Sample records for renal transplant patients

  1. 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.

  2. 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

    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.

  4. 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.

  6. Renal transplantation in HIV patients: A series of four cases


    Human immunodeficiency virus (HIV) infection in a patient with end-stage renal disease was considered a contraindication for renal transplantation till now despite the advent of highly active antiretroviral therapy with the apprehension that immunosuppression would further jeopardize the already compromised immune status of the patients. Renal transplantation in HIV patients is rare in developing countries including ours. Here we report a series of four cases of renal transplantation in HIV p...

  7. Challenges of valve surgeries in post-renal transplant patients.

    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.

  8. [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.

  9. 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.

    Kamper, A L; Nielsen, A H


    BACKGROUND: The aim of the study was to evaluate the uricosuric effect of the angiotensin II receptor antagonist, losartan, in hypertensive patients with renal transplants who are treated with cyclosporin A (CsA). METHODS: Twenty-six patients with stable renal function and hypertension, 16 men......-daily administration of 50 mg of losartan in hypertensive CsA-treated patients with renal transplants caused a 17% increase in FE(uric acid) and an 8% fall in plasma uric acid....

  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.

  12. 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.

    Full Text Available We report the case of successful renal allogeneic transplantation and treatment in a 56-year-old patient with haemophilia B at Hematology Research Center. He has received replacement therapy by factor IX since 2010. The transplant is marked with good renal function during 13 post-transplant months without episodes of rejection or bleeding complications. The complicated surgical interventions are possible in patients with haemophilia В аnd end-stage chronic renal failure in the presence of replacement therapy of IX factor for the purpose of achievement of optimum hemostasis.

  14. Peritonitis in peritoneal dialysis patients after renal transplantation

    Bakir, N; Surachno, S; Sluiter, WJ; Struijk, DG


    Background. The occurrence of peritonitis in peritoneal dialysis patients after renal transplantation during immunosuppression might increase morbidity and mortality. Hence the timing of catheter removal is still controversial. The associated risk factors of this complication have not been analyzed.

  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. 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.

  18. [Visceral leishmaniasis and pregnancy in renal transplanted patient: case report].

    Silva, Jaqueline de Almeida; Araújo, Ivan de Melo; Pavanetti, Luiz Carlos; Okamoto, Liene Shigaki; Dias, Mônica


    Visceral leishmaniasis (VL) is a severe and potentially fatal disease caused by different Leishmania species, Leishmania chagasi prevailing in Brazil. Main symptoms include fever, malaise, anorexia, weight loss and abdominal enlargement with typically occurring hepatosplenomegaly Currently, VL is considered an opportunistic infection in immunocompromised hosts, including solid organ transplanted patients. The present study reports a case of VL associated to pregnancy after renal transplantation.

  19. Steroid withdrawal in renal transplant patients: the Irish experience.

    Phelan, P J


    BACKGROUND: Steroid therapy is associated with significant morbidity in renal transplant recipients. However, there is concern that steroid withdrawal will adversely affect outcome. METHODS: We report on 241 renal transplant recipients on different doses of corticosteroids at 3 months (zero, <\\/= 5 mg\\/day, > 5 mg\\/day). Parameters analysed included blood pressure, lipid profile, weight change, new onset diabetes after transplantation (NODAT), allograft survival and acute rejection. RESULTS: Elimination of corticosteroids had no impact on allograft survival at 1 year. There were no cases of NODAT in the steroid withdrawal group compared with over 7% in each of the steroid groups. There were no significant improvements in weight gain, blood pressure control or total cholesterol with withdrawal of steroids before 3 months. CONCLUSIONS: In renal transplant patients treated with tacrolimus and mycophenolate, early withdrawal of steroids does not appear to adversely affect allograft outcome at 1 year. It may result in less NODAT.

    Nicodemo, A C; Odongo, F C A; Doi, A M; Sampaio, J L M


    We present the first report, to our knowledge, of a renal abscess cause by an infection from Gordonia terrae in a kidney transplant patient. The patient simultaneously had pulmonary tuberculosis and a perirenal allograft abscess caused by G. terrae. After treatment with imipenem, in addition to anti-tuberculous drugs, the patient was cured.

  1. Vaccination in Renal Transplant Patients (VcRtp study)

    Rathore, F


    Adverse outcomes of influenza & pneumococcal infections in solid organ transplant recipients have been well documented. Vaccinations are therefore recommended by multiple guidelines. Despite emerging evidence of the safety & effectiveness among immunosuppressed patients, most vaccines are still underutilized, we conducted a survey among the renal transplant patients in Beaumont Hospital to determine the awareness and uptake of vaccinations. Questionnaires were handed to patients during a clinic visit over a span of 2 weeks and 250 questionnaires were posted out to randomly selected transplant patients, The Questionnaire addressed various aspects including the awareness of importance of vaccinations, source of information, if they were up to date with the vaccines & where did they receive it?

  2. Pregnancy in a patient with Goodpasture syndrome and renal transplantation.

    Wells, S R; Kuller, J A; Thorp, J M


    Patients with Goodpasture syndrome have classically had decreased fertility and associated pregnancy wastage. Renal transplantation can increase the likelihood of successful pregnancy. We describe a patient who carried a pregnancy into the third trimester and had a good neonatal outcome. However, she developed superimposed preeclampsia with subsequent graft rejection.

  3. Can patients with schizophrenia undergo renal transplantation with success?

    Saoussen Bouhlel


    Full Text Available We report a case of a 41-year-old man suffering from paranoid schizophrenia. The patient has been consulting in our psychiatric hospital since he was 29 years old. Eight years later, he developed kidney failure and required peritoneal dialysis. After more than two years, the nephrology team indicated a renal transplantation and his brother suggested giving his kidney. There were no obstacles for transplantation in the immune and histological compatibilities; the psychiatric staff decided to check the patient′s compliance with medication. The patient was compliant to all his medications and to the salt-free diet after the transplant operation. Few weeks later, he developed steroid-induced diabetes. Through the last two years, he had psychotic exacerbations with major anxiety and fear of losing the transplant. These relapses were managed by increasing doses of antipsychotics without need for hospitalization. At the present time, three years after transplantation, the nephrologists are decreasing the immunosuppressive agents and the steroids. The renal function is optimum and the diabetes is stabilized. This case exemplifies the potential for schizophrenic patients to undergo renal transplantation and to comply with follow-up medical care through a close cooperation between the patient′s family, the psychiatric staff and the nephrology team.

  4. Renal transplantation in HIV-infected patients: 2010 update.

    Trullas, Joan C; Cofan, Federico; Tuset, Montse; Ricart, María J; Brunet, Mercedes; Cervera, Carlos; Manzardo, Christian; López-Dieguez, María; Oppenheimer, Federico; Moreno, Asuncion; Campistol, Josep M; Miro, Jose M


    The prognosis of human immunodeficiency virus (HIV) infection has improved in recent years with the introduction of antiretroviral treatment. While the frequency of AIDS-defining events has decreased as a cause of death, mortality from non-AIDS-related events including end-stage renal diseases has increased. The etiology of chronic kidney disease is multifactorial: immune-mediated glomerulonephritis, HIV-associated nephropathy, thrombotic microangiopathies, and so on. HIV infection is no longer a contraindication to transplantation and is becoming standard therapy in most developed countries. The HIV criteria used to select patients for renal transplantation are similar in Europe and North America. Current criteria state that prior opportunistic infections are not a strict exclusion criterion, but patients must have a CD4+ count above 200 cells/mm(3) and a HIV-1 RNA viral load suppressible with treatment. In recent years, more than 200 renal transplants have been performed in HIV-infected patients worldwide, and mid-term patient and graft survival rates have been similar to that of HIV-negative patients. The main issues in post-transplant period are pharmacokinetic interactions between antiretrovirals and immunosuppressants, a high rate of acute rejection, the management of hepatitis C virus coinfection, and the high cardiovascular risk after transplantation. More studies are needed to determine the most appropriate antiretroviral and immunosuppressive regimens and the long-term outcome of HIV infection and kidney graft.

  5. 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

  6. Renal transplant improves pulmonary hypertension in patients with end stage renal disease

    Bozbas Serife


    Full Text Available Abstract Background Pulmonary hypertension (PH is present in a significant proportion of patients with end stage renal disease (ESRD and is of prognostic importance. Data on the effect of renal transplant on PH is very limited. In this study, the aim was to examine the effect of renal transplant on systolic pulmonary artery pressure (SPAP determined by Doppler echocardiography. Methods Analysis was performed on the records of 500 consecutive patients who underwent renal transplant at our center between the years 1999 to 2008. The prevalence of PH in the preoperative assessment period was established. Patients were diagnosed as having PH when measured SPAP values were > 35 mm Hg. Results Pulmonary hypertension was detected in 85 of the 500 (17% patients under pre-transplant evaluation. At post-transplant follow up Doppler echocardiographic examination was performed on 50 of the 85 patients. After exclusion of 8 cases (1 due to massive pulmonary thromboemboli; 7 due to graft failure requiring dialysis therapy analyses were performed on 42 patients who had undergone both pre- and post-transplant echocardiographic examination. Mean SPAP at pre-transplant evaluation was 45.9 ± 8.8 mm Hg and in 6 (14.3% cases SPAP was above 50 mm Hg. Compared to pre-transplant values, a significant decrease was observed in mean SPAP values in an average of 53 months of postoperative follow up (41.8 ± 7.4 mm Hg vs. 45.9 ± 8.8 mm Hg, p Conclusion These findings indicate that patients with ESRD accompanied by PH may benefit from renal transplant. Further research is required for more concrete conclusions to be drawn on this subject.

  7. Early onset primary pulmonary cryptococcosis in a renal transplant patient

    Tarai B


    Full Text Available We report a case of primary pulmonary cryptococcosis in a post-renal transplant patient. A 65-year-old male renal transplant patient was admitted to the hospital with a low grade fever of 1 month, radiologically mimicking tuberculosis (TB. Broncho-alveolar fluid (BAL shows capsulated yeast, and Cryptococcus neoformans was grown on culture supported by cytology and histopathological examination. Cryptococcal antigen was positive (32-fold in serum and was negative in cerebrospinal fluid (CSF. The patient was given amphotericin B and 5-flucytosine and clinical improvement was seen on a weekly follow up. The serum cryptococcal antigen test might contribute to the early detection and treatment of pulmonary cryptococcosis. The results of antifungal susceptibility were aid in selecting the drug of choice for treatment.

  8. Steroid withdrawal in renal transplant patients: the Irish experience.

    Phelan, P J


    BACKGROUND: Steroid therapy is associated with significant morbidity in renal transplant recipients. However, there is concern that steroid withdrawal will adversely affect outcome. METHODS: We report on 241 renal transplant recipients on different doses of corticosteroids at 3 months (zero, ≤5 mg\\/day, >5 mg\\/day). Parameters analysed included blood pressure, lipid profile, weight change, new onset diabetes after transplantation (NODAT), allograft survival and acute rejection. RESULTS: Elimination of corticosteroids had no impact on allograft survival at 1 year. There were no cases of NODAT in the steroid withdrawal group compared with over 7% in each of the steroid groups. There were no significant improvements in weight gain, blood pressure control or total cholesterol with withdrawal of steroids before 3 months. CONCLUSIONS: In renal transplant patients treated with tacrolimus and mycophenolate, early withdrawal of steroids does not appear to adversely affect allograft outcome at 1 year. It may result in less NODAT.

  9. Total peripheral vascular resistance in pediatric renal transplant patients.

    Matteucci, Maria Chiara; Giordano, Ugo; Calzolari, Armando; Rizzoni, Gianfranco


    Abnormal cardiovascular reactivity at rest and during physical exercise may be a risk factor for left ventricular hypertrophy (LVH) in pediatric renal transplanted (Tx) patients. Data on total peripheral vascular resistance (TPR) are not available. Eleven renal Tx patients treated with cyclosporine (7 females and 4 males; mean age 14.6 +/- 3.3 years; mean time since transplantation 43 +/- 35 months) were evaluated for 24-hour blood pressure (BP), TPR and echocardiographic left ventricular mass (LVM). TPR values of patients were compared with data of a group of 11 healthy controls matched for sex and age. Twenty-four-hour ambulatory blood pressure monitoring showed that all but one patient had normal daytime BP values and six patients showed a reduced or inverse nocturnal dip. LVH was found in 72% of the patients. In comparison with healthy controls, patients showed significantly elevated TPR at rest and during exercise suggesting an increased vascular tone. The degree of LVH in these patients is severe and appears disproportionate to the BP values. The high incidence of LVH can reflect an augmented cardiovascular reactivity associated with a disturbed circadian pattern. The increase in TPR and the reduction of the nocturnal fall of BP also might contribute to the development of LVH in young renal Tx patients.

  10. Bariatric Surgery as a Bridge to Renal Transplantation in Patients with End-Stage Renal Disease.

    Al-Bahri, Shadi; Fakhry, Tannous K; Gonzalvo, John Paul; Murr, Michel M


    Obesity is a relative contraindication to organ transplantation. Preliminary reports suggest that bariatric surgery may be used as a bridge to transplantation in patients who are not eligible for transplantation because of morbid obesity. The Bariatric Center at Tampa General Hospital, University of South Florida, Tampa, Florida. We reviewed the outcomes of 16 consecutive patients on hemodialysis for end-stage renal disease (ESRD) who underwent bariatric surgery from 1998 to 2016. Demographics, comorbidities, weight loss, as well as transplant status were reported. Data is mean ± SD. Six men and ten women aged 43-66 years (median = 54 years) underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 12), laparoscopic adjustable gastric banding (LAGB, n = 3), or laparoscopic sleeve gastrectomy (LSG, n = 1). Preoperative BMI was 48 ± 8 kg/m(2). Follow-up to date was 1-10 years (median = 2.8 years); postoperative BMI was 31 ± 7 kg/m(2); %EBWL was 62 ± 24. Four patients underwent renal transplantation (25%) between 2.5-5 years after bariatric surgery. Five patients are currently listed for transplantation. Five patients were not listed for transplantation due to persistent comorbidities; two of these patients died as a consequence of their comorbidities (12.5%) more than 1 year after bariatric surgery. Two patients were lost to follow-up (12.5%). Bariatric surgery is effective in patients with ESRD and improves access to renal transplantation. Bariatric surgery offers a safe approach to weight loss and improvement in comorbidities in the majority of patients. Referrals of transplant candidates with obesity for bariatric surgery should be considered early in the course of ESRD.

  11. Quantitative scintigraphic parameters for the assessment of renal transplant patients

    El Maghraby, T.A.F.; Eck-Smit, B.L.F. van; Pauwels, E.K.J. [Department of Radiology, Division of Nuclear Medicine, Leiden University Medical Centre, P.O. Box 9600, 2300 RC Leiden (Netherlands); Fijter, J.W. de [Department of Nephrology, Leiden University Medical Centre, Leiden (Netherlands)


    Radionuclide renal diagnostic studies play an important role in assessing renal allograft function especially in the early post transplant period. In the last two decades various quantitative parameters have been derived from the radionuclide renogram to facilitate and confirm the changes in perfusion and/or function of the kidney allograft. In this review article we discuss the quantitative parameters that have been used to assess graft condition with emphasis on the early post-operative period. These quantitative methods were divided into parameters used for assessing renal graft perfusion and parameters used for evaluating parenchymal function. The blood flow in renal transplants can be quantified by measuring (a) the rate of activity appearance in the kidney graft; (b) the ratio of the integral activity under the transplanted kidney and arterial curves e.g. Hilson's perfusion index and Kircher's kidney/aortic ratio; (c) calculating the renal vascular transit time by deconvolution analysis. The literature overview on these parameters showed us that they have some practical disadvantages of requiring high quality bolus injection and numerical variations related to changes in the site and size of regions of interest. In addition, the perfusion parameter values suffer from significant overlap when various graft pathologies coexist. Quantitative evaluation of the graft parenchymal extraction and excretion was assessed by parameters derived from {sup 123}I/{sup 131}I-OIH,{sup 99m}Tc-DTPA or {sup 99m}Tc-MAG3 renograms. We review in this article a number of parenchymal parameters which include (1) plasma clearance methods like glomerular filtration rate (GFR) and effective renal plasma flow (ERPF); (2) renal transit times such as parenchymal mean transit time, T{sub max}, T{sub 1/2}; (3) parenchymal uptake and excretion indices as the accumulation index, graft uptake capacity at 2 and 10 min, excretion index and elimination index. These indices, however, are

    Full Text Available Today the problem of better life quality of patients with end stage renal disease and after renal transplantation and their sexual adaptation is considered to be more impotent. The clinical part of the investigation is the obser- vation of 205 patients – men with terminal stage renal disease. Erectile dysfunction is represented in 91,4% (64 of patients getting haemodialysis, 92,3% (24 of patients getting peritoneal dialysis, 61,5% (67 of patients after renal transplantation. According to International Index of Erectile Function the mean score of erectile function is 16,7 ± 5,2 in haemodialysis patients, 19,46 ± 3,6 in peritoneal dialysis patients, 21,9 ± 5,6 in patients after renal transplantation. The analysis revealed great prevalence of erectile dysfunction and interest in improvement among the patients with end stage renal disease and after renal transplantation

  13. Aspergillus Pericarditis with Tamponade in a Renal Transplant Patient

    Lekkham, Rapeepat; Climaco, Antoinette


    Aspergillus pericarditis is a rare and life-threatening infection in immunosuppressed patients. It has nonspecific clinical manifestations that often mimic other disease entities especially in patients who have extensive comorbidities. Diagnosis is oftentimes delayed and rarely done antemortem. A high degree of suspicion in immunocompromised patients is necessary for evaluation and timely diagnosis. This is a case of Aspergillus pericarditis with cardiac tamponade in a renal transplant patient with liver cirrhosis. Two months after transplant, he developed decompensation of his cirrhosis from hepatitis C, acute cellular rejection, and Kluyvera bacteremia, followed by vancomycin-resistant Enterococcus faecium (VRE) bacteremia. Four months after transplant, the patient presented with lethargy and fluid overload. He subsequently developed shock and ventilator-dependent respiratory failure. An echocardiogram showed pericardial effusion with cardiac tamponade. He had emergent pericardiocentesis that showed purulent drainage. He was started on broad-spectrum antibiotics. Amphotericin B was initiated when the pericardial fluid grew mold that was later identified as Aspergillus fumigatus. The patient quickly decompensated and expired. PMID:28316844

  14. Prostatectomy for localized prostate cancer to prepare for renal transplantation in end-stage renal disease patients.

    Tillou, Xavier; Chahwan, Charles; Le Gal, Sophie; Bensadoun, Henri; Doerfler, Arnaud


    Surgical difficulties of renal transplantation related to prostate cancer (PC) treatment and the results of renal transplantation after radical prostatectomy are currently poorly known, as well as oncological follow-up before and after renal transplantation. We performed a retrospective study including all patients diagnosed with PC before renal transplantation in our department. Nineteen patients were included between August 2003 and December 2013. The mean age at diagnosis of PC was 61.7 years (range 51.4-71.1). PSA mean level at diagnosis was 8.5 ng/ml (range 4.8-20). Fourteen had a retro-pubic and 5 a laparoscopic prostatectomy. Three patients underwent radiotherapy for positive surgical margins or extra-capsular extension. Fourteen patients were transplanted. The mean time lapse between prostatectomy and kidney transplantation was 32.8 months (range 14-71). Seven recipients (50%) were transplanted less than 24 months after prostatectomy. Post-transplantation surgical complications were not significantly related to dissection difficulties (p=0.2). No recurrence of PC was observed after renal transplantation, with a mean follow-up of 38 months (range 6-77.9). Prostate cancer discovered before renal transplantation should be treated by radical prostatectomy to assess recurrence risk. If the PC is at low risk of recurrence, it seems possible to shorten the 2-year period of oncologic follow-up before transplantation called for in current recommendations.

  15. 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.

    Carina Nilsen Moreno


    Full Text Available Este artigo de revisão tem como objetivo apresentar as principais considerações sobre o transplante renal em pacientes HIV positivos. Na última década, com o advento da terapia antirretroviral de alta atividade (Highly Active Antiretroviral Therapy - HAART, a evolução dos pacientes infectados pelo vírus da imunodeficiência humana (Human Immunodeficiency Virus - HIV mudou significativamente, com uma acentuada diminuição das taxas de morbimortalidade nesta população. Neste contexto, o número de pacientes HIV positivos com doença renal crônica com necessidade de terapia dialítica vem aumentando progressivamente. Diante desta nova realidade, o transplante renal, antes considerado uma contraindicação absoluta para tais pacientes, passou a ser considerado uma alternativa de terapia substitutiva da função renal. Questões sobre o uso de imunossupressores neste grupo de pacientes e sua possível ação aumentando a replicação do HIV, além do risco de infecções oportunistas e de desenvolvimento de neoplasias, são amplamente discutidas. Porém, a experiência clínica nessa área mostra que a utilização dessas drogas para pacientes soropositivos parece ser segura, inclusive com relatos de ação antirretroviral de algumas das drogas imunossupressoras. Apesar disso, ainda hoje existem poucos relatos de transplantes nesta população. Em resumo, os dados da literatura sugerem que o transplante renal, seguindo critérios de seleção dos pacientes, parece ser uma alternativa segura como terapia de substituição renal em pacientes HIV positivos.This review presents current considerations for renal transplantation in HIV patients.

    Moore, Jason


    It remains unclear whether low hemoglobin levels are associated with increased mortality or graft loss after renal transplantation. This study assessed the relationship of hemoglobin levels with patient and graft survival in 3859 patients with functioning renal transplants more than 6-months posttransplantation.

  19. The use of everolimus in renal-transplant patients

    Julio Pascual


    Full Text Available Julio PascualServicio de Nefrología, Hospital Ramón y Cajal, 28034 Madrid, SpainAbstract: Despite advances in immunosuppressive therapy, long-term renal-transplantation outcomes have not significantly improved over the last decade. The nephrotoxicity of calcineurin inhibitors (CNIs is an important cause of chronic allograft nephropathy (CAN, the major driver of long-term graft loss. Everolimus is a proliferation signal inhibitor with a mechanism of action that is distinct from CNIs. The efficacy and tolerability of everolimus in renal-transplant recipients have been established in a wide range of clinical trials. Importantly, synergism between everolimus and the CNI cyclosporine (CsA permits CsA dose reduction, enabling nephrotoxicity to be minimized without compromising efficacy. Currently, everolimus is being investigated in regimens where reduced exposure CNIs are used from the initial post-transplant period to improve renal function and prevent CAN. By inhibiting the proliferation of smooth muscle cells, everolimus may itself delay the progression or development of CAN. Although everolimus is associated with specific side effects, these can generally be managed. By targeting the main causes of short- and long-term graft loss, everolimus has a key role to play in renal transplantation, which is being explored further in a number of ongoing Phase III–IV trials.Keywords: calcineurin inhibitors, chronic allograft nephropathy, cyclosporine, everolimus, renal function, renal transplantation

  20. Induction treatment of previously undiagnosed ANCA-associated vasculitis in a renal transplant patient with Rituximab

    Graham-Brown, M. P. M.; Aljayyousi, R.; Baines, R. J.; Burton, J. O.; Brunskill, N. J.; Furness, P.; Topham, P.


    We report the case of a 40-year-old female transplant patient with undiagnosed ANCA-associated vasculitis (AAV) and renal allograft dysfunction who achieved disease remission with restoration of transplant function following induction therapy with rituximab. There are currently no trial data looking at the use of rituximab for induction of remission of renal transplant patients with AAV. Although recurrence of AAV following renal transplantation is rare, such patients have invariably had multiple previous exposures to induction and maintenance immunosuppressive regimens, often limiting treatment options post-transplantation. In this case, rituximab was well tolerated with no side effects, and was successful in salvaging transplant function. Optimal treatment regimens for relapsed AAV in the transplant population are not known, and clinical trials are needed to evaluate the efficacy and safety of rituximab at inducing and maintaining disease remission in relapsed AAV following transplantation.

  1. Mycobacterium haemophilum Masquerading as Leprosy in a Renal Transplant Patient

    Copeland, Nathanial K.; Arora, Navin S.; Ferguson, Tomas M.


    Opportunistic infections following immunosuppression in solid organ transplant (SOT) patients are common complications with the skin being a common sight of infection. Nontuberculous mycobacteria (NTM) are rare but potential causes of skin infection in SOT patients. We present a case of an adult male immunosuppressed following renal transplantation who presented with an asymptomatic rash for several months. The patient's skin eruption consisted of erythematous papules and plaques coalescing into an annular formation. After failure of the initial empiric therapy, a punch biopsy was performed that demonstrated nerve involvement suspicious for Mycobacterium leprae. However, culture of the biopsy specimen grew acid-fast bacilli that were subsequently identified as M. haemophilum. His rash improved after a prolonged course of clarithromycin and ciprofloxacin. Both organisms are potential causes of opportunistic skin infections and can be difficult to distinguish with similar predilection for skin and other biochemical and genetic similarities. Ultimately they can be distinguished with culture as M. haemophilum will grow in culture and M. leprae will not. This case was unique due to nerve involvement on biopsy which is classically seen on biopsies of leprosy. PMID:24369511

    Full Text Available PURPOSE: Hyperhomocyst(einaemia is an important risk factor for atherosclerosis, which is currently a major cause of death in renal transplant patients. The aim of this study was to assess the influence of immunosuppressive therapy on homocyst(einemia in renal transplant recipients. METHODS: Total serum homocysteine (by high performance liquid chromatography, creatinine, lipid profile, folic acid (by radioimmunoassay-RIA and vitamin B12 (by RIA concentrations were measured in 3 groups. Group I patients (n=20 were under treatment with cyclosporine, azathioprine, and prednisone; group II (n=9 were under treatment with azathioprine and prednisone; and group III (n=7 were composed of renal graft donors for groups I and II. Creatinine, estimated creatinine clearance, cyclosporine trough level, lipid profile, folic acid, and vitamin B12 concentrations and clinical characteristics of patients were assessed with the aim of ascertaining determinants of hyperhomocyst(einemia. RESULTS: Patient ages were 48.8 ± 15.1 yr (group I, 43.3 ± 11.3 yr (group II; and 46.5 ± 14.8 yr (group III. Mean serum homocyst(eine (tHcy concentrations were 18.07 ± 8.29 mmol/l in renal transplant recipients; 16.55 ± 5.6 mmol/l and 21.44 ± 12.1 mmol/l respectively for group I (with cyclosporine and group II (without cyclosporine (NS.

    Rømming Sørensen, Vibeke; Schwartz Sørensen, Søren; Feldt-Rasmussen, Bo


    , the patient survival rates in the two groups were similar. Thereafter, survival among diabetic patients was poor. Mean HbA1c was relatively high, especially after the transplantation, and this may have contributed to the more rapid progression of cardiovascular disease seen in diabetic patients......OBJECTIVE: To study long-term graft and patient survival following renal transplantation in diabetic and non-diabetic patients. MATERIAL AND METHODS: Over the time period 1985-99, 498 transplantations in 399 non-diabetic patients and 68 transplantations in 62 diabetic patients were performed.......

    Garcia Vicente, Ana Maria; Ruiz Solis, Sebastian; Soriano Castrejon, Angel; Poblete Garcia, Victor Manuel; Talavera Rubio, Maria del Prado; Rodado Marina, Sonia; Cortes Romera, Montserrat [Ciudad Real General Hospital (Spain). Dept. of Nuclear Medicine


    Patients with end-stage renal disease have two therapeutic options, dialysis and renal transplantation. Infectious complications occurring in such patients will not only condition the effectiveness of such treatments, but are among the main causes of morbidity and mortality in such cases. Knowledge of the advantages and limitations of nuclear techniques is essential for management of these conditions. (author)

  5. 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.

  6. 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.

  7. Uniparental maternal disomy 6 in a renal transplant patient.

    van den Berg-Loonen, E M; Savelkoul, P; van Hooff, H; van Eede, P; Riesewijk, A; Geraedts, J


    HLA analysis of the family of a renal transplant patient revealed an extremely rare condition. On repeated typings the only demonstrable HLA antigens shown in the propositus were from the maternal haplotype, HLA-A11,-B46,-CW1,-DR14,-DQ1. No paternal antigens could be demonstrated either by serologic or by DNA-typing methods. A paternity investigation was carried out to exclude the possibility of the legal father not being the biological father. The results of this investigation showed a paternity index I = > 20000 and a fatherhood probability W = > 99.995%. Karyotyping of the patient showed two normal chromosomes 6 and no other chromosomal abnormalities. Maternal isodisomy was demonstrated from the analysis of polymorphic DNA markers, involving the short as well as the long arm of chromosome 6. These data are consistent with this patient having the first uniparental maternal disomy 6 reported (inheritance of two identical chromosome 6 haplotypes from the mother and none from the father).

    Buturović-Ponikvar, Jadranka; Gubenšek, Jakob; Arnol, Miha; Bren, Andrej; Kandus, Aljoša; Ponikvar, Rafael


    Kidney transplantation is considered the best renal replacement therapy (RRT) for patients with end-stage renal disease; nevertheless, some dialysis patients refuse to be transplanted. The aim of our registry-based, cross-sectional study was to compare kidney transplant candidates to dialysis patients refusing transplantation. Data were collected from the Slovenian Renal Replacement Therapy Registry database, as of 31 December 2008. Demographic and some RRT data were compared between the groups. There were 1448 dialysis patients, of whom 1343 were treated by hemodialysis and 105 by peritoneal dialysis (PD); 132 (9%) were on the waiting list for transplantation, 208 (14%) were preparing for enrollment (altogether 340 [23%] dialysis patients were kidney transplant candidates); 200 (13.7%) patients were reported to refuse transplantation, all ≤ 65 years of age; 345 (24%) were not enrolled due to medical contraindications, 482 (33%) due to age, and 82 (6%) due to other or unknown reasons. No significant difference was found in age, gender, or presence of diabetes between kidney transplant candidates vs. patients refusing transplantation (mean age 50.5 ± 13.9 vs. 51.3 ± 9.6 years, males 61% vs. 63%, diabetics 18% vs. 17%). The proportion of patients ≤ 65 years old who were refusing transplantation was 28% (187/661) for hemodialysis and 17% (13/79) for PD patients (P = 0.03). There is a considerable group of dialysis patients in Slovenia refusing kidney transplantation. Compared to the kidney transplant candidates, they are similar in age, gender and prevalence of diabetes. Patients treated by peritoneal dialysis refuse kidney transplantation less often than hemodialysis patients.

  11. Renal dysfunction in a renal transplant patient treated concurrently with cyclosporine and imatinib.

    Mulder, Karen E; Egorin, Merrill J; Sawyer, Michael B


    Imatinib mesylate has proven activity in treating locally advanced or metastatic gastrointestinal stromal tumors (GIST). Drug interactions are particularly concerning as imatinib is extensively metabolized by the cytochrome P450 enzyme system. We describe the clinical course of a 72 year-old male with a cadaveric renal transplant requiring cyclosporine that presented with a metastatic GIST and was started on imatinib at the standard dose of 400 mg daily. Imatinib initiation resulted in a decline in renal function with the serum creatinine increasing from 123 μmol/L to 196 μmol/L and an elevation in whole blood cyclosporine concentrations from 79 μg/L to 139 μg/L. No other imatinib toxicities were reported. With discontinuation of imatinib, the serum creatinine returned to baseline as did the whole blood cyclosporine levels. Ultimately, decreasing both the cyclosporine and imatinib dosing was associated with stabilized renal function (serum creatinine 150-186 μmol/L) and cyclosporine concentrations (53-97 μg/L). A prolonged partial response to therapy for 19 months was maintained despite low imatinib trough concentrations measured on two separate occasions (127.1 ng/ml and 139 ng/ml). In our patient, imatinib initiation resulted in renal toxicity most likely due to its interaction with cyclosporine resulting in elevation of the whole blood cyclosporine concentration.

  12. Urinary tract infection in renal transplant patients in Sina University Hospital

    Pourmand MR


    Full Text Available Background: Renal transplantation is the treatment of choice in patients with end-stage  renal disease. Urinary tract infection (UTI is one of the most common complications after renal transplantation and it has serious consequences. The aim of this study was assessing UTIs in renal transplanted patients and evaluation of risk factors associated with post-transplant UTI. Methods: In this prospective study, 173 patients (48 hospitalized patients and 125 outpatients were enrolled in this study. These renal transplant recipients evaluated for bacterial urinary tract infection in urology research center at Sina Hospital. After collecting urine samples from symptomatic and asymptomatic patients, urinalysis and colony count were performed. Identification of bacteria was performed by routine microbiological tests in the Department of Pathobiology, School of Public Health, Tehran, Iran, in 2011.Results: UTI was observed in 47 patients and the most prevalent microorganism was Escherichia coli (E.coli 18(38.2%. Nearly 71% of UTI cases were diagnosed during the first three months post transplantation. Risk factors for post transplant UTI were female gender, age, length of hospitalization and diabetes mellitus. Female patients were more susceptible than males (OR=0.50 and P=0.047 to infection. There were no significant difference between diabetes mellitus and UTI. Most of the isolated bacteria were susceptible to imipenem and resistant to tetracycline and trimethoprim- sulfamethoxazole.Conclusion: Our study confirmed that bacterial infections remain as the most common infectious complication in the early post-transplant period, and antibiogram rather than empirical treatment is needed to find the best effective antibiotics. Moreover, risk factors such as female gender, increased age and length of hospitalization are predisposing factors to increased urinary tract infection in renal transplantation.

  13. BK virus as a potential oncovirus for bladder cancer in a renal transplant patient.

    Yin, Wen-Yao; Lee, Ming-Che; Lai, Ning-Sheng; Lu, Ming-Chi


    Renal transplant patients have high risk for bladder cancer. The reactivation of BK virus is common in renal transplant patients especially in the urinary tract. There was some evidence suggesting that the reactivation of BK virus (BKV) in renal transplant patients may associate with the development of bladder cancer. Here we demonstrated that a patient that had persistent elevated BKV viruria (urine BKV DNA concentration more than 10(11) copies/ml) after renal transplantation. Then, bladder cancer was found in 13 months after kidney transplantation. The urine BKV DNA concentration was detected by real-time PCR and the BKV DNA in the bladder tumor was detected by PCR. BKV DNA was found in the marginal and central part of the bladder tumor. After removal of the bladder cancer, the urine BKV viral load in this patients dropped dramatically to <10(2) copies/ml. However, the urine viral load had increased modestly to 10(6) copies/ml in 3 months after surgery. Since there is a close correlation between the urine BK viral load and the presence of bladder cancer, we suggested that there might be a causal relationship between the reactivation of BKV and the development of bladder cancer in renal transplant patient.

  15. Immunosuppressive therapy induced coronary vasospasm and acute myocardial infarction in a patient undergoing new renal transplantation

    Akturk, Ibrahim Faruk; Yalcin, Ahmet Arif; Celik, Omer; Oner, Ender


    Immunosuppressant agents such as calcineurin inhibitors (CNI) used after solid organ transplantation may cause endothelial dysfunction, and coronary and renal arterial vasospasm. We report a patient presenting acute ST segment elevation myocardial infarction (STEMI) at the second week of renal transplantation. In the case of STEMI in patients with solid organ transplants under immunosuppressive therapy with CNI, coronary vasospasm associated with these drugs should be kept in mind before starting any interventional procedure. High dose nitroglycerine may immediately resolve tacrolimus or cyclosporine A induced coronary vasospasm. Calcium channel blockers should immediately be added to treatment because of the short half-life of nitroglycerine. PMID:26161107

  16. 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.

  17. Dengue fever in renal transplant patients: a systematic review of literature.

    Weerakkody, Ranga Migara; Patrick, Jean Ansbel; Sheriff, Mohammed Hussain Rezvi


    Dengue fever in renal transplanted patients has not been studied well, and we review all the literature about episodes dengue fever in renal transplant patients. The aim was to describe clinico-pathological characteristics, immunosuppressive protocols, need renal outcome and mortality. PubMed, LILACS, Google Scholar and Research Gate were searched for "Dengue" and "Renal/Kidney Transplantation" with no date limits. Hits were analyzed by two researchers separately. Fever, myalgia, arthralgia and headache was significantly lower than normal population, while pleural effusions and ascites were observed more. Incidence of severe dengue is significantly higher among transplant patients in this review, as well as they had a significantly higher mortality (8.9% vs 3.7%, p = 0.031). Age, period after transplantation and immunosuppressive profile had no effect on disease severity, mortality or graft out come. Presence of new bleeding complications and ascites was associated with more severe disease (p dengue fever in renal transplanted patients differ from the general population. Some degree of graft dysfunction is common during the illness, but only a minority develops graft failure.

  18. 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.

    Chaturaka Rodrigo


    Full Text Available This retrospective analytical study aimed at making a database of patients who underwent renal transplant from 31 December 2004 to 31 December 2006 under the Faculty of Medicine renal transplant program. The objective was to build a profile of renal transplant patients with focus on post KT infections and complications of renal transplants. An interviewer administered questionnaire was used. A total of 72 patients were studied; 18 (25% had died by February 2007. Forty-three patients (58.3% were interviewed in person, 17 were interviewed over the phone and 12 patients could not be contacted. Of those who were interviewed, 28 (38.9% were on azathioprine, prednisolone and cyclosporine, while 15 (20.8% were on predni-solone, cyclosporin and mycophenolate mofetil. Four patients had symptomatic cytomegalovirus infection and five had tuberculosis post transplant. Of all infections, the most commonly reported was urinary tract infection (11 cases. Thirty-three (45.8 % had received induction therapy with either basiliximab (n = 8 or daclizumab (n = 25. Acute rejection was the most commonly en-countered complication, with nine cases (12.5% being reported over the study period. Of late complications, most were due to immunosuppression. Overall, the 2-year survival was 75%. There was no significant difference between the centers of transplant.

    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

  2. Scintigraphic diagnosis of infectious complications in renal failure patients undergoing hemodialysis, continuous ambulatory peritoneal dialysis or renal transplant

    Ana María García Vicente


    Full Text Available Patients with end-stage renal disease have two therapeutic options, dialysis and renal transplantation. Infectious complications occurring in such patients will not only condition the effectiveness of such treatments, but are among the main causes of morbidity and mortality in such cases. Knowledge of the advantages and limitations of nuclear techniques is essential for management of these conditions.Pacientes em estágio final de doença renal têm duas opções terapêuticas, diálise e transplante renal. Complicações infecciosas que ocorrem em cada paciente são as principais causas de morbidade e mortalidade nestes casos. Conhecimentos das vantagens e limitações de técnicas nucleares são essenciais para o acompanhamento nestas condições.

  3. Outcomes of renal patients from the Ivory Coast transplanted abroad: time for a local kidney transplantation program.

    Ackoundou-N'Guessan, C; Gnionsahe, D A; Dekou, A H; Tia, W M; Guei, C M; Moudachirou, A M


    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.

