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

    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.

    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.

    The most effective primary treatment of chronic renal failure is renal transplantation. A significant improvement in lifestyle and family life in conjunction with it being an extremely cost-effective procedure has resulted in an intense monitoring and imaging programme to help ensure a successful outcome. Ultrasound, both grey-scale and colour-flow Doppler, are useful monitoring techniques when interpreted in the clinical context, and in the delineation of peri-transplant collections, some of which can be drained under ultrasound guidance. After the early post-operative period it can also be utilized in the diagnosis of chronic vascular complications including transplant artery stenosis and arteriovenous fistula, although it is of limited use in the diagnosis of chronic rejection. This article will discuss the role of ultrasound in all its guises and how its efficacy in both the early transplant period in the monitoring of graft dysfunction and in the detection of the more chronic conditions including transplant artery stenosis and arteriovenous fistulae. A more limited role for ultrasound also exists in the long-term follow-up of patients and to aid the detection of complications including susceptibility to malignancy. Baxter, G.M. (2001)

    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.

    One of the most significant advances in medicine during the last 50 years is the development of organ transplantation. In the context of chronic kidney diseases, renal transplantation offers patients a better clinical outcome than other treatment options. However, the benefits of organ transplantation have not been maximized due to an inadequate supply of organs for transplantation. Despite the establishment of elaborate legal rules for organs procurement, both on deceased and living donors in numerous countries, ethical concerns remain. Most of them are consequences of the strategies implemented or proposed to address the so-called organ shortage. The involvement of society in these complex problems is crucial as numerous questions emerge: could actual state of organ procurement change? Is it possible and/or realistic to increase the number of organs, with respects to living donors or deceased persons? Is the shortage an indicator to limit the use of kidney transplantation? How do we maintain efficiency and justice, in this context. PMID:23168353

    Renal transplantation (RTx) has become an accepted mode of therapy in infants with severe renal failure. The major indications are structural abnormalities of the urinary tract, congenital nephrotic syndrome, polycystic diseases, and neonatal kidney injury. Assessment of these infants needs expertise and time as well as active treatment before RTx to ensure optimal growth and development, and to avoid complications that could lead to permanent neurological defects. RTx can be performed already in infants weighing around 5 kg, but most operations occur in infants with a weight of 10 kg or more. Perioperative management focuses on adequate perfusion of the allograft and avoidance of thrombotic and other surgical complications. Important long-term issues include rejections, infections, graft function, growth, bone health, metabolic problems, neurocognitive development, adherence to medication, pubertal maturation, and quality of life. The overall outcome of infant RTx has dramatically improved, with long-term patient and graft survivals of over 90 and 80 %, respectively. PMID:26115617

  9. Protocol biopsies for renal transplantation

    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.

    2012-02-01

    There is a worldwide increase in the incidence of end-stage renal disease. Renal transplantation has been shown to be cost effective, prolong survival and provide a better quality of life in comparison to dialysis. Consequently, there has been a steady increase in demand for organs leading to a shortage of available kidneys, and an increase in transplant waiting lists. Renal transplantation is therefore an expanding field with a number of unique future challenges to address. This article outlines strategies that may be employed to expand organ supply in order to meet increased demand. The ethical issues surrounding this are also summarized. Furthermore, we highlight techniques with the potential to minimize peri-transplant injury to the kidney on its journey from donor to recipient. Current and potential future management strategies to optimize graft and patient survival are also discussed. PMID:22361673

    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.

    Central nervous system leiomyosarcomas are extremely rare, however, they became more frequent among immuno-deficient patients, either in a patients infected with human immunodeficiency virus (HIV), or after organ transplantation. The data of the literature indicate that the infection by Epstein-Barr virus (EBV) plays a causal role in the development of these tumours but its precise role in the onco-genesis remains unresolved. We report a new case of EBV associated leiomyosarcoma of the left cavernous sinus occurring after renal transplantation. The epidemiological, clinical, pathological and therapeutic characteristics of these tumours are discussed. (authors)

  15. Pulmonary complications in renal transplantation

    International Nuclear Information System (INIS)

    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

    Renal transplantation is the therapy of choice in patients with end stage renal disease. Although transplant rejection remains the most common complication after renal transplantation, vascular anatomical complications occur in 1%-23% of renal transplant recipients. Interventional radiologists play an important role in the management of these complications. This review discusses the role of image-guided interventions within the context of multidisciplinary patient management. Particular emphasis is given to anatomical considerations unique to this patient population, techniques used for image-guided interventions, and outcomes of image-guided interventions. PMID:27641457

  18. BELATACEPT IN RENAL TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    A. I. Sushkov

    2013-01-01

    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.

    1987-10-01

    Full Text Available Tuberculosis (TB was diagnosed in 25 of 466 patients who underwent renal transplant over a period of 15 years. TB developed from 1 month to 9 years post-transplant. In 56% of the cases the onset was within the first post-transplant year. TB affected several isolated or combined organs. Pulmonary involvement was present in 76% of cases, either as isolated pleuro-pulmonary (56% or associated with other sites (20%. The non-pulmonary sites were: skin, joints, tests, urinary tract, central nervous system and lymphonodules. The diagnosis was confirmed by biopsy in 64% of the cases, by identification of tubercle bacilli in 24% and only at necropsy in 12% Biopsy specimens could be classified in three histological forms: exudative, that occurred in early onset and more severe cases granulomatous in late onset and benign cases; and mixed in intermediate cases. Azathioprine dosages were similar along post-transplant time periods in TB patients and in the control groups; and in TB patients who were cured and who died. The number of steroid treated rejection crises was greater in TB than in the control group. Prednisone doses were higher and the number of rejection crises was greater in TB patients who died than in those who were cured. Fifteen patients were cured and ten died, two of them of causes unrelated to TB. Six of the eight TB-related deaths occurred in the first 6 post-transplant months. The outcome was poor in patients in whom TB arose early in post-transplant period and where the exudative or mixed forms were present; whereas the prognosis was good in patients with late onset and granulomatous form of TB. In one patient TB was transmitted by the allograft.

    Although mucocutaneous candidiasis is a common infection in renal transplant recipients, disseminated candidiasis is rare. Candida pnemonia causing miliary mottling on X-ray chest with the central nervous system involvement is still rarer. We report an unusual case with disseminated candidiasis that presented 18 years after renal transplantation and improved on conventional antifungal therapy; the relevant literature is reviewed.

  2. Risk factors of post renal transplant hyperparathyroidism

    International Nuclear Information System (INIS)

    It is well recognized that patients with end stage renal diseases (ESRD) have hyper-plastic parathyroid glands. In most patients, a decrease in parathyroid hormone (PTH) occurs by about 1 year after renal transplantation. However, some renal transplant recipients continue to have elevated level of PTH. We prospectively evaluated 121 patients undergoing renal transplantation between August 2000 and 2002. The duration of dialysis, calcium (Ca), phosphorus (P), albumin, creatinine and iPTH levels were recorded prior to transplantation and three months and one year after transplantation. These 121 patients were on dialysis for an average period of 17.4 months prior to transplantation. An increase in the serum Ca and a decrease in serum P and iPTH level was seen in the patients after transplantation (P< 0.001). Hyperparathyroidism was in 12 (9.9%) and 7 (5.7%) patients three months and one year after transplantation respectively. Elderly patients and patients with longer duration on dialysis had an increased risk of developing post transplant hyperparathyroidism and hypercalcemia in the first year post transplant (P< 0.05). In conclusion age and duration on dialysis before transplantation seems to be important risk factors for post transplant hyperparathyroidism. (author)

    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.

    2016-02-01

    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.

  7. The renal scan in pregnant renal transplant patients

    International Nuclear Information System (INIS)

    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 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.

    2002-07-01

    Colchicine is widely employed for the treatment of gout in renal transplant patients where NSAIDs are contra-indicated and allopurinol prophylaxis is often avoided due to concomitant azathioprine immunosuppression. We report here a case of colchicine-induced myoneuropathy in a renal transplant recipient. Our patient had myalgia, muscle weakness, elevated creatine kinase levels, myopathic changes on electromyography and peripheral neuropathy. Withdrawal of colchicine resulted in recovery within 4 weeks. Renal transplant recipients are likely to be at greater risk of colchicine-induced myoneuropathy due to the unique concurrence of risk factors predisposing to toxicity in such patients. These risk factors include the high incidence of gout in this population, widespread use of colchicine as first-line therapy, impaired renal function and concomitant cyclosporin treatment. The diagnosis should be considered in any renal transplant recipient receiving the drug who develops myopathy. Prompt withdrawal of colchicine therapy should result in rapid clinical and biochemical improvement. PMID:12122515

    The aim of the study reported here was to evaluate the contribution of renoscintigraphy performed frequently and systematically, for differentiation between the various complications occurring after renal transplantation. Relevant complications of renal transplantation are described, with special attention to the diagnostic methods available at present, and the methods used for radionuclide investigations in renal transplantation are reviewed. The abnormalities seen on the sequential images in ten cases complicated by urine leakage or urinary tract obstruction are described. These are illustrated by the scintigrams and the corresponding radiograms. The results in eight patients whose transplant did not show Hippuran uptake are also described. Transplant failure in five of these eight patients was clearly demonstrated by perfusion scintigraphy. (Auth.)

    Full Text Available Context: The magnitude 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. Aim: This study was conducted to determine the prevalence of intestinal parasitic infections in renal transplant recipients in Iran. Materials and Methods: Stool specimens from renal transplant recipients and control groups were obtained between June 2006 and January 2007. The samples were screened for intestinal parasitic infections using direct smear, formalin-ether sedimentation, Sheather′s flotation and modified Ziehl-Neelsen staining methods. Statistical Analysis Used: A comparison of the frequency of parasites between cases and controls was performed using Chi-square test. Subsequently, the Wilcoxon rank-sum test was used to compare multiple parasitic infections in cases and controls. P value <0.05 was considered significant. Results: Out of 150 renal transplant recipients, 33.3% (50, and out of 225 of the control group, 20% (45 were infected with one or more types 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. Conclusions: 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 severity of infection. The results of this study emphasize the monitoring and stool examination for prevention of parasitic infections in renal transplant recipients.

    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.

    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. PMID:7006837

    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

    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.

    This study demonstrates the normal technetium-99m diethylenetriaminepentaacetic acid ([/sup 99m/Tc]DTPA) renal scan in pregnant patients with transplanted kidneys. Five pregnant renal transplant patients had seven [/sup 99m/Tc]DTPA renal studies to assess allograft perfusion and function. All scans showed the uteroplacental complex. The bladder was always compressed and distorted. The transplanted kidney was frequently rotated to a more vertical position. In all patients allograft flow and function were maintained. There was calyceal retention on all studies and ureteral retention activity in three of five patients. Using the MIRD formalism, the total radiation absorbed dose to the fetus was calculated to be 271 mrad. This radiation exposure is well within NRCP limits for the fetus of radiation workers and an acceptable low risk in the management of these high risk obstetric patients

    2009-01-01

    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...

    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.

  2. Urolithiasis in renal transplantation: Diagnosis and management

    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.

    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.

    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 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

    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.

    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.

    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.

  15. Computerized technique for evaluating renal transplant function

    International Nuclear Information System (INIS)

    This investigation was undertaken to improve the assessment of renal transplant function in the early post-operative period when the usual measures of renal function afford little useful information. A simplified mathematical model of I-131 hippurate transport allows separation of renal uptake and excretion. Uptake (U) is defined as the fraction of I-131 hippurate in the plasma picked up by the kidney per minute, and excretion (E), the fraction of I-131 hippurate in the kidney excreted into the bladder per minute. Scintillation camera data from the region of the renal allograft are framed at 4/min by a computer system for up to 30 minutes post injection. After regions of interest are flagged over the kidney, bladder and background regions, the activity-time curves are analyzed, and values for U and E are output in a report updated through punched paper tape for any values from previous studies. The entire analysis of a patient study requires about 5 minutes of technologist time. Over 150 studies on 24 patients have been analyzed using the above technique. In the immediate post-operative state when anuria or severe oliguria is often present, sequential estimation of U was found to be a sensitive measure of renal transplant viability. In the period beyond one week reductions in U and E appeared to be sensitive measures of rejection, while increases in U and E heralded amelioration of the rejection episode. Changes in U and E appeared to be more sensitive measures of changes in renal function than routine qualitative scintiphotographic analysis. This technique has proven useful in following the renal function status of the kidney transplant recipient through acute tubular necrosis and rejection episodes and has been a significant adjunct to routine scintigraphy

    The aim of this study was to establish the prevalence of anemia in stable pediatric renal transplant recipients and to examine the association of anemia with renal function, immunosuppressants, angiotensin converting enzyme inhibitors, and growth, as well as iron, vitamin B(12), and folate stores. This is a cross-sectional study of the 50 renal transplant recipients currently followed at our center. Patient data were collected regarding hematological parameters, growth, medications, renal function, underlying renal disease, delayed graft function, episodes of rejection, and iron or erythropoietin therapy post transplantation. The mean hemoglobin level (Hb) was 110 g/l and the overall prevalence of anemia was 60%, including 30% who were severely anemic (Hb<100 g/l). There was a high rate of iron deficiency (34%) and serum iron was the parameter of iron metabolism most closely associated with anemia. Hb in patients with low serum iron was 90.7 g/l versus 114.4 g/l in those with normal serum iron ( P<0.01). Both univariate and multiple linear regression determined tacrolimus dose and creatinine clearance to be significant factors associated with anemia. Tacrolimus dose correlated with a 10 g/l reduction in Hb for every increase of tacrolimus dose of 0.054 mg/kg per day ( P=0.001). The dose of mycophenolate was positively correlated with Hb, but this was likely to be confounded by our practice of dose reduction in the setting of anemia. Angiotensin converting enzyme inhibitor use was not associated with anemia. Severely anemic patients tended to be shorter, with a mean Z-score for height of -1.8 compared with -0.9 for those with normal Hb ( P=0.02). Anemia is a significant and common problem in pediatric renal transplant patients. Deteriorating renal function is an important cause, but other factors like iron deficiency and immunosuppression are involved. Definition of iron deficiency is difficult and serum iron may be a valuable indicator. Medication doses

    Fertility in women with kidney failure is restored by transplantation. It requires careful planning and is only advisable in women with good kidney function, controlled blood pressure, and general good health. Immunosuppressive drugs carry risks for the fetus, but the risks of prednisone, azathioprine, cyclosporine, and tacrolimus are surprisingly low. Mycophenolate is teratogenic. The success rate for pregnancy in kidney transplant recipients is lower than in the general population with 70% to 80% of pregnancies resulting in surviving infants. Prematurity, intrauterine growth restriction, and preeclampsia are all increased. Complications are higher and outcomes are worse for women with serum creatinine levels over 1.3 mg/dL. Ten to 15% of women have a temporary or permanent decline in kidney function, particularly if prepregnancy creatinine is high. Transplant-related infections can be serious for the mother and fetus. A multidisciplinary team should coordinate care. PMID:23928390

    Full Text Available Clinical case of prolonged massive polyuria in patient after renal transplantation is represented in this article. Polyuria lasted for a forty days after kidney transplantation, the larges amount of urine output was 55 litres per day. Analysis of transplant biopsy revealed acute tubular necrosis, initial arteriolosclerosis and suspected acute rejection. Doppler ultrasound study and perfusion scintigraphy detected no pathology. At first we tried to decrease the volume of infusion and fluid intake. Also we performed pulse therapy with methylprednisolone. However, these efforts were not effective. Using of a large doses of «Minerin» (posterior pituitary antidiuretic factor allowed to decrease and stabilize the volume of urine output. The patient was discharge from clinic on day 42 after transplantation

    Background Filamentous fungal infections are associated with a high morbidity and mortality in solid organ transplants.The present study aimed to investigate the aspergillus pneumonia in renal transplant recipients, and its diagnosis as well as treatment.Methods Approximately 2000 cases of renal transplants were retrospectively studied and we focused on cases hospitalized during August 1, 2005 and February 1, 2007, as the study period. The clinical database and electronic records were analyzed. Recently published literature was reviewed.Results There was more diabetes and hypertension in the infected group than in the non-infected group (86% vs 62% and 57% vs 39%, respectively). Eighty-six percent of recipients from the infected group had delayed graft function. Seven cases with aspergillus pneumonia were identified based on either fungal culture or radiology. Of the 7 cases, 4 died in a few days after diagnosis. Liposomal amphotericin B was used as a first-line therapy.Conclusions Incidences of fungal infection are increasing among renal transplant recipients. Early diagnosis and treatment are critical steps in curing aspergillosis.

    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.

    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.

    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.

    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.

    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.

  5. Renal Transplantation from Elderly Living Donors

    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.

    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.

    Full Text Available In this study, we aimed to evaluate the incidence, features and outcome of post trans-plant KS among Iranian recipients of living kidney allograft. We studied 2211 kidney allograft reci-pients who underwent living renal transplantation at our center between January 1984 and August 2007. All patients in our study received cyclosporine based immunosuppressive agents. The diagno-sis of KS was confirmed with pathological evaluations of tissue biopsy specimens. There were 10 of 2211 (0.45% incident cases of KS kidney transplant population at our center during a mean follow up of 57 ± 38 months. Of the 10 KS patients, 8 were males and two were females with a median age of 52 years. The median time from transplantation to the development of KS was 8 months. Overall, two (20% patients developed visceral involvement (one eye, one bladder, and eight patients mani-fested only KS restricted to the skin. Immunosuppression was reduced in 5 patients and thoroughly withdrawn in the remainder (including two cases of visceral involvement; KS did not abate in the patient with bladder involvement. All the KS patients remained alive after a mean of 35.6 ± 39.3 months of follow up; two patients lost their allograft and underwent dialysis (one after 3 months and one another after 4 months of KS diagnosis. The KS patients were significantly older at their transplantation time (P= 0.008; [Table 1]. Survival analysis using Kaplan Meier method and log-rank test revealed no difference in graft and patient survival between both groups. In conclusion, we found low incidence of KS in our living renal transplant recipients. The outcome of the KS patients was excellent with low morbidity and mortality. The incidence of KS was significantly associated with an older age at transplantation time for the allograft recipients. Further studies with larger pa-tient population are warranted to confirm our results.

    The purpose of this study was to evaluate the prevalence of symptomatic parasitic infections in adult renal transplant recipients. We retrospectively analyzed a sample of 657 adult renal transplant recipients performed from January 2001 to December 2005 for immunosuppression protocol, clinical manifestations, parasite diagnosis, treatments, and outcomes. The prevalence of symptomatic parasitosis infections was 2.4% (16/657). None of the infected patients received cyclosporine in their immunosuppression protocol. Most of the infections were caused by Strongyloids stercoralis (n = 11), followed by Giardia lamblia (n = 3), Toxoplasma gondii (n = 1), and Trypanosoma cruzi: (n = 1). Strongyloides stercoralis was the most frequent agent, causing three cases of hyperinfection including one fatal case. With the new immunosuppressive regimes there must be a suspicion of parasitic infection to avoid the diagnostic delay that can be fatal. Strategies, including empiric treatment for S. stercoralis, must be considered. PMID:17362759

    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.

    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.

    2010-05-01

    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. PMID:20586909

    Patients with end-stage renal disease who receive a kidney through transplantation enter a new phase in their illness trajectory. The question emerged which knowledge and skills are essential for a safe self-management immediately after the transplantation. The aim of this project was to develop an evidence-based in-patient education programme for renal transplant recipients. A participative action research approach was chosen. An interprofessional group, led by an advanced practice nurse, initiated the project. Based on a systematic literature review and on qualitative interviews with both patients and experts, an in-patient educational programme was developed and implemented. The main elements of the programme focused on taking medications appropriately and on the observation and interpretation of symptoms. The content of the programme was documented in a brochure for patients. The structure of the programme was documented in a guideline with a standardised procedure. The procedure was based on patients' needs and preferences, and therefore provides tailored education. Besides the support received in gaining relevant knowledge, patients are supported in developing practical skills, problem solving, and decision making. An initial evaluation revealed that patients with cognitive impairment have special needs for education that exceeds what exists in the developed programme. As the programme is revised, additional contents on psychosocial issues will be included and the programme will be planned along the clinical pathway. Furthermore, it should begin during the pre-transplant period and continue in a longterm follow-up. PMID:21964935

    1978-06-01

    Fourteen patients (13 of them adolescents) interrupted immunosuppressive treatment following renal transplantation. Twelve were girls and two were boys. Six subsequently lost their allografts and eight had impaired renal function. Noncompliance was suspected when diminution in cushingoid features, unexplained weight loss, or changes in renal function occurred. Noncompliance was comfirmed by interview with psychosocial staff. Available psychosocial data from family interview and personality test obtained earlier as part of systematic follow-up study were analyzed to explore the reasons for noncompliance. Non compliant patient families had lower incomes, more fatherless households, and comunication difficulties within the family and with the medical establishment. Using a stepwise discriminant analysis, a discriminant function was derived which selected 13 of 14 noncompliant patients. Noncompliance may be a preventable cause of allograft failure. These data can aid in identifying high-risk patients and planning intervention programs. PMID:353683

We report a six-years (December 1991 to December 1996 follow-up of 60 LURT patients. The majority of these patients (95% were transplanted outside the Kingdom of Saudi Arabia; 37 in India, 14 in Egypt, five in the USA and one in Pakistan. Only three patients (emotionally related were transplanted in Saudi Arabia. Before transplantation, 50 (83.4% patients were on chronic hemodialysis, three (5% on peritoneal dialysis and three (5% were transplanted pre-emptively. Post-operatively, the majority of the study patients were on three drug immunosuppressive therapy. One and five year graft survival was 93.0% and 59.6%, while patient survival at one and three years was 93.7% and 81%, respectively. Surgical complications included lymphocele in 10% of the study patients, urinary leak in 8.3%, and bleeding from the vascular anastomosis in 6.6%. There were eight episodes of acute rejection in eight (13.3% patients and all episodes were successfully treated; two patients required monoclonal anti-lymphocyte antibodies (OKT3. Eleven (18.3% patients developed chronic rejection, which resulted in the loss of ten (90% allografts. Infection was the commonest cause for hospital admission; urinary tract infection (UTI being responsible for 40% of admissions. Three patients had Cytomegalovirus pneumonia, one had Pneumocystis Carinii pneumonia and one had candida pneumonia. Two (3% patients developed Kaposi′s sarcoma. We conclude that LURT can help in overcoming the shortage of organs for transplant, however, commercial transplantion in developing countries is associated with high morbidity and mortality.

    In the last two decades, perceptions about the role of body fat have changed. Adipocytes modulate endocrine and immune homeostasis by synthesizing hundreds of hormones, known as adipocytokines. Many studies have been investigating the influences and effects of these adipocytokines and suggest that they are modulated by the nutritional and immunologic milieu. Kidney transplant recipients (KTRs) are a unique and relevant population in which the function of adipocytokines can be examined, given their altered nutritional and immune status and subsequent dysregulation of adipocytokine metabolism. In this review, we summarize the recent findings about four specific adipocytokines and their respective roles in KTRs. We decided to evaluate the most widely described adipocytokines, including leptin, adiponectin, visfatin and resistin. Increasing evidence suggests that these adipocytokines may lead to cardiovascular events and metabolic changes in the general population and may also increase mortality and graft loss rate in KTRs. In addition, we present findings on the interrelationship between serum adipocytokine levels and nutritional and immunologic status, and mechanisms by which adipocytokines modulate morbidity and outcomes in KTRs.

    2011-01-01

    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.

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'. PMID:22673884

    Short-term outcomes in renal transplantation have improved significantly in the past few years. However, the improvement in long-term outcomes has been modest. The reasons for graft failure beyond the first year of transplantation have been attributed to several different factors. We believe that subclinical rejection (SCR) may be 1 of the factors that contribute to graft loss in the long run. We also believe that there are data to suggest that SCR leads to progressive fibrosis and loss of graft function. This has been demonstrated even in patients who have mild degrees of subclinical inflammation. This review outlines the major studies that have been published on this important topic. It also outlines potential risk factors for the development of SCR. The current approach and diagnostic methods are discussed as well as their pros and cons. Newer noninvasive methods of diagnosis as well as molecular diagnostics and their merits and shortcomings are also discussed in some depth. Thus, the proposed state of the art review on SCR will create a renewed interest at all levels including transplant clinicians, transplant researchers, pharmaceutical industries as well as regulatory organizations.

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

    Alternariosis is a fungal infection that is usually described in immunocompromised patients. We report a case of cutaneous alternariosis in a renal transplant recipient caused by Alternaria tenuissima. The diagnosis was supported by histopathologic (ie, yeastlike cells, filamentous structures) and mycologic findings from a cutaneous biopsy. Cutaneous lesions regressed 1 month following a decrease in the dosage of immunosuppressive therapy. The patient also was treated with intravenous amphotericin B followed by oral fluconazole without improvement. Cryotherapy remarkably accelerated healing of the lesions. PMID:24897135

    Clinical gout has rarely been described after pediatric renal transplantation (RTx), although asymptomatic hyperuricemia is common in these patients. We describe three male pediatric patients who presented with gouty arthritis 7-8.5 years following RTx. Since receiving allopurinol, all patients had been free of gouty symptoms. To prevent severe bone marrow depletion, the dosage of azathioprine, an immunosupressant drug, was reduced by 50% to prevent interaction with allopurinol. Because atypical presentation of gout can occur, a high index of suspicion is needed to allow appropriate diagnosis of this disease in patients with skeletal pain after RTx. PMID:20640905

    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.

