    ABO-incompatible (ABOi) kidney transplantation has long been considered a contraindication to successful kidney transplantation. During the last 25 years, increasing organ shortage enforced the development of strategies to overcome the ABO antibody barrier. In the meantime, ABOi kidney transplantation has become a routine procedure with death-censored graft survival rates comparable to the rates in compatible transplantations. Desensitization is usually achieved by apheresis and B cell-depleting therapies that are accompanied by powerful immunosuppression. Anti-A/B antibodies are aimed to be below a certain threshold at the time of ABOi kidney transplantation and during the first 2 weeks after surgery. Thereafter, even a rebound of anti-A/B antibodies does not appear to harm the kidney transplant, a phenomenon that is called accommodation, but is poorly understood. There is still concern, however, that infectious complications such as viral disease, Pneumocystis jirovecii pneumonia, and severe urinary tract infections are increased after ABOi transplantations. Recent data from the Collaborative Transplant Study show that during the first year after kidney transplantation, one additional patient death from an infectious complication occurs in 100 ABOi kidney transplant recipients. Herein, we review the recent evidence on ABOi kidney transplantation with a focus on desensitization strategies and respective outcomes. PMID:28321223

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

    Full Text Available We report the first Russian experience of successful ABO-incompatible kidney transplantation using anti-CD20 + IA + IvIg pretransplant conditioning protocol and tacrolimus + MMF + steroids as maintenance immunosuppression. IA procedures were performed on reusable columns ABO-Adsopak® (POCARD Ltd. Moscow, Russia. IA treatments following the administration of rituximab efficiently lowered the immunoglobulin M (IgM and G (IgG anti-A/B antibodies titers in all patients. The transplantation could be performed in all cases and the kidneys showed primary function. Unfortunately, the biopsy-proven clinical antibody-mediated rejection (AMR occurred in one case. Episo- de of AMR was successfully reversed. On 6, 4 and 2 months follow-up, serum creatinine levels were 117, 127 and 87 μmol/l, respectively. We consider ABO-incompatible transplantation as a safe and promising procedure in particu- lar cases for those patients having related but ABO-incompatible donors. Given the shortage of donor organs ABO- incompatible living donor kidney transplantation may become a treatment of choice for many patients.

    In ABO-incompatible (ABOi) kidney transplantation (KT) with low iso-agglutinin (IG) titers (IGT), standard pre-conditioning treatment might be excessive. To try to answer this question, we evaluated the pre-conditioning requirements of a group of ABOi KT with low ABO IGT in our center. Our main objective was to assess desensitization requirements for ABOi KT with low IGT (desensitization (rituximab and plasma exchange [PE]) requirements for ABOi KT with IGT desensitization protocol in ABOi KT donors with low titers of IG to reduce adverse effects, reduce cost, and simplify pre-transplant logistics.

    We report the clinical and pathological findings of a case of de novo minimal change disease (MCD) after ABO-incompatible living kidney transplantation. A 62-yr-old man with end-stage renal disease associated with type I diabetes received ABO-incompatible kidney transplantation from his 58-yr-old wife. Although allograft function was excellent immediately after surgery, massive proteinuria (35 g/d) appeared on post-transplantation day 5. After the allograft biopsy taken on post-transplantation day 6, he was treated with 12 cycles of plasma exchange, but the nephrotic-range proteinuria showed no remission. The biopsy specimen showed no significant pathological findings on light microscopy, but electron microscopy showed diffuse effacement of podocyte foot processes. Based on the diagnosis of de novo MCD, the patient received intravenous methylprednisolone pulse therapy, followed by high-dose steroid maintenance therapy. The steroid therapy induced complete remission of nephrotic syndrome and stable allograft function immediately, which was also maintained at one yr after the transplantation.

    A positive crossmatch indicates the presence of donor-specific alloantibodies and is associated with a graft loss rate of >80%; anti-ABO blood group antibodies develop in response to exposure to foreign blood groups, resulting in immediate graft loss. However, a desensitization protocol for highly HLA-sensitized and ABO-incompatible high-titer kidney transplantation has not yet been established. We treated 6 patients with high (≥1:512) anti-A/B antibody titers and 2 highly HLA-sensitized patients. Our immunosuppression protocol was initiated 1 month before surgery and included mycophenolate mofetil (1 g/d) and/or low-dose steroid (methylprednisolone 8 mg/d). Two doses of the anti-CD20 antibody rituximab (150 mg/m(2)) were administered 2 weeks before and on the day of transplantation. We performed antibody removal with 6-12 sessions of plasmapheresis (plasma exchange or double-filtration plasmapheresis) before transplantation. Splenectomy was also performed on the day of transplantation. Postoperative immunosuppression followed the same regimen as ABO-compatible cases, in which calcineurin inhibitors were initiated 3 days before transplantation, combined with 2 doses of basiliximab. Of the 8 patients, 7 subsequently underwent successful living-donor kidney transplantation. Follow-up of our recipients showed that the patient and graft survival rates were 100%. Acute cellular rejection and antibody-mediated rejection episodes occurred in 1 of the 7 recipients. These findings suggest that our immunosuppression regimen consisting of rituximab infusions, splenectomy, plasmapheresis, and pharmacologic immunosuppression may prove to be effective as a desensitization protocol for highly HLA-sensitized and ABO-incompatible high-titer kidney transplantation.

    The shortage of deceased donors led to an increase of living donor kidney (LDK) transplantations performed in the presence of donor-specific antibodies (DSA) or ABO incompatibility (ABOi) using various desensitization protocols. We herein analyzed 26 ABOi and 8 Luminex positive DSA patients who were successfully desensitized by anti-CD20, antigen-specific immunoadsorption and/or plasmapheresis to receive an LDK transplant. Twenty LDK recipients with non-donor-specific HLA-antibodies (low risk) and 32 without anti-HLA antibodies (no risk) served as control groups. 1-year graft survival rate and renal function was similar in all 4 groups (creatinine: 1.63 ± 0.5 vs 1.78 ± 0.6 vs 1.64 ± 0.5 vs 1.6 ± 0.3 mg/dl in ABOi, DSA, low risk and no risk group). The incidence of acute T-cell mediated rejections did not differ between the 4 groups (15% vs 12, 5% vs 15% vs 22% in ABOi, DSA, low risk and no risk), while antibody-mediated rejections were only found in the DSA (25%) and ABOi (7.5%) groups. Incidence of BK nephropathy (BKVN) was significantly more frequent after desensitization as compared to controls (5/34 vs 0/52, p = 0.03). We demonstrate favorable short-term allograft outcome in LDK transplant recipients after desensitization. However, the desensitization was associated with an increased risk of BKVN.

    Atypical hemolytic uremic syndrome (aHUS) in allograft kidney transplantation is caused by various factors including rejection, infection, and immunosuppressive drugs. We present a case of a 32 year old woman with aHUS four years after an ABO-incompatible kidney transplantation from a living relative. The primary cause of end-stage renal disease was unknown; however, IgA nephropathy (IgAN) was suspected from her clinical course. She underwent pre-emptive kidney transplantation from her 60 year old mother. The allograft preserved good renal function [serum creatinine (sCr) level 110-130 μmol/L] until a sudden attack of abdominal pain four years after transplant, with acute renal failure (sCr level, 385.3 μmol/L), decreasing platelet count, and hemolytic anemia with schizocytes. On allograft biopsy, there was thrombotic microangiopathy in the glomeruli, with a cellular crescent formation and mesangial IgA and C3 deposition. Microvascular inflammation, such as glomerulitis, peritubular capillaritis, and arteriole endarteritis were also detected. A disintegrin-like and metalloproteinase with thrombospondin type 1 motifs 13 (ADAMTS13) did not decrease and Shiga toxin was not detected. Donor-specific antibodies or autoantibodies, including anti-neutrophil cytoplasmic antibody and anti-glomerular basement membrane (anti-GBM) antibody, were negative. The patient was diagnosed with aHUS and received three sessions of plasmapheresis and methylprednisolone pulse therapy, followed by oral methylprednisolone (0.25-0.5 mg/kg) instead of tacrolimus. She temporarily required hemodialysis (sCr level, 658.3 μmol/L). Thereafter, her sCr level improved to 284.5 μmol/L without dialysis therapy. This case is clinically considered as aHUS after kidney transplantation, associated with various factors, including rejection, glomerulonephritis, and toxicity from drugs such as tacrolimus.

Early reports suggest that patients who have elevated serum anti-blood group antibody titers (anti-A/B before transplantation and a rebound antibody production after antibody removal may be at high immunological risk. With currently available immune modulation protocols and immunosuppressive therapy, excellent short- and long-term patient and graft survival rates have been achieved even in those with high anti-A/B antibody titers before plasmapheresis or immunoadsorption. Nonetheless, acute infection with an organism possessing surface markers analogous to blood group antigens such as carbohydrate structures on

    The aim of this study was to compare anti-ABO antibody levels as measured by means of flow cytometry (FCM) with the levels measured with the use of the column agglutination test (CAT), and to evaluate the clinical outcome as it relates to the baseline mean fluorescence intensity (MFI) ratio obtained by FCM. We reviewed 21 cases of ABO-incompatible kidney transplantation (ABO-i KT). In these patients, baseline IgG titers were measured with the use of both FCM and CAT methods. We investigated the correlation between levels measured by FCM and those by CAT with the use of correlation coefficients. Patients were classified into a high MFI ratio group (≥200; n = 7) or low MFI ratio group (ABO antibody levels measured by means of the FCM-based method were highly correlated with the levels measured with the use of CAT in cases of ABO-i KT. The decreased level of anti-ABO antibody measured by means of FCM after plasmapheresis suggests its potential as an effective and objective method for assessment of anti-ABO antibody levels.

    Blood group incompatibility in kidney transplants from a living donor can be successfully overcome by using various desensitization protocols: intravenous immunoglobulin, plasmapheresis (PP), immunoadsorption, and double filtration PP. From July 2010 to October 2013, we performed 10 ABO incompatible kidney transplantation (KT) procedures from a living donor. The desensitization protocol was based on rituximab and PP+cytomegalovirus immune globulin. All patients received induction with basiliximab, except 1 case treated with Thymoglobuline® (ATG) for the simultaneous presence of donor-specific antibody. Tacrolimus and mycophenolate mofetil were initiated at the time of desensitization and continued after the transplant. After a mean follow-up of 11.6±10.4 months, all patients are alive with a functioning graft. The mean serum creatinine concentration at 1 month, 3 months, 6 months, and 1 year was 1.48±0.29, 1.47±0.18, 1.47±0.27, and 1.5±0.27 mg/dl. Three episodes of acute cellular rejection occurred in 2 patients. There was only 1 case of BK virus infection, treated with reduction of immunosuppressive therapy. The protocol biopsy specimens at 1, 3, and 6 months were C4d positive in the absence of acute rejection. Desensitization with rituximab, PP, and anti-cytomegalovirus immune globulin allowed us to perform transplants from living donors to ABO incompatible recipients with excellent results and reduced costs.

    Full Text Available Since 2008 up to 2010 eight ABO-incompatible liver transplantations have been performed in our center: one of them was urgent liver transplantation to adult patient from deceased donor, other seven were transplantations of left lateral segment to children from living relative donors. Own experience, as well as world one, proves, that barrier of ABO-incompatibility can be overcome more successfully in liver transplantation, particularly in pediatric population, that in other solid organs transplantation. Good results can be achieved even with less ag- gressive immunosuppressive therapy. Recipient conditioning before operation can significantly improve results of ABO-incompatible liver transplantation, but as own experience has shown, often there’s no need to hold some special preparation of children, because their anti-ABO antibodies are very low or absent before transplantation and do not increase after it. Thereby ABO-incompatible liver transplantation is reasonable in urgent cases and in pediatric population because of the limited pull of living relative donors for children.

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

    Many papers have reported on pregnancy and delivery after liver transplantation, but there have been no reports on pregnancy after ABO-incompatible liver transplantation. This paper reports the first successful pregnancy and delivery of a newborn after ABO-incompatible liver transplantation for fulminant hepatic failure. The patient was a 39-year-old female. She had an ABO-incompatible liver transplantation, donated from her husband, due to subacute fulminant hepatitis of unknown etiology. She was taking tacrolimus, methylprednisolone, and mizoribine orally for the maintenance of immunosuppression at the time of discharge. She was discharged uneventfully on postoperative day 38 without any rejection episodes. At 1 year and 6 mo after transplantation, she indicated a wish to become pregnant. Therefore, treatment with mycophenolate mofetil was interrupted at that time. After two miscarriages, she finally became pregnant and delivered transvaginally 3 years after the transplantation. All of the pregnancies were conceived naturally. The newborn was female with a birth weight of 3146 g; the Apgar scores were 9 and 10. Delivery was performed smoothly, and the newborn exhibited no malformations. The mother and the newborn were discharged uneventfully. We suggest that pregnancy is possible for recipients after ABO-incompatible liver transplantation. PMID:28210092

    2014-01-01

    In recent years ABO incompatible kidney transplantation (KTx) has become a more or less clinical routine procedure with graft and patient survival similar to those of ABO compatible transplants. Antigen-specific immunoadsorption (IA) for anti-A and anti-B antibody removal constitutes in many centers an important part of the treatment protocol. ABO antibody titration by hemagglutination is guiding the treatment; both if the recipient can be transplanted as well as in cases of suspected rejections if antibody removal should be performed. Despite the overall success of ABO incompatible KTx, there is still room for improvements and an extension of the technology to include other solid organs. Based on an increased understanding of the structural complexity and tissue distribution of ABH antigens and the fine epitope specificity of the ABO antibody repertoire, improved IA matrices and ABO antibody diagnostics should be developed. Furthermore, understanding the molecular mechanisms behind accommodation of ABO incompatible renal allografts could make it possible to induce long-term allograft acceptance also in human leukocyte antigen (HLA) sensitized recipients and, perhaps, also make clinical xenotransplantation possible.

  4. Adult Living Donor Liver Transplantation with ABO-Incompatible Grafts: A German Single Center Experience

    2009-01-01

    Full Text Available Adult living donor liver transplantations (ALDLTs across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR. Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety.

However, ABO compatibility is not critical in allogenic hemopoietic stem cell transplantation (HSCT and approximately 40-50% of hemopoietic stem cell transplants are ABO incompatible. This incompatibility may be major, minor or bi-directional. Though there are descriptions of transfusion practice and protocols in ABO incompatible HSCT, there are considerable variations and transfusion support in these patients can be very challenging. Aims: The immunohematologic observations in two cases of bi-directional ABO incompatible HSCT have been described, and clinico-serologic correlation has been attempted. Materials and Methods: In both cases, peripheral blood stem cell harvests were obtained using the Cobe spectra cell separator. Immunohematologic assessments in the donor and recipient were done as a part of pre HSCT evaluation. Both the standard tube technique and column agglutination method (Ortho Biovue Micro Bead System was used. Antibody screen was done by column agglutination method using three cell panel (Surgiscreen cells. Isoagglutinin titration was done by the master dilution method and standard validated techniques were used. Results: The pattern of laboratory findings in the two cases was different and so were the clinical outcomes. Although there was early engraftment in the first case, the second case developed pure red cell aplasia and this was well-reflected in the immunohematologic assessments. Conclusion: Immunohematologic assessment correlated well with the clinical picture and could be used to predict clinical outcome and onset of complications in ABO incompatible HSCT.

    Full Text Available Background/Aim. Due to improved methods for removal of ABO isoagglutinins and novel immunosuppressive protocols, short and long term outcome in blood group incompatible is similar to blood group compatible kidney transplantation. The aim of this study was to determine the efficacy of our original method for removal of ABO isoagglutinins from the blood in ABO-incompatible kidney allograft recipients. Method. Between 2006 and 2008 twelve patients were transplanted from ABO incompatible living donors. Titers of ABO isoagglutinins were 4-128 (IgG. Immunosuppressive therapy started 14 days before kidney transplantation with rituximab, followed by a triple therapy (prednisone + tacrolimus + mycophenolate mofetil and the first plasma exchange (PE procedure, in which one plasma volume was substituted with albumin and saline on day 7 before transplantation. For selective extracorporeal immunoadsorption, the removed plasma was mixed with donor blood type filtered red blood cells, centrifuged and the supernatant separated and preserved. In the next PE procedure, the removed plasma was replaced with immunoadsorbed plasma, and so on. Titers of ABO agglutinins, renal allograft function and survival were followed-up. Results. The pre-transplant treatment consisting of 1-5 PE procedures and immunosuppressive therapy resulted in target ABO agglutinins titers below 4. During a 10-24 month follow-up three patients had an early acute rejection, one patient acute rejection and hemolytic anemia, two patients surgical complications and one of them lost his graft. In the post-transplant period, the titers of ABO antibodies remained below 4. All the patients had stable kidney allograft function with mean serum creatinine ±SD of 129 ± 45 μmol/l at the end of the study. Conclusion. Our method for removal of ABO antibodies was effective in a limited series of patients and short-term follow-up.

    The necessity of detection of other than the classical major histocompatibility complex (MHC) and MHC class I-related chain A (MICA) directed antibodies prior to organ transplantation has already been repeatedly reported. A commercial flow cytometric endothelial crossmatch (CM) using isolated peripheral blood tie-2 positive cells provides a tool to detect non-MHC antibodies in addition to antibodies directed to MHC class I and II. The vast majority of circulating tie-2 positive cells expresses HLA-DR but not the A, B blood group antigens. Tie-2 cells are circulating surrogate endothelial cells. In this retrospective study we evaluated the endothelial CM in 51 renal transplantations, 30 with ABO compatible grafts and 21 with ABO incompatible grafts. Fifteen of the ABO compatible recipients (group A) developed unexplained rejection episodes (RE) while the remaining 15 had no RE (group B). Five cases of group A and none of group B had a positive tie-2 CM before transplantation (p=0.042). A positive tie-2 CM was also correlated with graft failure in ABO compatible transplants (p=0.02). No significant correlation was found between a positive pre-transplant tie-2 CM and RE in the ABO incompatible group. This study strongly suggest that a positive tie-2 CM may predict post-transplantation complications in ABO compatible grafts while negative reactions are not predictive. The test is not significantly correlated with RE in ABO incompatible grafts possibly due to applied desensitization. Copyright © 2013 American Society for Histocompatibility and Immunogenetics.

    Background and Aims: Due to the shortage of donor livers, minor ABO-incompatible liver transplantations are commonly performed. Together with the allograft, immunocompetent B-lymphocytes, called passenger lymphocytes, are transplanted. In case of minor ABO-incompatibility, these passenger lymphocytes produce antibodies directed towards the recipient's red blood cells, which causes immune-mediated hemolysis, also known as the passenger lymphocyte syndrome (PLS). Although this is a self-limiting disorder, serious complications can occur, including graft failure. Retrospectively, we evaluated the role of PLS in minor ABO-incompatible liver transplantations performed at our center. Methods: A retrospective analysis was conducted for all minor ABO-incompatible liver transplantations performed at the Antwerp University Hospital between 2003 and 2015. All patient files were inspected for clinical and laboratory findings. In cases of PLS diagnosis, the applied treatment was also studied. Results: In total, 10 patients underwent a minor ABO-incompatible liver transplantation and 4 showed signs of PLS. All 4 PLS patients were treated with different therapeutic strategy, corresponding to the severity of hemolysis. In all 4 cases, PLS resolved following treatment. Conclusion: When performing minor ABO-incompatible liver transplantations, knowledge of PLS is elemental. Next to a high index of clinical suspicion, we suggest routine screening for markers of hemolysis, with emphasis on haptoglobin level and direct antiglobulin test, weekly in the first 4 weeks post-transplantation as well as in case of a sudden hemoglobin drop within the first 3 months after transplantation. Peri- and postoperative transfusion support using donor-compatible blood has been suggested to prevent the occurrence or limit the extent of hemolysis.

    ABO-incompatible living-donor liver transplantation (ABO-LDLT) is generally more difficult to perform than ABO-incompatible kidney transplantation. Despite introduction of rituximab, ABO-LDLT in non-responders is a still difficult issue. A 23-year-old woman with primary sclerosing cholangitis underwent LDLT. The recipient's blood type was 0(+) and the donor's was B(+). Rituximab was infused twice on preoperative day (POD) 14 and 7. Plasma exchange (PE) was performed on PODs 5, 3, 2, and 1. However, repeated PE failed to decrease the anti-B antibody titer. On the other hand, preoperative esophagogastroscopy revealed esophageal varices with red color sign. Therefore, simultaneous liver transplantation and Hassab operation were performed. The donor left lobe of the liver was orthotopically transplanted into the recipient following Hassab operation. Flow cytometry on the day of surgery showed that the frequencies of B cells (CD20+) and memory B cells (CD20+/CD27+) in the peripheral blood were 0.9% and 0.3%, respectively; flow cytometry of cells recovered from the spleen revealed that the frequencies of B cells and memory B cells were 2.5% and 2.4%, respectively. Acute cellular rejection occurred on POD 15, and was treated by steroid pulse therapy, leading to a decrease in the anti-B antibody titer. The liver was functioning well on POD 390 (AST 19, ALT 34). In non-responders to ABO-LDLT, anti-donor blood type antibody-producing cells remains in the spleen after the conventional preoperative regimen. Splenectomy is an option for ABO-LDLT non-responders.

    Full Text Available Immune hemolysis is one of the adverse effects that can occur following solid organ transplantation. Understanding the clinical settings and the various causes is necessary for prompt diagnosis and appropriate management. One such condition is passenger lymphocyte syndrome (PLS. This case report describes the case of a 27-year-old male renal allograft recipient of the B-positive blood group who received a kidney from an O-positive donor. Postoperatively, the patient showed declining hemoglobin (Hb level and was transfused with B-group packed RBCs (PRBCs, following which there was steep fall in Hb level. A request for PRBCs was sent to the blood bank and this time cross-match with B-group PRBCs showed incompatibility. The patient′s RBCs were found to be strongly DAT (direct anti-globulin test positive and the eluate showed the presence of anti-B with a titer of 32. Thus, diagnosis of probable PLS was made. The patient was managed with methylprednisolone, plasmapheresis and O-group PRBCs. Gradually his condition improved and was discharged in stable condition.

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

    A significant proportion of hematopoietic stem cell transplants are performed with ABO-mismatched donors. The impact of ABO mismatch on outcome following transplantation remains controversial and there are no published data regarding the impact of ABO mismatch in acute myeloid leukemia patients receiving haploidentical transplants. Using the European Blood and Marrow Transplant Acute Leukemia Working Group registry we identified 837 patients who underwent haploidentical transplantation. Comparative analysis was performed between patients who received ABO-matched versus ABO-mismatched haploidentical transplants for common clinical outcome variables. Our cohort consisted of 522 ABO-matched patients and 315 ABO-mismatched patients including 150 with minor, 127 with major, and 38 with bi-directional ABO mismatching. There were no significant differences between ABO matched and mismatched patients in terms of baseline disease and clinical characteristics. Major ABO mismatching was associated with inferior day 100 engraftment rate whereas multivariate analysis showed that bi-directional mismatching was associated with increased risk of grade II–IV acute graft-versus-host disease [hazard ratio (HR) 2.387; 95% confidence interval (CI): 1.22–4.66; P=0.01). Non-relapse mortality, relapse incidence, leukemia-free survival, overall survival, and chronic graft-versus-host disease rates were comparable between ABO-matched and -mismatched patients. Focused analysis on stem cell source showed that patients with minor mismatching transplanted with bone marrow grafts experienced increased grade II–IV acute graft-versus-host disease rates (HR 2.03; 95% CI: 1.00–4.10; P=0.04). Patients with major ABO mismatching and bone marrow grafts had decreased survival (HR=1.82; CI 95%: 1.048 – 3.18; P=0.033). In conclusion, ABO incompatibility has a marginal but significant clinical effect in acute myeloid leukemia patients undergoing haploidentical transplantation. PMID:28255020

    Full Text Available Herein, we describe an extremely rare experience of a patient with liver cirrhosis from hepatitis C virus (LC-HCV who underwent an ABO-incompatible living donor liver transplantation (ABO-I-LDLT using a hepatitis B core antibody (HBc-Ab positive donor’s liver graft. A 47-year-old Japanese woman with end stage LC-HCV, as a recipient, was preoperatively administered rituximab, mycophenolate mofetil, and steroids without plasma exchange. A routine ABO-I-LDLT procedure was applied using her daughter’s HBc-Ab positive liver graft. Prophylaxis of the hepatitis B virus (HBV infection using hepatitis B immunoglobulin (HBIG and entecavir had been properly administered. Three months after the ABO-I-LDLT, HCV hepatitis relapsed. To date, this patient has been under antiviral therapy and prophylaxis of HBV infection using HBIG, while entecavir has been continued. The cognitions and techniques with regard to ABO-I-LDLT, prophylaxis of HBV cross infection, various patterns of immunosuppression, and antiviral therapy for HCV relapse are indispensable in managing a transplant recipient. According to the prophylaxis of HBV cross infection under ABO-I-LDLT, it may be very important to keep the HBs-Ab titer higher than usual for HBV naïve recipients, because severe systemic immunosuppression can cause de novo hepatitis.

    BACKGROUND:Hematopoietic stem cel transplantation is an important means for clinical cure of hematologic malignancies, congenital hereditary diseases and autoimmune diseases. Although ABO-incompatibility has no effects on the survival of transplanted hematopoietic stem cels, the transfusion strategy to ABO-incompatible grafts in alogeneic hematopoietic stem cel transplantation is worth studying. OBJECTIVE:To explore the antigen-antibody changes during blood conversion after ABO-incompatible hematopoietic stem cel transplantation as wel as transfusion strategies. METHODS:Blood grouping, antibody detection, antibody titer determination, cross-match test were employed for antigen-antibody monitoring during blood conversion and pre-transfusion compatibility detection in 24 cases undergoing ABO-incompatible alogeneic hematopoietic stem cel transplantation. Another 30 cases undergoing ABO-compatible alogeneic hematopoietic stem cel transplantation were enroled as controls to select the appropriate blood. RESULTS AND CONCLUSION:Al of the 24 ABO-incompatible patients developed the hematopoietic reconstitution after transplantation, but both major and major-minor ABO incompatibility were different from ABO compatibility in the time of erythrocytic recovery (P < 0.05). According to the changes of ABO antigen and antibody during the blood conversion, the patients of major ABO incompatibility were selected the red blood cels of their own type, the patients of minor ABO incompatibility were selected the red blood cels of the blood group from patients to donors gradualy, and the patients of major-minor ABO incompatibility were selected the red blood cels from O-type blood to donor’s type gradualy. None of the 24 recipients presented hemolytic reaction during transplantation and after transfusion. Therefore, the transfusion strategy to ABO-incompatible grafts in alogeneic hematopoietic stem cel transplantation is dynamicaly varied according to the changes of patient’s ABO

    According to the Indian chronic kidney disease registry, in 2010 only 2% of end stage kidney disease patients were managed with kidney transplantation, 37% were managed with dialysis and 61% were treated conservatively without renal replacement therapy. In countries like India, where a well-organized deceased donor kidney transplantation program is not available, living donor kidney transplantation is the major source of organs for kidney transplantation. The most common reason to decline a donor for directed living donation is ABO incompatibility, which eliminates up to one third of the potential living donor pool. Because access to transplantation with human leukocyte antigen (HLA)-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end stage kidney disease patients. KPD is a rapidly growing and cost-effective living donor kidney transplantation strategy for patients who are incompatible with their healthy, willing living donor. In principle, KPD is feasible for any centre that performs living donor kidney transplantation. In transplant centres with a large living donor kidney transplantation program KPD does not require extra infrastructure, decreases waiting time, avoids transplant tourism and prevents commercial trafficking. Although KPD is still underutilized in India, it has been performed more frequently in recent times. To substantially increase donor pool and transplant rates, transplant centres should work together towards a national KPD program and frame a uniform acceptable allocation policy.

    Newborn infants with maternal-fetal ABO incompatibility are at a greater risk for developing subsequent significant hyperbilirubinemia, and therefore, prediction of probable risk factors, such as the degree of hemolysis, gains importance. In this study, we aimed to evaluate the effect of fetal-neonatal blood group on the severity of hemolysis and jaundice due to maternal-fetal ABO incompatibility. In a retrospective analysis of 166 cases with ABO hemolytic disease of the newborn, risk factors for the severity of jaundice were compared in infants with blood group A or B. Both groups had similar demographic parameters such as birth weight, gender and day of admission. Similarly, there were no statistically significant differences in hematological parameters, such as initial hemoglobin levels, initial and final indirect bilirubin levels, frequency of positive direct Coombs test and hemolytic findings on peripheral blood smear, duration of phototherapy, number of exchange transfusions, and intravenous immunoglobulin (IVIG) therapy (p>0.05). We conclude that blood type has no effect on the severity of the hemolytic jaundice in ABO incompatibility.

    One hundred and five biopsy specimens taken in different periods after 34 ABO-incompatible mismatched related kidney transplantations were examined to establish the patterns of humoral activity from the morphological changes and expression of C4d deposits in the peritubular capillaries. Severe reversible forms of acute humoral rejection (AHR) (2 patients) and minimal morphological manifestations (13 patients) were observed in the biopsy specimens taken as long as 2 months later in Group 1 (C4d+). In the early period, the minimal manifestations of AHR did not cause organ dysfunction; but in the late period, 5 of them developed chronic humoral rejection in persistent humoral activity; 4 grafts were removed 531,720, 1019, and 1252 days later. Group 2 (C4d-) (n = 19) showed no graft losses or significant chronic changes; the late minimal manifestations of AHR had no impact on the duration of organ function in 3 recipients. The timely detection of early humoral activity and minimal manifestations of AHR is needed for the measures taken to reduce a risk for late function loss of the grafted organ.

    AIM To report the first international living related two way kidney paired donation (KPD) transplantation from India which occurred on 17th February 2015 after legal permission from authorization committee. METHODS Donor recipient pairs were from Portugal and India who were highly sensitized and ABO incompatible with their spouse respectively. The two donor recipient pairs had negative lymphocyte cross-matching, flow cross-match and donor specific antibody in two way kidney exchange with the intended KPD donor. Local KPD options were fully explored for Indian patient prior to embarking on international KPD. RESULTS Both pairs underwent simultaneous uneventful kidney transplant surgeries and creatinine was 1 mg/dL on tacrolimus based immunosuppression at 11 mo follow up. The uniqueness of these transplantations was that they are first international KPD transplantations in our center. CONCLUSION International KPD will increases quality and quantity of living donor kidney transplantation. This could be an important step to solving the kidney shortage with additional benefit of reduced costs, improved quality and increased access for difficult to match incompatible pairs like O blood group patient with non-O donor and sensitized patient. To the best of our knowledge this is first international KPD transplantation from India. PMID:28280697

    Providing transplantation opportunities for patients with incompatible live donors through kidney paired donation (KPD) is an important strategy for easing the crisis in organ availability. KPD is can overcome the barriers when the only living potential donors are deemed unsuitable owing to an incompatibility of blood type, of human leukocyte antigen cross-match, or both. In KPD, the incompatibility problems with two donor recipient pairs can be solved by exchanging donors. In the absence of well-organized deceased donor program, or transplantation with desensitization protocol and ABO incompatible transplantation, living donor KPD promises hope to the growing number of patients suffering from end-stage renal disease in India. We report our first successful three-way KPD transplantation from India. In an era of organ shortage, this approach is relevant to encourage wider participation from KPD donors and transplant centers to prevent commercial transplantation.

    Recipients of ABO incompatible allogeneic HSCT present with unusual ABO groups and crossmatch problems accompanied by change of the ABO group from that of the host to the donor. We report on a patient undergoing major ABO incompatible allogeneic HSCT (donor/recipient: A/O) whose blood group was wrongly established to have completely switched to blood group A when using a routine tube method and micro gel column blood grouping card on the 68th day post transplantation. The major crossmatch test with added antiglobulin and blood group A red cells was still positive. After further investigation, an explanation was found because we could not detect IgG anti-A in the serum. At the same time, anti-A coated the patient's RBCs and could be identified using a heat elution method although the DAT was negative. We also found an obvious mixed field with the LISS-IAT gel card. Hence, routine methods of ABO grouping are unfit for ABO incompatible allogeneic HSCT patients and a micro column neutral gel card is recommended for forward typing especially to detect mixed fields and a LISS-IAT gel card or IAT tube method for detecting IgG anti-A/B in reverse typing.

    Unintentional ABO mismatch kidney transplantation can cause detrimental hyperacute rejection. We report the first successful ABO incompatible kidney transplantation from an AB para-Bombay donor to O recipient. At the initial evaluation, the donor's ABO type was discordance on the cell typing and serum typing, which typed to be 'O' as cell typing and 'AB' as serum typing. At the second investigation, it was confirmed that the donor had a unique, rare but not uncommon blood type AB para-Bombay which was incompatible with the recipient's blood group. The kidney transplantation was successfully performed by an ABO incompatible preconditioning, double filtration plasmapheresis (DFPP) and rituximab. The serum creatinine at 12 months post-transplantation was 1.3 mg/dL. The pathology of the kidney biopsy showed no signs of rejection.

    Among term infants, ABO incompatibility is a leading cause of hemolytic disease and neonatal jaundice. With respect to preterm infants, data are lacking. To evaluate the incidence and severity of ABO incompatibility hemolytic disease among preterm infants with respect to hemolytic and jaundice parameters. Clinical and laboratory data were collected retrospectively from the medical records of 118 ABO-incompatible preterms born at gestational age (GA) 29-34 weeks, as well as 118 controls matched for GA, birth weight, and multiplicity. All infants were born at the Sheba Medical Center Tel-Hashomer between 2009 and 2012. The study and control groups were similar on all maternal and neonatal outcome parameters. No differences between the groups were recorded throughout hospitalization regarding hematocrit levels or the need for blood transfusion. Bilirubin levels were higher among the study (ABO-incompatible) group during the first 10 days of life; however, no significant differences were found regarding the need for phototherapy. Upon evaluating subgroups divided by GA, we found no differences on any hematological and jaundice factors among preterms of 29-31 weeks, whereas among preterms of 32-34 weeks higher positive direct antiglobulin test (DAT) results (7% vs. 0% in the control, P = 0.014) as well as higher bilirubin levels were documented. Among ABO-incompatible preterm infants with GA 29-34 weeks, there is no evidence of significant hemolytic reaction derived from placental transfer of antibodies. With increasing GA, antibody transfer becomes more significant, resulting in more positive DAT results and greater incidence of neonatal jaundice. © 2016 Wiley Periodicals, Inc.

    Full Text Available Joseph Kahwaji, Chris Tong, Stanley C Jordan, Ashley A VoComprehensive Transplant Center, Transplant immunology Laboratory, HLA Laboratory, Cedars-Sinai Medical Center, Los Angeles, CA, USAAbstract: Rituximab (anti-CD20, anti-B-cell is now emerging as an important drug for modification of B-cell and antibody responses in solid-organ transplant recipients. Its uses are varied and range from facilitating desensitization and ABO blood group-incompatible transplantation to the treatment of antibody-mediated rejection (AMR, post-transplant lymphoproliferative disorder (PTLD, and recurrent glomerular diseases in the renal allograft. Despite these uses, prospective randomized trials are lacking. Only case reports exist in regards to its use in de novo and recurrent diseases in the renal allograft. Recent reports suggests that the addition of rituximab to intravenous immunoglobulin (IVIG may have significant benefits for desensitization and treatment of AMR and chronic rejection. Current dosing recommendations are based on data from United States Food and Drug Administration-approved indications for treatment of B-cell lymphomas and rheumatoid arthritis. From the initial reported experience in solid organ transplant recipients, the drug is well tolerated and not associated with increased infectious risks. However, close monitoring for viral infections is recommended with rituximab use. The occurrence of progressive multifocal leukoencephalopathy (PML has been reported with rituximab use. However, this is rare and not reported in the renal transplant population. Here we will review current information regarding the effectiveness of rituximab as an agent for desensitization of highly human leukocyte antigen-sensitized and ABO-incompatible transplant recipients and its use in treatment of AMR. In addition, the post-transplant use of rituximab for treatment of PTLD and for recurrent and de novo glomerulonephritis in the allograft will be discussed. In

    The first kidney transplant in Cuba was performed on 24 February 1970, using a cadaveric donor. In 1979, living donor kidney transplantation began between first-degree relatives. A total of 2775 patients are enrolled in renal replacement therapy in 47 hospitals across the country, 1440 of whom are awaiting kidney transplantation. Organs for the kidney program are procured in 63 accredited hospitals equipped for multidisciplinary management of brain death. Accordingly, over 90% of transplanted kidneys are from cadaveric donors. Identification of potential recipients is carried out through a national, computerized program that affords all patients the same opportunity regardless of distance from a transplant center, and selection of the most suitable candidate is based primarily on HLA compatibility.

    Ramesh Y Bhat; Pavan CG Kumar

    2014-01-01

    Background: Neonates with ABO hemolytic disease are at greater risk for developing significant hyperbilirubinemia. We aimed to determine whether sixth hour transcutaneous bilirubin (TcB) could predict such a risk. Methods: TcB measurements were obtained at the 6th hour of life in blood group A or B neonates born to blood group O, rhesus factor compatible mothers. Subsequent hyperbilirubinemia was monitored and considered significant if a neonate required phototherapy/exchange transfusion. The predictive role of sixth hour TcB was estimated. Results: Of 144 ABO incompatible neonates, 41(OA, 24; O-B, 17) had significant hyperbilirubinemia. Mean sixth hour TcB was significantly higher among neonates who developed significant hyperbilirubinemia than those who did not (5.83±1.35 mg/dL vs. 3.65±0.96 mg/dL, P4 mg/dL had the highest sensitivity of 93.5% and >6 mg/dL had the highest specifi city of 99%. Area under receiver operating characteristic curve was 0.898. Conclusion: Sixth hour TcB predicts subsequent significant hyperbilirubinemia in ABO incompatible neonates.

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

    Thrombotic microangiopathy (TMA) after kidney transplantation has various aetiologies, including acute antibody-mediated rejection, bacterial or viral infection and immunosuppressive drugs, particularly calcineurin inhibitors. We present the case of a 28-year-old woman who developed TMA 30 months after the transplantation of an ABO-incompatible kidney from a living unrelated donor. The patient developed a sudden onset of allograft renal dysfunction and became uremic. She was transferred to our institution from a community hospital with strongly suspected acute allograft rejection. Intensive treatments for both T- and B-cell mediated acute rejection, including steroid pulse therapy, double-filtration plasmapheresis, antithymocyte globulin (1.5 mg/kg × 14 days) and rituximab (100 mg), were initiated during haemodialysis. However, her renal allograft function did not improve. Histopathological analysis 8 days after the treatment indicated TMA, despite the absence of apparent acute T-cell- or acute antibody-mediated rejection. There were no symptoms of infectious diseases, such as intestinal haemorrhagic colitis or viral infection. We concluded that the use of oral contraceptives, which had been initiated 3 weeks before TMA onset for the treatment of irregular vaginal bleeding, was the aetiologic agent.

    Kidney transplantation after liver transplanta-tion (KALT) offers longer survival and a better quality of life to liver transplantation recipients who develop chronic renal failure. This article aimed to discuss the efifcacy and safety of KALT compared with other treatments. The medical records of 5 patients who had undergone KALT were retrospectively studied, together with a literature review of studies. Three of them developed chronic renal failure after liver transplanta-tion because of calcineurin inhibitor (CNI)-induced neph-rotoxicity, while the others had lupus nephritis or non-CNI drug-induced nephrotoxicity. No mortality was observed in the 5 patients. Three KALT cases showed good prognoses, maintaining a normal serum creatinine level during entire follow-up period. Chronic rejection occurred in the other two patients, and a kidney graft was removed from one of them. Our data suggested that KALT is a good alternative to dialysis for liver transplantation recipients. The cases also indicate that KALT can be performed with good long-term survival.