  4. 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.

  7. 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.

    Full Text Available Aim. Evaluation of the possibility heart valve replacement in renal transplant recipients from a position of safe- ty for graft function. Materials and methods. 5 patients, heart valve replacement was performed with a func- tioning kidney transplant at a satisfactory its function. The average age of patients at the time of cardiac surgery was 38,8 ± 12,6 years, among whom were two (40% men and 3 (60% women. The interval between renal transplantation and heart surgery was 40,3 ± 44,1 (2 to 120 months. Prior to kidney transplantation, all patients were on renal replacement therapy with hemodialysis program for 50,2 ± 48,6 months. In 4 of the 5 patients of heart disease was the cause of infective endocarditis. Results. Average time IR was 81,2 ± 21,7 minutes , the average time of aortic clamping 63,6 ± 20,9 minutes and hypothermia during CPB 29,2 ± 3,2 °C. All patients were implanted with double-leaf mechanical prostheses "MedEng-2" and "SarboMedics". All 5 patients in sa- tisfactory condition were discharged from the hospital. The average duration of the postoperative period was 14,2 ± 3,4 days. All patients had relatively smooth flow after surgery, no infectious complications, a satisfactory renal transplant function and prosthetic heart valves. In the late period in four patients and transplant graft func- tion is satisfactory in terms of the observation of 5 years, 3 years and 6 months after surgery. Conclusion. Our experience shows the possibility of successful correction of heart defects in IR in renal transplant recipients. 

  9. Intralesional cidofovir in the treatment of cutaneous warts in a renal transplant patient.

    Blouin, Marie-Michèle; Cloutier, Richard; Noël, Réal


    Cutaneous warts are often recalcitrant to conventional therapy in immunocompromised patients. Cidofovir is a potent antiviral agent shown to have a broad spectrum of action against DNA virus, including human papillomavirus. To determine the efficacy of intralesional cidofovir in the treatment of florid warts in an immunocompromised renal transplant patient. The patient received seven injections of intralesional cidofovir at 4 week intervals in his numerous palmar warts. Based on our results, intralesional cidofovir is a promising therapeutic modality in the treatment of cutaneous warts in the renal transplant population.

  10. Reactivation of intestinal CMV in a renal transplant patient after 10 years from the transplant

    Maria Landi


    Full Text Available Introduction.We analyzed the clinical case of a 51 years old man, kidney transplanted on December 2002. On April 2011, he had acute rectal bleeding, renal chronic rejection (creatinine 2.9 mg/dl, Hgb 8.7 g/dl, positive anti-CMV antibodies (IgG. A colonoscopy showed diverticulosis of the rectum associated with deepithelialisation. The patient was treated with maintenance immunosuppressive post-transplant therapy. On June 2011, the colonoscopy showed a stenosing lesion of the sigmoid colon, and blood sampling and intestinal biopsy were performed to search Cytomegalovirus (CMV DNA by PCR. Methods. The presence of CMV-DNA was sought by automatic extractor QIACUBE, using QIAamp DNA BLOOD Mini Kit (Qiagen for whole blood and QIAamp DNA Mini Kit (Qiagen for biopsy.The extracted DNA was then amplified by Real Time PCR using Q-CMV RealTime Complete Kit (Nanogen, on instrument Applied Biosystems 7300. Results. At disease onset the viral load in whole blood was 208000 Geq/ml, and biopsy was positive. Antiviral therapy with Ganciclovir led to the negativity of the viral load and remission of symptoms. Conclusions. The clinical case described presented a reactivation of CMV infection in the intestine after more than 10 years from kidney transplantation, while the highest incidence of CMV reactivation usually occurs during the first year. In our opinion, the reactivation can be traced to long-term immunosuppressive therapy (maintenance posttransplant therapy in combination with a state of inflammation of the intestinal mucosa. In fact, patients with IBD treated with steroid drugs, in particular the group of refractory to therapy and thus have a recovery of the inflammatory process, are exposed to reactivation of CMV with intestinal localization.

  11. Serum Endocan Levels Associated with Hypertension and Loss of Renal Function in Pediatric Patients after Two Years from Renal Transplant

    de Souza, Livia Victorino; Oliveira, Vanessa; Laurindo, Aline Oliveira; Huarachı, DelmaRegına Gomes; Nogueira, Paulo Cesar Koch; Feltran, Luciana de Santis; Medina-Pestana, José Osmar


    Endocan is an important biomarker of inflammation and endothelial dysfunction that increases in association with several chronic diseases. Few published data have described the role of endocan in pediatric renal transplant (RT) patients. We evaluated the endocan concentrations in 62 children who underwent renal transplantation and assessed their relationships with the patients' blood pressure and loss of renal function. The endocan levels were significantly elevated in the pediatric RT patients who had hypertension and a loss of renal function. We determined positive correlations between the endocan concentrations and the hemodynamic variables (systolic blood pressure: r = 0.416; P = 0.001; pulse pressure: r = 0.412; P = 0.003). The endocan levels were inversely correlated with the estimated glomerular filtration rate (r = −0.388; P = 0.003). An endocan cutoff concentration of 7.0 ng/mL identified pediatric RT patients who had hypertension and a loss of renal function with 100% sensitivity and 75% specificity. In conclusion, the endocan concentrations were significantly elevated in pediatric RT patients who had both hypertension and a loss of renal function. The correlations between the endocan levels and the hemodynamic variables and the markers of renal function strengthen the hypothesis that it is an important marker of cardiorenal risk.

  12. Renalase Gene Polymorphism in Patients After Renal Allograft Transplantation

    Andrzej Pawlik


    Full Text Available Background/Aims: Renalase is a recently discovered protein, which is likely involved in regulation of blood pressure in humans and animals. Previous studies suggest that renalase reflects kidney functioning. A common missense polymorphism in the flavin-adenine dinucleotide-binding domain of human renalase (Glu37Asp has been described. In this study we examined the association between (Glu37Asp polymorphism (rs2296545 in renalase gene and kidney allograft function. Methods: The study enrolled 270 Caucasian kidney allograft recipients. SNP within the renalase was genotyped using TaqMan genotyping assays. Results: There were no statistically significant associations between renalase gene rs2296545 polymorphism and delayed graft function, acute rejection, chronic allograft dysfunction as well as creatinine serum concentrations and blood pressure values after transplantation. Conclusions: The results of this study suggest, that renalase gene rs2296545 polymorphism is not important factor determining renal allograft function.

  13. Antihypertensive treatment in renal transplant patients--is there a role for ACE inhibitors?

    Hausberg, M; Kosch, M; Hohage, H; Suwelack, B; Barenbrock, M; Kisters, K; Rahn, K H


    During the past two decades great progress was achieved with regards to short-term kidney graft survival. However, long-term graft survival did not improve similarly. Many factors contribute to chronic graft nephropathy eventually resulting in late graft loss, among these arterial hypertension is of major importance. In patients with chronic renal disease of diabetic and non-diabetic origin, angiotensin converting enzyme inhibitors have been convincingly shown to slow the progression of renal failure. The achieved nephroprotection correlates with the reduction of proteinuria by ACE inhibitor treatment. Also in renal transplant patients, ACE inhibitors have been shown unequivocally to reduce urinary protein excretion. The prevention of hyperfiltration, particular in the context of a reduced number of functional nephrons in patients with chronic graft nephropathy, could be important to prolong graft survival after renal transplantation. Moreover, ACE inhibitors may exert beneficial effects on immunologic processes contributing to chronic graft nephropathy. Many studies published in the last decade show convincingly that ACE inhibitors are safe and effective for the treatment of hypertension in renal allograft recipients. However, no data exist so far showing that ACE inhibitors are superior to other antihypertensive drugs in renal transplant patients and that they prolong graft survival. Studies investigating this issue are warranted. Apart from effects on the graft, ACE inhibitors may improve alterations of the cardiovascular system generally observed in renal transplant patients, such as structural alterations of large arteries, left ventricular hypertrophy, disturbed mechanical vessel wall properties and endothelial dysfunction. Therefore, angiotensin converting enzyme inhibitors could reduce cardiovascular morbidity and mortality in kidney transplant patients.

  14. Persistent mediastinal and axillary lymph node tuberculosis in a renal transplant patient with successful outcome.

    Oguz, Y; Yilmaz, M I; Eyileten, T; Caglar, K; Yenicesu, M; Kaya, A; Tasar, M; Saglam, M; Doganci, L; Gulec, B; Oner, K; Oktenli, C; Vural, A


    Tuberculosis is an opportunistic infection that carries substantial morbidity and mortality in renal transplant recipients. We report here about a 21 year-old man with a living related renal transplant from his mother who developed persistent extra-pulmonary tuberculosis. The disease showed aggressive invasion to the axillary and mediastinal regions with abscess formations, despite standard antituberculosis treatment. During the course of the disease, immunosuppressive therapy was stopped, and the patient received extraordinary doses of multiple antituberculosis drugs. The patient then showed an uneventful course with good clinical and radiological responses.

  15. Native kidney post-transplant lymphoproliferative disorder in a non-renal transplant patient.

    Araya, Carlos E; Mehta, Mansi B; González-Peralta, Regino P; Hunger, Stephen P; Dharnidharka, Vikas R


    PTLD is an important post-transplant complication. Although PTLD affects kidney allografts after renal transplantation, it has not been reported in native kidneys of other solid organ recipients. Herein, we report a child who underwent an orthotropic liver transplant for cryptogenic cholestatic hepatitis and developed fever, generalized lymphadenopathy, chronic EBV viremia, and lymphatic PTLD. Subsequently, she also developed gross hematuria and nephrotic range proteinuria. Kidney histology revealed EBV-positive mononuclear infiltrates within the renal parenchyma consistent with PTLD. Electron microscopy examination demonstrated subepithelial electron-dense deposits consistent with a membranous glomerulopathy pattern. The PTLD was successfully treated with reduced immunosuppression and cyclic cyclophosphamide, rituximab, and prednisone, but the renal disease progressed to end-stage renal failure within two yr. Repeat kidney histology showed chronic nephropathy and membranous glomerulopathy without PTLD infiltrates or detectable EBV staining, although chronic viremia persisted. To our knowledge, this is the first such child to be reported and highlights the importance of remaining vigilant for renal PTLD even in non-kidney organ recipients.

  16. 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.

  17. Usefulness of Doppler Parameter in Patients with Renal Transplantation

    Yoon, Yeo Chang; Shin, Byung Seok; Ohm, Joon Young; Ahn, Moon Sang [Chungnam National University Hospital, Daejeon (Korea, Republic of); Park, Mi Hyun [Dept. of Radiology, Dankook University Hospital, Cheonan (Korea, Republic of); Kim, Ho Jun [Dept. of Radiology, Konyang University Hospital, Daejeon (Korea, Republic of)


    The purpose of this study is to assess the usefulness of Doppler parameters in transplanted kidney function. Doppler parameters, including resistive index (RI), pulsatility index (PI), peak systolic velocity (PSV), and end diastolic velocity (EDV) were measured in the interlobar artery of 55 transplant recipients. Patients were grouped according to glomerular filtration rate (GFR): Group A (GFR < 30 ml / min / 1.73 m2, n = 27) and group B (GFR {>=}30 ml / min / 1.73 m2, n = 28). Doppler parameters were compared between groups and correlated with the GFR. GFR (40.1 {+-} 26.9) showed a significant negative correlation with RI (0.69{+-}.08) (p = .002, r = -.414). RI (0.72 vs. 0.67), PI (1.42 vs. 1.23), and EDV (10.5 vs. 15.3) differed significantly between groups (p < .05), however, PSV was not (36.9 vs. 47.1). Patients in group A (n = 11) with a lower RI than the mean had significantly lower PSV (31.7 vs. 45.1; p = .027) and EDV (11.1 vs. 16.7; p .017), compared with such patients in group B (n = 21). Doppler parameters are useful for evaluation of function of transplanted kidney. Even if the RI is normal, PSV and EDV may be used as hemodynamic indicators.

  18. Travel-related disseminated Penicillium marneffei infection in a renal transplant patient.

    Hart, J; Dyer, J R; Clark, B M; McLellan, D G; Perera, S; Ferrari, P


    Penicillium marneffei is a thermally dimorphic fungus that causes severe human immunodeficiency virus-related opportunistic infection in endemic areas of Southeast Asia and has rarely been reported in solid organ transplant (SOT) recipients. We report here the case of an Australian renal transplant patient who presented with disseminated P. marneffei infection shortly after a 10-day holiday to Vietnam, and review all previously published cases of penicilliosis associated with renal transplantation. This is the first reported case, to our knowledge, of P. marneffei infection in an SOT recipient acquired during travel to an endemic country, and highlights the importance of an accurate travel history when opportunistic infection is suspected, as well as giving appropriate health advice to transplant patients who travel.

  19. 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.

  1. 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.

  2. 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.

    Although sickle cell anemia and sickle cell disease produce a variety of functional renal abnormalities they uncommonly cause end stage renal failure. Renal transplantation has been a successful alternative for the treatment of the rare terminal chronic renal failure with outcomes comparable with non-sickle recipients. This approach, however, has not been often described on patients with renal failure associated with SC hemoglobinopathy. Here we report the outcomes of two patients with chroni...

    Full Text Available Tacrolimus (FK-506 is a part of most immunosuppressive protocols after kidney transplantation because it significantly affects the survival of transplanted organs in post - transplantation period. FK-506 is characterized by a narrow therapeutic index and large interindividual variability in pharmacokinetics. Partly, these variations can be explained by 6986A>G polymorphism CYP3A5 gene. As a substrate for CYP3A5 isoenzyme, FK–506 has a different elimination rate amnog individuals, which is caused by CYP3A5 gene polymorphism. The primary objective of this study was to investigate the frequency of CYP3A5 gene polymorphism (6986A>G in kidney transplant patients and comparison with the healthy volunteers. The second objective of this study was to determine the influence of the investigated polymorphism on FK–506 dosage regimen one month after kidney transplantation.Pharmacogenetic retrospective study included 121 examinees - 60 patients with renal transplant and 60 healthy volunteers. Patients have routine determination of drug concentration at the Clinic of Nephrology, Clinical Center Niš, Serbia. PCR method (Ashavaid TF et al. was used to determine the polymorphism of CYP3A5 gene. Our study did not show statistically significant differences in allele (p=0.616 and genotype (p=0.602 frequencies between the studied polymorphism in renal transplant patients and healthy volunteers. A statistically significant difference was found between patients with different genotypes of CYP3A5 regarding dose (p=0.001, weight adjusted dose (p=0.005, and dose normalized level of FK–506 (p=0.039 one month after transplantation. Patients with kidney transplant and healthy subjects in Serbian population did not show difference in the frequency of alleles of CYP3A5 gene. CYP3A5 gene polymorphism affects the dose regimen of tacrolimus one month after kidney transplantation. Acta Medica Medianae 2013;52(1:33-38.

    Noonan syndrome is a congenital, common, hereditary disorder. Facial dysmorphism, growth retardation, and various heart defects are typical clinical features. In patients with minor cardiac pathology, life expectancy is normal. We report a case of renal transplant in a pediatric patient with Noonan syndrome that ended with death of the patient. Our patient presented with unexpected and refractory postoperative neurological complications that were unresponsive to intensive therapy, and the patient died because of secondary complications.

    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.

  11. Comparative study of impact of hemodialysis and renal transplantation on cognitive functions in ESRD patients.

    Anwar, Waleed; Ezzat, Haitham; Mohab, Amr


    Cognitive impairment is defined as a newly appeared deficit in at least two areas of cognitive functions, including disturbances in memory, executive functioning, attention or speed of information processing, perceptual motor abilities, or language. Cognitive impairment is highly prevalent in ESRD patients when compared with the general population. It has also been associated with a decreased quality of life. Cognitive functions in patients with ESRD showed improvement with dialysis and renal transplantation. These findings illustrate the potential importance of evaluating and comparing the effects of hemodialysis and transplantation regarding cognitive performance and thus quality of life in ESRD patients and normal subjects. This study was carried out in 100 patients (50 ESRD patients on regular hemodialysis for at least 6 months and 50 post-transplant patients who had maintained successful kidney graft for at least 3 months). All patients underwent laboratory and psychometric scoring tests, including trail making test part A, trail making test part B, digit span, and mini-mental state examination. Thirty healthy adults matched by age and sex served as a control group. The results showed significant differences in cognitive function tests results between transplant and hemodialysis patients (P0.05). Renal transplantation as a modality of treatment, in ESRD patients, is superior to hemodialysis in terms of cognitive performance improvement. Copyright © 2015 Sociedad Española de Nefrología.

    Chavlovski A


    Full Text Available Anna Chavlovski,1 Greg A Knoll,1–3 Timothy Ramsay,4 Swapnil Hiremath,1–3 Deborah L Zimmerman1–31University of Ottawa, 2Ottawa Hospital, 3Kidney Research Centre, Ottawa Hospital Research Institute, 4Ottawa Methods Centre, Ottawa, ON, CanadaBackground: In patients with end-stage renal disease, use of vitamin D and calcium-based phosphate binders have been associated with progression of vascular calcification that might have an impact on renal transplant candidacy. Our objective was to examine management of mineral metabolism in patients wait-listed for renal transplant and to determine the impact on cardiac perfusion imaging.Methods: Data was collected retrospectively on patients wait-listed for a renal transplant (n = 105, being either active (n = 73 and on hold (n = 32. Demographic data, medications, serum concentrations of calcium, phosphate, parathyroid hormone, and cardiac perfusion imaging studies were collected from the electronic health record. Chi-square and Student’s t-tests were used to compare active and on-hold patients as appropriate. Logistic regression was used to examine variables associated with worsening cardiac imaging studies.Results: The wait-listed patients were of mean age 56 ± 14 years and had been on dialysis for 1329 ± 867 days. On-hold patients had received a significantly greater total dose of calcium (2.35 ± .94 kg versus 1.49 ± 1.52 kg; P = 0.02 and were more likely to have developed worsening cardiovascular imaging studies (P = 0.03. Total doses of calcium and calcitriol were associated with worsening cardiovascular imaging studies (P = 0.05.Conclusion: Patients on hold on the renal transplant waiting list received higher total doses of calcium. A higher total dose of calcium and calcitriol was also associated with worsening cardiovascular imaging. Time on dialysis before transplant has been associated with worse post-transplant outcomes, and it is possible that the total calcium and calcitriol dose

  13. Renal cell carcinoma co-existent with other renal disease: clinico-pathological features in pre-dialysis patients and those receiving dialysis or renal transplantation.

    Peces, Ramón; Martínez-Ara, Jorge; Miguel, José Luis; Arrieta, Javier; Costero, Olga; Górriz, José Luis; Picazo, Mari-Luz; Fresno, Manuel


    Patients on chronic dialysis are prone to developing acquired cystic kidney disease (ACKD), which may lead to the development of renal cell carcinoma (RCC). The risk factors for the development of RCC so far have not been determined in pre-dialysis patients with co-existent renal disease. The aim of this study was to evaluate the clinico-pathological features of RCC in pre-dialysis patients with associated renal diseases or in those undergoing chronic dialysis and renal transplantation. We studied 32 kidneys from 31 patients with RCC and associated renal diseases. Of those, 18 kidneys were from 17 patients not on renal replacement therapy (RRT) when diagnosed with RCC; 14 patients received dialysis or dialysis followed by renal transplantation. Several clinico-pathological features were analysed and compared between the two groups. Overall, there was a preponderance of males (75%); nephrosclerosis was the predominant co-existent disease (31%). The median intervals from renal disease to RCC in the dialysis and transplanted groups were significantly longer than in the pre-dialysis group (15.8+/-1.1 vs 2.4+/-0.7 years, P<0.0001). In contrast to pre-dialysis RCC, the dialysis and transplant RCC groups had greater frequency of ACKD (100 vs 28%, P<0.0001), papillary type RCC (43 vs 11%, P<0.05) and multifocal tumours (43 vs 5%, P<0.05). At the end of the study, 71% of dialysis and transplanted patients and 72% of pre-dialysis patients were alive. ACKD develops in dialysis patients, as it does in those with renal disease prior to RRT. The duration of renal disease, rather than the dialysis procedure itself, appears to be the main determinant of ACKD and RCC. The RCC occurring in patients with ACKD and prolonged RRT is more frequently of the papillary type and multifocal than the RCC occurring in patients with no or few acquired cysts and a short history of renal disease. Long-term outcomes did not differ between the two groups.

This review aims to provide an overview of our experience of imaging children with chronic renal failure and transplants. (orig.)

  15. Aminoaciduria as a marker of acute renal transplant rejection--a patient study.

    Macpherson, N A; Moscarello, M A; Goldberg, D M; Ish-Shalom, N; Arbus, G S


    Over 12 months, urine samples were systematically collected from 40 children who underwent renal transplantation for the treatment of end-stage renal disease. Sequential determinations of the excretion of individual amino acids relative to that of creatinine were carried out on 15 subjects. Nine of these (including three who sustained episodes of acute rejection) retained a native kidney in-situ, while in six patients (including three who underwent an episode of acute rejection) both native kidneys had been removed. In both subgroups, the amino acid/creatinine ratios of early morning urine samples were higher shortly before clinical manifestations of acute rejection became evident than in patients who, following renal transplantation, had stable kidney function, chronic graft rejection, or acute tubular necrosis, with one exception: a patient with one native kidney in-situ in whom acute tubular necrosis developed immediately after transplantation. The amino acids showing the greatest increase included Thr, Ser, Gly, and Ala. These values fell dramatically immediately prior to the clinical episode of acute rejection, with Thr, Ala, and Phe showing the most consistent changes. These alterations in urinary amino acid excretion occurred several days before changes in urinary protein excretion or the serum concentrations of urea and creatinine, and may have a role to play in the monitoring of renal transplant recipients.

  16. 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.

  17. 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.

  18. Outcomes of renal transplantation in patients with immunoglobulin A nephropathy in India

    Chacko B


    Full Text Available Background: There is a paucity of data on the course of renal transplant in patients with immunoglobulin A (IgA nephropathy (IgAN from India. While the natural history of IgAN in the Indian context is rapidly progressive, the post-transplant course remains speculative. Aim: To study the graft survival in renal transplant recipients whose native kidney disease was IgAN and the incidence and correlates of recurrent disease. Settings and Designs: Retrospective case control study from a Nephrology unit of a large tertiary care center. Materials and Methods: The outcomes of 56 transplant patients (58 grafts with biopsy-proven IgAN and of 116 patients without IgAN or diabetic nephropathy, transplanted during the same period were analyzed. Correlates of biopsy-confirmed recurrent disease were determined. Statistical Analysis: Means were analyzed by Student′s t test and Mann-Whitney test; proportions were determined by Chi-square analysis and graft survival curves were generated using the Kaplan-Meier. Results: Five-year graft survival for IgA patients was not significantly different from that in the reference group (90% and 79%, P = 0.6. During a mean follow-up of 42 months (range, 1-144, 28 event graft biopsies were required in 20 grafts of IgAN. Histological recurrence was diagnosed in five of the 20 available biopsies (25% after a mean duration of 28 months. Recurrence did not correlate with donor status, HLA B35 and A2, recipient age, gender or immunosuppression. Conclusions: Renal transplantation is an appropriate treatment modality for IgA nephropathy patients with end-stage renal disease in India, despite the potential for recurrent disease. The posttransplant course is an indolent one when compared to the malignant pretransplant phase.

  19. Experience of percutaneous access under ultrasound guidance in renal transplant patients with allograft lithiasis

    Silvano Palazzo


    Full Text Available Objective: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. Material and methods: Here we report our experience in two cadaveric transplant patients with urolithiasis. The first case was a patient of 68 years with a 20 mm stone located in the transplanted kidney pelvis and another smaller in a lower calyx. The second case was a patient of 65 years with a 15 mm stone in the distal part of the transplanted ureter. In both cases the patients were asymptomatic, but they had a reduction in urine output associated with worsening of the transplanted kidney function. The diagnosis was performed in both cases with ultrasound study, showing a severe hydronephrosis and it was confirmed by computed tomography scan. In both cases, we performed a Percutaneous Nephrolithotomy (PCNL. Access was made after targeting the stone, through a lower pole puncture under ultrasound guidance. The first case was treated with pneumatic and laser energy, breaking stones through a nephroscope. In the second case we performed a laser lithotripsy of the ureteral stone, using a flexible videoureteroscope. At the end of both procedures a Double-J stent and a 14 Fr Malecot nephrostomy were positioned, that were removed at 6 weeks and 10 days, respectively. Results: Both patients achieved a resolution of the worsening of renal function, recovering the spontaneous diuresis. The surgical procedure using ultrasound guidance was safe and allowed quick access to the renal pelvis. Both patients experienced no bleeding or infection during hospitalization. Conclusions

  20. [Liver damage caused by atorvastatin and cyclosporine in patients with renal transplant].

    Ivandić, Ema; Bašić-Jukić, Nikolina


    Kidney transplantation is the preferred method of treatment of end-stage renal disease, which significantly improves the quality of life, but also increases survival when compared to dialysis. Prevention of acute or chronic rejection demands the use of immunosuppression. However, nephrotoxicity, hepatotoxicity, cardiovascular disease, post-transplantation diabetes mellitus, chronic graft dysfunction and dyslipidemia may all occur as complications of immunosuppressive therapy. Dyslipidemia is a significant problem in renal transplant recipients due to the fact that it increases the risk of cardiovascular mortality in patients in whom the risk is already higher than in the general population. Very often, there is an interaction between immunosuppressive drugs, especially cyclosporine, and drugs that are used in the treatment of dyslipidemia. We present a case of a patient who developed severe hepatotoxicity after the introduction of atorvastatin in a cyclosporine-based immunosuppressive regimen. After discontinuation of atorvastatin and replacement of cyclosporine with everolimus, liver chemistries returned to normal values.

  1. Successful Renal Transplantation in a Patient with Behcet Disease and Hodgkin Lymphoma in Remission

    Vural Taner YILMAZ


    Full Text Available Behcet's disease (BD is an inflammatory multisystemic disease characterized by perivascular inflammation and generally presents with recurrent oral and genital ulcers and uveitis. It is known that BD may also involve the kidneys. Amyloidosis, glomerulonephritis (crescentic, proliferative, IgA nephropathy, interstitial nephritis are commonly described renal lesions which may lead to end-stage renal disease (ESRD in BD. Immunosuppressive therapies used for the treatment of BD may cause malignant diseases (lymphoma, skin and solid organ malignancies, etc. The risk with azathioprin is especially high after 10 years of treatment. Cyclosporine, another immunosuppressive agent frequently used for treatment of BD, also has tumorigenic potential and is associated with renal toxicity and renal failure. Renal transplantation may be performed in patients with malignancies after a 2-5 year complete remission period, although it may differ according to the type of tumor. We report a case of end-stage renal disease and Hodgkin's lymphoma occurring after treatment with immunosuppressive medicine for BD. The patient was successfully treated with renal transplantation.

  2. 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.

  3. 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.

  4. MAG3 diuresis renography and output efficiency measurement in renal transplant patients

    Spicer, T.; Gruenewald, S.; Chi, K.K.; Larcos, G.; Farlow, D.; Choong, K.; Chapman, J. [Westmead Hospital, Weastmead, NSW, (Australia). Department of Nuclear Medicine and Ultrasound


    Full text: Urinary tract obstruction following renal transplantation often presents a diagnostic dilemma, as some patients with equivocal investigations subsequently show improvement following stenting. The purposes of this study were to (1) establish a normal range of renal output efficiency (ROE) in transplants, and (2) assess the usefulness of MAG3 diuresis renography and ROE in suspected allograft obstruction. Twenty-two renal transplant patients with stable function and no evidence of hydronephrosis on serial ultrasound had a diuretic MAG3 scan with calculation of ROE. Three patients with proven graft obstruction underwent the same scanning procedure. Methodology was as follows: (1) 60 MBq of {sup 99m}Tc-DTPA GFR was performed (single injection-dual blood sample method); (2) patients were then prehydrated with either oral or IV fluid; (3) 10 min prior to scanning, intravenous Frusemide 20-80 mg (dose depending on renal function) was injected, and then (4) 200 MBq of MAG3 for a 20 min scan. The studies were then qualitatively and quantitatively reviewed to assess uptake and excretion, and the ROE was calculated. The mean ROE for the twenty-two normal renal transplant patients was 85.7% {+-} 4.1% (range 78 - 90%). Technetium-99m-DTPA GFR was 55.5 mL/min/1.73m{sup 2} (range 27 to 83). The MAG3 scans in the three obstructed patients were equivocal for obstruction but the ROE values of 59%, 68% and 75% were more than 2.5 standard deviations below our calculated normal mean. The {sup 99m}Tc-DTPA GFRs were 61,17 and 57 mL/min/1.73m{sup 2}, respectively. Thus, in normal grafts the ROE should exceed 78 per cent. Our data suggest that ROE may be a useful addition to standard scintigraphic parameters in diagnosis of graft obstruction.

  5. Increased urinary angiotensin-converting enzyme 2 in renal transplant patients with diabetes.

    Fengxia Xiao

    Full Text Available Angiotensin-converting enzyme 2 (ACE2 is expressed in the kidney and may be a renoprotective enzyme, since it converts angiotensin (Ang II to Ang-(1-7. ACE2 has been detected in urine from patients with chronic kidney disease. We measured urinary ACE2 activity and protein levels in renal transplant patients (age 54 yrs, 65% male, 38% diabetes, n = 100 and healthy controls (age 45 yrs, 26% male, n = 50, and determined factors associated with elevated urinary ACE2 in the patients. Urine from transplant subjects was also assayed for ACE mRNA and protein. No subjects were taking inhibitors of the renin-angiotensin system. Urinary ACE2 levels were significantly higher in transplant patients compared to controls (p = 0.003 for ACE2 activity, and p≤0.001 for ACE2 protein by ELISA or western analysis. Transplant patients with diabetes mellitus had significantly increased urinary ACE2 activity and protein levels compared to non-diabetics (p<0.001, while ACE2 mRNA levels did not differ. Urinary ACE activity and protein were significantly increased in diabetic transplant subjects, while ACE mRNA levels did not differ from non-diabetic subjects. After adjusting for confounding variables, diabetes was significantly associated with urinary ACE2 activity (p = 0.003 and protein levels (p<0.001, while female gender was associated with urinary mRNA levels for both ACE2 and ACE. These data indicate that urinary ACE2 is increased in renal transplant recipients with diabetes, possibly due to increased shedding from tubular cells. Urinary ACE2 could be a marker of renal renin-angiotensin system activation in these patients.

  6. Clinical value of ambulatory blood pressure in pediatric patients after renal transplantation.

    Krmar, Rafael T; Ferraris, Jorge R


    Hypertension is a highly prevalent co-morbidity in pediatric kidney transplant recipients. Undertreated hypertension is associated with cardiovascular complications and negatively impacts renal graft survival. Thus, the accurate measurement of blood pressure is of the utmost importance for the correct diagnosis and subsequent management of post-renal transplant hypertension. Data derived from the general population, and to a lesser extent from the pediatric population, indicates that ambulatory blood pressure monitoring (ABPM) is superior to blood pressure measurements taken in the clinical setting for the evaluation of true mean blood pressure, identification of patients requiring antihypertensive treatment, and in the prediction of cardiovascular outcome. This Educational Review will discuss the clinical value of ABPM in the identification of individual blood pressure phenotypes, i.e., normotension, new-onset hypertension, white-coat hypertension, masked hypertension, controlled blood pressure, and undertreated/uncontrolled hypertension in pediatric kidney transplant recipients. Finally, we examine the utility of performing repeated ABPM for treatment monitoring of post-renal transplant hypertension and on surrogate markers related to relevant clinical cardiovascular outcomes. Taken together, our review highlights the clinical value of the routine use of ABPM as a tool for identifying and monitoring hypertension in pediatric kidney transplant recipients.

  7. Applying best practices to designing patient education for patients with end-stage renal disease pursuing kidney transplant.

    Skelton, Stacy L; Waterman, Amy D; Davis, LaShara A; Peipert, John D; Fish, Anne F


    Despite the known benefits of kidney transplant, less than 30% of the 615 000 patients living with end-stage renal disease (ESRD) in the United States have received a transplant. More than 100 000 people are presently on the transplant waiting list. Although the shortage of kidneys for transplant remains a critical factor in explaining lower transplant rates, another important and modifiable factor is patients' lack of comprehensive education about transplant. The purpose of this article is to provide an overview of known best practices from the broader literature that can be used as an evidence base to design improved education for ESRD patients pursuing a kidney transplant. Best practices in chronic disease education generally reveal that education that is individually tailored, understandable for patients with low health literacy, and culturally competent is most beneficial. Effective education helps patients navigate the complex health care process successfully. Recommendations for how to incorporate these best practices into transplant education design are described. Providing more ESRD patients with transplant education that encompasses these best practices may improve their ability to make informed health care decisions and increase the numbers of patients interested in pursuing transplant.

  8. Use of non-irradiated blood components in Campath (alemtuzumab)-treated renal transplant patients.

    Hui, Y M T; Regan, F; Willecombe, M; Taube, D


    The prevention of transfusion-associated graft-versus-host disease (TA-GvHD) through the irradiation of components is key as there is no effective treatment. Universal leucodepletion reduces but may not eliminate TA-GvHD; therefore, irradiation is still recommended. In 2010, Campath (alemtuzumab) was added as an indication for irradiation but was not implemented everywhere. To identify any cases of TA-GvHD in our Campath-conditioned renal transplant patients, who were transfused with non-irradiated components. Retrospective study of Campath-conditioned renal transplant patients transfused with non-irradiated components. In those transfused up to 9 months following Campath who survived to 1-year follow-up, TA-GvHD was excluded. For patients not followed-up for a full year, we reviewed medical records for features of TA-GvHD. For patients transfused after 9 months following Campath, survival of at least 3 months following last transfusion excluded TA-GvHD. Six hundred and forty-seven Campath-conditioned renal transplant patients were transfused; 616 were transfused within 9 months following Campath; 601 were alive at 1 year, excluding TA-GvHD. Twelve died and three were not followed-up for a full year, but a review of medical records excluded TA-GvHD. The 31 patients transfused 9 months or longer following Campath were all alive 6 months following the last transfusion, excluding TA-GvHD. Despite receiving non-irradiated components, none of the 647 Campath-conditioned renal transplant patients developed TA-GvHD. Further reviews to replicate our data could enable change to guidance, at least in UK where components are leucodepleted, as an unnecessary requirement for irradiated components has both clinical delay and cost implications. © 2016 British Blood Transfusion Society.

  9. Quality of life in a cohort of patients diagnosed with renal failure in childhood and who received renal transplant.

    Tozzi, Alberto E; Mazzotti, Eva; Di Ciommo, Vincenzo Maria; Dello Strologo, Luca; Cuttini, Marina


    Studies on HRQOL on kidney-transplanted young adults who had a diagnosis of chronic renal failure (CRF) in the pediatric age are uncommon. We studied HRQOL and its predictors in a sample of young adults with CRF in childhood who underwent a renal transplant. We recruited patients ≥18 yr old with renal transplant. We measured HRQOL by a standardized questionnaire on lifestyle, Short Form-36 (SF-36; including a PCS and a MCS; scale: 0-100), the GHQ (for short-term changes in mental health; scale: 0-36), and the MSPSS (with scales for family, friends, and significant others; scale: 0-100). We assessed the association of potential predictors of HRQOL through multiple linear regression models. We studied 66 patients aged 18-34 yr. The average PCS score was 76.4, and the average MCS score was 73.9. The mean GHQ total score was 14.8, and the total scale MSPSS mean score was 70. Severe comorbidities significantly affected the PCS score. Individuals with severe comorbidities had lower PCS scores.

  10. Unforeseen Intra-operative Hyperkalemia in a well Dialyzed Patient during Renal Transplantation

    Gautam P


    Full Text Available Renal excretion and cellular uptake of potassium play key roles in the body′s defense mechanism against hyperkalemia. Intra-operative hyperkalemia is an uncommon life-threatening complication during elective renal transplant surgery. We report herewith a non-insulin dependent diabetic kidney transplant recipient with prolonged pre-operative fasting, in whom, despite pre-operative hemodialysis, unforeseen high serum potassium level suddenly presented as wide-complex bradycardia during the surgery. The patient responded well to medical therapy of the hyperkalemia and the surgery was completed uneventfully. It is difficult to single out the exact cause of hyperkalemia in our patient. Prolonged pre-operative fasting for about nine hours, associated with insulinopenia and hyperglycemia, in the presence of β-blockade and metabolic acidosis, have probably collectively resulted in efflux of potassium from intra-cellular stores. This potentially catastrophic complication should be remembered in diabetic patients undergoing any type of surgery.

  11. 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.

  12. 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.

  13. Effect of active infection on cytochrome P450-mediated metabolism of cyclosporine in renal transplant patients.

    Hegazy, S K; Adam, A G; Hamdy, N A; Khalafallah, N M


    Infections downregulate cytochrome-P activities and thus may alter drug disposition, especially for drugs with a narrow therapeutic index. Cyclosporine (CyA), still used for the prevention of allograft rejection in renal transplant recipients in Egypt, seems to be affected by these infectious changes, based on random clinical observations. In the present study, the effects of bacterial and fungal infection on CyA metabolism were studied in renal transplant patients and subsequent nephrotoxicity was monitored. Twenty renal transplant patients, diagnosed with fungal or bacterial infection, were recruited from the renal transplantation outpatient clinic in Alexandria University Hospitals. No dose adjustment in CyA was performed at least 1 week before the onset of infection. Exclusion criteria were patients with acute or chronic unstable liver disease, elderly patients, and patients on concomitant drugs affecting CyA metabolism. CyA trough levels and serum creatinine (SCR) concentrations were measured by fluorescence polarization immunoassay and enzymatic assay, respectively, pre-infection, during infection and in many cases, post infection. CyA trough levels and SCR concentrations increased significantly during the infection (P < 0.001, P = 0.002) respectively. Of the patients, 87% experienced a concomitant rise in CyA trough level and SCR concentrations. No significant difference between pre-infection and post-infection levels of CyA trough and SCR was found. CyA trough and SCR levels increased during bacterial and fungal infections and returned to pre-infection levels once the infection was resolved. The data generated stress the importance of monitoring CyA levels during episodes of infection. Our recommendations concerning CyA dose adjustment differ according to severity and duration of infection. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    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)

  15. Metastatic renal cell carcinoma from a native kidney of a renal transplant patient diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA biopsy

    Yaseen Alastal


    Full Text Available Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA biopsy sampling of enlarged lymph nodes is increasingly used to diagnose metastatic tumors, especially of the gastrointestinal tract and the lungs. Herein, we describe the diagnosis of metastatic renal cell carcinoma from a native kidney of a 54 year-old male patient, who had a 5-years history of renal transplant, by EUS-FNA of mediastinal and celiac lymph nodes. Histological and immunohistochemical findings confirmed the origin of metastatic tumor. EUS-FNA with proper cytological evaluation can be useful in the diagnosis of metastatic renal cell carcinoma in renal transplant patients

  18. 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.

