL cholesterol (LDLch and VLDL cholesterol (VLDLch levels were estimated. Fifteen (56% patients showed significant lipoprotein abnormalities. Renal allograft recipients showed significantly lower levels of Tch (p < 0.05 and LDLch (p < 0.05 and higher levels of TG (p < 0.005 and HDLch (p < 0.05. Diet and beta blockers did not influence lipoprotein levels. A significant negative correlation was noted between post-transplant duration and Tch, TG and VLDLch levels. Increased TG levels were associated with increase in weight and higher daily prednisolone dosage at the time of evaluation. The study confirms the existence of dyslipoproteinemia in renal allograft recipients.

  10. Impact of de novo donor-specific HLA antibodies detected by Luminex solid-phase assay after transplantation in a group of 88 consecutive living-donor renal transplantations.

    Dieplinger, Georg; Ditt, Vanessa; Arns, Wolfgang; Huppertz, Andrea; Kisner, Tuelay; Hellmich, Martin; Bauerfeind, Ursula; Stippel, Dirk L


    De novo donor-specific HLA antibodies (DSA) after renal transplantation are known to be correlated with poor graft outcome and the development of acute and chronic rejection. Currently, data for the influence of de novo DSA in patient cohorts including only living-donor renal transplantations (LDRT) are limited. A consecutive cohort of 88 LDRT was tested for the occurrence of de novo DSA by utilizing the highly sensitive Luminex solid-phase assay for antibody detection. Data were analyzed for risk factors for de novo DSA development and correlated with acute rejection (AR) and graft function. Patients with de novo DSA [31 (35%)] showed a trend for inferior graft function [mean creatinine change (mg/dL/year) after the first year: 0.15 DSA (+) vs. 0.02 DSA (-) (P = 0.10)] and a higher rate of AR episodes, especially in case of de novo DSA of both class I and II [6 (55%), (P = 0.05)]. Antibody-mediated rejection (AMR) appeared in five patients and was significantly correlated with de novo DSA (P = 0.05). Monitoring for de novo DSA after LDRT may help to identify patients at risk of declining renal function. Especially patients with simultaneous presence of de novo DSA class I and class II are at a high risk to suffer AR episodes.

  11. Heart transplantation from older donors

    V. N. Poptsov


    Full Text Available In the current situation of the shortage of suitable donor organs, heart transplantation from older donors is one of the ways to increase the performance of more heart transplants, particularly, in patients with urgent need of transplantation. While planning a heart transplantation from older donor one should consider increased risk of early cardiac allograft dysfunction, preexisting coronary artery disease, accelerated transplant vasculopathy which may adversely affect early and long-term survival of recipients. Subject to careful selection of donor–recipient pairs, effective prevention and treatment of early cardiac allograft dysfunction, pre-existing atherosclerosis and transplant vasculopathy the early and long-term survival of heart transplant recipients from older donors is comparable to heart transplantation from young donors.

  12. The impact of pretransplant donor-specific antibodies on graft outcome in renal transplantation: a six-year follow-up study

    Elias David-Neto


    Full Text Available OBJECTIVE: The significance of pretransplant, donor-specific antibodies on long-term patient outcomes is a subject of debate. This study evaluated the impact and the presence or absence of donor-specific antibodies after kidney transplantation on short- and long-term graft outcomes. METHODS: We analyzed the frequency and dynamics of pretransplant donor-specific antibodies following renal transplantation from a randomized trial that was conducted from 2002 to 2004 and correlated these findings with patient outcomes through 2009. Transplants were performed against a complement-dependent T- and B-negative crossmatch. Pre- and posttransplant sera were available from 94 of the 118 patients (80%. Antibodies were detected using a solid-phase (LuminexH, single-bead assay, and all tests were performed simultaneously. RESULTS: Sixteen patients exhibited pretransplant donor-specific antibodies, but only 3 of these patients (19% developed antibody-mediated rejection and 2 of them experienced early graft losses. Excluding these 2 losses, 6 of 14 patients exhibited donor-specific antibodies at the final follow-up exam, whereas 8 of these patients (57% exhibited complete clearance of the donor-specific antibodies. Five other patients developed ''de novo'' posttransplant donor-specific antibodies. Death-censored graft survival was similar in patients with pretransplant donor-specific and non-donor-specific antibodies after a mean follow-up period of 70 months. CONCLUSION: Pretransplant donor-specific antibodies with a negative complement-dependent cytotoxicity crossmatch are associated with a risk for the development of antibody-mediated rejection, although survival rates are similar when patients transpose the first months after receiving the graft. Our data also suggest that early posttransplant donor-specific antibody monitoring should increase knowledge of antibody dynamics and their impact on long-term graft outcome.

  13. The experiences of adults who are on dialysis and waiting for a renal transplant from a deceased donor: a systematic review.

    Burns, Tania; Fernandez, Ritin; Stephens, Moira


    Kidney transplantation has been recognized as the best renal replacement therapy option for people with end stage renal disease. With an estimated 170,000 people waiting for a kidney transplant around the world and a limited supply of donor organs, the waiting time is often prolonged for many years. The aim of this review was to examine the existing evidence of patients' experiences of living on dialysis and waiting for a renal transplant from a deceased donor. This review considered studies that included adult patients aged 18 years and over who had been on dialysis (hemodialysis or peritoneal dialysis) for up to 15 years and who were waiting for a renal transplant from a deceased donor. Types of intervention(s)/phenomena of interest: The phenomena of interest were the experiences of adults waiting for a renal transplant from a deceased donor and more specifically, the impact of waiting on their lifestyle and day to day living. Types of studies: This review considered studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research. Types of outcomes: This review considered studies that included the experiences of people who were waiting on dialysis for a kidney transplant from a deceased donor. The search strategy aimed to find both published and unpublished studies through electronic databases, reference list searches and the World Wide Web. Extensive searches were undertaken of the CINAHL, Embase, Medline and PsychInfo databases of published literature, the Cochrane Database of Systematic Reviews and the Virginia Henderson International Nursing Library, OpenGrey and the New York Academy of Medicine databases of unpublished literature. Each study was assessed for methodological quality by two independent reviewers using the Joanna Briggs Institute Qualitative Assessment and Review Instrument checklist. Disagreements between the reviewers were resolved

    Canossi, A; Del Beato, T; Piazza, A; Liberatore, G; Ozzella, G; Tessitore, A; Adorno, D


    This report describes the unknown exon 4 sequence of the rare A*7403 allele, identified in a Caucasian renal transplant cadaveric donor from Italy. This sequence is identical to that of the only known A*7401 exon 4, and this result allowed us to confirm the hypothesis of the generation of A*7403 allele from the ancestor A*7402 by point mutation in exon 2.

  15. Trasplante renal Kidney transplant

    P. Martín


    Full Text Available El trasplante renal es la terapia de elección para la mayoría de las causas de insuficiencia renal crónica terminal porque mejora la calidad de vida y la supervivencia frente a la diálisis. El trasplante renal de donante vivo es una excelente alternativa para el paciente joven en situación de prediálisis porque ofrece mejores resultados. El tratamiento inmunosupresor debe ser individualizado buscando la sinergia inmunosupresora y el mejor perfil de seguridad, y debe adaptarse a las diferentes etapas del trasplante renal. En el seguimiento del trasplante renal hay que tener muy en cuenta los factores de riesgo cardiovascular y los tumores puesto que la muerte del paciente con injerto funcionante es la segunda causa de pérdida del injerto tras el primer año del trasplante. La función alterada del injerto es un factor de mortalidad cardiovascular independiente que requerirá seguimiento y control de todas sus complicaciones para retrasar la entrada en diálisis.The kidney transplant is the therapy of choice for the majority of the causes of chronic terminal kidney insufficiency, because it improves the quality of life and survival in comparison with dialysis. A kidney transplant from a live donor is an excellent alternative for the young patient in a state of pre-dialysis because it offers the best results. Immunosuppressive treatment must be individualised, seeking immunosuppressive synergy and the best safety profile, and must be adapted to the different stages of the kidney transplant. In the follow-up to the kidney transplant, cardiovascular risk factors and tumours must be especially taken into account, given that the death of the patient with a working graft is the second cause of loss of the graft following the first year of the transplant. The altered function of the graft is a factor of independent cardiovascular mortality that will require follow-up and the control of all its complications to postpone the entrance in dialysis.

  16. Impact of immunosuppression treatment on the improvement in graft survival after deceased donor renal transplantation: a long-term cohort study.

    González-Molina, Miguel; Burgos, Dolores; Cabello, Mercedes; Ruiz-Esteban, Pedro; Rodríguez, Manuel A; Gutiérrez, Cristina; López, Verónica; Baena, Víctor; Hernández, Domingo


    We analyzed graft half-life and attrition rates in 1045 adult deceased donor kidney transplants from 1986-2001, with follow-up to 2011, grouped in two periods (1986-95 vs. 1996-01) according to immunosuppression. The Kaplan-Meier curve showed a significant increase in graft survival during 1996-2001. The uncensored real graft half-life was 10.25 years in 1986-95 and the actuarial was 14.58 years in 1996-2001 (P<0.001). The attrition rates showed a significantly greater graft loss in 1986-95, even excluding the first year from the analysis. The decline in renal function was significantly less pronounced in 1996-2001, indicating better preservation of renal function, despite the increase in donor age and stroke as the cause of donor death. The parsimonious Cox multivariate model showed donor age, acute rejection, panel reactive antibody, cold ischemia time and delayed graft function were significantly associated with a higher risk of graft loss. In contrast, the risk of graft loss fell by 21% in 1996-2001 compared with 1986-95. A similar reduction (25%) was observed when MMF treatment was entered into the multivariate model instead of study period. Long-term graft survival improved significantly in 1996-2001 compared to 1986-1995 despite older donor age. Modern immunosuppression could have contributed to the improved kidney transplant outcome.

    Full Text Available El objetivo del estudio fue comprender el significado de espera del trasplante renal para las mujeres en hemodiálisis. Se trata de un estudio cualitativo-interpretativo, realizado con 12 mujeres en hemodiálisis en Florianópolis. Los datos fueron recolectados a través de entrevistas en profundidad en el domicilio. Fue utilizado el software Etnografh 6.0 para la pre-codificación y posterior al análisis interpretativo emergieron dos categorías: “las sombras del momento actual”, que mostró que las dificultades iniciales de la enfermedad están presentes, pero las mujeres pueden hacer frente mejor a la enfermedad y el tratamiento. La segunda categoría, “la luz del trasplante renal”, muestra la esperanza impulsada por la entrada en la lista de espera para un trasplante.

  18. Postoperative comparison of result of renal transplantation between ethnic minorities and Han recipients after receiving kidneys from Han donors

    Han-wen CUI


    Full Text Available Objective  To analyze the outcomes and postoperative complications of renal transplant recipients of ethnic minorities and Han population in China, and investigate the differences between them. Methods  Clinical data from 89 minorit y patients and 100 Han patients who had received renal transplant of Hans' donators in Organ Transplantation Center of PLA from 1990 to 2012 were retrospectively analyzed. The general data before transplantation, and rate of short-term survival of the graft, incidence of delayed graft function (DGF, acute rejection, and pulmonary infection after transplantation were analyzed and compared. Results  No statistical difference was found in the preoperative personal profile between the recipients of minorities and Han nationality. In the recipients of minorities and Han nationality, the 1-year graft survival rate was 89.9% and 92%, the respective incidence of DGF was 28.1% and 27.0%, and the respective incidence of acute rejection was 22.5% and 19.0%, and there was no significant difference between them (P>0.05. The incidence of pulmonary infection was higher in minority recipients (30.3% than in Han recipients (10.0%, P0.05. Conclusion  The short-term clinical outcome of renal transplant recipients seems to be similar in different Chinese ethnic groups, but the incidence of pulmonary infection is higher in minority recipients, so it is important to strengthen monitoring in early postoperative period.

  19. Pre-transplant CDKN2A expression in kidney biopsies predicts renal function and is a future component of donor scoring criteria.

    Marc Gingell-Littlejohn

    Full Text Available CDKN2A is a proven and validated biomarker of ageing which acts as an off switch for cell proliferation. We have demonstrated previously that CDKN2A is the most robust and the strongest pre-transplant predictor of post-transplant serum creatinine when compared to "Gold Standard" clinical factors, such as cold ischaemic time and donor chronological age. This report shows that CDKN2A is better than telomere length, the most celebrated biomarker of ageing, as a predictor of post-transplant renal function. It also shows that CDKN2A is as strong a determinant of post-transplant organ function when compared to extended criteria (ECD kidneys. A multivariate analysis model was able to predict up to 27.1% of eGFR at one year post-transplant (p = 0.008. Significantly, CDKN2A was also able to strongly predict delayed graft function. A pre-transplant donor risk classification system based on CDKN2A and ECD criteria is shown to be feasible and commendable for implementation in the near future.

  20. Donor dopamine treatment in brain dead rats is associated with an improvement in renal function early after transplantation and a reduction in renal inflammation

    Hoeger, Simone; Reisenbuechler, Anke; Gottmann, Uwe; Doyon, Fabian; Braun, Claude; Kaya, Ziya; Seelen, Marc A.; van Son, Willem J.; Waldherr, Ruediger; Schnuelle, Peter; Yard, Benito A.


    Brain death (BD) is associated with tissue inflammation. As dopamine treatment of BD donor rats reduces renal monocyte infiltration, we tested if this treatment affects renal function and inflammation in recipients. BD was induced in F344 rats and was maintained for 6 h in all experiments. Dopamine

  1. Transpondo limites com doadores falecidos: transplantes bem-sucedidos com rins de doador com creatinina sérica igual a 13,1 mg/dL Overcoming limits with deceased donors: successful renal transplantations from a donor with serum creatinine of 13.1 mg/dL

    Rodrigo Klein


    Full Text Available Doadores falecidos não limítrofes com insuficiência renal aguda podem ser uma opção segura para aumentar a oferta de rins para transplante. A avaliação histológica é fundamental para o estabelecimento do prognóstico funcional desses enxertos. Dois transplantes renais foram realizados com rins provenientes de um doador falecido jovem com insuficiência renal aguda severa sem comprometimento estrutural do parênquima renal. Ambos os enxertos apresentaram atraso de funcionamento no período pós-operatório, embora um deles com boa diurese inicial não tenha necessitado diálise. Função renal adequada foi observada a partir do 30º dia após o transplante. A insuficiência renal aguda severa no doador falecido não é fator de risco independente para a evolução em curto prazo do enxerto renal e não deve ser considerada contra-indicação absoluta para a realização do transplante.Non-expanded deceased donors with acute kidney failure can be a safe option to increase the number of kidneys for transplantation. Histological evaluation is fundamental to establish the functional prognosis of those grafts. Two kidney transplantations were performed from a young deceased donor with severe acute kidney failure and no structural change in the renal parenchyma. Both patients had postoperative delayed graft function, but one of them, who had good initial urinary volume, required no dialysis. Adequate renal function was present at day 30 after transplantation. Severe acute kidney failure in deceased donors is not an independent risk factor for short-term outcome of renal graft and should not be considered an absolute contraindication for transplantation.

  2. Risk factors for delayed graft function in cadaveric kidney transplantation - A prospective study of renal function and graft survival after preservation with University of Wisconsin solution in multi-organ donors

    Koning, OHJ; Ploeg, RJ; VanBockel, JH; VanderWoude, FJ; Persijn, GG; Hermans, J


    Background. Delayed graft function (DGF) remains an important complication in renal transplantation. In this multicenter study, we investigated the influence of donor and recipient factors on the occurrence of DGF and DGF's effect on long-term graft survival. Methods. A total of 547 transplanted kid

  3. A four-drug combination therapy consisting of low-dose tacrolimus, low-dose mycophenolate mofetil, corticosteroids, and mizoribine in living donor renal transplantation: A randomized study

    Tian-zhong Yan


    Full Text Available Objective: We compared a three-drug combination therapy (control group consisting of tacrolimus, mycophenolate mofetil, and corticosteroids in living donor renal transplantation with a four-drug combination therapy (study group, in which the doses of tacrolimus and mycophenolate mofetil were halved and the immunosuppressive drug mizoribine was added, in order to determine whether the incidence rates of acute rejection after transplantation between the study group and the control group are similar, whether the study group regimen prevents the occurrence of calcineurin inhibitor–induced renal damage, and whether the study group regimen prevents adverse effects such as diarrhea caused by mycophenolate mofetil. Methods: We investigated the incidence of acute rejection, serum creatinine levels, and estimated glomerular filtration rate and the incidence of adverse effects such as diarrhea. Results: There was no significant difference between the two groups in the incidence of acute rejection. Renal function (estimated glomerular filtration rate and serum creatinine was maintained in the control group whereas in the study group renal function gradually improved, with a statistical difference observed at 12 months. The incidence of gastrointestinal symptoms including diarrhea was significantly higher in the control group than in the study group. There was no significant difference in the incidence of cytomegalovirus infection and other adverse effects. Conclusion: These results suggest the study group therapy is an effective regimen in preventing acute rejection and the deterioration of renal function. These results also show this therapy can reduce the incidence of adverse effects such as gastrointestinal symptoms.

  4. Pre-transplant infusion of donor-derived dendritic cells maintained at the immature stage by sinomenine increases splenic Foxp3(+) Tregs in recipient rats after renal allotransplantation.

    Li, Lian; Luo, Zhigang; Song, Zhe; Zheng, Liwen; Chen, Tuo


    The immunosuppressive mechanism of sinomenine in organ allotransplantation was investigated, especially its effect of blocking dendritic cell (DC) maturation, which might influence the frequency of regulatory T cells (Tregs). Bone marrow cells from male donor Wistar rats were induced to differentiate into DCs in vitro in the presence or absence of sinomenine, and characterized by flow cytometry. These two groups of DCs were respectively injected into male recipient Sprague-Dawley rats via the tail vein, at both high and low doses. Sprague-Dawley rats receiving saline injection were used as controls. Seven days later, renal transplantation was performed from donor Wistar rats to the recipient Sprague-Dawley rats. Seven days after transplantation, spleens were collected from the recipients. The proportions of Tregs and Foxp3(+) Tregs to CD4(+) T cells were determined using flow cytometry. With sinomenine treatment, the frequency of mature DCs was reduced, as indicated by lower expression of the surface markers CD80, CD86, and RT1B. In recipient Sprague-Dawley rats that received sinomenine-treated DCs before renal allotransplantation, the proportions of splenic Tregs and Foxp3(+) Tregs were significantly higher than in control recipients receiving saline or DCs without sinomenine treatment (all pincreasing Tregs than the low dose (10(5) cells) (pincrease of Foxp3(+) Tregs in the spleens of recipients after renal allotransplantation.

  5. Donor-specific anti-HLA antibodies after bone-graft transplantation. Impact on a subsequent renal transplantation: a case report.

    Mosconi, G; Baraldi, O; Fantinati, C; Panicali, L; Veronesi, M; Cappuccilli, M L; Corsini, S; Zanelli, P; Bassi, A; Buscaroli, A; Feliciangeli, G; Stefoni, S


    Immunological evaluation by panel-reactive antibody (PRA) and determination of anti-HLA specificity are important phases in the evaluation of patients awaiting kidney transplantation. The main causes of immunization are previous solid organ transplantation, hemotransfusion, and pregnancy. It is also possible that immunogenicity can be triggered by vascularized tissue grafts. Immune induction by cryopreserved bone prostheses is not yet understood. A 19-year-old patient with osteosarcoma had undergone resection of the left proximal tibia with reconstruction using human bone in 1997. The donor HLA typing was as follows: A3, A29 (19); B44 (12), Bw4; DR13 (6), DR7, DR52, DR53. The patient was subsequently enrolled onto the waiting list for cadaveric donor kidney transplantation due to chronic kidney failure caused by cisplatin toxicity. Pretransplantation immunological screening using the complement-dependent cytotoxicity (CDC) technique revealed a PRA of 63%. IgG antibody specificities were detected against class I and class II donor antigens, specifically anti-A3, B44, DR7 antibodies, using flow cytometry (Tepnel Luminex). Further immunological studies using single HLA specificity analysis (LSA Class I degrees -II degrees , Tepnel-Luminex) showed direct antibodies against all donor antigen specificities. This case showed immune induction after the implantation of bone prosthesis in a kidney transplant candidate, underlining the importance of the availability of HLA typing data of donors of a human prosthesis.

  6. Incidental solid renal mass in a cadaveric donor kidney

    R M Meyyappan


    Full Text Available The number of patients living with end-stage renal disease (ESRD is increasing in our country and demand for renal grafts is ever increasing. Cadaver renal transplantation is being established as a viable supplement to live transplantation. We present a case where a mass lesion was encountered in the donor kidney from a cadaver. Enucleation of the lesion was done and we proceeded with the grafting. Histopathological examination showed a ′Renomedullary interstitial cell tumour′, a rare benign lesion. Post transplant, the renal function recovered well and the patient is asymptomatic. Such incidental renal masses present an ethical dilemma to the operating surgeon.

  7. [Renal transplantation without maintenance immunosuppression. Identical twins and kidney transplantation following a successful bone marrow graft].

    Hadi, Riad Abdel; Thomé, Gustavo Gomes; Ribeiro, Adriana Reginato; Manfro, Roberto Ceratti


    Renal transplantation without maintenance immunosuppression has been sporadically reported in the literature. The cases include non-adherent patients who discontinued their immunosuppressive medications, transplantation between identical twins, kidney transplantation after a successful bone marrow graft from the same donor and simultaneous bone marrow and kidney transplantation for the treatment of multiple myeloma with associated renal failure. There are also ongoing clinical trials designed to induce donor specific transplant tolerance with infusion of hematopoietic cells from the same kidney donor. Here we describe two cases of renal transplantation without immunosuppression as examples of situations described above.

  8. Left versus right deceased donor renal allograft outcome.

    Phelan, Paul J


    It has been suggested that the left kidney is easier to transplant than the right kidney because of the longer length of the left renal vein, facilitating the formation of the venous anastomosis. There are conflicting reports of differing renal allograft outcomes based on the side of donor kidney transplanted (left or right).We sought to determine the effect of side of donor kidney on early and late allograft outcome in our renal transplant population. We performed a retrospective analysis of transplanted left-right deceased donor kidney pairs in Ireland between January 1, 1998 and December 31, 2008. We used a time to death-censored graft failure approach for long-term allograft survival and also examined serum creatinine at different time points post-transplantation. All outcomes were included from day of transplant onwards. A total of 646 transplants were performed from 323 donors. The incidence of delayed graft function was 16.1% in both groups and there was no significant difference in acute rejection episodes or serum creatinine from 1 month to 8 years post-transplantation.There were 47 death-censored allograft failures in the left-sided group compared to 57 in the right-sided group (P = 0.24). These observations show no difference in renal transplant outcome between the recipients of left- and right-sided deceased donor kidneys.

  9. Two successful lung transplantations from a dialysis-dependent donor.

    Shlomi, Dekel; Shitrit, David; Bendayan, Daniele; Sahar, Gidon; Saute, Milton; Kramer, Mordechai R


    The shortage of organs for lung transplantation has led to the growing use of "marginal" donors. Although patients on hemodialysis are still excluded as lung transplant donors because of the possible effects of renal failure on the lungs, recent data suggest that they may be suitable in selected cases. This article describes the successful transplantation of two lungs from a single donor who had been receiving long-term hemodialysis treatment. In the absence of other causes of pulmonary diseases, such as smoking or lung infection, lungs from dialysis-dependent patients may be acceptable for lung transplantation.


    A.A.Jr Rodrigues


    Full Text Available A grande procura de órgãos para transplante tornou necessária a aceitação de potenciais doadores pediátricos a fim de aumentar a oferta. Trabalhos anteriores relatando menor sobrevida do enxerto e taxas maiores de complicação fizeram com que cirurgiões considerassem o assunto com cautela. Esse é um estudo retrospectivo com o objetivo de analisar os resultados de transplantes renais em bloco de doadores infantis (The high demand for organs for transplantation has made it necessary to consider using the youngest of potential donors in order to increase the organ supply. Previous reports of decreased graft survival and increased complication rates have made surgeons wary of using such kidneys. This is a chart review with the objective to analyse the results achieved with transplantation of children kidneys (< 2 years in the HCFMRP-USP from 1998 to 2000. A total of 5 pacients received en bloc renal transplants from donors aged 9 months to 2 years old, weighthing between 8 and 14 kg. Results: Only one patient lost the allograft within 8 days of transplantation due to allograft trombosis. Two patients had ureteral complications, one with ureteral necrosis and urinary fistula and the other with total ureterovesical anastomosis disrupture. Both were successfully repaired. Intra operatory complication was experienced in one pacient, with arterial anastomosis rupture. In loco reperfusion and repair was made. Another patient had inferior renal pole rupture, treated with polar nefrectomy at the 4º PO. Despite such problems, mean follow up of 20,7 months showed serum creatinine ranging from 0,9 to 2 mg/100ml, with no serious complications. Conclusion: Our data support the use of en bloc child cadaveric kidneys, even from infant donors less than two year of age, when the organ necessity supplant the higher rates of complications.

  11. Clinical and anti-HLA antibody profile of nine renal transplant recipients with failed grafts: donor-specific and non-donor-specific antibody development.

    Rebellato, Lorita M; Ozawa, Miyuki; Verbanac, Kathryn M; Catrou, Paul; Haisch, Carl E; Terasaki, Paul I


    predictor of late graft loss via chronic allograft nephropathy, understanding and modifying the antibody response is critical to extending the longevity of transplanted organs. Finally, since the strong sensitization to NDSA will seriously hamper the ability to identify a compatible donor for a future transplant, these data reinforce the importance of minimizing HLA mismatches between the donor and the recipient.

  12. [The kidney transplantation from the ABO-incompatible donors].

    Goriaĭnov, V A; Kaabak, M M; Babenko, N N; Shishlo, L A; Morozova, M M; Ragimov, A A; Dashkova, N G; Salimov, É L


    The experience of 28 allotransplantations of ABO-incompatible kidneys was compared with the treatment results of 38 ABO-compatible renal transplantations. The transplanted kidney function, morphological changes of the transplanted kidney and the comparative analysis of actuary survival in both groups showed no significant difference. The results of the study prove the validity of the kidney transplantation from the ABO-incompatible donors.

  13. Obesity and urologic complications after renal transplantation

    Ashkan Heshmatzadeh Behzadi


    Full Text Available Although obesity has been associated with improved survival on dialysis, its short-and long-term effects on renal transplantation outcomes remain unclear. Herein, we evaluate the short-term and intermediate long-term effects of obesity on first-time renal transplant patients. A retrospective analysis was performed on 180 consecutive renal transplant recipients from living unrelated donors during 2006-2008 in a major transplantation center in Tehran, Iran. Among these, 34 (18% patients were found to be obese (body mass index ≥30 kg/m 2 . Obese patients were more likely to develop post-transplant renal artery stenosis (RAS (17.6% vs. 2.8%, P <0.001, hematoma (47.9% vs. 17.6, P = 0.009, surgical wound complications (64.7% vs. 9.6%, P <0.001 and renal vein thrombosis (2% vs. 0%, P <0.001. However, the incidence of delayed graft function, lymphocele, urologic complications of ureterovesical junction stenosis or urinary leakage, surgical complications of excessive bleeding or renal artery thrombosis and duration of hospitalization were similar between the two groups. The two-year patient and graft survival were also statistically not different. Renal transplantation in obese recipients is associated with a higher incidence of post-transplant RAS, hematoma, surgical wound complications and renal vein thrombosis, but similar two-year patient and graft survival.

  14. Pregnancy and renal transplantation.

    Başaran, O; Emiroğlu, R; Seçme, S; Moray, G; Haberal, M


    Ovarian dysfunction, anovulatory vaginal bleeding, amenorrhea, high prolactin levels, and loss of libido are the causes of infertility in women with chronic renal failure. After renal transplantation, endocrine function generally improves after recovery of renal function. In this study we retrospectively evaluated the prepregnancy and postdelivery renal function, outcome of gestation, as well as maternal and fetal complications for eight pregnancies in eight renal transplant recipients between November 1975 and March 2003 of 1095 among 1425. Eight planned pregnancies occurred at a mean of 3.6 years posttransplant. Spontaneous abortion occured in the first trimester in one case. One intrauterine growth retardation was observed with a full-term pregnancy; one intrauterine growth retardation and preterm delivery; one preeclampsia with preterm delivery and urinary tract infection; and one preeclampsia with preterm delivery and oligohydramnios. The mean gestation period was 35.5 +/- 3.0 weeks (31.2 to 38.0). Pregnancy had no negative impact on renal function during a 2-year follow-up. No significant proteinuria or acute rejection episodes were observed. Among the seven deliveries, no congenital anomaly was documented and no postpartum problems for the child and the mother were observed. Our study suggests that successful pregnancy is possible in renal transplant recipients. In cases with good graft function and absence of severe proteinuria or hypertension, pregnancy does not affect graft function or patient survival; however, fetal problems are encountered such as intrauterine growth retardation, low birth weight, and preeclampsia.

  15. Pediatric renal transplantation: Jordan′s experience

    Issa Hazza


    Full Text Available To evaluate our experience with pediatric renal transplantation at King Hussein Medical Center, the medical records of 71 pediatric patients who underwent a renal transplantation procedure between the years 2004 and 2010 or started follow-up at our center within one week of transplantation done elsewhere were reviewed. Over the seven-year period, 71 children under the age of 14 years who received their first renal transplant were studied. About 56% (40 were males. The mean age was 9.44 ± 2.86 years. Dysplastic kidney was the most common cause of end-stage renal failure in our group, followed by glomerulonephritis. Mothers were the donors in 39.4% of the cases, followed by fathers. Twenty-three patients (32.4% were transplanted preemptively. The overall one-year graft survival was 96%, three-year survival was 95%, and the five-year survival was 88%. Prednisone, tacrolimus, and mycophenolate mofetil formed the main-stay of immunosuppressive agents. We have developed a successful live donor program for renal transplantation in children at King Hussein Medical Center in Amman. Although our experience is still short, the graft survival is similar to that achieved in the developed world, especially with preemptive transplant.

  16. Renal transplantation in Mapuche people.

    Ardiles, R; Beltrán, R; Jerez, V; Droguett, M A; Mezzano, S; Ardiles, L


    Previous studies have demonstrated higher concentrations of some histocompatibility antigens in Mapuche people compared with non-Mapuche Chileans in the renal transplantation program. With the aim of evaluating whether those antigenic differences might induce differences in the outcomes of renal transplantation among patients belonging to that ethnic group, we reviewed HLA studies and at least 6 months follow-up of all patients with a first kidney transplant between 1980 and 2006. The 248 patients had a mean age of 37.6 years, 40% were females, and 48% had living related donors. The mean kidney follow-up was 90 months and patient follow-up was 106 months. Thirty-nine patients (16%) were classified as Mapuche, according to their surnames, including 16 women with overall mean age of 34.5 years, and 14 had been transplanted from a living related donor. Mapuche patients received organs with better HLA matching expressed as number of identities (3.4 +/- 0.1 versus 2.8 +/- 0.1 among non-Mapuche; P or = 3 compatibilities was significantly higher (Mapuche 38% versus non-Mapuche 22%; P Mapuche; and 83% and 65%, respectively, for non-Mapuche. Patient survival rates were 97% at 5 years and 86% at 10 years in the Mapuche group versus 91% and 79%, respectively, in the non-Mapuche group; both results were not significantly different. Our results showed similar outcomes of kidney and patient survivals among Mapuche people even when they received organs with better HLA matches.

  17. Sporotrichosis in Renal Transplant Patients

    Paulo Gewehr


    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

  18. [De novo tumours of renal transplants].

    Hétet, J F; Rigaud, J; Dorel-Le Théo, M; Láuté, F; Karam, G; Blanchet, P


    Kidney cancer occurs rarely and late in renal transplants. The lack of grafts and the increasing age of the cadaver donors are likely to result in an increasing number of such cancers. To date, the treatment of choice is the transplant removal. Nevertheless partial nephrectomy may be discussed in selected cases. Ultrasonographic screening should allow detection of low volume tumours suitable for partial nephrectomy. Alternative techniques (radiofrequency, cryoablation) are to be assessed in such patients.

  20. Paid Living-Unrelated Renal Transplantation Abroad: Too Much Unknown

    Yalçın SOLAK


    Full Text Available OBJECTIVE: Despite the unethical characteristic and unfavorable consequences, paid livingunrelated renal transplantation is still considered as an option for end-stage renal disease patients. This study aimed to compare the medical and surgical complications along with allograft functions of PLURT patients with age and gender matched transplant recipients who received a living or deceased donor kidney at our center. MATERIAL and METHODS: End-stage renal disease patients received PLURT (group 1 in a foreign country and age, and gender matched renal transplant recipients that received renal transplantation from living-related donors (LRT patients; group 2 and deceased donors (DDRT patients; group 3 followed between 2003-2010 at our transplantation center were included in the study. RESULTS: There were no significant differences between groups (Group 1&2 and group 1&3 regarding age, sex, urea, creatinine, creatinine clearance, and proteinuria. Data about patients that received renal transplantation from living-related and deceased-donors at our center were sufficient when compared with PLURT patients. PLURT has a negative impact on patients' survival because of surgical and medical problems. CONCLUSION: In the present study, PLURT, LRT and DDRT patients had early and late complications of renal transplantation which were similarly seen in recent studies. The main problem for unfavorable results of PLURT is the commercial aspect of renal transplantation without considering the risks for ESRD patients.

  1. Successful Pregnancies Post Renal Transplantation

    Alfi Adnan


    Full Text Available To evaluate the maternal and fetal outcomes in renal transplant female recipients who became pregnant from 1989 to 2005 in our center, we retrospectively studied 20 incident pregnancies in 12 renal transplant recipients; 5 (41.7 % of them from living related, 4 (33.3% from deceased, and 3 (25% from living unrelated donors. The mean age at pregnancy was 30.5 ± 4.5 years and mean interval from transplantation to pregnancy was 21 ± 5.7 months with the interval was < 1 year in one patient. The mean serum creatinine (SCr before pregnancy vs 6 months post delivery was 110 ± 24.3, and 156 ± 190 µmol/ L, respectively, (p = 0.2. All patients were normotensive during the prenatal period except two who were hypertensive, none was markedly proteinuric, and only one acute rejection episode occurred during one pregnancy. Graft loss one year post delivery occurred in 2 patients; one with elevated prenatal SCr > 132 µmol/L, and another with short interval from transplantation to pregnancy < 1 year, while the remaining 10 patients revealed current mean SCr of 105 ± 18.2 µmol/L. Complications during pregnancy inclu-ded pre-eclampsia in (25%, UTI (25%, preterm delivery < 37 weeks (30%, however, none of the pregnancies ended by abortion. Normal vaginal delivery vs cesarean section was 70% vs 30%, respectively. Gestational age at delivery was 36.3 ± 3.9 weeks, and mean fetal birth weight was 2349 ± 574 gm. Apgar score was 9-10 in all of the 20 babies, and none revealed intrauterine growth retardation or congenital anomalies. We conclude that consecutive pregnancies demons-trate long-term maternal and fetal survival and function. The major risk factors are elevated starting serum creatinine, hypertension, and short time interval from transplantation to pregnancy.

  2. [Living donor transplantation. Surgical complications].

    Karam, Georges


    Although nephrectomy by open surgery is the most used technique for the extraction of kidney transplants in the living donor, nephrectomy under laparaoscopy is increasingly practiced. Laparoscopic nephrectomy is less invasive and performed under videoscopy control, after insufflation of the peritoneal cavity. Three to four incisions are done in order to enter the surgical instruments. The kidney is extracted through a horizontal sus-pubic incision. The exposition is either exclusively transperitoneal, retroperitoneal or hand assisted. The advantages of laparoscopy are esthetical, financial due to a shorter hospitalisation and a quicker recovery, as well a confort for the donor. The disadvantages are a longer warm ischemia time and possibly a higher risk of delayed graft function. Randomised studies having compared laparoscopy and open surgery in the living donor have not find any significant difference regarding the per- and perioperative in the complications.

  3. Transplanting Kidneys from Deceased Donors With Severe Acute Kidney Injury.

    Heilman, R L; Smith, M L; Kurian, S M; Huskey, J; Batra, R K; Chakkera, H A; Katariya, N N; Khamash, H; Moss, A; Salomon, D R; Reddy, K S


    Our aim was to determine outcomes with transplanting kidneys from deceased donors with acute kidney injury, defined as a donor with terminal serum creatinine ≥2.0 mg/dL, or a donor requiring acute renal replacement therapy. We included all patients who received deceased donor kidney transplant from June 2004 to October 2013. There were 162 AKI donor transplant recipients (21% of deceased donor transplants): 139 in the standard criteria donor (SCD) and 23 in the expanded criteria donor (ECD) cohort. 71% of the AKI donors had stage 3 (severe AKI), based on acute kidney injury network (AKIN) staging. Protocol biopsies were done at 1, 4, and 12 months posttransplant. One and four month formalin-fixed paraffin embedded (FFPE) biopsies from 48 patients (24 AKI donors, 24 non-AKI) underwent global gene expression profiling using DNA microarrays (96 arrays). DGF was more common in the AKI group but eGFR, graft survival at 1 year and proportion with IF/TA>2 at 1 year were similar for the two groups. At 1 month, there were 898 differentially expressed genes in the AKI group (p-value kidneys from deceased donors with AKI is safe and has excellent outcomes.

  4. Living and cadaver donor transplant programs in the maghreb

    Jamil Hachicha


    Full Text Available In the Maghreb, organ failure constitutes a major public health problem, especially given the increasing number of patients with chronic renal failure and the high cost of care. In this study, we attempted to seek the recommendations, through a questionnaire, of various officials related to organ transplantation as well as leaders of ethics committees and religious groups in different countries of the Maghreb. The objective was to improve the rate of organ donation and transplantation. We received 36 replies (62% within the prescribed time limit. In our survey, 83% of the respondents felt that living donor transplantation should be promoted initially, followed gradually by measures to increase cadaver donor transplantation to achieve a target of about 30 transplants with cadaver kidney donors per million inhabitants. To expand the donor pool, 83% of the respondents proposed to expand the family circle to include the spouse and inlaws. To improve the cadaver donation activity, one should improve the organizational aspects to ensure at least 50 renal transplantations per year (100% and provide material motivation to the treatment team proportional to the activity of organ donation and transplantation. Finally, 93% of the respondents suggested suitable moral motivation of the donors.

    A stagnant supply of transplantable organs in the face of a relentless burgeoning of transplant waiting lists has created a crisis. Necessity continues to be the mother of invention and as the crisis has deepened it has served as a crucible for the development of new ways to think about perennial problems. Our program has taken a 2-pronged approach to increasing the organ supply for our patients. First, through innovations like the laparoscopic donor nephrectomy, ABO-incompatible and positive-crossmatch transplantation protocols, unconventional paired kidney exchanges, and the use of altruistic donors we have more than doubled our utilization of live donor organs. At the same time, we have developed algorithms and interrogative techniques to enhance the intelligent use of kidneys from expanded criteria donors for patients who do not have an available live donor. The laparoscopic nephrectomy has proven to be a safe and effective way of removing a significant barrier to live donation. Our results from 100 ABOi, (+)XM, and PKE transplants are similar to national statistics for compatible live donor transplants, suggesting that existing paradigms of compatibility can be safely expanded. These encouraging early outcomes and the savings they transmit to the health care system have allowed us to obtain insurance coverage for the InKTP programs, setting the stage for further expansion of these opportunities to broaden the options for patients with end-stage renal disease.

  6. [Pediatric renal transplantation in Toulouse (author's transl)].

    Juskiewenski, S; Barthe, P; Vaysse, P; Bouissou, F; Guitard, J; Bacque, P; Moscovivi, J; Cao-Van, C


    The regional group of renal transplantation in Toulouse includes a medico-surgical team which participates to all the activities of this group. Dialysis and transplantation are covered in a center organized for the care of children. This branch is part of the Regional Hospital. From 15 years old on patients are moved from the pediatric branch to the medico-surgical center taking care of adults. Both teams within the regional hospital share the responsability of taking off kidneys from cadaveric donors and collaborate to France-Transplant and Euro-Transplant. Since the pediatric center in charge of renal failure has opened, 32 children underwent chronic hemodialysis. Some of these patients are presently treated in the center for adults. Fourteen children were grafted and seven are at this moment waiting to receive transplantation. The average number of transplantations per year is from 1 to 4. These fourteen children underwent renal transplantation with kidneys from cadaveric donors. Only one has been provided by Toulouse. Diuresis resumed immediately in 8 cases, later in 5. An extremely acute reject was observed in one case and transplantectomy had to be performed 10 days after transplantation. Eight children presented acute reversible reject which, for 4 of them, evoluated towards chronicle reject. Eight children presented a chronicle reject: 4 of them are again in dialysis. Altogether 8 kidneys are functioning (seven years in the longest case). Five children resumed chronic dialysis. One patient died of acute pancreatitis. He underwent a portocaval shunt for type I glycogenosis which ended in a hyperuricemic nephropathy evoluating towards renal failure forcing a transplantation. The rehabilitation of transplanted children was always satisfactory.

  7. Effective use of kidneys for transplantation from asystolic donors.

    Gerstenkorn, Clemens; Papalois, Vassilios E; Hakim, Nadey


    Severe organ shortage for transplantation is an increasing problem because the number of traditional heart-beating cadaveric donors is declining. Ways need to be found to expand the donor pool without commercializing organ transplantation, especially from unrelated live donors, and to maintain high medical standards of these procedures and their follow-up. Kidneys from asystolic or nonheart-beating donors (NHBDs) are a valuable source of organs, which can be of excellent quality, with good long-term function after transplantation. This organ source is widely underused at the moment; even so, there is increased popularity during the last few years in different countries. In addition, the rate of discarding viable kidneys from these NHBDs is still too high. Logistical and legal aspects are other important issues that need to be addressed to promote these NHBD programs more effectively. Waiting lists for renal transplantation could be significantly reduced in the future.

  8. Effect of nifedipine on renal transplant rejection.

    Nicholson, M L; Dennis, M J; Beckingham, I J; Smith, S J


    The effect of early nifedipine therapy on acute renal allograft rejection was studied in 170 adult cadaveric transplant recipients. Acute rejection occurring in the first 3 months after transplantation was diagnosed by Tru-cut biopsy and the severity of each rejection episode assessed histologically. The incidence of acute rejection was significantly lower in patients treated with nifedipine (29 of 80; 36 per cent) than in controls (52 of 90; 58 per cent) (P nifedipine exerted a significant independent effect on the incidence of early acute rejection. Other factors identified in the multivariate model as influencing rejection were human leucocyte antigen (HLA) matching at the DR locus, blood level of cyclosporin during the first week, HLA matching at the B locus, donor age and donor sex. The 1-year graft survival rate was 88.6 per cent in patients given nifedipine and 63.8 per cent in controls (P nifedipine therapy has a useful role in human renal transplantation.

  9. Transplant tourism and the Iranian model of renal transplantation program: ethical considerations.

    Ghods, Ahad J; Nasrollahzadeh, Dariush


    Currently, the buying and selling of kidneys through "transplant tourism" is occurring at an increasing rate, both in developed and developing countries. Since 1988, Iran has adopted a compensated and regulated living-unrelated donor renal transplant program, and by providing financial incentives to volunteer living donors, has eliminated the renal transplant waiting list. In the Iranian model of renal transplantation program, regulations have been put in place to prevent transplant tourism. Foreigners are not allowed to undergo renal transplantation from Iranian living-unrelated donors. They also are not permitted to volunteer as kidney donors for Iranian patients. A study at the transplant unit of Hashemi Nejad Kidney Hospital in Tehran, Iran, showed that of 1881 renal transplant recipients, 19 (1%) were Afghani or Iraqi refugees, 11 (0.6%) were other foreign nationals, and 18 (0.9%) were Iranian immigrants. Renal transplantations seemed ethically acceptable to all refugees and foreign nationals. However, transplantation of Iranian immigrants who had been residing abroad for years constituted true transplant tourism.

  10. Renal allograft tuberculosis with infected lymphocele transmitted from the donor.

    Al-Nesf, Maryam Ali; Al-Ani, Omar Isam; Al-Ani, Ahmed Abdul-Rahman; Rashed, Awad Hamed


    Transmission of tuberculosis (TB) from a donor through renal transplantation is a rare incident. We are reporting a 53-year-old Qatari woman diagnosed with renal allograft TB infection. The disease was confirmed by isolation of Mycobacterium tuberculosis from fluid from the lymphocele and demonstration of caseating granuloma in graft biopsy with acid-fast bacilli seen on Ziehl-Neelsen staining. The diagnosis was made quite early post-transplantation. The presence of the granuloma, which is unusual with patients on intensive immunosuppressant medications, suggests that transmission of the infection occurred from the donor rather than from the activation of latent infection. In reviewing the literature, we found ten case reports of TB in transplanted kidney with transmission of TB infection from the donor. The presence of TB in lymphocele in association with the infected transplant by TB, to the best of our knowledge, was reported only once in the literature. Our case had unfavorable outcome and ended by renal allograft nephrectomy and hemodialysis. We are presenting this case of TB infection of renal allograft and lymphocele diagnosed early post-transplantation transmitted from the donor and pertinent review from the literature.

  11. Organ transplantation from deceased donors with cancer: is it safe?

    Nalesnik MA


    Full Text Available Michael A Nalesnik1, Michael G Ison21Division of Transplantation and Hepatic Pathology, Department of Pathology, University of Pittsburgh Medical Center, Pittsburg, PA, USA; 2Divisions of Infectious Diseases and Organ Transplantation, Northwestern University Feinberg School of Medicine, Chicago, IL, USAAbstract: The availability of donor organs continues to be insufficient to meet the needs of patients actively waiting for transplant. Consequently, there is continuing pressure to increase the donor organ pool while simultaneously assuring safety for the recipient population. The complication of donor malignancy transmission has been documented almost from the beginning of transplantation, and continues to be a concern today. The anecdotal nature of case reports and compiled series ensures that clinical decisions related to organ use from donors with malignancy will of necessity continue to be made on the basis of low-level evidence. Despite this limitation, the literature indicates that not all donor neoplasms have the same risk for transmission to the recipient, and it is necessary to consider the specific malignancy affecting the donor, as well as the condition of the recipient, before a decision is made to transplant or discard a given organ. Published cases suggest that certain forms of neoplasia, such as melanoma, choriocarcinoma, sarcoma, small cell carcinoma, or metastatic carcinomas serve as strong contraindications to organ donation. In contrast, considerable experience exists to suggest that certain tumors of the central nervous system, small subclinical prostate carcinomas, or small renal cell carcinomas resected prior to transplant, among other tumors, should not in themselves disqualify an individual from donating organs in the appropriate circumstance. This review presents the case for considering organ transplantation in the setting of certain donor malignancies and discusses factors to be weighed in such decisions. Additionally

  12. Preformed donor HLA-DP-specific antibodies mediate acute and chronic antibody-mediated rejection following renal transplantation.

    Jolly, E C; Key, T; Rasheed, H; Morgan, H; Butler, A; Pritchard, N; Taylor, C J; Clatworthy, M R


    Donor-specific HLA alloantibodies may cause acute and chronic antibody-mediated rejection (AMR) and significantly compromise allograft survival. The clinical relevance of antibodies directed against some HLA class II antigens, particularly HLA-DP, is less clear with conflicting reports on their pathogenicity. We report two patients with high levels of pretransplant donor-specific HLA-DP antibodies who subsequently developed recurrent acute AMR and graft failure. In both cases, there were no other donor-specific HLA alloantibodies, suggesting that the HLA-DP-specific antibodies may be directly pathogenic.

  13. [Multiple complications after renal transplantation].

    Manrique, J; Rossich, E; Hernández Sierra, A


    This is the case of a 32-year-old male patient, diagnosed with end stage renal disease secondary to a focal and segmental glomerulonephritis. After four years of haemodialysis, he received a renal graft from a cadaveric donor. During the following sixteen years, he developped many different complications. In the early post-transplant period, he developed a severe acute tubular necrosis and two episodes of acute rejection took place, both of them with later recovery. Among the outstanding infectious complications were a virus herpes zoster dorsal infection and a Pseudomonas aeruginosa nosocomial pneumonia. Twelve months later, a series of severe digestive complications took place: cholecystitis that required cholecystectomy, pancreatic pseudocyst which required laparotomy because of an abdominal complication, two separate episodes of upper digestive bleeding that finally required gastric surgery, and an hemorrhagic subphrenic abscess that required a second laparotomy. Currently he has developed a calcified chronic pancreatitis. Moreover, metabolic complications must be mentioned carbohydrate intolerance, cataracts and an avascular bone necrosis, all of them closely related to the immunosuppressive therapy. In spite of these multiple complications, he mantains a good renal function and his quality of life is acceptable.