    The clinicopathological context of rejection after kidney transplantation was well recognized. Banff conferences greatly contributed to elucidate the pathogenesis and to establish the pathologic criteria of rejection after kidney transplantation. The most important current problem of renal transplantation is de novo donor-specific antibody (DSA) production leading chronic rejection and graft loss. Microvascular inflammation is considered as a reliable pathological marker for antibody-mediated rejection (AMR) in the presence of DSA. Electron microscopic study allowed us to evaluate early changes in peritubular capillaries in T-lymphocyte mediated rejection and transition to antibody-mediated rejection. Severe endothelial injuries with edema and activated lymphocyte invaded into subendothelial space with early multi-layering of peritubular capillary basement membrane suggest T-lymphocyte mediated rejection induce an unbounded chain of antibody-mediated rejection. The risk factors of AMR after ABO-incompatible kidney transplantation are important issues. Anti-ABO blood type antibody titre of IgG excess 32-fold before transplant operation is the only predictable factor for acute AMR. Characteristics of chronic active antibody-mediated rejection (CAAMR) are one of the most important problems. Light microscopic findings and C4d stain of peritubular capillary and glomerular capillary are useful diagnostic criteria of CAAMR. Microvascular inflammation, double contour of glomerular capillary and thickening of peritubular capillary basement are good predictive factors of the presence of de novo DSA. C4d stain of linear glomerular capillary is a more sensitive marker for CAAMR than positive C4d of peritubular capillary. Early and sensitive diagnostic attempts of diagnosing CAAMR are pivotal to prevent chronic graft failure.

Compared with rapamycin, everolimus is characterized by a shorter half-life and improved bioavailability. Prior to US Food and Drug Administration approval, a number of Phase II and III clinical trials were undertaken to evaluate the effectiveness of everolimus in combination with calcineurin inhibitors for preventing acute rejection and promoting allograft survival in kidney transplant recipients. In this report, we review the pharmacokinetic properties of everolimus, the clinical efficacy studies that led to its approval for use in kidney transplantation, as well as reported data on patient safety and tolerability associated with its use.Keywords: mTOR inhibitors, kidney transplantation, everolimus

  6. COMBINED HEART-KIDNEY TRANSPLANTATION

    Combined heart-kidney transplantation may be performed in carefully selected patients with end-stage heart disease and renal failure. There are two types of combined transplantation of heart and kidney: 1) simultaneous heart-kidney transplantation (SHKT) from the same donor; 2) staged transplantation of heart and kidneys from two genetically different donors. The ISHLT registry in 2014 reported an increase in the number of SHKT over the years: from 22 in 1994 to 97 in 2012. World experience d...

    Despite decades of experience with child bearing in women with kidney transplants, these pregnancies remain high risk with an increased prevalence of hypertension and pre-eclampsia. Infertility, common in women with end-stage renal disease, is rapidly restored after transplant although pregnancy rates appear lower in transplant recipients than the general public. Many unanswered questions exist, some old questions such as what is the optimal timing of pregnancy after transplant, whether breast feeding is safe, the long-term impact if any on the offspring, and whether pregnancy negatively affects the kidney graft; and some new questions such as whether to modify immunosuppression in a patient taking a mycophenolic acid-containing drug, whether kidney donation has a deleterious impact on future pregnancies, whether to use erythropoietin-stimulating agents, and the role of BK virus. Counseling about contraception and pregnancy after transplant should be initiated during the pretransplant evaluation process. It is important because of the rapid restoration of fertility that occurs after transplant as well as the many risks and unanswered questions that remain.

    Full Text Available Donor-recipient ABO and/or HLA incompatibility used to lead to donor decline. Development of alternative transplantation programs enabled transplantation of incompatible couples. How did that influence couple characteristics? Between 2000 and 2014, 1232 living donor transplantations have been performed. In conventional and ABO-incompatible transplantation the willing donor becomes an actual donor for the intended recipient. In kidney-exchange and domino-donation the donor donates indirectly to the intended recipient. The relationship between the donor and intended recipient was studied. There were 935 conventional and 297 alternative program transplantations. There were 66 ABO-incompatible, 68 domino-paired, 62 kidney-exchange, and 104 altruistic donor transplantations. Waiting list recipients (n=101 were excluded as they did not bring a living donor. 1131 couples remained of whom 196 participated in alternative programs. Genetically unrelated donors (486 were primarily partners. Genetically related donors (645 were siblings, parents, children, and others. Compared to genetically related couples, almost three times as many genetically unrelated couples were incompatible and participated in alternative programs (P<0.001. 62% of couples were genetically related in the conventional donation program versus 32% in alternative programs (P<0.001. Patient and graft survival were not significantly different between recipient programs. Alternative donation programs increase the number of transplantations by enabling genetically unrelated donors to donate.

    Because access to transplantation with HLA-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end-stage renal disease (ESRD) patient in India. We present a government and institutional ethical review board approved study of 56 ESRD patients [25 two-way and 2 three-way pairs] who consented to participate in KPD transplantation at our center in 2013, performed to avoid blood group incompatibility (n = 52) or positive cross-match (n = 4). All patients had anatomic, functional, and immunologically comparable donors. The waiting time in KPD was short as compared to deceased donor transplantation. Laparoscopic donor nephrectomy was performed in 54 donors. Donor relationships were spousal (n = 40), parental (n = 13), others (n = 3), with median HLA match of 1. Graft survival was 97.5%. Three patients died with functioning graft. 16% had biopsy-proven acute rejection. Mean serum creatinine was 1.2 mg/dl at 0.73 ± 0.32 months follow-up. KPD is a viable, legal, and rapidly growing modality for facilitating LDRT for patients who are incompatible with their healthy, willing living donor. To our knowledge, this is the largest single-center report from India.

  10. Hepatitis C and Kidney Transplantation

    2011-01-01

    Hepatitis C virus (HCV) infection is relatively common among patients with end-stage kidney disease (ESKD) on dialysis and kidney transplant recipients. HCV infection in hemodialysis patients is associated with an increased mortality due to liver cirrhosis and hepatocellular carcinoma. The severity of hepatitis C-related liver disease in kidney transplant candidates may predict patient and graft survival after transplant. Liver biopsy remains the gold standard in the assessment of liver fibrosis in this setting. Kidney transplantation, not haemodialysis, seems to be the best treatment for HCV+ve patients with ESKD. Transplantation of kidneys from HCV+ve donors restricted to HCV+ve recipients is safe and associated with a reduction in the waiting time. Simultaneous kidney/liver transplantation (SKL) should be considered for kidney transplant candidates with HCV-related decompensated cirrhosis. Treatment of HCV is more complex in hemodialysis patients, whereas treatment of HCV recurrence in SLK recipients appears effective and safe. PMID:21755059

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.

    The history of kidney transplantation is a history of many unsuccessful efforts and setbacks, but also the history of perseverance, pioneering spirit, and steadfast courage. The first successful transplantation of a dog kidney was done by the Austrian Emerich Ullmann (1861-1937) in 1902. The kidney was connected to the carotid artery of the dog and the ureter ended freely. The organ produced urine for a couple of days before it died. In 1909, there were efforts to transplant human kidneys from deceased patients to monkeys and in the following year the first xenotransplantation in humans was completed. Different kinds of donors were tried: dogs, monkeys, goats and lambs, all without success. In 1939, the first transplantation from a deceased human donor was done by the Russion Yurii Voronoy, the patient survived for only a couple of days, and the organ never worked. In 1953, the first temporarily successful transplantation of a human kidney was performed by Jean Hamburger in Paris. A 16-year-old boy received the kidney of his mother as living donor transplantation. Then in 1954, a milestone was made with the first long-term successful kidney transplantation by Joseph Murray: the transplantation was done between monozygotic twins; the organ survived for 8 years. For his efforts in kidney transplantation, Murray was honored with the Nobel Prize in medicine in 1990. In 1962, the first kidney transplantation between genetically nonrelated patients was done using immunosuppression and in 1963 the first kidney transplantation in Germany was done by Reinhard Nagel and Wilhelm Brosig in Berlin. The aim of this article is to present the history of kidney transplantation from the beginning until today.

  18. Features and ethical considerations associated with living kidney and liver transplantations in South Korea.

    Science.gov (United States)

    Kim, J H

    2014-12-01

    When the Organ Transplantation Act came into effect in 2000 in South Korea, living organ donations were legalized and the Korean Network for Organ Sharing (KONOS) had a duty to approve the application of donation. The number of living organ donors has increased and the waiting time of recipients has been steady or decreased. The Organ Transplantation Act mainly focuses on the informed consent process of donations, so unrelated directed donations are permitted unless there is a suspicion of organ trafficking. But the annual reports show that directed donations of unrelated and related donors may have an ethical concern about organ sales. The donations of family members show another ethical concern. The numbers of ABO-incompatible transplantations have steadily increased since 2008, and lineal descendants, including minors, comprised 61% of living liver donors in 2012. Addressing the unethical practices without inhibiting living organ donations is the current task in South Korea. Private agencies have actively operated the living organ donations programs. The web-based computerized organ exchange program has been cooperatively run by hospital-based organizations. The strict legal regulations that could decrease living organ donations are hard to adopt. In the current situation, the functions of the official system need to be more developed. A national organ exchange program run by KONOS could be an option which could reduce ABO-incompatible transplantations and relieve the ethical concern of organ sales in unrelated directed donations.

From March 2007 till January 2013 421 patients: 230 men (54,6% and 191 women (45,4%; mean age 43,07 ± 11,62 undergone 429 kidney transplantations in the department of pancreas and kidney transplantation of the Scientific-Research Institute of Emergency Care named after N.V. Sklifosovsky. In order to evaluate the condition and the function of the kidney transplant ultrasound investigation (daily andacquisition(weekly wereused. In cases of kidney dysfunction and assumption of vessel complications we used computerized tomography. Besides, we used daily analysis of biochemical and clinical parameters of blood and urine. Results. The most common vessel complication was the thrombosis of the microvasculature of the kidney transplant due to acute humoral and combined rejection resistant to antirejection therapy (n = 9; 2,1%; in 4 cases there was a breakage of the transplant due to the acute rejection and the urgent transplantatectomy in an effort to save the patient; thrombosis of the transplantat artery occurred in 1 case (0,23%; we observed 2 cases (0,46% of the artery stenosis and 2 cases (0,46% of venous thrombosis. Conclusion. Summary frequency of vessel complications in our clinic, including thrombosis due to rejection, was 3,49%. It fully corresponds with data obtained from the global medical community. The incidence of great vessel thrombosis was less than 1% which indicates the adequate prophylactic anticoagulation therapy. For the benefit of early diacrisis of complications Doppler sonography is needed. In case of assumption of vessel complications urgent acquisition, computerized tomography and/ or angiography are to be held.

    Background About 85.3% of hemolytic disease of the newborn (HDN) is caused by maternal-fetal ABO blood group incompatibility. However, there is currently no recommended “best” therapy for ABO incompatibility during pregnancy. Objectives To systematically assess the safety and effectiveness of oral Chinese herbal medicine (CHM) for preventing HDN due to ABO incompatibility. Methods The protocol of this review was registered on the PROSPERO website (No. CRD42016038637).Six databases were searched from inception to April 2016. Randomized controlled trials (RCTs) of CHM for maternal-fetal ABO incompatibility were included. The primary outcome was incidence of HDN. The Cochrane risk of bias tool was used to assess the methodological quality of included trials. Risk ratios (RR) and mean differences with 95% confidence interval were used as effect measures. Meta-analyses using Revman 5.3 software were conducted if there were sufficient trials without obvious clinical or statistical heterogeneity available. Results Totally 28 RCTs involving3413 women were included in the review. The majority of the trials had unclear or high risk of bias. Our study found that the rate of HDN and the incidence of neonatal jaundice might be 70% lower in the herbal medicine group compared with the usual care group (RR from 0.25 to 0.30).After treatment with herbal medicine, women were twice as likely to have antibody titers lower than 1:64 compared with women who received usual care(RR from 2.15 to 3.14) and the umbilical cord blood bilirubin level in the herbal medicine group was 4umol/L lower than in those receiving usual care. There was no difference in Apgar scores or birthweights between the two groups. Conclusions This review found very low-quality evidence that CHM prevented HDN caused by maternal-fetal ABO incompatibility. No firm conclusions can be drawn regarding the effectiveness or safety of CHM for this condition. PMID:28719639

    Chronic shortage of kidney transplants worldwide has led to the use of organs from so called marginal or borderline donors, now termed "expanded-criteria donors". There has been an emerging practice of dual kidney transplantation (DKT) to compensate for sub optimal nephron mass of such kidneys. We performed DKT in "Merkur" University Hospital in August 2005. The donor was a 72-year old female with a history of long-term hypertension, aneurysm of the posterior cerebral artery, cerebrovascular insult (CVI), and with normal creatinine values and kidney function at the time of explantation. Initial biopsy of donor kidneys revealed acute tubular damage, with connective changes in 22% and 11% of glomeruli in the left and the right kidney, respectively. The recipient was a 60-year old male diagnosed with the IgA nephropathy on the last biopsy in 1999, and on dialysis since November 2003. Postoperative course was uneventful without any surgical complications. A triple immunosuppressive protocol was used. On follow-up ultrasonography 4 years posttransplantation both kidneys appeared of normal size and parenchymal pattern and with no signs of dilatation of the canal system, and color Doppler examination demonstrated normal flow in both kidneys. In conclusion, the use of DKT ie. donors by the expanded-criteria will continue to increase, and further studies of the results will, with no doubt, support this method.

    Measurement of alloantibody titer to a red cell antigen (ABO titers) is an integral part of management of ABO incompatible kidney transplants (ABOiKT). There are different methods of titer estimation. Alloantibody detection by tube titration and Gel agglutination columns are accepted methodologies. It is essential to find the difference in titers between the two methods so as to set the 'cut-off' titer accordingly, depending upon the method used. We did a prospective observational study to compare and correlate the ABO titers using these two different techniques - conventional tube technique (CTT) and the newer column agglutination technique (CAT). A total of 67 samples were processed in parallel for anti-A/B antibodies by both tube dilution and column agglutination methods. The mean titer by conventional tube method was 38.5 + 96.6 and by the column agglutination test was 96.4 + 225. The samples correlated well with Spearman rho correlation coefficient of 0.94 (P = 0.01). The column agglutination method for anti A/B titer estimation in an ABO incompatible kidney transplant is more sensitive, with the column agglutination results being approximately two and half fold higher (one more dilution) than that of tube method.

    Secondary bladder amyloidosis is an extremely rare disease, resulting from a chronic systematic inflammatory disorder associated with amyloid deposits. Although uncommon in Japan, familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent episodes of fever of short duration and serositis and is frequently associated with systemic amyloidosis. Here, we present a case of a Japanese patient complaining of fever and macroscopic hematuria after a living donor renal transplantation. Consequently, he was diagnosed with secondary bladder amyloidosis with FMF. A 64-year-old Japanese male received a living ABO-incompatible kidney transplant from his wife. The postoperative clinical course was normal, and the patient was discharged 21 days after the transplantation with a serum creatinine level of 0.78 mg/dl. The patient frequently complained of general fatigue and fever of unknown origin. Six months later, the patient presented with continuous general fatigue, macroscopic hematuria, and fever. Cystoscopic examination of the bladder showed an edematous region with bleeding, and a transurethral biopsy revealed amyloid deposits. His wife stated that the patient had a recurrent high fever since the age of 40 years and that his younger brother was suspected to have a familial autoinflammatory syndrome; thus, the patient was also suspected to have a familial autoinflammatory syndrome. Based on his brother's medical history and the genetic tests, which showed a homozygous mutation (M694V/M694V) for the Mediterranean fever protein, he was diagnosed with FMF. Although colchicine treatment for FMF was planned, the patient had an untimely death due to heart failure. We re-evaluated the pathological findings of the various tissue biopsies obtained during the treatment after the renal transplantation. Immunohistochemistry revealed amyloid deposits in the bladder region, renal allograft, and myocardium and the condition was diagnosed as AA

    This article describes the background, beginnings, development, evolution and outcomes of kidney transplantation in Cuba. Nephrology as a medical specialty in Cuba began in 1962 and was formalized in 1966. Conditions were created to implement renal replacement therapy (including transplants), bring nephrology care to the entire country and train human resources who would assume this responsibility, making Cuba one of the first countries with a comprehensive program for renal patient care. After three unsuccessful cadaveric-donor kidney transplantations in 1968-69, the ensuing history of kidney transplantation can be summarized in the following three stages. 1970-1975: In January 1970, cadaveric-donor kidney transplantation began at the Nephrology Institute. That year, 17 kidney transplantations were performed; four of these patients lived with functional kidneys for 15-25 years; 10-year graft survival was 23.5% (Kaplan-Meier survival curve); HLA typing began in 1974. By December 1975, 170 grafts had been done in three hospitals. 1976-1985: Seven transplantation centers performed 893 grafts during this period. HLA-DR typing was introduced in 1976 and the National Histocompatibility Laboratory Network was founded in 1978. The first related living-donor kidney transplantation was done in 1979. 1986-2011: The National Kidney Transplantation Coordinating Center and the National Kidney Transplantation Program were created in 1986; the first combined kidney-pancreas transplantation was performed the same year. In 1990, cyclosporine and the Cuban monoclonal antibody IOR-T3 were introduced for immunosuppression to prevent rejection, as were other Cuban products (hepatitis B vaccine and recombinant human erythropoietin) for transplant patients. By December 2011, the cumulative number of transplants was 4636 (384 from related living donors). With over 40 years of experience, kidney transplantation is now well established in Cuba; it is free and universally accessible, on the

    Full Text Available Diabetes mellitus is one of the most important causes of chronic kidney disease (CKD. In patients with advanced diabetic kidney disease, kidney transplantation (KT with or without a pancreas transplant is the treatment of choice. We aimed to review current data regarding kidney and pancreas transplant options in patients with both type 1 and 2 diabetes and the outcomes of different treatment modalities. In general, pancreas transplantation is associated with long-term survival advantages despite an increased short-term morbidity and mortality risk. This applies to simultaneous pancreas kidney transplantation or pancreas after KT compared to KT alone (either living donor or deceased. Other factors as living donor availability, comorbidities, and expected waiting time have to be considered whens electing one transplant modality, rather than a clear benefit in survival of one strategy vs. others. In selected type 2 diabetic patients, data support cautious utilization of simultaneous pancreas kidney transplantation when a living kidney donor is not an option. Pancreas and kidney transplantation seems to be the treatment of choice for most type 1 diabetic and selected type 2 diabetic patients.

    Full Text Available Diabetes mellitus (DM is the most common cause of chronic kidney disease (CKD and end stage renal disease (ESRD. New onset diabetes mellitus after transplant (NODAT has been described in approximately 30 percent of non-diabetic kidney transplant recipients many years post transplantation. DM in patients with kidney transplantation constitutes a major comorbidity, and has significant impact on the patients and allografts’ outcome. In addition to the major comorbidity and mortality that result from cardiovascular and other DM complications, long standing DM after kidney transplant has significant pathological injury to the allograft, which results in lowering the allografts and the patients’ survivals. In spite of the cumulative body of data on diabetic nephropathy (DN in the native kidney, there has been very limited data on the DN in the transplanted kidney. In this review, we will shed the light on the risk factors that lead to the development of NODAT. We will also describe the impact of DM on the transplanted kidney, and the outcome of kidney transplant recipients with NODAT. Additionally, we will present the most acceptable data on management of NODAT.

  15. Optical Coherence Tomography in Kidney Transplantation

    Andrews, Peter M.; Wierwille, Jeremiah; Chen, Yu

    End-stage renal disease (ESRD) is associated with both high mortality rates and an enormous economic burden [1]. The preferred treatment option for ESRD that can extend patients' lives and improve their quality of life is kidney transplantation. However, organ shortages continue to pose a major problem in kidney transplantation. Most kidneys for transplantation come from heart-beating cadavers. Although non-heart-beating cadavers represent a potentially large pool of donor kidneys, these kidneys are not often used due to the unknown extent of damage to the renal tubules (i.e., acute tubular necrosis or "ATN") induced by ischemia (i.e., lack of blood flow). Also, ischemic insult suffered by kidneys awaiting transplantation frequently causes ATN that leads to varying degrees of delayed graft function (DGF) after transplantation. Finally, ATN represents a significant risk for eventual graft and patient survival [2, 3] and can be difficult to discern from rejection. In present clinical practice, there is no reliable real-time test to determine the viability of donor kidneys and whether or not donor kidneys might exhibit ATN. Therefore, there is a critical need for an objective and reliable real-time test to predict ATN to use these organs safely and utilize the donor pool optimally. In this review, we provided preliminary data indicating that OCT can be used to predict the post-transplant function of kidneys used in transplantation.

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

    Allograft thrombosis is a devastating early complication of renal transplantation that ultimately leads to allograft loss. We report here on our experience of nine cases of immediate re-transplantation following early kidney transplant thrombosis at a single centre between January 1990 and June 2009. The mean age was 42.9 years at time of transplant. For seven patients, the allograft thrombosis was their first kidney transplant and seven of the nine cases had a deceased donor transplant. The initial transplants functioned for a mean of 1.67 days and the patients received a second allograft at a mean of 3.1 days after graft failure. All of the re-transplants worked immediately. Four allografts failed after a mean of 52.5 months (2-155 months). Two of these died with a functioning allograft, one failed owing to chronic allograft nephropathy and one owing to persistent acute cellular rejection. The remaining five patients still have a functioning allograft after a mean of 101.8 months (7-187 months). One year allograft and patient survival after re-transplantation were 87.5% and 100% respectively (after 5 years, both were 57%). Immediate re-transplantation following early kidney transplant thrombosis can be a success. It may be considered in selected cases after allograft thrombosis.

    The critical shortage of kidneys available for transplantation has led to alternate strategies to expand the pool. Transplantation of the 2 kidneys into a single recipient using organs suboptimal for single kidney transplantation was suggested. We assessed results in 24 grafts allocated for dual kidney transplantation vs those in a control group of 44 designated for single kidney transplantation. Each group underwent pretransplant biopsy and recipients were age matched.

    Full Text Available Hypertension is a common complication of kidney transplantation with the prevalence of 80%. Studies in adults have shown a high prevalence of hypertension (HTN in the first three months of transplantation while this rate is reduced to 50- 60% at the end of the first year. HTN remains as a major risk factor for cardiovascular diseases, lower graft survival rates and poor function of transplanted kidney in adults and children. In this retrospective study, medical records of 400 kidney transplantation patients of Sina Hospital were evaluated. Patients were followed monthly for the 1st year, every two months in the 2nd year and every three months after that. In this study 244 (61% patients were male. Mean ± SD age of recipients was 39.3 ± 13.8 years. In most patients (40.8% the cause of end-stage renal disease (ESRD was unknown followed by HTN (26.3%. A total of 166 (41.5% patients had been hypertensive before transplantation and 234 (58.5% had normal blood pressure. Among these 234 individuals, 94 (40.2% developed post-transplantation HTN. On the other hand, among 166 pre-transplant hypertensive patients, 86 patients (56.8% remained hypertensive after transplantation. Totally 180 (45% patients had post-transplantation HTN and 220 patients (55% didn't develop HTN. Based on the findings, the incidence of post-transplantation hypertension is high, and kidney transplantation does not lead to remission of hypertension. On the other hand, hypertension is one of the main causes of ESRD. Thus, early screening of hypertension can prevent kidney damage and reduce further problems in renal transplant recipients.

  3. Opportunities to deter transplant tourism exist before referral for transplantation and during the workup and management of transplant candidates.

    Transplant tourism is a global issue, and physicians in the developed world may be in a position to actively deter this practice. To examine such opportunities, we identified 93 residents of British Columbia, Canada who had a kidney graft through tourism and determined their previous interactions with our transplant programs. These patients were mainly ethnic minorities (90%) who traveled to their country of origin for transplantation. Many tourists were transplanted early in their disease course, with 27 having a preemptive transplant. Among the 65 tourists referred for transplant, 33 failed to complete the evaluation. All tourists who completed an evaluation were placed on a waiting list in British Columbia and, after waiting a median of 2 years, pursued tourism. Most of these patients (62%) had a potential living donor, but none had an approved donor, with 13 donors found medically unsuitable, 8 ABO incompatible, and 12 who did not complete their evaluation. Thus, strategies to deter tourism should start before the development of end-stage renal disease and should be part of pretransplant workup and wait-list management, focusing on patients not progressing through their evaluation, those with a declined living donor, and those facing longer wait times, as these groups appear to be at higher risks for transplant tourism. Further studies are needed to identify individuals at risk for transplant tourism and to define effective strategies to deter these individuals.

    Over the last decade, there have been advances in kidney transplantation with introduction of minimally invasive surgery. Robotic surgery is becoming increasingly common across the specialities. There is now increasing experience in robotic kidney transplantation, though it remains a niche procedure. Initial reports suggest that this is a safe, feasible operation when performed by teams familiar with robotic surgery. There have been a few modifications to the initially described procedure, as a result of increasing experience. There is no significant difference in graft and patient survival when compared with open surgery and laparoscopic kidney transplantation. It is a safe procedure and therefore represents a viable alternative to open surgery in selected patients particularly the obese. The advantages include less postoperative pain and fewer wound complications such as surgical site infections and hernia, which could be particularly advantageous in the obese. Robotic kidney transplantation is procedure that has been developed over the last decade and could have applicability in kidney transplantation in the obese. Its main benefit is in enabling surgery in less accessible spaces due to body habitus, combined with those of using a smaller incision with less associated morbidity, with no inferiority in the reported primary outcomes of graft and patient survival. There are capital costs associated with this procedure, but further studies on the cost-effectiveness of robotic kidney transplantation are needed before it can be adopted widely.

    Concentration of bone marrow aspirates is an important prerequisite prior to infusion of ABO incompatible allogeneic marrow and prior to cryopreservation and storage of autologous marrow. In this paper we present our experience in processing 15 harvested bone marrow for ABO incompatible allogeneic and autologous bone marrow (BM) transplantation using Cobe Spectra® cell separator. BM processing resulted in the median recovery of 91.5% CD34+ cells, erythrocyte depletion of 91% and volume reduction of 81%. BM processing using cell separator is safe and effective technique providing high rate of erythrocyte depletion and volume reduction, and acceptable recovery of the CD34+ cells.

    Since the first successful procedure in 1954 kidney transplantation has become a standard therapy of end stage renal disease. The knowledge of immunoregulation and immune response of the body has enabled people to recognize acute rejection of organs. HLA-testing and organ exchange on basis of HLA-compatibility are extremely important for a successful kidney transplantation. A shortage of organs is limiting the further increase of transplantations. Chronic rejection is in most cases the reason for late graft failure. Further investigations to develop new immunosuppressive drugs and to clarify immunological processes underlying chronic rejections are necessary in the future.

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

    Thirteen rabbits were given cadmium injections to achieve cadmium concentrations in kidney cortex ranging from 0.05 to 1 mmole Cd/kg wet weight. Another four animals served as controls. One kidney from each animal was frozen directly to -70/sup 0/C whereas the other kidney was kept for 24 hr at +4/sup 0/C in a preservative (Sachs' solution) to simulate conditions for preservation of human donor kidneys before transplantation. Protein binding of cadmium, zinc and copper in kidney homogenates and the concentration of metallothionein (MT) were measured in the kidney that was frozen directly and in the kidney that had been preserved. No gross differences in either the protein binding of cadmium, zinc and copper or in the MT content were seen between the directly frozen and preserved kidney from the same animal. This indicates that MT is not rapidly broken down in rabbit kidneys which have been preserved similarly to human donor kidneys for 24 hr in a standard preservative solution prior to a transplantation. 27 references, 3 figures, 1 table.

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

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

    Women with renal disease, besides many dysfunctions, face increasing infertility and high-risk pregnancy due to uremia and changes of the hormonal functions. After renal transplantation, sexual dysfunction improves, providing the possibility of successful pregnancy for women of childbearing age. However, kidney transplanted patients are high-risk pregnant patients with increased maternal and fetal risks, and the graft also may be compromised during pregnancy; most studies report on several successive deliveries due to multidisciplinary team management. In clinical practice, the graft is rarely affected during the period of gestation. Fetal development disorders are also rare although preterm delivery and intrauterine growth retardation are common. For now, several studies and clinical investigations proved that, under multidisciplinary control, kidney transplanted female patients are also possible to have safe pregnancy and successful delivery. There are conflicting data in the literature about the prevention of complications and the timing of pregnancy. Herein, we would like to present some experience of our centre. A total of 847 kidney transplantations have been performed between June 1993 and December 2013 with 163 childbearing aged females (18–45 years) in our center. We report on three kidney transplanted patients who have given birth to healthy newborns. In our practice, severe complications have not been observed. PMID:26767122

    Alemtuzumab has been employed for induction therapy in kidney transplantation with low rates of acute rejection and excellent graft and patient survival. Antibody induction therapy has been linked to increased vulnerability to cancer. Data regarding malignancy rates with alemtuzumab are limited. We studied 1350 kidney transplant recipients (between 2001 and 2009) at the University of Pittsburgh Starzl Transplant Institute, for post-transplant de novo and recurrent malignancy, excluding non-melanoma skin cancer, among patients receiving alemtuzumab, thymoglobulin, and no induction therapies. Of the 1350 patients, 1002 (74.2%) received alemtuzumab, 205 (15.2%) received thymoglobulin, and 122 (9%) received no induction therapy. After excluding cancers occurring within 60 d post-transplantation, 43 (3.25%) malignancies were observed during a median follow-up time of 4.0 yr. The incidence of malignancy was 5.4% (1.09 per 100 patient-years [PY]) with thymoglobulin, 2.8% (0.74 per 100 PY) with alemtuzumab, and 3.3% (0.66 per 100 PY) with no induction (across all groups; p = 0.2342, thymoglobulin vs. alemtuzumab; p = 0.008). Thus, with the exception of non-melanoma skin cancer which we did not evaluate, alemtuzumab induction was not associated with increased cancer incidence post-kidney transplantation when compared to no induction therapy and was associated with lower cancer incidence when compared to thymoglobulin.

    Infectious complications remain a major cause of morbidity and mortality among transplant recipients. Urinary tract infection (UTI) is the most common infectious complication in kidney transplant recipients with a reported incidence from 25% to 75%, varies widely likely due to differences in definition, diagnostic criteria, study design, and length of observation. We sought reviews the incidence and importance of urinary tract infection on graft survival, the microbiology with special emphasis on multidrug resistant microorganisms, the therapeutic management of UTI and the prophylaxis of recurrent UTI among solid organ transplant recipients, highlighting the need for prospective clinical trials to unify the clinical management in this population.

    Full Text Available Structural urologic abnormalities resulting in dysfunctional lower urinary tract leading to end stage renal disease may constitute 15% patients in the adult population and up to 20-30% in the pediatric population. A patient with an abnormal bladder, who is approaching end stage renal disease, needs careful evaluation of the lower urinary tract to plan the most satisfactory technical approach to the transplant procedure. Past experience of different authors can give an insight into the management and outcome of these patients. This review revisits the current literature available on transplantation in abnormal bladder and summarizes the clinical approach towards handling this group of difficult transplant patients. We add on our experience as we discuss the various issues. The outcome of renal transplant in abnormal bladder is not adversely affected when done in a reconstructed bladder. Correct preoperative evaluation, certain technical modification during transplant and postoperative care is mandatory to avoid complications. Knowledge of the abnormal bladder should allow successful transplantation with good outcome.

    Full Text Available Abstract Introduction Calciphylaxis occurring after kidney transplantation is rare and rarely reported. It results in chronic non-healing wounds and is associated with a poor prognosis and is often fatal. We present a case of proximal lower limb calciphylaxis that occurred early after kidney transplantation. The patient had no classic associated risk factors. He had previously had a total parathyroidectomy but had normal serum calcium-phosphate product and parathyroid hormone levels. The clinical outcome of this case was favorable and highlights some fundamental issues relating to management. Case presentation A 70-year-old British Caucasian man with end-stage renal failure secondary to IgA nephropathy presented six months post kidney transplantation with cutaneous calciphylaxis lesions involving the medial aspect of the thigh bilaterally. Conclusion To the best of our knowledge, this is the first reported case of rapid onset cutaneous calciphylaxis occurring soon after kidney transplantation that was associated with a favorable outcome. Cutaneous calciphylaxis lesions should be promptly managed with meticulous wound care, antimicrobial therapy and the correction of calcium-phosphate product where indicated.

    Full Text Available Structural changes in eyes are present in all patients with chronic kidney disease. A study to detect ocular patho- logy in patients with end-stage chronic renal failure after kidney transplantation in the early and late postopera- tive period compared with patients receiving replacement therapy with hemodialysis. Revealed that in the early post-transplant period in recipients of kidneyas in patients on hemodialysis, continued angioretinopatiya, 40% of patients had «dry eye syndrome». In the delayed post-transplant period, patients showed significant impro- vement in the retina and retinal vessels, the improvement of spatial-temporal parameters of visual perception. However, a decrease of visual acuity on the background of the development of posterior subcapsular cataract caused by prolonged corticosteroid, and an increased incidence of viral and bacterial conjunctivitis. 

  13. Recurrent glomerular disease after kidney transplantation.

    2017-08-21

    With improving short-term kidney transplant outcomes, recurrent glomerular disease is being increasingly recognized as an important cause of chronic allograft failure. Further understanding of the risks and pathogenesis of recurrent glomerular disease enable informed transplant decisions, along with the development of preventive and treatment strategies. Multiple observational studies have highlighted differences in rates and outcomes for various recurrent glomerular diseases, although these rates have not markedly improved over the last decade. Emerging evidence supports use of rituximab to treat recurrent primary membranous nephropathy and possibly focal segmental glomerulosclerosis (FSGS), whereas eculizumab is effective in glomerular diseases associated with complement dysregulation [C3 glomerulopathy (C3G) and atypical hemolytic uremic syndrome (aHUS)]. Despite the potential for recurrence in the allograft, transplant remains the optimal therapy for patients with advanced chronic kidney disease (CKD) secondary to primary glomerular disease. Biomarkers and therapeutic options necessitate accurate pretransplant diagnoses with opportunities for improved surveillance and treatment of recurrent glomerular disease posttransplant.

    Kidney transplantation is the most suitable of ESRD care. The proportion of obese people is increasing in the general population and patients with kidney impairment. It is important to assess the impact of obesity on surgical complications of kidney transplantation. The aim of this retrospective study was to signify the correlation between obesity and the occurrence of postoperative urological complications during the first year. We conducted a retrospective study from March 1999 to December 2009. We conducted a chart review of patients undergoing kidney transplantation. The kidneys were taken from cadaveric donors. Data collected included age, weight, height, preoperative BMI; causal nephropathy, smoking, hypertension, diabetes, anticoagulation therapy. Intraoperative data included operative time (DO), cold ischemia. Urological complications were recorded during the first year after the kidney transplantation (vascular anastomotic strictures, ureterovesical stenosis, lymphorrheas, pyelonephritis, hematoma, wound infection). Statistical analysis consisted of a t-test for independent samples and univariate and multivariate logistic regression for the occurrence of complications. Four hundred and twenty-two patients were transplanted in total. We excluded 20 patients. BMI and duration of surgery patients with complications were significantly different from those of patients with no complications (P=0.016 and P=0.039, respectively). Obese (n=48) had more diabetes (12.5% versus 3.7%, P=0.014), were more often smoking (35.4% versus 22%, P=0.012), had a longer DO (203.64minutes versus 182.46minutes, P=0.006), and complications (62.5% versus 50.28%, P=0.03) than patients with a BMI <30 (n=354). After adjusting for age, smoking, DO, diabetes and BMI showed that only BMI was an independent predictor of the occurrence of postoperative complications with P=0.048 and RR=1.058 [CI: 1 to 1.119]. However, there was no more transplantectomy obese (P=0.911). Our study showed that

    The Canadian Renal Failure Register was established in 1980. Data have been collected annually for all Canadian patients in whom irreversible kidney failure developed and who required dialysis or transplantation. The authors present actuarial patient and graft survival rates for 1981-84. In 1984, patients with a functioning renal graft accounted for 43.9% of the patients with end-stage renal disease. The number of transplants performed increased from 482 in 1981 to 662 in 1984; however, 1,022 patients undergoing dialysis (25.2%) were on an active waiting list for a transplant at the end of 1984. Greater effort is needed to increase the transplantation rate. PMID:3530420

    Renal transplantation accounts for more than half of all solid organ transplants performed in the U.S., and the liver is the second most commonly transplanted solid organ. Although abdominal imaging procedures are commonplace in these patients, there has been relatively little attention paid to thoracic imaging applications. Preoperative imaging is crucial to aid in the exclusion of infectious or malignant disease. In the perioperative time period, thoracic imaging focuses both on standard intensive care unit care, including monitoring devices and their complications, and on the early infections that can occur. Postoperative management is divided into three time periods, and the principles governing the occurrence of infections and malignancies are reviewed. Anatomic and pathologic aspects unique to kidney and liver transplantation patients are also discussed.

    The decision for isolated kidney transplant (KT) vs. combined liver-kidney transplant (CLKT) in patients with end-stage renal disease (ESRD) with compensated cirrhosis remains controversial. We sought to determine outcomes of patients requiring listing for a liver transplant (LT) following either a cadaveric or living donor KT and compare these outcomes to similar patients receiving a CLKT. Our dataset included the United Network for Organ Sharing (UNOS)/Standard Transplant and Analysis and Research (STAR) kidney files from 1987 to 2012 after being joined with the liver files from 2002 to 2012. Outcomes of patients who received a CLKT with an international normalized ratio (INR) ≤1 and total bilirubin ≤1 were compared to patients who received a primary KT and subsequently required listing for LT between zero and five yr or after five yr. For the three groups, 244 patients had a CLKT, 216 were wait-listed for LT between zero and five yr after KT (0-5 WL), and 320 were wait-listed five yr after KT (+5 WL). From the time of KT, the 0-5 WL group had significantly worse survival than the CLKT group and the +5 WL group. The +5 WL had the best survival of all groups. For the 0-5 WL group, 45% underwent LT and 40% died while waiting compared to the +5 WL group with 53% having LT and 26% died while waiting. At the time of LT, the 0-5 WL group had a higher model for end-stage liver disease (MELD) score, higher incidence of being in the ICU at the time of transplant, and higher incidence of requiring life support. From the time of LT, the CLKT trended toward better survival (p = 0.0549) than both the 0-5 WL and +5 WL groups, which had equivalent survival. The 0-5 WL group is a higher risk group with poorer survival due to a higher incidence of dying on the waitlist. Better identification of patients with a high risk for hepatic decompensation following KT and agreement for regional exception for LT in the event of decompensation may improve utilization of organs and

    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.

    2007-01-01

    Failed renal allografts often are left in situ in patients who revert to chronic dialysis therapy or who undergo retransplantation. These organs may be the site of massive calcification despite their lack of physiological function. Calcification of an endstage renal allograft is sometimes found incidentally. We report here two patients who developed extensive calcification of the renal graft, one was on chronic hemodialysis and the other had a second renal transplantation with normal renal function. The precise pathogenesis of calcification and the factors which determine its tissue localization are unclear. Factors postulated to promote the development of metastatic calcification include an elevated calcium phosphate product, severe secondary hyperparathyroidism, aluminium toxicity and duration of dialytic therapy. In some cases local factors related with the chronic inflammatory rejection process are probably involved as well. However, the exact relative contribution of these factors remains unresolved. Unless specific clinical indications are present, transplant nephrectomy is not necessary for calcified end-stage renal allografts.

    Pancreas after kidney (PAK) transplantation has historically demonstrated inferior pancreas allograft survival compared to simultaneous pancreas and kidney (SPK) transplantation. Under our current immunosuppression protocol, we have noted excellent outcomes and rare immunological graft loss. The goal of this study was to compare pancreas allograft survival in PAK and SPK recipients using this regimen. This was a single center retrospective review of all SPK and PAK transplants performed between January 2003 and November 2007. All transplants were performed with systemic venous drainage and enteric exocrine drainage. Immunosuppression included induction with rabbit anti-thymocyte globulin (thymoglobulin), early steroid withdrawal, and maintenance with tacrolimus and sirolimus or mycophenolate mofetil. Study end points included graft and patient survival and immunosuppression related complications. Transplants included PAK 61 (30%) and SPK 142 (70%). One-yr patient survival was PAK 98% and SPK 95% (p = 0.44) and pancreas graft survival was PAK 95% and SPK 90% (p = 0.28). Acute cellular rejection was uncommon with 2% requiring treatment in each group. Survival for PAK using thymoglobulin induction, early steroid withdrawal and tacrolimus-based immunosuppression is at least comparable to SPK and should be pursued in the recipient with a potential living donor.

    2014-01-01

    Since its discovery in 1971, the BK virus, a human polyomavirus, has emerged as a significant cause of renal dysfunction and transplant graft loss in kidney transplant recipients. Improved screening methods have been effective in assisting in the early identification of the virus, and thus, prompt intervention to prevent the progression of the disease. Treatment options for the virus are limited; therefore, lowering immunosuppressive medications should be considered the first line of treatment. Current adjunctive therapies are not guaranteed to control the viral activity and may have limited therapeutic value.