    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.

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

    2012-01-01

    In renal transplantation, immunosuppressants are prescribed to patients to prevent graft loss. Although the extent of adherence required for such treatment to prevent graft loss has not been determined, it is thought to be high. Despite this, research suggests adherence rates for renal transplant recipients to be only between 50% and 95%. Considering the impact of graft loss on the renal patient, the national healthcare budget and on the limited resource of donor organs, it is important to id...

    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.

    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.

    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. PMID:27018408

    Renal lymphangiomatosis is a disease characterized by abnormal formation of perirenal lymphatic vessels that fail to communicate with other retroperitoneal lymphatics; as a result, perirenal lymphatics dilate and form cysts. While typically an asymptomatic incidental finding, renal lymphangiomatosis rarely presents as flank or abdominal pain, ascites, impaired renal function, hypertension, hematuria, or proteinuria. Here we present the first known case of renal lymphangiomatosis found to spontaneously resolve following cardiac transplantation.

    Strongyloidiasis is infection caused by the nematode Strongyloides stercoralis. Chronic uncomplicated strongyloidiasis is known to occur in immunocompetent individuals while hyperinfection and dissemination occurs in selective immunosuppressed hosts particularly those on corticosteroid therapy. We report two cases of hyperinfection strongyloidiasis in renal transplant recipients and document endoscopic and pathological changes in the involved small bowel. One patient presented with features of dehydration and malnutrition while another developed ileal obstruction and strangulation, requiring bowel resection. Oesophagogastroduodenoscopy showed erythematous and thickened duodenal mucosal folds. Histopathological examination of duodenal biopsies revealed S. stercoralis worms, larvae and eggs embedded in mucosa and submucosa. Wet mount stool preparation showed filariform larvae of S. stercoralis in both cases. Patients were managed with anthelmintic therapy (ivermectin/albendazole) and concurrent reduction of immunosuppression. Both patients had uneventful recovery. Complicated strongyloidiasis should be suspected in immunocompromised hosts who present with abdominal pain, vomiting and diarrhoea, particularly in endemic areas. PMID:25150235

    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.

    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

    While most BK virus infections are asymptomatic, immunosuppression has been associated with BK virus reactivation and impaired graft function or ureteric ulceration in renal transplant patients and hemorrhagic cystitis in bone marrow transplant patients. Oncogenicity is also postulated and this is the first report of a child with a carcinoma of the donor renal pelvis following BK virus allograft nephropathy.

    Full Text Available We undertook this observational study to assess the incidence of acute rejections (AR in the first six months after transplantation at Al-Karama Hospital, Iraq. Sixty eight patients (49 males and 19 females underwent renal transplantation in 2006 and were followed up weekly. Forty six received kidneys from related donors and 22 from unrelated donors. During the first six months after transplantation AR occurred in 16 patients (23%; 11 (23% related and 5 (23% unrelated donor transplantation. We conclude that the incidence of acute rejection was similar in related and unrelated donor transplantation and the general incidence was comparable to that reported from most centers.

    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.

The majority of candidates for kidney transplantation have arteriosclerosis to some extent; thus, preoperative imaging of the vessels is needed. Different imaging modalities are available and are used...... renal transplantation. In 2006, it was realised that the Gd used in CEMRA could cause NSF, which prompted the Danish National Board of Health to produce guidelines for the use of contrast agents in patients with severe renal disease. This thesis discusses different preoperative imaging methods without...... contrast agents before kidney transplantation and kidney donation. Study I is a review of NCMRA techniques and clinical applications. In study II, we searched for an NCMRA method with consistently good image quality for the examination of the pelvic vessels in patients with severe renal disease. Five...

    A 59-year-old woman with end-stage renal disease of diabetic nephropathy who had been on maintenance hemodialisis for 4 years, underwent a living-unrelated renal transplantation 6 years ago. She was admitted to our hospital, because of a low grade fever and edema. Ultrasonography revealed the cyst with heterogeneity structure in the upper pole of the transplanted kidney. Magnetic resonance imaging showed a high-intensity cystic mass measuring 68×53 mm. As fever and laboratory data did not improve sufficiently by the treatment with antibiotics, echo-guided puncture and drainage were performed for the abnormal structure in the upper pole of the transplanted kidney. In the culture of the purulent aspirate drained from renal cyst, Escherichia coli was isolated. To our knowledge, this is the first report of infected renal cyst of the graft in a renal transplant recipient in the world. PMID:22075611

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

    International Nuclear Information System (INIS)

    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

    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.

  3. Intractable urinary tract infection in a renal transplant recipient

    International Nuclear Information System (INIS)

    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 allograft recipient who presented with relapsing bacterial UTI complicated by systemic fungemia; also, a brief review of fungal UTI is attempted. (author)

    Full Text Available Amoebic liver abscess (ALA is by far the most common extraintestinal manifestation of invasive amoebiasis. The vast majority of these resolve with treatment; however, a small percentage of the treated ALAs are known to persist asymptomatically. Herein, we present a prospective renal allograft recipient with a residual liver abscess who had a successful renal transplant after treatment. In our opinion, persistence of a radiological finding of residual abscess in the absence of clinical disease does not appear to be a contraindication to renal transplantation.

    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.

    Phelan, P J

    2012-02-01

    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.

    Organ transplantation has always been considered to be the standard therapeutic interventions in patients with end-stage organ failure. In 2008, more than 29,000 organ transplants were performed in US. Survival rates among transplant recipients have greatly improved due to better understanding of transplant biology and more effective immunosuppressive agents. After transplant, the extent of the immune response is influenced by the amount of interleukin 2 (IL-2) being produced by the T-helper ...

  8. Implications of the Kidd blood group system in renal transplantation.

    Rourk, A; Squires, J E

    2012-01-01

    The association of the Kidd blood group system with hemolytic transfusion reactions and hemolytic disease of the newborn is well known. The Kidd antigens, which are localized to the HUT/UT-B urea transport protein, are found on red blood cells and the endothelial cells of the blood vessels of the medulla of the kidney. Recently it has been suggested that these antigens might play a role as minor histocompatibility antigens in renal transplantation. In the current case, the appearance of an anti-Jk(b) 10 years after renal transplantation associated with early renal allograft rejection further supports the potential importance of these antigens in renal transplantation and allograft rejection.

    Population of patients with end-stage renal disease increases every day. There is a vast difference in the number of patients on the waiting list for a kidney transplant, and the number of donors and the gap increases every year. The use of more marginal organs can increase the donor pool. These organs include the kidneys with small renal cell carcinomas (RCTC). There has been a number of reports in the literature about the use of these grafts for renal transplant after tumor excision and reconstruction. These grafts have been reported to be used with good renal function outcomes without an increased risk for malignancy recurrences. We present the collection of evidence for the use of kidneys with RCC for transplantation, technique used for surgical resection, and reconstruction as well as insights on the recommendations for the use of these grafts.

    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.

    2016-03-01

    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 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 <6 weeks on dialysis is the best therapeutic option for end-stage renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

    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.

    2014-01-01

    Full Text Available 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.

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

    2008-01-01

    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.

    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.

    Full Text Available Abstract Background There is a relative lack of recent information about late post kidney transplantation anaemia (PTA, especially in the developing countries; data are scarce about the prevalence and risk factors of PTA. Sudan was a leading country in Africa and Arab world in kidney transplantation. The first kidney transplantation in Sudan was in 1973. Methods This is a cross-sectional hospital analytic study enrolling all kidney transplanted recipients following in the transplant referral clinics at Ahmed Gassim, Selma and Ibn Sina Hospitals, Khartoum/Sudan, in the period from 1/8/2010 to 1/9/2010, clinical and laboratory data were obtained from 114 patients, anaemia was defined as Hb levels of Results The study showed that 39.5% of the patients were anaemic. Univariate analysis showed that late PTA is significantly associated with not using Erythropoietin (EPO in the pre-transplant period (p = Conclusion The study concluded that late PTA is common and under recognized. Risk factors for late PTA include renal dysfunction, history of rejection, longer duration of transplantation and not using EPO in the pre-transplant period. Renal dysfunction and not using EPO in the pre-transplant period are major predictors of late PTA.

    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.

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.

    18 renal transplant recipients receiving cyclosporin, prednisone, and azathioprine were given ketoconazole, a potent inhibitor of the cytochrome P-450 enzyme system. Within a month ketoconazole-induced blockade of cyclosporin metabolism allowed a significant reduction (451 vs 106 mg/day; 77%) of the mean dose of cyclosporin without altering cyclosporin whole blood trough levels, although maximum blood levels were almost halved. This dose reduction was maintained in patients followed up for up to 13 months. Renal and hepatic function were unchanged after the addition of ketoconazole. This drug interaction has the potential to reduce dramatically expenditure on cyclosporin in transplant recipients. PMID:2572912

    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.

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.

    Full Text Available Mucormycosis is a rarely encountered invasive fungal infection with high mortality.Solid organ transplantation is one of the risk factors for mucormycosis. Mucormycosis can be classified in six different groups according to the anatomical localization; rhinocerebral, pulmonary, cutaneous, gastrointestinal, disseminated, and other less common involvements. This paper presented a mucormycosis case with rhinoorbitocerebral involvementin a renal transplantation receiver, which manifested with orbital apex syndrome. [Cukurova Med J 2015; 40(2.000: 384-389

    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.

    Full Text Available This study was undertaken to study the changes in neuropathy in type 1 diabetic patients with end-stage renal disease (ESRD after renal transplantation. From April 2007 to June 2010, 30 renal transplanted patients with type 1 diabetes mellitus (RT and 30 type 1 diabetic patients with ESRD were enrolled in this study. Electroneurodiagnostic tests of peroneal, sural, ulnar, and median nerves were performed. Nerve conduction velocity (NCV, compound motor action potentials (CMAPs, and sensory nerve action potentials (SNAPs were analyzed at 6, 12, and 18 months after renal transplantation. The NCV improved in the RT group in 18 months of the follow-up period (P <0.01 versus baseline. This parameter worsened significantly in the control group throughout the study period (P = 0.03, but in the cross-sectional analysis between the groups, we could not find any remarkable differences (P = 0.07. Both SNAP and CMAP amplitudes improved in the RT (SNAP Sural = 0.04, SNAP Median = 0.01 and CAMP Peroneal = 0.03, CAMP Ulnar = 0.02 but worsened in the control group (SNAP Sural < 0.001, SAP Median < 0.01 and CAMP Peroneal < 0.01, CAMP Ulnar < 0.01. Comparison of both groups did not show any significant statistical changes. Electroneurodiagnostic values improved after renal transplantation in type 1 diabetic patients with ESRD, but cross-sectional analysis did not reveal statistically significant differences between the studied groups.

    2009-01-01

    Renal transplantation from a living donor shows a better graft and patient survival when compared with cadaver donor grafts. Moreover, since surgery can be planned in advance when a living donor is available, the time spent on dialysis while awaiting transplantation can be greatly reduced and dialysis treatment can be completely avoided in some cases. Only few risks for the donor have been reported as a consequence of nephrectomy, both in the short and long term. Nevertheless, despite these advantages, the number of living donor renal transplants carried out in Europe each year varies greatly from country to country and is particularly low in Spain and Italy. Several factors account for these differences, mainly the effectiveness of the organ procurement system, which could make people reluctant to living donation, and doctors' and patients' limited knowledge about living donor transplants. Nephrologists have the responsibility to identify patients eligible for transplant early in the course of the disease, and to inform them and their relatives about living donor transplantation, enabling them to make informed choices among the various treatment options in end-stage renal disease.

    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.

    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?

    The differential diagnoses of a cavitary lung lesion in renal transplant recipients would include infection, malignancy and less commonly inflammatory diseases. Bacterial infection, Tuberculosis, Nocardiosis, fungal infections like Aspergillosis and Cryptococcosis need to be considered in these patients. Pulmonary cryptococcosis usually presents 16-21 mo after transplantation, more frequently in patients who have a high level of cumulative immunosuppression. Here we discuss an interesting patient who never received any induction/anti-rejection therapy but developed both BK virus nephropathy as well as severe pulmonary Cryptococcal infection after remaining stable for 6 years after transplantation. This case highlights the risk of serious opportunistic infections even in apparently low immunologic risk transplant recipients many years after transplantation. PMID:27358792

  19. Renal Vein Reconstruction for Harvesting Injury in Kidney Transplantation

    Directory of Open Access Journals (Sweden)

    Birkan Bozkurt

    2014-03-01

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

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

    Ischemic colitis is a well-recognized complication occurring in renal transplant recipients. It has often been associated with cytomegalovirus (CMV) vasculitis. However, the diagnosis of this pathology in the absence of CMV suggests that other etiological factors might be involved. Drugs inducing mesenteric vasoconstriction, such as non-steroidal anti-inflamatory drugs (NSAIDs) and cyclosporine could be related to this entity.

    The goal of renal transplantation is to achieve the best possible quality of life in patients with terminal renal failure. To evaluate some aspects of quality of life in patients with renal grafts during childhood of our center, data on medical, educational and professional rehabilitation were collected retrospectively. Between 1972 and 1997 135 renal transplantations had been performed in 123 patients below the age of 18 years. 12-year graft survival of patients transplanted before 1983 figured at 21% and rose to 62% during the following years, after introduction of cyclosporine A into the immunosuppressive regimen. The proportion of patients in the respective age group attending a secondary school (16%) was lower and of those attending elementary school (71%) or a school for disabled and handicapped children (11%) was higher than usual in the German population. But, 83% of all patients reached a school degree. After school 78% proceeded with a vocational training or university. 89% of patients completing professional training were employed at last observation as compared to only 60% of those who never finished a professional training. Renal replacement therapy starting already during the early phase of education is difficult to coordinate with normal schooling. Considering these health- and time-related obstacles, the degree of educational and professional rehabilitation of the patients is good. But, there is a need for special support accompanying educational and professional training. PMID:10209838

    Full Text Available Bartter syndrome (BS is a clinically and genetically heterogeneous inherited renal tube disorder characterized by renal salt wasting, hypokalemic metabolic alkalosis and normotensive hyperreninemic hyperaldosteronism. There have been several case reports of BS complicated by focal segmental glomerulosclerosis (FSGS. Here, we have reported the case of a BS patient who developed FSGS and subsequent end-stage renal disease (ESRD and provided a brief literature review. The patient presented with classic BS at 3 months of age and developed proteinuria at 7 years. Renal biopsy performed at 11 years of age revealed a FSGS perihilar variant. Hemodialysis was initiated at 11 years of age, and kidney transplantation was performed at 16 years of age. The post-transplantation course has been uneventful for more than 3 years with complete disappearance of BS without the recurrence of FSGS. Genetic study revealed a homozygous p.Trp(TGG610Stop(TGA mutation in the CLCNKB gene. In summary, BS may be complicated by secondary FSGS due to the adaptive response to chronic salt-losing nephropathy, and FSGS may progress to ESRD in some patients. Renal transplantation in patients with BS and ESRD results in complete remission of BS.

  12. Detection of acute renal allograft rejection by analysis of Renal TissueProteomics in rat models of renal transplantation

    International Nuclear Information System (INIS)

    At present, the diagnosis of renal allograft rejection requires a renalbiopsy. Clinical management of renal transplant patients would be improved ifrapid, noninvasive and reliable biomarkers of rejection were available. Thisstudy is designed to determine whether such protein biomarkers can be foundin renal graft tissue proteomic approach. Orthotopic kidney transplantationswere performed using Fisher (F344) or Lewis rats as donors and Lewis rats asrecipients. Hence, there were two groups of renal transplant models: one isallograft (from F344 to Lewis rats); another is syngrafts (from Lewis toLewis rats) serving as control. Renal tissues were collected 3, 7 and 14 daysafter transplantation. As many 18 samples were analyzed by 2-DElectrophoresis and mass spectrometry (MALDI-TOF-TOF-MS). Elevendifferentially expressed proteins were identified between groups. Inconclusion, proteomic technology can detect renal tissue proteins associatedwith acute renal allograft rejection. Identification of these proteins asdiagnostic markers for rejection in patient's urine or sera may be useful andnon-invasive, and these proteins might serve as novel therapeutic targetsthat also help to improve the understanding of mechanisms of renal rejection.(author)

    Full Text Available A 45-year-old man with reactivation of previously existing and subsiding cutaneous leishmaniasis on his wrist and lower leg (shin after renal transplantation was admitted to our dermatology service on March 2008. He presented to us with two huge tumoral and cauliflower-like lesions. Skin smear and histopathology of skin showed leishman bodies and confirmed the diagnosis. After renal transplantation, he received cyclosporine plus prednisolone to induce immunosuppression and reduce the probability of transplant rejection. After immunosuppressive therapy, reactivation of cutaneous leishmaniasis with the above presentation took place. The patient responded to 800 mg/day intravenous sodium stibogluconate for 3 weeks plus local cryotherapy. Systemic plus local therapy along with reducing the doses of immunosuppressive drugs led to improvement of lesions. Reactivation of leishmaniasis after immunosuppression has been rarely reported.

    1983-05-01

    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.

    Full Text Available Context: Ureteral obstruction, resulting in impaired graft function, is a well-known problem following renal transplantation. Management of ureteral complications includes percutaneous nephrostomy, which is considered to be a safe and effective measure. Case Report: Here, we demonstrate a case of a 35-year old renal allograft recipient with primary graft function but stagnating serum creatinine following extraction of the double-J catheter. Ureteral stenosis was suspected by ultrasound imaging and magnetic resonance tomography, and urinary flow was preserved with a percutaneous nephrostomy. However, early displacement of the percutaneous nephrostomy catheter resulted in distinct clinical discomfort. CT imaging suggested an intra-abdominal position of the catheter’s tip, requiring immediate surgical action. Conclusion: The present case demonstrates that performing PCN following renal transplantation may have unexpected risks.

    '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.

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

  19. Viral Infection in Renal Transplant Recipients

    Directory of Open Access Journals (Sweden)

    Jovana Cukuranovic

    2012-01-01

    Full Text Available Viruses are among the most common causes of opportunistic infection after transplantation. The risk for viral infection is a function of the specific virus encountered, the intensity of immune suppression used to prevent graft rejection, and other host factors governing susceptibility. Although cytomegalovirus is the most common opportunistic pathogen seen in transplant recipients, numerous other viruses have also affected outcomes. In some cases, preventive measures such as pretransplant screening, prophylactic antiviral therapy, or posttransplant viral monitoring may limit the impact of these infections. Recent advances in laboratory monitoring and antiviral therapy have improved outcomes. Studies of viral latency, reactivation, and the cellular effects of viral infection will provide clues for future strategies in prevention and treatment of viral infections. This paper will summarize the major viral infections seen following transplant and discuss strategies for prevention and management of these potential pathogens.

    Full Text Available The frequency of infection by Cryptosporidium parvum was determined in two groups of renal patients submitted to immunosuppression. One group consisted of 23 renal transplanted individuals, and the other consisted of 32 patients with chronic renal insufficiency, periodically submitted to hemodialysis. A third group of 27 patients with systemic arterial hypertension, not immunosuppressed, was used as control. During a period of 18 months all the patients were submitted to faecal examination to detect C. parvum oocysts, for a total of 1 to 6 tests per patient. The results showed frequencies of C. parvum infection of 34.8%, 25% and 17.4%, respectively, for the renal transplanted group, the patients submitted to hemodialysis and the control group. Statistical analysis showed no significant differences among the three groups even though the frequency of C. parvum infection was higher in the transplanted group. However, when the number of fecal samples containing C. parvum oocysts was taken in account, a significantly higher frequency was found in the renal transplanted group.

    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.

    Phelan, P J

    2010-10-29

    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.

    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

    The aim of our study was to evaluate the occurrence of middle and long-term chronic renal failure (CRF) after orthotopic liver transplantation (OLT) in relation to acute renal failure (ARF). We prospectively monitored 75 patients, studying renal function on the basis of serum creatinine and glomerular filtration rate as estimated using the Modification of Diet in Renal Disease formula before as well as 1,6, and 12 months after OLT. The prevalence of ARF was 56% classified by the Acute Kidney injury Network criteria (52% stage 1, 29% stage 2, and 19% stage 3). The occurrences of CRF were 18.6% (11/59), 11.5% (6/52), and 14% (6/43) at 1, 6, and 12 months after OLT, respectively. The occurrence of CRF before OLT was 14.7%. We did not find any association between ARF and post-OLT CRF. The most relevant result of our study was the association between CRF at 6 and 12 months after transplantation with pre-OLT CRF on univariate and multivariate analysis. We suggest that evaluation of pre-OLT renal function should always be considered in the follow-up of liver transplant patients. Pre-OLT renal dysfunction must be recognized to be a risk factor for post-OLT CRF, representing important criterion to define specific therapeutic interventions to reduce patient morbidity and mortality.

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

    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.

    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.

    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.

    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. PMID:27105603

    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.

    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.

    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.

    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 Pulmonary nodules are common following solid organ transplantation and vary in etiology. Nodules with central cavitation are most likely to be of infectious origin in the post-transplant population. A novel presentation of post-transplant lymphoproliferative disorder manifesting as multiple cavitating pulmonary nodules is described. The patient, a 45-year-old female renal transplant recipient, presented with constitutional symptoms and a chest x-ray showing multiple bilateral cavitating lesions. A computed tomography scan confirmed innumerable, randomly dispersed, cavitating nodules in the lung parenchyma. Multiple large hypodense lesions were identified in the liver and spleen. The appearance of the native and transplanted kidneys was normal. A liver biopsy identified an Epstein-Barr virus-negative, diffuse, large B cell lymphoma. Repeat imaging after treatment with a cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone/prednisolone regimen demonstrated dramatic resolution of all lesions. The present case represents a unique radiographic presentation of post-transplant lymphoproliferative disorder not previously reported in the literature.

    Abstract Risk for atypical hemolytic uremic syndrome (aHUS) recurrence after renal transplantation is low with an isolated membrane cofactor protein mutation (MCP). We report the case of a 32-year-old woman with a MCP who underwent kidney transplantation with a good evolution at 12 months. At 15 and 35 months, 2 episodes of thrombotic microangiopathy (TMA), after a miscarriage and a preeclampsia, were misinterpreted as triggered by tacrolimus. After each episode however serum creatinine returned to baseline. Five years after transplantation, she had a self-limited rhinosinusitis followed 3 weeks later by an oliguric renal failure. Her complement profile was normal. Graft biopsy showed C3 glomerulonephritis with no “humps” on electron microscopy. No significant renal function improvement followed methylprednisolone pulsing. A second biopsy showed severe acute TMA lesions with C3 glomerular deposits. Despite weekly eculizumab for 1 month, dialysis was resumed. A new workup identified the “at-risk” complement factor H haplotype. Thus, aHUS recurrence should be ruled out in aHUS patients considered at low recurrence risk when a TMA is found in graft biopsy. Prompt eculizumab therapy should be considered to avoid graft loss as aHUS recurrence can first present as a C3 glomerulonephritis. PMID:27500215

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.

    Full Text Available Background/Aims: To assess the relationship between bone and vascular disease and its changes over time after renal transplantation. Metabolic bone disease (MBD is common in chronic kidney disease (CKD and is associated with cardiovascular (CV disease. Following transplantation (Tx, improvement in CV disease has been reported; however, data regarding changes in bone disease remain controversial. Methods: Bone turnover and arterial stiffness (pulse wave velocity (PWV were assessed in 47 Tx patients (38 (3-191 months after Tx. Results: Bone alkaline phosphatase (BALP, osteocalcin (OC and beta-crosslaps were significantly higher in Tx patients, and decreased significantly after one year. There was a negative correlation between BALP, OC and steroid administered (r=-0.35;r=-0.36 respectively. PWV increased in the Tx group (1.15 SD. In patients with a follow up of Conclusions: Increased bone turnover and arterial stiffness are present following kidney transplantation. While bone turnover decreases with time, arterial stiffness correlates initially with bone turnover, after which the influence of cholesterol becomes significant. Non-invasive estimation of bone metabolism and arterial stiffness may help to assess CKD-MBD following renal transplantation.

    Renal artery anastomotic pseudoaneurysms, an uncommon complication of transplantation, may result in aneurysm rupture and loss of allograft. We report the case of 50-year-old female with back pain 3 weeks post renal transplantation. CT scan revealed transplant renal artery anastomotic pseudoaneurysm arising from anastomosis of two renal arteries joined together to form a single renal artery that was joined to the aorta. Successful endovascular treatment was achieved with covered stents, resulting in preserved renal function. Follow-up ultrasound at one-day post procedure and CT at 2 months revealed satisfactory renal perfusion with no pseudoaneurysm. Endovascular treatment of transplant renal artery pseudoaneurysms with covered stent and ostial flare balloon technology may be preferred in patients with extensive prior pelvic surgery, as illustrated in this case.