  14. Kidney Transplantation From a Donor With Sickle Cell Disease.

    Rossidis, A; Lim, M A; Palmer, M; Levine, M H; Naji, A; Bloom, R D; Abt, P L


    In the United States, >100 000 patients are waiting for a kidney transplant. Given the paucity of organs available for transplant, expansion of eligibility criteria for deceased donation is of substantial interest. Sickle cell disease (SCD) is viewed as a contraindication to kidney donation, perhaps because SCD substantially alters renal structure and function and thus has the potential to adversely affect multiple physiological processes of the kidney. To our knowledge, transplantation from a donor with SCD has never been described in the literature. In this paper, we report the successful transplantation of two kidneys from a 37-year-old woman with SCD who died from an intracranial hemorrhage. Nearly 4 mo after transplant, both recipients are doing well and are off dialysis. The extent to which kidneys from donors with SCD can be safely transplanted with acceptable outcomes is unknown; however, this report should provide support for the careful expansion of kidneys from donors with SCD without evidence of renal dysfunction and with normal tissue architecture on preimplantation biopsies. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

  15. Haemostatic aspects of renal transplantation.

    Sørensen, P J; Schmidt, E B; Knudsen, F; Nielsen, A H; Kristensen, S D; Dyerberg, J; Kornerup, H J


    Platelet function and protein C activity and antigen level was studied in 31 renal transplant recipients and 10 healthy controls. The patients were divided into three groups: (I) cyclosporin treated, (II) azathioprine treated, and (III) azathioprine treated patients with chronic rejection. The platelet function in the renal transplant patients was normal and there was no difference between groups I and II. The specific activity of protein C was decreased in patients after renal transplantation and decreasing protein C activity and progressive renal failure was found to be positively correlated in the azathioprine treated groups.

  17. Donor-transmitted, donor-derived, and de novo cancer after liver transplant.

    Chapman, Jeremy R; Lynch, Stephen V


    Cancer is the third most common cause of death (after cardiovascular disease and infection) for patients who have a functioning kidney allograft. Kidney and liver transplant recipients have similar cancer risks because of immunosuppression but different risks because of differences in primary diseases that cause renal and hepatic failure and the inherent behavior of cancers in the liver. There are 4 types of cancer that may develop in liver allograft recipients: (1) recurrent cancer, (2) donor-transmitted cancer, (3) donor-derived cancer, and (4) de novo cancer. Identification of potential donor cancer transmission may occur at postmortem examination of a deceased donor or when a probable donor-transmitted cancer is identified in another recipient. Donor-transmitted cancer after liver transplant is rare in Australia, the United Kingdom, and the United States. Aging of the donor pool may increase the risk of subclinical cancer in donors. Liver transplant recipients have a greater risk of de novo cancer than the general population, and risk factors for de novo cancer in liver transplant recipients include primary sclerosing cholangitis, alcoholic liver disease, smoking, and increased age. Liver transplant recipients may benefit from cancer screening because they have a high risk, are clearly identifiable, and are under continuous medical supervision.

  18. Challenges in renal transplantation in Yemen.

    El-Nono, Ibrahiem H; Telha, Khaled A; Al-Alimy, Gamil M; Ghilan, Abdulilah M; Abu Asba, Nagieb W; Al-Zkri, Abdo M; Al-Adimi, Abdulilah M; Al-Ba'adani, Tawfiq H


    Background Renal replacement therapy was first introduced in Yemen in 1978 in the form of hemodialysis. Twenty years later, the first renal transplantation was performed. Kidney transplantations were started in socially and financially challenging circumstances in Yemen in 1998. A structured program was established and has been functioning regularly since 2005. A pediatric transplantation program was started in 2011. Material and Methods This was a prospective study of 181 transplants performed at the Urology and Nephrology Center between May 1998 and 2012. All transplants were from living related donors. The immunosuppressive protocol consisted initially of double therapy with steroid and mycophenolate mofetil (MMF). Subsequently, triple therapy with addition of a calcineurin inhibitor was introduced. Primary graft function was achieved in 176 (97.2%) recipients. Results Cold ischemia time was 48-68 min. Episodes of acute rejection in 12 patients were treated with high-dose steroids. Anti-thymocyte globulin (ATG) was used in cases of vascular or steroid-resistant rejection in 2 patients. The post-transplant complications, either surgical or medical, were comparable to those recorded in the literature. Conclusions Renal transplantation is a good achievement in our country. The patients and graft survival rates are comparable to other reports.

  19. Maximizing the right renal vein length in laparoscopic live donor nephrectomy

    Anibal W. Branco


    Full Text Available Laparoscopic donor nephrectomy has become the standard of care at increasing numbers of renal transplant programs worldwide. The majority of laparoscopic living donor kidneys are procured from the left side because of the longer renal vein and improved transplantation. The aim of this article is to report a technique to maximize the right renal vein length by performing a hand-assisted cavotomy.

  20. Fecal microbiota transplantation and donor standardization.

    Owens, Casey; Broussard, Elizabeth; Surawicz, Christina


    Clostridium difficile diarrhea is a common and severe infectious disease. Antibiotics, which are standard initial treatment, are less effective for treating refractory or recurrent infection. Fecal microbiota transplantation, where healthy donor stool is transplanted into a patient, is an alternative to antibiotic therapy that requires standardization for donors and patients.

  1. [Living donor liver transplantation in adults].

    Neumann, U P; Neuhaus, P; Schmeding, M


    The worldwide shortage of adequate donor organs implies that living donor liver transplantation represents a valuable alternative to cadaveric transplantation. In addition to the complex surgical procedure the correct identification of eligible donors and recipients plays a decisive role in living donor liver transplantation. Donor safety must be of ultimate priority and overrules all other aspects involved. In contrast to the slightly receding numbers in Europe and North America, in recent years Asian programs have enjoyed constantly increasing living donor activity. The experience of the past 15 years has clearly demonstrated that technical challenges of both bile duct anastomosis and venous outflow of the graft significantly influence postoperative outcome. While short-term in-hospital morbidity remains increased compared to cadaveric transplantation, long-term survival of both graft and patient are comparable or even better than in deceased donor transplantation. Especially for patients expecting long waiting times under the MELD allocation system, living donor liver transplantation offers an excellent therapeutic alternative. Expanding the so-called "Milan criteria" for HCC patients with the option for living donor liver transplantation is currently being controversially debated.

  2. Receptores de trasplante renal de donantes en asistolia y muerte cerebral: diferencias en los cuidados enfermeros Recipients of kidney transplants from donors in asystole and brain death: differences in nursing care

    Mª Concepción García Viana


    Full Text Available Hoy en día es indiscutible que el trasplante renal es el tratamiento sustitutivo de elección para pacientes con enfermedad renal crónica. En nuestro hospital realizamos fundamentalmente dos tipos de trasplante renal, el clásico donante en muerte cerebral y el donante en asistolia. El objetivo de nuestro estudio fue evaluar si existían diferencias en las cargas de trabajo del personal de enfermería dependiendo de un tipo de trasplante u otro. Se trata de un estudio transversal con 73 pacientes que recibieron un trasplante renal durante el año 2010, 18 procedentes de donante en muerte cerebral y 55 en asistolia. Los trasplante renales de donante en asistolia presentaron mayor incidencia de fallo primario del injerto (15% vs 1,4% así como mayor retraso de la función renal (18 días vs 0 días. Debido a esto, nuestra labor asistencial se vio incrementada en este tipo de trasplante por precisar un mayor número de biopsias renales que implican unos cuidados de preparación y de vigilancia de sus complicaciones, la necesidad de más sesiones de hemodiálisis y la administración de un mayor número de dosis de timoglobulina. No se objetivaron diferencias significativas en la incidencia de infecciones entre ambos tipo de trasplante, así como en la estancia media hospitalaria, aunque esto último podría estar influido por el tamaño de la muestra. A pesar de las complicaciones mencionadas, la función renal a medio plazo de ambos tipos de trasplante fue similar, lo que alienta la utilización de los donantes en asistolia.Nowadays it is indisputable that kidney transplant is the preferred replacement therapy for patients with chronic kidney disease. In our hospital we carry out basically two types of kidney transplants, the classic brain dead donor and the asystolic donor. The aim of our study was to evaluate whether there were differences in the workload of nursing staff depending on the type of transplant. This is a transversal study of 73

  3. Outcome of Laparoscopic Live Donor Nephrectomy and Impact of Double Renal Arteries: Results From Two Transplant Centres

    Tricia Kuo


    Conclusion: Our results showed that overall donor morbidity rate was low, as reflected by the short hospital stay. Also, the overall parameters of the recipients were good. In particular, no ureteric stricture was noted, and graft survival was 100% at 1 year. The outcomes of the reconstructed group, despite the technical challenge, were similar to those of the single-vessel group.

  4. Identification of the optimal donor quality scoring system and measure of early renal function in kidney transplantation.

    Moore, Jason


    The early identification of kidney allografts at risk of later dysfunction has implications for clinical practice. Donor quality scoring systems (preoperative) and measures of early allograft function (first week postoperative) have previously shown practical utility. This study aimed to determine the optimal parameter(s) (preoperative and postoperative) with greatest predictive power for the development of subsequent allograft dysfunction.

  5. Successful renal transplantation during pregnancy.

    Hold, Phoebe M; Wong, Christopher F; Dhanda, Raman K; Walkinshaw, Steve A; Bakran, Ali


    Little is known about the implications of performing a renal transplant on a patient who is already pregnant. This case study reports a successful outcome of pregnancy, diagnosed coincidentally following renal transplantation at 13 weeks gestation. The recipient was a 23-year-old woman with chronic kidney disease who received a live-related renal transplant from her father. Pregnancy was discovered at routine ultrasound scanning of the renal allograft at 5 days posttransplant and estimated at 13 weeks gestation. She received ciclosporin monotherapy as immunosuppression throughout the pregnancy, and was given valacyclovir as prophylaxis against cytomegalovirus (CMV) infection. Renal function remained stable throughout the pregnancy, which progressed normally, resulting in the vaginal delivery of a healthy, liveborn male infant at 37 weeks gestation. This case study demonstrates that transplantation during pregnancy can have a successful outcome.

  8. Bilateral Psoas Haematomata Complicating Renal Transplantation

    Jacob A. Akoh


    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

  9. Factors influencing weight gain after renal transplantation.

    Johnson, C P; Gallagher-Lepak, S; Zhu, Y R; Porth, C; Kelber, S; Roza, A M; Adams, M B


    Weight gain following renal transplantation occurs frequently but has not been investigated quantitatively. A retrospective chart review of 115 adult renal transplant recipients was used to describe patterns of weight gain during the first 5 years after transplantation. Only 23 subjects (21%) were overweight before their transplant. Sixty-six subjects (57%) experienced a weight gain of greater than or equal to 10%, and 49 subjects (43%) were overweight according to Metropolitan relative weight criteria at 1 year after transplantation. There was an inverse correlation between advancing age and weight gain, with the youngest patients (18-29 years) having a 13.3% weight gain and the oldest patients (age greater than 50 years) having the lowest gain of 8.3% at 1 year (P = 0.047). Black recipients experienced a greater weight gain than whites during the first posttransplant year (14.6% vs. 9.0%; P = 0.043), and maintained or increased this difference over the 5-year period. Men and women experienced comparable weight gain during the first year (9.5% vs. 12.1%), but women continued to gain weight throughout the 5-year study (21.0% total weight gain). The men remained stable after the first year (10.8% total weight gain). Recipients who experienced at least a 10% weight gain also increased their serum cholesterol (mean 261 vs. 219) and triglyceride (mean 277 vs. 159) levels significantly, whereas those without weight gain did not. Weight gain did not correlate with cumulative steroid dose, donor source (living-related versus cadaver), rejection history, pre-existing obesity, the number of months on dialysis before transplantation, or posttransplant renal function. Posttransplant weight gain is related mainly to demographic factors, not to treatment factors associated with the transplant. The average weight gain during the first year after renal transplantation is approximately 10%. This increased weight, coupled with changes in lipid metabolism, may be significant in

  10. Cadaveric renal transplantation: the Chennai experience.

    Prabahar, M R; Soundararajan, P


    Transplantation of human organs is undoubtedly one of the greatest medical breakthroughs of this century. However, few Indian patients are able to benefit from this medical advance. It is estimated that in India every year over 152,000 people are diagnosed to have end-stage renal failure needing renal transplantation. The Transplantation of Human Organs Act passed by the Indian parliament in 1994 was subsequently ratified by the state legislature of Tamil Nadu in May 1995. It accepted brain death as a form of death and prohibited commerce in organs. The first cadaveric kidney transplant in Sri Ramachandra medical college was performed in 1995 with 68 cadaveric kidney transplants thereafter. The mean age of the donors was 36 +/- 12.8 years. The mean cold ischemia time was 5.6 +/- 3.2 hours. As many as 14 donors displayed acute renal failure (serum creatinine more than 1.2 mg/dL). Immediate graft function was established in 34 patients (50%). Four had graft rupture, two of which were successfully repaired. Postoperatively 12 patients (17.6%) displayed delayed graft function requiring dialysis. During the first year, 18 patients (26.4%) experienced acute rejection episodes, of which 14 were cellular and four vascular rejection types. As many as eight patients were lost to follow-up within one year; the mean follow-up time was 968 +/- 86 days. Patient survival at 1 year was 88.2% and that of the graft 73.5%. The 5-year patient and graft survival rates were 61.7% and 58.8%, respectively. The mean serum creatinine of patients currently followed is 2.2 +/- 0.86 mg/dL. The rate of cadaver kidney transplantation in India is low despite initiatives by our university to promote donation. Creating a positive public attitude, early brain death identification, and certification, prompt consent for organ donation, adequate hospital infrastructure, and support logistics are prerequisites for successful organ transplantation.

  11. Physical Activity and Renal Transplantation

    Vincenzo Bellizzi


    Full Text Available Renal transplantation is burdened by high cardiovascular risk because of increased prevalence of traditional and disease-specific cardiovascular risk factors and, consequently, patients are affected by greater morbidity and mortality. In renal transplanted patients, healthy lifestyle and physical activity are recommended to improve overall morbidity and cardiovascular outcomes. According to METs (Metabolic Equivalent Task; i.e. the amount of energy consumed while sitting at rest, physical activities are classified as sedentary (<3.0 METs, of moderate-(3.0 to 5.9 METs or vigorous-intensity (≥6.0 METs. Guidelines suggest for patients with chronic kidney disease an amount of physical activity of at least 30 minutes of moderate-intensity activity five times per week (min 450 MET-minutes/week. Data on physical activity in renal transplanted patients, however, are limited and have been mainly obtained by mean of non-objective methods. Available data suggest that physical activity is low either at the start or during renal transplantation and this may be associated with poor patient and graft outcomes. Therefore, in renal transplanted patients more data on physical activity obtained with objective, accelerometer-based methods are needed. In the meanwhile, physical activity have to be considered as an essential part of the medical care for renal transplanted recipients.

  12. The first two cadaveric renal transplantations in Blida, Algeria.

    Si-ahmed, E M


    Currently, living related donor renal transplantation is the most common source for transplantation in Algeria. To develop cadaveric organ donation, the Blida Transplantation Team (BTT) started a local education program and campaign. On March 31, 2010, we procured and transplanted 2 kidneys from a 17-year-old brain-dead donor. The BTT is conscious that the local initiative must be followed nationally, with the help of the health authorities. There is an urgent need to promote brain-dead donors and cadaveric organ retriveal throughout the country. It will also be necessary to create national waiting lists for candidates not only for renal, but also for other organ transplantations. Copyright © 2011 Elsevier Inc. All rights reserved.

  13. Historical perspective of living donor liver transplantation

    See Ching Chan; Sheung Tat Fan


    Living donor liver transplantation (LDLT) has gone through its formative years and established as a legitimate treatment when a deceased donor liver graft is not timely or simply not available at all. Nevertheless,LDLT is characterized by its technical complexity and ethical controversy. These are the consequences of a single organ having to serve two subjects, the donor and the recipient, instantaneously. The transplant community has a common ground on assuring donor safety while achieving predictable recipient success. With this background, a reflection of the development of LDLT may be appropriate to direct future research and patient- care efforts on this life-saving treatment alternative.

  14. The living kidney donor evaluation: focus on renal issues.

    Kher, Ajay; Mandelbrot, Didier A


    Living kidney donor evaluations and follow-up have previously been addressed mostly by transplant physicians and surgeons. However, this area is significantly informed by basic principles of renal physiology and is of increasing clinical interest to general nephrologists. The general nephrology community is increasingly involved in evaluating the suitability of potential donors and in following them after donation when questions are raised about low GFR, hypertension, and other renal concerns. This article focuses on some of the most central and common issues that arise in evaluating potential donors and attempts to provide guidance on the basis of our review of the living donor literature, extrapolations from the general nephrology literature, and our own clinical experience.

    Full Text Available We report a case of renal transplantation using a horseshoe kidney from a living, genetically unrelated donor. The recipient was a 60-year-old man with diabetic nephropathy, and the donor was the 63-year-old wife of the recipient with a horseshoe kidney free of complications. Computed tomography showed two renal arteries and one renal vein on the left side, and the isthmus was perfused by several accessory arteries and veins. To demarcate the boundary of the isthmus, the left renal artery was ligated and cannulated for in situ perfusion. Furthermore, the isthmus was clamped, and the boundary of the isthmus was confirmed. The kidney was divided at the left margin of the perfused boundary. The cut ends of the isthmus were closed by sutures. The left kidney was transplanted into the right iliac fossa of the recipient. Asymptomatic fluid collection occurred on the cut surface at the isthmus of the donor, and this fluid decreased in due course. On the other hand, the recipient experienced no surgical complication or rejection, while maintaining serum creatinine levels of 2.00–2.20 mg/dL over a 22-month follow-up period. Horseshoe kidneys may be used for transplantation in selected cases after a detailed preoperative evaluation.

  16. Protocol biopsies for renal transplantation

    Rush David


    Full Text Available Protocol biopsies in renal transplantation are those that are procured at predetermined times post renal transplantation, regardless of renal function. These biopsies have been useful to study the natural history of the transplanted kidney as they have detected unexpected - i.e. "subclinical" pathology. The most significant subclinical pathologies that have been detected with protocol biopsies have been acute lesions, such as cellular and antibody mediated rejection, and chronic lesions, such as interstitial fibrosis and tubular atrophy, and transplant glomerulopathy. The potential benefit of early recognition of the above lesions is that their early treatment may result in improved long-term outcomes. Conversely, the identification of normal histology on a protocol biopsy, may inform us about the safety of reduction in overall immunosuppression. Our centre, as well as others, is attempting to develop non-invasive methods of immune monitoring of renal transplant patients. However, we believe that until such methods have been developed and validated, the protocol biopsy will remain an indispensable tool for the complete care of renal transplant patients.

    Freedman, Barry I.; Pastan, Stephen O.; Israni, Ajay K.; Schladt, David; Julian, Bruce A.; Gautreaux, Michael D.; Hauptfeld, Vera; Bray, Robert A.; Gebel, Howard M.; Kirk, Allan D.; Gaston, Robert S.; Rogers, Jeffrey; Farney, Alan C.; Orlando, Giuseppe; Stratta, Robert J.; Mohan, Sumit; Ma, Lijun; Langefeld, Carl D.; Bowden, Donald W.; Hicks, Pamela J.; Palmer, Nicholette D.; Palanisamy, Amudha; Reeves-Daniel, Amber M.; Brown, W. Mark; Divers, Jasmin


    Background Two apolipoprotein L1 gene (APOL1) renal-risk variants in donors and African American (AA) recipient race are associated with worse allograft survival in deceased-donor kidney transplantation (DDKT) from AA donors. To detect other factors impacting allograft survival from deceased AA kidney donors, APOL1 renal-risk variants were genotyped in additional AA kidney donors. Methods APOL1 genotypes were linked to outcomes in 478 newly analyzed DDKTs in the Scientific Registry of Transplant Recipients. Multivariate analyses accounting for recipient age, sex, race, panel reactive antibody level, HLA match, cold ischemia time, donor age, and expanded-criteria donation were performed. These 478 transplantations and 675 DDKTs from a prior report were jointly analyzed. Results Fully-adjusted analyses limited to the new 478 DDKTs replicated shorter renal allograft survival in recipients of APOL1-two-renal-risk-variant kidneys (HR 2.00; p=0.03). Combined analysis of 1153 DDKTs from AA donors revealed donor APOL1 high-risk genotype (HR 2.05; p=3×10−4), older donor age (HR 1.18; p=0.05), and younger recipient age (HR 0.70; p=0.001) adversely impacted allograft survival. Although prolonged allograft survival was seen in many recipients of APOL1-two-renal-risk-variant kidneys, follow-up serum creatinine concentrations were higher than in recipients of zero/one APOL1-renal-risk variant kidneys. A competing risk analysis revealed that APOL1 impacted renal allograft survival, but not recipient survival. Interactions between donor age and APOL1 genotype on renal allograft survival were non-significant. Conclusions Shorter renal allograft survival is reproducibly observed after DDKT from APOL1-two-renal-risk-variant donors. Younger recipient age and older donor age have independent adverse effects on renal allograft survival. PMID:26566060

  18. Socioeconomic deprivation and barriers to live-donor kidney transplantation: a qualitative study of deceased-donor kidney transplant recipients.

    Bailey, Phillippa K; Ben-Shlomo, Yoav; Tomson, Charles R V; Owen-Smith, Amanda


    Socioeconomically deprived individuals with renal disease are less likely to receive a live-donor kidney transplant than less-deprived individuals. This qualitative study aimed to identify reasons for the observed socioeconomic disparity in live-donor kidney transplantation. A qualitative study using face-to-face in-depth semistructured interviews. A UK tertiary renal referral hospital and transplant centre. Purposive sampling was used to select deceased-donor transplant recipients from areas of high socioeconomic deprivation (SED) (19 participants), followed by a low SED comparison group (13 participants), aiming for maximum diversity in terms of age, gender, ethnicity, primary renal disease and previous renal replacement therapy. Participants were interviewed following their routine transplant clinic review. Interviews were digitally audio-recorded and transcribed verbatim. Transcripts were coded using NVivo software and analysed using the constant comparison method described in Grounded Theory. Themes common and distinct to each socioeconomic group emerged. 6 themes appeared to distinguish between individuals from areas of high and low SED. 4 themes were distinct to participants from areas of high SED: (1) Passivity, (2) Disempowerment, (3) Lack of social support and (4) Short-term focus. 2 themes were distinct to the low SED group: (1) Financial concerns and (2) Location of donor. Several of the emerging themes from the high SED individuals relate to an individual's lack of confidence and skill in managing their health and healthcare; themes that are in keeping with low levels of patient activation. Inadequate empowerment of socioeconomically deprived individuals by healthcare practitioners was also described. Financial concerns did not emerge as a barrier from interviews with the high SED group. Interventions aiming to redress the observed socioeconomic inequity should be targeted at both patients and clinical teams to increase empowerment and ensure shared

    Full Text Available The main objective of this study is to provide a database for renal transplantation in Sudan and to determine the HLA antigens and haplotype frequencies (HFs in the study subjects. HLA typing was performed using the complement-dependant lymphocytotoxicity test in 250 unrelated healthy individuals selected as donors in the Sudanese Renal Transplantation Program. Considerable polymorphism was observed at each locus; A2 (0.28, A30 (0.12, A3 (0.09, A24 (0.09, A1 (0.09, and A68 (0.06 were the most frequent antigens in the A locus, while B51 (0.092, B41 (0.081, B39 (0.078, B57 (0.060, B35 (0.068, B 50 (0.053 and B 52 (0.051 were the most common B locus antigens. DR13 (0.444 and DR15 (0.160 showed the highest antigen frequencies (AFs in the DR locus. In the DQ locus, DQ1 showed the highest gene frequency (0.498, while DQ2 and DQ3 AFs were (0.185 and (0.238, respectively. The most common HLA-A and -B haplotypes in positive linkage disequilibrium were A24, B38; A1, B7; and A3, B52. The common HLA-A and -B HFs in positive linkage disequilibrium in the main three tribe-stocks of the study subjects (Gaalia, Nile Nubian and Johyna were A24, B38 for Gaalia; A24, B38 and A2, B7 for Johyna; and A2, B64 and A3, B53 for Nile Nubian. These results suggest that both class I and class II polymorphisms of the study subjects depict considerable heterogeneity, which reflects recent admixture of this group with neighboring Arabs and African populations.

  1. Nocardia infection in a renal transplant recipient

    K K Kaswan


    Full Text Available Opportunistic infection occurs in up to 20% renal transplant patients and is associated with a high mortality. We report a 47-year-old diabetic female with 1-year-old deceased donor renal allograft on triple drug immunosuppression. She developed cytomegalovirus retinitis at ten months post-transplant followed by nocardiasis manifested by hemiparesis with comatose state due to lumbar epidural and multiple brain abscesses, in spite of immediately curtailing immunosuppression. She recovered with linezolid and cotrimoxazole and was discharged two weeks later. She is maintaining stable graft function with serum creatinine 1.4 mg/dL on cyclosporin 2.5 mg/kg/day and prednisone10 mg/day with maintenance therapy for nocardiasis.

  2. Non-contrast magnetic resonance angiography in renal transplantation and renal donation

    Blankholm, Anne Dorte


    examination of living kidney donors. We compared CTA to an extensive MRI protocol without the use of contrast agents, including NCMRA, and to observations from living donor nephrectomy, which served as the reference standard. We concluded that an optimised MRI protocol without contrast agents could...... be substituted for CTA for preoperative vessel assessment in living kidney donors.......Renal transplantation is the treatment of choice in cases of severe renal disease. The majority of candidates for kidney transplantation have arteriosclerosis to some extent; thus, preoperative imaging of the vessels is needed. Different imaging modalities are available and are used...

  3. Outcomes of shipped live donor kidney transplants compared with traditional living donor kidney transplants.

    Treat, Eric G; Miller, Eric T; Kwan, Lorna; Connor, Sarah E; Maliski, Sally L; Hicks, Elisabeth M; Williams, Kristen C; Whitted, Lauren A; Gritsch, Hans A; McGuire, Suzanne M; Mone, Thomas D; Veale, Jeffrey L


    The disparity between kidney transplant candidates and donors necessitates innovations to increase organ availability. Transporting kidneys allows for living donors and recipients to undergo surgery with a familiar transplant team, city, friends, and family. The effect of shipping kidneys and prolonged cold ischemia time (CIT) with living donor transplantation outcomes is not clearly known. This retrospective matched (age, gender, race, and year of procedure) cohort study compared allograft outcomes for shipped live donor kidney transplants and nonshipped living donor kidney transplants. Fifty-seven shipped live donor kidneys were transplanted from 31 institutions in 26 cities. The mean shipping distance was 1634 miles (range 123-2811) with mean CIT of 12.1 ± 2.8 h. The incidence of delayed graft function in the shipped cohort was 1.8% (1/57) compared to 0% (0/57) in the nonshipped cohort. The 1-year allograft survival was 98% in both cohorts. There were no significant differences between the mean serum creatinine values or the rates of serum creatinine decline in the immediate postoperative period even after adjusted for gender and differences in recipient and donor BMI. Despite prolonged CITs, outcomes for shipped live donor kidney transplants were similar when compared to matched nonshipped living donor kidney transplants.

  4. Skin Findings in Renal Transplantation Patients

    Demet Kartal


    Full Text Available Objective: It was aimed to identify skin findings those were seen in patients who undergone renal transplantation. Methods: Patients who have been followed in Erciyes University Nephrology Hospital renal transplantation outpatient clinic were included in the study. They were evaluated for dermatologic findings during routine controls. Age, gender, transplantation date, identity of organ donor, history of medications, dermatological history and dermatological findings during examination were recorded. Biopsy was performed when needed. Results: In total 94 patients, 25 female (26.6% and 69 male (73.4%, were recruited to the study. Mean age was 36±10 years. The most frequent skin finding was drug-related acne (n=20. Most common infectious disease was verruca (n=17. There were viral disease other than verruca such as herpes zoster (n=3, superficial mycosis such as onychomycosis (n=5, tinea versicolor, tinea pedis and bacterial skin disease (n=2, and paronychia (n=1 and pre-malign lesions such as actinic cheilitis and bowenoid papulosis. Besides these, stria (n=3, kserosis (n=2, cornu cutaneum, café-au-lait spots, sebaceous hyperplasia and seborrheic dermatitis, skin tag, hypertrichosis, unguis incarinatus and calcinosis were other skin findings those were seen. No malign skin lesion was observed in any of patients. Conclusion: Miscellaneous skin lesions should develop in patients those undergone renal transplantation due to long-term utilization of various immunosuppressive drugs.

  5. Microvascular Disease After Renal Transplantation

    Qi Lun Ooi


    Full Text Available Background/Aims: Individuals who reach end-stage kidney disease (CKD5 have a high risk of vascular events that persists even after renal transplantation. This study compared the prevalence and severity of microvascular disease in transplant recipients and patients with CKD5. Methods: Individuals with a renal transplant or CKD5 were recruited consecutively from renal clinics, and underwent bilateral retinal photography (Canon CR5-45, Canon. Their retinal images were deidentified and reviewed for hypertensive/microvascular signs by an ophthalmologist and a trained grader (Wong and Mitchell classification, and for vessel caliber at a grading centre using a computer-assisted method and Knudtson's modification of the Parr-Hubbard formula. Results: Ninety-two transplant recipients (median duration 6.4 years, range 0.8 to 28.8 and 70 subjects with CKD5 were studied. Transplant recipients were younger (pConclusions: Hypertensive/microvascular disease occurred just as often and was generally as severe in transplant recipients and subjects with CKD5. Microvascular disease potentially contributes to increased cardiac events post- transplantation.

  6. Diabetes and Renal Transplantation: Saudi Experience

    Souqiyyeh Muhammad


    Full Text Available We conducted this study to evaluate the prevalence and risk factors of diabetes mellitus (DM in our renal transplant population. We retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia, transplanted between 1979 and November 1998. The recipients were grouped according to the diagnosis of diabetes; group I: diabetes developed before transplantation (BTDM, group II: diabetes developed only after transplantation (ATDM and group III: did not have diabetes (NDM. There were 1112 patients′ records included in the study. The mean age was 38.2 years and the mean duration of transplantation was 66.9 months. There were 113(10.2% patients in BTDM group, 134 (12.1% patients in the ATDM group and 865 (77.8% patients in the NDM group. There was no significant difference in the prevalence of hypertension among the study groups. In comparison to the other groups, the BTDM group had significantly more males (78.8%, more patients who were transplanted after 1990 (pre-cyclosporin era, more patients with grafts from living non-related donors (46%, higher incidence of acute rejection episodes (39%, higher mean serum creatinine and more patients treated with azathioprine (71%. The ATDM group had significantly higher mean age (46.4 years, higher mean duration of transplantation (91.5 months, higher rate of retransplantation (8.2%, higher mean serum cholesterol level (6.0mmol/L and more frequently abnormal electrocardiogram (24.6% than the other two groups. The ATDM group had comparable mean weight (70.2 kg to the BTDM group but significantly higher than the NDM group (66.1kg. The NDM group had significantly higher mean dose of cyclosporine (3.3 mg/kg/day and higher mean dose of prednisone (0.16 mg/kg/day than the other groups. The only independent risk factor for developing DM after transplantation was advancing age. The currently used low-dose steroid therapy was not

  7. Pregnancy in renal transplant recipients.

    Fuchs, Karin M; Wu, Danny; Ebcioglu, Zeynep


    Women with renal disease face increasing infertility and high-risk pregnancy as they approach end-stage renal disease due to uremia. Renal transplantation has provided these patients the ability to return to a better quality of life, and for a number of women who are of child bearing age with renal disease, it has restored their fertility and provided the opportunity to have children. But, although fertility is restored, pregnancy in these women still harbors risk to the mother, graft, and fetus. Selected patients who have stable graft function can have successful pregnancies under the supervision of a multidisciplinary team involving maternal fetal medicine specialists and transplant nephrologists. Careful observation and management are required to optimize outcome for mother and fetus.

  8. Acute leukaemia following renal transplantation.

    Subar, M; Gucalp, R; Benstein, J; Williams, G; Wiernik, P H


    Four renal transplant patients on immunosuppressive therapy who presented with acute myeloid leukaemia are described. In two cases, azathioprine may have played an important role as a cofactor in leukaemogenesis. In a third case, the alkylating agent cyclophosphamide may have contributed. All patients were treated for leukaemia with full doses of cytotoxic chemotherapy and, in each case, a functioning renal allograft was preserved throughout the treatment despite attenuation of immunosuppressive therapy. Three patients achieved complete remission. Of the three, one is surviving at 2 years and two expired during the pancytopenic phase of their treatment with no active leukaemia present, and with intact renal function. As increasing expertise in the field of organ transplantation allows patients to survive longer, such patients' exposure to immunosuppressive and potentially leukaemogenic drugs is prolonged. The risk of secondary neoplasia has been previously documented in this population. Two of the four cases reported here suffered from polycystic kidney disease as their underlying condition. While this report suggests that the leukaemias are related to renal transplantation, we cannot rule out an association with the underlying disease which led to the transplant. This report further suggests that the leukaemia that develops in such patients may respond to standard therapy, and that such treatment does not compromise the transplanted kidney.

  9. Gastrointestinal complications in renal transplantation

    Kamal Jeet Singh


    Full Text Available Objective: Gastrointestinal complications are responsible for substantial morbidity and mortality among renal allograft recipients. We retrospectively analyzed incidence of these complications and their impact on the patient outcome. Materials & Methods: Between 1998 to Aug 2002, 558 live related renal transplants were performed at our center. The immunosuppression used consisted mainly of cyclosporine, azathioprine and prednisolone, though varied in some patients. These patients were followed for any occurrence of significant gastrointestinal problems. Results: Out of the of 538 renal transplant recipients studied, gastro esophageal ulcerations were seen in 3% patients. Acute pancreatitis was observed in twelve (2.2% patients and four patients had acute intestinal obstruction secondary to fecal impaction. Infectious complications included acute diarrheas in 18% of patients. Three patients developed abdominal tuberculosis. Acute rejection episodes were encountered in 26% of the patients. During these episodes, 58% of patients experienced prolonged ileus. Most of these complications (66% occurred within first one-year post transplant. Three patients presenting with acute intestinal obstruction required laparotomy (two- bands, one-intussusception. There were four mortalities -two patients had severe pancreatitis, one patient had massive upper GI bleed and one succumbed due to perforation peritonitis. Conclusions: Gastrointestinal complications account for significant morbidity and mortality in renal transplant recipients. Paralytic ileus secondary to acute vascular rejection is quite common and resolves spontaneously with recovery of renal function.

  10. Pediatric renal transplantation: a single center experience

    João Nascimento


    Full Text Available Introduction: End-stage renal disease in children is associated with numerous comorbidities and with age-specific mortality rates approximately 30 times higher than in healthy children. The first kidney transplantation in children was performed successfully in 1954. Surgical advances and new immunosuppressive medications have greatly improved patient’s and graft’s survival in the last years. Aim: Report Centro Hospitalar do Porto experience in pediatric renal transplantation in the last 30 years. Methods: Epidemiological and clinical data of all patients younger than 18 years, transplanted between January 1984 and August 2013, were collected from our database. In order to analyze the transplantation outcome in our center we compare graft survival between decades (1984-89 / 1990-99 / 2000-09 / 2010-13. We also compare graft survival between two age groups of patients (0-10 years ; 11-17 years at the time of surgery. Results: One hundred thirty-nine patients (58.3% male underwent 147 renal transplants (6.8% live donors. Congenital anomalies of the kidney and urinary tract (56.5% and glomerulonephritis (18.4% were the major causes of renal disease. Uncensored graft survivals rates at 5, 10, 15 and 20 years were 84.7%, 71.1%, 60.0% and 51.0%, while patient survivals were 97.9%, 95.9%, 94.7% and 94.7% respectively. Graft survival improved over time and the difference between the decades was statistically significant (p=0.004. Despite the better survival in the group of patients older than 11 years, graft’s survival difference between the two age groups was not statistically significant (p=0.697. Conclusion: The results of our hospital are comparable to other international centers. Significant improvement in survival was observed over the time. It seems that an accurate follow-up of our patients helps to minimize the negative impact of adolescence on graft survival rates.

  11. How deceased donor transplantation is impacting a decline in commercial transplantation-the Tamil Nadu experience.

    Abraham, Georgi; Reddy, Yuvaram N V; Amalorpavanathan, Joseph; Daniel, Dolly; Roy-Chaudhury, Prabir; Shroff, Sunil; Reddy, Yogesh


    India with a population of 1.2 billion has a renal transplantation rate of 3.25 per million population. The major cause of chronic kidney disease is hypertension and diabetes. The crude and age-adjusted incidence rates of end-stage renal disease are estimated to be 151 and 232 per million population, respectively, in India. There was a remarkable lack of knowledge in the public about deceased organ donation until a decade ago. However, the role played by the media and nongovernmental organizations in partnership with the government has emphasized and implemented deceased donor transplantation in certain states in India-to mention particularly, the Tamil Nadu model. In the last 2 years, deceased organ donation has reached 1.3 per million population in Tamil Nadu, thereby effectively eliminating commercial transplantation. There is no religious bar for organ donation. A central transplant coordinator appointed by the government oversees legitimate and transparent allocation of deceased organs both in the public and private facilities as per the transplant waiting list. This model also takes care of the poor sections of society by conducting donation and transplantation through government-run public facilities free of cost. In the last 2 years, deceased donor transplantation has been performed through this network procuring organs such as the heart, heart valves, lung, liver, kidneys, cornea, and skin. The infrastructural lack of immunological surveillance-including donor-specific antibody monitoring, human leukocyte antigen typing, and panel reactive antibody except in a few tertiary care centers-prevents allocation according to the immunological status of the recipient. This private-public partnership promoting deceased donor transplantation has effectively eliminated commercialization in transplantation in the state of Tamil Nadu with a population of 72 million which is a model for other regions of South Asia and developing countries.

  12. The Iranian model of living renal transplantation.

    Mahdavi-Mazdeh, Mitra


    Organ shortage for transplantation remains a worldwide serious problem for kidney patients with end-stage renal failure, and several countries have tried different models to address this issue. Iran has 20 years of experience with one such model that involves the active role of the government and charity foundations. Patients with a desperate demand for a kidney have given rise to a black market of brokers and other forms of organ commercialism only accessible to those with sufficient financial resources. The current Iranian model has enabled most of the Iranian kidney transplant candidates, irrespective of socioeconomic class, to have access to kidney transplantation. The Iranian government has committed a large budget through funding hospital and staff at the Ministry of Health and Medical Education by supporting the brain death donation (BDD) program or redirecting part of the budget of living unrelated renal donation (LURD) to the BDD program. It has been shown that it did not prevent the development and progression of a BDD program. However, the LURD program is characterized by several controversial procedures (e.g., confrontation of donor and recipient at the end of the evaluation procedure along with some financial interactions) that should be ethically reviewed. Operational weaknesses such as the lack of a registration system and long-term follow-up of the donors are identified as the 'Achilles heel of the model'.

  13. Living unrelated donor kidney transplantation: A fourteen-year experience

    Ignjatović Ljiljana


    Full Text Available Background. In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors. Method. We retrospectively identified 14 patients who received renal allograft from spousal donors between 1996 and 2009 (group I. The control group consisted of 14 patients who got graft from related donor retrieved from the database and matched than with respect to sex, age, kidney disease, immunological and viral pretransplant status, the initial method of the end stage renal disease treatment and ABO compatibility. In the follow-up period of 41 ± 38 months we recorded immunosuppressive therapy, surgical complications, episodes of acute rejection, CMV infection and graft function, assessed by serum creatinine levels at the beginning and in the end of the follow-up period. All patients had pretransplant negative cross-match. In ABO incompatible patients pretransplant isoagglutinine titer was zero. Results. The patients with a spousal donor had worse HLA matching. There were no significant differences between the groups in surgical, infective, immunological complications and graft function. Two patients from the group I returned to hemodialysis after 82 and 22 months due to serious comorbidities. Conclusion. In spite of the worse HLA matching, graft survival and function of renal grafts from spousal donors were as good as those retrieved from related donors.

  14. [Kidney donors and kidney transplantation in the elderly].

    Giessing, M; Conrad, S; Schönberger, B; Huland, H; Budde, K; Neumayer, H-H; Loening, S A


    The likelihood of terminal renal insufficiency escalates with age, increasing the risk of dying as a patient requiring dialysis. In 1999, Eurotransplant initiated the Eurotransplant Senior Programm (ESP), in which the kidneys of old donors (>64 years) are allocated to recipients 64 years and older. Allocation does not take HLA-matching into account and is performed regionally only according to blood-group-compatibility to keep the storage time short. As a consequence of the short ischemic time, and thus reduced non-immunological damage to the anyways susceptible old kidney, graft-function and graft-survival in the ESP are very good. The results of the initial 5 years of this program show that it successfully utilizes more kidneys from old donors and that more old recipients are being transplanted, with a satisfactory graft-function. Increased donor- and/or recipient age require a thorough evaluation to exclude malignant and other diseases. Furthermore, short term controls on the waiting list and following kidney transplantation are prerequisites for successful transplantation in the aged recipient. If this is guaranteed, kidney transplantation in the old recipient-even with old donor organs-is a good alternative to the morbidity of a prolonged dialysis. Nevertheless, the role of HLA-matching should be reconsidered to reduce rejections.

  15. Predictive capacity of pre-donation GFR and renal reserve capacity for donor renal function after living kidney donation

    Rook, M; Hofker, HS; van Son, WJ; van der Heide, JJH; Ploeg, RJ; Navis, GJ


    Kidney transplantation from living donors is important to reduce organ shortage. Reliable pre-operative estimation of post-donation renal function is essential. We evaluated the predictive potential of pre-donation glomerular filtration rate (GFR) (iothalamate) and renal reserve capacity for post-do

  16. Five years renal transplantation data: Single-center experience from Iraq

    Ala A Ali


    Full Text Available Renal transplantation is the treatment of choice for patients with end-stage renal disease. In Iraq, renal transplantation started in 1973 and has continued until now with live donor transplantation, since deceased donor transplant program is not approved as yet. Long-term transplant data are still scarce. The aim of our study is to present data on transplantation and medical follow-up at one year and, survival analysis at one, three and five years. A total of 250 renal transplantations were performed at the Nephrology and Renal Transplantation Center, Baghdad between January 2009 and January 2014. It is a living donor, blood group compatible donor program. All patients received triple immunosuppression (calcineurine inhibitor, mycophenolate mofetil or mycophenolic acid, and steroid. The Kaplan-Meier method was used to determine the survival rate. There were 92 live related donors, 143 unrelated donors, and 15 spouse donors. The mean age was 34.07 ± 12.2 years. The one-year graft survival for related and unrelated donor transplants was 98.9% and 91.8%, respectively. Graft survival was lower (82.9% in recipients with acute rejection episodes. The patient survival at one-year was 94%. The three-year graft and patient survival was 91% and 90%, respectively, and five-year survival for grafts and patients was 87.1% and 88%, respectively. The outcome of the renal transplantation in Iraq is improving. Long-term patient follow-up needs more meticulous attention. The development of renal transplant registry is critical for future planning. Moreover, renal transplantation practice in Iraq needs more social, religious, and governmental support.

  17. Hypertension in Renal Transplantation: Saudi Arabian Experience

    Souqiyyeh Muhammad


    Full Text Available To evaluate the prevalence, etiologic factors and therapy of hypertension in actively followed up transplant population in Saudi Arabia; we retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia. These subjects were transplanted between January 1979 and November 1998. The patients were grouped according to the measurement of blood pressure; group 1 (considered normo-tensive: blood pressure below 140/90 mmHg, group2: blood pressure between 140-159/90-99, group 3: blood pressure 160-179/100-109 group 4: equal to or above 180/110. There were 1115 patients′ records included in the study. The mean duration of transplantation was 66.9 ± 50.1 months. According to the level of measured blood pressure, there were 641 (57.5% patients in the normotensive group (group 1, 404 (36.3% patients in the mildly hypertensive group (group 2 64 (5.7% patients in the moderately severe hypertension group (group 3 and only six (0.5% patients in the severe hypertension group (group 4. The estimated prevalence of hypertension in this study was almost 85%. We found no significant difference in the prevalence of hypertension in terms of gender, year of transplantation, duration of transplantation, type of donor, number of previous transplants, diagnosis of renal artery stenosis, etiology of kidney disease, diagnosis of diabetes after transplantation, diagnosis of cerebrovascular accidents, or mean dose of prednisolone and cyclosporine. There was a statistically significant association between increased level of blood pressure and old age (above 50 years, original disease associated with hypertension, history of hypertension on dialysis, acute rejection (once or more, presence of protienuria (more than 0.3 mg/day, abnormality of ECG, or serum creatinine above 300 µmol/L. We conclude that hypertension is highly prevalent in the renal transplant population in Saudi Arabia. Risk

  18. Adult-to-Adult Living Donor Liver Transplantation

    Shimul A Shah


    Full Text Available The present review outlines the principles of living donor liver transplantation, donor workup, procedure and outcomes. Living donation offers a solution to the growing gap between the need for liver transplants and the limited availability of deceased donor organs. With a multidisciplinary team focused on donor safety and experienced surgeons capable of performing complex resection/reconstruction procedures, donor morbidity is low and recipient outcomes are comparable with results of deceased donor transplantation.

  19. Donor Considerations in Fecal Microbiota Transplantation.

    Barnes, Danielle; Park, K T


    Tremendous acceleration has been made in understanding the gut microbiota in the past decade and, with it, further understanding of the pathologic role of dysbiosis and the use of fecal microbiota transplantation (FMT) as therapy. FMT has been studied in many disease states including the most common indication of Clostridium difficile infection (CDI), though many questions regarding stool donor selection remain. Though traditionally, one donor has provided stool for one patient, research is underway to explore many donor selection considerations from the use of pooled donor stool to selection of a high diversity donor. It is well-known that dietary intake shapes the gut microbiota and the potential implications of this on FMT donor selection are being explored. Though further high-quality research is needed, optimizing the fecal microbiota inoculum holds great promise.

  20. [Pediatric renal transplantation in France. Introduction].

    Deschênes, Georges; Fila, Marc


    Pediatric nephrology is a relatively recent medical speciality. The first French center opened in January 1969 at the Hospital des Enfants-Malades. In 2008, according to the Réseau Épidémiologie et Information en Néphrologie (REIN), the annual incidence of end stage renal disease (ESRD) was of 7,8 children/million children below the age of 20, which equals a prevalence of 49 pediatric ESRD patients/million inhabitants. The frequency of causative factors of ESRD varies according to the geographic and ethnic origin of the patients. Many challenges still lay ahead of ESRD management. The children's physical, psychological and social development has to be well taken care of until adulthood and the transition from pediatric to adult unit has to be handled with special care. The set up of pediatric nephrology departments helped to the access of patients to renal replacement therapy, in particular the pediatric priority for kidney donors below 30 years of age. In the 2000s period, the annual rate of pediatric renal transplantation was 70 to 75 grafts per year in France, half of which performed in the Paris area. This article presents the historical background of pediatric nephrology and pediatric renal transplantation in France.

  1. Review of Surgical Techniques of Experimental Renal Transplantation in Rats.

    Shrestha, Badri; Haylor, John


    Microvascular surgical techniques of renal transplant in rats have evolved over the past 5 decades to achieve successful rat renal transplant; these modifications have included surgical techniques to address the anatomic variations in the renal blood vessels and those to reduce ischemic and operation durations. Here, we review the surgical techniques of renal transplant in rats and evaluate the advantages and disadvantages of individual techniques of vascular and ureteric anastomoses. For this review, we performed a systematic literature search using relevant medical subject heading terms and included appropriate publications in the review. Since the first description of a rat model of renal transplant by Bernard Fisher and his colleagues in 1965, which used end-to-side anastomosis between the renal vein and renal artery to the recipient inferior vena cava and aorta, several vascular and ureteric anastomosis techniques have been modified. Vascular anastomosis techniques now include end-to-end anastomosis, use of donor aortic and inferior vena cava conduits, sleeve and cuff anastomoses, and application of fibrin glue. Likewise, restoration of the urinary tract can now be achieved by direct anastomosis of the donor ureter to the recipient bladder, end-to-end anastomosis between the donor and recipient ureters, and donor bladder cuff to the recipient bladder. There are advantages and disadvantages attributable to individual techniques. The range of vascular and ureteric anastomosis techniques that has emerged reflects the need for mastering more than one technique to suit the vascular anatomy of individual animals and to reduce operating time for achieving successful outcomes after renal transplant.

  2. Emphysematous prostatitis in renal transplant

    Krishnaswamy Sampathkumar


    Full Text Available Urinary tract infections are common following renal transplant. The spectrum varies from asymptomatic bacteriuria to septicemia. Gas-producing infections of the urinary tract are rare but tend to have a grave prognosis when they do occur. We report a 57-year-old gentleman who underwent a renal transplant 20 months earlier. He presented to us with fever and dysuria. Clinical examination revealed a febrile and ill-looking patient with severe graft tenderness. An emergency pelvic CT scan revealed presence of emphysematous prostatitis, cystitis and pyelitis. Urine and blood cultures grew E. coli . Endoscopic abscess drainage was done and antibiotics given but he succumbed to his illness due to multiorgan failure within 48h. This is the first reported case of emphysematous prostatitis in a renal allograft recipient.

  3. Rejection is a strong graft survival predictor in live donor pediatric renal transplantation using cyclosporine, mycophenolate mofetil, and steroids: 5-year outcomes in a single Mexican center.