    To clarify the incidence rate of post-transplant diabetes mellitus and associated risk factors in Japanese kidney transplant recipients, and to explore which treatment components are most effective in reducing post-transplant diabetes mellitus. We analyzed 849 Japanese non-diabetic adult recipients who had undergone living kidney transplantation and had received tacrolimus-based immunosuppression from 1996 to 2013 with a median follow-up of 5 years. In all, 127 patients developed post-transplant diabetes mellitus during the follow-up period. The incidence rate of post-transplant diabetes mellitus was 15.1% (95% confidence interval 12.7-17.5) at 5 years. Recipient age (hazard ratio 1.05, 95% confidence interval 1.05-1.06, P level at 2 weeks post-transplantation (hazard ratio 1.06, 95% confidence interval 1.03-1.09, P diabetes mellitus. Estimated 5-year predicted incidence rate after adjusting for age and obesity was 9.4% for recipients with a low tacrolimus trough level, and receiving mycophenolate mofetil and 38.4% for recipients with a high tacrolimus trough level and not receiving mycophenolate mofetil. Post-transplant diabetes mellitus is a common complication in Japan, similar to that in other Western countries. The present results show that an appropriate immunosuppressive regimen with a combination of tacrolimus and mycophenolate mofetil can reduce the likelihood of developing post-transplant diabetes mellitus. Clinical trials are required to confirm these findings. © 2016 The Japanese Urological Association.

    Strongyloides stercoralis is an uncommon infection in Saudi Arabia. It can establish latency and cause an autoinfection in humans that lasts for years. The infection can get reactivated during immunosuppression and can result in a life-threatening Strongyloides hyperinfection syndrome. We present three cases of renal transplant recipients who developed Strongyloides infection following transplantation. A bronchoalveolar lavage specimen, a duodenal biopsy and/or a stool specimen from these patients revealed evidence of S. stercoralis larvae. The first two patients received kidneys from the same deceased donor, a native of Bangladesh, an area that is highly endemic for S. stercoralis. The data suggest that the first two cases might be donor derived. High-risk donors and recipients should be screened for Strongyloides infection to initiate treatment before transplantation thus reducing morbidity and mortality.

    Mucormycosis is an uncommon opportunistic infection that is caused by Mucorales from the Zygomycetes class. Patients with severe immunodeficiency admitted to the hospital are at greatest risk for developing this infection. Mucormycosis usually is transmitted in humans by inhalation or inoculation of spores in the skin or mucous membranes. A 66-year-old man developed a surgical wound infection at 1 week after kidney transplant that did not improve despite broad-spectrum antibiotics and debridement. He was transferred to our hospital 45 days after transplant and had fever and a large purulent wound that was surrounded by a black necrotizing margin. Immunosuppressive drugs were discontinued and the dosage of prednisolone was decreased. Massive debridement was performed but was incomplete because he had full-thickness abdominal wall necrosis. Histopathology showed broad fungal hyphae without septation, consistent with the diagnosis of mucormycosis. Despite antifungal therapy with amphotericin B and additional debridement, the patient died of septic shock at 52 days after kidney transplant. Cutaneous fungal infections should be considered in the differential diagnosis of any nonhealing infected wound that does not respond to broad-spectrum antibiotics, especially in patients with predisposing risk factors such as transplant.

    Full Text Available Bulang He,1,2 Jeffrey M Hamdorf2 1Liver and Kidney Transplant Unit, Sir Charles Gairdner Hospital, Perth, WA, Australia; 2School of Surgery, The University of Western Australia, Perth, WA, Australia Aims: The aim of this paper was to review the current status of laparoscopic/robotic kidney transplant and evaluate its feasibility and safety in comparison with conventional standard "open" kidney transplant. Methods: An electronic search of PubMed, Embase, and the Cochrane library database was performed to identify the papers between January 1980 and June 2013 that reported on laparoscopic/robotic kidney transplantation. The terms "laparoscopic kidney/renal transplant" and "robotic kidney/renal transplant (transplantation" were used. Cross-referencing was also used to find the further publications. Only English language reports were selected and accepted for descriptive analysis. Results: A total of 17 papers and abstracts were retrieved. There were two case-control studies of small volume. High-level evidence comparing the safety and efficacy of laparoscopic/robotic kidney transplant with conventional open kidney transplant was not available at the time of this review. Conclusion: The limited published data have suggested that laparoscopic/robotic kidney transplant may offer the advantages of less pain, better cosmesis, possible shorter hospital stay, and fewer wound complications, without compromising graft function. Accordingly, some immunosuppressive agents, such as sirolimus, might be able to be commenced earlier, after laparoscopic/robotic kidney transplant. The techniques are various at this early stage. A uniformed operative technique may be established in the near future. With refinement of laparoscopic devices, this technique may be widely employed. Further studies will be needed to demonstrate the advantages of laparoscopic/robotic kidney transplant over the conventional open kidney transplant. Keywords: laparoscopic surgery, robotic

    Full Text Available Abstract Background Diabetes is a disease of increasing worldwide prevalence and is the main cause of chronic renal failure. Type 1 diabetic patients with chronic renal failure have the following therapy options: kidney transplant from a living donor, pancreas after kidney transplant, simultaneous pancreas-kidney transplant, or awaiting a deceased donor kidney transplant. For type 2 diabetic patients, only kidney transplant from deceased or living donors are recommended. Patient survival after kidney transplant has been improving for all age ranges in comparison to the dialysis therapy. The main causes of mortality after transplant are cardiovascular and cerebrovascular events, infections and neoplasias. Five-year patient survival for type 2 diabetic patients is lower than the non-diabetics' because they are older and have higher body mass index on the occasion of the transplant and both pre- and posttransplant cardiovascular diseases prevalences. The increased postransplant cardiovascular mortality in these patients is attributed to the presence of well-known risk factors, such as insulin resistance, higher triglycerides values, lower HDL-cholesterol values, abnormalities in fibrinolysis and coagulation and endothelial dysfunction. In type 1 diabetic patients, simultaneous pancreas-kidney transplant is associated with lower prevalence of vascular diseases, including acute myocardial infarction, stroke and amputation in comparison to isolated kidney transplant and dialysis therapy. Conclusion Type 1 and 2 diabetic patients present higher survival rates after transplant in comparison to the dialysis therapy, although the prevalence of cardiovascular events and infectious complications remain higher than in the general population.

    Full Text Available Primary hyperoxaluria is a rare autosomal recessive disease due to deficiency of an oxalate-metabolizing liver enzyme, which results in nephrolithiasis and renal failure. Concomitant liver and kidney transplant is recommended as isolated kidney transplant is inevitably complicated by recurrence of the disease. We present a 25-year-old man with end-stage nephrolithiatic renal disease who underwent bilateral nephrectomy, followed by kidney transplantation. There was progressive worsening of kidney function two weeks post transplant. Review of nephrectomy and transplant kidney biopsy showed abundant calcium oxalate crystals and further workup revealed hyperoxaluria, which was previously unsuspected. Later he developed fever, breathlessness, hemiparesis and died 10 weeks after transplant. Autopsy revealed multi-organ deposits of oxalate crystals as well as widespread zygomycosis. This case emphasizes the need for careful pre-transplant evaluation of patients with renal calculus disease in order to exclude primary hyperoxaluria.

    Transplantation of the horseshoe kidney can be performed en bloc or split into 2 grafts according to the vascular anomaly and the existence of the urinary collecting system in isthmus. From 2011 to 2014, there were 3 horseshoe kidney transplantations in Korea and transplantations were performed at 2 different centers. The transplantations were carried out successfully for all recipients without complications. All recipients have shown good graft kidney function after transplantation. No severe complication was revealed during follow-up period. We described the surgical technique used in the en bloc method to overcome various vascular anomalies and difficulties in choosing cannulation site and postoperative complications. En bloc transplantation of a horseshoe kidney is a useful strategy for patients with end-stage renal disease, and can provide favorable outcomes compared to the transplantation of a normal kidney.

    Until recently, human immunodeficiency virus (HIV) infection was an absolute contraindication to solid organ transplantation because it was feared that the anti-rejection therapy could result in accelerated HIV disease. At the end of the 1990s it became clear that HIV infection, once deemed a fatal disease, could be effectively turned into a chronic condition by the use of highly active antiretroviral therapy. Since then, the mortality rate from opportunistic infections has decreased dramatically, while liver and renal insufficiency have become the major causes of morbidity and mortality in these patients in the long term. A growing number of HIV patients develop end-stage renal disease secondary to immune-mediated glomerulonephritis, HIV-associated nephropathy, nephrotoxic effects induced by antiretroviral medication, or diabetic and vascular nephropathy, and therefore need maintenance dialysis. For this reason we have to reconsider kidney transplant as a possible treatment option. During the last decade, the results of many studies have shown that transplantation can be safe and effective as long as the HIV infection is effectively controlled by antiretroviral therapy. The short- and medium-term patient and graft survival rates in HIV-positive transplant recipients are comparable with those of the overall transplant population, but the incidence of acute rejection episodes is higher. The main clinical problem in the management of HIV-positive transplant recipients originates from the interference between immunosuppressive regimens and antiretroviral drugs. Thus, a close collaboration between infectious disease specialists and nephrologists is mandatory in order to optimize transplantation programs in these patients.

    2007-01-01

    BACKGROUND:Pancreas transplantation (PT) has proved effective but it is associated with a high risk of surgical complications and technical failure. Duct management and venous drainage are identiifed as major issues. Improvements in immunosuppression and prophylaxis greatly have contributed to surgical progress. DATA SOURCES: A literature search of the PubMed database (1996-2005) was conducted and research articles on PT reviewed. RESULTS: More than 23 000 PTs have been performed throughout the world. The majority (83%) were performed in combination with kidney transplantation [simultaneous pancreas-kidney transplantation (SPK)]. Pancreas graft survival rates at one year were 85% for 2001-2003 SPK cases, 79% for pancreas after kidney transplantation (PAK) cases, and 76% for pancreas transplantation alone (PTA) cases. For the 1999-2003 cases, enteric drainage was done in 79% of the SPK cases and bladder drainage in 21%. Patient survival rates, pancreas and kidney graft survival rates, and pancreas graft immunological failure rates did not differ signiifcantly in enteric versus bladder drainage cases. All the available data fail to demonstrate a deifnitive advantage of portal drainage over systemic drainage. From 1993 to 2002, the use of rabbit antithymocyte globulin increased from 0 to 37%;the use of daclizumab increased from 0 to 16%;and the use of basiliximab increased from 0 to 25%. In 1993, 98%of SPK recipients received cyclosporine;but this was decreased to 9% in 2002. Tacrolimus (FK506) usage has increased from 0 (1993) to 87%(2002) of SPK recipients. Sirolimus (SIR) usage has increased from 0 (1993) to 18%(2002) of SPK recipients. CONCLUSIONS: PT remains an effective therapy for treatment of type Ⅰ diabetes mellitus. Enteric drainage is currently predominant in SPK, but bladder drainage is still largely used. Portal drainage is as safe as systemic drainage, but there is still no convincing evidence about whether it is immunologically or metabolically

    Transplantation centers have historically considered a history of multiple myeloma as a contraindication to kidney transplantation due to high recurrence rates and poor transplant survival. However, there have been significant advances in the treatment of multiple myeloma, with improved patient survival, which may allow for successful kidney transplantation in these patients. We report on 4 patients who underwent kidney transplantation at our institution between 2009 and 2015 after having achieved a very good partial response or better with chemotherapy and autologous stem cell transplantation. All 4 patients received kidneys from living donors; 2 underwent induction therapy with basiliximab, and 2, with thymoglobulin. One patient had progression of myeloma, which responded well to therapy. All had functioning transplants at 1 year after kidney transplantation. No patients experienced a rejection episode or infections with BK polyomavirus or cytomegalovirus, with follow-up ranging from 16 to 58 months after kidney transplantation. Our experience suggests that kidney transplantation is feasible in a subset of patients with multiple myeloma. Future studies are necessary to compare outcomes in these patients with other high-risk patients undergoing kidney transplantation. Copyright © 2017 National Kidney Foundation, Inc.

    2016-03-01

    After transplantation of nonrenal solid organs, an acute decline in kidney function develops in the majority of patients. In addition, a significant number of nonrenal solid organ transplant recipients develop chronic kidney disease, and some develop end-stage renal disease, requiring renal replacement therapy. The incidence varies depending on the transplanted organ. Acute kidney injury after nonrenal solid organ transplantation is associated with prolonged length of stay, cost, increased risk of death, de novo chronic kidney disease, and end-stage renal disease. This overview focuses on the risk factors for posttransplant acute kidney injury after liver and heart transplantation, integrating discussion of proteinuria and chronic kidney disease with emphasis on pathogenesis, histopathology, and management including the use of mechanistic target of rapamycin inhibition and costimulatory blockade.

    Kidney transplantation is generally considered the best option for most patients with end-stage renal disease requiring renal replacement therapy, even for patients with graft failure. Here, we describe a case of a 49-year-old man who received his 1st kidney transplant the United Kingdom from his brother when he was 18 years old in. Thirty-one year after the first transplant, he underwent successful 4th living-unrelated kidney transplantation with no serious complications at our transplant center. He continued to have excellent allograft function and his latest serum creatinine 33 months after his 4th transplant was 1.2 mg/dL. To our knowledge, this is the first case of 4th kidney transplantation from Iran.

    Full Text Available Transplant biopsy has always been the gold standard for assessing the immune response to a kidney allograft (Chandraker A: Diagnostic techniques in the work-up of renal allograft dysfunction—an update. Curr Opin Nephrol Hypertens 8:723–728, 1999. A biopsy is not without risk and is unable to predict rejection and is only diagnostic once rejection has already occurred. However, in the past two decades, we have seen an expansion in assays that can potentially put an end to the “drug level” era, which until now has been one of the few tools available to clinicians for monitoring the immune response. A better understanding of the mechanisms of rejection and tolerance, and technological advances has led to the development of new noninvasive methods to monitor the immune response. In this article, we discuss these new methods and their potential uses in renal transplant recipients.

    A 39-year-old man complained of unspecific chest pains four years after kidney transplantation. Laboratory tests revealed a slow increase of retentions values; the value of soluble IL-2 receptor was slightly elevated. Computed tomography of the chest confirmed mediastinal and bilateral hilar masses. The broncho-alveolar lavage (BAL) showed a marked increase of the CD4/CD8 T-lymphocyte ratio and the aspiration cytology of these lymphadenopathies revealed the cytopathological characteristics of sarcoidosis. An asymptomatic stage I sarcoidosis was diagnosed, and the immunosuppressive treatment with cyclosporine, mycophenolatmofetil and prednisone was retained. The patient has remained asymptomatic for now six months. When bilateral hilar / mediastinal lymphadenopathies occur after organ transplantation with immunosuppression de novo sarcoidosis should be taken into account. © Georg Thieme Verlag KG Stuttgart · New York.

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

    A better understanding of high-cost kidney transplant patients would be useful for informing value-based purchasing strategies by payers. This retrospective cohort study was based on the Medicare Provider Analysis and Review (MEDPAR) files from 2003 to 2006. The focus of this analysis was high-cost kidney transplant patients (patients that qualified for Medicare outlier payments and 30-day readmission payments). Using regression techniques, we explored relationships between high-cost kidney transplant patients, center-specific case mix, and center quality. Among 43 393 kidney transplants in Medicare recipients, 35.2% were categorized as high-cost patients. These payments represented 20% of total Medicare payments for kidney transplantation and exceeded $200 million over the study period. Case mix was associated with these payments and was an important factor underlying variation in hospital payments high-cost patients. Hospital quality was also a strong determinant of future Medicare payments for high-cost patients. Compared to high-quality centers, low-quality centers cost Medicare an additional $1185 per kidney transplant. Payments for high-cost patients represent a significant proportion of the total costs of kidney transplant surgical care. Quality improvement may be an important strategy for reducing the costs of kidney transplantation.

    Full Text Available The objective of this study was to evaluate the current activity of pediatric versus adult kidney transplantation activity in the Arab world. A questionnaire was mailed to all kidney transplant centers in Arab countries to collect data on the kidney transplant activity in a recent single year. Three thousand three hundred and nine kidney transplants were performed in one year, with a transplant rate of 9.5 per million populations (PMP; 298 were performed for children with a pediatric kidney transplant (PKT rate of 0.87 PMP, which is much lower than that of developed countries where it mostly ranges from 5 to 10. The pediatric share of all transplants is 9%, which is twice as high as that of European children. Kidney transplant programs in most Arab countries rely exclusively on living donors as there is a severe shortage of deceased donors. 93.5% of all transplants, combined adult and pediatric, were from living donors. Deceased transplant activity in Arab countries accounts for 14-31% of all transplants in the three countries with deceased donor programs. Of the 212 adult and pediatric transplants that were performed from deceased donors in eight countries, only 29 cases were for pediatric recipients. Deceased PKT is available in the Kingdom of Saudi Arabia (KSA, Tunisia and Kuwait. Surprisingly, the PKT share was not better in the countries with higher overall kidney transplant rate and or in those where deceased transplant was available. PKT is still inactive in most Arab countries and mostly relies on living donors. The lack of well-developed deceased donor programs is the main issue to be addressed.

    Recently we described methods for optimizing the function of transplanted rat kidneys. In unilaterally nephrectomized recipients, one week after surgery, the left transplanted kidney was identical to the right native kidney with respect to wet weight and the clearances of inulin and para-aminohippuric acid (PAH). The goals of the present experiments were first, to extend the post-surgery period to three weeks (sufficient to allow hypertrophic changes), and second, to study function of transplanted hypertrophied kidneys. Genetically identical Brown Norway rats were used as donor and recipients. Three weeks after transplanting a normal kidney into a unilaterally-nephrectomized recipient, the transplanted kidney had a normal plasma flow and was identical to the contralateral native kidney with respect to wet weight and the clearances of inulin and PAH. Three weeks after transplanting a normal kidney into a bilaterally-nephrectomized recipient, the wet weight, inulin and PAH clearances, and plasma flow of the transplanted kidney were all higher than control, and not significantly different from those observed in unilaterally-nephrectomized control rats. Thus, transplanted and native kidneys exhibited the same degree of compensatory hypertrophy. Hypertrophied donor kidneys (that is, the donor rat had been unilaterally-nephrectomized three weeks previously) remained hypertrophied in bilaterally-nephrectomized recipients, but in unilaterally-nephrectomized recipients, they regressed towards normal (that is, the values of wet weight, inulin and PAH clearances and plasma flow were significantly less than those in rats with only one kidney) while the contralateral native kidney remained normal (values of wet weight and inulin and PAH clearances were not different from control).(ABSTRACT TRUNCATED AT 250 WORDS)

    1981-04-01

    Determination of bacteriuria, leucocyturia, active leucocytes and Sternheimer-Malbin's cells in patients with transplanted kidneys during the postoperative period provided identification of pyelonephritis in the transplanted kidney. E. coli, Proteus, Staphylococcus, P. aeruginosa and microbial associations were the main causative agents of pyelonephritis in such patients. The majority of the causative agents were polyresistant to antibiotics. Investigation of the microbial sensitivity to antibiotics and determination of their levels in the patients promote development of rational schemes for the treatment of pyelonephritis. Early identification of pyelonephritis of the transplanted kidney and its timely treatment with antibiotics allow avoiding destruction of the transplanted organ and promote its normal functioning.

    Living donor kidney transplantation (LDKT) is the optimal treatment for end-stage kidney disease (ESKD). The evaluation process for a kidney transplant is complex, time consuming, and burdensome to the ESKD patient. Also, race disparities exist in rates of transplant evaluation completion, transplantation, and LDKT. In December 2012 our transplant center implemented a streamlined, one-day evaluation process, dubbed Kidney Transplant Fast Track (KTFT). This paper describes the protocol of a two-part study to evaluate the effectiveness of KTFT at increasing transplant rates (compared to historical controls) and the TALK intervention (Talking About Live Kidney Donation) at increasing LDKT during KTFT. All participants will receive the KTFT evaluation as part of their usual care. Participants will be randomly assigned to TALK versus no-TALK conditions. Patients will undergo interviews at pre-transplant work-up and transplant evaluation. Transplant status will be tracked via medical records. Our aims are to: (1) test the efficacy and cost effectiveness of the KTFT in reducing time to complete kidney transplant evaluation, and increasing kidney transplant rates relative to standard evaluation practices; (2) test whether TALK increases rates of LDKT during KTFT; and (3) determine whether engaging in a streamlined and coordinated-care evaluation experience within the transplant center reduces negative perceptions of the healthcare system. The results of this two-pronged approach will help pave the way for other transplant centers to implement a fast-track system at their sites, improve quality of care by transplanting a larger number of vulnerable patients, and address stark race/ethnic disparities in rates of LDKT.

  9. AB32. Sexuality after kidney transplantation

    Zhang, Xiaodong

    2014-01-01

    Introduction Kidney transplantation is the treatment of choice for persons with ESRD, and in general, KTx recipients have increased survival rates and enjoy overall better QOL than those on dialysis However, one thing of QOL that does not seem to improve post-transplant is sexuality. In fact, one study found that sexuality was the only aspect of QOL that did not improve after transplantation. Roughly, 50% of males and at least the same percent of females. Sexuality is important to QOL and is considered a basic human right and an important component of general health by WHO. Sexuality is a central aspect of being human throughout life. Encompassing Related causes, difficulties with sexuality and sexual functioning are most likely a result of both psychological and physiological factors, side effects of required medications, weight gain, hirsutism, and loss of sexually attractive following KTx, post-transplant complications and/or comorbid conditions. Hypertension and depression require medications. Almost all transplant recipients have or will eventually develop one or more comorbid conditions (diabetes) or experience side effects from treatments (pretransplant dialysis) or medications that can have a negative effect on their sexuality or sexual functioning Publications The first studies that examined sexuality among persons with ESRD were done in the 1970s. Retrospectively compare their sexual functioning levels. One of the largest of these early studies, conducted by Levy, was a nationwide survey of 519 persons belonging to the National Association of Patients on Hemodialysis and Transplantation. Three sexual functioning questions. There are 48% of men and 26% of women reported the development of or worsening of a sexual dysfunction as their ESRD progressed. And 35% of males and 25% of females reported a worsening of sexual function at the start of HD. 59% of all male HD patients and 43% of all male KTx recipients considered themselves to be partially or totally

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

    Steroid-avoidance protocols have recently gained popularity in pediatric kidney transplantation. We investigated the clinical practice of steroid avoidance among 9494 kidney transplant recipients at 124 transplant centers between 2000 and 2012 in the Organ Procurement and Transplantation Network database. The practice of steroid avoidance increased during the study period and demonstrated significant variability among transplant centers. From 2008 to 2012, 39% of transplant centers used steroid avoidance in avoidance in 10-40% of transplant recipients, and 40% of transplant centers used steroid avoidance in >40% of discharged patients. Children receiving steroid avoidance more frequently received induction with lymphocyte-depleting agents. Repeat kidney transplants were the least likely to receive steroid avoidance. Children who received a deceased donor kidney, underwent pretransplant dialysis, were highly sensitized, or had glomerular kidney disease or delayed graft function were also less likely to receive steroid avoidance. The variation in practice between centers remained highly significant (p avoidance among transplant centers remain unexplained and may reflect uncertainty about the safety and efficacy of steroid-avoidance protocols.

    Immunoglobulin A (IgA) deposition in the native kidneys of patients with liver disease is well described. Secondary IgA nephropathy usually is thought to be benign, but hematuria, proteinuria, and loss of kidney function have been reported in this context. BK virus nephropathy is an important cause of kidney transplant loss; however, BK virus nephropathy is rare in the native kidneys of patients who underwent transplantation of other organs. We report the case of a patient with alcohol-related end-stage liver disease and chronic kidney disease with hematuria who underwent simultaneous liver-kidney transplantation. His kidney function decreased over the course of several weeks posttransplantation. Biopsy of the transplant kidney showed BK virus nephropathy, but no IgA deposits. In contrast, biopsy of the native kidneys showed IgA deposits, but no BK virus nephropathy. To our knowledge, this is the first reported case of a simultaneous liver-kidney transplantation wherein both the native and transplant kidneys were biopsied posttransplantation and showed exclusively different pathologies. These findings confirm the predilection of BK virus nephropathy for transplant rather than native kidneys.

    Patients who develop end-stage renal disease (ESRD) associated with Type I Diabetes Mellitus may receive kidney alone (KA) transplantation, simultaneous pancreas-kidney (SPK) transplantation, or a pancreas after kidney (PAK) transplantation. The goal of this study is to examine the long-term impact of pancreas transplantation on kidney graft and patient survival rates. A total of 85 transplantation cases, consisting of 30 that received living donor KA, 21 that received SPK, and 34 that receiv...

    Transplant tourism, a form of transplant commercialization, has resulted in serious short-term adverse outcomes that explain reduced short-term kidney allograft survival. However, the nature of longer-term outcomes in commercial kidney transplant recipients is less clear. To study this further, we identified 69 Canadian commercial transplant recipients of 72 kidney allografts transplanted during 1998 to 2013 who reported to our transplant center for follow-up care. Their outcomes to 8 years post-transplant were compared with 702 domestic living donor and 827 deceased donor transplant recipients during this period using Kaplan-Meier survival plots and multivariate Cox regression analysis. Among many complications, notable specific events included hepatitis B or C seroconversion (7 patients), active hepatitis and/or fulminant hepatic failure (4 patients), pulmonary tuberculosis (2 patients), and a type A dissecting aortic aneurysm. Commercial transplantation was independently associated with significantly reduced death-censored kidney allograft survival (hazard ratio 3.69, 95% confidence interval 1.88-7.25) along with significantly delayed graft function and eGFR 30 ml/min/1.73 m(2) or less at 3 months post-transplant. Thus, commercial transplantation represents an important risk factor for long-term kidney allograft loss. Concerted arguments and efforts using adverse recipient outcomes among the main premises are still required in order to eradicate transplant commercialization.

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

    Kidney failure after lung transplantation is a risk factor for chronic kidney disease. Calcineurin inhibitors are immunosuppressants which play a major role in terms of postoperative kidney failure after lung transplantation. We report our preliminary experience with the anti-interleukin-2 monoclonal antibody Basiliximab utilized as a "calcineurin inhibitor-free window" in the setting of early postoperative kidney failure after lung transplantation. Between 2012 and 2015 nine lung transplant patients who developed kidney failure for more than 14 days were included. Basiliximab was administrated in three doses (Day 0, 4, and 20) whilst Tacrolimus was discontinued or reduced to maintain a serum level between 2 and 4 ng/mL. Baseline glomerular filtration rate pre transplant was normal for all patients. Seven patients completely recovered from kidney failure (67%, mean eGFR pre and post Basiliximab: 42.3 mL/min/1.73 m(2) and 69 mL/min/1.73 m(2)) and were switched back on Tacrolimus. Only one of these patients still needs ongoing renal replacement therapy. Two patients showed no recovery from kidney failure and did not survive. Basiliximab might be a safe and feasible therapeutical option in patients which are affected by calcineurin inhibitor-related kidney failure in the early post lung transplant period. Further studies are necessary to confirm our preliminary results.

    In November 2006 in Japan, it was detected that there were 41 cases that diseased kidneys were harvested from patients and then were transplanted to other renal failure patients. This "Diseased kidney transplant" was prohibited in Japan since 2007 because of a lot of problems. On the other hand, in Japan, although there are about 12,000 patients on a waiting list for a transplant, only 10% of those get a transplant. Recently it appears that some patients have gone overseas for kidney transplants (transplant tourism). Concerning the background of transplant tourism, the issues are three points following. First, globalization caused recipients to go abroad easier and faster. Second, transnational law is difficult to institutionalize. Third, there is economical gap in not only international but also domestic. We should discuss again diseased kidney transplant in not only professionals but also in Japanese civilized society.

    We report a rare case of allograft loss from acute Page kidney secondary to trauma that occurred 12 years after kidney transplantation. A 67-year-old Caucasian male with a past surgical history of kidney transplant presented to the emergency department at a local hospital with left lower abdominal tenderness. He recalled that his cat, which weighs 15 lbs, jumped on his abdomen 7 d prior. On physical examination, a small tender mass was noticed at the incisional site of the kidney transplant. He was producing a normal amount of urine without hematuria. His serum creatinine level was slightly elevated from his baseline. Computer tomography revealed a large subscapular hematoma around the transplant kidney. The patient was observed to have renal trauma grade II at the hospital over a period of three days, and he was finally transferred to a transplant center after his urine output significantly decreased. Doppler ultrasound demonstrated an extensive peri-allograft hypoechoic area and abnormal waveforms with absent arterial diastolic flow and a patent renal vein. Despite surgical decompression, the allograft failed to respond appropriately due to the delay in surgical intervention. This is the third reported case of allograft loss from acute Page kidney following kidney transplantation. This case reinforces that kidney care differs if the kidney is solitary or a transplant. Early recognition and aggressive treatments are mandatory, especially in a case with Doppler signs that are suggestive of compression. PMID:28280700

    Sarcoidosis is a multisystemic disease of unknown etiology. Minor renal involvement is not rare but kidney failure is uncommon and only rare cases of recurrent disease in a kidney transplant have been published. We report a patient who at age 10 yr developed ESRD secondary to renal sarcoidosis with GIN. Her disease subsequently recurred in the transplanted kidney despite standard immunosuppression with prednisone, tacrolimus, and mycophenolate mofetil. The recurrent disease appeared to respond to increased immunosuppression, which included infliximab. However, the patient died of disseminated histoplasmosis three yr post-transplant.

    Full Text Available Living kidney donor transplantations are complex; add to that financial compensation to the donor and one enters an ethical maze. Debates on whether the buying and selling of kidneys should be allowed are mainly between utilitarians, deontologists and virtue ethicists as legal transplants are more common in the Western world. The pros and cons of each theory in relation to the sale of human organs are analysed, after which the foundational principles for all bio-ethical judgments; beneficence, non-maleficence, autonomy and justice are also scrutinised in seeking to justify the sale of human kidneys for transplantation purposes in a country with a human rights culture.

    This study reports major gastrointestinal complications in a group of 416 patients following kidney transplantation. Three hundred and ninety-nine patients received a cadaveric kidney while the other 17 received a living related organ. The immunosuppressive regimen changed somewhat during the course of the study but included azathioprine, prednisolone, antilymphocyte globulin, and cyclosporin. Perforations occurred in the colon (n = 6), small bowel (n = 4), duodenum (n = 2), stomach (n = 1), and esophagus (n = 1). There were five cases of acute pancreatitis, four of upper gastrointestinal and two of lower intestinal hemorrhage, two of acute appendicitis, one of acute cholecystitis, one postoperative mesenteric infarction, and two small bowel obstructions. Fifty percent of the complications occurred while patients were being given high-dose immunosuppression to manage either the early postoperative period or episodes of acute rejection. Ten percent of the complications had an iatrogenic cause. Of the 31 patients affected, 10 (30%) died as a direct result of their gastrointestinal complication. This high mortality appears to be related to the effects of the immunosuppression and the associated response to sepsis. Reduction of these complications can be achieved by improved surgical management, preventive measures, prompt diagnosis, and a reduced immunosuppressive protocol.

    Full Text Available 34-year-old man with chronic renal and pancreas failure in complicated diabetic disease received a kidney-pancreas transplantation. On the 32nd postoperative day, an acute kidney rejection occurred and resolved with OKT3 therapy. The patient also presented refractory urinary infection by E. Fecalis and M. Morganii, and a focal bronchopneumonia in the right-basal lobe resolved with elective chemotherapy. During the 50th post-operative day, an intense soft tissue inflammation localized in the first left metatarsal-phalangeal articulation occurred (Figure 1 followed by an abscess with a cutaneous fistula and extension to the almost totality of foot area. The radiological exam revealed a small osteo-lacunar image localized in the proximal phalanx head of the first finger foot. From the cultural examination of the purulent material, N. Asteroides was identified. An amoxicillin-based treatment was started and continued for three months, with the complete resolution of infection This case is reported for its rarity in our casuistry, and for its difficult differential diagnosis with other potentially serious infections.

    Light chain-associated kidney compromise is frequent in patients with monoclonal gammopathies; it affects the glomeruli or the tubules, and its most common cause is multiple myeloma. It may develop after a kidney transplant due to recurrence of a preexisting multiple myeloma or it can be a de novo disease manifesting as graft dysfunction and proteinuria. A kidney biopsy is always necessary to confirm the diagnosis.We describe three cases of kidney graft dysfunction due to multiple myeloma in patients without presence of the disease before the transplant.

    Saland, Jeffrey M; Ruggenenti, Piero; Remuzzi, Giuseppe

    2009-05-01

    Atypical hemolytic uremic syndrome is often associated with mutations in genes encoding complement regulatory proteins and secondary disorders of complement regulation. Progression to kidney failure and recurrence with graft loss after kidney transplantation are frequent. The most common mutation is in the gene encoding complement factor H. Combined liver-kidney transplantation may correct this complement abnormality and prevent recurrence when the defect involves genes encoding circulating proteins that are synthesized in the liver, such as factor H or I. Good outcomes have been reported when surgery is associated with intensified plasma therapy. A consensus conference to establish treatment guidelines for atypical hemolytic uremic syndrome was held in Bergamo in December 2007. The recommendations in this article are the result of combined clinical experience, shared research expertise, and a review of the literature and registry information. This statement defines groups in which isolated kidney transplantation is extremely unlikely to be successful and a combined liver-kidney transplant is recommended and also defines those for whom kidney transplant remains a viable option. Although combined liver-kidney or isolated liver transplantation is the preferred therapeutic option in many cases, the gravity of risk associated with the procedure has not been eliminated completely, and assessment of risk and benefit requires careful and individual attention.

    2016-01-01

    Infective endocarditis in a patient after kidney transplantation is a serious infective complication which increases the risk of loss of the graft and also the mortality of patients. The most important predisposing factor is the immunosuppressive therapy - mainly induction immunosuppression.Material and case description: 250 patients underwent kidney transplantation throughout the period of 12 years in the Transplant Center Martin. This set of patients included 5 patients (2 %) after heart valve replacement. We present the case of a patient after kidney transplantation with development of endocarditis of the bioprosthesis of the aortic valve one month after successful kidney transplantation. Diagnostics of endocarditis by standard procedures (examination by transthoracic echocardiogram, transesophageal echocardiography, hemocultures) was unsuccessful. We rarely diagnosed endocarditis only by PET-CT examination with a consequent change of the antibiotic treatment and successful managing of this post-transplant complication. Endocarditis after kidney transplantation is a serious complication which significantly worsens the mortality of patients. The risk of development of infective endocarditis after transplantation is also increased by induction, mainly by antithymocyte globulin. Diagnostics only by PET-CT examination is rare; however, in this case it fundamentally changed the approach to the patient and led to a successful treatment.

  12. The histo-blood group ABO system and tissue transplantation.

    In general, one might expect that ABO incompatibility of donor and recipient would be important to some degree if viability of the transplanted allograft is important for graft incorporation and function. This is true for some recipients of organs. However, ABO incompatibility appears to play a minor role, if any, in the clinical success of viable cornea and viable skin allografts. Even though A and B antigens may be present on the transplanted tissue, other factors that can contribute include the strength of the immune response, the avidity of the antibody, and the dose of the antigen presented, which may vary from donor to donor. Although A and B antigens are present on endothelium, the use of ABO-incompatible heart valves is successful, as they carry out their mechanical function by using the strength of the connective tissue rather than the viability of the donor endothelium. The presence, immunogenicity, and significance of A and B antigens in human vessel transplants have not been well studied. With the more commonly transplanted tissue, such as bone and tendon, posttransplant success does not depend on cellular viability or ABO compatibility.

    In the latter part of 2009, the Department of Health of the Philippines prohibited kidney transplantation with non-related kidney donors. Hence, the National Kidney and Transplant Institute created a Hospital Transplant Ethics Committee. This study describes directed non-related kidney donation at the National Kidney and Transplant Institute. This retrospective study reviewed the profiles of recipients and directed living non-related kidney transplant donors submitted to the Hospital Transplant Ethics Committee. A total 74 recipients and donors were reviewed by the Hospital Transplant Ethics Committee in 2014. Donors initiated the talks about being a donor (75%) to repay the good deeds that were done by the recipient for them or their families; examples of which are: sometime in their lives they needed financial assistance for hospitalization for their relatives and it was the patient who paid the hospital bill; or because they pitied the recipient, whom they found to be a good person, thus they would want to give one of their kidneys. Seventy-four (100%) said that they were not expecting anything in return for this act but wanted to be of help to the recipient. Of these 74 cases, 70 cases (95%) were approved and the others were disapproved. With a Hospital Transplant Ethics Committee in place, directed kidney donation is a valuable tool as an additional source of kidney donor without violating any ethical issues. Copyright © 2016.

    We investigated the prevalence, risk factors, and consequences of hepatitis G virus (HGV) infection in 87 kidney transplant recipients. Infection was diagnosed with reverse transcriptase polymerase chain reaction using primers in the NS3 region of the viral genoma. Twenty-four patients (27.5%) were HGV RNA positive (HGV+ group) and 63 patients (72.5%) were HGV RNA negative (HGV- group). No statistically significant differences were found between the two groups for age, sex, transplantation and hemodialysis duration, number of kidney transplantations, serum creatinine, history of transfusions, hepatitis B and C virus infections, and percentage of patients having suffered from acute rejection. Acute and chronic hepatitis were not more prevalent in the HGV+ group than in the HGV- group. HGV infection is highly prevalent in kidney transplant recipients but does not alter liver or kidney functions. HGV contamination may be linked to nosocomial transmission during long-term hemodialysis.

    Kidney transplantation is the best treatment for end-stage chronic renal disease. In Uruguay, the prevalence of patients on dialysis is 757 patients per millon inhabitants, plus 316 alive with a functioning renal graft. We install a preemptive renal transplantation program. Twenty-five patients received grafts without dialysis from 2004 to 2013, 5 receiving their 2nd transplantation and 17 from cadaveric donors, with 7.4 ± 7.7 months in the waiting list. At 24 months, patients' survival rate was 100% and the grafts' 97%, with a serum creatinine of 1.4 ± 0.6 mg%. The developed programs of dialysis and renal health care contributed install our preemptive kidney transplantation. Kidney transplantation should be proposed to selected patients with chronic renal failure as primary therapy of substitution of renal function.

    2017-08-01

    Conclusions. The kidney transplantation policies should be revised, such that timing of waitlist qualification is more standardized. We suggest that mention of using calculated creatinine clearance be dropped from the Organ Procurement and Transplantation Network policy wording and the units to quantify kidney function be changed to mL/min per 1.73 m2. Some consideration should be given to whether requiring persistently reduced renal function would better identify patients most likely to benefit from earlier waitlist qualification.

    We present the first single-center report of 2 consecutive cases of combined heart and kidney transplantation after insertion of a total artificial heart (TAH). Both patients had advanced heart failure and developed dialysis-dependent renal failure after implantation of the TAH. The 2 patients underwent successful heart and kidney transplantation, with restoration of normal heart and kidney function. On the basis of this limited experience, we consider TAH a safe and feasible option for bridging carefully selected patients with heart and kidney failure to combined heart and kidney transplantation. Recent FDA approval of the Freedom driver may allow outpatient management at substantial cost savings. The TAH, by virtue of its capability of providing pulsatile flow at 6 to 10 L/min, may be the mechanical circulatory support device most likely to recover patients with marginal renal function and advanced heart failure.

    Full Text Available Acute rejection episodes (AREs are a major determinant of renal allograft survival. The incorporation of new immunosuppressive agents explains, at least partially, the improvement seen in the results of transplantation in recent years. The objectives of this study are to analyze the incidence and severity of AREs, their risk factors and their influence on graft and patient survival. We retrospectively studied 280 kidney transplants performed in adults at the Charles Nicolle Hospital, Tunis, between 1986 and 2004. The diagnosis of ARE was based on clinical data and response to treatment. Allograft biopsies were performed in ten cases. The treatment of AREs consisted of pulse methylprednisolone and anti-thymocyte globulin. There were 186 males (66.4% and 94 females (33.6%, and their mean age was 31 ± 8.9 years. Overall, the 280 study patients experienced a total of 113 AREs. Of them, 85 had only one ARE, 28 had two to three and none had more than three AREs. A total of 68 AREs were completely re-versible, 42 were partially reversible while three could not be reversed with treatment. The mean inci-dence of AREs was 40.4%. The incidence was > 45% between 1986 and 1997, decreased to 20.5% between 1998 and 2000 and to 9% between 2001 and 2004. Graft survival rates in patients with and without AREs were respectively 91% and 93% at three years, 82% and 90% at five years and 73% and 83% at 10 years. We found a decrease in the incidence of AREs in recent years in our study patients, and this was related to the introduction of sensitized cross-match and the newer immunosuppressive agents, particularly MMF. Additionally, AREs had a deleterious impact on late graft survival in our study population.