    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

    The current disparity of viable organs and patients in need of a transplant has been an impetus for innovative measures. Live donor renal transplantation offers significant advantages compared with cadaveric donor transplantation: increased graft and patient survival, diminution in incidence of delayed graft function, acute tubular necrosis (ATN), and reduction in waiting time. Notwithstanding these gains live donors continue to be underutilized and account for only approximately one quarter of all renal transplants performed in the United States. It has been felt that inherent disincentives to live donation have slowed its growth. These include degree and duration of postoperative pain and convalescence, child care concerns, cosmetic concerns, and time until return to full activities and employment. In an attempt to curtail the disincentives to live donation, laparoscopic live donation (laparoscopic donor nephrectomy; LDN) was developed. The purpose of this study was to compare the results of our first 25 laparoscopic nephrectomies (performed over a 10-month period from September 1998 through July 1999) with the previous 25 standard open donor nephrectomies (ODNs) completed over the past 3 years. We conducted a retrospective review of all donor nephrectomies and recipient pairs performed over the past 3 years. End points included sex, operative time, length of stay, immediate and long-term renal function, and willingness to donate. There were no differences in demographics of the ODN versus the LDN group. The average length of stay was 2.48+/-0.72 days for the LDN versus 4.08+/-0.28 days for the ODN. ODN and LDN have comparable short- and long-term function with no delayed graft function and no complications. Growth of living donor transplant has increased from 16 per cent of all kidney transplants performed in 1995 to 23 per cent in 1999. We conclude that LDN is a viable alternative to the standard donor operation. LDN has had a positive impact on the donor pool

    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.

    With the increasing number of patients being offered kidney transplantation by many centers in the developing world, it is not unexpected that there would be attendant ethical and legal issues even when the selection process for transplantation seems medically justified. Because of the inadequate infrastructure for hemodialysis and peritoneal dialysis, coupled with the challenges of logistics for maintenance dialysis, transplantation would seem to be the best option for patients with end-stage renal failure, even in developed economies where these can easily be tackled. The main issues here revolve around incentives for donors, organ trade and trafficking and the economics of eliminating the waiting list and the criminal activities of organ trans-plantation. In the developing world, with the current level of corruption and poverty, there is a need to redouble efforts to monitor transplant activities. Professional bodies should take the lead in this regard. Furthermore, there is a need for governments to engage in public consultation and community awareness concerning organ donation in living and deceased persons. PMID:26787578

    2016-01-01

    Full Text Available The aim of the study was to determine the value of extracorporeal photochemotherapy (EPCT in the induction of tissue tolerance in renal transplantation. EPCT was applied to 24 renal transplant recipients in early postoperative period, the control group consisted of paired transplant recipients. In the group using EPCT over a three-year period of observation no clinical or histological signs of rejection were observed. In the control group, histologically confirmed rejection was observed in 4 cases, in 2 cases transplantectomy due to acute rejection. The reducing incidence of infectious complications in the study group compared with the control one (4 and 19 cases, respectively and decreasing number of hospitalizations on various reasons (8 and 47 cases in the study and control groups, respectively were also noted. Three-year graft survival was 100% and 83.3% in the study and the control groups, respectively. Using immunological tests in 30 days after transplantation the stable number of cells expressing coactivation molecules (57.7 ± 18.2 and 52.7 ± 23.2%, respectively, p > 0.05 and the density of their co-expression (22.7 ± 6.0 and 19.6 ± 7.0 units, respectively, p > 0.05 were demonstrated, while in the study group, the pronounced and statistically significant reduction both in the amount of cells expressing co-activation receptors (from 57.7 ± 18.2 to 34.5 ± 11.4%, p < 0.05 and in the density of these receptors on naive helper T-lymphocytes (from 22.7 ± 6.0 to 16.8 ± 5.1 units, p < 0.05 was revealed. Thus, it is noted that EPCT provides induction of tolerance to MHC antigens in kidney transplantation due to reducing expression of coactivation molecules which promote the second signaling pathway to T-cell receptor activation.

    We studied by microscopy 377 biopsies, nephrectomies, and necropsy kidneys from 123 human renal transplants. We discovered two common abnormalities of the renal corpuscle, both affecting the glomerulo-tubular junction. Adhesion of the tip of the glomerular tuft to the origin of the tubule, as reported in various non-transplant glomerulopathies, was seen in 197 specimens (52 per cent). This change was common in material showing acute or chronic vascular rejection and glomerulopathy, and was almost universal in transplants that had been in place for over 1 year. Another change at the glomerulo-tubular junction, not previously highlighted, consisted of an infiltrate of lymphocytes or neutrophil polymorphs into the epithelium at the tubular origin. This change was seen in 145 specimens (38 per cent) and was associated with cellular rejection and ascending infection. These changes are of importance because they show two responses of the kidney to injury that involve the glomerulo-tubular junction and thus suggest that this part of the kidney has some specific properties that have been largely neglected up to now.

    Full Text Available Background: The chronic use of immunosuppressants in renal transplant recipients (RTRs predisposes them to a variety of skin manifestations. Studies on skin lesions in RTRs from India have been limited. Aim: To study the prevalence and clinical spectrum of skin diseases in RTR in patients attending the Nephrology clinic of a tertiary care hospital in South India. Methods: Between October 2002 and June 2003, 365 RTRs were evaluated for skin lesions, including 280 examined after renal transplant (group A and 85 examined once before and then monthly after transplant for a period of 6 months (group B. Results: A total of 1163 skin lesions were examined in 346 RTRs (94.7% including lesions of aesthetic interest (LAI [62.3%] followed by infections [27.3%]. All LAI were drug-related manifestations, making it the most common skin lesion, while fungal (58.7% and viral (29.3% infections constituted majority of lesions caused by infection. Lesions related to neoplasms were relatively uncommon (2.1% and all lesions were benign. Miscellaneous lesions constituted 8.3% of skin lesions, which included vaccine-induced necrobiotic granulomas at the site of Hepatitis B vaccination and acquired perforating dermatoses. Conclusion: Skin lesions among RTRs from India consist predominantly of drug-related LAI and infections and are different from the West in view of the paucity of neoplastic lesions.

  2. Diagnosis and management of ureteral complications following renal transplantation

    2015-10-01

    Full Text Available When compared with maintenance dialysis, renal transplantation affords patients with end-stage renal disease better long-term survival and a better quality of life. Approximately 9% of patients will develop a major urologic complication following kidney transplantation. Ureteral complications are most common and include obstruction (intrinsic and extrinsic, urine leak and vesicoureteral reflux. Ureterovesical anastomotic strictures result from technical error or ureteral ischemia. Balloon dilation or endoureterotomy may be considered for short, low-grade strictures, but open reconstruction is associated with higher success rates. Urine leak usually occurs in the early postoperative period. Nearly 60% of patients can be successfully managed with a pelvic drain and urinary decompression (nephrostomy tube, ureteral stent, and indwelling bladder catheter. Proximal, large-volume, or leaks that persist despite urinary diversion, require open repair. Vesicoureteral reflux is common following transplantation. Patients with recurrent pyelonephritis despite antimicrobial prophylaxis require surgical treatment. Deflux injection may be considered in recipients with low-grade disease. Grade IV and V reflux are best managed with open reconstruction.

    Full Text Available Renal transplantation is performed in patients with end stage renal disease as the best treatment plan. However, different complications may occur in these patients due to the direct consequences of the renal disease or drug-induced suppression of the body immune system. The main objective of the present study was to compare different oral lesions in patients receiving renal transplantation with the patients undergoing dialysis referred to two hospitals in Tehran, Iran.In this cross-sectional study, 93 renal transplant patients who had received renal transplant at least 6 months prior to our study, were selected from their records at the hospitals. Furthermore, 93 candidates of renal transplantation were selected as the control group. The patients in both case and control groups underwent oral examinations and the results were analyzed by chi-square test and Spearman correlation coefficient.At least one oral lesion was found in 30 (32.2% patients in the renal transplant group and 8 (8.6% patents in the control subjects. The difference between the two groups was statistically significant (p<0.0001. The most prevalent lesion was xerostomia observed in 20 patients of the renal transplant group and 4 patients in the control group. The odds ratio of cyclosporine and amlodipine and the effect of these in increasing the risk of oral lesions was 1.21 and 1.02, respectively in renal transplant recipients.The results of the study showed that renal transplantation significantly increases the risk of related oral lesions. Therefore, renal transplant recipients must undergo regular oral examinations in order to find any suspicious lesion(s as soon as possible to treat them.

    2009-06-01

    Full Text Available Abstract Background Post-transplant anaemia remains a common problem after kidney transplantation, with an incidence ranging from nearly 80% at day 0 to about 25% at 1 year. It has been associated with poor graft outcome, and recently has also been shown to be associated with increased mortality. Our transplant unit routinely administers oral iron supplements to renal transplant recipients but this is frequently accompanied by side effects, mainly gastrointestinal intolerance. Intravenous iron is frequently administered to dialysis patients and we sought to investigate this mode of administration in transplant recipients after noticing less anaemia in several patients who had received intravenous iron just prior to being called in for transplantation. Methods This study is a single-centre, prospective, open-label, randomised, controlled trial of oral versus intravenous iron supplements in renal transplant recipients and aims to recruit approximately 100 patients over a 12-month period. Patients will be randomised to receive a single dose of 500 mg iron polymaltose (intravenous iron group or 2 ferrous sulphate slow-release tablets daily (oral iron group. The primary outcome is time to normalisation of haemoglobin post-transplant. Prospective power calculations have indicated that a minimum of 48 patients in each group would have to be followed up for 3 months in order to have a 90% probability of detecting a halving of the time to correction of haemoglobin levels to ≥110 g/l in iron-treated patients, assuming an α of 0.05. All eligible adult patients undergoing renal transplantation at the Princess Alexandra Hospital will be offered participation in the trial. Exclusion criteria will include iron overload (transferrin saturation >50% or ferritin >800 μg/l, or previous intolerance of either oral or intravenous iron supplements.

    Full Text Available Introduction. Horseshoe kidney is a congenital anomaly that presents unique challenges for the transplant surgeon. The mere presence of horseshoe kidney should not preclude consideration for transplantation. Case Report. A 33-year-old women suffering from end-stage renal disease underwent deceased donor renal transplant with a divided horseshoe kidney. We present a postoperative complication and the technical strategy for transplant salvage. The patient currently has excellent graft function. Discussion. Horseshoe kidneys do present challenges for successful transplantation. Though case reports of successful transplantation are increasing, we present a technical complication and successful transplant salvage strategy. Technical descriptions in the literature of successful back-table preparation strategies should help more transplant surgeons to begin to utilize this resource. Conclusion. This study concludes that horseshoe kidneys can be successfully used for transplantation and provides a technical strategy to salvage the transplant after a unique complication associated with these donor kidneys.

    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.

    Chronic illnesses can cause wide range of personality and behavioral disorders and require appropriate evaluation. Poor patient compliance with prescribed medications and other aspects of management can affect the outcome towards undesirable situation. The setting of renal transplantation presents a broad spectrum of problems and consequences. People involved (patients, their families or treating physicians) have lifelong commitment with evaluation and implementation of measures towards resolving the issues. Psychiatric evaluation is part of this scenario, which starts with evaluation of organ recipient along with donor and family as whole, right from time of diagnosis of end organ failure to transplant and then lifelong. This review highlights common issues faced at different stages of this lengthy pathway. PMID:26664203

    Evaluation of renal transplants by nuclear medicine techniques has been important in differential diagnosis of medical and surgical complications of the early post-transplantation period and in the long-term follow up, mainly in patients with anuric acute tubular necrosis and in patients with developing chronic rejection. Early recognition of this condition should permit treatment and delay of retransplantation. It is recommended to perform a flow study, scintigraphy of the kidneys, prevoid and postvoid bladder images, time activity curves of the graft and bladder and quantitative data of perfusion function and tracer transit. {sup 99m}Tc-MAG3 and {sup 99m}Tc-DTPA can be used for this studies.

    Feeding through a gastrostomy button (GB) provides benefits to the families of children on chronic dialysis. But data on the transition to oral feeding following renal transplantation--especially in children under 2--is scarce. Here, we report our experience of more than 14 years in 22 children who were GB fed at under 5 years of age (median age: 1.66 years; range: 0.25-4.25 years). We excluded 6 children from the analysis of transition following transplantation because of factors precluding early return to oral feeding--specifically, cognitive impairment and a tongue tie. We compared 10 children who commenced GB feeding at less than 2 years (group 1) with those who commenced at 2-5 years (group 2, n = 6). All 16 children made the transition to normal oral feeding by 10 months post transplantation. Median duration of GB feeding post-transplant in group 1 was 0.3 years (range: 0.1-1.0 years) as compared with 0.2 years (range: 0-0.3 years) in group 2 (p = 0.2). Children with normal cognition and no other precluding factors who have a GB inserted at less than 2 years of age can make a successful transition from GB to oral feeding with no significant delay. Family support should be individualized during this period of potential anxiety. PMID:16983960

  11. Donor-Recipient Size Mismatch in Paediatric Renal Transplantation

    2014-01-01

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

    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...... and 10 women, median age 47 years (range, 25-63 years), were studied in an open randomized crossover trial, comparing a 2-week control period with a 2-week period of once-daily administration of 50 mg of losartan. The main outcome measurements were fractional excretion of uric acid (FE(uric acid)) based...... on 24-hr urine collections and plasma uric acid. RESULTS: The median FE(uric acid) was 5.7% (range, 2.4-10.4%) in the control period with a median change of +0.84% (range, -1.15% to +2.77%) in the losartan period (P

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

    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.

    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.

    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.

    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.

    Despite recent advances in solid organ transplantations, an antibody mediated rejection caused by donor specific antibodies is still a major problem in kidney graft survival. Besides HLA-induced humoral response, antibodies against MICA antigens have recently attracted attention because of their possible role in graft rejection. The aim of our study was to establish whether renal recipients produce antibodies against MICA molecules due to the transplantation and if they are specific for MICA antigens of the donors. MICA antibody screening was performed in 124 kidney recipient sera. 22 sera, that were found to be MICA antibody positive, were further examined for MICA antibody profiles and compared with donor MICA alleles. The analysis of MICA antibody positive sera showed mostly more complex reactivity patterns. A significant fraction of patient sera (59%) reacted not only with the donor MICA antigens, but also with other MICA patterns. A match between antibody specificities and MICA antigens was observed in 41% of renal recipients only. On the other hand, as much as in 36% of recipient sera were detected antibodies against their own MICA molecules. We did not prove a complete correlation between the recipient MICA antibody specificities and MICA antigens of the donor. We assume that MICA antibody induction occurs not only due to the allogeneic stimulation itself but also due to other factors that need to be elucidated.

    Acute rejection (AR) remains the primary risk factor for renal transplant outcome; development of non-invasive diagnostic biomarkers for AR is an unmet need. We used shotgun proteomics using LC-MS/MS and ELISA to analyze a set of 92 urine samples, from patients with AR, stable grafts (STA), proteinuria (NS), and healthy controls (HC). A total of 1446 urinary proteins were identified along with a number of NS specific, renal transplantation specific and AR specific proteins. Relative abundance of identified urinary proteins was measured by protein-level spectral counts adopting a weighted fold-change statistic, assigning increased weight for more frequently observed proteins. We have identified alterations in a number of specific urinary proteins in AR, primarily relating to MHC antigens, the complement cascade and extra-cellular matrix proteins. A subset of proteins (UMOD, SERPINF1 and CD44), have been further cross-validated by ELISA in an independent set of urine samples, for significant differences in the abundance of these urinary proteins in AR. This label-free, semi-quantitative approach for sampling the urinary proteome in normal and disease states provides a robust and sensitive method for detection of urinary proteins for serial, non-invasive clinical monitoring for graft rejection after

    Renal transplantation is well established in the USA, Europe, India, and South Africa. However, it is still in its infancy in Nigeria. The objective of our study is to determine the knowledge, awareness, and acceptability of renal transplant among patients with end-stage renal disease (ESRD) and the factors which are responsible for the low level of transplantation in Ibadan, Nigeria. A 15-item pilot-tested questionnaire was administered to willing patients with ESRD seen at the medical outpatient clinic of the University Teaching Hospital, from January to December 2011. There was 81% participation rate of the respondents. Exactly 90.1% had formal education and 44% earned Nigeria, 39.5% had no idea and in 27.2% of the respondents, the fear of death by potential donors may be responsible. Eleven percent of responded that recipients had no money for kidney transplantation and another 11% thought the potential donors would like to be paid for donating their kidneys. Most of the respondents with ESRD were knowledgeable, aware of, and accepted renal transplantation as the next step to treat chronic renal failure. However, majority of these patients could not afford the cost for renal transplantation. PMID:27424696

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

  15. Central nervous system aspergillus infection complicating renal transplantation

    International Nuclear Information System (INIS)

    A case of catastrophic intracerebral haemorrhage secondary to aspergillus infection in an immunocompromised renal transplant patient is presented. The pathological features and related images are described and the radiology of CNS aspergillus infection is reviewed. A 37-year-old woman was admitted with abdominal pain. She had recently received a cadaveric renal transplant following failure of the previous live donor kidney. Gastroscopy showed changes suspicious of cytomegalovirus (CMV) gastroduodenitis and she was treated with gancyclovir, with resolution of her symptoms. While in hospital her creatinine began to rise. The renal biopsy was suggestive of cyclosporin toxicity and the cyclosporin level was raised 537 mg/mL (normal 160-360 mg/mL). Several days later, she developed slurred speech and weakness in her right arm. Non-contrast CT showed multifocal regions of low attenuation over the right temporal convexity, within the basal ganglia, inferior frontal lobe and corona radiata on the left side. Magnetic resonance imaging on the same day showed multiple areas of high signal on the FLAIR images, some of which contained central areas of low signal. There was no significant enhancement post gadolinium but several of the lesions showed increased signal on the diffusion-weighted images, reflecting cytotoxic oedema. Repeat CT showed an increase in the size of the cerebral lesions with haemorrhagic transformation of the right basal ganglia mass. A further lesion with a peripheral dense rim on the non-contrast images was identified in the right cerebellar hemisphere. The possibility of a vasculitis secondary to a fungal infection was raised. Two days later the patient became comatose with CT showing a large intracerebral haematoma in the left basal ganglia, intraventricular blood and hydrocephalus. The patient died soon afterwards. Post-mortem examination showed multifocal cerebral haemorrhage associated with necrotizing vasculitis and aspergillus infection

    Over a 10 year period, 67 recipients of 71 renal allografts received graft irradiation following the diagnosis of rejection. The majority of kidneys were treated with a total dose of 600 rad, 150 rad per fraction, in 4 daily fractions. Fifty-three kidneys were irradiated following the failure of standard systemic immunosuppression and maximally tolerated antirejection measures to reverse an episode of acute rejection. Twenty-two (42%) of these allografts were noted to have stable (i.e. no deterioration) or improved function 1 month following the treatment with irradiation. Eleven (21%) of these allografts maintained function 1 year following transplantation. Biopsies were obtained of 41 allografts. Of the 24 renal allografts with predominantly cellular rejection, 10 (42%) had the process reversed or stabilized at 1 month following irradiation. Five (21%) of these allografts were functioning at 1 year following irradiation. Rejection was reversed or stabilized in 6 of 17 (35%) allografts at 1 month when the histologic features of renal biopsy suggested predominantly vascular rejection. Local graft irradiation has helped maintain a limited number of allografts in patients whose rejection has failed to respond to systemic immunosuppression. Irradiation may also benefit patients with ongoing rejection in whom further systemic immunosuppression is contra-indicated.

    Calcineurin inhibition with tacrolimus has been used after renal transplantation (RTPL) as rescue therapy for insufficient immunological control or if cyclosporin A (CSA) toxicity occurred. Neurologic side-effects occur but are rare in children, usually presenting as tremor; however, serious complications, e.g. the posterior leukoencephalopathy syndrome are also documented. Twenty children (10 girls) were switched to tacrolimus: 11 (55%) for immunological reasons (n = 9: steroid-resistant rejection; n = 2: recurrent rejections) and nine for CSA side-effects. Tacrolimus was started at a median of 8 wk (range 10 d to 8.7 yr) after RTPL and was continued for a median of 2.5 yr (range 5 wk to 4.6 yr). Renal function significantly improved over a period of 12 months following conversion to tacrolimus (glomerular filtration rate 56 +/- 19 vs. 66 +/- 16 mL/min/1.73 m2; p side-effects were neuropsychological and behavioral symptoms in three children, ranging from anorexia nervosa-like symptoms with weight loss, amenorrhea, depression and school problems to severe insomnia and to aggressive and anxious behavior in one child. Only the latter child was exposed to toxic tacrolimus blood levels. All side-effects were fully reversible after discontinuation of tacrolimus. In conclusion, tacrolimus had a beneficial effect on renal function and was well tolerated in the majority of pediatric patients. However, neuropsychologic and behavioral side-effects are important and maybe underrecognized in children. PMID:12709079

    Full Text Available INTRODUCTION: Renal interstitial fibrosis (RIF is a significant cause of end-stage renal failure. The goal of this study was to characterize the distribution of transplanted induced autologous stem cells in a rabbit model of renal interstitial fibrosis and evaluate its therapeutic efficacy for treatment of renal interstitial fibrosis. METHODS: A rabbit model of renal interstitial fibrosis was established. Autologous fibroblasts were cultured, induced and labeled with green fluorescent protein (GFP. These labeled stem cells were transplanted into the renal artery of model animals at 8 weeks. RESULTS: Eight weeks following transplantation of induced autologous stem cells, significant reductions (P < 0.05 were observed in serum creatinine (SCr (14.8 ± 1.9 mmol/L to 10.1 ± 2.1 mmol/L and blood urea nitrogen (BUN (119 ± 22 µmol/L to 97 ± 13 µmol/L, indicating improvement in renal function. CONCLUSIONS: We successfully established a rabbit model of renal interstitial fibrosis and demonstrated that transplantation of induced autologous stem cells can repair kidney damage within 8 weeks. The repair occurred by both inhibition of further development of renal interstitial fibrosis and partial reversal of pre-existing renal interstitial fibrosis. These beneficial effects lead to the development of normal tissue structure and improved renal function.

  2. The tacrolimus metabolism rate influences renal function after kidney transplantation.

    Full Text Available The effective calcineurin inhibitor (CNI tacrolimus (Tac is an integral part of the standard immunosuppressive regimen after renal transplantation (RTx. However, as a potent CNI it has nephrotoxic potential leading to impaired renal function in some cases. Therefore, it is of high clinical impact to identify factors which can predict who is endangered to develop CNI toxicity. We hypothesized that the Tac metabolism rate expressed as the blood concentration normalized by the dose (C/D ratio is such a simple predictor. Therefore, we analyzed the impact of the C/D ratio on kidney function after RTx. Renal function was analyzed 1, 2, 3, 6, 12 and 24 months after RTx in 248 patients with an immunosuppressive regimen including basiliximab, tacrolimus, mycophenolate mofetil and prednisolone. According to keep the approach simple, patients were split into three C/D groups: fast, intermediate and slow metabolizers. Notably, compared with slow metabolizers fast metabolizers of Tac showed significantly lower estimated glomerular filtration rate (eGFR values at all the time points analyzed. Moreover, fast metabolizers underwent more indication renal biopsies (p = 0.006 which revealed a higher incidence of CNI nephrotoxicity (p = 0.015 and BK nephropathy (p = 0.024 in this group. We herein identified the C/D ratio as an easy calculable risk factor for the development of CNI nephrotoxicity and BK nephropathy after RTx. We propose that the simple C/D ratio should be taken into account early in patient's risk management strategies.

    The effective calcineurin inhibitor (CNI) tacrolimus (Tac) is an integral part of the standard immunosuppressive regimen after renal transplantation (RTx). However, as a potent CNI it has nephrotoxic potential leading to impaired renal function in some cases. Therefore, it is of high clinical impact to identify factors which can predict who is endangered to develop CNI toxicity. We hypothesized that the Tac metabolism rate expressed as the blood concentration normalized by the dose (C/D ratio) is such a simple predictor. Therefore, we analyzed the impact of the C/D ratio on kidney function after RTx. Renal function was analyzed 1, 2, 3, 6, 12 and 24 months after RTx in 248 patients with an immunosuppressive regimen including basiliximab, tacrolimus, mycophenolate mofetil and prednisolone. According to keep the approach simple, patients were split into three C/D groups: fast, intermediate and slow metabolizers. Notably, compared with slow metabolizers fast metabolizers of Tac showed significantly lower estimated glomerular filtration rate (eGFR) values at all the time points analyzed. Moreover, fast metabolizers underwent more indication renal biopsies (p = 0.006) which revealed a higher incidence of CNI nephrotoxicity (p = 0.015) and BK nephropathy (p = 0.024) in this group. We herein identified the C/D ratio as an easy calculable risk factor for the development of CNI nephrotoxicity and BK nephropathy after RTx.

