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

    Renal transplantation is considered now the definitive treatment for patients with end-stage renal disease (ESRD). Unfortunately, the worldwide shortage of kidneys remains the most important obstacle to transplantation. In developing countries, including those of the Middle East, the shortage is even more dramatic. Despite great efforts to establish and maintain successful transplant centers, the number of kidneys that have been transplanted in the last few years has actually declined. The lack of a dependable kidney source played well into the hands of unscrupulous entrepreneurs who started brokerage of organs for profit. In this practice, patients with ESRD travel to India and other countries to purchase kidneys from living genetically non-related poor donors. Patient care was therefore relegated to the laws of the marketplace and both patients and donors were exploited to maximize profit. Additionally, reported results of this type of transplantation were inferior to those of other types of transplantation. Not unexpectedly, these issues have created intense controversy among transplant physicians and the general public in which moral, ethical and medical issues were debated. To investigate these issues, we conducted a large multicenter study in Saudi Arabia, Bahrain and Egypt. In the first phase of this study, we surveyed 50 institutions regarding their attitude toward LNRRT, of which 22 responded. The results of our survey clearly show that patients with ESRD take the initiative in seeking LNRRT despite physician discouragement and significant financial burden.(ABSTRACT TRUNCATED AT 250 WORDS)

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

    2014-01-01

    Background In Mexico, diabetes mellitus is the main cause of end − stage kidney disease, and some patients may be transplant candidates. Organ supply is limited because of cultural issues. And, there is a lack of standardized clinical guidelines regarding organ donation. These issues highlight the tension surrounding the fact that living donors are being selected despite being prediabetic. This article presents, examines and discusses using the principles of non-maleficience, autonomy, justice and the constitutionally guaranteed right to health, the ethical considerations that arise from considering a prediabetic person as a potential kidney donor. Discussion Diabetes is an absolute contraindication for donating a kidney. However, the transplant protocols most frequently used in Mexico do not consider prediabetes as exclusion criteria. In prediabetic persons there are well known metabolic alterations that may compromise the long − term outcomes of the transplant if such donors are accepted. Even so, many of them are finally included because there are not enough donor candidates. Both, families and hospitals face the need to rapidly accept prediabetic donors before the clinical conditions of the recipient and the evolution of the disease exclude him/her as a transplant candidate; however, when using a kidney potentially damaged by prediabetes, neither the donor’s nor the recipient’s long term health is usually considered. Considering the ethical implication as well as the clinical and epidemiological evidence, we conclude that prediabetic persons are not suitable candidates for kidney donation. This recommendation should be taken into consideration by Mexican health institutions who should rewrite their transplant protocols. Summary We argue that the decision to use a kidney from a living donor known to be pre-diabetic or from those persons with family history of T2DM, obesity, hypertension, or renal failure, should be considered unethical in Mexico

    We successfully made ABO-incompatible renal transplantation, of which report is methodologically the first in Japan and probably the second in the world to our knowledge. Sixty year-old-female (mother) with B-blood type donated her right kidney to 36 years-old male (son) with O-blood type. Pretransplant removal of plasma isoagglutinin of the recipient through plasma exchange with albumin solution followed by hemodialysis with administration of fresh frozen B-type plasma effectively reduced the anti-BIgM-antibody titre of x256 to x8 and the anti-IgG-antibody titre of x512 to x16. Splenectomy was performed at the time of transplantation. On the 10th POD, the anti-B antibody titres were more decreased to IgM antibody x2 and IgG antibody x8. Patient is doing well without any sign of rejection as of 4 months postoperatively.

    Background Relationship between live donor renal anatomic asymmetry and post-transplant recipient function has not been studied extensively. Methods We analyzed 96 live-kidney donors, who had anatomical asymmetry (>10% renal length and/or volume difference calculated from CT angiograms) and their matching recipients. Split function differences (SFD) were quantified with 99mTc-DMSA renography. Implantation biopsies at time-zero were semi-quantitatively scored. A comprehensive model utilizing donor renal volume adjusted to recipient weight (Vol/Wgt), SFD, and biopsy score was used to predict recipient estimated glomerular filtration rate (eGFR) at one-year. Primary analysis consisted of a logistic regression model of outcome (odds of developing eGFR>60ml/min/1.73 m2 at one-year), a linear regression model of outcome (predicting recipient eGFR at one-year, using the CKD-EPI formula), and a Monte Carlo simulation based on the linear regression model (N=10,000 iterations). Results In the study cohort, the mean Vol/Wgt and eGFR at one-year were 2.04 ml/kg and 60.4 ml/min/1.73m2, respectively. Volume and split ratios between two donor kidneys were strongly correlated (r=0.79, p-value<0.001). The biopsy scores among SFD categories (<5%, 5–10%, >10%) were not different (p=0.190). On multivariate models, only Vol/Wgt was significantly associated with higher odds of having eGFR>60ml/min/1.73 m2 (OR=8.94, 95% CI 2.47–32.25, p=0.001) and had a strong discriminatory power in predicting the risk of eGFR<60ml/min/1.73m2 at one-year (ROC curve=0.78, 95% CI 0.68–0.89). Conclusion In the presence of donor renal anatomic asymmetry, Vol/Wgt appears to be a major determinant of recipient renal function at one-year post-transplantation. Renography can be replaced with CT volume calculation in estimating split renal function. PMID:25719258

    Introduction and Objective: Among the surgical complications in renal transplantation, the vascular complications are probably most dreaded, dramatic, and likely to cause sudden loss of renal allograft. We present our experience and analysis of the outcome of such complications in a series of 1945 live related renal transplants. Materials and Methods: One thousand nine hundred and forty five consecutive live related renal transplants were evaluated retrospectively for vascular complications. Complications were recorded and analyzed for frequency, time of presentation, clinical presentation, and their management. Results: The age of patients ranged from 6 to 56 years (mean = 42). Vascular complications were found in 25 patients (1.29%). Most common among these was transplant renal artery stenosis found in 11 (0.58%), followed by transplant reznal artery thrombosis in 9 (0.46%), renal vein thrombosis in 3 (0.15%), and aneurysm formation at arterial anastmosis in 2 (0.10%) patient. The time of presentation also varied amongst complications. All cases of arterial thrombosis had sudden onset anuria with minimal or no abdominal discomfort, while venous thrombosis presented as severe oliguria associated with intense graft site pain and tenderness. Management of cases with vascular thrombosis was done by immediate surgical exploration. Two patients of renal artery stenosis were managed with angioplasty and stent placement. Conclusions: Major vascular complications are relatively uncommon after renal transplantation but still constitute an important cause of graft loss in early postoperative period. Aneurysm and vessel thrombosis usually require graft nephrectomy. Transplant renal artery stenosis is amenable to correction by endovascular techniques. PMID:23671364

    Renal cell carcinoma can occur in children who have received renal allografts from adults. Chromophobe renal cell carcinoma is a rare variant of renal carcinoma with distinct histochemical, ultrastructural, and genetic characteristics. We describe the incidental finding of a chromophobe renal cell carcinoma in a 13 1/2-year-old boy 5 years after receiving a living-related renal transplant. This tumor was found by serendipity during the evaluation of fever and inguinal lymphadenopathy, with the presumptive diagnosis of posttransplantation lymphoproliferative disorder. The patient was found to have cat-scratch disease. A renal cell carcinoma should be considered in the differential diagnosis of a pediatric recipient of an adult kidney with an incidental finding of a tumor in the graft.

    Background: Chronic allograft nephropathy (CAN) is a common cause of delayed allograft failure throughout the world. Its prevalence and risk factors vary depending on a number of factors. There is little information on the prevalence and risk factors for early CAN in live related renal transplant patients. Objectives: We aimed to determine the prevalence and the risk factors of early CAN in our setup. Patients and Methods: The study was conducted at Sindh Institute of Urology & Transplantation (SIUT), Karachi, from 2002 to 2005 on patients who had live related kidney transplantation and underwent at least one allograft biopsy within 18 months of transplantation. The biopsies were performed and prepared in accordance with established indications and guidelines. The Banff 97 classification and its updates were used to diagnose and categorize the biopsy pathology. Patients were divided into two groups depending on the presence or absence of CAN on biopsies. Following parameters were compared among the groups: age, sex, human leukocyte antigen (HLA) match, immunosuppression used, acute rejection (AR) episodes, urinary tract infections (UTIs), viral infections, cyclosporine levels, early and late graft function monitored by serum creatinine. Results: A total of 164 patients fulfilled the study inclusion criteria. The mean age of recipients and donors was relatively young. The majority of the donors were siblings. The overall prevalence of CAN was 25.6% (42/164), between 3 and 18 months post transplantation. The median time to the appearance of CAN was 9 months post-transplant. The prevalence of CAN increased as post-transplant duration increased. In 39 (92.8%) subjects, CAN was detected on the second or subsequent graft biopsy. Only 3 (7.2%) patients showed CAN on the first graft biopsy. The majority of cases belonged to moderate degree or grade II CAN. The mean serum creatinine values were higher in the CAN group at the time of discharge and all times post-transplantation

    Thirty-one children received 38 kidney transplants from 22 live and 16 cadaver donors. Among the 31 patients, 25 received one transplant each, 5 received two transplants each and 1 received three transplants. Peritoneal or hemodialysis (or both) was carried out in 22 patients, with an average dialytic maintenance of 12 weeks before transplantation. Posttransplant immunosuppressive therapy included prednisone and azathioprine. Antilymphocyte globulin was administered to 33 recipients as adjunctive immunosuppressive therapy. At present, 23 patients have functioning allografts, 3 are on hemodialysis and 5 are dead. Of 22 live kidney transplants, 18 are presently functioning two months to 14 years after transplantation with an average of 36 months. Of 16 cadaver kidney transplants, 5 are presently functioning 9 to 57 months after transplantation with an average of 32 months. Actuarial live donor allograft survival for one year was 76 percent, for two years was 66 percent and for three years was 64 percent. Cadaver allograft survival was 50 percent, 40 percent and 40 percent, respectively. Complications were urologic and infection related. Of nine recipients with sustained hypertension, in six the condition was due to chronic rejection, while in one it was due to recurrence of the original disease in the allograft. Linear growth was measured in 15 children who were less than 14 years of age at the time of transplantation and in whom allografts survived more than one year. Maximum average linear growth velocity occurred during the first year after transplantation. Our experience indicates pediatric renal transplantation can be successfully used in the treatment of terminal renal failure. PMID:1098288

    The number of pediatric patients with end stage renal disease (ESRD) has been steadily growing during the last 10 years all over the world, because of the improvement of medical and surgical treatment of severe urologic malformations and congenital and acquired nephrological disorders. Kidney transplantation (Tx) with a live related donor continues to be the gold standard therapy to treat ESRD in children because of the best final results, the chronic lack of cadaveric donors and the frequent possibility of young patients to have parents or relatives as a source of a potential graft donor. Nowadays almost every pediatric patient can be dialyzed and transplanted, even early in life, if he or she has the possibility of a live related donor. Improvements in pediatric anesthesiology and intensive care have also been very important, in reducing the morbidity and mortality related to Tx procedures. Here we report our experience with Tx for the last 25 years, specially our long experience of live related donor transplantation in children and adolescents with emphasis on technical issues in small children and pediatric patients with severe urologic malformations and bladder dysfunction. We'll make special considerations on the improvement in short and long follow-up with the actual prevention and treatment of graft rejection, due to the new immunosuppressive agents and protocols.

    Between May 1998 and June 2006, 31 patients (21 males and 10 females) received a renal allograft from live-related donors at the Urology and Nephrology Center in the Al-Thawra Modern General Hospital Sana'a, Republic of Yemen. The cold ischemia time ranged between 48 and 68 minutes. The immunosuppressive protocol was double therapy (steroids and mycophenolate) in the first 8 cases. The subsequent cases received triple therapy with steroids, cyclosporine and mycophenolate. Episodes of acute rejection were treated with high dose steroids while anti-thymocyte globulin (ATG) was also used in cases of vascular or steroid resistant rejection. Primary graft function was achieved in 29 recipients (93.5%). The post-transplant complications, either surgical or medical, were comparable to those reported in the literature. The kidney transplantation program started sporadically in Yemen since 1998. However, a well-established program has been running regularly since the beginning of 2005.

    Ischemic conditioning involves the delivery of short cycles of reversible ischemic injury in order to induce protection against subsequent more prolonged ischemia. This randomized controlled trial was designed to determine the safety and efficacy of remote ischemic conditioning (RC) in live donor kidney transplantation.This prospective randomized clinical trial, 80 patients undergoing live donor kidney transplantation were randomly assigned in a 1:1 ratio to either RC or to a control group. RC consisted of cycles of lower limb ischemia induced by an arterial tourniquet cuff placed around the patient's thigh. In the RC treatment group, the cuff was inflated to 200 mm Hg or systolic pressure +25 mm Hg for 4 cycles of 5 min ischemia followed by 5 min reperfusion. In the control group, the blood pressure cuff was inflated to 25 mm Hg. Patients and medical staff were blinded to treatment allocation. The primary end-point was renal function measured by estimated glomerular filtration rate (eGFR) at 1 and 3 months posttransplant.Donor and recipient demographics were similar in both groups (P < 0.05). There were no significant differences in eGFR at 1 month (control 52 ± 14 vs RC 54 ± 17 mL/min; P = 0.686) or 3 months (control 50 ± 14 vs RC 49 ± 18 mL/min; P = 0.678) between the control and RC treatment groups. The RC technique did not cause any serious adverse effects.RC, using the protocol described here, did not improve renal function after live donor kidney transplantation.

    Background Because simultaneous liver and kidney transplantation has been limited as a standard practice because of a severe shortage of deceased donors in Japan, living donor (LD) liver transplantation alone (LTA) is indicated in most recipients with maintenance renal replacement therapy (MRRT). Methods A retrospective nationwide survey of LD LTA was performed for liver transplant patients on MRRT. The characteristics of donors and recipients, postoperative complications, survival rate, and causes of death were analyzed. Results In the adult cases (n = 28), the overall survival rate at 1 year and 5 years were 66.1% and 57.3%, respectively. When compared with those adults without MRRT (n = 237), it was significantly worse. In the 7 pediatric cases, the overall survival rate at 1 and 5 years were both 83.3%. Three adult recipients died of nonaneurysm cerebral hemorrhage after 1 year and 1 adult recipient died of acute heart failure after 7 months. In adult recipients with MRRT, graft weight versus standard liver volume, and duration and blood loss in LTA surgery were associated with poor outcomes after LD LTA. Multivariate analysis revealed that MRRT was highest hazard ratio on patient survival after LD LTA. Conclusions Early post-LD LTA mortality was higher in patients with MRRT than in those without MRRT with characteristic causes. Smaller grafts for size and a complicated surgery were associated with poor outcome after LD LTA. Thus, LD LTA in adult patients on MRRT should be carefully treated with meticulous postoperative management and follow-up. PMID:27500264

    Renal transplantation from living donor parents was performed in two brothers with end-stage renal failure due to Alport syndrome (AS). Two years later, the patient receiving the kidney graft from the mother, obligate carrier of AS, presented persistent microhematuria and proteinuria with normal renal function. The histological study demonstrated ultrastructural glomerular lesions consistent with AS. The authors conclude that: (1) Alport patients should not be deprived of renal transplantation from living donors, since anti-GBM nephritis is a rare complication; (2) an oligosymptomatic female carrier of the Alport gene may be considered as living renal donor, although a longer follow-up is needed in order to draw definitive conclusions.

    The timing of renal transplantation in infants is controversial. Between 1965 and 1989, 79 transplants in 75 infants less than 2 years old were performed: 23 who were 12 months or younger, 52 who were older than 12 months; 63 donors were living related, 1 was living unrelated, and 15 were cadaver donors; 75 were primary transplants and 4 were retransplants. Infants were considered for transplantation when they were on, or about to begin, dialysis. All had intra-abdominal transplants with arterial anastomosis to the distal aorta. Sixty-four per cent are alive with functioning grafts. The most frequent etiologies of renal failure were hypoplasia (32%) and obstructive uropathy (20%); oxalosis was the etiology in 11%. Since 1983 patient survival has been 95% and 91% at 1 and 5 years; graft survival has been 86% and 73% at 1 and 5 years. For cyclosporine immunosuppressed patients, patient survival is 100% at 1 and 5 years; graft survival is 96% and 82% at 1 and 5 years. There was no difference in outcome between infants who were 12 months or younger versus those who were aged 12 to 24 months; similarly there was no difference between infants and older children. Sixteen (21%) patients died: 5 after operation from coagulopathy (1) and infection (4); and 11 late from postsplenectomy sepsis (4), recurrent oxalosis (3), infection (2), and other causes (2). Routine splenectomy is no longer done. There has not been a death from infection in patients transplanted since 1983. Rejection was the most common cause of graft loss (in 15 patients); other causes included death (with function) (7), recurrent oxalosis (3), and technical complications (3). Overall 52% of patients have not had a rejection episode; mean creatinine level in patients with functioning grafts is 0.8 +/- 0.2 mg/dL. Common postoperative problems include fever, atelectasis, and ileus. At the time of their transplants, the infants were small for age; but with a successful transplant, their growth, head

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

    The purpose of review was increasing number of opportunistic infections with use of newer immunosuppression and difficulty in diagnosis and management of such patients. For this review, MEDLINE database was searched from 2000 to 2006 with the keywords of opportunistic infections in renal transplantation. Opportunistic infection is a serious clinical complication in patients receiving immunosuppressive therapy after kidney transplantation. The two major factors for successful renal transplantation are better control of rejection and better prevention and treatment of infection. In renal allograft recipient, immunosuppressive drug therapy is the major cause of immunocompromised status and occurrence of infections, which arise most commonly as a result of invasion by endogenous opportunists. The opportunistic infections with varicella zoster viruses, parvovirus B-19, polyomavirus, nocardia and mucormycosis in immunosuppressed patients were present with severe complications that are reviewed in this article. As a result of use of strong immunosuppressive drugs like tacrolimus, mycophenolate mofetyl and antirejection therapy with antithymocyte globulins, these infections are now seen frequently, so they should always be included in differential diagnostic consideration. New diagnostic procedures and new treatment strategies are required to allow early detection and successful treatment of opportunistic infections in kidney transplant recipients. PMID:19672339

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

    Since initiation of model for end-stage liver disease (MELD)-based allocation for liver transplantation, the risk of posttransplant end-stage renal disease (ESRD) has increased. Recent US data have demonstrated comparable, if not superior survival, among recipients of living donor liver transplants (LDLT) when compared to deceased donor liver transplant (DDLT) recipients. However, little is known about the incidence of ESRD post-LDLT. We analyzed linked Scientific Registry of Transplant Recipients (SRTR) and US Renal Data System (USRDS) data of first-time liver-alone transplant recipients from February 27, 2002 to March 1, 2011, and restricted the cohort to recipients with a laboratory MELD score ≤25 not on dialysis prior to transplantation, in order to evaluate the incidence of ESRD post-LDLT, and to compare the incidence among LDLT versus DDLT recipients. There were 28 707 DDLT and 1917 LDLT recipients included in the analyses. The 1-, 3- and 5-year unadjusted risk of ESRD was 1.7%, 2.9% and 3.4% in LDLT recipients, compared with 1.5%, 3.0% and 4.8% in DDLT recipients (p > 0.05), respectively. In multivariable competing risk Cox regression models, there was no association between receiving an LDLT and risk of ESRD (sub-hazard ratio: 0.99, 95% CI: 0.77-1.26, p = 0.92). In conclusion, the incidence of ESRD post-LDLT in the United States is low, and there are no significant differences among LDLT and DDLT recipients with MELD scores ≤25 at transplantation.

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

  4. A randomized study of intravenous fluid replacement following living-donor renal transplantation.

    Fourteen adult recipients of living-donor kidneys preserved with ice-cold intracellular electrolyte solution were randomly assigned to receive either high fluid replacement (total volume of urine output + 30 ml/hr) or low fluid replacement (constant 125 ml/hr) during the first 48 hr after grafting. High replacement recipients had significantly higher fluid intake and urine output than did low replacement recipients. However, net fluid balance at the end of the 48-hr study period was positive for both groups and not significantly different. Fractional excretion of sodium was directly related to urine output in all patients. Serum osmolality, serum sodium concentration, and urine sodium concentration were not significantly different in the treatment groups. Urine osmolality was significantly higher in the low-replacement group at 24 and 36 hr after transplantation. The i.v. replacement of total urinary output is unnecessary in adult recipients of living-donor kidneys preserved with ice-cold intracellular electrolyte solution because such grafts can conserve sodium and water immediately after transplantation.

    Historically HIV positive patients were considered a contraindication for renal transplant. After the year 1996, with the introduction of HAART the retropositive patients live longer and therefore end stage organ disease is now an increasingly important cause of mortality and morbidity in these patients. Here we report our experience for the first time in India. A forty nine year old hypertensive female from Africa who was diagnosed chronic kidney disease and retropositive status, progressed to end stage renal disease and underwent live related renal transplant at our centre.

    Renal transplant recipients carry a relatively high risk of developing tuberculosis (TB). In most cases, active TB is the result of reactivation of a latent infection and is located in the lungs. In these patients, clinical presentation of TB can often be atypical and there is a high risk of dissemination and high mortality rates. Therefore, the use of invasive procedures for proper diagnosis is recommended, as well as anti-tuberculosis therapy instituted whenever there is a strong suspicion of TB on clinical grounds, even without microbiological evidence. The treatment of active TB in renal transplant recipients should be the same as in the general population. To avoid graft rejection, blood levels of calcineurin inhibitors should be monitored closely. Prophylaxis is recommended for high-risk patients.

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

    In 1243 patients after renal transplantation, 39 malignant tumours were detected in 37 patients. The average latency period between transplantation and tumour disease was 72 months. Tumours included 8 malignant lymphomas, 7 dermatomas and 24 visceral tumours. The patients who developed a tumour had received fewer blood transfusions before transplantation than a tumour-free control group of 60 patients with renal transplants. Rejection crises occurred in a significantly smaller number of tumour patients compared with the control group.

    Renal transplantation has become one of the most common surgical procedures performed to replace a diseased kidney with a healthy kidney from a donor. It can help patients with kidney failure live decades longer. However, renal transplantation also faces a risk of developing various blood disorders. The blood disorders typically associated with renal transplantation can be divided into two main categories: (1) Common disorders including post-transplant anemia (PTA), post-transplant lymphoproliferative disorder (PTLD), post-transplant erythrocytosis (PTE), and post-transplant cytopenias (PTC, leukopenia/neutropenia, thrombocytopenia, and pancytopenia); and (2) Uncommon but serious disorders including hemophagocytic syndrome (HPS), thrombotic microangiopathy (TMA), therapy-related myelodysplasia (t-MDS), and therapy-related acute myeloid leukemia (t-AML). Although many etiological factors involve the development of post-transplant blood disorders, immunosuppressive agents, and viral infections could be the two major contributors to most blood disorders and cause hematological abnormalities and immunodeficiency by suppressing hematopoietic function of bone marrow. Hematological abnormalities and immunodeficiency will result in severe clinical outcomes in renal transplant recipients. Understanding how blood disorders develop will help cure these life-threatening complications. A potential therapeutic strategy against post-transplant blood disorders should focus on tapering immunosuppression or replacing myelotoxic immunosuppressive drugs with lower toxic alternatives, recognizing and treating promptly the etiological virus, bacteria, or protozoan, restoring both hematopoietic function of bone marrow and normal blood counts, and improving kidney graft survival.

    Transplantation is the optimal renal replacement therapy for children with end-stage renal disease. Compared with dialysis, successful transplantation in children and adolescents not only ameliorates uremic symptoms but also allows for significant improvement of delayed growth, sexual maturation, and psychosocial functioning. The child with a well-functioning kidney can enjoy a quality of life that cannot be achieved with dialysis therapy. The 5- and 10-year patient/graft survival rate in transplant recipients are 97.9/88.8% and 96.2%/79.4% based on Japanese Renal Transplant Registry Society data. This article reviews recent reports of pediatric renal transplantation including ABO-incompatible and preemptive renal transplantation in Japan.

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

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

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

    Renal transplantation offers patients with end-stage renal disease the best opportunity for rehabilitation and long-term survival. However, there is a critical shortage of transplantable kidneys worldwide. This plays well into the hands of transplanters and entrepreneurs involved in commercial renal transplantation, particularly in India. This practice has been condemned by all transplant societies. In our fight against rampant commercialism in renal transplantation, we sought to describe feelings of patients who had received transplants in India, and the difficulties they faced during their stay there. The results show that the two reasons that motivated patients to go to India were lack of living-related donors and the need for prompt transplant. More than half of the patients did not meet their donors. Their experience, however, has been largely positive except for some negative feelings toward the broker and the standard of hospital hygiene. The total cost of the transplant was far less than that in the West but, despite that, some patients felt financially exploited. Communication with them was poor, as most patients did not get adequate pretransplant education and were not informed of possible complications including rejection and graft loss. Furthermore, almost half of the patients were not given medical reports. These results substantiate the impression that CRT in India does not conform to the high standards of renal transplant medicine.

    Here we have described a successful HLA-identical living allogeneic kidney transplantation after bone marrow transplantation in a patient with end-stag liver disease caused by multiple myeloma (MM). Our case is unique, because this combined transplantation is rarely possible and because of our unique immunosuppressive and management strategies. A 45-year-old man with ESRD MM and κ light-chain nephropathy was diagnosed. Cytostatic treatment resulted in partial remission, so autologous peripheral stem cell transplantation (SCT) was performed leading to a complete remission; however the patient remained anuric. The patient's HLA-identical brother offered to be a donor of peripheral stem cells for collection and cryopreservation. Kidney transplantation was performed with a combination of tacrolimus sirolimuns, and methylprednisolone. With a well-functioning kidney graft, allogeneic SCT was performed in the incipient relapse phase of MM, after total body irradiation. Severe oropharyngeal infections, diarrhea, sepsis, and renal failure. Fearing acute renal rejection, we administered steroid bolus. He experienced therapy with gradual restoration of kidney function. Then, steroid-responsive acute graft-versus-host disease (grade II, predominantly bowel) was diagnosed on the background of diarrhea, which returned once. Later he experienced a left subclavian vein thrombosis at the site of a central venous catheter and sepsis. Having recovered from these events, the patient enjoys good health, with stable kidney function and normal protein excretion. After the steroid was stopped, a bone marrow biopsy revealed full-donor type normocellular hemopoiesis. Because of the chimerism, we gradually discontinued the immunosuppression including, sirolimus and finally tacrolimus, since with minimal trough levels there were no complications. Bone marrow biopsy showed a complete remission. In MM with ESRD HLA-identical combined kidney and bone marrow transplantation from a living donor

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

    The economic indicators of Pakistan show that the GNP is dollar 70 billion and foreign exchange reserves stand at dollar 8.0 billion and foreign debt at more than dollar 36 billion. Against this backdrop, the government is unlikely to provide state-of-the-art facilities for management of end-stage organ failure. The unequal distribution of wealth leaves more than 40% below the poverty line. Economic solutions are based on temporary fixes where foreign aid and loans keeps the government machinery operational. Many of the basic health measures such as immunization are also foreign funded. Under such a scenario, local philanthropy has come to play a vital role. SIUT developed a model based on self-help--a model based on a community-government partnership, where the doctor plays the pivotal role and the beneficiary is the patient. SIUT acquired funds by developing a community-government partnership. The government fulfills about 40% of the total budget and the rest comes from the community as donations. The scheme has been extremely successful in providing free medical care and renal support to thousands of patients. It has been sustained over the past 15 years through complete transparency, public audit and accountability. These confidence-building means stimulate the community to come forward and donate money, equipment and medicines. The goal of transplantation is to provide organs to all with long-term survival of the graft. The emerging challenges to achieve this goal and efforts that can be made to increase and sustain transplant activity in Pakistan require a concerted effort on the part of the government, society and the medical profession.