    BACKGROUND:When liver or kidney transplant can respectively cure end-stage liver or kidney disease, neither hepatic graft nor renal transplant alone can be used as a radical therapy for diseases which involve both liver and kidney. Combined liver and kidney transplantation commenced late in China, and the number of transplants has been limited. This study was designed to assess the effects of simultaneous combined liver and kidney transplantation (SLKT) on end-stage liver and kidney diseases. METHODS:Fifteen patients who had received SLKT from 1996 to 2006 in the First Afifliated Hospital of Sun Yat-Sen University were reviewed. They included 5 patients with polycystic liver and kidney, 5 patients with hepatic cirrhosis and renal failure, and 5 patients with fulminant hepatic failure and hepatorenal syndrome (11 men and 4 women; average age 43.5 years). All patients had combined liver and kidney transplantation. RESULTS:The 5 patients with polycystic liver and kidney have survived for more than one year after SLKT, and the longest survival has been 5 years. Three of the 5 patients with hepatic cirrhosis and renal failure have survived more than two years; one died perioperatively and the other died from recurrence of hepatitis B 18 months after the operation. Three of the 5 patients with fulminant hepatic failure and hepatorenal syndrome have survived for two years, and 2 died of multiple organ failure during the operation.CONCLUSIONS:SLKT is an effective therapy for end-stage liver and kidney disease but the indications of SLKT for hepatorenal syndrome should be strict. SLKT may immunologically protect the renal graft.

    Background:Recently,the most common incision for kidney transplantation (KT) is an inverted J-shaped incision known as the "hockey-stick." However,demands for minimally invasive surgery in KT are increasing as in other various fields of surgery.Hence,we evaluated whether there is difference between minimal skin incision technique in kidney transplantation (MIKT) and conventional KT (CKT).Methods:Between June 2006 and March 2013,a total of 452 living kidney transplant patients were enrolled.The MIKT group included 17 young unmarried women whose body mass index was <25 kg/m2 and had no anatomic variation.The CKT group included 435 patients.The MIKT operation technique restricted to the 10 cm-sized skin incision in the lower right abdomen from laterally below the anterior superior iliac spine to the midline just above the pubis was performed.We compared the baseline clinical characteristics and postoperative results between two groups.For proper comparison,propensity score matching was implemented.Results:There was no difference in graft function,survival,and postoperative complication rate between MIKT and CKT groups (all P > 0.05).The 5-year graft survival was 92.3% and 85.7% in MIKT and CKT groups,respectively (P =0.786).Conclusions:Our results indicated that MIKT showed more favorable cosmetic results,and there were no statistical differences in various postoperative factors including graft function,survival,and complications compared with CKT.Hence,we suggested that MIKT is an appropriate method for selected patients in living KT.

    Infections remain a frequent complication following organ transplantation. Agents present within the general population remain common in recurrent infections among renal transplant recipients. Data mining methodology has become a promising source of information about patterns in the organ transplant recipient population. The aim of the study was to use data mining to describe the factors influencing single and recurrent infections in kidney transplant recipients. A group of 159 recipients who underwent kidney transplantation between 2005 and 2008 was analysed. RapidMiner and Statistica softwares were used to create decision tree models based on CART Quinlan and C&RT algorithms. There were 171 microbiologically confirmed episodes among 67 recipients (41%), and 191 separate species isolations were performed. Over 50% of the infected patients underwent two or more infectious episodes. Two classification decision tree models were created. The following features were enabled to differentiate the groups with single or recurrent infections: the duration of cold ischaemia, the post-transplant hospitalization period, the cause of chronic kidney disease and pathogens. The post-transplant hospitalization period and the length of cold ischaemia appear to be the principal parameters differentiating the subpopulations analysed. These coexisting factors, connected with recurrent infections in kidney transplant recipients, resemble a network which requires an advanced analysis to support the traditional statistics.

    Infection is a common complication of solid organ transplantation. It is associated with an increased risk of acute cellular rejection and loss of graft function. The most common infections are due to bacteria and viruses, including transmission of cytomegalovirus from donor to recipient. In the past years, an increasing number of parasitic infections have been documented in transplant recipients. We describe the first reported case of intestinal Giardia lamblia transmission following simultaneous pancreas and kidney transplantation.

    The annual number of cases of kidney transplantation in the Russian Federation varies from 900 to 1000. The generally accepted method of operation is the heterotopic allotransplantation into one of the iliac region. Proper kidney recipient are psychologically "forgotten", often completely lost sight of postoperative monitoring, especially in the long term, but may remind of itself in extraordinary cases like ours.

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

    Chronic kidney disease is a major public health problem that is associated with increased risks of kidney disease progression, cardiovascular disease and death. Kidney transplantation remains the renal replacement therapy of choice for patients with end-stage kidney disease. Despite impressive strides in short-term allograft survival, there has been little improvement in long-term kidney graft survival, and rates of death with a functioning allograft remain high. Long-term safety profiles of existing immunosuppressive regimens point to a need for continued search for alternative agents. This overview discusses emerging evidence on a few promising therapeutic approaches, juxtaposes conflicting findings and highlights remaining knowledge gaps.

    Histological renal lesions observed after liver transplantation are complex, multifactorial, and interrelated. The aims of this study were to determine whether kidney lesions observed at five yr after liver transplantation can predict long-term kidney function. Ninety-nine liver transplant patients receiving calcineurin inhibitor (CNI)-based immunosuppression, who had undergone a kidney biopsy at 60±48 months post-transplant, were included in this follow-up study. Kidney biopsies were scored according to the Banff classification. Estimated glomerular filtration rate (eGFR) was assessed at last follow-up, that is, 109±48 months after liver transplantation. eGFR decreased from 92±33 mL/min at transplantation to 63±19 mL/min after six months, to 57±17 mL/min at the kidney biopsy, to 54±24 mL/min at last follow-up (p<0.0001). At last follow-up, only three patients required renal replacement therapy. After the kidney biopsy, 13 patients were converted from CNIs to mammalian target of rapamycin inhibitors, but no significant improvement in eGFR was observed after conversion. Elevated eGFR at six months post-transplant and a lower fibrous intimal thickening score (cv) observed at five yr post-transplant were the two independent predictive factors for eGFR≥60 mL/min at nine yr post-transplant. Long-term kidney function seems to be predicted by the kidney vascular lesions.

    Parainfluenza virus (PIV) can cause serious infections after hematopoietic stem cell or lung transplantation. Limited data exist about PIV infections after kidney transplantation. We describe an outbreak of PIV-3 in a transplant unit. During the outbreak, 45 patients were treated on the ward for postoperative care after kidney or simultaneous pancreas-kidney (SPK) transplantation. Overall, 29 patients were tested for respiratory viruses (12 patients with respiratory symptoms, 17 asymptomatic exposed patients) from nasopharyngeal swabs using polymerase chain reaction. PIV-3 infection was confirmed in 12 patients. One patient remained asymptomatic. In others, symptoms were mostly mild upper respiratory tract symptoms and subsided within a few days with symptomatic treatment. Two patients suffered from lower respiratory tract symptoms (dyspnea, hypoxemia, pulmonary infiltrates in chest computed tomography) and required supplemental oxygen. Four of six SPK patients and eight of 39 of kidney transplant patients were infected with PIV (p = 0.04). In patients with follow-up tests, PIV-3 shedding was still detected 11-16 days after diagnosis. Despite rapid isolation of symptomatic patients, PIV-3 findings were diagnosed within 24 days, and the outbreak ceased only after closing the transplant ward temporarily. In conclusion, PIV-3 infections early after kidney or SPK transplantation were mostly mild. PIV-3 easily infected immunosuppressed transplant recipients, with prolonged viral shedding.

    Full Text Available Introduction. Due to the ever-present lack of kidney transplant grafts, more and more organs obtained from the so-called “marginal donors” group are accepted, which can provide suboptimal effect of transplantation, depending on their characteristics and/or implantation techniques. Case report. We presented a case with successful variation of kidney position with modified approach of kidney transplantation from an infant to an adult female patient with normal postoperative recovery. Urethral anastomosis was performed without antireflux procedure and this has not led to the development of reflux disease at an early stage. Conclusion. The position of a pair of kidneys proved to be satisfactory despite the growth of the kidney to the expected size and relatively small pelvis. There were no problems with venous stasis and kidney function from the very beginning was good.

    Full Text Available Background/Aim. Multiple renal arteries (MRAs represent a surgical challenge by the difficulty in performing anastomoses, bleeding and stenosis. MRAs should be preserved and special attention should be paid to accessory polar arteries. All renal arteries (RAs must be reconstructed and prepared for safe anastomosis. The paper decribed the different techniques of vessel reconstruction during kidney transplantation including important steps within recovery of organs, preparation and implantation. Methods. In a 16-year period (1996-2012 of kidney transplantation in the Military Medical Academy, Belgrade, a total of 310 living donors and 44 human cadaver kidney transplantations were performed, of which 28 (8% kidneys had two or more RAs. Results. All the transplanted kidneys had immediate function. We repaired 20 cases of donor kidneys with 2 arteries, 4 cases with three RAs, one case with 4 RAs, one case with 4 RAs and renal vein reconstruction, one case with 3 arteries and additional polytetrafluoroethylene (PTFE graft reconstruction, one case with transected renal artery and reconstruction with 5 cm long deceased donor external iliac artery. There were no major complications and graft failure. At a minimum of 1-year follow-up, all the patients showed normal renal function. Conclusion. Donor kidney transplantation on a contralateral side and “end-to-end” anastomosis of the renal artery to the internal iliac artery (IIA is our standard procedure with satisfactory results. Renal artery reconstruction and anastomosis with IIA is a safe and highly efficient procedure and kidneys with MRAs are not contraindicated for transplantation. A surgical team should be fully competent to remove cadaveric abdominal organs to avoid accidental injuries of organs vessels.

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

    2014-07-01

    Full Text Available Background/Aims: Sclerostin is secreted by osteocytes. As a circulating inhibitor of the Wnt-signaling pathway it inhibits bone formation and contributes to the development of osteoporosis. Sclerostin levels are elevated in patients with chronic kidney disease and end-stage renal disease. Since data for patients after kidney transplantation are scarce, we have prospectively measured sclerostin levels before and during the first year after renal transplantation and have examined the association of sclerostin with parameters of bone mineral metabolism and with bone mineral density. Methods: Sclerostin levels were measured by ELISA in 42 consecutive renal transplant recipients before and at defined intervals in the first year after transplantation. Bone mineral density was measured by dual energy X-ray absorptiometry. Results: Pre-transplant serum sclerostin levels were elevated in all patients (61.8 ± 32.3 pmol/l, normal range 20-30 pmol/l. Within 15 days after transplantation and correlating with the improvement of renal function, sclerostin levels dropped to 21.0 ± 14.7 pmol/l and subsequently increased to 23.8 ± 14.9 and 28.0 ± 16.8 pmol/l after 6 and 12 months, respectively (PConclusions: The rapid reduction of elevated serum sclerostin levels shortly after kidney transplantation parallels the improvement of renal function, but contrasts with the more delayed improvement of hyperparathyroidism. The normalization of both hormones could contribute to improved bone health after renal transplantation.

    Full Text Available Joseph Olusesan Fadare1, Babatunde L Salako21Department of Medicine, Kogi State Specialist Hospital, Lokoja; 2Department of Medicine, University of Ibadan, Ibadan, NigeriaAbstract: Organ transplantation has become a life-saving procedure for many disease conditions hitherto considered incurable. Kidney transplantation, now the treatment of choice for end-stage renal disease, is the commonest solid organ transplantation carried out in the world at the moment and it is the only solid organ transplantation done in Nigeria. This procedure, in addition to prolonging lives, also provides better quality of life and is evaluated as cost-effective, because it makes more resources available to other sectors of the economy. Organ transplantation in general and kidney transplantation in particular are fraught with ethical issues and dilemmas worldwide. Some of the ethical issues arising in the setting of developing countries like Nigeria may differ from those in countries where this procedure is established. Informed consent of the donor and the recipient is a major requirement for both organ donation and transplantation. Regarding donation, the ethical issues may differ depending on the type of organ donation, ie, whether it is living-related, living-unrelated, cadaveric, or from brain-dead individuals. Commodification of organs is identified as an ethical dilemma, and arguments for and against this practice are put forward here. Confidentiality of donor information, fairness and equity in donor selection, and access to kidney transplantation when needed are also discussed. Finally, the issue of safety of organ harvesting for the donor and of the transplantation process itself, and the possible long-term consequences for both parties are investigated.Keywords: kidney transplantation, ethical issues, developing countries, Nigeria

    Manystudies have shown that kidney transplant recipients have a higher incidence of cancers when compared with general population. However, most data on the posttransplant malignancies (PTM) are derived from Western literature and large population-based studies are rare. There is also lack of information about the posttransplant cancer-specific mortality rate. We conducted a population-based study of 4895 kidney transplants between 1972 and 2011, with data from the Hong Kong Renal Registry. Patterns of cancer incidence and mortality in our kidney transplant recipients were compared with those of the general population using standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) respectively. With 40 246 person-years of follow-up, 299 PTM was diagnosed. The SIR of all cancers was 2.94 (female 3.58 and male 2.58). Non-Hodgkin lymphoma (NHL), kidney, and bladder cancers had the highest SIRs. The overall SMR was 2.3 (female 3.4 and male 1.7) and the highest SMR was NHL. The patterns of PTM differ among countries. Increases in cancer incidence can now translate into similar increases in cancer mortality. NHL is important in our kidney transplant recipients. Strategies in cancer screening in selected patient groups are needed to improve transplant outcomes.

    Purpose of review: P4 medicine denotes an evolving field of medicine encompassing predictive, preventive, personalized, and participatory medicine. Using the example of kidney allograft rejection because of donor-recipient incompatibility in human leukocyte antigens, this review outlines P4 medicine’s relevance to the various stages of the kidney transplant cycle. Sources of information: A search for English articles was conducted in Medline via OvidSP (up to August 18, 2016) using a combination of subject headings (MeSH) and free text in titles, abstracts, and author keywords for the concepts kidney transplantation and P4 medicine. The electronic database search was expanded further on particular subject headings. Findings: Available histocompatibility methods exemplify current applications of the predictive and preventive domains of P4 medicine in kidney transplant recipients’ care. Pharmacogenomics are discussed as means to facilitate personalized immunosuppression regimens and promotion of active patient participation as a means to improve adherence. Limitations: For simplicity, this review focuses on rejection. P4 medicine, however, should more broadly address health concerns in kidney transplant recipients, including competing outcomes such as infections, malignancies, and cardiovascular disease. This review highlights how biomarkers to evaluate these competing outcomes warrant validation and standardization prior to their incorporation into clinical practice. Implications: Consideration of all 4 domains of the P4 medicine framework when caring for and/or studying kidney transplant recipients has the potential of increasing therapeutic efficiency, minimizing adverse effects, decreasing health care costs, and maximizing wellness. Technologies to gauge immune competency, immunosuppression requirements, and early/reversible immune-mediated injuries are required to optimize kidney transplant care. PMID:28270929

    Objective: To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods: SD rats served as both donors and recipients. 4℃ sodium lactate Ringer's was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava (IVC) inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results: Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion: This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.

    Full Text Available We report the first case of Ramsay Hunt syndrome (RHS diagnosed after kidney transplantation in Korea. RHS is a disease caused by latent varicella-zoster characterized to involve geniculate ganglion of the seventh cranial nerve. Patients who have undergone kidney transplantation can be easily affected by viral infections because of their immune-compromised status. A 35-year-old man with hypertensive end-stage renal disease underwent kidney transplantation. Two months after surgery, the recipient was diagnosed with RHS and treated with antivirals and steroids. However, after using the antiviral agents for the recommended duration, facial paralysis occurred as a new presentation and he required further treatment. Otalgia and periauricular vesicles improved, but the facial palsy remained.

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

    Infections are an important cause of morbidity and mortality during kidney transplant. In areas where tuberculosis is not endemic, Mycobacteria other than tuberculosis (MOOT), also known as 'atypical' Mycobacteria, are more frequently involved in mycobacterial infections than M. tuberculosis. The incidence of MOOT infection in renal transplant recipients ranges from 0.16 to 0.38 percent. This low rate of reported incidence is, however, often due to delay in diagnosis and lack of therapeutic protocols. Further difficulty is caused by the interaction of antimycobacterial drugs with the post-transplant immunosuppressive regimen, necessitating close monitoring of plasma concentrations and careful dose modification. We present two cases of Mycobacterium Chelonae infection in kidney transplant recipients which differ in both clinical presentation and pharmacological approach.

    It is estimated that approximately 50% of males over 50 have benign prostatic hypertrophy (BPH). BPH is underappreciated in anuric patients with end stage renal disease, and failure of diagnosis in this population can lead to complications after kidney transplantation. A single-center retrospective review of male patients over 50 yr of age transplanted from January 1, 2010, until September 30, 2013, was performed. Outcomes assessed were as follows: graft survival, urinary retention, discharge with Foley catheter, and urinary tract infection (UTI). Of 147 patients, 17.0% were diagnosed with BPH before transplant, 19.0% received a BPH diagnosis after transplant, and 64% did not have BPH. Compared to those without BPH, a post-transplant BPH diagnosis was associated with urinary retention during the transplant admission (0% vs. 46.4%, p < 0.01), discharge with Foley catheter (0% vs. 21.4%, p < 0.01), readmission related to urinary retention (0% vs. 46.4%, p < 0.01), and UTI (18.0% vs. 64.3%, p < 0.01). Patients with prior diagnosis of BPH and on therapy had similar outcomes to those without BPH. Following kidney transplant, urinary tract complications are more common in patients with BPH; however, being on medical therapy prior to transplantation diminishes the incidence of these complications significantly. © 2015 John Wiley & Sons A/S.

    The gap between supply and demand in kidney transplantation has led to increased use of marginal kidneys; however, kidneys with acute kidney injury are often declined/discarded. To determine whether this policy is justified, we analyzed outcomes of donor kidneys with acute kidney injury (AKI) in a large UK cohort. A retrospective analysis of the UK Transplant Registry evaluated deceased donors between 2003 and 2013. Donors were classified as no AKI, or AKI stage 1-3 according to Acute Kidney Injury Network (AKIN) criteria. Relationship of AKI with delayed graft function/primary nonfunction (DGF/PNF), estimated glomerular filtration rate (eGFR), and graft-survival at 90 days and 1 year was analyzed. There were 11 219 kidneys (1869 [17%] with AKI) included. Graft failure at 1 year is greater for donors with AKI than for those without (graft survival 89% vs. 91%, p = 0.02; odds ratio (OR) 1.20 [95% confidence interval (CI): 1.03-1.41]). DGF rates increase with donor AKI stage (p kidneys (9% vs. 4%, p = 0.04) Analysis of association between AKI and recipient eGFR suggests a risk of inferior eGFR with AKI versus no AKI (p kidneys from donors with AKI. We conclude that AKI stage 1 or 2 kidneys should be used; however, caution is advised for AKI stage 3 donors.

    Introduction: One of the most important complications of post-transplant is rejection. Analyzing survival is one of the areas of medical prognosis and data mining, as an effective approach, has the capacity of analyzing and estimating outcomes in advance through discovering appropriate models among data. The present study aims at comparing the effectiveness of C5.0 algorithms, neural network and C&RTree to predict kidney transplant survival before transplant. Method: To detect factors effective in predicting transplant survival, information needs analysis was performed via a researcher-made questionnaire. A checklist was prepared and data of 513 kidney disease patient files were extracted from Sina Urology Research Center. Following CRISP methodology for data mining, IBM SPSS Modeler 14.2, C5.0, C&RTree algorithms and neural network were used. Results: Body Mass Index (BMI), cause of renal dysfunction and duration of dialysis were evaluated in all three models as the most effective factors in transplant survival. C5.0 algorithm with the highest validity (96.77%) was the first in estimating kidney transplant survival in patients followed by C&RTree (83.7%) and neural network (79.5%) models. Conclusion: Among the three models, C5.0 algorithm was the top model with high validity that confirms its strength in predicting survival. The most effective kidney transplant survival factors were detected in this study; therefore, duration of transplant survival (year) can be determined considering the regulations set for a new sample with specific characteristics.

    To explore the effect of donations after cardiac death (DCD) kidney transplant performed in northwest China and the measures for management of delayed graft function (DGF). In the period of 2011-2013, a total of 51 families of DCD donor gave their consent to organ donation by signing the informed consent with the help by a Red Cross Organization (ROC) coordinator, and 102 kidneys were retrieved by organ procurement organization (OPO) teams. Ninety-four operations of renal transplantation were carried out in our hospital. All the patients were followed-up and based on the occurrence of DGF after transplantation, they were divided into DGF group and non-DGF group for comparative studies. The success rate of donation after cardiac death was 29.3%, and the incidence of post-transplantation DGF was 27.7%. The 1-year human/kidney survival rate was 98.9%/95.7%. Within six months after the transplant, the values of eGFR in DGF group were significantly lower and serum creatinine significantly higher than those in non-DGF group (P0.05). The occurrence of DGF in LifePort mechanical perfusion cohorts was significantly lower than that in the simple cold preservation group (21.5% vs. 41.4%, Ptransplant is good despite a high incidence of early DGF, and we recommend the use of low-temperature mechanical perfusion for storage and transportation of DCD donor kidney.

    The transplanted kidney, lying heterotopically in the iliac fossa, is especially vulnerable to damage from blunt trauma, particularly compression by vehicle seatbelt. We present a case wherein a functioning renal allograft lying in the right iliac fossa was severely injured by seatbelt compression, resulting in significant functional compromise and eventual loss. The patient later underwent successful retransplantation with a second living donor kidney. Management of injured renal transplant recipients requires appreciation of mechanisms likely to cause damage to the graft, as well as familiarity with available treatment options, both surgical and nonsurgical. As functional life spans of renal allografts improve, this type of injury will most likely be encountered with increasing frequency.

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.

    Full Text Available The experience of horseshoe kidney transplant operations is significantly restricted. Transplant surgeons often refuse to use horseshoe kidney due to a number of serious abnormalities of vessels and upper urinary tract in these organs. However, the constant shortage of donor organs and an increase in patients on the waiting list for kidney transplantation make us reconsider our approach to the selection of donor organs. The aim of this work was to demonstrate our result of horseshoe kidney transplantation

    Objectives To report the clinical experiences of srmultaneous hepatorenal transplantation. Methods We performed simultaneous hepatorenal transplantation in one patient with liver cirrhosis of hepatitis B and uremia of chronic nephritis on February 1,1999 and one patient with liver cirrhosis of hepatitis B complicated by hepatorenal syndrome on March 12, 1999.The donors were heart arrest cases. Rapid multiple organ harvesting techniques and UW solution infusion in situ were used. Liver and kidney transplantation were orthotopic and ordinary methods, respectively. Immunosuppressive drugs consisted of cyclosporine, Cellcept, ALG and sortstso steroids. Lamividine was used os day 50 and day 40 postoparation, respectively. Results Both transplanted organs rapidly achieved normal function postoperation and the patients recovered well but suffered mild kidney rejection day 110 postopemtion in No 1 patient. In No 2 patient, acute renal function failure, mental symptoms, muscle spasm,cerebral artery thrombosis, inhalation poeumonia and chronic liver graft rejection ensured sequentially but were controlled.The patients have survived for more than nine and eight months, respectively, with normal life quality. Conclusions Combined hepatorenal transplant is a radical treatment method for liver and kidney function failure and requires more comprehensive techniques than isolated single organ transplantation.Preventing the recurrence of hepatitis B by oral lamividine may be a kdy to long-term survival.

    2008-05-01

    We are reporting the case of a 17-year-old girl with kidney transplant under immunosuppressive treatment. Evidences of transplant malfunction led to urinary cytology to rule out BKV infection. The smears showed the presence of koilocytes. Gynecologic examination revealed numerous condylomatous lesions in the vulva, vagina, and cervix. PAP smears showed cells with moderate to severe koilocytic dysplasia. PCR performed on material retrieved from both the smears showed HPV18 DNA sequences. Koilocytes have rarely been documented in urinary cytologic examination. Since post-transplant immunosuppressed patients are prone to develop florid and extensive HPV infections, urinary cytology may prove useful for routine search of cells with this virus cytopathic effect.

    The natural history and survival of children with fibrocystic liver-kidney disease undergoing solid organ transplantation have infrequently been described. We report outcomes in a cohort of US children with fibrocystic liver-kidney disease receiving solid organ transplants over 20 yr. Retrospective cohort study of pediatric transplant recipients with diagnoses of fibrocystic liver-kidney disease from 1/1990 to 3/2010, using data from the SRTR. Subjects were categorized by the first transplanted organ: LT, KT, or SLK. Primary outcomes were death, re-transplant, transplant of the alternate organ, or initiation of dialysis. Seven hundred and sixteen subjects were transplanted in this period. Median age at first transplant was 9.7 yr. Of the LT, 14 (19%) required a second liver transplant at median of 0.2 yr, and five (7%) required kidney transplant or dialysis at a median of 9.0 yr. Of the KT, 188 (31%) required a second kidney transplant or dialysis at a median of 5.9 yr. Twenty-nine (5%) subsequently received liver transplant at a median of 6.0 yr. Among patients in this registry, far more children underwent kidney than liver transplants. The risk of subsequently needing transplantation of an alternate organ was low.

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

    2012-01-01

    Background Although the immunosuppressant cyclosporine (CsA) is widely used after kidney transplantation over the long term, there is still no firm consensus on the best way to monitor of CsA blood levels. Objectives Cyclosporine (CsA) assay is critical for the management of renal transplant recipients due to inter– and intra–patient variation in CsA absorption and metabolism. Patients and Methods: In a retrospective cross sectional study, blood levels of CsA (through and 2 hours post dose) measured at least 5 times during 3 years post transplantation, in 7702 kidney transplant recipients from different transplant center of Tehran, IR Iran between 2008 and 2012. Cyclosporine absorption (CA) calculated C2/C0 ratio. Results CA had a significant correlation with allograft function (P = 0.000, r =.0.285), this correlation was stronger than its relationship with C0 and C2 blood levels (P = 0.000 and P = 0.000 as well as r = 0.033 and r = 0.090, respectively). In univariate analysis during different times after transplantation, C0 and C2 blood levels significantly decreased over three years follow up (P = 0.000), (P = 0.000); While, CA reversely increases over the time (P = 0.000). In linear regression model overall CA levels had correlation with lower age of recipient (P = 0.02), hypokalemia (P = 0.001), higher level of creatinine (P = 0.02) and triglyceride (P = 0.001). Conclusions The present study shows that CsA absorption changes trough the post-transplant time and appears to increases over time in long–term period after kidney transplantation. PMID:23573469

    In Mortal Peril, Professor Epstein is critical of the current, regulated system for organ donation and suggests that a market for organ tissue would better meet the needs of patients. In this response to Professor Epstein, Professor Laura Dooley and Dr. Robert Gaston pair their skills to attack Professor Epstein's analysis. As they have done on several other occasions, Professors Dooley and Gaston argue that the kidney donation and transplantation arena is fraught with racial inequity, and that Professor Epstein's proposal for a market in kidneys will exacerbate this inequity. The authors maintain that to prevent the poor from being excluded from transplants, the government plays a critical (if imperfect) role in the allocation of these scarce resources. Furthermore, government intervention is acceptable to correct past discrimination because there is scientific evidence that the disproportionate incidence of kidney failure in African Americans is related to the evolutionary pressures of slave trading and slavery. Professors Dooley and Gaston also defend their previous efforts to change the government system of allocation and characterize the government's willingness to adopt their recommendations as an appropriate response to scientific research rather than a governmental susceptibility to lobbying from special interest groups. Finally, the authors criticize Professor Epstein's argument that dialysis is a viable alternative to transplantation because there are significant differences in "quality of life, morbidity and survival." Professors Dooley and Gaston conclude that government intervention is necessary for maintaining the equity in kidney transplantation that a market system would not.

    2006-01-01

    Kidney transplantation in rats is an experimental model often used for the development of general microsurgical or transplantation techniques, for immunologic studies, and for analyzing transplant-associated long-term arterial blood-pressure changes. The aim of the present study was to analyze different surgical techniques of kidney transplantation in rats, with emphasis on minimizing surgical complications and establishing guidelines for their prevention and management. Complications were categorized into general (e.g., core body temperature drop, ischemic time) and surgically related vascular and urinary tract complications. In conclusion, a significant reduction of the complication rate in renal transplantation in rats can be achieved by placing the animal on a heating pad at an appropriate temperature. To reduce the risk of vascular thrombosis, ice-cold saline with heparin and careful flushing of the donor kidneys are recommended. Vascular complications can be avoided by performing "end-to-end" anastomosis techniques. The use of stents and cannulas in the urinary tract is associated with a high risk of urinary tract obstruction, and therefore is not recommended.

  17. Black markets, transplant kidneys and interpersonal coercion

    Science.gov (United States)

    Taylor, J S

    2006-01-01

    One of the most common arguments against legalising markets in human kidneys is that this would result in the widespread misuse that is present in the black market becoming more prevalent. In particular, it is argued that if such markets were to be legalised, this would lead to an increase in the number of people being coerced into selling their kidneys. Moreover, such coercion would occur even if markets in kidneys were regulated, for those subject to such coercion would not be able to avail themselves of the legal protections that regulation would afford them. Despite the initial plausibility of this argument, there are three reasons to reject it. Firstly, the advantages of legalising markets in human kidneys would probably outweigh its possible disadvantages. Secondly, if it is believed that no such coercion can ever be tolerated, markets in only those human kidneys that fail to do away with coercion should be condemned. Finally, if coercion is genuinely opposed, then legalising kidney markets should be supported rather than opposed, for more people would be coerced (ie, into not selling) were such markets to be prohibited.

  18. Transplantation of Horseshoe Kidney from Living, Genetically Unrelated Donor

    Directory of Open Access Journals (Sweden)

    Kazuro Kikkawa

    2015-01-01

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

    The aim of this study was to investigate the value of a contrast-enhanced 3D MR angiography in detecting postoperative vascular complications after kidney transplantation in comparison with digital subtraction angiography (DSA). Forty-one patients who underwent a kidney transplantation were examined with MR angiography and DSA. Contrast-enhanced MR angiography was performed as a dynamic measurement with one precontrast and three postcontrast measurements. Maximum intensity projection reconstructions were performed for all postcontrast data sets after DSA. The results were evaluated by two independent observers who were unaware of the DSA results. Twenty-three hemodynamically significant arterial stenoses were identified with DSA in the iliac arteries (n=7), the renal allograft arteries (n=12), and in their first branches (n=4). For a patient-based analysis the sensitivity and specificity, respectively, for observer 1 were 100 and 97%, and for observer 2, 100 and 93%. Respective data were 100 and 100% after a consensus evaluation by two observers. Complications involving the renal veins were detected in 2 cases and perfusion defects of the kidney parenchyma were detected in 4 cases. Contrast-enhanced MR angiography is a reliable method in identifying postoperative arterial stenoses after kidney transplantation. In addition, dynamic MR angiography can be helpful in detecting venous complications and perfusion defects in kidney allografts. (orig.)

    The efforts in the late 1940s to 1960s of two Parisian pioneers in kidney transplantation, René Kűss, a surgeon, and Jean Hamburger, a nephrologist, have largely been forgotten. Küss developed the operation that is basically unchanged today. Both groups initiated clinical transplant programs in January 1951, and both were among the first to carry out kidney transplantation (i) without immunosuppressive therapy, (ii) between living-related and unrelated donors, (iii) with organs from deceased donors, (iv) with irradiation and immunosuppressive drugs, and (v) with long-term survival. In the opinion of many, the French did not receive full credit for their work internationally. © IMechE 2015.

    2014-01-01

    Full Text Available There is a wide gap between organ supply and demand, which results in a very long waiting time for kidney transplantation and an increasing number of deaths of the patients while on the waiting list. These events have raised many ethical, moral and societal issues regarding organ donation, allocation and use of living donors through exploitation of the poor for the benefit of the wealthy. Success in the implementation of kidney transplantation programs in a country depends on various factors including the economic situation, religious approval, public views, medical expertise and existing legislation. The public attitude toward donation is pivotal in all transplantation programs; increasing the awareness of the leaders of religion is vital in this regard.

    Kidney transplantation has been advocated as a therapeutic option in lung recipients who develop end-stage renal disease (ESRD). This analysis outlines patterns of allograft survival following kidney transplantation in previous lung recipients (KAL). Data from the UNOS lung and kidney transplantation registries (1987-2013) were cross-linked to identify lung recipients who were subsequently listed for and/or underwent kidney transplantation. Time-dependent Cox models compared the survival rates in KAL patients with those waitlisted for renal transplantation who never received kidneys. Survival analyses compared outcomes between KAL patients and risk-matched recipients of primary, kidney-only transplantation with no history of lung transplantation (KTx). A total of 270 lung recipients subsequently underwent kidney transplantation (KAL). Regression models demonstrated a lower risk of post-listing mortality for KAL patients compared with 346 lung recipients on the kidney waitlist who never received kidneys (Ploss (Ploss, for KAL patients (P = .86). KAL patients enjoy a significant survival benefit compared with waitlisted lung recipients who do not receive kidneys. However, KAL patients do poorly compared with KTx patients. Decisions about KAL transplantation must be made on a case-by-case basis considering patient and donor factors. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Diagnostic imaging after renal transplantation is of high importance in the differential diagnosis of peri- and postoperative complications. Sonography with color duplex imaging is the method of choice in the diagnosis of acute transplant rejection. MRI is an additional method in the diagnosis of transplant dysfunktion especially in diagnosis of perirenal fluid collections. MR angiography and MR urography are noninvasive diagnostic modalities with the potential to replace angiography and pyelography. Angiography, complemented by carbon dioxide angiography, still is the gold standard in the diagnosis of transplant artery stenosis. (orig.)

    Full Text Available Background Dyslipidemia after kidney transplantation is a frequent finding and is multifactorial. Immunosuppressive agents such as cyclosporine (CsA can cause hypercholesterolemia. Objectives As there were few reports with conflicting evidence on whether CsA related dyslipidemia is dose related and that CsA monitoring assays (trough level, C0, or two hour post dose level, C2 is a better predictor for dyslipidemia development; hence, the current study, in a large sample size, was designed to answer these questions. 3. Patients and Methods In the current retrospective cross sectional study, 1391 kidney transplant recipients were enrolled. All patients received CsA plus mycophenolatemofetile or azathioprine and prednisolone. Serum creatinine, CsA blood levels and lipid profile were measured after 12-14 h fasting. Mann-Whitney and Kruskal-Wallis, Pearson`s test and logistic regression were used for data analyses. Results Mean age of 1391studied population was 38.7 ± 15 years old. Hypercholesterolemia and hypertriglyceridemia were observed in 58.9% and 86.6%, respectively and they were more significantly detected in cadaveric kidney transplantation. Dyslipidemia had weak correlation with age of recipient, serum creatinine, C0 and C2 levels of CsA. At logistic regression, serum creatinine was the only risk factor for hypercholesterolemia development after kidney transplantation (OR = 1.6, CI 95%: 1.4 -1.8. Conclusions Dyslipidemia is a common finding after kidney transplantation and has no correlation with CsA level. According to conflicting data on the precise effect of different factors in inducing dyslipidemia, prospective large sample size studies should consider better control of dyslipidemia.

    Paricalcitol, a selective vitamin D receptor activator, is used to treat secondary hyperparathyroidism in kidney transplant patients. Experimental and clinical studies in non-transplant kidney disease patients have found this molecule to have anti-inflammatory properties. In this exploratory study, we evaluated the anti-inflammatory profile of paricalcitol in kidney-transplant recipients. Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1μg/day). Serum concentrations and gene expression levels of inflammatory cytokines in peripheral blood mononuclear cells were analysed at the beginning and end of the study. Paricalcitol significantly decreased parathyroid hormone levels with no changes in calcium and phosphorous. It also reduced serum concentrations of interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) by 29% (P<0.05) and 9.5% (P<0.05) compared to baseline, respectively. Furthermore, gene expression levels of IL-6 and TNF-α in peripheral blood mononuclear cells decreased by 14.1% (P<0.001) and 34.1% (P<0.001), respectively. The ratios between pro-inflammatory cytokines (TNF-α and IL-6) and anti-inflammatory cytokines (IL-10), both regarding serum concentrations and gene expression, also experienced a significant reduction. Paricalcitol administration to kidney transplant recipients has been found to have beneficial effects on inflammation, which may be associated with potential clinical benefits.

  6. Forgotten indwelling stent in a transplanted kidney: a case report

    Science.gov (United States)

    2009-01-01

    • Introduction Forgotten or retained ureteric stents are a well-recognised phenomenon with the potential to cause a range of complications, the most dangerous of which is obstructive nephropathy. These risks are potentially devastating when the patient has a single functioning transplanted kidney. Here we describe the case of a renal transplantation patient with a forgotten ureteric stent of 10 years, who presented with irritative bladder symptoms and was successfully managed using a multimodal urological approach with specialist advice on antibiotic prophylaxis. To the best of our knowledge this is the longest documented time period for a forgotten ureteric stent in a transplantation patient and is unusual in that obstructive nephropathy did not occur. • Case presentation A 32-year-old man with a history of end stage renal failure of unknown aetiology received a cadaveric renal transplant in 1995. An indwelling JJ stent was placed at the time of transplant to protect the vesicoureteric anastomosis. The patient made an unremarkable recovery and initially attended regular follow up in the renal transplant clinic. He was subsequently lost to transplant clinic follow up. In 2005 at the age of 42 he was referred to a nephrologist with irritative bladder symptoms. Renal tract imaging with ultrasound and a plain film demonstrated a retained encrusted ureteric stent. • Conclusion The removal of a retained encrusted ureteric stent always provides a urological challenge. This case demonstrates that multimodal treatment involving a combination of endourological and percutaneous techniques can be employed with success even when the patient has a heavily encrusted stent for a single functioning transplanted kidney. Involvement of a microbiologist to advise on prophylactic antibiotics is deemed especially useful, as the immunosuppressed transplant patient is at particular risk of sepsis secondary to bacteraemia as a result of the endoscopic manipulation of the colonised

    The ability of a transplant recipient to accept a graft depends on the ability of immunosuppressive drugs to regulate the immune system. Such treatments have been associated with tumor promotion and progression. A systematic literature review was carried out. Electronic searches were performed in PubMed database. The searching criterion was "urological tumors in kidney transplant recipients". The most important issues regarding incidence, urological tumor-specific features, and relevant ones about the treatment are summarized. In renal transplant, 15% of all tumors are urological neoplasias; furthermore, they are the leading neoplastic cause of death. In transplant population the incidence rate of renal cell carcinoma (RCC), transitional cell bladder carcinoma (TCBC), testicular carcinoma (TC) and prostate cancer are increased 15, 3, 3 and 2 times respectively. Treatments used in transplant patients are similar to those employed in the general population:radical nephrectomy for the native kidney and conservative surgery for the graft are indicated for RCC. Radical prostatectomy is technically feasible for localized PC.Regarding to transitional cell carcinoma BCG or MMC is not contraindicated. The incidence rate of cancer has increased among transplant population. These tumors can be managed following the same criteria than in general population. Because in this population the prognosis is worse for the immunosuppression, closer monitoring is required. Copyright © 2014 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    We present a case of ocular syphilis after a renal transplantation involving progressive vision loss without clinically identifiable ocular disease. Electroretinography showed signs of ischemia, especially in the internal retina. A serological test was positive for syphilis. Lumbar puncture revealed lymphocytic meningitis and a positive serologic test for syphilis in the cerebrospinal fluid. The patient was treated with penicillin, and had a quick vision improvement. In the case of transplant recipients, clinicians should always consider the diagnosis of ocular syphilis in cases with unexplained visual acuity decrement, as this condition may cause serious complications if not treated.