    Hyperhomocysteinemia, a risk factor for vascular disease, is found in children as well as in 80% of adult patients with end-stage renal disease. The aim of this study was to assess the changes in plasma homocysteine concentrations after renal transplantation (RT). Plasma homocysteine, vitamin B(12), and folate concentrations were prospectively measured in six patients at three points, before and post transplantation (6 months, 4 years), and compared with controls using standardized scores (Z score) for each of these parameters. Folic acid supplementation was introduced after the evaluation at 6 months. Patients had elevated median plasma homocysteine Z scores during dialysis (4.12). When assessed at 6 months and 4 years, median plasma homocysteine Z scores were, respectively, 2.35 and 0.29. Median folate Z scores were 1.89 during dialysis, -0.26 at 6 months, and 3.26 at 4 years post RT. Median vitamin B(12) Z score was 2.12 during dialysis, 0.58 at 6 months, and -0.07 at 4 years post RT. Glomerular filtration rate (GFR) improved after RT, with median GFR of 84.5 ml/min per 1.73 m(2) at 6 months. This stabilized to a value of 70.5 ml/min per 1.73 m(2) at 4 years. When comparing values before and after RT at 6 months, changes were observed only for GFR ( P<0.03) and vitamin B(12) ( P<0.05). There were no changes in plasma homocysteine, folate, and serum albumin. At 4 years, a significant decrease in plasma homocysteine was observed ( P<0.05) with increased GFR ( P<0.03). No significant changes were observed in plasma albumin, folate, and vitamin B(12) concentrations. In conclusion, elevated plasma homocysteine in children during dialysis persists after RT despite a significant improvement in renal function. However, normalization was attained when patients were supplemented with folic acid. Further controlled studies are required to evaluate the determinants and treatment of elevated plasma homocysteine in pediatric transplant patients. PMID:12172766

    Full Text Available Fernando Giron, Yenny BaezKidney Transplant Service, Colombiana de Trasplantes, Bogota, ColombiaAbstract: Everolimus is a proliferation inhibitor designed to target chronic allograft nephropathy including prevention of acute rejection. Acute renal allograft rejection incidence varies with the therapy used for immunosuppression. Registry data show that 15% to 35% of kidney recipients will undergo treatment for at least one episode of acute rejection within the first post-transplant year. Everolimus has been used as therapy with full- or reduced-dose cyclosporine A without evidence of increasing the acute rejection incidence. This review will summarize the available clinical trial data on the use of everolimus and its role in preventing acute rejection incidence in renal transplantation.Keywords: calcineurin inhibitors, cyclosporine, everolimus, biopsy-proven acute rejection, renal transplantation, acute rejection

  6. Managing new-onset gout in pediatric renal transplant recipients: when, how, to what extent.

    Hyperuricemia and gout are common among adult renal transplant recipients, but it is rarely reported following pediatric renal transplantations. Treating gout in pediatric kidney transplant recipients presents clinical challenges to the management of both immunosuppressive regimen and hyperuricemia for their effects on serum uric acid levels, renal function and drug interactions. Most renal transplant recipients have a relative impairment of renal clearance of urate due to abnormalities in renal transport, explaining the association of hyperuricemia and decreased glomerular filtration rate. Risk factors for the development of gout include impaired renal function, hypertension, heart failure and diabetes mellitus. Calcineurin inhibitors, particularly cyclosporine, are the most important risk factor for gout in transplant recipients and should not be used in pediatric renal transplant recipients. Diuretic therapy increases the risk of gout by causing extracellular volume contraction with consequent enhancement of proximal tubular reabsorption. Corticosteroids are increasingly replacing nonsteroidal antiinflammatory drugs and colchicine for the treatment of acute gout flares because they have little effect on kidney function. Proper management is aimed at lowering serum uric acid level below 6.0 mg/dL with xanthine oxidase inhibitors such as allopurinol or febuxostat. Allopurinol and mycophenolate mofetil are safer to use in combination than are allopurinol and azathioprine. Febuxostat is an alternative to allopurinol in patients with allopurinol intolerance or hypersensitivity. Pegloticase is indicated for patients with severe gout in whom allopurinol and febuxostat have not been effective or tolerated. PMID:22941874

    Full Text Available Introduction:There is scarce information regarding clinical evolution of HBV infection in renal transplant patients.Aims:To evaluate the prevalence of acute exacerbation in HBV-infected renal transplant patients and its association with the time after transplantation, presence of viral replication, clinical evolution, and use of antiviral prophylaxis.Materials and methods:HBV infected renal transplant patients who underwent regular follow-up visits at 6-month intervals were included in the study. The criteria adopted to characterize exacerbation were: ALT >5 × ULN and/or >3 × baseline level. Predictive factors of exacerbation evaluated were age, gender, time on dialysis, type of donor, post-transplant time, ALT, HBeAg, HBV-DNA, HCV-RNA, immunosuppressive therapy, and use of antiviral prophylaxis.Results:140 HBV-infected renal transplant patients were included (71% males; age 46 ±10 years; post-renal transplant time 8 ±5 years. During follow-up, 25% (35/140 of the patients presented exacerbation within 3.4 ±3 years after renal transplant. Viral replication was observed in all patients with exacerbation. Clinical and/or laboratory signs of hepatic insufficiency were present in 17% (6/35 of the patients. Three patients died as a consequence of liver failure. In univariate analysis variables associated with exacerbation were less frequent use of prophylactic/preemptive lamivudine and of mycophenolate mofetil. Lamivudine use was the only variable independently associated with exacerbation, with a protective effect.Conclusions:Acute exacerbation was a frequent and severe event in HBV-infected renal transplant patients. Prophylactic/preemptive therapy with antiviral drugs should be indicated for all HBsAg-positive renal transplant patients.

    Acute antibody mediated rejection (AMR) is one of the most important complications after kidney transplantation. Renal graft biopsy is safe and reliable without adverse effects on the patients and transplanted kidneys, which was of great instructive significance in diagnosis and treatment of renal allograft dysfunction after renal transplantation. This paper reported a case series of 106 patients underwent renal allograft biopsies. All biopsies were evaluated according to the Banff 2007 schema. 52 examples were obtained within 1 month after transplantation, and there were another 20 examples in one to two months and other 34 examples in two to three months. Appropriate therapy was applied and clinical outcomes were observed. All patients received renal biopsies and anti-inflammatory and hemostasis treatment without complications. There were 2 cases of hyperacute rejection, and 15 cases of acute AMR. All Paraffin-embedded samples were stained by HE, periodic acid-Schiff (PAS), Masson, and immunohistochemistry (C4d, cd20, cd45RO, SV40). All samples were found C4d immunohistochemical staining positive. Patients with acute AMR were managed by steroid intravenous pulse therapy, Rabbit anti-thymocyte globulin intravenous pulse therapy, anti CD20 monoclonal antibody intravenous therapy and so on. Two cases of hyperacute rejection had renal failure, and received kidney excision; 12 cases in 15 cases of AMR recovered, another 2 cases did not recover with high-level creatine, and other 2 cases of renal allograft received excision.

    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.

    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.

    Objective:To investigate the clinical application of sirolimus (SRL) in renal post-transplant which included sirolimus in place of mycophenolate mofetil. Their clinical course was evaluated during the first 6 months after surgery. Maintenance immunosuppression included sirolimus, corticosteroid and cyclosporine. Sirolimus dosing was initiated at 6 mg on the first day, from then on 1.2-1.5 mg as a single daily dose and adjusted to maintain the levels at 5-15 ng/ml. 25 cases were treated with SRL combined group). Results: Patients' graft survival rate was 100%. There was no significant difference in average serum creatinine level and incidence of acute rejection between SRL group and MMF group[10.0% (2/20)vs 11.4% (4/35), P>0. 05]. During the follow-up period, the incidence of side effect was similar in SRL group or MMF group, except for hyperlipidemia in SRL group. Sirolimus was discontinued in 5 patients for adverse events predominantly for numbness of oral lip, delayed renal allograft function, poor wound healing, liver or kidney function injury and pneumonitis. Conclusion: Early outcomes with sirolimus were acceptable with 100% graft survival and 10. 0% incidence of acute rejection. However, because of adverse events including poor wound healing and pneumonitis, the immunosuppression regimen of SRL combined with low dose of CsA has been limited to clinical application in some degree in early transplant recipients. As one of therapeutical choices, it has been a long way to investigate SRL in clinical extension.

    In 1989, 22 children (11 boys, 11 girls aged 8-23 years) with nephropathic cystinosis, who had received a total of 28 renal allografts over the previous 14 years, were reviewed. Nineteen were alive, of whom 17 had functioning grafts 5 months to 13 years after transplantation. The mean serum creatinine level in these 17 was 135 mumol/l. Patient and graft survival did not differ from non-cystinotic children. Persistent hypothyroidism was found in 3 patients, transient diabetes mellitus in 1, severely disturbed vision in 1 and brain atrophy in 11. Arterial hypertension was present in 16 patients. Growth retardation was universal, although in 4 patients on cyclosporin A post-transplant catch-up growth occurred. Five patients over 15 years completed puberty. Readjustment in terms of school performance was good but was less good for psychosocial development. None of the patients had ever been treated with cystine-depleting agents; the data will therefore provide a historical control group with which to compare the results from a group treated with these agents.

    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.

    CKD is a frequent long-term complication after SBTx. CNIs are a well-known factor, but probably not the only cause. We assessed the incidence, risk factors, and severity of CKD in 27 children with SBTx (15 combined liver/SBTx) and prednisone/TAC-based maintenance immunosuppression. Median follow-up was seven yr (3-21). A renal biopsy was performed in 14 patients, 1-18 yr post-SBTx. A reduced GFR was observed in 17 children (63%) during the follow-up with none requiring dialysis. CNI toxicity was observed in 11/14 biopsies, as early as two yr post-transplant, and could occur with a normal mGFR. The dose of TAC was reduced by 50% in 13 patients with CKD and/or significant kidney histological lesions, and six were also given MMF. This led to a significant improvement in renal function: mGFR normalized in eight patients and improved or stabilized in five. No rejection occurred. At last follow-up, 37% had CKD stage 2 and 15% had CKD stage 3. In conclusion, CKD is frequent in children after SBTx and probably multifactorial. Less nephrotoxic immunosuppressive protocols may improve mGFR and should be further considered. The kidney histology helps in designing personalized immunosuppression strategies for patients.

    The human urinary proteome reflects systemic and inherent renal injury perturbations and can be analyzed to harness specific biomarkers for different kidney transplant injury states. 396 unique urine samples were collected contemporaneously with an allograft biopsy from 396 unique kidney transplant recipients. Centralized, blinded histology on the graft was used to classify matched urine samples into categories of acute rejection (AR), chronic allograft nephropathy (CAN), BK virus nephritis (BKVN), and stable graft (STA). Liquid chromatography–mass spectrometry (LC-MS) based proteomics using iTRAQ based discovery (n=108) and global label-free LC-MS analyses of individual samples (n=137) for quantitative proteome assessment were used in the discovery step. Selected reaction monitoring (SRM) was applied to identify and validate minimal urine protein/peptide biomarkers to accurately segregate organ injury causation and pathology on unique urine samples (n=151). A total of 958 proteins were initially quantified by iTRAQ, 87% of which were also identified among 1574 urine proteins detected in LC-MS validation. 103 urine proteins were significantly (p<0.05) perturbed in injury and enriched for humoral immunity, complement activation, and lymphocyte trafficking. A set of 131 peptides corresponding to 78 proteins were assessed by SRM for their significance in an independent sample cohort. A minimal set of 35 peptides mapping to 33 proteins, were modeled to segregate different injury groups (AUC =93% for AR, 99% for CAN, 83% for BKVN). Urinary proteome discovery and targeted validation identified urine protein fingerprints for non-invasive differentiation of kidney transplant injuries, thus opening the door for personalized immune risk assessment and therapy.

    Full Text Available BACKGROUND: Chronic transplant dysfunction explains the majority of late renal allograft loss and is accompanied by extensive tissue remodeling leading to transplant vasculopathy, glomerulosclerosis and interstitial fibrosis. Matrix proteoglycans mediate cell-cell and cell-matrix interactions and play key roles in tissue remodeling. The aim of this study was to characterize differential heparan sulfate proteoglycan and chondroitin sulfate proteoglycan expression in transplant vasculopathy, glomerulosclerosis and interstitial fibrosis in renal allografts with chronic transplant dysfunction. METHODS: Renal allografts were transplanted in the Dark Agouti-to-Wistar Furth rat strain combination. Dark Agouti-to-Dark Agouti isografts and non-transplanted Dark Agouti kidneys served as controls. Allograft and isograft recipients were sacrificed 66 and 81 days (mean after transplantation, respectively. Heparan sulfate proteoglycan (collXVIII, perlecan and agrin and chondroitin sulfate proteoglycan (versican expression, as well as CD31 and LYVE-1 (vascular and lymphatic endothelium, respectively expression were (semi- quantitatively analyzed using immunofluorescence. FINDINGS: Arteries with transplant vasculopathy and sclerotic glomeruli in allografts displayed pronounced neo-expression of collXVIII and perlecan. In contrast, in interstitial fibrosis expression of the chondroitin sulfate proteoglycan versican dominated. In the cortical tubular basement membranes in both iso- and allografts, induction of collXVIII was detected. Allografts presented extensive lymphangiogenesis (p<0.01 compared to isografts and non-transplanted controls, which was associated with induced perlecan expression underneath the lymphatic endothelium (p<0.05 and p<0.01 compared to isografts and non-transplanted controls, respectively. Both the magnitude of lymphangiogenesis and perlecan expression correlated with severity of interstitial fibrosis and impaired graft function

    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 posttransplant month 1 and 3 (P < 0.01).Patients with ERD had much higher pre-transplant serum creatinine levels (P < 0.001) and longer duration of pre-transplant renal insufficiency (P < 0.001) than those without ERD.Pretransplant 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 < 0.001] and BMI (OR =6.358,P =0.002) were identified as independent risk factors for PTHL by multivariate analysis.CONCLUSION:Renal function is closely associated with the development of PTHL in LDLT.Post-transplant renal dysfunction,which mainly results from pre-transplant renal insufficiency,contributes to PTHL.

    proximal and distal tubular handling of sodium (and water) were comparable between the two groups of patients. Dopamine caused significant natriuresis in both groups. 5. In conclusion, low-dose cyclosporin A seems not to attenuate the renal haemodynamic and tubular response to infusions of amino acids......1. The nephrotoxic effects of cyclosporin A may diminish the ability of the transplanted kidney to increase the glomerular filtration rate and effective renal plasma flow during infusion of dopamine or amino acids. 2.

    Since 1965, more than 2000 renal transplantations (including more than 100 living-donor transplantations) have been performed at the University of Brussels. An end-stage renal disease patient candidate to renal transplantation will be therefore followed from his enrolment on the waiting list to the long-term post-transplant period. Improvement in the outcome of renal transplantation is achieved due to better knowledge in many fields of medicine, such as immunology, infectious disease, metabolic diseases (hyperlipemia, diabetes mellitus), pharmacology, use of immunosuppressive regimen, a more adequate cardiovascular prevention and treatment. If the best results were achieved with kidneys from living donors, the graft survival rate at the University of Brussels was nearly 80% for the last period (2000-2006). Unfortunately, renal transplantation cannot cure certain comorbid conditions and even may promote them: infectious diseases, neoplasia, metabolic disorders (e.a diabetes mellitus, hyperlipemia). Many efforts have to be done to develop less toxic and more immune selective therapeutic strategies. Living donation and extension of the pool of cadaveric donors will reduce the length of time spent on the waiting list and will significantly impact on mortality and morbidity after kidney transplantation.

    2006-10-01

    The pharmacodynamic (PD) action of tacrolimus (FK) within the T-cell is inhibition of calcineurin phosphatase (CaN). Determination of CaN activity provides us with an important PD marker. Eleven renal transplant patients treated with FK were investigated on day 14 following transplantation and 5 years later. Blood samples drawn before as well as 1, 2, 3, and 4 hours after oral intake of FK were analyzed for CaN activity and blood FK concentrations. Twenty healthy subjects had one blood sample drawn for CaN activity, which was measured as the release of (32)P from a phosphorylated peptide. Radioactivity of (32)P was quantitated by liquid scintillation counting with the results converted to units of CaN utilizing a calibration curve. On day 14, we observed significant inhibition of CaN activity at T:1, 2, and 3 compared with the predose level (P = .002; P = .015; P = .015). Furthermore, all measured CaN activities were significantly different from those observed in healthy nonmedicated subjects. In contrast, at 5 years posttransplant only the CaN activity at T:2 was significantly inhibited compared with the predose level (P = .02). Additionally, all CaN activities at this time were not significantly different from CaN activities in the healthy subjects. We were not able to demonstrate individual CaN activity profiles in the patients. The lack of CaN inhibition at 5 years after transplantation despite relevant drug concentrations, probably reflected the lower drug dose used long after transplantation. This result raises the question of whether CaN inhibition is necessary to hold graft function and whether FK possess CaN-independent mechanisms of action. PMID:17098028

    Renal transplant recipients are at an increased risk of developing Methicillin-resistant Staphylococcus aureus due to their immunosuppressed status. Herein, we investigate the incidence of MRSA infection in patients undergoing renal transplantation and determine the effect of MRSA colonisation on renal allograft function and overall mortality. Between January 1st 2007 and December 31st 2012, 1499 consecutive kidney transplants performed in our transplant unit and a retrospective 1:2 matched case-control study was performed on this patient cohort. The 1-, 3- and 5-year overall graft survival rates were 100%, 86% and 78%, respectively, in MRSA positive recipients compared with 100%, 100% and 93%, respectively, in the control group (P renal allograft failure at 5 years (hazard ratio: 4.6, 95% confidence interval: 1-30.7, P = 0.048). These findings demonstrate that the incidence of long-term renal allograft failure is significantly greater in this patient cohort compared with a matched control population.

    Full Text Available Introduction: Children with coronary renal failure had problems with their catch-up growth. The aim of this study was the Assessment of catch-up growth of children after renal transplantation by analyzing the 6 months changes in height deficit and height standard deviation scores (SDS on age, sex, initial height deficit, initial SDS, graft function, renal failure duration and renal transplantation duration. Methods and Materials: Between 22 September 1998 and 2000, 25 pediatric recipients followed up quarterly for height in the Labafi-Nejad hospital. Data on height submitted at each 6-month follow-up were converted into height and SDS. All the results were analyzed by simple and multiple regression and t-test. Results: 68 percents were male and 32 percent were female Mean age at transplantation was 10.39±2.95 SD years. The average duration of renal transplantation was 20.7±8.96 SD months. The aerage of height deficit was 20.7 cm (±10.55 SD and SDS -3.5 (±1.72 SD at the time of renal transplantation. The height deficit was more significant in the patients with tubulopathy. Catch-up growth observed at month 12. That was more obvious in females, in patients with tubulopathy disorders, in preemptives and in all three age groups. Simple and stepwise regression analysis showed that at month 12 only initial height deficit (P<0.05 and at month 24, only sex (P<0.05 were independent predictor of improved height post transplantation. Catch-up growth were seen in more student patients and girls. This may be the result of puberty spurt that occur two years sooner in girls than in boys. Conclusion: In this study we concluded that the renal transplantation alone is not sufficient measure for correction of catch-up growth in renal failure children and because of that the other treatments should come under consideration.

    Full Text Available The aim of our study was to compare the surgical complications and short-term outcome of renal transplants with single and multiple renal artery grafts. We reviewed the records of 105 kidney transplantations performed consecutively at our institution from July 2006 to May 2010. The data of 33 (31.4% renal transplants with multiple arteries were compared with the 72 transplants with single artery (68.6%, and the incidence of surgical complications, post-transplant hypertension, acute tubular necrosis, acute graft rejection, mean creatinine level, and patient and graft survival was analyzed. We further subdivided the study recipients into three groups: group A (n = 72 with one-renal-artery allografts and one-artery anastomosis, group B (n = 6 with mul-tiple-artery allografts with single-artery anastomosis, and group C (n = 27 with multiple-artery allografts with multiple arterial anasatomosis, and compared their outcome. No significant diffe-rences were observed among the recipients of all the three groups regarding early vascular and urological complications, post-transplant hypertension, acute tubular necrosis, acute rejection, creatinine level, and graft and patient survival. The mean cold ischemia time in groups B and C was significantly higher (P <0.05. One patient in group A developed renal vein thrombosis resulting in graft nephrectomy. None of the patients with multiple renal arteries developed either vascular or urological complications. In conclusion, kidney transplantation using grafts with mul-tiple renal arteries is equally safe as using grafts with single renal artery, regarding vascular, urological complications, as well as patient and graft survival.

  5. Disrupted Renal Mitochondrial Homeostasis after Liver Transplantation in Rats.

    Full Text Available Suppressed mitochondrial biogenesis (MB contributes to acute kidney injury (AKI after many insults. AKI occurs frequently after liver transplantation (LT and increases mortality. This study investigated whether disrupted mitochondrial homeostasis plays a role in AKI after LT.Livers were explanted from Lewis rats and implanted after 18 h cold storage. Kidney and blood were collected 18 h after LT.In the kidney, oxidative phosphorylation (OXPHOS proteins ATP synthase-β and NADH dehydrogenase-3 decreased 44% and 81%, respectively, with marked reduction in associated mRNAs. Renal PGC-1α, the major regulator of MB, decreased 57% with lower mRNA and increased acetylation, indicating inhibited synthesis and suppressed activation. Mitochondrial transcription factor-A, which controls mtDNA replication and transcription, protein and mRNA decreased 66% and 68%, respectively, which was associated with 64% decreases in mtDNA. Mitochondrial fission proteins Drp-1 and Fis-1 and mitochondrial fusion protein mitofusin-1 all decreased markedly. In contrast, PTEN-induced putative kinase 1 and microtubule-associated protein 1A/1B-light chain 3 increased markedly after LT, indicating enhanced mitophagy. Concurrently, 18- and 13-fold increases in neutrophil gelatinase-associated lipocalin and cleaved caspase-3 occurred in renal tissue. Both serum creatinine and blood urea nitrogen increased >2 fold. Mild to moderate histological changes were observed in the kidney, including loss of brush border, vacuolization of tubular cells in the cortex, cast formation and necrosis in some proximal tubular cells. Finally, myeloperoxidase and ED-1 also increased, indicating inflammation.Suppression of MB, inhibition of mitochondrial fission/fusion and enhancement of mitophagy occur in the kidneys of recipients of liver grafts after long cold storage, which may contribute to the occurrence of AKI and increased mortality after LT.

    To minimize the recurrence of a previously treated neoplasm in organ recipients, a period of 2 to 5 years without recurrence is advocated for most malignancies. However, prostate cancer is different because of its biological properties, diagnosis, and treatment. Most prostate cancers are detected at a low stage and demonstrate slow growth after detection. Definitive treatment with radical prostatectomy affords excellent results. Renal transplant candidates with early-stage prostate cancer have a higher risk of dying on dialysis than dying from prostate cancer; therefore, renal transplant candidates with organ-confined prostate cancer should be immediately considered for transplant.

    Full Text Available Abstract Introduction Fungal infections in the immunocompromised host are fairly common. Of the mycoses, Fusarium species are an emerging threat. Fusarium infections have been reported in solid organ transplants, with three reports of the infection in patients who had received renal transplants. To the best of our knowledge, this is the first case of an isolated cutaneous lesion as the only form of infection. Case presentation We report the case of a 45-year-old South Indian man who presented with localized cutaneous Fusarium infection following a renal transplant. Conclusion In an immunocompromised patient, even an innocuous lesion needs to be addressed with the initiation of prompt treatment.

    2013-01-01

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

    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.

    Full Text Available Outpatient parenteral antimicrobial therapy (OPAT is a well-established method in medical specialties. Its use in renal transplant recipients has not been thoroughly explored. No guidelines within this patient subset exist. This study describes OPAT outcomes within a UK teaching hospital renal transplant population. Renal function, mapped by estimated glomerular filtration rate (eGFR, and clinical response to infection were collected retrospectively. A total of 635 antimicrobial episodes were administered to nine renal transplant patients over 12 discrete OPAT courses during the study period. Eleven of 12 OPAT courses (91.67% produced a clinical improvement in infection. One course was terminated due to immunosuppressive-related neutropenia. No patient required admission due to failure of OPAT or adverse events. There was no significant change in graft function throughout the OPAT courses compared with baseline renal function (ANOVA, P = 0.06. One minor line infection was reported. This was treated conservatively and did not interrupt the OPAT. OPAT is safe and clinically effective in our renal transplant recipients with no significant deterioration in eGFR. The incidence of adverse events, specifically line complications, was lower in our population than those reported in the literature. Future work should develop OPAT guidelines designed for transplant recipients to outline the degree of monitoring required.

    BACKGROUND: Renal transplantation remains the preferred method of renal replacement therapy in terms of patient survival, quality of life and cost. However, patients have a high risk of complications ranging from rejection episodes, infection and cancer, amongst others. AIMS AND METHODS: In this study, we sought to determine the long-term health outcomes and preventive health measures undertaken for the 1,536 living renal transplant patients in Ireland using a self-reported questionnaire. Outcomes were divided into categories, namely, general health information, allograft-related information, immunosuppression-related complications and preventive health measures. RESULTS: The results demonstrate a high rate of cardiovascular, neoplastic and infectious complications in our transplant patients. Moreover, preventive health measures are often not undertaken by patients and lifestyle choices can be poor. CONCLUSIONS: This study highlights the work needed by the transplantation community to improve patient education, adjust immunosuppression where necessary and aggressively manage patient risk factors.

  18. A survey of medical students to assess their exposure to and knowledge of renal transplantation

    Full Text Available Abstract Background Within the field of renal transplantation there is a lack of qualified and trainee surgeons and a shortage of donated organs. Any steps to tackle these issues should, in part, be aimed at future doctors. Methods A questionnaire was distributed to final year students at a single medical school in the UK to assess their exposure to and knowledge of renal transplantation. Results Although 46% of responding students had examined a transplant recipient, only 14% had ever witnessed the surgery. Worryingly, 9% of students believed that xenotransplantation commonly occurs in the UK and 35% were unable to name a single drug that a recipient may need to take. Conclusions This survey demonstrates a lack of exposure to, and knowledge of, the field of renal transplantation. Recommendations to address the problems with the recruitment of surgeons and donation of organs, by targeting medical students are made.