    Antiphospholipid syndrome (APS) may occur in isolation or in association with systemic lupus erythematosus (SLE), with the potential to cause renal failure via several distinct pathologies. Renal transplantation in the presence of APS carries a risk of early graft loss from arterial or venous thrombosis, or thrombotic microangiopathy (TMA). Whilst perioperative anticoagulation reduces the risk of large vessel thrombosis, it may result in significant haemorrhage, and its efficacy in preventing post-transplant TMA is uncertain. Here, we report a patient with end-stage kidney disease (ESKD) due to lupus nephritis and APS, in whom allograft TMA developed soon after transplantation despite partial anticoagulation. TMA resolved with plasma exchange-based therapy albeit with some irreversible graft damage and renal impairment. We discuss the differential diagnosis of post-transplant TMA, and current treatment options.

    Background We aimed to longitudinally analyse changes in the levels of serum fibroblast growth factor 23 (FGF23), intact parathyroid hormone (iPTH) and associated minerals in patients undergoing renal transplantation. Methods Sixty-three patients with end-stage renal disease (ESRD) who underwent living donor transplantation were recruited. Serum FGF23, iPTH, uric acid, inorganic phosphorous (iP), blood urea nitrogen and serum creatinine were measured pre-transplant and at 1 (M1), 3 (M3) and 12 months (M12) post-transplantation. Results FGF23 levels were decreased at M1, M3 and M12 by 93.81, 96.74 and 97.53%, respectively. iPTH levels were decreased by 67.95, 74.95 and 84.9%, respectively. The prevalence of hyperparathyroidism at M1, M3 and M12 post-transplantation was 63.5, 42.9 and 11.1%, respectively. FGF23 and iP levels remained above the normal range in 23 (36.5%) and 17 (27%) patients at M1, 10 (15.9%) and 5 (8%) at M3 and in none at M12 post-transplantation, respectively. A multivariate regression model revealed that, pre-transplant, iP was positively associated with iPTH (P = 0.016) but not with FGF 23; however, post-transplant, iP level was negatively associated with FGF23 (P < 0.001) but not with iPTH. Conclusions Post-transplant FGF23 levels settle faster than those of iPTH. However, 11% of patients continued to have hyperparathyroidism even after 12 months. PMID:27679713

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

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

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

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

    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.

    8 cases of membranous glomerulonephritis (MG) after renal transplants (RT) are presented; one being a recurrence of the original disease and the other 7 due to a different cause of renal insufficiency. The total incidence of MG after transplantation was 1.63%; 1.39% being the incidence of MG of new cases. Only 1 patient showed decrease of renal function and in this case the MG was accompanied by chronic rejection lesions. There was no sign of neoplasias nor drugs producing MG. As far as chronic infections are concerned, only one patient showed B antigen and it was not observed during the immunofluorescent test in the biopsy. 6 patients had urological complications after the renal transplant (3 cases of urinary fistula; 2 cases of obstructive uropathy; 1 case of short ureter). 2 patients experienced the start of hemodialysis due to focal and segmentary glomerulosclerosis. The beginning of proteinuria commences between 2 and 23 months after the RT (median 13,0 +/- 7,5 moths); with a range of between 2.0 and 12.0 gr/day (median: 6.8 +/- 3,2 Z gr/day), this being nephrotic in 4 cases. Proteinuria improved 1 case, and persisted in the other patients at the same level registered previous to the diagnosis. MG is a non-frequent complication or RT and is usually benign. Patients with post-transplant urologic complications could be considered to have a higher risk of developing a MG "de novo".

    SUMMARY This report pertains to the psychiatric problems in renal transplant recipients and its socio-demographic correlations. 50 male recipient subjects with a post-transplant period ranging from six months to six years were evaluated through tape recorded interviews to study their pre and post-operative emotional reactions. A psychiatric examination was performed by two psychiatrists and a diagnosis given wherever necessary. On examination 46% of cases had identifiable psychiatric problems, mainly Anxiety Neurosis (18%), Depressive Neurosis (18%), Adjustment Reactions (10%). Non-organic (Psychogenic) pain, excessive somatic concern and personality changes were also noticed in some. The psychiatric illness was significantly more amongst unmarried (P < .05) and higher education group (P < .02). Other variables had no significant correlation with the psychiatric illness. None had psychoses or a major depressive disorder. Thus, psychiatric problems are present in particular groups of transplant recipients and are usually neurotic in nature and would require psychiatric help regarding these. PMID:21927072

    In India, patients without a compatible blood group donor are usually excluded from renal transplantation. For young patients, it is a difficult therapeutic choice to stay on long-term dialysis. We describe the case of a 19-year-old male patient who had blood group O +ve and had no compatible donor in the family. His mother was B +ve and was willing to donate. The patient had an initial anti-B antibody titer of 1:512 and underwent antibody depletion with plasmapheresis (11 sessions) and intravenous immunoglobulin (IVIG) 100 mg/kg after every plasmapheresis. He also received rituximab 500 mg for 3 days prior to transplant and was induced with basiliximab. At the time of transplant, his anti-B titers were <1:8. Post-operatively, he required four sessions of plasmapheresis and IVIG as his titers rebounded to 1:64. The titers then spontaneously subsided to <1:16 and have stayed at the same level for 6 months post-transplant. The patient continues to have normal renal function with a creatinine of 1.4 mg/dl% and has had no episodes of rejection. PMID:23814422

  10. Bone remodeling after renal transplantation.

    Several studies have indicated that bone alterations after transplantation are heterogeneous. Short-term studies after transplantation have shown that many patients exhibit a pattern consistent with adynamic bone disease. In contrast, patients with long-term renal transplantation show a more heterogeneous picture. Thus, while adynamic bone disease has also been described in these patients, most studies show decreased bone formation and prolonged mineralization lag-time faced with persisting bone resorption, and even clear evidence of generalized or focal osteomalacia in many patients. Thus, the main alterations in bone remodeling are a decrease in bone formation and mineralization up against persistent bone resorption, suggesting defective osteoblast function, decreased osteoblastogenesis, or increased osteoblast death rates. Indeed, recent studies from our laboratory have demonstrated that there is an early decrease in osteoblast number and surfaces, as well as in reduced bone formation rate and delayed mineralization after transplantation. These alterations are associated with an early increase in osteoblast apoptosis that correlates with low levels of serum phosphorus. These changes were more frequently observed in patients with low turnover bone disease. In contrast, PTH seemed to preserve osteoblast survival. The mechanisms of hypophosphatemia in these patients appear to be independent of PTH, suggesting that other phosphaturic factors may play a role. However, further studies are needed to determine the nature of a phosphaturic factor and its relationship to the alterations of bone remodeling after transplantation.

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

    Abstract One of the principal roles of a nephrologist is to closely monitor renal transplant allograft function and promptly evaluate any dysfunction. Renal transplant sonography has a major role in this assessment process given its ability to easily define renal transplant anatomy and surrounding structures. Abnormalities can be extrarenal or involve vascular, parenchymal and urological components of the graft and these can acutely or chronically influence graft function and survival. Procedural guidance as is required during allograft biopsy, as well as routine surveillance and screening for post transplant complications such as malignancy are also important applications of ultrasound in the management of renal transplant recipients. This article outlines key ultrasound findings and applications in renal transplantation from the clinician's perspective. PMID:28191257

  13. Afghan refugees in Iran model renal transplantation program: ethical considerations.

    During 23 years of civil war in Afghanistan, there has been a continuous flow of more than 5 million refugees out of the country. Iran has hosted about 40% of all refugees. The majority have resided outside of camps with opportunities to integrate locally, having access to the Iranian labor market and government services, such as dialysis and transplantation. Iran also has adopted a compensated living unrelated donor renal transplantation program in which foreigners can receive transplants from living related donors or volunteer living unrelated donors of the same nationality. In June 2004, among 241 refugees with end-stage kidney disease in Iran, 179 were on hemodialysis and 62 underwent renal transplantation. Nine patients received kidneys from living related donors, 1 from a spouse, 50 from Afghani living unrelated donors, and 1 from a cadaveric donor. No refugee had been used as a kidney donor to an Iranian patient. Transplantation of all Afghan refugees in need and the absence of their use as kidney donors to Iranian patients proffer strong evidence against commercialism and a reason to believe that the Iran Model transplantation is practiced with ethical standards. In the last 2 years since the civil war has ended, returning these patients to Afghanistan has raised important ethical concerns. Repatriation of dialysis patients and transplant recipients may be tantamount to their deaths. It is expected that The Transplantation Society and the World Health Organization will establish links with the United Nations High Commissioner for Refugee Offices to provide humanitarian assistance to these patients.

    Neurocognitive dysfunction is one of the major complications of chronic renal failure (CRF). Uremic state during CRF encompasses a wide spectrum of neurobehavioral and neurological disturbances. Recent studies showed that the pathophysiology of neurocognitive dysfunction in CRF is related to plasma levels of uremic solutes. Successful renal transplantation improves renal, metabolic, and endocrine functions and the quality of life. The aim of our study was to determine the state of neurocognitive function in pediatric renal transplant recipients. We prospectively performed a neurological examination and neuropsychological test battery (Bender-Gestalt Test, Cancellation Test, and Visual and Auditory Number Assay Test) in 20 pediatric renal transplant recipients between 6 and 16 years of age. Twenty healthy children and 20 children with CRF were included in the study as the control groups. Mean age of the renal transplant recipients was 13.50 ± 3.40 years old. Mean evaluation time after transplantation was 2.0 ± 0.5 years. Bender-Gestalt Test result was abnormal in 40% of patients. The results of the Cancellation Test and the Visual and Auditory Number Assay Test showed significant decline in pediatric renal transplant patients when compared with the control. We found that neurocognitive dysfunction was frequent in pediatric renal transplantation patients. Awareness of this potential problem may be helpful for early recognition and treatment. Our findings suggest that periodic neurocognitive assessments may be indicated in transplant recipients.

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

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

    Between January 1976 and March 1982, 28 episodes of pneumonia occurred in 26 renal transplant patients. The overall mortality rate was 46%. Of the 16 patients with nosocomial pneumonia 9 (56%) died, whereas of the 12 patients with community-acquired pneumonia 4 (33%) died. In all 9 cases of unknown cause the response to empiric treatment was prompt, whereas in 4 of the 10 cases of monomicrobial pneumonia and 8 of the 9 cases of polymicrobial pneumonia the patient died. Cytomegalovirus was the sole cause of the pneumonia in two patients and a contributing cause, along with aerobic gram-negative bacteria, in another five, four of whom also had a fungal infection. Two patients, both of whom survived, had nosocomial Legionnaires' disease. PMID:6342741

    The /sup 99m/Tc-DTPA renogram is a well extabished noninvasive method for evaluating and following transplanted kidneys. The examination is useful in distinguishing rejection from acute tubular necrosis as well as demonstrating several less common complications such as vascular occlusion, urinary extravasation, obstruction, and lymphocele. A previously unreported condition involving a transplant kidney (i.e., renal cortical necrosis) is described which was diagnosed with renal scintigraphy in combination with sonography.

    Kidney injury is associated with increased morbidity and mortality in liver transplant recipients. Since the introduction of the model for end-stage liver disease for the allocation of organs for liver transplantation in 2002, the heavy weighting of serum creatinine in the model for end-stage liver disease score has significantly increased the incidence of renal dysfunction seen among patients undergoing liver transplantation. As a result, the frequency of simultaneous liver-kidney (SLK) transplantation compared to liver transplantation alone (LTA) has also increased. The decision to perform SLK rather than LTA is an important one because the benefits to the liver transplant recipient receiving a kidney transplant must be balanced with the benefits of using that organ for a patient with end-stage renal disease. However, predicting whether or not a patient with liver failure has reversible kidney disease, and therefore does not also need a kidney transplant, is difficult. The severity and duration of pretransplant renal dysfunction, hepatitis c, diabetes, and other risk factors for kidney disease are associated with an increased risk of posttransplant end-stage renal disease. However, there are currently no clinical findings that accurately predict renal recovery post liver transplant. As a result, the rate of SLK versus LTA differs significantly between transplant centers. To increase consistency across centers, multiple guidelines have been proposed to guide the decision between SLK and LTA, but their poor predictive value has limited their uniform adoption. Nevertheless, adoption of uniform rules for the allocation of kidneys would reduce the variability between centers in rates of SLK transplant.

    Women with end-stage renal disease or on regular dialysis have low fertility. Renal transplantation restores not only normal renal and endocrine functions but also the reproductive function as well and this conception becomes possible. Pregnancy in transplanted women is at higher risk and necessitates a multidisciplinary follow up. We report the course and out come of two successful pregnancies, the second was the first case of twin pregnancy in Tunisia in a transplanted woman. Our patient is 35 years old had a chronic renal insufficiency, secondary to interstitial nephropathy. After six years of hemodialysis, she had received a renal graft from a living donor (his brother). A double drug immunosuppression was given (Prednisolone - Azathioprine). Two years later, she became pregnant and delivered a normal baby at term, and one year later she had a twin pregnancy that ended successfully and delivered by caesarian section a two babies with different sex. Pregnancy after renal transplantion must be considered as a risk factor for any subsquent pregnancy, and the risk nicreases in case of twin pregnancy.

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

    Kidney transplantation has become a preferred treatment for end-stage renal disease (ESRD) as transplant recipients enjoy freedom from dialysis and improvement in both quality and quantity of life. More patients are being placed on the transplant waiting list, although the waiting list patients still only represent a very small fraction of ESRD patients. The characteristics of both waitlisted and transplanted patients have changed considerably in the last decade, as the ESRD population has aged and waiting list times have increased. Over the last 10 years, we have witnessed an increasingly severe shortage of kidney donors. Even with increasing efforts of the transplant community to expand the donor pool by including larger numbers of high risk deceased donor transplants, the overall number of kidney transplants has remained relatively stable. Those who do receive transplants, however, benefit from excellent transplant outcomes. The use of paired exchange/chain transplant donors has increased the living donor pool significantly and with outstanding results. Belatacept, a costimulation blockage drug, represents a new class of transplant immunosuppression. It has been used sparingly in the first few years of its approval. Most kidney transplant patients are still maintained on immunosuppressive agents that were approved almost two decades ago. In the next decade, we will certainly continue to deal with an organ shortage as the number of eligible and waitlisted patients is likely to increase. Effective and efficient organ allocation policies will be increasingly necessary to address this scarcity. Optimizing the transplant candidate work-up, improving maintenance of waitlisted patients, and providing optimal post-transplant medical care will be vital to the continued success of kidney transplantation.

    Hepatitis C virus (HCV) infection is the main cause of liver disease after renal transplantation. Most patients have seroconverted on dialysis to positive RNA. The viral load increases during immunosuppressive therapy. The risk of developing chronic liver disease is related to the histopathologic findings, duration and severity of the disease, immunosuppression, and transplantation time. Hepatitis C virus infection can predict onset, of proteinuria and diabetes. We studied 868 patients who received renal transplants between (1987 and 2006), of whom 18.7% were seropositive for HCV. We observed a higher rate of HCV-seropositive patients related to the duration of hemodialysis therapy. Of the HCV seropositive patients, 77% had received renal allografts before 1998. There was no difference between the sexes; however, the HCV positive patients were younger. Polymerase chain reaction tests results were positive in 91.6% of the patients with HCV antibodies. The prevalence of diabetes was greater among HCV positive patients, as was as the persistence of proteinuria. Cryoglobulins were positive in 30.8%. The incidence of acute rejection episodes in the first year was similar between groups. Of the HCV-positive patients, 80.2% were treated with cyclosporine, most patients continued this therapy throughout the study. We observed no significant difference in mortality end graft survival rate between the two groups. However, renal function differed significantly at some points during the evolution of the clinical course. Renal transplantation is still the best treatment option in patients with chronic renal disease.

    The supply of deceased donor kidneys is inadequate to meet demand. To expand the pool of potential donors, ABO-incompatible transplants from living donors have been performed. We present the Mayo Clinic experience with such transplants. Enrollment was open to patients when the only available potential living kidney donor was ABO-incompatible. Conditioning consisted of plasma exchanges followed by intravenous immunoglobulin. Splenectomy was performed at the time of transplant surgery. Post-transplant immunosuppression consisted of anti-T lymphocyte antibody, tacrolimus, mycophenolate mofetil, and prednisone. Isoagglutinin titers and scores were determined before and after each plasma exchange. Transplant outcomes were determined. Twenty-six ABO-incompatible transplants were performed. No hyperacute rejection occurred. Mean patient follow-up was 400 days. Patient and graft survivals at last follow-up were 92 and 85%, respectively. Antibody-mediated rejection occurred in 46% and was apparently reversed in 83% by plasma exchange and increased immunosuppression. The initial plasma exchange reduced immediate spin and AHG hemagglutination reactivity scores by 53.5 and 34.6%, respectively. Over the course of the pretransplant plasma exchanges, the immediate spin and AHG hemagglutination reactivity scores decreased by 96.4 and 68.5%, respectively. At 3 and 12 months, the immediate spin and AHG hemagglutinin reactivity scores and titers were less than those at baseline but greater than or equal to those on the day of transplantation. Despite an increase in scores and titers, antibody-mediated rejection was not present. Pre-transplant plasma exchange conditioning combined with other immunosuppressives can be used to prepare patients for ABO-incompatible kidney transplantation from living donors, but antibody-mediated rejection post-transplant is a common occurrence and allograft survival may be reduced. Controlled clinical trials are needed to identify the optimum

    Summary Five patients with end-stage renal disease received combined bone marrow and kidney transplants from HLA single-haplotype mismatched living related donors, with the use of a nonmyeloablative preparative regimen. Transient chimerism and reversible capillary leak syndrome developed in all recipients. Irreversible humoral rejection occurred in one patient. In the other four recipients, it was possible to discontinue all immunosuppressive therapy 9 to 14 months after the transplantation, and renal function has remained stable for 2.0 to 5.3 years since transplantation. The T cells from these four recipients, tested in vitro, showed donor-specific unresponsiveness and in specimens from allograft biopsies, obtained after withdrawal of immunosuppressive therapy, there were high levels of P3 (FOXP3) messenger RNA (mRNA) but not granzyme B mRNA.

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

    99mTc-DTPA scintigraphy was evaluated in seven patients as a technique to assess perfusion of the transplanted pancreas and kidney. Such scans provide high-quality images of both organs in both the flow phase and later phases. The radionuclide is readily available and its brief effective half-life allows repeated evaluations at short intervals. /sup 131/I-hippuran, the major radiopharmaceutical for renal transplant scintigraphy, does not allow visualization of the transplanted pancreas or evaluation of its blood supply. Although the blood glucose is a gross indicator of the function of the pancreatic allograft, pancreatic scintigraphy with 99mTc-DTPA in one case was capable of detecting graft dysfunction before elevation of the blood glucose occurred. While additional studies will be necessary to determine the predictive value of this test, 99mTc-DTPA is valuable for pancreatic-renal transplant evaluation.

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

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

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

    Paracoccidioidomycosis (PCM) is the most common endemic mycosis in Latin America. The etiological agents, which comprise two species, Paracoccidioides brasiliensis and P. lutzii, are thermodimorphic fungi that usually affect previously healthy adults. They primarily involve the lungs and then disseminate to other organs. Such mycosis is rare in organ transplant recipients; there have been only three cases reported in literature, until now. We report a case of PCM in a renal transplant recipient with an unusual dermatological presentation. PMID:26910451

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

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

  17. The feasibility and applications of non-invasive cardiac output monitoring, thromboelastography and transit-time flow measurement in living-related renal transplantation surgery: results of a prospective pilot observational study

    PubMed Central

    2014-01-01

    Introduction Delayed graft function (DGF) remains a significant and detrimental postoperative phenomenon following living-related renal allograft transplantation, with a published incidence of up to 15%. Early therapeutic vasodilatory interventions have been shown to improve DGF, and modifications to immunosuppressive regimens may subsequently lessen its impact. This pilot study assesses the potential applicability of perioperative non-invasive cardiac output monitoring (NICOM), transit-time flow monitoring (TTFM) of the transplant renal artery and pre-/perioperative thromboelastography (TEG) in the early prediction of DGF and perioperative complications. Methods Ten consecutive living-related renal allograft recipients were studied. Non-invasive cardiac output monitoring commenced immediately following induction of anaesthesia and was maintained throughout the perioperative period. Doppler-based TTFM was performed during natural haemostatic pauses in the transplant surgery: immediately following graft reperfusion and following ureteric implantation. Central venous blood sampling for TEG was performed following induction of anaesthesia and during abdominal closure. Results A single incidence of DGF was seen within the studied cohort and one intra-operative (thrombotic) complication noted. NICOM confirmed a predictable trend of increased cardiac index (CI) following allograft reperfusion (mean CI - clamped: 3.17 ± 0.29 L/min/m2, post-reperfusion: 3.50 ± 0.35 L/min/m2; P < 0.05) mediated by a significant reduction in total peripheral resistance. Reduced TTFM at the point of allograft reperfusion (227 ml/min c.f. mean; 411 ml/min (95% CI: 358 to 465)) was identified in a subject who experienced intra-operative transplant renal artery thrombosis. TEG data exhibited significant reductions in clot lysis (LY30 (%): pre-op: 1.0 (0.29 to 1.71), post reperfusion 0.33 (0.15 to 0.80); P = 0.02) and a trend towards increased clot initiation following

    Background: Lung diseases are one of the major causes of morbidity and mortality after renal transplantation. The aim of the study is to define the risk factors for infectious and noninfectious pulmonary complications in kidney transplant patients. Materials and Methods: We prospectively studied 267 patients after renal transplantation. The kidney recipients were followed-up for the development of pulmonary complications for a period of 7 years. Different noninvasive and invasive diagnostic tests were used in cases suspected of lung disease. Results: The risk factors associated with the development of pulmonary complications were diabetes mellitus (odds ratio [OR] = 4.60; P = 0.001), arterial hypertension (OR = 1.95; P = 0.015), living related donor (OR = 2.69; P = 0.004), therapy for acute graft rejection (OR = 2.06; P = 0.038), immunosuppressive regimens that includes mycophenolate (OR = 2.40; P = 0.011), azathioprine (OR = 2.25; P = 0.023), and tacrolimus (OR = 1.83; P = 0.041). The only factor associated with the lower risk of complications was a positive serology test for Cytomegalovirus of the recipient before transplantation (OR = 0.1412; P = 0.001). Conclusion: The risk factors can be used to identify patients at increased risk for posttransplant lung diseases. Monitoring of higher-risk patients allow timely diagnosis and early adequate treatment and can reduce the morbidity and mortality after renal transplantation. PMID:26958045

    Six patients (five men and one woman) with Alport's syndrome underwent successful renal transplantation (four received kidneys from cadaver donors and two received allografts from living, related donors). One patient who had received a cadaver kidney had substantial hearing improvement and the others had stabilization of hearing. Hearing loss in Alport's syndrome is progressive. The reversal of deafness in one of our patients and stabilization in the others made us wonder whether an inherited enzymopathy had been reversed, which then mitigated the deafness.

    The Oman Renal Transplantation Program was established in 1988 as a joint venture between Sultan Qaboos University and the Ministry of Health. It began with both living related donor (LRD) and deceased donor (DD) transplants. Over the next nine years, while the LRD programme progressed relatively well, there were only thirteen DD transplants. Two of the DD kidneys were obtained from overseas via an active collaboration with the Euro-transplant organisation, and one DD kidney was obtained from Saudi Arabia within the Gulf Cooperative Council exchange programme. The rest of the DD kidneys were obtained in Oman. The Omani DD programme, although it was a pioneering effort in the Gulf region at the time, was not entirely sustainable. In this paper we focus on the challenges we encountered. Among the major challenges was the absence of resources to establish a dedicated DD programme and particularly the failure to develop a cadre of dedicated transplant coordinators.

    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with <6 weeks on dialysis. 66% of our patients were 30-60 years old; 98% of the patients had living donors. At transplantation, 64% of our patients had no public support; however, 64% of them returned to work and got health insurance 2 months later. Full rehabilitation was achieved in all cases, including integration to the family, return to full-time work, school and university, sports, and reproduction. Immunosuppression consisted of 3 drugs, including steroids, cyclosporine, and azathioprine or mycophenolate. The cost in the 1st year, including patient and donor evaluation, surgery, immunosuppression, and follow-up, was $13,300 USD versus $22,320 for hemodialysis. We conclude that preemptive renal transplantation with <6 weeks on dialysis is the best therapeutic option for end-stage renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

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

    INTRODUCTION: Our study presents an analysis of the trends of ABO antibody titers and the TPE (Therapeutic Plasma Exchange) procedures required pre and post ABO incompatible renal transplant. MATERIALS AND METHODS: Twenty nine patients underwent ABO incompatible renal transplant during the study period. The ABO antibody titers were done using the tube technique and titer reported was the dilution at which 1+ reaction was observed. The baseline titers of anti-A and anti-B antibodies were determined. The titer targeted was ≤8. Patients were subjected to 1 plasma volume exchange with 5% albumin and 2 units of AB group FFP (Fresh Frozen Plasma) in each sitting. TPE procedures post-transplant were decided on the basis of rising antibody titer with/ without graft dysfunction. RESULTS: The average number of TPE procedures required was 4-5 procedures/patient in the pretransplant and 2-3/patient in the post-transplant period. An average titer reduction of 1 serial dilution/procedure was noted for Anti-A and 1.1/procedure for Anti-B. Number of procedures required to reach the target titer was not significantly different for Anti-A and Anti-B (P = 0.98). Outcome of the transplant did not differ significantly by reducing titers to a level less than 8 (P = 0.32). The difference in the Anti-A and Anti-B titers at 14th day post-transplant was found to be clinically significant (P = 0.042). CONCLUSION: With an average of 4-5 TPE procedures pretransplant and 2-3 TPE procedures post transplants, ABO incompatible renal transplantations can be successfully accomplished. PMID:28316440

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

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

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

    Kidney transplantation is the key for patients with end-stage renal disease, improving quality of life and longer survival. However, kidney transplant triggers an intense inflammatory response and alters the hemostatic system, but the pathophysiological mechanisms of these changes are not completely understood. The aim of this cross-sectional cohort study was to investigate hemostatic biomarkers in Brazilian renal transplanted patients according to renal function and time after transplantation. A total of 159 renal transplanted patients were enrolled and D-Dimer (D-Di), Thrombomodulin (TM), von Willebrand Factor (VWF), and ADAMTS13 plasma levels were assessed by ELISA. An increase of D-Di was observed in patients with higher levels of creatinine. ADAMTS13 levels were associated with creatinine plasma levels and D-Di levels with Glomerular Filtration Rate. These results suggested that D-Di and ADAMTS13 can be promising markers to estimate renal function. ADAMTS13 should be investigated throughout the posttransplant time to clarify the participation of this enzyme in glomerular filtration and acceptance or rejection of the graft in Brazilian transplanted patients.