    Half of the recovered expanded criteria donor (ECD) kidneys are discarded in the United States. A new kidney allocation system offers kidneys at higher risk of discard, Kidney Donor Profile Index (KDPI)>85%, to a wider geographic area to promote broader sharing and expedite utilization. Dual kidney transplantation (DKT) based on the KDPI is a potential option to streamline allocation of kidneys which otherwise would have been discarded. To assess the clinical utility of the KDPI in kidneys at higher risk of discard, we analyzed the OPTN/UNOS Registry that included the deceased donor kidneys recovered between 2002 and 2012. The primary outcomes were allograft survival, patient survival and discard rate based on different KDPI categories (90%). Kidneys with KDPI>90% were associated with increased odds of discard (OR=1.99, 95% CI 1.74-2.29) compared to ones with KDPI90% were associated with lower overall allograft failure (HR=0.74, 95% CI 0.62-0.89) and better patient survival (HR=0.79, 95% CI 0.64-0.98) compared to single ECD kidneys with KDPI>90%. Kidneys at higher risk of discard may be offered in the up-front allocation system as a DKT. Further modeling and simulation studies are required to determine a reasonable KDPI cutoff percentile.

    The aim of this study was to investigate quantitative cytologic changes in oral mucosal smears collected from kidney transplant patients by modern stereologic methods. We enrolled 32 kidney transplant patients. Smears were obtained from the buccal mucosa transplant patients before and 12 months after kidney transplantation. Smears from each individual were stained using the Papanicolaou method and were analyzed using a stereological method. Statistically, the nuclear volumes and cytoplasmic volumes in the cells of buccal mucosa were markedly higher after kidney transplantation (P < .05). There was a decreased positive cell density in the oral epithelial cells after kidney transplantation compared with before renal transplantation (P < .05). These findings suggest that there are alterations in the oral epithelial cells after kidney transplantation, which are detectable by microscopy and cytomorphometry. Copyright © 2015 Elsevier Inc.

  12. THE ROLE OF PRE-TRANSPLANT AND DE NOVO ALLOANTIBODIES IN KIDNEY TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Kidney transplant recipients may have pre-transplant alloantibodies or develop de novo anti-HLA and non- HLA antibodies after transplantation. Although these antibodies may be donor-specific or non-donor-specific, their presence may increase the risk for acute and chronic rejection, thereby decreasing allograft survival. The introduction of high sensitive and specific methods to detect anti-HLA antibodies, both before and after trans- plantation, will help to define transplant recipients who might be at increased risk for early or late allograft failure. Moreover, knowledge of alloantibody status before transplantation may help to guide the appropriate use of immunomodulatory agents and plasmapheresis to remove anti-HLA antibodies or downregulate their production. The review focuses on the associations between renal graft outcome and pre-transplant and de novo alloantibodies.

    There have been few studies of patients with renal allografts functioning for more than 20 years. We sought to identify clinical factors associated with ultra long-term (>20 year) renal allograft survival and to describe the clinical features of these patients. We performed a retrospective analysis of the Irish Renal Transplant Database and included 1174 transplants in 1002 patients. There were 255 (21.74%) patients with graft function for 20 years or more. Multivariate analysis identified recipient age (HR 1.01, CI 1.01-1.02), gender (male HR 1.25, CI 1.08-1.45), acute rejection (HR 1.26, CI 1.09-1.45) and transplant type (living related donor vs. deceased donor) (HR 0.52, CI 0.40-0.66) as significantly associated with long-term graft loss. Median serum creatinine was 115 μmol\\/L. The 5-year graft survival in 20-year survivors was 74.7%. The mean age at death was 62.7 years (±10.6). The most common causes of death were cardiovascular disease and malignancy. The two major causes of graft loss were death (with function) and interstitial fibrosis\\/tubular atrophy. Comorbidities included skin cancer (36.1%), coronary heart disease (17.3%) and other malignancies (14.5%). This study identifies factors associated with long-term allograft survival and a high rate of morbidity and early mortality in long-term transplant recipients.

  14. Evaluation and Management of Proteinuria After Kidney Transplantation.

    2015-10-01

    Proteinuria occurs commonly after kidney transplantation. Because there are no specific guidelines for defining and detecting proteinuria in transplant recipients, its prevalence can vary depending on the methods used. Most often, the same cutoffs for defining proteinuria in the nontransplant population are applied. There are several risk factors for proteinuria, including some transplant-specific diagnoses and immunosuppressive medications. Posttransplantation proteinuria is associated with reduced graft survival as well as an increased risk of cardiovascular events and death. Treatments to decrease proteinuria have been based on blocking the renin-angiotensin-aldosterone system with the use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. This review describes the measurement, prevalence, etiology, prognostic significance, and management of proteinuria in both adult and pediatric transplant recipients.

    Cancer is a major cause of morbidity among those with kidney transplants. Farrugia et al. examined the overall and site-specific risk of cancer death among kidney transplant recipients. Cancer outcomes, particularly for those with a history of cancer prior to transplantation, are poor. The overall risk of death attributed to cancer in patients with kidney transplants is increased at least tenfold over that in cancer patients in the general population.

    3 patients with renal transplantation who developed polycythemia presented normalization of the hemoglobin levels immediately after nephrectomy of the native kidneys. This observation induced the authors to study the role of the native kidneys in the genesis of polycythemia in recipients of renal allografts. Comparison was made among 32 patients submitted to renal transplantation, with maintenance of native kidneys (group I) and among 31 under the same conditions, but without the native kidneys (group II). Both groups were comparable according to age, sex, rejection crisis incidence and immunosuppressive therapy. It was observed that the hemoglobin levels of group I were significantly higher (p less than 0.05 to p less than 0.005) than those observed in group II, from the 3rd to the 30th posttransplantation month, becoming comparable from the 36th to the 54th months. The hemoglobin production, measured by the kinetics of labeled iron (59Fe), was higher in patients of group I. The authors concluded that the native kidneys are responsible for the observed polycythemia after a kidney transplantation.

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

    Full Text Available Background: The purpose of this study was to characterize the pharmacokinetic parameters of mycophenolic acid (MPA in Iranian kidney transplant patients. Methods: Plasma MPA concentration of mycophenolate mofetile (MMF 1 gram two times a day was measured in 21 Iranian kidney transplant recipients receiving treatment. Patients who entered the study had been transplanted for more than 3 months and their drug level was supposed to be at steady state. MMF concentration was measured with high-performance liquid chromatography (HPLC. Results: The plasma MPA concentration-time curve was characterized by an early sharp peak at about 1 hour postdose. The mean Area Under Curve (AUC, Cmax and Tmax were 47.0±18.3 µg.h/ml, 18.6±8.5 µg/ml and 1.0±0.5 hours respectively. Conclusion: The plasma MPA concentration-time curve pattern of Iranian patients was similar and consistent with previously reported profiles in other populations taking the same dose.

    International surveys have shown that the leading cause of death after kidney transplantation has cardiovascular origin with a prevalence of 35-40%. As a preventive strategy these patients receive aspirin (ASA) therapy, even though their rate of aspirin resistance is still unknown. In our study, platelet aggregation measurements were performed between 2009 and 2012 investigating the laboratory effect of low-dose aspirin (100 mg) treatment using a CARAT TX4 optical aggregometer. ASA therapy was considered clinically effective in case of low ( i.e., below 40%) epinephrine-induced (10 μM) platelet aggregation index. Rate of aspirin resistance, morbidity and mortality data of kidney transplanted patients (n = 255, mean age: 49 ± 12 years) were compared to a patient population with cardio- and cerebrovascular diseases (n = 346, mean age: 52.6 ± 11 years). Rate of aspirin resistance was significantly higher in the renal transplantation group (RT) compared to the positive control group (PC) (35.9% vs. 25.6%, p aspirin resistance contributes to the high cardiovascular mortality after kidney transplantation.

    The recent availability of cinacalcet has provided a possible alternative to parathyroidectomy in kidney transplant patients with persistent hyperparathyroidism, but its effect on bone mass density (BMD) is unknown. From our database containing 163 kidney transplants performed at our center from 1999-2007, we compared recipients who received cinacalcet for persistent hypercalcemia and hyperparathyroidism following renal tx (n=8; CIN) with up to 2 other post tx patients matched for age, sex, race, and graft function (n=15; CON). The outcome of the study was BMD changes from baseline to 12, 24, and 36 months post renal tx. Repeated Measures Mixed model was used to assess the difference of BMD change between two groups. Cinacalcet therapy was started at a median of 9 months (range; 1, 24 months) post tx with a mean dose 56±29 mg/d (mean duration; 1.6 years, range; 1, 2.1). Cinacalcet therapy was associated with significant reduction of serum calcium compared to control. Cinacalcet therapy was associated with greater BMD increase at the hip over the 36-month post transplant period. Cinacalcet was well tolerated. Our results suggest that cinacalcet may have a small but favorable effect on bone density following kidney transplantation. PMID:21094814

  2. The Critically Ill Kidney Transplant Recipient: A Narrative Review.

    2016-06-01

    Kidney transplantation is the most common solid organ transplantation performed worldwide. Up to 6% of kidney transplant recipients experience a life-threatening complication that requires ICU admission, chiefly in the late posttransplantation period (≥ 6 months). Acute respiratory failure and septic shock are the main reasons for ICU admission. Cardiac pulmonary edema, bacterial pneumonia, acute graft pyelonephritis, and bloodstream infections account for the vast majority of diagnoses in the ICU. Pneumocystis jirovecii pneumonia is the most common opportunistic infection, and one-half of the patients so infected require mechanical ventilation. The incidence of cytomegalovirus visceral infections in the era of preemptive therapy has dramatically decreased. Drug-related neutropenia, sirolimus-related pneumonitis, and posterior reversible encephalopathy syndrome are among the most common immunosuppression-associated toxic effects. Importantly, the impact of critical illness on graft function is worrisome. Throughout the ICU stay, acute kidney injury is common, and about 40% of the recipients require renal replacement therapy. One-half of the patients are discharged alive and free from dialysis. Hospital mortality can reach 30% and correlates with acute illness severity and reason for ICU admission. Transplant characteristics are not predictors of short-term survival. Graft survival depends on pre-ICU graft function, disease severity, and renal toxicity of ICU investigations and treatments.

    Full Text Available Muslims with renal transplant often ask their doctors whether fasting Ramadan is safe. Scanty studies have addressed this question. This prospective study was undertaken to identify any clinical or biological changes with Muslim fasting. 22 kidney transplant patients with stable kidney functions, who were transplanted for more than one year, and voluntarily chose to fast during Ramadan in 1425 H (October-November 2004, were studied. Total of 22 subjects (10 men and 12 women with a mean age of 47 ± 11.6 years were studied. Full clinical and biological assessment was done before during and after the month of Ramadan fasting. Medications were taken in two divided doses at sunset (time of breaking the fast and pre dawn (before the fast. None of the patients experienced any undue fatigue, or symptoms. Body weight, blood pressure, kidney function tests, blood sugar, lipid profile, and cyclosporine levels remained stable. In conclusion it is safe for renal transplant recipients of more than one year and having stable graft function to fast during the month of Ramadan; however caution is advised for moderate to severe impaired renal function.

    Hemolytic anemia and pure red cell aplasia (PRCA) after allogeneic hematopoietic stem cell transplantation (HSCT) have been reported to be mainly related to ABO-incompatibility between donor and recipient. Autoimmune hemolytic anemia (AIHA) without ABO-incompatibility has been also reported after allogeneic HSCT, especially with T-cell depletion. However, optimal management of AIHA or PRCA remains unclear. A 54-year-old male with myelodysplastic syndrome (MDS) underwent haploidentical human leukocyte antigen-mismatched HSCT using in vivo alemtuzumab and developed AIHA and PRCA simultaneously 15 months after transplantation, following the administration of cidofovir and probenecid for persistent cytomegalovirus (CMV) antigenemia and retinitis. AIHA was successfully treated with rituximab, and subsequently PRCA with cyclosporine without relapse of MDS or recurrence of CMV infection. The clinical course suggested that AIHA was mainly caused by humoral immune response, while PRCA was mainly caused by cell-mediated immune response in this patient, although these immune responses might be related to each other.

    Background Kidney transplantation corrects or improves many complications of chronic kidney disease, but its impact on disordered mineral metabolism is incompletely understood. Methods We performed a multicenter, prospective, observational cohort study of 246 kidney transplant recipients in the United States to investigate the evolution of mineral metabolism from pretransplant through the first year after transplantation. Participants were enrolled into 2 strata defined by their pretransplant levels of parathyroid hormone (PTH), low PTH (>65 to ≤300 pg/mL; n = 112), and high PTH (>300 pg/mL; n = 134) and underwent repeated, longitudinal testing for mineral metabolites. Results The prevalence of posttransplant, persistent hyperparathyroidism (PTH >65 pg/mL) was 89.5%, 86.8%, 83.1%, and 86.2%, at months 3, 6, 9, and 12, respectively, among participants who remained untreated with cinacalcet, vitamin D sterols, or parathyroidectomy. The results did not differ across the low and high PTH strata, and rates of persistent hyperparathyroidism remained higher than 40% when defined using a higher PTH threshold greater than 130 pg/mL. Rates of hypercalcemia peaked at 48% at week 8 in the high PTH stratum and then steadily decreased through month 12. Rates of hypophosphatemia (<2.5 mg/dL) peaked at week 2 and then progressively decreased through month 12. Levels of intact fibroblast growth factor 23 decreased rapidly during the first 3 months after transplantation in both PTH strata and remained less than 40 pg/mL thereafter. Conclusions Persistent hyperparathyroidism is common after kidney transplantation. Further studies should determine if persistent hyperparathyroidism or its treatment influences long-term posttransplantation clinical outcomes. PMID:26177089

    Aim: To evaluate the potential application of microbubble agents in the immediate post-transplant period, by studying contrast uptake and washout, and to correlate these values with clinical indices, and thus, assess the potential prognostic value of this technique. Materials and methods: The study group comprised 20 consecutive renal transplant patients within 7 days of transplantation. Sonovue was administered as an intravenous bolus with continuous imaging of the transplant kidney at low mechanical index (MI) for 1 min post-injection. These data were analysed off-line by two observers, and time intensity curves (TIC) for the upper, mid, and lower poles constructed. Within each pole, a region of interest (5 mm square) was placed over the cortex, medullary pyramid, and interlobar artery, resulting in a total of nine TIC for each patient. TIC parameters included the arrival time (AT), time to peak (TTP), peak intensity (Max), gradient of the slope (M), and the area under curve (AUC). Results: For both observers there was good agreement for all values measured from the cortex and medulla, but poor interobserver correlation for the vascular values. In addition, there was only agreement for these values in the upper and mid-pole of the transplant with poor agreement for the lower pole values. The mid-pole of the transplant kidney was chosen as the point of measurement for subsequent studies. Mid-pole values were correlated with clinical data and outcome over the 3-month post-transplant period. Renal microbubble perfusion correlated with the transplant estimated glomerular filtration rate (eGFR) at 3 months post-transplantation (p = 0.016). Discussion: In conclusion, this is the first study to confirm reproducibility of the Sonovue TIC data in transplant patients and to quantify regional variation and perfusion. The statistically significant estimates of transplant perfusion may be of future benefit to transplant recipients and potentially utilized as a prognostic tool

    Full Text Available OBJECTIVES: To evaluate the prevalence of cholecystopathy in chronic renal patients awaiting kidney transplants. INTRODUCTION: The prevalence and management of cholelithiasis in renal transplant patients is not well established. METHODS: A total of 342 chronic renal failure patients on the waiting list for a kidney transplant were studied. Patients were evaluated for the presence of cholelithiasis and related symptoms, previous cholecystectomies and other abdominal surgeries, time on dialysis, and general data (gender, age, number of pregnancies, and body mass index. RESULTS: Cholelithiasis was found in 41 out of 342 patients (12%. Twelve of these patients, all symptomatic, had previously undergone cholecystectomies. Five out of 29 patients who had not undergone surgery were symptomatic. Overall, 17 patients (41.5% were symptomatic. Their mean age was 54 (range 32-74 years old; 61% were female, and their mean body mass index was 25.4. Nineteen (76% out of 25 women had previously been pregnant, with an average of 3.6 pregnancies per woman. CONCLUSIONS: The frequency of cholelithiasis was similar to that reported in the literature for the general population. However, the high frequency of symptomatic patients points toward an indication of routine pre-transplant cholecystectomy to avoid serious post-transplant complications.

    Lack of an accepted definition for 'high immunological risk' hampers individualization of immunosuppressive therapy after kidney transplantation. For recipient-related risk factors for acute rejection, the most compelling evidence points to younger age and African American ethnicity. Recipient gender, body mass, previous transplantation, and concomitant infection or disease do not appear to be influential. Deceased donation now has only a minor effect on rejection risk, but older donor age remains a significant predictor. Conventional immunological markers (human leukocyte antigen [HLA] mismatching, pretransplant anti-HLA alloantibodies, and panel reactive antibodies) are being reassessed in light of growing understanding about the role of donor-specific antibodies (DSA). At the time of transplant, delayed graft function is one of the most clear-cut risk factors for acute rejection. Extended cold ischemia time (≥ 24 h) may also play a contributory role. While it is not yet possible to establish conclusively the relative contribution of different risk factors for acute rejection after kidney transplantation, the available data point to variables that should be taken into account at the time of transplant. Together, these offer a realistic basis for planning an appropriate immunosuppression regimen in individual patients.

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

    Limited number of publications described vaginal microflora after kidney transplantation. Our PubMed search revealed only 18 publications including words "vaginal bacteria & kidney transplant" in the period of 1978-2011. The aim of this study was to characterize lactobacilli isolated from vaginal swabs of women after kidney transplantation, compared with healthy women. Eighteen renal transplant recipients (mean age 36.1) and 20 healthy women (mean age 36.0) were evaluated. Lactobacilli were cultured on MRS and Columbia blood agars. Biochemical identification with API 50 CHL (bioMerieux, Marcy L'Etoile, France) and multiplex PCR according to Song et al. was performed. Lactobacilli were tested for production of H(2)O(2). Minimal inhibitory concentrations (MICs) of selected antimicrobial agents were determined with E-tests (bioMerieux, Marcy L'Etoile, France) and interpreted with CLSI and EUCAST criteria. No bacterial vaginosis was found among studied women. Two strains of group I were identified as Lactobacillus delbrueckii; 18 strains as Lactobacillus gasseri and 15 strains as Lactobacillus crispatus. Only 3 strains from group II were not identified by species-specific mPCR. Group IV was represented with 2 unidentified strains. Vaginal lactobacilli isolated from healthy women represented more homogenous group compared with heterogenous renal transplant recipients. Biochemical identification of lactobacilli by API 50 CHL kits was concordant with mPCR results only in 7 cases (17.5%), all 7 strains were identified as L. crispatus. Majority (93%) of lactobacilli were H(2)O(2) producers. All isolated lactobacilli (100%) demonstrated high resistance to metronidazole (MIC > 256 μg/ml). Only 2 strains resistant to vancomycin (MICs: 32 and 256 μg/ml respectively), in the study and control group, and one to moxifloxacin (MIC = 32 μg/ml), were found. Resistance to metronidazole and vancomycin was concordant in CLSI and EUCAST (2010) criteria. Although significant

  12. Statins in chronic kidney disease and kidney transplantation.

    2014-10-01

    HMG-CoA reductase inhibitors (statins) have been shown to improve cardiovascular (CV) outcomes in the general population as well as in patients with cardiovascular disease (CVD). Statins' beneficial effects have been attributed to both cholesterol-lowering and cholesterol-independent "pleiotropic" properties. By their pleiotropic effects statins have been shown to reduce inflammation, alleviate oxidative stress, modify the immunologic responses, improve endothelial function and suppress platelet aggregation. Patients with chronic kidney disease (CKD) exhibit an enormous increase in CVD rates even from early CKD stages. As considerable differences exist in dyslipidemia characteristics and the pathogenesis of CVD in CKD, statins' CV benefits in CKD patients (including those with a kidney graft) should not be considered unequivocal. Indeed, accumulating clinical evidence suggests that statins exert diverse effects on dialysis and non-dialysis CKD patients. Therefore, it seems that statins improve CV outcomes in non-dialysis patients whereas exert little (if any) benefit in the dialysis population. It has also been proposed that dyslipidemia might play a causative role or even accelerate renal injury. Moreover, ample experimental evidence suggests that statins ameliorate renal damage. However, a high quality randomized controlled trial (RCT) and metaanalyses do not support a beneficial role of statins in renal outcomes in terms of proteinuria reduction or retardation of glomerular filtration rate (GFR) decline.

    During the last decades, the disparity between the organ supply and the demand for kidney transplantation in Europe has led to consider living donors as a more acceptable option. In the last 7 years, we have established an interdisciplinary supporting transplant team to increase the rate of living donation. After 2001, the new interdisciplinary transplant team consisted of a transplant surgeon, a nephrologist, a pediatrician, a radiologist, a psychologist, a transplant coordinator, and a transplant nurse. We performed a prospective analysis to examine the effect of implementing this team on our living donation program. Demographic data, the annual number of procedures, the duration of waiting, and the cold ischemia time were evaluated among brain-dead and living donors. From January 2002 until December 2008, the number of patients who were annually on the waiting list increased 42% (from 377 to 536 patients). Consequently, the number of the total kidney transplants increased from 81 to 120 with an annual median of 98 cases. By implementing the interdisciplinary transplant team, a significant increase of living kidney donors was observed: from 18 to 42 cases; median = 27). In the last 7 years, a total number of 796 kidney transplants have been performed: 567 from brain-dead and 229 from living donors. In 2001, the waiting list times for recipients who received grafts from brain-dead versus living donors were 1356 versus 615 days respectively. Compared with 2008, the duration on the waiting list decreased significantly for patients receiving a living donor graft, whereas there was a slight increase for the patients in the brain-dead group: brain death versus living donors: 1407 versus 305 days. The interdisciplinary approach has also reduced the cold ischemia time for the living donor recipients: 3 hours and 42 minutes in 2001 versus 2 hours and 50 minutes in 2008. During the last years, by implementing an interdisciplinary transplant team, supporting living donor

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

    Longest bipolar length of the kidney graft is routinely measured for ultrasonographic assessment of graft size (GS), although the value of the graft length remains unclear. In a single-center, observational study involving 319 deceased-donor kidney transplant recipients, we assessed variations in absolute and adjusted GS (corrected for body surface area) between 1 and 12 months after transplantation ([INCREMENT]GS1m→12m). We tested whether variations in GS during the first year were predictive of the composite outcome of a reduction of 50% or more in the estimated glomerular filtration rate or end-stage graft failure. At 1 year after transplantation, 121 patients (38%) had a decrease in GS ([INCREMENT]GS1m→12m decrease in GS reached the composite outcome as compared with 12 patients with an increase in GS (34% and 6%, respectively; P decrease in GS during the first year after transplantation (hazard ratio, 4.55; 95% CI, 2.35-8.81; P decrease in kidney GS during the first year after transplantation, as compared with an increase in GS, is a powerful predictor of subsequent graft dysfunction or end-stage graft failure.

    Jehovah's Witness refuse blood transfusion, but they accept organ transplantation, albumin, immunoglobulin, vaccines and clotting factors. We present 3 kidney transplants in Jehovah's Witness patients (two male and one female) without blood transfusion, with a mean age of 31.33 years and a mean body mass index of 20.99 kg/m(2). All patients underwent pretransplant peritoneal dialysis for an average of 52.3 months. Two transplants came from living donors and one from a deceased donor with a cold ischemia of 23 hours. The donors were two females and one male, with a mean age of 34.33 years. All patients received pretransplant erythropoietin and iron dextran and an intraoperative cell saver was used. Hemoglobin, hematocrit, red blood cells and serum creatinine levels, as well as the glomerular filtration at 24 months postransplant were stable. All patients received induction with basiliximab and initial immunosuppression with calcineurin inhibitors. One of the patients had a perirenal hematoma as a complication, which required a surgery 20 days post-transplant. At 5, 26 and 36 months postransplant the three patients are alive and with functional grafts. It is possible to perform kidney transplantation without transfusion in Jehovah's Witness, obtaining an acceptable global survival without acute rejection.

    The evolution of transplantation entails multiple complications, whose frequency and severity depend on the conditions of sampling and the quality of conservation, the grafting technique, the immunosuppressant treatment and the quality of surveillance. The latter has been significantly improved by the progress of imaging, which has allowed improving the prognosis of renal transplantation. Imaging is used for the diagnosis, surveillance and, in some cases, the treatment of these complications. Among the modern imaging techniques, color Doppler is a non-aggressive technique which currently ranks first for the screening of pedicular and peripheral vascular complications. The role of MRI is still ill-defined. While the initial results demonstrated its poor specificity, the use of paramagnetic contrast media provides a remarkable diagnostic effectiveness in case of peripheral necrosis. The lack of diagnostic specificity of imaging for medical complications most often confines its use to the follow-up of evolution. Thus renal biopsy remains the key examination for the diagnosis of immunological, ischemic or toxic complications. Ultrasound plays an essential part in the screening of urological complications, for which the diagnosis and assessment are based on plain radiological examinations. The indications of CT, which are defined according to ultrasound findings, are limited to the study of postoperative fluid collections and infectious complications. Arteriography remains essential for some selected indications, such as the study of the vascular pedicle. Intraoperative radiology plays an important part in the diagnosis and treatment of urological complications, the treatment of arterial stenoses and the drainage of some postoperative fluid collections. 34 figs.

    This study examined the relations between appraisal of transplant-related stressors, coping, and adjustment dimensions following kidney transplantation (KT). Two models were tested: (1) the main effects model proposing that stress appraisal and coping strategies are directly associated with adjustment dimensions; and (2) the moderating model of stress proposing that each coping strategy interacts with stress appraisal. Importantly, there is a lack of research examining the two models simultaneously among recipients of solid organ transplantation. A total of 174 KT recipients completed the questionnaires. Predictors of post-transplant adjustment included appraisal of transplant-related stressors and coping strategies (task-, emotion-, and avoidance-focused). Adjustment dimensions were psychological distress, worries about the transplant, feelings of guilt, fear of disclosure of transplant, adherence, and responsibility for the functioning of the new organ. The main and moderating effects were tested with regression analyses. Appraisal of transplant-related stressors and emotion-oriented coping were related to all adjustment dimensions, except of adherence and responsibility. Task-oriented coping was positively related to responsibility. Avoidance-oriented coping was negatively correlated with adherence. Only 1 out of 18 hypothesized interactive terms was significant, yielding a synergistic interaction between appraisal of transplant-related stressors and emotion-oriented coping on the sense of guilt. The findings have the potential to inform interventions promoting psychosocial adjustment among KT recipients.

    Background Immunosuppression for immunologically high-risk kidney transplant patients usually involves antithymocyte globulin induction with triple drug maintenance therapy. Alemtuzumab, a humanized anti-CD52 antibody,was expected to be a promising induction therapy agent for kidney transplantation. However, currently no consensus is available about its efficacy and safety. This study aimed to evaluate the efficacy and safety of alemtuzumab as immune induction therapy in highly sensitized kidney transplant recipients.Methods In this prospective, open-label, randomized, controlled trial, we enrolled 23 highly immunological risk patients (panel reactive antibody >20%). They were divided into two groups: alemtuzumab group (trial group) and anti-thymocyte globulin (ATG) group (control group). Patients in the alemtuzumab group received intravenous alemtuzumab (15 mg) as a single dose before reperfusion. At the 24th hour post-operation, another dosage of alemtuzumab (15 mg) was given.The control group received a bolus of rabbit ATG (9 mg/kg), which was given 2 hours before kidney transplantation and lasted until the removal of vascular clamps when the anastomoses were completed. Maintenance immunosuppression in both groups comprised standard triple therapy consisting of tacrolimus, prednisone, and mycophenolate mofetil (MMF).Acute rejection (AR) and infection episodes were recorded, and kidney function was monitored during a 2-year follow-up.χ2 test, t test and Kaplan-Meier analysis were performed with SPSS17.0 software.Results Median follow-up was 338 days. In both the alemtuzumab group and ATG group, creatinine and blood urea nitrogen values in surviving recipients were similar (P >0.05). White blood cell counts were significantly reduced in the alemtuzumab group for the most time points up to 6 months (P <0.05). One patient receiving alemtuzumab died for acute myocardial infarction at the 65th day post-operation. Two ATG patients died for severe pulmonary

    Blood group incompatible transplantation (ABOi) in children is rare as pretransplant conditioning remains challenging and concerns persist about the potential increased risk of rejection. We describe the results of 11 ABOi pediatric renal transplant recipients in the 2 largest centers in the United Kingdom, sharing the same tailored desensitization protocol. Patients with pretransplant titers of 1 or more in 8 received rituximab 1 month before transplant; tacrolimus and mycophenolate mofetil were started 1 week before surgery. Antibody removal was performed to reduce titers to 1 or less in 8 on the day of the operation. No routine postoperative antibody removal was performed. Death-censored graft survival at last follow-up was 100% in the ABOi and 98% in 50 compatible pediatric transplants. One patient developed grade 2A rejection successfully treated with antithymocyte globulin. Another patient had a titer rise of 2 dilutions treated with 1 immunoadsorption session. There was no histological evidence of rejection in the other 9 patients. One patient developed cytomegalovirus and BK and 2 others EBV and BK viremia. Tailored desensitization in pediatric blood group incompatible kidney transplantation results in excellent outcomes with graft survival and rejection rates comparable with compatible transplants.

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

    An ideal anesthetic regimen for kidney transplantation should be able to assure haemodynamic stability to obtain an optimal graft reperfusion. The aim of this study was to compare 2 regimens of anesthesia for patients submitted to kidney transplantation. We studied 40 patients: 20 subjects (Group A) received balanced anesthesia with thiopental, fentanyl and isoflurane, to the others 20 (Group B), a total intravenous anesthesia (TIVA) with propofol and remifentanyl was given. In both groups muscle relaxation was obtained with a bolus of cisatracurium followed by a continuous infusion. We performed standard clinical, invasive blood pressure and central venous pressure monitoring. Hemodyna-mic data have been collected at standard times. During the postoperative period we evaluated the recovery (Aldrete Score) in the recovery room and the analgesia (VAS) at 1, 6, 24 h after the end of surgery. The trend of hemodynamic parameters did not show statistically significant differences between the 2 groups. We observed statistically significant differences concerning the quality of the recovery and the postoperative analgesia. The recovery in group B was faster than in group A, but in group A the pain control was better than in group B at least during the first postoperative hour. For their pharmacokinetic properties, propofol, remifentanyl and cisatracurium allow to obtain a good control of the hemodynamic parameters and a fast and safe recovery of consciousness. Total intravenous anesthesia regimen seems to be an alternative to the balanced anesthesia for patients undergoing kidney transplantation.

    Kidney transplant is a last resort to increase the life expectancy and quality of life in patients with renal failure. Aortic dissection is a disease that requires emergency intervention; it is characterized by sudden life-threatening back or abdominal pain. In the case described, constant chest pain that increased with respiration was present on examination of a 28-year-old man (85 kg, 173 cm) who presented at our emergency department complaining of severe back pain. He had undergone a kidney transplant in 2004 from his mother (live donor). He was diagnosed with acute Type II aortic dissection and was scheduled for emergent surgery. Because there were no surgical or anesthetic complications, the patient with 79 and 89 minutes aortic cross-clamping and cardiopulmonary bypass durations was sent, intubated, to intensive care unit. When nephrotoxic agents are avoided and blood flow is stabilized, cardiovascular surgery with cardio-pulmonary bypass may be performed seamlessly in patients who have undergone a kidney transplant.

    Despite prolonged survival and better quality of life as compared to dialysis, kidney transplantation frequently presents with a complex set of medical issues that require intensive management to protect graft function. Metabolic acidosis has an impact on several metabolic complications such as mineral and muscle metabolism, nutritional status and anemia. It may also have an effect on graft function, possibly through the stimulation of adaptive mechanisms aimed at maintaining acid-base homeostasis. We investigated current practice in the evaluation of metabolic acidosis at one of the largest transplant centers in the Eurotransplant region. Adult renal transplant recipients having received allograft from January 2011 to August 2012 were included in the investigation. We recorded the frequency of measuring the parameters of venous blood gas analysis, as well as creatinine and urea levels, creatinine clearance, proteinuria, calcium, phosphate and potassium blood levels, body mass index and the time spent on dialysis prior to kidney transplantation. Out of 203 patients who had received renal allograft at our institution during the observed period, 191 (124 males and 67 females, age range from 18 to 77 years) were enrolled in the study. Of these, only 92 (48.167%) patients had parameters of venous blood gas analysis measured at some time after kidney transplantation. Acid-base status was determined more often in males (77 males vs. 22 females, p = 0.001). Patients with pH/blood gas analysis performed were found to have significantly higher creatinine and urea levels and significantly lower creatinine clearance (p Metabolic acidosis is a very important clinical issue that needs to be monitored in every transplant recipient. Its effects on graft function, nutritional status, anemia and bone mass are complex but can be successfully managed. Our study showed metabolic acidosis to be linked with significantly higher creatinine and urea levels, decreased creatinine clearance

    Long lasting debates in the past questioned the relevance of any sort of compatibility in post mortal kidney transplantation. It is for no say that fully compatible transplants have the highest chances for a long patient and graft survival. In the present report the use of HLA-DR as a representative of the Major Histocompatibility Complex class II genes in the allocation of organs is discussed. The major arguments are the easiness to offer to patients a compatible graft in a relatively short waiting time, an increase in graft survival, the less sensitization during the transplantation period, and the lower waiting time for a retransplant. Even if the number of organ donors remains the same a lowering of the mean waiting time is expected because of the longer period of graft survival.

  12. Vitamin D: a new player in kidney transplantation?

    Science.gov (United States)

    Ponticelli, Claudio; Sala, Gabriele

    2014-10-01

    Vitamin D is a hormone with pleiotropic effects. It mainly regulates calcium and phosphate metabolism through interactions with FGF23 and its receptor klotho. In addition, it has been shown that Vitamin D also regulates the immune response and has protective effects from cardiovascular disease, cancer and infections. Most renal transplant recipients have overt Vitamin D deficiency, a condition that may be associated with a decline in graft function and other complications. After kidney transplantation, elevated levels of FGF23 may predict increased risks of death and allograft loss. Theoretically, an optimal Vitamin D supplementation might favor operational tolerance and protect transplant recipients from the triad cardiovascular disease-cancer-infection. However, more solid data are needed to confirm this and to set the optimal level of serum Vitamin D supplementation in order to attain the best clinical outcome.

  13. Pregnancy after kidney transplantation: high rates of maternal complications

    Directory of Open Access Journals (Sweden)

    Cristina Candido

    Full Text Available Abstract Introduction: Women regain fertility a few time after renal transplantation. However, viability of pregnancy and maternal complications are still unclear. Objective: To describe the outcomes of pregnancies in kidney transplanted patients, focusing on maternal complications. Methods: Retrospective study of pregnancies in kidney transplanted patients between 2004 and 2014, followed up 12 months after delivery. Each pregnancy was considered an event. Results: There were 53 pregnancies in 36 patients. Mean age was 28 ± 5years. Pregnancy occurred 4.4 ± 3.0 years post-transplant. Immunosuppression before conception was tacrolimus, azathioprine, and prednisone in 74% of the cases. There were 15% miscarriages in the 1st trimester and 8% in 2nd trimester. In 41% of the cases, it was necessary to induce labor. From all births, 22% were premature and 17% very premature. There were 5% stillbirths and 5% of neonatal deaths. De novo proteinuria occurred in 60%, urinary tract infection in 23%, preeclampsia in 11%, acute rejection in 6%, and graft loss in 2% of the cases. It was observed a significant increase in creatinine at preconception comparing to 3rd trimester and follow-up (1.17 vs. 1.46 vs. 1.59 mg/dL, p < 0.001. Conclusion: Although the sample is limited, the number of miscarriages was higher than in the general population, with high rates of maternal complications. Sustained increase of creatinine suggests increased risk of graft loss in long-term.

    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.

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

    Embryonic kidney xenotransplantation could represent a new solution to the scarcity of kidneys for transplantation. To determine the feasibility of allogeneic laparoscopic transplantation of metanephroi (M) in rabbits. Microscopic dissection was conducted to obtain metanephroi from 14-day-old (24M), 15-day-old (20M) and 16-day-old (26M) embryos. Using single-port abdominal laparoscopy, a spinal needle was inserted percutaneously, through which the metanephroi were deposited (using an epidural catheter) close to a patent blood vessel in the retroperitoneal fat. Seventy metanephroi were transplanted to 18 rabbits. Three weeks later, the animals were examined through open surgery. We compared the embryonic maturity, the morphometric variables of the metanephroi and the development rate of the transplanted metanephroi. The lower time limit for the extraction of metanephroi from the rabbits was day 14. Three weeks after transplantation, only 3/24 14-day-old metanephroi grew at minimal expression (12.5%). In contrast, 10/20 (50%) 15-day-old and 12/26 (46.1%) 16-day-old metanephroi grew. These metanephroi had differentiated sufficiently for the glomeruli, proximal and distal tubules and collecting ducts to develop normally. We detected no relevant immunological changes in the peripheral blood. We have described for the first time in the literature the allogeneic laparoscopic transplantation of metanephroi from embryos as a feasible and noninvasive technique. The recipients did not require immunosuppression. Copyright © 2015 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    Color-encoded duplex ultrasonography (CEDU) makes a more accurate technique in kidney graft monitoring by combining real-time US with pulsed Doppler studies of renal vasculature. It is a non-invasive and easy technique. Suitable to study the whole renal artery and vein, CEDU also allows the qualitative and quantitative assessment of the intrarenal vasculature and therefore the easy diagnosis of such vessel dysfunctions as arteriovenous fistulas following biopsy. Moreover, Doppler spectral analysis can be used to distinguish among different causes of renal allograft dysfunction--i.e. rejection, cyclosporine nephrotoxicity or acute tubular necrosis. The value of the resistive index for the differential diagnosis is discussed. CEDU allows a more reliable measurement of renal blood flow thanks to the more precise evaluation of renal artery diameter and mean flow velocity.

    Cryptococcosis is a severe fungal infection with a high mortality rate among solid-organ transplant recipients. Today, China is among the countries performing the most kidney transplants worldwide, however data on the association of cryptococcosis with kidney transplantation in mainland China remain scarce and fragmented. We retrospectively analyzed cases of culture-confirmed cryptococcosis following kidney transplantation that have occurred at our hospital and reviewed the published cases in China over the last 30 years. Cryptococcosis in kidney transplant recipients was mainly caused by Cryptococcus neoformans var. grubii VNI strains and occurred most frequently in patients aged 41-50 years (37.9%, 11/29). The average time to infection after kidney transplantation was 5.16 ± 3.97 years. The clinical manifestations were found to be diverse, with slight to moderate headache and fever, meningeal irritation, and high cerebrospinal fluid pressure being relatively common. Physicians should be alert to these symptoms among kidney transplant recipients. Cryptococcosis is a serious infection among kidney transplant recipients in mainland China. It has unique characteristics, such as a relatively long time to onset after kidney transplantation, and diverse clinical manifestations. Treatment with intrathecal injection of amphotericin B is considered effective for central nervous system involvement. The findings of this study also highlight the urgent need for multicenter, prospective, and multidisciplinary clinical studies and education on cryptococcosis in kidney transplant recipients in China.

    Exercise intolerance is an important comorbidity in patients with CKD. Anaerobic threshold (AT) determines the upper limits of aerobic exercise and is a measure of cardiovascular reserve. This study investigated the prognostic capacity of AT on survival in patients with advanced CKD and the effect of kidney transplantation on survival in those with reduced cardiovascular reserve. Using cardiopulmonary exercise testing, cardiovascular reserve was evaluated in 240 patients who were waitlisted for kidney transplantation between 2008 and 2010, and patients were followed for ≤5 years. Survival time was the primary endpoint. Cumulative survival for the entire cohort was 72.6% (24 deaths), with cardiovascular events being the most common cause of death (54.2%). According to Kaplan-Meier estimates, patients with AT ratio, 4.48; 95% confidence interval, 1.78 to 11.38; P=0.002). Survival did not differ significantly among patients with AT ≥40%, with one death in the nontransplanted group and no deaths in the transplanted group. In summary, this is the first prospective study to demonstrate a significant association of AT, as the objective index of cardiovascular reserve, with survival in patients with advanced CKD. High-risk patients with reduced cardiovascular reserve had a better survival rate after receiving a kidney transplant.