    Anemia is not uncommon in the post-renal transplant period and has been reported in up to 40% of renal transplant recipients. It is commonly due to drugs and infections. While post-transplantation anemia is usually due to graft dysfunction and drugs such as mycophenolate and cotrimoxazole, tacrolimus is an uncommon cause. Tacrolimus is usually not believed to be significantly myelosuppressive, but it can cause anemia due to thrombotic microangiopathy. A literature review shows a very small number of reported cases of pure red cell aplasia (PRCA) where tacrolimus seemed to be a causative agent. We report a case series of three renal transplant recipients who were on tacrolimus and presented with chronic transfusion requiring anemia due to PRCA. PMID:27478605

    We present a 60-year-old female who underwent living unrelated renal transplantation from her 62-year-old husband. The primary immunosuppression consisted of tacrolimus, mycophenolate mofetil and steroid. We did not recognize any rejection in a histopathological study. The total ischemic time to carry out anastomosis of the two renal arteries was 121 minutes. After hemodialysis 5 times for acute tubular necrosis, her renal function improved. She was discharged on the 33rd postoperative day when her serum cretinine level was 1.0 mg/dl. The graft function was stable at 6 months after transplantation. We discussed living unrelated renal transplantation in the elderly population in Japan. PMID:16910589

    Objective To investigate the effect of prostaglandin E: (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. Indexes of the two groups, including incidence of delayed graft function and acute rejection reaction, volume of urine, serum certaintie (SCr), endogenous certainties clearance rate (CCr), the blood flow resistance in graft as well as blood viscosity (BV), and platelet aggregation rate (PAR), were determined. Results The urinary volume and endogenous certainties clearance rate of the treated group were significantly higher, but the level of SCr, incidence of renal function recovery retardation, BV, PAR and blood flow resistance in graft were significantly lower than these of the control group (P0.05). Conclusion Prostaglandin E1 can improve blood microcirculation and decrease the incidence of renal function recovery retardation. These effects are helpful for recovery of renal function after renal transplantation.

    We investigated the possibility of early postoperative Tc-99m DTPA scintigraphy in predicting long-term renal transplant survival. 64 living donor (LD) grafts were divided into two groups according to the graft function on early post-operative renal scintigraphy. Survival analysis was performed using Kaplan-Meier method and Cox proportional hazard model. Chi-square test was performed to evaluate the difference in the frequency of acute rejection. Cumulative renal transplant survival was decreased in 11 patients with abnormal renal scintigraphy, but it was not statistically significant. Decreased graft function on early post-operative renal scintigraphy was not a predictor of long-term graft survival. The frequency of acute rejection was higher in abnormal scintigraphy group, and the difference was statistically significant. Decreased graft function on early post-operative renal scintigraphy has no direct effect on long-term renal transplant survival in LD transplantation, But it may have an indirect effect through increasing the frequency of acute rejection.

    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.

    The 2005 revised allocation scheme for pediatric renal transplantation made the decision of whether to transplant an available living-donor (LD) kidney or use a deceased-donor (DD) kidney controversial. The aim of this study was to examine kidney allograft utilization, sensitization, and outcomes of pediatric transplant recipients. Between January 2000 and December 2009, 91 consecutive pediatric kidney recipients (transplanted. The LD (n = 38) and DD (n = 53) groups were similar in age, gender, dialysis status at transplant, warm ischemia time, and overall patient survival. LD recipients were more likely to be Caucasian (92 vs. 69%), receive older allografts (39 ± 10 vs. 23 ± 9 yr), and have fewer human leukocyte antigen (HLA) mismatches (3.3 ± 1.6 vs. 4.4 ± 1.5, p transplant was longer for LD recipients (97%, 91%, 87% vs. DD 89%, 79%, 58%, respectively, p transplant, 17 (33%) DD recipients had an available LD (mean age 40 yr). A greater proportion of all patients were moderately (PRA 21-79%) sensitized post-transplant (p organs was likely due to fewer HLA mismatched in this group. Nonetheless, LD organs appear to provide optimal outcomes in pediatric renal transplants when considering the risk of becoming sensitized post-transplant complicating later use of the LD kidney.

    Full text: Combined renal/pancreas transplantation is used in patients with severe type-1 diabetes and renal failure. Many patients have asymptomatic coronary artery disease (CAD). Thus, myocardial perfusion imaging (MPI) is widely used for preoperative risk assessment, however, its value has recently been challenged. The purpose of this study was to determine the predictive value of MPI compared to coronary angiography and/or thirty day perioperative cardiac events (cardiac death, myocardial infarction and unstable angina). We reviewed the MPI in 132 patients that were referred for possible renal pancreas transplantation during the period between 1987 - June 1997. Fifty five patients were excluded because of: still awaiting transplantation (n=19) ongoing medical assessment (n=21), received kidney only transplant (n=6) or other factors (n=9). Thus, 77 patients form the basis of this report. Seventy one patients were transplanted, 5 had coronary angiography and one died before transplantation but with coronary anatomy defined at autopsy. All patients (39 male, 38 female; mean age 37 years) had Tl-201 or Tc-99m MIBI SPECT at Westmead (n=54) or elsewhere (n=23). Patients underwent MPI, a mean of 12.1 months before transplantation and a mean of 6 months before coronary angiography or autopsy. MPI was normal in 64 (83%) and abnormal in 13 (17%) patients. Of the abnormal MPI, 7 patients had CAD and one had unstable angina post-operatively (PPV = 8/13; 61%). One patient had a fixed defect post CABG but proceeded to transplant with-out event; the other 4 patients had normal coronary anatomy. Of the normal MPIs there were no transplant related cardiac events, but one patient required CABG >12 months post MPI and a further patient died >12 months post transplant and was shown to have CAD at autopsy (NPV=62/64;97%). In conclusion we have found an excellent NPV and an acceptable PPV for MPI in potential renal pancreas graft recipients

    Prolonged immunosuppression in solid organ transplant recipients has been considered a risk for developing opportunistic infections and malignancies. Acute leukemia is a rare complication. We report a case of acute promyelocytic leukemia (APL) (FAB M3) after cadaveric renal transplant for focal segmental glomerulosclerosis in a 24-year-old woman. Her immunosuppressive therapy included tacrolimus, mycophenolate mofetil, and prednisone. Approximately 2 years after transplant, she became pancytopenic, prompting administration of filgrastim. A few doses caused a markedly increased blast count, resulting in a diagnosis of APL. She was successfully treated with all-trans-retinoic acid and arsenic trioxide. Myeloproliferative neoplasms after organ transplant or due to filgrastim are rare. PMID:27695174

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

    to know its complications since it is the more aggressive procedure morbidity and mortality. Objectives: The main objective of our study is to analyze and identify clinical complications resulting from percutaneous renal biopsy in renal transplant patients. To assess whether a patient clinical factor influencing the onset of these complications. Patients and Methods: An observational, retrospective study of all patients who underwent percutaneous renal biopsy renal graft between January 2009 and January 2012. Were analyzed: age, sex, hypertension, serum creatinine, proteinuria and hemoglobin before and after the biopsy. We defined minor complications (hemoglobin drop greater than 1 g / dl and major complications (requiring transfusion, surgery, nephrectomy, arteriography, embolization or death. The biopsy was performed by the nephrology team with ultrasound guidance and withdrawing the antiplatelet therapy. Results: The number of biopsies performed was 92. The mean age of patients was 47.9 ± 13.2 years and 70.7% were men. There were 2 major complications (2.2% and both patients had urological bleeding and sepsis, one need a transfusion. Minor complications were 14.1%. The graft loss or patient death was not observed. Conclusion: Percutaneous renal graft biopsy performed by physicians experienced nephrologists under ultrasound guidance in real time, is a low risk procedure, similar to that observed in native kidney. The careful completion of our protocol renal biopsy, optimize the risk benefit ratio of this technique.

    Cyclosporine metabolism occurs in the liver via hepatic cytochrome P-450 microsomal enzymes. Ketoconazole, an imidazole derivative, has been shown to inhibit the cytochrome P-450 enzyme system. Thirty-six renal transplant recipients receiving cyclosporine as part of a triple immunosuppressive drug regimen were started on 200 mg/day of oral ketoconazole. The dose of cyclosporine was reduced by 70% at the start of ketoconazole; this dose reduction was based on our previous experience with concomitant cyclosporine-ketoconazole therapy. Ketoconazole was started in patients who had been on cyclosporine for between 10 days and 74 months. The mean cyclosporine dose was 420 mg/day (5.9 mg/kg/day) before starting ketoconazole and 66 mg/day (0.9 mg/kg/day) one year after the addition of ketoconazole; this represents a cyclosporine dose reduction of 84.7% (P less than 0.0001). The mean trough whole-blood cyclosporine concentrations measured by HPLC, were 130 ng/mL preketoconazole and 149 ng/mL after 1 year of combination therapy. Mean serum creatinine and BUN levels were unchanged before and during ketoconazole administration, and no changes in liver function tests were noted. Cyclosporine pharmacokinetics were performed before and after at least three weeks of ketoconazole. Hourly whole-blood samples were measured by HPLC (parent cyclosporine only) and TDX (parent + metabolites). Combination therapy resulted in decreases in the maximum blood concentration and the steady-state volume of distribution divided by the fractional absorption, and increases in mean residence time and the parent-to-parent plus metabolite ratio (calculated by dividing the HPLC by the TDX value). The addition of ketoconazole to cyclosporine-treated patients resulted in a significant inhibition of cyclosporine metabolism and decrease in the dosage. There was minimal nephrotoxicity, and only four rejection episodes occurred on combined therapy. The concomitant administration of the two drugs was well

    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.

    Rhabdomyolysis contributes to 7-10% of total AKI cases. Myoglobinuria as a cause of acute renal allograft dysfunction is extremely uncommon. Renal allograft recipient on cyclosporine or tacrolimus can develop myoglobinuria in presence of other precipitating factors. Present case describes an interesting report of myoglobinuria in a patient with post transplant diabetic nephropathy mimicking acute graft rejection. Clinically myoglobinuria presenting as renal allograft dysfunction is diagnosis of exclusion and renal biopsy is extremely important in making a correct diagnosis and planning optimal management in such cases.

    Riccabona, G.; Fill, H.; Hilty, E.; Leidlmair, K.

    1986-01-01

    The relation of the functional prognosis of a kidney graft to the results of renography with radioactive hippuran (OIH-RG) was assessed in 96 patients after renal allograft transplantation in 1982. By October 1, 1984 26 of these kidneys had lost their function. The curves obtained from the gamma-camera OIH-RG are classified into six different curve patterns (curve types 1 to 6) as published earlier. For the evaluation of the long-term prognosis, the survival times of the kidneys were related to the curve types. The distribution of the curve types obtained in patients with a kidney survival longer than 144 weeks differs significantly from the curve type distribution when the kidney survival is shorter than 144 weeks. The individual survival times in the collective 26 lost kidneys show a relation to the different curve types. All kidneys with curve type 4 in the last examination before hospital discharge are lost within the first 20 weeks while curve types 1 and 2 promise a functional survival up to 144 weeks. Serum creatinine time courses and their relation to the OIH-RG curve patterns are analyzed by analyses of variance and covariance with repeated measurement. These statistical analyses reveal significant differences between the creatinine courses in the single curve types and, in addition, a significant interaction of the curve types with the creatinine courses. In curve type 1, a rapid normalization of an elevated creatinine level can be predicted, while in curve type 4 no improvement of the creatinine level and thus of kidney function can be expected at least within the five days following discharge.

    We report the prevalence of BK virus (BKV) infection before renal transplantation and the dynamics of BKV viremia from pre- to post-transplantation. We assessed 60 kidney transplanted patients from a single cohort in Italy, treated with identical immunosuppressive therapy, for BK viremia at pre-transplantation, 12 h, and three and six months post-transplantation. Polymerase chain reaction showed that the prevalence of plasma BKV replication--considered a marker of infection--was 20% in pre-transplant patients. All pre-transplant-positive patients remained positive post-transplant, whereas the majority of pre-transplant-negative patients remained negative. Viremia dynamics classification revealed three clusters of patients: Cluster A++, pre-transplant-positive patients (20%) who tested positive at least once post-transplant; Cluster B-+, pre-transplant-negative patients (28%) who tested positive at least once post-transplant; and Cluster C- -, pre-transplant-negative patients (52%) who remained negative throughout. These clusters presented significant differences related to the prevalence of substantially positive patients with high plasma viral load (>10(3) copies/mL) in cluster A, but not in donors' or grafts' characteristics. We suggest that pre-transplant viral status should be considered as an additional risk factor for post-transplant BKV replication. Therefore, pre-transplant BKV infection screening in kidney transplant patients should be performed for improving planning of personalized immunosuppressant schemes and specific post-transplant surveillance.

    To determine the outcomes of pediatric renal transplant recipients who received immunosuppression consisting of early withdrawal of corticosteroids at a single Northern California center. Protocols using minimal steroid exposure have been recently reported in adult transplant recipients with successful results. We examined the outcomes of pediatric renal transplant recipients who were managed at our center using a protocol with very early discontinuation of steroids after renal transplantation. We retrospectively studied the medical records of all renal transplant recipients followed at the Children's Hospital at the University of California, Davis Medical Center from 01/2004 to 12/2005. All patients were less than 18 yr of age at the time of transplantation. The immunosuppressive protocol included three tapering daily doses of methylprednisolone, together with five doses of thymoglobulin followed by maintenance therapy with tacrolimus and MMF. Eight patients with equal numbers of males and females were transplanted during this time period. There were equal numbers of Caucasians, African-Americans, Hispanics, and Asians. A total of 37.5% (3/8) of the subjects received preemptive transplantation, 25% (2/8) received peritoneal, and 37.5% (3/8) received hemodialysis before transplantation. The median (range) age at transplantation was 12.3 (3.1-16.0) year with a follow-up of 1.7 (0.9-2.8) year. At one yr post-transplantation, 57% (4/7) of patients still required anti-hypertensives. Three children required erythropoietin supplementation after transplantation. The mean delta height standard deviation score at 12 months was 0.20 +/- 0.56. There were no episodes of clinical acute rejection. One patient switched from tacrolimus to sirolimus due to biopsy-proven CAN. No patient became diabetic or required hypoglycemic agents. Surveillance biopsies showed no subclinical acute rejection in any patient. Steroid-free immunosuppression is safe in children after renal

    Full Text Available Objective. Evaluate the prevalence and outcomes of urinary tract infection (UTI among renal transplant recipients. Methods. A secondary analysis of the Nationwide Inpatient Sample 2009–2011 was conducted. Survey-weighted multivariable regression analyses were used to examine the impact of UTI on transplant complications, total charges, and length of stay. Results. A total of 1,044 renal transplant recipients, representing a population estimate of 49,862, were included in the study. UTI was most common in transplant recipients with hypertension (53% and prevalence was noted to be 28.2 and 65.9 cases per 1,000 for men and women, respectively. UTI increased the likelihood of transplant complications (182% for men, 169% for women. Total charges were 28% higher among men as compared to 22% among women with UTI. Such infection also increased the length of stay by 87% among men and 74% among women. Discussion. UTI in renal transplant recipients was associated with prolonged length of stay, total charges, and increased odds of transplant complications. Interventions to prevent UTI among such patients should be a priority area for future research and practice.

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

    Full Text Available A 30-year-old female presented shortly after cadaveric renal transplantation with respiratory distress typical of a bacterial infection. Following initial improvement, she developed progressive respiratory failure, initially felt to be secondary to cytomegalovirus infection. Two bronchoalveolar lavages were nondiagnostic, and an open lung biopsy was performed, which revealed a pulmonary alveolar proteinosis (PAP reaction and exogenous lipid pneumonia (ELP. The ELP was considered to be secondary to the use of marijuana, in the form of weed oil, that was smoked daily for over 10 years and stopped just before renal transplantation. This is the first description of both PAP and ELP following renal transplantation, and the first description of ELP related to smoking weed oil. Physicians should be aware of the different forms of marijuana available and of their potential medical complications.

    We present a unique case of acute bacterial prostatitis caused by a very rare human pathogen, Raoultella planticola, in a renal allograft recipient 3.5 months post transplantation. Only a few cases of human infection by this pathogen have been reported worldwide. The present study reports the case of a 67-year-old man who was admitted to our transplant unit 3.5 months post transplantation with fever, dysuria, suprapubic pain, symptoms and signs of acute prostatitis, and elevated markers of inflammation and prostate-specific antigen. R. planticola was isolated in the urine culture. The patient was treated with ciprofloxacin (based on the antibiogram) and had a full recovery, with satisfactory renal function. To the best of our knowledge, this is not only the first reported case of R. planticola prostatitis, but also the first report of such an infection in a solid organ transplant recipient or in a patient on immunosuppressive medication.

    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.

    This cross-sectional study aims to assess whether renal transplantation in children under the age of 6 years has an effect on the child's later behaviour and eating and whether this outcome is related to differences in the levels of stress and coping skills shown by the parents. In this small sample of 14 children aged under 8 years, renal transplantation in the pre-school age range did not have any marked adverse effect on the children's emotional or behavioural state. The children's severe eating problems dramatically improved after transplant. Long-term, early tube-feeding does not impair the development of normal feeding patterns in these children. Parental stress levels were not elevated in the post-transplant period and parents tended to use passive coping strategies to manage the chronic illness in their child. PMID:9468781

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.

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

    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.

  13. A computerized technique for evaluating renal transplant function: validation of background correction

    International Nuclear Information System (INIS)

    Using the scintillation camera and small computer a technique has been devised to correct the count rate curve over the transplant kidney for background radioactivity following IV injection of I-131 hippurate. The background correction using I-131 hippurate alone has been validated against a more precise background correction using I-131 albumin. Using kidney and bladder curves properly corrected for background radioactivity, reliable estimates of renal uptake and excretion of I-131 hippurate may be obtained using a renal transplant evaluation computer program

    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.

    In autosomal polycystic kidney disease, nephrectomy is required before transplantation if kidney volume is excessive. We evaluated the effectiveness of transcatheter arterial embolization (TAE) to obtain sufficient volume reduction for graft implantation. From March 2007 to December 2009, 25 patients with kidneys descending below the iliac crest had unilateral renal TAE associated with a postembolization syndrome protocol. Volume reduction was evaluated by CT before, 3, and 6 months after embolization. The strategy was considered a success if the temporary contraindication for renal transplantation could be withdrawn within 6 months after TAE. TAE was well tolerated and the objective was reached in 21 patients. The temporary contraindication for transplantation was withdrawn within 3 months after TAE in 9 patients and within 6 months in 12 additional patients. The mean reduction in volume was 42% at 3 months (p = 0.01) and 54% at 6 months (p = 0.001). One patient required a cyst sclerosis to reach the objective. The absence of sufficient volume reduction was due to an excessive basal renal volume, a missed accessory artery and/or renal artery revascularization. Embolization of enlarged polycystic kidneys appears to be an advantageous alternative to nephrectomy before renal transplantation.

    Renal transplantation is the treatment of choice for end-stage renal failure. Although advances in immunosuppression have led to improvements in short-term outcomes, graft survival beyond 5 to 10 years has not improved. One of the major causes of late renal allograft failure is chronic allograft nephropathy, a component of which is nephrotoxicity from the use of calcineurin inhibitors (CNIs). In addition, premature patient death is a major limitation of renal transplantation and the major causes are cancer, cardiovascular disease and infection. CNI-free immunosuppressive regimens based on mammalian target of rapamycin (mTOR) inhibitors have been trial led over the last few years and have defined the rational use of these agents. Conversion from a CNI-based to an mTOR-inhibitor-based regimen has been successful at improving renal function for a number of years after conversion, although long-term survival outcomes are still awaited. The studies suggest that the safest and most effective time to convert is between 1 and 6 months after transplant. In addition, mTOR-inhibitor-based regimens have been shown to be associated with lower rates of post-transplant malignancy and less cytomegalovirus infection, which may add further to the appeal of this approach.

    We report a 16-yr-old female who developed AN within a month after renal transplantation and its resolution after switching from tacrolimus to cyclosporine. Her initial maintenance immunosuppressive regimen after renal transplantation consisted of tacrolimus, mycophenolate, and steroid. She had 7 kg weight loss within the first month of transplant with subsequent 10, 12, 17, and 19 kg loss after three, five, seven, and nine months of transplant, respectively. Besides weight loss and disturbances in body image, the patient developed alopecia, bradycardia, and persistent secondary amenorrhea. Upon switching to cyclosporine from tacrolimus nine months after transplant, she started regaining weight with 5 kg gain within two months and 10 kg after four months. She restarted her menstrual cycle, alopecia and bradycardia resolved, and her body image disturbance improved. Here, we describe a very unusual neuropsychiatric side effect of tacrolimus and its resolution with another calcineurin inhibitor, cyclosporine, in an adolescent renal transplant recipient.

    To measure reliable glomerular filtration rate by using the representative values of transplanted renal depths, which are measured with ultrasonography. We included 54 patients (26 men, 28 women), with having both renal scintigraphy and ultrasonography after renal transplantation. We measured DFR with Gates' method using the renal depth measured by ultrasonography, and median and mean ones in each patient. We compared GFR derived from ultrasonography-measured renal depth with GFR derived from median and mean renal depths. The correlation coefficients were obtained among GFR derived from ultrasonography-measured renal depths, median and mean renal depth under linear regression analysis. We determined whether GFR derived from median or mean renal depth could substitute GFR derived from ultrasonography-measured renal depth with Bland-Altman method. We analyze the expected errors of the GFR using representative renal depth in terms of age, sex, weight, height, creatinine value, and body surface. The transplanted renal depths range from 3.20 cm to 5.96 cm. The mean value and standard deviation of renal depths measured by ultrasonography are 4.09{+-}0.65 cm in men, and 4.24{+-}0.78 cm in women. The median value of renal depths measured by ultrasonography is 4.36 cm in men and 4.14 cm in women. The GFR derived from median renal depth is more consistent with GFR derived from ultrasonography-measured renal depth than GFR derived from mean renal depth. Differences of GFR derived from median and ultrasonography-measured renal depth are not significantly different in the groups classified with creatinine value, age, sex, height, weight and body surface. When median value is adapted as a representative renal depth, we could obtain reliable GFR in transplanted kidney simply.

    The objective of this study was to determine the risk factors of postoperative acute renal failure (ARF) in orthotopic liver transplantation (OLT). We reviewed 184 consecutive OLT. Postoperative ARF was defined as a persistent rise of 50% increase or more of the S-creatinine (S-Cr). The patients were classified as early postoperative ARF (E-ARF) (first week) and late postoperative ARF (L-ARF) (second to fourth week). Preoperative variables were age, sex, comorbidity, indication for OLT, Child-Pugh stage, united network for organ sharing status, analysis of the blood and urine, and donor's data. Intraoperative variables were systolic arterial pressure, mean arterial pressure, pulmonary capillary wedge pressure, cardiac index, and systemic vascular resistance index. Surgical technique, number of blood products transfused, need for adrenergic agonist drugs, and intraoperative complications were also important. Postoperative variables were duration of stay in the intensive care unit, time on mechanic ventilation, liver graft dysfunction, need for adrenergic agonist drugs, units of blood products infused, episodes of acute rejection, re-operations, and bacterial infections. Firstly we carried out a univariate statistical analysis, and secondly a logistic regression analysis. The risk factors for E-ARF were: pretransplant ARF (odds ratio (OR)=10.2, P=0.025), S-albumin (OR=0.3, P=0.001), duration of treatment with dopamine (OR=1.6, P=0.001), and grade II-IV dysfunction of the liver graft (OR=5.6, P=0.002). The risk factors for L-ARF were: re-operation (OR=3.1, P=0.013) and bacterial infection (OR=2.9, P=0.017). The development of E-ARF is influenced by preoperative factors such as ARF and hypoalbuminemia, as well as postoperative factors such as liver dysfunction and prolonged treatment with dopamine. The predicting factors of L-ARF differ from E-ARF and correspond to postoperative causes such as bacterial infection and surgical re-operation.

    Within the past year at our transplant center we have had the experience of performing renal allografts in two patients older than 65 years, each of whom had been on hemodialysis more than 10 years. Both resulted in patient mortality within 90 days of transplant (one due to myocardial infarction, the other due to visceral ischemia with infarction). This prompted us to review retrospectively our own data (n = 204) and the national (UNOS) data (n = 10,971) regarding transplant outcome, patient age, and length of time on dialysis prior to renal transplantation. This review revealed that patient mortality after transplant increased with the length of end-stage renal disease (dialysis, regardless of type) independent of age, the greatest mortality occurring within the first 6 months of transplant (and not thereafter); graft survival was similar for all age cohorts analyzed. Our review of the literature reveals a paucity of articles pertaining to post-transplant mortality and length of time on dialysis prior to transplant. Our results indicate the following possible conclusions. (1) The length of time of end-stage renal disease therapy prior to renal transplantation is a significant and independent risk factor for post-transplant mortality. (2) Higher priority should be given to this factor when formulating strategies for allocation of scarce resources. (3) Patients on dialysis for extended periods of time who are elderly may be at particularly high risk. (4) Patients being considered for renal transplant should be informed of their individual risk factors for mortality post-transplant based on length of ESRD therapy. (5) Renal transplantation should be considered as early as possible in patients with ESRD (or imminent ESRD). PMID:14621760

    Maintenance of healthy endothelium is essential to vascular homeostasis, and preservation of endothelial cell function is critical for transplant allograft function. Damage of microvascular endothelial cells is now regarded as a characteristic feature of acute vascular rejection and chronic allograft nephropathy, which is an important predictor of graft loss and is often associated with transplant vasculopathy. In this review, we will discuss the role of microvascular endothelium, in renal allograft dysfunction, particularly as it relates to markers of endothelial dysfunction and endothelial repair mechanisms. We also discuss the potential for therapies targeting endothelial dysfunction and transplant graft vasculopathy.