    The use of cyclosporine and tacrolimus therapy in nonrenal (heart, heart/lung, lung, and liver) transplantation has resulted in improved patient and graft survival. Nephrotoxicity is one of the major side effects of tacrolimus and cyclosporine therapy and may lead to ESRD. The trend of referral of nonrenal solid-organ transplant recipients for kidney transplant evaluation at a large multiorgan transplant center was examined. Records of all patients who were referred for renal transplantation at the University of Alabama between January 1, 1993, and June 30, 2004, were reviewed. Eighty (0.96%) of 8318 individuals had previously undergone a nonrenal solid-organ transplant and were included in the study. The majority (72%) of patients had their nonrenal transplants performed at the University of Alabama. Twenty-two patients had their nonrenal transplant performed elsewhere and had fewer data available for analysis. From the period 1993-1996 to 2001-2004, an 11-fold increase in the absolute number of referrals of patients with nonrenal transplants was noted. Of patients who were referred for transplant evaluation, 25 became recipients of kidney transplants with a predominance of living-donor transplants. Referral for kidney transplant evaluation among nonrenal solid-organ transplant recipients is increasing and will exacerbate the existing shortage of deceased-donor kidneys that are available for transplantation. There was a trend for liver transplant recipients compared with other solid-organ recipients to develop ESRD at a greater rate.

    Kidney transplantation has become the treatment of choice for end-stage renal disease. However, its application is limited due to inadequate organ supply, mainly because many dialysis patients do not have suitable living donors. The increasing discrepancy between organ supply and demand has forced many transplant centers to consider using organs procured from marginal donors. The aim of this study was to investigate whether utilization of kidneys from living related elderly donors is safe for the recipients in the long term. We analyzed the clinical results of 296 consecutive recipients of living related renal transplants, among whom 44 recipients received kidneys from donors over 60 years of age. By the end of 12 months, the mean serum creatinine level of the recipients who were transplanted from the older donors was higher (1.55 +/- 0.45 mg/dL) than that from other donors (1.21 +/- 0.3 mg/dL), but the difference was not significant (P = .08). In the long term (60 months), the graft function was similar (1.88 +/- 0.55 vs 1.52 +/- 0.38) for both groups. The similarity in outcomes of ideal versus older donors as shown less in the present series has encouraged us to utilize elderly living donors. We concluded that transplantations performed from the elderly donors yielded similar results to those of conventional donors. The long waiting list for transplantation, the treatment of choice for end-stage renal disease, should encourage us to be more flexible about donor selection.

    2015-12-01

    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.

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

    Brunei Darussalam is a small Muslim country with a high prevalence and incidence of kidney disease. At present, there is no local transplant program for patients on the renal replacement therapy program. In order to assess feasibility of a local transplant program, we decided to conduct a survey to assess public opinion on renal transplantation. The majority of the 300 respondents (78.7%) were willing to donate their kidneys if needed. Even after learning of the small theoretical risks of kidney failure, 72.33% of all respondents were still willing to proceed with transplantation. Respondents who had relatives on dialysis and who had a higher education level were more willing to donate their kidneys. There was no significant difference between Muslims and non-Muslims. Most respondents (59.7%) preferred to have transplantation done locally. This study shows that most Bruneians are receptive of the idea of living related kidney donations, which augurs well for the sustainability of a new program. More work is needed to overcome other barriers like the availability of surgical expertise and facilities and cost-benefit considerations.

  13. Overview of Pregnancy in Renal Transplant Patients

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

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

    We describe a patient with severe pulmonary arterial hypertension scheduled to undergo live-related renal transplantation. We emphasise on meticulous anaesthetic management and early renal transplantation to prevent the progression of disease which would become refractory to treatment, leading to right ventricular failure. Regional (continuous epidural) anaesthesia has been used as technique of choice, where the selective advantages of this technique have been put to good use. PMID:28250487

    Polydipsia and polyuria are common symptoms in patients with diabetes insipidus (DI), which can be due to inadequate vasopressin production (cranial DI) or vasopressin insensitivity (nephrogenic DI). Clinical diagnosis of the subtypes of DI can be tricky. We present a 44-year-old man with a strong family history of DI who had been diagnosed with autosomal dominant nephrogenic DI from infancy. At the age of 40, he had progressed to end-stage renal failure. When he experienced unresolving severe polyuria after renal transplant, further investigations revealed that he was misdiagnosed and that he had a novel mutation causing autosomal dominant cranial DI.

    Evidence is accumulating indicating a role for uric acid in the genesis and progression of kidney disease, and a few studies are beginning to show a possible beneficial effect of urate-lowering therapy. Whether this holds true for renal allograft recipients is not clear. In this short review evidence from epidemiological as well as intervention studies is summarized and discussed, with some practical considerations presented at the end. PMID:26167455

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

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

  20. Use of the inferior epigastric artery to revascularize a lower pole renal artery in renal transplant.

    PubMed

    1995-02-01

    The increasing use of living-related donors has increased the incidence wherein the transplant surgeon is required to use special vascular surgical techniques to transplant kidneys with anomalous arterial anatomy. One of the most commonly encountered arterial anomalies is the presence of a lower pole renal artery. In many cases, this artery can be anastomosed to the main renal artery, and the main renal artery can then be anastomosed into the recipient vessel. However, there are cases where the lower pole renal artery is too distant from the main renal artery to allow an anastomosis to be performed. The lower pole renal artery of the graft must be revascularized to avoid ischemic injury to the ureter. Thus, alternate methods for the revascularization of this vessel must be found. We describe the use of the recipient inferior epigastric artery as an arterial supply for the donor lower pole artery. In our case report, this method provided excellent flow to the lower kidney and was documented by later studies.

    A computer analysis of post renal transplantation gastrointestinal problems was performed to identify important associated clinical factors. Thirty-seven per cent of all transplant recipients developed one or more significant problems. Hemorrhage, nondiverticular intestinal perforation, and esophagitis occurred most frequently in hospitalized patients. Pancreatitis, diverticulitis, and gastroduodenal perforation occurred characteristically in long-term survivors with well functioning allografts. Eleven of 32 HLA identical recipients treated with maintenance corticosteroids during stable kidney function developed gastrointestinal disease while only one of 13 HLA identical recipients not given maintenance steroids developed a problem, which strongly suggests a causal role for steroids in the development of late complications. The association of preexisting peptic ulcer and diverticular disease with hemorrhage and perforation supports previous recommendations that documented peptic ulcer disease or diverticulitis should be corrected surgically prior to transplantation.

    A variety of skin infections are encountered in postrenal transplant setting. Though bacterial and fungal infections are more common, surprises are in store for us sometimes. We describe a patient who underwent renal transplant two years ago, presenting with a painless, mildly pruritic expanding skin rash over abdomen. Histological examination of the skin biopsy showed that stratum corneum had multiple burrows containing larvae and eggs of Sarcoptes scabiei. The patient was treated with ivermectin 12 mg weekly once for 2 doses along with topical 5% permethrin and permethrin soap bath. There was remarkable improvement in the skin lesions with complete resolution in two weeks. Norwegian or crusted scabies is caused by massive infestation with Sarcoptes scabiei var. hominis. It can be rarely encountered in the post-transplant setting, which underscores the importance of early diagnosis and treatment before secondary bacterial infection sets in. PMID:20835323

    2010-05-01

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

    Blood pressure (BP) control at home is difficult when managed only with office blood pressure monitoring (OBPM). In this prospective study, the reliability of BP measurements in renal transplant patients with OBPM and home blood pressure monitoring (HBPM) was compared with ambulatory blood pressure monitoring (ABPM) as the gold standard. Adult patients who had living-related renal transplantation from March 2007 to February 2008 had BP measured by two methods; OBPM and ABPM at pretransplantation, 2(nd), 4(th), 6(th), and 9(th) months and all the three methods: OBPM, ABPM, and HBPM at 6 months after transplantation. A total of 49 patients, age 35 ± 11 years, on prednisolone, tacrolimus, and mycophenolate were evaluated. A total of 39 were males (79.6%). Systolic BP (SBP) and diastolic BP (DBP) measured by OBPM were higher than HBPM when compared with ABPM. When assessed using OBPM and awake ABPM, both SBP and DBP were significantly overestimated by OBPM with mean difference of 3-12 mm Hg by office SBP and 6-8 mm Hg for office DBP. When HBPM was compared with mean ABPM at 6 months both the SBP and DBP were overestimated by and 7 mm Hg respectively. At 6 months post transplantation, when compared with ABPM, OBPM was more specific than HBPM in diagnosing hypertension (98% specificity, Kappa: 0.88 vs. 89% specificity, Kappa: 0.71). HBPM was superior to OBPM in identifying patients achieving goal BP (89% specificity, Kappa: 0.71 vs. 50% specificity Kappa: 0.54). In the absence of a gold standard for comparison the latent class model analysis still showed that ABPM was the best tool for diagnosing hypertension and monitoring patients reaching targeted control. OBPM remains an important tool for the diagnosis and management of hypertension in renal transplant recipients. HBPM and ABPM could be used to achieve BP control.

    In a diabetic renal transplant recipient a nephrocutaneous fistula developed after percutaneous renal graft biopsy, and ureteral obstruction due to Candida albicans fungus balls was demonstrated. Local irrigation with amphotericin B, systemic antifungal therapy, and rigid blood sugar control led to rapid clearing of the fungal infections. This cause of renal transplant insufficiency should be considered prior to renal biopsy in diabetic patients with yeast forms in the urine.

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

    Objectives: Oral candidiasis (OC) is a frequent oral lesion in renal transplant patients (RTPs). Despite the increased prevalence of OC in RTPs, no study has examined related risk factors. The aims of this study were to analyze the prevalence of and risk factors for OC in RTPs compared with age- and gender-matched healthy control group (HC) as well as determine the incidence of OC after transplantation. Study Design: We analyzed the prevalence and risk factors of OC in a group of 500 RTPs (307 men, 193 women, mean age 53.63 years) and 501 HC subjects (314 men, 187 women, mean age 52.25 years). Demographic and pharmacological data were recorded for all subjects. Incident cases of OC were ascertained retrospectively from outpatient clinical records only in the RTP group. Results: The prevalence of OC was 7.4% in RTPs compared with 4.19% in HC (P<0.03). The most frequent type of OC in the two groups was denture stomatitis. Statistical association was found between OC and age, mycophenolate mofetil dose and blood levels, dentures and tobacco. The multiple logistic regression model only chose for denture variable. According to the outpatient clinical records, 24 RTPs suffered OC during the first moth post-transplant. Severe lesions affecting the oral cavity and pharynx appeared in 79% of the OC cases. Conclusions: This study shows a lower prevalence of OC in RTPs than previous reports. Denture stomatitis was the most frequent OC prevalence form described in RTPs. Severe candidiasis is more frequent in the immediate posttransplant period. The presence of denture is an important risk factor of OC. These results emphasise the importance of adequate pre- and post-transplant oral health and denture cleaning and adjustment is recommended for these subjects to prevent this infection. Key words:Oral candidiasis, immunosuppressive therapy, renal transplantation. PMID:23385511

  13. Commercial renal transplantation: A risky venture? A single Canadian centre experience

    PubMed Central

    Kapoor, Anil; Kwan, Kevin G.; Whelan, J. Paul

    2011-01-01

    Background: Canada, akin to other developed nations, faces the growing challenges of end-stage renal disease (ESRD). Even with expanded donor criteria for renal transplantation (the treatment of choice for ESRD), the supply of kidneys is outpaced by the escalating demand. Remuneration for kidney donation is proscribed in Canada. Without an option of living-related transplantation (biological or emotional donors), patients often struggle with long waiting lists for deceased donor transplantation. Accordingly, many patients are now opting for more expedient avenues to obtaining a renal transplant. Through commercial organ retrieval programs, from living and deceased donors, patients are travelling outside Canada to have the procedure performed. Methods: Between September 2001 and July 2007, 10 patients (7 males, 3 females) underwent commercial renal transplantation outside Canada. We describe the clinical outcomes of these patients managed postoperatively at our single Canadian transplant centre. Results: Six living unrelated and 4 deceased donor renal transplantations were performed on these 10 patients (mean age 49.5 years). All procedures were performed in developing countries and the postoperative complications were subsequently treated at our centre. The mean post-transplant serum creatinine was 142 μmol/L. The average follow-up time was 29.8 months (range: 3 to 73 months). One patient required a transplant nephrectomy secondary to fungemia and subsequently died. One patient had a failed transplant and has currently resumed hemodialysis. Acute rejection was seen in 5 patients with 3 of these patients requiring re-initiation of hemodialysis. Only 1 patient had an uncomplicated course after surgery. Discussion: Despite the kidney trade being a milieu of corruption and commercialization, and the high risk of unconventional complications, patients returning to Canada after commercial renal transplantation are the new reality. Patients are often arriving without any

    The shortage of deceased donor liver grafts led to the use of living donor liver transplant (LDLT). Patients who undergo LDLT have a higher risk of complications than those who undergo deceased donor liver transplantation (LT). Interventional radiology has acquired a key role in every LT program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplant. The aim of this paper is to review indications, diagnostic modalities, technical considerations, achievements and potential complications of interventional radiology procedures after LDLT.

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

    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.

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

    Secondary hyperparathyroidism contributes to post-transplant CKD mineral and bone disorder. Paricalcitol, a selective vitamin D receptor activator, decreased serum parathyroid hormone levels and proteinuria in patients with secondary hyperparathyroidism. This single-center, prospective, randomized, crossover, open-label study compared the effect of 6-month treatment with paricalcitol (1 μg/d for 3 months and then uptitrated to 2 µg/d if tolerated) or nonparicalcitol therapy on serum parathyroid hormone levels (primary outcome), mineral metabolism, and proteinuria in 43 consenting recipients of renal transplants with secondary hyperparathyroidism. Participants were randomized 1:1 according to a computer-generated sequence. Compared with baseline, median (interquartile range) serum parathyroid hormone levels significantly declined on paricalcitol from 115.6 (94.8–152.0) to 63.3 (52.0–79.7) pg/ml (P<0.001) but not on nonparicalcitol therapy. At 6 months, levels significantly differed between treatments (P<0.001 by analysis of covariance). Serum bone-specific alkaline phosphatase and osteocalcin decreased on paricalcitol therapy only and significantly differed between treatments at 6 months (P<0.001 for all comparisons). At 6 months, urinary deoxypyridinoline-to-creatinine ratio and 24-hour proteinuria level decreased only on paricalcitol (P<0.05). L3 and L4 vertebral mineral bone density, assessed by dual-energy x-ray absorption, significantly improved with paricalcitol at 6 months (P<0.05 for both densities). Paricalcitol was well tolerated. Overall, 6-month paricalcitol supplementation reduced parathyroid hormone levels and proteinuria, attenuated bone remodeling and mineral loss, and reduced eGFR in renal transplant recipients with secondary hyperparathyroidism. Long-term studies are needed to monitor directly measured GFR, ensure that the bone remodeling and mineral effects are sustained, and determine if the reduction in proteinuria improves renal and

There was fluid accumulation in 69 patients, distributed between 31 perirenal haematoma. 17 lymphocele, 13 urinoma, 5 perirenal abscesses and 3 mixed. 27.7% required no action. Frequency of renal rupture was 18 cases, 9 due to acute rejection and 9 to vascular thrombosis. Incidence of urinary obstruction was 4.8% with 5.8% of urinary fistula. With regard to the surgical wound, 9 infections, 7 haematomas, 1 eventration and 1 necrotizing fasciitis were observed. Vascular complications consisted in 10 arterial thrombosis, 10 venous thrombosis, 5 mixed thrombosis and 31 arterial stenosis. Treatment instituted for the various cases, its evolution, and an statistical study of risk factors are illustrated.

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

    Hepatitis C virus, which usually starts during dialysis therapy, is currently the main cause of chronic liver disease in such population. The majority of patients acquired the disease through intravenous drug use or blood transfusion, with some risk factors identified. In this review we are dealing with the effect of renal transplantation on HCV infection and HCV-related complications after renal transplantation. Moreover, we are discussing the therapeutic options of HCV infection before and after renal transplantation, the best immunosuppressive protocol and lastly graft and patient survival in patients who underwent pretransplant management vs. those who were transplanted without treatment.

    Living donor liver transplantation (LDLT) sparked significant interest in Europe when the first reports of its success from USA and Asia were made public. Many transplant programs initiated LDLT and some of them especially in Germany and Belgium became a point of reference for many patients and important contributors to the advancement of the field. After the initial enthusiasm, most of the European programs stopped performing LDLT and today the overall European activity is concentrated in a few centers and the number of living donor liver transplants is only a single digit fraction of the overall number of liver transplants performed. In this paper we analyse the present European activities and highlight the European contribution to the advancement of the field of LDLT. PMID:27115011

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

    Over a seven-year period 18 of 125 patients who underwent renal transplantation developed hepatitis. Acute hepatic necrosis occurred in two, chronic aggressive hepatitis progressing to posthepatitic cirrhosis in eight, chronic persistent hepatitis in five, acute hepatitis with recovery in two and cholestatic hepatitis in one. Hepatic failure was the cause of death in four and a major contributing factor in three. Fifteen of the 18 were of blood Group A. After renal transplantation Australia antigen (Au) was present in the blood of 12 of the 15 patients with hepatitis who were tested and in one of 38 patients without clinical evidence of liver disease. Once present, Au persisted in all patients but one. Particles measuring 210 to 250 Å, characteristic of Au, were seen in liver cells by electronmicroscopy in nine of the 10 patients examined who had hepatitis with Australia antigenemia, but they were not seen in the two patients studied with Au-negative hepatitis.

    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.

    2012-01-01

    The persistence and severity of hyperparathyroidism (HPT) post-renal transplantation is relatively frequent and primarily associated with the timing and its magnitude in the pre-transplant period and with the presence of parathyroid adenomas. HPT after renal transplantation is clinically manifested with hypercalcemia, hypophosphatemia, bone pain, fractures, and in more serious cases with cardiovascular calcifications that affect the survival. The primary clinical objective for patients with secondary HPT after renal transplantation is to obtain a level of parathyroid hormone (PTH) adequate to the renal transplanted function and to normalize levels of calcium, phosphorus and vitamin D. In many cases during this period, the development of hypercalcemia and/or hypophosphatemia makes it necessary to take different therapeutic measures. The use of vitamin D or its analogues has been extrapolated from the management of pre-transplant HPT obtaining variable outcomes, although its use is limited by its capacity to produce hypercalcemia. Calcimimetics are drugs that have proven be effective in reducing PTH levels in patients with HPT on dialysis and has been effective in reducing up to 50% PTH levels in moderate to severe HPT in post-renal transplantation.When HPT persists after renal transplantation and does not respond to medical treatment, invasive management by percutaneous ethanol injection therapy of parathyroid glands or parathyroidectomy should be considered. The emergence of new methods for the management of HPT expands the availability of therapeutic tools for transplant patients. PMID:24175195

    Following renal transplantation, patients are often evaluated with ultrasonography (US) or radionuclide imaging to assess renal function and the presence of possible complications. Both modalities are inexpensive, noninvasive, and nonnephrotoxic. A basic understanding of the surgical techniques commonly used for renal transplantation is useful when imaging these patients in order to recognize complications and to direct further imaging or intervention. The most frequent complications of renal transplantation include perinephric fluid collections; decreased renal function; and abnormalities of the vasculature, collecting system, and renal parenchyma. Perinephric fluid collections are common following transplantation, and their clinical significance depends on the type, location, size, and growth of the fluid collection, features that are well-evaluated with US. Causes of diminished renal function include acute tubular necrosis, rejection, and toxicity from medications. Radionuclide imaging is the most useful modality for assessing renal function. Vascular complications of transplantation include occlusion or stenosis of the arterial or venous supply, arteriovenous fistulas, and pseudoaneurysms. Although the standard for evaluating these vascular complications is angiography, US is an excellent noninvasive method for screening. Other transplant complications such as abnormalities of the collecting system and renal parenchyma are well-evaluated with both radionuclide imaging and US.

    Gaining long-term graft function and patient survival remain a critical challenge following kidney transplantation. Genetic and environmental factors do not completely account for the individual's graft outcome. Recently, it is reported that gut microbial community (microbiota) is associated with complications in kidney allograft recipients, as well. Commensal microbiota plays a significant role in the immunomodulation of transplant recipient responses. Different factors can disrupt the reciprocal interaction between microbiota and the host immune responses and lead to infection and rejection complications in the organ recipient. In this review, we address the relation between microbiota and immune system along with their possible roles in renal graft outcome. We next highlight the beneficial effects of probiotics on the management of kidney diseases and solid organ transplantation. Finally, we reflect on the potential impacts of probiotics on host physiology. Hopefully, a deeper understanding of the function and composition of microbiota can help clinics develop strategies to restore the normal microbiota and facilitate the clinical management of grafts in the forthcoming future.

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

    2017-01-01

    Background ABO incompatible kidney transplantation (ABOi-KT) is an important approach for overcoming donor shortages. We evaluated the effect of ABOi-KT on living donor KT. Methods Two nationwide transplantation databases were used. We evaluated the impact of ABOi-KT on overall living donor transplant activity and spousal donation as subgroup analysis. In addition, we compared the clinical outcome between ABOi-KT and ABO compatible KT (ABOc-KT) from spousal donor, and performed a Cox proportional hazards regression analysis to define the risk factors affecting the allograft outcomes. Result The introduction of ABOi-KT increased overall living donor KT by 12.2% and its portion was increased from 0.3% to 21.7% during study period. The ABOi-KT in living unrelated KT was two times higher than that of living related donor KT (17.8 vs.9.8%). Spousal donor was a major portion of living unrelated KT (77.6%) and ABOi-KT increased spousal donation from 10% to 31.5% in living donor KT. In addition, increasing rate ABOi-KT from spousal donor was 10 times higher than that of living related donor. The clinical outcome (incidence of acute rejection, allograft function, and allograft and patient survival rates) of ABOi-KT from spousal donor was comparable to that of ABOc-KT. Neither ABO incompatibility nor spousal donor was associated with acute rejection or allograft failure on multivariate analysis. Conclusions ABOi-KT increased overall living donor KT, and ABOi-KT from spousal donor is rapidly increasing with favorable clinical outcomes. PMID:28323892

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

    Renal transplantation is the treatment of choice for end-stage renal disease. Living related kidney donation is the major source of renal grafts due to limited availability of cadaveric kidneys. Open nephrectomy was used to harvest donor kidneys. However, the laparoscopic approach is associated with less postoperative pain and quick recovery. So, most centers now prefer a laparoscopic approach to explant donor kidneys. Laparoscopic approach is technically challenging due to limited operative visibility. Hence, accurate preoperative detection of renal arterial and venous anomalies is imperative to avoid inadvertent vascular injury and bleeding. The preoperative workup of renal donors includes clinical evaluation, laboratory tests, and imaging. Traditionally, the renal donors were evaluated with conventional imaging techniques, which included renal catheter angiography and intravenous urography. However, conventional imaging is invasive, expensive, and less accurate for evaluation of complex renal venous anomalies, small calculi, and diffuse or focal renal parenchymal lesions. The introduction of multidetector row computed tomography (MDCT) revolutionized the CT technology by enabling isotropic resolution with faster scan coverage in a single, short breath-hold. Consequently, MDCT has now replaced conventional imaging for comprehensive imaging of potential living renal donors. MDCT is a minimally invasive technique that can accurately detect urolithiasis, renal arterial and venous anomalies, renal parenchymal lesions, and urinary tract anomalies. Renal vascular anomalies detected by MDCT can help the surgeon in planning donor nephrectomy. MDCT with three-dimensional CT angiography enables accurate preoperative renal vascular mapping. This article reviews the role of MDCT in preoperative evaluation of potential laparoscopic renal donors.

    Racial and ethnic disparities exist in renal transplantation. The causes are multifactorial and include but are not limited to racism, socioeconomic status and class, unfavorable geographical location, lack of organ donation by minority groups, and differences in social networks, health beliefs culture and HLA typing. These disparities affect blacks, Hispanic Americans, Native Americans, Alaskan natiives and Asians. Elimination of these disparities is difficult, since many of the causes are intertwined, and it is difficult todiscern attributable disparity risk associated with the various factors. The possible solutions and recommendations are numerous. Since it is difficult to identify which may be successsful, thorough evaluation is required to determine which should be implemented. Some recommendations may not be easily implemented. Those selected for implementation must be continuously monitored for the expected results and effects. PMID:15712778

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

    Kidney transplantation has dramatically evolved from a life-saving yet unproven therapy for patients with renal failure to a mature field that is the preferred treatment for those suffering from ESRD. Patients who receive a transplant experience a 68% lower risk of death compared with those waiting on dialysis for a transplant. This benefit is afforded to all patient subgroups including the elderly (> or =70 yr), and diabetics, who can gain 11 yr of extra life with transplantation. Prolonged transplant wait times result in a higher risk of death but this can be ameliorated with preemptive transplantation. Future challenges will focus on appropriate organ allocation and addressing long-term renal function and comorbid conditions so patients can enjoy the full benefits of transplantation.

    Since December 1995, pediatric renal transplant recipients in our unit have received a DMSA scan as soon as possible post-transplant in order to provide a baseline for comparison in the event of subsequent complications. We retrospectively reviewed the case notes and DMSA scans of the 45 patients who underwent a scan within 9 wk of their transplant to see if pre or peri-transplant factors or post-transplant complications were associated with defects on scanning. Forty percentage of scans had defects. The presence of defects was not associated with potential predisposing factors such as patient or donor age, cadaveric or live donation, cold ischemia time, multiple donor vessels, the use of non-heart beating donors, the mean time to scan, the serum creatinine, or the presence of structural renal tract anomalies predisposing to UTI. However, 87% of patients had complications before the scan, including UTI, rejection, acute tubular necrosis, transplant biopsy and drug toxicity. Children with no clinical complications had a significantly reduced risk of a defect (p = 0.035), while biopsy was associated with the presence of defects (p = 0.0034). Twenty patients had one or more follow up DMSA scans: one patient developed a new focal defect. In conclusion, renal transplant defects are frequently found on DMSA scanning even early after transplantation and are non-specifically associated with many different complications.