    Racial and ethnic disparities among North American patients with chronic kidney disease have received significant attention. In contrast, little is known about health-related outcomes of patients with end-stage renal disease among the Roma minority, also known as gypsies, compared to Caucasian individuals. We prospectively assessed the association between Roma ethnicity and long-term clinical outcomes in kidney transplant recipients. In a prevalent cohort of renal transplant recipients, followed up over a median of 94 months, we prospectively collected socio-demographic, medical (and transplant related) characteristics and laboratory data at baseline from 60 Roma and 1,003 Caucasian patients (mean age 45 (SD = 11) and 49 (SD = 13) years, 33 and 41% women, 18 and 17% with diabetes mellitus, respectively). Survival analyses examined the associations between Roma ethnicity and all-cause mortality and death-censored graft loss or death with functioning renal allograft. During the follow-up period, 341 patients (32%) died. Two-hundred eighty (26%) patients died with a functioning graft and 201 patients (19%) returned to dialysis. After multivariable adjustments, Roma ethnicity was associated with 77% higher risk of all-cause mortality (Hazard Ratio (HR): 1.77; 95% confidence interval (CI): 1.02, 3.07), two times higher risk of mortality with functioning graft (2.04 [1.17-3.55]) and 77% higher risk of graft loss (1.77 [1.01-3.13]), respectively. Roma ethnicity is independently associated with increased mortality risk and worse graft outcome in kidney transplant recipients. Further studies should identify the factors contributing to worse outcomes among Roma patients.

    Length of hospital stay post-renal transplant was investigated in 2171 North American pediatric patients. Hospitalization for those surviving one year with a functioning graft was 28.8 versus 36.0 days (P < 0.05) for living donor (LD) compared with cadaveric donor (CAD) recipients during the first year post-transplant. Significantly prolonged hospital stays were recorded for LD recipients who (a) were less than one-year-old, (b) were receiving prophylactic ALG/OKT3, and (c) had a history of prior dialysis, and for CAD recipients who (a) were non-White and (b) received kidneys with cold ischemic times over 24 hours. In period II (2 to 6 months post-transplant), 51% and 68% of LD and CAD recipients, respectively were hospitalized while the corresponding values were 27% or 31% in period III (7 to 12 months post-transplant). Hospitalization was due mainly to graft loss or rejection episodes. Prolonged hospital stay coupled with poor graft survival might help to determine which aspects of the clinical practice of transplanting children warrant changes.

    The continuing demand for transplantable organs leads to ongoing debates about organ procurement, even with arguments in favour of xenotransplantation as a valid alternative. This article examines the management of kidneys with major anatomical anomalies, almost one-quarter of those available for transplantation in our experience: the decision-making is considered from a scientific and an ethical standpoint. Surgical techniques include primary revascularization (PR) and/or bench-top reconstructions (BR). The results, examined for 1311 normal grafts (Group I) and 362 grafts presenting major anatomical anomalies (Group II), all transplanted for the first time, showed almost the same rates of failures due to surgical causes in these two groups. No operative mortality was associated with any of the vascular techniques, BR being easier and safer than PR. Graft survival at 1 year is the same for Group I and Group II (85% versus 84%, respectively). An ethical allocation system ought to take into account the experience of the transplant surgeon for maximizing outcome and minimizing cost and risk for transplantation.

    The 5-year and 10-year graft survivals for 186 deceased donor (DD) transplants performed at National University Health System (NUHS) were 79.9% and 58.4% respectively. 5-year and 10-year patient survivals for DD transplants performed at NUHS were 94.2% and 83.4%. The 5-year and 10-year graft survivals for 128 living donor (LD) transplants performed at NUHS were 90.2% and 72% respectively. 5-year and 10-year patient survivals for DD transplants performed at NUHS were 98.6% and 95.1%. The projected graft half lives were 14.6 and 20.6 years for DD and LD transplants respectively. These results compare favorably with the 10-year survival rates of 40% and 58% for DD and LD grafts reported by the United States Renal Data System (USRDS) in 2010. The younger age and the lower prevalence of diabetes and HLAmismatch in the DD and LD transplant study populations, in comparison to the USRDS population and perhaps better access and compliance to maintenance immunosuppression, could have contributed to these excellent outcomes. The 5-year and 10-year graft survivals for 162 transplants receiving what were likely deceased donor kidneys from China were 89.2% and 69.2% respectively. Although these survivals were apparently better than that for DD performed at NUHS, the advantage for China Tx disappeared when DD with primary non function or vascular thrombosis were excluded from analysis. The 5-year and 10-year patient survivals for 30 transplants receiving live non-related transplants from India were 82.3% and 60.1%. Both groups were considered to have received commercial transplants based on various aspects of history from the patients. Among those receiving China_Tx or India Tx, there were a disproportionate number of males and Chinese; and a significant proportion underwent pre-emptive transplant or transplant after only a short period of dialysis. Prevalence of post-transplant hepatitis B was significantly higher among China_Tx than their DD counterparts (7.7% vs. 1.2%, P = 0

    Kidney transplantation is the preferred clinical and most cost-effective option for end-stage renal disease. Significant advances have taken place in the care of the transplant patients with improvements in clinical outcomes. The optimization of the costs of transplantation has been a constant goal as well. We present herein the impact in financial outcomes of a shortened length of stay after kidney transplant. PMID:24436592

    The purpose of this longitudinal observational study was to (i) examine the change of daily physical activity in 28 adult kidney transplant recipients over the first 12 months following transplantation; and (ii) to examine the change in metabolic characteristics and renal function. Accelerometer-based daily physical activity and metabolic- and clinical characteristics were measured at six wk (T1), three months (T2), six months (T3) and 12 months (T4) following transplantation. Linear mixed effect analyses showed an increase in steps/d (T1 = 6326 ± 2906; T4 = 7562 ± 3785; F = 3.52; p = 0.02), but one yr after transplantation only 25% achieved the recommended 10 000 steps/d. There was no significant increase in minutes per day spent on moderate-to-vigorous intensity physical activity (T1 = 80.4 ± 63.6; T4 = 93.2 ± 55.1; F = 1.71; p = 0.17). Body mass index increased over time (T1 = 25.4 ± 3.2; T4 = 27.2 ± 3.8; F = 12.62; p physical activity, the majority did not meet the recommended levels of physical activity after one yr. In addition to the weight gain, this may result in negative health consequences. Therefore, it is important to develop strategies to support kidney transplant recipients to comply with healthy lifestyle recommendations, including regular physical activity.

    Full Text Available Tacrolimus dosing to establish therapeutic levels in recipients of organ transplants is a challenging task because of much interpatient and intrapatient variability in drug absorption, metabolism, and disposition. In view of the reported impact of gut microbial species on drug metabolism, we investigated the relationship between the gut microbiota and tacrolimus dosing requirements in this pilot study of adult kidney transplant recipients. Serial fecal specimens were collected during the first month of transplantation from 19 kidney transplant recipients who either required a 50% increase from initial tacrolimus dosing during the first month of transplantation (Dose Escalation Group, n=5 or did not require such an increase (Dose Stable Group, n=14. We characterized bacterial composition in the fecal specimens by deep sequencing of the PCR amplified 16S rRNA V4-V5 region and we investigated the hypothesis that gut microbial composition is associated with tacrolimus dosing requirements. Initial tacrolimus dosing was similar in the Dose Escalation Group and in the Stable Group (4.2 ± 1.1 mg/day vs. 3.8 ± 0.8 mg/day, respectively, P=0.61, two-way between-group ANOVA using contrasts but became higher in the Dose Escalation Group than in the Dose Stable Group by the end of the first transplantation month (9.6 ± 2.4 mg/day vs. 3.3 ± 1.5 mg/day, respectively, P<0.001. Our systematic characterization of the gut microbial composition identified that fecal Faecalibacterium prausnitzii abundance in the first week of transplantation was 11.8% in the Dose Escalation Group and 0.8% in the Dose Stable Group (P=0.002, Wilcoxon Rank Sum test, P<0.05 after Benjamini-Hochberg correction for multiple hypotheses. Fecal Faecalibacterium prausnitzii abundance in the first week of transplantation was positively correlated with future tacrolimus dosing at 1 month (R=0.57, P=0.01 and had a coefficient ± standard error of 1.0 ± 0.6 (P=0.08 after multivariable linear

The objective of this study was to examine the representations of the transplanted organ and their relationship with emotional and mood factors, illness perceptions, and the functioning of the transplanted organ. One hundred and sixty-four kidney transplant patients were assessed using the Spielberger Anxiety Inventory, the Beck’s Depression Scale, the Posttraumatic Growth Inventory, the Brief Illness Perception Questionnaire, and the Transplanted Organ Questionnaire. Medical parameters were collected from the routine clinical blood tests (serum creatinine and estimated glomerular filtration rate levels and biopsy results. Our most outstanding results suggest that kidney-transplanted patients’ illness representations are associated with health outcomes. The Transplanted Organ Questionnaire “psychological rejection” subscale was connected with higher serum creatinine and estimated glomerular filtration rate levels. Logistic regression analysis showed that psychological rejection subscale, Brief Illness Perception Questionnaire, and Posttraumatic Growth Questionnaire total scores were associated with graft rejection. These results may serve as a basis for the development of complex treatment interventions, which could help patients to cope with the bio-psycho-social challenges of integrating the new organ as part of their body and self.

    Limited qualitative research has explored opinions of kidney disease health care providers regarding racial and ethnic disparities in access to and receipt of kidney transplantation. Key informant interviews were conducted among transplant nephrologists, nephrologists, transplant social workers, and transplant coordinators to determine barriers to transplantation among African Americans compared to whites with end-stage renal disease (ESRD). Thirty-eight interviews were audio recorded and transcribed to hardcopy for content analysis. Grounded theory was used to determine dominant themes within the interviews. Reliability and validity were ensured by several coinvestigators independently sorting verbatim responses used for generating themes and subsequent explanations. Several major categories arose from analysis of the transcripts. Under the category of personal and social responsibility for kidney transplantation, interviews revealed 4 major themes: negative personal behaviors, acquisition of and lack of self-treatment of comorbid conditions, lack of individual responsibility, and the need for more social responsibility. Many providers perceived patients as being largely responsible for the development of ESRD, while some providers expressed the idea that more social responsibility was needed to improve poor health status and disparities in kidney transplantation rates. Kidney disease health providers seemed torn between notions of patients' accountability and social responsibility for racial disparities in chronic kidney disease and ESRD. Further research is needed to clarify which aspects contribute most to disparities in access to transplantation.

    A new proposal has been created for establishing medical criteria for organ allocation in recipients receiving simultaneous liver-kidney transplants. In this article, we describe the new policy, elaborate on the points of greatest controversy, and offer a perspective on the policy going forward. Although we applaud the fact that simultaneous liver-kidney transplant activity will now be monitored and appreciate the creation of medical criteria for allocation in simultaneous liver-kidney transplants, we argue that some of the criteria proposed, especially those for allocating a kidney to a liver recipient with AKI, are too liberal. We call on the nephrology community to follow the consequences of this new policy and push for a re-examination of the longstanding policy of allocating kidneys to multiorgan transplant recipients before all other candidates. The charge to protect our system of equitable organ allocation is very challenging, but it is a challenge that we must embrace.

    Background: Kidney transplantation is associated with various biochemical abnormalities such as changes in serum blood level of sodium (Na), potassium (K), calcium (Ca), and phosphorous (P). Although cyclosporine (CsA) is used commonly, the prevalence of its side effects, including electrolytes disturbance, is not well understood. Objective: To find the prevalence of electrolytes disturbance and its relation to CsA blood levels. Methods: In a retrospective study, 3308 kidney transplant recipients transplanted between 2008 and 2011 were studied. We evaluated the relation between serum Ca, P, Na, K and CsA trough (C0) and 2-hour post-dose (C2) levels. Results: The mean±SD age of recipients was 37±15 years; 63% of patients were male. Overall, C2 levels had correlation with Ca blood level (p=0.018; OR: 1.13, 95%CI: 1.02–1.25), C0 levels had also correlation with blood levels of P and Cr (p<0.001; OR: 1.83, 95% CI: 1.59–2.11). Conclusion: Electrolyte disturbances are prevalent. Higher serum levels of CsA can worsen the allograft function by disturbing the serum P and Ca levels. PMID:25013642

    In general, cadaver kidney transplantation survival remains at 40-50% for the first year after transplantation. To compare the beneficial effect of a new immunosuppressive protocol to standard therapy (azathioprine and prednisone), we have studied 30 high risk first cadaveric renal allograft recipients who were randomly selected before (Group A, n.15) and after (Group B, n.15) 10/79. At 12 mos, actuarial graft survival of Group B is 75% compared to 46% in Group A. Actuarial patient survival for Group B is 94% for one year compared to 60% in Group A. We feel that these improved results are related to basic changes in our immunosuppressive protocol. These changes consist of: 1. Low doses of azathioprine and prednisolone (less than 1 mg/kg) with rapid reduction to very low levels (less than 0.3 mg/kg); 2. ALG administration at 30 mg/kg/day for 14 times; 3. Rapid placement (one month) on alternate day steroid therapy; 4. Elimination of steroids for the treatment of rejection; 5. Use of ALG (20 mg/kg/day for 10 days) for the treatment of rejection; 6. Use of ALG combined with modified lymph node irradiation for third rejection episodes; and 7. Long-term intermittent ALG administration provided that kidney function continues to be normal. The best immunosuppressive protocol is clearly the one associated with less morbidity and improved quality of life after transplantation. Our current protocol (Group B) provides the best results.

    Heart and kidney allografts showed markedly prolonged survival in unrelated mongrel dogs following total lymphoid irradiation (TLI) and donor bone marrow without any other immunosuppression. In every animal the heart survived longer than the kidney. Placing the kidney allograft in the abdomen with the bone marrow given intraperitoneally doubled kidney survival over placement in the neck, but heart survival was equally prolonged in the abdomen or neck. Splenectomy before TLI or after TLI, but just before transplantation, almost completely eliminated the prolonged survival of both heart and kidney allografts. Thus there is suggestive evidence that TLI plus bone marrow from the donor may be valuable for transplantation in man, particularly heart transplantation.

    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.

    We present a case of tacrolimus-induced encephalopathy after successful kidney transplantation. An 11-year-old girl presented with sudden onset of neurologic symptoms, hypertension, and psychiatric symptoms, with normal kidney function, after kidney transplantation. The symptoms improved after cessation of tacrolimus. Magnetic resonance imaging (MRI) showed acute infarction of the middle cerebral artery (MCA) territory in the right frontal lobe. Three days later, she had normal mental function and maintained normal blood pressure with left hemiparesis. Follow-up MRI was performed on D19, showing new infarct lesions at both cerebral hemispheres. Ten days later, MRI showed further improvement, but brain single photon emission computed tomography (SPECT) showed mild reduction of uptake in both the anterior cingulate gyrus and the left thalamus. One month after onset of symptoms, angiography showed complete resolution of stenosis. However, presenting as a mild fine motor disability of both hands and mild dysarthria, what had been atrophy at both centrum semiovale at 4 months now showed progression to encephalomalacia. There are two points of interest in this case. First, encephalopathy occurred after administration of tacrolimus and improved after discontinuation of the drug. Second, the development of right-side hemiplegia could not be explained by conventional MRI; but through diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) of white matter tract, visualization was possible.

    Background: the aim of this work is to demonstrate that the value of the mean transit time (MTT) obtained from the {sup 99m}Tc-MAG3 renogram deconvolution is related to the levels of adenine nucleotides determined in cortical biopsies from transplanted kidneys. Methods: the functional state was estimated by means of the MTT and the initial height (HO) of the renal retention function obtained from the {sup 99m}Tc-MAG3 renogram deconvolution and by the measure of adenine nucleotides obtained from biopsies. We studied 30 kidney graft recipients, 25 normal functioning grafts (NFG) and 5 with acute tubular necrosis (ATN). Results: the MTT is significantly longer for ATN (p<0.001). The initial uptake values (HO) are significantly lower for ATN (p<0.001). The sum of adenine nucleotides (SAN) is significantly greater for NFG than for ATN (p<0.001). The values of the MTT seem to reflect the energy state of the cells in transplanted kidney. Conclusion: the analysis of MTT may be indicative of the functional metabolic recovery and thus it may be predictive of the renal graft function at least in the same extent than the biochemical analysis of a cortical renal biopsy immediately after blood reperfusion of the tissue.

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

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

    With the advances in technical skills,management of postoperative complications and improvements in immunosuppressive drugs,liver transplantation is the standard treatment for many patients with chronic liver disease.Today,shortage of donor organs seems to be the major limiting factor for the application of liver transplantation.This review focuses on five issues that are challenging to clinical practice of liver transplantation and relevant to gastroenterologists.These include living donor liver transplantation,recurrent viral hepatitis,non-heart-beating donors,hepatocellular carcinoma,and ABO incompatible livertransplantation.Living donor and non-heart beating donor transplantations were initiated as a solution to increase the donor organ pool and it is expected that there will be an increase in the number of these donors.Recurrent hepatitis C and hepatocellular carcinoma following liver transplantation are among major problems and ongoing research in these diseases may lead to better outcomes in these recipients.

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

    Full Text Available Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396, comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04. Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex.

    BK polyomavirus (BKPyV) reactivation in kidney transplant recipients can lead to allograft damage and loss. The elements of the adaptive immune system that are permissive of reactivation and responsible for viral control remain incompletely described. We performed a prospective study evaluating BKPyV-specific T-cell response, humoral response and overall T-cell phenotype beginning pre-transplant through one year post-transplant in 28 patients at two centers. We performed an exploratory analysis of risk factors for the development of viremia and viruria as well as compared the immune response to BKPyV in these groups and those who remained BK negative. 6 patients developed viruria and 3 developed viremia. BKPyV-specific CD8+ T-cells increased post-transplant in viremic and viruric but not BK negative patients. BKPyV-specific CD4+ T-cells increased in viremic, but not viruric or BK negative patients. Anti-BKPyV IgG antibodies increased in viruric and viremic patients but remained unchanged in BK negative patients. Viremic patients had a greater proportion of CD8+ effector cells pre-transplant and at 12 months post-transplant. Viremic patients had fewer CD4+ effector memory cells at 3 months post-transplant. Exploratory analysis demonstrated lower CD4 and higher total CD8 proportions, higher anti-BKPyV antibody titers and the cause of renal failure were associated BKPyV reactivation. In conclusion, low CD4, high CD8 and increased effector CD8 cells were found pre-transplant in patients who became viremic, a phenotype associated with immune senescence. This pre-transplant T-cell senescence phenotype could potentially be used to identify patients at increased risk of BKPyV reactivation.

    Full Text Available Objective To analyze the clinical characteristics, risk factors, treatment and turnover of the polycythemia after kidney transplantation. Methods The clinical data of 329 renal transplantation recipients who had undergone kidney transplantation in the Transplant Center of 309 Hospital of PLA from Jan. 2008 to Jan. 2012, were retrospectively analyzed. Posttransplant erythrocytosis (PTE was found in 65 recipients (PTE group, and no PTE was found in 264 recipients (control group. The pre- and post-operative parameters, the therapeutic effect of different treatments, and outcomes were compared between PTE group and control group. Results Patients in PTE group were younger, and the ratio of males was higher compared with that of control group (P0.05. PTE incidence was higher in recipients (24.3%, n=185 who had accepted cyclosporine than those recipients (13.9%, n=144 who had accepted tacrolimus, and the difference was statistically significant (P0.05, but the relapse rate and the embolism rate due to concurrent thrombus were lower in conservative treatment group than in venesection group with statistical significance (P<0.05. Conclusion PTE is more common in male recipients with good graft function. Smoking, high nutritional status, concomitant hypertension and diabetes are the risk factors for PTE. Administration of tacrolimus may reduce the PTE incidence. Compared with venesection treatment, conservative treatment may be more effective in treating PTE with lower relapse rate and embolism rate due to concurrent thrombus.

    An increased number of sensitized patients await kidney transplantation (KTx). Sensitization has a major impact on patient mortality and morbidity due to prolonged waiting time and may preclude live donor transplantation. However, recent reports have shown that KTx can be performed successfully using novel immunosuppressive protocols. This study presents our experience with patients displaying donor-specific antibody (DSA) (+). We enrolled 5 lymphocyte cross-match (LCM) negative (complement-dependent cytotoxicity) and panel-reactive antibody (PRA) plus DSA-positive patients mean fluorescein intensity [MFI] > 1000) who underwent living kidney donor procedures. All subjects were females and their mean age was 36.7 years. In our protocol, we started mycophenolate mofetil (2 g/d), tacrolimus (0.01 mg/kg) and prednisolone (0.5 mg/kg) on day -6. We performed 2 sessions of total plasma exchange (TPE) with albumin replacement and administered 2 doses of IVIG (5 g/d). On day -1, we added rituximab (200 mg). On the operation day and on day +4, the patients received doses of basiliximab. Serum samples were taken on days -6, 0, and 30 as well as at 1 year after transplantation. All patients displayed immediate graft function. Mean basal DSA titer was 5624 MFI. After desensitization, the MFI titers decreased at the time of transplantation to 2753 MFI, and were 2564 MFI at the 1st month and 802 MFI at 1st year. Three patients experienced acute rejection episodes (60%). After treatment for rejection, the average follow-up was 17 months and last creatinine levels were 0.6-0.8 mg/dL (minimum-maximum). In conclusion, KTx can be succesfully performed in sensitized patients displaying DSA. However, there seems to be a greater acute rejection risk. There is no consensus regarding adequate doses of IVIG or plasmapheresis treatments; furthermore, more studies are needed to clarify the safe MFI titer of the DSA.

    Antibody-mediated rejection (ABMR) is implicated in 45% of renal allograft failure and 57% of late allograft dysfunction. Peritubular capillary C4d is a specific but insensitive marker of ABMR. The 2013 Banff Conference ABMR revised criteria included C4d-negative ABMR with evidence of endothelial-antibody interaction. We hypothesized that endothelial activation and lymphangiogenesis are increased with C4d-negative ABMR and correlate with intragraft T-regulatory cells and T-helper 17. Seventy-four renal transplant biopsies were selected to include (a) ABMR with C4d Banff scores ≥2 (n = 35), (b) variable microvascular injury and C4d score 0-1 (n = 24), and (c) variable microvascular injury and C4d score = 0 (n = 15). Controls included normal preimplantation donor kidneys (n = 5). Immunohistochemistry for endothelial activation (P- and E-selectins [SEL]), lymphangiogenesis (D2-40), T-regulatory cells (FOXP3), and T-helper 17 (STAT3) was performed. Microvessel and inflammatory infiltrate density was assessed morphometrically in interstitium and peritubular capillaries. All transplants had significantly higher microvessel and lymph vessel density compared with normal. Increased expression of markers of endothelial activation predicted transplant glomerulopathy (P-SEL, P = .003). Increased P-SEL and D2-40 were associated with longer interval from transplant to biopsy (P = .005). All 3 markers were associated with increased interstitial fibrosis, tubular atrophy, and graft failure (P-SEL, P < .001; E-SEL, P = .0011; D2-40, P = .012). There was no association with the intragraft FOXP3/STAT3 ratio. We conclude that endothelial activation and lymphangiogenesis could represent a late response to injury leading to fibrosis and progression of kidney damage, and are independent of the intragraft FOXP3/STAT3 ratio. Our findings support the therapeutic potential of specifically targeting endothelial activation.

    Rhodococcus equi is a well-recognized pathogen in veterinary medicine that can also affect immuno-compromised human subjects. The most common clinical features in humans include necrotizing pneumonia with subacute pulmonary disease, progressive cough, chest pain and fever. We report a case of a 49-year-old kidney transplant patient who developed a Rhodococcus equi infection characterized by multiple abscesses of the soft tissues and muscles without any respiratory manifestation. Combining specific antibiotic therapy and surgical management of the abscesses without immunosuppression discontinuation led to a complete recovery of both patient and graft.

    Kidney transplantation has emerged as the treatment of choice for many patients with end-stage renal disease, which is a significant cause of morbidity and mortality. Given the shortage of clinically available donor kidneys and the significant incidence of allograft dysfunction, a noninvasive and accurate assessment of the allograft renal function is critical for postoperative management. Prompt diagnosis of graft dysfunction facilitates clinical intervention of kidneys with salvageable function. New advances in magnetic resonance imaging (MRI) technology have enabled the calculation of various renal parameters that were previously not feasible to measure noninvasively. Diffusion-weighted imaging provides information on renal diffusion and perfusion simultaneously, with quantification by the apparent diffusion coefficient, the decrease of which reflects renal function impairment. Diffusion-tensor imaging accounts for the directionality of molecular motion and measures fractional anisotropy of the kidneys. Blood oxygen level-dependent MR evaluates intrarenal oxygen bioavailability, generating the parameter of R2* (reflecting the concentration of deoxyhemoglobin). A decrease in R2* could happen during acute rejection. MR nephro-urography/renography demonstrates structural data depicting urinary tract obstructions and functional data regarding the glomerular filtration and blood flow. MR angiography details the transplant vasculature and is particularly suitable for detecting vascular complications, with good correlation with digital subtraction angiography. Other functional MRI technologies, such as arterial spin labeling and MR spectroscopy, are showing additional promise. This review highlights MRI as a comprehensive modality to diagnose a variety of etiologies of graft dysfunction, including prerenal (e.g., renal vasculature), renal (intrinsic causes) and postrenal (e.g., obstruction of the collecting system) etiologies.

    Little is known about the actual kidney graft temperature during the 2nd warm ischemia time (WIT2). We aimed to determine the actual temperature course of the WIT2, with emphasis on the 15 °C metabolic threshold. Data of 152 consecutive adult living donor kidney transplantations were collected. The mean WIT2 was 41.3 ± 10.1 (SD) minutes with a temperature of 5.4 °C at baseline which gradually increased to 13.7, 17.4, and 20.2 °C after 10, 20, and 30 min, respectively. The percentage of kidneys with a temperature of 15 °C or higher was 81.2% after 20 min and 97.5% after 30 min. Duration of surgery (95% CI: -0.017 to -0.002, P = 0.02), multiple veins (95% CI: 0.0003-2.720, P = 0.05) and WIT2 (95% CI: 0.016-0.099, P = 0.006) were associated with a rapid temperature increase. No correlation could be determined between a rapid temperature rise and diminished graft function. This study showed a rapid increase in kidney temperature during WIT2, wherein the 15 °C threshold was reached within 20 min in more than 80% of the patients.

    The severe organ shortage in Israel has prompted many patients to undergo kidney transplantation abroad. In May 2008, the Israeli Knesset approved the Israel Transplant Law prohibiting organ trade and disallowing health insurers to reimburse the cost of illegal transplantation abroad. The aim of this study was to assess the initial effect of the law on kidney transplantations inside and outside the country. The number of kidney transplantations performed inside and outside Israel was compared between the 3-year periods before and after implementation of the transplant law (2006-2008 and 2009-2011). Further analysis compared the number of deceased-donor and live-donor transplantations performed in Israel during the same periods. The results showed that the number of transplants performed abroad dropped significantly, from a median of 143 per year during 2006-2008 to Israel Transplant Law has dramatically affected kidney transplantation practices in Israel by reducing transplantation tourism and increasing living-donor kidney transplantations.

    Kidney transplant outcomes are influenced by donor characteristics, including age and gender. Additional donor factors, both genetic and environmental, also influence graft outcome. We aim to assess the strength of donor factors in determining kidney transplant outcomes by comparing paired kidneys from a single donor transplanted into different recipients. We conducted a retrospective cohort study of outcomes of pairs of deceased donor kidneys transplanted in our centre between 1992 and 2008. We examined the relationship within pairs for eGFR at 1 year and at 5 years post-transplant using Spearman\\'s Correlation and the concordance of pairs of transplant kidneys with respect to the occurrence of acute rejection and delayed graft function (DGF). A total of 652 recipient pairs were analysed. Spearman\\'s correlation for eGFR was 0.36 at 1 year and 0.36 at 5 years post-transplant. The incidence of DGF was 11%. The odds ratio of DGF occurring if the contralateral kidney had DGF was 5.99 (95% CI, 3.19-11.25). There is a significant degree of relationship within pairs of kidneys transplanted from the same donor for serum creatinine at 1 year and 5 years post-transplant and also for the occurrence of delayed graft function.

    Type 1 diabetes recurrence has been documented in simultaneous pancreas-kidney transplants (SPKT), but this diagnosis may be underestimated. Antibody monitoring is the most simple, noninvasive, screening test for pancreas autoimmune activity. However, the impact of the positive autoimmune markers on pancreas graft function remains controversial. In our cohort of 105 SPKT, we studied the cases with positive pancreatic autoantibodies. They were immunosuppressed with antithymocyte globulin, tacrolimus, mycophenolate, and steroids. The persistence or reappearance of these autoantibodies after SPKT and factors associated with their evolution and with graft outcome were analyzed. Pancreatic autoantibodies were prospectively monitored. Serum samples were collected before transplantation and at least once per year thereafter. At the end of the follow-up (maximum 138 months), 43.8% of patients were positive (from pre-transplant or after recurrence) for at least one autoantibody - the positive group. Antiglutamic acid decarboxylase was the most prevalent (31.4%), followed by anti-insulin (8.6%) and anti-islet cell autoantibodies (3.8%). Bivariate analysis showed that the positive group had higher fasting glucose, higher glycated hemoglobin (HbA1c), lower C-peptide levels, and a higher number of HLA-matches. Analyzing the sample divided into four groups according to pre-/post-transplant autoantibodies profile, the negative/positive group tended to present the higher HbA1c values. Multivariate analysis confirmed the significant association between pancreas autoimmunity and HbA1c and C-peptide levels. Positivity for these autoantibodies pre-transplantation did not influence pancreas survival. The unfavorable glycemic profile observed in the autoantibody-positive SPKT is a matter of concern, which deserves further attention.

    Full Text Available Background. Functional abnormalities of high-density lipoprotein (HDL could contribute to cardiovascular disease in chronic kidney disease patients. We measured a validated marker of HDL dysfunction, nitrated apolipoprotein A-I, in kidney transplant recipients to test the hypothesis that a functioning kidney transplant reduces serum nitrated apoA-I concentrations. Methods. Concentrations of nitrated apoA-I and apoB were measured using indirect sandwich ELISA assays on sera collected from each transplant subject before transplantation and at 1, 3, and 12 months after transplantation. Patients were excluded if they have history of diabetes, treatment with lipid-lowering medications or HIV protease inhibitors, prednisone dose > 15 mg/day, nephrotic range proteinuria, serum creatinine > 1.5 mg/dL, or active inflammatory disease. Sera from 18 transplanted patients were analyzed. Four subjects were excluded due to insufficient data. Twelve and eight patients had creatinine < 1.5 mg/dL at 3 and 12 months after transplantation, respectively. Results. Nitrated apoA-I was significantly reduced at 12 months after transplantation (p=0.039. The decrease in apoA-I nitration was associated with significant reduction in myeloperoxidase (MPO activity (p=0.047. In contrast to apoA-I, nitrated apoB was not affected after kidney transplantation. Conclusions. Patients with well-functioning grafts had significant reduction in nitrated apoA-I 12 months after kidney transplantation. Further studies are needed in a large cohort to determine if nitrated apoA-I can be used as a valuable marker for cardiovascular risk stratification in chronic kidney disease.

    Patients with long dialysis vintage have low cardiac output for various reasons. Although kidney transplantation is known to improve cardiac mortality, patients are sometimes evaluated as contraindicated for transplantation because of cardiac risk. We successfully performed kidney transplantation for a patient with a long dialysis vintage and dilated cardiomyopathy. Sequential (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy suggested that amelioration of uraemia improved cardiac function. Kidney transplantation for patients with severely impaired cardiac function is safe and effective under careful perioperative monitoring irrespective of dialysis vintage. Sequential (123)I-MIBG scintigraphy can be used as an evaluation tool for the improvement in cardiac function.

    The clinical and renal biopsy findings in 3 patients with recurrent focal and segmental glomerulosclerosis (FSG) are reported, as well as the results of a survey among 17 European centers totaling 27 kidney-transplanted children with FSG. From these 27 patients, 10 had recurrent FSG. The duration of the original disease was less than 3 years in 9 of them. In contrast, this rapid progression of the disease was observed in only 7 of 17 patients in the group without recurrences. Heavy proteinuria was noted within the 1st day, or week, in all but 2 patients where it was detected at 3 and 7 weeks. All developed the nephrotic syndrome. From the 10 kidneys (mostly from cadaver donors) which functioned for more than 1 month, 5 were lost 2--24 months after transplantation because of recurrence (3 patients) or infection (2 patients). It appears that the risk of recurrence can best be predicted by the duration of the original disease: 50% or more if the duration was short (less than 3 years), and only 10--20% when the duration was longer.

    Full Text Available Adenoviruses (AdV are emerging pathogens with a prevalence of 11% viruria and 6.5% viremia in kidney transplant recipients. Although AdV infection is common, interstitial nephritis (ADVIN is rare with only 13 biopsy proven cases reported in the literature. We report a case of severe ADVIN with characteristic histological features that includes severe necrotizing granulomatous lesion with widespread tubular basement membrane rupture and hyperchromatic smudgy intranuclear inclusions in the tubular epithelial cells. The patient was asymptomatic at presentation, and the high AdV viral load (quantitative PCR>2,000,000 copies/mL in the urine and 646,642 copies/mL in the serum confirmed the diagnosis. The patient showed excellent response to a combination of immunosuppression reduction, intravenous cidofovir, and immunoglobulin therapy resulting in complete resolution of infection and recovery of allograft function. Awareness of characteristic biopsy findings may help to clinch the diagnosis early which is essential since the disseminated infection is associated with high mortality of 18% in kidney transplant recipients. Cidofovir is considered the agent of choice for AdV infection in immunocompromised despite lack of randomized trials, and the addition of intravenous immunoglobulin may aid in resolution of infection while help prevention of rejection.

    The course of 16 patients with segmental and focal glomerulosclerosis (SFGS) with kidney transplantation is reported. Ten out of 16 (group I) had the diagnosis histologically confirmed in their native kidneys. In 6 (group II) the diagnosis was suggested by the early development of SFGS in the graft and was considered a recurrence of the baseline disease. The recurrence (in group I) was 40% and the main clinical parameter was proteinuria, in nephrotic level, with early development in all cases (less than 60 days). In those patients who had an early development of the baseline disease (less than 4 years) the recurrence was greater, observed in 5 out of 8 grafts with 3 grafts lost due to the recurrence of focal glomerulosclerosis. On the other hand, the patients whose baseline disease had a longer period of development presented a better course of the recurrent glomerulosclerosis and no grafts were lost in this cases. We believe that renal transplantation of a live donor must be avoided in those patients with quick developing SFGS.

    Full Text Available Sickle cell nephropathy (SCN is a common complication of sickle cell disease (SCD. It has variable presentation, ranging from hyposthenuria to end-stage renal disease (ESRD. Management of ESRD in SCD patients is froth with multiple challenges which has potential to impact negatively the outcome of the patient. Kidney transplant is the preferred renal replacement therapy in these patients. The objective of this case study is to report kidney transplant in a Nigerian young man with sickle cell nephropathy and to highlight the outcome and the challenges to kidney transplant in this patient. The index case is a 26-years-old sickle cell disease patient with ESRD complicated with cardiovascular, pulmonary, immunological, and infective challenges. These conditions were controlled, and the patient had a successful live-related kidney transplant. Kidney transplant is a viable option for sickle cell disease patients with ESRD.

    The effect of nephronic mass reduction of kidney transplants has not been analyzed specifically in a large cohort. Transplant injuries in cadaver kidney graft may have led to an underestimation of the magnitude of this factor. The aim of this study was to analyze the consequences of kidney mass reduction on transplantation outcome. The weights of 1142 kidney grafts were collected prospectively immediately before grafting. Donors and recipients /=4 g/kg). Next, using a Cox model analysis, it was shown that the risk of having a proteinuria >0.5 g/kg was significantly increased for the low DKW/RBW ratios /=4 g/kg (P < 0.001). In cadaver transplant recipients, graft mass has a rapid impact on graft filtration rate and proteinuria. Avoiding major kidney/recipient inadequacy should have a significant influence on long-term transplant function.

    As fertility is restored after renal transplant, more female recipients of a renal transplant successfully complete pregnancies that are safe for the mother, the fetus, and the renal allograft. Although the transplanted kidney lies in one of the iliac fossae, normal vaginal delivery is not impeded by this positioning. Caesarean section is indicated in many scenarios, primarily for obstetric reasons, particularly when the transplanted kidney lies in a position where it could be injured. Here, we report our experiences managing a rare instance of injury to a transplanted kidney during caesarean section and discuss the relevant aspects of its management. To our knowledge, this is the first report in the English literature of an injury to a transplanted kidney during caesarean section.

    Kidney transplantation (Ktx) is generally performed during end stage renal disease due to a loss of the kidneys' ability to filter wastes from the circulatory system. Acute graft-versus-host disease (GVHD) after Ktx is a life-threatening complication that progresses to organ failure, systemic complications, and death. The current study evaluated the significance of histologic findings of GVHD as obtained from skin biopsies following Ktx in swine. A swine model of Ktx with tacrolimus-based immunosuppression was used to assess possible correlations between acute-graft-cellular rejection and skin histological findings for prediction of GVHD. Animals were divided into a Ktx treatment group or a control group with no Ktx and skin and kidney biopsies were histologically assessed at postoperative days 0, 15, 30, 45 and 60. Skin samples were analyzed and classified from grade 1 to 4 of skin GVHD and the major histopathological changes of kidney acute cellular rejection were described using Banff's score system. We observed a significant linear correlation between the histological grading values of skin biopsy changes and the histological grading values of kidney biopsies (Kendall's tau_b=0.993) in the Ktx experimental group. No histological changes were observed in controls. Our findings demonstrate the diagnostic value of staging skin GVHD after Ktx and suggest it's future utility for monitoring long term Ktx-induced changes.

    Full Text Available To evaluate the feasibility of simultaneous unilateral nephrectomy with kidney transplantation and to determine the effect of this procedure on perioperative morbidity and mortality and graft and patient survival.Between January 2000 and May 2015, 145 patients with autosomal dominant polycystic kidney disease (ADPKD underwent kidney transplantation. Of those, 40 (27.5% underwent concurrent ipsilateral native nephrectomy (group NT. Patients in group NT were compared with patients with ADPKD not undergoing concurrent nephrectomy (group NT- and asymptomatic patients undergoing pretransplant nephrectomy (group PNT.The average follow-up was 66 months. The graft survival rate at 1 and 5 years was 95% and 87.5% versus 93% and 76.2% in the NT and NT- groups, respectively (P = .903 and P = .544, respectively; 1-year patient survival was 100% for NT and 97% for NT- patients (P = .288, whereas 5-year patient survival was 100% and 92% for NT and NT- groups, respectively (P = .128. After propensity score matching (34 patients per group no significant differences were observed in 1-year (97.1% in NT and 94.1%; P = 1 and 5-year (88.2% in NT and 91.2% in NT-; P = 1 graft survival, and in 1-year (100% for both groups; P = 1 and 5-year (100% in NT and 94.1% in NT-; P = 1 patient survival. Perioperative mortality was 0% among NT and 1.2% among NT- patients, whereas perioperative surgical complications were similar in both groups. One- and 5-year graft and patient survival were similar between the NT and PNT groups, but patients in the PNT group had significantly lower levels of hemoglobin and residual diuresis volumes at the time of transplant. Moreover, PNT patients had a longer pretransplant dialysis and a longer time on the waiting list.Simultaneous unilateral nephrectomy does not have a negative effect on patient and graft survival in patients with ADPKD and is associated with low morbidity.

At ESRD start, patients were classified into those with or without contraindications using Canadian eligibility criteria. Based on referral for transplantation, patients were grouped as CANDIDATE (no contraindication and referred, NEITHER (no contraindication and not referred and CONTRAINDICATION. The Charlson Comorbidity Index (CCI was used to assess comorbidity burden. Results Of the 437 patients, 133 (30.4% were CANDIDATE (mean age 50 and CCI 3.0, 59 (13.5% were NEITHER (age 76 and CCI 4.4, and 245 (56.1% were CONTRAINDICATION (age 65 and CCI 5.5. Age was the best discriminator between NEITHER and CANDIDATES (c-statistic 0.96, P P Conclusions There exists a relatively small population of incident patients not referred who have no contraindications. These are older patients with significant comorbidity who have a small window of opportunity for kidney transplantation.