    Tacrolimus and cyclosporine are the major immunosuppressants for renal transplantation. Several studies have compared these 2 drugs, but the outcomes were not consistent. The aim of this study was to evaluate the efficacy, safety, and pharmacoeconomics of cyclosporine and tacrolimus in the treatment of renal transplantation and provide evidence for the selection of essential drugs. Trials were identified through a computerized literature search of PubMed, EMBASE, Cochrane Controlled Trials Register, Cochrane Renal Group Specialized Register of randomized controlled trials, and Chinese Biomedical database. Two independent reviewers assessed trials for eligibility and quality and then extracted data. Data were extracted for patient and graft mortality, acute rejection, and adverse events. Dichotomous outcomes were reported as relative risk with 95% confidence intervals. A decision tree model was populated with data from a literature review and used to estimate costs and quality-adjusted life years gained and incremental cost-effectiveness. Altogether, 6137 patients from 27 randomized controlled trials were included. The results of our analysis were that tacrolimus reduced the risks after renal transplantation of patient mortality, graft loss, acute rejection, and hypercholesterolemia. Nevertheless, tacrolimus increased the risk of new-onset diabetes. Pharmacoeconomic analysis showed that tacrolimus represented a more cost-effective treatment than does cyclosporine for the prevention of adverse events following renal transplant. Tacrolimus is an effective and safe immunosuppressive agent and it may be more cost-effective than cyclosporine for the primary prevention of graft rejection in renal transplant recipients. However, new-onset diabetes should be closely monitored during the medication period. PMID:25299636

    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.

    2012-01-26

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

    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.

    Aim:Spermatogonial stem cells can initiate the process of cellular differentia-tion to generate mature spermatozoa, but whether it possess the characteristic of pluripotency and plasticity, similar to embryonic stem cells, has not been elucidated. This study was designed to evaluate the differentiation potential of spermatogonial stem cells into renal cells in vivo. Methods: Neonatal mouse spermatogonial stem cells were transplanted into mature male mice lacking en-dogenous spermatogenesis. The restoration of fertility in recipient males was observed. Spermatogonial stem cells were then injected into renal parenchyma of mature female mice to make a new extracellular environment for differentia-tion. Fluorescence in situ hybridization technology (FISH) was used to detect the expression of chromosome Y in recipient renal tissues. To determine the type of cells differentiated from spermatogonial stem cells, the expression of ricinus communis agglutinin, vimentin, CD45, and F4/80 proteins were examined in the renal tissues by immunohistochemistry. Results: The proliferation of seminiferous epithelial cells was distinctly observed in seminiferous tubules of transplanted testes, whereas no regeneration of spermatogenesis was observed in non-transplanted control testes. In transplanted female renal tissues, FISH showed a much stronger immuno-fluorescence signal of chromosome Y in the nucleolus of epithelial cells of the renal tubule and podocytes of the glomerulus. Conclusion: The spermatogonial stem cells were successfully purified from mouse testicles. This finding demonstrated that spermatogonial stem cells could not only restore damaged spermatogenesis, but were also capable of differentiat-ing into mature renal parenchyma cells in vivo.

    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.

    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

    The aim of this retrospective study was to investigate the results of kidney transplantation in patients with renal amyloidosis. We analyzed the results of renal transplantation in 13 amyloidotic transplant recipients compared with those in a control group of 13 nonamyloidotic patients. While the etiology of amyloidosis was rheumatoid arthritis in one patient, in all of the others it was secondary to familial Mediterranean fever. Acute rejection episodes developed once in six and twice in one patient. The renal function in these patients was improved by antirejection treatment. Chronic rejection did not develop in any patient. However six patients (46%) died due to various complications despite functional grafts. The others are still being followed with well-functioning grafts. Among the control group, acute and chronic rejection were diagnosed in three and two patients, respectively: one patient returned to hemodialysis after 26 months of transplantation, while the others are still alive with functional grafts. There was no death in the control group. The 5- and 10-year actuarial patient survival rates of the amyloidosis and control groups were 52.2%, 26.6%, and 100%, 100%, respectively (P = .002). However, the graft survivals of the amyloidosis versus control groups were 100%, 100%, versus 87.5%, 87.5, respectively (P = .47). In conclusion, we observed a high rate of early mortality among recipients with amyloidosis associated with infectious complications. Moreover, patient survivals were lower among amyloidotic renal recipients. PMID:16549141

    Full Text Available To estimate the costs and effectiveness measured in quality-adjusted life years (QALY of kidney transplantation compared with dialysis in adults suffering from end-stage renal disease from the perspective of the Colombian healthcare system, we designed a Markov model with monthly cycles over a five-year time horizon and eight transitional states, including death as an absorbing state. Transition probabilities were obtained from international registries, costs from different local sources [case studies, official tariffs (ISS 2001 + 35% for procedures and SISMED for medications]. Data were validated by an expert panel and we performed univariate, multivariate and probabilistic sensitivity analyses. Effectiveness indicators were months of life gained, months of dialysis averted and deaths prevented. The annual discount rate was 3% and the cost-utility threshold (willingness to pay was three times gross domestic product (GDP = USD 20,000 per QALY. The costs were adopted in US dollars (USD using the 2012 average exchange rate (1 USD = COP$ 1798. The discounted average total cost for five years was USD 76,718 for transplantation and USD 76,891 for dialysis, with utilities 2.98 and 2.10 QALY, respectively. Additionally, renal transplantation represented 6.9 months gained, 35 months in dialysis averted per patient and one death averted for each of the five patients transplanted in five years. We conclude that renal transplantation improves the overall survival rates and quality of life and is a cost-saving alternative compared with dialysis.

    Inequalities between genders in access to transplantation have been demonstrated. We aimed to validate this gender inequality in a large pediatric population and to investigate its causes. This cohort study included 6454 patients starting renal replacement therapy before 18 years old, in 35 countries participating in the European Society for Paediatric Nephrology/European Renal Association-European Dialysis and Transplant Association Registry. We used cumulative incidence competing risk and proportional hazards frailty models to study the time to receive a transplant and hierarchical logistic regression to investigate access to preemptive transplantation. Girls had a slower access to renal transplantation because of a 23% lower probability of receiving preemptive transplantation. We found a longer follow-up time before renal replacement therapy in boys compared with girls despite a similar estimated glomerular filtration rate at first appointment. Girls tend to progress faster toward end-stage renal disease than boys, which may contribute to a shorter time available for pretransplantation workup. Overall, medical factors explained only 70% of the gender difference. In Europe, girls have less access to preemptive transplantation for reasons that are only partially related to medical factors. Nonmedical factors such as patient motivation and parent and physician attitudes toward transplantation and organ donation may contribute to this inequality. Our study should raise awareness for the management of girls with renal diseases. PMID:26783738

    1994-01-01

    Patients on cyclosporin A (CsA) often develop hyperuricaemia and gout. In transplant patients the use of uricosuric drugs for treating hyperuricaemia may be preferable to allopurinol because of the known interaction of the latter with azathioprine. We therefore prospectively studied the uricosuric efficacy of 100 mg benzbromarone (Bbr;Desuric) daily in 25 CsA-treated renal transplant patients with stable graft function and hyperuricaemia (> 359 mumol/l for females, > 491 mumol/l for males). Benzbromarone decreased plasma uric acid from 579 + 18 mumol/l to 313 +/- 24 mumol/l (mean +/- SEM; P 25 ml/min. Due to its excellent efficacy and lack of significant side-effects, benzbromarone appears to be preferable to allopurinol in CsA-treated renal transplant recipients with a creatinine clearance over 25 ml/min.

    Full Text Available Viral infections in renal transplant patients are an important cause of morbidity and mortality. In most cases, the clinical presentation of herpes zoster allows the diagnosis to be made only by history and physical examination. However, patients who are immunosuppressed may have uncommon presentations, and require a high index of suspicion and additional diagnostic testing for proper management. We report a rare presentation of herpes zoster duplex bilateralis involving symmetrical dermatomes over the lower limbs occurring in a woman with a recent history of renal transplantation. The skin lesions were also atypical representing a diagnostic challenge. This infection should be part of differential diagnosis of cutaneous manifestations in organ transplant recipients.

    Full Text Available South Asian renal transplant recipients have a higher incidence of cardiovascular disease compared with Caucasian renal transplant recipients. We carried out a study to determine whether paraoxonase 1, a novel biomarker for cardiovascular risk, was decreased in South Asian compared with Caucasian renal transplant recipients. Subjects were matched two to one on the basis of age and sex for a total of 129 subjects. Paraoxonase 1 was measured by mass, arylesterase activity, and two-substrate phenotype assay. Comparisons were made by using a matched design. The frequency of PON1 QQ, QR and RR phenotype was 56%, 37%, and 7% for Caucasian subjects versus 35%, 44%, and 21% for South Asian subjects (χ2=7.72, P=0.02. PON1 mass and arylesterase activity were not significantly different between South Asian and Caucasian subjects. PON1 mass was significantly associated with PON1 phenotype (P=0.0001, HDL cholesterol (P=0.009, LDL cholesterol (P=0.02, and diabetes status (P<0.05. Arylesterase activity was only associated with HDL cholesterol (P=0.003. Thus the frequency of the PON1 RR phenotype was higher and that of the QQ phenotype was lower in South Asian versus Caucasian renal transplant recipients. However, ethnicity was not a significant factor as a determinant of PON1 mass or arylesterase activity, with or without analysis including PON1 phenotype. The two-substrate method for determining PON1 phenotype may be of value for future studies of cardiovascular complications in renal transplant recipients.

    Full Text Available Viral hepatitis, especially "C" type (HCV, is an important cause of morbidity and mortality among recipients of renal transplants. In a retrospective long-term study, we reviewed 399 renal transplant patients (133F, 266M who received 415 kidneys during the past eight-years. We evaluated their HCV infection and liver status. Stored sera (frozen at 80 C as well as fresh sera collected at the time of transplant and/or at the last observation were used. The donors were cadavers in 386 and living related in 29 renal transplants. The mean follow-up period was 74 months (range 24-124 months. At the time of transplantation 105 recipients (26% were HCV positive. A the last follow-up 105 (26% recipients remained positive, 12 (2.8% seroconverted from negative to positive due to graft and/or blood transfusion and 277 remained negative. Liver biopsy was obtained from 71 to 117 (60.6% HCV +ve patients. Liver biopsy showed normal histology in 57 (80% patients, chronic active hepatitis in 42 (59% patients according to scoring of Knodle′s classification. Recurrence of glomerulonephritis in renal allografts occurred in 21 patients. Membrano proliferative glomerulonephritis ( PGN occurred in nine patients; seven (78% of them were HCV +ve compared to 29% HCV +ve in the whole group (117/399 (P< 0.001. The actuarial patient and graft survival was similar in HCV-ve and HCV +ve patients. We conclude that HCV is an important cause of liver disease in renal allograft recipients, it might be the cause of recurrence of MPGN, however, it affects neither patients nor graft survival.

    To determine the inter-patient variability of apparent diffusion coefficients (ADC) and concurrent micro-circulation contributions from diffusion-weighted MR imaging (DW-MRI) in renal allografts early after transplantation, and to obtain initial information on whether these measures are altered in histologically proven acute allograft rejection (AR). DW-MRI was performed in 15 renal allograft recipients 5-19 days after transplantation. Four patients presented with AR and one with acute tubular necrosis (ATN). Total ADC (ADC{sub T}) was determined, which includes diffusion and micro-circulation contributions. Furthermore, diffusion and micro-circulation contributions were separated, yielding the ''perfusion fraction'' (F{sub P}), and ''perfusion-free'' diffusion (ADC{sub D}). Diffusion parameters in the ten allografts with stable function early after transplantation demonstrated low variabilities. Values for ADC{sub T} and ADC{sub D} were (x 10{sup -5} mm{sup 2}/s) 228 {+-} 14 and 203 {+-} 9, respectively, in cortex and 226 {+-} 16 and 199 {+-} 9, respectively, in medulla. F{sub P} values were 18 {+-} 5% in cortex and 19 {+-} 5% in medulla. F{sub P} values were strongly reduced to less than 12% in cortex and medulla of renal transplants with AR and ATN. F{sub P} values correlated with creatinine clearance. DW-MRI allows reliable determination of diffusion and micro-circulation contributions in renal allografts shortly after transplantation; deviations in AR indicate potential clinical utility of this method to non-invasively monitor derangements in renal allografts.

    Full Text Available Experimental models of organ transplantation played a crucial role to establish the principles of transplantation immunology. The renal transplantation in rodents became the most used model to study the mechanisms of allograft rejection. To perform it, it is necessary to master the microsurgery techniques and the research group should cooperate with other specialists in the field. In this article we review the surgical techniques employed in rats, and we draw guidelines to establish studies about transplantation immunology.Os princípios da imunologia do transplante estabeleceram-se após o surgimento de modelos experimentais. Esses modelos foram fundamentais para descoberta de mecanismos de tolerância imunológica e as bases genéticas da reação de rejeição. Transplante renal em roedores utilizando técnicas de microcirurgia tornou-se o modelo ideal, e abriu um novo horizonte para condução de pesquisas sobre imunologia e fisiologia de transplantes. Neste artigo revisamos as técnicas de transplante renal, e esboçamos diretrizes para elaboração de estudos imunológicos em modelos de rejeição.

    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.

    Full Text Available Background: Long term use of immunosuppressive therapy in transplant recipients in order to prevent acute and chronic rejection increases the long term risk of cancer. This study evaluates the incidence of different organs’ cancer after renal transplantation and immunosuppressive therapy. Methods: This is a retrospective analysis of malignant tumors in renal graft recipients with more than one year graft survival. Patients were assessed according to their age, sex, diagnosis of cancer, immunosuppressive drugs, donors and period of dialysis before transplantation. Results: Evaluating all existing files in selected private clinics in Isfahan 350 patients were reviewed and 289 of them had entrance criteria. A total of 186 men and 103 women (mean age: 42.17±13.09 years were included. They were followed up over a mean period of 52.46±33.24 months. A total of six cases (2.1% of cancer were diagnosed in six recipients: All patients with cancer were male with a mean age of 51.17±14.7 years (range: 26-68 years. Tumor presented at a mean time of 51 months (rang: 15-82 months after transplantation. There were two patients with BCC, two patients with SCC and two patients with lymphoma. Two patients died of progressive malignant disease. Age, period of dialysis before transplantation, and using immunosuppressive and anti-rejection drugs had no significant impact on development of post transplant malignancy. Conclusion: The frequency of tumors in these patients is lower than what reported by other centers, probably due to short period of follow up and low incidence of cancer in our general population. The risk of malignancy was 28 fold higher among transplant recipients than in general population. High risk of cancer in this group, confirms the necessity of routine examination for organ transplant recipients both before and after transplantation.

    It is currently estimated that about 0.5% of patients will develop Kaposi's sarcoma (KS) after kidney transplantation. Tapering of immunosuppression often leads to KS remission, but also results in graft loss in more than 50% of cases. Whether retransplantation is safe in these patients is unknown. We here report on eight patients who developed KS recurrence after kidney transplantation-(A) Patients with previously treated KS: There were 4 patients who had clinical remission of KS (including three posttransplantation) for periods ranging from 5 months up to 19 years before transplantation. All 4 developed KS recurrence within months after transplantation. In 3 patients, KS regressed only when all immunosuppression was discontinued, at the price of allograft removal. Partial remission occurred in the fourth patient following reduction of immunosuppression and gancyclovir administration; (B) Patients with recurrent KS during a single transplant: 4 patients developed KS after transplantation that regressed following reduction of immunosuppressive therapy. Increased immunosuppression, in the form of steroid pulses in 3 patients was associated with recurrence of KS. Subsequent reduction of immunosuppression caused regression of KS in all 4 patients, but 2 recipients lost their allografts. These data emphasize the high risk of recurrence of KS after renal transplantation. If physicians decide to transplant patients with a history of KS, they should inform the future recipient of the possibility of KS recurrence. PMID:8781611

    The mTOR pathway has a central role in the regulation of cell metabolism, growth and proliferation. Studies involving selective gene targeting of mTOR complexes (mTORC1 and mTORC2) in renal cell populations and/or pharmacologic mTOR inhibition have revealed important roles of mTOR in podocyte homeostasis and tubular transport. Important advances have also been made in understanding the role of mTOR in renal injury, polycystic kidney disease and glomerular diseases, including diabetic nephropathy. Novel insights into the roles of mTORC1 and mTORC2 in the regulation of immune cell homeostasis and function are helping to improve understanding of the complex effects of mTOR targeting on immune responses, including those that impact both de novo renal disease and renal allograft outcomes. Extensive experience in clinical renal transplantation has resulted in successful conversion of patients from calcineurin inhibitors to mTOR inhibitors at various times post-transplantation, with excellent long-term graft function. Widespread use of this practice has, however, been limited owing to mTOR-inhibitor- related toxicities. Unique attributes of mTOR inhibitors include reduced rates of squamous cell carcinoma and cytomegalovirus infection compared to other regimens. As understanding of the mechanisms by which mTORC1 and mTORC2 drive the pathogenesis of renal disease progresses, clinical studies of mTOR pathway targeting will enable testing of evolving hypotheses.

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

    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.

    Full Text Available Much attention has been placed recently in transplantation in highly HLA-sensitized patients. In attempts to remove these antibodies and enable successful renal transplantation, several approaches have been developed. Intravenous immunoglobulin (IVIG was found to be effective in the treatment of autoimmune and inflammatory disorders (e. g. Kawasaki disease, Guillain-Barre syndrome. Recently, a beneficial effect of IVIG on the reduc- tion of anti-HLA antibodies was described. The anti-inflammatory effect of IVIG provides hopeful opportunities in antibody-mediated rejection (AMR management. There are several protocols of IVIG administration for pre-transplant desensitization and AMR treatment: high-dose IVIG, low-dose IVIG + plasmapheresis, IVIG + plasmapheresis + rituximab. These advancements have enabled transplantation in patients previously considered untransplantable and in concert with new diagnostic techniques has resulted in new approaches to management of AMR.

    Kidney transplant is the final treatment for patients with end-stage renal disease. Urinary leakage is the most-common surgical complication early after transplant. Another complication in the early posttransplant period is segmental allograft infarction. We report a kidney recipient who developed urinary leakage secondary to a segmental infarction of the upper pole of the transplanted kidney 2 months after transplant. The patient was treated successfully by a partial nephrectomy of the infracted upper lobe of the kidney. Three months after the partial nephrectomy of the allograft, serum blood urea nitrogen and creatinine were normal, and the patient was able to partake in her daily activities. Partial nephrectomy in the context of infarction of a kidney allograft is safe and can be used in similar cases.

    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

    Various studies have demonstrated that the five-year graft survival of adolescents after renal transplantation is significantly lower than in children. This may be due to poor adherence to the post-transplant regime in adolescents. It has been shown that nurses can provide support to renal transplanted adolescents with positive effects on their adherence. The aim of this descriptive cross-sectional study was to gain knowledge about important topics of nurses' support to adolescent renal transplant patients. Twenty-seven adolescents between the ages of 12 and 18 years were interviewed and given a questionnaire based on a focus group discussion. Each of the provided 43 topics was rated on its importance. Results showed that responses corresponding to the judgment "very important" ranged from 20 % to 100 %. Information about illness and therapy was given highest priority, followed by the provision of support services as well as information and the support of planning and managing the personal way of living. These topics can be seen as a set of relevant variables that may be used for focused assessment, and for planning of nursing interventions. With regard to clinical practice it is necessary to develop nursing strategies and patient and family education programs based on the results of this study. PMID:19496030

    Full Text Available Paola Salis, Chiara Caccamo, Roberto Verzaro, Salvatore Gruttadauria, Mary ArteroDivision of Nephrology and Division of Abdominal Transplantation, Istituto Mediterraneo per i Trapianti e Terapie ad Alta Specializzazione, Palermo, ItalyAbstract: Basiliximab is a chimeric mouse-human monoclonal antibody directed against the alpha chain of the interleukin-2 (IL-2 receptor on activated T lymphocytes. It was shown in phase III trials to reduce the number and severity of acute rejection episodes in the first year following renal transplantation in adults and children, with a reasonable cost-benefit ratio. The drug does not increase the incidence of opportunistic infections or malignancies above baseline in patients treated with conventional calcineurin inhibitor-based immunosuppression. In the field of renal transplantation, basiliximab does not increase kidney or patient survival, despite the reduction in the number of rejection episodes. Basiliximab may reduce the incidence of delayed graft function. In comparison with lymphocyte-depleting antibodies basiliximab appears to have equal efficacy in standard immunological risk patients. Recently, IL-2 receptor monoclonal antibodies have been used with the objective of reducing or eliminating the more toxic elements of the standard immunosuppression protocol. Several trials have incorporated basiliximab in protocols designed to avoid or withdraw rapidly corticosteroids, as well as protocols which substitute target-of-rapamycin (TOR inhibitors for calcineurin inhibitors.Keywords: basiliximab, renal transplantation, IL-2 receptor antagonists, induction, immunosuppression, corticosteroids, calcineurin inhibitors

    2009-01-01

    Full Text Available Anomalous origin of the right coronary artery (AORCA is a rare congenital anomaly with an incidence of 0.92% during routine cardiac catheterization. Its presence raises an important concern to the anaesthesiologist because it can lead on to myocardial ischaemia manifesting as either angina pectoris or myocardial infarction, or sudden death in young patients with minimal exertion, even in the absence of atherosclerosis. Patients with AORCA may be intolerant to stress and the high cardiac output condition owing to volume loading. Such a therapeutic manoeuvre may be desirable during renal transplantation to enable better perfusion of the renal graft immediately after grafting the kidney, in order to improve its function. Hence, haemodynamic goals in renal transplant recipient with AORCA can be contradictory during surgery, thereby rendering anaesthetic management challenging. We report a case of acute myocardial ischemia precipitated by fluid loading conditions in a patient with AORCA during renal transplant that was successfully treated with emergent intra-aortic balloon pump therapy intraoperatively. Judicious intraoperative fluid replacement is recommended, and volume overload must be avoided in AORCA patients undergoing surgery.

    Collecting pertinent information is first step in assessing the use of living-related kidneys for transplantation. Current bioethics legislation in France limits kidney donation to first-degree family members and spouses in emergency situations. Severe penalties are inflicted for use of other donors or sale of organs. Further valuable information can be obtained from reports in the literature on complications in donors and on the advantages of living donor organs. The proportion of live donors in France is small (3.5% from 1984 through 1993) indicating that transplantation teams prefer cadaver organs except in pediatric cases. The proportion of live donor organs transplanted in northern Europe and North America is much higher. A quick survey of French teams show that opinions and practices vary. Questions still under debate include how to guarantee freedom to refuse or accept, a freedom directly related to correct information. Several propositions have been made in an attempt to harmonize management. First, an information sheet could be distributed during the early discussions, outlining the advantages and disadvantages of live organ donation. A list of complementary examinations could also be established to identify possible contraindications for nephrectomy and define exclusion criteria. A similar procedure adopted by all transplantation teams could be based on these propositions presented in the appendix. Potential donors could then benefit from uniform protection. PMID:8685149

    The hereditary amyloid neuropathy (HAN) is characterized by a progressive sensory-motor poly-neuropathy and a dysautonomia with myocardium sympathetic denervation. This is established by MIBL scintigraphy and may enhance the troubles of conduction and of cardiac rhythm. The amyloid deposits are constituted of anomalous pre-albumin fabricated by liver. The hepatic transplant (HT) is the only known treatment. Four patients (GI: 39 {+-} 5 years) have been studied by MIBG scintigraphy, 2.2 {+-} 0.7 years after HT, and compared with 12 patients (GII: 39 {+-} 12 years) studied before HT. The left ventricular function, the coronary arteries and the at-rest scintigraphy with thallium were normal for all of them. The cardiac capture of MIBG, evaluated by the cardio-mediastinal activity ratio (C/M), measured on an anterior thoracic planar acquisition performed 4 hours after the intravenous injection of 300 MBq, was higher for GI than for GII (1.49 {+-} 0.12 vs 1.29 {+-} 0.13, p 0.02). The washouts (4 h / 20 min) were not different. In tomography, the patients of GI presented focal anomalies with a more-or-less extended apical defect, a satisfying fixation of the basal half of the anterior wall, more-or-less overflowing the septal and lateral walls, and for 2 patients, a satisfying inferior fixation. On the contrary, 9/12 patients of GII have had a diffuse absence of fixation, the other three heaving a satisfying antero-basal fixation ({chi}{sup 2}, p = 0.05). The results are not explained by difference of severity or evolution duration of HAN. Thus, it appears that there exists a sympathetic re-innervation of myocardium after HT in the HAN, debuting by the heart base, similarly with the effect of anatomic interruption of innervation in cardiac transplants

Mycophenolic acid (MPA blocks the key enzyme inosine monophosphate dehydrogenase and the production of guanosine nucleotides required for DNA synthesis. Two MPA formulations are currently used in clinical transplantation as part of the maintenance immunosuppressive regimen. Mycophenolate mofetil (MMF was the first MPA agent to be approved for the prevention of acute rejection following renal transplantation, in combination with cyclosporine and steroids. Enteric-coated mycophenolate sodium (EC-MPS is an alternative MPA formulation available in clinical transplantation. In this review, we will discuss the clinical trials that have evaluated the efficacy and safety of MPA in adult kidney transplantation for the prevention of acute rejection and their use in new combination regimens aiming at minimizing calcineurin inhibitor toxicity and chronic allograft nephropathy. We will also discuss MPA pharmacokinetics and the rationale for therapeutic drug monitoring in optimizing the balance between efficacy and safety in individual patients.Keywords: kidney transplantation, immunosuppression, mycophenolic acid, mycophenolate mofetil, enteric-coated mycophenolate sodium, acute rejection, chronic allograft nephropathy

    Kidney transplantation from living donors is widely performed all over the world. Living nephrectomy for transplantation has no direct advantages for the donor other than increased self-esteem, but it at least remains an extremely safe procedure, with a worldwide overall mortality of 0.03%. This theoretical risk for the donor seems to be justified by the socioeconomic advantages and increased quality of life of the recipient, especially in selected cases, such as pediatric patients, when living donor kidney transplantation can be performed in a preuremic phase, avoiding the psychological and physical stress of dialysis, which in children is not well tolerated and cannot prevent retarded growth. According to the Ethical Council of the Transplantation Society, commercialism must be effectively prevented, not only for ethical but also medical reasons. The risks are too high, not only for the donors, but also for the recipients, as a consequence of poor donor screening and evaluation with consequent transmission of human immunodeficiency virus (HIV) or other infective agents, as well as of inappropriate medical and surgical management of donors and also recipients, who are often discharged too early. Most public or private insurance companies consider kidney donation a safe procedure without long-term impairment and therefore do not increase the premium, whereas recipient insurance of course should cover hospital fees for the donors. "Rewarded gifting" or other financial incentives to compensate for the inconvenience and loss of income related to the donation are not advisable, at least in our opinion. Our Center does not perform anonymous living organ donation or "cross-over" transplantation. PMID:17692612

    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.