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

    The impact of renal transplantation on trabecular and cortical bone mineral density (BMD) and cortical structure is unknown. We obtained quantitative computed tomography scans of the tibia in pediatric renal transplant recipients at transplantation and 3, 6, and 12 months; 58 recipients completed at least two visits. We used more than 700 reference participants to generate Z-scores for trabecular BMD, cortical BMD, section modulus (a summary measure of cortical dimensions and strength), and muscle and fat area. At baseline, compared with reference participants, renal transplant recipients had significantly lower mean section modulus and muscle area; trabecular BMD was significantly greater than reference participants only in transplant recipients younger than 13 years. After transplantation, trabecular BMD decreased significantly in association with greater glucocorticoid exposure. Cortical BMD increased significantly in association with greater glucocorticoid exposure and greater decreases in parathyroid hormone levels. Muscle and fat area both increased significantly, but section modulus did not improve. At 12 months, transplantation associated with significantly lower section modulus and greater fat area compared with reference participants. Muscle area and cortical BMD did not differ significantly between transplant recipients and reference participants. Trabecular BMD was no longer significantly elevated in younger recipients and was low in older recipients. Pediatric renal transplant associated with persistent deficits in section modulus, despite recovery of muscle, and low trabecular BMD in older recipients. Future studies should determine the implications of these data on fracture risk and identify strategies to improve bone density and structure. PMID:22282589

    A girl aged 11 years and 3 months with occlusion of the inferior vena cava had experienced two renal transplant graft failures since birth. The third renal transplant from a live donor was carried out. Preoperative evaluation showed that the arteries from the right common to the right external iliac artery were absent, and the ilio-caval vein was occluded below the level of the renal vein. The donor's renal artery was anastomosed to the aorta. The donor's ovarian and large saphenous veins were used to extend the transplant renal vein to the recipient's patent inferior vena cava. The present report concludes that the extension of a short donor renal vein using other donor veins is a viable therapeutic option for pediatric patients with vascular occlusions.

    Percutaneous renal biopsy (PRB) is an useful tool for diagnostic and therapeutic orientation in renal transplantation. PURPOSE--To evaluate the current role of PRB in post-transplant acute renal dysfunction (ARD) of renal allografts. METHODS--Sixty-five renal transplant patients were submitted to 95 valid renal biopsies with no major complications. RESULTS--There was disagreement between the clinical and the pathological diagnosis in 28 occasions (29.5%). In 36 cases (37.9%) the results of the pathological examination led to a modification in patient's management. These modifications were most commonly the avoidance or witholding of a steroid pulse (8 cases); nephrectomy of the renal allograft (8 cases); witholding or decrease of cyclosporine dosage (6 cases); giving a steroid pulse (5 cases) and giving antibiotics to treat acute pyelonephritis in 4 cases. The use of kidneys from cadaveric donors was significantly associated with an increased number of biopsies (p < 0.05). CONCLUSION--These results demonstrate that even though several less invasive procedures are currently employed, renal biopsy is still an indispensable method to the management of ARD in renal transplant patients.

    Following The Declaration of Istanbul 2008, a registration committees of The Japan Society for Transplantation and The Japanese Society for Clinical Renal Transplantation planned to establish a new registry and tracking system for renal transplant recipients and donors supported by a Health Labor Sciences Research Grant by The Ministry of Health Labour and Welfare. In place of the previous paper-based system, we established the new registry and tracking system, JARTRE (Japan Renal Transplantation Registry), using USB memory in 2009. Recipient and donor data were inputted into the USB memory at the transplantation centers. The memory was reviewed a yearly by committees. The recipient and donor registration included details from both. The tracking is performed centrally 3 months, 1 year, and every year after the operation. The advantages of this system are the ease of input, adequacy of the data, and rapid statistical processing. In 2009, we registered 97.9% of new renal transplantation recipients and donors; in 2008 it was more than 81.9% of all past renal transplantation recipients in Japan.

These complications have traditionally been managed with open surgical correction, but minimally invasive techniques are being utilized frequently. Materials and Methods. A literature review was performed on the use of endourologic techniques for the management of urologic transplant complications. Results. Ureterovesical anastomotic stricture is the most common long-term urologic complication following renal transplantation. Direct vision endoureterotomy is successful in up to 79% of cases. Urinary leak is the most frequent renal transplant complication early in the postoperative period. Up to 62% of patients have been successfully treated with maximal decompression (nephrostomy tube, ureteral stent, and Foley catheter). Excellent outcomes have been reported following transurethral resection of the prostate shortly after transplantation for patients with urinary retention. Vesicoureteral reflux after renal transplant is common. Deflux injection has been shown to resolve reflux in up to 90% of patients with low-grade disease in the absence of high pressure voiding. Donor-gifted and de novo transplant calculi may be managed with shock wave, ureteroscopic, or percutaneous lithotripsy. Conclusions. Recent advances in equipment and technique have allowed many transplant patients with complications to be effectively managed endoscopically. PMID:24023541

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

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

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

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

    A steroid-free protocol for ABO-compatible renal transplantation has been used at our center since 1983. To minimize the adverse effects of steroids, we also developed a steroid sparing protocol for ABO-incompatible renal transplantation in 2008. The present study is a report of our results. A retrospective review of the first 50 ABO-incompatible renal transplantations performed at a single university center. If no immunological events occurred in the post-transplant period, prednisolone tapering was initiated approximately 3 months after transplantation. Forty-three patients completed prednisolone tapering after 289 ± 58 days. Three patients died during follow-up, and four patients lost graft function. None of these adverse events were rejection related. Eleven patients experienced rejections; seven were on prednisolone and four were after weaning from prednisolone. All patients responded well to antirejection treatment. Overall, 1-year rejection rate was 19%. One- and 3-year graft survival was 94% and 91%, respectively. One-year post-transplant median serum creatinine was 123 μmol/L. We found acceptable rejection rates, graft survival, and creatinine levels in patients undergoing ABO-incompatible renal transplantations with a steroid sparing protocol. However, a longer follow-up of a lager cohort is needed before firm conclusions can be made.

    OBJECTIVE To evaluate the strategies instituted by the authors' center to decrease the time to transplantation and increase the rate of transplantation for African-Americans, consisting of a formal education program concerning the benefits of living organ donation that is oriented to minorities; a laparoscopic living donation program; use of hepatitis C-positive donors in documented positive recipients; and encouraging vaccination for hepatitis B, allowing the use of hepatitis B core Ab-positive donors. SUMMARY BACKGROUND DATA The national shortage of suitable kidney donor organs has disproportional and adverse effects on African-Americans for several reasons. Type II diabetes mellitus and hypertension, major etiologic factors for end-stage renal disease, are more prevalent in African-Americans than in the general population. Once kidney failure has developed, African-Americans are disadvantaged for the following reasons: this patient cohort has longer median waiting times on the renal transplant list; African-Americans have higher rates of acute rejection, which affects long-term allograft survival; and once they are transplanted, the long-term graft survival rates are lower in this population than in other groups. METHODS From March 1990 to November 2001 the authors' center performed 2,167 renal transplants; 944 were in African-Americans (663 primary cadaver renal transplants and 253 primary Living donor renal transplants). The retransplants consisted of 83 cadaver transplants and 17 living donor transplants. Outcome measures of this retrospective analysis included median waiting time, graft and patient survival rates, and the rate of living donation in African-Americans and comparable non-African-Americans. Where applicable, data are compared to United Network for Organ Sharing national statistics. Statistical analysis employed appropriate SPSS applications. RESULTS One- and 5-year patient survival rates for living donor kidneys were 97.1% and 91.3% for non

    Background Renal transplantation is the ideal method for management of end-stage renal disease. The use of living donors for renal transplantation was critical for early development in the field and preceded the use of cadaveric donors. Most donors are related genetically to the recipients, like a parent, a child, or a sibling of the recipient, but there are an increasing percentage of cases where donors are genetically unrelated like spouses, friends, or altruistic individuals. Donor shortages constitute the major barrier for kidney transplantation, and much effort has been made to increase the supply of living donors. The impact of donor source on the outcome of renal transplantation is not adequately studied in our country. Objectives The aim of the study was to evaluate the impact of donor source on the outcome of live donor kidney transplantation. Patients and Methods From March 1976 to December 2013, the number of patients that underwent living renal transplantation sharing at least one HLA haplotype with their donors was 2,485. We divided these patients into two groups: (1) 2,075 kidney transplant recipients (1,554 or 74.9% male and 521 or 25.1% female) for whom the donors were living related, (2) 410 kidney transplant recipients (297 or 72.4% male and 113 or 27.6% female) for whom the donors were living unrelated. All patients received immunosuppressive therapy, consisting of a calcineurin inhibitor, mycophenolate mofetil, or azathioprine and prednisolone. We compared acute rejection and complication rates, as well as long-term graft and patient survival of both groups. Demographic characteristics were compared using the chi-square test. Graft survival and patient survival were calculated using the Kaplan-Meier method. Results The percentages of patients with acute vascular rejection were significantly higher in the unrelated group, while percentages of patients with no rejection were significantly higher in the related group, but there were no significant

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

    From November 3, 1975 to November 3, 1990, 874 kidney transplants were performed at out centers. Of these, 675 (77.2%) were from living donors and 199 (22.8%) were from cadaver donors. Five hundred eighty (66.4%) of the living donors were first degree related while 99 (11.3%) were unrelated or second degree related donors, 29 of which were spouses. All donor recipient pairs were ABO-compatible, with the exception of one pair. Donor recipient relations were wife to husband in 25 cases and husband to wife in 4 cases. All were first grafts and started functioning during surgery. In this series, the follow-up for the recipients was 4 to 64 months (mean 33.5 +/- 4.5 months). One-year patient survival and graft survival rates were 92.4% and 81.9%, respectively. Two-year patient survival and graft survival rates were 92.4% and 78.2%, respectively. The single ABO-incompatible case is also doing well, 21 months postoperatively. This study demonstrates that the interspouse kidney transplantation may be used when cadaver organ shortage is a problem. While providing the couple with a better quality of life, interspouse kidney transplantation also enables the couple to share the joy of giving and receiving the "gift of life" from one another.

    The aim of this retrospective study was to compare the prevalence of pulmonary hypertension in a cohort of patients with end-stage renal disease (ESRD) prior to and following renal transplantation and to identify the possible risk factors. Of the 425 renal transplantations performed between 2001 and 2007, Doppler echocardiographic findings were available in 124. The echocardiographic data, collected both pre- and post-transplant, included the pulmonary artery pressure (PAP), ejection fraction and left ventricular hypertrophy. The data analyzed included age, gender, hypertension, diabetes, smoking status, along with blood urea, creatinine, glomerular filtration rate, hemoglobin, hemodialysis duration, urine albumin, arterio-venous access and body mass index (BMI). Chi-square test was used for discrete variables and ANOVA was used for continuous variables. Of the patients studied, males comprised 72%; the mean age was 43.3 ± 13.02 years; 87% were hypertensive, 30% were diabetic and 4% were smokers. Statistical analysis revealed a significant reduction of the PAP, irrespective of its severity, following renal transplantation (P <0.05). The PAP had no significant correlation with any of the parameters analyzed, with the exception of BMI (P <0.05). Our study suggests that the PAP gets reduced in patients with ESRD after renal transplantation.

    In Egypt there is no doubt that chronic liver diseases are a major health concern. Hepatitis C virus (HCV) prevalence among the 15−59 years age group is estimated to be 14.7%. The high prevalence of chronic liver diseases has led to increasing numbers of Egyptian patients suffering from end stage liver disease (ESLD), necessitating liver transplantation (LT). We reviewed the evolution of LT in Egypt and the current status. A single center was chosen as an example to review the survival and mortality rates. To date, deceased donor liver transplantation (DDLT) has not been implemented in any program though Egyptian Parliament approved the law in 2010. Living donor liver transplantation (LDLT) seemed to be the only logical choice to save many patients who are in desperate need for LT. By that time, there was increase in number of centers doing LDLT (13 centers) and increase in number of LDLT cases [2,400] with improvement of the results. Donor mortality rate is 1.66 per 1,000 donors; this comprised four donors in the Egyptian series. The exact recipient survival is not accurately known however, and the one-year, three-year and five-year survival were 73.17%, 70.83% and 64.16% respectively in the International Medical Center (IMC) in a series of 145 adult to adult living donor liver transplantation (AALDLT) cases. There was no donor mortality in this series. LDLT are now routinely and successfully performed in Egypt with reasonable donor and recipient outcomes. Organ shortage remains the biggest hurdle facing the increasing need for LT. Although LDLT had reasonable outcomes, it carries considerable risks to healthy donors. For example, it lacks cadaveric back up, and is not feasible for all patients. The initial success in LDLT should drive efforts to increase the people awareness about deceased organ donation in Egypt. PMID:27115003

    Results from recent studies have demonstrated that kidney-transplanted patients have better expectation and quality of life than dialysis patients on a waiting list for kidney transplant. Moreover, the scientific literature has conclusively shown that the survival of the patient and of the kidney graft are better in patients who received a kidney from a living donor, than in patients who received a cadaveric kidney. The main factors that may have a negative influence on the kidney transplant are: the recipient's age, diabetes mellitus, smoking and the time spent on dialysis before the transplant. The shortage of cadaveric kidneys and the small number of living kidney transplant are the main obstacles to a more widespread use of kidney transplantation. Kidney transplant from living donors needs to be implemented because it represents the best treatment for patients with kidney failure and it can decrease or even avoid the need for dialysis before kidney transplantation.

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

    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.

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

    Tuberculosis is a disease relatively frequent in renal transplant patients, presenting a wide variety of clinical manifestations, often involving various organs and potentially fatal. Gastrointestinal tuberculosis, although rare in the general population, is about 50 times more frequent in renal transplant patients. Intestinal tuberculosis has a very difficult investigational approach, requiring a high clinical suspicion for its diagnosis. Therapeutic options may be a problem in the context of an immunosuppressed patient, requiring adjustment of maintenance therapy. The authors report two cases of isolated gastro-intestinal tuberculosis in renal transplant recipients that illustrates the difficulty of making this diagnosis and a brief review of the literature on its clinical presentation, diagnosis, and therapeutic approach.

    The number of children undergoing successful renal transplantations has been increasing steadily and as a result; general pediatricians are now more likely to encounter children with a kidney allograft in their practice. Although the medical care immediately after transplantation is mostly provided by transplant teams, more and more outpatient care will eventually be performed at the patient’s local community. Medical care from general pediatricians is particularly important, especially for children who are residing far from transplant centers. As these children require prolong immunosuppressive therapies and are susceptible to various specific clinical problems, it is imperative for their primary care providers and pediatricians to be knowledgeable about their specific needs and be competent in providing care. This article highlights the roles and common practice related issues that pertain to general pediatricians in the care of pediatric renal allograft recipients. PMID:26835261

    A retrospective review was conducted to determine the incidence, etiology, natural history and complications of hyperuricemia after pediatric renal transplantation. Of 81 active transplant recipients aged 10.1 +/- 4.8 (mean +/- SD) years being followed by St. Christopher's Hospital for Children, 57 (70%) were males and 59 (73%) Caucasian. Their immunosuppression consisted of azathioprine, cyclosporine A and prednisone. Mean serum uric acid concentrations peaked at 6 months post transplantation (6.2 +/- 2.6 mg/dl), when 39% of the patients had hyperuricemia and 60% were receiving diuretics, and decreased thereafter. At 30 months, 23% of the patients had hyperuricemia and 17% required diuretics. When we compared 42 normouricemic (group A) with 24 hyperuricemic (group B) patients at 18 months post transplantation, we found that patients in group B were older (11.6 +/- 4.2 vs. 8.6 +/- 5.2 years, P = 0.01), had worse renal function (77 +/- 25 vs. 96 +/- 36 ml/min per 1.73 m2, P = 0.03) and required diuretics more frequently (63% vs. 21%, P = 0.001), but had identical blood levels of cyclosporine A (82 +/- 28 vs. 84 +/- 35 ng/ml, P = 0.78). A family history of gout did not affect the prevalence of hyperuricemia after transplantation. Asymptomatic hyperuricemia is common following pediatric renal transplantation and is more likely attributable to reduced renal function and diuretic therapy than to the known hyperuricemic effect of cyclosporine A. Of these variables, only diuretic therapy is readily controllable and should be closely regulated following pediatric renal transplantation.

    Background. Optimal glycaemic targets following transplantation are unknown. Understanding the impact of DM and posttransplant diabetes mellitus (PTDM) may improve patient and graft survival in transplant recipients. Aim. To determine the perioperative and one-year outcomes after renal transplantation and whether these outcomes are affected by preexisting DM, PTDM, or glycaemia during transplant admission. Method. Adult recipients of renal transplants from a single centre over 5.5 years were retrospectively reviewed. Measured outcomes during transplant admission included glycaemia and complications (infective complications, acute rejection, and return to dialysis) and, at 12 months, glycaemic control and complications (cardiovascular complication, graft failure). Results. Of 148 patients analysed, 29 (19.6%) had DM and 27 (18.2%) developed PTDM. Following transplantation, glucose levels were higher in patients with DM and PTDM. DM patients had a longer hospital stay, had more infections, and were more likely return to dialysis. PTDM patients had increased rates of acute rejection and return to dialysis. At 1 year after transplant, there were more cardiovascular complications in DM patients compared to those without DM. Conclusions. Compared to patients without DM, patients with DM or PTDM are more likely to suffer from complications perioperatively and at 12 months. Perioperative glycaemia is associated with graft function and may be a modifiable risk. PMID:28053992

    We describe here our initial experience with the digital image processing of histopathological aspects from multiple renal biopsies of transplanted kidney in a patient treated with Cyclosporine (CsA), a powerful immunosupressor drug whose use has improved the chances of a successful vascularized organ transplantation (Tx). Unfortunately, CsA promotes morphological alterations to the glomerular structure of the kidneys. To characterize this process, glomeruli, tufts, and lumen areas distributions are measured. The results are presented in form of graphics.

    Passenger lymphocyte syndrome (PLS) is an immune-mediated hemolysis. It occurs following ABO blood group mismatched solid organ and/or bone marrow transplantation between donor and recipient. We report two cases of PLS occurring after renal transplantation. Both recipients received live related kidney transplants; one from his mother and the other from his brother. The direction of blood group transfer, from donor to recipient, was O Rh D+ to A Rh D+ in both cases. Approximately 12 days after transplantation, both recipients showed a rapid fall in their hemoglobin levels with no identifiable bleeding source. DAT positive hemolysis was confirmed and anti-A antibodies were detected in recipient sera, confirming a diagnosis of PLS. Both cases required blood transfusion support to maintain their hemoglobin and both had good renal outcomes. We have identified 99 PLS cases following renal transplant in the English literature. Previous ABO sensitization, donor blood group O to recipient blood group A or B transfer, and ciclosporin treatment have been identified as risk factors for PLS. Clinical outcomes in general are good; nonetheless, cases of graft failure and deaths have been reported. Early diagnosis and appropriate treatment are important in at risk individuals.

    The 2005 revised allocation scheme for pediatric renal transplantation made the decision of whether to transplant an available living-donor (LD) kidney or use a deceased-donor (DD) kidney controversial. The aim of this study was to examine kidney allograft utilization, sensitization, and outcomes of pediatric transplant recipients. Between January 2000 and December 2009, 91 consecutive pediatric kidney recipients (<20 yr) were transplanted. The LD (n = 38) and DD (n = 53) groups were similar in age, gender, dialysis status at transplant, warm ischemia time, and overall patient survival. LD recipients were more likely to be Caucasian (92 vs. 69%), receive older allografts (39 ± 10 vs. 23 ± 9 yr), and have fewer human leukocyte antigen (HLA) mismatches (3.3 ± 1.6 vs. 4.4 ± 1.5, p < 0.01 for all). Graft survival at one, three, and five yr post-transplant was longer for LD recipients (97%, 91%, 87% vs. DD 89%, 79%, 58%, respectively, p < 0.05). At the time of transplant, 17 (33%) DD recipients had an available LD (mean age 40 yr). A greater proportion of all patients were moderately (PRA 21-79%) sensitized post-transplant (p < 0.05). A multivariable analysis of graft survival indicated that the advantage in LD organs was likely due to fewer HLA mismatched in this group. Nonetheless, LD organs appear to provide optimal outcomes in pediatric renal transplants when considering the risk of becoming sensitized post-transplant complicating later use of the LD kidney.

    Objectives 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. Design A qualitative study using face-to-face in-depth semistructured interviews. Setting A UK tertiary renal referral hospital and transplant centre. Participants 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. Methods 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. Results 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. Conclusions 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

    It is unclear whether a concomitant kidney transplant grants survival benefit to liver transplant (LT) candidates with renal dysfunction (RD). We retrospectively studied LT candidates without RD (n = 714) and LT candidates with RD who underwent either liver transplant alone (RD-LTA; n = 103) or simultaneous liver–kidney transplant (RD-SLKT; n = 68). RD was defined as renal replacement therapy (RRT) requirement or modification of diet in renal disease (MDRD)-glomerular filtration rate (GFR) <25 mL/min/1.73 m2. RD-LTAs had worse one-yr post-transplant survival compared to RD-SLKTs (79.6% vs. 91.2%, p = 0.05). However, RD-LTA recipients more often had hepatitis C (60.2% vs. 41.2%, p = 0.004) and more severe liver disease (MELD 37.9 ± 8.1 vs. 32.7 ± 9.1, p = 0.0001). Twenty RD-LTA recipients died in the first post-transplant year. Evaluation of the cause and timing of death relative to native renal recovery revealed that only four RD-LTA recipients might have derived survival benefit from RD-SLKT. Overall, 87% of RD-LTA patients recovered renal function within one month of transplant. One yr after RD-LTA or RD-SLKT, serum creatinine (1.5 ± 1.2 mg/dL vs. 1.4 ± 0.5 mg/dL, p = 0.63) and prevalence of stage 4 or 5 chronic kidney disease (CKD; 5.9% vs. 6.8%, p = 0.11) were comparable. Our series provides little evidence that RD-SLKT would have yielded substantial short-term survival benefit to RD-LTA recipients. PMID:25328090

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

    PubMed

    Halimi, Jean-Michel

    2013-07-27

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

    A considerable percentage of patients exhibit anemia post kidney transplant. Its origin is multifactorial and the main causes involved depend on the post transplant period considered. We studied in a group of 134 consecutive patients the associated factors and the clinical implications of "late anemia" (6 months post transplant). Multiple regression analysis showed that post transplant oliguria and acute rejection episodes were significantly associated with anemia. Graft survival at 36 months was significantly reduced in the anemic group (83 % versus 96%, p < 0.01). No differences in patients survival or rate of cardiovascular events were observed. We concluded that anemia at 6 months post transplant is independently and significantly associated with events that reduced functioning renal mass and kidney survival.

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

    The safety and efficacy of tacrolimus in transplantation is well established. However, tacrolimus has only recently been available in India. We report an initial experience using tacrolimus as de novo therapy in a living related renal transplant program. Fifty-two consecutive recipients of living renal allografts were treated with tacrolimus, mycophenolate mofetil, or azathioprine and steroids. The dose of tacrolimus was adjusted to keep trough levels at 10 to 12 ng/mL in the first 3 months, 8 to 10 ng/mL in the next 3 months, and 5 to 8 ng/mL thereafter. Any evidence of graft dysfunction was evaluated by graft biopsy. The effect of this regimen on the lipid profile as well as the incidence of posttransplant diabetes mellitus was evaluated in an Indian population. All patients were followed for periods ranging from 6 to 72 weeks (mean = 29 weeks). The incidence of acute rejection was 3.84%; 17.3% developed posttransplant diabetes mellitus. Graft and patient survivals at the current follow-up were 100% and 96.26%. In conclusion, tacrolimus is a safe and effective immunosuppressant in a living related renal transplant program.

    Transplant renal artery stenosis (TRAS) is a well-recognized vascular complication after kidney transplant. It occurs most frequently in the first 6 months after kidney transplant, and is one of the major causes of graft loss and premature death in transplant recipients. Renal hypoperfusion occurring in TRAS results in activation of the renin-angiotensin-aldosterone system; patients usually present with worsening or refractory hypertension, fluid retention and often allograft dysfunction. Flash pulmonary edema can develop in patients with critical bilateral renal artery stenosis or renal artery stenosis in a solitary kidney, and this unique clinical entity has been named Pickering Syndrome. Prompt diagnosis and treatment of TRAS can prevent allograft damage and systemic sequelae. Duplex sonography is the most commonly used screening tool, whereas angiography provides the definitive diagnosis. Percutaneous transluminal angioplasty with stent placement can be performed during angiography if a lesion is identified, and it is generally the first-line therapy for TRAS. However, there is no randomized controlled trial examining the efficacy and safety of percutaneous transluminal angioplasty compared with medical therapy alone or surgical intervention.

    The comorbidity of psychological disorders with end-stage renal disease (ESRD) presents challenges for renal transplantation, including increased likelihood of medication noncompliance and poorer quality of life. Estimates of rates and severity of affective and anxiety disorders have varied significantly across studies of renal transplant patients, possibly due in part to variation in the methodology and timing of evaluations. To this point, few researchers have examined the psychological condition of patients who are newly referred for renal transplantation. This study examined rates of psychological distress using the Patient Health Questionnaire (PHQ) in a sample of 518 ESRD patients at the specific time point of first contact with the transplant center. In this sample, 15.1% of patients endorsed symptoms consistent with a depressive condition and 7.6% of patients endorsed an anxiety condition. These rates were lower than expected, which may be due to decreased distress in this sample, selection biases, or underreporting of symptoms due to patients' motivation to present themselves positively.

    Interstitial fibrosis and tubular atrophy (IF/TA) is a common cause of kidney allograft loss. Several noninvasive techniques developed to assess tissue fibrosis are widely used to examine the liver. However, relatively few studies have investigated the use of elastographic methods to assess transplanted kidneys. The aim of this study was to explore the clinical implications of the acoustic radiation force impulse (ARFI) technique in renal transplant patients. A total of 91 patients who underwent living donor renal transplantation between September 2010 and January 2013 were included in this prospective study. Shear wave velocity (SWV) was measured by ARFI at baseline and predetermined time points (1 week and 6 and 12 months after transplantation). Protocol biopsies were performed at 12 months. Instead of reflecting IF/TA, SWVs were found to be related to time elapsed after transplantation. Mean SWV increased continuously during the first postoperative year (P < 0.001). In addition, mixed model analysis showed no correlation existed between SWV and serum creatinine (r = -0.2426, P = 0.0771). There was also no evidence of a relationship between IF/TA and serum creatinine (odds ratio [OR] = 1.220, P = 0.7648). Furthermore, SWV temporal patterns were dependent on the kidney weight to body weight ratio (KW/BW). In patients with a KW/BW < 3.5 g/kg, mean SWV continuously increased for 12 months, whereas it decreased after 6 months in those with a KW/BW ≥ 3.5 g/kg.No significant correlation was observed between SWV and IF/TA or renal dysfunction. However, SWV was found to be related to the time after transplantation. Renal hemodynamics influenced by KW/BW might impact SWV values.