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

    Objective:To establish a sensitized canine model for kidney transplantation. Methods:12 male dogs were averagely grouped as donors and recipients. A small number of donor canine lymphocytes was infused into different anatomic locations of a paired canine recipient for each time and which was repeated weekly. Specific immune sensitization was monitored by means of Complement Dependent Cytotoxicity (CDC) and Mixed Lymphocyte Culture (MLC) test. When CDC test conversed to be positive and MLC test showed a significant proliferation of reactive lymphocytes of canine recipients, the right kidneys of the paired dogs were excised and transplanted to each other concurrently. Injury of renal allograft function was scheduled determined by ECT dynamic kidney photography and pathologic investigation. Results :CDC test usually conversed to be positive and reactive lymphocytes of canine recipients were also observed to be proliferated significantly in MLC test after 3 to 4 times of canine donor lymphocyte infusions. Renal allograft function deterioration occurred 4 d post-operatively in 4 of 6 canine recipients, in contrast to none in control dogs. Pathologic changes suggested antibody-mediated rejection (delayed) or acute rejection in 3 excised renal allograft of sensitized dogs. Seven days after operation, all sensitized dogs had lost graft function, pathologic changes of which showed that the renal allografts were seriously rejected. 2 of 3 dogs in control group were also acutely rejected. Conclusion:A convenient method by means of repeated stimulation of canine lymphocyte may induce specific immune sensitization in canine recipients. Renal allografts in sensitized dogs will be earlier rejected and result in a more deteriorated graft function.

    In recent years, black fungi have been increasingly reported as causing opportunistic infections after solid organ transplantation. Here, we report a case of insidious, relentless, and multifocal Exophiala xenobiotica infection in a kidney transplant recipient that eventually required multiple surgical excisions along with oral and intravenous antifungal combination therapy using liposomal amphotericin B and posaconazole. We compare the present case with all previously reported cases of Exophiala infection after kidney transplantation.

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

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

    Transplantation is a viable treatment option for failure of most major organs. Within urology, transplantation of the kidney and ureter are well documented; however, evidence supporting transplantation of other urologic organs is limited. Failure of these organs carries significant morbidity, and transplantation may have a role in management. This article reviews the knowledge, research, and literature surrounding transplantation of each of the urologic organs. Transplantation of the penis, testicle, urethra, vas deferens, and bladder is discussed. Transplantation attempts have been made individually with each of these organs. Penile transplantation has only been performed once in a human. Testicular transplantation research was intertwined with unethical lucrative pursuits. Interest in urethra, bladder, and vas deferens transplantation has decreased as a result of successful surgical reconstructive techniques. Despite years of effort, transplantations of the penis, testicle, urethra, vas deferens, and bladder are not established in current practice. Recent research has shifted toward techniques of reconstruction, tissue engineering, and regenerative medicine.

    Under the Universal Health Care Program of the Department of Health, the Philippine Health Insurance Corporation (PHIC) launched the Case Type Z benefit package for kidney transplantation, providing the largest amount (USD $13,300.00) for any single medical procedure. The objective of this study was to describe under the PHIC Case Type Z Benefit Package for kidney transplantation at the National Kidney and Transplant Institute and kidney transplantation outcomes under this package. Included in the benefit were standard risk recipients between 10 and 70 years of age with at least 1 human leukocyte antigen (HLA) DR match with the donor, panel-reactive antibody (PRA) less than 20%, and absence of donor-specific antibody (DSA). Previous transplantations, malignancy, hepatitis B and C, human immunodeficiency virus (HIV) positivity, cytomegalovirus (CMV) R-/D+, congestive heart failure, and liver cirrhosis were exclusion criteria. Patients were evaluated by a medical social worker according to their family's financial status. Since June 2012, a total of 261 patients have received the benefit, with 44 under service, 37 with fixed co-pay and 180 with variable co-pay. Of the living donor kidney transplants, 98% had immediate graft function, with 2.3% (6/261) acute rejection rates at 1 year. The total cost of hospitalization was within the benefit for living donor kidney transplants (less than USD 8000.00) but exceeded it in all cases of deceased donor kidney transplants. The successful use of and excellent outcomes under the Case Type Z benefit demonstrated how collaboration among government agencies, health care providers, and pharmaceutical companies could result in a program that improved the access to health care for Filipino patients with end-stage renal disease.

    Background. The calcimimetic, cinacalcet, is approved for treating secondary hyperparathyroidism (SHPT) in patients with chronic kidney disease (CKD) on dialysis. Biochemical profiles and clinical outcomes in patients discontinuing cinacalcet at kidney transplantation have not been previously described. Methods. We performed a retrospective observational study evaluating post-transplant biochemical profiles and clinical outcomes in patients who had enrolled in phase 2 or 3 randomized, placebo-controlled studies of cinacalcet before receiving a kidney transplant. Results. The study included 28 former cinacalcet and 10 former placebo patients. Post-kidney transplant, there were no obvious differences between the two groups in levels of serum intact parathyroid hormone, calcium or phosphorus. One patient in each group underwent post-transplant parathyroidectomy. Kidney transplant failure was apparent in one former cinacalcet-treated patient (4%) and three former placebo patients (30%). The duration of hospitalization (mean ± standard error) immediately post-transplant in these two groups was 2.3 ± 0.3 and 3.4 ± 0.8 weeks, respectively. Conclusions. Using cinacalcet to treat SHPT in patients with CKD awaiting kidney transplantation does not appear to modify SHPT-related post-transplant biochemical profiles, or clinical outcomes, compared with placebo.

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

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

    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.

  4. The impact and treatment of obesity in kidney transplant candidates and recipients

    The prevalence of obesity in patients with chronic kidney failure and renal transplant candidates has paralleled the epidemic in the general population. The associated risks of surgical complications and long-term cardiovascular death are significant: most transplant centers consider obesity a relative contra-indication for transplant. Few studies have focused on conservative weight loss strategies in transplant patients. Studies using administrative databases have found that only a minority ...

    Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). Kidney transplantation recipients live longer and have better quality of life than patients on dialysis. Hypothalamic gonadal dysfunction in females who have ESRD may be reversed within the first few months after kidney transplantation, such as the ability to have children. Despite thousands of successful pregnancies in transplantation recipients, there is limited information about it. In this study, we evaluated the pregnancy rates and live birth rates in women (n = 133) who underwent kidney transplantation in our center from 1983 to 2010. Recipients of a second kidney transplantation and recipients of multiorgan transplantations were excluded. We observed 33 pregnancies with 11 live births (33.3%), 12 spontaneous abortions (36.36%), and 10 therapeutic abortions (30.3%). The pregnancy rate was 18%. The live birth rate was 33.3%. Therapeutic abortions were 36.3%, and the pregnancies resulting in fetal loss were 30.3%. The pregnancies were identified in 32 women. The majority of women (n = 32; 96.9%) had a single pregnancy, whereas 1 woman (3.1%) had two pregnancies. In our series, the pregnancy rates for kidney transplantation recipients were markedly lower and decreased more rapidly than those reported in the general population.

    Full Text Available Kidney transplantation (KT is one of the treatment options for patients with chronic kidney disease. The number of patients waiting for kidney transplantation is growing day by day. Various strategies have been put in place to expand the donor pool. Extended criteria donors are now accepted more frequently. Increasing number of elderly donors with age > 60 years, history of diabetes or hypertension, and clinical proteinuria are accepted as donor. Dual kidney transplantation (DKT is also more frequently done and experience with this technique is slowly building up. DKT not only helps to reduce the number of patients on waiting list but also limits unnecessary discard of viable organs. Surgical complications of DKT are comparable to single kidney transplantation (SKT. Patient and graft survivals are also promising. This review article provides a summary of evidence available in the literature.

    To assess the influence ofcyclosporin A (CsA) and tacrolimus (FK506) on mycophenolic acid (MPA) and correlation analysis of the pharmacokinetic parameters and patient characteristics, clinical outcome in Chinese kidney transplant recipients,the pharmacokinetics of 1000 mg mycophenolate mofetil (MMF) twice daily was measured by high-performance liquid chromatography (HPLC). PKS (Pharmaceutical Kinetics Software) 1.0.2 software package was used for the calculation of pharmarespectively. The level of AUC(0-12) in the FK506 group was significantly higher than that in the CsA group. MPA appeared not to be affected by renal function. MPA AUC(0-12) showed statistically significant difference according to the patient's gender.

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

    Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits). Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

    As universal coverage for pediatric kidney transplantation (KT) was introduced in Thailand in 2008, the number of recipients has been increasing. We evaluated predictive factors for graft failure to understand how to improve clinical outcomes in these children. Using data obtained from the National Transplant registry, we assessed the risk of graft failure using the Kaplan-Meier method and Cox proportional hazards regression. Altogether, 201 recipients aged <21 yr at the time of KT were studied. Living donors (LD) were significantly older than deceased donor (DD). Mean cold ischemia time of DD was 17 h. The mean donor glomerular filtration rate (GFR) was 84.0 mL/min/1.73 m(2) . Induction immunosuppressive therapy was administered more frequently in DD than in LDKT. Delayed graft function (DGF) occurred in 36 transplants. Over 719 person years of follow-up, 42 graft failures occurred. Graft survival at one, three, and five yr post-transplant were 95%, 88% and 76%, respectively. Two factors independently predicted graft failure in multivariate analysis. The hazard ratios for graft failure in patients with DGF and in patients with donor GFR of ≤30 mL/min/1.73 m(2) were 2.5 and 9.7, respectively. Pediatric recipients should receive the first priority for allografts from young DD with a good GFR, and DGF should be meticulously prevented.

    Delayed graft function in kidney transplant recipients is a known complication associated with increased risk of acute rejection and reduced transplant survival after 1 year. There are multiple risk factors, including prolonged cold ischemia time, donor age, and cause of donor's death. Major causes of delayed graft function are acute kidney injury in the donor, often from prolonged terminal ischemia, reflected by acute tubular injury in the recipient. However, the differential diagnosis of delayed graft function includes acute rejection, recurrence of the primary glomerular diseases, and other less commonly encountered conditions. A transplant kidney biopsy usually is required to elucidate the correct cause and initiate the right treatment, which is crucial for transplant survival. We report a case of a transplant recipient who developed delayed graft function due to an uncommon cause. After correct diagnosis, the patient's transplant function improved.

    HIV-positive patients with end stage chronic kidney disease requiring dialysis is progressively growing. Kidney transplantation, previously considered as absolute contraindication for HIV-infected patients is currently, in the HAART era, considered a possible treatment alternative. Concerns for the effects of immunosuppressive drugs in these patients and the possible effects on progression of HIV disease, in addition to the risk of opportunistic infections and cancer development are widely discussed. Clinical experience in the HAART era shows that use of immunosuppressive drugs does not adversely affect HIV-seropositive patients. Furthermore, several transplant centers have reported improved patient and graft outcomes for kidney transplant recipients infected with HIV. In summary, results obtained so far are encouraging, supporting that renal transplantation, following specific selection criteria, can be considered an alternative of renal replacement therapy in HIV-infected patients.

    Objective. To investigate the difference of rejection in single versus combined pancreas and kidney transplantation in rats. Methods. Allograft models including simultaneous pancreas and kidney(SPK) transplant and pancreas or kidney transplant alone were established in SD-Wistar rats, rejections of pancreas and kidney in different models were com-pared morphologically and functionally. Results. Mean survival time (MST) of pancreas was significantly prolonged in SPK than in pancreas transplant alone (PTA) (11.5 days vs. 9.2 days, P <0.05). Incidence of interstitial pancreatic rejection at grade Ⅱ and grade Ⅲ was much obvious in PTA than in SPK (42.9% vs. 12.5% at grade Ⅱ and 28.6% vs 6.3% at grade Ⅲ , P<0.05). No significant difference was found in MST between SPK and kidney transplant alone(KTA). Administration of cyclesporine A prolonged the MST of pancreas and kidney, without altering the tendency stated above. Condusions. In SPK, the function of pancreas is protected by kidney hence the severity of rejection is reduced, whereas the function of kidney is not protected by pancreas. It suggests that different organs differ in immunoaller-gization and immunoregulation, and immune response tend to attack organs with greater immunoactivity, those organs with minor one could be protected. Cyclesporine A is effective on prolonging the MST of pancreas and kidney.

    Objective. To investigate the difference of rejection in single versus combined pancreas and kidney transplantation in rats. Methods. All ograft models including simultaneous pancreas and kidney(SPK)transplant and pancreas or kidney transplant alone were established in SD-Wistar rats, rejections of pancreas and kidney in different models were com pared morphologically and functionally. Results. Mean survival time (MST)of pancreas was significantly prolonged in SPK than in pancreas transplant alone(PTA)( 11.5 days vs. 9.2 days, P < 0.05). Incidence of interstitial pancreatic rejection at grade Ⅱ and grade Ⅲ was much obvious in PTA than in SPK(42.9% vs. 12.5% at grade Ⅱ and 28.6% vs 6.3% at grade Ⅲ , P < 0.05). No significant difference was found in MST between SPK and kidney transplant alone(KTA). Administration of cyclosporine A prolonged the MS T of pancreas and kidney, without altering the tendency stated above. Conclusions. In SPK, the function of pancreas is protected by kidney hence the severity of rejection is reduced, whereas the function of kidney is not protected by pancreas. It suggests that different organs differ in immunoaller gization and immunoregula tion, and immune response tend to attack organs with greater immunoactivity, those organs with minor one could be protected. Cyclosporine A is effective on prolonging the MST of pancreas and kidney.

    Background The number of highly sensitized patients is rising, and sensitization can lead to renal transplant failure.The present study aimed to investigate the safety and efficacy of renal transplantation following induction therapy with rituximab in highly sensitized kidney transplant recipients.Methods Seven highly sensitized kidney transplant recipients who underwent rituximab therapy from December 2008 to December 2009 were retrospectively analyzed. There were 3 men and 4 women, with a mean age of 38.5 years (range, 21-47 years). The duration of hemodialysis was 3-12 months, with a mean duration of 11 months. For 4 patients,this was the second transplant; the previous graft survival time was 2-11 years, with a mean survival time of 5.8 years. All the female recipients had history of multiple pregnancies, and all patients had previously received blood transfusions. All donors were men, with a mean age of 32.5 years (range, 25-37 years). In 2 of the 7 patients, both class I and class II of panel reactive antibody were high; the remaining 5 patients showed either high in class I or in class II of panel reactive antibody. The mean panel reactive antibody value was 31% for class I and 51% for class II respectively. The donors and the recipients had the same blood type, with low lymphocyte cytotoxicity ranging from 2% to 5%. The human leukocyte antigen (HLA) mismatch numbers were from 2 to 4. All patients received tacrolimus (0.1 mg·kg-1·d-1) and mycophenolate mofetil (750 mg twice per day) orally 3 days prior to surgery. All patients received a single dose of 600 mg rituximab (375 mg/m2) infusion on the day before surgery and polyclonal antibody (antithymocyte globulin) on the day of surgery.Postoperative creatinine, creatinine clearance rate, and occurrence of rejection by pathological biopsy confirmation were monitored.Results No patient had delayed graft function after surgery. Two patients had acute rejection, one on day 7 and the other on day 13 post

    The discussion of compensating for shortages of cadaveric donation with increased living donation often reveals differences between the Scandinavian countries and Germany. Possible adoption of Scandinavian structures to improve the rate of living donations in Germany warrants analysis of the actual differences between these two regions. Close examination reveals that significantly higher rates of living donation are achieved only in Sweden and Norway. In Norway, a frequently postulated negative effect on cadaveric donation due to very high rates of living donation could not be confirmed. In contrast to Germany and as a consequence of Norwegian geography, kidney transplantation has been regarded in Norway as the first-line therapy for endstage renal disease for more than 35 years. Living donation has since been actively pursued and is traditionally the transplantation of first choice. In Germany, living donation is still regarded as the second choice after cadaveric donation, due to legal regulations. Significant improvements in living donation frequencies could be achieved there by adopting the active Norwegian approach to living donor identification.

    To investigate the gene expression profiles in acute allograft rejection of renal trans- plantation, and identify the markers for the early diagnosis of acute rejection, heterotopic kidney transplantation was performed by using F344 or Lewis donors and Lewis recipients. No immunosup- pressant was used. Renal grafts were harvested on days 3, 7, and 14. A commercial microarray was used to measure gene expression levels in day-7 grafts. The expression levels of 48 genes were up-regulated in the allograft in comparison with the isograft control, and interferon-y-induced GTPase gene was most significantly up-regulated in allografts. It is concluded that a variety of pathways are involved in organ transplant rejection which is dynamic and non-balanced. IFN-inducible genes, such as IGTP, may play an important role in the rejection. A lot of important factors involved in acute re- jection are unnecessary but sufficient conditions for the rejection. We are led to conclude that it is virtually impossible to make an early diagnosis based on a single gene marker, but it could he achieved on the basis of a set of markers.

    Full Text Available Background/Aims: Cardiac changes observed in chronic kidney disease patients are of multifactorial origin including chronic uremia, hemodynamics or inflammation. Restoration of renal function by kidney transplantation (KTX may reverse cardiac changes. Novel echocardiographic methods such as speckle tracking echocardiography (STE allow early and sensitive detection of subtle changes of cardiac parameters. We evaluated changes of cardiac structure and function after KTX by advanced echocardiographic modalities. Methods: Thirty-one KTX recipients (female n=11 were evaluated by medical examination, laboratory testing and echocardiography before and after KTX (median follow-up 19 months. Left ventricular (LV and right ventricular (RV diameters and function were assessed by echocardiographic standard parameters. Longitudinal 2D strain of the LV (GLPS and left atrium (LA was determined by 2D STE. Results: After KTX, median serum creatinine level was 1.3 mg/dl (IQR, 1.2-1.5. Systolic blood pressure decreased significantly after KTX. Echocardiography showed a significant reduction in LV end-diastolic septal and posterior wall thickness and LV mass index after KTX, which was accompanied by an improvement of GLPS. There were no relevant changes in parameters of LA (reservoir, conduit or contractile function, LV diastolic or RV function after KTX. Conclusion: LV hypertrophy reversed after successful KTX and was accompanied by an improvement in longitudinal LV function as assessed by STE. Diastolic function and STE-derived LA function parameters did not change significantly after KTX.

    Major urological complications (MUCs) after kidney transplantation contribute to patient morbidity and compromise graft function. The majority arise from the vesico-ureteric anastomosis and present early after transplantation. Ureteric stents have been successfully used to treat such complications. A number of centres have adopted a policy of universal prophylactic stenting, at the time of graft implantation, to reduce the incidence of urine leaks and ureteric stenosis. Stents are associated with specific complications and some centres advocate a policy of only stenting selected anastomoses. To examine the benefits and harms of routine ureteric stenting to prevent urological complications in kidney transplant recipients. We searched the Cochrane Central Register of Controlled Trials (CENTRAL in The Cochrane Library), MEDLINE, EMBASE, reference lists of articles, books and abstracts and contacted companies, authors and experts to identify relevant randomised controlled trials (RCTs). All RCTs and quasi-RCTs were included in our meta-analysis. Four reviewers assessed the trials for quality against four criteria (allocation concealment, blinding, intention-to-treat and completeness of follow-up). The primary outcome was the incidence of MUCs. Further outcomes of interest were graft and patient survival and the incidence of adverse events (urinary tract infection (UTI), haematuria, irritative symptoms, pain and stent migration). Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) with 95% confidence intervals (CI). Seven RCTs (1154 patients) of low or moderate quality were identified. The incidence of MUCs was significantly reduced (RR 0.24, 95% CI 0.07 to 0.77, P = 0.02, NNT 13) by universal prophylactic stenting. This was dependent on whether the same surgeon performed, or was in attendance, during the operations. Two patients lost their grafts to infective urinary tract complications in the stented group

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

    Combined kidney-pancreas transplantation is the treatment of choice for end-stage diabetic nephropathy. Weight gain post-transplant increases the risk for post-transplant complications and death due to cardiovascular events. Gastric pacemakers have been used for therapy of diabetic gastropathy and for the treatment of moderate morbid obesity. We report a patient who experienced significant weight gain following successful kidney-pancreas transplantation and was thereafter successfully treated for diabetic gastroparesis and morbid obesity by use of a laparoscopically implanted gastric pacemaker.

    Conflicting evidence surrounds clinical outcomes in obese individuals after transplantation; nonetheless, many are denied the opportunity to receive a transplant. Allografts with complex vascular anatomy are regularly used in both deceased and living donor settings. We established the risk of transplanting kidneys with multiple renal arteries into obese recipients. A retrospective analysis of data from 1095 patients undergoing renal transplantation between January 2004 and July 2013 at a single centre was conducted. Of these, 24.2% were obese (body mass index >30 kg/m(2)), whereas 25.1% of kidneys transplanted had multiple arteries, thereby making the transplantation of kidneys of complex anatomy into obese recipients a relatively common clinical occurrence. Vessel multiplicity was associated with inferior 1-year graft survival (85.8.% vs 92.1%, P = .004). Obese patients had worse 1-graft survival compared to those of normal BMI (86.8% vs 93.8%, P = .001). The risk of vascular complications and of graft loss within a year after transplantation were greater when grafts with multiple arteries were transplanted into obese recipients as compared to their nonobese counterparts (RR 2.00, CI 95% 1.07-3.65, and RR 1.95, CI 95% 1.02-3.65). Additionally, obese patients faced significantly higher risk of graft loss if receiving a kidney with multiple arteries compared to one of normal anatomy (RR 1.97, 95% CI 1.02-3.72). Thus, obese patients receiving complex anatomy kidneys face poorer outcomes, which should be considered when allocating organs, seeking consent, and arranging for aftercare.

    2012-01-01

    A meta-analysis of odds ratios comparing the risks of participating in transplant tourism by acquiring a kidney abroad to the risks associated with domestic kidney transplant was undertaken. Comparison across 12 medical outcomes indicates transplant tourists are significantly more likely to contract cytomegalovirus, hepatitis B, HIV, post-transplantation diabetes mellitus, and wound infection than those receiving domestic kidney transplant. Results also indicate that domestic kidney transplant recipients experience significantly higher one-yr patient- and graft-survival rates. Analyses are supplemented by independent comparisons of outcomes and provide practitioners with weighted estimates of the proportion of transplant recipients experiencing 15 medical outcomes. Practitioners are encouraged to caution patients of the medical risks associated with transplant tourism. Despite the illegal and unethical nature of transplant tourism, additional efforts are indicated to eliminate the organ trade and to educate wait-listed patients about the risks of transplant tourism.

    Clinicians commonly search bibliographic databases such as Medline to find sound evidence to guide patient care. Unfortunately, this can be a frustrating experience because database searches often miss relevant articles. We addressed this problem for transplant professionals by developing kidney transplantation search filters for use in Medline through PubMed and Ovid Technologies, and Embase. We began by reading the full-text versions of 22,992 articles from 39 journals published across 5 years. These articles were labeled relevant to kidney transplantation or not forming our "gold standard." We then developed close to five million kidney transplantation filters using different terms and their combinations. Afterward, these filters were applied to development and validation subsets of the articles to determine their accuracy and reliability in identifying articles with kidney transplantation content. The final kidney transplantation filters used multiple terms in combination. The best performing filters achieved 97.5% sensitivity (95% confidence interval, 96.4%-98.5%), and 98.0% specificity (95% confidence interval, 97.8%-98.3%). Similar high performance was achieved for filters developed for Ovid Medline and Embase. Proof-of-concept searches confirmed more relevant articles are retrieved using these filters. These kidney transplantation filters can now be used in Medline and Embase databases to improve clinician searching.

    Full Text Available Chronic kidney disease has direct implications in nutritional status, causing anorexia and muscular catabolism. These situations are frequent in kidney renal replacement therapy in which nutritional disorders and inflammatory mechanisms associated with therapy often lead to the development of protein-energy wasting. Nutrition therapy has shown an adequate therapeutic strategy to prevent and treat metabolic alterations, reducing surgical and nutritional complication risks in kidney transplantation patients. The current case reports nutritional intervention on a continuous ambulatory peritoneal dialysis patient who was subsequently prescribed to automatic peritoneal dialysis and, finally, kidney transplant from a living donor.

    Here we introduce a novel method of transplanting human fetal kidneys into adult rats. To overcome the technical challenges of fetal-to-adult organ transplantation, we devised an arterial flow regulator (AFR), consisting of a volume adjustable saline-filled cuff, which enables low-pressure human fetal kidneys to be transplanted into high-pressure adult rat hosts. By incrementally withdrawing saline from the AFR over time, blood flow entering the human fetal kidney was gradually increased until full blood flow was restored 30 days after transplantation. Human fetal kidneys were shown to dramatically increase in size and function. Moreover, rats which had all native renal mass removed 30 days after successful transplantation of the human fetal kidney were shown to have a mean survival time of 122 days compared to 3 days for control rats that underwent bilateral nephrectomy without a prior human fetal kidney transplant. These in vivo human fetal kidney models may serve as powerful platforms for drug testing and discovery.

    Increasing use of kidney grafts for simultaneous liver and kidney (SLK) transplants is causing concern about the most effective utilization of scarce kidney graft resources. This study evaluated the impact of implementing the proposed United Network for Organ Sharing SLK transplant policy on outcomes for end-stage liver disease (ESLD) and end-stage renal disease (ESRD) patients awaiting transplant. A Markov model was constructed to simulate a hypothetical cohort of ESLD patients over a 30-year time horizon starting from age 50. The model applies the different criteria being considered in the United Network for Organ Sharing policy and tallies outcomes, including numbers of procedures and life years after liver transplant alone (LTA) or SLK transplant. When 1-week pretransplant dialysis duration is required, the numbers of SLK transplants and LTAs would be 648 and 9,065, respectively. If the pretransplant dialysis duration is extended to 12 weeks, there would be 240 SLK transplants and 9,426 LTAs. This change results in a decrease of 6,483 life years among SLK transplant recipients and an increase of 4,971 life years among LTA recipients. However, by increasing the dialysis duration to 12 weeks from 1 week, 408 kidney grafts would be released to the kidney waitlist because of the decline in SLK transplants; this yields 796 additional life years gained among ESRD patients. Implementation of the proposed SLK transplant policy could restore access to kidney transplants for patients with ESRD albeit at the detriment of patients with ESLD and renal impairment.

    The influence of HLA compatibility as well as immediate postoperative function on survival rates was investigated in 203 cadaver kidney transplants. HLA compatibility, especially DR compatibility, improved transplant survival significantly. A direct correlation was found between primary transplant function and long-term results. HLA compatibility and quality of the donor organ had a cumulative effect on kidney transplant survival. Our results are a further indication that besides HLA compatibility, optimal quality of donor organs has crucial significance for the results of transplantation.

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

    Malignancy is a common complication after renal transplantation. However, limited data are available on post-transplant malignancy in living kidney transplantation. Therefore, we made a plan to evaluate the incidence and types of malignancies, association with the main risk factors and patient survival in a large population of living kidney transplantation. We conducted a large retrospective multicenter study on 12525 renal recipients, accounting for up to 59% of all kidney transplantation in Iran during 22 years follow up period. All information was collected from observation of individual notes or computerized records for transplant patients. Two hundred and sixty-six biopsy-proven malignancies were collected from 16 Transplant Centers in Iran; 26 different type of malignancy categorized in 5 groups were detected. The mean age of patients was 46.2±12.9 years, mean age at tumor diagnosis was 50.8±13.2 years and average time between transplantation and detection of malignancy was 50.0±48.4 months. Overall tumor incidence in recipients was 2%. Kaposis' sarcoma was the most common type of tumor. The overall mean survival time was 117.1 months (95% CI: 104.9-129.3). In multivariate analysis, the only independent risk factor associated with mortality was type of malignancy. This study revealed the lowest malignancy incidence in living unrelated kidney transplantation. PMID:22712025

  13. Hypertension and obesity after pediatric kidney transplantation: management based on pathophysiology: A mini review

    Directory of Open Access Journals (Sweden)

    Eunice G John

    2014-01-01

    Full Text Available Hypertension after pediatric renal transplant is a common and important risk factor for graft loss and patient survival. The mechanism of post kidney transplant hypertension is complex and multifactorial. Control of blood pressure in renal transplant patients is important but often times blood pressures remain uncontrolled. The management of hypertension and obesity in pediatric kidney transplant patients is based on the pathophysiology. Compared to the general pediatric hypertensive population, special attention needs to be focused on the additional impact of immunosuppressive medications side effects and interactions, recurrent disease, and donor and recipient comorbidities such as obesity on blood pressure control with thoughtful consideration of the risk of graft failure. In general, there is a need for prospective studies in pediatric kidney transplant patients to understand the pathophysiology of hypertension and obesity and the appropriate approach to achieve a balance between the primary need to avoid rejection and the need to lower blood pressure and prevent obesity.

    Case series Patient: Male, 38 • Male, 48 Final Diagnosis: En-bloc transplantation (liver, kidney, pancreas) Symptoms: Encephalopathy • adynamia • ascites • asthenia Medication: — Clinical Procedure: En-bloc transplantation Specialty: Transplantology Objective: Unusual setting of medical care Background: En-bloc transplantation is a surgical procedure in which multiple organs are transplanted simultaneously. It has some similarities with multi-organ transplantation but offers certain advantages. This report highlights the experience of our interdisciplinary group regarding the treatment and follow-up of patients who received en-bloc transplantation, with the aim of encouraging the development of this surgical technique. Case Report: The first case is a 38-year-old patient with type 1 diabetes mellitus, liver cirrhosis, and chronic kidney failure who received an en-bloc transplant of the liver, pancreas, and kidney with no intraoperative complications. He had a prolonged hospital stay due to anemia and systemic inflammatory response syndrome, which were resolved successfully. At follow-up, he had no requirement for insulin or for dialysis, or for new interventions. The second case describes a 48-year-old patient with type 2 diabetes mellitus, renal failure, and liver cirrhosis who received an en-bloc transplant of the liver, pancreas, and kidney with no complications. During the postoperative period, the patient suffered a possible episode of acute tubular necrosis, which evolved towards improvement, with a tendency to normal metabolic and renal functioning, with no additional events. The patient is currently in follow-up and is insulin-independent. Conclusions: En-bloc transplantation is a safe procedure, which is technically simple and which achieves excellent results. This procedure is indicated in patients with end-stage renal disease, cirrhosis, and diabetes mellitus that is difficult to control. PMID:28148909

    The United Network for Organ Sharing (UNOS) implemented a new Kidney Allocation System (KAS) in December 2014 that is expected to substantially reduce racial disparities in kidney transplantation among waitlisted patients. However, not all dialysis facility clinical providers and end stage renal disease (ESRD) patients are aware of how the policy change could improve access to transplant. We describe the ASCENT (Allocation System Changes for Equity in KidNey Transplantation) study, a randomized controlled effectiveness-implementation study designed to test the effectiveness of a multicomponent intervention to improve access to the early steps of kidney transplantation among dialysis facilities across the United States. The multicomponent intervention consists of an educational webinar for dialysis medical directors, an educational video for patients and an educational video for dialysis staff, and a dialysis-facility specific transplant performance feedback report. Materials will be developed by a multidisciplinary dissemination advisory board and will undergo formative testing in dialysis facilities across the United States. This study is estimated to enroll ~600 U.S. dialysis facilities with low waitlisting in all 18 ESRD Networks. The co-primary outcomes include change in waitlisting, and waitlist disparity at 1 year; secondary outcomes include changes in facility medical director knowledge about KAS, staff training regarding KAS, patient education regarding transplant, and a medical director's intent to refer patients for transplant evaluation. The results from the ASCENT study will demonstrate the feasibility and effectiveness of a multicomponent intervention designed to increase access to the deceased-donor kidney waitlist and reduce racial disparities in waitlisting.

    Background: Cytomegalovirus (CMV) infection is a common complication following kidney transplantation. Objective: To assess the incidence and risk factors of CMV infection among renal transplant recipients. Methods: In a retrospective multicenter study, 3065 renal transplant recipients from 17 transplant centers of Iran were studied between April 2008 and January 2011. Kidney transplant patients were routinely monitored by sequential blood samples drawn for use in the CMV-pp65 antigenemia assay, and for hematological and biochemistry tests. Results: 63% of studied patients were males; the mean±SD age of participants was 38±15 years. The majority of cases (81%) received a kidney from a living unrelated donor (LURD), 9% from living related donor (LRD), and 10% from deceased donors. 671 patients experienced CMV viremia. The incidence of CMV infection was 21.9% (95% CI: 20.4%–23.4%). The rate was higher in the first 6 months after transplantation (p<0.001); in recipients with higher level of cyclosporine (p<0.001); in those with lower hemoglobin concentration (p=0.02); patients with elevated ALT (p<0.001); those with increased fasting blood sugar (p=0.005); recipients with dyslipidemia (p<0.05); deceased kidney recipients (p=0.006); and patients with kidney graft impairment (p=0.01). In multivariate regression analysis, time since kidney transplantation (p<0.001) and renal allograft failure (p<0.001) were the only risk factors associated with CMV infection. Conclusions: CMV infection was a common complication in the first 6 months of kidney transplantation, particularly among patients with kidney graft impairment. PMID:25013626

    Liver or kidney transplant recipients are at a higher risk of developing tuberculosis (TB) than general population. We aimed to clarify the incidence density of and risk factors for TB in liver or kidney transplant recipients in the present study. All patients with TB following liver or kidney transplantation were investigated retrospectively at the Third Xiangya Hospital, Central South University, Changsha, China. The incidence density of TB was calculated. We performed a nested case-control study (1:1) to investigate by univariate and multivariate logistic regression analysis the potential risk factors for TB. From January 2000 to August 2013, 1748 kidney and 166 liver transplant recipients were performed at a university teaching hospital. Among the 1914 recipients, 45 cases (2.4%) of TB were reported. The incidence density was 506 cases per 105 patient-years in kidney or liver transplant recipients, which was 7 times higher than in the general Chinese population (around 70 cases per 105 person-years). The median time to develop TB was 20.0 months (interquartile ratio: 5.0-70.0). The receipt of a graft from a cadaveric donor (odds ratio [OR] = 3.7; 95% confidence interval [CI] = 1.4-10.0; P = 0.010) and the preoperative evidence of latent TB (OR = 6.8; 95% CI = 2.0-22.7; P = 0.002) were identified as two risk factors for developing TB in liver or kidney transplant recipients. The incidence density of TB among liver or kidney transplant recipients was much higher than in the general Chinese population. Recipients receiving a graft from a cadaveric donor and the preoperative evidence of latent TB were two major risk factors for developing TB in liver or kidney transplant recipients.

    In 2011, a pilot program of organ donation after cardiac death was begun at the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China, where we hosted one of the largest donation after cardiac death organ transplant programs in the country. We report our initial single-center experiences of kidney transplant from donation after cardiac deaths. From January 2011 to July 2013 at our center, 101 kidney transplants from donation after cardiac death donors were performed. The results of kidney transplants from donation after cardiac death donors were compared with those of 50 kidney transplants from donation after brain death performed during the same time. Delayed graft function occurred more frequently in donation after cardiac death than donation after brain death kidneys (16.8% vs 4.0%; P = .035). There was no difference in the incidence of acute rejection between donation after cardiac death and donation after brain death kidneys (10.9% vs 6.0%). Actual 1-year graft survival rate was similar (donation after cardiac death 94.4% vs donation after brain death 96.2%). Estimated glomerular filtration rate at 12 months was similar between donation after cardiac death and donation after brain death kidneys (73.8 ± 20.0 vs 77.8 ± 22.7 mL/min/1.73 m2). Kidney transplants from donation after cardiac death donors have comparable short-term outcomes to kidney transplants from donation after brain death donors. Donation after cardiac death can play a crucial role in overcoming the organ shortage in China.

All recipients were over 55 years old according to the selection criteria. The aim of this study is to assess the quality of life after kidney transplant in this cohort. Methods: From February 2007 to July 2013, 27 patients received a kidney graft after excision of the small kidney tumor. All patients were given the modified 36-Item Short Form Survey (SF-36 questionnaire with additional information regarding concerns about tumor recurrence and whether they would choose TRK transplantation or prefer to stay on dialysis if they have an option again. Results: Of them, 20 returned the completed questionnaire. There is no tumor recurrence on a mean follow-up of 38 months. The mean scores in all eight domains of the SF-36 were higher posttransplantation. The differences were statistically significant. Ninety-five percent of recipients would prefer to have TRK transplantation rather than remain on dialysis. Eighty percent of patients had no or minimal concerns regarding tumor recurrence. Conclusion: The patients who had kidney transplantation by using the graft after excision of a small tumor have achieved excellent quality of life. It is an important alternative for the solution of organ shortage in kidney transplantation. The concern of tumor recurrence is minimal. Performing a further study is worthwhile, with prospective data collection and a control group. Keywords: quality of life, kidney transplant, tumor, small renal cell carcinoma

    Urinary tract infection (UTI) constitutes the most frequent infection among kidney transplantation (KT) patients. The epidemiology and specific risk factors for recurrent UTI after KT have not been well studied. The aim of this work was to assess the incidence, pathogenic spectrum, and risk factors for recurrent post-KT UTI. This observational, cross-sectional study included all patients admitted to our transplantation department with a diagnosis of post-KT UTI from January 2010 to December 2011. Recurring post-KT UTI was defined as ≥ 2 UTIs in 6 months or ≥ 3 UTIs in 12 months. Factors associated with recurrent post-KT UTI were assessed using logistic regression analysis. The 154 patients were diagnosed with 315 episodes of post-KT UTI (28.6%), with recurrent post-KT UTI among 72% of cases. Most recurrent UTIs (73.6%) occurred during the first year after KT. Klebsiella species was the most common isolated pathogen (53.2%), being a serious problem for multidrug-resistance (odds ratio [OR], 13; 95% confidence interval [CI] 5.9-28.6; P recurrent post-KT UTI. KT recipient demographics and characteristics, factors related to KT and urologic complications, did not differ significantly between patients with versus without recurrent post-KT UTI. In conclusion, in a unit where recurrent post-KT UTI incidence was 72% and Klebsiella species was the prevailing uropathogen, nosocomial infection and multidrug-resistant bacteria appeared to be independent predictive factors for recurrent post-KT UTI.

    Background The glomerular filtration rate (GFR) estimating equation incorporating both cystatin C and creatinine perform better than those using creatinine or cystatin C alone in patients with reduced GFR. Whether this equation performs well in kidney transplant recipients cross-sectionally, and more importantly, over time has not been addressed. Methods We analyzed four GFR estimating equations in participants of the Angiotensin II Blockade for Chronic Allograft Nephropathy Trial (NCT 00067990): Chronic Kidney Disease Epidemiology Collaboration equations based on serum cystatin C and creatinine (eGFR (CKD-EPI-Creat+CysC)), cystatin C alone (eGFR (CKD-EPI-CysC)), creatinine alone (eGFR (CKD-EPI-Creat)) and the Modification of Diet in Renal Disease study equation (eGFR(MDRD)). Iothalamate GFR served as a standard (mGFR). Results mGFR, serum creatinine, and cystatin C shortly after transplant were 56.1 ± 17.0 mL/min/1.73 m2, 1.2 ± 0.4 mg/dL, and 1.2 ± 0.3 mg/L respectively. eGFR (CKD-EPI-Creat+CysC) was most precise (R2=0.50) but slightly more biased than eGFR (MDRD); 9.0 ± 12.7 ml/min/1.73m2 vs. 6.4 ± 15.8 ml/min/1.73m2, respectively. This improved precision was most evident in recipients with mGFR >60 ml/min/1.73m2. For relative accuracy, eGFR (MDRD) and eGFR (CKD-EPI-Creat+CysC) had the highest percentage of estimates falling within 30% of mGFR; 75.8% and 68.9%, respectively. Longitudinally, equations incorporating cystatin C most closely paralleled the change in mGFR. Conclusion eGFR (CKD-EPI-Creat+CysC) is more precise and reflects GFR change over time reasonably well. eGFR (MDRD) had superior performance in recipients with mGFR between 30–60 ml/min/1.73m2.