    MPA is an immunosuppressive agent used to prevent graft rejection after renal transplantation. MPA shows considerable inter- and intraindividual variability in exposure in children and has a defined therapeutic window, and TDM is applied to individualize therapy. We aimed to study the exposure to MPA measured as the AUC in pediatric renal transplant patients, to identify factors influencing exposure and to assess target attainment. Children transplanted between 1998 and 2014 in a single center were included. Two groups were identified: Group 1 (AUC 18 months post-transplantation). Therapeutic targets were set at: AUC0-12h of 30-60 mg h/L. A total of 39 children were included in Group 1 (median age 13.3 yr) vs. 14 in Group 2 (median age 13.4 yr). AUC0-12h was 29.7 mg h/L in Group 1 and 56.6 mg h/L in Group 2, despite a lower dosage in Group 2 (584 and 426 mg/m(2) , respectively). About 46% of patients reached the target AUC0-12h in Group 1. Time since transplantation and serum creatinine were significantly associated with MPA exposure (p explaining 36% of the variability. Individualization of the mycophenolate dose by more intense and more early TDM could improve target attainment. PMID:26923724

    Free radical-mediated injury releases proinflammatory cytokines and activates innate immunity. It has been suggested that the early innate response and the ischemic tissue damage play roles in the development of adaptive responses, which may lead to acute kidney rejection. Various durations of hypothermic kidney storage before transplantation add to ischemic tissue damage. The final stage of ischemic injury occurs during reperfusion that develops hours or days after the initial insult. Repair and regeneration processes occur together with cellular apoptosis, autophagy and necrosis and a favorable outcome is expected if regeneration prevails. Along the entire transplantation time course, there is a great demand for novel immune and nonimmune injury biomarkers. The use of these markers can be of great help in the monitoring of kidney injury in potential kidney donors, where acute kidney damage can be overlooked, in predicting acute transplant dysfunction during the early post-transplant periods, or in predicting chronic changes in long term followup. Numerous investigations have demonstrated that biomarkers that have the highest predictive value in acute kidney injury include NGAL, Cystatin C, KIM-1, IL-18, and L-FABP. Most investigations show that the ideal biomarker to fulfill all the needs in renal transplant has not been identified yet. Although, in many animal models, new biomarkers are emerging for predicting acute and chronic allograft damage, in human allograft analysis they are still not routinely accepted and renal biopsy still remains the gold standard.

    The relationship between the pre-transplant periodontal status and the development of post-transplant gingival overgrowth was investigated in a longitudinal study. The periodontal condition of 35 patients was examined on 2 occasions while they were on the transplant waiting list and then at 4-6, 10-12, 16 and 20 weeks post-transplant. At each visit the plaque index, the bleeding index and a pocket index (CPITN) were measured. Dental impressions were taken of the pre- and post-transplant gingival condition and used to make stone models which were used to score the gingival overgrowth index (GOI). The patients divided into 3 distinct groups having severe (n=13), mild (n=16) or no post-transplant gingival overgrowth (n=6). Only 1 of the patients had taken cyclosporin prior to inclusion into the study. All the patients who developed severe overgrowth had evidence of gingival hyperplasia before the transplant. There was no difference in the serum cyclosporin levels between the three groups (chi20.319). Furthermore, there was no statistical difference for any of the periodontal indices. This study indicates that the hyperplastic gingival inflammatory response of some individuals appears to be potentiated by cyclosporin resulting in severe post-transplant overgrowth. In other patients the same reaction may allow the fibroblastic activity to occur to an extent where it produces a mild clinically apparent overgrowth.

    Full Text Available Abstract Background Inducing donor-specific tolerance in renal transplant patients could potentially prevent allograft rejection and calcineurin inhibitor nephrotoxicity. Combined kidney and hematopoietic stem cell transplant from an HLA-matched donor is an exploratory and promising therapy to induce immune tolerance. Investigtion of molecular mechanisms involved in the disease is needed to understand the potential process of cell therapy and develop strategies to prevent this immunologic rejection. Methods We enrolled nine patients in a clinical study in which cryopreserved donor hematopoietic stem cells were infused on days 2, 4, and 6 after kidney transplantation. One month post-transplant, 4 plasma samples were collected from combined transplants (C + Tx, and 8 plasma samples from patients with kidney transplantation alone (Tx. High abundance proteins in plasma were depleted and the two-dimensional liquid chromatography-tandem mass spectrometry coupled with iTRAQ labeling was utilized to identify the protein profiling between the two groups. Clusters of up- and down-regulated protein profiles were submitted to MetaCore for the construction of transcriptional factors and regulation networks. Results and Discussion Among the 179 identified proteins, 65 proteins were found in C + Tx with at least a 2-fold change as compared with Tx. A subset of proteins related to the complement and coagulation cascade, including complement C3a,complement C5a, precrusors to fibrinogen alpha and beta chains,was significantly downregulated in C + Tx. Meanwhile, Apolipoprotein-A1(ApoA1, ApoC1, ApoA2, ApoE, and ApoB were significantly lower in Tx compared to C + Tx. Gene ontology analysis showed that the dominant processes of differentially expressed proteins were associated with the inflammatory response and positive regulation of plasma lipoprotein particle remodeling. Conclusions Thus, our study provides new insight into the molecular events in

Nonetheless, extended long-term graft outcomes have not been achieved due in part to the nephrotoxic effects of calcineurin inhibitors (CNIs and the adverse effects of steroid on cardiovascular disease risk factors. Induction therapy with lymphocyte depleting antibodies has originally been introduced into renal transplantation to provide intense immunosuppression in the early post-transplant period to prevent allograft rejection. Over the past half decade, induction therapy with both non-lymphocyte depleting (basiliximab and daclizumab and lymphocyte-depleting antibodies (antithymocyte antibodies, OKT3, alemtuzumab has increasingly been utilized in steroid or CNI sparing protocols in the early postoperative period. Alemtuzumab is a humanized monoclonal antibody targeted against CD52 on the surface of circulatory mononuclear cells. The ability of alemtuzumab (Campath-1H to

    Hemodialysis access options become complex in long-term treatment for patients with renal disease, while awaiting renal transplantation (RT). Once upper extremity sites are exhausted, lower extremities are used. RT is preferably in the contralateral iliac fossa, rarely ipsilateral. In current literature, RT dysfunction secondary to the hemodynamic effects of an ipsilateral femoral arteriovenous graft (AVG) has been rarely described. To our knowledge, AVG ligation is the only published technique for hemodynamic correction of an ipsilateral AVG. We present a simple, potentially reversible endovascular approach to manage the hemodynamic effects of an AVG, without potentially permanently losing future AVG access. PMID:26899147

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

    Objective: To evaluate the value of multislice CT angiography (MSCTA) in transplant renal artery stenosis (TRAS). Methods: Fifteen cases of TRAS underwent enhanced MSCT scanning postoperation. Multi-planar reformation (MPR), CPR (curved-planar reformation), volume rendering (VR), multi-planar volume reformation (MPVR), maximum intensity projection (MIP) and vessel probe (VP) reformation were performed to observe transplant kidney's artery. To analyse all the reconstruction technique and find the advantage and shortage of them. Results: CT findings of TRAS showed local vascular thining and enhanced renal parenchyma degradinged. CT reconstruction technique: 1 Trans-plant kidney's artery of only one case could be shown in the same MPR plane; 2 Transplant kidney's artery of 13 cases could be shown in CPR coronal and sagittal plane; 3 with 15 cases of VR, stage of courser and shape of angiostegnosis could be observed clearly through rotating the reconstruction image from different directions; 4 15 cases of MPVR could reveal transplant kidney's artery and TRAS at the same time; 5 9 cases of MIP could show TRAS in one plane; 6 15 cases of VP could show condition inside the vessel of transplant kidney, with the degree of stenosis appeared clearly. Of 15 cases of TRAS, stenosis occurred in stoma (8 cases), distant place from stoma (4 cases), stoma and distant place form stoma (2 cases), stenosis occurred in whole range (oe case). Conclusion: MSCTA has an important role as an imaging technique to evaluate TRAS of transplant kidney, which can replace DSA. It can reveal the stenosis part of vessel and direct PTA, to evaluate therapeutic effect of endovascular stent placement. MSCTA will be widespread used clinically. (authors)

    We observed a kidney transplant recipient in whom acute hepatitis was the initial manifestation of tuberculosis, preceding radiological lung involvement by several weeks. The diagnosis was suspected and treatment initiated based on the finding of a granulomatous hepatitis on liver biopsy. Mycobacterial tuberculosis was grown and identified first in liver samples and only later in sputum and bone marrow. This case illustrates the protean manifestations of tuberculosis in immunosuppressed patients. PMID:8117407

    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.

    Full Text Available We present the case of aorto-iliac aneurysm in a patient with chronic renal failure requiring dialysis who were treated with an endovascular stent graft and, later on, submitted to kidney transplantation. A 53-year-old male with renal failure requiring dialysis presented with an asymptomatic abdominal aorto-iliac aneurysm measuring 5.0cm of diameter. He was treated with endovascular repair technique, being used an endoprosthesis Excluder®. After four months, he was successfully submitted to kidney transplantation (dead donor, with anastomosis of the graft renal artery in the external iliac artery distal to the endoprosthesis. The magnetic resonance imaging, carried out 30 days after the procedure, showed a good positioning of the endoprosthesis and adequate perfusion of the renal graft.

    Antibody-mediated rejection (AMR) continues to pose a serious challenge in renal transplantation with potentially devastating consequences. Treatment options for this condition include plasmapheresis, high-dose intravenous immunoglobulin (IVIG), plasmapheresis with low-dose IVIG, and the use of rituximab (anti-CD20 chimeric antibody). We previously reported on the short-term outcome of plasmapheresis as a rescue therapy for AMR in our centre. We now report on the long-term follow up.

    Background Malignant tumor is the most common complication occurred in transplant recipients. It is widely recognized that immunosuppressive treatments increase the risk of cancer in transplant recipients. The efficacy and safety of rapamycin (RPM) in combination with low-dose calcineurin inhibitor (CNI) in treating 15 renal allograft recipients which developed urothelial carcinoma were observed. Methods Immunosuppressive regimen in all recipients was altered with rapamycin to replace mycophenolate mofetil (MMF) or azathioprine (Aza). The initial loading dosage was 2 mg/d, and the next dosage was 1 mg/d. The dosage of rapamycin was carefully adjusted according to the blood drug level and concentration of the drug was maintained at 4-6 ug/L. In all the 15 patients, the calcineurin inhibitor was reduced down to one third of the original dosage after the rapamycin blood concentration became stable. Surgical treatment and intravesical instillation chemotherapy were carried out in all patients. Recurrence of the tumor was monitored throughout the study. Post-transplant renal function and side effects were also closely monitored. Results Among the 15 patients, 9 had no tumor recurrence in 2 years, 2 had tumor recurrences twice, and 4 had once. There was no acute rejection observed during RPM treatment. Post-transplant renal function in 11 patients was improved, with a decreased creatinine level. Hyperlipoidemia and thrombocytopenia were the most frequent adverse events which responded well to corresponding treatments. Conclusion Among the renal allograft recipients with urothelial carcinoma, combination of rapamycin and low dose calcineurin inhibitor treatment is effective and safe.

    The cardiovascular and renal pathophysiology associated with chronic renal allograft rejection under triple drug immunosuppressive treatment was studied using a recently developed model (Brown Norway (BN) rats) in a 6-week experiment. Renal transplantation was performed to 10-week-old rats in a rat strain combination of Dark Agouti (DA) --> BN. The right kidney was removed from another group of BN rats (uninephrectomized). A triple drug treatment comprising cyclosporine (10 mg/kg subcutaneously, s.c.), azathioprine (2 mg/kg s.c.) and methylprednisolone (1.6 mg/kg s.c.) was given to each rat daily for 6 weeks. A control group underwent no operations nor drug treatment. After the transplantation, the systolic blood pressure in this group was increased from 116 +/- 2 to 166 +/- 2 mmHg, while in the uninephrectomized group the rise was from 115 +/- 4 to 146 +/- 4 mmHg, and no change was observed in the blood pressures of the control group. The vascular relaxation responses of mesenteric arterial rings in vitro to acetylcholine were inhibited in both the transplantation group and the uninephrectomized group as compared with the control group, but few significant differences were found in the contraction responses to noradrenaline and potassium chloride. Graft histology was examined after 6 weeks, quantified by using the chronic allograft damage index (CADI). Changes specific to a chronic rejection reaction were observed in the allografts (CADI mean 6.0) but no injuries were seen in the rats' own kidneys (CADI mean 1.2). Our findings show that allograft rejection in BN rats after renal transplantation is associated with the development of arterial hypertension. The combination of cyclosporine, methylprednisolone and azathioprine also rises blood pressure in uninephrectomized BN rats. The hypertensive effects of the drug treatment and graft rejection are associated with endothelial dysfunction.

    In 2015, 634387 million people (9% of the world's population) resided in Latin America (LA), with half of those populating Brazil and Mexico. The LA Dialysis and Transplant Registry was initiated in 1991, with the aim of collecting data on renal replacement therapy (RRT) from the 20 LA-affiliated countries. Since then, the Registry has revealed a trend of increasing prevalence and incidence of end-stage kidney disease on RRT, which is ongoing and is correlated with gross national income, life expectancy at birth, and percentage of population that is older than 65 years. In addition, the rate of kidney transplantation has increased yearly, with > 70% being performed from deceased donors. According to the numbers reported for 2013, the rates of prevalence, incidence and transplantation were (in patients per million population) 669, 149 and 19.4, respectively. Hemodialysis was the treatment of choice (90%), and 43% of the patients undergoing this treatment was located in Brazil; in contrast, peritoneal dialysis prevailed in Costa Rica, El Salvador and Guatemala. To date, the Registry remains the only source of RRT data available to healthcare authorities in many LA countries. It not only serves to promote knowledge regarding epidemiology of end-stage renal disease and the related RRT but also for training of nephrologists and renal researchers, to improve understanding and clinical application of dialysis and transplantation services. In LA, accessibility to RRT is still limited and it remains necessary to develop effective programs that will reduce risk factors, promote early diagnosis and treatment of chronic kidney disease, and strengthen transplantation programs.

    Full Text Available Hypercholesterolemia which frequently follows renal transplantation, places kidney graft recipients at an increased risk for atherosclerosis and cardiovascular diseases. We attempt in this study to determine the prevalence, and evaluate severity and treatment of hypercholesterolemia in kidney transplant recipients. We studied 78 renal transplant patients with a mean age of 42.1 years and mean transplant duration of 6.2 years (range from six months to 8.5 years. They were on triple immunosuppressive therapy and had serum creatinine level of less than 160µmol/L. Thirty-one patients (39.8% were found to have blood cholesterol levels > 6.4 mmol/L. Significant positive correlation was found between hypercholesterolemia and cyclosporine blood levels above 200 ng/ml (p< 0.0009. Furthermore, proteinuria positively correlated with hypercholesterolemia (p< 0.0006. There was no significant correlation between cholesterol blood level and the patient age, sex, presence of diabetes, prednisolone, dose, or treatment with C.-blockers and diuretics. Dietary modification was not effective in reducing the blood cholesterol level in our patients, so we used fluvastatin in a dose of 20 to 40 mg daily for a period of three months. This drug was effective in lowering the mean cholesterol blood levels from 7.1 to 5.2 mmol/L (p< 0.005. One out of 19-electromyogram studies showed abnormal pattern. We did not notice change in the levels of creatinine phosphokinase, serum creatinine or lover enzymes. In conclusion, hyper-cholesterolemia is common in stable renal transplant patients. The presence of proteinuria and the high level of blood cyclosporine are significantly associated with hypercholesterolemia. Low-dose fluvastatin was well-tolerated and effective cholesterol lowering treatment.

    2005-12-01

    Full Text Available INTRODUCTION: Short right renal vein is a frequent and well-known technical inconvenience that is commonly observed during transplantation of the right kidney. We present our experience with the elongation of short cadaveric right renal veins using the contiguous vena cava during cadaveric renal transplants. METHODS: We performed 34 kidney transplantations with a short right renal vein requiring elongation using the inferior vena cava, to make the venous anastomosis technically feasible. The elongated right renal vein was anastomosed end to side to the external iliac vein in 24 patients, to the common iliac vein in 8 patients and to the inferior vena cava in 2 patients. The right renal artery with an aortic patch was implanted end to side in 33 patients, and end to end without aortic patch to the internal iliac artery in one patient. RESULTS: In all cases, the vascular anastomoses were easily performed in the recipient and no thrombosis was observed. CONCLUSION: Elongation of a short right renal vein with the inferior vena cava is a feasible mean to overcome technical problems that may compromise the results of cadaveric renal transplantation.

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.

    Full Text Available Invasive aspergillosis is a serious complication of solid organ transplantation. An early diagnosis is hampered by the lack of reliable serum markers and, even if appropriately diagnosed and treated with current antifungal agents, has a high mortality rate. We report a case of invasive pulmonary and cerebral aspergillosis in a renal transplant patient treated with IFN-γ in conjunction with combination anti-fungal therapy for six weeks in whom complete resolution of the fungal infection was achieved. Renal function remained intact throughout the treatment period. Surveillance CT scans of the chest and head showed resolution of prior disease but revealed a new left upper lobe mass four months after completion of treatment with IFN-γ. Biopsy of the lesion was positive for primary lung adenocarcinoma, for which she underwent left upper lobe resection. The pathology report confirmed clear surgical margins and lymph nodes and no evidence of fungal hyphae. IFN-γ should be considered early in the management of invasive aspergillosis in renal transplant patients. To date, allograft rejection has not been encountered.

    Lymphomatoid granulomatosis (LYG) in renal transplant recipients is rare multisystemic angiocentric lymphoproliferative disorder with significant malignant potential. Here, we describe LYG in a 70-year-old renal allograft recipient who, 4 years after transplantation, on tacrolimus and mycophenolate mofetil and prednisone maintenance immunosuppression, complained of low-grade fever, persistent headache and gait disturbance. The MRI of the brain revealed diffuse periventricular cerebral and cerebellar contrast-enhanced lesions. The CT scan of the thorax showed multiple pulmonary nodular opacities in both lung fields. The patient was diagnosed LYG based on the cerebral biopsy showing perivascular infiltration of CD20-positive B-lymphocytes with granulomatous lesions and immunofluorescence staining with anti-EBV antibodies. With careful reduction of the immunossuppression combined with the use of rituximab, our patient showed a complete disappearance of LYG, and she is clinically well more than 4 years after the diagnosis, with good kidney function. No recurrence has been observed by radiological imaging until now. This is the first report of a durable (>4 years) complete remission of LYG after treatment with rituximab in renal transplantation.

    Full Text Available Abstract Background Tacrolimus and cyclosporine, both calcineurin inhibitors, can cause neurological side effects. While mild symptoms such as tremor are well recognised, severe complications including seizures and encephalopathy are poorly documented following renal transplantation. Case presentation We report a 42 year old man who received a cadaver renal transplant. He received tacrolimus and prednisolone. The course was uneventful for 6 weeks when he became intermittently confused, with unsteady gait and slurred speech. Following a grand mal convulsion he was admitted. He had no focal neurological signs, cerebrospinal fluid was normal; electroencephalogram was consistent with temporal lobe partial epilepsy. The magnetic resonance imaging of brain showed widespread changes with multiple areas of low signal intensity in brain stem and cerebral hemispheres. He was readmitted 3 weeks later after further fits, despite anti-convulsant therapy. He was psychotic with visual hallucinations, and rapidly became obtunded. Although his tacrolimus blood concentration had been kept in the normal range, his symptoms improved dramatically when the tacrolimus was stopped. Conclusion Severe central nervous system toxicity from calcineurin inhibitors has been rarely reported in renal transplantation and we found only one report of tacrolimus-induced toxicity in an adult. We believe the condition is frequently undiagnosed. It is a very important diagnosis not to miss as the remedy is simple and failure may result in unnecessary brain biopsy, as well as irreversible injury.

    Full Text Available Prophylaxis has dramatically decreased the occurrence of cytomegalovirus (CMV infection after renal transplantation. Optimal regimens of treatment remain controversial, especially in pediatric recipients. The aim of this study was to evaluate the effectiveness of valganciclovir (VGC versus aciclovir/valaciclovir (ACV in a pediatric renal transplant population. Data from 101 renal transplantations were retrospectively analyzed. Except those with R-/Dstatus, all patients received prophylaxis either with ACV, n = 39 or VGC, n = 38. Incidences of positive CMV antigenemia and disease, as well as the delay in relation to the prophylaxis, were collected during at least 12 months after the end of treatment. Positive CMV antigenemia was reported in 34 patients (ACV: 16, VGC: 16, no prophylaxis: 2. CMV disease occurred in 15 patients (ACV: 5; VGC: 8 (ns. For the majority of patients under VGC, positive CMV antigenemia occurred within the year following the withdrawal of prophylaxis (VGC: 14; ACV: 5, P <0.05, whereas it occurred during prophylaxis in 11 patients under ACV versus two under VGC (P <0.05. The over-all incidence of positive CMV antigenemia was similar between ACV and VGC prophylaxis. However, VGC was more efficient to prevent early CMV infection while patients treated with ACV had less CMV infection or disease after the end of the prophylaxis.

    Prophylaxis has dramatically decreased the occurrence of cytomegalovirus (CMV) infection after renal transplantation. Optimal regimens of treatment remain controversial, especially in pediatric recipients. The aim of this study was to evaluate the effectiveness of valganciclovir (VGC) versus aciclovir/valaciclovir (ACV) in a pediatric renal transplant population. Data from 101 renal transplantations were retrospectively analyzed. Except those with R-/Dstatus, all patients received prophylaxis either with ACV, n = 39 or VGC, n = 38. Incidences of positive CMV antigenemia and disease, as well as the delay in relation to the prophylaxis, were collected during at least 12 months after the end of treatment. Positive CMV antigenemia was reported in 34 patients (ACV: 16, VGC: 16, no prophylaxis: 2). CMV disease occurred in 15 patients (ACV: 5; VGC: 8) (ns). For the majority of patients under VGC, positive CMV antigenemia occurred within the year following the withdrawal of prophylaxis (VGC: 14; ACV: 5, P ACV versus two under VGC (P ACV and VGC prophylaxis. However, VGC was more efficient to prevent early CMV infection while patients treated with ACV had less CMV infection or disease after the end of the prophylaxis.

    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.

    Full Text Available Tuberculosis is one of the most frequent opportunistic infections after renal transplantation and occurred in 30 of 1264 patients transplanted between 1976 and 1996 at Hospital São Paulo - UNIFESP and Hospital Dom Silvério, Brazil. The incidence of 2.4% is five times higher than the Brazilian general population. The disease occurred between 50 days to 18 years after the transplant, and had an earlier and worse development in patients receiving azathioprine, prednisone and cyclosporine, with 35% presenting as a disseminated disease, while all patients receiving azathioprine and prednisone had exclusively pulmonary disease. Ninety percent of those patients had fever as the major initial clinical manifestation. Diagnosis was made by biopsy of the lesion (50%, positivity to M. tuberculosis in the sputum (30% and spinal cerebral fluid analysis (7%. Duration of treatment ranged from 6 to 13 months and hepatotoxicity occurred in 3 patients. The patients who died had a significant greater number of rejection episodes and received higher doses of corticosteroid. In conclusion, the administration of cyclosporine changed the clinical and histopathological pattern of tuberculosis occurring after renal transplantation.