    Background Dysglycemia (encompassing impaired glucose tolerance and diabetes mellitus) arising after renal transplantation is common and confers a significant cardiovascular mortality risk. Nonetheless, the pathophysiology of posttransplant dysglycemia is not well described. The aim of this study was to prospectively and comprehensively assess glucose handling in renal transplant recipients from before to 12 months after transplantation to determine the underpinning pathophysiology. Materials and Methods Intravenous and oral glucose tolerance testing was conducted before and at 3 and 12 months posttransplantation. An intravenous glucose tolerance test was also performed on day 7 posttransplantation. We followed up 16 transplant recipients for 3 months and 14 recipients for 12 months. Insulin secretion, resistance and a disposition index (DI (IV)), a measure of β cell responsiveness in the context of prevailing insulin resistance, were also determined. Results At 12 months, 50% of renal transplant recipients had dysglycemia. Dysglycemia was associated with a dramatic fall in DI (IV) and this loss in β cell function was evident as early as 3 months posttransplantation (23.5 pretransplant; 6.4 at 3 months and 12.2 at 12 months posttransplant). Differences in the β cell response to oral glucose challenge were evident pretransplant in those destined to develop dysglycemia posttransplant (2-hour blood glucose level 5.6 mmol/L versus 6.8 mmol/L; P < 0.01). Conclusions Dysglycemia after renal transplantation is common, and the loss of insulin secretion is a major contributor. Subclinical differences in glucose handling are evident pretransplant in those destined to develop dysglycemia potentially heralding a susceptible β cell which under the stressors associated with transplantation fails.

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

    Autosomal dominant polycystic kidney disease (ADPKD) is the first genetic cause of end-stage renal disease (ESRD) and the number of these patients who are listed for or receive a kidney transplant (KTx) is continuously increasing over time. Hence, nephrologists are involved not only in the handling of ADPKD patients during the long course of the disease, but also in programming and performing a renal transplant. The handling of all these processes implies the complete awareness of a number of critical points related to the decisions to be taken both before and after the transplant intervention. In the present review, we will briefly deal with the main critical points related to the clinical handling of the patients both before and after KTx.

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

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

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

    Objective To compare long-term survival of living donor liver transplant (LDLT) at experienced transplant centers to outcomes of deceased donor liver transplant (DDLT) and identify key variables impacting patient and graft survival. Summary Background Data The Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) is a prospective multicenter NIH study comparing outcomes of LDLT and DDLT and associated risks. Methods Mortality and graft failure for 1427 liver recipients (963 LDLT) enrolled in A2ALL transplanted between 1/1/1998 and 1/31/2014 at 12 North American centers with median follow-up 6.7 years were analyzed using Kaplan-Meier and multivariable Cox models. Results Survival probability at 10 years was 70% for LDLT and 64% for DDLT. Unadjusted survival was higher with LDLT (HR=0.76, p=0.02) but attenuated after adjustment (HR=0.98, p=0.90) as LDLT recipients had lower mean MELD (15.5 vs 20.4) and fewer were transplanted from ICU, inpatient, on dialysis, ventilated, or with ascites. Post-transplant ICU days were less for LDLT. For all recipients female gender and primary sclerosing cholangitis were associated with improved survival, while dialysis and older recipient/donor age were associated with worse survival. Higher MELD score was associated with increased graft failure. Era of transplantation and type of donated lobe did not impact survival in LDLT. Conclusions LDLT provides significant long-term transplant benefit resulting in transplantation at a lower MELD score, decreased death on waitlist, and excellent post-transplant outcomes. Recipient diagnosis, disease severity, renal failure, and ages of recipient and donor should be considered in decision-making regarding timing of transplant and donor options.

    Children who receive a non-renal solid organ transplant may develop secondary renal failure requiring kidney transplantation. We investigated outcomes of 165 pediatric kidney transplant recipients who previously received a heart, lung, or liver transplant using data from 1988 to 2012 reported to the United Network for Organ Sharing. Patient and allograft survival were compared with 330 matched primary kidney transplant (PKT) recipients. Kidney transplantation after solid organ transplant (KASOT) recipients experienced similar allograft survival: 5- and 10-year graft survival was 78% and 60% in KASOT recipients, compared to 80% and 61% in PKT recipients (p = 0.69). However, KASOT recipients demonstrated worse 10-year patient survival (75% KASOT vs. 97% PKT, p < 0.001). Competing risks analysis indicated that KASOT recipients more often experienced graft loss due to patient death (p < 0.001), whereas allograft failure per se was more common in PKT recipients (p = 0.01). To study more recent outcomes, kidney transplants performed from 2006 to 2012 were separately investigated. Since 2006, KASOT and PKT recipients had similar 5-year graft survival (82% KASOT vs. 83% PKT, p = 0.48), although 5-year patient survival of KASOT recipients remained inferior (90% KASOT vs. 98% PKT, p < 0.001). We conclude that despite decreased patient survival, kidney allograft outcomes in pediatric KASOT recipients are comparable to those of PKT recipients.

    Renal osteodystrophy may persist during the early years after renal transplantation. However, information on bone status after a successful long-term renal transplantation is limited. We examined biochemical parameters, bone mineral density (BMD), and bone histomorphometry in 25 asymptomatic men with normal renal function after 7.5 +/- 5.7 years of a renal transplantation. Serum calcium, phosphorus, alkaline phosphatase, and 1,25(OH)(2)D(3) levels and urinary calcium level and cyclic andenosine monophosphate excretion were within normal range in all patients. Serum intact parathyroid hormone (PTH) level was elevated in 11 subjects (133.6 +/- 78 pg/mL) and normal in the other 14 subjects (47.9 +/- 13.6 pg/mL). Mean BMD at the lumbar spine and femoral neck was low in the entire group. However, it progressively increased as time after transplantation increased, approaching normal values after 10 years. Bone histomorphometric analysis showed bone resorption, osteoid volume, and osteoid surface greater than normal range in the majority of patients. Bone formation rate and mineralization surface were low, and mineralization time was delayed in most patients. These lesions were more severe in patients after 3 to 4 years of transplantation but improved with time and approached normal values after a period of 10 years. PTH values did not correlate with bone histological characteristics or BMD. These results show that the bone alterations observed after long-term renal transplantation consist of a mixed bone disease in which features of high bone turnover coexist with altered bone formation and delayed mineralization. These findings may result from the combined effect of preexisting bone disease and immunosuppressive therapy.

    We present a case in which a deceased donor kidney with a large simple cyst was successfully unroofed and transplanted to a 61-year-old male. The donor was a 62-year-old male with a history of hypertension for 2 years; cerebral vascular accident was the cause of death. A large 8-cm cyst distorting the renal hilum was identified upon the procurement of the deceased donor kidney. Prior to transplantation, the large cyst was unroofed from the allograft; the frozen section confirmed a benign cyst and the transplant was performed. Postoperatively, the serum creatinine level was 1.4 mg/ml at 22-month follow-up and the patient was normotensive. Deceased donor kidneys with giant cysts distorting the renal hilum can be effectively transplanted. PMID:24049388

    We previously described early results of a non-chimeric operational tolerance protocol in HLA identical living donor renal transplants and now update these results. Recipients given alemtuzumab, tacrolimus/MPA with early sirolimus conversion were multiply infused with donor hematopoietic CD34+ stem cells. Immunosuppression was withdrawn by 24 months. Twelve months later operational tolerance was confirmed by rejection-free transplant biopsies. Five of the first 8 enrollees were initially tolerant one year off immunosuppression. Biopsies of 3 others after total withdrawal showed Banff 1A acute cellular rejection without renal dysfunction. With longer follow-up including 5 year post-transplant biopsies 4 of the 5 tolerant recipients remain without rejection while one developed Banff 1A without renal dysfunction. We now add 7 new subjects (2 operationally tolerant), and demonstrate time-dependent increases of circulating CD4+CD25+++CD127−FOXP3+ Tregs vs. losses of Tregs in non-tolerant subjects (p< 0.001). Gene expression signatures, developed using global RNA expression profiling of sequential whole blood and protocol biopsy samples, were highly associative with operational tolerance as early as 1 year post-transplant. The blood signature was validated by an external ITN data set. Our approach to non-chimeric operational HLA identical tolerance reveals association with Treg immunophenotypes and serial gene expression profiles. PMID:26227106

    Viruses are among the most common causes of opportunistic infection after transplantation. The risk for viral infection is a function of the specific virus encountered, the intensity of immune suppression used to prevent graft rejection, and other host factors governing susceptibility. Although cytomegalovirus is the most common opportunistic pathogen seen in transplant recipients, numerous other viruses have also affected outcomes. In some cases, preventive measures such as pretransplant screening, prophylactic antiviral therapy, or posttransplant viral monitoring may limit the impact of these infections. Recent advances in laboratory monitoring and antiviral therapy have improved outcomes. Studies of viral latency, reactivation, and the cellular effects of viral infection will provide clues for future strategies in prevention and treatment of viral infections. This paper will summarize the major viral infections seen following transplant and discuss strategies for prevention and management of these potential pathogens. PMID:22654630

    Histopathology is still an indispensable tool for the diagnosis of kidney transplant dysfunction in adult and pediatric patients. This review presents consolidated knowledge, recent developments and future prospects on the biopsy procedure, the diagnostic work-up, classification schemes, the histopathology of rejection, including antibody-mediated forms, ABO-incompatible transplants, protocol biopsies, recurrent and de novo disease, post-transplant lymphoproliferative disorder, infectious complications and drug-induced toxicity. It is acknowledged that frequently the correct diagnosis can only be reached in consensus with clinical, serological, immunogenetical, bacteriological and virological findings. This review shall enhance the understanding of the pediatric nephrologist for the thought processes of nephropathologists with the aim to facilitate teamwork between these specialist groups for the benefit of the patient.

    Kidney transplant recipients frequently suffer from skin infections and malignancies, possibly due to the effects of long-term immunosuppressive therapy. While the relationships between immunosuppression and these pathological conditions have been widely investigated, little is known about the relative incidence and characteristics of inflammatory skin diseases in this type of patient. In this study, we analyze the incidence of a number of inflammatory cutaneous diseases in a cohort of patients who underwent kidney transplantation. Although our study shows a relatively low incidence of these pathologies in transplanted patients—in agreement with the general action of immunosuppressant therapies in reducing inflammation—we scored a different efficacy of the various immunosuppressive regimens on inflammatory and autoimmune skin diseases. This information can be key for designing immunosuppressive regimens and devising accurate follow-up protocols. PMID:27548160

    A prospective evaluation of In-111 labeled autologous platelet scintigraphy for the early diagnosis of acute postoperative renal transplant rejection was undertaken. To date, 28 consecutive patients between 7 and 14 days post-op have been injected with 500..mu..Ci of In-111 platelets followed by imaging at 24 and 48 hours. Activity within the renal transplant exceeding activity in the adjacent iliac vessels was considered to be evidence of rejection, and both chemical evidence and clinical impression of rejection at 5 days after completion of imaging was accepted as proof of ongoing or incipient rejection at the time of scintigraphy. In addition, to visual inspection, independent quantitative analysis compared the area-normalized activity over the transplant with the adjacent iliac vessels (normal <1.0). For 5 patients, positive In-111 scintigraphy was present before convincing clinical evidence of rejection. In-111 platelet scintigraphy is useful not only to confirm the clinical diagnosis of rejection but also to establish the early, pre-clinical diagnosis of incipient acute postoperative renal transplant rejection.

    Chronic allograft injury (CAI) limits the long-term success of renal transplantation. Nestin is a marker of progenitor cells, which probably contribute to its pathogenesis. We hypothesize that nestin is induced by ischemia/reperfusion injury and acute rejection, main risk factors for CAI. Syngeneic renal transplantation was performed in Lewis rats and allogeneic transplantation in the Fischer 344 to Lewis strain combination, which results in reversible acute rejection and in CAI in the long-run. The Dark Agouti to Lewis rat strain combination was used to study fatal acute rejection. In untreated kidneys, nestin immunoreactivity was detected in glomeruli and in very few interstitial or microvascular cells. Syngeneic transplantation induced nestin expression within 4 days, which decreased until day 9 and returned to control levels on day 42. Nestin expression was strong during acute rejection and still detected during the pathogenesis of CAI on day 42. Nestin-positive cells were identified as endothelial cells and interstitial fibroblast-like cells co-expressing alpha-smooth muscle actin. A sub-population of them expressed proliferating cell nuclear antigen. In conclusion, nestin is induced in renal grafts by ischemia/reperfusion injury and acute rejection. It is expressed by proliferating myofibroblasts and endothelial cells and probably contributes to the pathogenesis of CAI.

    The disparity between the number of patients waiting for kidney transplantation and the limited supply of kidney allografts has renewed interest in the benefit from kidney transplantation experienced by different groups. This study evaluated kidney transplant survival benefit in prior non-renal transplant recipients (kidney after liver, KALi; lung, KALu; heart, KAH) compared to primary isolated (KA1) or repeat isolated kidney (KA2) transplant. Multivariable Cox regression models were fit using UNOS data for patients wait listed and transplanted from 1995–2008. Compared to KA1, the risk of death on the wait list was lower for KA2 (p<0.001;HR=0.84;CI=0.81–0.88), but substantially higher for KALu (p<0.001;HR=3.80;CI=3.08–4.69), KAH (p<0.001;HR=1.92;CI=1.66–2.22), and KALi (p<0.001;HR=2.69;CI=2.46–2.95). Following kidney transplant, patient survival was greatest for KA1, similar among KA2, KALi, KAH, and inferior for KALu. Compared to the entire wait list, renal transplantation was associated with a survival benefit among all groups except KALu (p=0.017;HR=1.61;CI=1.09–2.38), where post-transplant survival was inferior to the wait list population. Recipients of KA1 kidney transplantation have the greatest post-transplant survival and compared to the overall kidney wait list, the greatest survival benefit. PMID:20977641

    The synthesis and whole body metabolism of L-arginine (Arg) are disturbed in renal diseases. Renal transplantation represents the best therapy in the end-stage of these diseases. In the present we compared alterations of plasma Arg and related compounds with renal excretory function in patients with end-stage renal disease, before and after kidney transplantation. Arg, asymmetric dimethylarginine (ADMA), citrulline (Cit), glutamine (Gln), ornithine (Orn), phenylalanine (Phe), tyrosine (Tyr), urea, creatinine, albumin, and nitrate were analyzed in patients before, immediately after (0-time) and 1, 2, 3, 7 and 14 days following living donors kidney transplantation. Healthy subjects were controls. Glomerular filtration rate (GFR) and amino acid molar ratios were calculated. Before transplantation creatinine, urea, Cit, Gln, ADMA, and nitrate were above, while GFR and Arg were below controls, confirming disturbed excretory and metabolic renal functions in patients with renal disease. Renal transplantation promptly normalized creatinine, urea, GFR, Cit, and nitrate. However, regardless of increased molar Phe/Tyr ratios, indicating increased net protein catabolism in peripheral tissues, low Arg and elevated ADMA concentrations persisted throughout the examined period. Alterations of other amino acids also suggest similarly disturbed Arg metabolism in patients after kidney transplantation. In conclusion, renal transplant promptly restored its excretory function, but increased net protein catabolism, disturbed Arg metabolism and endothelial dysfunction in entire body of these patients were not improved throughout the early period after the operation. That has to be considered in their therapy.

    Experimentally, females show an improved ability to recover from ischemia-reperfusion injury (IRI) compared with males; however, this sex-dependent response is less established in humans. Here, we developed a series of murine renal ischemia and transplant models to investigate sex-specific effects on recovery after IRI. We found that IRI tolerance is profoundly increased in female mice compared with that observed in male mice and discovered an intermediate phenotype after neutering of either sex. Transplantation of adult kidneys from either sex into a recipient of the opposite sex followed by ischemia at a remote time resulted in ischemia recovery that reflected the sex of the recipient, not the donor, revealing that the host sex determines recovery. Likewise, renal IRI was exacerbated in female estrogen receptor α–KO mice, while female mice receiving supplemental estrogen before ischemia were protected. We examined data from the United Network for Organ Sharing (UNOS) to determine whether there is an association between sex and delayed graft function (DGF) in patients who received deceased donor renal transplants. A multivariable logistic regression analysis determined that there was a greater association with DGF in male recipients than in female recipients. Together, our results demonstrate that sex affects renal IRI tolerance in mice and humans and indicate that estrogen administration has potential as a therapeutic intervention to clinically improve ischemia tolerance.

    Guatemala is Central America's westernmost country, with a ratio of 500,000 inhabitants per nephrologist. Yearly reports show an average of 150 new end-stage renal disease patients and 40 renal transplants, which are performed at two public health care facilities. The aim of this study was to describe the results of the transplant program at one of these centers (Social Security Hospital of Guatemala). Our program began in 1986, performing an average of 17 transplants per year. Cyclosporine has been used since 1992, and since 2001, C2 has been routinely monitored. Data on 255 patients (of 293) were available for analysis. Male-to-female ratio was 7:1, with 94% having received hemodialysis as their replacement therapy. The mean age at transplant was 35 years and living related donors used in 95%. The average duration of follow-up was 7 years. The mean creatinine and C2 level at most recent visit were 1.36 mg/dL and 864 ng/mL, respectively. A significant reduction in the incidence of acute rejection episodes was seen after the initiation of C2 monitoring (3% vs 1.2%). In general, these results are similar to data in other countries. The number of transplants performed must be increased to meet the current demand, and the cadaveric source of donation is the obvious way to do so. C2 monitoring is an example of technical improvements directed to optimize available resources.

    The frequency of histoplasmosis among solid organ transplant (SOT) recipients appears to be low where there are only a few case series, mostly among renal and liver transplant recipients. Herein we report a case of a 44-year-old woman who underwent a living-related renal transplant 18 years prior to evaluation, developed a nodule after followed by ulceration upon her posterior right leg and a second one upon her left leg 3 months and 2 months before her hospitalisation, respectively. The biopsy of lesion revealed the presence of Histoplasma spp. Bone marrow aspiration was performed and also revealed the same organism. She had initially received itraconazole without improvement of lesions, while a new lesion appeared on her left arm. Healing of all lesions could be observed after 40 days of liposomal amphotericin B when she was submitted to skin grafts on the legs and a surgical treatment on the arms, and the myelosuppression improved simultaneously. Histoplasmosis seems to be very uncommon among patients who underwent to organ solid transplantation. Most cases occur within 12-18 months after transplantation, although unusual cases have been presented many years post-transplant. There are cases reported in the literature, occurring from 84 days to 18 years after organ transplantation, but without cutaneous involvement. Our patient developed lesions on limbs and myelosuppression after 18 years of chronic immunosuppression medication. This case suggests that besides cutaneous histoplasmosis is an uncommon infection following iatrogenic immunosuppression and even rarer over a long period after the transplantation. Clinicians who care SOT recipient patients must bear in mind histoplasmosis infection as differential diagnosis in any case of cutaneous injury with prolonged fever and try to use as many tools as possible to make the diagnosis, once this disease presents a good prognosis if it is diagnosed and treated promptly.

    Introduction Urinary tract infection (UTI), especially recurrent UTI, is a common problem, occurring in >75% of kidney transplant (KTX) recipients. UTI degrades the health-related quality of life and can impair graft function, potentially reducing graft and patient survival. As urologists are often involved in treating UTI after KTX, previous reports were searched to elucidate underlying causes, risk factors and treatment options, as well as recommendations for prophylaxis of UTI after KTX. Methods Pubmed/Medline was searched and international guidelines and recommendations for prevention and treatment of UTI after KTX were also assessed. Results Most studies on UTI after KTX have a small sample, and are descriptive and retrospective. Many transplant- and recipient-related risk factors have been identified. While asymptomatic bacteriuria is often treated, even though some studies advise against it, symptomatic UTI should be treated empirically after collecting urine for microbiological analysis, to avoid the development of transplant pyelonephritis with a high chance of urosepsis. The duration of treatment has not been determined in studies and recommendations refer to the treatment of complicated UTI in the non-transplant population. Prophylaxis has not been the focus of studies either. Conclusion UTI after KTX is still largely an under-represented field of study, despite many recipients developing UTI after KTX. Prospective studies on this topic are urgently needed. PMID:26558020

    2016-01-01

    Kidney transplantation is recognised as the most effective treatment for patients with end-stage renal disease (ESRD). Kidney transplantation continues to face several challenges including long-term graft and patient survival, and the side effects of immunosuppressive therapy. The tendency in kidney transplantation is to avoid the side effects of immunosuppresants and induce immune tolerance. Regulatory T-cells (Tregs) contribute to self-tolerance, tolerance to alloantigen and transplant tolerance, mainly by suppressing the activation and function of reactive effector T-cells. Additionally, Tregs are implicated in the pathogenesis of diabetes, which is the leading cause of ESRD, suggesting that these cells play a role both in the pathogenesis of chronic kidney disease and the induction of transplant tolerance. Several strategies to achieve immunological tolerance to grafts have been tested experimentally, and include combinations of co-stimulatory blockade pathways, T-cell depletion, in vivo Treg-induction and/or infusion of ex-vivo expanded Tregs. However, a successful regimen that induces transplant tolerance is not yet available for clinical application. This review brings together certain key studies on the role of Tregs in ESRD, diabetes and kidney transplantation, only to emphasize that many more studies are needed to elucidate the clinical significance and the therapeutic applications of Tregs.

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

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

    AIM To explore the benefits and harms of corticosteroid (CS) minimization following renal transplantation. METHODS CS minimization attempts to improve cardiovascular risk factors (hypertension, diabetes, dyslipidemia), to enhance growth in children, to ameliorate bone disease and to lead to better compliance with immunosuppressive agents. Nevertheless, any benefit must be carefully weighed against the reduction in net immunosuppression and the potential harm to renal allograft function and survival. RESULTS Complete CS avoidance or very early withdrawal (i.e., no CS after post-transplant day 7) seems to be associated with better outcomes in comparison with later withdrawal. However, an increased incidence of CS-sensitive acute rejection has been observed with all CS minimization strategies. Among the prerequisites for the safe application of CS minimization protocols are the administration of induction immunosuppression and the inclusion of calcineurin inhibitors in maintenance immunosuppression regimens. CONCLUSION Transplant recipients at low immunological risk (primary transplant, low panel reactive antibodies) are thought as optimal candidates for CS minimization. CS avoidance may also be undesirable in patients at risk for glomerulonephritis recurrence or with severe delayed graft function and prolonged cold ischemia time. Thus, CS minimization is not yet ready for implementation in the majority of transplant recipients. PMID:28058228

    Arterial hypertension often present after kidney transplantation is of multifactorial origin. The aim of this study was to determine the role of donor and recipient factors in the development of hypertension after renal transplantation. We retrospectively analyzed the data of 280 patients transplanted between 1985 and 2005, who still had functioning grafts at 1 year after transplantation. We recorded donor and recipient parameters. One hundred eighty-seven patients (66.8%) were hypertensive. Upon multivariate analysis of recipient factors, pretransplant hypertension (odds ratio) [OR]: 8.5, 95% confidence interval [CI]: 4.5 to 16.1); serum creatinine level > 130 micromol/L at 6 months (OR: 2.5, 95% CI: 1.3 to 4,7), male gender (OR: 2.02, 95% CI: 1.2 to 3.4), and chronic rejection (OR: 2.4, 95% CI: 1.2 to 4.7) were independent predisposing factors. Among donor factors, age was significantly associated with arterial hypertension upon univariate analysis. In conclusion, recipient factors, especially pretransplant hypertension, contribute to the disorder in renal transplant patients.

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

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

    Background and objectives: Kidney transplantation is the most desired and cost-effective modality of renal replacement therapy for patients with irreversible chronic kidney failure (end-stage renal disease, stage 5 chronic kidney disease). Despite emerging evidence that the best outcomes accrue to patients who receive a transplant early in the course of renal replacement therapy, only 2.5% of incident patients with end-stage renal disease undergo transplantation as their initial modality of treatment, a figure largely unchanged for at least a decade. Design, setting, participants, & measurements: The National Kidney Foundation convened a Kidney Disease Outcomes Quality Initiative (KDOQI) conference in Washington, DC, March 19 through 20, 2007, to examine the issue. Fifty-two participants representing transplant centers, dialysis providers, and payers were divided into three work groups to address the impact of early transplantation on the chronic kidney disease paradigm, educational needs of patients and professionals, and finances of renal replacement therapy. Results: Participants explored the benefits of early transplantation on costs and outcomes, identified current barriers (at multiple levels) that impede access to early transplantation, and recommended specific interventions to overcome those barriers. Conclusions: With implementation of early education, referral to a transplant center coincident with creation of vascular access, timely transplant evaluation, and identification of potential living donors, early transplantation can be an option for substantially more patients with chronic kidney disease.

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

    Background Transplant centers vary in the proportion of kidney transplants performed using live donors. Clinical innovations that facilitate live donation may drive this variation. Methods We assembled a cohort of renal transplant candidates at 194 US centers using registry data from 1999 – 2005. We measured magnitude of live donor transplant (LDKTx) through development of a standardized live donor transplant ratio (SLDTR) at each center that accounted for center population differences. We examined associations between center characteristics and the likelihood that individual transplant candidates underwent LDKTx. To identify practices through which centers increase LDKTx, we also examined center characteristics associated with consistently being in the upper three quartiles of SLDTR. Results The cohort comprised 148,168 patients, among whom 34,593 (23.3%) underwent LDKTx. In multivariable logistic regression, candidates had an increased likelihood of undergoing LDKTx at centers with greater use of “unrelated donors” (defined as non-spouses and non-first-degree family members of the recipient; OR 1.31 for highest versus lowest use, p=0.02) and at centers with programs to overcome donor-recipient incompatibility (OR 1.33, p=0.01.) Centers consistently in the upper three SLDTR quartiles were also more likely to use “unrelated” donors (OR 8.30 per tertile of higher use, p<0.01), to have incompatibility programs (OR 4.79, p<0.01), and to use laparoscopic nephrectomy (OR 2.53 per tertile of higher use, p=0.02). Conclusion Differences in center population do not fully account for differences in the use of LDKTx. To maximize opportunities for LDKTx, centers may accept more unrelated donors and adopt programs to overcome biological incompatibility. PMID:21562451

    Summary Background and objectives Non-renal transplant recipients who subsequently develop ESRD and undergo kidney transplantation are medically and immunologically complex due to comorbidities, high cumulative exposure to immunosuppressants, and sensitization to alloantigen from the prior transplant. Although prior non-renal transplant recipients are one of the fastest growing segments of the kidney wait list, minimal data exist to guide the use of antibody induction therapy (IT+) at the time of kidney after lung (KALu), heart (KAH), and liver (KALi) transplant. Design, setting, participants, & measurements This retrospective cohort study used national registry data to examine IT use and survival after kidney transplantation. Separate multivariate Cox regression models were constructed to assess patient survival for IT+ and IT− KALu (n=232), KAH (n=588), and KALi (n=736) recipients. Results Use of IT increased during the study period. The percentage of patients considered highly sensitized (panel reactive antibody ≥20%) was not statistically significant between IT+ and IT− groups. IT+ was not associated with improvement in 1- and 10-year patient survival for KALu (P=0.20 and P=0.22, respectively) or for KAH (P=0.90 and P=0.14, respectively). However, IT+ among KALi was associated with inferior patient survival at 1 and 10 years (P=0.04 and P=0.02, respectively). Conclusions Use of IT for kidney transplantation among prior non-renal transplant recipients may not offer a survival advantage in KALu or KAH. However, due to limited power, these findings should be interpreted cautiously. IT+ was associated with inferior outcomes for KALi. Use of IT should be judicially reconsidered in this complex group of recipients. PMID:22076872

    Neurological complications post transplant have been described with the use of calcineurin inhibitors. Although tacrolimus may be a better immunosuppressant than cyclosporine, its neurological side effects may be worse. Two children, living-related kidney transplant recipients, were treated with antibody induction, mycophenolate mofetil, prednisone, and tacrolimus. Soon after transplant, they each developed an encephalopathy, which when visualized by magnetic resonance imaging showed that it affected both white and grey matter of the brain. Although the encephalopathy was associated with the use of tacrolimus, there was a complete neurological recovery without cessation of the drug.