  19. Long-term follow-up of kidney allografts in patients with sickle cell hemoglobinopathy Transplante renal na anemia falciforme

    João R. Friedrisch


    Full Text Available Although sickle cell anemia and sickle cell disease produce a variety of functional renal abnormalities they uncommonly cause end stage renal failure. Renal transplantation has been a successful alternative for the treatment of the rare terminal chronic renal failure with outcomes comparable with non-sickle recipients. This approach, however, has not been often described on patients with renal failure associated with SC hemoglobinopathy. Here we report the outcomes of two patients with chronic renal failure due to SC hemoglobinopathies who underwent renal transplantation. At the time of the transplantation they were both severely anemic and had frequent vasoocclosive pain crises. Both patients evolved with good allograft function, near normal hematological parameters, and very rare pain crisis, thirteen and eight years after transplant. These cases illustrate that terminal renal failure due to SC hemoglobinopathy can be successfully managed by renal transplantation and satisfactory long-term results are achievable not only in terms of renal allograft function but also of their hematological condition.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 foram submetidos ao transplante renal. No momento do transplante ambos apresentavam severa anemia e crises dolorosas freqüentes. Os pacientes evoluíram com boa função do enxerto, parâmetros hematológicos quase normais e praticamente assintomáticos do ponto de vista da hemoglobinopatia, treze e oito anos após o transplante. Estes casos ilustram

    McGrogan, D; David, M D; Roberts, C; Borman, A M; Nath, J; Inston, N G; Mellor, S


    Eumycetoma is an unusual infection in immunocompromised patients outside the tropics, caused by a variety of fungal pathogens. We describe the case of a 51-year-old renal transplant recipient who presented with a large pseudotumoral foot lesion necessitating complete surgical excision of the lesion. Cultures and molecular diagnosis confirmed Phaeoacremonium fuscum. This is the first case, to our knowledge, of fungating mycetoma caused by this fungal species in a solid organ transplant recipient. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  1. Fatal lactic acidosis possibly related to ganciclovir therapy in a renal transplant patient?

    Wittebole, Xavier; Morelle, Johann; Vincent, Marie-Françoise; Hantson, Philippe


    Ganciclovir is widely prescribed in renal transplant patients for the prevention or treatment of herpes and cytomegalovirus (CMV) infections. Side-effects are usually represented by hematological disorders, and particularly leucopenia. We report a case of severe and fatal lactic acidosis developing in a 76-year-old renal transplant woman, a few days after ganciclovir has been introduced to treat CMV pneumonia. Usual etiologies of lactic acidosis were ruled out. A high lactate/pyruvate molecular ratio was suggestive of a respiratory chain dysfunction. With the analogy to nucleoside analogues-related lactic acidosis, we suggest that ganciclovir may exceptionally be responsible for respiratory chain dysfunction and subsequent lactic acidosis, and we discuss potential risk factors in our patient.

  2. Limitations of indium-111 leukocyte scanning in febrile renal transplant patients

    Sebrechts, C.; Biberstein, M.; Klein, J.L.; Witztum, K.F.


    Indium-111-labeled leukocyte scanning was evaluated as a technique for investigating possible abscess as the cause of fever in 10 renal allograft recipients under therapy for rejection, acute tubular necrosis, or urinary infection. The usefulness of the method in this setting was found to be limited by marked nonspecificity of renal, pulmonary, and other focal leukocyte accumulation. Although wound infections were correctly identified, false-positive scans resulted in multiple nonproductive consultations and radiologic procedures (some invasive) and contributed to the decision to perform one negative exploratory laparotomy. Such generalized nonspecificity in this patient population is in distinct contrast to the experience with this diagnostic test in nontransplant patients, and has not previously been reported. Possible explanations and implications of these findings are discussed. Consequently, great caution is recommended in the use of indium-111 leukocyte scans to diagnose infection in febrile renal transplant patients who present in a similar clinical setting.

  3. [Drug utilization in renal transplant patients: medication practices and representations].

    de Arruda, Guilherme Oliveira; Renovato, Rogério Dias


    Qualitative research approach, descriptive and exploratory with objective of to know the practices and representations of medication on the use of drugs by people transplanted kidney. 18 people participated in the Dourados (MS), through semistructured interview. The theoretical contributions of medication practices were Peter Conrad and representation of Stuart Hall. The definition of the categories of theoretical analysis was Michel Foucault. Respondents had a mean age of 53.5 years, 13 males and 5 females, with median time to transplant eight years. The medications predominantly used were immunosuppresssive. We developed three categories of analysis: the drug as part of everyday life, the central role of the drug and correlation with rejection, and medicine and the autonomy of the transplanted kidney. The drugs are part of everyday life and the representations of autonomy and quality enhance your daily use.

  4. Factors influencing patient and graft survival in 300 cadaveric pediatric renal transplants.

    Churchill, B M; Sheldon, C A; McLorie, G A; Arbus, G S


    We reviewed the results of 300 cadaveric pediatric renal transplantations performed at our institution. The procedures provided significant survival and improvement of the quality of life in the majority of children. Recipient and graft survival was better in patients more than 5 years old than in younger children. Early nontechnical thrombosis was a major specific problem in young recipients. The original disease did affect graft survival. Uncorrected congenital bladder storage and micturition inefficiency adversely affected graft survival.

    Mosconi, G; Panicali, L; Persici, E; Conte, D; Cappuccilli, M L; Cuna, V; Capelli, I; Todeschini, P; D'Arcangelo, G Liviano; Stefoni, S


    Kidney transplantations combined with other solid organs are progressively increasing in number. There are no guidelines regarding the nephrologic indications for combined transplantations, namely liver-kidney (LKT), or heart-kidney (HKT), in preemptive patients with chronic kidney failure who are not on regular dialysis therapy. The objective of this study was to assess the functional contribution of the native kidneys after preemptive kidney transplantation combined with other solid organs. From 2004, 9 patients (aged 50.3 +/- 8.5 years) with chronic kidney failure (creatinine 2.5 +/- 1.0 mg/dL) caused by polycystic kidney disease (n = 4), vascular nephropathy (n = 2), interstitial nephropathy (n = 1), glomerulonephritis (n = 1), or end-stage kidney disease (n = 1), underwent combined transplantations (8 LKT, 1 HKT). A scintigraphic functional study (Tc-99DMSA or Tc-99mMAG3), was performed at 4 +/- 3 months after transplantation to evaluate the functional contribution of both the native kidneys and the graft. All patients were given immunosuppressive drugs, including a calcineurin inhibitor (tacrolimus/or cyclosporine). At the time of scintigraphy, renal function in all patients was 1.3 +/- 0.3 mg/dL. The functional contribution of the transplanted kidneys was on average 77 +/- 18%. Only in 1 patient was the contribution of the graft organic nephropathy. In light of our experience, a creatinine clearance transplantation. Close clinical and instrumental assessment pretransplant is essential before proceeding with a combined transplant program to exclude functional forms and to optimize the use of organs.

    Riva, Natalia; Guido, Paulo Caceres; Ibañez, Juan; Licciardone, Nieves; Rousseau, Marcela; Mato, Gabriel; Monteverde, Marta; Schaiquevich, Paula


    Cyclosporin is a calcineurin inhibitor widely used in renal transplant patients to prevent organ rejection. Several position papers have been published but no reports on the practical experience in pediatric patients undergoing conversion between cyclosporin innovator and generic products are available. To evaluate the pharmacokinetics and safety as part of therapeutic monitoring of cyclosporin in renal transplant pediatric patients who switch from the innovator to the generic formulation in Argentina. Hospital de Pediatría JP Garrahan, Buenos Aires, Argentina. Stable pediatric renal transplant patients (6 months post-transplant) switched from the innovator to the generic formulation of cyclosporin microemulsion capsule. Cyclosporin pharmacokinetic parameters were obtained while taking the innovator and after starting with the generic formulation. Blood samples were drawn before and 1, 2, and 3 h after drug administration and subsequently quantified. Pharmacokinetic parameters were obtained by means of a Bayesian approach. Cyclosporin pharmacokinetic parameters (area under the curve, AUC; Blood concentration after 2 h, C2), adverse events and graft rejection. A total of 12 patients were included. Median (range) age and time post-transplant were 10.7 years (6.5-17.7) and 8.3 years (3.4-14.0), respectively. Two patients or their parents did not consent to the switch. Median (range) dose normalized cyclosporin AUC and C2 were 1.15 (mg*h/L)/mg/kg (0.72-3.0) and 265.5 (ng/ml)/mg/kg (120.8-725.7), respectively, on the innovator therapy and 1.05 (mg*h/L)/mg/kg (0.54-2.22) and 317.1 (ng/ml)/mg/kg (116.7-564.7) for the generic drug after the switch. The median (range) percentage of change in the AUC and C2 when switching between formulations were 16.7 % (0.7-56.7) and 13.1 % (3.7-68.6), respectively. No significant changes in serum creatinine levels were registered when comparing before and after substitution of products. Adverse events (number of events) recorded 5 months

  7. 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

  8. 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.

  9. Active video gaming in patients with renal transplant: a pilot study.

    Wang, Dorothy Wei Yun; Sills, Laura L; MacDonald, Sara B; Maianski, Ziv; Alwayn, Ian


    Patients with renal transplant are at higher risk of mortality from cardiovascular disease (CVD) compared with the general population. Physical activity has been shown to reduce the risk of CVD mortality in these patients. Unfortunately, barriers such as the harsh Canadian climate prevent patients from engaging in and harvesting the health benefits of physical activity. This pilot study explored active video gaming (AVG) as a way for patients with renal transplant to obtain physical activity and examined its effect on their functional status and quality of life (QOL). We recruited nine patients for an 8-week prospective pilot study. All patients received a Microsoft Xbox 360™ video gaming console, a Microsoft Kinect™ sensor, and the video game Your Shape Fitness Evolved 2012. Assessment of each participant before and after the intervention included blood pressure measures, a 6-minute walk test, and the Godin Leisure Time Questionnaire (GLTQ). We analyzed all nine patients at the end of the 8-week study period, and found no changes in blood pressure or GLTQ scores. However, there was a significant increase in the 6-minute walk distance (P = 0.022), which represented a consistent increase for most patients (correlation = 0.977). In addition, participants over the age of 45 years (n = 4) were more likely to use the AVG system (P = 0.042). AVG has the potential to improve the functional status in patients with renal transplant. Further research is required to corroborate the full health benefits of AVG in this patient population.

  10. Strongyloides Hyperinfection in a Renal Transplant Patient: Always Be on the Lookout

    Mazhar, Murtaza; Agudelo Higuita, Nelson Iván


    We present a case of a 71-year-old Vietnamese man with chronic kidney disease secondary to adult polycystic kidney disease. He had been a prisoner of war before undergoing a successful cadaveric renal transplant in the United States. He presented to clinic one year after the transplant with gross hematuria, productive cough, intermittent chills, and weight loss. Long standing peripheral eosinophilia of 600–1200/μL triggered further evaluation. A wet mount of stool revealed Strongyloides stercoralis larvae. A computed tomography (CT) of chest showed findings suggestive of extension of the infection to the lungs. The patient was treated with a three-week course of ivermectin with complete resolution of signs, symptoms, peripheral eosinophilia, and the positive IgG serology. Strongyloides infection in renal transplant patient is very rare and often presents with hyperinfection, associated with high mortality rates. The American Transplant Society recommends pretransplant screening with stool examination and Strongyloides stercoralis antibody in recipients and donors from endemic areas or with eosinophilia. It is imperative that healthcare professionals involved in the care of these individuals be cognizant of these recommendations as it is a very preventable and treatable entity. PMID:28316848

  11. Renal Transplantation Dramatically Reduces IgA Anti-beta-2-glycoprotein I Antibodies in Patients with Endstage Renal Disease

    Manuel Serrano


    Full Text Available IgA anti-beta-2-glycoprotein I (aB2GPI antibodies have been related to vascular pathology in the general population and mainly in hemodialyzed patients (prevalence 33% in whom an elevated incidence of thrombosis and mortality is found. In this paper we have studied the presence of IgA aB2GPI antibodies at pretransplant and their evolution after transplantation with a cross-sectional-based follow-up study of a cohort of 288 endstage renal disease (ESRD patients treated with kidney transplantation. Pretransplant IgA aB2GPI levels were elevated 31.7±4.2 U/mL without differences in age or type of dialysis. Patients with different etiologies of ESRD showed higher levels of IgA aB2GPI than blood donors, except the groups of non-IgA glomerular disease and systemic erythematosus lupus, whose nonsignificant differences were observed. IgA aB2GPI antibodies dropped immediately after transplantation (10.7±1.0 U/mL, P<0.0001, coinciding with a high degree of immunosuppression, and remained significantly lower than that observed in pretransplant status. Prevalence of patients with elevated antibodies was also less in transplanted patients (8.9% versus 30.4%, P<0.0001. Among, positivity for IgA aB2GPI was higher than in patients who had received their first transplant that those were retransplanted. This finding could have important clinical implications and can suggest new therapeutic strategies in patients with IgA aB2GPI antibodies.

  12. Relationship between immunosuppressive medications adherence and quality of life and some patient factors in renal transplant patients in Iran.

    Shabany Hamedan, Maryam; Mohamad Aliha, Jaleh


    About organ transplant, immunosuppressive medications adherence is a critical issue, because non-adherence to these medications causes rejection, reduces quality of life and increases treatment cost and mortality rate. Among these, the quality of life is deemed very important to evaluate treatment result and also it can be useful for discovering non adherence. The aim this study was to assess the relationship between medication adherence and quality of life and some patient factors in renal transplant patients. The study was a descriptive-correlational design and was done on renal transplant patients over 18 who had undergone surgery for over 3 months, and were inclined to participate. Sample size was 230 people and sampling was convenience. Quality of life questionnaire in renal transplant patients and Immunosuppressant Therapy Adherence Scale were filled by patients and the data was analyzed by SPSS15 software. It showed that the mean score of quality of life in renal transplant patients was 21.65±4.03 and 57.8% of them did not adhere to immunosuppressive medications. Results of correlation between scores of immunosuppressive medication adherence and Quality of life showed that there were significant correlation in 3 dimensions of 4: health performance (p ≤ 0.0001 & rETA=0.23), social-economic (p=0.001 & rETA=0.15), psychological-spiritual (p=0.011 & rETA=0.15), also logistic test showed significant relationship between immunosuppressive medication adherence and number of transplantation (?=1.04, p= 0.048). According to the results, health care providers i.e. nurses must note to medication adherence as a health enhancement factor while treating and educating to these patients.

  13. Renal Transplant Immunology in the Last 20 Years: A Revolution Towards Graft and Patient Survival Improvement.

    Sá, Helena; Leal, Rita; Rosa, Manuel Santos


    To deride the hope of progress is the ultimate fatuity, the last word in poverty of spirit and meanness of mind. There is no need to be dismayed by the fact that we cannot yet envisage a definitive solution of our problems, a resting-place beyond which we need not try to go. -P.B. Medawar, 1969* [Formula: see text] Thomas E. Starlz, also known as the Father of Clinical Transplantation, once said that organ transplantation was the supreme exception to the rule that most major advances in medicine spring from discoveries in basic science [Starzl T. The mystique of organ transplantation. J Am Coll Surg 2005 Aug;201(2):160-170]. In fact, the first successful identical-twin kidney transplantation performed by Murray's team in December 1954 (Murray J et al. Renal homotransplantations in identical twins. Surg Forum 1955;6:432-436) was the example of an upside down translation medicine: Human clinical transplantation began and researchers tried to understand the underlying immune response and how to control the powerful rejection pathways through experimental models. In the last 20 years, we have witnessed an amazing progress in the knowledge of immunological mechanisms regarding alloimmune response and an outstanding evolution on the identification and characterization of major and minor histocompatibility antigens. This review presents an historical and clinical perspective of those important advances in kidney transplantation immunology in the last 20 years, which contributed to the improvement in patients' quality of life and the survival of end-stage renal patients. In spite of these significant progresses, some areas still need substantial progress, such as the definition of non-invasive biomarkers for acute rejection; the continuous reduction of immunosuppression; the extension of graft survival, and finally the achievement of real graft tolerance extended to HLA mismatch donor: recipient pairs.

  14. Systemic and Nonrenal Adverse Effects Occurring in Renal Transplant Patients Treated with mTOR Inhibitors

    Gianluigi Zaza


    Full Text Available The mammalian target of rapamycin inhibitors (mTOR-I, sirolimus and everolimus, are immunosuppressive drugs largely used in renal transplantation. The main mechanism of action of these drugs is the inhibition of the mammalian target of rapamycin (mTOR, a regulatory protein kinase involved in lymphocyte proliferation. Additionally, the inhibition of the crosstalk among mTORC1, mTORC2, and PI3K confers the antineoplastic activities of these drugs. Because of their specific pharmacological characteristics and their relative lack of nephrotoxicity, these inhibitors are valid option to calcineurine inhibitors (CNIs for maintenance immunosuppression in renal transplant recipients with chronic allograft nephropathy. However, as other immunosuppressive drugs, mTOR-I may induce the development of several adverse effects that need to be early recognized and treated to avoid severe illness in renal transplant patients. In particular, mTOR-I may induce systemic nonnephrological side effects including pulmonary toxicity, hematological disorders, dysmetabolism, lymphedema, stomatitis, cutaneous adverse effects, and fertility/gonadic toxicity. Although most of the adverse effects are dose related, it is extremely important for clinicians to early recognize them in order to reduce dosage or discontinue mTOR-I treatment avoiding the onset and development of severe clinical complications.

  15. 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.

  16. NSS for an RCC in a patient with renal insufficiency after heart transplant because of right ventricular tumor.

    Prokopowicz, Grzegorz; Zyczkowski, Marcin; Nowakowski, Krzysztof; Bryniarski, Piotr; Paradysz, Andrzej


    The effect of the immunosuppressive therapy on the development of neoplasms has become the object of an ever increasing interest for clinicians all over the world. The literature on neoplasms development in the course of therapy following transplants has confirmed a considerable increase in the incidence of neoplasms of the skin and lymph nodes. Organ neoplasms developing in patients after transplants are characterized by increased progression, poor cellular diversification and a more unfavorable prognosis than in the general population The aim of the study is to present the case of a nephron-sparing surgery of a renal tumor (NSS) without any intraoperative ischaemia in a 55-year-old female patient with an orthotopic heart transplant and renal insufficiency following a prolonged immune suppression. It is estimated that the patients at the highest risk of neoplasm development are those in the first months after transplant, especially heart transplant. They require maximum doses of immunosuppressive drugs. In the case of patients with initial renal insufficiency the duration of ischaemia of the organ operated on should be minimized, and if possible, surgery should be conducted without clamping the renal pedicle. The surgical treatment of RCC (renal cell carcinoma) in transplant patients does not require any reduction in the amount of the immunosuppressive drugs.

    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.

    Posadzy-Małaczyńska, Anna; Kosch, Marcus; Hausberg, Martin; Rahn, Karl H; Małaczyński, Paweł; Głuszek, Jerzy; Tykarski, Andrzej


    Structural and mechanical properties of the arterial wall are altered in patients with renal failure. Age and hypertension are known to affect the vessel wall structure. Aging process of arterial wall appears to be accelerated in patients with end-stage renal failure. The mechanisms responsible for reduced arterial compliance and distensibility in dialyse patients and renal transplant recipients without hypertension remain to be evaluated. 20 normotensive dialyse patients (D), 20 normotensive renal transplant recipients (T) and 20 healthy volunteers (N) matched for age, sex and blood pressure as controls were enrolled in to the study. Patients with cardiovascular risk factors and diabetes were excluded. The arterial blood pressure of all patients placed below 140/90 mmHg. The dialyse patients and renal transplant recipients were eligible for the study if the serum creatinine level was below 2 mg/dl. In all subjects, fasting concentrations of serum creatinine, total cholesterol, HDL-cholesterol, LDL-cholesterol, hemoglobin and glucose were determined at enrollment to the study. Long-term immunosuppression consisted of cyclosporine and prednisolone. Blood pressure was measured using an automatic sphygmomanometer (Criticon Dinamap model 1846 SX). Pulse wave velocity (PWV) was evaluated using non-invasive automatic Complior device. The vessel wall properties of the left common carotid artery were studied using multigate pulsed Doppler's system (Pie Medical Equipment BV Maastricht, The Netherlands). The frequency of transducer used was 7.5 MHz. With this non-invasive method, the end-diastolic diameter (d) and the systolic increase of vessel diameter (distension delta d) were measured using ECG trigger. From these data relative systolic increase of vessel diameter (delta d/d) and arterial wall distensibility coefficient (DC) were calculated. Simultaneously with the ultrasound measurements at the left common carotid artery carotid pulse waveforms are recorded using

  19. 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.

  20. PD1-Expressing T Cell Subsets Modify the Rejection Risk in Renal Transplant Patients

    Pike, Rebecca; Thomas, Niclas; Workman, Sarita; Ambrose, Lyn; Guzman, David; Sivakumaran, Shivajanani; Johnson, Margaret; Thorburn, Douglas; Harber, Mark; Chain, Benny; Stauss, Hans J.


    We tested whether multi-parameter immune phenotyping before or after renal ­transplantation can predict the risk of rejection episodes. Blood samples collected before and weekly for 3 months after transplantation were analyzed by multi-parameter flow cytometry to define 52 T cell and 13 innate lymphocyte subsets in each sample, producing more than 11,000 data points that defined the immune status of the 28 patients included in this study. Principle component analysis suggested that the patients with histologically confirmed rejection episodes segregated from those without rejection. Protein death 1 (PD-1)-expressing subpopulations of regulatory and conventional T cells had the greatest influence on the principal component segregation. We constructed a statistical tool to predict rejection using a support vector machine algorithm. The algorithm correctly identified 7 out of 9 patients with rejection, and 14 out of 17 patients without rejection. The immune profile before transplantation was most accurate in determining the risk of rejection, while changes of immune parameters after transplantation were less accurate in discriminating rejection from non-rejection. The data indicate that pretransplant immune subset analysis has the potential to identify patients at risk of developing rejection episodes, and suggests that the proportion of PD1-expressing T cell subsets may be a key indicator of rejection risk.

    Souqiyyeh Muhammad


    Full Text Available The goal of this study was to evaluate the attitude of the physicians towards the follow-up of the renal transplant patients in the Kingdom of Saudi Arabia (KSA. We sent a questionnaire to 168 physicians working in 148 active dialysis centers in the KSA. The study was conducted from June-October 2005. There were 140 physicians (83.3% who answered the questionnaire; they represented 136 (91.9% dialysis centers. There were 43 (31.2% respondents who had a transplant clinic for follow-up of transplant recipients. Of the 96 (69.1% who did not have a clinic, 29 (30.2% claimed expertise for follow-up of transplant recipients, six (6.2% had a laboratory set-up to monitor the immunosuppressive drug levels and 40 (44.4% felt the need for one. There were 121 (89% respondents who would consider the chronic renal failure (CRF patients for transplantation because it is the best form of therapy. Seventy-seven respondents (55% had a protocol for work-up of the CRF patients for transplantation, 31 (22.3% had a coordinator for the work-up of the transplant candidates, 34 (24.5% had regular meetings to decide on the waiting list for transplantation, and 51 (37.8% had affiliation with, or worked at a transplant center. Nevertheless, 127 (90.7% respondents believed that the results of renal transplantation were good enough to recommend the procedure to all patients as early as possible. There were 133 (97.1% respondents who believed that organ shortage was the major factor for the low percentage of renal transplantation. Only 52 (37.1% respondents knew about the recent regulations established by the World Health Organization (WHO for organ donation. There were 63 (48.1% respondents who believed that seeking commercial renal transplantation outside the KSA to be unacceptable because of the medical and ethical complications involved.

    Full Text Available Aim. Treatment of urosepsis in patients after renal transplantation is very difficult. Currently selective endotoxin adsorption is a perspective method of treatment. Works devoted to the study of the effectiveness of this method in patients with renal transplant are extremely rare. Materials and methods. 94 recipients were included in study: 54 in prospective main group and 40 – in retrospective comparison group. For each patient of the main group we performed 2 sessions of selective endotoxin adsorption. Patients of comparison group were not trea- ted with sorption of endotoxin. We investigated the dynamics of APACHE II score, the concentration of IL-6, IL-8, TNF-alpha, procalcitonin and endotoxin. Results. As a result of endotoxin adsorption there was noted more pronounced decrease in the APACHE II score in patients of the main group, than in the comparison group. There was a decrease in activity of the systemic inflammatory response, and that was reflected in the decrease in the concentration of proinflammatory cytokines and procalcitonin in patients of the main group. Application of endotoxin adsorption resulted in a significant increase in survival in patients of the main group. Conclusion. Sorption of endotoxin is very effective and safe procedure that affects the pathogenesis of sepsis. Application of this procedure can significantly improve the condition of patients and survival. 

  3. [Hepatitis B virus in patients with renal transplant. Report of 52 cases].

    Duncan, C R; Virginillo, M B; Palmitano, J B; Tani, R D; Aguirre, C


    Hepatitis B virus (HBV) is a high risk factor in the frequently found liver involvement of renal transplant recipients. As in other immunosuppressed patients, these often follow a course of slight jaundice, with a progressive tendency and great replicative and infectious power. Also, in addition to an increased incidence of chronic hepatitis (CH) in transplanted when compared with hemodialized patients, specially when HBsAg is present, it is surprising the poor correlation between enzyme levels and the grade of activity of the hepatic lesion. In a retro and prospective study, we present 52 patients of the 73 transplant reviewed. There are 32 men and 20 females, with and average age of 34 years, minimum time on dialysis of 2 months and maximum of 7 years, time of renal transplant from 6 moth to 15 years (average 4.9 years). There were 31 cadaver transplants and 21 live donors. The HBsAg was + in 20 (9 seroconverted), HBeAg was + in 4 (with 2 seroconvertions), hyperbilirrubinemia in 5, hyperalkaline phosphatasemia (2 or more times) in 11 and elevated serum transaminases (SGPT) (3 times or more) in 20 cases. Positive HBsAg plus SGPT x 3 was found on 9 occasions and positive HBsAg with SGPT x 3 in 3 cases. liver biopsy (LB), in those with enzymatic changes and/or positive antigenemia, was performed in 15 instances and there were 5 autopsies. The most important histological findings were: 5 acute viral hepatitis, 2 active chronic hepatitis (CAH), 2 persistent chronic hepatitis (CPH), 5 with fat infiltration and 4 with colestasis.(ABSTRACT TRUNCATED AT 250 WORDS)

    Purpose: To assess the value of functional magnetic resonance urography for the noninvasive postoperative evaluation of renal transplants. Methods: A saturation inversion projection sequence allows the selective imaging of strongly T1 weighted signal from the MR contrast agent. A coronal slab leads to images comparable to conventional urography which can be acquired as a sequence with four images per minute. Results: 15 patients with urologic questionable findings after renal transplantation were studied. FMRU revealed in 6 patients normal findings, in 6 moderate dilatation of the renal pelvis without any urodynamic relevant obstruction. 3 pathologic findings, ureteral leak, ureteropelvic-junction obstruction and ureteral stenosis were diagnosed and consequently surgically treated. The imaging quality in all studies was diagnostic and urologically relevant. Conclusion: FMRU can be used as a noninvasive technique for the assessment of renal transplant in cases with suspicion of complication in the excretory system. (orig.) [Deutsch] Fragestellung: Laesst sich die funktionelle Magnetresonanzurographie (FMRU) zur nichtinvasiven Diagnostik im postoperativen Verlauf von Nierentransplantaten einsetzen? Methodik: Mit Hilfe einer Saturation-Inversion-Projektionstechnik kann eine selektive Darstellung der durch das Kontrastmittel stark verkuerzten T1-gewichteten Signalanteile erreicht werden. Durch koronare Schichtfuehrung entstehen Bilder vergleichbar mit einer konventionellen Urographie, die als Sequenz von 4 Bildern pro Minute aufgenommen werden. Ergebnisse: 15 Patienten mit urologisch abklaerungsbeduerftigen Befunden nach Nierentransplantation wurden untersucht. Mit der FMRU konnte bei 6 Patienten ein unauffaelliger Befund, bei 6 eine diskrete Dilatation des Nierenbeckenkelchsystems ohne urodynamisch relevante Abflussbehinderung nachgewiesen werden, jeweils eine Harnleiterleckage, eine Harnleitermuendungsstenose und eine Harnleiterabgangsenge wurden diagnostiziert und

  7. Case report: boldo (Peumus boldus) and tacrolimus interaction in a renal transplant patient.

    Carbajal, R; Yisfalem, A; Pradhan, N; Baumstein, D; Chaudhari, A


    Boldo is an extract of a Chilean tree leave (Peumus boldus mol) that have been traditionally employed in folk medicine. We have presented a case of subtherapeutic tacrolimus levels in a renal transplant patient while taking boldo. In the literature search, no interaction has been reported between boldo and tacrolimus. A 78-year-old Hispanic man with history of diabetes mellitus, hypertension, and deceased donor renal transplant in 2005 presented to the renal clinic for regular follow-up on September 1, 2010. No complaints were reported and physical examination was unremarkable. Laboratory tests taken on July 26, 2010, were significant for tacrolimus level of <3 ng/mL (measured by liquid chromatography/tandem mass spectrometry) and serum creatinine of 1.2 mg/dL (106 μmol/L). Medications included tacrolimus 2 mg bid and mycophenolate 500 mg bid. On further inquiry, the patient admitted taking herbal medication, boldo 300 mg bid, for the last few weeks. There was no change in his regular medications. He was adherent to his medication. He had been taking tacrolimus from the same company and pharmacy since August 2009. The last dose of boldo was on September 1, 2010. One week after he stopped taking boldo, tacrolimus level was 6.1 ng/mL (9/8/2010) on the same tacrolimus dose of 2 mg bid. Tacrolimus dose was increased to 3 mg bid (9/9/2010), awaiting tacrolimus levels. Subsequent levels (ng/mL) were 8.6 and 9.5, which made us resume the prior tacrolimus dose (2 mg bid). We have reported a case of an allograft renal transplant recipient who presented to the clinic with subtherapeutic levels of tacrolimus while taking the herbal remedy boldo. Tacrolimus levels rose to the intended target after discontinuation of boldo. Although it is a single case report, our observation suggests a possible herb-drug interaction.

  8. Long-term follow-up of renal transplant patients with renal artery stenosis treated by percutaneous angioplasty

    Peregrin, Jan H. [Department of Diagnostic and Interventional Radiology, Institute for Clinical and Experimental Medicine, Videnska 1958/9, 14021 Prague 4 (Czech Republic)], E-mail:; Stribrna, Jarmila [Department of Diagnostic and Interventional Radiology, Institute for Clinical and Experimental Medicine, Videnska 1958/9, 14021 Prague 4 (Czech Republic); Lacha, Jiri [Department of Nephrology, Institute for Clinical and Experimental Medicine, Videnska 1958/9, 14021 Prague 4 (Czech Republic); Skibova, Jelena [Statistical Department, Institute for Clinical and Experimental Medicine, Videnska 1958/9, 14021 Prague 4 (Czech Republic)


    Purpose of the study: To evaluate if renal angioplasty (PTRA) in patients with transplanted kidney and renal artery stenosis (TRAS) can have long-term effect on hypertension and renal function. Materials and methods: Within a 24-year time period, 58 PTRAs in 55 adults (three times Re-PTRA) with transplanted kidney were performed. The group included 34 males and 21 females, average age 41 {+-} 10.6 (18-72) years. After exclusion of 7 technical failures, 51 PTRAs were followed at 1 week, 6 months and 1-3 years after PTRA. Hypertension improvement was defined as mean arterial pressure (MAP) decrease of at least 15% from the pre-PTRA value. Graft function was evaluated by serum creatinine (Scr) and creatinine clearance (Ccr) levels, and the improvement was defined as a 20% change. Clinical FU was 3 years. Results: PTRA technical success was 88.4%. In 51 kidney recipients at the end of FU, blood pressure improved in 65.2% of patients (MAP decreased from 123 {+-} 13.1 to 107 {+-} 12.1 mmHg), but no patient remained normotensive medication free. Graft function improved in 44.8% of patients and was stabilized in 20.7% of them (average Ccr before PTRA: 0.48 {+-} 0.29, after PTRA: 0.78 {+-} 47 ml/s). PTRA complications were observed in 25.5% of procedures, most often with no clinical sequel. Thirty days mortality was 1.8% (one patient). Conclusions: PTRA results in kidney recipients are valuable mainly in preserving graft function.

  9. [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.

  11. Medication compliance in renal transplant patients during the Great East Japan Earthquake.

    Kadowaki, M; Saito, M; Amada, N; Haga, I; Nakamura, A; Tokodai, K


    Oral immunosuppressant suspension induces renal graft dysfunction in renal transplant patients. After the Great East Japan Earthquake, not only were drugs lost in the tsunami, but visiting hospitals became difficult owing to information and transportation network disruption. We investigated medication compliance in renal transplant patients and actions taken immediately after the earthquake. We included 315 patients who were visiting our outpatient department as of March 11, 2011, from June to August 2011. Information was collected from questionnaires, medical records, and outpatient diaries. The questionnaire collection rate was 93%, with valid replies from 296 patients. One hundred eighty-five patients (62%) had stockpiled oral medications before the earthquake; of these, 131 (44%) always carried medications with them. Forty-five patients (16%) had difficulties with continuing oral immunosuppressants after the earthquake (supply delay, 29 patients; drugs lost in tsunami, 9; others, 10). Of these 48, oral medication was suspended in 18 for 3 days at maximum. As to outpatient prescriptions, out-of-hospital prescriptions were sent by fax to 17 patients, prescription drugs were sent from our hospital by mail or home delivery services to 11, and prescriptions were given to 13 who visited other hospitals. Because of the difficulty in requesting prescriptions from disaster base hospitals, drugs prescribed at our hospital were delivered to 3 severely damaged institutions for patients living in surrounding areas. After the earthquake, our usual self-management guidance proved effective. Further examination of the infrastructure for communicating with patients and supplying drugs is needed.

  12. Treatment of pure red-cell aplasia with cyclosporine in a renal transplant patient.

    Yildirim, Rahsan; Bilen, Yusuf; Keles, Mustafa; Uyanik, Abdullah; Gokbulut, Puren; Aydinli, Bulent


    Acquired pure red-cell aplasia is a rare disorder that can be either idiopathic or associated with certain autoimmune diseases, pregnancy, lymphoproliferative disorders, nutritional deficiencies, or medicines. We present a deceased-donor renal transplant patient who developed pure red-cell aplasia associated with mycophenolate mofetil or tacrolimus and was treated with cyclosporine. A 20-year-old woman was transplanted from a deceased donor 1 month earlier and presented to us with symptoms of fatigue, prostration, and palpitation. The results of a laboratory examination revealed anemia. A diagnostic work-up resulted in a diagnosis of pure red-cell aplasia. Mycophenolate mofetil was discontinued. Tacrolimus also was replaced with cyclosporine 2 months after mycophenolate mofetil was halted because of a lack of improvement in anemia. Three months later, her anemia improved with cyclosporine. Starting cyclosporine instead of tacrolimus or mycophenolate mofetil showed good improvement in our patient within 6 months of therapy.

  13. Short-Term Outcome of Untreated Versus Treated Asymptomatic Bacteriuria in Renal Transplant Patients.

    Arencibia, N; Agüera, M L; Rodelo, C; López, I; Sánchez-Agesta, M; Hurtarte, A; Navarro, M D; Rodríguez-Benot, A


    Infection of the urinary tract (UTI) is the most common form of bacterial infection in renal transplant patients, but its management is still controversial. We compared symptomatic and asymptomatic bacteriuria, treated or untreated, during two different months (summer or winter). This longitudinal, prospective study involved routine urine cultures collected during September 2014 or March 2015. Demographic, clinical, and microbiological characteristics from the patients with positive urine cultures were described. The main outcomes were the need of hospitalization, the bacterial clearance, and the selection of the resistant pathogen. From the 538 urine cultures collected, only 61 were positive urine cultures. Twenty were untreated asymptomatic bacteriuria (AB), 28 were treated AB, and 13 were treated symptomatic bacteriuria. The more prevalent micro-organisms were E coli (27%), K pneumoniae (11%), and E faecalis (7%). There were no differences in the demographic, clinical, and microbiological characteristics depending on the month when the urine cultures were collected. Only 10 patients required hospitalization during follow-up, and all of them belonged to the treated group. Bacterial clearance after the treatment occurred in 20 patients of the 41 treated (48.9%) and spontaneously in 14 of the 20 patients untreated (70%). Of the treated patients, 47.6% developed a new resistance to another antibiotic. Only 7.6% of the routine urine cultures on renal transplant were positive. Untreated AB did not require hospitalization, and 70% had spontaneous bacterial clearance. Copyright © 2016 Elsevier Inc. All rights reserved.