    End-stage renal disease is associated with severe abnormalities in reproductive function. However, the abnormalities are reversed by successful kidney transplantation. The aim of the present study was to compare hormonal levels between recipients with successful kidney transplantations and healthy women with the same gynecologic conditions. The study group consisted of 31 women of reproductive age with end-stage renal disease who underwent successful kidney transplantation. The ratio of the control group, composed of healthy woman, to the study group was 3:1 matched for age and symptoms. Abnormal bleeding (n = 14) and infertility were the most common gynecologic conditions in kidney transplant recipients. The levels of estrogen (E2) and follicle-stimulating hormone (FSH) in the study group were higher than in the control group, but the levels of progesterone (P4) and luteinizing hormone (LH) were lower in the study group than in the control group. There were no significant differences in prolactin and thyroid-stimulating hormone between the two groups. The incidence of infertility in patients who receive steroid was higher than those with no steroid use (P = .007). Compared with healthy age- and symptom-matched women, female kidney transplant recipients have increased levels of E2 and FSH and decreased levels of P4 and LH. These differences in hormone profiles may predispose kidney transplant recipients to increased risk of gynecologic pathologies. Copyright © 2012 Elsevier Inc. All rights reserved.

     Dispositional optimism is a personal resource that determines the coping style and adaptive response to chronic diseases. The aim of this study was to assess the correlations between dispositional optimism and coping strategies in patients with recent kidney transplantation and evaluate the differences in the use of coping strategies in accordance with the level of dispositional optimism.  Patients who were hospitalised in the nephrology department were selected consecutively after kidney transplantation was performed. The evaluation instruments were the Life Orientation Test-Revised, and the Coping Strategies Inventory. The data were analysed with central tendency measures, correlation analyses and means were compared using Student’s t-test.   66 patients with a kidney transplant participated in the study. The coping styles that characterised patients with a recent kidney transplantation were Social withdrawal and Problem avoidance. Correlations between dispositional optimism and coping strategies were significant in a positive direction in Problem-solving (p<.05) and Cognitive restructuring (p<.01), and inversely with Self-criticism (p<.05). Differences in dispositional optimism created significant differences in the Self-Criticism dimension (t=2.58; p<.01).  Dispositional optimism scores provide differences in coping responses after kidney transplantation. Moreover, coping strategies may influence the patient’s perception of emotional wellbeing after kidney transplantation.

    To determine the factors related to immunosuppressant therapy adherence in kidney transplant recipients in Taiwan. Adherence to immunosuppressant treatment is critical after kidney transplantation. Thus, the factors associated with self-reported medication adherence in kidney transplant recipients warrant investigation. The study used a cross-sectional and correlation design. A convenience sample of 145 kidney transplant recipients was included. Structured questionnaires were used to collect data during 2012-2013. Multivariate linear regression was used to examine the factors related to immunosuppressant therapy adherence. Over half of the participants were female (54·5%), mean age was 45·5 years, and mean year after transplant was 7·4. The mean score for medication adherence was 29·73 (possible score range 7-35). The results of the multivariate linear regression analysis showed that gender (male), low income with a high school or college education, years after transplantation and concerns about medication taking were negatively associated with adherence. Medication self-efficacy was positively associated with adherence. Therapy-related factors, partnerships with healthcare professionals and having private healthcare insurance did not significantly relate to immunosuppressant therapy adherence. Kidney transplant recipients demonstrated a high level of adherence. Strategies to enhance patients' self-efficacy and alleviate concerns about medication may promote medication adherence. Male patients, those with a lower income and those with a higher education level, should be a focus of efforts to maintain adherence to the medication regimen. © 2016 John Wiley & Sons Ltd.

    An increasing demand for kidney transplantation has enticed some patients with end-stage renal disease (ESRD) to venture outside their country of residence, but their posttransplant outcomes may be suboptimal. We compared the risks and clinical outcomes among tourists, or patients who pursue a kidney transplant abroad, versus patients who received a transplant at the Toronto General Hospital (TGH). A single-center, 1:3 matched (based on age at transplant, time on dialysis, and year of transplant) cohort study was conducted. Forty-five tourists were matched with 135 domestic transplant recipients between January 1, 2000, and December 31, 2011. Multivariable Cox proportional hazards models were fitted to assess graft and patient outcomes. Among the 45 tourists, the majority (38 of 45) traveled to the Middle East or Far East Asia, and most received living donor kidney transplants (35 of 45). Multivariable Cox proportional hazards models showed that tourists had a higher risk for the composite outcome of acute rejection, death-censored graft failure, or death with graft function (DWGF; hazard ratio [HR] 2.08, 95% confidence interval [CI]: 1.06-4.07). Tourists also showed a higher risk for the individual end points of acute rejection, DWGF, and posttransplant hospitalizations. Patients going abroad for kidney transplantation may have inferior outcomes compared to domestic patients receiving kidney transplants. Patients who are contemplating an overseas transplant need to be aware of the increased risk of adverse posttransplant outcomes and should be appropriately counseled by transplant professionals during the pretransplant evaluation process. © 2016, NATCO.

    The first kidney transplantation (KT) in Uruguay was performed in 1969. We report the rates of KT and survival of patients and grafts up to December 2014. The country has a surface of 176,215 km(2) and a population of 3,286,314 inhabitants (18.6 inhabitants per km(2)). Till December 31, 2014, 1,940 KT have been performed in Uruguay (41.8 pmp that year); 90.4% of them were from cadaveric donors (CD). Median age of recipients (R) was 44 ± 14 years; R older than 55 years increased from 0 to 27% during the period. Our pre-emptive KT program started in 2007. Optimal donors (D) decreased from 65.2% to 35.5%, and D older than 45 years old increased from 9% to 37%. Trauma as cause of death decreased from 49% to 32% and stroke as cause of death increased from 25% to 39%. Patient survival rates at 1, 5, and 8 years were 93%, 87%, and 78%, respectively for KT performed between 1980 and 1989; they were 98%, 93%, and 89%, respectively, for KT performed between 1990 and1999; they were 97%, 91%, and 90%, respectively, for KT performed between 2000 and 2010. In December 2013, there were 1098 patients pmp in renal replacement therapy, 758 pmp in dialysis, and 340 pmp (30.9%) with a functioning graft. Our national KT program is mainly based (90.6%) on cadaveric donation. Epidemiological changes in the characteristics of R and D followed the changes in aging that occurred in the general population and the dialysis population. The survival rates from patients and kidneys are similar to those reported by the European and the American registries.

    Shortage of deceased donors is a severe problem in recent years in China especially in a culture in which brain death criteria is not widely accepted. Donation after cardiac death (DCD) has been reported to expand the donor pool despite higher rates of primary nonfunction (PNF) and delayed graft function (DGF) after transplantation. We collected 71 DCD kidney transplants performed at our hospital between February, 2007 and June, 2012 with aims to demonstrate the feasibility of DCD donation in China. All patients were followed up, and postoperative complications and graft loss were recorded. The PNF rate was 2.8%, and DGF rate was 28.2%. The 1- and 3-year graft survival was 95.7% and 92.4%. In conclusion, graft survival of DCD kidney transplantation in China is excellent despite of higher rates of PNF and DGF after transplantation. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

    A positive pretransplant flow cytometry cross-match (FC-XM) allows precise identification of high-risk recipients vulnerable to hyperacute or accelerated rejection after transplantation. Living donor kidney transplant recipient candidates with positive cross-match have been successfully treated with a combination of plasmapheresis (therapeutic plasma exchange, TPEX) and intravenous immunoglobulin (IVIG), achieving conversion to negative cross-match and successful transplant. We report the first successful case of simultaneous pancreas kidney transplant (SPKT) from a living donor (LD) performed against an initially positive FC-XM, converted to negative using a protocol based on TPEX and IVIG in combination with antiCD20 monoclonal antibody. This strategy of overcoming the cross-match barriers in living donation may offer a chance of successful transplantation to highly sensitized candidates for SPKT, for whom cadaveric transplant is difficult to achieve.

  12. Role of ELISPOT Assays in Risk Assessment Pre- and Post-Kidney Transplantation

    Anat R. Tambur

    2012-05-01

    Full Text Available Immunologic risk in kidney transplantation is typically minimized by avoiding, or at least limiting, the potential of donor specific humoral responses by testing for the presence of donor-specific antibodies (DSA. Additionally, selecting donor and recipient pairs with the least number of human leukocyte antigen (HLA mismatches has been shown to play a role in transplant outcome. However, numerous other factors may play a role in the success of transplant outcome and patient health. Specifically, the use of T-cell allospecific ELISPOT assays have helped elucidate the role of pre-formed cellular responses as additional factors in post-transplant outcome. In this review, we will evaluate numerous uses of ELISPOT assays to assess the pre- and post-transplant immunologic risk of rejection episodes, graft survival and even viral susceptibility as well as the utility of ELISPOT assays in monitoring tolerance and withdrawal of immunosuppressive medications following kidney transplantation.

    Limited data exist regarding the evaluation and selection of older candidates for transplantation. To help guide the development of program protocols and help define research questions in this area, we surveyed U.S. transplant centers regarding their current practices in the evaluation of older kidney transplant candidates. We emailed a 28-question survey to the medical and surgical directors of 190 adult kidney transplant programs in the USA. We received usable responses from 59 programs, a 31.1% response rate. Most (76.3%) programs do not have absolute age cutoffs for listing patients, but for the 22.0% of programs that do have cutoffs, the mean age was 79, range 70-90. Nearly one-third (29.2%) of programs require a minimum life expectancy to list for transplant, reporting a mean of 4.5 years life expectancy, (range 2-10). Programs vary significantly in evaluating candidates living in a nursing home or with cognitive impairments. Practices regarding the evaluation of older transplant candidates vary widely between U.S. programs. Further studies are needed on the impact of age and other comorbidities on transplant outcomes, to help guide decisions on which older patients are most appropriate for transplant listing. © 2017 John Wiley & Sons A/S.

    It has been suggested that dual kidney transplantation (DKT) improves outcomes for expanded criteria donor (ECD) kidneys. However, no criteria for allocation to single or dual transplantation have been assessed prospectively. The strategy of DKT remains underused and potentially eligible kidneys are frequently discarded. We prospectively compared 81 DKT and 70 single kidney transplant (SKT) receiving grafts from ECD donors aged >65 years, allocated according to donor estimated glomerular filtration rate (eGFR): DKT if eGFR between 30 and 60 mL/min, SKT if eGFR greater than 60 mL/min. Patient and graft survival were similar in the two groups. In the DKT group, 13/81 patients lost one of their two kidneys due to hemorrhage, arterial or venous thrombosis. Mean eGFR at month 12 was similar in the DKT and SKT groups (47.8 mL/min and 46.4 mL/min, respectively). Simulated allocation of kidneys according to criteria based on day 0 donor parameters such as those described by Remuzzi et al., Andres et al. and UNOS, did not indicate an improvement in 12-month eGFR compared to our allocation based on donor eGFR.

    Full Text Available Abstract Background Cardiovascular disease (CVD is the major cause of death after renal transplantation. Not only conventional CVD risk factors, but also transplant-specific risk factors can influence the development of CVD in kidney transplant recipients. The main objective of this study will be to determine the incidence of post-transplant CVD after renal transplantation and related factors. A secondary objective will be to examine the ability of standard cardiovascular risk scores (Framingham, Regicor, SCORE, and DORICA to predict post-transplantation cardiovascular events in renal transplant recipients, and to develop a new score for predicting the risk of CVD after kidney transplantation. Methods/Design Observational prospective cohort study of all kidney transplant recipients in the A Coruña Hospital (Spain in the period 1981-2008 (2059 transplants corresponding to 1794 patients. The variables included will be: donor and recipient characteristics, chronic kidney disease-related risk factors, pre-transplant and post-transplant cardiovascular risk factors, routine biochemistry, and immunosuppressive, antihypertensive and lipid-lowering treatment. The events studied in the follow-up will be: patient and graft survival, acute rejection episodes and cardiovascular events (myocardial infarction, invasive coronary artery therapy, cerebral vascular events, new-onset angina, congestive heart failure, rhythm disturbances and peripheral vascular disease. Four cardiovascular risk scores were calculated at the time of transplantation: the Framingham score, the European Systematic Coronary Risk Evaluation (SCORE equation, and the REGICOR (Registre Gironí del COR (Gerona Heart Registry, and DORICA (Dyslipidemia, Obesity, and Cardiovascular Risk functions. The cumulative incidence of cardiovascular events will be analyzed by competing risk survival methods. The clinical relevance of different variables will be calculated using the ARR (Absolute Risk

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

    The Department of Health and Social Security has recently spent over three-quarters of a million pounds advertising the merits of kidney donor cards. The advertising campaign stresses that carrying signed cards requesting the removal of kidneys and other organs after death both increases the number of kidneys available and increases the number of kidney transplants that actually take place. This paper examines the relative success of the kidney donor card campaign in Britain and the nature of the relationship between a more widespread distribution of donor cards and the frequency of kidney transplantation. This is done in two main ways: Through a review of the evidence detailing public support expressed in the media and from social surveys (including original empirical work conducted at Bath University). By an analysis of previously unpublished statistical evidence made available by the Department of Health and Social Security. The paper concludes that the battle for public sympathy towards kidney donation has largely been won and the kidney donor card campaign has been a success. However these success perhaps deflect attention away from more important issues in the transplant equation, as the link between card carrying and increased transplantation is neither direct nor simple.

    Combined liver-kidney transplantation (CLKT) in children is uncommon and outcomes have not been well defined. Using the Scientific Registry of Transplant Recipients, data were analyzed on 152 primary pediatric CLKTs performed from October 1987 to February 2011, to determine their outcome in the largest series reported to date. Patient survival was 86.8%, 82.1% and 78.9% at 1, 5 and 10 years, liver graft survival was 81.9%, 76.5% and 72.6%, and kidney graft survival was 83.4%, 76.5% and 66.8%. By way of comparison, the Registry was queried for pediatric patient survival following isolated liver transplantation (LT) during the same time frame: 86.7%, 81.2% and 77.4% and following isolated kidney transplant (KT): 98.2%, 95.4% and 90% at 1, 5 and 10 years. In patients having undergone CLKT, primary hyperoxaluria was associated with reduced patient (p = 0.01), liver graft (p = 0.01) and kidney graft survival (p = 0.01). Furthermore, graft outcome following CLKT improved over the past decade (p = 0.04 for liver, p = 0.02 for kidney), but this did not translate into improved patient outcome (p = 0.2). All in all, our results confirmed that survival following LT was less than following KT, and that CLKT offered similar patient survival to isolated LT.

    Kidney transplantation in patients with atypical haemolytic uraemic syndrome (aHUS) is frequently complicated by recurrence of aHUS, often resulting in graft loss. Eculizumab prophylaxis prevents recurrence, improving graft survival. An alternative treatment strategy has been proposed where eculizumab is administered upon recurrence. We combined available evidence and performed a cost-effectiveness analysis of these competing strategies. A cost-effectiveness analysis using a decision analytical approach with Markov chain analyses was used to compare alternatives for aHUS patients with end-stage renal disease (ESRD): (i) dialysis treatment, (ii) kidney transplantation, (iii) kidney transplantation with eculizumab therapy upon recurrence of aHUS, (iv) kidney transplantation with eculizumab induction consisting of 12 months of prophylaxis and (v) kidney transplantation with lifelong eculizumab prophylaxis. We assumed that all patients received a graft from a living donor and that recurrence probability was 28.4% within the first year of transplantation. At 8.34 quality-adjusted life years (QALYs) gained and a cost of €402 412, kidney transplantation without eculizumab was the least costly alternative. By comparison, dialysis was more costly and resulted in fewer QALYs gained. Eculizumab upon recurrence resulted in 9.55 QALYs gained at a cost of €425 097. The incremental cost-effectiveness ratio (ICER) was €18 748 per QALY. Both eculizumab induction and lifelong eculizumab were inferior to eculizumab upon recurrence, as both resulted in fewer QALYs gained and higher costs. Kidney transplantation is more cost effective than dialysis to treat ESRD due to aHUS. Adding eculizumab treatment results in a substantial gain in QALYs. When compared with eculizumab upon recurrence, neither eculizumab induction nor lifelong eculizumab prophylaxis resulted in more QALYs, but did yield far higher costs. Therefore, eculizumab upon recurrence of aHUS is more acceptable.

    Background: Few qualitative studies of simultaneous pancreas-kidney transplantation (SPK Tx) have been published. The aims of this study were to explore from the perspective of patients, the experience of living with diabetes mellitus type 1 (T1DM), suffering from complications, and undergoing SPK Tx with good outcome; and to determine the impact of SPK Tx on patients and their social and cultural environment. Methods: We performed a focused ethnographic study. Twenty patients were interviewed. Data were analyzed using content analysis and constant comparison following the method proposed by Miles and Huberman. Results: A functioning SPK Tx allowed renal replacement therapy and insulin to be discontinued. To describe their new situation, patients used words and phrases such as “miracle”, “being reborn” or “coming back to life”. Although the complications of T1DM, its surgery and treatment, and associated psychological problems did not disappear after SPK Tx, these were minimized when compared with the pretransplantation situation. Conclusion: For patients, SPK Tx represents a recovery of their health and autonomy despite remaining problems associated with the complications of T1DM and SPK Tx. The understanding of patients’ existential framework and their experience of disease are key factors for planning new intervention and improvement strategies. PMID:22936846

    AIM To evaluate the incidence of contrast-induced acute kidney injury (CIAKI) in kidney transplant recipients. METHODS A literature search was performed using MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from the inception of the databases through July 2016. Studies assessing the incidence of CIAKI in kidney transplant recipients were included. We applied a random-effects model to estimate the incidence of CIAKI. RESULTS Six studies of 431 kidney transplant recipients were included in the analyses to assess the incidence of CIAKI in kidney transplant recipients. The estimated incidence of CIAKI and CIAKI-requiring dialysis were 9.6% (95%CI: 4.5%-16.3%) and 0.4% (95%CI: 0.0%-1.2%), respectively. A sensitivity analysis limited only to the studies that used low-osmolar or iso-osmolar contrast showed the estimated incidence of CIAKI was 8.0% (95%CI: 3.5%-14.2%). The estimated incidences of CIAKI in recipients who received contrast media with cardiac catheterization, other types of angiogram, and CT scan were 16.1% (95%CI: 6.6%-28.4%), 10.1% (95%CI: 4.2%-18.0%), and 6.1% (95%CI: 1.8%-12.4%), respectively. No graft losses were reported within 30 d post-contrast media administration. However, data on the effects of CIAKI on long-term graft function were limited. CONCLUSION The estimated incidence of CIAKI in kidney transplant recipients is 9.6%. The risk stratification should be considered based on allograft function, indication, and type of procedure.

    Kidney transplantation has become the best treatment for children with chronic kidney disease (CKD). In recent times, knowledge concerning the effect of CKD and kidney transplantation over the normal growth rate has increased; now it is known that 40% of children with CKD do not reach the expected height for age. Growth retardation has been associated with the type of nephropathy, metabolic and endocrine disorders that are secondary to kidney disease, immunosuppressive therapy with glucocorticoids, and suboptimal function of renal allograft. Nowadays, we know better the role of the growth hormone/insulin-like growth factor 1 axis in growth retardation we can see it in children with CKD or recipients of renal allograft. Several studies have shown that administration of recombinant growth hormone (rhGH) has a positive effect on the longitudinal growth of children and teenagers who have received a kidney transplant. On the other hand, there have been reported side effects associated with using rhGH; however, these are not statistically significant. In this article, we show a small review about growth in children with CKD and/or recipients of renal allografts the growth pattern of three children who were known by the Transplant Group of National University of Colombia, and the results obtained with the use of rhGH in one of these cases. We want to show the possibility of achieving a secure use of rhGH in children with CKD and its use as a therapeutic option for treating the growth retardation in children with kidney transplantation, and set out the need of typifying the growth pattern of Colombian children with CKD and/or who are recipients of renal allografts through multicenter studies to propose and analyze the inclusion of rhGH in the therapeutic scheme of Colombian children with these two medical conditions. rhGH could be a useful tool for treating children with CKD or kidney transplantation who have not reached the expected longitudinal growth for age.

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

Neutrophil gelatinase-associated lipocalin (NGAL has been validated as a biomarker for posttransplant acute kidney injury. This observational study aimed to assess the effectiveness of urinary NGAL as a predictive marker of delayed graft function.Materials and methods: Forty-three consecutive patients who received renal transplant were included in the study. Urine samples were collected before transplant (if available and at days 1, 3, 7, 14, and 30 after transplant, and urinary NGAL levels were quantified by enzyme-linked immunosorbent assay.Results: Urinary NGAL progressively decreased after transplant in patients with both delayed and immediate graft function. However, urinary NGAL concentration remained significantly higher in the presence of delayed graft function in the first 14 days after transplant. The area under the receiver operating characteristic curve showed that the ability of urinary NGAL to predict delayed graft function was accurate at 1st and 3rd days after transplant.Conclusion: The relative decrease of urinary NGAL concentration rather than its absolute value may be relevant to predict delayed graft function after renal transplant. In particular, urinary NGAL area under the curve for 3 days seems to be a more valuable parameter of decision making in the early posttransplant period.

    Full Text Available Cefepime is a betalactamic antibiotic used for the treatment of patients with severe infections. It is mainly excreted by the kidney, so that its half-life is significantly increased in patients with kidney failure, and in this population adverse effects may be more severe including neurotoxicity. We report the case of a kidney-transplanted patient who presented neurotoxicity associated with the use of cefepime.

    One way to overcome chronic allograft nephropathy induced by calcineurin inhibitors in immunosuppression protocols for organ transplants is to replace such inhibitors with mammalian target of rapamycin inhibitors, which are not clinically nephrotoxic because they have better renal function. If patients tolerate replacement, there could be a clear preference for mammalian target of rapamycin inhibitors as a maintenance immunosuppressant after renal transplant. This replacement could be sufficient if it were used for a certain time after calcineurin inhibitors. This review considers the conversion effects of calcineurin inhibitors with mammalian target of rapamycin inhibitors from the view point of kidney function during different periods after a kidney transplant.

    The effect of exocrine contamination on islets implanted under the kidney capsule has been studied by histological examination of pure or exocrine-contamination human, monkey, or rat islets transplanted to the kidney capsule of the nude rat, monkey, or rat, respectively. Exocrine contamination resulted in an appearance suggestive of impaired islet implantation, due to tissue necrosis and subsequent fibrosis. The effect of exocrine contamination was examined quantitatively in a rat islet isograft model in which handpicked DA rat islets were transplanted under the kidney capsule of normal DA rats. The islets were either pure or deliberately recontaminated with exocrine tissue (50 or 90% contamination). Four hundred pure islets were placed under one kidney capsule and 400 islets (of similar size and from the same islet preparation) were contaminated and then placed under the contralateral kidney capsule. After 2 weeks the kidneys were removed and extracted for insulin content. The insulin content of kidneys bearing islets contaminated by either 50 or 90% exocrine tissue was significantly reduced when compared to the contralateral kidney bearing pure islets. These findings support the view that exocrine contamination of islets resulted in impaired islet implantation when transplanted to a confined site such as the kidney subcapsule.

    Full Text Available Chronic dialysis hypotension is described as low systolic blood pressure (<100 mmHg during interdialytic period. The presence of low predialysis systolic blood pressure, typically <110 mmHg, is signifi cantly associated with increased mortality. Kidney transplantation is the preferred model of renal replacement therapy in the treatment of end-stage renal disease (ESRD as it improves quality of life and survival. In this article, a long-term hemodialysis (HD patient with chronic hypotension improved after kidney transplantation is presented. A 39-year-old male patient received a deceased donor kidney transplant. The patient was on HD for 23 years. The patient had suffered from chronic persistent hypotension for the last 8 years. Blood pressure was 70/50 mmHg before dialysis and 60/40 mmHg after dialysis. In the post-transplant period, blood pressure was maintained above 110/70 mmHg by intermittent infusion of dopamine. Hypotension was improved after 24 days and dopamine was discontinued. Various etiologies may cause chronic hypotension in patients receiving long-term HD treatment. Kidney transplantation may improve survival and quality of life by correcting hypotension in these patients. Therefore kidney transplantation should not be avoided as renal replacement therapy in ESRD patients with hypotension.

    PurposeTo present our experience performing endovascular repair of abdominal aortic aneurysms in kidney transplanted patients.MethodsA retrospective review of all patients who underwent endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA) performed at our institution from 2007 to 2014. We identified all patients who had previously undergone a kidney transplant. Data collected included: comorbidities, preoperative imaging modalities, indication for surgery, stent graft configurations, pre- and postoperative renal function, perioperative complications, and survival rates.ResultsA total of 267 EVARs were performed. Six (2 %) had a transplanted kidney. Mean age was 74 (range, 64–82) years; five were males. Mean time from transplantation to EVAR was 7.5 (range, 2–12) years. Five underwent preoperative planning with noncontrast modalities only. Devices used included bifurcated (n = 3), aortouniiliac (n = 2), and tube (n = 1) stent grafts. Technical success was achieved in all patients. None experienced deterioration in renal function. Median follow-up was 39 (range, 6–51) months. Four patients were alive at the time of the study. Two patients expired during the period of follow-up from unrelated causes.ConclusionsEVAR is an effective modality for the management of AAAs in the coexistence of a transplanted kidney. It can be performed with minimal morbidity and mortality without harming the transplanted kidney. Special consideration should be given to device configuration to minimize damage to the renal graft.

    Kidney transplantation is considered a cost-effective treatment compared to dialysis but accounts for a significant percentage of the public health care resources. Therefore, efficient systems capable of performing high number of procedures are attractive and sustainable. The aim of this study was to evaluate clinical outcomes of 11,436 kidney transplants regularly performed in a single transplant dedicated center over the last 18 years. This was a retrospective study performed in a single specialized transplant center. All consecutive patients who underwent transplantation between 08/18/1998 and 12/31/2015 were included in the analysis. The annual number of transplants increased from 394 in 1999 to 886 in 2015, with a progressive reduction in the proportion of living donor kidney transplants (70% vs. 23%) and yielding over 8869 patients in regular follow up. Of 11,707 kidney transplants performed, 5348 (45.7%) were from living, 3614 (30.9%) standard and 1618 (13.8%) expanded criteria deceased donors, 856 (7.3%) pediatric and 271 (2.3%) simultaneous kidney-pancreas transplants. Comparing 1998-2002 and 2011-2014, five-years graft survival increased for kidney transplants performed with living donors (83.3% vs. 93.1%, p transplants, in the cumulative number of patients in follow up and a shift from living related to deceased donor kidney transplants, with associated progressive increase in patient and graft survivals. Transplante renal é considerado um tratamento custo-efetivo comparado à diálise e representa uma porcentagem significativa dos recursos de saúde pública.

    Kidney transplantation is considered to be the best treatment for people with chronic kidney failure, because it improves the patients' quality of life and increases their length of survival compared with patients undergoing dialysis. The kidney transplantation process in Brazil is defined through laws, decrees, ordinances, and resolutions, but there is no visual representation of this process. The aim of this study was to analyze official documents to construct a representation of the kidney transplantation process in Brazil with the use of business process modeling notation (BPMN). The methodology for this study was based on an exploratory observational study, document analysis, and construction of process diagrams with the use of BPMN. Two rounds of validations by specialists were conducted. The result includes the kidney transplantation process in Brazil representation with the use of BPMN. We analyzed 2 digital documents that resulted in 2 processes with 45 total of activities and events, 6 organizations involved, and 6 different stages of the process. The constructed representation makes it easier to understand the rules for the business of kidney transplantation and can be used by the health care professionals involved in the various activities within this process. Construction of a representation with language appropriate for the Brazilian lay public is underway. Copyright © 2015 Elsevier Inc. All rights reserved.

  4. Acute myeloid leukemia after kidney transplantation: a case report and literature review

    Francesca Cardarelli

    Full Text Available Abstract The incidence of malignancy is greater in kidney transplant recipients compared to the general population, though the higher risk is not equally distributed to all types of cancers. In face of the increased longevity of renal transplant recipients, certain cancers, such as acute leukemias, are becoming more prevalent. Acute myeloid leukemia (AML typically presents with cytopenias and infections, both common findings after kidney transplantation. Therefore, the diagnosis of AML may be initially overlooked in these patients. We report the case of a 33-year-old man who presented with fever, pancytopenia and acute worsening of his renal allograft function 9 years after a living unrelated kidney transplant. After initial negative infectious work-up, a kidney biopsy revealed C4d-positive antibody-mediated rejection in combination with scattered atypical inflammatory cells. A subsequent bone marrow biopsy confirmed AML. He underwent successful induction chemotherapy with daunorubucin and cytarabine and ultimately achieved a complete remission.

Herein, we discuss the prevalence, risk factors, presentation and management of leukemia after kidney transplantation.

    France transplant was founded in order to organize rationally the cadaver kidneys transport and transplantation with is omogenous compatibility tests. 2143 hemodialysis patients have been presently (1-9-72) treated in 82 dialysis center in France; 964 of them are in the France Transplant waiting list. According with recent laws, nervous function cessation is synonimous of death. That made possible, by good resuscitation techniques, to maintain a good level of circulation and oxigenation of organs. Family permit is required for this purpose. 17 medical transporttion staffs are at work in 12 France towns and cooperate with 12 typing laboratoires working with the same techniques and reagents. One permanent secretariat in Paris is always telex connected with all staffs and mantains a continuous up to date patients waiting list. 415 cadaver kidneys were transplanted, 255 in the same town and 160 trabsported from a town another. A significative rise in cold ischemia times happened recently because of the increasing number of transported kidneys.

    Full Text Available The objective of the study is to evaluate the relationship between serum testos-terone levels and cardiovascular risk factors (CVRF in patients after kidney transplantation and with chronic kidney disease (CKD. Seventy-five male patients, aged between 18 and 68 years, who had kidney transplantation at least six months earlier, were enrolled into the study. Only renal transplant recipients and CKD patients with a creatinine level of 0.05. Serum testosterone levels were independent risk factors affecting IVC collapse index, systolic BP and LA. m-TORi and CNIs drugs might have no negative effect on serum testosterone levels, and improvement of the serum testosterone levels after transplantation might have a positive contribution on cardiac risk factors.

    Background: Chronic kidney disease (CKD) is a worldwide public health problem with increasing incidence and prevalence and associated expenses. Objectives: To explore different perceptions of rural and urban patients with chronic kidney disease (CKD) about kidney transplant. Patients and Methods: We conducted four focus groups, each including 5 or 6 patients with stage 5 CKD or end stage renal disease living in a rural or urban area. Open-ended questions probed patient familiarity with kidney transplant, perceptions of benefits of kidney transplant, perceived barriers to kidney transplant, and views about living donation. All the sessions were recorded and professionally transcribed. Responses were pooled, de-identified, and analyzed using qualitative thematic content analysis. Results: Urban patients were more likely to receive supplementary information and being strongly encouraged by their nephrologists to seek transplant. All participants acknowledged “independence” as the main advantage of transplantation. Increased freedom to travel and improved life expectancy were mentioned only among the urban groups. The main themes in all groups regarding perceived barriers to transplant were the tedious pre-transplant testing and workup expenses. Among rural groups, there was a perception that distance from transplant centers impedes transplant evaluation. Religious reasons favoring and opposing transplant were mentioned by participants in a rural group. Some members contended that since illness is God’s will, we should not change it. Others in the same group argued that “God is not ready for us to give up”. Praise and gratitude for the living donor were expressed in all groups, but concerns about donor’s outcome were discussed only within the rural groups. In discussing preference about known or anonymous donors, members of an urban group mentioned favoring an anonymous donor, citing unease with a sense of life-long indebtedness. Conclusions: Observed

    Live-donor kidney transplantation (LDKT) is the best treatment for eligible people with late-stage kidney disease. Despite this, living kidney donation rates have declined in the United States in recent years. A potential source of this decline is the financial impact on potential and actual living kidney donors (LKDs). Recent evidence indicates that the economic climate may be associated with the decline in LDKT and that there are nontrivial financial ramifications for some LKDs. In June 2014, the American Society of Transplantation's Live Donor Community of Practice convened a Consensus Conference on Best Practices in Live Kidney Donation. The conference included transplant professionals, patients, and other key stakeholders (with the financial support of 10 other organizations) and sought to identify best practices, knowledge gaps, and opportunities pertaining to living kidney donation. This workgroup was tasked with exploring systemic and financial barriers to living kidney donation. The workgroup reviewed literature that assessed the financial effect of living kidney donation, analyzed employment and insurance factors, discussed international models for addressing direct and indirect costs faced by LKDs, and summarized current available resources. The workgroup developed the following series of recommendations to reduce financial and systemic barriers and achieve financial neutrality for LKDs: (1) allocate resources for standardized reimbursement of LKDs' lost wages and incidental costs; (2) pass legislation to offer employment and insurability protections to LKDs; (3) create an LKD financial toolkit to provide standardized, vetted education to donors and providers about options to maximize donor coverage and minimize financial effect within the current climate; and (4) promote further research to identify systemic barriers to living donation and LDKT to ensure the creation of mitigation strategies.

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

    Improving access to optimal healthcare may depend on the attributes of neighborhoods where patients receive healthcare services. We investigated whether the characteristics of dialysis facility neighborhoods--where most patients with end-stage renal disease are treated--were associated with facility-level kidney transplantation. We examined the association between census tract (neighborhood)-level sociodemographic factors and facility-level kidney transplantation rate in 3,983 U.S. dialysis facilities where kidney transplantation rates were high. Number of kidney transplants and total person-years contributed at the facility level in 2007-2010 were obtained from the Dialysis Facility Report and linked to the census tract data on sociodemographic characteristics from the American Community Survey 2006-2010 by dialysis facility location. We used multivariable Poisson models with generalized estimating equations to estimate the link between the neighborhood characteristics and transplant incidence. Dialysis facilities in the United States were located in neighborhoods with substantially greater proportions of black and poor residents, relative to the national average. Most facility neighborhood characteristics were associated with transplant, with incidence rate ratios (95% CI) for standardized increments (in percentage) of neighborhood exposures of: living in poverty, 0.88 (0.84-0.92), black race, 0.83 (0.78-0.89); high school graduates, 1.22 (1.17-1.26); and unemployed, 0.90 (0.85-0.95). Dialysis facility neighborhood characteristics may be modestly associated with facility rates of kidney transplantation. The success of dialysis facility interventions to improve access to kidney transplantation may partially depend on reducing neighborhood-level barriers. © 2014 S. Karger AG, Basel.

  12. Combined Bone Marrow and Kidney Transplantation for the Induction of Specific Tolerance

    Full Text Available The induction of specific tolerance, in order to avoid the detrimental effects of lifelong systemic immunosuppressive therapy after organ transplantation, has been considered the “Holy Grail” of transplantation. Experimentally, tolerance has been achieved through clonal deletion, through costimulatory blockade, through the induction or infusion of regulatory T-cells, and through the establishment of hematopoietic chimerism following donor bone marrow transplantation. The focus of this review is how tolerance has been achieved following combined bone marrow and kidney transplantation. Preclinical models of combined bone marrow and kidney transplantation have shown that tolerance can be achieved through either transient or sustained hematopoietic chimerism. Combined transplants for patients with multiple myeloma have shown that organ tolerance and prolonged disease remissions can be accomplished with such an approach. Similarly, multiple clinical strategies for achieving tolerance in patients without an underlying malignancy have been described, in the context of either transient or durable mixed chimerism or sustained full donor hematopoiesis. To expand the chimerism approach to deceased donor transplants, a delayed tolerance approach, which will involve organ transplantation with conventional immunosuppression followed months later by bone marrow transplantation, has been successful in a primate model. As combined bone marrow and organ transplantation become safer and increasingly successful, the achievement of specific tolerance may become more widely applicable.

    Full Text Available Çiğdem Akalın Akkök,1,21Department of Immunology and Transfusion Medicine, Oslo University Hospital, Ullevaal, Oslo, Norway; 2Department of Clinical Immunology and Transfusion Medicine, Lund University Hospital, Lund, Sweden Abstract: Allogeneic hematopoietic stem cell transplantation (AHSCT is an intention-to-cure treatment strategy in several malignancies and nonmalignancies. The number of patients receiving AHSCT is increasing due to new indications, and more elderly patients with comorbidities are included in the protocols. Survival of the patients undergoing AHSCT has improved owing to better patient care, including optimization of transfusion support, which has a major contribution. However, transfusion can also be hazardous. Increasing awareness about transfusion and finding the balance between avoiding unnecessary transfusions and transfusing the correct component when needed are the key issues. Myeloablative conditioning results in pancytopenia, and the patients are prone to infections, anemia, and bleeding both before and after transplantation. Until red cell and platelet engraftment, the patients are usually transfusion dependent needing red cell and/or platelet components. Physicians dealing with AHSCT patients should be well informed about the attributes of the blood components they order. Knowledge about transfusion indications, triggers, and how to prevent and manage eventual transfusion complications is also required. The clinical picture can be challenging, and transplantation/treatment-related toxicity/complications can sometimes be difficult to distinguish from a transfusion complication, especially if the latter one took place, for instance, several days or weeks ago. ABO compatibility between the patient and the donor is not a prerequisite when choosing human leukocyte antigen-matched hematopoietic stem cell donor. Consequently, ABO incompatibility exists in ~40% of the cases and brings some immunohematological issues

    Background: Chronic obstructive pulmonary disease (COPD) and tobacco use are leading causes of morbidity and mortality. The prevalence and clinical impact of COPD on mortality and kidney transplantation among patients who begin dialysis therapy is unclear. Methods: We explored the clinical impact of COPD and continued tobacco use on overall mortality and kidney transplantation in a national cohort study of US dialysis patients. National data on all dialysis patients (n = 769,984), incident between May 1995 and December 2004 and followed until October 31, 2006, were analyzed from the United States Renal Data System. Prevalence and period trends were determined while multivariable Cox regression evaluated relative hazard ratios (RR) for death and kidney transplantation. Results: The prevalence of COPD was 7.5% overall and increased from 6.7 to 8.1% from 1995-2004. COPD correlated significantly with older age, cardiovascular conditions, cancer, malnutrition, poor functional status, and tobacco use. Adjusted mortality risks were significantly higher for patients with COPD (RR = 1.20, 95% CI 1.18-1.21), especially among current smokers (RR = 1.28, 95% CI 1.25-1.32), and varied inversely with advancing age. In contrast, the adjusted risks of kidney transplantation were significantly lower for patients with COPD (RR = 0.47, 95% CI 0.41-0.54, for smokers and RR = 0.54, 95% CI 0.50-0.58, for non-smokers) than without COPD [RR = 0.72, 95% CI 0.70-0.75, for smokers and RR = 1.00 for non-smokers (referent category)]. Conclusions: Patients with COPD who begin dialysis therapy in the US experience higher mortality and lower rates of kidney transplantation, outcomes that are far worse among current smokers.

    Before the 2014 implementation of a new kidney allocation system by the United Network for Organ Sharing, white patients were more likely than black or Hispanic patients to receive a kidney transplant. To determine the effect of the new allocation system on these disparities, we examined data for 179,071 transplant waiting list events in the period June 2013-September 2016, and we calculated monthly transplantation rates (34,133 patients actually received transplants). Implementation of the new system was associated with a narrowing of the disparities in the average monthly transplantation rates by 0.29 percentage point for blacks compared to whites and by 0.24 percentage point for Hispanics compared to whites, which resulted in both disparities becoming nonsignificant after implementation of the new system.

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

    Due to the limited access to kidney transplantation (KTx) in developing countries, desperate patients have engaged in the purchase and sale of kidneys. In 2004, the World Health Assembly urged member states to protect the poor and vulnerable from being exploited through practices of illegal organ trafficking that had become widespread throughout the world. In 2008, the international transplant community convened a summit of transplant professionals, legal experts and ethicists to combat organ trafficking, transplant tourism and transplant commercialism that resulted in the Declaration of Istanbul (DOI). The South-Eastern Europe Health Network (SEEHN) represents a nine country multigovernmental collaboration on health systems. The Regional Health Development Centre on Organ Donation and Transplant Medicine (RHDC) was established in 2011 in Croatia to facilitate cooperation among south-eastern European countries to improve organ transplantation within the Balkan region. Since 2011, a collaboration between the RHDC, the Custodian Group of the DOI (DICG) and SEEHN professionals has enhanced strategic planning and definition of country-specific action plan priorities on organ donation and transplantation. Data of kidney transplantation provided in this report show a significant increase in transplantation activities in a 4-year period in Macedonia, Moldova, Bosnia and Hercegovina, Romania and Montenegro. The success of the donation and transplantation programmes was influenced by the engagement of key professionals and the establishment of organizational infrastructure with the implementation of an appropriate funding model. In conclusion, the DOI has provided an ethical framework for engagement of health professionals from south-eastern European countries. The newly established SEEHN RHDC as a technical coordinating body greatly contributed in building institutional capacity and strengthening regional collaboration between health authorities and professionals within