    Renal transplantation is the treatment of choice for children with ESRD offering advantages of improved survival, growth potential, cognitive development, and quality of life. The aim of our study was to compare the outcomes of LDKT vs DDKT performed in children at a single center. Retrospective chart review of pediatric patients who underwent kidney transplantation from 2005 to 2014 was performed. Ninety-one renal transplants were accomplished, and 31 cases (38.27%) were LDKT, and in 96.7% of the cases, the graft was obtained through laparoscopy. Thirty-four receptors weighted <25 kg. LDKT group had statistically significant lower cold ischemia times than DDKT one. Complication rate was 9.67% for LDKT and 18.33% for DDKT. eGFR was better in LDKT. Patient survival rate was 100% for LDKT and 98.3% for DDKT, and graft survival rate was 96.7% for LDKT and 88.33%-80% for DDKT at a year and 5 years. Our program of pediatric kidney transplantation has achieved optimal patient and graft survival rates with low rate of complications. Living donor pediatric kidney transplants have higher patient and better graft survival rates than deceased donor kidney transplants.

    Scrub typhus is a rickettsial infection commonly seen in Asia. The clinical presentation ranges from nonspecific febrile illness to potentially fatal multiorgan involvement such as liver, kidney, or lung. Central nervous system involvement is uncommon. We report a 45-year-old female renal transplant recipient who presented with fever, headache, meningeal signs, graft dysfunction, and eschar. IgM antibodies against Orientia tsutsugamushi were positive by enzyme-linked immunosorbent assay. Despite oral doxycycline therapy for 5 days, she did not improve but responded well to intravenous azithromycin. To the best of our knowledge, scrub typhus as a cause of meningitis in a renal transplant recipient has not been reported so far. PMID:28356672

    This cross-sectional study evaluated the prevalence of major depressive disorder and depressive symptoms in children and adolescents after renal transplantation. A total of 71 patients who had undergone renal transplantation were interviewed in person using the Farsi (Persian) version of the Kiddie Schedule for Affective Disorders and Schizophrenia and Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria. Major depressive disorder, depressive symptoms, and suicidal behaviors were assessed. The rate of major depressive disorder was 2.8%; two-thirds of the patients had irritability; and approximately 40% had recurrent thoughts of death and suicidal ideation. The rate of major depressive disorder was lower than in other chronic diseases such as thallasemia or hemophilia; however, the rate of suicidal behaviors was high.

    Female kidneys and kidneys from small donors have been suggested to perform worse after kidney transplantation. Here, we evaluate the impact of gender and body dimensions on posttransplantation GFR in living donor transplantation. Two hundred and ninety-three donor-recipient pairs, who were transplanted at our center were evaluated. All pairs had detailed renal function measurement ((125) I-iothalamate and (131) I-hippuran) 4 months predonation in the donor and 2.5 months posttransplantation in donor and recipient. For 88 pairs, 5 years of recipient follow-up was available. Delta GFR was calculated as (recipient GFR-donor single kidney GFR). Recipients of both male and female kidneys had similar renal function at early and long term after transplantation. Male recipients had higher ERPF, ΔGFR and ΔERPF at both time points. Kidneys of donors smaller than their recipient had higher ΔGFR and ΔERPF than kidneys of larger donors at both time points (p < 0.05). In multivariate analysis, ΔGFR was predicted by donor/recipient BSA-ratio together with transplantation related factors (R(2) 0.19), irrespective of donor and recipient gender. In conclusion, in living donor transplantation, female kidneys perform as well as male donor kidneys. Kidneys adapt to the recipient's body size and demands, independent of gender, without detrimental effects in renal function and outcome up to mid-long term.

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

    This review examines a 20-year experience in renal transplantation at our center to determine the effects of immunosuppression on the subsequent development of malignancies. Twenty patients had 21 malignancies from primary sites other than skin, yielding an incidence of 2.5%. There were 0.65 malignancies for each 100 cumulative patient years of immunosuppression. Suppression of the host immune response is associated with an increased incidence of malignancies.

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

    Recent studies demonstrate that the human microbiota, the collection of microorganisms growing on and in individuals, have numerous bidirectional interactions with the host, influencing immunity, resistance to infection, inflammation and metabolism. Little has been done to study the potential associations between microbiota composition and transplant outcome. Here, we investigated the longitudinal changes in the blood, urinary, oral and rectal microbiota of renal allograft recipients before and at 1 and 6 months after transplantation. The results showed major changes in microbiota composition as a result of the transplant episode and associated medications, and these changes persisted over time. The high interindividual variation as well as differences in response to transplantation suggested that it is unlikely that the same specific microbiota members can serve as universal diagnostic markers. Rather, longitudinal changes in each individual's microbiota have the potential to be indicative of health or disease. Use of sensitive nucleic acid-based testing showed that urine, irrespective of disease states, more often harbors a diverse microbiota than appreciated by conventional culture techniques. These results lay the groundwork to construct more comprehensive future investigations to identify microbiota characteristics that can serve as diagnostic markers for transplant health and to guide intervention strategies to improve transplant outcome.

    The aim of this prospective study was to investigate the rate of BK (BKPyV) and JC (JCPyV) polyomavirus infections and their influence on allograft function in Tunisian renal transplant recipients. A total of 72 renal transplant recipients were studied. BKPyV and JCPyV were detected and quantified by real-time PCR in urine and plasma. Demographic and laboratory characteristics were collected for each patient. Polyomavirus DNAuria was detected in 54 (75%) of renal transplant recipients: 26 (36%) had BKPyV DNAuria, 20 (28%) had JCPyV DNAuria, and 8 (11%) had a dual BKPyV/JCPyV DNAuria. BKPyV DNAemia was detected in four (5.5%) patients, whereas no patient had JCPyV viremia. More than 70% of BKPyV and JCPyV infections started within the first 3 months post-transplant. The risk for positive DNAemia was observed in patients with DNAuria level >10(7) copies/ml. BK Polyomavirus-associated nephropathy (BKPyVAN) was observed in two patients. This study highlights the high frequency of BKPyV and JCPyV viruria during the first year post-transplant with the highest incidence observed in the third month. We identified several risk factors that were associated with BKV DNAuria including age, sex of patients, and the use of tacrolimus instead of cyclosporine A at month 3. The use of cyclosporine A instead of tacrolimus was identified as risk factor for JCV viruria in month 3. No statistical difference in the allograft function was found between BKPyV and/or JCPyV infected and uninfected patients.

    Renal transplantation is associated with increased incidence of cancer. We reviewed a large series of renal transplant recipients to determine the incidence and outcome of patients with malignant changes located at the head and neck. A total of 1232 renal transplant recipients have been followed at Department of Dialysis University Hospital Centre Zagreb from 1972 to 2009. Demographic data, localization and disease outcome were evaluated in patients who developed cancer. Twenty one patients (1.7%) developed 27 head and neck malignancies. The average time from transplantation to development of cancer was 56.8 months. The mean length of follow-up was 9.4+/-4.8 years. Eighteen malignancies were cutaneous in origin and 9 were noncutaneous. Of cutaneous malignancies, 88.9% were basal cell carcinoma; one patient had Merkell-cell carcinoma and one patient developed squamous cell carcinoma. Six cases of basocellular skin cancer were recorded in one fair-skin patient. Noncutaneous malignancies involved the oral cavity (2 cases of Kaposi's sarcoma and one pharyngeal cancer) and the thyroid gland in 3 patients each. Two patients had post-transplant lymphoproliferative disorder occurring at the head and neck. One patient had brain tumor. Radical surgery, radiation, and/or chemotherapy were necessary in 33.3% of patients. Immunosuppression was reduced in all patients, and 12 patients were switched from the calcineurin-based immunosuppression to sirolimus. They all have stable graft function. None of the patients died from cancer. Immunosuppression was ceased in one patient with Kaposi's sarcoma who returned to dialysis and died 10 years later from heart failure. An increased incidence of cancer occurring in the head and neck was recorded. Careful skin examination and oral examination is mandatory for discovering cancer before dissemination. Sirolimus is safe alternative to calcineurin-based immunosuppression in patients who developed head and neck malignancies.

    Hepatocellular injury in renal transplant recipients with hepatitis C virus (HCV) infection remains unclear. The suppressed immune response, in combination with increased viremia levels, provides a unique setting for the study of a potential HCV-induced apoptotic process. Liver biopsy specimens from 59 HCV-infected renal transplant recipients were examined histologically. DNA fragmentation was detected by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-nick end labeling assay, and the CD8 T-cell count was assessed immunohistochemically.A low apoptotic index (0-2.5) was observed in 31 cases, a moderate index (2.6-5) in 16, and a high index (>5) in 12. Apoptotic cell death correlated significantly with viremia because it was demonstrated by higher HCV-RNA levels in cases with a high number of apoptotic cells (odds ratio, 2.96; 95% confidence interval, 1.0-8.5; P = .04). No correlation was found between the apoptotic index and hepatitis necroinflammatory activity, CD8 cell count, fibrosis stage, immunosuppressive therapy, or genotype. In HCV-infected renal transplant recipients, apoptotic cell death seems to be associated with high viral load, thus providing indications of viral interference in the pathogenetic process.

  1. Platelets in Early Antibody-Mediated Rejection of Renal Transplants

    Antibody-mediated rejection is a major complication in renal transplantation. The pathologic manifestations of acute antibody-mediated rejection that has progressed to functional impairment of a renal transplant have been defined in clinical biopsy specimens. However, the initial stages of the process are difficult to resolve with the unavoidable variables of clinical studies. We devised a model of renal transplantation to elucidate the initial stages of humoral rejection. Kidneys were orthotopically allografted to immunodeficient mice. After perioperative inflammation subsided, donor-specific alloantibodies were passively transferred to the recipient. Within 1 hour after a single transfer of antibodies, C4d was deposited diffusely on capillaries, and von Willebrand factor released from endothelial cells coated intravascular platelet aggregates. Platelet-transported inflammatory mediators platelet factor 4 and serotonin accumulated in the graft at 100- to 1000-fold higher concentrations compared with other platelet-transported chemokines. Activated platelets that expressed P-selectin attached to vascular endothelium and macrophages. These intragraft inflammatory changes were accompanied by evidence of acute endothelial injury. Repeated transfers of alloantibodies over 1 week sustained high levels of platelet factor 4 and serotonin. Platelet depletion decreased platelet mediators and altered the accumulation of macrophages. These data indicate that platelets augment early inflammation in response to donor-specific antibodies and that platelet-derived mediators may be markers of evolving alloantibody responses.

    What we accomplish today as a matter of routine was only imagined by a few 4 decades ago. The journey from that first successful kidney transplant in the 1950s to the multidisciplinary, multiorgan transplant program of today has been a fascinating one. Although we attribute our current results to careful recipient selection and preparation, improvements in organ procurement and preservation, refinement of surgical techniques, improvement in histocompatibility techniques and organ sharing, improvements in immunosuppression and infection control, and careful monitoring of recipients, we and our patients have benefited from significant contributions from our colleagues in government and the law. The 4 that come to mind are the provision of near-universal insurance coverage for end stage renal disease patients in 1972 under the Medicare program, the passage of brain death laws in the mid 1970s, the passage of the National Transplant Act in 1984, and the passage of the Oregon required request law in 1985.

    Thrombophilia due to activated protein C resistance (Leiden mutation) is the most common inherited thrombophilic disorder with 5% incidence in whites. Renal transplant of these patients entails a risk of vascular thrombosis soon after the transplant; and acute rejection episodes and graft loss within the first year. We present a case of a successful living-related renal transplant in man with a recent history of repeat episodes of vascular access thrombosis attributed to inherited thrombophilia (heterozygosity for factor V mutation Q506 and homozygosity for mutation T677 for methylene-tetrahydrofolate reductase). Transplant recipient was administered anticoagulation therapy with low molecular weight heparin pre- and postoperatively. No thrombotic or hemorrhagic events occurred posttransplant. A high suspicion of thrombophilic disorders in patients with end-stage renal disease with vascular access thrombotic events should be screened further to prevent failure of a subsequent renal transplant. Inherited thrombophilic disorders may not exclude living-related kidney transplant provided that anticoagulation therapy is admin-istered perioperatively.

  4. Urolithiasis in renal transplant donors and recipients: An update.

    Urolithiasis in the context of renal transplant is a quite rare event that requires keeping a higher index of suspicion and vigilance. Donors with incidentally discovered asymptomatic renal stones "donor gifted lithiasis" are potentially considered for donation should they are not recurrent stone formers and in the absence of active biochemical disorders. Stone clearance from the donors can be done before donation using shock wave lithotripsy and/or flexible ureteroscopy. Ex vivo ureteroscopy at time of transplant is equally feasible and safe. A variety of anatomical, metabolic and surgical factors contribute to de novo lithiasis after transplantation. Diagnosis is challenging as the transplanted kidney is denervated and the presentation is consequently, atypical. Endourological armamentarium is readily present within the hands of the urologists for adequately addressing the stones and including shock wave lithotripsy, percutaneous nephrolithotomy and flexible ureteroscopy. Whilst all endourological techniques have proven feasibility and safety, they are surgically demanding and requiring high-volume expertise to be adequately performed. The longterm outcome in terms of stone recurrence or the effect on graft survival is favorable. Finally, formidable counselling as well as postoperative monitoring for both donors and recipients is crucial to minimize urolithiasis-related morbidity.

    Introduction STAT4 (signal transducer and activator of transcription 4) is involved in the regulation of innate and adaptive immune responses. Some studies have suggested that STAT4 may be involved in the immune response after graft transplantation. Several polymorphisms in the STAT4 gene have been identified. The most commonly studied polymorphism in the STAT4 gene is rs7574865. In our study, we examined whether this polymorphism is associated with the early and late functions of renal allografts. Material and methods A total of 270 recipients of first renal transplants were included in the study. Single nucleotide polymorphisms (SNPs) within the STAT4 gene were genotyped using TaqMan genotyping assays. Results There were no statistically significant associations between the STAT4 gene rs7574865 polymorphism and delayed graft function, acute rejection, chronic allograft dysfunction, post-transplant diabetes mellitus, or creatinine serum concentrations after transplantation. Conclusions Our results suggest a lack of association between the STAT4 rs7574865 SNP and kidney allograft function in the Polish population. PMID:27833442

    In clinical practice, the glomerular filtration rate (GFR) is often determined with serum creatinine. However, studies have shown cystatin C to be a better parameter for the diagnosis of impaired renal function. We compared GFR estimated by plasma cystatin C with GFR estimated by serum creatinine in a sample of 50 pediatric renal transplant recipients and 24 healthy children. The correlation between GFR estimated by serum creatinine and by cystatin C was significant (r = 0.75; P < 0.001, Person's correlation); however, in pediatric kidney transplant recipients, the GFR was 6.7 mL/min lower when determined using cystatin C rather than serum creatinine. Moreover, using GFR estimated by cystatin C we found that 42% of the pediatric kidney transplant recipients had an estimated GFR <60 mL.min-1.1.73 (m(2))-1, whereas when GFR was estimated by the serum creatinine formula only 16% of the children had values below this cutoff point indicative of chronic kidney disease (P < 0.001). We conclude that, in pediatric kidney transplant recipients, estimation of GFR yields lower values when cystatin C is used rather than serum creatinine.

    Autosomal dominant polycystic kidney disease (ADPKD), the most common form of polycystic kidney disease (PKD), is a disorder with characteristics of neoplasia. However, it is not known whether renal transplant recipients with PKD have an increased risk of cancer. Data from the Scientific Registry of Transplant Recipients, which contains information on all solid organ transplant recipients in the United States, were linked to 15 population-based cancer registries in the United States. For PKD recipients, we compared overall cancer risk with that in the general population. We also compared cancer incidence in PKD versus non-PKD renal transplant recipients using Poisson regression, and we determined incidence rate ratios (IRRs) adjusted for age, sex, race/ethnicity, dialysis duration, and time since transplantation. The study included 10,166 kidney recipients with PKD and 107,339 without PKD. Cancer incidence in PKD recipients was 1233.6 per 100,000 person-years, 48% higher than expected in the general population (standardized incidence ratio, 1.48; 95% confidence interval [95% CI], 1.37 to 1.60), whereas cancer incidence in non-PKD recipients was 1119.1 per 100,000 person-years. The unadjusted incidence was higher in PKD than in non-PKD recipients (IRR, 1.10; 95% CI, 1.01 to 1.20). However, PKD recipients were older (median age at transplantation, 51 years versus 45 years for non-PKD recipients), and after multivariable adjustment, cancer incidence was lower in PKD recipients than in others (IRR, 0.84; 95% CI, 0.77 to 0.91). The reason for the lower cancer risk in PKD recipients is not known but may relate to biologic characteristics of ADPKD or to cancer risk behaviors associated with ADPKD.

    The development of anti-donor humoral responses after transplantation associates with higher risks for acute rejection and 1-year graft survival in adults, but the influence of humoral immunity on transplant outcomes in children is not well understood. Here, we studied the evolution of humoral immunity in low-risk pediatric patients during the first 2 years after renal transplantation. Using data from 130 pediatric renal transplant patients randomized to steroid-free (SF) or steroid-based (SB) immunosuppression in the NIH-SNSO1 trial, we correlated the presence of serum anti-HLA antibodies to donor HLA antigens (donor-specific antibodies) and serum MHC class 1-related chain A (MICA) antibody with both clinical outcomes and histology identified on protocol biopsies at 0, 6, 12, and 24 months. We detected de novo antibodies after transplant in 24% (23% of SF group and 25% of SB group), most often after the first year. Overall, 22% developed anti-HLA antibodies, of which 6% were donor-specific antibodies, and 6% developed anti-MICA antibody. Presence of these antibodies de novo associated with significantly higher risks for acute rejection (P=0.02), chronic graft injury (P=0.02), and decline in graft function (P=0.02). In summary, antibodies to HLA and MICA antigens appear in approximately 25% of unsensitized pediatric patients, placing them at greater risk for acute and chronic rejection with accelerated loss of graft function. Avoiding steroids does not seem to modify this incidence. Whether serial assessments of these antibodies after transplant could guide individual tailoring of immunosuppression requires additional study.

    The risk of contrast-induced nephropathy (CIN) in renal transplant recipients is increased in diabetics, patients with impaired basal kidney function, patients in shock, patients presenting with acute emergency and in old age recipients. Approximately one-third of all hospitalized patients with acute kidney injury is attributed to CIN. In the United States, it is the third leading cause of hospital-acquired renal failure. Therefore, efforts should be directed to minimize CIN-related morbidity and mortality as well as to shorten hospital stay. While the role of peri-procedural prophylactic hydration with saline is unequivocal; the use of acetyl cysteine is not based on robust evidence. The utility of theophylline, aminophylline, calcium channel blockers, natriuretic peptide, and diuretics does not have proven role in attenuating CIN incidence. We aim to analyze the evidence for using various protocols in published literature to limit CIN-associated morbidity and mortality, particularly during surveillance of the renal allograft survival.

    Drug-induced interstitial nephritis is one of the causes of graft dysfunction in renal transplant recipients. Although commonly implicated as a cause of drug-induced interstitial nephritis in the general population, proton pump inhibitor-induced interstitial nephritis has not yet been reported in renal transplant recipients. Trimethoprim-sulfamethoxazole is responsible for most cases of interstitial nephritis in this population. Here, we describe the first case of proton pump inhibitor-related interstitial nephritis in a renal transplant recipient.

    Chronic kidney disease (CKD) is a complex disorder. As genome-wide association studies identified cubilin gene CUBN as a locus for albuminuria, and urinary protein loss is a risk factor for progressive CKD, we tested the hypothesis that common genetic variants in CUBN are associated with end-stage renal disease (ESRD) and proteinuria. First, a total of 1142 patients with ESRD, admitted for renal transplantation, and 1186 donors were genotyped for SNPs rs7918972 and rs1801239 (case-control study). The rs7918972 minor allele frequency (MAF) was higher in ESRD patients comparing to kidney donors, implicating an increased risk for ESRD (OR 1.39, p = 0.0004) in native kidneys. Second, after transplantation recipients were followed for 5.8 [3.8–9.2] years (longitudinal study) documenting ESRD in transplanted kidneys – graft failure (GF). During post-transplant follow-up 92 (9.6%) cases of death-censored GF occurred. Donor rs7918972 MAF, representing genotype of the transplanted kidney, was 16.3% in GF vs 10.7% in cases with functioning graft. Consistently, a multivariate Cox regression analysis showed that donor rs7918972 is a predictor of GF, although statistical significance was not reached (HR 1.53, p = 0.055). There was no association of recipient rs7918972 with GF. Rs1801239 was not associated with ESRD or GF. In line with an association with the outcome, donor rs7918972 was associated with elevated proteinuria levels cross-sectionally at 1 year after transplantation. Thus, we identified CUBN rs7918972 as a novel risk variant for renal function loss in two independent settings: ESRD in native kidneys and GF in transplanted kidneys. PMID:22574174

    Live donors are a continuing source of organ grafts for solid organ transplantation in Asia. Ethical issues surrounding the development of living donor organ transplantation in Eastern countries are different from those in Western countries. Donor safety is still the paramount concern in any donor operation. Issues on organ trafficking remain societal concerns in low-income nations. Religion, cultural background, economic prerogatives, and timely legislation contribute to the social acceptance and maturation of organ donation.

To what extent a renal transplant recipient is at risk for reactivation of polyoma virus during pregnancy remains unknown. We hereby report successful pregnancy outcome in a renal transplant recipient with a known history of BK virus nephropathy treated with cidofovir i.v. To our knowledge, this is the first published experience with a successful pregnancy in renal transplant recipients with known history of polyomavirus-associated nephropathy.

    Background. Renal re-transplants are increasing in number, due to many first renal transplant patients coming back to dialysis treatment. There are controversial opinions about the evolution of these re-transplanted patients. The aim of our study is to analyse the prognosis of patients and grafts under a renal re-transplant. Methods. This was a retrospective study of 579 renal re-transplants realized in 15 Spanish different centres in the years 1990, 1994, 1998 and 2002 including all renal re-transplants realized in the above-mentioned centres during the same periods. Results. During the follow-up period, 8.81% of patients died. The actuarial patient survival was 85% at 10 years and 80% at 15 years. Principal reasons of death were the same as normal for the renal transplanted patient: cardiovascular (30.77%), infectious (13.46%) and neoplastic (13.46%). During the period of follow-up, 28.6% of the grafts were lost. The actuarial graft survival was 75% at 10 years and 58% at 15 years. Causes of graft loss are very similar to those described in literature. Conclusion. Renal re-transplant is a kind of substitute renal treatment with excellent clinical results that allow to take it as a first-order modality of treatment when the first renal transplant has failed.

    The aim of the present study was to determine whether there is an association between serum free light chains (sFLC) quantification and the development of post-transplant lymphoproliferative disorder (PTLD), using serum samples from a nested case-control cohort of patients with renal transplant. Ten new cases of PTLD and 46 controls were enrolled. Additional comparison groups consisted of five human immunodeficiency virus (HIV)-infected individuals, five with untreated Hodgkin lymphoma and six normal individuals. Serum κ and λ FLC concentrations were measured by nephelometry and compared with reference ranges (normal and renal ranges). κ and/or λ were above the normal range in 90% of cases and in 65% of matched controls. There was no statistically significant difference between all groups, except for λ FLC concentrations between cases of PTLD and normal individuals (p = 0.016). The κ/λ sFLC ratios of cases and controls were within the renal range and normal range. Our results suggest that sFLC are not useful to predict PTLD development in renal transplant recipients.

    We compared growth rates by modality over a 6- to 14-month period in 1,302 US pediatric end-stage renal disese (ESRD) patients treated during 1990. Modality comparisons were adjusted for age, sex, race, ethnicity, and ESRD duration using linear regression models by age group (0.5 to 4 years, 5 to 9 years, 10 to 14 years, and 15 to 18 years). Growth rates were higher in young children receiving a transplant compared with those receiving dialysis (ages 0.5 to 4 years, delta = 3.1 cm/yr v continuous cycling peritoneal dialysis [CCPD], P < 0.01; ages 5 to 9 years, delta = 2.0 to 2.6 cm/yr v CCPD, chronic ambulatory peritoneal dialysis (CAPD), and hemodialysis, P < 0.01). In contrast, growth rates in older children were not statistically different when comparing transplantation with each dialysis modality. For most age groups of transplant recipients, we observed faster growth with alternate-day versus daily steroids that was not fully explained by differences in allograft function. Younger patients (<15 years) grew at comparable rates with each dialysis modality, while older CAPD patients grew faster compared with hemodialysis or CCPD patients (P < 0.02). There was no substantial pubertal growth spurt in transplant or dialysis patients. This national US study of pediatric growth rates with dialysis and transplantation shows differences in growth by modality that vary by age group.

    The review paper summarizes the advantages of the living donor kidney transplantation aiming that this kind of activity should get more support in Hungary. It is a general phenomenon overall the world, that there is no more possibility to increase the number of cadaver transplantations, and the outcome of them is also worsening because of the accumulation of aged patients with long time period of dialysis treatment. The paper points out the better results of living donor kidney transplantation underlining that the kidney long term survival, in general, is 10% over the cadaver kidney survival with significant less complication. The indication of living related and unrelated donor kidney transplantation is reported and the harmless of donor kidney removal demonstrated. An important part of the review contains the ethical, legal and social issue of the living donation, moreover, its economical benefit. It shows that in certain countries the living donation becomes in the forefront of the transplantation activity, which demonstrates from statistical point of view the overall benefit in comparison to cadaver transplantation. Based on the experience of those countries, which are performing this type of transplantation for a long time ago recommendation is given what should be the methodology to increase the activity in this field of transplantation.

    Various types of extracorporeal membrane oxygenation methods have been used in liver transplant operations. The main indications are portopulmonary or hepatopulmonary syndromes and other cardiorespiratory failure syndromes that are refractory to conventional therapy. There is little literature available about extracorporeal membrane oxygenation, especially after liver transplant. We describe our experience with 2 patients who had living-related liver transplant. A 69-year-old woman had refractory aspergillosis pneumonia and underwent pumpless extracorporeal lung assist therapy 4 weeks after liver transplant. An 8-month-old boy with biliary atresia underwent urgent liver transplant; he received venoarterial extracorporeal membrane oxygenation therapy on postoperative day 1. Despite our unsuccessful experience with 2 patients, extracorporeal membrane oxygenation and pumpless extracorporeal lung assist therapy for liver transplant patients may improve prognosis in selected cases.