  14. Optimization of Cyclosporine Therapy with Predicted AUC in Renal Transplant Patients


    Background: Pre-dose concentration measurement is the most practical method to evaluate cyclosporine(CsA) therapy in renal transplant patients. But it gives no information about the total drug exposure,which relate to graft survival. A number of different new concepts of CsA monitoring,including approaches such as single,double,triple time-point and abbreviated area under curve(AUC) determinaiton,have been introduced. The full CsA AUC value is the most sensitive indicator of clinical outcome. However,its higher analytical costs and time-consuming sampling compromise the benefit of full AUC. Alternative method of predicted AUC by using 2 concentration-time points have been established and used for routine practice in our hospital. [Objectives] The purpose of this study is to determine more sensitive and more predictive markers for CsA dosage adjustment in renal transplant patients. [Methods] Total 44 patients completed the 12-hours CsA pharmacokinetic studies. They had stable renal function. None of them had history of gastrectomy,small bowel resection,cholecystectomy,cholestasis,or had use of medications that might cause an interaction with CsA before the study. Pharmacokinetic parameters were evaluated by use of noncompartmental methods. The correlation equations between drug concentration-time points and AUC were determined by simple and multiple linear regression models using one,two,or three concentration time points as independent variable. [Results] Most of Cmax achieved at about 1~2 hours after dosing,but some delayed absorption was observed at abour 3~5 hours after dosing. C0 and C1 are poorly correlated with AUC of CsA,two of three point have better correlation than single point. Depending on clinical outcomes,predicted AUC goes more reliable than single concentration-time point monitoring for consideration of total exposure amount of CsA. If Tmax of CsA concentration-time curve shifted(delayed) out of population range,the AUC prediction error will be

  16. Embolization of renal arteries before transplantation in patients with polycystic kidney disease: a single institution long-term experience

    Petitpierre, F.; Cornelis, F.; Lasserre, A.S.; Tricaud, E.; Le Bras, Y.; Grenier, N. [Pellegrin Hospital, Department of Radiology, Bordeaux (France); Couzi, L.; Merville, P. [Pellegrin Hospital, Department of Nephrology, Bordeaux (France); Combe, C.; Ferriere, J.M. [Pellegrin Hospital, Department of Urology, Bordeaux (France)


    We aimed to retrospectively assess the long-term safety and efficacy of embolization of renal arteries (ERA) in patients with polycystic kidney disease (PKD) before renal transplantation. Between January 2008 and November 2013, 82 ERA procedures were performed on 76 kidneys in 73 patients (mean age 53 years, range: 34-72). All patients had terminal-stage PKD and were under dialysis and on the renal transplant waiting list with a temporary contraindication due to excessive renal volume. ERA was considered successful in 89.5 % (68/76) of embolized kidneys, meaning that the temporary contraindication for transplantation could be withdrawn for 65 patients (on average 5.6 months, range: 2.8-24.3, after ERA). Mean volume reduction was 40 (range: 2-69) at 3 months and 59 % (35-86) thereafter (both p < 0.001). Post-embolization syndrome occurred after 15 of 82 procedures (18.3 %). The severe complication rate was 4.9 %. Forty-three (67.7 %) transplantations were successfully conducted after ERA, with a mean follow-up of 26.2 months (range: 1.8-59.5), and the estimated 5-year graft survival rate was 95.3 % [95 % CI: 82.7-98.8]. ERA is a safe and effective alternative to nephrectomy before renal transplantation in patients with PKD. (orig.)

  17. Human leucocyte antigens: their association with end-stage renal disease in Saudi patients awaiting transplantation.

    Almogren, A; Shakoor, Z; Hamam, K D


    Most patients with chronic renal failure develop end-stage renal disease (ESRD) that requires renal transplantation. This study investigates the possible associations between human leucocyte antigen (HLA) Class I and Class II molecules with ESRD. Genotyping data (HLA) obtained between 2005 and 2009 on 235 unrelated Saudi patients (147 males, 88 females; mean age: 58 +/- 7 years) with ESRD awaiting renal transplantation were assessed retrospectively at the King Khalid University Hospital. Data were compared with the results on 60 normal, healthy, unrelated Saudi individuals (37 males and 23 females; mean age: 51 +/- 5 years). HLA Class I and Class II antigens were detected by lymphocytotoxicity and a polymerase chain reaction (PCR) method using DNA sequence-specific primers. Although present in small numbers, HLA Cw2 was found in significantly fewer patients (n = 11; 4.68%) compared to normal subjects (n = 9; 15%) and was found to confer protection against ESRD (P = 0.005; relative risk [RR]: 3.594, 95% confidence interval [CI]: 1.415-9.126). Among the HLA Class II antigens, HLA DQB1*03(8) was detected more frequently in the patient group (n = 65; 27.6%) than in the normal controls (n = 9; 15%) and was positively associated with risk of ESRD (P = 0.04; RR: 0.462, 95% CI: 0.215-0.991). No significant differences were observed between the two groups in respect of HLA-A2, HLA-B50(21), HLA-B51(5) and HLA-Cw7 (HLA Class I), and HLA-DRB1*04, HLA-DRB1*07 and HLA-DQB1*02 (HLA Class II). Occurrence of the most frequent HLA alleles was no different between the ESRD group and the controls. The protective role of HLA-Cw2 and the marginal susceptibility associated with HLA-DQBI*03(8) for ESRD requires further investigation.

    Intravenous immunoglobulin (IVIG) and/or plasmapheresis (PP) are effective in preventing antibody-mediated rejection (AMR) of kidney allografts, but AMR is still a problem. This study reports our experience in living donor renal transplantation in highly sensitized patients. Ten patients with positive crossmatch tests or high levels of panel-reactive antibody (PRA) were included. Eight patients were desensitized with pretransplant PP and low dose IVIG, and two were additionally treated with rituximab. Allograft function, number of acute rejection (AR) episodes, protocol biopsy findings, and the presence of donor-specific antibody (DSA) were evaluated. With PP/IVIG, six out of eight patients showed good graft function without AR episodes. Protocol biopsies revealed no evidence of tissue injury or C4d deposits. Of two patients with AR, one was successfully treated with PP/IVIG, but the other lost graft function due to de novo production of DSA. Thereafter, rituximab was added to PP/IVIG in two cases. Rituximab gradually decreased PRA levels and the percentage of peripheral CD20+ cells. DSA was undetectable and protocol biopsy showed no C4d deposits. The graft function was stable and there were no AR episodes. Conclusively, desensitization using PP/IVIG with or without rituximab increases the likelihood of successful living donor renal transplantation in sensitized recipients. PMID:19194545

  19. 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.

    P. R. Shah


    Full Text Available Introduction. Hepatitis C virus (HCV infection is an independent risk factor for renal transplantation (RTx. Immunosuppression minimization can render better quality of life to these patients. Methods. We analyzed 132 HCV-positive RTx patients (group A transplanted under tolerance induction protocol (TIP and compared them with 79 controls (group B transplanted using standard triple drugs. TIP consisted of 1 donor-specific transfusion, peripheral blood stem cell infusion, portal infusion of bone marrow, and target-specific irradiation. Their immunosuppression was cyclosporin, 2 ± 1 mg/kg BW/day + prednisone, 10 mg/day. Results. TIP had no side effects. Although unequal in size, the groups were well balanced. Group A patient survival at 1, 5, and 10 years was 92.4%, 70.4%, and 63.7%, respectively, versus 75.6%, 71.7%, and 55.7% in later, and graft survival was 92.9%, 81.5%, and 79.1% versus 91.7%, 75.7%, and 67.7%, respectively. Mean serum creatinine (mg/dL at these time periods in former was 1.38, 1.72, and 1.87, versus 1.3, 1.75, and 2.1 in later. Altered liver functions were noted in 22% patients in former versus 31% in later. Group A had lesser rejection episodes. Conclusion. RTx using TIP in HCV-positive patients is a viable option with acceptable outcome.

  1. Antibiotic failure in a renal transplant patient with Rhodococcus equi infection: an indication for surgical lobectomy.

    Ursales, A; Klein, J A; Beal, S G; Koch, M; Clement-Kruzel, S; Melton, L B; Spak, C W


    Rhodococcus equi is an animal pathogen that causes infrequent but challenging infections in immunocompromised individuals, few of which have been described in solid organ transplant recipients. Common clinical presentations include indolent cough, fever, and dyspnea, with necrotizing pneumonia and cavitation. We report a case of a dense right upper lung pneumonia with resultant R. equi bacteremia in a renal transplant recipient. Our patient initially responded to antibiotic treatment with resolution of bacteremia and clinical recovery, followed by interval progression in her right upper lobe consolidation on follow-up computed tomography scans. She underwent lobectomy for definitive therapy with resolution of symptoms. Lobectomy can be utilized in isolated infection after antibiotic failure with excellent clinical outcomes. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Objectives. The aim of the study was to present the case of a patient after renal transplantation who developed psychotic depression. Methods. Analysis of the clinical case and medical history. Results. 33-year-old patient with an earlier episode of psychotic depression and kidney transplant was admitted to the ward in critical condition. Due to the heavy somatic condition, denial of food, fluids and medications intake, urinary tract infection, inefficiency and nephrotoxicity of pharmacotherapy we decided to apply electroconvulsive therapy with phenomenal therapeutic response after the first treatment. Conclusions. Psychotic depression is a severe disorder often requiring rapid and complex treatment. In this case, an attempt of applying electroconvulsive therapy (ECT, because of life threatened state, was tried. Due to the lack of literature, and to date not fully elucidated the mechanism of action of ECT, it remains a mystery the fact that the therapeutic response was so clear and rapid. The authors hypothesize that this is due to the young age of the patient, the absence of organic changes and a brief medical history. Further research in this area may contribute to a better understanding of the described changes. The present case may be an indication for clinicians to attempt the use of ECT in patients after kidney transplantation with concomitant psychotic depression.

  3. Timing for Removal of Peritoneal Dialysis Catheters in Pediatric Renal Transplant Patients.

    Melek, Engin; Baskın, Esra; Gülleroğlu, Kaan Savaş; Kırnap, Mahir; Moray, Gökhan; Haberal, Mehmet


    Peritoneal dialysis, the preferred long-term renal replacement modality in the pediatric population, can also be used during the post transplant period. Although it is well known that peritonitis or other complications may occur related to the peritoneal dialysis catheter, less is known about complications related to the peritoneal dialysis during the posttransplant period. Our objective was to evaluate the complications related to use of a peritoneal dialysis catheter during the posttransplant period and to determine the optimum time for removal of the peritoneal dialysis catheter. We retrospectively analyzed 33 chronic peritoneal dialysis patients. Pretransplant and posttransplant demographics and clinical and laboratory data for each patient were recorded, including incidence of peritonitis and incidence of peritoneal dialysis catheter requirement after transplant. Mean age of patients at transplant was 12.8 ± 4.0 years (range, 3.5-18.0 y). Mean catheter removal time was 81.1 ± 36.2 days (range, 22.0-152.0 d). The peritoneal dialysis catheter was used in 6 of 33 patients (18.2%); none of these patients developed peritonitis. In contrast, 2 of the 27 patients who did not use the peritoneal dialysis catheter developed peritonitis. Our data suggest that the need for catheter use occurs predominantly during the first month, and infectious complications usually happen later. Previously, the trend was to not remove the peritoneal dialysis catheter at the time of transplant. However, in light of recent literature and our present study, we recommend that the time of catheter removal should be modified and decided for each patient on an individual basis.

These species are vasotropic, causing rapid onset of tissue infarctions and necrosis and subsequent thrombosis by invading vascular bed. The disease spectrum ranges from involvement of skin, sinuses, lung, and brain to disseminated and mostly fatal infections, especially in immunocompromised hosts. Here, we present a case of a fatal disseminated mucormycosis in a 56-year-old female who had deceased donor renal allograft transplantation ~2 weeks prior to presentation. She presented with shortness of breath and dry cough. Despite being on broad-spectrum antibiotics/antifungals and proper management by transplant, infectious disease, and primary team, she died within 3 weeks of admission. Autopsy showed disseminated mucormycosis of lungs and thyroid. Disseminated infection within 2 weeks of solid organ transplantation in this patient was one of the rare features of mucormycosis.

    Full Text Available The objective of this study was to assess the effect of hepatitis C virus (HCV infection on graft and patient survival in a cohort of Libyan renal transplant recipients. Medical records of 241 renal transplant (RT patients who have been followed-up at the Benghazi Nephrology Center up to February 2010 were reviewed. Based on the presence or absence of anti-HCV antibodies and HCV-RNA in the serum, patients were divided into two groups: HCV-positives and HCV-negatives. Anti-HCV antibodies were detected by the enzyme-linked immunosorbent assay technique and HCV-RNA by the polymerase chain reaction. Of the 241 RT patients, 162 were male and 79 were female. One hundred and ten patients (45.6% were HCV-positives and 131 (54.4% were HCV-negatives. Acute graft rejection was significantly higher among HCV-negative than HCV-positive patients (42 patients versus 28 patients, respectively; P < 0.001. Conversely, chronic graft rejection was higher among HCV-positives than that among HCV-negative patients (35 patients versus 24 patients, respectively; P <0.05, and this difference became more significant after a 12-month period of transplantation (P <0.01. Seventeen patients died during the follow-up: Seven HCV-positives (6.3% and 10 HCV-negatives (7.6%, and there was no significant difference in the death rate following RT between the two groups (P = 0.08. Among the seven deaths of HCV-positives, liver disease-related complications were the main cause of death in three (42.8% HCV-positive patients compared with none in the HCV-negative patients. The presence of HCV infection influenced chronic graft survival in RT patients and a higher proportion of HCV-infected patients had hepatic dysfunctions after RT. An increase in fatal liver complications was noted in HCV-positive patients with RT. In addition to pre-RT-specific therapy of HCV infection, all measures should be taken to prevent HCV infection pre- and post-RT. HCV-infected RT recipients need close

  7. Intraoperative Diagnosis of Stanford Type A Dissection by Transesophageal Echocardiogram in a Patient Presenting for Renal Transplantation

    Hand, William R.; Ikonomidis, John S.; Bratton, Charles F.; Thomas M. Burch; McEvoy, Matthew D.


    A 48-year-old patient with hypertensive end-stage renal disease presented for cadaveric renal transplantation. On physical exam, a previously undocumented diastolic murmur was heard loudest at the left lower sternal border. The patient had a history of pericardial effusions and reported “a feeling of chest fullness” when lying flat. As such, a transesophageal echocardiogram (TEE) was performed after induction of anesthesia to evaluate the pericardial space and possibly determine the etiology ...

  8. 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.

    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.

    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.

  13. 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

    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.

  15. 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.

  16. Cryptococcal necrotizing fasciitis in a patient after renal transplantation--a case report.

    Yoneda, T; Itami, Y; Hirayama, A; Saka, T; Yoshida, K; Fujimoto, K


    A 50-year-old man, who had received an ABO-incompatible living related preemptive renal transplantation 1 year before, presented with painful lesions on both lower extremities and fever. At first, bacterial cellulitis was suspected and antibiotic therapy was initiated, but it was not effective. The serum cryptococcal antigen titer was 1:4,098, and pathologic examination of debrided tissue and wound pus culture revealed cryptococcal necrotizing fasciitis. Liposomal amphotericin B and fluconazole were started, and repeated debridement and skin grafting were performed. Because his graft function deteriorated because of antibody-mediated rejection and polyoma viral nephropathy, hemodialysis was induced on day 9 of hospitalization. During the treatment, he suffered repeated urinary tract infections, which were treated with antibiotics, and cytomegalovirus retinopathy, which was treated with ganciclovir. His cryptococcal necrotizing fasciitis was successfully cured by the combination of antimicrobial treatment and surgical procedures. He could walk with a cane and was discharged on day 298 of hospitalization. Cryptococcal necrotizing fasciitis in renal transplant recipients is so rare that only 14 cases have been reported. The mortality is not very high, but the prognosis of the patient is complicated by worsening of the cryptococcal infection of the central nervous system (CNS). Early detection and treatment to prevent spreading to other sites, especially the CNS or disseminated disease, is very important in cases of cryptococcal necrotizing fasciitis.

  17. Intrahepatic cytokine profile in renal-transplant patients infected by hepatitis C virus.

    Kamar, Nassim; Rostaing, Lionel; Sandres-Saune, Karine; Selves, Janick; Barthe, Carole; Dubois, Martine; Alric, Laurent; Durand, Dominique; Izopet, Jacques


    In order to examine the immunopathogenesis of hepatitis C virus (HCV)-related liver injury in renal-transplant patients, intra-hepatic cytokine profiles were examined in 38 liver biopsies from 38 patients by measuring messenger RNA (mRNA) concentrations by a real-time PCR method of a Th1 cytokine (i.e., interferon (IFN)-gamma), a Th2 cytokines (i.e., interleukine (IL)-10), a proinflammatory cytokine (i.e., IL-8), and a potent fibrogenic factor (transforming growth factor [TGF]-beta). There was no significant difference in TGF-beta, IFN-gamma, IL-10, or IL-8 levels of expression according to liver-activity grade, liver-fibrosis stage, the concentration of HCV RNA at liver biopsies, or the HCV genotype. However, IFN-gamma/beta-actin mRNA concentration was higher than the IL-10/beta-actin mRNA concentration in patients with F3 Metavir score. Median IFN-gamma/beta-actin mRNA concentration tended to be higher in patients with A3 and A4 Metavir activity grades compared with those with A0 and A1 activity grades. There was a significant correlation between the duration of HCV infection and both TGF-beta/beta-actin (r(2)=0.19, P=0.04) and IL-8/beta-actin mRNA concentrations (r(2)=0.19, P=0.03). IFN-gamma/beta-actin mRNA concentration also increased according to the duration of HCV (r(2)=0.19, P=0.07). Finally, there was a significant correlation between the duration of HCV infection and liver fibrosis stage (r(2)=0.17, P=0.045). Intrahepatic Th1 cytokine profile seems to be predominant in patients with extensive fibrosis and activity scores, suggesting that it might be responsible for liver injury in renal transplant patients.

  18. Advantageous effects of immunosuppression with tacrolimus in comparison with cyclosporine A regarding renal function in patients after heart transplantation.

    Helmschrott, Matthias; Rivinius, Rasmus; Ruhparwar, Arjang; Schmack, Bastian; Erbel, Christian; Gleissner, Christian A; Akhavanpoor, Mohammadreza; Frankenstein, Lutz; Ehlermann, Philipp; Bruckner, Tom; Katus, Hugo A; Doesch, Andreas O


    Nephrotoxicity is a serious adverse effect of calcineurin inhibitor therapy in patients after heart transplantation (HTX). In this retrospective registry study, renal function within the first 2 years after HTX in patients receiving de novo calcineurin inhibitor treatment, that is, cyclosporine A (CSA) or tacrolimus (TAC), was analyzed. In a consecutive subgroup analysis, renal function in patients receiving conventional tacrolimus (CTAC) was compared with that of patients receiving extended-release tacrolimus (ETAC). Data from 150 HTX patients at Heidelberg Heart Transplantation Center were retrospectively analyzed. All patients were continuously receiving the primarily applied calcineurin inhibitor during the first 2 years after HTX and received follow-up care according to center practice. Within the first 2 years after HTX, serum creatinine increased significantly in patients receiving CSA (Prenal function in the first half year after HTX among patients receiving CSA (P=0.0004). In patients receiving TAC, no significant accumulation of patients with deterioration of renal function during the first 2 years after HTX was detectable (all P=ns). Direct comparison of patients receiving CTAC versus those receiving ETAC detected no significant differences regarding renal function between patients primarily receiving CTAC or ETAC treatment during study period (all P=ns). CSA is associated with a more pronounced deterioration of renal function, especially in the first 6 months after HTX, in comparison with patients receiving TAC as baseline immunosuppressive therapy.

    Many studies have been conducted showing that aminolevulinic acid (ALA)-photodynamic therapy (PDT) can be an alternative treatment for recalcitrant warts. Recently, we performed a study evaluating methyl-aminolevulinic acid (MAL)-PDT for the treatment of hand warts in a population of renal transplant patients. Two symmetrical targets were selected on each hand and randomly assigned to chemical keratolytic treatment followed by three cycles of ALA-PDT (75 J cm(-2) red light). Patients were evaluated after 3 months and a second run of PDT was performed if the total area and number of warts decreased less than 50%, with evaluation every 3 months for 1 year. Twenty patients were included and 16 were evaluable (9 M, 7 F). After 6 months the reduction of warts' area was 48.4% on the treated side versus 18.4% in the control area (P = 0.021). The decrease in the total number of warts was 41%versus 19.4% (P = NS). The global tolerance of the treatment was good with acceptable pain during irradiation. These results suggest that ALA-PDT is a safe and efficient treatment for transplanted patient warts. The improvement between treated and control zone is 20% due to the decrease in untreated warts' area and number. © 2012 Wiley Periodicals, Inc.

  2. Renal impairment after liver transplantation - a pilot trial of calcineurin inhibitor-free vs. calcineurin inhibitor sparing immunosuppression in patients with mildly impaired renal function after liver transplantation

    Gerhardt T


    Full Text Available Abstract Objectives Chronic kidney disease is frequent in patients after orthotopic liver transplantation (OLT and has impact on survival. Patients receiving calcineurin inhibitors (CNI are at increased risk to develop impaired renal function. Early CNI reduction and concomitant use of mycophenolat mofetil (MMF has been shown to improve renal function. Methods The aim of this trial was to compare dose-reduced CNI/MMF versus CNI-free MMF/prednisone-based treatment in stable patients after OLT with respect to glomerular filtration rate (GFR. 21 patients [GFR 44.9 ± 9.9 mL/min/1.73 m2 measured by 99m-Tc-DTPA-clearance, serum creatinine (SCr 1.5 ± 0.42 mg/dL] were randomized either to exchange CNI for 10 mg prednisone (group 1; n = 8 or to receive CNI at 25% of the initial dose (group 2; n = 13 each in combination with 1000 mg MMF b.i.d. Results At month 12 mean SCr (-0.3 ± 0.4 mg/dL, p = 0.031 and GFR improved (8.6 ± 13.1 mL/min/1.73 m2, p = 0.015 in group 2 but remained unchanged in group 1. Main side effects were gastroinstestinal symptoms (14.3% and infections (4.8%. Two biopsy proven, steroid-responsive rejections occurred. In group 1 mean diastolic blood pressure (BP increased by 11 ± 22 mmHg (p = 0.03. Conclusions Reduced dose CNI in combination with MMF but not CNI-free-immunosuppression leads to improvement of GFR in patients with moderately elevated SCr levels after OLT. Addition of steroids resulted in increased diastolic blood pressure presumably counterbalancing the benefits of CNI withdrawal on renal function.

  3. 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.

  4. Metabolic status of 1088 patients after renal transplantation: Assessment of twelve years monitoring in Algiers Mustapha Hospital

    Lyece Yargui


    Full Text Available Since the introduction of monitoring levels of immunosuppressive medications in our service in July 2000, 1088 kidney transplant patients were received for therapeutic drug monitoring and regular follow-up. The aim of this study was to retrospectively analyze the data on these renal graft patients in Algeria and correlate with our 12 years′ experience with calcineurin inhibitor (CNI measurements. In addition, during this period, we also examined other bioche-mical parameters. The analysis was focused on the difference of effect of cyclosporin A (CsA; 623 patients and Tacrolimus (Tac; 465 patients on lipid and glucose metabolism and their side-effects, if any, on the renal function. The mean age at the time of transplantation was 36.1 years. A great majority of the transplanted kidneys had been taken from living related donors (88.6%. Three-quarters of all grafts were transplanted in our country (79.5%. Dyslipidemia and renal dysfunction were the most common adverse effects of CsA and Tac exposure, with a frequency of 21.4% and 10.3%, respectively. Both the CNIs had a similar effect on the lipid levels. The highest incidence occurred at 3-12 months after renal graft. Tac seemed to have more side-effects on glycemia, causing the onset of diabetes mellitus more than two-fold than CsA (6.9% vs. 3.1%. A significant difference was observed during 12-24 months after transplantation. However, Tac was associated with the most favorable effects on renal function estimated with the Modification of Diet in Renal Disease (MDRD formula.

  5. 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.

  6. 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.

    Park, Hye Seong; Kim, Hak Hee; Choi, Yeong Jin; Kim, Young Ok; Shinn, Kyung Sub [Catholic Univ., Seoul (Korea, Republic of). Coll. of Medicine


    Kaposi`s sarcoma accounts for more than 3% of neoplasms occurring in patients who have undergone a transplant. An epidemiologic study showed that in renal transplanted patients, the incidence of Kaposi`s sarcoma was 400 to 500 times higher than in controls of the same ethnic origin. We report a case of Kaposi`s sarcoma involving the lung and skin after immunosuppressive therapy in a patient with renal transplant. A plain chest radiograph showed diffusely increased interstital opacity with multiple, ill-defined small nodules in both lung fields. HRCT revealed multiple small nodules, predominantly in the peribronchovascular regions, and ill-defined areas of ground-glass opacity and consolidation in both lungs. (author). 10 refs., 1 fig.

  8. Functional G1199A ABCB1 polymorphism may have an effect on cyclosporine blood concentration in renal transplanted patients.

    Cyclosporine A (CsA) shows significant inter-individual variability in its pharmacokinetics, which may be due to polymorphisms in ABCB-1 genes coding for P-glycoprotein. The aim of this study was to explore the role of genetic polymorphisms of ABCB-1 in affecting the CsA blood concentrations in renal transplanted patients over the first 3 months after transplantation. Renal transplanted patients receiving CsA (n = 40) were genotyped for ABCB -1 C3435T (I1145I) and G1199A (S400N) polymorphisms. CsA blood concentrations were measured on Day 7, 30, and 90 after transplantation. G1199A variant showed higher CsA blood concentrations in stable patients, that was significant for trough levels (198 vs. 136 ng/mL on Day 7, P = .004, 196 vs. 125 ng/mL on Day 30, P = .007, 194 vs. 121 ng/mL on Day 90, P = .005 for stable vs. unstable groups). Polymorphisms of ABCB-1 have only a minor effect on CsA blood concentrations. The functional G1199A polymorphism can affect the drug levels more than non-functional C3435T. This polymorphism might be of a potential prognostic value in renal transplanted patients. © The Author(s) 2013.

  9. Intraoperative Diagnosis of Stanford Type A Dissection by Transesophageal Echocardiogram in a Patient Presenting for Renal Transplantation

    William R. Hand


    Full Text Available A 48-year-old patient with hypertensive end-stage renal disease presented for cadaveric renal transplantation. On physical exam, a previously undocumented diastolic murmur was heard loudest at the left lower sternal border. The patient had a history of pericardial effusions and reported “a feeling of chest fullness” when lying flat. As such, a transesophageal echocardiogram (TEE was performed after induction of anesthesia to evaluate the pericardial space and possibly determine the etiology and severity of the new murmur. The TEE revealed a Stanford Type A aortic dissection. The renal transplant was cancelled (organ reassigned within region, and the patient underwent an urgent ascending and proximal hemiarch aortic replacement. This case demonstrates the importance of a thorough physical exam and highlights the utility of TEE for noncardiac surgical cases.

  10. 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.

    Scheel, Jennifer; Reber, Sandra; Stoessel, Lisa; Waldmann, Elisabeth; Jank, Sabine; Eckardt, Kai-Uwe; Grundmann, Franziska; Vitinius, Frank; de Zwaan, Martina; Bertram, Anna; Erim, Yesim


    Different measures of non-adherence to immunosuppressant (IS) medication have been found to be associated with rejection episodes after successful transplantation. The aim of the current study was to investigate whether graft rejection after renal transplantation is associated with patient-reported IS medication non-adherence and IS trough level variables (IS trough level variability and percentage of sub-therapeutic IS trough levels). Patient-reported non-adherence, IS trough level variability, percentage of sub-therapeutic IS trough levels, and acute biopsy-proven late allograft rejections were assessed in 267 adult renal transplant recipients who were ≥12 months post-transplantation. The rate of rejection was 13.5%. IS trough level variability, percentage of sub-therapeutic IS trough levels as well as patient-reported non-adherence were all significantly and positively associated with rejection, but not with each other. Logistic regression analyses revealed that only the percentage of sub-therapeutic IS trough levels and age at transplantation remained significantly associated with rejection. Particularly, the percentage of sub-therapeutic IS trough levels is associated with acute rejections after kidney transplantation whereas IS trough level variability and patient-reported non-adherence seem to be of subordinate importance. Patient-reported non-adherence and IS trough level variables were not correlated; thus, non-adherence should always be measured in a multi-methodological approach. Further research concerning the best combination of non-adherence measures is needed.

  12. Successful Treatment of Recurrent Pulmonary Mucormycosis in a Renal Transplant Patient: A Case Report and Literature Review

    Martin, Morgan S.; Lobo, Monica


    Background. We describe the unusual case of a recently transplanted cadaveric renal transplant recipient who presented with recurrent pulmonary mucormycosis. Case Report. An 18-year-old man with end stage renal disease secondary to congenital renal agenesis status after cadaveric kidney transplant 4 months before presented with acute onset of fever, hemoptysis, and back pain. The patient underwent an emergent left lower lobectomy due to the critical nature of his illness. He was also treated with amphotericin with resolution of his symptoms. One week later, he had evidence of recurrent disease on imaging with a surgical site infection. He underwent reexploration with evacuation of an empyema and debridement of a surgical site infection. He was continued on IV antifungal therapy with isavuconazonium and amphotericin. Radiographic clearance of disease with three months of treatment was apparent with no evidence of recurrence at seven-month follow-up. Discussion. Opportunistic infections in solid organ transplant patients represent a significant source of morbidity and mortality. Most patients are treated with prophylactic anti-infective agents. However, rare infections such as pulmonary mucormycosis remain a risk. The transplant physician must be aware of these uncommon infections and their treatment strategies, including the management of uncommon recurrent disease.

  14. The use of personalized medicine for patient selection for renal transplantation: Physicians' views on the clinical and ethical implications

    Doucet Hubert


    Full Text Available Abstract Background The overwhelming scarcity of organs within renal transplantation forces researchers and transplantation teams to seek new ways to increase efficacy. One of the possibilities is the use of personalized medicine, an approach based on quantifiable and scientific factors that determine the global immunological risk of rejection for each patient. Although this approach can improve the efficacy of transplantations, it also poses a number of ethical questions. Methods The qualitative research involved 22 semi-structured interviews with nephrologists involved in renal transplantation, with the goal of determining the professionals' views about calculating the global immunological risk and the attendant ethical issues. Results The results demonstrate a general acceptance of this approach amongst the participants in the study. Knowledge of each patient's immunological risk could improve treatment and the post-graft follow-up. On the other hand, the possibility that patients might be excluded from transplantation poses a significant ethical issue. This approach is not seen as something entirely new, given the fact that medicine is increasingly scientific and evidence-based. Although renal transplantation incorporates scientific data, these physicians believe that there should always be a place for clinical judgment and the physician-patient relationship. Conclusions The participants see the benefits of including the calculation of the global immunological risk within transplantation. Such data, being more precise and rigorous, could be of help in their clinical work. However, in spite of the use of such scientific data, a place must be retained for the clinical judgment that allows a physician to make decisions based on medical data, professional expertise and knowledge of the patient. To act in the best interests of the patient is key to whether the calculation of the global immunological risk is employed.

  15. 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 

  16. Interferon-free regimens in patients with hepatitis C infection and renal dysfunction or kidney transplantation

    Cholongitas, Evangelos; Pipili, Chrysoula; Papatheodoridis, George V


    Treatment of patients with chronic kidney disease (CKD) and chronic hepatitis C (CHC) differs from that used in the general CHC population mostly when glomerular filtration rate (GFR) is below 30 mL/min, as sofosbuvir, the backbone of several current regimens, is officially contraindicated. Given that ribavirin free regimens are preferable in CKD, elbasvir/grazoprevir is offered in CHC patients with genotype 1 or 4 and ombitasvir/paritaprevir and dasabuvir in genotype 1b for 12 wk. Although regimens containing peginterferon with or without ribavirin are officially recommended for patients with CKD and genotype 2, 3, 5, 6, such regimens are rarely used because of their low efficacy and the poor safety and tolerance profile. In this setting, especially in the presence of advanced liver disease, sofosbuvir-based regimens are often used, despite sofosbuvir contraindication. It seems to have good overall safety with only 6% or 3.4% of CKD patients to discontinue therapy or develop serious adverse events without drug discontinuation. In addition, sustained virological response (SVR) rates with sofosbuvir based regimens in CKD patients appear to be comparable with SVR rates in patients with normal renal function. Treatment recommendations for kidney transplant recipients are the same with those for patients with CHC, taking into consideration potential drug-drug interactions and baseline GFR before treatment initiation. This review summarizes recent data on the current management of CHC in CKD patients highlighting their strengths and weaknesses and determining their usefulness in clinical practice. PMID:28217256

  17. Barriers and strategies for taking medicines in adult patients with renal transplantation.

    Cedillo-Galindo, H; Gracida, C


    Adherence to the immunosuppressant medications is important for the proper function a renal graft, but there are factors that make this difficult. This study describes strategies and barriers to adequate intake of these medicines based upon 177 surveys in renal transplant patients. Medication adherence was reported to be high (84%), but there were barriers to taking medications (64.95%): the most common were that the pharmacy did not work medicines (28.81%), changes in medication or dose (24.29%), failure to remember (9.6%), and lack of time (6.78%). The most common strategies for taking medications were: the use of cell phone alarms (15.25%) or alarm clocks (9.04%), schedules (5.65%), drug-related meals (5.08%), drug use book (2.26%), and visibility on the table (2.26%). Proper understanding of the barriers to medication adherence and strategies used by recipients may help physicians more adequately educate patients, thereby reducing the risk of rejection related to nonadherence and suggest, specific interventions for improvement.

  18. Tuberculosis in renal transplant patients: The experience of a single center in Medellín-Colombia, 2005-2013

    Lina Maria Serna Higuita


    Full Text Available Introduction: Tuberculosis is a common opportunistic infection in renal transplant patients. Objective: To obtain a clinical and laboratory description of transplant patients diagnosed with tuberculosis and their response to treatment during a period ranging from 2005 to 2013 at the Pablo Tobón Uribe Hospital. Methods: Retrospective and descriptive study. Results: In 641 renal transplants, tuberculosis was confirmed in 12 cases. Of these, 25% had a history of acute rejection, and 50% had creatinine levels greater than 1.5 mg/dl prior to infection. The disease typically presented as pulmonary (50% and disseminated (33.3%. The first phase of treatment consisted of 3 months of HZRE (isoniazid, pyrazinamide, rifampicin and ethambutol in 75% of the cases and HZME (isoniazid, pyrazinamide, moxifloxacin and ethambutol in 25% of the cases. During the second phase of the treatment, 75% of the cases received isoniazid and rifampicin, and 25% of the cases received isoniazid and ethambutol. The length of treatment varied between 6 and 18 months. In 41.7% of patients, hepatotoxicity was associated with the beginning of anti-tuberculosis therapy. During a year-long follow-up, renal function remained stable, and the mortality rate was 16.7%. Conclusion: Tuberculosis in the renal transplant population studied caused diverse nonspecific symptoms. Pulmonary and disseminated tuberculosis were the most frequent forms and required prolonged treatment. Antituberculosis medications had a high toxicity and mortality. This infection must be considered when patients present with a febrile syndrome of unknown origin, especially during the first year after renal transplant.

  19. Anaesthetic Management of Renal Transplant Surgery in Patients of Dilated Cardiomyopathy with Ejection Fraction Less Than 40%

    Divya Srivastava


    Full Text Available Cardiovascular disease (CVD is an important comorbidity of chronic kidney disease, and reducing cardiovascular events in this population is an important goal for the clinicians who care for chronic kidney disease patients. The high risk for CVD in transplant recipients is in part explained by the high prevalence of conventional CVD risk factors (e.g., diabetes, hypertension, and dyslipidemia in this patient population. Current transplant success allows recipients with previous contraindications to transplant to have access to this procedure with more frequency and safety. Herein we provide a series of eight patients with dilated cardiomyopathy with poor ejection fraction posted for live donor renal transplantation which was successfully performed under regional anesthesia with sedation.

  20. Formal quality improvement curriculum and DMAIC method results in interdisciplinary collaboration and process improvement in renal transplant patients.

    Leaphart, Cynthia L; Gonwa, Thomas A; Mai, Martin L; Prendergast, Mary B; Wadei, Hani M; Tepas, Joseph J; Taner, C Burcin


    Broad-based formal quality improvement curriculum emphasizing Six Sigma and the DMAIC approach developed by our institution is required for physicians in training. DMAIC methods evaluated the common outcome of postoperative hyponatremia, thus resulting in collaboration to prevent hyponatremia in the renal transplant population. To define postoperative hyponatremia in renal transplant recipients, a project charter outlined project aims. To measure postoperative hyponatremia, serum sodium at admission and immediately postoperative were recorded by retrospective review of renal transplant recipient charts from June 29, 2010 to December 31, 2011. An Ishikawa diagram was generated to analyze potential causative factors. Interdisciplinary collaboration and hospital policy assessment determined necessary improvements to prevent hyponatremia. Continuous monitoring in control phase was performed by establishing the goal of <10% of transplant recipients with abnormal serum sodium annually through quarterly reduction of hyponatremia by 30% to reach this goal. Of 54 transplant recipients, postoperative hyponatremia occurred in 92.6% of patients. These potential causes were evaluated: 1) Hemodialysis was more common than peritoneal dialysis. 2) Alemtuzumab induction was more common than antithymocyte globulin. 3) A primary diagnosis of diabetes existed in 16 patients (30%). 4) Strikingly, 51 patients received 0.45% sodium chloride intraoperatively, suggesting this as the most likely cause of postoperative hyponatremia. A hospital policy change to administer 0.9% sodium chloride during renal transplantation resulted in normal serum sodium levels postoperatively in 59 of 64 patients (92.2%). The DMAIC approach and formal quality curriculum for trainees addresses core competencies by providing a framework for problem solving, interdisciplinary collaboration, and process improvement.

  1. Helicobacter cinaedi bacteremia in four renal transplant patients: clinical features and an important suggestion regarding the route of infection.

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


    Helicobacter cinaedi can cause bacteremia mainly in immunocompromised patients. We present the clinical characteristics of H. cinaedi bacteremia in 4 renal transplant patients. Interestingly, all cases showed triggers of bacterial translocation: 2 cases developed after colonic perforation caused by diverticulitis, 1 case developed post cholecystectomy, and the remaining patient had chronic diarrhea. Accordingly, bacterial translocation caused by severe gastrointestinal complication could be a cause of H. cinaedi bacteremia.

  2. 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.

    Using reduced doses of Cyclosporine A immediately after heart transplantation in clinical trials may suggest benefits for renal function by reducing serum creatinine levels without a significant change in clinical endpoints. However, these trials were not sufficiently powered to prove clinical outcomes. In a prospective, multicentre, open-label, parallel-group controlled trial, 95 patients aged 18 to 65 years old, undergoing de novo heart transplantation were centrally randomised to receive either a low (130 Cyclosporine A (200 transplant months along with mycophenolate mofetil and corticosteroids. Participants had a stable haemodynamic status, a serum creatinine level transplants were excluded. The change in serum creatinine level over 12 months was used as the main criterion for renal function. Intention-to-treat analysis was performed on the 95 randomised patients and a mixed generalised linear model of covariance was applied. At 12 months, the mean (± SD) creatinine value was 120.7 μmol/L (± 35.8) in the low-dose group and 132.3 μmol/L (± 49.1) in the standard-dose group (P = 0.162). Post hoc analyses suggested that patients with higher creatinine levels at baseline benefited significantly from the lower Cyclosporine A target. The number of patients with at least one rejection episode was not significantly different but one patient in the low-dose group and six in the standard-dose group required dialysis. In patients with de novo cardiac transplantation, early Cyclosporine A dose reduction was not associated with renal benefit at 12 months. However, the strategy may benefit patients with high creatinine levels before transplantation. NCT00159159.