    Martinez-Mier, G; Enriquez-De Los Santos, H; Méndez-López, M T; Avila-Pardo, S F; Budar-Fernandez, L F; Gonzalez-Velazquez, F


    Long-term graft function and survival are of particular importance in children assuming that they have a longer transplantation life span than most adults. Because acute rejection episodes (ARE) continue to have a serious impact on graft loss, we analyzed the effects of ARE on 5-year survival and function in our population. Fifty-seven living donor kidney transplant recipients (34 males) younger than 18 years of age (13.5 ± 2.6 years; range, 5-17) were follow up for at feast 12 months using cyclosporine, mycophenolate mofetil, and steroid therapy with or without induction treatment between February 2003 and December 2010. ARE incidence during the first 12 months following transplantation was 14%. One-, 3- and 5-year serum creatinine values were 1.24 ± 0.39, 2.16 ± 2.39, and 1.76 ± 0.9 mg/dL, respectively. Mean calculated creatinine clearances (Schwartz) at 1, 3, and 5 years were 82.5 ± 24.8, 64.7 ± 24.1, and 67 ± 27.5 mL/min*1.73 m(2), respectively. Patient/graft survival rates were 96/85%, 90/72%, and 88/65% at 1, 3, and 5 years, respectively. Patients who experienced an ARE within 12 months following transplantation displayed a reduced 5-year graft survival rate (37.5%) versus those who did not (78%; P = .005). Patients who did not have an ARE during 60 months had a higher graft survival rate (76%) than those who had ARE (33%; P = .001). Patient without basiliximab induction showed a lower 5-year graft survival rate (61% vs 100%; P = not significant [NS]). ARE is an important risk factor for graft loss in the pediatric kidney transplant population. Copyright © 2013 Elsevier Inc. All rights reserved.

  4. [Ethics and kidney transplants with living donors].

    Mamzer Bruneel, Marie-France


    The ethical debate surrounding transplant practices questions our societies. International recommendations set out numerous precautions which must be taken to ensure that donors act with their free will. While in most countries, including France, organ donation is a voluntary and non-commercial act, a black market exists in the world resulting in the trafficking of organs and tragic transplant tourism.

  5. Evaluation of renal donors and recipients using intravenous digital subtraction angiography

    Choi, Deuk Lin; Kim, Ki Jeung [Soonchunhyang Medical College, Seoul (Korea, Republic of)


    Renal IV DSA was applied to evaluate 15 potential renal donors and 14 examinations of 12 renal allograft recipients. We evaluate the angiographic acute or chronic rejection, alteration of renal size after transplantation, excretion time of the contrast media and pre, post DSA serum creatinine level. DSA is a safe, easily performed, outpatient procedure and useful in evaluation and distinguishing status of surgical anastomosis, intrarenal vasculatures, arterial exception time and rejection phenomenon.

  6. Attitudes toward live donor kidney transplantation and its commercialization.

    Mazaris, Evangelos M; Crane, Jeremy S; Warrens, Anthony N; Smith, Glenn; Tekkis, Paris; Papalois, Vassilios E


    Development of live donor kidney transplantation (LDKT) programs has intensified debate regarding acceptability of certain donor categories and potential commercialization. Concerning these issues, we surveyed the views of medical and nursing staff caring for patients with renal failure and renal transplant recipients and donors. Participants were recruited from a tertiary transplant unit and invited to complete an anonymous questionnaire. Four hundred and sixty-four participants completed the questionnaire (42% response). One hundred and sixty-eight (36.2%) were health care professionals and 296 (63.8%) patients; 85.6% of participants were willing to donate to their children, 80.2% to siblings, 80.8% to parents, 72% to a non-blood-related relative or friend, and 15.3% to a stranger. If participants had hypothetical renal failure, they were prepared to accept a kidney from a parent (79.5%), sibling (78.7%), child (56.3%), a non-blood-related relative or friend (79.3%), or stranger (54.1%). Regarding commercialization, responders' attitudes were that the donor should not accept financial reward (29.1%), be compensated for expenses only (60.6%), or should receive a direct financial reward (10.1%). For non-directed donation, 23.5%, 55.6%, and 20.7% were not in support of reward, compensation only, and financial reward, respectively. While live kidney donation was accepted by the majority of individuals surveyed, only the minority approved of commercialization. © 2011 John Wiley & Sons A/S.

    Nobuhisa Akamatsu; Yasuhiko Sugawara; Sumihito Tamura; Junichi Keneko; Yuichi Matsui; Kiyoshi Hasegawa; Masatoshi Makuuchi


    AIM: To investigate the incidence and risk factors of late-onset acute rejection (LAR) and to clarify the effectiveness of our immunosuppressive regime consisting of life-long administration of tacrolimus and steroids.METHODS: Adult living donor liver transplantation recipients (n = 204) who survived more than 6 mo after living donor liver transplantation were enrolled.Immunosuppression was achieved using tacrolimus and methylprednisolone. When adverse effects of tacrolimus were detected, the patient was switched to cyclosporine. Six months after transplantation,tacrolimus or cyclosporine was carefully maintained at a therapeutic level. The methylprednisolone dosage was maintained at 0.05 mg/kg per day by oral administration.Acute rejections that occurred more than 6 mo after the operation were defined as late-onset. The median followup period was 34 mo.RESULTS: LAR was observed in 15 cases (7%) and no chronic rejection was observed. The incidence of hyperlipidemia, chronic renal failure, new-onset posttransplantation diabetes, and deep fungal infection were 13%, 2%, 24%, and 17%, respectively. Conversion from tacrolimus to cyclosporine was required in 38 patients (19%). Multivariate analysis revealed that a cyclosporinebased regimen was significantly associated with LAR.CONCLUSION: Both LAR and drug-induced adverse events happen at a low incidence, supporting the safety and efficacy of the present immunosuppression regimen for living donor liver transplantation.

  8. Imaging chronic renal disease and renal transplant in children

    Carmichael, Jim; Easty, Marina [Great Ormond Street Hospital, Radiology Department, London (United Kingdom)


    At Great Ormond Street Hospital we have the highest number of paediatric renal transplant patients in Europe, taking cases from across the United Kingdom and abroad. Our caseload includes many children with rare complicating medical problems and chronic renal failure related morbidity. This review aims to provide an overview of our experience of imaging children with chronic renal failure and transplants. (orig.)

  9. [Towards the development of living donor kidney transplantation].

    Macher, Marie-Alice


    Living donor kidney transplantation has been increasing since 2008. Living donors represent a significant potential for organ transplants, in a context where the needs outstrip the availability of organs from deceased donors. However, patients are still poorly informed regarding the conditions in which these transplants are possible. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Embora a anemia falciforme e as síndromes falciformes freqüentemente causem várias alterações funcionais renais, não é comum a insuficiência renal terminal. Nestes casos, o transplante renal é uma alternativa que se acompanha de resultados comparáveis aos obtidos em receptores sem hemoglobinopatias. Esta estratégia terapêutica tem sido, no entanto, pouco relatada para portadores de hemoglobinopatia SC. Este relato descreve a evolução de dois pacientes portadores de hemoglobinopatia SC que for...

  11. Dream anxiety in renal transplant recipients.

    Yazla, Ece; Ozkurt, Sultan; Musmul, Ahmet


    Although low quality of sleep has been reported in kidney transplant patients with functioning allografts, there are no previous studies investigating the dreams of these patients. We aimed to investigate the differences in dream anxiety level between renal transplant patients and healthy control subjects. We also planned to compare depression and anxiety symptoms, sleep quality and sleepiness level between these two groups. Twenty-two living-donor renal transplant recipients followed at an outpatient nephrology clinic and 22 healthy controls were enrolled in this observational cross-sectional study. Sociodemographic Data Collection Form, and the Van Dream Anxiety Scale (VDAS), the Pittsburg Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), Beck Depression and Anxiety Inventories were used for the assessment of the necessary features. Hemoglobin (Hb), blood urea nitrogen (BUN), creatinine (Cr) and glucose levels were measured. There were no significant differences between the groups in terms of dream anxiety (p = 0.45), depression (p = 0.76), sleep quality (p = 0.8), insomnia severity (p = 0.08) and Hb (p = 0.11) and glucose levels (p = 0.14). Although, BUN (p = 0.00) and creatinine (p = 0.00) levels differed significantly between the two groups, both parameters were found to be within their normal range. In our study, chronic renal failure patients with a successful kidney transplant were found to be able to completely return to normal in terms of metabolic parameters, sleep quality and mood. Similar levels of dream anxiety are also consistent with these findings.

  12. Opportunistic infections following renal transplantation

    Rao K


    Full Text Available Opportunistic infection is common following renal transplantation. Prompt diagnosis and management can be life saving. Four different types of opportunistic respiratory infections diagnosed at our center during the period of January 1998 to December 2000 are discussed. Of the four cases one had Aspergillus, second had Sporothrix, third had Nocardia and fourth case Actinomyces species. Microbiologist has an important role to play by being aware of such opportunistic infections and helping the clinician to make early aetiological diagnosis.

    Choi, Jung Bin; Choi, Yo Won; Jeon, Seok Chol; Park, Choong Ki; Lee, Seung Rho; Hahm, Chang Kok; Joo, Kyung Bin [Hanyang University College of Medicine, Seoul (Korea, Republic of)


    To evaluate the radiographic and CT findings of pulmonary complications other than pulmonary edema arising from renal transplantation. Among 393 patients who had undergone renal transplantation at our hospital during a previous ten-year period, 23 with pulmonary complications other than pulmonary edema were included in this study. The complications involved were infection caused by CMV (n=6), bacteria (n=4), fungus (n=4), tuberculosis (n=2), varicella (n=1) or chlamydia (n=1), and malignancy involving lung cancer (n=4) or Kaposi's sarcoma (n=1). Two chest radiologists reviewed all images. The complications manifesting mainly as pulmonary nodules were lung cancer (4/4), tuberculosis (1/2), and Kaposi's sarcoma (1/1). Pulmonary consolidation was a main feature in bacterial infection (4/4), fungal infection (3/4), tuberculosis (1/2), chlamydial infection (1/1), and varicellar pneumonia (1/1). Ground-glass attenuation was a main CT feature in CMV pneumonia (4/6), and increased interstitial making was a predominant radiographic feature in CMV pneumonia (2/6). The main radiologic features described above can be helpful for differential diagnosis of the pulmonary complications of renal transplantation.

  15. The Current Role of Endourologic Management of Renal Transplantation Complications

    Brian D. Duty


    Full Text Available Introduction. Complications following renal transplantation include ureteral obstruction, urinary leak and fistula, urinary retention, urolithiasis, and vesicoureteral reflux. These complications have traditionally been managed with open surgical correction, but minimally invasive techniques are being utilized frequently. Materials and Methods. A literature review was performed on the use of endourologic techniques for the management of urologic transplant complications. Results. Ureterovesical anastomotic stricture is the most common long-term urologic complication following renal transplantation. Direct vision endoureterotomy is successful in up to 79% of cases. Urinary leak is the most frequent renal transplant complication early in the postoperative period. Up to 62% of patients have been successfully treated with maximal decompression (nephrostomy tube, ureteral stent, and Foley catheter. Excellent outcomes have been reported following transurethral resection of the prostate shortly after transplantation for patients with urinary retention. Vesicoureteral reflux after renal transplant is common. Deflux injection has been shown to resolve reflux in up to 90% of patients with low-grade disease in the absence of high pressure voiding. Donor-gifted and de novo transplant calculi may be managed with shock wave, ureteroscopic, or percutaneous lithotripsy. Conclusions. Recent advances in equipment and technique have allowed many transplant patients with complications to be effectively managed endoscopically.

  16. New approaches to donor crossmatching and successful transplantation of highly sensitized patients.

    Delmonico, F L; Fuller, A; Cosimi, A B; Tolkoff-Rubin, N; Russell, P S; Rodey, G E; Fuller, T C


    A class I HLA molecule may bear not only a private or unique determinant, but a shared, yet discrete, public epitope. These public determinants occur with a much higher frequency in the random donor population than the associated private determinants--and thus, are encountered more often in random donor blood transfusions and in renal transplantation. Sera from highly sensitized dialysis patients have been reported to contain a restricted number of antibodies to public determinants rather than a diverse array of antibodies directed against the private HLA-AB epitopes. As detailed in this report, comprehensive serum analysis of the public antibodies in highly sensitized transplant candidates has optimized identification of potential crossmatch-compatible donors and has avoided needless crossmatches. During the past two years, the incidence of renal transplantation from cadaveric donors to highly sensitized recipients has doubled at this institution. At 10-25 months following transplantation, 70% of these allografts are functioning. Private HLA class I antigen incompatibility was not a barometer for exclusion in the final donor crossmatch of these highly sensitized recipients. Furthermore, positive donor T cell crossmatches with sera obtained more than six months prior to transplantation may not represent an impediment to successful transplantation. We conclude that the approach of detailed antibody analysis can result in an improved outlook for successful transplantation of more dialysis patients who are highly sensitized to the class I HLA alloantigens.

    Full Text Available Belatacept is a novel immunosuppressive agent that inhibits T-cell activation by blocking CD28 signaling pa- thway. It was developed based on abatacept (CTLA-4Ig, the first recombinant immunoglobulin fusion protein which contains extracellular part of CTLA-4 molecule and Fc domain of IgG. First clinical trials have shown the comparable patient and graft survival in group of kidney recipients with belatacept-based maintenance im- munosuppressive therapy versus Cyclosporin A-based therapy. Advantages observed with belatacept include superior glomerular filtration rate and improved cardiovascular risk profile. Belatacept is a potential option for maintenance immunosuppressive therapy without calcineurin inhibitors. Concerns associated with belatacept use are higher rates of acute cellular rejection episodes and post-transplant lymphoproliferative disorder cases. 

  18. Pediatric renal transplantation: Results and prognostic factors

    Po-Cheng Huang


    Conclusion: For pediatric patients, we found that renal transplantation is now a safe and effective surgical procedure for children with end-stage renal disease. Acute rejection and male gender were identified as prognostic factors for poor graft survival.

  19. Renal Vein Reconstruction for Harvesting Injury in Kidney Transplantation

    Birkan Bozkurt


    Full Text Available Kidney transplantation is the best treatment choice in the end-stage renal disease. In the renal transplantation, renal vein damage or shortness which occurs during cadaveric or living donor nephrectomy causes technical difficulties for surgeons. The lack of the donors already especially cadaveric, the acquirement of the graft, gets very much importance. In this report, it is aimed to share the clinical experiment by which it seen, how anastomosis can become appropriate by using the renal vein which is damaged in the way that anastomosis cannot be done anyway by using cadaveric vena cava graft. The renal vein brought to length for anostomosis which is repaired by using cadaveric vena cava graft, is anastomosed successfully by becoming an end-to-side of the external iliac vein of the recipient. Vascular anastomoses are applied easily in technique. The time of the warm ischemia was under 2 hours and the kidney was functional in the post-operative period. Renal vein trombosis was not observed. The renal vein damage occured during cadaveric or living donor nephrectomy, can be repaired by some methods. In the kidneys in which vein requirement is done, the success rates are rather high although acute tubular necrosis and delayed function can be seen more.

  20. Commercial cadaveric renal transplant: an ethical rather than medical issue.

    Sun, Chiao-Yin; Lee, Chin-Chan; Chang, Chiz-Tzung; Hung, Cheng-Chih; Wu, Mai-Szu


    Donor organ shortage is a universal problem. The organ source has been extended to controversial death-penalty outlaws in certain countries. It was claimed that commercial transplant had a worse short-term clinical outcome. The aim of this study is to investigate the long-term outcome of patients receiving commercial cadaveric renal transplant. Seventy-five renal transplant recipients receiving long-term follow-up were included. Thirty-one patients received overseas commercial cadaveric transplant. Forty-four patients had legal domestic transplant in Taiwan. The age of the patients receiving the commercial cadaveric transplant was significantly older than those with legal domestic transplant (commerical vs. legal: 46.1 +/- 11.4 vs. 35.6 +/- 9.0 yr old, p < 0.001). The renal function estimated by creatinine and 1/creatinine up to eight yr showed no significant difference between the two groups. The graft survivals of the two groups were not different. The mortality rate between the two groups was comparable in 10 yr (91.1% in domestic and 88.9% in overseas). There was no significant difference in de novo viral hepatitis, cytomegalovirus infection, and acute rejection. The clinical outcome of overseas commercial cadaveric transplant was not different from the domestic legal transplant. To stop the unethical procedure, ethnicity and humanity are the major concerns.

  1. Risks for donors in uterus transplantation.

    Kisu, Iori; Mihara, Makoto; Banno, Kouji; Umene, Kiyoko; Araki, Jun; Hara, Hisako; Suganuma, Nobuhiko; Aoki, Daisuke


    Uterus transplantation (UTx) is an alternative to gestational surrogacy and adoption for patients with absolute uterine infertility. Studies have been conducted in animals, and UTx is now within the reach of clinical application in humans. Procedures in humans have been published, but many medical, ethical, and social problems and risks of UTx require discussion prior to widespread clinical application, from the perspectives of donors, recipients, families, and newborns. In this article, we summarize the burdens and risks of UTx, with a focus on donors who provide the uterus.

  2. Machine perfusion for improving outcomes following renal transplant: current perspectives

    Cannon RM


    Full Text Available Robert M Cannon,1 Glen A Franklin1,2 1The Hiram C Polk Jr MD Department of Surgery, University of Louisville, 2Kentucky Organ Donor Affiliates, Louisville, KY, USAAbstract: There is a disparity between the number of kidneys available for transplantation and the number of patients awaiting an organ while on dialysis. The current kidney waiting list in the US contains more than 100,000 patients. This need has led to the inclusion of older donors with worsening renal function, as well as greater utilization of kidneys from non-heartbeating (donation after cardiac death donors. Coinciding with this trend has been a growing interest in technology to improve the function of these more marginal organs, the most important of which currently is machine perfusion (MP of donated kidneys after procurement. While this technology has no standard guidelines currently for comprehensive use, there are many studies that demonstrate higher organ yield and function after a period of MP. Particularly with the older donor and during donation after cardiac death cases, MP may offer some significant benefits. This manuscript reviews all of the current literature regarding MP and its role in renal transplantation. We will discuss both the experience in Europe and the US using machine perfusion for donated kidneys.Keywords: machine perfusion, renal transplantation, kidney pumping, renal failure, organ donation

  3. Tuberculosis in renal transplant recipients.

    Lattes, R; Radisic, M; Rial, M; Argento, J; Casadei, D


    Tuberculosis (TB) has been described in kidney transplant recipients as an infection with predominantly pulmonary involvement. We report the impact of TB in kidney transplantation. Clinical records of adult kidney recipients, transplanted between 1 January 1986 and 31 December 1995 were analyzed for sex, age, graft origin, immunosuppressive therapy, TB sites, diagnostic methods and concomitant infections. Annual incidence, mean time of onset, relation to rejection treatment, tuberculin skin test (PPD) and outcome were analyzed. Patients with a history of TB or graft loss in the first month were excluded. TB was diagnosed in 14 of 384 (3.64%). Mean age at transplantation was 35 years. Twelve of these received the graft from a living donor. All had triple immunosuppression with cyclosporine. Ten had pulmonary TB, three extrapulmonary infection and one disseminated disease. In 13 cases an invasive diagnostic procedure was performed. Mycobacterium tuberculosis cultures were positive in all cases; microscopy revealed acid-fast bacilli (AFB) in 6, and adenosine deaminase was elevated in CSF and pleural effusion in 2. Annual incidence varied from 0% to 3.1%. At the time of TB presentation 8 patients had other concomitant infections (cytomegalovirus, nocardia, Pneumocystis carinii, disseminated herpes simplex virus). Median time of onset was 13 months. Diagnostic results became available post-mortem in 2 cases, and one had TB in a failing allograft. TB was treated with 4 drugs including rifampin in 10 patients. Cyclosporine was discontinued in one, lowered in one and increased in 8. During treatment 5 patients had rejection episodes. At 1 year, graft survival was 72.7% and patient survival 90.9%. TB was more prevalent when recipient and donor were both PPD positive. In summary: although TB is a growing threat in the transplant setting, early and aggressive diagnosis with meticulous monitoring of immunosuppression allows a successful outcome for both patient and graft

  4. Infarction of renal transplant with extrarenal excretion of Tc-99m MAG{sub 3} demonstrated by renal scintigraphy

    Lim, Seok Tae; Kim, Min Woo; Sohn, Myung Hee [Chonbok National University Medical School, Chonju (Korea, Republic of)


    A 38-year-old woman with end stage renal disease received a living related donor-renal transplant to the right iliac fossa. She developed anuria a week later. Tc-99m MAG{sub 3} renal scintigraphy demonstrated no perfusion, uptake, or excretion of the radioactive tracer from the renal transplant. The expected area of the renal allograft appeared as a photopenic area with increased rim activity. The gallbladder and bowel activities were observed on delayed images at 24 hours. There was no blood flow within the renal artery on renal doppler examination. This case shows total absence of perfusion and function in the infarcted renal transplant with extrarenal excretion of Tc-99m MAG{sub 3} caused by acute renal artery thrombosis.

  5. The new technique of using the epigastric arteries in renal transplantation with multiple renal arteries

    Mohammad Ali Amirzargar


    Full Text Available The most common anatomic variant seen in the donor kidneys for renal transplantation is multiple renal arteries (MRA, which can cause an increased risk of complications. We describe the long-term outcomes of 16 years of experience in 76 kidney transplantations with MRAs. In a new reconstruction technique, we remove arterial clamps after anastomosing the donor to the recipient′s main renal vessels, which cause backflow from accessory arteries to prevent thrombosis. By this technique, we reduce the ischemic times as well as the operating times. Both in live or cadaver donor kidneys, lower polar arteries were anastomosed to the inferior epigastric artery and upper polar arteries were anastomosed to the superior epigastric arteries. Injection of Papaverine and ablation of sympathic nerves of these arteries dilate and prevent them from post-operative spasm. Follow-up DTPA renal scan in all patients showed good perfusion and function of the transplanted kidney, except two cases of polar arterial thrombosis. Mean creatinine levels during at least two years of follow-up remained acceptable. Patient and graft survival were excellent. No cases of ATN, hypertension, rejection and urologic complications were found. In conclusion, this technique can be safely and successfully utilized for renal transplantation with kidneys having MRAs, and may be associated with a lower complication rate and better graft function compared with the existing techniques.

  6. Fungal infection following renal transplantation.

    Gallis, H A; Berman, R A; Cate, T R; Hamilton, J D; Gunnells, J C; Stickel, D L


    Twenty-seven deep fungal infections developed in 22 of 171 patients following renal transplantation. These infections included cryptococcosis (ten), nocardiosis (seven), candidiasis (four), aspergillosis (two), phycomycosis (two), chromomycosis (one), and subcutaneous infection with Phialophora gougeroti (one). Twelve infections occurred in living-related and ten in cadaveric recipients. Nineteen of the 22 patients were male. Infections occurred from 0 to 61 months after transplantation. Complicating non-fungal infections were present concomitantly in 15 patients. Thirteen patients died, eight probably as a result of fungal infection. Appropriate diagnostic procedures yielded a diagnosis in 20 of 27 infections, and therapy was begun in 18 patients. Serologic, culture, and biopsy procedures useful in making rapid diagnoses are advocated in the hope of increasing survival.

None of the recipients with native ureter ligated had infection or post-ligation flank pain,no hydrone-phrosis was found by ultrasonography in

  8. Detection of acute renal allograft rejection by analysis of renal tissue proteomics in rat models of renal transplantation

    Dai Yong


    Full Text Available At present, the diagnosis of renal allograft rejection requires a renal biopsy. Clinical management of renal transplant patients would be improved if rapid, noninvasive and reliable biomarkers of rejection were available. This study is designed to determine whether such protein biomarkers can be found in renal-graft tissue proteomic approach. Orthotopic kidney transplantations were performed using Fisher (F344 or Lewis rats as donors and Lewis rats as recipients. Hence, there were two groups of renal transplant models: one is allograft (from F344 to Lewis rats; another is syngrafts (from Lewis to Lewis rats serving as control. Renal tissues were collected 3, 7 and 14 days after transplantation. As many as 18 samples were analyzed by 2-D Electrophoresis and mass spectrometry (MALDI-TOF-TOF-MS. Eleven differentially expressed proteins were identified between groups. In conclusion, proteomic technology can detect renal tissue proteins associated with acute renal allograft rejection. Identification of these proteins as diagnostic markers for rejection in patients′ urine or sera may be useful and non-invasive, and these proteins might serve as novel therapeutic targets that also help to improve the understanding of mechanism of renal rejection.

    Rizzoni, G; Malekzadeh, M H; Pennisi, A J; Ettenger, R B; Uittenbogaart, C H; Fine, R N


    19 young children (less than 5 years old) have received 31 renal transplants from 4 live relatives and 27 cadaver donors. The 2-year allograft survival rate for the patients receiving their 1st allograft from the 4 live donors was 75 +/- 22% while for the patients receiving their 1st allograft from 15 cadaver donors was 26 +/- 11%. 10 children are currently surviving with functioning allographs (7 cadavers and 3 live relatives); 4 have died and 5 are undergoing dialysis after the loss of at least one allograft. Despite the poor allograft survival rate the fact that 7 children are surviving with cadaver allografts indicates that the lack of a living related donor should not prevent transplants in young children.

    Historically, donor age above 55 years has been considered to be a relative contraindication for organ transplantation. The shortage of organs for transplantation has led to the expansion of the donor pool by accepling older donors. To compare the 1 year follow-up in patients after lung transplantation from older donors (> 50 years old) and in patients after transplantation from younger donors ( 50 years (n = 9). Survival, number and total days of hospitalization, development of bronchiolitis obliterans syndrome, and pulmonary function tests, were examined 1 year after transplantation. We performed 29 lung transplantations in our center during the observed period. Donor age had no statistically significant impact on 1 year survival after lung transplantation. There was no statistically significant effect on lung function parameters, the incidence of hospitalization or the incidence of bronchiolitis obliterans between both donor age groups at 1 year after transplantation. Donor age did not influence survival or important secondary end-points 1 year after lung transplantation By liberalizing donor criteria of age up to 65 years, we can expand the donor pool, while assessing other possible mechanisms to increase donor availability.

  11. Renal transplantation in patients with HIV.

    Frassetto, Lynda A; Tan-Tam, Clara; Stock, Peter G


    HIV infection has been a major global health problem for almost three decades. With the introduction of highly active antiretroviral therapy in 1996, and the advent of effective prophylaxis and management of opportunistic infections, AIDS mortality has decreased markedly. In developed countries, this once fatal infection is now being treated as a chronic condition. As a result, rates of morbidity and mortality from other medical conditions leading to end-stage liver, kidney and heart disease are steadily increasing in individuals with HIV. Presence of HIV infection used to be viewed as a contraindication to transplantation for multiple reasons: concerns for exacerbation of an already immunocompromised state by administration of additional immunosuppressants; the use of a limited supply of donor organs with unknown long-term outcomes; and, the risk of viral transmission to the surgical and medical staff. This Review examines open questions on kidney transplantation in patients infected with HIV-1 and clinical strategies that have resulted in good outcomes. It also describes the clinical concerns associated with the treatment of renal transplant recipients with HIV.

    Peces, R; Navascués, R A; Baltar, J; Laurés, A S; Ortega, F; Alvarez-Grande, J


    We report a case of toxic multinodular goiter with severe symptomatic hyperthyroidism in a female diagnosed 5 months after successful renal transplantation. To our knowledge, this is the first well-documented case of hyperthyroidism in a renal transplant recipient that responded well to methimazole. Special attention should be made to the use of methimazole and the possible interaction with immunosuppressive drugs.

    We report a very rare case of a false iliac artery aneurysm following renal transplantation. The patient was a 51-year-old women who presented with a painful 10 x 10 cm pulsating mass in her left iliac fossa. The patient had received a second cadaveric renal transplantation 5 years previously...

  14. The Changing Financial Landscape of Renal Transplant Practice: A National Cohort Analysis.

    Axelrod, D A; Schnitzler, M A; Xiao, H; Naik, A S; Segev, D L; Dharnidharka, V R; Brennan, D C; Lentine, K L


    Kidney transplantation has become more resource intensive as recipient complexity has increased and average donor quality has diminished over time. A national retrospective cohort study was performed to assess the impact of kidney donor and recipient characteristics on transplant center cost (exclusive of organ acquisition) and Medicare reimbursement. Data from the national transplant registry, University HealthSystem Consortium hospital costs, and Medicare payments for deceased donor (N = 53 862) and living donor (N = 36 715) transplants from 2002 to 2013 were linked and analyzed using multivariate linear regression modeling. Deceased donor kidney transplant costs were correlated with recipient (Expected Post Transplant Survival Score, degree of allosensitization, obesity, cause of renal failure), donor (age, cause of death, donation after cardiac death, terminal creatinine), and transplant (histocompatibility matching) characteristics. Living donor costs rose sharply with higher degrees of allosensitization, and were also associated with obesity, cause of renal failure, recipient work status, and 0-ABDR mismatching. Analysis of Medicare payments for a subsample of 24 809 transplants demonstrated minimal correlation with patient and donor characteristics. In conclusion, the complexity in the landscape of kidney transplantation increases center costs, posing financial disincentives that may reduce organ utilization and limit access for higher-risk populations.

  15. Cyclosporine nephrotoxicity and early posttransplant hyperkalemia in living-donor renal recipients: report of 4 cases.

    Pavleska-Kuzmanovska, Svetlana; Popov, Zivko; Ivanovski, Ognen; Ristovska, Vesna; Masin-Spasovska, Jelka; Rambabova-Busljetic, Irena; Ivanovski, Ninoslav


    Hyperkalemia is an electrolyte disorder that may occur during the first few months after a renal transplant, in patients undergoing cyclosporine immunosuppression. We present our experience with cyclosporine-associated hyperkalemia in living-donor renal transplant recipients, with isolated clinically relevant hyperkalemia soon after surgery. We report 4 living-donor renal recipients with hyperkalemia soon after transplant. Severe unexpected hyperkalemia (7.5- 9.4 mmol/L) was noted in our patients 12, 20, 22, and 34 days after transplant. The C2 cyclosporine concentration was within recommended range or slightly greater than 1200 ng/mL. The hypertonic glucose/insulin treatment along with potassium diet was without results. A reduction in daily cyclosporine dosages, along with 1- to 2-week administration of fludrocortisone was effective. The patients became normokalemic taking a standard, triple-drug immunosuppression protocol, and were discharged home with normal renal function. There were no repeat episodes of hyperkalemia in any of the patients during 12 months of follow-up. Cyclosporine should be considered a cause of hyperkalemia in renal transplant recipients. Successful treatment with fludrocortisone confirms that transitional pseudohypoaldosteronism has a potential nephrotoxic effect of cyclosporine. We recommend close monitoring of the cyclosporine concentration and administering fludrocortisone when treating hyperkalemia in renal transplant recipients.

  16. CUBN as a novel locus for end-stage renal disease: insights from renal transplantation.

    Anna Reznichenko

    Full Text Available Chronic kidney disease (CKD is a complex disorder. As genome-wide association studies identified cubilin gene CUBN as a locus for albuminuria, and urinary protein loss is a risk factor for progressive CKD, we tested the hypothesis that common genetic variants in CUBN are associated with end-stage renal disease (ESRD and proteinuria. First, a total of 1142 patients with ESRD, admitted for renal transplantation, and 1186 donors were genotyped for SNPs rs7918972 and rs1801239 (case-control study. The rs7918972 minor allele frequency (MAF was higher in ESRD patients comparing to kidney donors, implicating an increased risk for ESRD (OR 1.39, p = 0.0004 in native kidneys. Second, after transplantation recipients were followed for 5.8 [3.8-9.2] years (longitudinal study documenting ESRD in transplanted kidneys--graft failure (GF. During post-transplant follow-up 92 (9.6% cases of death-censored GF occurred. Donor rs7918972 MAF, representing genotype of the transplanted kidney, was 16.3% in GF vs 10.7% in cases with functioning graft. Consistently, a multivariate Cox regression analysis showed that donor rs7918972 is a predictor of GF, although statistical significance was not reached (HR 1.53, p = 0.055. There was no association of recipient rs7918972 with GF. Rs1801239 was not associated with ESRD or GF. In line with an association with the outcome, donor rs7918972 was associated with elevated proteinuria levels cross-sectionally at 1 year after transplantation. Thus, we identified CUBN rs7918972 as a novel risk variant for renal function loss in two independent settings: ESRD in native kidneys and GF in transplanted kidneys.

    Prolonged cold ischemia time (CIT) is associated with a significant risk of short- and long-term graft failure in deceased donor kidney transplants across the world. The aim of this prospective longitudinal study was to determine the importance of logistical factors on CIT. Data on 1763 transplants were collected prospectively over 14 months from personnel in 16 transplant centers, 19 histocompatibility and immunogenetics laboratories, transport providers, and National Health Service Blood and Transplant. The overall mean CIT was 13.8 hours, with significant center variation (P theater access contributes significantly to increased CIT. This study identifies logistical factors relating to donor, transport, crossmatching, recipient, and theater that impact significantly on CIT in deceased donor renal transplantation, some of which are modifiable; attention should be focussed on addressing all of these.

  18. Uses and limitations of renal scintigraphy in renal transplantation monitoring

    Heaf, J.G. [Department of Nephrology, Herlev Hospital, University of Copenhagen (Denmark); Iversen, J. [Department of Clinical Physiology, Herlev Hospital, University of Copenhagen (Denmark)


    The value of thrice weekly technetium-99m mercaptoacetyltriglycine renography after renal transplantation was investigated in 213 consecutive transplants. A grading system was used: 0 = normal renogram; 1 = normal uptake, reduced excretion; 2 = normal uptake, flat excretion curve; 3 = rising curve; 4 = reduced rate of uptake, rising curve and reduced absolute uptake; 5 = minimal uptake. The initial renogram grade (RG) was primarily a marker of ischaemic damage, being poorer with cadaver donation, long cold ischaemia (>24 h), and high donor and recipient age. High primary RG predicted primary graft non-function, long time to graft function, low discharge Cr EDTA clearance and low 1- and 5-year graft survival. Discharge RG predicted late (>6 months) graft loss. RG was highly correlated (P<0.001) with creatinine and creatinine clearance, and changes in RG were correlated with changes in renal function. A change in RG of 0.5 was non-specific, while a change of 1 or more predicted clinical complications in 95% of cases. The negative predictive value was low (58%). RG change antedated clinical diagnosis in only 38% of cases, and in only 14% of acute rejections did an RG change of 1 or more antedate a rising creatinine. RG did not contribute to the differential diagnosis between acute rejection, acute tubulointerstitial nephropathy and cyclosporine toxicity. In conclusion, an initial renography after transplantation is valuable as it measures ischaemic damage and predicts duration of graft non-function and both short and long-term graft survival. A review of the literature suggests that the indication for serial scintigraphic monitoring for functioning grafts is less certain: the diagnostic specificity is insufficient for it to be the definitive investigation for common diagnostic problems and it does not give sufficient advance warning of impending problems.

  19. Surgical complications in pediatric and adolescent renal transplantation

    El Atat Rabih


    Full Text Available To report the surgical complications among our pediatric and adolescent renal transplants and to compare these results with other reported series in the literature. A total of 50 pediatric and adolescent renal transplants were included in this study. There were 30 boys and 20 girls with a mean age of 13 years (range 6 - 18 years. 70% of patients received their kidneys from living donors. Two patients underwent renal re-transplantation. Among the 52 transplantations, 17 surgical complications were encountered in 15(30% patients. The incidence of urological and vascular complications was respectively 13.2% and 18.9%. These complications included vesico-ureteral reflux (9.4%, urinary leakage (3.8%, lymphocele (5.8%, peri-renal hematoma (1.9%, renal artery stenosis (3.7%, and thrombosis of the allograft (7.5%. The patients with vesico-ureteral reflux were treated by antibiotic prophylaxis. In four recipients, thrombosis of the allo-graft with subsequent graft loss occurred. The graft survival rate was 90% in 1 year, 77% in 5 years and 40% in 10 years follow-up. The patient survival rate was 94.4% in 1 year and 84% after 8 years follow-up. We conclude that surgical complications can be minimized if basic principles of careful transplant techniques are used. Prompt identification and treatment of any complication are critical for graft and patient survival.

    Komeno, Yukiko; Kanda, Yoshinobu; Kandabashi, Koji; Kawazu, Masahito; Goyama, Susumu; Takeshita, Masataka; Nannya, Yasuhito; Niino, Miyuki; Nakamoto, Tetsuya; Kurokawa, Mineo; Tsujino, Shiho; Ogawa, Seishi; Aoki, Katsunori; Chiba, Shigeru; Motokura, Toru; Hirai, Hisamaru


    A male patient had a relapse of myelodysplastic syndrome (MDS) 2 years after BMT from a female matched unrelated donor. Conventional cytogenetics, FISH, and short-tandem repeat chimerism analysis proved a relapse of donor origin. He underwent reduced-intensity BMT after a conditioning with fludarabine and busulfan, since he had impaired renal, liver, and pulmonary functions. Chimerism analysis on day 28 after the second BMT showed mixed chimerism of the first and the second donors, which later turned to full second-donor chimerism on day 60. He developed grade II acute GVHD of the skin and cytomegalovirus reactivation, but both were improved with methylprednisolone and ganciclovir, respectively. He remains in complete remission 6 months after the second BMT. Reduced-intensity second BMT from an alternative donor appeared to be a tolerable treatment option for donor-derived leukemia/MDS after the first conventional transplantation.

  1. Donor-specific antibodies accelerate arteriosclerosis after kidney transplantation.

    Hill, Gary S; Nochy, Dominique; Bruneval, Patrick; Duong van Huyen, J P; Glotz, Denis; Suberbielle, Caroline; Zuber, Julien; Anglicheau, Dany; Empana, Jean-Philippe; Legendre, Christophe; Loupy, Alexandre


    In biopsies of renal allografts, arteriosclerosis is often more severe than expected based on the age of the donor, even without a history of rejection vasculitis. To determine whether preformed donor-specific antibodies (DSAs) may contribute to the severity of arteriosclerosis, we examined protocol biopsies from patients with (n=40) or without (n=59) DSA after excluding those with any evidence of vasculitis. Among DSA-positive patients, arteriosclerosis significantly progressed between month 3 and month 12 after transplant (mean Banff cv score 0.65 ± 0.11 to 1.12 ± 0.10, P=0.014); in contrast, among DSA-negative patients, we did not detect a statistically significant progression during the same timeframe (mean Banff cv score 0.65 ± 0.11 to 0.81 ± 0.10, P=not significant). Available biopsies at later time points supported a rate of progression of arteriosclerosis in DSA-negative patients that was approximately one third that in DSA-positive patients. Accelerated arteriosclerosis was significantly associated with peritubular capillary leukocytic infiltration, glomerulitis, subclinical antibody-mediated rejection, and interstitial inflammation. In conclusion, these data support the hypothesis that donor-specific antibodies dramatically accelerate post-transplant progression of arteriosclerosis.

  2. Human Leukocyte Antigen Alleles and Cytomegalovirus Infection After Renal Transplantation



    . Results of multivariate logistic regression analysis showed that deceased donor renal transplantation (OR = 3.018, 95%CI: 1.662 - 5.480, P < 0.001, presence of HLA-B44 (OR = 4.764, 95%CI: 1.259 - 18.032, P = 0.022 and lack of HLA-B8 (OR = 3.246, 95%CI: 1.030 - 10.230, P = 0.044 were the independent risk factors for developing CMV infection, after kidney transplantation. Conclusions The findings of this study showed that deceased donor renal transplantation and the presence of HLA-B44 can make the kidney recipient susceptible to CMV infection after kidney transplantation; on the other hand, the presence of HLA-B8 can have a protective effect.

    Full Text Available BACKGROUND The kidney and the skin are the two large networks of the body with abundant blood supply associated with various cutaneous manifestations. This study aims to detect the various cutaneous manifestations and its incidence in patients with chronic renal failure and renal transplantation. MATERIALS AND METHODS This study was done for a period of 1 year from January 2016 to December 2016 at Nephrology OPD ward and Medicine wards, Government KAPV Medical College Hospital, Trichy. During this period, 100 patients who had the presence of skin manifestations were selected and studied (80 renal failure patients and 20 renal transplantation patients. RESULTS Most of the specific cutaneous manifestations of chronic renal failure and renal transplantation were noted in this study. Pruritus and xerosis were the most common manifestations noted in chronic renal failure while infections was commonly noted in renal transplantation patients. CONCLUSION Pruritus and xerosis were the most common among the specific cutaneous manifestations in chronic renal failure followed by nail abnormalities and pigmentary changes. Cutaneous manifestations of renal transplantation were mostly due to infections of which fungal infection is the most common followed by viral infection.

  4. Overextended Criteria Donors: Experience of an Italian Transplantation Center.

    Nure, E; Lirosi, M C; Frongillo, F; Bianco, G; Silvestrini, N; Fiorillo, C; Sganga, G; Agnes, S


    The increasing gap between the number of patients who could benefit from liver transplantation and the number of available donors has fueled efforts to maximize the donor pool using marginal grafts that usually were discarded for transplantation. This study included data of all patients who received decreased donor liver grafts between January 2004 and January 2013 (n = 218) with the use of a prospectively collected database. Patients with acute liver failure, retransplantation, pediatric transplantation, and split liver transplantation were excluded. Donors were classified as standard donor (SD), extended criteria donor (ECD), and overextended criteria donor (OECD). The primary endpoints of the study were early allograft primary dysfunction (PDF), primary nonfunction (PNF), and patient survival (PS), whereas incidence of major postoperative complications was the secondary endpoint. In our series we demonstrated that OECD have similar outcome in terms of survival and incidence of complication after liver transplantation as ideal grafts.

  5. Demodicosis in Renal Transplant Recipients.

    Chovatiya, R J; Colegio, O R


    Solid organ transplant recipients have an increased incidence of skin infections resulting from immunosuppression. Common pathogens include herpes simplex virus, varicella zoster virus, Gram-positive bacteria and dermatophytes; however, the contribution of multicellular parasitic organisms to dermatologic disease in this population remains less studied. Demodex folliculorum and brevis are commensal mites that reside on human skin. Proliferation of Demodex mites, or demodicosis, is associated with rosacea and rosacea-like disorders, particularly in immunocompromised populations, although their ability to cause disease is still the subject of debate. We present a case series of four renal transplant recipients with the singular chief complaint of acne rosacea who we diagnosed with demodicosis. Although one of the four patients showed complete resolution following initial antiparasitic therapy, the other three required subsequent antibacterial treatment to fully resolve their lesions. We suggest that demodicosis may be more prevalent than once thought in solid organ transplant recipients and showed that Demodex-associated acne rosacea can be effectively treated in this population.

  6. Renal function after solid organ transplantation

    Broekroelofs, Jan


    The studies described in this thesis focus on the problem of renal chronic function loss following solid organ transplantation form a nephrologist point of view. Nephrologists have been and are still confionted with renal function loss in native kidney diseases. The last 3 decades chronic renal func

  7. Presymptomatic testing for adult onset polycystic kidney disease in at-risk kidney transplant donors.

    Hannig, V L; Hopkins, J R; Johnson, H K; Phillips, J A; Reeders, S T


    Autosomal dominant adult-onset polycystic kidney disease (ADPKD) is estimated to have an incidence of 1/1,000 and accounts for approximately 10% of all end-stage renal disease in the United States. While relatives are attractive as renal donors due to their availability and the improved transplant success associated with living-related donors, they may coincidentally be at risk for ADPKD. Accurate presymptomatic testing for at-risk potential donors is critical for both the donor and the recipient. We report here 2 families in which presymptomatic testing for ADPKD was accomplished by DNA linkage analysis on several potential renal donors prior to transplant. This resulted in the protection of both donors and recipients by preventing the transplantation of a kidney affected by ADPKD. Thorough counseling prior to DNA analysis (including discussion of accuracy and possible testing outcomes of presymptomatic diagnosis of ADPKD, diagnosis of noncarrier status, false paternity, and non-informative study) was essential to provide informed consent and preserve confidentiality within the family. Confidentiality for potential donors found presymptomatically to be affected (with a 94% or greater probability) was especially difficult to maintain.

  8. Low-grade proteinuria and microalbuminuria in renal transplantation.

    Halimi, Jean-Michel


    Nephrotic-range proteinuria has been known for years to be associated with poor renal outcome. Newer evidence indicates that early (1-3 months after transplantation) low-grade proteinuria and microalbuminuria (1) provide information on the graft in terms of donor characteristics and ischemia/reperfusion injury, (2) may occur before the development of donor-specific antibodies, (3) predict the development of diabetes and cardiovascular events, and (4) are associated with reduced long-term graft and patient survivals. Low-grade proteinuria and microalbuminuria are also predictive of diabetes, cardiovascular morbidity, and death in nontransplanted populations, which may help us to understand the pathophysiology of low-grade proteinuria or microalbuminuria in renal transplantation. The impact of immunosuppressive medications, including mammalian target of rapamycin inhibitors, on graft survival is still discussed, and the effect on proteinuria is crucial to the debate. The fact that chronic allograft rejection may exist as early as 3 months after renal transplantation indicates that optimal management of low-grade proteinuria or microalbuminuria should occur very early after transplantation to improve long-term renal function and the overall outcome of renal transplant recipients. The presence of low-grade proteinuria or microalbuminuria early after transplantation must be taken into account to choose adequate immunosuppressive and antihypertensive medications. Limited information exists regarding the benefit of therapeutic interventions to reduce low-grade proteinuria or microalbuminuria. Whether renin angiotensin blockade results in optimal nephroprotection in patients with low-grade proteinuria or microalbuminuria is not proven, especially in the absence of chronic allograft nephropathy. Observational studies and randomized clinical trials yield conflicting results. Finally, randomized clinical trials are urgently needed.

  9. The renal scan in pregnant renal transplant patients

    Goldstein, H.A.; Ziessman, H.A.; Fahey, F.H.; Collea, J.V.; Alijani, M.R.; Helfrich, G.B.


    With the greater frequency of renal transplant surgery, more female pts are becoming pregnant and carrying to term. In the renal allograft blood vessels and ureter may be compressed resulting in impaired renal function and/or, hypertension. Toxemia of pregnancy is seen more frequently than normal. Radionuclide renal scan monitoring may be of significant value in this high risk obstetrical pt. After being maintained during the pregnancy, renal function may also deteriorate in the post partum period. 5 pregnant renal transplant pts who delivered live babies had renal studies with Tc-99m DTPA to assess allograft perfusion and function. No transplanted kidney was lost during or after pregnancy as a result of pregnancy. No congenital anomalies were associated with transplant management. 7 studies were performed on these 5 pts. The 7 scans all showed the uterus/placenta. The bladder was always distorted. The transplanted kidney was rotated to a more vertical position in 3 pts. The radiation dose to the fetus is calculated at 0.024 rad/mCi administered. This study demonstrates the anatomic and physiologic alterations expected in the transplanted kidney during pregnancy when evaluated by renal scan and that the radiation burden may be acceptable in management of these pts.

    Fulminant hepatitis is fatal in most cases and timely liver transplantation is the only effective treatment.This study evaluates the survival outcomes of patients who underwent living-donor liver transplantation (LDLT)using right lobe liver grafts for fulminant liver failure due to hepatitis B infection.Nine cases of adult right lobe LDLT were performed in our department from September 2002 to August 2005 and the clinical and following-up data were reviewed.According to the pre-transplant Child-Pugh-Turcotte classification,the nine patients were classified as grade C.The model for end-stage liver disease (MELD) score of these patients ranged from 16 to 42.The principal complications before transplantation included abnormal renal function,hepatic coma of different degrees and alimentary tract hemorrhage.The main complications after transplantation included pulmonary infection in two cases,acute renal failure in three cases and transplantation-related encephalopathy in one case.No primary failure of vascular or biliary complications occurred.The one-year survival rate was 55.6%.There were no serious complications or deaths in donors.In general,it is extremely difficult to treat fulminant hepatitis by conservative regimen,particularly,in cases with rapid progresslon.Emergency adult living-donor liver transplantation is an effective treatment for fulminant hepatitis patients and is relatively safe for donors.

  11. Donor Kidney With Renal Cell Carcinoma Successfully Treated With Radiofrequency Ablation

    Christensen, S F; Hansen, Jesper Melchior


    BACKGROUND: The risk of donor-transmitted cancer is evident. CASE REPORT: We report the case of a 69-year-old woman who was transplanted with a kidney from a deceased donor. Four days after transplantation a routine ultrasound scan revealed a 3-cm tumor in the middle-upper pole of the allograft....... A biopsy showed the tumor to be papillary renal cell carcinoma. The patient was treated with radiofrequency ablation. This procedure was complicated by the development of a cutaneous fistula and open surgery was done with resection of an area of necrosis in the kidney and of the fistula. The maintenance.......04 mg/dL]). CONCLUSIONS: To the best of our knowledge, this is the first case in which a donor-transmitted tumor was diagnosed in the renal allograft only 4 days after transplantation and subsequently treated successfully with radiofrequency ablation....

  13. Imaging in Lung Transplantation: Surgical Considerations of Donor and Recipient.

    Backhus, Leah M; Mulligan, Michael S; Ha, Richard; Shriki, Jabi E; Mohammed, Tan-Lucien H


    Modifications in recipient and donor criteria and innovations in donor management hold promise for increasing rates of lung transplantation, yet availability of donors remains a limiting resource. Imaging is critical in the work-up of donor and recipient including identification of conditions that may portend to poor posttransplant outcomes or necessitate modifications in surgical technique. This article describes the radiologic principles that guide selection of patients and surgical procedures in lung transplantation.

    Mehdi Azami


    Full Text Available The impact of intestinal parasitic infection in renal transplant recipients requires careful consideration in the developing world. However, there have been very few studies addressing this issue in Iran. This study was conducted to determine the prevalence of intestinal parasitic infections in renal transplant recipients in Iran. Stool specimens from renal transplant recipients and control groups were obtained between June 2006 and January 2007. The samples screened for intestinal parasitic infections using direct smear, formalin-ether sedimentation, Sheather's flotation and modified Ziehl-Neelsen staining methods. Out of 150 renal transplant recipients, 33.3% (50, and out of 225 control group, 20% (45 were infected with one or more type of intestinal parasites. The parasites detected among patients included Entamoeba coli (10.6%, Endolimax nana (8.7%, Giardia lamblia (7.4%, Blastocystis spp. (4.7%, Iodamoeba butschlii (0.7%, Chilomastix mesnili (0.7% and Ascaris lumbricoides (0.7%. Multiple infections were more common among renal transplant recipients group (p < 0.05. This study highlights the importance of testing for intestinal parasites among Iranian renal transplant recipients. Routine examinations of stool samples for parasites would significantly benefit the renal transplant recipients by contributing to reduce severe infections.