    Introduction Urological complications after renal transplantation occur in between 2.5% and 30% of all graft recipients. The aim of the study was to present 7 years of experience in urological treatment of patients with a transplanted kidney. We aimed to identify retrospectively late urological complications in renal transplant recipients at a single center and analyze the treatment modalities and their outcome. Material and methods Between January 2008 and December 2014, a total of 58 patients after KTX were treated in the Department of Urology because of post-transplant urological complications that occurred during follow-up at the Transplant Outpatient Department. Retrieved data were analysed in retrospectively. Results In the group of 38 patients with ureteral stenosis (Clavien grade III), 29 patients underwent endoscopy, 8 open surgical procedures and one both endoscopic and open operation. Ten patients were admitted with symptomatic lymphocoele (Clavien III), of which 9 were successfully treated with drainage and one with surgical marsupialization. Because of urolithiasis in the grafted kidney (Clavien grade III), 4 patients were treated with ureterorenoscopic lithotripsy (URSL) and one only with the extracorporeal shock wave lithotripsy (ESWL) procedure. Five urethral strictures plasties and one graftectomy because of purulent pyelonephritis were also conducted. The average age in the group of recipients who experienced urologic complications was similar (46.1 vs. 47.8) to those without complications. There was no vesicoureteral reflux or ureteral necrosis requiring surgical intervention, no graft loss and death related to urological complication and treatment. Conclusions Most complications could be successfully treated with endourological procedures. The kidney function improved in the majority of patients. PMID:27730001

    Despite the known benefits of kidney transplant, less than 30% of the 615000 patients living with end-stage renal disease (ESRD) in the United States have received a transplant. More than 100000 people are presently on the transplant waiting list. Although the shortage of kidneys for transplant remains a critical factor in explaining lower transplant rates, another important and modifiable factor is patients’ lack of comprehensive education about transplant. The purpose of this article is to provide an overview of known best practices from the broader literature that can be used as an evidence base to design improved education for ESRD patients pursuing a kidney transplant. Best practices in chronic disease education generally reveal that education that is individually tailored, understandable for patients with low health literacy, and culturally competent is most beneficial. Effective education helps patients navigate the complex health care process successfully. Recommendations for how to incorporate these best practices into transplant education design are described. Providing more ESRD patients with transplant education that encompasses these best practices may improve their ability to make informed health care decisions and increase the numbers of patients interested in pursuing transplant.

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

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

    Low bone remodeling and relatively low serum parathyroid hormone (PTH) levels characterize adynamic bone disease (ABD). The impact of renal transplantation (RT) on the course of ABD is unknown. We studied prospectively 13 patients with biopsy-proven ABD after RT. Bone histomorphometry and bone mineral density (BMD) measurements were performed in the 1st and 12th months after RT. Serum PTH, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, and osteocalcin were measured regularly throughout the study. Serum PTH levels were slightly elevated at transplantation, normalized at the end of the third month and remained stable thereafter. Bone biopsies performed in the first month after RT revealed low bone turnover in all patients, with positive bone aluminum staining in 5. In the 12th month, second biopsies were performed on 12 patients. Bone histomorphometric dynamic parameters improved in 9 and were completely normalized in 6, whereas no bone mineralization was detected in 3 of these 12 patients. At 12 months post-RT, no bone aluminum was detected in any patient. We also found a decrease in lumbar BMD and an increase in femoral BMD. Patients suffering from ABD, even those with a reduction in PTH levels, may present partial or complete recovery of bone turnover after successful renal transplantation. However, it is not possible to positively identify the mechanisms responsible for the improvement. Identifying these mechanisms should lead to a better understanding of the physiopathology of ABD and to the development of more effective treatments.

    Background In France, there are important regional disparities of access to the renal transplant waiting list and transplantation. Our objectives were to compare the characteristics of patients with end-stage renal disease (ESRD) of two French regions (Ile-de-France and Bretagne) and to identify determinants of access to the waiting list and subsequent transplantation, with a focus on temporary inactive status (TIS) periods. Methods All 18–80-year-old incident patients who started dialysis in Ile-de-France or Bretagne between 2006 and 2009 were included (n = 6160). Associations between patients' characteristics and placement on the waiting list or transplantation were assessed using a Fine and Gray model to take into account the competing risk of death and living donor transplantation. Results At the end of the follow-up (31 December 2013), more patients had undergone transplantation in Bretagne than in Ile-de-France (30 versus 27%), although the percentage of waitlisted patients was higher in Ile-de-France than in Bretagne (47 versus 33%). More patients were on TIS and with a longer median TIS duration in Ile-de-France. Independent of age and clinical characteristics, patients in Bretagne were less likely to be waitlisted than those in Ile-de-France [subdistribution hazard ratio 0.77 (95% confidence interval 0.7–0.9)]. After waitlisting, patients in Bretagne were four times more likely to be transplanted. Conclusions Our study highlights clinical practice differences in Bretagne and Ile-de-France and shows that facilitating access to the waiting list is not sufficient to improve access to renal transplantation, which also depends on organ availability.

    Menstrual problem is common among women with chronic kidney disease, and patients with end-stage renal disease usually have amenorrhea. The rate of pregnancy in women on dialysis is low. Fetal survival in this population has improved, with half of such pregnancies resulting in delivery of a live infant. However, prematurity remains common and accounts for the low-birth weight of these infants. Intensifying hemodialysis by increasing the frequency of treatments is associated with longer gestation and increased likelihood of a successful pregnancy. Intense hemodialysis also improves the control of maternal intravascular volume and reduces the risk of hypotension due to excessive ultrafiltration. Women with chronic kidney disease tend to experience decreased libido and reduced ability to reach orgasm. Sexual difficulties in uremic patients are often worsened by hemodialysis, with a lowered frequency of intercourse, reduced sexual desire, and an increased incidence of sexual failure. There have been ongoing improvements in survival and quality of life after kidney transplantation. In most patients, sexual desire increases significantly after successful transplantation; however, improvement in the frequency of sexual activity and the overall sexual satisfaction is not as high as that in sexual desire. These have been accompanied by an improvement in reproductive function. Pregnancy success rate exceeds 90% after the first trimester in women with kidney transplant. Contraceptive counseling should be provided before transplantation, because ovulatory cycles may begin within 1 to 2 months after transplantation in women with functioning grafts. Breastfeeding is discouraged for patients taking any immunosuppressive drugs.

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

    Viral infections such as influenza are an important cause of morbidity following organ transplantation. We evaluated the immunogenicity of a commercially available influenza vaccine in pediatric renal transplant recipients in a two-phase, prospective study. In phase one, 47 transplant patients and seven control subjects with bronchopulmonary dysplasia received influenza vaccine. Sera were collected at the time of vaccination and 6 wk later. In phase two, sera from 18 transplant recipients and 47 healthy adults who had received the same vaccine were collected 6-12 months after vaccination. Antibody titers to the A/Taiwan/1/86 antigen were measured with hemagglutination inhibition assay in both phases of the study. Vaccine was well tolerated in all subjects. No vaccinated patient required hospitalization for complications of influenza infection. Vaccination did not increase the frequency of acute allograft rejection. In phase one, 43 patients (91%) and 5 controls (71%) either seroconverted (developed a fourfold or greater rise in titer), or developed post-vaccination titers > or = 1:160 (p = NS). Among the transplant recipients, non-seroconverters had a higher pre-vaccination geometric mean antibody titer (GMT) than those who seroconverted. Seroconversion developed independently of whether patients received double or triple immunosuppression. In phase two, post-vaccination GMT were similar for patients and control subjects at 11.5 and 8 months post-vaccination, respectively. In our study, influenza vaccination produced equivalent humoral immunity in transplant recipients and normal subjects. Routine influenza vaccination should be performed annually in this high-risk population.

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

    Catalytic antibodies are immunoglobulins endowed with enzymatic activity. Catalytic IgG has been reported in several human autoimmune and inflammatory diseases. In particular, low levels of catalytic IgG have been proposed as a prognostic marker for chronic allograft rejection in patients undergoing kidney transplant. Kidney allograft is a treatment of choice for patients with end-stage renal failure. Intravenous immunoglobulins, a therapeutic pool of human IgG, is used in patients with donor-specific antibodies, alone or in conjunction with other immunosuppressive treatments, to desensitize the patients and prevent the development of acute graft rejection. Here, we followed for a period of 24 months the levels of catalytic IgG towards the synthetic peptide Pro-Phe-Arg-methylcoumarinimide in a large cohort of patients undergoing kidney transplantation. Twenty-four percent of the patients received IVIg at the time of transplantation. Our results demonstrate a marked reduction in levels of catalytic antibodies in all patients three months following kidney transplant. The decrease was significantly pronounced in patients receiving adjunct IVIg therapy. The results suggests that prevention of acute graft rejection using intravenous immunoglobulins induces a transient reduction in the levels of catalytic IgG, thus potentially jeopardizing the use of levels of catalytic antibodies as a prognosis marker for chronic allograft nephropathy.

    Radionuclide scintigraphy is a safe and accurate means of detecting postoperative urologic complications in renal transplant recipients. Early identification of urinary leakage coupled with aggressive intervention significantly reduces the associated morbidity and mortality. Perivesical extravasate may be difficult to distinguish from adjacent or nearby bladder activity on scintiscan. Clarification of actual bladder contour and determination of its exact location within the pelvis may resolve such uncertainties. We describe imaging techniques that define the anatomic extent of the bladder and demonstrate our scintigraphic assessment of perivesical extravasation.

    We report the case of a renal transplant recipient with pulmonary and splenic mucormycosis whose demise was accelerated by a myocardial abscess. Once pulmonary and splenic mucormycosis was diagnosed, liposomal amphotericin B was started and immunosuppressant treatments were discontinued. The pulmonary cavities regressed during treatment, but new myocardial and peri-allograft abscesses developed. The myocardial abscess diffusely infiltrated the left ventricular wall and was associated with akinesia, which led to sudden cardiac arrest. This case demonstrates a rare manifestation of mucormycosis and highlights the fatality and invasiveness of this infection.

    A 45-year-old male recipient of a renal allograft was admitted because of a giant oesophageal ulcer coinciding with leucopoenia. An extensive workup revealed no explanation for the ulcer and leucopoenia. Our final diagnosis by exclusion was an idiopathic giant oesophageal ulcer and late-onset neutropenia as consequences of rituximab induction therapy given during the transplant procedure. The patient fully recovered after treatment with prednisone. However, after four months, the ulcer and leucopoenia recurred and again successfully responded to treatment with prednisone.

    FK506 is a novel immunosuppressive agent which is approximately 100 times as potent as cyclosporine in vitro. In this initial trial, 65 renal transplant patients of high complexity received primary FK506 immunosuppression. Overall, graft and patient survival rates are 80% and 98.5%, respectively. A major advantage of FK506 is its potency with relatively few side effects, which has permitted elimination of steroids in 31 (60%) of these patients. Because of these encouraging results, a randomized trial comparing the therapeutic efficacy and toxicity of FK506 and cyclosporine is currently underway at our institution.

    Renal dysfunction prior to liver transplantation has a marked impact on post-transplant kidney outcomes. The aim of this study was to assess post-transplant renal function in patients with chronic kidney disease (CKD) receiving orthotopic liver transplantation (OLT) alone. METHODS Retrospective review of 40 OLT recipients with pre-transplant CKD (serum creatinine ≥ 2 mg/dl for at least 3 months) at the University of Pennsylvania from February 2002 to July 2010. Primary outcome was estimated glomerular filtration rate (eGFR) up to 3 years post-transplant. Secondary outcomes included incidence of stage 4 CKD (eGFR < 30 ml/min), need for renal replacement therapy (RRT), meeting criteria for kidney transplant listing (eGFR ≤ 20 ml/min), and mortality. RESULTS Median patient age was 56.5 years and 48% patients had pre-transplant diabetes. Median serum creatinine at transplant was 2.7 mg/dl (eGFR 24 ml/min). Median eGFR at 1, 2, and 3 years post-transplant was 35, 34, and 37 ml/min respectively. Twelve patients (30%) required RRT at a median of 1.21 years posttransplant and 16 (40%) achieved an eGFR ≤ 20 ml/min at 1.09 years post-transplant. Mortality was 35% at a median of 1.60 years post-transplant. CONCLUSIONS OLT recipients with pre-transplant CKD have a substantial burden of post-transplant renal dysfunction and high short-term mortality, questioning the rationale for OLT alone in this population.

    A long-term renal transplant patient who was regularly followed up in the transplant clinic with stable renal allograft function was found to have elevated parathyroid hormone (PTH) levels on a biointact PTH assay. The elevated PTH levels were resistant to suppression on increasing doses of 1-alfacalcidol. Detailed history taking and clinical examination revealed the reason for apparent resistance to therapy.

    We previously described early results of a nonchimeric operational tolerance protocol in human leukocyte antigen (HLA)-identical living donor renal transplants and now update these results. Recipients given alemtuzumab, tacrolimus/MPA with early sirolimus conversion were multiply infused with donor hematopoietic CD34(+) stem cells. Immunosuppression was withdrawn by 24 months. Twelve months later, operational tolerance was confirmed by rejection-free transplant biopsies. Five of the first eight enrollees were initially tolerant 1 year off immunosuppression. Biopsies of three others after total withdrawal showed Banff 1A acute cellular rejection without renal dysfunction. With longer follow-up including 5-year posttransplant biopsies, four of the five tolerant recipients remain without rejection while one developed Banff 1A without renal dysfunction. We now add seven new subjects (two operationally tolerant), and demonstrate time-dependent increases of circulating CD4(+) CD25(+++) CD127(-) FOXP3(+) Tregs versus losses of Tregs in nontolerant subjects (p < 0.001). Gene expression signatures, developed using global RNA expression profiling of sequential whole blood and protocol biopsy samples, were highly associative with operational tolerance as early as 1 year posttransplant. The blood signature was validated by an external Immune Tolerance Network data set. Our approach to nonchimeric operational HLA-identical tolerance reveals association with Treg immunophenotypes and serial gene expression profiles.

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

    Guidelines recommend restricting simultaneous liver-kidney (SLK) transplant to candidates with prolonged dialysis or estimated glomerular filtration rate (eGFR) <30 ml/min/1.73m2 for 90 days. However, few studies exist to support the latter recommendation. Using SRTR and Medicare dialysis data, we assembled a cohort of 4997 liver transplant recipients from 2/27/2002–1/1/2008. Serial eGFRs were calculated from serum creatinines submitted with MELD reports. We categorized recipients by eGFR patterns in the 90 days pre-transplant: Group 1 (eGFR always >30), Group 2 (eGFR fluctuated), Group 3 (eGFR always <30) and Group 4 (short-term dialysis). For Group 2, we characterized fluctuations in renal function using time-weighted mean eGFR. Among liver-alone recipients in Group 3, the rate of end-stage renal disease (ESRD) by 3 years was 31%, versus <10% for other groups (p<0.001). In multivariable Cox regression, eGFR Group, diabetes (HR 2.65, p<0.001) and black race (HR 1.83, p=0.02) were associated with ESRD. Among liver-alone recipients in Group 2, only diabetics with time-weighted mean eGFR<30 had a substantial ESRD risk (25.6%). In summary, among liver transplant candidates not on prolonged dialysis, SLK should be considered for those whose eGFR is always <30 and diabetic candidates whose weighted mean eGFR is <30 for 90 days.

    Hypertension is common in children after renal transplantation and is associated with multiple factors. Data regarding the prevalence of post-transplant hypertension and the relationship between immunosuppressive drugs and the persistence of hypertension in a large population of North American children have not been available. This study was designed by the North American Pediatric Renal Transplant Cooperative Study to evaluate in a large diverse multicenter population of children the prevalence of hypertension post transplantation, the type of antihypertensive medications used to treat this hypertension and to determine the relationship between the blood pressure control and the immunosuppressive therapy. Analysis of 277 patients showed the following: (1) 70% of recipients required antihypertensive medications 1 month post transplant compared with 48% pre transplant; the incidence decreased to 59% at 24 months; (2) the majority of children received multiple drug therapy to control blood pressure; (3) hypertension can be controlled effectively despite inherent etiological factors, such as allograft source, prior hypertension and immunosuppressive therapy.

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

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

    Adult-to-adult living donors and recipients were studied to characterize patterns of liver growth and identify associated factors in a multicenter study. Three hundred and fifty donors and 353 recipients in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) receiving transplants between March 2003 and February 2010 were included. Potential predictors of 3-month liver volume included total and standard liver volumes (TLV and SLV), Model for End-Stage Liver Disease (MELD) score (in recipients), the remnant and graft size, remnant-to-donor and graft-to-recipient weight ratios (RDWR and GRWR), remnant/TLV, and graft/SLV. Among donors, 3-month absolute growth was 676 ± 251 g (mean ± SD), and percentage reconstitution was 80% ± 13%. Among recipients, GRWR was 1.3% ± 0.4% (8 < 0.8%). Graft weight was 60% ± 13% of SLV. Three-month absolute growth was 549 ± 267 g, and percentage reconstitution was 93% ± 18%. Predictors of greater 3-month liver volume included larger patient size (donors and recipients), larger graft volume (recipients), and larger TLV (donors). Donors with the smallest remnant/TLV ratios had larger than expected growth but also had higher postoperative bilirubin and international normalized ratio at 7 and 30 days. In a combined donor-recipient analysis, donors had smaller 3-month liver volumes than recipients adjusted for patient size, remnant or graft volume, and TLV or SLV (P = 0.004). Recipient graft failure in the first 90 days was predicted by poor graft function at day 7 (HR = 4.50, P = 0.001) but not by GRWR or graft fraction (P > 0.90 for each). Both donors and recipients had rapid yet incomplete restoration of tissue mass in the first 3 months, and this confirmed previous reports. Recipients achieved a greater percentage of expected total volume. Patient size and recipient graft volume significantly influenced 3-month volumes. Importantly, donor liver volume is a

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

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

    In the 53 years since kidney transplantation was first performed, this procedure has evolved from a highly speculative biomedical endeavor to a medically viable and often standard course of therapy. Long-term survival is markedly improved among patients who receive a kidney compared with patients who remain on the waiting list for such an organ. As outcomes have improved and more clinical indications have emerged, the number of people awaiting transplantation has grown significantly. In stark contrast to the robust expansion of the waiting list, the number of available deceased donors has remained relatively constant over the last several years. The current mechanism for procuring kidneys relies on voluntary donations by the general public, with the primary motivation being altruism. However, in light of the ever-increasing waiting list, it is the researchers' belief that the current system needs to be revised if supply is ever going to meet demand. In response to this critical organ shortage, different programs have been developed in an attempt to increase organ donation. At present, however, no solution to the problem has emerged. This report begins by outlining the scope of the problem and current legislation governing the procurement of transplantable organs/tissues in the United States. It continues with an overview of different proposals to increase supply. It concludes by exploring some of the controversy surrounding the proposal to increase donation using financial incentives. Though the following discussion certainly has implications for other transplantable organs, this report focuses on kidney transplantation because the waiting list for kidneys is by far the longest of all waiting lists for solid organs; and, as kidney transplant carries the smallest risk to living donors, it is the least ethically problematic.

    Although cyclosporine has improved allograft survival in renal transplant patients, problems with drug toxicity remain, raising the question whether cyclosporine should be stopped at some point post-transplant. However, the relative safety of converting from cyclosporine to another immunosuppressive agent, or simply stopping cyclosporine remains an issue of debate and has not been evaluated in children. We have developed a protocol to convert children, who are 6 months post-transplant and have stable kidney function, from cyclosporine and prednisone to azathioprine and prednisone. Eleven children have undergone conversion because of suspected/potential nephrotoxicity or because of other difficulties with cyclosporine (expense, hirsutism). These children were compared with a control group of 12 children who met all criteria for conversion at 6 months but remained on cyclosporine. Allograft survival was similar in both groups but the children converted from cyclosporine experienced an improvement in renal function as measured by calculated creatinine clearance. There were no episodes of rejection for a period of 4 months post-conversion and all rejection episodes that developed subsequently occurred during or after the change from daily to alternate-day prednisone. We believe that conversion from cyclosporine to azathioprine can be accomplished safely in children with stable allograft function but long-term risks and benefits need further evaluation.

    Although hematopoietic stem cell transplantation is a valuable treatment in many life-threatening pediatric disorders, a large number of children who receive hematopoietic stem cell transplantation are faced with a variety of physical and psychological problems throughout this process. In this study, we explored the lived experiences of these children during their treatment to provide a better understanding of their main concerns, emotions, and expectations. The participants were six children, aged between 6 and 17 years, who underwent hematopoietic stem cell transplantation. Data were collected through individual, in-depth, and semistructured interviews. Using interpretive phenomenological analysis, the findings revealed that the children experienced "transplantation rejoicing" in this "difficult passage", which was associated with "deepening of family ties". Awareness of these experiences, feelings, and concerns can help in the development of more professional interventions to provide children with holistic care during their hospitalization.

    Chronic Kidney Disease (CKD) is a common health problem affecting 1 in 12 Americans. It is associated with elevated risks of mortality, cardiovascular disease, and high costs for the treatment of renal failure with dialysis or transplantation. Advances in CKD care are impeded by the lack of biomarkers for early diagnosis, assessment of the extent of tissue injury, estimation of disease progression, and evaluation of response to therapy. Such biomarkers should improve the performance of existing measures of renal functional impairment (estimated glomerular filtration rate, eGFR) or kidney damage (proteinuria). MicroRNAs (miRNAs) a class of small, non-coding RNAs that act as post-transcriptional repressors are gaining momentum as biomarkers in a number of disease areas. In this review, we examine the potential utility of miRNAs as promising biomarkers for renal disease. We explore the performance of miRNAs as biomarkers in two clinically important forms of CKD, diabetes and the nephropathy developing in kidney transplant recipients. Finally, we highlight the pitfalls and opportunities of miRNAs and provide a broad perspective for the future clinical development of miRNAs as biomarkers in CKD beyond the current gold standards of eGFR and albuminuria.

    ABO-incompatible living kidney transplantation (ABO-ILKT) has steadily become more widespread. However, the optimal immunosuppressive regimen for ABO-ILKT remains uncertain. We aimed to determine the longitudinal changes in the outcomes from ABO-ILKT compared with those from ABO-compatible living kidney transplantation (ABO-CLKT) over the last 25 years. Of 1195 patients who underwent living kidney transplantations (LKT) at our institute between 1989 and 2013, 1032-including 247 ABO-ILKT and 785 ABO-CLKT cases-were evaluated for graft survival, patient survival, infectious adverse events, and renal function. The patients were divided into four groups according to the transplantation era and ABO-compatibility. In the past decade, ABO-ILKT and ABO-CLKT recipients yielded almost equivalent outcomes with respect to the 9-year graft survival rates, which were 86.9% and 92.0%, respectively (hazard ratio [HR] 1.38, 95% confidence interval [CI] 0.59-3.22, p = 0.455). The graft survival rate for ABO-ILKT conducted between 2005 and 2013 was better than that for ABO-ILKT conducted between 1998 and 2004 (HR 0.30, 95% CI 0.13-0.72, p = 0.007). ABO-ILKT recipients showed substantial improvements in the graft survival rate over time. Graft survival was almost identical over the past decade, regardless of ABO-incompatibility. Currently, ABO-ILKT is an acceptable treatment for patients with end-stage renal disease.

    Aims and objectives: The purpose of this study was to examine the sleep quality and health-related quality of life (HRQOL) in patients after renal transplantation and to explore the relationship between the quality of sleep and the HRQOL. Background: Sleep disorders are still an important clinical problem after renal transplantation. Previous studies mainly focused on patients’ sleep quality before kidney transplant. More studies are needed to document sleep quality after renal transplantation. Design: A cross-sectional design was used in this study. Methods: A convenience sample of renal transplant recipients was recruited at an outpatient transplant clinic of a general hospital in Beijing, China. The Pittsburgh Sleep Quality Index (PSQI) was used to measure quality of sleep. The Medical Outcomes Study 36-item Short Form (MOS SF-36) was used to measure health-related quality of life. Results: The average PSQI score of the 204 renal transplant recipients was 5.81±3.52, significantly lower than the norm. Fifty (24.5%) recipients were classified as having poor sleep quality (global PSQI > 7). The mean scores of renal transplant recipients for SF-36 Mental Component Summary (MCS) and Physical Component Summary (PCS) were 47.57±6.71 and 48.26±9.66 respectively. Compared with residents in Sichuan province, recipients’ scores for SF-36 dimensions were statistically lower except the dimension of mental health. SF-36 scores of poor sleepers (PSQI > 7) were significantly lower than the good sleepers (PSQI ≤ 7) in both the MCS and PCS. Significant differences exist between the groups in physical function, bodily pain, vitality, and mental health dimensions. Conclusions: Sleep quality and HRQOL of patients after renal transplantation were lower than the norm. Poor sleep is associated with lower HRQOL. Relevance to clinical practice: Health professionals need to pay attention to sleep quality and HRQOL in renal transplant recipients and take appropriate measures to

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

    Blood group incompatibility remains a significant barrier to kidney transplantation. Approximately one-third of donors are blood group incompatible with their intended recipient. Options for these donor-recipient pairs include blood group incompatible transplantation or kidney paired donation. However, the optimal protocol for blood group incompatible transplantation is unknown. Protocols differ in techniques to remove ABO antibodies, titer targets and immunosuppression regimens. In addition, the mechanisms of graft accommodation to blood group antigens remain poorly understood. We describe a blood group incompatible protocol using pre-transplant therapeutic plasma exchange (TPE), high-dose intravenous immunoglobulin and rituximab in addition to prednisone, mycophenolate mofetil and tacrolimus. In this protocol, we do not exclude patients based on a high initial titer and do not implement post-transplant TPE. All 16 patients who underwent this protocol received a living donor transplant with 100 percent patient and graft survival, and no reported episodes of antibody-mediated rejection to date with a median follow-up of 2.6 years (range 0.75 to 4.7 years). We conclude that blood group incompatible transplantation can be achieved without post-transplant TPE. PMID:25739580

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

    Radio-hippurate scintigraphy has been used to study renal transplant function because of its unique advantages over other noninvasive methods. Despite a great sensitivity in diagnosing the existence of a functional problem the test lacks in specificity. In an effort to differentiate between acute tubular necrosis (ATN) and graft rejection (RJ) the authors preceded hippurate scintigraphy by measurements of renal flow transit time (TT). After an intravenous injection of 8 mCi of Tc-99m-sulfur-colloid flow curves from the kidney and the abdominal aorta in 1 sec intervals for 1 min were obtained. Renal transit time was mathematically calculated and corrected for bolus and circulatory differences by dividing it with the corresponding Aortic TT (corrected Renal TT(cRTT). Radiohippuran (O-I-131-Hippurate), 150 ..mu..Ci was injected subsequently and of the different computer generated parameters the 30 min net cortical residual (% of the peak) activity (Hippuran Residual Activity, HRA) was found more sensitive and reproducible for comparisons. Results of documented cases showed a statistically significant difference. Uncomplicated cases (usually on antirejection therapy) showed a tendency to increasing the cRTTs with time (not significantly) but their HRAs were significantly lower than in ATN and RJ (p< 0.001).