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

    Our objective was to define optimal management of distal ureteric strictures following renal transplantation. A systematic review on PubMed identified 34 articles (385 patients). Primary endpoints were success rates and complications of specific primary and secondary treatments (following failure of primary treatment). Among primary treatments (n = 303), the open approach had 85.4% success (95% CI 72.5-93.1) and the endourological approach had 64.3% success (95% CI 58.3-69.9). Among secondary treatments (n = 82), the open approach had 93.1% success (95% CI 77.0-99.2) and the endourological approach had 75.5% success (95% CI 62.3-85.2). The most common primary open treatment was ureteric reimplantation (n = 33, 81.8% success, 95% CI 65.2-91.8). The most common primary endourological treatment was dilation (n = 133, 58.6% success, 95% CI 50.1-66.7). Fourteen complications, including death (4 weeks post-op) and graft loss (12 days post-op), followed endourological treatment. One complication followed open treatment. This is the first systematic review to examine the success rates and complications of specific treatments for distal ureteric strictures following renal transplantation. Our review indicates that open management has higher success rates and fewer complications than endourological management as a primary and secondary treatment for post-transplant distal ureteric strictures. We also outline a post-transplant ureteric stricture evaluation and treatment algorithm.

    Full Text Available Abstract Objective Our objective was to evaluate the impact of routine use of double-J stents on the incidence of urinary tract infection after renal transplantation. Methods We conducted a retrospective-comparative single-centre study in 310 consecutive adult deceased donor kidney recipients transplanted from 2002 to 2006. Patients were divided in two groups, with or without urinary stent implantation. To evaluate the predictive factors for UTI, donor and recipients pre- and post-transplantation data were analysed. Early urological complications and renal function within 12 months of transplantation were included as well. Results A total of 157 patients were enrolled to a stent (ST and 153 patients to a no-stent (NST group. The rate of urinary tract infection at three months was similar between the two groups (43.3% ST vs. 40.1% NST, p = 0.65. Of the identified pathogens Enterococcus and Escherichia coli were the most common species. In multivariate analysis neither age nor immunosuppressive agents, BMI or diabetes seemed to have influence on the rate of UTI. When compared to males, females had a significantly higher risk for UTI (54.0% vs. 33.5%. Conclusion Prophylactic stenting of the ureterovesical anastomosis does not increase the risk of urinary tract infection in the early postoperative period.

    In renal transplanted patients, lymphoceles and lymphorrhea are well-known lymphatic complications. Surgical damage of the lymphatics of the graft during the procurement and of the lymphatic around the iliac vessels of the recipients has been associated with development of lymphatic complications. However, lymphatic complications may be related to medical factors such as diabetes, obesity, blood coagulation abnormalities, anticoagulation prophylaxis, high dose of diuretics, delay in graft function and immunosuppressive drugs. Consistently, immunosuppression regimens based on the use of mTOR inhibitors, especially in association with steroids and immediately after transplantation, has been associated with a high risk to develop lymphocele or lymphorrhea. In addition, several studies have demonstrated the association between rejection episodes and lymphatic complications. However, before the discovery of reliable markers of lymphatic vessels, the pathogenic mechanisms underlining the development of lymphatic complications during rejection and the influence of mTOR inhibitors remained not fully understood. The recent findings on the lymphatic systems of either native or transplanted kidneys together with the advances achieved on lymphangiogenesis shared some lights on the pathogenesis of lymphatic complications after renal transplantation. In this review, we describe the surgical and medical causes of lymphatic complications focusing on the rejection and immunosuppressive drugs as causes of lymphatic complications. PMID:26413290

  16. Role of radiopharmaceutical renal function studies in the medical surveillance of patients with transplanted kidneys

    International Nuclear Information System (INIS)

    In a study group of 35 patients having received a total of 37 kidneys 204 renal function scintiscans were obtained following administration of 99mTc DTPA and analysed with regard to the question as to whether radiopharmaceutical investigations using a gamma camera are a useful auxiliary tool to detect and diagnose functional disorders in the transplant that occur soon after surgery. In all of 13 patients showing complications in the form of prolonged anuria or oliguria during a period of up to 14 days following surgical intervention, the renal function scintiscans either permitted as firm diagnosis to be established or revealed conclusive findings that pointed to the necessity of further specific tests. Long-term follow-up studies carried out in 33 individuals failed or were slow to reveal acute or chronic rejection processes in one quarter of the patients, whereas the renal function scintiscans gave the earliest warning of functional disorders, unfavourable developments and complications in another quarter of patients; in the remaining part, the test results were in keeping with the clinical findings. Renal function scintiscans were thus judged to be a valuable diagnostic tool to ascertain and identify disorders occurring soon after surgery as well as to detect the early signs of functional disorders in the transplant during long-term follow-up studies. In view of the fact, however, that the sensitivity of the method in this field of application only is of the order of 75%, further research work appears to be required here. (TRV)

    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.

    Full Text Available This review highlights the key messages from the KDIGO (Kidney Disease: Improving Global Outcomes clinical practice guidelines for care of kidney transplant recipients, which were written to be global guidelines irrespective of the regulatory, fiscal, cultural, socioeconomic, or geographical environment. The distillation of 3168 randomized control trials, 7543 cohort studies, and 1609 reviews led to recommendations rated by the strength of supporting evidence and the quality of the data from A to D. Despite this, the quality of the evidence is surprisingly low for the majority of decisions that are routinely taken in all transplant units throughout the world, highlighting the needs for properly designed randomized controlled trials. The principle areas covered in the guidelines include immunosuppression, management of acute rejection, monitoring of the patient and graft, chronic allograft injury, kidney biopsy, nonadherence, vaccination, infectious diseases, cardiovascular risk management, malignancy, bone disease, pediatric growth, lifestyle, fertility, and mental health. This review highlights a number of these areas for consideration focusing on the different types of evidence that we use in daily clinical practice.

    Full Text Available BACKGROUND: The average prevalence of hepatitis C virus (HCV infection in renal transplant recipients is 10%. Studies of these patients with HCV infection usually focuses on long-term graft survival and patient survival. Studies of the correlation between HCV infection and bone mineral density (BMD in renal transplant patients are limited. The aim of this study was to investigate whether HCV infection is a risk factor for BMD change during a short follow-up period. METHODS: Seventy-six renal transplant recipients underwent 2 separate dual-energy X-ray absorptiometry (DXA scans during a mean period of 14 months. Fifteen patients were HCV infection. First bone mineral density (BMD at the lumbar spine, hip, and femoral neck was determined using dual-energy X-ray absorptiometry (DXA between September 2008 and March 2009. After that, 34 patients took alendronate sodium 70 mg per week. Subgroups risk factors analysis was also performed into with or without alendronate. Immunosuppressive agents, bisphosphonates, patient characteristics, and biochemical factors were analyzed to identify associations with BMD. RESULTS: After 14 months, in 76 patients, BMD of the lumbar spine had significantly increased (from 0.9 g/cm² to 0.92 g/cm², p<0.001, whereas BMD of the hip and femoral neck had not. Multiple linear regression analysis showed that HCV infection was negatively associated with BMD change in the lumbar spine ( β: -0.247, 95% CI, -0.035 to -0.002; p = 0.028. Moreover, in subgroup analysis, among 42 patients without alendronate, multiple linear regression analysis showed HCV infection was a risk factor for adverse BMD change of the lumbar spine ( β: -0.371, 95% CI, -0.043 to -0.003; p = 0.023. CONCLUSION: HCV infection in renal transplant recipients was a negative risk factor for BMD change in the lumbar spine. Moreover, alendronate may be able to reverse the negative effect of HCV infection on bone in renal transplant recipients.

    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.

    Transplant renal artery stenosis (TRAS) is a vascular complication frequently seen because of increase in the number of renal transplantations. Early diagnosis and management is essential to optimize a proper graft function. Currently, the endovascular treatment of TRAS using angioplasty and/or stenting is considered the treatment of choice with the advantage that it does not preclude subsequent surgical correction. Treatment of TRAS with the use of stents, particularly in tortuous transplant renal anatomy presents a unique challenge to an interventional radiologist. In this study, we present three cases from our practice highlighting the use of a balloon-expandable Multi-Link RX Ultra coronary stent system (Abbott Laboratories, Abbott Park, Illinois, USA) for treating high grade focal stenosis along very tortuous renal arterial segments. Cobalt-Chromium alloy stent scaffold provides excellent radial force, whereas the flexible stent design conforms to the vessel course allowing for optimal stent alignment. PMID:26629289

    Two children, boys of 8 and 13 years, presented with measles-associated encephalopathy several years after kidney transplantation for congenital nephrotic syndrome. In the absence of prior clinical measles, the neurological symptoms initially eluded diagnosis, but retrospective analysis of stored samples facilitated the diagnosis of measles-associated encephalopathy without recourse to biopsy of deep cerebral lesions. Each had received a single dose of measles mumps and rubella vaccine before 12 months of age. Prior vaccination, reduction of immunosuppression and treatment with intravenous immunoglobulin and ribavirin may have contributed to their survival. Persistent measles virus RNA shedding, present in one child, was not controlled by treatment with i.v. ribavirin. Two years later, both patients continue to have functioning allografts with only minimal immunosuppression. These cases illustrate the difficulty in diagnosing measles-associated encephalopathy in the immunocompromised host, even in the era of molecular diagnostics, and highlight the renewed threat of neurological disease in communities with incomplete herd immunity.

    Full Text Available A 53-year-old renal allograft recipient developed nocardial cerebral abscess. It manifested clinically with encephalitis, polycythemia, convulsions, syndrome of inappropriate secretion of antidiuretic hormone (SIADH and a space-occupying lesion presenting as multiple ring shadows in the left fronto-parietal lobe on computerized tomography (CT scan of the brain. The initial clinical presentation included an afebrile patient with headache, convulsions and altered sensorium with no lateralising neurological deficit. He deteriorated later and developed coma with right hemiplegia. Purulent material was drained through left frontal craniotomy, and the culture confirmed the presence of nocardial infection. Despite aggressive therapy, the patient died a few days later. We conclude that high degree of early suspicion, diagnosis and prompt treatment should be stressed.

    Background Renal transplants can improve the quality of life for recipients, but the quality of their sexual life might not be improved. This study was conducted to research the prevalence of erectile dysfunction (ED) and the influential factors in male renal transplant recipients (RTRs).Methods A cross-sectional survey was conducted in three renal transplantation centers. Structured questionnaires were administrated by trained interviewers to 824 male renal transplant patients, who had active sexual lives in the last 6 months.Results Complaints of ED were reported by 75.5% of the 809 RTRs (age range 19-75 years, mean age (45±10) years),whose questionnaires were completed. Mild, moderate and severe ED were reported at 53.6%, 8.3% and 13.6%,respectively. The mean age and the graft duration were significantly higher in male RTRs with ED compared to potent graft recipients (P=-0.00 and 0.04, respectively). The prevalence of ED increased with the increase in age. It was 60.7%, 65.8%,75.2%, 87.5% and 92.2% in patients with age below 30 years, 31-40 years, 41-50 years, 51-60 years and over 60 years,respectively (P=0.000). Moreover, the severity of ED increased with aging. The percentage of moderate and severe cases of ED increased from 6.7% in patients below 40 years to 28.9% in those over 40 years (P=0.000). The prevalence of ED in the RTR who had no occupation was higher than in those who were holding a position (P=0.001). The prevalence of ED decreased with the increase in the education level. The prevalence of ED was 94.3%, 86.4%, 74.0% and 67.8% in men with elementary school or lower, middle school, high school, and college or higher degrees, respectively (P=0.000). Patients,whose distal end of arteria iliaca interna was interrupted and underwent iterative transplantation, worried transplanted kidney function was impacted by sexual life, and received cyclosporine (CsA)-based immunosuppressive regimens, were more likely to have ED (P=0.000, 0.001, 0.000, 0

    Many patients with hepatorenal syndrome (HRS) end up receiving a combined liver and kidney transplant (CKLT) with preservation of native kidneys, specially type 1 HRS since is characterizes by a very rapid deterioration of renal function. Eventually, most of the patients regain renal function, but it is unknown if this is due to the transplanted kidney, the recovery of native renal function, or both. The aim of this study is to evaluate if there is recovery of native renal function in patient...

    Our center has offered thymoglobulin induction with steroid minimization to our pediatric renal transplant patients for the last 10 yr. Steroid minimization or avoidance has shown favorable results in survival, kidney function, and growth in previous studies of pediatric patients. We report our experience with this protocol over the past 10 yr with respect to patient/graft survival, acute rejection episodes, renal function, linear growth, bone density, cardiovascular risk factors, and opportunistic infections. A retrospective chart review was performed for pediatric renal transplant patients on the steroid-minimized protocol between January 2002 and December 2011 on an intention to treat basis. Patient demographics, height, weight, serum creatinine, iGFR, biopsies, and survival data were collected. Height and weight z-scores were calculated with EpiInfo 7, using the CDC 2000 growth charts. Survival was calculated using Kaplan-Meier analysis. eGFR was calculated using the original and modified Schwartz equations. Forty-four pediatric patients were identified, aged 13 months to 19 yr. Five-yr survival was 95.5% for males and 94.4% for females. Only five patients had biopsy-proven ACR, two of which were at more than 12 months post-transplantation. Height delta z-scores from transplant to one, three, and five yr were 0.34, 0.38, and 0.79, respectively. Weight delta z-scores from transplant to one, three, and five yr were 0.87, 0.79, and 0.84, respectively. Mean original Schwartz eGFR was 84.3 ± 15.8 mL/min/1.73 m(2) , modified Schwartz eGFR was 59.3 ± 11.5 mL/min/1.73 m(2) , and iGFR was 64.2 ± 8.5 mL/min/1.73 m(2) at three yr. Of 18 subjects who had a bone density exam, none had a z-score less than -2 on DEXA exam at one-yr post-transplantation. Fifty-one percent of patients were on antihypertensives at the time of transplant compared with 43% at one-yr post-transplantation. Three yr post-transplantation, the average LDL was <100 mg/dL, and

    Full Text Available Pseudotumor cerebral (PC é uma síndrome, caracterizada pela presença de hipertensão intracraniana (HIC e sistema ventricular normal. Pacientes submetidos a transplante renal parecem ser mais suscetíveis a desenvolvê-la, devido à terapia com imunossupressores. Ciclosporina (CsA é uma causa rara de PC, pouco descrita na literatura e que deve ser lembrada no diagnóstico diferencial de HIC e papiledema nesses pacientes. Relatamos um caso de um menino de 10 anos, há três anos com enxerto renal, em uso crônico de micofenolato mofetil (MMF, CsA e baixas doses de prednisona que apresentou quadro de cefaleia, vômitos, diplopia e fotofobia. Fundoscopia revelou edema de papila bilateral. Exame do líquor (LCR e de imagem foram normais. Após exclusão de causas secundárias, foi feito diagnóstico de PC devido ao uso crônico de CsA, que, portanto, foi substituída por Sirolimus. O paciente apresentou melhora clínica progressiva, com resolução do papiledema após três mesesPseudotumor cerebri (PC is a syndrome characterized by the presence of intracranial hypertension (ICH and no alteration in the ventricular system. Renal transplanted patients seem more susceptible to develop it due to immunosuppressive therapy. Cyclosporin (CsA is a rare cause of PC, scarcely reported in the literature, and should be considered in the differential diagnosis of ICH and papilledema in those patients. We report the case of a 10-year-old boy, with a renal allograft for three years, on chronic use of mycophenolate mophetil (MMF, CsA, and low doses of prednisone. The patient presented with headache, vomiting, diplopia, and photophobia. Funduscopy showed bilateral papilledema. Cerebrospinal fluid analysis and imaging tests were normal. After excluding secondary causes, PC was diagnosed based on the chronic use of CsA, which was then replaced by sirolimus. After that, the patient progressively improved, and the papilledema resolved in three months

    OBJECTIVE: To quantify the dietary calcium and vitamin D intake in adult renal-transplant recipients attending at a large teaching hospital in Ireland for follow-up. SETTING: Outpatient renal-transplant follow-up clinic. SUBJECTS: Fifty-nine adult renal transplant recipients (58% male) with a mean age of 46 years, a median transplant duration of 6 years, and a mean estimated glomerular filtration rate (eGFR) of 50 mL\\/min per 1.73 m2. Fifty-three percent were at National Kidney Foundation stage 3 chronic kidney disease, and 14% had stage 4 chronic kidney disease. INTERVENTION: This cross-sectional, observational study used a tailored food frequency questionnaire specific for calcium and vitamin D intake in Irish adults, which was completed during a face-to-face interview with each subject. MAIN OUTCOME MEASURE: The main outcome measure was the average daily dietary and supplemented calcium and vitamin D intake. RESULTS: The median interquartile range (IQR) dietary calcium intake was 820 mg\\/day (range, 576-1,177 mg\\/day), and was similar in men and women (recommended intake > or = 1,000 mg\\/day in adult men and nonmenopausal adult women, > or = 1,500 mg\\/day in menopausal women). Five participants received calcium supplementation. Overall, 59% of men and 64% of women had total calcium intakes below the recommended amounts. The median IQR estimated dietary vitamin D intake was 5.2 microg\\/day (range, 2.4-6.4 microg\\/day) in women, and 4.6 microg\\/day (range, 2.2-6.6 microg\\/day) in men (recommended intake, > or = 10 microg\\/day). Six subjects received vitamin D supplementation. Total vitamin D intakes were suboptimal in 91% of men and 87% of women. Dietary calcium and vitamin D intakes significantly correlated with each other, but neither was significantly related to eGFR category, and was similarly low in both presumed menopausal women and in the initial year posttransplantation. CONCLUSION: These findings suggest that dietary and total calcium and

    Full Text Available Calcineurin-inhibitors and hepatitis C virus (HCV infection increase the risk of post-transplant diabetes mellitus. Chronic HCV infection promotes insulin resistance rather than beta-cell dysfunction. The objective was to elucidate whether a conversion from tacrolimus to cyclosporine A affects fasting and/or dynamic insulin sensitivity, insulin secretion or all in HCV-positive renal transplant recipients.In this prospective, single-center study 10 HCV-positive renal transplant recipients underwent 2h-75g-oral glucose tolerance tests before and three months after the conversion of immunosuppression from tacrolimus to cyclosporine A. Established oral glucose tolerance test-based parameters of fasting and dynamic insulin sensitivity and insulin secretion were calculated. Data are expressed as median (IQR.After conversion, both fasting and challenged glucose levels decreased significantly. This was mainly attributable to a significant amelioration of post-prandial dynamic glucose sensitivity as measured by the oral glucose sensitivity-index OGIS [422.17 (370.82-441.92 vs. 468.80 (414.27-488.57 mL/min/m2, p = 0.005, which also resulted in significant improvements of the disposition index (p = 0.017 and adaptation index (p = 0.017 as markers of overall glucose tolerance and beta-cell function.

    The cornerstone of cardiovascular risk management is lifestyle intervention including exercise which could exert favorable impact also in renal transplant recipients. Nevertheless, reliable assessment of the effect of lifestyle interventions is complicated and the available data in this population are not consistent. The aim of the study was to evaluate the effect of physical activity on selected laboratory markers of vascular health including circulating stem cells, endothelial progenitor cells, microparticles, and plasma asymmetric dimethyl arginine in renal transplant recipients. Nineteen men and 7 women were recruited in 6-month program of standardized and supervised exercise. Control group consisted of 23 men and 13 women of similar age and body mass index not included into the program. One year after the transplantation, the main difference between intervention and control group was found in the change of endothelial progenitor cells (p=0.006). Surprisingly, more favorable change was seen in the control group in which endothelial progenitor cells significantly increased compared to the intervention group. The explanation of this finding might be a chronic activation of reparative mechanisms of vascular system in the population exposed to multiple risk factors which is expressed as relatively increased number of endothelial progenitor cells. Therefore, their decrease induced by exercise might reflect stabilization of these processes.

    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.)

Revendo a literatura sobre o assunto, chegam à conclusão de que, provavelmente, com a imunodepressão medicamentosa, as lesões pulmonares por reinfecção endógena foram as primeiras a aparecer sob a forma de uma histoplasmose pulmonar crônica.The Authors report a case of disseminated histoplasmosis in a patient during the course of non related kidney transplant. Besides the fungal infection detected by serology and histopathology, autopsy showed macro and micro-nodular hepatic cirrhosis, probably of viral etiology (B virus, hepatocarcinoma, lymphoid depletion of the spleen and transplant glomerulonephritis. After concerning literature review the Authors conclude that probably due to immunosuppressive therapy, the pulmonary lesions by endogenous reinfection were the first to appear under the form of a chronic pulmonary histoplasmosis.

    Full Text Available In this study, data on post-renal transplant lymphoproliferative disorders (PTLD collected from the existing literature were pooled and analyzed to compare the characteristics, predictors and prognosis of small intestinal PTLDs. We performed a comprehensive search for the available data by Pubmed and Google scholar search engines for reports on this subject. Data from 18 previously published studies, comprising 120 renal allograft recipients, were included in the analysis. Renal transplant recipients with intestinal PTLD were significantly less likely to have Hogkin′s and Hogkin′s-like lesions (P = 0.044 and to be younger at the time of transplan-tation (P = 0.07. Except for Hodgkin′s-like lesions, histopathological evaluations elsewhere were comparable between the group with PTLD in the small intestine and age- and sex-matched renal transplant recipients with PTLD in other sites. The overall mortality was relatively higher in the control group (P = 0.09. When death only due to PTLD was used as the outcome, a trend toward better outcome was seen for the intestinal PTLD group compared with the other localizations (P = 0.1. The 1- and 5-year survival rates for intestinal PTLD patients were 57% and 37%, respectively, compared with 54% and 21%, respectively, for the control group. According to our findings based on analysis of international data, renal transplant patients with small intestinal PTLD are more likely to be of younger age but less frequently represent Hodgkin′s and Hodgkin′s-like lesions. They also have better patient survival compared with transplant recipients with PTLD in other locations. Further multi-center prospective studies are needed to confirm our results.

    Manifestations of breast abnormalities in these patients included breast calcifications, duct dilatation, fibrocystic change, rapidly enlarged multiple fibroadenomas, edema, invasive ductal cancer, extensive fibrosis, spontaneous hemorrhage, and Mondor's disease. These interesting cases we experienced are reported. Prolactin, growth hormone, and cortisol are required concurrently for normal development of mammary epithelium. Hormonal profile of chronic renal failure is different to normal person due to decreased renal clearance. The incidence of breast cancer is also increased in CRF. Metastatic soft tissue calcification is well described finding in chronic renal failure related to an increase in serum calcium phosphate product and secondary hyperparathyroidism. Kidney failure alone may increases prolactin level. The possibility of deranged hypothalamic-pituitary control mechanisms do not excluded. Impaired prolactin response to TRH stimulation has also been observed. Methyldopa and tricyclic antidepressants specifically were associated with hyperprolactinemia. Cyclosporin administration may elevate serum prolactin levels with simultaneous down regulation of prolactin receptors. Some populations of lymphocytes and fibroblasts exhibit cyclosporin receptors. Cyclosporin could potentially promote fibroadenomas by direct action, and seems to alter LH secretion.

    Background Delayed graft function (DGF) is common in kidney transplants from organ donation after cardiac death (DCD) donors.It is associated with various factors.Determination of center-specific risk factors may help to reduce the incidence of DGF and improve the transplantation results.The aim of this study is to define risk factors of DGF after renal transplantation.Methods From March 2010 to June 2012,56 cases of recipients who received DCD kidneys were selected.The subjects were divided into two groups:immediate graft function (IGF) and DGF groups.Transplantation factors of donors and recipients as well as early post-transplant results of recipients were compared between the two groups.Results On univariate analysis,preoperative dialysis time of recipients (P<0.001),type of dialysis (P=0.039),human leucocyte antigen (HLA) mismatch sites (P<0.001),the cause of brain death (P=0.027),body mass index (BMI) of donors (P<0.001),preoperative infection (P=0.002),preoperative serum creatinine of donors (P <0.001),norepinephrine used in donors (P <0.001),cardiopulmonary resuscitation (CPR) of donors (P <0.001),warm ischemia time (WIT) (P<0.001) and cold ischemia time (CIT) (P<0.001) showed significant differences.Recipients who experienced DGF had a longer hospital stay,and higher level of postoperative serum creatinine.Conclusion Multiple risk factors are associated with DGF,which had deleterious effects on the early post-transplant period.

    The outcome of renal transplantation is improved by cyclosporine and tacrolimus. However, its success is limited by drug-induced nephrotoxicity. Therefore, monitoring their levels is important. These levels are influenced mainly by CYP3A4, CYP3A5 and MDR- 1 genes. These levels also affect target molecules of CNIs, mainly IL-2. Inter-individual differences in these levels have been attributed to SNPs in these genes and hence study of these SNPs assumes significance. So far no study has been carried out on Indian renal transplant recipients covering the SNPs of the genes involved in metabolism, efflux and drug target of CNIs, hence the data is lacking for Indian population. The aim is to study A-392G SNP of CYP3A4, A6986G SNP of CYP3A5, C3435T SNP of MDR-1 and T-330G SNP of IL-2 genes and correlate with CNI blood levels. Hundred healthy subjects and 100 consecutive renal transplant recipients; 56 on CsA and 44 on tacrolimus were genotyped by PCR followed by restriction enzyme assay for mentioned SNPs. No significant difference was observed between level/dose (L/D) ratio of CNIs and CYP3A4 and IL-2 SNPs. However, median L/D ratio for tacrolimus was significantly higher in subjects with CYP3A5*3/*3 (n = 24) (P = 0.011) and MDR- 1 3435TT (n = 18) (P = 0.0122). The findings from this study show that homozygous mutant patients for CYP3A5 and MDR-1 gene SNPs could be managed with lower tacrolimus dose to avoid nephrotoxicity. PMID:21072155