  16. Successful Transplantation of a Split Crossed Fused Ectopic Kidney into a Patient with End-Stage Renal Disease

    Kristin L. Mekeel


    Full Text Available Potential donors with congenital renal anomalies but normal renal function are often overlooked because of a possible increase in technical difficulty and complications associated with the surgery. However, as the waiting list for a deceased donor kidney transplant continues to grow, it is important to consider these kidneys for potential transplant. This paper describes the procurement of a crossed fused ectopic kidney, and subsequent parenchymal transection prior to transplantation as part of a combined simultaneous kidney pancreas transplant. The transplant was uncomplicated, and the graft had immediate function. The patient is now two years from transplant with excellent function.

    Renal replacement therapy (RRT) resources are scarce in India, with wide urban-rural and interstate disparities. The burden of end-stage renal disease is expected to increase further due to increasing prevalence of risk factors like diabetes mellitus. Renal transplantation, the best RRT modality, is increasing in popularity, due to improvements made in public education, the deceased donor transplantation (DDT) programme and the availability of free and affordable transplant services in government hospitals and certain non-governmental philanthropic organizations. There are about 120000 haemodialysis patients and 10000 chronic peritoneal dialysis patients in India, the majority of them waiting for a donor kidney. Shortage of organs, lack of transplant facilities and high cost of transplant in private facilities are major barriers for renal transplantation in India. The DDT rate in India is now 0.34 per million population, among the lowest in the world. Infrastructural development in its infancy and road traffic rules not being strictly implemented by the authorities, have led to road traffic accidents being very common in urban and rural India. Many patients are declared brain dead on arrival and can serve as potential organ donors. The DDT programme in the state of Tamil Nadu has met with considerable success and has brought down the incidence of organ trade. Government hospitals in Tamil Nadu, with a population of 72 million, provide free transplantation facilities for the underprivileged. Public private partnership has played an important role in improving organ procurement rates, with the help of trained transplant coordinators in government hospitals. The DDT programmes in the southern states of India (Tamil Nadu, Kerala, Pondicherry) are advancing rapidly with mutual sharing due to public private partnership providing vital organs to needy patients. Various health insurance programmes rolled out by the governments in the southern states are effective in

  20. [Serum beta 2 microglobulin (beta 2M) following renal transplantation].

    Pacheco-Silva, A; Nishida, S K; Silva, M S; Ramos, O L; Azjen, H; Pereira, A B


    Although there was an important improvement in graft and patient survival the last 10 years, graft rejection continues to be a major barrier to the success of renal transplantation. Identification of a laboratory test that could help to diagnose graft rejection would facilitate the management of renal transplanted patients. PURPOSE--To evaluate the utility of monitoring serum beta 2M in recently transplanted patients. METHODS--We daily determined serum beta 2M levels in 20 receptors of renal grafts (10 from living related and 10 from cadaveric donors) and compared them to their clinical and laboratory evolution. RESULTS--Eight patients who presented immediate good renal function following grafting and did not have rejection had a mean serum beta 2M of 3.7 mg/L on the 4th day post transplant. The sensitivity of the test for the diagnosis of acute rejection was 87.5%, but the specificity was only 46%. Patients who presented acute tubular necrosis (ATN) without rejection had a progressive decrease in their serum levels of beta 2M, while their serum creatinine changed as they were dialyzed. In contrast, patients with ATN and concomitance of acute rejection or CSA nephrotoxicity presented elevated beta 2M and creatinine serum levels. CONCLUSION--Daily monitoring of serum beta 2M does not improve the ability to diagnose acute rejection in patients with good renal function. However, serum beta 2M levels seemed to be useful in diagnosing acute rejection or CSA nephrotoxicity in patients with ATN.

  1. Sequential renal and bone marrow transplants in a child with Fanconi anemia.

    Vincent, Carol L; Primack, William A; Hipps, John; Kasow, Kimberly A


    FA is an autosomal recessive disorder characterized by small stature and renal abnormalities. FA can lead to progressive bone marrow failure, myelodysplastic syndrome, or acute leukemia. Using a multidisciplinary team approach, we managed a 3-yr-old boy with FA who simultaneously developed renal and hematopoietic failure. Because renal function was insufficient to support the conditioning regimen for HCT, we performed a deceased donor renal transplant in December 2012 prior to HCT with the known risk of graft-versus-graft rejection of the donor kidney. Seven months later he underwent allogeneic HCT. He obtained myeloid engraftment on day +11 and peripheral blood chimerism demonstrated all donor by day +21. He developed asymptomatic CMV reactivation and despite antirejection medications, mild skin graft-versus-host disease. He has maintained excellent renal function and remains transfusion independent with full hematopoietic recovery. He has not experienced any renal rejection episodes nor developed donor-specific antibodies toward his renal donor. Peripheral blood chimerism remains completely HCT donor. He is clinically well, now greater than two and a half yr after renal transplant and two yr after HCT. The continuing close collaboration between the Pediatric Nephrology and Bone Marrow Transplant teams is a major factor in this successful outcome.

    Kidney transplantation is the optimal therapy for the majority of patients with end-stage renal disease. However, the cost and health outcomes of transplantation have not been assessed in a middle-income nation with a low volume of transplantation, such as Malaysia. This study used microcosting methods to determine the cost and health outcomes of living and deceased donor kidney transplantation in adult and pediatric recipients. The perspective used was from the Ministry of Health Malaysia. Cost-effectiveness measures were cost per life year (LY) and cost per quality-adjusted LYs. The time horizon was the lifetime of the transplant recipient from transplant to death. Records of 206 KT recipients (118 adults and 88 children) were obtained for microcosting. In adults, discounted cost per LY was US $8609(Malaysian Ringgit [RM]29 482) and US $13 209(RM45 234) for living-donor kidney transplant (LKT) and deceased donor kidney transplant (DKT), respectively, whereas in children, it was US $10 485(RM35 905) and US $14 985(RM51 317), respectively. Cost per quality-adjusted LY in adults was US $8826 (RM30 224) for LKT and US $13 592(RM46 546) for DKT. Total lifetime discounted costs of adult transplants were US $119 702 (RM409 921) for LKT, US $147 152 (RM503 922) for DKT. Total costs for pediatric transplants were US $154 841(RM530 252) and US $159 313(RM545 566) for the 2 categories respectively. Both LKT and DKT are economically favorable for Malaysian adult and pediatric patients with ESRD and result in improvement in quality of life.

  3. Imaging evaluation of potential donors in living-donor liver transplantation

[Department of Surgery, University of Alberta Hospital (Canada)


    Liver transplants, originally obtained from deceased donors, can now be harvested from living donors as well. This technique, called living-donor liver transplantation (LDLT), provides an effective alternative means of liver transplantation and is a method of expanding the donor pool in light of the demand and supply imbalance for organ transplants. Imaging plays an important role in LDLT programmes by providing robust evaluation of potential donors to ensure that only anatomically suitable donors with no significant co-existing pathology are selected and that crucial information that allows detailed preoperative planning is available. Imaging evaluation helps to improve the outcome of LDLT for both donors and recipients, by improving the chances of graft survival and reducing the postoperative complication rate. In this review, we describe the history of LDLT and discuss in detail the application of imaging in donor assessment with emphasis on use of modern computed tomography (CT) and magnetic resonance imaging (MRI) techniques.

    Adult-to-adult living donors and recipients were studied to characterize patterns of liver growth and identify associated factors in a multicenter study. Three hundred and fifty donors and 353 recipients in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) receiving transplants between March 2003 and February 2010 were included. Potential predictors of 3-month liver volume included total and standard liver volumes (TLV and SLV), Model for End-Stage Liver Disease (MELD) score (in recipients), the remnant and graft size, remnant-to-donor and graft-to-recipient weight ratios (RDWR and GRWR), remnant/TLV, and graft/SLV. Among donors, 3-month absolute growth was 676 ± 251 g (mean ± SD), and percentage reconstitution was 80% ± 13%. Among recipients, GRWR was 1.3% ± 0.4% (8 Graft weight was 60% ± 13% of SLV. Three-month absolute growth was 549 ± 267 g, and percentage reconstitution was 93% ± 18%. Predictors of greater 3-month liver volume included larger patient size (donors and recipients), larger graft volume (recipients), and larger TLV (donors). Donors with the smallest remnant/TLV ratios had larger than expected growth but also had higher postoperative bilirubin and international normalized ratio at 7 and 30 days. In a combined donor-recipient analysis, donors had smaller 3-month liver volumes than recipients adjusted for patient size, remnant or graft volume, and TLV or SLV (P = 0.004). Recipient graft failure in the first 90 days was predicted by poor graft function at day 7 (HR = 4.50, P = 0.001) but not by GRWR or graft fraction (P > 0.90 for each). Both donors and recipients had rapid yet incomplete restoration of tissue mass in the first 3 months, and this confirmed previous reports. Recipients achieved a greater percentage of expected total volume. Patient size and recipient graft volume significantly influenced 3-month volumes. Importantly, donor liver volume is a critical predictor

  6. Association of Live Donor Nephrectomy and Reversal of Renal Artery Spasm

    Jalal Azmandian


    Full Text Available Background: Kidney transplantation is the best treatment option for kidney failure. Major medical progress has been made in the field of renal transplantation over the last 40 years. The surgical procedure has been standardized and the complication rate is low. Overall, the outcome of renal transplantation is excellent and has improved over time. Vascular complications after renal transplantation are the most frequent type of complication following urological complications. Renal artery spasm (RAS following manipulation of renal artery is a common problem during live donor nephrectomy (LDN. The aim of this study was to determine whether or not it is necessary to wait for reverse of RAS and resumption of urinary flow before nephrectomy. Materials and Methods: In this clinical trial 16 cases of LDN who developed RAS during surgery received intra-arterial injection of 40 mg papaverine. In 8 cases surgery continued towards nephrectomy and in other 8 cases we waited for reverse of RAS. All analyses were performed using SPSS-11. Results: In both groups urinary flow started a few minutes (Mean, 12 min after declamping of transplanted kidney and normal renal consistency and color were achieved. There was no significant difference between urinary volume during 12 h after transplantation in two groups. Conclusion: The results showed that it might not be necessary to wait for reverse of RAS before LDN. Both patient (less anesthesia complications and hospital (less expenses will benefit from this time saving.

  7. Living donor kidney transplantation: "beauty and the beast"!

    Danovitch, Gabriel M


    The report by Terasaki and colleagues in 1995 that the outcomes of spousal and biologically unrelated transplants were essentially the same as for 1-haplotype matched living related transplants changed the course of clinical transplantation. This article, entitled metaphorically "Beauty and the Beast", describes the dramatic change in the practice of living donor transplantation that followed. In the ensuing two decades, biologically unrelated living donor transplantation became commonplace in the developed world and reached its apotheosis in cross-country living donor paired exchange programs that have made transplantation accessible to many whose donors were deemed "incompatible". Such exchanges can indeed be thought of as a "thing of beauty". Sadly, the same observation was abused to exploit vulnerable donors, and the "beast" in the form of transplant tourism became a feature of transplantation in the developing world. The responsibility of the transplant community to protect the welfare of living donors and their recipients and the key role of trust in the evaluation of living donors is discussed.

  8. Clipless management of the renal vein during hand-assist laparoscopic donor nephrectomy

    Rosenblatt Gregory S


    Full Text Available Abstract Background Laparoscopic live donor nephrectomy has become the preferred method of donor nephrectomy at many transplant centers. The laparoscopic stapling device is commonly used for division of the renal vessels. Malfunction of the stapling device can occur, and is often due to interference from previously placed clips. We report our experience with a clipless technique in which no vascular clips are placed on tributaries of the renal vein at or near the renal hilum in order to avoid laparoscopic stapling device misfires. Methods From December 20, 2002 to April 12, 2005, 50 patients underwent hand-assisted laparoscopic left donor nephrectomy (LDN at our institution. Clipless management of the renal vein tributaries was used in all patients, and these vessels were divided using either a laparoscopic stapling device or the LigaSureTM device (Valleylab, Boulder, CO. The medical and operative records of the donors and recipients were reviewed to evaluate patient outcomes. Results The mean follow-up time was 14 months. Of the 50 LDN procedures, there were no laparoscopic stapling device malfunctions and no vascular complications. All renal allografts were functioning at the time of follow-up. Conclusion Laparoscopic stapling device failure due to deployment across previously placed surgical clips during laparoscopic live donor nephrectomy can be prevented by not placing clips on the tributaries of the renal vein. In our series, there were no vascular complications and no device misfires. We believe this clipless technique improves the safety of laparoscopic donor nephrectomy.

    Reese, Peter P; Hwang, Hojun; Potluri, Vishnu; Abt, Peter L.; Shults, Justine; Amaral, Sandra


    Children receive priority in the allocation of deceased donor kidneys for transplantation in the United States, but because allocation begins locally, geographic differences in population and organ supply may enable variation in pediatric access to transplantation. We assembled a cohort of 3764 individual listings for pediatric kidney transplantation in 2005–2010. For each donor service area, we assigned a category of short (270 days) median waiting time and calculated the ratio of pediatric-...

    Kidney transplants with expanded criteria donor have been associated with improved patient survival compared to those who remain on dialysis. To compare renal function and survival of the kidney graft of deceased donor with expanded criteria and standard criteria over a year in a single transplant center. 255 kidney transplant recipients with deceased donor were included in the study between the years 2011 to 2013 and they were separated into two groups according to the type of donor (expanded criteria donor - ECD - and standard criteria donor - SCD). 231 deceased donor transplants (90.6%) were performed with standard criteria donor (SCD) and 24 (9.4%) with expanded criteria donor (ECD). There was no difference in the prevalence of delayed graft function - DGF - (62.9% vs. 70.8%; p = 0.44). Expanded criteria donor group had lower glomerular filtration rate (GFR) at the end of the 1st year (56.8 ± 26.9 vs. 76.9 ± 23.7; p = 0.001). Patient survival was significantly lower in the ECD group, but the graft survival was not different after death-censored analysis. The ECD group was associated with significantly lower levels of GFR during the first year of transplant and a lower patient survival at the 1st year when compared to the SCD. A aceitação dos rins com critério expandido de doação tem sido associada com melhor sobrevida do paciente em comparação àqueles que permanecem em terapia dialítica. Comparar a função renal e a sobrevida do enxerto renal de doador falecido critério expandido com os de doador falecido critério padrão ao longo de um ano em um único centro de transplantes. Foram incluídos 255 receptores de transplante renal com doador falecido, realizados entre os anos de 2011 a 2013, sendo divididos em dois grupos segundo o tipo de doador (critério expandido - DCE - ou padrão -DCP). Foram avaliados 231 receptores com doador critério ideal (90,6%) e 24 com doador critério expandido (9,4%). Não houve diferença na prevalência de fun

    A 20-year-old woman was admitted to an emergency hospital after ingesting 66 g of acetylsalicylic acid in a suicide attempt. Although she was treated with gastric lavage, oral activated charcoal, and intravenous hydration with sodium bicarbonate, her hepatic and renal function gradually deteriorated and serum amylase levels increased. Steroid pulse therapy, plasma exchange, and continuous hemodiafiltration did not yield any improvement in her hepatic or renal function, and she was transferred to our hospital for living donor liver transplantation. Nine days after drug ingestion, she developed hepatic encephalopathy: thus, we diagnosed the patient with acute liver failure with hepatic coma accompanied by acute pancreatitis due to the overdose of acetylsalicylic acid. Living donor liver transplantation was immediately performed using a left lobe graft from the patient's mother. Following transplantation, the patient's renal and hepatic function and consciousness improved, and she was discharged. In this report, we describe a rare case of acetylsalicylic acid-induced acute liver failure with acute hepatic coma and concomitant acute pancreatitis and acute renal failure, which were treated successfully with emergency living donor liver transplantation.

    Full Text Available Aim of study. The demonstration of our own experience in heart transplantation after valve reconstruction. Methods and results. From May 2012 to March 2013 3 mitral valve annuloplasties were performed to recipi- ents, requiring urgent HT and having extremely unfavorable prognosis of survival without HT. The recipients were classified as United Network for Organ Sharing (UNOS IB, and all of them were on inotropic support. In one case, HT was performed after reconstruction of rheumatic mitral stenosis, in two other cases – after dege- nerative mitral regurgitation. The technical aspects are reviewed of ex-vivo mitral and tricuspid valves repair with concomitant heart transplantation. All patients were discharged from the hospital having excellent postope- rative recovery. Conclusion. Taking into consideration the demonstrated satisfactory result of surveillance and presence of significant experience in performing of reconstructive valve surgery among no-HT cardiosurgical patients, an increase in the pool of suitable donor organs is expected due to the liberalization of the selection criteria and the possibility of the innovative valve reconstruction procedures ex vivo.

Therefore, the validity of disease-specific instruments to measure HQoL in renal transplant recipients, such as the Kidney Transplant Questionnaire (KTQ, needs further investigation. The objective of this study was to assess the concurrent validity of the KTQ in adult US renal transplant recipients using the well established SF-12 Health Survey version 2 (SF-12v2 as the comparison instrument. Methods: One hundred and fourteen renal transplant recipients met the following inclusion criteria for this study, ie, were at least 21 years of age, more than two years post-transplant, and receiving immunosuppressant therapy. Subjects were asked to complete a series of HQoL instruments, ie, the KTQ and the SF-12v2 (physical component summary [PCS-12] and mental component summary [MCS-12]. Descriptive statistics were calculated, and correlational analyses were conducted to examine the concurrent validity of the HQoL instruments. Results: Among 100 participants (87.7% response rate, the majority of participants were male (52%, had deceased donor transplants (63%, and received Medicare benefits (84%. PCS-12 was positively correlated with three of five KTQ subscales (P < 0.05, ie, KTQ-physical (r = 0.43, KTQ-fatigue (r = 0.42, and KTQ-uncertainty/fear (r = 0.2. MCS-12 was positively correlated

  17. Anesthesia for parturient with renal transplantation

    Beena K Parikh


    Full Text Available Management of successful pregnancy after renal transplantation is a unique challenge to nephrologist, obstetrician, and anesthesiologist, as these patients have altered physiology and are immune-compromised. We present the anesthetic management of three postrenal transplant patients scheduled for cesarean section. While conducting such cases, cardiovascular status, hematological status, and function of transplanted kidney should be assessed thoroughly. Side effects of immunosuppressant drugs and their interaction with anesthetic agents should be taken into consideration. Main goal of anesthetic management is to maintain optimum perfusion pressure of renal allograft to preserve its function.

    Trotter, J F; Wachs, M; Trouillot, T; Steinberg, T; Bak, T; Everson, G T; Kam, I


    The initial success of living donor liver transplantation (LDLT) in the United States has resulted in a growing interest in this procedure. The impact of LDLT on liver transplantation will depend in part on the proportion of patients considered medically suitable for LDLT and the identification of suitable donors. We report the outcome of our evaluation of the first 100 potential transplant recipients for LDLT at the University of Colorado Health Sciences Center (Denver, CO). All patients considered for LDLT had first been approved for conventional liver transplantation by the Liver Transplant Selection Committee and met the listing criteria of United Network for Organ Sharing status 1, 2A, or 2B. Once listed, those patients deemed suitable for LDLT were given the option to consider LDLT and approach potential donors. Donors were evaluated with a preliminary screening questionnaire, followed by formal evaluation. Of the 100 potential transplant recipients evaluated, 51 were initially rejected based on recipient characteristics that included imminent cadaveric transplantation (8 patients), refusal of evaluation (4 patients), lack of financial approval (6 patients), and medical, psychosocial, or surgical problems (33 patients). Of the remaining 49 patients, considered ideal candidates for LDLT, 24 patients were unable to identify a suitable donor for evaluation. Twenty-six donors were evaluated for the remaining 25 potential transplant recipients. Eleven donors were rejected: 9 donors for medical reasons and 2 donors who refused donation after being medically approved. The remaining 15 donor-recipient pairs underwent LDLT. Using our criteria for the selection of recipients and donors for LDLT gave the following results: (1) 51 of 100 potential transplant recipients (51%) were rejected for recipient issues, (2) only 15 of the remaining 49 potential transplant recipients (30%) were able to identify an acceptable donor, and (3) 15 of 100 potential living donor

  19. Preemptive Renal Transplantation-The Best Treatment Option for Terminal Chronic Renal Failure.

    Arze Aimaretti, L; Arze, S


    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with transplantation, 64% of our patients had no public support; however, 64% of them returned to work and got health insurance 2 months later. Full rehabilitation was achieved in all cases, including integration to the family, return to full-time work, school and university, sports, and reproduction. Immunosuppression consisted of 3 drugs, including steroids, cyclosporine, and azathioprine or mycophenolate. The cost in the 1st year, including patient and donor evaluation, surgery, immunosuppression, and follow-up, was $13,300 USD versus $22,320 for hemodialysis. We conclude that preemptive renal transplantation with renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

  1. Pediatric live-donor kidney transplantation in Mansoura Urology & Nephrology Center: a 28-year perspective.

    El-Husseini, Amr A; Foda, Mohamed A; Bakr, Mohamed A; Shokeir, Ahmed A; Sobh, Mohamed A; Ghoneim, Mohamed A


    Our objective was to evaluate our overall experience in pediatric renal transplantation. Between March 1976 and March 2004, 1,600 live-donor kidney transplantations were carried out in our center; 216 of the patients were 18 years old or younger (mean age 12.9 years). There were 136 male patients and 80 female patients. The commonest causes of end-stage renal disease (ESRD) were renal dysplasia (22%), nephrotic syndrome (20%), hereditary nephritis (16%), and obstructive uropathy (16%). Of the donors, 94% were one-haplotype matched and the rest were identical. Pre-emptive transplantation was performed in 51 (23%) patients. Triple-therapy immunosuppression (prednisone + cyclosporine + azathioprine) was used in 78.2% of transplants. Rejection-free recipients constituted 47.7%. Hypertension (62%) was the commonest complication. A substantial proportion of patients (48%) were short, with height standard deviation score (SDS) less than -1.88. The overall infection rate was high, and the majority (53%) of infections were bacterial. The graft survival at 1 year, 5 years and 10 years were 93.4%, 73.3% and 48.2%, respectively, while the patients' survival at 1, 5 and 10 years were 97.6%, 87.8% and 75.3%, respectively. Despite long-term success results of pediatric renal transplantation in a developing country, there is a risk of significant morbidity.

    Background Living donor kidney transplantation is becoming popular in China,whereas,in clinical situations,some kidney donors may be sub-optimal,namely marginal living donor.The present study aimed to evaluate the safety and efficacy of marginal living donor kidney transplantation in a Chinese single center.Methods Between January 2001 and December 2009,888 kidney transplantations were performed in our center; 149were living donor kidney transplantations.The living donors and recipients were followed up regularly after the operation.Of the living donors,30 donors were marginal,who were older than 60 years or suffered from kidney anomaly or some benign diseases.Among the non-marginal living kidney transplantations,58 donors and recipients had complete perioperative and follow-up data.We compared the marginal and non-marginal living donor kidney transplantations with regard to donor age,follow-up period,donor's serum creatinine at the last follow-up,recipient's serum creatinine at the last follow-up,and graft survival at the last follow-up.Results The mean age of donors in the marginal and non-marginal living donors were (55±9) (37-66) and (43±12) (30-59) years.The mean follow-up times of the marginal and non-marginal groups were (26.4±13.4) months and (28.8±14.8)months.The donor and recipient serum creatinine levels at the last follow-up were (1.16±0.20) mg/dl and (1.30±0.24) mg/dl in the marginal group,and (1.12±0.32) mg/dl and (1.34±0.32) mg/dl in the non-marginal group.Three recipients in the marginal group and five recipients in the non-marginal group had acute rejection episodes during the first year.Actuarial 3-year graft survival was 96.7% in the marginal group and 100% in the non-marginal group.No significant differences were detected between the two groups with regard to these data.Conclusion Utilization of highly selective marginal living donors can be a safe,feasible,and effective way for the treatment of patients with end stage renal disease.

  3. Colovesical Fistula After Renal Transplantation: Case Report.

    Imafuku, A; Tanaka, K; Marui, Y; Sawa, N; Ubara, Y; Takaichi, K; Ishii, Y; Tomikawa, S


    Colovesical fistula is a relatively rare condition that is primarily related to diverticular disease. There are few reports of colovesical fistula after renal transplantation. We report of a 53-year-old man who was diagnosed with colovesical fistula after recurrent urinary tract infection, 5 months after undergoing cadaveric renal transplantation. Laparoscopic partial resection of the sigmoid colon with the use of the Hartmann procedure was performed. Six months after that surgery, there was no evidence of recurrent urinary tract infection and the patient's renal graft function was preserved. Physicians should keep colovesical fistula in mind as a cause of recurrent urinary tract infection in renal transplant recipients, especially in those with a history of diverticular disease.

  4. Simultaneous pancreas–kidney transplant for type I diabetes with renal failure: Anaesthetic considerations

    Lakshmi Kumar


    Full Text Available Pancreatic grafts have been successfully used in patients with diabetes and are combined with kidney transplantation in patients with renal failure. The propagation of awareness in organ donation in India has increased the donor pool of transplantable organs in the last few years making multi visceral transplants feasible in our country. We present the anaesthetic management of a 32-year-old male with diabetes mellitus and end-stage renal failure who was successfully managed with a combined pancreas and kidney transplantation.

    In the field of pediatric living donor liver transplantation, the indications for apheresis and dialysis, and its efficacy and safety are still a matter of debate. In this study, we performed a retrospective investigation of these aspects, and considered its roles. Between January 2008 and December 2010, 73 living donor liver transplantations were performed in our department. Twenty seven courses of apheresis and dialysis were performed for 19 of those patients (19/73; 26.0%). The indications were ABO incompatible-liver transplantation in 11 courses, fluid management in seven, acute liver failure in three, renal replacement therapy in two, endotoxin removal in two, cytokine removal in one, and liver allograft dysfunction in one. Sixteen courses of apheresis and dialysis were performed prior to liver transplantation for 14 patients. The median IgM antibody titers before and after apheresis for ABO blood type-incompatible liver transplantation was 128 and eight, respectively (P apheresis and dialysis were performed post liver transplantation for 10 patients. The median PaO2/FiO2 ratio before and after dialysis for fluid overload was 159 and 339, respectively (P apheresis and dialysis occurred. The 1-year survival rate of the patients was 100%. Apheresis and dialysis in pediatric living donor liver transplantation are effective for antibody removal in ABO-incompatible liver transplantation, and fluid management for acute respiratory failure.

  6. Risk Factors for Hypertension After Living Donor Kidney Transplantation in Korea: A Multivariate Analysis.

    Yu, H; Kim, H S; Baek, C H; Shin, E H; Cho, H J; Han, D J; Park, S K


    Post-transplantation hypertension is very common and is associated with cardiovascular complications and poor graft survival in kidney transplant recipients. This study aimed to identify risk factors for hypertension after living donor kidney transplantation. We retrospectively analyzed patients who underwent renal transplantation between January 2009 and April 2012. Hypertension was defined as the use of antihypertensive medications at 12 months post-transplantation. Student t test and chi-squared test were performed for univariate analysis. Logistic regression analysis was performed for multivariate analysis. Five-hundred thirty-nine patients were enrolled in the analyses. The rate of antihypertensive medication use was 67% at 12 months. In multivariate analysis, male gender (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.55-4.61), pretransplantation hypertension (OR, 4.65; 95% CI, 2.14-10.11), donor hypertension (OR, 3.23; 95% CI, 1.05-9.96), high body mass index (BMI; OR, 1.21; 95% CI, 1.12-1.29), and use of cyclosporine (OR, 2.05; 95% CI, 1.28-3.27) were associated with post-transplantation hypertension. These data show that male recipient, hypertension before transplantation, donor hypertension, high BMI, and cyclosporine use were independent factors associated with hypertension. It would be useful to predict and prevention the hypertension after kidney transplantation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Introdução: A transplantação renal é a terapêutica de eleição na criança com doença renal crónica terminal, evidenciando impacto positivo na sobrevida e qualidade de vida dos doentes. Não é, no entanto, isenta de complicações, algumas com importante morbilidade. Os autores pretendem caracterizar o perfil de complicações pós transplantação renal em doentes pediátricos (até 18 anos).Material e Métodos: Análise retrospectiva dos doentes submetidos a transplantação renal e seguidos na Unidade de Nefrologia Pediátrica entre Setembro de 1995 e Agosto de 2010. Dados obtidos dos processos clínicos: características demográficas, etiologia da doença renal crónica terminal, terapêutica de substituição renal, mortalidade e perda de enxertos, complicações cirúrgicas, infecciosas e não infecciosas (rejeição aguda e crónica, recidiva da doença de base, alterações metabólicas e factores de risco cardiovascular). Análise estatística descritiva simples.Resultados: Foram incluídas 78 crianças transplantadas (48,7% sexo masculino), com idade mediana à data da transplantaçãorenal de 12 anos (2 - 18). A maioria fez previamente diálise peritoneal: 49 (62,6%). Cinco doentes (6,4%) foram transplantados sem diálise prévia. A mediana do tempo de seguimento após transplante foi 37,5 meses (1 - 169). As principais etiologias de doença renal crónica terminal foram: uronefropatias (41%) e glomerulopatias (28,2%). As complicações infecciosas ocorreram em 74,4%; infecçõesvirais em 56,4%, sendo a mais prevalente a infecção citomegalovírus (39,7%); infecções bacterianas em 53,8% (na maioria infecções urinárias em doentes urológicos). Outras complicações: 1) factores de risco para doença cardiovascular: hipertensão arterial em 85,9%; dislipidémia em 16,7% e diabetes de novo em 7,7%; 2) episódios de rejeição aguda em 32,1% e nefropatia crónica do enxerto em 17,9%; 3) complicações relacionáveis com a cirurgia em 16

  9. Pulmonary Infection In Renal Transplant Recipients

    Rassulineiad M


    Full Text Available Renal transplantation is ideal treatment of chronic renal failure. Pulmonary infection is a common and serious post transplant infection requiring hospitalization and is associated with high mortality. Increased susceptibility to infection is due to a decrease in the patients' immunological response caused by immunosuppression through drug administration, and by other influences."nMaterials and Methods: This study was case series and prospective, from July 2001 to July 2002 in Imam Khomeini hospital of Tehran."nResults: 164 renal transplant recipients were studied, 14 patients (8.5% had pulmonary infection, 11 of them (78.6% were female and 3 (21.4% were male. The mean age of them was 42.6 years. The patients were followed up for 9 to 12 months. All patients were on triple immunosuppressive regimens. The interval between transplantation and the appearance of pneumonia was 2 months to 10 years. The time of beginning infection in 3 cases (21.4% was between 1 to 6 months post transplantation, 11 cases (78.6% were occurred beyond 6 months after transplantation. In 7 cases (50%, pulmonary infection was occurred during first year after transplantation. None of the 14 patients developed pulmonary infection in first month after transplantation. BAL were used in 6 cases (42.8% of pulmonary infection, and organism were detected in 5 of them (83.3%. The most common clinical feature was fever. Six cases were due to mycobacterium tuberculosis (42.9%, this organism was the most common ethiology of pneumonia. In this study tuberculosis was seen in 3.6% of renal transplant recipients. One patient had pulmonary mucormycosis. All patients with pulmonary TB were cured, and other cases with unknown case, were cured with empirical treatment."nConclusion: Our finding indicate the invasive diagnostic procedures are required in order to earlier and reliable diagnosis and then better outcome of transplantation."n"n"n"n"n"n"n

  11. Renal transplantation in Nepal: The first year′s experience

    Chalise Pawan


    Full Text Available A successful renal transplantation service was started in Nepal at the Tribhuvan Univer-sity Teaching Hospital in August 2008, and a continuing regular service is being provided currently to needy people. We report here our experience in thirty five end stage renal disease patients who re-ceived kidneys from close relatives during a one year period. The mean age of donors was 46.7 years. Seventeen (49% donations were from parents, 13 (37% from spouses, four (11% between siblings and one (3% between mother and daughter in law. Although the left kidney was given preference, right sided donor nephrectomy was needed in five (14% cases. Six (17% donors had minor post-operative problems. The mean age of recipients was 33.2 years, four (11% of whom had pre-emptive renal transplantation. Recipients were immunosuppressed with dacluzimab, prednisolone, mycophena-late, and cyclosporine or tacrolimus. The average time taken for graft implantation was 137 minutes. The mean cold ischemia time and second warm ischemia time were 133 and 36 minutes respectively. Four (11% patients developed urinary tract infection, three (9% had significant hematuria, one (3% developed a peri-transplant abscess, and one (3% had ureteric ischemia and urine leak which required re-exploration in the early post-operative period. Four patients (11% developed acute rejection of which three were cell- mediated rejection and one was antibody-mediated. There were two (6% deaths, one due to transplant-related sepsis and the other due to subarachnoid hemorrhage following rupture of a posterior communicating artery aneurysm. No kidney has been lost otherwise.

  12. Opportunistic infections in a renal transplant recipient

    Vijaya V. Mysorekar


    Full Text Available With the present progress in transplantation procedures, there is an improvement in patient and allograft survival. However, the immunosuppression necessary to sustain the allograft predisposes these transplant recipients to infection, which is now a significant cause of morbidity and mortality. We describe a case of a 30-year-old renal transplant recipient with two opportunistic infections, namely, primary cutaneous aspergillosis and intestinal tuberculosis, with terminal enterococcal pleuritis and peritonitis. Control of the degree of immunosuppression, and prompt recognition and treatment of infection are vital for successful organ transplantation.

  13. [Cost of a renal transplant: medico-economic analysis of the amount reimbursed by the French national health program to finance renal transplantation].

    Sainsaulieu, Yoël; Sambuc, Cléa; Logerot, Hélène; Bongiovanni, Isabelle; Couchoud, Cécile


    Successful organ transplantation relies on several ancillary activities such as the identification of a compatible donor, organ allocation and procurement and the coordination of the transplant process. No existing study of the overall costs, in France, of these additional transplantation activities could be identified. This study determines the total additional costs of ancillary transplantation activities by comparing the costs of kidney transplantations with living donors against those using deceased donors. The data used are drawn from the 2013 public healthcare tariff calculations, PMSI recorded activity and transplant activity in 2012 as assessed and reported by the Agence de la biomédecine. The results show that, in 2012, additional transplant costs varied from 13835.44 € to 20050.67 € for a deceased donor and were 13601.66 € for a living donor. In conclusion, this study demonstrates that all the costs covered by National Health Insurance need to be taken into account in the economic impact evaluation of renal transplantation and during the development of this national priority activity.

    Kuvacić, I; Sprem, M; Skrablin, S; Kalafatić, D; Bubić-Filipi, L; Milici D


    To correlate pregnancy outcome with complications in pregnancy and transplantation-to-pregnancy interval in renal transplant recipients in Croatia. Data on 23 pregnancies after prepregnancy stabilization of blood pressure and normalization of graft function were retrospectively analyzed. The mean interval between transplantation and conception was 3.1 years. Primary renal disease was chronic glomerulonephritis in 7, chronic pyelonephritis in 7 and agenesis of right kidney and stenosis of left renal artery in 1 patient. There were 10 term and 5 preterm deliveries, 6 induced and 2 spontaneous abortions. The mean gestational age was 38.1 weeks and the mean newborn birthweight was 3015 g. The prematurity rate was 21.7%. Patients with arterial hypertension in pregnancy, elevated serum creatinine level and bacteriuria, as well as those with conception occurring less than 2 years after transplantation, had a higher rate of therapeutic and spontaneous abortions, preterm deliveries and low birth weight infants. The interval between transplantation and conception, as well as allograft function during pregnancy, seem to be of great importance for successful obstetric outcome in renal transplant patients.

    Zhou Shoujun; Li Enchun; He Jun; Weng Guobin; Yuan Hexing; Hou Jianquan


    Background Rat renal transplantation is an essential experimental model and requires greater microsurgical skills.Thus,training novices to perform quick and reliable microvascular anastomosis is of vital importance for rat renal transplantation.In this study,we developed and evaluated a staged microvascular anastomosis training program for novices,harvesting and transplanting both kidneys from one rat donor.Methods Five trainees without any prior microsurgical experience underwent a training program in which the goals were staged according to difficulty.Each trainee had to achieve satisfactory results as evaluated by a mentor before entering the next stage.Rat renal transplantation was accomplished by end-to-end technique with a bladder patch.In the intensive rat renal transplantation stage,the trainees required an average of 20 independent attempts at isotransplantation as final training assessment.Results After 2 months of intensive practice,all trainees had achieved stable and reproducible rat renal transplantation,with a satisfactory survival rate of 85.9% at postoperative Day 7.The total mean operative time was 78.0 minutes and the mean hot ischemia time was 26.2 minutes.With experience increasing,the operative time for each trainee showed a decreasing trend,from 90-100 minutes to 60-70 minutes.After 20 cases,the mean operative time of the trainees was not statistically significantly different from that of the mentor.Conclusion Harvesting and transplanting both kidneys from one rat donor after a staged microvascular anastomosis training program is feasible for novices without any prior microsurgical skills.

  16. Lung Cancer in Renal Transplant Recipients

    Jozicic Mirela


    Full Text Available Introduction. Although the incidence of malignancy has increased after solid organ transplantation, data on lung cancer in this group of patients is scarce. The aim of this study was to determine clinical characteristics and outcome of patients who developed lung cancer after renal transplantation. Methods. Among a cohort of 1658 patients who received a transplant at our institution and were followedup between 1973 and 2014, five patients developed lung cancer. We analyzed risk factors, transplantation characteristics, treatment options and survival. Results. Lung cancer was diagnosed in 5 patients (0.3%. Time to diagnosis after the transplant procedure ranged from 26 to 156 months (mean 115 months. All of them had a smoking history. Tumors were classified as IIB (20%, IIIA (40%, and IV (40%. Histological types included adenocarcinoma (80% and there was one case of sarcomatoid carcinoma (20%. One patient had concomitant thyroid papillary carcinoma. Radiotherapy was applied in 2 patients, 2 underwent chemotherapy (erlotinib and combination of carboplatinum and etopozide in one patient each, and 2 died within one month after the diagnosis from disseminated malignant disease. Patients with stage IIIA survived 14 and 24 months after the diagnosis. The patient with sarcomatoid cancer underwent thoracotomy with a complete resection, lost his graft function and died 7 months after the diagnosis. Conclusion. Lung cancer is relatively rare malignancy in renal transplant recipients, but associated with high mortality. Smoking is a significant risk factor, thus smoking cessation should be promoted among renal transplant recipients, as well as regular screening for lung cancer.

  18. Chronic Renal Transplant Rejection and Possible Anti-Proliferative Drug Targets.

    Bhatti, Adnan Bashir; Usman, Muhammad


    The global prevalence of renal transplants is increasing with time, and renal transplantation is the only definite treatment for end-stage renal disease. We have limited the acute and late acute rejection of kidney allografts, but the long-term survival of renal tissues still remains a difficult and unanswered question as most of the renal transplants undergo failure within a decade of their transplantation. Among various histopathological changes that signify chronic allograft nephropathy (CAN), tubular atrophy, fibrous thickening of the arteries, fibrosis of the kidney interstitium, and glomerulosclerosis are the most important. Moreover, these structural changes are followed by a decline in the kidney function as well. The underlying mechanism that triggers the long-term rejection of renal transplants involves both humoral and cell-mediated immunity. T cells, with their related cytokines, cause tissue damage. In addition, CD 20+ B cells and their antibodies play an important role in the long-term graft rejection. Other risk factors that predispose a recipient to long-term graft rejection include HLA-mismatching, acute episodes of graft rejection, mismatch in donor-recipient age, and smoking. The purpose of this review article is the analyze current literature and find different anti-proliferative agents that can suppress the immune system and can thus contribute to the long-term survival of renal transplants. The findings of this review paper can be helpful in understanding the long-term survival of renal transplants and various ways to improve it.

  19. Biopsy Induced Arteriovenous Fistula and Venous Stenosis in a Renal Transplant

    Sridhar R. Allam


    Full Text Available Renal transplant vein stenosis is a rare cause of allograft dysfunction. Percutaneous stenting appears to be safe and effective treatment for this condition. A 56-year-old Caucasian female with end stage renal disease received a deceased donor renal transplant. After transplant, her serum creatinine improved to a nadir of 1.2 mg/dL. During the third posttransplant month, her serum creatinine increased to 2.2 mg/dL. Renal transplant biopsy showed BK nephropathy. Mycophenolate was discontinued. Over the next 2 months, her serum creatinine crept up to 6.2 mg/dL. BK viremia improved from 36464 copies/mL to 15398 copies/mL. A renal transplant ultrasound showed lower pole arteriovenous fistula and abnormal waveforms in the renal vein. Carbon dioxide (CO2 angiography demonstrated severe stenosis of the transplant renal vein. Successful coil occlusion of fistula was performed along with angioplasty and deployment of stent in the renal transplant vein. Serum creatinine improved to 1.5 mg/dL after.

    陶舒敏; 张喆; 吉秋; 孔祥; 张龙江


    Objective To discuss the left renal vein anatomy at multi-detector row CT and the implications for living renal transplantation.Methods The left renal vein anatomy and the branches in79 living renal transplantation donors who underwent contrast-enhanced CT angiography were analyzed retrospectively in this study. Maximum intensity projection, curve planar reformation and volume renderings were used for displaying the left renal vein anatomy. Anomalies of left renal vein and branches were recorded and classified.Results Left renal veins were all visualized on late arterial and venous phase CT images in all subjects. There were one case of circumaortic renal vein(n=1) and one case of left inferior vena cava(n=1).0 or1 adrenal vein,0 to2 lumbar veins and0 to 2 gonadal veins were found in each donor.Conclusion Among the left renal vein branches, the number of lumbar vein varied more frequently,multiple gonadal veins were detected in some subjects.

  1. Renal transplantation in a child with thrombosed inferior vena cava

    Surjeet Kumar


    Full Text Available The external iliac vein is commonly used in renal transplantation for vascular anastomosis of the allograft renal vein. However, there are rare instances when the transplant surgeon may encounter thrombosis of the ilio-caval vein during surgery, making renal transplantation a challenge. Often, these patients are considered unsuitable for renal transplantation. We report a case of thrombosis of the inferior vena cava in an asymptomatic pediatric patient in whom the splenic vein was used, at transplantation, for venous drainage. This case highlights that pre-operative Doppler screening should be performed in all potential renal transplant recipients.

  2. Outcome of Single Kidney Transplant From Pediatric Donors Younger Than 5 Years of Age After Cardiac Death in China: A Single Center Experience.

    Wang, Yaomin; Lv, Junhao; Xie, Wenqing; Huang, Hongfeng; Peng, Wenhan; Wu, Jianyong; Chen, Jianghua


    This study was conducted to evaluate the outcomes of single kidney transplant from pediatric donors in China younger than 5 years old after cardiac death. We retrospectively reviewed single renal transplants from pediatric donors of cardiac death between January 2012 and June 2013 at the First Affiliated Hospital of Zhejiang University, China. Eleven recipients received single kidney transplant from 6 pediatric donors of cardiac death donors at our center (aged, transplant. No episodes of acute rejection occurred. No vascular thrombosis or stenosis after ureteroneocystostomy was seen. One patient had urine leakage on the eighth day after transplant, and was cured through a ureter reimplantation. The graft size increased significantly the first month after transplant compared with that recorded immediately after reperfusion (P = .011). The 1-year patient/graft survival was 100%. Use of single kidney from pediatric donors after cardiac death (aged, < 5 y) is a safe and effective procedure and can greatly expand the donor pool.

  3. Strongyloides stercoralis transmission by kidney transplantation in two recipients from a common donor.

    Roseman, D A; Kabbani, D; Kwah, J; Bird, D; Ingalls, R; Gautam, A; Nuhn, M; Francis, J M


    Strongyloides stercoralis hyperinfection in an immunocompromised host has a high mortality rate but may initially present with nonspecific pulmonary and gastrointestinal symptoms. Donor-derived S. stercoralis by kidney transplantation is an uncommon diagnosis and difficult to prove. We report two renal allograft recipients on different immunosuppressive maintenance regimens that developed strongyloidiasis after transplantation from the same donor. Recipient 1 presented with a small bowel obstruction. Larvae were demonstrated on a duodenal biopsy and isolated from gastric, pulmonary, and stool samples. Serologic testing for S. stercoralis was negative at a referral laboratory but positive at the Centers for Disease Control. The patient's hospital course was complicated by a hyperinfection syndrome requiring subcutaneous ivermectin due to malabsorption. Recipient 1 survived but the allograft failed. Recipient 2 had larvae detected in stool samples after complaints of diarrhea and was treated. On retrospective testing for S. stercoralis, pretransplant serum collected from the donor and Recipient 1 was positive and negative, respectively. Donor-derived strongyloidiasis by renal transplantation is a preventable disease that may be affected by the immunosuppressive maintenance regimen. Subcutaneous ivermectin is an option in the setting of malabsorption. Finally, routine screening for S. stercoralis infection in donors from endemic areas may prevent future complications.

  4. Renal-sparing strategies in cardiac transplantation

    Gustafsson, Finn; Ross, Heather J


    PURPOSE OF REVIEW: Renal dysfunction due to calcineurin inhibitor (CNI) toxicity is a major clinical problem in cardiac transplantation. The aim of the article is to review the efficacy and safety of various renal sparing strategies in cardiac transplantation. RECENT FINDINGS: Small studies have...... documented that late initiation of CNI is safe in patients treated with induction therapy at the time of transplantation. Use of mycophenolate is superior when compared with azathioprine to allow for CNI reduction. More substantial reduction in CNI levels is safe and effective with the introduction...... of sirolimus or everolimus. However, studies that use very early CNI discontinuation have found an increased risk of allograft rejection, and this strategy requires further study before it can be routinely recommended. CNI discontinuation late after cardiac transplantation seems more effective than CNI...

  5. Proteinuria in Egyptian renal transplant recipients

    Essam Khedr


    Full Text Available To evaluate the prevalence, risk factors, possible etiology, prognosis and management of proteinuria in renal transplant recipients, we studied 435 adult renal transplant recipient patients randomly selected from our center; 394 patients were reviewed retrospectively and 41 patients were followed-up prospectively for a period of one year. The patients were classified into three groups according to the results of urinalysis and spot urinary albumin creatinine ratio: Group A patients with normoalbuminuria; Group B patients with microalbuminuria; and Group C patients with macroalbuminuria. Persistent post-transplantation proteinuria was detected in 125 (28.8% patients. The etiology of post-transplantation proteinuria included chronic allograft dysfunction in 44 (35.2% patients, acute rejection in 40 (32% patients, transplant glomerulopathy in eight (6.4% patients, glomerular disease in 16 (12.8% patients and other etiology in 17 (13.6% patients. Proteinuric patients demonstrated significantly lower graft survival rates than did those without proteinuria (48.3% versus 51.7%, respectively; P = 0.017; Risk Ratio = 0.403; 95% confidence interval 0.188-0.862. We conclude that proteinuria is prevalent after kidney transplant in our population, and that it is most commonly associated with chronic allograft nephropathy, transplant glomerulopathy, glomerulonephritis and acute rejection. Post-transplant proteinuria is associated with decreased allograft survival.

  6. Quality of life after liver transplantation with old donor graft

    Maria José Nascimento Flor


    Full Text Available Objective: to compare the quality of life of liver transplant patients who received liver from donor aged ≤60 or >60 years old. Methods: a prospective study with a sample of 141 recipients from liver donors aged equal to or less than 60 years and recipients of elderly donor liver, in a reference center. Authors used a tool for identification and the Short Form-36. The Student-t and Mann-Whitney tests were applied for comparison between groups. Results: there were higher levels of quality of life with a statistically significant difference: Group A in social aspect (p=0.02 and Group B >50 months of transplantation (p=0.05 in physical component summary. Conclusion: the quality of life of liver receptors from older donor livers was similar to those who received a graft from younger donors in most dimensions. Transplanting time had a positive impact on the quality of life of elderly recipients.

  7. Organ Transplants from Living Donors – Halachic Aspects

    Mordechai Halperin


    Full Text Available This manuscript is a survey of the halachic attitudes toward organ transplant procedures from a living donor which can be defined as life-saving procedures for the recipient or at least life-prolonging procedures. Three fundamental problems concerning the halachic aspects of such transplantation are discussed in detail: the danger to the donor, donation under coercion, and the sale of organs and tissues. The terms “halacha” and “Jewish law” are defined in the introduction.