    Full Text Available Matthias Helmschrott,1 Rasmus Rivinius,1 Thomas Bruckner,2 Hugo A Katus,1 Andreas O Doesch1 1Department of Cardiology, Angiology, Pneumology, 2Institute for Medical Biometry and Informatics, University of Heidelberg, Heidelberg, Germany Background: A calcineurin inhibitor (CNI-based immunosuppression combined with mammalian target of rapamycin inhibitors (mTORs seems to be attractive in patients after heart transplantation (HTX in special clinical situations, for example, in patients with adverse drug effects of prior immunosuppression. Previous studies in patients after HTX detected advantageous effects regarding renal function of a tacrolimus (TAC-based vs cyclosporine-A (CSA-based immunosuppression (in combination with mycophenolate mofetil. However, data regarding renal function after HTX in mTOR/CNI patients remain limited. Aim: Primary end point of the present study was to analyze renal function in HTX patients 1 year after switch to an mTOR/CNI-based immunosuppression. Methods: Data of 80 HTX patients after change to mTOR/CNI-based immunosuppression were retrospectively analyzed. Renal function was assessed by measured serum creatinine and by estimated glomerular filtration rate (eGFR calculated from Modification of Diet in Renal Disease equation. Results: Twenty-nine patients received mTOR/CSA-based treatment and 51 patients received mTOR/TAC-based therapy. At time of switch and at 1-year follow-up, serum creatinine and eGFR did not differ significantly between both study groups (all P=not statistically significant. Analysis of variances with repeated measurements detected a similar change of renal function in both study groups. Conclusion: The present study detected no significant differences between both mTOR/CNI study groups, indicating a steady state of renal function in HTX patients after switch of immunosuppressive regimen.

  5. 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.

  6. Renal transplantation experience in a patient with factor V Leiden homozygous, MTHFR C677T heterozygous, and PAI heterozygous mutation.

    Gülhan, Bora; Tavil, Betül; Gümrük, Fatma; Aki, Tuncay F; Topaloglu, Rezan


    Vascular complications are important causes of allograft loss in renal transplantation. A two and a half-month-old boy was diagnosed with posterior urethral valve and progressed to end-stage renal disease at eight yr of age. During the HD period, a central venous catheter was replaced three times for repeated thrombosis. The boy was found to be homozygous for FVL and heterozygous for both MTHFR (C677T) and PAI. At the age of 12, renal transplantation was performed from a deceased donor. Postoperative anticoagulation therapy was initiated with continuous intravenous administration of heparin at the dose of 10 IU/kg/h. HD was performed for the first three days. By the fourth day of transplantation, his urine output had increased gradually. Heparin infusion was continued for 18 days during hospitalization at the same dosage. Thereafter, he was discharged with LMWH. On the third month after transplantation, his serum creatinine level was 1.1 mg/dL and eGFR was 75.7 mL/min/1.73 m(2). He has still been using LMWH, and his eGFR was 78.7 mL/min/1.73 m(2) eight months after transplantation. Postoperative low-dose heparin treatment is a safe strategy for managing a patient with multiple thrombotic risk factors. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  7. 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.

  8. Cutaneous fungal infection in a renal transplantation patient due to a rare fungus belonging to order Pleosporales

    S Galipothu


    Full Text Available Fungal infections are being increasingly reported from immuno-compromised as well as immuno-competent patients. Transplant patients are on long term immunosuppressive therapy which makes them highly vulnerable to opportunistic fungal infections .These infections can be cutaneous or systemic. Several fungi have been reported to be the culprits such as Candida spp., Aspergillus spp., C. neoformans, P. carinii, and zygomycetes group of fungi. Cutaneous infections are most commonly caused by Pityriasis (tinea versicolor, dermatophytes, and candida sp but these days the demtiaceous fungi are becoming more frequently reported .Here we report a case of post renal transplant cutaneous infection caused by dematiaceous fungus belonging to the order Pleosporales

  9. [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.

  10. 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.

  11. Aberrant DNA methylation associated with MTHFR C677T genetic polymorphism in cutaneous squamous cell carcinoma in renal transplant patients.

    Laing, M E


    Changes in genomic DNA methylation associated with cancer include global DNA hypomethylation and gene-specific hyper- or hypomethylation. We have previously identified a genetic variant in the MTHFR gene involved in the methylation pathway which confers risk for the development of squamous cell carcinoma (SCC) in renal transplant patients. This genetic variant has also been discovered to confer SCC risk in nontransplant patients with low folate status.

  12. Pregnancy outcome in renal transplant recipients.

    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.

  13. 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.

  14. 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.

  15. Gingival overgrowth among patients medicated with cyclosporin A and tacrolimus undergoing renal transplantation: a prospective study.

    Paixão, Caroline G; Sekiguchi, Ricardo T; Saraiva, Luciana; Pannuti, Cláudio M; Silva, Hélio T; Medina-Pestana, José O; Romito, Giuseppe A


    The aim of this study is to make a longitudinal evaluation of the incidence and severity of gingival overgrowth (GO) induced by immunosuppressive agents, such as tacrolimus (Tcr) and cyclosporin A (CsA), in the absence of calcium channel blockers in patients undergoing renal transplantation (RT). This longitudinal study is conducted in 49 patients with RT who were divided into a CsA group (n = 25) and Tcr group (n = 24). The individuals were assessed at four time intervals: before transplant and 30, 90, and 180 days after RTs. Demographic data and periodontal clinical parameters (plaque index, cemento-enamel junction to the gingival margin, probing depth, clinical attachment level, bleeding on probing [BOP], and GO) were collected at all time intervals. The mean GO index was significantly lower in the Tcr group compared to the CsA group after 30 (P = 0.03), 90 (P = 0.004), and 180 (P = 0.01) days of immunosuppressive therapy. One hundred eighty days after RTs, a clinically significant GO was observed in 20.0% of individuals in the CsA group and 8.3% of individuals in the Tcr group. However, this difference was not statistically significant (P = 0.41). There was a reduction in periodontal clinical parameters regarding the time of immunosuppressive therapy for PI and BOP (P <0.001) in both groups. Although there was no statistical difference in the incidences of clinically significant GO after 180 days of immunosuppressive therapy, it was observed that GO occurred later in the Tcr group, and the severity of GO in this group was lower than in patients who used CsA.

  16. 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.

  17. 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....

  18. Cerebral Post-Transplant Lymphoproliferative Disorder Occurring after Renal Transplantation: A Case Report

    Suh, Jang Ho; Byun, Woo Mok; Kim, Hong Chul; Hwang, Min Su [Dept. of Radiology, Yeungnam University College of Medicine, Daegu (Korea, Republic of)


    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

  20. Study of the risk factors related to acquisition of urinary tract infections in patients submitted to renal transplant

    Mayra Gonçalves Menegueti


    Full Text Available INTRODUCTION: Urinary tract infections (UTI among transplant recipients are usually caused by gram-negative microorganisms and can provoke a high incidence of morbidity and mortality. The aim of this study was to evaluate the risk factors associated with the acquisition of UTIs during the first year after renal transplantation. METHODS: Here, we report a single-center retrospective cohort study of 99 renal transplant patients followed for the first year after surgery. The definition of a UTI episode was a urine culture showing bacterial growth and leucocyturia when patients presented with urinary symptoms. The absence of infection (asymptomatic bacteriuria was defined as an absence of symptoms with negative urine culture or bacterial growth with any number of colonies. RESULTS: Ninety-nine patients were included in the study. During the study, 1,847 urine cultures were collected, and 320 (17.3% tested positive for bacterial growth. Twenty-six (26.2% patients developed a UTI. The most frequent microorganisms isolated from patients with UTIs were Klebsiella pneumoniae (36%, with 33% of the strains resistant to carbapenems, followed by Escherichia coli (20%. There were no deaths or graft losses associated with UTI episodes. CONCLUSIONS: Among the UTI risk factors studied, the only one that was associated with a higher incidence of infection was female sex. Moreover, the identification of drug-resistant strains is worrisome, as these infections have become widespread globally and represent a challenge in the control and management of infections, especially in solid organ 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 ter

  3. 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.

  4. Human papillomavirus-related verrucous carcinoma in a renal transplant patient after long-term immunosuppression: a case report.

    Imko-Walczuk, B; Cegielska, A; Placek, W; Kaszewski, Sebastian; Fiedor, P


    Verrucous carcinoma is a slow-growing tumor with 3 main localizations: Oral cavity, ano-urogenital region, and plantar surface of the foot. On the sole it may rise adjacent to viral warts and very often is mistaken for the common verruca plantaris. Although both conditions-viral warts and cutaneous squamous cell carcinoma-are often diagnosed in immunosuppressed patients, in literature we have found only 3 case reports of verrucous carcinoma in organ transplant recipients. We present a case of 26-year-old man after deceased donor renal transplantation with plantar verrucous carcinoma successfully treated with excision and 5% imiquimod.

    NIE Xin-min; GUI Rong; ZHAO Hong-shan; MA Da-long; LI Deng-qing; YUAN Hong; HUANG Zu-fa


    Objective Tacrolimus is an immunosuppressive drug with narrow therapeutic range and wide interindividual variation in its pharmacokinetics. Tacrolimus is a substrate of cytochrome P450(CYP)3A5. The aim of this study was to evaluate whether the A6986G polymorphism is associated with tacrolimus concentration/dose ratio.Methods Fifty-two Chinese renal transplant patients were enrolled in this study. Their body weight, dosage and concentration of tacrolimus were observed. CYP3A5 genotype was determined by polymerase chain reaction followed by restriction fragment length polymorphism analysis. Results A significant association was found between tacrolimus levels per dose/kg/d and CYP3A5 gene A6986G polymorphism(P<0.001). The CYP3A5 * 3 * 3 patients have a significantly higher tacrolimus level/dose than CYP3A5 * 1 * 1 and CYP3A5 * 1 * 3. Conclusions CYP3A5 gene A6986G polymorphism is associated with tacrolimus pharmacokinetics and dose requirements. Pharmacogenetic methods could be employed prospectively to help the dose selection and to individualize immunosuppressive therapy according to the result.

  6. 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.

  7. [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.

  9. Down regulation of TRAIL and FasL on NK cells by Cyclosporin A in renal transplantation patients.

    Zhang, Yun; Cheng, Guang; Xu, Zhu-Wei; Li, Zhou-Li; Song, Chao-Jun; Li, Qi; Chen, Li-Hua; Yang, Kun; Yang, An-Gang; Jin, Bo-Quan


    TNF-related apoptosis-inducing ligand (TRAIL) and FasL can participate in cell mediated cytotoxicity via their death domain-mediated apoptotic signaling in the host-versus-graft disease occurred after renal transplantation. However, the effect of Cyclosporin A (CsA) commonly used as a drug to prevent and to treat renal transplant rejection, on these molecules have not been fully determined. In the present study, we found that with CsA administration, the expression of TRAIL and FasL predominantly on NK cells from renal transplantation patients was increased at day 5 after operation and went down to normal level on day 13. While, the levels of soluble TRAIL (sTRAIL) and sFasL in the serum increased within 25 days and went down to normal level three month later. In addition, we showed that a remarkable increase of TRAIL and FasL expression both on the surface of activated lymphocytes especially on NK cells and in the supernatants generated from mixed lymphocytes culture (MLC). Furthermore, the enhancement of these two molecules was greatly decreased by adding 500 ng/mL CsA at the beginning of MLC. We conclude that CsA may inhibit the transplant rejection partially by down-regulating the expression of TRAIL and FasL on NK cells. Copyright © 2013 Elsevier B.V. All rights reserved.

  10. Astaxanthin vs placebo on arterial stiffness, oxidative stress and inflammation in renal transplant patients (Xanthin: a randomised controlled trial

    Robertson Iain K


    Full Text Available Abstract Background There is evidence that renal transplant recipients have accelerated atherosclerosis manifest by increased cardiovascular morbidity and mortality. The high incidence of atherosclerosis is, in part, related to increased arterial stiffness, vascular dysfunction, elevated oxidative stress and inflammation associated with immunosuppressive therapy. The dietary supplement astaxanthin has shown promise as an antioxidant and anti-inflammatory therapeutic agent in cardiovascular disease. The aim of this trial is to investigate the effects of astaxanthin supplementation on arterial stiffness, oxidative stress and inflammation in renal transplant patients. Method and Design This is a randomised, placebo controlled clinical trial. A total of 66 renal transplant recipients will be enrolled and allocated to receive either 12 mg/day of astaxanthin or an identical placebo for one-year. Patients will be stratified into four groups according to the type of immunosuppressant therapy they receive: 1 cyclosporine, 2 sirolimus, 3 tacrolimus or 4 prednisolone+/-azathioprine, mycophenolate mofetil or mycophenolate sodium. Primary outcome measures will be changes in 1 arterial stiffness measured by aortic pulse wave velocity (PWV, 2 oxidative stress assessed by plasma isoprostanes and 3 inflammation by plasma pentraxin 3. Secondary outcomes will include changes in vascular function assessed using the brachial artery reactivity (BAR technique, carotid artery intimal medial thickness (CIMT, augmentation index (AIx, left ventricular afterload and additional measures of oxidative stress and inflammation. Patients will undergo these measures at baseline, six and 12 months. Discussion The results of this study will help determine the efficacy of astaxanthin on vascular structure, oxidative stress and inflammation in renal transplant patients. This may lead to a larger intervention trial assessing cardiovascular morbidity and mortality. Trial Registration

  11. [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.

  12. Impact of everolimus: update on immunosuppressive therapy strategies and patient outcomes after renal transplantation

    Helio Tedesco-Silva Jr


    , mainly to preserve renal function and to manage patients with malignancy. There is no definition of the ideal strategy for conversion, ie, abrupt or sequential, initial dose of everolimus, or target therapeutic trough blood concentrations. Intensive monitoring is recommended after conversion, especially for acute rejection and proteinuria. Because mTOR is ubiquitous and central to many intracellular processes, an array of adverse reactions may occur, including delayed tissue regeneration, proteinuria, dyslipidemia, diabetes, myelosuppression, infertility, ovarian cysts, and mouth ulcers. Because long-term benefits are the goal of any immunosuppressive strategy, further investigations aiming to understand, prevent, and manage everolimus-related adverse reactions are necessary to mitigate the risks and improve tolerability, allowing maximization of all the benefits of this drug.Keywords: everolimus, immunosuppression, mTOR inhibitors, calcineurin inhibitors, kidney transplantation

  14. Mycophenolate mofetil in low-risk renal transplantation in patients receiving no cyclosporine: a single-centre experience.

    Raheem, Omer A


    BACKGROUND: We assess our long-term experience with regards the safety and efficacy of Mycophenolate Mofetil (MMF) in our low risk renal transplant population and compared it retrospectively to Azathioprine (AZA) immunosuppressive regimen. Patients and methods. Between January 1999 and December 2005, 240 renal transplants received MMF as part of their immunosuppressive protocol (MMF group). AZA group of 135 renal transplants was included for comparative analysis (AZA group). Patients received Cyclosporine was excluded from this study. RESULTS: The incidence of biopsy proven 3-month acute rejections was 30 (12.5%) in MMF group and 22 (16%) in AZA group respectively (P = 0.307). Patient survival rates at 1 and 5 years for the MMF group were 97 and 94%, respectively, compared to 100% and 91% at 1 and 5 years respectively for the AZA group (P = 0.61). Graft survival rates at 1 and 5 years for the MMF group were 95 and 83%, respectively, compared to 97 and 84% at 1 and 5 years, respectively for the AZA group (P = 0.62). CONCLUSION: There was no difference in acute rejection episodes between MMF and AZA based immunotherapy. Additionally, we observed no significant difference concerning graft survival in the MMF group when compared to AZA group.

  17. 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.

    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. 

  19. Lack of benefit of early protocol biopsies in renal transplant patients receiving TAC and MMF: a randomized study.

    Rush, D; Arlen, D; Boucher, A; Busque, S; Cockfield, S M; Girardin, C; Knoll, G; Lachance, J-G; Landsberg, D; Shapiro, J; Shoker, A; Yilmaz, S


    We conducted a randomized, multicenter study to determine whether treatment of subclinical rejection with increased corticosteroids resulted in beneficial outcomes in renal transplant patients receiving tacrolimus (TAC), mycophenolate mofetil (MMF) and prednisone. One hundred and twenty-one patients were randomized to biopsies at 0,1,2,3 and 6 months (Biopsy arm), and 119 to biopsies at 0 and 6 months only (Control arm). The primary endpoint of the study was the prevalence of the sum of the interstitial and tubular scores (ci + ct)> 2 (Banff) at 6 months. Secondary endpoints included clinical and subclinical rejection and renal function. At 6 months, 34.8% of the Biopsy and 20.5% of the Control arm patients had a ci + ct score >or= 2 (p = 0.07). Between months 0 and 6, clinical rejection episodes were 12 in 10 Biopsy arm patients and 8 in 8 Control arm patients (p = 0.44). Overall prevalence of subclinical rejection in the Biopsy arm was 4.6%. Creatinine clearance at 6 months was 72.9 +/- 21.7 in the Biopsy and 68.90 mL/min +/- 18.35 mL/min in the Control arm patients (p = 0.18). In conclusion, we found no benefit to the procurement of early protocol biopsies in renal transplant patients receiving TAC, MMF and prednisone, at least in the short term. This is likely due to their low prevalence of subclinical rejection.

  20. Thallium stress testing does not predict cardiovascular risk in diabetic patients with end-stage renal disease undergoing cadaveric renal transplantation

    Holley, J.L.; Fenton, R.A.; Arthur, R.S. (Univ. of Pittsburgh, PA (USA))


    This study assessed the usefulness of thallium stress testing as a predictor of perioperative cardiovascular risk in diabetic patients with end-stage renal disease undergoing cadaveric renal transplantation. Demographic factors influencing the exercise performance in these patients were also examined. The medical records of 189 consecutive patients with diabetic nephropathy who were evaluated for cadaveric renal transplantation were reviewed. Thallium stress testing was the initial examination of cardiovascular status in 141 patients. An adequate examination was one in which at least 70% of maximum heart rate was achieved. A thallium stress test was normal if there were no ST segment depressions on the electrocardiogram and no perfusion abnormalities on the thallium scan. Forty-four patients underwent cardiac catheterization as the initial evaluation (Group C) and four patients underwent transplantation without a formal cardiovascular evaluation (Group D). Sixty-four of the 141 patients undergoing thallium stress testing had an adequate and normal examination (Group A). The incidence of perioperative cardiac events in this group was 2%. Seventy-seven patients (Group B) had an abnormal (n = 41) or an inadequate (n = 36) thallium stress test and most (n = 61) then underwent coronary angiography. The use of beta-blockers was the only predictor of an abnormal or inadequate thallium stress test. Forty-three percent of patients with inadequate or abnormal thallium stress tests had significant coronary artery disease on cardiac catheterization. The perioperative risk of cardiac events was not different in Group A versus Groups B, C, and D combined. Survival of Group A and B patients was not different but was significantly longer than that of Group C patients.

  1. 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...

  2. [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.

  3. 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.

  4. 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

  5. HBsAg as predictor of outcome in renal transplant patients HBsAg como predictor de evolución en trasplantados renales

    Ezequiel Ridruejo


    Full Text Available Chronic liver infections related to hepatitis B and C viruses are a common problem in renal transplant patients with a prevalence of 1.5 to 50% in different countries. There is no uniform agreement regarding their influence on the incidence of acute rejection, graft outcome and survival of renal transplant patients. We retrospectively evaluated the influence of antiHBc, antiHCV and HBsAg positive status; gender; age over 50 years of age at the time of transplantation; pre and postransplantation alaninaminotransferase (ALT elevation; acute rejection; type of graft; number of transplants; and maintenance and induction immunosuppression treatment on the incidence of acute rejection and both graft and patient survival in the population transplanted in our center between 1991 and 1998. The univariate analysis showed that antiHCV, HBsAg and antiHBc status, more than one renal transplant and one or more episodes of acute rejection were associated with diminished graft survival; and being over the age of 50 at the time of transplantation was also associated with diminished patient survival. In the multivariate analysis HBsAg positive and one or more episodes of rejection were associated with a diminished graft survival, and none of the variables studied was associated with diminished patient survival. In conclusion antiHCV and HBsAg positive status was associated with an increased risk of losing the transplanted kidney, and HBsAg positivity was associated with an increased risk of death, but this was not a statistically significant association.Las hepatitis virales crónicas causadas por los virus B y C son un problema común en los pacientes trasplantados renales. No hay un consenso en cuanto a su influencia en la evolución del injerto y la sobrevida de los pacientes trasplantados renales. Evaluamos en forma retrospectiva la influencia de la positividad de antiHBc, antiHCV y HBsAg; sexo; edad mayor de 50 años al momento del trasplante; elevación de

  6. Once-daily oral administration of cyclosporine in a lung transplant patient with a history of renal toxicity of calcineurin inhibitors.

    Matsuda, Yuya; Chen, Fengshi; Miyata, Hitomi; Date, Hiroshi


    Cyclosporine is usually administered orally in two divided doses every 12 h in transplant patients. However, some patients have difficulty in achieving therapeutic levels after transplantation. In fact, cyclosporine is reportedly administered once daily in renal and liver transplantation cases, but not in lung transplantation cases. We report a patient with a history of calcineurin inhibitor-induced renal toxicity who successfully underwent living-donor lobar lung transplantation (LDLLT) with the novel immunosuppressive strategy of once-daily administration of cyclosporine. An 18-year old man with progressive respiratory insufficiency after bone marrow transplantation was referred to our hospital for lung transplantation. He had a history of renal toxicity due to calcineurin inhibitors. Based on his history of tacrolimus- and cyclosporine-induced renal toxicity, we decided to initiate basiliximab as induction therapy, followed by once-daily cyclosporine administration to obtain high enough blood cyclosporine concentrations at 2 h post-dose (C2) and lowered trough blood concentrations (C0) for protection of renal function as maintenance therapy. LDLLT was successfully performed, and the postoperative course was uneventful and free of rejection episodes. Cyclosporine dosing was adjusted with intensive therapeutic drug monitoring of blood cyclosporine levels. One year after LDLLT, the patient is alive and well with no problems with daily life activities. © The Author 2014.

  7. 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.

  8. Eculizumab: safety and efficacy after 17 months of treatment in a renal transplant patient with recurrent atypical hemolytic-uremic syndrome: case report.

    Châtelet, V; Lobbedez, T; Frémeaux-Bacchi, V; Ficheux, M; Ryckelynck, J Ph; Hurault de Ligny, B


    In a recent study, eculizumab, a humanized monoclonal antibody which targets complement factor C5, appeared to resolve hemolysis and thrombocytopenia leading to recovery of renal function in a transplant patient during an episode of an atypical hemolytic uremic syndrome. We report the efficacy of eculizumab in a patient who presented with a recurrence of atypical hemolytic syndrome at 3 years after renal transplantation. After 17 months of eculizumab treatment, and without concomitant plasma therapy, renal function was maintained, the need for blood transfusions reduced, and acute thrombotic microangiopathy and hemolysis controlled. These data suggested that eculizumab should be considered to be a permanent treatment for this patient.

  9. Clinical efficacy and tolerability of caspofungin in a renal transplant patient with Aspergillus flavus lung infection: case report.

    Pasticci, M B; Barchiesi, F; Fallani, S; Palladino, N; Lapalorcia, L M; Gubbiotti, M; Cozzari, M; Novelli, A; Baldelli, F


    Organ transplant recipients are at increased risk for severe invasive aspergillosis, and amphotericin deoxycholate has been the standard treatment for many years. Currently, however, lipid formulations are preferred due to their few side effects. Also, a number of new antifungal drugs have been developed including new azoles and echinocandins. Caspofungin is the first of the echinocandin derivatives patented to treat patients with invasive aspergillosis who are refractory or intolerant to other therapies. A renal transplant patient on immunosuppressive treatment with chronic hepatitis B virus infection was admitted with fever, hemophthisis and lung consolidation, diagnosed to be probably caused by Aspergillus flavus. The patient developed cholestatic hepatitis most likely related to itraconazole. Clinical failure and in vitro itraconazole resistance of the isolate was also documented while the patient was receiving itraconazole at a reduced dosage. Caspofungin was administered once a day as ambulatory treatment and was well tolerated. Clinical improvement was observed after 6 weeks of treatment and no hepatic toxicity was documented. Caspofungin seems to be a potentially useful antifungal agent in renal transplant patients with invasive aspergillosis. Further evaluation of the efficacy of caspofungin is needed.

  10. Long-term outcome of renal transplantation in patients with familial Mediterranean fever amyloidosis: a single-center experience.

    Abedi, A S; Nakhjavani, J M; Etemadi, J


    Familial Mediterranean fever (FMF) is an autosomal-recessive disorder, affecting multiple organs. The AA type of amyloidosis is most common and serious complication cause nephropathy and end-stage renal disease (ESRD). Renal transplantation (RTX) remains treatment of choice for ESRD. We aimed to investigate long-term results of RTX in patients with FMF amyloidosis. We compared the outcomes of 18 patients (12 men and 6 women) with FMF amyloidosis among 601 (2.9%) transplants with 200 control patients. Demographic data and gene analysis were evaluated. In our study the 1-year graft and patient survivals were 94.44% and 100%, respectively. At 5 years after RTX, they were 94.73% and 88.88%, respectively, in the FMF group without difference from controls. Mean creatinine level at 1 and 5 years were 1.43 ± 0.54 and 1.73 ± 0.89, respectively. The results of MEFV mutation analyses were: M694V/M694V homozygote in 1 patient, M694V/EQ148 in 3, M694V/V726A in 2, 680M-I/E148Q in 3, M694V/M680I in 5, R202Q/M680I in 2, and M694V/R202Q in 2. Recurrence was noticed in 1 patient with M694V/M680I. One patient died because of graft loss and cardiac complications with M694V/M680I gene analysis. Colchicine was reduced in 4 patients owing to side effects. Long-term outcomes of transplantation in patients with amyloidosis secondary to FMF is similar to that in the general transplant population and maintenance colchicine, even after decreasing its dose, effectively prevents recurrence of amyloidosis in the allograft.

  11. 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

  12. Hyperkalemic distal renal tubular acidosis caused by immunosuppressant treatment with tacrolimus in a liver transplant patient: case report.

    Riveiro-Barciela, M; Campos-Varela, I; Tovar, J L; Vargas, V; Simón-Talero, M; Ventura-Cots, M; Crespo, M; Bilbao, I; Castells, L


    Nephrotoxicity is one of the most common side effects of long-term immunosuppressive therapy with calcineurin inhibitors. We describe a case of distal renal tubular acidosis secondary to tacrolimus administration. A 43-year-old man with end-stage liver disease due to hepatitis C and B virus infections and alcoholic cirrhosis received a liver transplantation under immunosuppressive treatment with tacrolimus and mycophenolate mofetil. In the postoperative period, the patient developed hyperkalemic hyperchloremic metabolic acidosis, with a normal serum anion gap and a positive urinary anion gap, suggesting distal renal tubular acidosis. We excluded other causes of hyperkalemia. Administration of intravenous bicarbonate, loop diuretics, and oral resin exchanger corrected the acidosis and potassium levels. Distal renal tubular acidosis is one of several types of nephrotoxicity induced by tacrolimus treatment, resulting from inhibition of potassium secretion in the collecting duct. Treatment to correct the acidosis and hyperkalemia should be promptly initiated, and the tacrolimus dose adjusted when possible.

End stage renal disease patients cannot excrete the appropriately potassium ion through the kidney. Among the crystalloid solutions, normal saline is devoid of potassium; so it is used in a widespread manner in renal transplant patients. High doses of this solution may cause hyperchloremic metabolic acidosis that is accompanied by extracellular potassium shift and impaired splanchnic perfusion. The aim of this study was to assess the effects of two types of solutions, normal saline vs. lactated ringer in these patients during the perioperative period. "n"nMethods: In a double blind clinical trial, 108 patients were randomly assigned in two groups (54 in each, while were assimilated regarding all aspects except for the type of the crystalloid solution.

    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.

    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.

    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.

    Rostaing, L; Oksman, F; Izopet, J; Baron, E; Cisterne, J M; Hoff, M; Abbal, M; Durand, D


    Chronic hepatitis C is the major cause of chronic liver disease after successful cadaveric renal transplantation. The aims of this prospective, open study were to assess in such a population, firstly the prevalence of different organ-specific and nonspecific antibodies and related disorders, and secondly their outcome after inteferon-alpha therapy as well as the incidence of new immunologic disorders under and after this therapy. In 15 cadaveric renal transplant patients (10 men, 5 women, ages 29-65 years) with chronic hepatitis C and histological features of chronic active hepatitis, undergoing chronic immunosuppression (ciclosporine A with or without steroid and azathioprine) and treated with recombinant alpha 2b-interferon (IFN alpha) (mean duration 142 +/- 35 days), we assessed before and after this therapy the serum levels of cryoglobulinemia, rheumatoid factors (RF), thyroid-stimulating hormone (TSH), free thyroxine (fT4), and antinuclear (ANA), antismooth muscle (ASMA), antimitochondrial (AMA), anti-LKM1, antimicrosomal thyroid (MCA), antithyroglobulin (TGA) autoantibodies. At the start of IFN alpha therapy, 14 of 15 patients had detectable autoantibodies (RF: 9; ANA > 1/50: 8; ASMA > 1/50: 4; other autoantibodies: 0); 1 had cryoglobulinemia. At the end of therapy the cryoglobulinemia had disappeared, the preexisting autoantibodies remained present in all patients but 2; 3 patients had developed MCA without evidence of clinical or biological thyroid abnormalities and 3 others had developed either RF (1) or ANA (1) or ASMA (1), without any related symptoms. One patient developed transient type II diabetes mellitus without anti-Langerhans beta-cell antibodies. Finally, the occurrence of autoantibodies in our patients was associated either with HLA DR3 or DR4 or DR7 phenotypes. We found that the prevalence of extrahepatic immunologic abnormalities was high in renal transplant patients with chronic hepatitis C and no exacerbation was observed during of after IFN

    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.

    Wang, Yi-xi; Li, Jia-li; Wang, Xue-ding; Zhang, Yu; Wang, Chang-xi; Huang, Min


    Co-administration of diltiazem can reduce the dosage of cyclosporine (CsA) in patients with renal transplantation. In this study, we investigated how diltiazem altered the relationship between MDR1 genetic polymorphisms and CsA concentration in Chinese patients with renal transplantation. A total of 126 renal transplant patients were enrolled. All the patients received CsA (2-4 mg·kg(-1)·d(-1)), and diltiazem (90 mg/d) was co-administered to 76 patients. MDR1-C1236T, G2677T/A, and C3435T polymorphisms were genotyped. The whole blood concentration was measured using the FPIA method, and the adjusted trough concentrations were compared among the groups with different genotypes. In all patients, MDR1-C1236T did not influence the adjusted CsA trough concentration. With regard to MDR1-3435, the adjusted CsA trough concentration was significantly higher in TT carriers than in CC and CT carriers when diltiazam was co-administered (58.83±13.95 versus 46.14±7.55 and 45.18±12.35 ng/mL per mg/kg, P=0.011), and the differences were not observed in patients without diltiazam co-administered. With regard to MDR1-2677, the adjusted CsA trough concentration was significantly higher in TT carriers than in GG and GT carriers when diltiazam was co-administered (61.31±12.93 versus 52.25±7.83 and 39.70±7.26 ng/mL per mg/kg, P=0.0001). The differences were also observed in patients without diltiazam co-administered (43.27±5.95 versus 35.22±7.55 and 29.54±5.35 ng/mL per mg/kg, P=0.001). The adjusted CsA trough blood concentration was significantly higher in haplotype T-T-T and haplotype T-T-C carriers than in non-carriers, regardless of diltiazem co-administered. MDR1 variants influence the adjusted CsA trough concentration in Chinese patients with renal transplant, and the influence more prominent when diltiazem is co-administered.

    Renal transplantation (RT), has been considered the best therapeutic option for end stage renal disease (ESRD). Objective. To determine the effect of RT on the evolution of oxidative DNA status. Methods. Prospective cohort (N = 50 receptors of RT); genotoxic damage, 8-hydroxy-2′-deoxyguanosine (8-OHdG), and DNA repair enzyme, human 8-oxoguanine-DNA-N- glycosylase-1 (hOGG1); and antioxidants, superoxide dismutase (SOD) and glutathione peroxidase (GPx), were evaluated. Results. Before RT, 8-OHdG were significantly elevated (11.04 ± 0.90 versus 4.73 ± 0.34 ng/mL) compared to healthy controls (p = 0.001), with normalization after 6 months of 4.78 ± 0.34 ng/mL (p < 0.001). The same phenomenon was observed with hOGG1 enzyme before RT with 2.14 ± 0.36 ng/mL (p = 0.01) and decreased significantly at the end of the study to 1.20 ng/mL (p < 0.001) but was higher than controls, 0.51 ± 0.07 ng/mL (p < 0.03). Antioxidant SOD was elevated at 24.09 ± 1.6 IU/mL versus healthy controls (p = 0.001) before RT; however, 6 months after RT it decreased significantly to 16.9 ± 1.6 IU/mL (p = 0.002), without achieving the levels of healthy controls (p = 0.01). The GPx, before RT, was significantly diminished with 24.09 ± 1.6 IU/mL versus healthy controls (39.0 ± 1.58) (p = 0.01), while, in the final results, levels increased significantly to 30.38 ± 3.16 IU/mL (p = 0.001). Discussion. Patients with ESRD have important oxidative damage before RT. The RT significantly reduces oxidative damage and partially regulates the antioxidant enzymes (SOD and GPx). PMID:27547292

  5. Introduction of MMF in conjunction with stepwise reduction of calcineurin inhibitor in stable liver transplant patients with renal dysfunction.

    Kornberg, Arno; Küpper, Bernadette; Hommann, Merten; Scheele, Johannes


    Mycophenolat mofetil (MMF) is a new imunosuppressant without nephrotoxic adverse effects. The aim of this study was to evaluate feasibility and effect of MMF introduction in conjunction with stepwise reduction of calcineurin inhibitors (CNI) in stable liver transplant patients with chronic CNI-induced renal dysfunction (RDF). In the MMF-group (n=27) but not in the controls (n=16), mean serum level of creatinine fell from a baseline of 227.4+/-67.9 micromol/l to 159.2+/-48.2 micromol/l (PMMF. Additionally, systolic and diastolic blood pressure values improved. In 52% of patients, dose reduction (n=11) or withdrawal (n=3) of MMF was necessary due to gastrointestinal or hematologic adverse effects. But also in patients on low dose MMF, there was a significant improvement of renal function without increased immunological risk.

  6. Enhancing patient engagement and blood pressure management for renal transplant recipients via home electronic monitoring and web-enabled collaborative care.

    Aberger, Edward W; Migliozzi, Daniel; Follick, Michael J; Malick, Tom; Ahern, David K


    Effective management of hypertension in chronic kidney disease and renal transplantation is a clinical priority and has societal implications in terms of preserving and optimizing the value of scarce organs. However, hypertension is optimally managed in only 37% of people with chronic kidney disease, and poor control can contribute to premature graft loss in renal transplant recipients. This article describes a telehealth system that incorporates home electronic blood pressure (BP) monitoring and uploading to a patient portal coupled with a Web-based dashboard that enables clinical pharmacist collaborative care in a renal transplant clinic. The telehealth system was developed and implemented as a quality improvement initiative in a renal transplant clinic in a large, 700-bed, urban hospital with the aim of improving BP in posttransplant patients. A convenience sample of 66 posttransplant patients was recruited by the clinical pharmacist from consecutive referrals to the Transplant Clinic. Preliminary results show statistically significant reductions in average systolic and diastolic BP of 6.0 mm Hg and 3.0 mm Hg, respectively, at 30 days after enrollment. Two case reports describe the instrumental role of home BP monitoring in the context of medication therapy management. Optimizing BP control for both pre- and post-renal transplant patients is likely to benefit society in terms of preserving scarce resources and reducing healthcare costs due to premature graft failure. Connected health systems hold great promise for supporting team-based care and improved health outcomes.

  7. Everolimus-associated stomatitis in a patient who had renal transplant.

    Ji, Yisi D; Aboalela, Ali; Villa, Alessandro


    Everolimus is used as an immunosuppressant in renal allograft transplant rejection and in metastatic breast cancer treatment. One side effect of everolimus is stomatitis, referred to as mammalian target of rapamycin inhibitor-associated stomatitis. This side effect can affect treatment course and contribute to discontinuation of therapy or dose reduction, previously reported in the treatment of metastatic breast cancer. Here, we present a case of everolimus-associated stomatitis with a novel management method with intralesional triamcinolone that allows for continuous course of everolimus.

  8. Long-term follow-up after conversion from tacrolimus to cyclosporin in renal transplant patients with new-onset diabetes mellitus after transplantation.

    Batista, F; Auyanet, I; Torregrosa, J-V; Oppenheimer, F


    The relationship between anticalcineurin (CNI) drugs and the development new-onset diabetes mellitus after kidney transplantation (NODAT) is well established. Among these agents cyclosporine shows lesser diabetogenicity than tacrolimus. It has been described that conversion from tacrolimus to cyclosporine improves glycemic control; however, there are no studies showing whether this reduced risk is maintained upon long-term follow-up. To evaluate whether CNI drugs conversion from tacrolimus to cyclosporine helps to maintain better glycemic control. We retrospectively evaluated the evolution of glucose metabolism at 5 years after conversion from tacrolimus to cyclosporine in eight patients (six men) with NODAT. Mean age was 42.8 ± 15 years, and time after transplantation to conversion 128 ± 40 months. We analyzed fasting serum glucose, lipid metabolism, renal function, and cyclosporine levels at 0, 6, 12, 24, 36, 48, and 60 months after conversion. At 6 months after conversion, improved glucose metabolism was observed (268 ± 161 versus 121 ± 31 mg/dL; P Cyclosporine levels remained stable during the follow-up. Conversion of renal transplant patients with NODAT from tacrolimus to cyclosporine improves glucose metabolism in the short term but glycemia increases thereafter. Copyright © 2012 Elsevier Inc.

  9. 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.

  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. Effect of perioperative blood transfusions on long term graft outcomes in renal transplant patients.

    O'Brien, Frank J


    It is established that blood transfusions will promote sensitization to human leucocyte antigen (HLA) antigens, increase time spent waiting for transplantation and may lead to higher rates of rejection. Less is known about how perioperative blood transfusion influence patient and graft outcome. This study aims to establish if there is an association between perioperative blood transfusion and graft or patient survival.

  12. Demography and survival of patients receiving treatment for chronic renal failure in Australia and New Zealand: report on dialysis and renal transplantation treatment from the Australia and New Zealand Dialysis and Transplant Registry.