  8. Urolithiasis in renal transplantation: Diagnosis and management

    Elisa Cicerello


    Full Text Available Obiectives: To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. Patients and Methods: From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10% of them developed urinary calculi and were referred at our institution. Their mode of presentation, investigation and treatment were recorded. Results: Seven had renal and 3 ureteral calculi. Urolithiasis was incidentally discovered on routine ultrasound in 6 patients, 1 presented with oliguria, 1 with anuria and acute renal failure and in 2 urolithiasis was found at removal of the ureteral stent. Nephrostomy tube was placed in 5 patients. Hypercalcemia with hyperparathyroidism (HPT was present in 5 patients and hyperuricemia in 3. Two patients were primary treated by shock wave lithotripsy (SWL and one of them was stone-free after two sessions. Two patients, one with multiple pielocaliceal calculi and the other with staghorn calculus in the lower calyx, were treated with percutaneous nephrolitothotomy (PCNL. Three patients were treated by ureteroscopy (URS and in one of them two treatments were carried out. One patient had calculus impacted in the uretero-vesical anastomosis and surgical ureterolithotomy with re-do ureterocystoneostomy was performed after failure of URS. Two patients with calculi discovered at removal of the ureteral stent were treated by URS. Conclusions: The incidence of urolithiasis in renal transplantation is uncommon. In the most of patients the condition occurs without pain. Metabolic anomalies and medical treatment after renal transplantation may cause stone formation. Advancements in endourology and interventional radiology have influenced the management of urolithiasis that can be actually treated with a minimal incidence of risk for the renal allograft.

  9. Renal transplantation using external continent urinary diversion.

    Lucon, A M; Sabbaga, E; Ianhez, L E; Chocair, P R; Pestana, J O; Arap, S


    A 29-year-old man born with bladder exstrophy presented with end stage renal failure many years after ileal conduit diversion. Bilateral nephrectomy and continent external urinary diversion were performed, and 1.5 months later a cadaveric kidney was grafted into the right iliac fossa. The patient was well at 18 months with a serum creatinine level of 1.2 mg./dl. and he was completely dry with 4 or 5 daily catheterizations. Although followup is still short, renal transplantation with drainage into an external continent urinary diversion permits excellent quality of life and good renal function. Therefore, this alternative is worth consideration whenever other reconstructive alternatives are not possible in candidates for renal transplantation.

  10. Cutaneous histoplasmosis in renal transplant recipients.

    Sun, N Z; Augustine, J J; Gerstenblith, M R


    Cutaneous histoplasmosis is a rare entity, although it can be seen in a substantial portion of renal transplant recipients with disseminated disease. The prognosis of disseminated disease is worse than isolated cutaneous involvement, and significant delays in diagnosis are reported. We reviewed reports of cutaneous histoplasmosis with and without dissemination in the setting of renal transplantation to examine incidence, timing of diagnosis, clinical features, and prognosis. Remarkable morphologic variability and the non-specific appearance of skin findings suggest that tissue culture is required for definitive diagnosis. Cutaneous lesions represent an easily accessible source for early diagnosis.

  11. Brucellosis in a renal transplant recipient.

    Ting, I W; Ho, M W; Sung, Y J; Tien, N; Chi, C Y; Ho, H C; Huang, C C


    Brucellosis is one of the most common systemic zoonotic diseases transmitted by consumption of unpasteurized dairy products or by occupational contact with infected animals. Brucellosis is rare in renal transplant recipients. Only 3 cases have been reported in the literature. We report a case of brucellosis with hematologic and hepatobiliary complications in a patient 3 years after renal transplantation. The mean time from transplantation to the diagnosis of brucellosis in these 4 reported patients was 5.1 years (range 17 months to 13 years). All patients had fever and constitutional symptoms, and all attained clinical cure after combination antibiotic therapy. Given the small number of patients, further study is needed to identify the characteristics of brucellosis in renal transplant recipients. Drug interactions and acute renal failure developed in our patient during antibiotic treatment. Therefore, we should monitor the levels of immunosuppressive agents frequently. Several studies have shown in vitro susceptibilities of Brucella melitensis to tigecycline. In our patient, fever finally subsided after tigecycline administration. The minimum inhibitory concentration of tigecycline using Etest was 0.094 μg/mL. Tigecycline may be a potential option for treatment of brucellosis in the setting of transplantation.

  12. Dynamic renal scintigraphic estimation of deceased donor kidneys in a rat model

    Huseyin Aydin Mitil


    Full Text Available At present a large number of the renal transplantations are being performed from the deceased donors. The success of these transplantations depends on the viability of the deceased donor kidneys. The aim of this study was to investigate the reliability of scintigraphic estimation of function of deceased donor kidneys by comparing the histopathologic and scintigraphic findings. Ten rats were included in the study (2–3 months old, 250–300 g, all male. Control scintigraphy was performed to all the rats by injection of 37 MBq Tc-99m DTPA from the tail vein in a dynamic manner. Brain death of the rats was achieved by inflation of a Fogartys catheter in the cranial cavity. Immediately, after brain death confirmation, dynamic renal scintigraphy was performed with the same parameters of control scintigraphy. In the comparison of scintigraphies obtained in the before and just after brain death period, there was impairment of tubular functions, concentration and excretion functions in the postbrain death period. In the immediate postbrain death period, there was a significant elevation in the glomerular filtration rate and time to maximum concentration values. In the histopathological evaluation of the kidney samples in the postbrain death period, there were definitive findings of tubular impairment. Dynamic renal scintigraphy also demonstrated definite impairment of tubular system and tubular functions in the deceased donor kidneys. This could explain the reason of the increased frequency of acute tubular necrosis seen among deceased donor kidneys.

  13. Geographic determinants of access to pediatric deceased donor kidney transplantation.

    Reese, Peter P; Hwang, Hojun; Potluri, Vishnu; Abt, Peter L; Shults, Justine; Amaral, Sandra


    Children receive priority in the allocation of deceased donor kidneys for transplantation in the United States, but because allocation begins locally, geographic differences in population and organ supply may enable variation in pediatric access to transplantation. We assembled a cohort of 3764 individual listings for pediatric kidney transplantation in 2005-2010. For each donor service area, we assigned a category of short (270 days) median waiting time and calculated the ratio of pediatric-quality kidneys to pediatric candidates and the percentage of these kidneys locally diverted to adults. We used multivariable Cox regression analyses to examine the association between donor service area characteristics and time to deceased donor kidney transplantation. The Kaplan-Meier estimate of median waiting time to transplantation was 284 days (95% confidence interval, 263 to 300 days) and varied from 14 to 1313 days across donor service areas. Overall, 29% of pediatric-quality kidneys were locally diverted to adults. Compared with areas with short waiting times, areas with long waiting times had a lower ratio of pediatric-quality kidneys to candidates (3.1 versus 5.9; Preference areas with ≥5:1 kidneys/candidates; Ppediatric deceased donor kidney transplantation exists and is highly associated with local supply and demand factors. Future organ allocation policy should address this geographic inequity.

  14. Liver transplantation in children using organs from young paediatric donors.

    Herden, Uta; Ganschow, Rainer; Briem-Richter, Andrea; Helmke, Knut; Nashan, Bjoern; Fischer, Lutz


    Nowadays, most paediatric liver transplant recipients receive a split or other technical variant graft from adult deceased or live donors, because of a lack of available age- and size matched paediatric donors. Few data are available, especially for liver grafts obtained from very young children (transplantations between 1989 and 2009. Recipients were divided into five groups (1-5) depending on donor age (transplantations from deceased donors were performed; 1- and 5-year graft survival rates were 75%, 80%, 78%, 81%, 74% and 75%, 64%, 70%, 67%, 46%, and 1- and 5-year patient survival rates were 88%, 91%, 90%, 89%, 78% and 88%, 84%, 84%, 83%, 63% for groups 1-5, respectively, without significant difference. Eight children received organs from donors younger than 1 year and 45 children received organs from donors between 1 and 6 years of age. Overall, vascular complications occurred in 13.2% of patients receiving organs from donors younger than 6 years. Analysis of our data revealed that the usage of liver grafts from donors younger than 6 years is a safe procedure. The outcome was comparable with grafts from older donors with excellent graft and patient survival, even for donors younger than 1 year.

  15. EBV-positive B cell cerebral lymphoma 12 years after sex-mismatched kidney transplantation: post-transplant lymphoproliferative disorder or donor-derived lymphoma?

    Phelan, Paul J


    We present a follow-up case report of possible transmission of lymphoma 12 years after deceased-donor renal transplantation from a male donor who was found at autopsy to have had an occult lymphoma. The female recipient underwent prompt transplant nephrectomy. However, 12 years later, she presented with cerebral B cell lymphoma. A donor origin for the cerebral lymphoma was supported by in situ hybridization demonstration of a Y chromosome in the lymphoma. There was a dramatic resolution of the cerebral lesions with tapering of immunosuppression and introduction of rituximab treatment. The finding of a Y chromosome in the cerebral lymphoma does not exclude a host contribution to lymphoma development.

  16. Does daily urine output really matter in renal transplantation?

    Tillou, Xavier; Lee-Bion, Adrien; Hurault de Ligny, Bruno; Orczyk, Clément; Le Gal, Sophie; Desmonts, Alexis; Bensadoun, Henri; Doerfler, Arnaud


    Our objective was to clarify the clinical outcome of renal transplantation based on residual daily urine output (RDUO). We retrospectively analyzed a prospective database of 276 patients who underwent renal transplantation (Tx) between January 2008 and December 2012. Patients had pre-transplantation daily urine output measurement of 24-h proteinuria and were clinically re-evaluated the day before transplantation. We included patients with no daily urine output and those with residual daily urine output. Real bladder capacity was not measured. We excluded patients with a history of lower urinary tract malformation, those treated by trans-ileal conduit or enterocystoplasty, and those with early graft thrombosis or graft primary non-function. Sex ratio, age at Tx, pre-Tx MHC antibodies levels, donor age, and cold ischemia duration were not significantly different between the 2 groups. Dialysis duration was longer in group I (p<0.001). The dialysis duration was correlated with the volume of residual urine output (r=0.12, p<0.0001). We found 14 (19.4%) urological complications in Group I (11 urinary leaks and 3 urethral stenosis) and 13 (6.4%) in Group II (5 urinary leaks and 8 stenosis). This difference was significant (p=0.0013 and relative risk [RR]=2.2). Absence of residual daily urine output was a risk factor of post-transplantation urinary leak (p<0.0001: RR=2.95). At 3 years, graft survival was 74.7% and 94.6%, respectively, in Group I and II (p=0.003). The absence of residual daily urine output seems to be a major risk factor for urological complications. Taking into account recipient residual daily urine output should modify surgical strategy during renal transplantation.

  18. Leukemia in donor cells after allogeneic hematopoietic stem cell transplant


    The development of leukemia in donor cells after allogeneic hematopoietic stem cell transplant is an extremely rare event. We report here the case of a patient who developed myelodysplastic syndrome/acute myeloid leukemia, in cells of donor origin 3.5 years after related donor HSCT for refractory chronic lymphocytic leukemia and therapy-induced myelodysplastic syndrome. The origin of the leukemia was determined by analysis of minisatillite polymorphism tested on CD34(+) cells.

  19. Determinants of graft survival in pediatric and adolescent live donor kidney transplant recipients: a single center experience.

    El-Husseini, Amr A; Foda, Mohamed A; Shokeir, Ahmed A; Shehab El-Din, Ahmed B; Sobh, Mohamed A; Ghoneim, Mohamed A


    To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

  20. Pediatric renal transplantation in a highly sensitised child-8 years on.

    Quinlan, Catherine


    Highly sensitised children have markedly reduced chances of receiving a successful deceased donor renal transplant, increased risk of rejection, and decreased graft survival. There is limited experience with the long-term followup of children who have undergone desensitization. Following 2 failed transplants, our patient was highly sensitised. She had some immunological response to intravenous immunoglobulin (IVIg) but this was not sustained. We developed a protocol involving sequential therapies with rituximab, IVIg, and plasma exchange. Immunosuppressant therapy at transplantation consisted of basiliximab, tacrolimus, mycophenolate mofetil, and steroids. At the time of transplantation, historical crossmatch was ignored. Current CDC crossmatch was negative, but T and B cell flow crossmatch was positive, due to donor-specific HLA Class I antibodies. Further plasma exchange and immunoglobulin therapy were given pre- and postoperatively. Our patient received a deceased donor-kidney-bearing HLA antigens to which she originally had antibodies, which would have precluded transplant. The graft kidney continues to function well 8 years posttransplant.

  1. Perspectives on communication issues among transplant and procurement professionals, transplant recipients, and donor families.

    Politoski, G; Coolican, M; Casey, K


    Communication among professionals, donor families, and transplant recipients is a controversial topic. Traditionally, transplant and procurement professionals have made the decision about the type and frequency of information that a donor family and transplant recipient receive regarding one another, and relationships that might develop as a result. Information obtained through questionnaires demonstrated inconsistency in addressing donor family and transplant recipient needs for initial and follow-up information and communication-not only between clinical transplant and procurement donation coordinators, but within organizations involved in the care and support of these people. This wide variance regarding communication among all disciplines demonstrated a need for standardization of practice guidelines. Guidelines are being developed through collaboration of the major organizations involved in the care of donor families and transplant recipients to standardize communication practices throughout the United States.

  2. [Preventive renal transplantation: considerations and future plans].

    Segoloni, G P


    A kidney transplant before the start of dialysis or after only a short period of dialysis is acknowledged as the best therapeutic option for the uremic patient. However, the number of patients in Italy waiting for a kidney is stable (around 6,400 at the latest report) and the annual number of transplants is not increasing (a slight decrease is forecast for 2007). Opening the deceased-donor waiting list to patients who are not yet on dialysis remains a matter of debate and has been possible only in Tuscany thanks to the high rate of kidney procurement in this region. As far as the Piedmont region is concerned, the balance between performed transplants and new candidates for transplantation is stable, with a mean waiting time of nearly 2 years. Taking into account also the current decline in donations, the possibility of placing pre-dialytic patients on the waiting list requires further evaluation. Nevertheless, some strategies may be within reach. Above all, the use of kidneys from living donors, which represents the ideal condition for preventive transplantation, should be extended. For patients lacking a suitable living donor, a program of earlier admission to waiting lists should be activated.

  3. Chronic Acquired Demyelinating Polyneuropathy following Renal Transplantation

    Younger, D. S.; Stuart Orsher


    The clinical, laboratory, and treatment findings of a patient with chronic acquired demyelinating polyneuropathy (CADP) in association with renal transplantation are described. Like the present case, many such patients have been described under the rubric of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP).

    Snijder, P. M.; van den Berg, E.; Whiteman, M.; Bakker, S. J. L.; Leuvenink, H. G. D.; van Goor, H.


    Once patients with kidney disease progress to end-stage renal failure, transplantation is the preferred option of treatment resulting in improved quality of life and reduced mortality compared to dialysis. Although 1-year survival has improved considerably, graft and patient survival in the long ter

  5. Kidney transplantation from donors with hepatitis C infection.

    Veroux, Massimiliano; Corona, Daniela; Sinagra, Nunziata; Giaquinta, Alessia; Zerbo, Domenico; Ekser, Burcin; Giuffrida, Giuseppe; Caglià, Pietro; Gula, Riccardo; Ardita, Vincenzo; Veroux, Pierfrancesco


    The increasing demand for organ donors to supply the increasing number of patients on kidney waiting lists has led to most transplant centers developing protocols that allow safe utilization from donors with special clinical situations which previously were regarded as contraindications. Deceased donors with previous hepatitis C infection may represent a safe resource to expand the donor pool. When allocated to serology-matched recipients, kidney transplantation from donors with hepatitis C may result in an excellent short-term outcome and a significant reduction of time on the waiting list. Special care must be dedicated to the pre-transplant evaluation of potential candidates, particularly with regard to liver functionality and evidence of liver histological damage, such as cirrhosis, that could be a contraindication to transplantation. Pre-transplant antiviral therapy could be useful to reduce the viral load and to improve the long-term results, which may be affected by the progression of liver disease in the recipients. An accurate selection of both donor and recipient is mandatory to achieve a satisfactory long-term outcome.

  6. Second Unrelated Donor Hematopoietic Cell Transplantation for Primary Graft Failure

    Schriber, Jeffrey; Agovi, Manza-A.; Ho, Vincent; Ballen, Karen K.; Bacigalupo, Andrea; Lazarus, Hillard M.; Bredeson, Christopher N.; Gupta, Vikas; Maziarz, Richard T.; Hale, Gregory A.; Litzow, Mark R.; Logan, Brent; Bornhauser, Martin; Giller, Roger H.; Isola, Luis; Marks, David I.; Rizzo, J. Douglas; Pasquini, Marcelo C.


    Failure to engraft donor cells is a devastating complication after allogeneic hematopoietic cell transplantation (HCT). We describe the results of 122 patients reported to the National Marrow Donor Program between 1990 and 2005, who received a second unrelated donor HCT after failing to achieve an absolute neutrophil count of ≥ 500/ μL without recurrent disease. Patients were transplanted for leukemia (n=83), myelodysplastic disorders (n=16), severe aplastic anemia (n=20) and other diseases (n=3). The median age was 29 years. Twenty-four patients received second grafts from a different unrelated donor. Among 98 patients who received a second graft from the same donor, 28 received products that were previously collected and cryopreserved for the first transplantation. One-year overall survival after second transplant was 11% with 10 patients alive at last follow up. We observed no differences between patients who received grafts from the same or different donors, or in those who received fresh or cryopreserved product. The outcomes after a second allogeneic HCT for primary graft failure are dismal. Identifying risk factors for primary graft failure can decrease the incidence of this complication. Further studies are needed to test whether early recognition and hastened procurement of alternative grafts can improve transplant outcomes for primary graft failure. PMID:20172038

  7. Denovo Post Renal Transplantation Inflammatory Bowel Disease

    Halim M


    Full Text Available Post-renal transplant de-novo inflammatory bowel disease (IBD may develop despite the presence of mycophenolate mofetil (MMF, a drug used for treatment of IBD, in the immunosuppressive regimen. A 39-year-old man received live unrelated renal transplant, and was started postoperatively on prednisolone, MMF, and tacrolimus, which was changed to sirolimus when he developed diabetes mellitus two months post-transplant. Nine months post-transplant, the patient developed recurrent attacks of bloody diarrhea and ischio-rectal abscesses complicated by anal fistulae not responding to routine surgical treatment. Colonoscopy diagnosed IBD, a Crohn′s disease-like pattern. The patient was treated with steroids and 5-aminosalicylic acid (5-ASA in addition to a two months course of ciprofloxacin and metronidazole. He became asymptomatic and rectal lesions healed within one month of treatment. The patient continued to be asymptomatic, and he maintained normal graft function on the same immunosuppressive treatment in addition to 5-ASA. We conclude that de-novo IBD disease can develop in renal transplant recipients in spite of immunosuppressive therapy including MMF.

    Background. Renal transplantation is the treatment of choice for end stage renal disease. Although there is more depression in wait-listed versus transplant patients, depression persists after transplantation. We investigated the determinants of depression in renal transplantation recipients (RTRs)

  9. Characterization of post transplantation lymphoma in feline renal transplant recipients.

    Durham, A C; Mariano, A D; Holmes, E S; Aronson, L


    The development of malignant neoplasia following solid organ transplantation and immunosuppression is well recognized in man. Post-transplantation malignant tumours include non-melanoma skin cancers, non-Hodgkin's lymphoma and Kaposi's sarcoma and many of these cancers have a known or suspected viral cause. A similar increased incidence of cancer is seen in cats that have received a renal transplant and lymphoma is the predominant neoplasm in this population. This study examines a population of cats that received renal transplants at the University of Pennsylvania School of Veterinary Medicine and subsequently developed neoplasia. From 1998 to 2010, 111 cats were transplanted and 25 cats developed cancer (22.5%). Fourteen of the 25 cats were diagnosed with lymphoma (56%), making it the most common tumour in this patient population. The median interval between transplantation and diagnosis of lymphoma was 617 days and the median survival time (MST) following the diagnosis of lymphoma was 2 days. Tissues from seven of these cats were available for histopathological review as either samples collected at necropsy examination (n = 5) or biopsy submissions (n = 2). Five of these cats had multiorgan involvement with sites including the liver, spleen, peripheral and mesenteric lymph nodes, small intestine, urinary bladder, heart, mesenteric fat and body wall. Four of the cats with multiorgan disease had involvement of the renal allograft two of which also had lymphoma of the native kidney. All lymphomas were classified as mid to high grade, diffuse large B-cell lymphoma, which is also the most common lymphoma subtype in human cases of post-transplantation lymphoproliferative disorders.

  10. Patients with a Failed Renal Transplant

    Tülin AKAGÜN


    Full Text Available Renal transplantation is the best method of renal replacement therapy for patients with end-stage renal disease. On the other hand in the early or late period of transplantation, majority of patients suffer from allograft failure and return to the dialysis. These patients carry the risks of adverse effects of previous immunosuppressive therapy (i.e infections and cancers. Furthermore, worse quality of life and many limitations of dialysis result in psychological problems. The controversial issues in treatment of these patients can be summarized under the headings of : 1- In which stage of allograft failure these patients should return to dialysis? 2- Which is the most appropriate renal replacement therapy after the renal allograft failure? 3- What are the main problems during dialysis practice and how should these problems be managed? 4- How should the immunosupression regimen be managed? 5- What are the indications for transplant nephrectomy? 6- What are the advantages and drawbacks of retransplantation? In this review these problems were discussed. [ Türkçe Özet ] [ PDF ] [ Benzer Makaleler

  11. Donor-Derived Myeloid Sarcoma in Two Kidney Transplant Recipients from a Single Donor

    Amudha Palanisamy


    Full Text Available We report the rare occurrence of donor-derived myeloid sarcoma in two kidney transplant patients who received organs from a single deceased donor. There was no evidence of preexisting hematologic malignancy in the donor at the time of organ recovery. Both recipients developed leukemic involvement that appeared to be limited to the transplanted organ. Fluorescence in situ hybridization (FISH and molecular genotyping analyses confirmed that the malignant cells were of donor origin in each patient. Allograft nephrectomy and immediate withdrawal of immunosuppression were performed in both cases; systemic chemotherapy was subsequently administered to one patient. Both recipients were in remission at least one year following the diagnosis of donor-derived myeloid sarcoma. These cases suggest that restoration of the immune system after withdrawal of immunosuppressive therapy and allograft nephrectomy may be sufficient to control HLA-mismatched donor-derived myeloid sarcoma without systemic involvement.

  12. Pulmonary artery patch for an inadequate donor atrial cuff in the absence of donor pericardium in lung transplantation.

    Sugimoto, Seiichiro; Yamane, Masaomi; Miyoshi, Kentaroh; Kurosaki, Takeshi; Otani, Shinji; Miyoshi, Shinichiro; Oto, Takahiro


    In cadaveric lung transplantation (LTx), a donor lung with an inadequate donor left atrial cuff is considered a "surgically marginal donor lung". The donor pericardium is commonly applied to reconstruct the inadequate donor left atrial cuff; however, in some cases, the donor pericardium is inadvertently removed during the lung procurement. We devised an alternative technique for reconstruction to overcome the absence of pericardium in a donor lung with an inadequate atrial cuff, using a patch of the donor pulmonary artery (PA) in single lung transplantation. In a recent case of lung transplantation in which the donor pericardium had been removed, we harvested a segment of the right PA distal to the main PA of the donor and used a PA patch to repair the inadequate donor left atrial cuff. No vascular complications were encountered in the recipient, who remains in good health after the transplantation.

  13. [Lung transplantation with uncontrolled non-heart-beating donors. Transplantation. Donor prognostic factor and immediate evolution post transplant].

    Rodríguez, Diego A; Del Río, Francisco; Fuentes, Manuel E; Naranjo, Sara; Moradiellos, Javier; Gómez, David; Rubio, Juan José; Calvo, Elpidio; Varela, Andrés


    Uncontrolled donation after cardiac death (DACD) has become an alternative to lung transplantation with encephalic-death donation. The main objective of this study is to describe the incidence of clinically relevant events in the period of thirty days after lung transplant with uncontrolled DACD and the influence of factors depending on the donor and donation process as well. Historical cohort study of 33 lung transplant receivers at Hospital Puerta de Hierro and Hospital Marqués de Valdecilla with 32 DACD from Hospital Clínico San Carlos from 2002 to 2008. We studied surgical and medical complications, primary graft dysfunction, acute rejection, pneumonia and mortality. We made an evaluation of the donor characteristics and donation procedure times (minutes). Median age of recipients was 50.5 years (interquartile range, 38.5-58). There were 28 males and 5 females. Cumulative incidence of events in the first month was: pneumonia 10 (31.3%); primary graft dysfunction 15 (46.9%); rejection 12 (37.5%); mortality 4 (12.1%); medical complications 25 (78.1%); and surgical complications 18 (56.3%). Median time of cardiac arrest was higher in those who presented pneumonia (15 vs. 7.5; p = 0.027). Median time of cold ischemia was higher in those who presented surgical complications and mortality (436 vs. 343.5; p = 0.04; 505 vs. 410; p = 0.033, respectively), and median of total ischemia times were longer in the recipients who died (828 vs. 695; p = 0.036). Uncontrolled DACD are a valid alternative for expanding the donor pool in order to mitigate the current shortage of lungs that are valid for transplantation. The incidence of complications is comparable with published data in the literature. Copyright © 2010 SEPAR. Published by Elsevier Espana. All rights reserved.

  14. Acute pancreatitis, acute hepatitis and acute renal failure favourably resolved in two renal transplant recipients.

    Voiculescu, Mihai; Ionescu, Camelia; Ismail, Gener; Mandache, Eugen; Hortopan, Monica; Constantinescu, Ileana; Iliescu, Olguta


    Renal transplantation is often associated with severe complications. Except for acute rejection, infections and toxicity of immunosuppressive treatment are the most frequent problems observed after transplantation. Infections with hepatic viruses (HBV, HDV, HCV, HGV) and cytomegalic virus (CMV) are the main infectious complications after renal transplantation. Cyclosporine toxicity is not unusual for a patient with renal transplantation and is even more frequent for patients with hepatic impairment due to viral infections. The subjects of this report are two renal transplant recipients with acute pancreatitis, severe hepatitis and acute renal failure on graft, receiving immunosuppressive therapy for maintaining renal graft function

  17. Medical and psychologic outcome of living lobar lung transplant donors.

    Prager, Laura M; Wain, John C; Roberts, David H; Ginns, Leo C


    Living donor lobar lung transplantation is a viable therapy for carefully selected patients with end-stage pulmonary disease. Its success is largely dependent upon donor outcome, including both physical and emotional factors. To date, there has been little focus on psychosocial outcomes of lobar lung donors. Retrospective evaluation of 15 of 20 living lobar lung transplant donors was performed. Donors underwent evaluation of pulmonary function after recovery from donor lobectomy. Participants completed two self-report questionnaires, the SF-36 Health Survey (SF-36) and the Beck Depression Inventory (BDI), as well as an open-ended psychiatric interview. After lobar donation, mean forced expiratory volume in 1 second (FEV(1)) decreased by 21 +/- 2%, forced vital capacity (FVC) decreased by 16 +/- 3%, total lung capacity (TLC) decreased by 15 +/- 3%, and single-breath diffusing capacity (DLCO) decreased by 14 +/- 4%. All subjects scored higher than the national average on both the physical and mental health components of the SF-36. The BDI scores showed no evidence of clinical depression. However, the subjective interviews elicited two common complaints: (1) a decline in exercise performance, not accounted for by resting lung function measurements; and (2) a dissatisfaction with the degree of acknowledgment of their donation. Living lobar lung transplant donors enjoy generally satisfactory physical and emotional health. Donors report positive feelings about donation, but wish to be recognized and valued by the transplant team and by the recipient. Despite preservation of lung function within the normal range, some donors also experience a subjective decline in exercise tolerance. Long-term medical and psychologic follow-up appears warranted to monitor symptoms of exercise impairment and to enhance the donor experience.

  18. Renal transplantation in the Roma ethnicity-do all patients have equal chance for transplantation?

    Basic-Jukic, N; Novosel, D; Juric, I; Kes, P


    Racial and ethnic disparities exist in access to kidney transplantation worldwide. The Roma people are often socially deprived, uneducated, and unemployed. We investigated all dialysis centers in Croatia to determine number of Roma people on dialysis as well as their access and reasons for eventual failure to enter the waiting list. There are 9463 registered Roma people in Croatia, however, the estimated number reaches 40,000. Twenty-five Roma patients required renal replacement therapy, giving a prevalence of 830 per million people (pmp), compared with 959 pmp among the general population. Average age at the start of dialysis was 29 vs 67 years; waiting time to kidney transplantation was 48.9 vs 53.5 months; mean age at the time of transplantation was 33.18 vs 48.01 years in Roma versus the general population respectively. One patient received a kidney allograft from a living unrelated spousal donor, and all others from deceased individuals. Patients were followed for 51.5 months (range, 6-240). The most frequent post-transplant complications were urinary tract infections. One patient lost a graft due to severe acute rejection caused by noncompliance. Two young patients were also noncompliant with immunosuppressive medications. One patient died with a functioning graft at 20 years after transplantation due to cardiovascular disease. Among 14 Roma patients currently been treated with hemodialysis in Croatia, 10 are old with clinical contraindications for transplantation; 1 is on the waiting list; 1 left hospitalization for pretransplant evaluation twice; 1 refused evaluation; and 1 is currently being evaluated for the waiting list. The Roma people have excellent access to renal transplantation in Croatia. Many of them refuse evaluation. More efforts should be invested in their education to improve compliance and their post-transplant outcomes.

  19. Basiliximab induced non-cardiogenic pulmonary edema in two pediatric renal transplant recipients.

    Dolan, Niamh


    We report two cases of non-cardiogenic pulmonary edema as a complication of basiliximab induction therapy in young pediatric renal transplant patients identified following a retrospective review of all pediatric renal transplant cases performed in the National Paediatric Transplant Centre, Childrens University Hospital, Temple Street, Dublin, Ireland. Twenty-eight renal transplantations, of which five were living-related (LRD) and 23 were from deceased donors (DD), were performed in 28 children between 2003 and 2006. In six cases, transplantations were pre-emptive. Immunosuppression was induced pre-operatively using a combination of basiliximab, tacrolimus and methylprednisolone in all patients. Basiliximab induction was initiated 2 h prior to surgery in all cases and, in 26 patients, basiliximab was re-administered on post-operative day 4. Two patients, one LRD and one DD, aged 6 and 11 years, respectively, developed acute non-cardiogenic pulmonary edema within 36 h of surgery. Renal dysplasia was identified as the primary etiological factor for renal failure in both cases. Both children required assisted ventilation for between 4 and 6 days. While both grafts had primary function, the DD transplant patient subsequently developed acute tubular necrosis and was eventually lost within 3 weeks due to thrombotic microangiopathy and severe acute antibody-mediated rejection despite adequate immunosuppression. Non-cardiogenic pulmonary edema is a potentially devastating post-operative complication of basiliximab induction therapy in young pediatric patients following renal transplantation. Early recognition and appropriate supportive therapy is vital for patient and, where possible, graft survival.

  20. Alternative donor transplants for severe aplastic anemia: current experience.

    Bacigalupo, Andrea; Sica, Simona


    Patients with acquired severe aplastic anemia (SAA), who lack a human leukocyte antigen (HLA) identical sibling donor (SIB), have two therapeutic options: immunosuppressive therapy with anti-thymocyte globulin (ATG) and cyclosporine (CsA), or a transplant from an alternative donor. In these patients, the current guidelines of the European Group for Blood and Marrow Transplantation (EBMT) call for a course of ATG + CsA first and transplantation in case of no response. The alternative donor source can be an unrelated donor (UD), a cord blood (CB) unit, or a family mismatched member, in most instances genetically HLA haplo-mismatched (HAPLO). In the present review, we will discuss recent results of transplants from matched UD and SIB donors, with significantly improved outcome, especially with UD in the past decade. We will also be looking at CB transplants, and the problems of limited stem cell dose. Finally HAPLO grafts have been explored in patients lacking or having rejected an unrelated or CB graft: early results seem encouraging, though the procedure should still be considered experimental.

  1. Ethical and legal issues in renal transplantation in Nigeria

    S O Ajayi


    Full Text Available With the increasing number of patients being offered kidney transplantation by many centers in the developing world, it is not unexpected that there would be attendant ethical and legal issues even when the selection process for transplantation seems medically justified. Because of the inadequate infrastructure for hemodialysis and peritoneal dialysis, coupled with the challenges of logistics for maintenance dialysis, transplantation would seem to be the best option for patients with end-stage renal failure, even in developed economies where these can easily be tackled. The main issues here revolve around incentives for donors, organ trade and trafficking and the economics of eliminating the waiting list and the criminal activities of organ trans-plantation. In the developing world, with the current level of corruption and poverty, there is a need to redouble efforts to monitor transplant activities. Professional bodies should take the lead in this regard. Furthermore, there is a need for governments to engage in public consultation and community awareness concerning organ donation in living and deceased persons.

  2. Renal Allograft Outcome After Simultaneous Heart and Kidney Transplantation.

    Grupper, Avishay; Grupper, Ayelet; Daly, Richard C; Pereira, Naveen L; Hathcock, Matthew A; Kremers, Walter K; Cosio, Fernando G; Edwards, Brooks S; Kushwaha, Sudhir S


    Chronic kidney disease frequently accompanies end-stage heart failure and may result in consideration of simultaneous heart and kidney transplantation (SHKT). In recent years, there has been a significant increase in SHKT. This single-center cohort consisted of 35 patients who underwent SHKT during 1996 to 2015. The aim of this study was to review factors that may predict better long-term outcome after SKHT. Thirteen patients (37%) had delayed graft function (DGF) after transplant (defined as the need for dialysis during the first 7 days after transplant), which was significantly associated with mechanical circulatory support device therapy and high right ventricular systolic pressure before transplant. Most of the recipients had glomerular filtration rate (GFR) ≥50 ml/min/1.73 m(2) at 1 and 3 years after transplant (21 of 26 [81%] and 20 of 21 [95%], respectively). Higher donor age was associated with reduced 1-year GFR (p = 0.017), and higher recipient pretransplant body mass index was associated with reduced 3-year GFR (p = 0.008). There was a significant association between DGF and reduced median GFR at 1 and 3 years after transplant (p <0.005). Patient survival rates at 6 months, 1, and 3 years after transplant were 97%, 91%, and 86% respectively. In conclusions, our data support good outcomes after SHKT. Mechanical circulatory support device therapy and pulmonary hypertension before transplant are associated with DGF, which is a risk factor for poor long-term renal allograft function.

  3. Recommendations for use of marginal donors in heart transplantation: Brazilian Association of Organs Transplantation guideline.

    Fiorelli, A I; Stolf, N A G; Pego-Fernandes, P M; Oliveira Junior, J L; Santos, R H B; Contreras, C A M; Filho, D D L; Dinkhuysen, J J; Moreira, M C V; Mejia, J A C; Castro, M C R


    The high prevalence of heart failure has increased the candidate list for heart transplantation; however, there is a shortage of viable donated organs, which is responsible for the high mortality of patients awaiting a transplantation. Because the marginal donor presents additional risk factors, it is not considered to be an ideal donor. The use of a marginal donor is only justified in situations when the risk of patient death due to heart disease is greater than that offered by the donor. These recommendations sought to expand the supply of donors, consequently increasing the transplant rate. We selected articles based on robust evidence to provide a substratum to develop recommendations for donors who exceed the traditional acceptance criteria. Recipient survival in the immediate postoperative period is intimately linked to allograft quality. Primary allograft failure is responsible for 38% to 40% of immediate deaths after heart transplantation: therefore; marginal donor selection must be more rigorous to not increase the surgical risk. The main donor risk factors with the respective evidence levels are: cancer in the donor (B), female donor (B), donor death due to hemorrhagic stroke (B), donor age above 50 years (relative risk [RR] = 1.5) (B), weight mismatch between donor and recipient 240 minutes (RR = 1.2) (B), left ventricular dysfunction with ejection fraction below 45% (B), and use of high doses of vasoactive drugs (dopamine > 15 mg/kg·min) (B). Factors that impact recipient mortality are: age over 50 years (RR = 1.5); allograft harvest at a distance; adult recipient weighing more than 20% of the donor; high doses of vasoactive drugs (dopamine greater than 15 mg/kg·min) and ischemic time >4 hours. The use of a marginal donor is only justified when it is able to increase life expectancy compared with clinical treatment, albeit the outcomes are interior to those using an ideal donor.

  4. Ethical considerations on kidney transplantation from living donors.

    Bruzzone, P; Pretagostini, R; Poli, L; Rossi, M; Berloco, P B


    Kidney transplantation from living donors is widely performed all over the world. Living nephrectomy for transplantation has no direct advantage for the donor other than increased self-esteem, but at least remains an extremely safe procedure, with a worldwide overall mortality rate of 0.03%. This theoretical risk to the donor seems to be justified by the socioeconomic advantages and increased quality of life of the recipient, especially in selected cases, such as pediatric patients, when living donor kidney transplantation can be performed in a preuremic phase, avoiding the psychological and physical stress of dialysis, which in children is not well tolerated and cannot prevent retarded growth. According to the Ethical Council of the Transplantation Society, commercialism must be prevented, not only for ethical but also medical reasons. The risks are too high not only for the donors, but also for the recipients, as a consequence of poor donor screening and evaluation with consequent transmission of human immunodeficiency virus or other infectious agents, as well as inappropriate medical and surgical management of donors and also of recipients, who are often discharged too early. Most public or private insurance companies are considering kidney donation a safe procedure without long-term impairment and, therefore, do not increase the premium, whereas recipient insurance of course should cover hospital fees for the donors. "Rewarded gifting" or other financial incentives to compensate for the inconvenience and loss of income related to the donation are not advisable, at least in our opinion. Our center does not perform anonymous living organ donation or "cross-over" transplantation.

  5. Do the outcomes of living donor renal allograft recipients differ with peritoneal dialysis and hemodialysis as a bridge renal replacement therapy?

    Prasad, Narayan; Vardhan, Harsh; Baburaj, Vinod P; Bhadauria, Dharmendra; Gupta, Amit; Sharma, Raj K; Kaul, Anupama


    This study was undertaken to compare the outcomes of living donor renal transplant recipients using peritoneal dialysis (PD) and hemodialysis (HD) as a bridge modality for renal replacement therapy till renal transplantation. The demographic profiles of the recipients and donors, the patients' native kidney disease (diabetic versus non-diabetic), duration on dialysis, requirement of anti-hypertensive drugs, number of blood transfusions, human leukocyte antigen (HLA) mismatch status, pre- and post-transplant infectious complications, and post-transplant outcomes of patients were compared between the two groups. The demographic features of the study patients were similar in the two groups. The duration of dialysis prior to transplant was significantly longer in the PD group than in the HD group of patients. The anti-hypertensive drug requirement was lower and the hemoglobin level and residual urine volume at the time of transplant were relatively better in the PD patients compared to the HD patients. The number of acute rejection episodes, delayed graft function, surgical complications, glomerular filtration rate at one month and at the last follow-up, were also similar in both groups. The short-term and long-term graft survival was similar in both groups of patients. The one-, two-, five-, and eight-year death-censored graft survival rates of the PD patients were 98, 95, 85, and 73%, respectively, and in the HD group of patients, they were 100, 93, 84, and 79%, respectively. The one-, two-, five-, and eight-year patient survival rates in the PD group were 97, 92, 77, and 66%, respectively, and in the HD group, they were 97, 92, 79, and 69%, respectively. Our study suggests that the outcomes of the living donor renal allograft recipients did not differ between the groups of patients who used PD or HD as renal replacement therapy prior to renal transplantation.

  7. Renal cancer in kidney transplanted patients.

    Frascà, Giovanni M; Sandrini, Silvio; Cosmai, Laura; Porta, Camillo; Asch, William; Santoni, Matteo; Salviani, Chiara; D'Errico, Antonia; Malvi, Deborah; Balestra, Emilio; Gallieni, Maurizio


    Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

  8. Lymphocele – urological complication after renal transplantation

    Wojciech Krajewski


    Full Text Available Renal transplantation is the best renal replacement treatment. It provides longer survival and a better quality of life. The outcome of renal transplantation is influenced by the occurrence of various complications, including urological. One of the most frequently occurring complicationsis lymphocele. Most cases of lymphocele develop during a period of several weeks after the procedure of transplantation. However, there are some literature reports concerning lymphocele diagnosis in the later period, even after several years. Most cases of lymphocele are asymptomatic and are diagnosed accidentally. Nevertheless, a large lymphocele may press the kidney, ureter, urinary bladder or neighbouring blood vessels, causing deterioration of renal function, leg oedema and thrombosis of iliac vessels. Among other complications there are infections. The cause of lymphocele is collection of the lymph drained from damaged lymph vessels surrounding iliac blood vessels and/or lymph vessels of the graft. Important factors predisposing to lymphocele are immunosuppressive treatment, including mTOR inhibitors, mycophenolic acid derivatives and high doses of glucosteroids. Factors favouring occurrence of lymphocele comprise obesity, diabetes, elderly age of recipient, long time of warm ischaemia, acute rejection episodes and delayed graft function. The authors describe presently available treatment methods including aspiration and percutaneous drainage, with or without sclerotisation, drainage using the Tenckhoff catheter and laparoscopic or open fenestration. At present, laparoscopic fenestration is considered to be the most efficient and the safest method. However, there are clinical cases where open surgical treatment is necessary.

However, conflicting predisposing risk factors for TRAS have been reported in the literature.Objective: The aim of the present study was to assess the potential correlation between possible risk factors and TRAS in a group of living donor renal transplant recipients 1 year after the renal transplantation.Methods: We evaluated the presence of renal artery stenosis in 16 recipients who presented with refractory hypertension and/or allograft dysfunction 1 year after renal transplantation. Screening for TRAS was made by magnetic resonance angiography and diagnosis was confirmed by conventional renal angiography. Age, gender, history of acute rejection, plasma lipid profile, serum creatinine, blood urea nitrogen, serum uric acid, calcium phosphate (CaPO4 product, alkaline phosphatase, fasting blood sugar, hemoglobin, and albumin were compared between the TRAS and non-TRAS groups.Results: Of 16 kidney transplant recipients, TRAS was diagnosed in three patients (two men and one woman. High levels of calcium, phosphorous, CaPO4 product, and low-density lipoprotein (LDL cholesterol were significantly correlated with the risk of TRAS 1 year after renal transplantation (P < 0.05. Serum level of uric acid tended to have a significant correlation (P = 0.051.Conclusion: Correlation between high CaPO4 product, LDL cholesterol, and perhaps uric acid and TRAS in living

    AIM: To retrospectively evaluate the management and outcome of venous obstruction after living donor liver transplantation (LDLT).METHODS: From February 1999 to May 2009, 1 intraoperative hepatic vein (HV) tension induced HV obstruction and 5 postoperative HV anastomotic stenosis occurred in 6 adult male LDLT recipients. Postoperative portal vein (PV) anastomotic stenosis occurred in 1 pediatric left lobe LDLT. Patients ranged in age from 9 to 56 years (median, 44 years). An air balloon was used to correct the intraoperative HV tension. Emergent surgical reoperation, transjugular HV balloon dilatation with stent placement and transfemoral venous HV balloon dilatation was performed for HV stenosis on days 3, 15, 50, 55, and 270 after LDLT, respectively. Balloon dilatation followed with stent placement via superior mesenteric vein was performed for the pediatric PV stenosis 168 d after LDLT.RESULTS: The intraoperative HV tension was corrected with an air balloon. The recipient who underwent emergent reoperation for hepatic stenosis died of hemorrhagic shock and renal failure 2 d later. HV balloon dilatation via the transjugular and transfemoral venous approach was technically successful in all patients. The patient with early-onset HV stenosis receiving transjugular balloon dilatation and stent placement on the 15th postoperative day left hospital 1 wk later and disappeared, while the patient receiving the same interventional procedures on the 50th postoperative day died of graft failure and renal failure 2 wk later. Two patients with late-onset HV stenosis receiving balloon dilatation have survived for 8 and 4 mo without recurrent stenosis and ascites, respectively. Balloon dilatation and stent placement via the superior mesenteric venous approach was technically successful in the pediatric left lobe LDLT, and this patient has survived for 9 mo without recurrent PV stenosis and ascites.CONCLUSION: Intraoperative balloon placement, emergent reoperation, proper

  12. Alternative donor allogeneic hematopoietic cell transplantation for hemoglobinopathies.

    Alfraih, Feras; Aljurf, Mahmoud; Fitzhugh, Courtney D; Kassim, Adetola A


    Allogeneic hematopoietic stem cell transplantation (HSCT) offers a curative therapy for patients with hemoglobinopathies, mainly severe sickle cell disease (SCD) and thalassemia (TM). However, the applicability of HSCT has been limited mainly by donor availability, with a less than 25%-30% of eligible patients having human leukocyte antigen (HLA)-matched sibling donors. Previous outcomes using alternate donor options have been markedly inferior due to increased regimen-related toxicity, transplant-related mortality, graft failure, and graft-versus-host disease (GVHD). Advances in transplant technology, including high-resolution HLA typing, improved GVHD prophylactic approaches with tolerance induction, and better supportive care over the last decade, are addressing these historical challenges, resulting in increasing donor options. Herein, we review alternate donor HSCT approaches for severe SCD and TM using unrelated donors, umbilical cord blood units, or related haploidentical donors. Though this is an emerging field, early results are promising and in selected patients, this may be the preferred option to mitigate against the age-related morbidity and early mortality associated with these disorders.

    Ahmad, Tanveer; Kishore, Kolkebaile Sadanand; Maheshwarappa, Nandakumar Neralakere; Pasarad, Ashwini Kumar


    Renal transplantation remains a mainstay of therapy for the end-stage renal disease. Cardiac disease has a high prevalence in this patient population. Cardiovascular disease remains the leading cause of death among kidney transplantation patients. The cardiac disease accounts for 43% of all-cause mortality among dialysis patients and for ≈38% of all-cause mortality after transplantation. In this article, we review the factors and outcomes associated with valve surgeries in renal transplant recipients and evaluate the strategy for open heart surgery after renal transplantation performed.

  14. Renal transplantation--the Starzl influence.

    Salvatierra, O


    In summary, I have attempted to review with you some of Dr Starzl's numerous clinical and scientific contributions that have cut across the spectrum of the field of renal transplantation. It is thus not surprising that Dr Starzl was elected the first President of the American Society of Transplant Surgeons, singular recognition from his own peers for the many contributions and leadership that he has provided during the formative and developmental years of organ transplantation. In addition, Dr Starzl has been recognized with a number of other prestigious awards, among which was the David M. Hume Memorial Award, the highest honor bestowed by the National Kidney Foundation. Careful analysis of Dr Starzl's work therefore clearly indicates that many of his contributions since 1960 have been uniquely innovative, have provided many firsts, and have reflected the science and technology of transplantation as it is today, in 1987. Thus, it can be truly said that Dr Starzl, the surgeon-scientist, was not only a pioneer but also a leader and subsequently a giant in the field of clinical renal transplantation. He has left a lasting and indelible impact on the field, the Starzl influence, for which all of us, both patient and physician, are extremely grateful. Thank you very much, Dr Starzl.

  15. Intestinal Parasitic Infections in Renal Transplant Recipients

    EB Kia


    Full Text Available Background: Organ transplant recipients can experience serious diseases from infections due to emerging and reemerging parasitic infections. This study was carried out to evaluate the prevalence of intestinal parasites among renal transplant re-cipients of Iran. "nMethods: This cross-sectional study was conducted from June 2003 to August 2004 on renal transplant recipients in Iran. A total of 706 fecal samples obtained from randomly selected population originated from all over Iran. Patient's information was recorded in a questionnaire before sampling. A sample of stool was taken from each person. Direct wet smear exami-nation, formalin-ether concentration, Ziehl-neelsen staining, and agar plate culture were done for each sample. "nResults: Totally 32 patients (4.5% were positive for parasitic infections. In searching for emerging parasitic infections, the most prevalent parasites were found to be Blastocystis hominis, Giardia lamblia and Entamoeba coli, respectively. The merely ova which were seen were related to Hymenolepis nana. With investigation of healthy control, no significant differ-ence was found between transplanted and normal population. "nConclusion: The population showed controlled rate of intestinal infections probably due to regular awareness concerning risks of opportunistic infections; albeit regular surveillance through routine examination of stool samples for parasites seems considerably advantages the transplant recipient patients.

  16. Overview of Pregnancy in Renal Transplant Patients

    Silvi Shah


    Full Text Available Kidney transplantation offers best hope to women with end-stage renal disease who wish to become pregnant. Pregnancy in a kidney transplant recipient continues to remain challenging due to side effects of immunosuppressive medication, risk of deterioration of allograft function, risk of adverse maternal complications of preeclampsia and hypertension, and risk of adverse fetal outcomes of premature birth, low birth weight, and small for gestational age infants. The factors associated with poor pregnancy outcomes include presence of hypertension, serum creatinine greater than 1.4 mg/dL, and proteinuria. The recommended maintenance immunosuppression in pregnant women is calcineurin inhibitors (tacrolimus/cyclosporine, azathioprine, and low dose prednisone; and it is considered safe. Sirolimus and mycophenolate mofetil should be stopped 6 weeks prior to conception. The optimal time to conception continues to remain an area of contention. It is important that counseling for childbearing should start as early as prior to getting a kidney transplant and should be done at every clinic visit after transplant. Breast-feeding is not contraindicated and should not be discouraged. This review will help the physicians in medical optimization and counseling of renal transplant recipients of childbearing age.

  17. Adequacy of the ELISA test for screening corneal transplant donors.

    Goode, S M; Hertzmark, E; Steinert, R F


    Using a simple mathematical model, we calculated the risk for a patient undergoing penetrating keratoplasty to receive a cornea from a human immunodeficiency virus-infected donor despite negative results on serologic testing of donor serum. This error in serologic testing occurred when false-negative results were obtained from the enzyme-linked immunosorbent assay used to screen donor corneas for human immunodeficiency virus exposure. The average risk of transplanting an infected cornea was low, 0.03%, but increased by a factor of ten when donor tissue from donors at high risk for AIDS was used. Current screening procedures are probably adequate to prevent transmission of human immunodeficiency virus, but increased vigilance for high-risk donor populations may be appropriate.