    Disney, A P


    There were 7,059 (403 per million) Australian patients and 1,341 (388 per million) New Zealand patients receiving renal replacement treatment at the end of 1992. Fifty-three percent and 50%, respectively, were dependent on a functioning transplant, 87% and 80%, respectively, from a cadaver donor. In Australia the majority of dialysis patients depended on hemodialysis (68%) and continuous ambulatory peritoneal dialysis (CAPD) (31%); 68% of patients were dialysing at home or in a satellite (free-standing) facility. The majority (62%) of home dialysis patients used CAPD treatment. In New Zealand there were 44% of patients on hemodialysis; 83% dialyzed at home and the majority (65%) used CAPD treatment. Few dialysis units (five of 71) in Australia were "for-profit" facilities; there was none in New Zealand. Universal health care has been available for renal replacement treatment for 20 years. The annual incidence of new patients increased steadily during the past 10 years, to 61 per million (Australia) and 69 per million (New Zealand) in 1992. There were disproportionate numbers of indigenous Australian Aboriginals (51%), New Zealand Maoris (30%), and Polynesian Pacific Islanders (11%) compared with their distribution in the general population. There was a considerable increase in elderly and diabetic patients during the period from 1983 to 1992: in Australia, 25% of patients were over 65 years of age and 14% of patients were diabetic, and in New Zealand, 16% of patients were over 65 years of age and 25% of patients were diabetic. The renal transplantation rate has remained unchanged since 1983 at 27 per million in Australia, but has increased markedly from 20 to 33 per million in New Zealand. The annual transplantation rate was 20% to 30% of those patients aged 15 to 64 years who were likely to be transplanted. The multifactorial analysis of risk factors for survival of dialysis patients showed age, male gender, CAPD treatment, Aboriginal race, and diabetic or

  13. The prognostic value of heart rate response during vasodilator stress myocardial perfusion imaging in patients with end-stage renal disease undergoing renal transplantation.

    AlJaroudi, Wael; Anokwute, Chiedozie; Fughhi, Ibtihaj; Campagnoli, Tania; Wassouf, Marwan; Vij, Aviral; Kharouta, Michael; Appis, Andrew; Ali, Amjad; Doukky, Rami


    In asymptomatic end-stage renal disease (ESRD) patients undergoing vasodilator stress myocardial perfusion imaging (MPI) prior to renal transplantation (RT), the impact of pre-transplant heart rate response (HRR) to vasodilator stress on post-RT outcomes is unknown. We analyzed a retrospective cohort of asymptomatic patients with ESRD who underwent a vasodilator stress SPECT-MPI and subsequently received RT. Blunted HRR was defined as HRR <28% for regadenoson stress and <20% for adenosine stress. The primary endpoint was major adverse cardiac events (MACE), defined as cardiac death or myocardial infarction. Clinical risk was assessed using the sum of risk factors set forth by the AHA/ACCF consensus statement on the assessment of RT candidates. Among 352 subjects, 140 had an abnormal pre-transplant HRR. During a mean follow-up of 3.2 ± 2.0 years, 85 (24%) MACEs were observed. Blunted HRR was associated with increased MACE risk (hazard ratio 1.72; 95% confidence interval 1.12-2.63, P = 0.013), and remained significant after adjustment for gender, sum of AHA/ACCF risk factors, summed stress score, baseline heart rate, and β-blocker use. HRR was predictive of MACE in patients with normal MPI and irrespective of clinical risk. Blunted HRR was associated with a significant increase in post-operative (30-day) MACE risk (17.9% vs 8.5%; P = 0.009). In asymptomatic ESRD patients being evaluated for RT, a blunted pre-transplant HRR was predictive of post-RT MACE. HRR may be a valuable tool in the risk assessment of RT candidates.

  14. 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

    Chronic kidney disease (CKD) is an important public health problem. Kidney transplantation is associated with increase survival and improvement of quality of life. To describe the sociodemographic and clinical characteristics of patients registered in Castilla y León. To perform a survival analysis of transplant patients and their grafts. To evaluate survival depending on the transplant centre. Descriptive study with data collected until 31 December 2008 from the Registro de Diálisis y Trasplante Renal de la Comunidad de Castilla y León (REDI). The data was described differentiating prevalent and incidents patients. Survival data was assessed with the Kaplan-Meier method. On 31 December 2008, 2.498 patients were on Renal Replacement Therapy (RRT) (976.8 pmp); in 2008, 337 started treatment (131.8 pmp) and 94 received kidney transplant (36.8 pmp). The first cause of CKD for incident patients is diabetes (25.0%), followed by vascular diseases (18.1%). For prevalent patients: glomerulonephritis (16.5%) and diabetes (14.4%). Differences (p = 0.0021) were observed for the treatment initiation age, group of disease and prevalent patients (p <0.0001). During 11 years 1.062 transplants were performed in 1.012 patients and 879 are still functioning (83%). In this period, the survival probability for the transplant patients is 81.076% (± 0.023), and for the 838 patients with first functioning graft is 89.336% (± 0.016). Median graft survival is between 8.7 and 9.3 years (95% confidence). Most of the transplants during the last 11 years are still functioning. There are no differences when comparing graft survival at the approved centers in Castilla y León (p = 0.358).

  16. 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.

  17. 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.

  2. 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. Intestinal Parasitic Infections in Renal Transplant Recipients

    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.

    Tuberculosis is a serious opportunistic infection in renal transplant recipients and is disseminated in nature in one-third of patients. Genito urinary tuberculosis is rare in renal transplant recipients. We report a patient presenting 5 years after renal transplantation with disseminated tuberculosis and allograft and prostatic involvement.

  5. 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.

    Digital subtraction angiography (DSA) was performed in 53 of 417 patients with renal transplants. The incidence of clinical apparent vascular complications was 9.1% of all patients with renal transplants (38/417). The most frequent vascular disorders were formed by arterial stenoses at 5.0% of the cases followed by arterial obstructions in 1.7% of the patients. Rare vascular complications were arteriovenous fistulas (0.7%), aneurysms (0.5%) and venous thrombose (0.2%). Because of the high diagnostic value of intraarterial DSA, all patients with renal transplants with a complicated postoperative course should be eligible for angiographic control. In case of a suspected vascular disorder intraarterial DSA should be performed at an early stage. (orig.)

  7. IgA Cutaneous Purpura Post-Renal Transplantation in a Patient With Long-Standing IgA Nephropathy: Case Report and Literature Review.

    Sotoodian, Bahman; Robert, Janet; Mahmood, Muhammad N; Yacyshyn, Elaine


    IgA vasculitis is a small-vessel vasculitis caused by deposition of IgA antibodies in tissues. IgA nephropathy and IgAV have long been considered related conditions. To assess the prevalence and implications of new-onset Henoch-Schönlein purpura (HSP) after renal transplant in patients with underlying IgA nephropathy. The PubMed database was searched for keywords such as IgAV, IgA vasculitis, Henoch-Schönlein purpura, HSP, IgA nephropathy, and renal transplant. Two cases of new-onset IgA vasculitis post-renal transplant after stopping the prednisone or receiving seasonal influenza vaccine have been reported. We report the case of new-onset IgA cutaneous vasculitis in a renal transplant patient with IgA nephropathy after reduction in his prednisone dosage. The new development of cutaneous IgA vasculitis is unusual in renal transplant patients with IgA nephropathy. Despite these patients' being immunosuppressed, the presence of IgA vasculitis could signal the recurrence of IgA nephropathy. © The Author(s) 2015.

  8. Kidney transplantation in a patient with absent right common iliac artery and congenital renal abnormalities

    Clifton Ming Tay


    Conclusion: Kidney transplantation in such cases is safe and we recommend routine pre-operative imaging of patients known to have congenital genitourniary abnormalities. The kidney should be implanted heterotopically to the contralateral side of the vascular anomaly and care must be taken to preserve vascular supply to the lower limbs.

  9. 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.

The development of diabetes mellitus after renal transplant represents a major posttransplant complication that may adversely affect graft/patient survival. The aim of this study was to assess the role of metabolic syndrome in patients on hemodialysis as a risk factor for the incidence of new-onset diabetes mellitus after renal transplant.Patients and methods: This was a prospective observational epidemiologic study carried out in adult nondiabetic patients undergoing chronic hemodialysis and on the renal transplant waiting list between November 2008 and April 2009. Patients were followed up from Visit 1 (baseline to 6 months after the renal transplant. The analysis of the role of metabolic syndrome in hemodialysis patients as a risk factor for the incidence of new-onset diabetes mellitus after renal transplant included the estimation of relative risk and its 95% confidence interval (CI.Results: A total of 383 evaluable patients were entered into the study (mean age, 52.7 years; male, 57.7%; Caucasian, 90.1%. The prevalence of metabolic syndrome on hemodialysis was 30.4% (95% CI, 25.8%–35.4%. Hypertension was the most prevalent criterion for metabolic syndrome (65.0%, followed by low levels of high-density lipoprotein cholesterol (52.7%, abdominal obesity (36.2%, hypertriglyceridemia (32.4%, and impaired glucose (8.9%. After the renal transplant, the prevalence of metabolic syndrome was still 25.8%. During the posttransplant period, the incidence of new-onset diabetes mellitus reached 13.0% (95% CI, 7.8%–20.6% and patients with pretransplant metabolic syndrome were 2

Association studies lead to identification of patient risk profiles enabling individualization of level of immunosuppressions. We investigated the association of allograft rejection with interleukin-2 (IL-2, IL-4, IL-6, tumor necrosis factor-α (TNF-α –308, transforming growth factor-β (TGF-β (C-del, codon 10 and 25 gene variants in 184 renal transplant recipients and 180 controls. These cytokine genotypes were also evaluated with cyclosporine levels (C2 at one month in 135 stable recipients. High producing genotypes B1B1 of IL-4 and AA of TNF-α −308 showed significant association with rejection of allograft. The dose-adjusted C2 levels were significantly lower in patients with the high producing genotype T/T of IL-2 and heterozygous G/C of TGF-β codon 25 (P = 0.012 and 0.010, respectively. Haplotype frequencies were comparable in subjects for TGF-β codon-10 and 25. Combined inter-gene interaction showed high risk for rejection in recipients with high producing genotype B1B1 of IL-4 and AA of TNF-α and high TNF-α (AA with low TGF-β (CC or Pro/Pro. In conclusion, association of IL-4 VNTR and TNF-α –308 suggested the involvement of these cytokines contributing to pathogenesis of allograft rejection. Recipients with TT genotype of IL-2 and GC of TGF-β codon 25 having low C2 levels may require higher cyclosporine dosage. Combined analysis of gene-gene interaction demonstrated synergistic effect of cytokines increasing risk for rejection. Thus, this information may help in pre-assessment of allograft outcome

  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.

  14. De novo malignancy is associated with renal transplant tourism.

    Tsai, Meng-Kun; Yang, Ching-Yao; Lee, Chih-Yuan; Yeh, Chi-Chuan; Hu, Rey-Heng; Lee, Po-Huang


    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

  17. 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.

  18. Calcineurin-inhibitor minimization in liver transplant patients with calcineurin-inhibitor-related renal dysfunction: a meta-analysis.

    Yuan Kong

    Full Text Available BACKGROUND: Introduction of calcineurin-inhibitor (CNI has made transplantation a miracle in the past century. However, the side effects of long-term use of CNI turn out to be one of the major challenges in the current century. Among these, renal dysfunction attracts more and more attention. Herein, we undertook a meta-analysis to evaluate the efficacy and safety of calcineurin-inhibitor (CNI minimization protocols in liver transplant recipients with CNI-related renal dysfunction. METHODS: We included randomized trials with no year and language restriction. All data were analyzed using random effect model by Review Manager 5.0. The primary endpoints were glomerular filtration rate (GFR, serum creatinine level (sCr and creatinine clearance rate (CrCl, and the secondary endpoints were acute rejection episodes, incidence of infection and patient survival at the end of follow-up. RESULTS: GFR was significantly improved in CNI minimization group than in routine CNI regimen group (Z = 5.45, P<0.00001; I(2 = 0%. Likely, sCr level was significantly lower in the CNI minimization group (Z = 2.84, P = 0.005; I(2 = 39%. However, CrCl was not significantly higher in the CNI minimization group (Z = 1.59, P = 0.11; I(2 = 0%. Both acute rejection episodes and patient survival were comparable between two groups (rejection: Z = 0.01, P = 0.99; I(2 = 0%; survival: Z = 0.28, P = 0.78; I(2 = 0%, respectively. However, current CNI minimization protocols may be related to a higher incidence of infections (Z = 3.06, P = 0.002; I(2 = 0%. CONCLUSION: CNI minimization can preserve or even improve renal function in liver transplant patients with renal impairment, while sharing similar short term acute rejection rate and patient survival with routine CNI regimen.

  19. 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.

  20. 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.

  1. 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.

  2. 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.

  4. Panel-reactive antibody levels and renal transplantation rates in sensitized patients after desensitization and human leucocyte antigen amino acid residue matching.

    Shang, Wenjun; Dong, Laidong; Feng, Guiwen; Wang, Yue; Pang, Xinlu; Li, Jinfeng; Liu, Lei; Zhang, Weihong


    To determine whether a new desensitization protocol (mycophenolate mofetil [MMF], plasmapheresis and antithymocyte globulin [ATG], complemented with human leucocyte antigen [HLA] amino acid residue matching) could reduce panel-reactive antibody (PRA) levels in sensitized patients, to facilitate successful renal transplantation. Patients awaiting transplantation with PRA levels >10% received treatment with MMF; those with PRA levels >30% were also treated with plasmapheresis. Patients whose PRA level was desensitization were eligible for transplantation. When a donor became available, traditional HLA matching and HLA amino acid residue matching were performed. All patients received ATG induction therapy postoperatively. Thirty-two sensitized patients were enrolled. Desensitization produced a significant decrease in PRA levels; 27 patients (84.4%) became eligible for transplantation and 26 (81.2%) subsequently underwent successful transplantation. Residue matching improved the proportion with a mismatch number of 0-1 from 7.7% to 65.4%, compared with traditional HLA matching. Postoperatively, all patients showed immediate graft function. Acute rejection occurred in three patients (11.5%) and infections in seven patients (25.9%); all were treated successfully. The combination of a desensitization protocol (MMF, plasmapheresis and ATG) and residue matching appears to be an effective strategy for sensitized patients awaiting renal transplantation.

    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.

  6. [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.

    Restless legs syndrome is a disorder in which patients have irresistible urge to move legs during rest. Restless legs syndrome seems to be common in end-stage renal disease. After a successful renal transplant, symptoms ameliorate with renal function improvement and restless legs syndrome is seen less in this population. Here, we aimed to investigate restless legs syndrome frequency and associated factors in renal transplant patients. In a cross-sectional study with 193 patients (116 hemodialysis patients, 45 transplant patients, and 32 controls), the presence of restless legs syndrome was assessed using the Restless Legs Syndrome Questionnaire. Medical history, demographic, and laboratory data were collected from the patients' medical records. Patients were questioned about the presence of restless legs syndrome using the Restless Legs Syndrome Questionnaire. Patients were evaluated with Beck Depression Scale for depression and Pittsburgh tests for sleep disturbances. While the rate of restless legs syndrome was similar between transplants and controls, it was significantly greater in hemodialysis patients. Hemodialysis patients and controls had similar depression scores that were higher compared with transplant patients. Pittsburgh score was similar in transplant patients and controls and significantly increased in the hemodialysis patients. The rate of insomnia was significantly higher in the hemodialysis patients compared with the other 2 groups. Logistic regression analysis revealed independent correlates of restless legs syndrome as insomnia, Beck depression score, and being on hemodialysis. Linear regression analysis showed that independent correlates of higher Pittsburgh score were higher depression score, higher age, and presence of restless legs syndrome. The prevalence of restless legs syndrome is significantly lower in transplant patients than it is in patients on maintenance dialysis. In renal transplant patients, restless legs syndrome frequency was

  8. 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.

    Background/Aim. Polymorphisms of genes which encode transporter P-glycoprotein and most important enzymes for tacrolimus pharmacokinetics can have significant influence reflecting on blood concentrations of this drug. The aim of this study was to examine the distribution of polymorphisms of CYP3A5, CYP3A4 and ABCB1 genes in patients subjected to renal transplantation, for the first time in our transplantation center. Methods. The research was designed as a prospective cross-sectional study wh...

  10. [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.

  11. [Amyloidosis associated with chronic granulomatous disease in a patient with a renal transplant and recurrent urinary tract infections].

    Peces, R; Ablanedo, P; Seco, M


    Chronic granulomatous disease is a group of syndromes which share a defect in a component of the phagocyte NADPH-oxidase complex. Without this enzyme activity, phagocytic cells cannot produce superoxide, peroxide, and other potent microbicidal radicals, and are less able to kill ingested pathogens. The clinical picture is characterised by recurrent life-threatening bacterial and fungal infections and abnormal tissue granuloma formation. On the other hand, amyloidosis is a systemic disease with renal involvement occurring in the majority of cases. Recurrent amyloidosis is a rare but well documented event in renal transplant recipients. However, graft loss secondary to amyloidosis has been noted infrequently. In addition, de novo amyloidosis has not been previously associated with graft loss. We report here a renal transplant recipient with chronic granulomatous disease and history of recurrent urinary tract infections, who developed nephrotic syndrome and progressive renal insufficiency secondary to de novo AA amyloidosis leading to graft loss 66 months after transplantation.

    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.

  13. 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.

  14. 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

  15. 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.

  16. C2 (2-h) levels are not superior to trough levels as estimates of the area under the curve in tacrolimus-treated renal-transplant patients

    Jørgensen, Kaj; Povlsen, Johan; Madsen, Søren


    BACKGROUND: Recently, 2-h samples (C2) have been found superior to trough levels for therapeutic monitoring of transplanted patients receiving cyclosporin. The present study was undertaken to see if the same was the case for tacrolimus. METHODS: Blood tacrolimus levels were determined in 21...... consecutive patients at 3 and 14 days after renal transplantation, and before and 1, 2, 3, 4, and 6 h after oral intake of 0.1 mg/kg tacrolimus. The area under the blood concentration/time curve (AUC) was determined by the trapezoidal method, association between blood concentration at each sampling time...... with the highest AUC developed nephrotoxicity despite trough levels in the desired range. CONCLUSIONS: Two-hour levels are not superior to trough levels in tacrolimus-treated renal transplant patients. Despite good correlation between trough level and AUC, some patients may still receive nephrotoxic doses despite...

  17. 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.

  18. Hyperthyroidism in a renal transplant recipient.

    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.

  19. A randomized trial comparing renal function in older kidney transplant patients following delayed versus immediate tacrolimus administration.

    Andrés, Amado; Budde, Klemens; Clavien, Pierre-Alain; Becker, Thomas; Kessler, Michèle; Pisarski, Przemyslaw; Fornara, Paolo; Burmeister, Dirk; Hené, Ronald J; Cassuto-Viguier, Elisabeth


    This large, randomized, multicenter trial evaluated if basiliximab induction and delayed tacrolimus can preserve renal function in older kidney transplant patients. Patients aged 60 years and older received delayed tacrolimus with basiliximab and mycophenolate mofetil with early steroid discontinuation (Tac-d, n=132) or standard tacrolimus with mycophenolate mofetil and steroids until day 91 (Tac-s, n=122). Tacrolimus trough levels were 5 to 10 ng/mL after day 43 in both groups. Renal function at month 6 was measured by calculated creatinine clearance (Cockcroft-Gault formula). In both groups, mean recipient age was 66 years, mean donor age was 63 years with 73% of donors aged 60 years and older. Steroid discontinuation was slower than protocol specified. In the Tac-d group, 56.1% were steroid free at day 14 and 81.8% at month 6. In the Tac-s group, 37.7% were steroid free at month 4 and 63.9% at month 6. Mean (+/-SD) calculated creatinine clearance was 45.7+/-16.1 mL/min (Tac-d) and 45.0+/-18.2 mL/min (Tac-s) (P=ns), mean glomerular filtration rate (modified diet in renal disease formula) was 44.9+/-16.2 mL/min and 41.6+/-16.8 mL/min, respectively. Incidences of biopsy-proven acute rejection were 18.9% (Tac-d) and 18.0% (Tac-s). Delayed graft function was 30.3% (Tac-d) and 23.8% (Tac-s). Estimated patient survival rates (Kaplan-Meier) in the Tac-d and Tac-s groups were 96.1% vs. 99.2% and estimated graft survival rates were 90% vs. 87.6%, respectively. Safety results were similar with both regimens. Delayed tacrolimus with basiliximab induction did not provide an advantage in preserving renal function or reducing delayed graft function in older kidney transplant patients.

  20. Aspergillus thyroiditis in a renal transplant recipient mimicking subacute thyroiditis.

    Solak, Y; Atalay, H; Nar, A; Ozbek, O; Turkmen, K; Erekul, S; Turk, S


    Fungal pathogens are increasingly encountered after renal transplantation. Aspergillus causes significant morbidity and mortality in transplant patients. Fungal thyroiditis is a rare occurrence owing to unique features of the thyroid gland. Most cases are caused by Aspergillus species and have been described in immunocompromised patients. Presentation may be identical with that of subacute thyroiditis, in which hyperthyroidism features and painful thyroid are the prominent findings. Diagnosis can be ascertained by fine-needle aspiration of thyroid showing branching hyphae of Aspergillus. We describe a renal transplant patient who developed Aspergillus thyroiditis as part of a disseminated infection successfully treated with voriconazole.

  1. The Oral Cavity State in Renal Transplant Recipients

    Gašpar, Marija; Glavina, Ana; Grubišić, Kristina; Sabol, Ivan; Bušić, Mirela; Mravak, Marinka


    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. PMID:27688404

  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. Oral health in patients with renal disease: a longitudinal study from predialysis to kidney transplantation.

    Nylund, Karita M; Meurman, Jukka H; Heikkinen, Anna Maria; Furuholm, Jussi O; Ortiz, Fernanda; Ruokonen, Hellevi M


    The aim of this longitudinal study was to compare the oral health of chronic kidney disease patients at the predialysis (baseline) and post-transplantation (follow-up) stages and to investigate differences in oral health between diabetic nephropathy and other kidney disease patients at follow-up. Fifty-three kidney disease patients (34 men) aged 31-86 years were followed up to 157 months. Clinical and radiological oral examinations, salivary and laboratory analyses, and oral health behavior questionnaires were conducted at the predialysis and follow-up stages at Helsinki University Hospital, Finland. Oral inflammatory burden was estimated by calculating deep periodontal pockets, periodontal inflammatory burden (PIBI), decayed, missing, and filled teeth (DMFT), and total dental indices (TDI). Results were analyzed using cross-tabulation Pearson chi-square or Fisher's exact test and the Mann-Whitney U test, and the McNemar and Wilcoxon signed-rank test. At the predialysis stage, patients more often had calculus and deep periodontal pockets; TDI, PIBI, number of teeth, and salivary flow rates were also statistically significantly higher compared to follow-up. At follow-up, diabetic nephropathy patients more often had Candida growth, more plaque, and used more drugs and had lower stimulated salivary flow than patients with other kidney diseases. Oral health was better at follow-up than at the predialysis stage; however, attention should be given to the lower salivary flow rate and higher number of drugs used at that stage. This study confirms the importance of treating oral infectious foci at the predialysis stage in order to prevent adverse outcomes after kidney transplantation.

  4. 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.

  8. Outcome of Renal Transplant in Recipients With Vasculitis.

    Barbouch, Samia; Hajji, Meriam; Aoudia, Raja; Ounissi, Monther; Zammouri, Asma; Goucha, Rym; Ben Hamida, Fathi; Bacha, Mohammed Mongi; Abderrahim, Ezzedine; Ben Abdallah, Taieb


    End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center. We conducted a retrospective study of patients followed for chronic renal failure associated with vasculitis before renal transplant. We excluded patients with no biopsy-proven nephropathy. There was no difference in the occurrence of metabolic and cardiovascular complications in our case group compared with the other graft recipients. Infections were frequent and included cytomegalovirus and urinary tract infection. The rates of bacterial and viral infection were equivalent in our population. The incidence of allograft loss was estimated at 1.8%, less than that seen in our entire transplant population. The presence of vasculitis was not significantly related to renal failure (P = .07). Extrarenal relapse occurred in 1 patient with microscopic polyangiitis. Antineutrophil cytoplasmic antibody levels in patients with granulomatosis with polyangiitis and microscopic polyangiitis did not seem to influence the renal outcome (P = .08). Circulating antineutrophil cytoplasmic antibodies were associated with the development of vascular lesions in the graft but were not significantly correlated with graft survival (P = .07). This study supports the theory that renal transplant is an effective treatment option for patients with end-stage renal disease secondary to vasculitis. These patients fare similarly to, if not better than, other patients.

  9. Subcutaneous phaeohyphomycosis due to Alternaria infectoria in a renal transplant patient: surgical treatment with no long-term relapse.

    Salido-Vallejo, Rafael; Linares-Sicilia, María José; Garnacho-Saucedo, Gloria; Sánchez-Frías, Marina; Solís-Cuesta, Francisco; Gené, Josepa; Moreno-Giménez, José Carlos


    Phaeohyphomycosis can be caused by a number of different species, being the most common Alternaria alternata and Alternaria infectoria. The biggest risk factor for the development of the infection is immunosuppression. We present the case of a 64-year-old male renal transplant patient who came to hospital for presenting a tumour in the Achilles region which had been gradually growing in size. A skin biopsy was taken for histological study and culture of fungi and mycobacteria. Blood tests and imaging studies were performed. Histopathology study and cultures identified A. infectoria as the causal agent. Imaging studies ruled out internal foci of infection. The lesion was surgically removed with no signs of recurrence after 24 months of follow-up. There are no treatment guidelines at present for cutaneous and subcutaneous Alternaria spp. infections. Various systemic antifungals have been used, either in combination with surgical removal or alone, with varying results. Surgery alone could be useful in the treatment of solitary, localised lesions in transplant patients in whom there are difficulties in controlling immunosuppression.

  10. A survey on the effects of Azithromycin in the treatment of gingival overgrowth induced by Cyclosporin in renal transplant patients

    Kadkhoda Z.


    Full Text Available Statement of Problem: Gingival overgrowth is a side effect commonly induced by Cyclosporin treatment. The effects of Azithromycin, a macrolidic antibiotic, has been focused on gingival enlargement treatment induced by cyclosporine in numerous articles. Purpose: The goal of the present study was to survey the effects of systemic Azithromycin in the treatment of gingival overgrowth induced by cyclosporine among renal transplant patients. Materials and Methods: In this clinical trial study, 18 renal transplant patients (6 females and 12 males with gingival overgrowth were studied. Samples were randomly divided into two groups: case group were treated by systemic Azithromycin and controls were treated by systemic placebo. Periodontal parameters including bleeding on probing (BOP, clinical crown length (CL, periodontal pocket depth (PPD, gingival overgrowth (GOI and stent-IDP (vertical distant between a stent or plate with teeth occlusal planes at least from three of the most anterior contact points to mesial papillae before treatment, two and six weeks after treatment were measured. To analyze the data, Wilcoxon and Mann-Whitney tests were used. Results: Most of the measured indices, among case and control groups, were significantly improved, after two weeks (P<0.05. No statistically significant differences were found between two groups except for BOP index (P<0.05. In other words, more BOP improvement was observed in the case group after six weeks comparing to the control group. Conclusion: Considering the findings of this study, one can assume that the reported effects of Azithromycine on gingival overgrowth, induced by cyclosporine is somehow exaggerated and the effects attributed this medicine is probably inflammation reduction.

  11. 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'.

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

    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.

  13. Intractable urinary tract infection in a renal transplant recipient

    Satish Renuka


    Full Text Available Urinary tract infections (UTI are the most common bacterial infections after renal transplantation and are associated with significant morbidity and mortality. Recurrent or relapsing infections are not uncommon in the early post-transplant period and superadded fungal UTI can occur in these patients, posing a difficult therapeutic problem. Literature on recurrent UTI after transplant as well as the ideal approach to such patients is scanty. We present the case of a renal al-lograft recipient who presented with relapsing bacterial UTI complicated by systemic fungemia; also, a brief review of fungal UTI is attempted.

  14. 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.

  15. 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

  16. Correlation between the pharmacological efficacy of cyclosporine and tacrolimus as evaluated by the lymphocyte immunosuppressant sensitivity test (LIST) and the MTT assay procedure in patients before and after renal transplantation.

    Sugiyama, K; Isogai, K; Toyama, A; Satoh, H; Saito, K; Nakagawa, Y; Tasaki, M; Takahashi, K; Hirano, T


    Cyclosporine and tacrolimus are calcineurin inhibitors that are used to prevent acute rejection in renal transplant recipients. The lymphocyte immunosuppressant sensitivity test (LIST) can predict the pharmacological efficacy of these immunosuppressive agents for renal transplant recipients. There is a correlation between cyclosporine and tacrolimus pharmacological efficacy as evaluated by LIST by the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay procedure prior to renal transplantation. However, the LIST can also evaluate patients before and after the transplantation. The present study examined the relationship between cyclosporine and tacrolimus pharmacological efficacy by LIST using the MTT assay in 16 renal transplant recipients at 1, 3 and 12 months after transplantation, as well as before the operation. The relationship of cyclosporine and tacrolimus pharmacological efficacy gave a significant Kendall and Spearman's coefficient correlation in these transplant recipients by the LIST using the MTT assay procedure immediately prior to renal transplantation (rk = 0.711, rs = 0.877, p cyclosporine and tacrolimus IC50 values were also observed with a significant Kendall and Spearman's coefficient correlation at 1 and 12 months after transplantation (rk1month = 0.65, rs1month = 0.829, p transplantation (rk3month = 0.117, rs3month = 0.1, p > 0.05). Both cyclosporine and tacrolimus exhibit pharmacological efficacy by the inhibition of calcineurin. However, the correlation between cyclosporine and tacrolimus pharmacological efficacies may be altered, due to immunosuppressive therapy or clinical events at 3 months after renal transplantation.

  17. Oral manifestations of allograft recipients before and after renal transplantation

    Gita Rezvani


    Full Text Available Renal transplantation is considered the best treatment option for patients with end-stage renal disease. In this study, the prevalence of oral lesions was studied in a cohort of renal transplant recipients before and after transplantation. Fifty-nine kidney transplant recipients were examined one week before and four months after transplantation. The information gathered included age, sex, smoking history, duration on dialysis, drugs and their doses. There were 41 males (69.5% and 18 females (30.5% with a mean age of 37 years. Before surgery, two patients had non-specific lesions and two other patients had leukoedema. Following transplantation, 24 patients (40.7% did not have any specific lesion. In six patients, we observed non-specific erythematous lesions (10.2%. Other recorded observations are as follows: Gingival hyperplasia in five patients (8.5%, oral candidiasis of the erythematous type in five patients (8.5%, hairy leukoplakia in four patients (6.8% and leukoedema in seven patients (11.9%. In our study patients, the prevalence of oral lesions increased after transplantation, although it was lower than that reported in other studies. This could be due to the differences in sample size, differences between Iranian race and other races and different pharmaceutical formulation of the drug produced in Iran.

    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.

  19. 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.

  20. [Access to the waiting list and renal transplantation].

    Hourmant, M; de Cornelissen, F; Brunet, P; Pavaday, K; Assogba, F; Couchoud, C; Jacquelinet, C


    This chapter provides a set of indicators related to Renal Transplantation access in France. It describes patient outcomes and reports on cumulative incidence rates of wait-listing and renal transplantation according to main patient of characteristics and regions. The REIN registry integrates kidney transplant and dialysis data. It provides a comprehensive view on waiting list and renal transplantation access to the patients, nephrologists, and national or regional health authorities. Access to the waiting list is evaluated on a cohort of 51,845 new patients who started dialysis between 2002 and 2011 in 25 regions. The probability of first wait-listing was of 3.7% at the start of dialysis (pre-emptive registrations), 15% at 12, 22% at 36 and 24% to 60 months. The probability of being registered was strongly related to age, diabetes and region. Patient older than 60 had a very poor access to the waiting list, whatever their diabetes status was. Probability of first wait-listing was much lower (36.5% at 60 months) in type 2 diabetic-40 to 59 years old patients. Among 13,653 patients less than 60 years old, the probability of being registered was 11% at the start of dialysis, 43% to 12 months, 62% to 36 months and 66% to 60 months (median dialysis duration: 16 months). Seventeen regions with up to 5 years follow-up show an increase of 8 to 15% in pre-emptive registrations between 2007 and 2001, without change at 1 year. Access to kidney transplant is evaluated on a cohort of 53,301 new patients who started a renal replacement therapy (dialysis or pre-emptive renal transplant) between 2002 and 2011 in 25 regions. The probability of first kidney transplant was of 7% at 12, 17% at 36 and 21% at 60 months. 8,633 patients (16,2%) had received a first renal transplant within 14.7 month median time; 1,455 (2.7%) had received a pre-emptive graft [male: 58%, median age: 48.7y]. Among the 14,770 new patients less than 60 years old, the probability of being transplanted was of

  1. 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.

  2. Transplante renal em paciente pediátrico com associação de Vater: relato de caso Transplante renal en paciente pediátrico con asociación de Vater: relato de caso Renal transplantation in Vater association patient: case report

    Antonio Paulo Nogueira Costa


    : La asociación de Vater es una ocurrencia extremamente rara y compleja y el presente relato se prende a la realización, por la primera vez, de transplante renal con donador cadáver en niño portador de ese defecto congénito cuyo resultado fue enteramente satisfactorio.BACKGROUND AND OBJECTIVES: Vater association is a polytopic disorder including several malformations of which radial hypoplasia is the most common observed at birth. This report aimed at describing a case of Vater association in a child submitted to renal transplantation. CASE REPORT: Male patient, 11 years old, 23 kg, Hbs positive, submitted to esophagostomy at 30 hours of life. Since 7 years of age patient is submitted to hemodialysis, currently via atrial catheter for the lack of other access ways. Renal transplantation with cadaver donor was performed without intercurrences with adequate diuresis after vascular anastomoses. Right iliac fossa hematoma was drained in the first postoperative day. Patient was discharged 21 days after transplantation with normal renal function. CONCLUSIONS: Vater association is an extremely rare and complex event and this report aimed at describing for the first time a renal transplantation with cadaver donor in a child with this congenital defect, the result of which has been fully satisfactory.

  3. 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.

  4. Tophaceous gout of the lumbar spine in a renal transplant patient: a case report and literature review

    Thornton, Frank J. E-mail:; Torreggiani, William C.; Brennan, Paul


    Tophaceous gout of the spine is rare. We report the case of a 27-year-old male, renal transplant recipient, who presented with an acute onset of lower back pain. Radiological, biochemical and histo-pathological findings confirmed a diagnosis of tophaceous gout of the lumbar spine. We present the case history with the radiological findings and discuss the literature.

  5. Challenges in Special Populations: HIV/HCV Coinfection, Liver Transplantation and Patients with End-Stage Renal Disease.

    Bonacci, Martín; Lens, Sabela; Mariño, Zoe; Forns, Xavier

    Until recently, the combination of PEG-interferon and ribavirin (RBV) was the main treatment for all genotypes of chronic hepatitis C virus (HCV) infection. Sustained virological response (SVR) rates varied signixFB01;cantly across patient subgroups and the concept of 'special populations' emerged. Now, in the era of direct acting antivirals, with a better safety profile and higher efficacy rates, those patients with comorbidities or conditions that limited IFN-based antiviral treatment but with unmet medical needs have been considered for therapy again. With the currently approved all-oral antivirals, patients coinfected with human immunodeficiency virus and HCV have SVR rates similar to patients with HCV monoinfection. However, drug-drug interactions (DDIs) with antiretroviral drugs are still challenging. In the setting of liver transplantation, with an accelerated course of hepatitis C, previous IFN-RBV treatments were poorly tolerated and attained low SVR rates. Today, all-oral therapies have proven to be efficacious and safe in this population. Nevertheless, questions such as the optimal treatment duration or the need for RBV still remain opened. In this population as well, DDIs are an issue, as some regimens require adjustments and monitoring of immunosuppressive drugs during therapy. Finally, preliminary data show promising results in terms of efficacy and safety in patients with end-stage renal disease. However, there is clear need for more clinical studies since treatment options are still very limited.

  6. 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.

    Borrego, J; Burgos, F J; Galmes, I; Orofino, L; Rodríguez Luna, J M; Marcen, R; Fernández, E; Escudero, A; Ortuño, J


    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.

    Fatma Elif Demirgüneş


    Full Text Available Background and Design: This study is designed to determine the prevalence and the clinical spectrum of skin diseases in renal transplant recipients (RTRs.Material and Method: In this study RTRs who were referred to our department between 2005 and 2007 for dermatologic examination were evaluated. Dermatologic investigation included direct clinical observation and culture or histolopathological investigation when indicated. Patients were divided into three groups: group A, post-transplantation periods £1 year; group B, post-transplantation periods of 1-5 years; and group C, post-transplantation periods >5 years. Results: In this study 88 (M=50, F=38 RTRs were evaluated. The mean age was 37 ± 12 years and the median interval since transplantation was 38.5 months (range=1 month-27 years. Over a 2-year period 298 cutaneous manifestations were identified. Ninety-five immunosuppressive (IS drug-related manifestations were observed in 58 (%65.9 patients and the most common one was acneiform eruption (n=23. Forty (45.5% patients developed cutaneous viral infections, consisting of verruca vulgaris (n=29, herpes zoster (n=9, herpes simplex (n=5, molluscum (n=2 and varicella (n=1 infections. Superficial fungal infections were observed in 35(39.2% patients, most common lesions were dermatophytosis (n = 23 and pityriasis versicolor (n=17. Bacterial infections were observed in 14 (%16 patients, folliculitis was present in 12 of them. Premalignant and malignant lesions were identified in 12 (%13.6 patients, consisting of actinic keratoses (n=9, basal cell carcinoma (n=2, squamous cell carcinoma (n=1 and Kaposi's sarcoma (n=1. There were more premalignant and malignant lesions in patients receiving azathioprine (p=0.002. Cutaneous viral infections were more common in group C (p=0.023 and IS drug-related manifestations were more common in group A (p=0.003. Conclusion: Most common cutaneous manifestation among RTRs was IS drug-related and seen in early post-transplantation

  9. Evaluation of allograft perfusion by radionuclide first-pass study in renal failure following renal transplantation

    Baillet, G.; Ballarin, J.; Urdaneta, N.; Campos, H.; Vernejoul, P. de; Fermanian, J.; Kellershohn, C.; Kreis, H.