  18. Effect of lymph leakage on renal allograft outcome from living donors

    Abolfazl Bohlouli


    Full Text Available Lymph leakage is a cause of prolonged fluid discharge in renal transplant patients. Lymph leakage during early post-transplantation is responsible for extracting immune substances; therefore, it may play a role in prognosis of the transplanted kidney. In this study, we aimed to investigate the effects of lymph leakage on different factors that play significant roles in renal allograft outcome. During the present case-control study, we evaluated 62 renal allograft recipients in which 31 subjects were complicated with lymph leakage and enrolled as the study group. The other 31 subjects were included in the control group who did not experience any lymph leakage during their post-transplantation period. All kidneys were transplanted from living donors. We investigated and compared the renal allograft rejection rate, hospitalization duration, serum urea, creatinine (Cr and cyclosporine (CsA levels, antithymoglobin (ATG administration and treatment duration between the study and the control groups. There were no significant difference in the urea and Cr levels between the two groups (P >0.05. Early (one week and late (one month serum CsA levels of the study group were significantly higher than in the control group (P = 0.005 and P = 0.006. The number of days in which ATG receivers responded to therapy was significantly lower for the control group (P = 0.008. 21.93% of the study group subjects experienced allograft rejection, while this rejection probability was 28.38% for the control group (P = 0.799. Lymph leakage has no prominent role in renal function, which is estimated by Cr and urea levels in patients′ serum during the days after transplantation. CsA level was higher in patients with lymph leakage, and all cases of allograft rejection were in the subjects with lymph leakage.

  19. Prevalence of Anemia in Renal Transplant Patients in Turkey

    Alparslan MERDİN


    Full Text Available OBJECTIVE: Post-transplant anemia is a common complication in renal allograft recipients. The most common causes are impaired graft function, immunosuppressive drugs, and infections. The aim of our study was to further investigate the prevalence of anemia before and after renal transplantation in renal allograft recipients in Turkey. MATERIAL and METHODS: We assessed 464 patients who received a kidney transplant between the years 2010 and 2012. The prevalence of anemia was evaluated before transplantation and at the 3 rd and at 6th months after transplantation. Our study is a retrospective study. RESULTS: The prevalence of anemia at the 6th month after the transplant surgery was 28.8%. The percentage of the patients who did not have anemia prior to the transplant surgery, and who developed anemia after the transplantation was 24.4%. CONCLUSION: Our findings are similar to those found in the literature, and show that anemia is a very common entity after renal transplantation.

  20. Fibromuscular dysplasia in living renal donors: Still a challenge to computed tomographic angiography

    Blondin, D., E-mail: blondin@med.uni-duesseldorf.d [Institute of Radiology, University Hospital Duesseldorf, Moorenstr. 5, D-40225 Duesseldorf (Germany); Lanzman, R.; Schellhammer, F. [Institute of Radiology, University Hospital Duesseldorf, Moorenstr. 5, D-40225 Duesseldorf (Germany); Oels, M. [Department of Nephrology (Germany); Grotemeyer, D. [Department of Vascular Surgery and Renal Transplantation (Germany); Baldus, S.E. [Institute of Pathology (Germany); Rump, L.C. [Department of Nephrology (Germany); Sandmann, W. [Department of Vascular Surgery and Renal Transplantation (Germany); Voiculescu, A. [Department of Nephrology (Germany)


    Background: Computed tomographic angiography has become the standard evaluating method of potential living renal donors in most centers. Although incidence of fibromuscular dysplasia is low (3.5-6%), this pathology may be relevant for success of renal transplantation. The incidence of FMD in our population of LRD and reliability of CTA for detecting vascular pathology were the aims of this study. Materials and methods: 101 living renal donors, examined between 7/2004 and 9/2008 by CTA, were included in a retrospective evaluation. The examinations were carried out using a 64 Multi-detector CT (Siemens Medical Solutions, Erlangen). The presence or absence of the characteristic signs of fibromuscular dysplasia, as 'string-of-beads' appearance, focal stenosis or aneurysms, were assessed and graded from mild (=1) to severe (=3). Furthermore, vascular anatomy and arterial stenosis were investigated in this study. Retrospective analysis of CTA and ultrasound were compared with operative and histological reports. Results: Four cases of fibromuscular dysplasia (incidence 3.9%) in 101 renal donors were diagnosed by transplanting surgeons and histopathology, respectively. Three cases could be detected by CTA. In one donor even retrospective analysis of CTA was negative. Ten accessory arteries, 14 venous anomalies and 12 renal arteries stenosis due to atherosclerosis were diagnosed by CTA and could be confirmed by the operative report. Conclusion: CTA is sufficient for detection of hemodynamic relevant stenosis and vascular anatomy. Only one patient with a mild form of FMD was under estimated. Therefore, if the CTA shows slightest irregularities which are not typical for atherosclerotic lesions, further diagnostic work up by DSA might still be necessary.

  1. [Living donors for kidney transplantation: ethical and legal challenges].

    Mamzer-Bruneel, Marie-France; Fournier, Catherine; Legendre, Christophe


    Living donor kidney transplantation has developed very heterogeneously worldwide despite excellent results and without taking into account the context of global organ shortage. Such a heterogeneity highlights persistent ethical issues, whereas organ trafficking is emerging as an organized transplant tourism reinforcing the need for strong national legal frameworks. Despite its powerful regulation system, which ensures standardization, transparency and accountability of support for donation, France remains reluctant to enlarge the circle of legal donors, whereas it would be the first step to give a greater role to living organ donation.

  2. Medical community preferences concerning adult living related donor liver transplantation.

    Castaing, Denis; Azoulay, Daniel; Danet, Colette; Thoraval, Laurence; Tanguy Des Deserts, Catherine; Saliba, Faouzi; Samuel, Didier; Adam, René


    To assess acceptance and acceptable estimated mortality levels for right lobe adult-to-adult living related liver transplantation for the medical and allied professions. A paper questionnaire was sent to the physicians practicing with the French Graft Agency (Etablissement Français des Greffes) and to all nurses and ancillary staff of the Paul Brousse Hospital Hepatobiliary Center. Responses were received from surgeons: 38/73; internists specialized in hepatology: 44/120; nurses: 98/100; health care assistants: 45/86; others: 17/20. Acceptance of living donor transplantation is above average for all professional categories and indications may be extended including patients with cancer. Acceptable mortality for the donor was 4%, except among internists (0.7%). Currently, the real risk of mortality for the donor (1%) is lower. Acceptable mortality for the recipient was between 15 and 20%. Acceptance of adult living donor liver transplantation among health care professionals is clearly above average. Thus the psychological involvement of transplantation teams, which is very strong in such situations, should not hamper the development of this type of transplantation.

  3. Whooping cough in a renal transplant recipient.

    Garbiras, M; Shabaka, A; Calvo, N; Martin, L; Moreno, M A; Lopez de la Manzanara, V; Sanchez-Fructuoso, A I


    Whooping cough is a respiratory infection with a severity that varies with age, immune status, and probably with other factors such as the degree of exposure and the virulence of the organism. The most frequent microorganism responsible for whooping cough is Bordetella pertussis. We present the case of a 62-year-old renal transplant recipient presenting with typical and severe manifestations of whooping cough caused by B. pertussis.

  4. Emerging role of gasotransmitters in renal transplantation.

    Snijder, P M; van den Berg, E; Whiteman, M; Bakker, S J L; Leuvenink, H G D; van Goor, H


    Once patients with kidney disease progress to end-stage renal failure, transplantation is the preferred option of treatment resulting in improved quality of life and reduced mortality compared to dialysis. Although 1-year survival has improved considerably, graft and patient survival in the long term have not been concurrent, and therefore new tools to improve long-term graft and patient survival are warranted. Over the past decades, the gasotransmitters nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) have emerged as potent cytoprotective mediators in various diseases. All three gasotransmitters are endogenously produced messenger molecules that possess vasodilatory, anti-apoptotic, anti-inflammatory and anti-oxidant properties by influencing an array of intracellular signaling processes. Although many regulatory functions of gasotransmitters have overlapping actions, differences have also been reported. In addition, crosstalk between NO, CO and H2S results in synergistic regulatory effects. Endogenous and exogenous manipulation of gasotransmitter levels modulates several processes involved in renal transplantation. This review focuses on mechanisms of gas-mediated cytoprotection and complex interactions between gasotransmitters in renal transplantation.

  5. Cardiovascular disease in renal transplant recipients.

    McQuarrie, Emily P; Fellström, Bengt C; Holdaas, Hallvard; Jardine, Alan G


    Renal transplant recipients have a markedly increased risk of premature cardiovascular disease (CVD) compared with the general population, although considerably lower than that of patients receiving maintenance haemodialysis. CVD in transplant recipients is poorly characterised and differs from the nonrenal population, with a much higher proportion of fatal to nonfatal cardiac events. In addition to traditional ischaemic heart disease risk factors such as age, gender, diabetes and smoking, there are additional factors to consider in this population such as the importance of hypertension, left ventricular hypertrophy and uraemic cardiomyopathy. There are factors specific to transplantation such immunosuppressive therapies and graft dysfunction which contribute to this altered risk profile. However, understanding and treatment is limited by the absence of large randomised intervention trials addressing risk factor modification, with the exception of the ALERT study. The approach to managing these patients should begin early and be multifactorial in nature.

  6. Renal transplantation and polycystic: surgical considerations.

    Rodríguez-Faba, O; Breda, A; Villavicencio, H


    The indication and timing of nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPKD) remain controversial, especially in patients who are candidates to renal transplantation (RT). The main surgical options such as unilateral vs. bilateral nephrectomy, nephrectomy before vs. after RT, or simultaneous nephrectomy and transplantation, are herein discussed. Evidence acquisition of the best surgical management available for ADPKD in the context of kidney transplantation. Systematic literature review in PubMed from 1978 to 2013 was conducted. Articles selected included:randomized controlled trials and cohort studies. Furthermore, well designed ADPKD reviews were considered for this study. Laparoscopic nephrectomy in ADPKD is a safe procedure with an acceptable complication rate. Unilateral nephrectomy has advantages over the bilateral one regarding the perioperative complication rate. Although the timing of nephrectomy is controversial, it seems that simultaneous nephrectomy and renal transplantation does not increase surgical morbidity neither affect graft survival. Simultaneous nephrectomy and RT appears to be an acceptable alternative to conventional two-stage procedure without any increased morbidity, in the context of ADPKD. Furthermore, laparoscopic nephrectomy performed in experienced centres is a safe alternative to conventional approach. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

  7. Effect of donor age and parent-to-child transplant on living-related donor kidney transplantation: a single center's experience of 236 cases.

    Qiu, Jiang; Wang, Changxi; Liang, Xianwei; Chen, Guodong; Huang, Gang; Fu, Qian; Chen, Lizhong


    To study the impact of parent-to-child transplant and older donor age on recipients' post-transplant creatinine levels, a total of 236 patients who received living donor kidney transplantation were evaluated for kidney viability based on creatinine (Cr) level. Of the 236 pairings, 113 (48%) were parent-to-child followed by sibling transplants (66, 30%). Recipient Cr levels were significantly higher at 6 months and 3 years post-transplant in the parent-to-child transplants compared to other donor-recipient relationships. In addition, donor age (average age: 44.1 ± 11.5; range: 19-66) contributed to higher recipient post-transplant Cr levels (p parent-to-child transplant and older donor significantly increased the risk of elevated post-transplant Cr levels in recipients with an estimated odds ratios ranging from 3.46 (95% CI: 1.71-6.98) at 6 months to 8.04 (3.14-20.56) at 3 years post-transplant. Donor age significantly affected transplant survival as measured by higher recipient post-transplant Cr levels. In addition, parent-to-child transplant pairings, along with older donor age, significantly increased the risk of elevated post-transplant Cr levels in recipients.

  8. Efficacy of ultrasonography-guided renal biopsy for the evaluation of renal dysfunction following renal transplantation

    Kim, Young Jae; Choi, Chul Soon; Min, Seon Jeong; Lee, Gyung Kyu; Lee, Eil Seong; Kang, Ik Won; Bae, Sang Hoon [Hallym University College of Medicine, Chuncheon (Korea, Republic of)


    To evaluate the usefulness and complications of renal biopsy under ultrasonography-guidance in renal dysfunction after renal transplantation. Ultrasonography-guided renal biopsy was done in 47 patients with the transplanted kidney. The subjects consisted of 30 males and 17 females, age ranged from 16 to 66 years (average age=38 years). Biopsies were done once in 27 patients, twice in 17 patients, three times in 3 patients, a total of 70 biopsies. The success rate of renal biopsy for the accurate pathologic diagnosis and the incidence and types of complications following biopsy were evaluated. The success rate of renal biopsy for the accurate pathologic diagnosis was 96%(67/70). Pathologic diagnosis included 27 cases of acute rejection (39%), 8 cases of acute tubular necrosis (11%), 4 cases of acute rejection and acute tubular necrosis (6%), 4 cases of cyclosporin toxicity (6%), 4 cases of primary disease recurrence (6%), 4 cases of infection (6%) and others. Complications after renal biopsy included 15 cases of microscopic hematuria (21%), 1 case of gross hematuria with spontaneous cessation and 1 case of life threatening hemorrhage. Ultrasonography-guided renal biopsy is a safe and effective diagnostic method for the evaluation of renal dysfunction following renal transplantation.

  9. Donor lymphocyte infusion after allogeneic stem cell transplantation.

    Castagna, Luca; Sarina, Barbara; Bramanti, Stefania; Perseghin, Paolo; Mariotti, Jacopo; Morabito, Lucio


    Allogeneic stem cell transplantation (allo-SCT) is considered the cornerstone in the treatment of several malignant and not malignant hematological diseases. However, relapse of hematological disease after allo-SCT is considered the most challenging point in the field. The risk can be reduced through optimal patients, donor and disease selection before allo-SCT, but harnessing donor immune system is an appealing way to treat or avoid disease relapse. Donor lymphocyte infusion (DLI) is a simple and effective therapy after allo-SCT. In this paper, the efficacy of DLI will be analyzed in different hematological diseases, focusing also on their therapeutic or pre-emptive use.

  11. Comparison of renal function after donor and radical nephrectomy.

    Gazel, Eymen; Biçer, Sait; Ölçücüoğlu, Erkan; Yığman, Metin; Taştemur, Sedat; Çamtosun, Ahmet; Ceylan, Cavit; Ateş, Can


    Glomerular filtration rate (GFR) is directly proportionate to nephron reserves. In this respect, it is known that the patients who underwent radical nephrectomy due to renal tumor are under high risk of chronic kidney disease (CKD) in the long term. In this study, it was aimed to compare post-operative renal functions of patients who underwent radical nephrectomy due to renal malignancy and who underwent donor nephrectomy as renal donors, to observe whether renal failure process develops or not, and to determine the factors that affect post-operative renal functions. 70 patients who underwent donor nephrectomy as renal donors and 130 patients who underwent radical nephrectomy due to renal tumor were studied. When we divided the groups as those with a GFR of below 60 mL/min/1.73 m(2) and those with a GFR of above 60 mL/min/1.73 m(2), we observed that GFR values of patients who underwent radical nephrectomy had a significantly stronger tendency to stay below 60 mL/min/1.73 m(2) compared to patients who underwent donor nephrectomy (p < 0.001). When we divided the groups as those with a GFR of below 30 mL/min/1.73 m(2) and those with a GFR of above 30 mL/min/1.73 m(2), we observed that there were no patients in donor nephrectomy group whose GFR values dropped below 30 mL/min/1.73 m(2) and there was not a statistically significant difference between the groups (p = 0.099). If possible, nephron sparing methods should be preferred for patients to undergo nephrectomy because of the tumor without ignoring oncologic results and it should be remembered that patient's age and pre-operative renal functions may affect post-operative results in donor selection.

  12. Impaired renal allograft function is associated with increased arterial stiffness in renal transplant recipients

    Kneifel, M; Scholze, A; Burkert, A;


    It is important whether impairment of renal allograft function may deteriorate arterial stiffness in renal transplant recipients. In a cross-sectional study, arterial vascular characteristics were non-invasively determined in 48 patients with renal allograft using applanation tonometry and digital...... of large arteries S1 and small arteries S2 in renal transplant recipients (each p renal allograft (p ...-Wallis test between groups). It is concluded that impairment of renal allograft function is associated with an increased arterial stiffness in renal transplant recipients....

    A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0....

  14. Deceased donor kidney transplantation in autosomal dominant polycystic kidney disease: A single-center experience

    Vivek B Kute


    Full Text Available Renal transplantation (RTx has become the treatment of choice for end-stage renal disease (ESRD in autosomal dominant polycystic kidney disease (ADPKD, the most common genetic kidney disease. Because of the inheritable nature of this disease, live related donors might be avoided due to the fear of future appearance of polycystic disease. This retrospective singlecenter study was undertaken to evaluate patient/graft survival function vis-a-vis serum creatinine (SCr, rejection episodes and mortality in ADPKD vs matched control patients. Between 2000 and 2009, 18 (7.4% deceased donor renal transplant (DDRTx were performed for ESRD due to ADPKD. Diagnosis of ADPKD was established by family history and ultrasound. An individualized approach was applied for the need of pre-transplant nephrectomy. All recipients received rabbit-anti-thymocyte globulin induction and maintenance triple immunosuppression. Delayed graft function was observed in 33% patients, and 16% had biopsy-proven acute rejection. Over mean follow-up of 4.67 ± 2.2 years, patient and graft survival rates were 72.22% and 83.33%, with mean SCr (mg/dL of 1.44 ± 0.54, 1.78 ± 0.42 and 2.2 ± 0.6 at 1, 5 and 10 years. Overall, 44.4% (n-8 underwent pre-transplant nephrectomy. Infection and cardio/cerebrovascular events were the main causes of death. Patient, graft survival and acute rejection were similar between ADPKD and control group. DDRTx in ADPKD has acceptable patient and graft survival. Because of the inheritable nature of the disease, and unavailability of genetic linkage analysis as a routine, DDRTx is a viable option to avoid using unrelated donors.

  15. Acute torsion of a retroperitoneal renal transplant mimicking renal vein thrombosis.

    Winter, Thomas C; Clarke, Andrea Lynn; Campsen, Jeffrey


    When imaging a renal transplant, the combination of absent flow in the main renal vein and reversed diastolic flow in the intrarenal arteries is considered highly suggestive of renal vein thrombosis. We present a case of torsion of a transplant kidney presenting with identical findings. Renal transplant torsion in general is a rare entity, previously described only in intraperitoneally placed organs; this case is the first that we are aware of with torsion occurring in a retroperitoneally placed graft.

  16. Living-Donor Liver Transplant Follow-Up: A SingleCenter Experience.

    Laeeq, Syed Mudassir; Hanif, Farina M; Luck, Nasir Hassan; Mandhwani, Rajesh Kumar; Iqbal, Jawed; Mehdi, Syed Haider


    Liver transplant is a definite treatment of decompensated liver disease. Because of the shortage of livers from deceased donors, living-donor liver transplant is becoming more common. Here, we analyzed our clinical experience in the follow-up care of these patients. Liver transplant recipients seen at the Sindh Institute of Urology and Transplantation (Karachi, Pakistan) were included in this analysis. Baseline characteristics and follow-up events were recorded. Our study population included 76 liver transplant patients registered at our clinic. Median age was 42 years, with 62 patients (81.6%) being males. The most common indication of transplant was hepatitis C virus-related cirrhosis (42 patients; 55%), followed by hepatitis B-hepatitis D virus coinfection (8 patients; 10.5%). Anastomotic biliary stricture developed in 16 patients (21.1%),which required biliary stenting. Biliary leak developed in 5 patients (6.6%), and renal cell carcinoma developed in 1 patient. Two recipients died due to hepatitis C virus-related fibrosing cholestasis hepatitis and pulmonary com plications. Posttransplant diabetes mellitus developed in 36 (47.1%), hypertension in 17 (38.6%), and dyslipidemia in 19 patients (25%). Of 42 patients with hepatitis C virus infection, 26 were treated with pegylated interferon and ribavirin, of which 65.3% achieved sustained virologic response at 24 weeks. The other 16 patients received sofosbuvir com - bined with ribavirin for 24 weeks. A sustained virologic response at 12 weeks was achieved in 5 patients, with not yet determined results in the remaining patients. Seven patients were lost to follow-up. Hepatitis C-related cirrhosis was the most common indication for liver transplant, and infection recurrence was observed in our patients. Biliary anastomotic stricture formation was the most prevalent complication after transplant. As liver transplants are becoming more widely available for Pakistani patients at home and abroad, gastroenterologists and

  17. Long-term safety in living kidney donors for paediatric transplantation. Single-centre prospective study.

    Martin Benlloch, J; Román Ortiz, E; Mendizabal Oteiza, S

    There is enough evidence concerning the short-term safety of living donors after kidney transplantation. However, long-term complications continue to be studied, with a particular interest in young donors. Previous studies have been conducted in older donors for adult renal patients. We present a study of long-term complications in kidney donors for our paediatric population. We carried out a long-term donor study for the 54 living kidney-donor transplantations performed at our department from 1979 to June 2014. We monitored the glomerular filtration rate (GFR) on the basis of 24-hour urine creatinine clearance, 24-hour proteinuria and the development of arterial hypertension in the 48 donors who were followed up for more than one year. Only the 39 patients who were exclusively followed up by our department have been included in the results analysis. GFR through creatinine clearance was stable after an initial decrease. No proteinuria was observed in any of the cases. One patient developed chronic kidney disease (CKD), which resulted in a cumulative incidence of 2%. GFR below 60mL/min/1.73 m(2) was not reported in any other patients. Arterial hypertension was diagnosed in 25% of donors, 90% of which were treated with antihypertensives. Risk of CKD and hypertension in living kidney donors for paediatric recipients, who are carefully monitored throughout their evolution, is similar to that of the general population. Therefore, this technique appears to be safe in both the short and long term. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

    From a theoretical point of view, an alloimmune response can not take place, still some type of standard immunosuppression is used in about 60% of patients receiving kidney grafts from their monozygotic twins. We aimed at assessing clinical response in patients receiving renal grafts from a living monozygotic twin donor when no immunosuppressive therapy is used. This is a retrospective observational study of patients receiving kidney grafts from their monozygotic twins from 1969 to 2013. The following data were recorded: age, renal graft recipient's primary disease, renal function, renal survival and overall survival. Immunosuppressive therapy included a single intraoperative dose of methylprednisolone 500 mg and no maintenance immunosuppression. Five patients with kidney grafts from their monozygotic twins were dentified in our centre. Mean age at transplantation was 33 years (27-39). One-year overall survival and graft survival were 100%. Mean creatinine level was 0.96 ± 0.2 one year after transplantation, and 1.2 ± 0.37 mg/dl at most recent follow-up. Two patients died with a functional graft more than 15 years after kidney transplantation (causes were melanoma and cardiovascular event respectively). Follow-up was lost in a patient one year after transplantation. Two patients are alive with a functioning graft at 18 months and 42.5 years after transplantation respectively. Kidney transplantation from a living monozygotic twin is associated to outstanding clinical outcomes. Immunossuppresive therapy to suppress alloimmune response in probably unnecessary 11 zygosity has been confirmed. Copyright © 2015 The Authors. Published by Elsevier España, S.L.U.

    Morales, Enrique; Gutiérrez, Eduardo; Hernández, Ana; Rojas-Rivera, Jorge; Gonzalez, Esther; Hernández, Eduardo; Polanco, Natalia; Praga, Manuel; Andrés, Amado


    The shortage of organs is a major hurdle in kidney transplantation, and one solution to the problem is to extend the age of the donor. However, organs from older donors are often discarded due to the macroscopic appearance of the parenchyma or major vessels. On the other hand, a large number of elderly patients are potential candidates for kidney transplantation, while many kidneys from elderly deceased donors are discarded due to a lack of age-matched recipients. In addition, a large number are often discarded due to the lack of compatible recipients among elderly patients undergoing chronic dialysis. A possible solution to avoid this wastage of kidneys potentially suitable for transplantation could be the performance of preemptive kidney transplantation (PKT) in carefully selected elderly patients. PKT improves graft and patient survival compared to other renal replacement therapy options. There is no information about PKT in elderly patients receiving kidneys from elderly deceased donors. From 2007 to 2012, we performed a prospective observational study comparing 26 elderly patients receiving PKT with a control group of 26 elderly patients receiving a first transplant after prior dialysis. Mean age of recipients was 74.3±2.9 years and mean age of donors was 73.8±4.1 years. Induction immunosuppression was similar in both groups. Death-censored graft survival was 96% in the PKT group and 68% in the control group (p=0.02), at 5 years after transplantation. Immediate and delayed graft function occurred in 92% and 3.8%, respectively, of patients in the PKT group and 53% and 34.6% of patients in the control group (p=0.005). Acute rejection was significantly more frequent in PKT patients (23.1% vs 3.8%, p=0.043). At the end of follow-up time 35.5±20.1 months, the glomerular filtration rate was similar in both groups (42.2±11.7 vs 41.7±11.2ml/min, p-value=0.72). Patient survival was similar in the two groups. Elderly patients with end stage of renal disease non

    Post-transplant lymphoproliferative disorder (PTLD) is a complication of organ transplantation and immunosuppression. A 36-year-old woman with a history of renal transplantation visited the hospital complaining of headache and on pathology was diagnosed with cerebral PTLD manifesting as multiple rim enhanced masses in both hemispheres. We report here a case of post-transplant lymphoproliferative disorder involving the cerebrum occurring after renal transplantation, and describe the MRI findings for this patient

    Introduction: Delayed graft function due to ischaemia-reperfusion injury is a frequent complication in deceased donor renal transplantation. Experimental evidence indicates that remote ischaemic conditioning (RIC) provides systemic protection against ischaemia-reperfusion injury in various tissues.

    End-stage liver disease,due to cholestatic liver diseases with an autoimmune background such as primary biliary cirrhosis(PBC)and primary sclerosing cholangitis(PSC),is considered a good indication for liver transplantation.Excellent overall patient and graft outcomes,based mostly on the experience from deceased donor liver ransplantation(DDLT),have been reported.Due to the limited number of oraan donations from deceased donors in most Asian countries,living donor liver transplantation(LDLT)is the mainstream treatment for end-stage liver disease,including that resulting from PBC and PSC.Although the initial experiences with LDLT for PBC and PSC seem satisfactory or comparable to that with DLT,some aspects,including the timing of transplantation,the risk of recurrent disease,and its long-term clinical implications,require further evaluation.Whether or not the long-term outcomes of LDLT from a biologically related donor are equivalent to that of DDLT requires further observations.The clinical course following LDLT may be affected by he genetic background shared between the recipient and the living related donor.(C)2008 The WJG Press.All rights reserved.

  4. A single-center epidemiological study of BK virus infection and analysis of risk factors in patients with renal transplantation

    Ji-gang LI


    Full Text Available Objective To investigate the epidemiological characteristics of BK virus (BKV infection in living renal transplantation patients, and analyze the risk factors of BKV infection and BKV nephropathy (BKVN. Methods The BKV DNA load in urine and blood samples of 43 renal transplant recipients, who had received renal transplantation in 309 Hospital from Feb. 2012 to Feb. 2013, was determined at preoperative period and 0.5, 1, 3, 6, 9, 12 and 15 months after transplantation. Meanwhile, the biopsy of grafted kidney was performed in those patients with continuously elevated serum creatinine and those with higher BKV DNA load. Patients were divided into 3 groups as follows according to the test results: BK viruria group, BK viremia group and pathologically diagnosed BKVN group. Data of each group were then recorded, including gender, age, postoperative diabetes (PTDM, acute rejection (AR, delayed recovery of graft function (DGF, postoperative pulmonary infection, preoperative immune induction therapy, postoperative immunosuppressive regimen, and other information. The risk factors for postoperative BKV infection and BKVN were analyzed. Results After an average of 15-month follow-up, it was found that the incidence of BKV viruria was 46.5%, that of BKV viremia was 14.0%, and that of BKVN was 2.3%. Sixth month after transplantation was found to be the peak time of viruria and viremia. FK506 was significantly associated with viremia in living donor renal transplantation. The immunosuppressive regimen was the immune related independent risk factor for BK viremia developing BKVN after living renal transplantation. Conclusion The incidence of BK viremia and BKVN is lower in living donor renal transplantation than in cadaver renal transplantation, but that of viruria is similar in both groups. Immunosuppressive scheme based on FK506 is an immune related independent risk factor leading to BK viremia proceeding to BKVN in living donor kidney

    Morris-Stiff, G; Steel, A; Savage, P; Devlin, J; Griffiths, D; Portman, B; Mason, M; Jurewicz, W A


    Malignant melanoma represents the most common tumour responsible for donor-derived post transplantation malignancies. We report the varied presentation and outcome of three graft recipients (two kidney and hepatic) who developed metastatic melanoma following cadaveric organ transplantation from a single multiorgan donor. Two of the recipients presented with symptomatic metastatic lesions and the third patient, despite being carefully monitored, developed evidence of metastatic cutaneous melanoma. Two of the patients died as a direct result of their melanomas. The recipients of corneal and cardiac grafts remain disease-free. We conclude that despite careful screening, donor-derived tumours remain a not uncommon clinical entity. The identification of a lesion in one recipient should prompt immediate examination and investigation of the remaining recipients of multiorgan donations.

  6. Pre-transplant Evaluation of Donor Urinary Biomarkers can Predict Reduced Graft Function After Deceased Donor Kidney Transplantation.

    Koo, Tai Yeon; Jeong, Jong Cheol; Lee, Yonggu; Ko, Kwang-Pil; Lee, Kyoung-Bun; Lee, Sik; Park, Suk Joo; Park, Jae Berm; Han, Miyeon; Lim, Hye Jin; Ahn, Curie; Yang, Jaeseok


    Several recipient biomarkers are reported to predict graft dysfunction, but these are not useful in decision making for the acceptance or allocation of deceased donor kidneys; thus, it is necessary to develop donor biomarkers predictive of graft dysfunction. To address this issue, we prospectively enrolled 94 deceased donors and their 109 recipients who underwent transplantation between 2010 and 2013 at 4 Korean transplantation centers. We investigated the predictive values of donor urinary neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and L-type fatty acid binding protein (L-FABP) for reduced graft function (RGF). We also developed a prediction model of RGF using these donor biomarkers. RGF was defined as delayed or slow graft function. Multiple logistic regression analysis was used to generate a prediction model, which was internally validated using a bootstrapping method. Multiple linear regression analysis was used to assess the association of biomarkers with 1-year graft function. Notably, donor urinary NGAL levels were associated with donor AKI (P = 0.014), and donor urinary NGAL and L-FABP were predictive for RGF, with area under the receiver-operating characteristic curves (AUROC) of 0.758 and 0.704 for NGAL and L-FABP, respectively. The best-fit model including donor urinary NGAL, L-FABP, and serum creatinine conveyed a better predictive value for RGF than donor serum creatinine alone (P = 0.02). In addition, we generated a scoring method to predict RGF based on donor urinary NGAL, L-FABP, and serum creatinine levels. Diagnostic performance of the RGF prediction score (AUROC 0.808) was significantly better than that of the DGF calculator (AUROC 0.627) and the kidney donor profile index (AUROC 0.606). Donor urinary L-FABP levels were also predictive of 1-year graft function (P = 0.005). Collectively, these findings suggest donor urinary NGAL and L-FABP to be useful biomarkers for RGF, and support the use of

  7. Percutaneous Fixation of Anterior Column Acetabular Fracture in a Renal Transplant Recipient

    Halil Ceylan


    Full Text Available Renal transplantation, performed per million population, ranges from 30 to 60 in developed countries. The transplanted kidney is generally placed in iliac fossa; therefore the treatment procedure of the pelvic trauma in these patients should be selected carefully. The gold standard technique for the treatment of displaced acetabulum fractures is open reduction and internal fixation. Our patient had received a living-related-donor renal transplant due to chronic renal failure. In the second year of transplantation, she had been injured in a motor-vehicle accident, and radiographs showed a right acetabular anterior column fracture and left pubic rami fractures. The patient was treated with percutaneous fixation techniques and at one year of postoperative period there was no evidence of degenerative signs and the clinical outcome was good. Beside having the advantage of avoiding dissection through the iliac fossa by the standard ilioinguinal approach, percutaneous techniques, with shorter surgical time, decreasing soft tissue disruption, and the potential for early discharge from hospital might be ideal for a renal transplant recipient carrying a higher risk of infection. Percutaneous fixation of selected acetabular fractures in a renal transplant recipient would presumably have the potential to decrease the morbidity associated with traditional open surgical procedures.

  8. Treatment of advanced rectal cancer after renal transplantation

    Hai-Yi Liu; Xiao-Bo Liang; Yao-Ping Li; Yi Feng; Dong-Bo Liu; Wen-Da Wang


    Renal transplantation is a standard procedure for end-stage renal disease today. Due to immunosuppressive drugs and increasing survival time after renal trans-plantation, patients with transplanted kidneys carry an increased risk of developing malignant tumors. In this case report, 3 patients with advanced rectal can-cer after renal transplantation for renal failure were treated with anterior resection or abdominoperineal resection plus total mesorectal excision, followed by adjuvant chemotherapy. One patient eventually died of metastasized cancer 31 mo after therapy, although his organ grafts functioned well until his death. The other 2 patients were well during the 8 and 21 mo follow-up periods after rectal resection. We therefore strongly argue that patients with advanced rectal cancer should receive standard oncology treatment, including opera-tion and adjuvant treatment after renal transplantation. Colorectal cancer screening in such patients appears justified.

    Miguel Hidalgo Hospital in Aguascalientes is dependent from the Federal Secretary of Health and operates in integrity with State health system in Aguascalientes. It capacity is based on 132 censored beds and 71 no censored beds. Is considered a specialty hospital in the region of Bajío. Renal transplant program activity was initiated in 1990 and gives care for adult and pediatric population. Retrospective, comparative and longitudinal study to describe and analyze our experience. Data base and clinical charts of renal transplant recipients were reviewed. Age, gender, date of transplant, etiology of renal disease, type of donor, HLA compatibility and PRA, immunosuppressive therapy, acute rejection, serum creatinina, graft loss and mortality were registered. Statistical analysis included 2, unpaired Student T test and Kaplan-Meier survival analysis with Log Rank test. Cox Analysis was also done. 1050 renal transplants were done from November 1990 to June 2011. 50 were excluded because follow-up was not longer than 3 months. 1000 consecutive renal transplant patients from January 1995 to June 2011 were included for analysis. Patients were divided in 2 groups: group A transplanted January 1995 to December 2004; group B transplanted January 2005 to June 2011. Etiology for end stage renal disease is unknown in 61% of cases, 11% developed renal disease to diabetes mellitus. 93% patient survival was observed at median follow-up and 84.9% graft survival at median follow-up (6 years). Biopsy proven acute rejection in group A 19.9 vs. 10% in group B. Two haplotype matching shows 92% graft survival. Diabetic patients exhibit 73% graft survival vs. other as hypertension (87%). PRA >0 and serum creatinine > 2.0 mg/dL increase risk for graft loss according to Cox analysis. CONCLUSION. Results are comparable to international data. Importance of developing regional transplant centers is emphasized.

  10. Gastrointestinal complications in renal transplant recipients.

    Ponticelli, Claudio; Passerini, Patrizia


    Gastrointestinal complications are frequent in renal transplant recipients and can include oral lesions, esophagitis, peptic ulcer, diarrhea, colon disorders and malignancy. Oral lesions may be caused by drugs such as cyclosporine and sirolimus, by virus or fungal infections. Leukoplakia may develop in patients with Epstein-Barr virus (EBV) infection. The commonest esophageal disorder is represented by fungal esophagitis usually caused by candida. A number of patients may suffer from nausea, vomiting and gastric discomfort. These disorders are more frequent in patients treated with mycophenolate mofetil (MMF). Peptic ulcer is more rare than in the past. Patients with a history of peptic ulcer are particularly prone to this complication. Other gastroduodenal disorders are caused by cytomegalovirus (CMV) and herpes simplex infection. Diarrhea is a frequent disorder which may be caused by pathogen microorganisms or by immunosuppressive agents. The differential diagnosis may be difficult. Colon disorders mainly consist of hemorrhage, usually sustained by CMV infection, or perforation which may be caused by diverticulitis or intestinal ischemia. Colon cancer, anal carcinoma, and EBV-associated lymphoproliferative disorders are particularly frequent in transplant recipients. A particular gastric lymphoma called mucosa-associated lymphoid tissue (MALT) lymphoma may develop in renal transplant patients. It usually responds to the eradication of Helicobacter pylori.

  11. Microhematuria after renal transplantation in children.

    Butani, Lavjay; Berg, Gerre; Makker, Sudesh P


    The renal transplant (Tx) recipient is at risk for developing various complications including urolithiasis, the only manifestation of which may be hematuria. However, there are no data on the prevalence of microscopic hematuria in renal Tx recipients. The objective of our study was to determine the prevalence of microhematuria in our pediatric Tx patients and to investigate the causes of microhematuria. Records of all pediatric renal Tx recipients followed at our center from September 1999 to September 2000 were retrospectively reviewed; of the 21 patients, seven (33%) had persistent microscopic hematuria that was first noted 2.9 years post-Tx. Patients with and without hematuria had similar baseline characteristics. Only one patient had pre-existing hematuria that continued post-Tx. The etiology of hematuria in the other six patients was: recurrent IgA nephropathy (one patient), CMV nephritis (one patient), and unexplained (four patients). None had renal calculi or hypercalciuria. Three of the four patients with unexplained hematuria have chronic allograft nephropathy, and the fourth (original disease dysplasia) has hypocomplementemia. At their last follow-up, 5.3 years after onset of hematuria, all patients are alive with stable allograft function. In conclusion, microscopic hematuria is not uncommon in pediatric renal Tx recipients. While causes of post-Tx hematuria are diverse, stones are not commonly seen. Whether chronic allograft nephropathy per se can be implicated as a cause of hematuria remains to be determined. Renal biopsies should be considered at the onset of hematuria if proteinuria and/or deterioration in renal function are seen concomitantly, to look for recurrent or de novo glomerulonephritis.

  12. Eculizumab prevents recurrent antiphospholipid antibody syndrome and enables successful renal transplantation.

    Lonze, B E; Zachary, A A; Magro, C M; Desai, N M; Orandi, B J; Dagher, N N; Singer, A L; Carter-Monroe, N; Nazarian, S M; Segev, D L; Streiff, M B; Montgomery, R A


    Renal transplantation in patients with antiphospholipid antibodies has historically proven challenging due to increased risk for thrombosis and allograft failure. This is especially true for patients with antiphospholipid antibody syndrome (APS) and its rare subtype, the catastrophic antiphospholipid antibody syndrome (CAPS). Since a critical mechanism of thrombosis in APS/CAPS is one mediated by complement activation, we hypothesized that preemptive treatment with the terminal complement inhibitor, eculizumab, would reduce the extent of vascular injury and thrombosis, enabling renal transplantation for patients in whom it would otherwise be contraindicated. Three patients with APS, two with a history of CAPS, were treated with continuous systemic anticoagulation together with eculizumab prior to and following live donor renal transplantation. Two patients were also sensitized to human leukocyte antigens (HLA) and required plasmapheresis for reduction of donor-specific antibodies. After follow-up ranging from 4 months to 4 years, all patients have functioning renal allografts. No systemic thrombotic events or early graft losses were observed. While the appropriate duration of treatment remains to be determined, this case series suggests that complement inhibitors such as eculizumab may prove to be effective in preventing the recurrence of APS after renal transplantation.

    Background Multidetector-row CT (MDCT) has been evolving to the standard evaluating method of potential living donor in most centers, and can provide excellent details for selecting candidates and determining surgical technique.This study aimed to assess the value of MDCT in evaluation of the anatomy of living kidney donors and to reveal the prevalence of renal vascular variations in a Chinese population.Methods One hundred and four potential donors underwent MDCT and the data sets were post-processed for reformatted images with various techniques, such as maximum intensity projection (MIP), a volume-rendering technique (VR), and multiplanar reformation (MPR). Donor nephrectomies were performed on 97 candidates after MDCT evaluation with the findings during surgery constituting the standard of reference. Resulting MDCT images were compared with actual anatomy found during surgery. Results The MDCT images accurately displayed the anatomic structure of the main renal arteries and veins as well as the upper ureters, except in one case with horseshoe kidney. The prevalence of accessory arteries revealed in images was 27.2% (28/103) and early branching was found in 12.6% (13/103). Compared with findings during surgery, the detection of accessory arteries in MDCT images was 85.7% (6/7), and the detection of larger accessory arteries (>1.5 mm in diameter) was 100%. Detection of early branching was 100%.Conclusion MDCT helps accurately evaluate the renal anatomy of potential donors thus facilitating the planning of surgery.

  14. [New possibilities in kidney transplantation from live unrelated donors].

    Bosković, S


    The kidney transplantation, as a method of medical treatment, could not be developed faster in our country for many years. A number of demands for transplantation grows much faster than our modest capability. The similar, but in a rather smaller degree, this problem occurs in some other countries in the world. The main cause is: the organization of corpse collecting and the conservatism of doctors. The latter problem, in the countries of western hemisphere, is surpassed more easily by a doctor codex and a legal obligation that involves doctors actively in this process, which is not the case in our country. The organization of corpse collecting in some states of the USA is highly developed, but however it does not give sufficient number of organs for the cadaveric transplantation. New, additional possibilities are found: the taking of even organs (kidneys) from alive unrelated donors, spouses, which excludes the possibility of greed and gives, only in the USA, about 1.500 additional alive transplantations per year. The complementary medical attitude towards the increasing of number of cadaveric transplantations is: considerably freely taking of kidneys from cadavers without tissue compatibility, only with the compatibility of blood groups of ABO system. Since the immunological criteria, in our country, are very intensified by the Zagreb immunology group, e.g. from 75-100% for alive transplantation, or the minimum of 50% tissue compatibility for cadaveric transplantation, this old-fashioned attitude has considerably lowered the number of transplantations in our country.(ABSTRACT TRUNCATED AT 250 WORDS)

    In 2011, a pilot program for deceased organ donation was initiated in China. We describe the first successful series of liver transplants in the pilot program. From July 2011 to August 2012, our center performed 26 liver transplants from a pool of 29 deceased donors. All organ donation and allograft procurement were conducted according to the national protocol. The clinical data of donors and recipients were collected and summarized retrospectively. Among the 29 donors, 24 were China Category II donors (organ donation after cardiac death), and five were China Category III donors (organ donation after brain death followed by cardiac death). The recipients were mainly the patients with hepatocellular carcinoma. The one-year patient survival rate was 80.8% with a median follow-up of 422 (2-696) days. Among the five mortalities during the follow-up, three died of tumor recurrence. In terms of post-transplant complications, 9 recipients (34.6%) experienced early allograft dysfunction, 1 (3.8%) had non-anastomotic biliary stricture, and 1 (3.8%) was complicated with hepatic arterial thrombosis. None of these complications resulted in patient death. Notably, primary non-function was not observed in any of the grafts. With careful donor selection, liver transplant from deceased donors can be performed safely and plays a critical role in overcoming the extreme organ shortage in China.

  18. Acute cardiac tamponade: an unusual cause of acute renal failure in a renal transplant recipient.

    We report a case of slow graft function in a renal transplant recipient caused by uremic acute pericardial effusion with tamponade. Urgent pericardiocentesis was done with an improvement in blood pressure, immediate diuresis, and quick recovery of renal function back to baseline. Pericardial tamponade should be included in consideration of causes of type 1 cardiorenal syndrome in renal transplant recipients.

    End-stage renal disease (ESRD) is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). To analyze the outcome and prognostic factors of renal transplantation in patients with ESRD due to SLE from January 1986 to December 2013 in a single center. Fifty renal transplantations were performed in 40 SLE patients (32 female (80%), mean age at transplantation 36±10.4 years). The most frequent lupus nephropathy was type IV (72.2%). Graft failure occurred in a total of 15 (30%) transplantations and the causes of graft failure were chronic allograft nephropathy (n=12), acute rejection (n=2), and chronic humoral rejection (1). The death-censored graft survival rates were 93.9% at 1 year, 81.5% at 5 years, and 67.6% at the end of study. The presence of deceased donor allograft (P=0.007) and positive anti-HCV antibodies (P=0.001) negatively influence the survival of the renal transplant. The patient survival rate was 91.4% at the end of the study. Recurrence of lupus nephritis in renal allograft was observed in one patient. Renal transplantation is a good alternative for renal replacement therapy in patients with SLE. In our cohort, the presence of anti-HCV antibodies and the type of donor source were related to the development of graft failure.

  3. Massive Ascites in a Renal Transplant Patient after Laparoscopic Fenestration of a Lymphocele

    Shohei Kawaguchi


    Full Text Available Retroperitoneal lymphocele is a common complication of renal transplantation. Here, we report the case of a 67-year-old woman with massive ascites after fenestration surgery for a lymphocele that developed following renal transplantation. She had been on continuous ambulatory peritoneal dialysis for 9 years. Living donor renal transplantation was performed and an intrapelvic lymphocele subsequently developed. The lymphocele did not resolve after aspiration therapy; therefore, laparoscopic fenestration was performed. Although the lymphocele disappeared, massive ascites appeared in its stead. Half a year later, the ascites was surgically punctured, which then gradually resolved and disappeared 6 weeks later. Aspiration therapy should be considered in patients on long-term peritoneal dialysis, although laparoscopic fenestration is safe and effective.

  4. Acute Rejection after Human Renal Transplantation

    Ana Roussoulières


    Full Text Available Genes involved in acute rejection (AR after organ transplantation remain to be further elucidated. In a previous work we have demonstrated the under-expression of VE-Cadherin by endothelial cells (EC in AR following murine and human heart transplantation. Serial sections from 15 human kidney Banff-graded transplant biopsies were examined for the presence of VE-Cadherin and CD34 staining by immunohistochemistry (no AR (n=5, AR grade IA (n=5, or AR grade IIA (n=5. Quantification of peritubular EC staining were evaluated and results were expressed by the percentage of stained cells per surface analysed. There was no difference in CD34 staining between the 3 groups. VE-Cadherin expression was significantly reduced in AR Grade IIA when compared to no AR (P=.01 and to AR grade IA (P=.02. This study demonstrates a reduced VE-Cadherin expression by EC in AR after renal transplantation. The down-regulation of VE-Cadherin may strongly participate in human AR.

    Atalan, Hakan K; Gucyetmez, Bulent; Aslan, Serdar; Yazar, Serafettin; Polat, Kamil Y


    There are many risk factors for postoperative acute kidney injury in liver transplantation. The aim of this study is to investigate the risk factors for postoperative acute kidney injury in living donor liver transplantation recipients. 220 living donor liver transplantation recipients were retrospectively evaluated in the study. According to the Kidney Disease Improving Global Outcomes Guidelines, acute kidney injury in postoperative day 7 was investigated for all patients. The patient's demographic data, preoperative and intraoperative parameters, and outcomes were recorded. Acute kidney injury was found in 27 (12.3%) recipients. In recipients with acute kidney injury, female population, model for end-stage liver disease score, norepinephrine requirement, duration of mean arterial pressure less than 60 mmHg, the usage of gelatin and erythrocyte suspension and blood loss were significantly higher than recipients with nonacute kidney injury (for all p5 mL kg-1 and duration of MAP less than 60 mmHg ≥5.5 minutes respectively (for all p<0.05). In living donor liver transplantation recipients, serum tacrolimus levels, intraoperative blood loss, hypotension period and the usage of gelatin may be risk factors for acute kidney injury in the early postoperative period.

    Exposition of results obtained from the review of the surgical complications found in a series of 479 renal transplantations performed between 1978 and 1992 in our centre, although some of them lack clinical relevance. There was fluid accumulation in 69 patients, distributed between 31 perirenal haematoma. 17 lymphocele, 13 urinoma, 5 perirenal abscesses and 3 mixed. 27.7% required no action. Frequency of renal rupture was 18 cases, 9 due to acute rejection and 9 to vascular thrombosis. Incidence of urinary obstruction was 4.8% with 5.8% of urinary fistula. With regard to the surgical wound, 9 infections, 7 haematomas, 1 eventration and 1 necrotizing fasciitis were observed. Vascular complications consisted in 10 arterial thrombosis, 10 venous thrombosis, 5 mixed thrombosis and 31 arterial stenosis. Treatment instituted for the various cases, its evolution, and an statistical study of risk factors are illustrated.

    Full Text Available Aims. To examine the outcome of potential live kidney donors (PLKD assessment program at Christchurch Hospital and, also, to review findings of Computed Tomographic (CT renal angiograms that led to exclusion in the surgical assessment. Methods. Clinical data was obtained from the database of kidney transplants, Proton. Radiological investigations were reviewed using the hospital database, Éclair. The transplant coordinator was interviewed to clarify information about PLKD who did not proceed to surgery, and a consultant radiologist was interviewed to explain unfavorable findings on CT renal angiograms. Results. 162 PLKD were identified during the period January 04–June 08. Of those, 65 (40% proceeded to have nephrectomy, 15 were accepted and planned to proceed to surgery, 13 were awaiting further assessment, and 69 (42.5% did not proceed to nephrectomy. Of the 162 PLKD, 142 (88% were directed donors. The proportion of altruistic PLKD who opted out was significantly higher than that of directed PLKD (45% versus 7%, P=0.00004. Conclusions. This audit demonstrated a positive experience of live kidney donation at Christchurch Hospital. CT renal angiogram can potentially detect incidental or controversial pathologies in the kidney and the surrounding structures. Altruistic donation remains controversial with higher rates of opting out.