    To assess the diagnostic value of indices measured on a first-pass curve, we performed 72 radionuclide renal first-pass studies (RFP) in 21 patients during the early weeks following renal allograft transplantation. The diagnosis was based on standard clinical and biochemical data and on fine needle aspiration biopsy (FNAB) of the transplant. Aortic and renal first-pass curves were filtered using a true low-pass filter and five different indices of renal perfusion were computed, using formulae from the literature. Statistical analysis performed on the aortic and renal indices indicated excellent reproducibility of the isotopic study. Although renal indices presented a rather large scatter, they all discriminated well between normal and rejection. Three indices have a particularly good diagnostic value. In the discrimination between rejection and Acute Tubular Necrosis (ATN), only one index gave satisfying results. The indices, however, indicate that there are probably ATN with an alternation of renal perfusion and rejection episodes where perfusion is almost intact. We conclude that radionuclide first-pass study allows accurate and reproducible quantitation of renal allograft perfusion. The measured parameters are helpful to follow up the course of a post-transplantation renal failure episode and to gain more insight into renal ischemia following transplantation.

  10. Clinical outcomes of kidney transplants on patients with end-stage renal disease secondary to lupus nephritis, polycystic kidney disease and diabetic nephropathy

    Nieto-Ríos, John Fredy; Builes-Rodriguez, Sheila Alexandra; Restrepo-Correa, Ricardo Cesar; Aristizabal-Alzate, Arbey; Ocampo-Kohn, Catalina; Serna-Campuzano, Angélica; Cardona-Díaz, Natalia; Giraldo-Ramirez, Nelson Darío; Zuluaga-Valencia, Gustavo Adolfo


    Background: Patients with lupus nephritis could progress to end-stage renal disease (10-22%); hence, kidney transplants should be considered as the treatment of choice for these patients. Objective: To evaluate the clinical outcomes after kidney transplants in patients with chronic kidney diseases secondary to lupus nephritis, polycystic kidney disease and diabetes nephropathy at Pablo Tobon Uribe Hospital. Methods: A descriptive and retrospective study performed at one kidney transplant center between 2005 and 2013. Results: A total of 136 patients, 27 with lupus nephritis (19.9%), 31 with polycystic kidney disease (22.8%) and 78 with diabetes nephropathy (57.4%), were included in the study. The graft survivals after one, three and five years were 96.3%, 82.5% and 82.5% for lupus nephritis; 90%, 86% and 76.5% for polycystic kidney disease and 91.7%, 80.3% and 67.9% for diabetes nephropathy, respectively, with no significant differences (p= 0.488); the rate of lupus nephritis recurrence was 0.94%/person-year. The etiology of lupus vs diabetes vs polycystic disease was not a risk factor for a decreased time of graft survival (Hazard ratio: 1.43; 95% CI: 0.52-3.93). Conclusion: Kidney transplant patients with end stage renal disease secondary to lupus nephritis has similar graft and patient survival success rates to patients with other kidney diseases. The complication rate and risk of recurrence for lupus nephritis are low. Kidney transplants should be considered as the treatment of choice for patients with end stage renal disease secondary to lupus nephritis. PMID:27226665

  11. Renal function at two years in liver transplant patients receiving everolimus: results of a randomized, multicenter study.

    Saliba, F; De Simone, P; Nevens, F; De Carlis, L; Metselaar, H J; Beckebaum, S; Jonas, S; Sudan, D; Fischer, L; Duvoux, C; Chavin, K D; Koneru, B; Huang, M A; Chapman, W C; Foltys, D; Dong, G; Lopez, P M; Fung, J; Junge, G


    In a 24-month prospective, randomized, multicenter, open-label study, de novo liver transplant patients were randomized at 30 days to everolimus (EVR) + Reduced tacrolimus (TAC; n = 245), TAC Control (n = 243) or TAC Elimination (n = 231). Randomization to TAC Elimination was stopped prematurely due to a significantly higher rate of treated biopsy-proven acute rejection (tBPAR). The incidence of the primary efficacy endpoint, composite efficacy failure rate of tBPAR, graft loss or death postrandomization was similar with EVR + Reduced TAC (10.3%) or TAC Control (12.5%) at month 24 (difference -2.2%, 97.5% confidence interval [CI] -8.8%, 4.4%). BPAR was less frequent in the EVR + Reduced TAC group (6.1% vs. 13.3% in TAC Control, p = 0.010). Adjusted change in estimated glomerular filtration rate (eGFR) from randomization to month 24 was superior with EVR + Reduced TAC versus TAC Control: difference 6.7 mL/min/1.73 m(2) (97.5% CI 1.9, 11.4 mL/min/1.73 m(2), p = 0.002). Among patients who remained on treatment, mean (SD) eGFR at month 24 was 77.6 (26.5) mL/min/1.73 m(2) in the EVR + Reduced TAC group and 66.1 (19.3) mL/min/1.73 m(2) in the TAC Control group (p < 0.001). Study medication was discontinued due to adverse events in 28.6% of EVR + Reduced TAC and 18.2% of TAC Control patients. Early introduction of everolimus with reduced-exposure tacrolimus at 1 month after liver transplantation provided a significant and clinically relevant benefit for renal function at 2 years posttransplant.

  12. Late renal dysfunction in adult survivors of bone marrow transplantation

    Lawton, C.A.; Cohen, E.P.; Barber-Derus, S.W.; Murray, K.J.; Ash, R.C.; Casper, J.T.; Moulder, J.E. (Medical College of Wisconsin Affiliated Hospitals, Milwaukee (USA))


    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.

    Schmid, A; Jacobi, J; Kuefner, M A; Lell, M; Wuest, W; Mayer-Kadner, I; Benz, K; Schmid, M; Amann, K; Uder, M


    Percutaneous renal biopsy (PRB) of kidney transplants might be prevented by an elevated risk of bleeding or limited access to the allograft. In the following, we describe our initial experience with 71 transvenous renal transplant biopsies in 53 consecutive patients with unexplained reduced graft function who were considered unsuitable candidates for PRB (4.2% of all renal transplant biopsies at our institution). Biopsies were performed via the ipsilateral femoral vein with a renal biopsy set designed for transjugular renal biopsy (TJRB) of native kidneys. Positioning of the biopsy system within the transplant vein was achievable in 58 of 71 (81.7%) procedures. The specimen contained a median of 10 glomeruli (range 0-38). Tissue was considered as adequate for diagnosis in 56 of 57 (98.2%) biopsies. With respect to BANFF 50.9% of the specimen were adequate (>10 glomeruli), 47.4% marginally adequate (1-9 glomeruli) and 1.8% inadequate (no glomeruli). After implementation of real-time assessment all specimen contained glomeruli. One of the fifty-eight (1.8%) procedure-related major complications occurred (hydronephrosis requiring nephrostomy due to gross hematuria). Transfemoral renal transplant biopsy (TFRTB) is feasible and appears to be safe compared to PRB. It offers a useful new alternative for histological evaluation of graft dysfunction in selected patients with contraindications to PRB.

  14. Relationship Between ADPKD and Post-Renal Transplant Diabetes Mellitus

    S. Seifi


    Full Text Available Background: Autosomal-dominant polycystic kidney disease (ADPKD, a common hereditary disease, is characterized by the progressive development and enlargement of multiple cysts in both kidneys, and typically resulting in end stage renal disease (ESRD by the fifth decade of life. Post-transplant diabetes mellitus (PTDM, a common complication after transplantation with an incidence rate of 2.5-20%, is associated with poor graft and patient survival. In few studies, PTDM has been more frequent in ADPKD transplanted patients. In the present study, we investigated whether there is any association between PTDM and ADPKD in our patients. Methods: In this prospective study, 140 non-diabetic and nonsmoker successfully transplanted patients (27 ADPKD and 113 non ADPKD patients were enrolled during three years. Both groups were matched for age, sex, body mass index (BMI, duration of renal replacement therapy before transplantation and also immunosuppressive protocols after transplant. Post-transplant diabetes mellitus was defined as Clinical Practice Guidelines advocated by Canadian Diabetes Association. All patients were followed for 12 months. Results: PTDM occurred in 11.1% of ADPKD patients and in 13.1% of control group which was statistically insignificant (P > 0.05. The development of PTDM in ADPKD group was not related to sex, age, and hypertension, duration of renal replacement therapy before transplantation, BMI and serum creatinine levels (P > 0.05. Conclusion: Post-transplant diabetes mellitus appears not to be associated with autosomal-dominant polycystic kidney disease as an etiology of end stage renal disease.

  16. Bilateral Septic Arthritis Complicating Knee Osteonecrosis in Renal Transplant Recipient: Case Report

    Erhan TATAR


    Full Text Available Septic arthritis is rarely seen in transplant patients and differs from the general population with regards to gram negative and/or atypical agents being the prominent causes. In renal transplant patients, osteonecrosis is one of the major musculo-skeletal complications. In transplant patients, immunosupressive drugs, delayed graft function, genetics, HD duration before transplantation, cause of renal failure are among the risk factors for ostenecrosis. In this case report, we present a renal transplant patient with bilateral knee osteonecrosis and septic arthritis due to Escherichia coli.

  17. [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.

  18. Disseminated Mycobacterium haemophilum infection in a renal transplant recipient.

    Brix, Silke R; Iking-Konert, Christof; Stahl, Rolf A K; Wenzel, Ulrich


    Opportunistic infections are a major concern in renal and transplant medicine. We present the case of a renal transplant recipient with a generalised Mycobacterium haemophilum infection after an increase in immunosuppressive therapy and treatment with a tumour necrosis factor-α (TNF-α) inhibitor. Infection involved skin and soft tissue, joints and bones, as well as the renal transplant with an interstitial nephritis. Rapid diagnosis using PCR and DNA sequencing allowed early appropriate treatment. Triple antibiotic therapy and reduction in immunosuppression resulted in a slow but sustained recovery. Immunosuppression causes severe opportunistic infections. TNF-α inhibitors are very effective and well tolerated but have an increased susceptibility to infections with mycobacteria. Mycobacterial infections represent a significant clinical risk to transplant recipients because of their aggressive clinical course and the need for complex toxic antibiotic treatments. In these patients, M. haemophilum is a cause of skin infections.

  20. 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

  2. The effect of prostaglandin E_1 on recovery of early renal graft functions after transplantation


    Objective To investigate the effect of prostaglandin E1 (PGE1) on recovery of early renal graft functions after transplantation. Methods One hundred and seven patients after renal transplantation were allocated in the treated group, and treated by conventional treatment with injection of 10 μg prostaglandin E1 additionally twice a day for 14 days. And eighty-eight patients who received conventional treatment alone after renal transplantation at the corresponding period were allocated in the control group. I...

  3. Everolimus-treated renal transplant recipients have a more robust CMV-specific CD8+ T-cell response compared with cyclosporine- or mycophenolate-treated patients.

    Havenith, Simone H C; Yong, Si La; van Donselaar-van der Pant, Karlijn A M I; van Lier, René A W; ten Berge, Ineke J M; Bemelman, Fréderike J


    In renal transplant recipients, mammalian target of rapamycin (mTOR) inhibitors have been reported to protect against cytomegalovirus (CMV) disease. Here, we questioned whether mTOR inhibitors specifically influence human CMV-induced T-cell responses. We studied renal transplant recipients treated with prednisolone, cyclosporine A (CsA), and mycophenolate sodium (MPS) for the first 6 months after transplantation followed by double therapy consisting of prednisolone/everolimus, which is an mTOR inhibitor (P/EVL; n=10), prednisolone/CsA (P/CsA; n=7), or prednisolone/MPS (P/MPS; n=9). All patients were CMV-IgG positive before transplantation. CMV reactivation was detectable in the first 6 months after transplantation and not thereafter. None of the patients included in this study suffered from CMV disease. Both CD27CD8 and CD27CD28CD4 effector-type T-cell counts, known to be associated with CMV infection, were measured before transplantation and at 6 and 24 months after transplantation. Additionally, we determined both number and function of CMV-specific CD8 T cells at these time points. The number of total CD8 T cells, CD27CD8 T cells, and CD28CD4 T cells increased significantly after switch to therapy with P/EVL but not after switch to P/CsA or P/MPS. Specifically, CMV-specific CD8 T-cell counts significantly increased after switch to therapy with P/EVL. Furthermore, the mTOR inhibitor sirolimus strongly inhibited alloresponses in vitro, whereas it did not affect CMV-specific responses. We observed a significant increase in (CMV-specific) effector-type CD8 and CD4 T-cell counts in everolimus-treated patients. These findings may at least in part explain the reported low incidence of CMV-related pathology in everolimus-treated patients.

  4. Forgotten ureteric stents in renal transplant recipients: three case reports.

    Bardapure, Mallikarjun; Sharma, Ajay; Hammad, Abdul


    Ureteric stents are widely used in renal transplantation to minimize the early urological complications. Ureteric stents are removed between two and 12 weeks following trans-plantation, once the vesico-ureteric anastomosis is healed. Ureteric stents are associated with considerable morbidity due to complications such as infection, hematuria, encrustations and migration. Despite the patient having a regular follow-up in the renal transplant clinic, ureteric stents may be overlooked and forgotten. The retained or forgotten ureteric stents may adversely affect renal allograft function and could be potentially life-threatening in immunocompromised transplant recipients with a single transplant kidney. Retrieving these retained ureteric stents could be challenging and may necessitate multimodal urological treatments. We report three cases of forgotten stents in renal transplant recipients for more than four years. These cases emphasize the importance of patient education about the indwelling ureteric stent and possibly providing with a stent card to the patient. Maintaining a stent register, with a possible computer tracking system, is highly recommended to prevent such complications.

  6. Reproductive health in Irish female renal transplant recipients.

    Kennedy, C


    OBJECTIVE: To report the pregnancy outcomes in Irish female renal transplant recipients on modern maintenance immunosuppression. METHODS: The Republic of Ireland transplant database was accessed to identify the patient cohort in question. All female renal transplant recipients whose transplantation was in Ireland before or during their reproductive years were included. A questionnaire was sent to the identified women. A chart review was performed for those women who reported a pregnancy following renal transplantation. RESULTS: Two hundred and ten women met the inclusion criteria. There was a response rate of 70% (n = 148). Eighteen women reported 29 pregnancies. The live birth rate was 76%. The mean gestation of the live births was 36.2 weeks with a mean birth weight of 3.0 kg. There were six cases of pre-eclampsia. Twin pregnancies and those entering pregnancy with a creatinine greater than 135 micromol\\/l had particularly complicated clinical courses. Four women had not conceived post transplant despite actively trying for over 1 year. Two women utilised assisted fertility methods (in vitro fertilisation), one of whom became pregnant. CONCLUSIONS: A significant proportion of women who attempt to conceive following renal transplantation are successful, without the use of assisted fertility. Pregnancy in this setting warrants meticulous multidisciplinary care.

  7. Post-transplant Lymphoproliferative Disorder Arising from Renal Allograft Parenchyma: A Case Report

    Post-transplant lymphoproliferative disorder (PTLD) is a rare but serious complication that occurs in patients undergoing kidney transplantation. PTLD usually manifests as a renal hilar mass comprised of histologically B-lymphocytes. We report our experience of managing a patient with PTLD arising from renal parenchyma. Ultrasonographic and MR imaging features of this unusual PTLD suggested differentiated renal cell carcinoma arising from the renal allograft

  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.

  9. Interleukin-10 gene promoter polymorphisms are associated with cyclosporin A-induced gingival overgrowth in renal transplant patients.

    Luo, Yixi; Gong, Yiming; Yu, Youcheng


    Interleukin-10 (IL-10) is an anti-inflammatory cytokine whose genetic polymorphisms are associated with the production of IL-10 and the susceptibility to periodontal diseases. The aim of this study was to investigate the possible association of IL-10 single nucleotide polymorphisms (SNPs) and cyclosporin A (CsA)-induced gingival overgrowth (GO) in renal transplant patients in a Chinese population, taking into account subgingival microbiota as additional variables. A total of 202 patients were dichotomized into two groups: 122 with GO and 80 without GO. The IL-10-1082 SNP, -819 SNP and -592 SNP were measured using an allele-specific PCR method. The levels of subgingival bacteria were measured by real-time PCR. Genotype and allele frequencies were analyzed using the Chi-square test and logistic regression analysis. The frequency of IL-10-819TT (-592AA) genotype was statistically higher in patients with GO than that in patients without GO (P<0.05). Multiple logistic regression analysis demonstrated that the prevalence of GO is not dependent on age, gender, and pharmacological variables, being significantly associated with the carriers of ATA haplotype (OR=2.425, 95%CI=1.214-4.845, P=0.012). Moreover, ATA positive carriers in the GO group presented significantly higher levels of Porphyromonas gingivalis and Treponema denticola than those negative carriers. Our results show that IL-10-819TT (-592AA) genotype and ATA halpotype are associated with susceptibility to CsA-induced GO. Meanwhile, ATA haplotype is associated with a higher detection of P. gingivalis and T. denticola in GO patients, and may increase the risk of developing GO. Copyright © 2013 Elsevier Ltd.

  10. Epidemiology of post-transplant malignancy in Chinese renal transplant recipients: a single-center experience and literature review.

    Zhang, Jian; Ma, Linlin; Xie, Zelin; Guo, Yuwen; Sun, Wen; Zhang, Lei; Lin, Jun; Xiao, Jing; Zhu, Yichen; Tian, Ye


    This study investigated the incidence and types of post-transplant malignancy in Chinese renal transplant recipients and the risk factors associated with malignancy. Data from 3,462 patients who underwent renal transplantation at Beijing Friendship Hospital were combined with data from 26 previous reports describing malignancy rates in 27,170 Chinese renal transplant recipients. Between 1974 and 2014, 179/3,462 (5.17 %) patients who underwent renal transplantation at our center developed malignancy. The most common site of malignancy was the urinary system, and the most common type was urothelial transitional cell carcinoma. Combined data from our center and previous reports showed malignancy in 671 (2.19 %) Chinese renal transplant recipients. The ten most common malignancies were urothelial transitional cell carcinoma (n = 283), hepatocellular carcinoma (n = 68), gastrointestinal cancer (n = 63), renal cell carcinoma (n = 42), lymphoma (n = 42), lung cancer (n = 28), breast cancer (n = 19), skin cancer (n = 18), Kaposi's sarcoma (n = 12), and cervical cancer (n = 10). The incidence of post-transplant malignancy in renal transplant recipients was lower in China than the reported rates in other countries, and the most common sites of malignancy were the urinary and digestive system. The relative frequency of malignancy sites differed between northern and southern China. Renal transplant recipients on long-term immunosuppressive therapy should receive careful follow-up, including annual or biannual screening for malignancy in high-risk individuals.

  11. 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

    Agüero, Fernando; Cofan, Frederic; Fortuny, Claudia; Lopez, Marta; Manzardo, Christian; Lonca, Montserrat; Oppenheimer, Frederic; Moreno, Asuncion; Campistol, Josep M; Miro, Jose M


    We report the first case of a pregnancy in a renal transplant recipient with HIV infection. She underwent renal transplantation in 2005 and became pregnant in 2009. The patient underwent vaginal delivery and a healthy full-term, female baby was born. Almost 6 years after delivery, both mother and child were doing well. The management of concurrent renal transplantation, HIV infection and pregnancy was extremely challenging. Women with HIV infection who have undergone renal transplantation should be accurately informed of the potential health risks for them and their offspring. Multidisciplinary teams are mandatory in order to properly manage these patients.

  15. Neisseria lactamica Causing a Lung Cavity and Skin Rash in a Renal Transplant Patient: First Report from India

    Khalid Hamid Changal


    Full Text Available Neisseria lactamica, a commensal, has been very rarely reported to cause diseases in immunocompromised hosts. In medical literature, there is only one report of a cavitatory lung lesion caused by it. The patient was a kidney transplant recipient. Neisseria lactamica was found to be the cause of his pulmonary cavity and a desquamating rash on feet. With the rapidly spreading medical advance, more and more patients are getting organ transplants, so the population of immunocompromised people is on the rise. We expect more sinister and less expected organisms to cause diseases in patients who have organ transplants.

  16. Visceral leishmaniasis in renal transplant recipients: successful treatment with liposomal amphotericin B (AmBisome).

    Boletis, J N; Pefanis, A; Stathakis, C; Helioti, H; Kostakis, A; Giamarellou, H


    Visceral leishmaniasis (VL) is a rare disease in renal transplant recipients. Liposomal amphotericin B (AmBisome) is known to be effective against VL. However, previously there has been no experience with administration of such treatment to renal transplant recipients. We report herein four patients with VL complicating renal transplantation who were treated successfully with liposomal amphotericin B (total dose, 23-40 mg/kg). Neither adverse reactions nor clinical relapses of VL were observed.

  17. Health information management for research and quality assurance: the Comprehensive Renal Transplant Research Information System.

    The Kidney Transplant Program at the Toronto General Hospital uses numerous electronic health record platforms housing patient health information that is often not coded in a systematic manner to facilitate quality assurance and research. To address this, the comprehensive renal transplant research information system was conceived by a multidisciplinary healthcare team. Data analysis from comprehensive renal transplant research information system presented at programmatic retreats, scientific meetings, and peer-reviewed manuscripts contributes to quality improvement and knowledge in kidney transplantation.

    An epidemiologic multicenter study was performed to evaluate the prevalence and management of gastrointestinal (GI) complications in solid organ transplant patients. A total of 1788 recipients were included, 1132 of which corresponded to renal transplanted patients. The mean age for the renal transplanted patients was 52 +/- 13.2 years. The mean time from the transplantation was 5.4 +/- 5.4 years. 17.7% showed some pretransplant GI disease, while 53% presented this type of complication in the posttransplant period. Diarrhea was the most prevalent GI complication (51.5%) and digestive perforation was the GI disorder that affected the patients daily living the most. From the patients with GI complications, 71% received pharmacological treatment, using gastric protectors in 91.3% of the cases. Regarding immunosuppressive drugs, in 30.9% of the cases the dose of the drug was reduced, in 9.3% discontinued temporarily and in 7.5% discontinued permanently. These changes mainly affected the MMF (89%, 83% and 74% for dose change, temporary and permanent discontinuation, respectively). The prevalence of GI complications in renal transplant exceeded 50%, and affected patients' daily living. The management of these complications was based on treatment with gastric protectors, dose reduction and/or partial or definitive MMF discontinuation.

  19. Re: Robot-Assisted Renal Transplantation in the Retroperitoneum

    Tsai MK


    Full Text Available The authors describe their first 10 cases of minimally invasive renal transplantation experience in the retroperitoneum with the aid of the da Vinci surgical system through a gas-less extra-peritoneal approach with a muscle sparing Gibson incision. The authors claim that they have utilized robotic arms for both vascular anastomosis and abdominal wall lifting which can be limiting in the obese patients. In recent years there is an increasing tendency for minimally invasive renal transplantation such as transperitoneal laparoscopic or robotic assisted renal transplantation. Those techniques still need modifications and search for a better technique is still in progress. In this study, mimicking the well-established open procedure with a smaller incision can be a better alternative, which requires confirmation in the future

  20. Recovery of renal function after prolonged dialysis and transplantation.

    Nunan, T O; Stevens, E A; Croft, D N; Hilton, P J; Jones, N F; Wing, A J


    Out of 250 patients with renal failure, seven (2.8%) treated by regular haemodialysis alone (four) or given cadaveric allografts (three) later showed recovery of function of their own kidneys lasting from one to four years. In the patients receiving haemodialysis alone recovery was easily recognised from their serum creatinine concentrations, but in those with transplants recovery was discovered unexpectedly during radionuclide scanning. These findings suggest that recovery of renal function may be more common than generally recognised, which should be borne in mind when beginning renal replacement treatment and particularly when contemplating bilateral nephrectomy.

    Silke Roedder


    Full Text Available Development of noninvasive molecular assays to improve disease diagnosis and patient monitoring is a critical need. In renal transplantation, acute rejection (AR increases the risk for chronic graft injury and failure. Noninvasive diagnostic assays to improve current late and nonspecific diagnosis of rejection are needed. We sought to develop a test using a simple blood gene expression assay to detect patients at high risk for AR.We developed a novel correlation-based algorithm by step-wise analysis of gene expression data in 558 blood samples from 436 renal transplant patients collected across eight transplant centers in the US, Mexico, and Spain between 5 February 2005 and 15 December 2012 in the Assessment of Acute Rejection in Renal Transplantation (AART study. Gene expression was assessed by quantitative real-time PCR (QPCR in one center. A 17-gene set--the Kidney Solid Organ Response Test (kSORT--was selected in 143 samples for AR classification using discriminant analysis (area under the receiver operating characteristic curve [AUC] = 0.94; 95% CI 0.91-0.98, validated in 124 independent samples (AUC = 0.95; 95% CI 0.88-1.0 and evaluated for AR prediction in 191 serial samples, where it predicted AR up to 3 mo prior to detection by the current gold standard (biopsy. A novel reference-based algorithm (using 13 12-gene models was developed in 100 independent samples to provide a numerical AR risk score, to classify patients as high risk versus low risk for AR. kSORT was able to detect AR in blood independent of age, time post-transplantation, and sample source without additional data normalization; AUC = 0.93 (95% CI 0.86-0.99. Further validation of kSORT is planned in prospective clinical observational and interventional trials.The kSORT blood QPCR assay is a noninvasive tool to detect high risk of AR of renal transplants.

  3. A rare complication after renal transplantation: Forgotten stent

    Mustafa Karabıcak


    Full Text Available In renal transplantation surgery, double J stents (DJS are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmantation, encrustation and rarely sepsis are among the late complications of DJS. In this report we describe a renal transplantation case whose DJS stent was forgotten because the patient did not attend the regular follow-up and noticed 5 years after surgery.

    Fernández Castillo, Rafael; Fernández Gallegos, Ruth; Peña Amaro, María Pilar; Esteban de la Rosa, Rafael José


    Introducción: las alteraciones del metabolismo lipídico y del metabolismo mineral óseo son trastornos frecuentes entre los pacientes trasplantados renales, lo que contribuye a la aparación de enfermedades matabólicas y cardiovasculares que ponen en peligro la integridad del injerto. Objetivo: describir y observar la evolución de las alteraciones de la densidad mineral ósea (DMO) y las alteraciones lipídicas en una población de pacientes trasplantados renales. Material y método: en este trabajo se ha seguido a 119 pacientes de ambos sexos trasplantados renales, a los cuales se les realizaron mediciones pretrasplante y postrasplante durante cinco años de parámetros bioquímicos, mediciones antropométricas y de la densidad mineral ósea en columna lumbar, fémur y radio-cubital. Resultados: durante los cinco años tras el trasplante se produce un importante aumento de parámetros bioquímicos, IMC, dislipemia, diabetes e hipertensión arterial. A los seis meses existe un alto porcentaje de pacientes con DMO patológica, aumentando un 4,1% al año del trasplante. Conclusiones: tras el trasplante se produce un gran incremento de la hiperlipidemia que se asocia con un patrón característico de alteración de lípidos con elevación del colesterol total, lipoproteínas de baja densidad, lipoproteínas de alta densidad, así como el consiguiente aumento de los triglicéridos, a pesar del tratamiento con estatinas, lo que conlleva un aumento en los factores de riego de padecer diabetes, hipertension arterial y enfermedades cardiovasculares; además se produce una pérdida de masa ósea, lo que conlleva un alto riesgo de sufrir fracturas graves, poniendo en peligro el injerto renal y la calidad de vida del paciente.

  5. Cervical Carcinoma in a Renal Transplant Recipient: A Case Report.

    Tuncer, Hasan Aykut; Kirnap, Mahir; Dursun, Polat; Ayhan, Ali; Moray, Gokhan; Haberal, Mehmet


    A range of cancer types, at increased rates, is described in renal transplant recipients receiving immunosuppression. Aside from immunodeficiency, heightened medical surveillance for cancer, lifestyle, and other risk factors all play a role. Although the relation between cancer risk and degree of immunodeficiency might not be linear, and might be different for a wide range of cancer subtypes, human papillomavirus-related cancers in long-term transplant recipients may suggest the role of even modest immunosuppression, when present long enough. High-risk human papillomavirus types are recognized as the cause of cancer of the cervix. We report a 49-year-old female renal transplant recipient diagnosed with cervical squamous cell carcinoma, 5 years after the transplant. Based on this patient, we highlight difficulties in surgical approach and the importance of close clinical follow-up including regular gynecologic screening for cervical premalignant and malignant lesions.

  6. Successful pregnancy in renal transplant recipient with previous known polyomavirus nephropathy.

    Midtvedt, Karsten; Bjorang, Ola; Letting, Anne-Sofie


    Pregnancy after renal transplantation has become increasingly common. Studies in non-immunocompromised patients have shown that pregnant women have increased susceptibility to infection or reactivation of latent virus such as BK virus. To what extent a renal transplant recipient is at risk for reactivation of polyoma virus during pregnancy remains unknown. We hereby report successful pregnancy outcome in a renal transplant recipient with a known history of BK virus nephropathy treated with cidofovir i.v. To our knowledge, this is the first published experience with a successful pregnancy in renal transplant recipients with known history of polyomavirus-associated nephropathy.

  7. 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.

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



    Full Text Available Background Several studies have been conducted on the relationship between a number of human leukocyte antigen (HLA alleles and cytomegalovirus infection (CMV, in kidney transplant recipients, after transplantation. However, only a limited number of HLAs have been investigated, so far, and the results have been contradictory. Objectives This study aimed to investigate the relationship between 59 HLA alleles and the CMV infection, in transplant recipients, after kidney transplantation. Patients and Methods This retrospective cohort study was conducted on 200 patients, receiving a kidney transplant, in Baqiyatallah Hospital, in Tehran, during 2013. Throughout a one-year follow-up of kidney transplant recipients, in case of detecting the CMV antigen in patients’ blood, at any time, they were placed in the group of patients with CMV infection, whereas, if no CMV-specific antigen was developed, over a year, patients were placed in the group of patients without CMV infection, after transplantation. This study investigated the relationship between CMV infection in kidney transplant recipients and 59 HLA alleles, including 14 HLA-A, 28 HLA-B, and 17 HLA-DRB1 cases. Results Of all participants, 104 patients (52% were diagnosed with CMV infection. There was no significant difference between the two groups, with and without CMV infection, in terms of patient’s characteristics. The CMV infection, in patients receiving a transplanted organ from deceased donor, was significantly more prevalent than in those receiving kidney transplant from living donor (63% vs. 39%, respectively, P = 0.001. Recipients with HLA-B44 were more infected with CMV compared with patients without this allele (80% vs. 50%, respectively, P = 0.024; on the contrary, kidney recipients with HLA-DRB1-1 were less infected with CMV than patients without this allele (31% vs. 55%, respectively, P = 0.020. There was no significant relationship between CMV infection and other HLA alleles

  9. BK polyoma virus infection and renal disease in non-renal solid organ transplantation.

    Kuppachi, Sarat; Kaur, Deepkamal; Holanda, Danniele G; Thomas, Christie P


    BK virus (BKV) is a non-enveloped DNA virus of the polyomaviridae family that causes an interstitial nephritis in immunosuppressed patients. BKV nephropathy is now a leading cause of chronic kidney disease and early allograft failure following kidney transplantation. It is also known to cause renal disease with a progressive decline in kidney function in non-renal solid organ transplant (NRSOT) recipients, although the disease may not be recognized nor its impact appreciated in this patient population. In this report, we review the existing literature to highlight our current understanding of its incidence in NRSOT populations, the approaches to diagnosis and the potential treatment options.

    Raheem OA, Kamel MH, Daly PJ, Mohan P, Little DM, Awan A, Hickey DP. Mycophenolate mofetil in pediatric renal transplantation: A single center experience. Pediatr Transplantation 2011: 15:240-244. © 2009 John Wiley & Sons A\\/S. Abstract:  We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

    Objective: To explore the characteristic of operation, intra-operation treatment and the application of immunosuppressant in pediatric renal transplantation in order to improve therapeutic effectiveness. Methods: From March 1986 to October 2006, the clinical data of 63 children who underwent renal transplantation in our hospital were retrospectively analyzed. Results: The 1-, 3-, 5-, 10-year graft survival rates were 98.4%, 90.5%, 88.9% and 68.3%,respectively. And the corresponding patient survival rates were 100%, 95.2%, 92.1%, 71.4%. The body weight increased 4 to 12 kg and the body height grew up 2 to 6 cm during the first year post-transplantation. The main complications in the first year post-transplantation were hypertension (26/63, 41.3%), crinosity (14/63, 22.2%),drug-induced hepatic injury(11/63, 17.5%), gingival hyperplasia (10/63, 15.8%), pulmonary infection(9/63, 14.3%),bone marrow suppression(5/63, 7.9%), herpes (4/63, 6.3%) and diabetes (3/63, 4.8%). Conclusion: Renal transplantation is a preferred method for the treatment of children in end-stage renal disease (ESRD). Good tissue matching, proper operative time and pattern, peri-operactive care were essential to success, as well as appropriate immuno-suppressant strategy and good compliance.

  13. 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.

  14. Different Impact of Pretransplant Anti-HLA Antibodies Detected by Luminex in Highly Sensitized Renal Transplanted Patients

    Isabel Pérez-Flores; Jose Luis Santiago; Natividad Calvo-Romero; Alberto Barrientos-Guzmán; Ana Isabel Sánchez-Fructuoso


    It is well know that anti-HLA antibodies are an important obstacle in kidney transplantation. Our aim was to study the clinical impact of pretransplant donor specific anti-HLA antibodies (HLA-DSA), in highly sensitized (HS) patients. We analyzed retrospectively the day-of-transplant sera by Luminex Single Antigen Assay (LSA) in HS patients, and the results were correlated with episodes of humoral and cellular rejection as well as with graft and patient survival. All HS subjects received the s...

  15. 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.

  16. 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.

  17. Invasive filamentous fungal infections associated with renal transplant tourism.

    Shoham, S; Hinestrosa, F; Moore, J; O'Donnell, S; Ruiz, M; Light, J


    'Transplant tourism,' the practice of traveling abroad to acquire an organ, has emerged as an issue in kidney transplantation. We treated a patient who developed invasive aspergillosis of the allograft vascular anastomosis after receiving a kidney transplant in Pakistan, prompting us to review the literature of invasive mycoses among commercial organ transplant recipients. We reviewed all published cases of infections in solid organ transplant recipients who bought their organs abroad and analyzed these reports for invasive fungal infections. Including the new case reported here, 19 cases of invasive fungal infections post commercial kidney transplant occurring in 17 patients were analyzed. Infecting organisms were Aspergillus species (12/19; 63%), Zygomycetes (5/19; 26%), and other fungi (2/19; 5%). Invasive mold infections were present at the transplanted graft in 6/17 patients (35%) with graft loss or death in 13/17 (76%) of patients and overall mortality (10/17) 59%. Invasive fungal infections, frequently originating at the graft site, have emerged as a devastating complication of commercial renal transplant and are associated with high rates of graft loss and death.

  1. 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

  2. Severe Legionnaire's disease caused by Legionella longbeachae in a long-term renal transplant patient: the importance of safe living strategies after transplantation.

    Wright, A J; Humar, A; Gourishankar, S; Bernard, K; Kumar, D


    Legionella species are intracellular gram-negative bacilli that require specific culture media for growth. Transplant recipients with impaired cellular immunity are at particular risk for infection with this pathogen. Most human disease is caused by Legionella pneumophila; disease caused by non-L. pneumophila species is reported mainly in immunosuppressed patients with the exception of Legionella longbeachae. L. longbeachae is a common cause of Legionnaires' disease in Australia and New Zealand, and is associated with exposure to potting soil. We report the case of a patient, 26 years post kidney transplant, who presented with severe and rapidly progressive respiratory illness. L. longbeachae serogroup 1 was isolated from respiratory cultures. Further investigation revealed that she had significant soil exposure before the onset of illness. We highlight the importance of following safe living strategies to prevent exposure-related illness even in long-term transplant recipients. © 2012 John Wiley & Sons A/S.

  3. Invasive fungal infections in renal transplant recipients.

    Badiee, Parisa; Alborzi, Abdolvahab


    Invasive fungal infections are a significant and often lethal problem in transplant patients. Infections caused by geographically limited endemic fungi are infrequent, and Aspergillus species, Mucorales species, Candida species, and Cryptococcus neoformans are the opportunistic fungi responsible for most such infections. The symptoms of systemic fungal infections are nonspecific, particularly in their early stages. The high rates of mortality and graft loss owing to fungal infections render early diagnosis and treatment imperative in immunosuppressed patients. Current methods for the diagnosis of systemic fungal infections include imaging procedures, endoscopic methods and biopsies, microscopic and culture techniques, antibody and antigen-based serologic testing, and the detection (via polymerase chain reaction) of fungal deoxyribonucleic acid in blood or bronchoalveolar lavage fluid, as well as the careful analysis of signs and symptoms. Antifungal therapy should be initiated early in patients with a suspected fungal infection (even before laboratory findings have confirmed that diagnosis) and should be administered with appropriate adjustment of immunosuppressive regimens. To manage fungal infections in patients with renal failure, optimizing the pharmacokinetics of antifungal drugs to reduce the risk of nephrotoxicity is crucial.

  4. 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.

  5. GU Evaluation and Management of Renal Transplant Candidates and Recipients

    Peter N. Bretan


    Full Text Available There are more than 200,000 end stage renal disease (ESRD patients who are potential transplant candidates and more than 100,000 previously transplanted renal recipients with functioning allografts in the United States 1. Fifty-seven percent of these patients are male and forty percent are greater than 50 years of age 2, 3. Diabetes is the most common cause of kidney failure. It is evident that many patients are at high risk for development of urologic problems and thus it is estimated that the average urologist will care for up to ten of these patients yearly4. Thus a review of the genitourinary (GU evaluation and management of these patients is timely.

  6. Spontaneous Clearance of Hepatitis C after Liver and Renal Transplantation

    CH Dale


    Full Text Available Spontaneous clearance of hepatitis C virus (HCV is rare in immunocompromised patients, such as those who have undergone organ transplantation. It has been recognized that patients receiving liver transplantation for HCV-related disease have decreased graft and patient survival compared with those transplanted for other etiologies. There is a growing trend toward treating HCV recurrence aggressively after liver transplantation. For other organ transplant recipients with concurrent HCV, treatment is not often an option, given the high rates of graft rejection and loss secondary to interferon and its immunomodulatory effects. Although spontaneous clearance of HCV has been reported in recipients of solitary liver and renal transplants, a common factor arising in these cases has been previous exposure to interferon. To date, no reports of spontaneous clearance of HCV RNA have been reported in a multiorgan transplant recipient. A case of spontaneous clearance of HCV RNA in an immunocompromised patient, within five months of simultaneous liver and kidney retransplantation is described. Importantly, this patient had no previous exposure to interferon.

  7. 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.

    Fernandes, Paula Frassinetti Castelo Branco Camurça; Siqueira, Reed André; Girão, Evelyne Santana; Siqueira, Rainne André; Mota, Márcia Uchoa; Marques, Leyla Castelo Branco Fernandes; Andrade, Silvana Cristina Albuquerque; Barroso, Wilson Mendes; Silva, Sônia Leite; Rodrigues dos Santos, Bruno Gomes; de Oliveira, Claúdia Maria Costa


    AIM To present clinical characteristics from renal transplant recipients with dengue fever and its impact on graft function. METHODS We retrospectively evaluated 11 renal transplant recipients (RTR) with dengue infection confirmed by laboratory test, between January 2007 and July 2012, transplanted in the Renal Transplant Center of Walter Cantídio University Hospital from Federal University of Ceará. RESULTS Positive dengue serology (IgM) was found in all patients. The mean time between transplant and dengue infection was 43 mo. Fever was presented in all patients. Nine patients presented with classical dengue and two (18%) with dengue hemorrhagic fever. All cases had satisfactory evolution with complete recovery of the symptoms. The time for symptom resolution varied from 2 to 20 d, with an average of 9 d. An increase of creatinine after the infection was observed in three (27.2%) patients with no clinically impact on the kidney graft function. CONCLUSION RTR with dengue infection seems to have a clinical presentation and evolution similar to those seen in the general population, with no long-term damage to patient and to the graft.

  9. Sexuality, fertility, and renal transplantation: a survey of survivors.

    Schover, L R; Novick, A C; Steinmuller, D R; Goormastic, M


    A questionnaire on sexual function and fertility was completed by 54 men and 36 women, at an average of 3 years after successful renal transplant. Sexual desire increased significantly compared to reports of levels 6 months pretransplant. Men also had improved erectile function and ability to reach noncoital orgasms. About a quarter of men and women remained sexually dysfunctional, however. The frequency of sexual activity and overall sexual satisfaction did not improve significantly. Marital status and satisfaction were in the normal range for this group, except that those who became ill before adulthood were less likely to have married or have had children. Infertility was a major concern for 10% of the sample. Regular menstrual cycles were present in 64% of women under age 50, representing a significant improvement after transplantation. Three men fathered a child and two women became pregnant after transplantation. Most patients wanted more information on sexuality, fertility, and renal disease.

  10. Urinary tract infections and asymptomatic bacteriuria in renal transplant recipients

    Rabi Yacoub


    Full Text Available Asymptomatic bacteriuria and urinary tract infection are common complications after kidney transplantation. In this population, if urinary tract infection occurred in the first six months post procedure, it carries a grave impact on both graft and patient survival. Renal transplant recipients with urinary tract infection are often clinically asymptomatic as a consequence of immunosuppression. Urinary tract infection, however, may progress to acute pyelonephritis, bacteremia and the full blown picture of urosepsis. PubMed and Cochrane databases were searched. The purpose of this review is to discuss the screening and treatment of urinary tract infection and asymptomatic bacteriuria in renal transplant recipients and to evaluate the guidelines on the basis of a review of published evidence.

  11. Outcomes of Renal Transplantation in HIV-1 Associated Nephropathy.

    Sana Waheed

    Full Text Available Several studies have demonstrated that renal transplantation in HIV positive patients is both safe and effective. However, none of these studies have specifically examined outcomes in patients with HIV-associated nephropathy (HIVAN.Medical records of all HIV-infected patients who underwent kidney transplantation at Johns Hopkins Hospital between September 2006 and January 2014 were reviewed. Data was collected to examine baseline characteristics and outcomes of transplant recipients with HIVAN defined pathologically as collapsing focal segmental glomerulosclerosis (FSGS with tubulo-interstitial disease.During the study period, a total of 16 patients with HIV infection underwent renal transplantation. Of those, 11 patients were identified to have biopsy-proven HIVAN as the primary cause of their end stage renal disease (ESRD and were included in this study. They were predominantly African American males with a mean age of 47.6 years. Seven (64% patients developed delayed graft function (DGF, and 6 (54% patients required post-operative dialysis within one week of transplant. Graft survival rates at 1 and 3 years were 100% and 81%, respectively. Acute rejection rates at 1 and 3 years were 18% and 27%, respectively. During a mean follow up of 3.4 years, one patient died.Acute rejection rates in HIVAN patients in this study are higher than reported in the general ESRD population, which is similar to findings from prior studies of patients with HIV infection and ESRD of various causes. The high rejection rates appear to have no impact on short or intermediate term graft survival.

  12. Uncommon side effect of MMF in renal transplant recipients.

    Balal, M; Demir, E; Paydas, Saime; Sertdemir, Y; Erken, U


    Mycophenolate mofetil (MMF) is a potent immunosuppressive agent used in renal transplantation. Gastrointestinal and hematological side effects are commonly observed, but hepatotoxicity has not been reported. In this study, we assessed MMF-related hepatotoxicity in renal transplant recipients. A total of 124 renal transplantation recipients (RTRs) were evaluated for elevated liver enzymes associated with MMF, and 79 patients were enrolled to the study. Patients used MMF 2 g/day. The patients who had progressive increase in liver enzymes after renal transplantation and their AST, ALT, GGT, ALP, bilirubin levels, hepatitis, cytomegalovirus (CMV), abdominal ultrasonography, duration of hepatotoxicity, and decreased dosage or withdrawal of MMF were recorded. Also, we evaluated their liver enzymes while the patients were on the waiting list. Of the 79 patients, 11 patients (13.9%) had a progressive increase in liver enzymes. The median (min-max) age of the patients with MMF-hepatotoxicity was 29 (19-54) and 72.7% of them were male. None of the patients had hepatitis B or C, CMV infection, or other possible causes for elevated liver enzymes and their abdominal ultrasonography were normal. High liver enzyme levels regressed after the withdrawal (n=6) or reduce dosage (n=5) of MMF. The median time of the increase in liver enzymes was 28 (4-70) days and after 50% reduction or withdrawal of MMF, returned to normal values in 16 (4-210) days. The median levels of ALT in waiting list (I), before (II), and after (III) reduction dosage or withdrawal of MMF were 22.0 (3-22), 222.0 (51-508), and 33.0 (21-64) U/L, respectively (p I-II=0.004,p I-II=0.013, andp II-III=0.005). There were no differences for ALP, GGT, total bilirubin, and direct bilirubin levels. Also, the correlation between recovery time of ALT and persistence time of ALT elevation before adjustment of MMF was significant (r=0.739, p=0.009). Consequently, after renal transplantation, hepatotoxicity can occur due to a

  13. "A fine needle aspiration cytology in time saves nine" - cutaneous phaeohyphomycosis caused by Exophiala jeanselmei in a renal transplant patient: Diagnosis by fine needle aspiration cytology

    Prashant Joshi


    Full Text Available Infections by dematiaceous fungi are an emerging group of infectious diseases worldwide with a variety of clinical presentations. Though generally localized, they can disseminate in immunocompromised settings, therefore, early diagnosis and prompt therapy can prevent significant morbidity and mortality in these patients. Fungi of genus Exophiala are common causative organisms; however, Exophiala jeanselmei (E. jeanselmei has not yet been reported from environmental sources in India. We present here the case of a renal transplant recipient who presented with an innocuous lesion on the foot, diagnosed on fine needle aspiration cytology (FNAC as phaeohyphomycosis, and promptly treated with excision and antifungal therapy. To the best of our knowledge, this is the first case report from India of E. jeanselmei causing phaeohyphomycosis in a transplant recipient and highlights the role a cytopathologist can play in the timely management of such cases.

  14. Cadaver renal transplant outcome in recipients with autolymphocytotoxic antibodies.

    Ettenger, R B; Jordan, S C; Fine, R N


    The major impact of autolymphocytotoxic antibodies (ALCA) on renal transplantation has been in the interpretation of the pretransplant crossmatch as a cause of false-positive results. Less attention has been paid to the direct affects of ALCA on renal allografts. We have examined the sera of 38 recipients of 41 cadaver renal allografts for the presence of ALCA. There were 9 patients with ALCA who received 10 allografts. In these allografts with ALCA, actuarial graft survival was significantly improved (P less than 0.05) over that of 31 transplants without ALCA. In recipients with ALCA, graft survival was 90% at six months and 60% at one and two years; in recipients without ALCA, graft survival was 48% at six months, 35% at one year and 24% at two years. ALCA may be exerting graft-enhancing properties by means of an autoregulatory effect upon the recipient's immunologic system.

    textabstractThe incidence of osteonecrosis was 24% in 248 patients who had received 262 kidney transplants 1971-1982. However, based only on patients at risk, i.e. alive with functioning transplants, the incidence at 1, 3 and 6 years was found to be 13, 27 and 36%; after six years no new cases were

  16. HLA polymorphisms as incidence factor in the progression to end-stage renal disease in Brazilian patients awaiting kidney transplant.

    Crispim, J C; Mendes-Júnior, C T; Wastowski, I J; Palomino, G Martelli; Saber, L T; Rassi, D M; Donadi, E A


    Chronic renal failure (CRF) leads in the majority of instances to end-stage renal disease (ESRD) requiring renal replacement therapy. Age, gender, genetics, race, hypertension, and smoking among others are factors associated with ESRD. Our interest was to evaluate the possible associations of class I and II HLA antigens with ESRD renal disease independent of other factors, among patients with CRF, having various diagnoses in the Brazilian population of the São Paulo state. So 21 HLA-A, 31 HLA-B, and 13 HLA-DR were detected in 105 patients who were compared with 160 healthy controls of both sexes who were not related to the patients evaluated until 2005. We calculated allelic frequencies, haplotypes frequencies, etiological fractions (EF), preventive fractions, and relative risks (RR). We compared demographic data of patients and controls. The antigens positively associated with ESRD were: HLA-A78 (RR = 30.31 and EF = 0.96) and HLA-DR11 (RR = 18.87 and EF = 0.65). The antigens HLAB14 (RR = 29.90 and EF = 0.75) was present at a significantly lower frequency among patients compared with controls. In contrast, no haplotype frequency showed statically significant associations. Further molecular studies may clarify types and subtypes of alleles involved with ESRD progression.

  17. 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.

  18. [Post-renal transplant pregnancy: a project to plan carefully].

    Trubian, Alessandra; Zaza, Gianluca; Rugiu, Carlo; Tomei, Paola; Lupo, Antonio


    Kidney transplant is the best treatment for end-stage renal disease (ESRD) as it improves the quality of life and reduces the mortality risk for most patients compared with maintenance dialysis. Additionally, evidence from the literature suggests that renal function, endocrine status and libido rapidly improve after kidney transplant, and one in 50 women of childbearing age become pregnant. Therefore, it seems clear that pregnancy after transplant is a great challenge for physicians involved in this field. The available information on pregnancy outcomes is largely derived from case reports and single-center series, which are unlikely to be representative. Moreover, poor results are less likely to be reported. Many of the reports on long-term outcome show the results of past medical, obstetric, and neonatal care, which may be very different from current practice. Attempts are being made to provide more up-to-date, representative data through national transplantation pregnancy registries. A great number of researchers worldwide have analyzed the biological and endocrinological machinery associated with this event. Additionally, several strategies have been introduced to avoid unplanned pregnancies and to minimize maternal and fetal complications in renal transplant recipients. It seems evident that the return to fertility soon after transplant is often associated with unplanned pregnancy, which can expose both mother and fetus to considerable risks. This underpins the necessity to recommend contraceptive counseling and start clinical follow-up in order to early identify possible pregnancy-related risk factors. In general, pregnancy should not be recommended within the first year after kidney transplant because the risk of acute rejection is greatest and immunosuppressive therapy the most aggressive. It should be planned when organ function and immunosuppressive therapy are stabilized and there is no sign of rejection, hypertension, or chronic infection. Additionally

  19. 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.

  20. Incidence of Recurrent Urinary Tract Infection after Renal Transplantation

    MohammadReza Pourmand


    Full Text Available Background: The pathologies classified as urinary tract infections (UTI can have a deleterious effect on patients who have undergone a renal transplantation.  Often recurrent UTIs will occur, leading to high morbidity, failure of the grafting process overall and even death.  The study presented here seeks to expand the knowledge of recurrent UTIs in the context of renal transplantation, what risks recurrent UTIs pose to transplant patients and evaluate possible treatments.Methods: Renal transplantations were performed on 94 patients.   For six months post-surgery the patients were evaluated for the presence of recurrent UTIs.  The criteria for determining a patient as having a UTI was given as finding   more than 103    and 105  pure colonies within one ml of urine for asymptomatic and symptomatic patients, respectively.   The criteria of recurrent UTI was defined as two or more conclusive UTIs within the first six months after the surgery or three more within a year after renal transplantation.Results: Of the 94 hospitalized patients, 29 UTIs were diagnosed (30.8%. The majority of diagnosed UTIs were in female patients (11.15, 73.3% vs.4.15, 26.7%; p-value = 0.003.   Those patients with diabetes mellitus correlated with a better chance of having a UTI (p-value = 0.019; CI = 1.2-12.2. The incidence rate of UTI was 51.7%, female predominant 73.3%. No  other  pathologies  were  shown  to  affect  the  chance  of  developing recurrent UTIs.   Typically Escherichia coli was the bacterium isolated fromurine  cultures  (48.3%  from  those  who  developed  recurrent  UTI.    The isolates tended to possess resistance to TMP / SMX and piperacillin but weresusceptible to imipenem.Conclusion:   Recurrent UTIs in renal transplant patients can be mitigated with proper identification of risk factors.

  1. Glomerular Filtration Rate Estimation in Renal and Non-Renal Solid Organ Transplantation

    Hornum, Mads; Feldt-Rasmussen, Bo


    Following transplantation (TX) of both renal and non-renal organs, a large proportion of patients have renal dysfunction. There are multiple causes for this. Chronic nephrotoxicity and high doses of calcineurin inhibitors are important factors. Preoperative and perioperative factors like...... hypertension, hypotension, drugs and infections may play a causative role as well. Organ-specific causes include hepatorenal syndrome, cirrhosis, low cardiac function, low respiratory function and diabetes developed both before and after TX. It is important to be able to perform precise and valid measurements...

  2. 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.

  3. Criteria for and Appropriateness of Renal Transplantation in Elderly Patients With End-Stage Renal Disease: A Literature Review and Position Statement on Behalf of the European Renal Association-European Dialysis and Transplant Association Descartes Working Group and European Renal Best Practice.

    Segall, Liviu; Nistor, Ionuţ; Pascual, Julio; Mucsi, Istvan; Guirado, Lluis; Higgins, Robert; Van Laecke, Steven; Oberbauer, Rainer; Van Biesen, Wim; Abramowicz, Daniel; Gavrilovici, Cristina; Farrington, Ken; Covic, Adrian


    During the last 20 years, waiting lists for renal transplantation (RT) have grown significantly older. However, elderly patients (ie ≥65 years of age) are still more rarely referred or accepted to waiting lists and, if enlisted, have less chances of actually receiving a kidney allograft, than younger counterparts. In this review, we looked at evidence for the benefits and risks of RT in the elderly trying to answer the following questions: Should RT be advocated for elderly patients? What should be the criteria to accept elderly patients on the waiting list for RT? What strategies might be used to increase the rate of RT in waitlisted elderly candidates? For selected elderly patients, RT was shown to be superior to dialysis in terms of patient survival. Virtually all guidelines recommend that patients should not be deemed ineligible for RT based on age alone, although a short life expectancy generally might preclude RT. Concerning the assessment of comorbidities in the elderly, special attention should be paid to cardiac evaluation and screening for malignancy. Comorbidity scores and frailty assessment scales might help the decision making on eligibility. Psychosocial issues should also be evaluated. To overcome the scarcity of organ donors, elderly RT candidates should be encouraged to consider expanded criteria donors and living donors, as alternatives to deceased standard criteria donors. It has been demonstrated that expanded criteria donor RT in patients 60 years or older is associated with higher survival rates than remaining on dialysis, whereas living donor RT is superior to all other options.

  4. [Estimate of the needs in renal transplantation in Morocco].

    Boly, Ahmadou; El Hassane Trabelsi, Mohamed; Ramdani, Benyounes; Bayahia, Rabea; Benghanem Gharbi, Mohamed; Boucher, Stéphanie; El Berri, Hicham; Nejjari, Chakib; Couchoud, Cécile


    Kidney transplantation is still underdeveloped in Morocco. In order to anticipate needs and discuss a possible reorganization of the provision of care, an estimate of the number of patients who would benefit from kidney transplant was conducted. This study was done in two steps. During the first step, based on the French renal replacement therapy registry (Rein), we develop a prediction score based on the likelihood of being treated by an autonomous dialysis (hemodialysis in self-care unit or peritoneal dialysis non-assisted by a nurse) and be registered on the national kidney transplant waiting list. During the second step, we apply this score to the data of the registry Magredial (Moroccan registry of renal replacement therapy, deployed in seven regions). Twelve parameters were related to autonomy and registration on the waiting list. Each of these parameters has been assigned a weight. Each patient was assigned a number of points, sum of different weights. By retaining a threshold of 21 points (80% specificity), 2260 subjects (57%) had a score less than or equal to this threshold in Magredial. With a number of patients on dialysis in Morocco estimated to 13,000 in late 2013, the estimated need for kidney transplant will be of 7410. This estimate should encourage professionals and health authorities of Morocco to engage more effort in the implementation of actions related to the transplant program.

  5. Renal transplantation vs hemodialysis: Cost-effectiveness analysis

    Perović Saša


    Full Text Available Background/Aim. Chronic renal insufficiency (CRI, diabetes, hypertension, autosomal dominant polycystic kidney disease (ADPKD are the main reasons for starting dialysis treatment in patients having kidney function failure. At present, dialysis treatments are performed in about 4,100 patients at 46 institutions in Serbia, out of which 90% are hemodialyses. At end-stage renal disease (ESRD the only correct selection is kidney transplatation. The basic aim of the planned research was to compare ratio of costs and effects (Cost Effectiveness Analysis - CEA of hemodialysis and kidney transplantation in patients at ESRD. Methods. As the main issue of treatment in patients from both groups the life quality measured by the validated McGill Questionary, was used. The study included 150 patients totally, divided into two groups. The study group consisted of 50 patients with kidney transplantation performed at the Clinical Center of Serbia and the control group consisted of 100 patients on hemodialysis at Clinical Center of Serbia, Clinical Hospital Center Zemun, Clinical Hospital Center 'Zvezdara', Clinical Center Kragujevac and Health Center 'Studenica', Kraljevo, comparable with respect to sex, age and length of treatment with the study group. Results. Effect of kidney transplantation in relation to hemodialysis being selection of treatment is expressed in the form of incremental ratio of costs and effects (Incremental Cost-Effectiveness Ratio - ICER. It is clear from the enclosed tables that the strategy of kidney transplantation is far more profitable considering the fact that it represents saving of EUR 132,256.25 per one year of contribution Quality Adjusted Life Years (QALY within the period of 10 years. According to all aspects of live quality (physical symptoms and problems, physical well-being, psychological symptoms, existential well-being and support, difference is statistically important in favor of transplant patents. Conclusion. The costs

  6. Infectious Alopecia in a Dog Breeder After Renal Transplantation

    Cheng-Hsu Chen


    Full Text Available Tinea capitis rarely occurs in renal transplant recipients. We report this living-related renal transplant patient receiving cyclosporine-based therapy who initially presented with severe exfoliation of the scalp with yellowish-white scales and marked hair loss. The lesions extended to the frontal area and both cheeks, resulting in several skin ulcers with perifocal erythematous inflammatory changes, and palpable cervical lymph nodes. A biopsy of a skin lesion revealed fungal infection and culture yielded Microsporum canis. The patient mentioned an outbreak of ringworm in her breeding dogs during this period. After adequate treatment of the patient and her infected animals with griseofulvin and disinfection of the environment, her skin lesions resolved dramatically, with regrowth of hair.

  8. Serum amylase activity and renal amylase activity clearance in patients with severely impaired renal function and in patients treated with renal allotransplantation.

    Pedersen, E B; Brock, A; Kornerup, H J


    Serum amylase activity was measured in 29 nondialysed patients with severe renal failure, in 24 uraemic patients treated with chronic haemodialysis, and in 29 patients treated with renal allotransplantation. Simultaneous measurement of renal amylase activity clearance (CAm) and creatinine clearance (CCr) was performed in 25 patients with severe renal failure and in 19 transplanted patients. Serum amylase activity was elevated in all three groups. CAm was significantly correlated to CCr both in the group with severe renal failure and in the transplanted group. Unlike in the group of transplanted patients, the ratio CAm/CCr was significantly increased in patients with severe impaired renal function. It is concluded that the elevation of serum amylase activity in patients with impaired renal function is primarily due to decreased glomerular filtration rate. The value of CAm/CCr for diagnosing acute pancreatitis is doubtful in patients with severe renal disease.

    Yoon, Yeo Chang; Shin, Byung Seok; Ohm, Joon Young; Kim, Seong Min; Ahn, Moon Sang; Yang, Shin Seok [Chungnam National University Hospital, Daejeon (Korea, Republic of); Park, Mi Hyun [Dept. of Radiology, Dankook University Hospital, Cheonan (Korea, Republic of)


    To compare the usefulness of Doppler ultrasonography and renal scintigraphy in the assessment of short- and long-term function of transplanted kidneys. We retrospectively reviewed the cases of 79 patients who underwent Doppler ultrasonography and technetium-99m diethylene triamine pentaacetic acid renal scintigraphy on the same day, within 4 days of renal transplantation. Image parameters were evaluated for statistical differences. There was a strong positive correlation between the glomerular filtration rate (GFR) as measured by renal scintigraphy and the estimated GFR (eGFR) based on serum creatinine levels (correlation coefficient = 0.71). Scan grade according to the time-activity curve, resistive index, and end diastolic velocity showed moderate correlations with the eGFR (correlation coefficients = -0.557, -0.329, and 0.370, respectively) in the early post-transplantation period. The mean survival time was longer in patients with lower resistive indices (≤ 0.68, 54.9 months vs. > 0.68, 29.5 months) and lower pulsatility indices (≤ 1.32, 53.8 months vs. > 1.32, 28.7 months); however, there were no statistically significant differences in the long-term follow-up period (p = 0.121 for resistive index and p = 0.074 for pulsatility index). Renal scintigraphy is a more sensitive method than Doppler ultrasonography for assessing transplanted kidney function in the early post-transplantation period. Doppler ultrasonography might reflect the long-term survival time. However, it is difficult to predict long-term renal function using either method.

  11. 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

  12. [BK virus infection in a pediatric renal transplant recipient].

    Bonaventura, R; Vázquez, A; Exeni, A; Rivero, K; Freire, M C


    BK Human Polyomavirus causes an asymptomatic primary infection in children, then establishing latency mainly in the urinary tratt. Viral reactivation can lead to renal pathology in individuals with impaired cellular immune response. This is particularly important in pediatric transplant recipients, who can suffer a primary infection when immunosupressed. We followed up the case of a 5 years old patient who received a renal transplant in October 2003, and presented damaged graft 45 days after the intervention. The patient suffered 3 episodes of renal function failure between October 2003 and June 2004. Blood, urine, renal biopsy and lymphocele liquid samples were analyzed. A differential diagnosis between acute rejection and infectious causes was established by testing for BK, CMV and ADV viruses, and the cytological study of renal tissue. Laboratory findings together with clinical signs suggest the patient was infected by BK virus. As a final consideration, the great importance of differentiating between acute rejection and BK infection is emphasized, since immunosuppressant management is opposite in each case.

  13. Robot Assisted Renal Auto Transplantation: A Case Based Discussion of Unique Anaesthetic Considerations

    Praveen Gupta


    Full Text Available Laparoscopic renal autotransplantation has serious perturbations on the body's homeostasis due to its non physiological positioning, use of pneumoperitoneum, changing fluid strategy at different points of time and on-going steps to maintain optimal environment for the transplanted kidney. Generally speaking, the anaesthetic management of renal auto-transplantation by open technique is not very complex and the perioperative management can be categorized in the intermediate level of clinical skill requirement. Adding to the comfort of the anaesthesiologist is the fact that these patients are not in end stage renal disease state and does not manifest the comorbidities, multisystem involvement and technical complexities of long term renal dysfunction and renal replacement therapy. In our case report surgeons used the da Vinci surgical robotic system for laparoscopic transplantation of the kidney at a new site. In this article we discuss the anaesthetic challenges of robot assisted laparoscopic renal auto-transplantation along with a description of our index case.

    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.

  16. 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.

  17. Hemolytic uremic syndrome recurrence after renal transplantation.

    Loirat, Chantal; Fremeaux-Bacchi, Véronique


    About 60% of non-Stx-associated aHUS are due to the defect of protection of endothelial cells from complement activation, secondary to mutations in the genes of CFH, MCP, IF, BF, or C3. In addition, 10% of patients have anti-CFH antibodies. While the risk of post-transplant recurrence is less than 1% in Stx-HUS patients, it is approximately 80% in CFH or IF-mutated patients, 20% in MCP-mutated patients, and 30% in patients with no mutation. Patients with anti-CFH antibodies probably also are at risk of recurrence. While MCP-mutated patients can reasonably go to transplantation, recent reports suggest that plasmatherapy started before surgery and maintained life-long may prevent recurrence in CFH-mutated patients. Four successful liver-kidney transplantation utilizing plasmatherapy in CFH-mutated children have been reported recently. In summary, the risk of post-transplant recurrence can now be approached according to genotype. Therefore, aHUS patients should undergo complement determination, screening for anti-CFH antibodies, and genotyping before transplantation. Kidney or kidney + liver transplantation with concomitant plasmatherapy need to be evaluated by prospective trials in patients with hereditary complement abnormalities.

  18. Transjugular renal biopsy in the treatment of patients with cirrhosis and renal abnormalities.

    Jouët, P; Meyrier, A; Mal, F; Callard, P; Guettier, C; Stordeur, D; Trinchet, J C; Beaugrand, M


    When renal lesions are suspected in patients with cirrhosis, clotting disorders often preclude percutaneous renal biopsy. This study was undertaken to determine whether transjugular renal biopsy is possible, safe, and useful in such patients. From 1987 to 1994, 70 patients with cirrhosis and clotting disorders underwent transjugular renal biopsies, providing renal tissue in 55. Of these 55 patients, 41 were Child-Pugh class B or C, 35 were alcoholic, serum creatinine levels were > or = 130 micromol/L in 46, and proteinuria was > or = 0.5 g/d in 37. Clinically significant complications of transjugular renal biopsy were persistent hematuria in 4 and perirenal hematoma in 4, requiring blood transfusions in 1 and 2 cases, respectively. There were no deaths related to renal biopsy. Renal lesions were identified as glomerular in 41 (74.5%), interstitial in 7, and end-stage in 2 and were absent in 5. Transjugular renal biopsy influenced treatment in 21 patients (38%), including 11 who were proposed for liver transplantation and 4 who had chronic liver rejection. Decisions based on results of transjugular renal biopsy were to perform liver transplantation in 8 and combined renal and liver transplantation in 5, whereas 2 were refused. In 6 other patients, the results of renal biopsy modified the medical regimen. We conclude that transjugular renal biopsy may be a useful procedure in patients with cirrhosis and clotting disorders. This technique does not entail undue risks and may influence treatment decisions, particularly in patients proposed for liver transplantation.

  20. Type 4 renal tubular acidosis in a kidney transplant recipient

    Manjunath Kulkarni


    Full Text Available We report a case of a 66-year-old diabetic patient who presented with muscle weakness 2 weeks after kidney transplantation. Her immunosuppressive regimen included tacrolimus, mycophenolate mofetil, and steroids. She was found to have hyperkalemia and normal anion gap metabolic acidosis. Tacrolimus levels were in therapeutic range. All other drugs such as beta blockers and trimethoprim – sulfamethoxazole were stopped. She did not respond to routine antikalemic measures. Further evaluation revealed type 4 renal tubular acidosis. Serum potassium levels returned to normal after starting sodium bicarbonate and fludrocortisone therapy. Though hyperkalemia is common in kidney transplant recipients, determining exact cause can guide specific treatment.

    Bavanandan, Sunita; Yap, Yok-Chin; Ahmad, Ghazali; Wong, Hin-Seng; Azmi, Soraya; Goh, Adrian


    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.

  5. 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.

  7. De Novo Fibrillary Glomerulonephritis (FGN in a Renal Transplant with Chronic Hepatitis C

    Edward J. Filippone


    Full Text Available Chronic hepatitis C viremia (HepC has been associated with numerous renal manifestations both in native kidneys and in the setting of renal transplantation. Glomerulonephritis (GN of the renal allograft in the setting of HepC most commonly manifests as type 1 membranoproliferative GN (MPGN, either representing recurrence of the original disease or arising de novo. Other GNs were reported after transplantation in the patient with HepC including membranous nephropathy and thrombotic microangiopathy, as well as an enhanced susceptibility to transplant glomerulopathy. We describe the first case of de novo fibrillary GN in a renal transplant patient with HepC where the primary renal disease was biopsy proven type 1 MPGN. We discuss this relationship in detail.

  8. A simple and accurate grading system for orthoiodohippurate renal scans in the assessment of post-transplant renal function

    Zaki, S.K.; Bretan, P.N.; Go, R.T.; Rehm, P.K.; Streem, S.B.; Novick, A.C. (Cleveland Clinic Foundation, OH (USA))


    Orthoiodohippurate renal scanning has proved to be a reliable, noninvasive method for the evaluation and followup of renal allograft function. However, a standardized system for grading renal function with this test is not available. We propose a simple grading system to distinguish the different functional phases of hippurate scanning in renal transplant recipients. This grading system was studied in 138 patients who were evaluated 1 week after renal transplantation. There was a significant correlation between the isotope renographic functional grade and clinical correlates of allograft function such as the serum creatinine level (p = 0.0001), blood urea nitrogen level (p = 0.0001), urine output (p = 0.005) and need for hemodialysis (p = 0.007). We recommend this grading system as a simple and accurate method to interpret orthoiodohippurate renal scans in the evaluation and followup of renal allograft recipients.

  13. Nonobstructing Colonic Dilatation and Colon Perforations Following Renal Transplantation

    Koneru, Baburao; Selby, Rick; O’Hair, Daniel P.; Tzakis, Andreas G.; Hakala, Thomas R.; Starzl, Thomas E.


    Nonobstructing colonic dilatation has not been commonly reported following renal transplantation, and colon perforations carry a high morbidity and mortality in this population. During a 7-year period, nonobstructing colonic dilatation developed in 13 adults 1 to 13 days after renal transplantation. Twelve (92%) of the 13 had poorly functioning allografts. Five (83%) of the 6 with and 2 (29%) of the 7 without colonoscopy had resolution of nonobstructing colonic dilatation. Of the seven right-sided colon perforations during this period, six were associated with nonobstructing colonic dilatation. An additional 4 patients had diverticular perforations in the left colon. Of a total of 11 patients with colon perforation, 7 had surgery within 24 hours of the perforation and 6 (86%) of these survived. Only 1 (25%) of the 4 having surgery more than 24 hours later survived. Six of the survivors retained functioning allografts. Nonobstructing colonic dilatation seems to be a potential complication of poor graft function after renal transplantation, and colonoscopy is effective in its treatment. In patients with colon perforations, early surgery and reduced immunosuppression are essential in decreasing mortality. PMID:2331220

    Almonte, Mavel; Velásquez-Jones, Luis; Valverde, Saúl; Carleton, Bruce; Medeiros, Mara


    PTE is defined as hematocrit >51% or hemoglobin >17 g/dL after renal transplantation. Risk factors include native kidneys with adequate erythropoiesis pretransplant, smoking, renal artery stenosis, and cyclosporine treatment. We report the case of a 14-yr-old female kidney transplant patient, with triple therapy immunosuppression and stable graft function who developed PTE at 12 months post-transplant with hemoglobin 17.3 g/dL, hematocrit 54.2%, stable graft function, and normotensive with normal cardiac echocardiogram and erythropoietin levels. The only risk factor found was tobacco use. As she had no spontaneous improvement, enalapril treatment was started at 19 months post-transplant with a hemoglobin level of 17.5 g/dL and hematocrit 53%; by 23 months post-transplant, hemoglobin lowered to 15 g/dL and hematocrit to 44.5% and continued to be in normal range thereafter. PTE is a rare condition in childhood and can be successfully treated with enalapril. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Renal failure is a frequent complication in liver transplant recipients and is associated with increased morbidity and mortality. A variety of risk factors for the development of renal failure in the pre- and post-transplantation periods have been described, as well as at the time of surgery. To reduce the negative impact of renal failure in this population, an active approach is required for the identification of those patients with risk factors, the implementation of preventive strategies, and the early detection of progressive deterioration of renal function. Based on published evidence and on clinical experience, this document presents a series of recommendations on monitoring RF in LT recipients, as well as on the prevention and management of acute and chronic renal failure after LT and referral of these patients to the nephrologist. In addition, this document also provides an update of the various immunosuppressive regimens tested in this population for the prevention and control of post-transplantation deterioration of renal function.

  18. Laparoscopic bilateral nephroureterectomy and bladder cuff excision for native renal pelvic and ureteral transitional cell carcinoma after renal transplantation.

    Chen C


    Full Text Available A 37-years-old female who was suffering from end-stage renal disease for about 6 years received allograft renal transplantation 4 years ago. She has been receiving 50mg of Cyclosporin A orally daily for immuno-suppression since then. Gross haematuria was noted and computerised tomography showed native left renal pelvic and ureteral multi-focal transitional cell carcinoma with severe hydronephrosis. Laparoscopic bilateral nephroureterectomy and bladder cuff excision were performed. In the past, history of previous operation was considered a relative contraindication for laparoscopic surgery. To our knowledge, we present the first case of laparoscopic treatment for native renal pelvic and ureteral transitional cell carcinoma after renal allograft transplantation without a hand-assisted device. This case shows the feasibility of laparoscopic bilateral nephroureterectomy in patients with transplanted kidneys.

    Background For the renal transplant recipients, anemia is one of the common complications and becomes a major medical issue before transplantation. Haemoglobin (Hb) is used as a prognostic indicator, although the optimal pre-transplantation Hb concentration associated with positive prognosis is still controversial. The aim of this study was to detect the optimal Hb concentration on predicting the graft survival and function.Methods A retrospective cohort study was conducted by reviewing the medical records of the patients who received renal transplantations at our center from January 2004 to June 2008. Patients were divided into two groups: high Hb group (>100 g/L, n=79) and low Hb group (<100 g/L, n=63). There was no significant difference between the two groups regarding sex, age, blood type and tissue types. Renal function among the two groups was measured and compared.Panel reacting antigens (PRA) of all the recipients were negative. The effect of preoperative hemoglobin concentration on the postoperative renal function recovery in both groups was further analyzed.Results A total of 14 acute rejection episodes occurred, including 5 patients in the high Hb group (7.9%) and 9 in the low Hb group (11.4%, P >0.05). The serum creatinine level at one-year post-transplantation of the low Hb group was significantly higher than that of the high Hb group ((117.8±36.3) μmol/L vs. (103.1±35.5) μmol/L, P <0.05). For one-year actuarial patient and graft survival, incidence of delayed graft function (DGF), serum creatinine concentrations at 1, 3, 6 months post-transplantation, the incidence of cytomegalovirus (CMV) infection, post-transplantation anemia (PTA) and post-transplantation diabetes mellitus (PTDM) of both groups, there were no statistically significant differences.Conclusion Pre-transplantation Hb concentration has significant effect on one-year creatinine concentration, but can not significantly affect acute rejection episodes, DGF, PTA, CMV infection

  20. 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.

  1. Pityriasis Versicolor on Penile Shaft in a Renal Transplant Recipient

    Ryu, Han-Won; Cho, Jae-We


    Pityriasis versicolor is a superficial infection of the stratum corneum, which is caused by the Malassezia species. Tge Malassezia species consist of 12 subspecies, including M. furfur, M. pachydermatis, M. symphodialis and M. globasa. The Malassezia species are classified as a normal flora, particularly in the sebum rich areas of the skin, and they convert from saprophytic yeast to parasitic mycelial morpholgic form to cause clinical disease. But majorities of their distributions are in the upper back, the neck, the thighs, and the forearm, and not in the penis. It is well known that the renal transplant patients, who take immunosuppressive agents, have impairment in the protective cell mediated immunity. Thus, they are more susceptible to infectious diseases, such as a fungal infection. Therefore, clinical manifestations show higher incidence of disease, but they mostly occur in an expected distribution. We here report a case of pityriasis versicolor in a renal transplant recipient on penile shaft, which is an unusual area. PMID:22879720

  3. Avoiding steroids in pediatric renal transplantation: long-term experience from a single centre

    Pedersen, Erik Bo; El-Faramawi, Mohamad; Foged, Nils


    We report our experience in pediatric renal transplantation avoiding steroids whenever possible. Immunosuppression consisted of an initial induction with antithymocyte globulin followed by maintenance therapy with a calcineurin inhibitor and MMF. Steroids were only given to selected patients......). Unfortunately PTLD occurred in three patients, but all survived with functioning grafts. Accordingly, our findings indicate that steroid avoidance in pediatric renal transplantation is possible with good results with respect to acute graft rejection as well as long-term graft survival....

    Jason Lee; Michael Ordon


    Robotic surgery has enabled surgeons to offer more patients a minimally invasive surgical option in the management of their complex diseases. While renal transplantation is associated with significant improvements in quantity and quality of life for most end-stage renal disease (ESRD) patients, it is also not devoid of its surgical risks and potential morbidities. Robotic-assisted kidney transplantation is a recently described, innovative application of the robotic surgery platform, and early...

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

    Nampoory, Naryanan; Gheith, Osama; Al-Otaibi, Torki; Halim, Medhat; Nair, Prasad; Said, Tarek; Mosaad, Ahmed; Al-Sayed, Zakareya; Alsayed, Ayman; Yagan, Jude


    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.

  6. Farmacodinâmica do cisatracúrio no transplante renal Farmacodinámica del cisatracúrio en el transplante renal Cisatracurium pharmacodynamics in renal transplantation

    Ismar Lima Cavalcanti


    : Cisatracurium seems to be beneficial, especially for patients with organ dysfunction, due to organ-independent Hofmann elimination and a lower trend to histamine release. This study aimed at determining cisatracurium pharmacodynamic profile in renal transplantation. METHODS: Participated in this study 30 patients who were distributed in two groups: 15 healthy patients submitted to maxillofacial surgery, and 15 patients with chronic renal failure submitted to renal transplantation. All patients were anesthetized with etomidate, sufentanil and 0.5% to 1% sevoflurane . Intravenous cisatracurium was administrated after anesthetic induction and additional 0.05 was injected whenever T1 recovered 25%. Neuromuscular function was continuously monitored by acceleromyography using TOF stimulation, through supramaximal ulnar nerve stimulation. RESULTS: Onset time (4.1 and 4.9 min, clinical duration (68.9 and 75.4 min and recovery time (20.2 and 28 min were similar between normal and renal failure groups, respectively. Time spent until T4/T1 > 0.7 (34.3 and 51.4 min, and > 0.9 (49.7 and 68.6 min since the last 25