  9. [Pregnancy in patients with renal transplantation].

    Chocair, P R; Ianhez, L E; de Paula, F J; Sabbaga, E; Arap, S


    From 1969 to 1987, 35 pregnancies occurred in 31 women with renal transplant. Four of them were still pregnant when this study was concluded. There was one ectopic pregnancy. All patients received azathioprine and prednisone. In the majority of patients the glomerular filtration rate increased in a way similar to normal pregnant women. In five cases there was a progressive loss in renal function. In four of them this was attributed to preexistent renal damage. No toxemia occurred. Anemia developed during 11 pregnancies and blood transfusion was required for five women. Four patients had urinary tract infection which was easily controlled with antibiotics. One patient had severe arterial hypertension, secondary to chronic rejection. One patient developed jaundice reverted with reduction in azathioprine doses. One woman died of septicemia secondary to fetal death, during the 6th month of pregnancy. Twenty children were born with no abnormalities, although many of them were underweighted. Two thirds of pregnancies were delivered by cesarean section. No harm to the pelvic allograft occurred in vaginal deliveries. There have been 4 abortions (2 of them were induced with no medical indication). Four pregnancies (26 to 39 gestational weeks) ended in stillborn babies: the mothers had impaired renal function associated with hypertension and proteinuria. One newborn died of pulmonary infection two days after delivery. Another was born with microcephaly and polydactilia and survived 6 years. No breast feeding was allowed.

  17. Hypophosphatemia after Right Hepatectomy for Living Donor Liver Transplantation

    Kelly W Burak


    Full Text Available Hypophosphatemia has been described in patients undergoing right hepatectomy for liver cancer and in living donors for liver transplantation who also received total parenteral nutrition. At the study centre, significant hypophosphatemia (0.36 mmol/L or less requiring intravenous replacement was seen in two of the first nine living donors for adult-to-adult liver transplantation. To determine the frequency of hypophosphatemia in living donors, the authors obtained phosphate levels on stored serum samples from postoperative days 0, 1, 3 and 7 in all nine patients, none of whom were on total parenteral nutrition. Within the first week, hypophosphatemia developed in 55.6% of patients and phosphate levels returned to normal by day 7 in all nine patients. One patient had normal phosphate levels during the first week, but had profound hypophosphatemia (0.32 mmol/L on day 14 when he presented with a Staphylococcus aureus infection of a bile collection and significant hypoxemia. The extent of hepatectomy and the rate of liver regeneration, estimated by baseline and postoperative day 7 volumetric computed tomography scans, did not correlate with the development of hypophosphatemia. In conclusion, hypophosphatemia is common in living donors undergoing right hepatectomy and may be associated with complications. All living donors should be monitored for the development of hypophosphatemia during the first two postoperative weeks.

  18. Ascorbic acid against reperfusion injury in human renal transplantation.

    Norio, Karri; Wikström, Mårten; Salmela, Kaija; Kyllönen, Lauri; Lindgren, Leena


    The cadaveric renal graft is exposed to ischaemic injury during preservation and to oxidative damage during reperfusion. Both these mechanisms are known to cause cell damage, which may impair graft function. Reperfusion injury (RPI) is mediated by reactive oxygen species (ROS). Ascorbic acid (AA) is a potent physiological extracellular scavenger of ROS. We perfused 31 renal grafts immediately before implantation with a solution of Euro-Collins containing 0.5 mg/ml of AA to diminish RPI. From every donor, the contralateral kidney served as a control. The control grafts were perfused with the same perfusion as those of the AA group, only without the AA substitution. We assessed the effect of AA by recording serum creatinine, creatinine clearance, initial graft function and early rejections. The incidence of delayed graft function (DGF) was 32% in the AA group, and 29% in the control group. Other parameters were also similar in both groups, except for the length of DGF, which showed a trend towards a shorter duration in the AA group. The pre-operative systemic AA concentration was significantly ( P=0.01) lower in the haemodialysis patients than in those on peritoneal dialysis. In conclusion, this clinical study could not demonstrate significant benefits of AA in renal transplantation.

  19. Early experience with lung transplantation using donors after cardiac death.

    Mason, David P; Murthy, Sudish C; Gonzalez-Stawinski, Gonzalo V; Budev, Marie M; Mehta, Atul C; McNeill, Ann M; Pettersson, Gösta B


    Lung transplantations that utilize donor organs after cardiac death (DCD) can substantially increase the number of available allografts for waiting recipients. Unfortunately, reported clinical outcomes are limited and widespread acceptance is slow. To further examine the potential of this modality, the results of 4 patients transplanted with DCD organs, implementing a protocol of controlled organ retrieval (Maastricht Classification III), were reviewed. There were no operative deaths; extracorporeal membrane oxygenation was required in 1 patient secondary to severe primary graft dysfunction. Three patients are alive and well at 4, 15 and 21 months; 1 patient died at 34 months with bronchiolitis obliterans syndrome, in part attributable to medication non-compliance.

  20. Clinical Experience of Total Intravenous Anesthesia in 77 Renal Transplant Patients

    Pinar Ergenoglu


    Full Text Available Purpose:Renal transplantation significantly improves quality of life compared to hemodialysis in patients with end-stage renal failure. In end-stage renal failure anesthetic technique should be planned carefully, due to changes in volume distribution, drug metabolism, excretion. Results of total intravenous anesthesia, inhalation anesthesia, regional techniques are being investigated. Aim of this study was to present our experience in total intravenous anesthesia in 77 patients, who underwent live and cadaveric donor renal transplantation at Baskent University Faculty of Medicine Adana Teaching and Research Center. Material and Methods:Induction of anesthesia was performed with propofol(2mg/kg and fentanyl(1μg/kg, and rocuronium bromide(0.4-0.5mg/kg was given before intubation. Anesthesia was maintained with total intravenous anesthesia(propofol,50 mcg/kg/min; remifentanil,0.25 mcg/kg/min infusion. Intraoperative fluid, urine volumes were recorded. For preemptive multimodal analgesia, pre-incisional intravenous paracetamol(15mg/kg, intramuscular morphine(0.1mg/kg were given. Postoperative analgesia was maintained with intravenous patient-controlled analgesia(meperidine 10 mg bolus, with a lockout time of 20 minutes. Postoperative pain was recorded using Visual Analogue Scale, level of sedation was assessed by Ramsey Sedation Scale. Results:Study included 64(83.1% live donor transplantations and 13(16.9% cadaveric donor transplantations. Mean total fluid administration was similar between live and cadaveric donor kidney transplantation patients however mean intraoperative urine output was significantly higher in live donor kidney transplantation patients(p<0.001. 57.1% of patients had no pain at 5. minutes postoperatively(Visual Analog Scale Score=0, at 15. minutes postoperatively mean visual analog scale score was 2.6 and the first analgesic requirements were recorded at 39.6 minutes.

    The outcomes of transplanted kidney recipients from "transplant tourism" have been reported to be alarming. The present study was an attempt to examine the results of renal patients from the Ivory Coast transplanted abroad returning home for follow-up. This retrospective analysis includes renal patients from the Ivory Coast transplanted abroad between 1995 and 2009 and followed up by our nephrology clinic. We collected pre- and posttransplant parameters for statistical analyses. The 16 patients had a median age of 48 years (range = 32.5-53.75). The median age of kidney donors was 44 years (range = 30.75-51.25). Initial kidney disease was hypertension in 10 patients (62.5%) and diabetes in three patients (18.8%). They received organs from living donors (37.5% related [LRD] and 37.5% unrelated [LURD]). Initial immunosuppression consisted of induction (72.7%), tacrolimus (75%), and mycophenolate mofetil (100%). Two patients (12.5%) experienced late acute rejections, resulting in graft loss. The overall graft survival was 93% at 1 year and 80% at 5 years. Five patients died over the study period, corresponding to an overall mortality rate of 9.25/100 patient-years. The overall median patient survival was 6.25 years (range = 4.19-7.58). Patient survivals at 1 and 5 years were 93% and 53%, respectively. No factors seemed to influence survival (either graft or patient) upon multivariate analysis. Comparison between LRD and LURD recipients revealed no statistical difference among posttransplant characteristics and survivals. Mortality of renal patients from the Ivory Coast transplanted abroad is high. Financial exhaustion after transplantation renders follow-up precarious. A local kidney transplantation program in the Ivory Coast appears more urgent than ever. Copyright © 2010 Elsevier Inc. All rights reserved.

  2. Interventional radiological treatment of renal transplant complications: A pictorial review

    Lezzi, Roberto; La, Torre Michele fabio; Santoro, Marco; Dattesi, Robrta; Nestola, Massimiliano; Posa, Alessandro; Romagnoli, Jacopo; CItterio, Franco; Bonomo, Lorenzo [' A. Gemelli' Hospital - Catholic University, Rome (Italy)


    Renal transplantation is the treatment of choice for patients with chronic renal failure, which produces a dramatic improvement in the quality of life and survival rates, in comparison to long-term dialysis. Nowadays, new imaging modalities allow early diagnosis of complications, and thanks to the recent developments of interventional techniques, surgery may be avoided in most cases. Knowledge in the types of renal transplant complications is fundamental for a correct pre-operative planning. In this article, we described the most common or clinically relevant renal transplant complications and explained their interventional management.

  3. The effects of kidney transplantation on sleep, melatonin, circadian rhythm and quality of life in kidney transplant recipients and living donors.

    Sleep disturbance is an important medical problem in patients with end-stage renal disease. It might be related to the disruption of the body's circadian clock since nocturnal levels of its key biomarker melatonin are markedly reduced. We aimed at investigating whether a change in renal function due to kidney transplantation or donation would modify sleep, melatonin levels, circadian rhythmicity, and quality of life in kidney transplant recipients (KTR) and living donors (LD). In KTR, we assessed saliva melatonin concentrations, sleep quality and daytime sleepiness prior to and at 2 weeks and 3 months after transplantation. In LD, we assessed these parameters prior to and at 3 months after donation. We additionally assessed 24-hour core body temperature (cBT), 24-hour blood pressure profile, and quality of life (QoL) prior to and 3 months after transplantation. Twenty-three KTR and 23 LD completed the study. Regarding sleep, the amount of nighttime awake minutes tended to be reduced in recipients after transplantation (p = 0.05). Nocturnal melatonin concentrations did not change with transplantation or donation. Blood pressure dipping profile and the two circadian markers dim-light melatonin onset and time of core body temperature minimum did not change. Nevertheless, KTR reported that daytime sleepiness and QoL had improved. Objectively nocturnal sleep quality marginally improved after transplantation. Subjectively patients reported improved QoL and daytime sleepiness scores. Changes in renal function were not associated with modified melatonin secretion or circadian rhythmicity.

  4. Genetic diversity through human leukocyte antigen typing in end-stage renal disease patients and prospective donors of North India

    Mohit Chowdhry


    Full Text Available As the incidence of end-stage renal disease (ESRD is rapidly increasing, the demand for dialysis and transplantation has dramatically increased, which has led to concerns about the availability and equitable allocation of kidneys for transplantation. The distribution of HLA-A, B and DR alleles in 148 renal transplant recipients and 191 live related prospective donors from 2009 to 2010 were analyzed. Allele frequencies and haplotype frequencies were calculated in recipients and donors. The prospective donors were further analyzed on the basis of their relationship to the patients and according to the sex ratio. A significant female preponderance was noted in the prospective donor population, most of whom were either siblings or parents of the recipients. On the contrary, the recipient population predominantly comprised of males. The most frequent HLA-A, HLA-B, HLA-DRB1 alleles in renal transplant patients were HLA-AFNx0111, AFNx0102, AFNx0101, AFNx0124; HLA-BFNx0135, BFNx0140, BFNx0144, BFNx0115, BFNx0152, and HLA-DRB1FNx0115, DRB1FNx0107, DRB1FNx0113, DRB1FNx0111 respectively. The most frequent HLA-A, HLA-B, HLA-DRB1 alleles in prospective donors were HLA-AFNx0102, AFNx0111, AFNx0133, AFNx0124; HLA-BFNx0135, BFNx0144, BFNx0140, BFNx0115 and HLA-DRB1FNx0115, DRB1FNx0107, DRB1FNx0111, DRB1FNx0113 respectively. AFNx0111-BFNx0135, AFNx0102-DRB1FNx0115, BFNx0140-DRB1FNx0115 were the most common HLA A-B , HLA A-DR, HLA B-DR haplotypes respectively in renal transplant patients, whereas, AFNx0111-BFNx0135, AFNx0111-DRB1FNx0115, BFNx0144-DRB1FNx0107 were the most common haplotypes in renal donors. In three locus haplotype, HLA-AFNx0102-BFNx0140-DRB1FNx0115 was the most frequent haplotype in patients, whereas, in prospective renal donors HLA-AFNx0133-BFNx0144-DRB1FNx0107 was the most frequent haplotype.

  5. De novo glomerular diseases after renal transplantation.

    Ponticelli, Claudio; Moroni, Gabriella; Glassock, Richard J


    Glomerular diseases developing in the kidney allograft are more often recurrences of the original disease affecting the native kidneys. However, in an undefined number of cases de novo, glomerular diseases unrelated to the original disease in the native kidneys can develop in the transplanted kidney. The clinical presentation and histologic features of de novo diseases are often similar to those features observed in patients with primary or secondary GN in the native kidneys. However, in transplanted kidneys, the glomerular, vascular, and tubulointerstitial changes are often intertwined with structural abnormalities already present at the time of transplant or caused by antibody- or cell-mediated allograft rejection, immunosuppressive drugs, or superimposed infection (most often of a viral nature). The pathophysiology of de novo glomerular diseases is quite variable. In rare cases of de novo minimal change disease, circulating factors increasing the glomerular permeability likely participate. Maladaptive hemodynamic changes and tissue fibrosis caused by calcineurin inhibitors or other factors may be involved in the pathogenesis of de novo FSGS. The exposure of cryptic podocyte antigens may favor the development of de novo membranous nephropathy. Many cases of de novo membranoproliferative GN are related to hepatitis C virus infection. Patients with Alport syndrome lacking antigenic epitopes in their glomerular basement membrane may develop antibodies against these glomerular basement membrane antigens expressed in the transplanted kidney. Infection may cause acute GN to have a heterogeneous clinical presentation and outcome. De novo pauci-immune GN in renal transplant is rare. Preexisting or acquired intolerance to glucose may, in the long term, cause diabetic nephropathy. The prognosis of de novo diseases depends on the type of GN, the severity of lesions caused by the alloimmune response, or the efficacy of immunosuppressive therapy. In most cases, the management

    To establish a simple and stable cervical ectopic renal transplantation rat model that increase surgical successful rate. A total of 208 male inbred Wistar rats (weighing 220-260 g) were randomly served as donors and recipients. The graft consisting of kidney, renal vein (RV) and renal artery (RA) was obtained, and perfused in situ. The donor RA was end-to-end anastomosed to the recipient left common carotid artery (CCA) by using of "sleeve" anastomosis, and the donor RV to the recipient right external jugular vein by using of "cuff" technique. The distal end of the ureter was brought out to form cervical cutaneous stomas. A total of 104 ectopic renal transplantations were performed in rats, including stages of the pre-experiment (62 operations) and experiment (42 operations). The success rates of the two stages were 80.6% and 95.2%, respectively. The causes of failure in the pre-experimental stage were anesthesia accidents, thrombosis of the arterial anastomosis, massive hemorrhage, air embolism and phlebemphraxis. In the experimental stage, 2 rats died due to late anastomotic hemorrhage and thrombosis. The remaining 40 transplanted kidney survived more than 6 months. The time for surgery was (40 +/- 6) minutes, the average time for donor surgery was (20 +/- 5) minutes, the preparation time for the graft was (8 +/- 2) minutes, the operative time for the recipient was (18 +/- 3) minutes, including the time for the arterial anastomosis (5 +/- 2) minutes and venous anastomosis (2 +/- 1) minutes, the cold ischemia time of graft was (15 +/- 3) minutes. The cervical ectopic renal transplantation technique has the advantages of easy-and fast-to-perform, shorter operation and cold ischemia time, higher successful rate.

    AIM:To evaluate the relationship between donor safety and remnant liver volume in right lobe living donor liver transplantation (LDLT).METHODS:From July 2001 to January 2009,our liver transplant centers carried out 197 LDLTs.The clinical data from 151 cases of adult right lobe living donors (not including the middle hepatic vein) were analyzed.The conditions of the three groups of donors were well matched in terms of the studied parameters.The donors' preoperative data,intraoperative and postoperative data were calculated for the three groups:Group 1 remnant liver volume (RLV) < 35%,group 2 RLV 36%-40%,and group 3 RLV > 40%.Comparisons included the different remnant liver volumes on postoperative liver function recovery and the impact of systemic conditions.Correlations between remnant liver volume and post-operative complications were also analyzed.RESULTS:The donors' anthroposomatology data,operation time,and preoperative donor blood test indicators were calculated for the three groups.No significant differences were observed between the donors' gender,age,height,weight,and operation time.According to the Chengdu standard liver volume formula,the total liver volume of group 1 was 1072.88 ± 131.06 mL,group 2 was 1043.84 ± 97.11 mL,and group 3 was 1065.33 ± 136.02 mL.The three groups showed no statistically significant differences.When the volume of the remnant liver was less than 35% of the total liver volume,the volume of the remnant had a significant effect on the recovery of liver function and intensive care unit time.In addition,the occurrence of complications was closely related to the remnant liver volume.When the volume of the remnant liver was more than 35% of the total liver volume,the remnant volume change had no significant effect on donor recovery.CONCLUSION:To ensure donor safety,the remnant liver volume should be greater than the standard liver volume (35%) in right lobe living donor liver transplantation.

  8. Laboratorial evaluation of potential donors of organs and tissues for transplantation

    Quinidia Lúcia Duarte de Almeida Quithé de Vasconcelos


    Full Text Available The objective of this study was to describe the laboratorial complementary evaluation in potential donors of organs and tissues for transplantation. It is a descriptive, quantitative study made in six hospitals in Natal/ Rio Grande do Norte, Brazil, between August/2010 to February/2011. The sample consisted of 65 potential donors and a checklist type instrument was used. Information was collected and analyzed using descriptive statistics. From a total number of donors, 89.2% had blood typing, 80.0% hematological tests and verification of the electrolytes. As for the functions, 70.8% had tests for verification of pulmonary function and 80.0% for renal function. From the alterations detected, 69.2% presented hyperoxia, 66.2% leukocytosis, 47.7% hypernatremia, 43.1% increase in the creatine kinase, 10.0% with positive serology. Relevant tests were not made. It is essential to assess potential donors to detect and treat alterations, ensuring the quality of the organs and the quality of the transplantation.

  9. Living donor transplantation--the real gift of life. Procurement and the ethical assessment.

    Banasik, Mirosław


    It has been observed during the past 10-15 years a greater disparity between the supply of kidneys for transplantation and the demand of patients on waiting lists. The number of cadaveric kidneys available for transplantation have not increased in many countries. Countries and their societies are faced with a choice, let patients with the end- stage renal disease stay on, dialysis giving a faster death and a lower quality of life, or decide to introduce the more active living donation program. There are countries, historically Scandinavian countries, the U.S.A. and U.K., which decided to change medical, social and ethical attitudes to help their citizens and patients on dialysis. For many other countries approval of the new approach of their donation seems to cause difficulties. The main problem for medical staff is the principle Primum non nocere (First do no harm), removal of a living kidney conflicts with this principle. From the other point of view is the human right of an individual to autonomy for donation of a kidney. The donor is completely informed for the risks involved in donation of a kidney to an awaiting recipient. The donors reasons for donation of the kidney must be understood and family pressure excluded. Where is the borderline between the paternalistic approach of the medical personnel preventing the altruistic attitude of the donor? How far is the role of the medical staff to extend in the assessment of the altruistic nature and goodwill of the donors?

  10. Cryptococcal meningitis presenting as sinusitis in a renal transplant recipient.

    Iyer, S P; Movva, K; Wiebel, M; Chandrasekar, P; Alangaden, G; Carron, M; Tranchida, P; Revankar, S G


    Cryptococcal meningitis is a relatively common invasive fungal infection in immunocompromised patients, especially in solid organ transplant recipients. Clinical presentation typically includes fever, headache, photophobia, neck stiffness, and/or altered mental status. Unusual presentations may delay diagnosis. Therapy is challenging in renal transplant patients because of the nephrotoxicity associated with amphotericin B, the recommended treatment. We present a case of cryptococcal meningitis in a renal transplant recipient presenting as acute sinusitis with successful treatment using fluconazole as primary therapy.

  11. Local graft irradiation in renal transplant rejection

    Kawamura, Masashi; Kataoka, Masaaki; Itoh, Hisao (Ehime Univ., Matsuyama (Japan). School of Medicine)


    From 1977 to 1988, of 142 renal transplantations, seven recipients (4.9%) received local graft irradiation following rejective reaction refractory to antirejection medical managements. Concurrent with the administration of pulsed high dose methylprednisolone and other antirejection medical managements, the graft was irradiated with a total dose of 6.0 Gy-150 cGy per fraction every other day at the midplane of the graft using two opposing portals of 4MX Linac. The fields were defined by palpation and echography. All patients had improvements in serum creatinine on the 10th day after beginning the irradiation. Four patients with peripheral lymphocytosis during the irradiation combined with pulsed high dose methylprednisolone improved in renal functions. On the other hand, out of 3 patients with lymphcytopenic changes, in two the transplanted graft was removed due to deteriorations, and the other patient is currently suffering from chronic rejection. Local graft irradiation can be useful in maintaining a rejective graft and reversing its functions in some patients whose rejective reaction failed to respond to the antirejection medical managements.

  12. Routine intraoperative stenting for renal transplant recipients.

    Wilson, Colin H; Bhatti, Aftab A; Rix, David A; Manas, Derek M


    Major urological complications (MUCs) after kidney transplantation contribute to patient morbidity and compromise graft function. Ureteric stents have been successfully used to treat such complications and a number of centers have adopted a policy of universal prophylactic stenting, at the time of graft implantation, to reduce the incidence of urine leaks and ureteric stenosis. In conjunction with the Cochrane Renal Group we searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, reference lists of articles, books and abstracts and contacted companies, authors and experts to identify randomized controlled trials examining the use of stents in renal transplantation. The primary outcome was the incidence of MUCs and data on this statistic was pooled and analyzed using a random effects model. Seven randomized controlled trials (1154 patients) of low or moderate quality were identified. The incidence of MUCs was significantly reduced (relative risk [RR] 0.24; 95% CI: 0.07 - 0.77; P=0.02; number needed to treat = 13) by prophylactic ureteric stenting. Urinary tract infections were more common in stented patients (RR 1.49), unless the patients were prescribed 480 mg cotrimoxazole once daily. With this antibiotic regime the incidence of infection was equivalent between the two groups (RR 0.97). Stents appeared generally well tolerated, although trials using longer stents (> or = 20 cm) for longer periods of time (>6 weeks) reported more problems with encrustation and migration. Universal prophylactic stenting reduces the incidence of MUCs and should be recommended on the basis of currently available randomized controlled trials.

    The European Best Practice Guideline group (EBPG) issued guidelines on the evaluation and selection of kidney donor and kidney transplant candidates, as well as post-transplant recipient care, in the year 2000 and 2002. The new European Renal Best Practice board decided in 2009 that these guidelines needed updating. In order to avoid duplication of efforts with kidney disease improving global outcomes, which published in 2009 clinical practice guidelines on the post-transplant care of kidney transplant recipients, we did not address these issues in the present guidelines.The guideline was developed following a rigorous methodological approach: (i) identification of clinical questions, (ii) prioritization of questions, (iii) systematic literature review and critical appraisal of available evidence and (iv) formulation of recommendations and grading according to Grades of Recommendation Assessment, Development, and Evaluation (GRADE). The strength of each recommendation is rated 1 or 2, with 1 being a 'We recommend' statement, and 2 being a 'We suggest' statement. In addition, each statement is assigned an overall grade for the quality of evidence: A (high), B (moderate), C (low) or D (very low). The guideline makes recommendations for the evaluation of the kidney transplant candidate as well as the potential deceased and living donor, the immunological work-up of kidney donors and recipients and perioperative recipient care.All together, the work group issued 112 statements. There were 51 (45%) recommendations graded '1', 18 (16%) were graded '2' and 43 (38%) statements were not graded. There were 0 (0%) recommendations graded '1A', 15 (13%) were '1B', 19 (17%) '1C' and 17 (15%) '1D'. None (0%) were graded '2A', 1 (0.9%) was '2B', 8 (7%) were '2C' and 9 (8%) '2D'. Limitations of the evidence, especially the lack of definitive clinical outcome trials, are discussed and suggestions are provided for future research.We present here the complete recommendations about the

  14. Delayed Gastric Emptying after Living Donor Hepatectomy for Liver Transplantation

    Hanjay Wang


    Full Text Available Delayed gastric emptying is a significant postoperative complication of living donor hepatectomy for liver transplantation and may require endoscopic or surgical intervention in severe cases. Although the mechanism of posthepatectomy delayed gastric emptying remains unknown, vagal nerve injury during intraoperative dissection and adhesion formation postoperatively between the stomach and cut liver surface are possible explanations. Here, we present the first reported case of delayed gastric emptying following fully laparoscopic hepatectomy for living donor liver transplantation. Additionally, we also present a case in which symptoms developed after open right hepatectomy, but for which dissection for left hepatectomy was first performed. Through our experience and these two specific cases, we favor a neurovascular etiology for delayed gastric emptying after hepatectomy.

  16. Crosstalk between complement and Toll-like receptor activation in relation to donor brain death and renal ischemia-reperfusion injury.

    Damman, Jeffrey; Daha, Mohamed R; van Son, Willem J; Leuvenink, Henri G; Ploeg, Rutger J; Seelen, Marc A


    Two central pathways of innate immunity, complement and Toll-like receptors (TLRs), play an important role in the pathogenesis of renal injury inherent to kidney transplantation. Recent findings indicate close crosstalk between complement and TLR signaling pathways. It is suggested that mitogen activated protein kinases (MAPKs) might be the key molecules linking both the complement and TLR pathways together. Complement and TLRs are important mediators of renal ischemia-reperfusion injury (IRI). Besides IRI, complement C3 can also be upregulated and activated in the kidney before transplantation as a direct result of brain death (BD) in the donor. This local upregulation and activation of complement in the donor kidney has been proven to be detrimental for renal allograft outcome. Also TLR4 and several of its major ligands are upregulated by donor BD compared to living donors. Important and in line with the observations above, kidney transplant recipients have a benefit when receiving a kidney from a TLR4 Asp299Gly/Thr399Ile genotypic donor. The role of complement and TLRs and crosstalk between these two innate immune systems in relation to renal injury during donor BD and ischemia-reperfusion are focus of this review. Future strategies to target complement and TLR activation in kidney transplantation are considered.

  17. Prevalence and association of post-renal transplant anemia

    Hesham Elsayed


    Full Text Available In some renal allograft recipients, anemia persists or develops following transplantation. Anemia is associated with pre-operative blood loss and allograft dysfunction, including delayed graft function, acute rejection and chronic allograft dysfunction. To study the prevalence and association of post-renal transplant anemia, we studied 200 renal transplant recipients; 131 (65.5% patients were males and 69 (34.5% patients were females, and age ranged from 17 to 67 years, with a mean of 37.7 ± 10.8 years. All patients were receiving cyclosporine, prednisolone and mycophenolate mofetil (MMF. Complete blood count was done at two times: three and six months post-renal transplant. There were 74% anemic patients three months after renal transplantation and 45% anemic patients six months after renal transplantation. High creatinine value, female gender, delayed graft function, episodes of acute rejection, perioperative blood loss and infections were the only significant independent risk factors for prevalence of anemia post-renal transplant. In our study, we did not find an association between MMF and cyclosporine nor angiotensin-converting enzyme inhibitors (ACEIs or angiotensin receptors blocker (ARBs with anemia. This study demonstrates that anemia is a common complication during the first six months after kidney transplantation, with several risk factors precipitating this complication.

  19. ِAnalysis of donor motivations in living donor liver transplantation

    Hesham eAbdeldayem


    Full Text Available Objectives: The introduction of the living donor liver transplantation (LDLT in Egypt as in elsewhere, has raised important psychological conflicts and ethical questions. The objective of this study was to get better understanding of the potential donors’ motives towards LDLT.Methods:This study was conducted on consecutive 193 living –liver donors who underwent partial hepatectomy as donors for LDLT during the period between April 2003 and January 2013, at the National Liver Institute Menoufeyia University, Egypt. Potential donors were thoroughly evaluated preoperatively through a screening questionnaire and interviews as regard their demographic data, relationship to the potential recipient and motives towards proceeding to surgery. They were assured that the information shared between them and the transplant centre is confidential. Results.The donors’ mean age was 25.53± 6.39 years with a range of 18-45 years. Males represented 64.7 % and females were 35.3%. The most common donors (32.1%, n_62, were sons and daughters to their parents (sons: n_43, daughters: n_19 while parents to their offsprings represent 15% (mothers: n_21, fathers: n_8. Brothers and sisters represent 16.5 % (brothers: n_22, sisters: n_10. Nephews & nieces giving their uncles or aunts were 14%. The number of wives donating to their husbands was 11 (5.7%. Interestingly, there was no single husband who donated his wife. Among the remaining donors, there were 11 cousins & one uncle. Unrelated donors were 20 (10.4%. Several factors seemed to contribute to motivation for donation: the seriousness of the potential recipient condition, the relationship and personal history of the donor to the potential recipient, the religious beliefs, the trust in the health care system, and family dynamics and obligations.Conclusions. Absolute absence of coercion on the living-liver donor’s motives may not be realistic because of the serious condition of the potential recipient. It is

  20. New options for the management of hyperparathyroidism after renal transplantation.

    Douthat, Walter Guillermo; Chiurchiu, Carlos Raul; Massari, Pablo Ulises


    The persistence and severity of hyperparathyroidism (HPT) post-renal transplantation is relatively frequent and primarily associated with the timing and its magnitude in the pre-transplant period and with the presence of parathyroid adenomas. HPT after renal transplantation is clinically manifested with hypercalcemia, hypophosphatemia, bone pain, fractures, and in more serious cases with cardiovascular calcifications that affect the survival. The primary clinical objective for patients with secondary HPT after renal transplantation is to obtain a level of parathyroid hormone (PTH) adequate to the renal transplanted function and to normalize levels of calcium, phosphorus and vitamin D. In many cases during this period, the development of hypercalcemia and/or hypophosphatemia makes it necessary to take different therapeutic measures. The use of vitamin D or its analogues has been extrapolated from the management of pre-transplant HPT obtaining variable outcomes, although its use is limited by its capacity to produce hypercalcemia. Calcimimetics are drugs that have proven be effective in reducing PTH levels in patients with HPT on dialysis and has been effective in reducing up to 50% PTH levels in moderate to severe HPT in post-renal transplantation.When HPT persists after renal transplantation and does not respond to medical treatment, invasive management by percutaneous ethanol injection therapy of parathyroid glands or parathyroidectomy should be considered. The emergence of new methods for the management of HPT expands the availability of therapeutic tools for transplant patients.

  3. Clinical role of the renal transplant biopsy

    Williams, Winfred W.; Taheri, Diana; Tolkoff-Rubin, Nina; Colvin, Robert B.


    Percutaneous needle core biopsy is the definitive procedure by which essential diagnostic and prognostic information on acute and chronic renal allograft dysfunction is obtained. The diagnostic value of the information so obtained has endured for over three decades and has proven crucially important in shaping strategies for therapeutic intervention. This Review provides a broad outline of the utility of performing kidney graft biopsies after transplantation, highlighting the relevance of biopsy findings in the immediate and early post-transplant period (from days to weeks after implantation), the first post-transplant year, and the late period (beyond the first year). We focus on how biopsy findings change over time, and the wide variety of pathological features that characterize the major clinical diagnoses facing the clinician. This article also includes a discussion of acute cellular and humoral rejection, the toxic effects of calcineurin inhibitors, and the widely varying etiologies and characteristics of chronic lesions. Emerging technologies based on gene expression analyses and proteomics, the in situ detection of functionally relevant molecules, and new bioinformatic approaches that hold the promise of improving diagnostic precision and developing new, refined molecular pathways for therapeutic intervention are also presented.

  4. Economic analysis of basiliximab in renal transplantation.

    Keown, P A; Balshaw, R; Krueger, H; Baladi, J F


    Basiliximab is a chimeric monoclonal directed against the alpha-chain of the interleukin-2 receptor. International studies have shown that it is highly effective in preventing acute rejection in patients receiving Neoral, and causes no measurable incremental toxicity, but its economic value remains unknown. This study employed an economic model to examine the potential economic benefit of basiliximab. Parameter estimates were derived from a randomized, prospective, double-blind study conducted in 21 renal transplant centers in seven countries in which 380 adult primary allograft recipients were randomized within center to receive basiliximab (20 mg i.v.) on days 0 and 4 or placebo in addition to dual immunosuppression with Neoral and steroids. Key clinical events included primary hospitalization, immunosuppressive drug use, patient and graft survival, graft rejection, treatment of rejection, dialysis, and repeat hospitalization. Health resources were valued via a comprehensive electronic cost dictionary, based upon a detailed economic evaluation of renal transplantation in Canada. Medication costs were calculated from hospital pharmacy acquisition costs; basiliximab was assessed a zero cost. The average estimated cost per patient for the first year after transplant was $55,393 (Canadian dollars) for placebo and $50,839 for basiliximab, rising to $141,690 and $130,592, respectively, after 5 years. A principal component of the cost in both groups was accrued during the initial transplant hospitalization ($14,663 for standard therapy and $14,099 for basiliximab). An additional $15,852 and $14,130 was attributable to continued care, graft loss, and dialysis in the two groups, whereas follow-up hospitalization consumed an additional $15,538 for placebo and $13,916 for basiliximab. The mean incremental cost of dialysis was $5,397 for placebo compared with $3,821 for basiliximab, whereas incremental costs of graft loss were $2,548 compared with $2,295 in the two treatment

    AIM: To investigate the health related quality of life (HRQoL) and psychological outcome of donors after living donor liver transplantation. METHODS: Participants were 92 consecutive liver transplant donors who underwent hepatectomy without middle hepatic vein at West China Hospital of Sichuan University between January 2007 and September 2010. HRQoL was measured using the Chinese version of the Medical Outcomes Study Short Form-36 (SF-36), and psychological symptoms were measured using the Symptom Checklist-90-Revised (SCL-90-R). Data collected from donors were compared to previously published data from the general population. Clinical and demographic data were collected from medical records and questionnaires. RESULTS: The general health score of the SF-36 was significantly lower in females (59.78 ± 12.25) than in males (75.83 ± 22.09). Donors more than 40 years old scored higher in social functioning (85.71 ± 14.59) and mental health (82.61 ± 20.00) than those younger than 40 (75.00 ± 12.13, 68.89 ± 12.98; social functioning and mental health, respectively). Donors who had surgery more than two years prior to the study scored highest in physical functioning (P = 0.001) and bodily pain (P = 0.042) while those less than one year from surgery scored lowest. The health of the liver recipient significantly influenced the general health (P = 0.042), social functioning (P = 0.010), and roleemotional (P = 0.028) of donors. Donors with full-time employment scored highest in role-physical (P = 0.005), vitality (P = 0.001), social functioning (P = 0.016), mental health (P < 0.001), the physical component summary scale (P < 0.001), and the mental component summary scale (MCS) (P < 0.001). Psychological measures indicated that donors were healthier than the general population in obsessive-compulsive behavior, interpersonal sensitivity, phobic anxiety, and paranoid ideation. The MCS of the SF-36 was significantly correlated with most symptom scores of the SCL-90-R

  7. Improved Outcome of Alternative Donor Transplantations in Patients with Myelofibrosis: From Unrelated to Haploidentical Family Donors.

    Bregante, Stefania; Dominietto, Alida; Ghiso, Anna; Raiola, Anna Maria; Gualandi, Francesca; Varaldo, Riccardo; Di Grazia, Carmen; Lamparelli, Teresa; Luchetti, Silvia; Geroldi, Simona; Casarino, Lucia; Pozzi, Sarah; Tedone, Elisabetta; Van Lint, Maria Teresa; Galaverna, Federica; Barosi, Giovanni; Bacigalupo, Andrea


    This is a retrospective analysis of 95 patients with myelofibrosis who were allografted between 2001 and 2014. The aims of the study were to assess whether the outcome of alternative donor grafts has improved with time and how this compares with the outcome of identical sibling grafts. Patients were studied in 2 time intervals: 2000 to 2010 (n = 58) and 2011 to 2014 (n = 37). The Dynamic International Prognostic Scoring System score was comparable in the 2 time periods, but differences in the most recent group included older age (58 versus 53 years, P = .004), more family haploidentical donors (54% versus 5%, P < .0001), and the introduction of the thiotepa-fludarabine-busulfan conditioning regimen (70% of patients versus 2%, P < .0001). Acute and chronic graft-versus-host disease were comparable in the 2 time periods. The 3-year transplantation-related mortality (TRM) in the 2011 to 2014 period versus the 2000 to 2010 period is 16% versus 32% (P = .10), the relapse rate 16% versus 40% (P = .06), and actuarial survival 70% versus 39% (P = .08). Improved survival was most pronounced in alternative donor grafts (69% versus 21%, P = .02), compared with matched sibling grafts (72% versus 45%, P = .40). In conclusion, the outcome of allografts in patients with myelofibrosis has improved in recent years because of a reduction of both TRM and relapse. Improvement is most significant in alternative donor transplantations, with modifications in donor type and conditioning regimen.

    To evaluate the living donor selection, donor hepatectomy technique, and surgical complication in living donor liver transplantation. From June 2007 to July 2008, 74 consecutive cases living donor hepatectomy were performed by the same surgical team. Seventy-four donors (64 males and 10 females) with a mean age of 29.2 years old passed the donor liver assessment and evaluation program successfully. The hepatectomy procedure types contained right liver resection (n = 72), of which 27 cases harvested the middle hepatic vein and 45 cases not, left liver resection contain middle hepatic vein (n = 1) and left lateral resection (n = 1). Of all the donors, operation time was (6.5 +/- 6.2) hours, the mean blood loss was 300 ml (100 - 500 ml) and didn't accept foreign blood transfusion. The maximum alanine aminotransferase (ALT) level was (229.5 +/- 108.6) U/L, the ALT returned to normal time was (12.7 +/- 4.8) d, the maximum total bilirubin (TB) level was (78.7 +/- 44.3) micromol/L, the TB returned to normal time was (8.8 +/- 2.7) d, and the mean hospital stay time was 14 days (7 - 28 d). The complications included bile leak (n = 1), cut surface hemorrhage (n = 1) and anaphylactoid purpura (n = 1). All the donors returned to normal work and life finally. Precisely evaluating donor blood vascular and biliary anatomy before operation, keeping the blood vascular and bile duct integrity during operation and monitoring complication to solve it immediately after operation is crucial to ensure donor safety and recovering successfully.

    BACKGROUND:The safety of donors in living donor liver transplantation (LDLT) should be the primary consideration. The aim of this study was to report our experience in increasing the safety of donors in LDLTs using right lobe grafts. METHODS:We retrospectively studied 37 living donors of right lobe grafts from January 2002 to March 2006. The measures for increasing the safety of donors in LDLT included carefully selected donors, preoperative evaluation by ultrasonography, angiography and computed tomography; and necessary intraoperative cholangiography and ultrasonography. Right lobe grafts were obtained using an ultrasonic dissector without inlfow vascular occlusion on the right side of the middle hepatic vein. The standard liver volume and the ratio of left lobe volume to standard liver volume were calculated. RESULTS:There was no donor mortality in our group. Postoperative complications only included bile leakage (1 donor), biliary stricture (1) and portal vein thrombosis (1). All donors recovered well and resumed their previous occupations. In recipients, complications included acute rejection (2 patients), hepatic artery thrombosis (1), bile leakage (1), intestinal bleeding (1), left subphrenic abscess (1) and pulmonary infection (1). The mortality rate of recipients was 5.4% (2/37); one recipient with pulmonary infection died from multiple organ failure and another from occurrence of primary disease. CONCLUSIONS:The ifrst consideration in adult-to-adult LDLT is the safety of donors. The donation of a right lobe graft is safe for adults if the remnant hepatic vasculature and bile duct are ensured, and the volume of the remnant liver exceeds 35% of the total liver volume.

    BACKGROUND: The discrepancy between available livers and requests for transplantation has forced many centers to use marginal donors in order to expand the donor pool. Many previous studies have demonstrated controversial results of the application of steatotic liver grafts. The aim of the present study was to summarize our experience and evaluate the value of steatotic liver grafts. METHODS: The clinical and follow-up data of 24 adult patients receiving moderately steatotic liver grafts (30%-60%) from May 2003 to June 2005 (group 1) were analyzed. After matching for age, gender, model for end-stage liver diseases score and cold ischemia time, another 24 patients receiving liver grafts with steatosis less than 30%were chosen as the control group (group 2). The patient and graft outcomes were compared between the two groups. RESULTS: No difference of liver and kidney functions in the ifrst post-transplant week was found between the two groups (P>0.05). Neither the incidence of early allograft dysfunction and acute kidney injury nor the patient survival rates (3 months, 6 months and 1 year) showed differences between groups 1 and 2 (P>0.05). CONCLUSION: Moderately steatotic liver grafts provide adequate function in the ifrst phase after transplantation and can be used for transplantation.

  11. [Percutaneous Nephrolithotripsy for Renal Transplant Lithiasis: A Case Report].

    Oida, Takeshi; Kanemitsu, Toshiyuki; Hayashi, Tetsuya; Fujimoto, Nobumasa; Koide, Takuo


    A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used. Although considered to be accompanied with risks of bleeding, bowel injury, and renal dysfunction, PNL is effective for urinary lithiasis after renal transplantation. TUL is less invasive, but access may be difficult when the ureter has an unusual course or ureteral stricture exists, as in our patient.

  12. Current status of adult-to-adult living donor liver transplantation: surgical techniques and innovations

    YAN Lü-nan; WU Hong; CHEN Zhe-yu; LIN Yi-xin


    @@ In response to critical organ shortage, transplant surgeons have utilized living donors in an attempt to decrease the mortality rate associated with waiting on the liver transplant list. Although the surgical techniques were first utilized clinically 15 years ago, the application of living donor liver transplantation (LDLT) has been somewhat limited by the steep learning curve associated with developing a program.

    李秋荣; 拱玉华; 庞宝柱; 周建萍; 郜青; 赵黎明


    @@Background:Now renal transplantation is extensively used and recetpted in the clinic for treating chronic renal failure.Nutrition support and diet treatment are necessary for postoperative rehabilitation of patients underwent renal transplantation.Rigid nutrition treatment could prevent and treatment postoperative diabetes mellitus,hypertension and hyperlipemia.Diet control was also necessary for patients receiving immunodepressant.Standards and protocol for diet treatment are unavailable now.The incidence of acute rejection and allograft failure during the first year posttransplantation has been greatly reduced by advances in operative techniques, immunosuppressive agents and our understanding of their toxicities, donor selection and preservation, and donor and patient management. However, life-long immunosuppression is required to prevent the development of chronic rejection. Thus, either chronic rejection or the adverse side effects of chronic immunosuppression limit long-term survival. There is increasing incidence that posttransplant lipoprotein abnormalities may contribute to the development of cardiovascular disease (CVD). CVD is one of the most common causes of morbidity and mortality following renal transplantation. In addition, there is some indirect evidence that posttransplant lipoprotein abnormalities may influence the progression of chronic transplant nephropathy. While there are no intervention trials examining whether antilipemic therapy is beneficial in the prevention of CVD in renal transplant patients, it is reasonable to assume that the benefits of treating hyperlipidemia in renal transplant recipients may be comparable to those found in the general population. Objective:Protocol for diet treatment was determined for patients underwent renal transplantation to reduce renal load,promote recovery of renal function,and decreased the incidence of complications.

    Despite the objections to transplant tourism raised by the transplant community, many patients continue travel to other countries to receive commercial transplants. To evaluate some long-term complications, we reviewed medical records of 215 Taiwanese patients (touring group) who received commercial cadaveric renal transplants in China and compared them with those of 321 transplant recipients receiving domestic cadaveric renal transplants (domestic group) over the same 20-year period. Ten years after transplant, the graft and patient survival rates of the touring group were 55 and 81.5%, respectively, compared with 60 and 89.3%, respectively, of the domestic group. The difference between the two groups was not statistically significant. The 10-year cumulative cancer incidence of the touring group (21.5%) was significantly higher than that of the domestic group (6.8%). Univariate and multivariate stepwise regression analyses (excluding time on immunosuppression, an uncontrollable factor) indicated that transplant tourism was associated with significantly higher cancer incidence. Older age at transplantation was associated with a significantly increased cancer risk; however, the risk of de novo malignancy significantly decreased with longer graft survival. Thus, renal transplant tourism may be associated with a higher risk of post-transplant malignancy, especially in patients of older age at transplantation. © 2011 International Society of Nephrology

    AIM To systematically review reports on deceased-donor-lobar lung transplantation (ddLLTx) and uniformly describe size matching using the donor-to-recipient predicted-total lung-capacity (pTLC) ratio. METHODS We set out to systematically review reports on ddLLTx and uniformly describe size matching using the donor-to-recipient pTLC ratio and to summarize reported one-year survival data of ddLLTx and conventional-LTx. We searched in PubMed, CINAHL via EBSCO, Cochrane Database of Systematic Reviews via Wiley (CDSR), Database of Abstracts of Reviews of Effects via Wiley (DARE), Cochrane Central Register of Controlled Trials via Wiley (CENTRAL), Scopus (which includes EMBASE abstracts), and Web of Science for original reports on ddLLTx. RESULTS Nine observational cohort studies reporting on 301 ddLLTx met our inclusion criteria for systematic review of size matching, and eight for describing one-year-survival. The ddLLTx-group was often characterized by high acuity; however there was heterogeneity in transplant indications and pre-operative characteristics between studies. Data to calculate the pTLC ratio was available for 242 ddLLTx (80%). The mean pTLCratio before lobar resection was 1.25 ± 0.3 and the transplanted pTLCratio after lobar resection was 0.76 ± 0.2. One-year survival in the ddLLTx-group ranged from 50%-100%, compared to 72%-88% in the conventional-LTx group. In the largest study ddLLTx (n = 138) was associated with a lower one-year-survival compared to conventional-LTx (n = 539) (65.1% vs 84.1%, P < 0.001). CONCLUSION Further investigations of optimal donor-to-recipient size matching parameters for ddLLTx could improve outcomes of this important surgical option. PMID:28280698

  17. Early changes in scores of chronic damage on transplant kidney protocol biopsies reflect donor characteristics, but not future graft function

    The amount of irreversible injury on renal allograft biopsy predicts function, but little is known about the early evolution of this damage. In a single-center cohort, we examined the relationship between donor-, recipient-, and transplantation-associated factors and change in a morphometric index of chronic damage (ICD) between protocol biopsies performed at implantation and at 2-3 months. We then investigated whether early delta ICD predicted subsequent biochemical outcomes. We found little...

  19. Report From the American Society of Transplantation Conference on Donor Heart Selection in Adult Cardiac Transplantation in the United States.

    Kobashigawa, J; Khush, K; Colvin, M; Acker, M; Van Bakel, A; Eisen, H; Naka, Y; Patel, J; Baran, D A; Daun, T; Luu, M; Olymbios, M; Rogers, J; Jeevanandam, V; Esmailian, F; Pagani, F D; Lima, B; Stehlik, J


    Cardiac transplantation remains the only definitive treatment for end-stage heart failure. Transplantation rates are limited by a shortage of donor hearts. This shortage is magnified because many hearts are discarded because of strict selection criteria and concern for regulatory reprimand for less-than-optimal posttransplant outcomes. There is no standardized approach to donor selection despite proposals to liberalize acceptance criteria. A donor heart selection conference was organized to facilitate discussion and generate ideas for future research. The event was attended by 66 participants from 41 centers with considerable experience in cardiac donor selection. There were state-of-the-art presentations on donor selection, with subsequent breakout sessions on standardizing the process and increasing utilization of donor hearts. Participants debated misconceptions and established agreement on donor and recipient risk factors for donor selection and identified the components necessary for a future donor risk score. Ideas for future initiatives include modification of regulatory practices to consider extended criteria donors when evaluating outcomes and prospective studies aimed at identifying the factors leading to nonacceptance of available donor hearts. With agreement on the most important donor and recipient risk factors, it is anticipated that a consistent approach to donor selection will improve rates of heart transplantation. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  2. Towards non-invasive diagnostic techniques for early detection of acute renal transplant rejection: A review

    Elizabeth Hollis


    Full Text Available The kidney is a very important complicated filtering organ of the body. When the kidney reaches stage 5 chronic kidney disease, end stage renal failure, the preeminent therapy is renal transplantation. Although it is the best form of treatment, lack of kidney donors is still challenging. Therefore, all efforts should be employed to prolong the survival rate of the transplanted kidney. However, graft dysfunction (e.g., acute rejection is one of the serious barriers to long term kidney transplant survival. Currently, graft dysfunction’s gold standard of diagnosis is renal biopsy. Although renal biopsy is helpful, it is not preferred due to its invasive nature, high morbidity rates, and expensiveness. Therefore, noninvasive imaging techniques have become the subject of extensive research and interest, giving a strong promise to replace, or at least to decrease, biopsy usage in diagnosing graft dysfunction. This survey will discuss not only the current diagnosis and treatment of graft dysfunction but also the state-of-the-art imaging techniques in detecting acute renal transplant rejection.

  3. Diaphragmatic hernia after right donor and hepatectomy:a rare donor complication of partial hepatectomy for transplantation

    Alan M. Hawxby; David P. Mason; Andrew S. Klein


    BACKGROUND: Because of the critical worldwide shortage of cadaveric organ donors, transplant professionals have increasingly turned to living donors. Partial hepatectomy for adult living donor liver transplantation has been performed since the late 1990s. Most often, the complications of living donor hepatectomy have been related to the biliary tract, speciifcally biliary leaks. METHODS: A 54-year-old man underwent donor right hepatectomy for living donor liver transplantation. Three years after liver donation he presented with upper abdominal pain and fullness. Radiographic workup revealed a diaphragmatic hernia of the right hemithorax. RESULTS: After thoracoscopic evaluation of the right hemithorax, diaphragmatic hernia was repaired. Currently the patient remains well several months after the repair with complete resolution of abdominal pain, normal chest X-ray examination demonstrating no recurrence of diaphragmatic hernia, and normal liver functions tests. CONCLUSIONS: Multiple complications of living donor liver transplantation have been described the transplant literature. Diaphragmatic hernia is a formerly-undescribed complication of right donor hepatectomy for transplantation.

    Return to work is an objective parameter used worldwide to evaluate the success of organ transplantation and is especially feasible after renal transplantation. This study sought to describe the frequency of return to work after renal transplantation and related characteristics. Retrospective cohort of 511 isolated kidney transplant recipients was recruited from a Brazilian referral center from January 2005 to December 2009; all were matched to the public social security database to determine inclusion and benefit awards, as well as the rate of resumption of contributions to the public social security system, a surrogate marker of work rehabilitation. Characteristics associated with work return were analyzed. No social security records were found for 28 subjects. The remaining 483 subjects had a mean age of 45±13 years; 62% were male; 401 (83%) received some public social security benefit; 298 were paying dues and could, therefore, receive temporary or permanent disability benefits. Of these, 78 subjects made social security payments after transplantation, resulting in a work return rate of 26% (95% confidence interval, 21-32). Younger age, living donor graft, and chronic glomerulonephritis were significantly associated with return to work. In Brazil, most renal transplant recipients are on social security benefits, but only a small proportion return to work after surgery. Clinical characteristics may help define work resumption trends.

  7. FSGS Recurrence in Adults after Renal Transplantation

    Michael Rudnicki


    Full Text Available Recurrence of focal segmental glomerulosclerosis (FSGS in the allograft occurs in 30–50% of patients, and it is associated with poor renal allograft survival. Major risk factors for recurrence are younger age at diagnosis, rapid progression to end-stage renal disease, white race, and the loss of previous allografts due to recurrence. Recent data support the hypothesis that circulating permeability factors play a crucial role in podocyte injury and progression of FSGS. Due to lack of controlled trials, the management of recurrent FSGS is inconsistent and highly empirical. Prophylactic and perioperative treatment with plasmapheresis and high-dose (intravenous cyclosporine represent the main cornerstones of immunosuppressive therapy. In recent years, therapy with rituximab has shown promising results. Despite evidence of activation of the renin-angiotensin system (RAS in recurrent FSGS and its association with progression, only limited data exist on the renoprotective role of RAS blockade in this setting. Further well designed studies are needed on pathogenesis risk factors and therapeutical options in FSGS and its recurrence after transplantation.

  9. First Canadian Case Report of Kidney Transplantation From an HIV-Positive Donor to an HIV-Positive Recipient

    Ambaraghassi, Georges; Cardinal, Héloïse; Corsilli, Daniel; Fortin, Claude; Fortin, Marie-Chantal; Martel-Laferrière, Valérie; Malaise, Jacques; Pâquet, Michel R.; Rouleau, Danielle


    Rationale: Kidney transplantation has become standard of care for carefully selected patients living with human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) in the highly active antiretroviral therapy (HAART) era. American and European prospective cohort studies have reported similar patient and graft survival compared with HIV-negative kidney transplant recipients. Despite an increased rate of acute rejection, partially due to drug interactions, HIV immunovirologic parameter generally remains under control during immunosuppression. A few cases of kidney transplantation between HIV-infected patients were done in South Africa and showed favorable results. No cases of kidney transplantation from an HIV-positive donor in Canada have previously been reported. Presenting concerns of the patient: A 60-year-old Canadian man with HIV infection presented in 2007 with symptoms compatible with acute renal failure secondary to IgA nephropathy. Chronic kidney disease resulted after the acute episode. Diagnoses: Hemodialysis was started in 2012. The patient was referred for a kidney transplantation evaluation. Interventions: The patient underwent kidney transplantation from an HIV-positive donor in January 2016. The recipient’s antiretroviral regimen consisted of abacavir, lamivudine, and dolutegravir. No drug interactions have been reported between these antiretrovirals and the maintenance immunosuppressive regimen used. Outcomes: The outcome at 7 months post transplantation was excellent, with good graft function and adequate control of HIV replication, in the absence of opportunistic infections at a time when immunosuppression is at its highest intensity. No acute rejection was reported. An episode of bacteremic graft pyelonephritis due to Enterococcus faecalis was successfully treated after transplantation. Novel finding: With careful selection of patient, kidney transplantation between HIV-infected patients is a viable option. The use of antiretroviral

  10. Autologous stem cell transplantation versus alternative allogeneic donor transplants in adult acute leukemias.

    Claude Gorin, Norbert


    The availability of alternative sources of stem cells including most recently T-replete haploidentical marrow or peripheral blood, and the increasing use of reduced-intensity conditioning (RIC), renders feasible an allogeneic transplant to almost all patients with acute leukemia up to 70 years of age. Autologous stem cell transplantation (ASCT) for consolidation of complete remission (CR), however, offers in some circumstances an alternative option. Although associated with a higher relapse rate, autologous transplant benefits from a lower non-relapse mortality, the absence of graft-versus-host disease (GVHD), and a better quality of life for long-term survivors. The recent use of intravenous busulfan (IVBU) with high-dose melphalan, better monitoring of minimal residual disease (MRD), and maintenance therapy post autografting bring new interest. Few retrospective studies compared the outcome following alternative donor versus autologous transplants for remission consolidation. Genoidentical and phenoidentical allogeneic stem cell transplantations are undisputed gold standards, but there are no data showing the superiority of alternative allogeneic donor over autologous transplantation, at the time of undetectable MRD, in patients with good- and intermediate-1 risk acute myelocytic leukemia (AML) in first complete remission (CR1), acute promyelocytic leukemia in second complete remission (CR2), and Philadelphia chromosome-positive (Ph(+)) acute lymphocytic leukemia (ALL).

  11. Intravenous renal cell transplantation with SAA1-positive cells prevents the progression of chronic renal failure in rats with ischemic-diabetic nephropathy.

    Kelly, Katherine J; Zhang, Jizhong; Han, Ling; Wang, Mingsheng; Zhang, Shaobo; Dominguez, Jesus H


    Diabetic nephropathy, the most common cause of progressive chronic renal failure and end-stage renal disease, has now reached global proportions. The only means to rescue diabetic patients on dialysis is renal transplantation, a very effective therapy but severely limited by the availability of donor kidneys. Hence, we tested the role of intravenous renal cell transplantation (IRCT) on obese/diabetic Zucker/SHHF F1 hybrid (ZS) female rats with severe ischemic and diabetic nephropathy. Renal ischemia was produced by bilateral renal clamping of the renal arteries at 10 wk of age, and IRCT with genetically modified normal ZS male tubular cells was given intravenously at 15 and 20 wk of age. Rats were euthanized at 34 wk of age. IRCT with cells expressing serum amyloid A had strong and long-lasting beneficial effects on renal function and structure, including tubules and glomeruli. However, donor cells were found engrafted only in renal tubules 14 wk after the second infusion. The results indicate that IRCT with serum amyloid A-positive cells is effective in preventing the progression of chronic kidney disease in rats with diabetic and ischemic nephropathy.

    Deceased donor (DDLT) and living donor (LDLT) liver transplant (LT) is in vogue in several centers in India. Most centers are resorting to LDLT as a preferred surgery due to shortage of deceased donor liver. The risk of infection and its effect on survival in both groups of recipients from the Indian subcontinent are not known. The study was conducted to compare the bacterial infection rates among LDLT and DDLT recipients and their impact on survival at a tertiary referral center. Retrospective data on 67 LT recipients were reviewed. Data on pre-, per-, and postoperative bacterial infection rates and the common isolates were obtained. Thirty-five patients had LDLT and 32 had DDLT. The prevalence of pre-operative bacterial infection and the isolates was similar in both groups. The perioperative bacterial infection rates were significantly higher in DDLT recipients (P urinary tract followed by bloodstream infection. The common bacterial isolates in either transplant were Klebsiella followed by Escherichia coli, Pseudomonas spp. and nonfermenting gram-negative bacteria. Six patients (four LDLT; two DDLT) were treated for tuberculosis. Among the risk factors, cold ischemic time, and duration of stay in the intensive care unit was significantly higher for DDLT (p < 0.01). The death rates were not significantly different in the two groups. However, the odds for death were significantly high at 26.8 (p < 0.05) for postoperative bacterial infection and 1.8 (p < 0.001) for past alcohol. Liver transplant recipients are at high-risk for bacterial infection irrespective of type of transplant, more so in DDLT.

  17. Specificities of transplantation of kidneys procured from donors with situs inversus totalis: A case report and review of the literature

    Petrović Milica


    Full Text Available Introduction. Situs inversus totalis (SIT represents a total vertical transposition of the thoracic and abdominal organs which are arranged in a mirror image reversal of the normal positioning 1. We presented a successful pre-dialysis kidney transplantation from a living sibling donor with SIT and the longest donor follow-up period, along with analysis of the reviewed literature. Case report. The pair for pre-dialysis kidney transplantation included a 68-year-old mother and 34-year-old daughter at low immunological risk. Comorbidities evidenced in kidney donors with previously diagnosed SIT, included moderate arterial hypertension and borderline blood glucose level. Explantation of the left donor kidney and its placement into the right iliac fossa of the recipient were performed in the course of the surgical procedure. A month after nephrectomy, second degree renal failure was noticed in the donor. A 20-month follow-up of the donor’s kidney and graft in the recipient proved that their functions were excellent. Conclusion. In donors with previously diagnosed SIT the multidisciplinary approach, preoperative evaluation of the patient and detection of possible vascular anomalies are required to provide maximum safety for the donor.

    Both humoral and cellular immune responses are involved in renal allograft rejection. Interleukin (IL)-6 is a regulatory cytokine for both B and Foxp3 (forkhead box P3)-expressing regulatory T (Treg) cells. This study was designed to investigate the impact of donor IL-6 production on renal allograft survival. Donor kidneys from IL-6 knockout (KO) vs. wild-type (WT) C57BL/6 mice (H-2(b)) were orthotopically transplanted to nephrotomized BALB/c mice (H-2(d)). Alloantibodies and Treg cells were examined by fluorescence-activated cell sorting analysis. Graft survival was determined by the time to graft failure. Here, we showed that a deficiency in IL-6 expression in donor kidneys significantly prolonged renal allograft survival compared with WT controls. IL-6 protein was upregulated in renal tubules and endothelium of renal allografts following rejection, which correlated with an increase in serum IL-6 compared with that in those receiving KO grafts or naive controls. The absence of graft-producing IL-6 or lower levels of serum IL-6 in the recipients receiving IL-6 KO allografts was associated with decreased circulating anti-graft alloantibodies and increased the percentage of intragraft CD4(+)CD25(+)Foxp3(+) Treg cells compared with those with WT allografts. In conclusion, the lack of graft-producing IL-6 significantly prolongs renal allograft survival, which is associated with reduced alloantibody production and/or increased intragraft Treg cell population, implying that targeting donor IL-6 may effectively prevent both humoral and cellular rejection of kidney transplants.

    Aim: To investigate the changes of the spermatozoa ultrastructures before and after renal transplantation in uremic patients. Methods: The sperm of five uremic patients before and after transplantation and four healthy volunteers were collected and examined by scanning electron microscopy. Results: Abnormal spermatozoa were found in patients pre-transplantation; abnormalities included deletion of the acrosome, absence of the postacrosomal and postnuclear ring, dumbbell-like changes of the head, tail curling, and absence of the mitochondrial sheath in the midsegment. After renal transplantation, most of the spermatozoa became normal. Conclusion: There are many abnormalities with regard to the appearance and structure of the head, acrosome, mitochondria and tail of the spermatozoa in uremic patients. The majority of the spermatozoa returned to normal after renal transplantation, but a few still presented some abnormalities possibly relating to the administration of immunosuppressants.

  20. Donor Heart Utilization following Cardiopulmonary Arrest and Resuscitation: Influence of Donor Characteristics and Wait Times in Transplant Regions

    Mohammed Quader


    Full Text Available Background. Procurement of hearts from cardiopulmonary arrest and resuscitated (CPR donors for transplantation is suboptimal. We studied the influences of donor factors and regional wait times on CPR donor heart utilization. Methods. From UNOS database (1998 to 2012, we identified 44,744 heart donors, of which 4,964 (11% received CPR. Based on procurement of heart for transplantation, CPR donors were divided into hearts procured (HP and hearts not procured (HNP groups. Logistic regression analysis was used to identify predictors of heart procurement. Results. Of the 4,964 CPR donors, 1,427 (28.8% were in the HP group. Donor characteristics that favored heart procurement include younger age (25.5 ± 15 yrs versus 39 ± 18 yrs, P≤0.0001, male gender (34% versus 23%, P≤0.0001, shorter CPR duration (30 min, P≤0.0001, and head trauma (60% versus 15%. Among the 11 UNOS regions, the highest procurement was in Region 1 (37% and the lowest in Region 3 (24%. Regional transplant volumes and median waiting times did not influence heart procurement rates. Conclusions. Only 28.8% of CPR donor hearts were procured for transplantation. Factors favoring heart procurement include younger age, male gender, short CPR duration, and traumatic head injury. Heart procurement varied by region but not by transplant volumes or wait times.

    Erasmus, Michiel E.; Verschuuren, Erik A. M.; Nijkamp, Danielle M.; Vermeyden, J. Wytse; van der Bij, Wim


    Background. Despite the increasing use of extended lung donors, the shortage of lung donors remains. Usage of non-heart-beating (NHB) lung donors contributes to fight this shortage. We describe our experience in 21 consecutive adult lung transplantations using nonheparinized category III NHB donors

  2. Methylene blue treatment for resistant shock following renal transplantation.

    Hershman, Eli; Hadash, Amir; Attias, Ori; Ben-Ari, Josef


    We report a case of a 19-year-old female with a history of hyperoxaluria type 1 and renal failure. The patient presented for a second renal transplantation 17 years after her first combined liver and kidney transplantation. Postoperative shock was highly resistant to fluids and required massive pharmacologic hemodynamic support. Vasoplegic shock was the presumed diagnosis, and methylene blue was utilized as a rescue therapy, with a rapid hemodynamic response and no apparent side effects.

  3. Percutaneous coronary interventions and antiplatelet therapy in renal transplant recipients.

    Summaria, Francesco; Giannico, Maria Benedetta; Talarico, Giovanni Paolo; Patrizi, Roberto


    Cardiovascular disease is the leading cause of mortality and morbidity following renal transplantation (RT), accounting for 40-50% of all deaths. After renal transplantation, an adverse cardiovascular event occurs in nearly 40% of patients; given the dialysis vintage and the average wait time, the likelihood of receiving coronary revascularization is very high. There is a significant gap in the literature in terms of the outcomes of prophylactic coronary revascularization in renal transplantation candidates. Current guidelines on myocardial revascularization stipulate that renal transplant patients with significant coronary artery disease (CAD) should not be excluded from the potential benefit of revascularization. Compared with percutaneous coronary intervention (PCI), however, coronary artery bypass grafting is associated with higher early and 30-day mortality. About one-third of renal transplant patients with CAD have to be treated invasively and so PCI is currently the most popular mode of revascularization in these fragile and compromised patients. A newer generation drug-eluting stent (DES) should be preferred over a bare metal stent (BMS) because of its lower risk of restenosis and improved safety concerns (stent thrombosis) compared with first generation DES and BMS. Among DES, despite no significant differences being reported in terms of efficacy, the newer everolimus and zotarolimus eluting stents should be preferred given the possibility of discontinuing, if necessary, dual antiplatelet therapy before 12 months. Since there is a lack of randomized controlled trials, the current guidelines are inadequate to provide a specifically tailored antiplatelet therapeutic approach for renal transplant patients. At present, clopidogrel is the most used agent, confirming its central role in the therapeutic management of renal transplant patients undergoing PCI. While progress in malignancy-related mortality seems a more distant target, a slow but steady reduction in

  4. Living Kidney Donor Transplantation in a Resource-limited Country: The Ivory Coast Experience.

    Ackoundou-N'Guessan, C; Hoang, A D; Ben Abdallah, T; Gnionsahe, D A; Dollo, I; Ripoche, C; Coulibaly, N; Aye, D Y; N'Guessan, F Y; Diby Kouame, B; Guei, C M; Tia, M W; Amekoudji, Y; Lagou, D A


    Renal transplantation that offers a good quality of life still is not performed by the majority of countries of black Africa. We started a pilot project of renal transplantation in Ivory Coast 2 years ago. The present paper reports the preliminary results, difficulties related to the program, and perspectives regarding its expansion. Ten living related kidney transplantations have been performed over a 2-year period. Recipients and their respective donors were male. The mean age of the recipients was 42.8 years (22-57), and the mean age of the donors was 29.4 years (22-43). The mean number of mismatches was 3.2 (0-6). None was immunized. Recipients and donors were all EBV IgG positive and CMV IgG positive. All but 1 case were induced with basiliximab. The mean graft and patient survival time was 16.6 months (6-26). The mean cold ischemic time was 2.27 hours (1-3.32). The mean serum creatinine at discharge was 241.87 μmol/L (115.18-1063.2), at 6 months was 117.20 μmol/l (95.6-139.9), at 12 months was 104.55 μmol/L (62.02-132.9), and at 24 months was 104.55 μmol/L (62.02-132.9). The mean cyclosporine through level (C0) at 6 months was 137.57 ng/mL (70-366), at 12 months was 117.33 ng/mL (62-197), and at 24 months was 78 ng/mL. The mean cyclosporine 2-hour post-administration concentration levels (C2) at 6 months was 764.9 ng/mL (430-1421), at 12 months was 937.17 ng/mL (483-1292), and at 24 months was 690.66 ng/mL (488-853). Main complications were sepsis, adenovirus hemorrhagic cystitis, new-onset diabetes after transplantation, delayed graft function, polycythemia, and cytomegalovirus infection. No clinical rejection was diagnosed over the 2-year period. Patient and graft survival was 100% at a mean post-transplantation time of approximately 16.6 months. Copyright © 2015 Elsevier Inc.

  5. Calcineurin inhibitors and male fertility after renal transplantation - a review.

    Georgiou, G K; Dounousi, E; Harissis, H V


    Renal transplantation and restoration of renal function are associated with significant favourable changes regarding the reproductive capacity of male patients with previous end-stage renal disease. However, there is evidence that some of the immunosuppressive agents may impair male fertility after all. Calcineurin inhibitors (CNIs), cyclosporine A and tacrolimus (FK506), which constitute the cornerstone of immunosuppression regimen following renal transplantation, have been implicated in causing an overall decline in the fertilisation capacity of male renal transplant recipients (RTRs). In this review, data from human clinical studies are collectively presented in an effort to estimate the potential adverse effects of CNIs on the masculine reproductive organs, the hormonal axis of males, the process of spermatogenesis and generally the male RTRs capacity to fertilise. © 2015 Blackwell Verlag GmbH.

  6. Liver grafts for transplantation from donors with diabetes: an analysis of the Scientific Registry of Transplant Recipients database.

    Zheng, Jun; Xiang, Jie; Zhou, Jie; Li, Zhiwei; Hu, Zhenhua; Lo, Chung Mau; Wang, Weilin


    Patients with a history of diabetes mellitus (DM) have worse survival than those without DM after liver transplantation. However, the effect of liver grafts from DM donors on the post-transplantation survival of recipients is unclear. Using the Scientific Registry of Transplant Recipients database (2004-2008), 25,413 patients were assessed. Among them, 2,469 recipients received grafts from donors with DM. The demographics and outcome of patients were assessed. Patient survival was assessed using Kaplan-Meier methodology and Cox regression analyses. Recipients from DM donors experienced worse graft survival than recipients from non-DM donors (one-year survival: 81% versus 85%, and five-year survival: 67% versus 74%, PGraft survival was significantly lower for recipients from DM donors with DM duration >5 years (Pgraft survival (hazard ratio, 1.11; 95% confidence interval, 1.02-1.19). The effect of DM donors was more pronounced on certain underlying liver diseases of recipients. Increases in the risk of graft loss were noted among recipients from DM donors with hepatitis-C virus (HCV) infection, whereas those without HCV experienced similar outcomes compared with recipients from non-DM donors. These data suggest that recipients from DM donors experience significantly worse patient survival after liver transplantation. However, in patients without HCV infection, using DM donors was not independently associated with worse post-transplantation graft survival. Matching these DM donors to recipients without HCV may be safe.

  7. ABO-incompatible living-donor pediatric kidney transplantation in Japan

    Atsushi Aikawa


    Full Text Available The Japanese ABO-Incompatible Transplantation Committee officially collected and analyzed data on pediatric ABO-incompatible living-donor kidney transplantation in July 2012. The age of a child was defined as <16 years, and 89 children who had undergone ABO-incompatible living-donor kidney transplantation from 1989 to 2011 were entered in a registry. These data were presented as the Japanese registry of pediatric ABO-incompatible living-donor kidney transplantation at the regional meetings of the International Pediatric Transplantation Association (IPTA in Nagoya in September 2012 and in Sao Paulo in November 2012.

  8. Fatal EBV-related post-transplant lymphoproliferative disorder (LPD) after matched related donor nonmyeloablative peripheral blood progenitor cell transplant.

    Zamkoff, K W; Bergman, S; Beaty, M W; Buss, D H; Pettenati, M J; Hurd, D D


    A 39-year-old male underwent a nonmyeloablative stem cell transplant (NMAPBPCT) from his HLA-matched sister for recurrent anaplastic large cell lymphoma in CR-2, receiving fludarabine, cyclophosphamide, and rabbit antithymocyte globulin for the preparative therapy. The patient was readmitted on day+33 for persistent culture-negative fevers. He rapidly developed marked elevations of alkaline phosphatase and bilirubin. Liver biopsy showed a periportal infiltrate of large immunoblastic appearing cells. The tumor cells did not stain for CD3/CD20/CD30 and alk protein, but did stain for CD79a/LCA and CD43. In situ hybridization for Epstein-Barr virus (EBV) RNA (EBER 1) was strongly positive in the periportal infiltrating lymphocytes. Fluorescence in situ hybridization (FISH) studies revealed female (XX) cells in the tumor cells and male (XY) in the surrounding hepatic parenchymal cells. The patient developed severe lactic acidosis, oliguric renal failure and expired on day+44. Both donor and patient had positive IgG serologies for EBV VCA and EBNA pretransplant. The donor also had a positive IgM titer for EBV VCA in the pretransplant specimen. The LPD may have been related to the intense immunosuppression of the preparative therapy and the presence of recent EBV infection in the donor.

  9. Acute renal failure in liver transplant patients: Indian study.

    Naik, Pradeep; Premsagar, B; Mallikarjuna, M


    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

  10. Influence of Donors’ and Recipients’ HLA Typing on Renal Function Immediately After Kidney Transplantation

    Rostami, Zohreh; Shafighiee, Nasrollah; Baghersad, Mohammad Mahdi; Einollahi, Behzad


    Background The human leukocyte antigen (HLA) system is widely used as a strategy in the search for the etiology of renal function impairment. Objectives This study was carried out to detect the most common HLA alleles’ distribution in kidney transplant in both donors and recipients, and clarify the association between HLA alleles and renal dysfunction immediately after transplantation. Patients and Methods HLA-class I and II alleles typing by PCR-SSOP was performed on a total of 874 recipients aged 40.7 ± 13.8 (male/female: 562/279) and 874 donor aged 27.5 ± 5.3 (male/female: 683/110), between 2006 and 2009 in Baqiyatallah, hospital, Tehran, Iran. In this retrospective, cross sectional study, data were obtained from personal files. Donors aged 40.9 ± 13.6 years and male/female 390/195, while recipients had a mean age 27.5 ± 5.3 and male/female 523/83. Renal dysfunction defined as acute rejection, acute tubular necrosis and Delay graft function. Results In this study common alleles at each of the loci for the human leukocyte antigen (HLA) class I (A, B, and C) and class II (DR and DQ) were A2 (n = 186, 33.8%), Bw6 (n = 196, 47.5%), Cw4 (n = 164, 39.7%), DR52 (n = 161, 29.6%), DQ3 (n = 101, 40.1%) for donors; while A2 (n = 200, 34%), BW6 (n = 235, 38.8%), Cw6 (n = 23, 15.2%), DR511 (n = 174, 30.4%), DQ1 (n = 99, 46.3%) for recipients. We detected a total of 139 case of renal dysfunction among RTRs. By the way only cold ischemic time (P = 0.03) and severe anemia (P = 0.000) were significantly associated with renal dysfunction early post kidney transplantation. Conclusions We can predict high risk groups before kidney transplantation and try to establish a screening program for the detection of genetic susceptibility to renal function impairment. HLA typing of the donors and recipients might influence the development of new treatment strategy. PMID:24693507

  11. Pediatric Renal Transplantation in a Highly Sensitised Child—8 Years On

    Catherine Quinlan


    Full Text Available Highly sensitised children have markedly reduced chances of receiving a successful deceased donor renal transplant, increased risk of rejection, and decreased graft survival. There is limited experience with the long-term followup of children who have undergone desensitization. Following 2 failed transplants, our patient was highly sensitised. She had some immunological response to intravenous immunoglobulin (IVIg but this was not sustained. We developed a protocol involving sequential therapies with rituximab, IVIg, and plasma exchange. Immunosuppressant therapy at transplantation consisted of basiliximab, tacrolimus, mycophenolate mofetil, and steroids. At the time of transplantation, historical crossmatch was ignored. Current CDC crossmatch was negative, but T and B cell flow crossmatch was positive, due to donor-specific HLA Class I antibodies. Further plasma exchange and immunoglobulin therapy were given pre- and postoperatively. Our patient received a deceased donor-kidney-bearing HLA antigens to which she originally had antibodies, which would have precluded transplant. The graft kidney continues to function well 8 years posttransplant.

  12. Risk and outcome of pyelonephritis among renal transplant recipients.

    Graversen, Mette Elneff; Dalgaard, Lars Skov; Jensen-Fangel, Søren; Jespersen, Bente; Østergaard, Lars; Søgaard, Ole Schmeltz


    Urinary tract infection is the most common infectious disease requiring hospitalisation following renal transplantation. However, the risk and outcome of post-transplant pyelonephritis remains unclear. This population-based cohort study was conducted from 1 January 1990 to 31 December 2009. Each member of a Danish population-based, nationwide cohort of first-time renal transplant recipients was matched by age and gender with up to 19 population controls. Information on hospital discharge diagnosis, emigration, and mortality was obtained from nationwide administrative databases. Individuals were observed from the date of first renal transplantation and until graft loss, emigration, or death. Risk factors were assessed by Poisson regression. The incidence rate (IR) of first-time hospitalisation for pyelonephritis was 18.5 (95 % confidence interval [CI]: 16.4-20.9) per 1,000 person-years of follow-up (PYFU) among renal transplant recipients (N = 2,656) and 0.26 (CI: 0.21-0.31) per 1,000 PYFU among population controls (N = 49,226) yielding an incidence rate-ratio (IRR) of 72.0 (95 % CI: 57.8-89.7). Among renal transplant recipients, the risk of pyelonephritis decreased during the entire study period and was lowest in 2005-09 (IRR = 0.46, CI: 0.31-0.68). The highest risk of pyelonephritis was observed within the first six months post-transplantation (IR = 69.9 per 1,000 PYFU; CI: 56.4-86.7). Other risk factors for post-transplant pyelonephritis included female gender, high Charlson comorbidity index score, HLA-DR mismatch, cause of renal failure, and calendar period. Interestingly, we found that the combined risk of graft loss and death was 45 %, (CI: 19-77 %) higher in renal transplant recipients following post-transplant pyelonephritis compared to those who had no admission due to pyelonephritis. The risk of first-time hospitalisation for pyelonephritis among renal transplant recipients is high. Further, post-transplant pyelonephritis was

    Sreejith, P; Kuthe, S; Jha, V; Kohli, H S; Rathi, M; Gupta, K L; Sakhuja, V


    Tuberculosis is a common cause of pericarditis in the developing countries and constrictive pericarditis is a serious sequel. There are only three cases of constrictive pericarditis in kidney transplant recipients previously reported in literature. Here, we report a case of constrictive pericarditis developing in a renal transplant recipient while on antituberculous therapy for tuberculous pleural effusion.

    Kohata, Katsura; Fujiwarw, Tohru; Yamamoto, Joji; Yamada, Minami; Ishizawa, Kenichi; Satoh, Kazushige; Sekiguchi, Satoshi; Kameoka, Junichi; Satomi, Susumu; Harigae, Hideo


    A case of severe autoimmune hemolytic anemia after ABO matched living donor liver transplantation. We present here a case of severe autoimmune hemolytic anemia after ABO matched living donor liver transplantation. The patient is 56 y.o male. He received living donor liver transplantation from his ABO matched son in May 2007. In July, he was suffered from a progressive anemia, and diagnosed as autoimmune hemolytic anemia by the laboratory examinations. Intensive treatment including predonisolone, azathiopurine, rituximab, plasma exchange, was given, however, the disease was resistant to the treatment. By the administration of cyclophosphamide combined with rituximab, remission was finally achieved. To date, immune mediated hemolytic anemia after ABO matched living donor liver transplantation has not been reported, although several cases of ABO mismatched living donor liver transplantation have been reported. His severe but transient clinical course of anemia suggests that the transient emergence of donor lymphocytes may be responsible for onset of hemolytic anemia.

    A 59-year-old woman with end-stage renal disease of diabetic nephropathy who had been on maintenance hemodialisis for 4 years, underwent a living-unrelated renal transplantation 6 years ago. She was admitted to our hospital, because of a low grade fever and edema. Ultrasonography revealed the cyst with heterogeneity structure in the upper pole of the transplanted kidney. Magnetic resonance imaging showed a high-intensity cystic mass measuring 68×53 mm. As fever and laboratory data did not improve sufficiently by the treatment with antibiotics, echo-guided puncture and drainage were performed for the abnormal structure in the upper pole of the transplanted kidney. In the culture of the purulent aspirate drained from renal cyst, Escherichia coli was isolated. To our knowledge, this is the first report of infected renal cyst of the graft in a renal transplant recipient in the world.

  1. Intermediate steroid withdrawal after renal transplantation and anti-HLA antibodies (HLA-Abs) development.

    Monfá, Elena; San Segundo, David; San Millán, Juan Carlos Ruiz; Sanabria, Judith; Albines, Zoila; Rodrigo, Emilio; Romón, Iñigo; Asensio, Esther; Arias, Manuel; López-Hoyos, Marcos

    Steroid withdrawal in renal transplantation is desirable to avoid their adverse effects. However, by decreasing the immunosuppression, could lead to an increased risk for the development of HLA-Abs. Evaluate the relationship between steroid withdrawal and development of HLA-Abs in renal transplantation. We analyzed sera by Luminex from 182 kidney transplants performed from 1998 to 2011, before and two years after transplantation. All the patients had a pretransplant PRA (panel reactive of antibodies) 20%, we detected HLA-Abs pretransplant by Luminex in 11.5% of patients in both groups, of which, 66.6%, versus 53% (p 0.058), developed new specificities, with a similar percentage of donor specific antibodies (DSA) in both groups (33.33% vs 36.36%), pNS. In the subgroup without pretransplant HLA-Abs (group-I; n=115, group-II; n=45), 6.08% developed de novo HLA-Abs, being DSA 3.4% (Group-I) versus 7.69% in group II with 3.84% DSA (pNS). Steroid withdrawal at 7 months of renal transplantation does not entail a higher risk in terms of HLA-Abs development in patients without pretransplant HLA-Abs and treatment with tacrolimus and MMF, although larger studies are needed to confirm these findings.

  2. Relapsing Urinary Tract Infection Due to Rectourethral Fistula in a Renal Transplant Recipient

    Ayşegül ORUÇ KOÇ


    Full Text Available Objectives: Urinary tract infection (UTI is the most common cause of bacterial infection in renal transplant recipients. It occurs frequently in the early period because of the high-dose immunosuppressive agents and urethral catheterizations. Relapsing UTI may lead to graft dysfunction and further evaluations have to be performed for predisposing factors. We report the case of a renal transplant recipient who presented with relapsing bacterial UTI due to a rectourethral fistula. Case: A 24-year-old male patient underwent a successful renal transplantation from a living donor on May 2008. He had a history of surgical intervention for anal atresia and rectourethral fistula. He was hospitalized five times because of relapsing bacterial UTI after transplantation. We investigated the presence of an anatomical abnormality and found a rectourethral fistula. After the surgical repair of the fistula the UTI did not relapse. Conclusion: Relapsing infections are not uncommon and anatomical abnormalities can lead to relapsing UTI in transplant recipients. Further investigations must be performed regarding the factors that might contribute to the development of UTIs in the presence of relapsing UTI.

    Del Pozo, Maitane; Martí, Jordi; Guirado, Lluís; Facundo, Carme; Canal, Cristina; de la Torre, Pablo; Ballarín, José; Díaz, Joan M


    Transplant renal artery stenosis is a major complication that requires a therapeutic approach involving surgery or angioplasty. The aim of this study was to analyse the evolution of renal transplant patients with renal allograft artery stenosis treated by angioplasty and stent placement. Thirteen patients were diagnosed with transplant renal artery stenosis. Clinical suspicion was based on deterioration of renal function and/or poorly controlled hypertension with compatible Doppler ultrasound findings. The diagnosis was confirmed by arteriography, performing an angioplasty with stent placement during the same operation. A progressive improvement in renal function was observed during the first 3 months after the angioplasty, and renal function then remained stable over 2 years. In addition, blood pressure improved during the first 2 years, and as a consequence there was no need to increase the average number of anti-hypertensive drugs administered (2.5 drugs per patient). In conclusion, angioplasty with stent placement is a safe and effective procedure for the treatment of transplant renal artery stenosis.

    Until recently long-term renal toxicity has not been considered a major late complication of bone marrow transplantation (BMT). Late renal dysfunction has been described in a pediatric population status post-BMT which was attributable to the radiation in the preparatory regimen. A thorough review of adults with this type of late renal dysfunction has not previously been described. Fourteen of 103 evaluable adult patients undergoing allogeneic (96) or autologous (7) bone marrow transplantation, predominantly for leukemia and lymphomas, at the Medical College of Wisconsin (Milwaukee, WI) have had a syndrome of renal insufficiency characterized by increased serum creatinine, decreased glomerular filtration rate, anemia, and hypertension. This syndrome developed at a median of 9 months (range, 4.5 to 26 months) posttransplantation in the absence of specific identifiable causes. The cumulative probability of having this renal dysfunction is 20% at 1 year. Renal biopsies performed on seven of these cases showed the endothelium widely separated from the basement membrane, extreme thickening of the glomerular basement membrane, and microthrombi. Previous chemotherapy, antibiotics, and antifungals as well as cyclosporin may add to and possibly potentiate a primary chemoradiation marrow transplant renal injury, but this clinical syndrome is most analogous to clinical and experimental models of radiation nephritis. This late marrow transplant-associated nephritis should be recognized as a potentially limiting factor in the use of some intensive chemoradiation conditioning regimens used for BMT. Some selective attenuation of the radiation to the kidneys may decrease the incidence of this renal dysfunction.

    Severe aplastic anemia (SAA) is a life-threatening hematopoietic stem cell disorder that is treated with bone marrow transplantation (BMT) or immunosuppressive therapy (IST). The management of patients with refractory SAA after IST is a major challenge. Alternative donor BMT is the best chance for cure in refractory SAA, but morbidity and mortality from graft failure and complications of graft-versus-host disease (GVHD) have limited enthusiasm for this approach. Here, we employed post-transplantation high-dose cyclophosphamide in an effort to safely expand the donor pool in 16 consecutive patients with refractory SAA who did not have a matched sibling donor. Between July 2011 and August 2016, 16 patients underwent allogeneic (allo) BMT for refractory SAA from 13 haploidentical donors and 3 unrelated donors. The nonmyeloablative conditioning regimen consisted of antithymocyte globulin, fludarabine, low-dose cyclophosphamide, and total body irradiation. Post-transplantation cyclophosphamide 50 mg/kg/day i.v. on days +3 and +4 was administered for GVHD prophylaxis. Additionally, patients received mycophenolate mofetil on days +5 through 35 and tacrolimus from day +5 through 1 year. The median age of the patients at the time of transplantation was 30 (range, 11 to 69) years. The median time to neutrophil recovery over 1000 × 103/mm3 for 3 consecutive days was 19 (range, 16 to 27) days, to red cell engraftment was 25 (range, 2 to 58) days, and to last platelet transfusion to keep platelets counts over 50 × 103/mm3 was 27.5 (range, 22 to 108) days. Graft failure, primary or secondary, was not seen in any of the patients. All 16 patients are alive, transfusion independent, and without evidence of clonality. The median follow-up is 21 (range, 3 to 64) months. Two patients had grade 1 or 2 skin-only acute GVHD. These same 2 also had mild chronic GVHD of the skin/mouth requiring systemic steroids. One of these GVHD patients was able to come off all IST by 15 months and the

    In vivo T cell depletion with 100 mg alemtuzumab prevents graft-versus-host disease (GVHD) in reduced intensity conditioned transplants but is associated with delayed immune reconstitution, a higher risk of infection and relapse. De-escalation studies have shown that a reduced dose of 30 mg is as effective as 100 mg in preventing GVHD in matched related donor (MRD) transplants. Dose reduction in matched unrelated donor (MUD) transplants is feasible but the comparative efficacy of alemtuzumab in this setting is not known and opinions vary widely concerning the optimal level of GVHD prophylaxis that should be achieved. Through retrospective analysis we made an objective comparison of MUD transplants receiving an empirically reduced dose of 60 mg, with MRD transplants receiving a 30 mg dose. We observed proportionate levels of alemtuzumab according to dose but an inverse relationship with body surface area particularly in MRD transplants. MUD transplants experienced more acute and chronic GVHD, higher T cell chimerism, more sustained use of ciclosporin and less need for donor lymphocyte infusion than MRD transplants. Thus, doubling the dose of alemtuzumab to 60 mg did not provide equivalent prevention of GVHD after MUD transplant although there was no difference in non-relapse mortality or survival compared with MRD transplants.

  7. Successful Treatment of a Hepatitis C-Positive Patient Who Received Kidney Transplant From a Hepatitis C-Positive Donor: A Case Report.

    Papayannis, Ioannis; Patel, P


    Kidney transplantation from hepatitis C virus (HCV)-positive donors to HCV-positive recipients has always been controversial regarding the safety and the outcomes. In the posttransplant period, treatment of hepatitis C with interferon-based regimens could lead to serious side effects. A patient with chronic hepatitis C and nephropathy, on dialysis, underwent renal transplantation from an HCV-positive donor and received direct-acting antiviral (DAA) drugs thereafter. His renal and liver functions, as well as the hepatitis C viral load, were evaluated at predetermined intervals throughout and after his treatment. Patient's viral load was undetectable 4, 12, and 24 weeks after initiation of his treatment. Renal and liver functions were maintained at baseline, with no evidence of transplant rejection. Our clinical case is one of the few examples in the medical literature that shows successful suppression of replication of HCV in an HCV-infected kidney transplant candidate who received within 2 months of listing a deceased donor kidney transplant from an HCV-infected donor. The recipient was treated with DAAs, and this case illustrates potential safety and efficacy of this approach.

  8. Living kidney transplantation between brothers with unrecognized renal amyloidosis as the first manifestation of familial Mediterranean fever: a case report.

    Peces, Ramón; Afonso, Sara; Peces, Carlos; Nevado, Julián; Selgas, Rafael


    Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent episodes of fever and polyserositis and by the onset of reactive amyloid-associated amyloidosis. Amyloidosis due to familial Mediterranean fever can lead to end-stage renal disease, culminating in kidney transplantation for some patients. In this study, we report the clinical outcome of two brothers with familial Mediterranean fever who were the inadvertent donor and recipient, respectively, of a kidney. Subsequently, they were diagnosed with renal amyloidosis secondary to familial Mediterranean fever and were successfully treated with anakinra and colchicine. Two brothers with familial Mediterranean fever and renal amyloidosis were the inadvertent donor and recipient, respectively, of a kidney. The recipient had presented recurrent acute febrile episodes of familial Mediterranean fever, developed nephrotic syndrome secondary to amyloidosis and needed bilateral nephrectomy and chronic dialysis. His elder brother, in apparent good health, donated his left kidney to his brother. Immediately after the kidney transplantation, both the donor and recipient presented massive proteinuria, impaired renal function and elevated serum amyloid A levels. Biopsies of the brothers' kidneys showed amyloidosis. Genetic studies thereafter revealed a homozygous variant for the MEFV gene (NM_000243.2.c.2082G > A; p.M694I) in both brothers. At this point, both the donor and recipient were treated with colchicine and anakinra, resulting in improved renal function, decreased proteinuria, undetectable serum amyloid A levels and stable renal function at 62 months of follow-up and no major adverse effects. In familial Mediterranean fever, analyses of the MEFV gene should be performed in potential live kidney donors from a direct family member (either between siblings or between parents and children). In addition, genetic studies are required when consanguinity is suspected between members involved in

  9. Dyslipidaemia among renal transplant recipients: cyclosporine versus tacrolimus.

    Fazal, Muhammad Asim; Idrees, Muhammad Khalid; Akhtar, Syed Fazal


    To compare new onset dyslipidaemia in live-related renal transplant recipients taking cyclosporine versus tacrolimus after 3 months of therapy. The randomised controlled trial was conducted at the Sindh Institute of Urology and Transplantation (SIUT) Karachi, from September 2010 to April 2011, and included 182 End Stage Renal Disease patients on maintenance haemodialysis with pre-transplant normal lipid profile. The patients, who had live-related renal transplant, were randomly allocated to two equal groups using lottery. Group A received cyclosporine (3 mg/kg) and group B was treated with tacrolimus (0.1 mg/kg). All patients had pre-transplant fasting lipid profile checked when they were on maintenance haemodialysis and 3 months after renal transplantation. Serum fasting lipid profile was collected by taking 5 ml blood by venipuncture after an overnight fast of 9-12 hours. SPSS 10 was used for statistical analyses. Of the 182 patients, 144 (79.1%) were males and 38 (20.9%) were females. The overall mean age was 30.18 +/- 9.57 years, and the mean weight was 54.41 +/- 11.144 kg. Significant difference was not observed between the two groups regarding age and weight of the patients. Dyslipidaemia was found in 115(63.2%) subjects; 61(67%) in group A and 54 (59.3%) in group B. There was no statistical difference (p=0.28) when comparison was done after 3 months of therapy. The occurrence of new onset hyperlipidaemia is similar in renal transplant recipients receiving either cyclosporine or tacrolimus in first 3 months post-transplant, but there is room for more research in this field as dyslipidaemia following successful renal transplantation is a frequent and persistent complication.

    Pruthi, Rishi; Casula, Anna; MacPhee, Iain


    There was a 2% fall in overall renal transplant numbers in 2014, with a significant fall in kidney donation from donors after circulatory death (10%). In 2014, death-censored renal transplant failure rates in prevalent patients were similar to previous years at 2.4% per annum. Transplant patient death rates remained stable at 2.3 per 100 patient years. The median age of incident and prevalent renal transplant patients in the UK was 50.6 and 53.3 years respectively. The median eGFR of prevalent renal transplant recipients was 52.5 ml/min/1.73 m2. The median eGFR of patients one year after transplantation was 57.4 ml/min/1.73 m2 post live transplant, 53.6 ml/min/1.73 m2 post brainstem death transplant and 50.1 ml/min/1.73 m2 post circulatory death transplant. In 2014, 13% of prevalent transplant patients had eGFR ,30 ml/min/1.73 m2. The median decline in eGFR slope beyond the first year after transplantation was −0.48 ml/min/1.73 m2/year.In 2014, malignancy (26%) and infection (24%) remained the commonest causes of death in patients with a functioning renal transplant.

    Aim Patients with a solid organ transplant can have many different complications in the mouth, as a result of immunosuppression and side effects of drugs. The aim of this study was to examine the frequency and type of oral lesions in renal transplant patients, dental status, oral hygiene, oral lesions related to drugs which patients take and the time of transplantation as well as the frequency of patient’s visits to the dentist in the post-transplant period. Material and methods The study was performed in a period of two years and included 100 subjects with a renal transplant during their regular control visits to the Department of Nephrology and Dialysis, Clinical Hospital Centre Zagreb and the Department of Oral Medicine, School of Dental Medicine, University of Zagreb and 100 randomly selected control subjects at the Department of Endodontics and Restorative Dentistry, School of Dental Medicine, University of Zagreb. Results Results showed a significantly higher incidence of oral lesions in patients with renal transplant (31%) compared to control subjects. The most frequent were erythematous (inflammatory changes), keratotic lesions and gingival hyperplasia. The average DMFT index was significantly lower in patients with renal transplant than in the control group. One third of patients had a subjective feeling of dry mouth. Oral hygiene was poor overall, and only a small number of subjects used the additional sustainers for oral hygiene. Most patients did not visit the dentist after the transplantation. Conclusion Renal transplant patients need a comprehensive and regular dental care during the pre- and post-transplant period and a doctor of dental medicine should be part of a multidisciplinary team of medical specialists.

  12. Inhibition of chemokine-glycosaminoglycan interactions in donor tissue reduces mouse allograft vasculopathy and transplant rejection.

    Erbin Dai

    Full Text Available BACKGROUND: Binding of chemokines to glycosaminoglycans (GAGs is classically described as initiating inflammatory cell migration and creating tissue chemokine gradients that direct local leukocyte chemotaxis into damaged or transplanted tissues. While chemokine-receptor binding has been extensively studied during allograft transplantation, effects of glycosaminoglycan (GAG interactions with chemokines on transplant longevity are less well known. Here we examine the impact of interrupting chemokine-GAG interactions and chemokine-receptor interactions, both locally and systemically, on vascular disease in allografts. METHODOLOGY/PRINCIPAL FINDINGS: Analysis of GAG or CC chemokine receptor 2 (CCR2 deficiency were coupled with the infusion of viral chemokine modulating proteins (CMPs in mouse aortic allograft transplants (n = 239 mice. Inflammatory cell invasion and neointimal hyperplasia were significantly reduced in N-deacetylase-N-sulfotransferase-1 (Ndst1(f/fTekCre(+ heparan sulfate (GAG-deficient (Ndst1(-/-, p<0.044 and CCR2-deficient (Ccr2(-/-, p<0.04 donor transplants. Donor tissue GAG or CCR2 deficiency markedly reduced inflammation and vasculopathy, whereas recipient deficiencies did not. Treatment with three CMPs was also investigated; Poxviral M-T1 blocks CC chemokine receptor binding, M-T7 blocks C, CC, and CXC GAG binding, and herpesviral M3 binds receptor and GAG binding for all classes. M-T7 reduced intimal hyperplasia in wild type (WT (Ccr2(+/+, p< or =0.003 and Ccr2(-/-, prenal allograft transplants (p< or =0.001. CONCLUSIONS/SIGNIFICANCE: Interruption of chemokine-GAG interactions, even in the absence of chemokine

  13. Live donor hepatectomy for liver transplantation in Egypt: Lessons learned

    Emad Kamel


    Full Text Available Purpose: To retrospectively review anesthesia and intensive care management of 145 consented volunteers subjected to right lobe or left hepatectomy between 2003 and 2011. Methods: After local ethics committee approval, anesthetic and intensive care charts, blood transfusion requirements, laboratory data, complications and outcome of donors were analyzed. Results: One hundred and forty-three volunteers successfully tolerated the surgery with no blood transfusion requirements, but with a morbidity rate of (50.1%. The most frequent complication was infection (21.1% (intraabdominal collections, followed by biliary leak (18.2%. Two donors had major complications: one had portal vein thrombosis (PVT treated with vascular stent. This patient recovered fully. The other donor had serious intraoperative bleeding and developed postoperative PVT and liver and renal failure. He died after 12 days despite intensive treatment. He was later reported among a series of fatalities from other centers worldwide. Epidural analgesia was delivered safely (n=90 with no epidural hematoma despite significantly elevated prothrombin time (PT and international normalization ratio (INR postoperatively, reaching the maximum on Day 1 (16.9±2.5 s and 1.4±0.2, P<0.05 when compared with baseline. Hypophosphatemia and hypomagnesemia were frequently encountered. Total Mg and phosphorus blood levels declined significantly to 1.05±0.18 mg/dL on Day 1 and 2.3±0.83 mg/dL on Day 3 postoperatively. Conclusions: Coagulation and electrolytes need to be monitored perioperatively and replaced adequately. PT and INR monitoring postoperatively is still necessary for best timing of epidural catheter removal. Live donor hepatectomy could be performed without blood transfusion. Bile leak and associated infection of abdominal collections requires further effort to better identify biliary leaks and modify the surgical closure of the bile ducts. Donor hepatectomy is definitely not a complication