    Prolongation of the QTc interval, a risk factor for cardiac arrhythmias, has been observed in adult hemodialysis patients; there are few data on the QTc interval in children with chronic renal failure (CRF) and following renal transplantation (Tx). The purpose of our study was to determine the QTc interval in children with CRF and post renal Tx. Twenty children with CRF and 16 children with renal Tx who were followed at the University of California, Davis, underwent prospective EKG monitoring. The mean QTc interval in the CRF and post-Tx cohorts was normal at 407.9 ms and 408.2 ms, respectively. None of the children with CRF had QTc prolongation. Two Tx recipients had QTc prolongation; both had cardiac dilatation on echocardiography (ECHO). There was no correlation between the QTc interval and the creatinine clearance in either group. However, a significant correlation was noted between QTc prolongation and cardiac dilatation on ECHO in the Tx group (P=0.02, Fisher's exact test). In conclusion, QTc prolongation is uncommon in children with CRF and following Tx, in the absence of cardiac dilatation. However, caution is still needed before prescribing medications known to cause QTc prolongation.

    High-density lipoprotein (HDL) particles are involved in the protection against cardiovascular disease by promoting cholesterol efflux, in which accumulated cholesterol is removed from macrophage foam cells. We investigated whether HDL cholesterol efflux capacity is associated with cardiovascular mortality, all-cause mortality, and graft failure in a cohort of renal transplant recipients (n=495, median follow-up 7.0 years). Cholesterol efflux capacity at baseline was quantified using incubation of human macrophage foam cells with apolipoprotein B–depleted plasma. Baseline efflux capacity was not different in deceased patients and survivors (P=0.60 or P=0.50 for cardiovascular or all-cause mortality, respectively), whereas recipients developing graft failure had lower efflux capacity than those with functioning grafts (P<0.001). Kaplan–Meier analysis demonstrated a lower risk for graft failure (P=0.004) but not cardiovascular (P=0.30) or all-cause mortality (P=0.31) with increasing gender-stratified tertiles of efflux capacity. Cox regression analyses adjusted for age and gender showed that efflux capacity was not associated with cardiovascular mortality (hazard ratio [HR], 0.89; 95% confidence interval [95% CI], 0.67 to 1.19; P=0.43). Furthermore, the association between efflux capacity and all-cause mortality (HR, .79; 95% CI, 0.63 to 0.98; P=0.031) disappeared after further adjustment for potential confounders. However, efflux capacity at baseline significantly predicted graft failure (HR, 0.43; 95% CI, 0.29 to 0.64; P<0.001) independent of apolipoprotein A-I, HDL cholesterol, or creatinine clearance. In conclusion, this prospective study shows that cholesterol efflux capacity from macrophage foam cells is not associated with cardiovascular or all-cause mortality but is a strong predictor of graft failure independent of plasma HDL cholesterol levels in renal transplant recipients.

    The incidence and risk factors of posttransplant diabetes mellitus were evaluated in 1325 consecutive renal transplant recipients. Thirty-three (2.5%) patients developed diabetes mellitus requiring insulin therapy. Onset occurred a mean of 5.7 +/- 1.5 months following transplantation. The patients were compared with 33 paired-control kidney recipients. The patients were significantly older than the controls (46.8 +/- 1.9 vs. 40.6 +/- 2.1 years) (P<0.05), and chronic renal failure was more often related to interstitial nephritis (P<0.05). A family history of diabetes mellitus, the body mass index, ethnic origin, HLA phenotype, and the total doses of steroids and cyclosporine were similar in the two groups. The number of patients with at least one rejection episode was significantly higher among the diabetic patients (21 versus 9) but the number of episodes was similar. Diabetes occurred a mean of 1.1 +/- 0.3 months following rejection treatment. Intravenous pulsed prednisolone was always used for anti-rejection therapy. Insulin was withdrawn in 16 cases after a mean of 4 +/- 1 months, independently of steroid dosage reductions. Actuarial patient and graft survival rates were not significantly different, although 6-year outcome tended to be better in the controls (86% versus 93% for patient survival and 67% versus 93% for graft survival). This study suggests that pulsed steroid therapy might be the critical factor in the onset of posttransplant diabetes and that the risk is increased in older patients with chronic interstitial nephrititis.

    Levels of the endogenous nitric oxide synthase inhibitor asymmetrical dimethylarginine (ADMA) are elevated and endothelial progenitor cells (EPCs) decreased in patients undergoing renal transplantation (Tx) and may contribute to cardiovascular complications. In this study, we tested the hypothesis that elevated ADMA and decreased EPC can be positively influenced with regular physical exercise early after Tx. Blood samples for analysis of ADMA and EPC were obtained from randomly selected 64 patients after Tx who agreed to participate in a supervised aerobic exercise program for 6 months (group I). Samples were collected before the training began, 1 month after surgery (with stabilized renal function), and at 6 months after initiation. Sixty-two age, sex, human leukocyte antigens (HLA) typing, duration of previous dialysis, history of cardiovascular disease, and immunosupression regimen-matched transplant patients who did not exercise regularly were examined as controls (group II). There were no differences in ADMA levels and EPC count between both groups before the training program began. After 6 months of exercise, ADMA concentration in the group I decreased (3.50 ± 0.45 vs. 2.11 ± 0.35 μmol/L; P < .01) and was also lower comparing with group II (2.11 ± 0.23 vs. 3.25 ± 0.35 μmol/L; P < .01). In the same period, EPC cells increased from 2.085 ± 650 cells/mL versus 3.991 ± 560 cells/mL, P < .01 in group I; but in group II, changes were nonsignificant (P = .11). Blood lipids, HbA1c, insulin, and systolic blood pressure were also affected by the training program. Elevated ADMA level and decreased EPC count were significantly influenced by early regular exercise in patients after Tx.

    Solid organ transplantation has traditionally been governed by the rules of blood group compatibility. Thus, it has been demonstrated that crossing the ABO blood group barrier generally results in hyperacute rejection. However, the A2 subtype of the blood group A is a weaker antigen. Under certain circumstances, organs from donors with blood group A2 can be transplanted across the ABO blood group barrier into recipients of O or B blood type. Since 1986, 33 patients including 24 blood group O and 9 blood group B patients received A2 (30) or A2B (3) donor kidneys. Both cadaver donor (31) and living-related grafts (2) have been undertaken. The mean follow-up since transplantation for the 21 patients with functioning grafts is 36 months, with a 67.2% current graft survival. Immunosuppression for these transplants consisted of azathioprine, prednisone, and cyclosporine, often in combination with prophylactic OKT3 or antilymphocyte globulin as protocol dictated. Special immunosuppressive protocols such as splenectomy or plasmapheresis were not used. The serum of the potential recipient was analyzed for immunoglobulin G (IgG) and immunoglobulin M (IgM) forms of antibody against A1 and A2 red blood cells. There is a strong correlation between a low (less than or equal to 1:8) anti-A1 IgG titer and both early and long-term graft function. Recipients with an IgG titer greater than 1:8 in the pretransplant serum had a much higher incidence of early graft failure. We no longer recommend transplantation of A2 kidneys into O or B recipients with a pretransplant titer of greater than 1:8 but found that recipients with low titers have graft function rates essentially equal to those of ABO-compatible patients. Patients with blood group B have, over time, lower anti-A IgG titers than do blood group O patients. In addition, the graft survival among blood group B patients is 89% compared with 58% among group O recipients. This may be due to the generally low titers found in blood

    Renal transplant patients are at high risk of developing various infections causing morbidity and mortality. Invasive fungal infection has been recognized as a significant complication of organ transplantation. The major fungal infections in these patients are due to candida, aspergillus and mucormycosis. However, infection because of infrequently encountered fungi like hyaline molds, dematiaceous filamentous fungi and zygomycetes are increasing in immunocompromised hosts. Dematiaceous fungi are recognized pathogens in organ transplant recipients with skin and soft tissue infection. We report the case of a 37-year-old man, a renal transplant recipient who developed an asymptomatic dematiaceous fungal infection in submandibular salivary gland. He recovered after excision and antifungal therapy. PMID:27656452

    Renal failure is a common finding in patients undergoing orthotopic liver transplantation. The aim of the present study was to evaluate the incidence, prognostic value of pre, intra and postoperative factors and severity of renal dysfunction in patients who undergo liver transplantation. Therefore, the records of 38 consecutive adult patients were reviewed. Renal failure was defined arbitrarily as an increase in creatinine (> 1.5 mg/dl) and/or blood urea (> 80 mg/dl). Three patients were excluded of the final analysis (1 acute liver failure and 2 with a survival lower than 72 hs.) Twenty one of the 35 patients has renal failure after orthotopic liver transplantation. Six of these episodes developed early, having occurred within the first 6 days. Late renal impairment occurred in 15 patients within the hospitalization (40 +/- 10 days) (Mean +/- SD). In he overall series, liver function, evaluated by Child-Pugh classification, a higher blood-related requirements and cyclosporine levels were observed more in those who experienced renal failure than those who did not (p < 0.05). Early renal failure was related with preoperative (liver function) and intraoperative (blood requirements) factors and several causes (nephrotoxic drugs and graft failure) other than cyclosporine were present in patients who developed late renal impairment. No mortality. No mortality was associated with renal failure. We conclude that renal failure a) is a common finding after liver transplantation, b) the pathogenesis of this complication is multifactorial and, c) in not related with a poor outcome.

    Renal replacement therapy (RRT) for Brazilian children with uraemia has been utilized since 1970 in the state of Rio Grande do Sul. One hundred and eighty patients receiving this therapy between 1970 and 1988 have been reviewed. The annual acceptance rate of new paediatric patients in this period increased from 0.6 to 6.5 patients per million child population. Glomerulonephritis (36.1%) and pyelonephritis including urological anomalies (31.7%) were the most frequent causes of end-stage renal disease. Outpatient hospital haemodialysis was the primary form of dialytic treatment in patients 5-15 years of age. Continuous ambulatory peritoneal dialysis was more often used in patients less than 5 years of age. The survival after 1 year on dialysis was 79.9% for children aged 5-15 years starting dialysis during the period 1985-1988. Fluid overload with congestive heart failure and infection were the main causes of death in children on dialysis. Eighty-four children received 93 grafts; only 14 (15%) were from cadaveric donors. One-year patient and graft survival of first living-related donor transplants were 92.2% and 78.5% respectively during the period 1985-1988. Infection accounted for 43.5% of deaths after transplantation. We conclude that RRT is becoming increasingly successful for children in our region but that greater emphasis upon patient compliance with all forms of RRT and upon cadaver kidney donation is needed.

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

    Adenine phosphoribosyltransferase deficiency is a rare autosomal recessive disorder of uric acid metabolism that leads to formation and excretion of 2,8-dihydroxyadenine into urine. The low solubility of 2,8-dihydroxyadenine results in precipitation and formation of urinary crystals and renal stones. Patients with this disorder usually have recurrent nephrolithiasis and can develop nephropathy secondary to crystal precipitation in the renal parenchyma. The disease is most often underdiagnosed and can recur in renal transplant, causing graft failure. Lack of specific clinical manifestations, chemical and radiologic features identical to those shown with uric acid stones, and lack of awareness among clinicians are among the causes for the underdiagnoses of this treatable disease. Allopurinol, a xanthine dehydrogenase inhibitor, is the mainstay of treatment, supported by high fluid intake and dietary modifications. The possibility of adenine phosphoribosyl transferase deficiency should be considered in all cases of urolithiasis in children, patients with recurrent urolithiasis, and patients with urolithiasis associated with renal failure of unknown cause, including patients with end-stage renal disease and renal transplant recipients. Here, we report a case of a 41-year-old female patient who had a late diagnosis of 2,8-dihydroxyadenine nephropathy-induced end-stage renal disease, made on the native nephrectomy that accompanied the renal transplant, and who had a timely intervention that prevented recurrence in the graft.

    Fecal microbiota transplantation is a compelling treatment for recurrent Clostridium difficile infections, with potential applications against other diseases associated with changes in gut microbiota. But variability in fecal bacterial communities-believed to be the therapeutic agent-can complicate or undermine treatment efficacy. To understand the effects of transplant preparation methods on living fecal microbial communities, we applied a DNA-sequencing method (PMA-seq) that uses propidium monoazide (PMA) to differentiate between living and dead fecal microbes, and we created an analysis pipeline to identify individual bacteria that change in abundance between samples. We found that oxygen exposure degraded fecal bacterial communities, whereas freeze-thaw cycles and lag time between donor defecation and transplant preparation had much smaller effects. Notably, the abundance of Faecalibacterium prausnitzii-an anti-inflammatory commensal bacterium whose absence is linked to inflammatory bowel disease-decreased with oxygen exposure. Our results indicate that some current practices for preparing microbiota transplant material adversely affect living fecal microbial content and highlight PMA-seq as a valuable tool to inform best practices and evaluate the suitability of clinical fecal material.

    Percutaneous treatment of renal artery stenosis (RAS) is an accepted procedure and numerous reports have been published. However, experience with its use in RAS in the transplanted kidney in children is scarce. Since 1994 we have diagnosed RAS in seven children with the use of Doppler ultrasonography (US), confirming it with percutaneous angiography (PAG). In six of the seven patients percutaneous transluminal angioplasty (PTA) was performed. In one patient a metallic stent was placed due to the extension of the arterial lesion, and a second stent was placed in another child when a re-stenosis was diagnosed 1 month after the PTA. All patients presented with hypertension (de novo or 30% increase over previous values). After ruling out acute rejection, calcineurin inhibitor toxicity, and urinary obstruction, US was performed and, when an increase in arterial flux velocity was registered, PAG was also performed. Six children showed an increase in serum creatinine (Cr) and proteinuria. Blood pressure decreased after the procedure and Cr returned to previous levels in all children. One of the grafts was lost due to chronic transplant rejection 7 years later. The other children have a functioning kidney. Although this is a small group of patients, the consistently good results and the lack of reported experience prompted us to communicate our preliminary observation.

    Urinary tract infection (UTI) is the most common complication following kidney transplantation (KT), which could result in losing the graft. This study aims to identify the prevalence of bacterial UTI among KT recipients in Yemen and to determine the predisposing factors associated with post renal transplantation UTI. A cross sectional study included of 150 patients, who underwent KT was conducted between June 2010 and January 2011. A Morning mid-stream urine specimen was collected for culture and antibiotic susceptibility test from each recipient. Bacterial UTI was found in 50 patients (33.3%). The prevalence among females 40.3% was higher than males 29%. The UTI was higher in the age group between 41-50 years with a percentage of 28% and this result was statistically significant. Predisposing factors as diabetes mellitus, vesicoureteral reflux, neurogenic bladder and polycystic kidney showed significant association. High relative risks were found for polycystic kidney = 13.5 and neurogenic bladder = 13.5. The most prevalent bacteria to cause UTI was Escherichia coli represent 44%, followed by Staphylococcus saprophyticus 34%. Amikacin was the most effective antibiotic against gram-negative isolates while Ciprofloxacin was the most effective antibiotic against Staphylococcus saprophyticus. In conclusion, there is high prevalence of bacterial UTI among KT recipients in Yemen. Diabetes mellitus, vesicoureteral reflux, neurogenic bladder, polycystic kidney and calculi were the main predisposing factors.

    Background: Infectious disorders are a major cause of concern in renal transplant recipients (RTRs) leading to considerable morbidity and mortality. We studied the profile and outcomes of infectious disorders in a cohort of RTR. Materials and Methods: In this prospective, observational study, we evaluated all RTR who presented with the features of infection. We also included asymptomatic patients with microbiological evidence of infection. We excluded patients with acute rejection, drug toxicity, and malignancy. Descriptive statistics were used to analyze the results. Results: The study population (n = 45, 35 male and 10 female) had a mean age of 35.5 ± 10.4 years and follow-up after transplant was 2.1 ± 1.7 years. Urinary tract infection (UTI, n = 15) is the most common infection followed by tuberculosis (TB, n = 8), cytomegalovirus (n = 6), candidiasis (n = 7), and hepatitis (n = 11). Miscellaneous infections such as cryptosporidiosis and pneumocystis were seen in 10 patients. Simultaneous infections with two organisms were seen in 7 patients. Four patients succumbed to multiorgan dysfunction following sepsis, another 4 patients developed chronic graft dysfunction, while the remaining 35 RTR had a good graft function. Conclusion: Infectious complications are very common in the posttransplant period including UTI and TB. Further large scale studies are required to identify the potential risk factors leading to infections in RTR. PMID:28217592

    Patients with diabetes and end-stage renal failure are known to have a high risk for cardiac morbidity and mortality associated with renal transplantation. The most efficient method to determine preoperative cardiac risk has not been established. To determine the effectiveness of intravenous dipyridamole thallium imaging in predicting cardiac events, 40 diabetic renal transplant candidates were studied preoperatively in a prospective trial. The study group consisted of 40 patients whose average age was 42 years (range 27 to 64); 34 (85%) were hypertensive and 21 (53%) were cigarette smokers. Cardiac history included chest pain in 6 patients and prior myocardial infarction in 3 patients. Dipyridamole thallium imaging showed reversible defects in 9 patients, fixed defects in 8 patients and normal scans in 23 patients. Dipyridamole thallium imaging was performed using 0.56 mg/kg of dipyridamole infused intravenously over 4 minutes. Cardiac events occurred only in patients with reversible thallium defects, of which there were 6. Of these 6 patients, 3 had cardiac events before transplantation and 3 had them in the early postoperative phase (within 6 weeks of surgery). Of 21 patients who underwent renal transplantation, 3 had cardiac events within 6 weeks of transplantation. The average duration of follow-up was 11 months (range 1 to 21). Thus, dipyridamole thallium imaging is an effective method of identifying renal transplant candidates likely to develop cardiac complications. Routine coronary angiography may not be necessary to screen all renal transplant candidates for coronary artery disease before surgery.

    Background: Renal transplantation has long been considered the gold standard medical care for patients with end-stage renal disease. Candiduria continue to be a significant complication for renal transplant recipients. The risk of infections depends on the amount of immunosuppression and exposure to the potential pathogens. Objective: Molecular identification of Candida species isolated from renal transplant recipients with candiduria. Methods: Between 2009 and 2014, 62 Candida isolates were collected from 485 renal transplant recipients. All isolates were identified by PCR-RFLP profiles after digestion with the restriction enzyme MspI. Results: C. albicans (44%) and C. parapsilosis complex (5%) had the most and the least prevalence, respectively. Male to female ratio was 26/36, ranging in age from 19 to 62 years. Conclusion: Due to the fact that candiduria is connected with increased mortality in renal transplant recipients, precise identification of Candida species by molecular techniques can lead to an appropriate therapy among high risk patients. C. albicans remains the most prevalent species isolated from renal transplant recipients, Nevertheless, the number of non-C. albicans Candida species looks to be emerging. PMID:28078059

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

    Background Poor sleep quality (SQ) and daytime sleepiness (DS) are common in renal transplant (RTx) recipients; however, related data are rare. This study describes the prevalence and frequency of self-reported sleep disturbances in RTx recipients. Methods This cross-sectional study included 249 RTx recipients transplanted at three Swiss transplant centers. All had reported poor SQ and / or DS in a previous study. With the Survey of Sleep (SOS) self-report questionnaire, we screened for sleep and health habits, sleep history, main sleep problems and sleep-related disturbances. To determine a basis for preliminary sleep diagnoses according to the International Classification of Sleep Disorders (ICSD), 164 subjects were interviewed (48 in person, 116 via telephone and 85 refused). Descriptive statistics were used to analyze the data and to determine the frequencies and prevalences of specific sleep disorders. Results The sample had a mean age of 59.1 ± 11.6 years (60.2% male); mean time since Tx was 11.1 ± 7.0 years. The most frequent sleep problem was difficulty staying asleep (49.4%), followed by problems falling asleep (32.1%). The most prevalent sleep disturbance was the need to urinate (62.9%), and 27% reported reduced daytime functionality. Interview data showed that most suffered from the first ICSD category: insomnias. Conclusion Though often disregarded in RTx recipients, sleep is an essential factor of wellbeing. Our findings show high prevalences and incidences of insomnias, with negative impacts on daytime functionality. This indicates a need for further research on the clinical consequences of sleep disturbances and the benefits of insomnia treatment in RTx recipients. PMID:24112372

    The pharmacokinetics of cyclosporine and the relationship between blood levels and average drug concentration were prospectively evaluated in 18 children 1 month after renal transplantation. All children had normal renal function and no hepatic or gastrointestinal dysfunction. Cyclosporine was administered after an overnight fast, and serial blood samples were drawn over a 24-hour period. Analysis of cyclosporine levels was performed by means of monoclonal radio immunoassay on whole blood. Children were divided into three age groups for comparison: 2-5 years, 5-10 years, and > 10 years. There were no differences between age groups in serum protein, serum lipids, or hemoglobin levels, or in the pharmacokinetic parameters of cyclosporine except as follows: significant differences were noted in cyclosporine dose based on body weight, apparent steady-state volume of distribution, and apparent blood clearance, with the youngest children (2-5) requiring higher doses, a relative greater distribution, and exhibiting more rapid drug clearance than those > 10 years of age. In addition, we observed diurnal variation in trough levels, with morning levels (0 hr) significantly higher than those obtained in the evening (12 hours after administration of cyclosporine). Trough levels demonstrated a fair correlation with area under the concentration-time curve (AUC) and average concentration (Cav), but an abbreviated kinetic profile using cyclosporine levels 1 and 3.5 hours after administration accurately predicted AUC.

    ABO incompatibility has been considered as an important immunological barrier for renal transplantation. With the advent of effective preconditioning protocols, it is now possible to do renal transplants across ABO barrier. We hereby present a single center retrospective analysis of all consecutive ABOi renal transplants performed from November 2011 to August 2014. Preconditioning protocol consisted of rituximab, plasmapheresis and intravenous immunoglobulin (IVIG) and maintenance immunosuppression consisted of tacrolimus, mycophenolate sodium, and prednisolone. The outcome of these ABOi transplants was compared with all other consecutive ABO-compatible (ABOc) renal transplants performed during same time. Twenty ABOi renal transplants were performed during the study period. Anti-blood group antibody titer varied from 1:2 to 1:512. Patient and graft survival was comparable between ABOi and ABOc groups. Biopsy proven acute rejection rate was 15% in ABOi group, which was similar to ABOc group (16.29%). There were no antibody-mediated rejections in ABOi group. The infection rate was also comparable. We conclude that the short-term outcome of ABOi and ABOc transplants is comparable. ABOi transplants should be promoted in developing countries to expand the donor pool.

    This study was undertaken to compare the efficacy and safety of tacrolimus (Tac) with the microemulsion formulation of cyclosporin (CyA) in children undergoing renal transplantation. A 6-month, randomized, prospective, open, parallel group study with an open extension phase was conducted in 18 centers from nine European countries. In total, 196 pediatric patients (<18 years) were randomly assigned (1:1) to receive either Tac ( n=103) or CyA microemulsion ( n=93) administered concomitantly with azathioprine and corticosteroids. The primary endpoint was incidence and time to first acute rejection. Baseline characteristics were comparable between treatment groups. Tac therapy resulted in a significantly lower incidence of acute rejection (36.9%) compared with CyA therapy (59.1%) ( P=0.003). The incidence of corticosteroid-resistant rejection was also significantly lower in the Tac group compared with the CyA group (7.8% vs. 25.8%, P=0.001). The differences were also significant for biopsy-confirmed acute rejection (16.5% vs. 39.8%, P<0.001). At 1 year, patient survival was similar (96.1% vs. 96.6%), while 10 grafts were lost in the Tac group compared with 17 graft losses in the CyA group ( P=0.06). At 1 year, mean glomerular filtration rate (Schwartz estimate) was significantly higher in the Tac group (62+/-20 ml/min per 1.73 m(2), n=84) than in the CyA group (56+/-21 ml/min per 1.73 m(2), n=74, P=0.03). The most frequent adverse events during the first 6 months were hypertension (68.9% vs. 61.3%), hypomagnesemia (34.0% vs. 12.9%, P=0.001), and urinary tract infection (29.1% vs. 33.3%). Statistically significant differences ( P<0.05) were observed for diarrhea (13.6% vs. 3.2%), hypertrichosis (0.0% vs. 7.5%), flu syndrome (0.0% vs. 5.4%), and gum hyperplasia (0.0% vs. 5.4%). In previously non-diabetic children, the incidence of long-term (>30 days) insulin use was 3.0% (Tac) and 2.2% (CyA). Post-transplant lymphoproliferative disease was observed in 1 patient in the

    Ganciclovir alone or in combination with hyperimmunoglobulin is replacing other treatment modalities for the prophylactic treatment of cytomegalovirus (CMV) infections. No dose recommendations are available for oral ganciclovir therapy in children with impaired renal function after renal transplantation of a kidney from a CMV IgG-positive donor. We undertook a pharmacokinetic study in 14 pediatric renal transplant recipients who were CMV IgG negative and had received a graft from a CMV IgG-positive donor. We estimated the daily dosage of oral ganciclovir in relation to the glomerular filtration rate (GFR). Oral ganciclovir was administered at a starting dose of 3 x 1 g for children with a weight above 50 kg, 3 x 750 mg for children between 50 and 37.5 kg, and 3 x 500 mg for children between 37.5 and 24 kg. The starting dose was reduced by 50% for GFR values < or = 50 ml/min per 1.73 m2 and by 75% for GFR values < or = 25 ml/min per 1.73 m2. The daily dose was divided into three daily doses unless GFR was < 40 ml/ min per 1.73 m2, when only two daily doses were given. Doses were adjusted according to the measured plasma trough concentrations (c) using the simple formula: c(ganciclovir)(measured)/c(ganciclovir)(desired) = dosage rate(used)/dosage rate(adjusted). Mean stable plasma trough concentration was 0.91 +/- 0.68 microg/ml. The dosage rate, adjusted to a trough concentration of 1.0 microg/ml, correlated with the GFR. The dose per day could be calculated according to a simple equation for a GFR < 100 ml/min per 1.73 m2: dosage per day (mg/kg per day) = GFR. No CMV disease developed in any of the patients during oral ganciclovir, but 1 patient developed an acute rejection episode and a positive pp65 antigen 5 weeks after discontinuation of ganciclovir. The drug was well tolerated and without side effects.

    Currently in Brazil, living donor liver transplantation (LDLT) represents 8.5% of liver transplantation (LT), being the majority pediatric one. Up to now, according to Brazilian Organ Transplantation Association (ABTO) annual report, 2,086 procedures have been done nationwide, most of them in southeast and south regions. Based on national centers reports, biliary complication is the most common recipient postoperative complication (14.5–20.6%), followed by hepatic artery thrombosis (3.1–10.7%) and portal vein thrombosis (2.3–9.1%). Patient and graft overall 5-y survival correspond to 76% and 74%, respectively. Regarding the donor, morbidity rate ranges from 12.4% to 28.3%, with a national mortality rate of 0.14%. In conclusion, Brazilian LDLT programs enhance international experience that this is a feasible and safe procedure, as well as an excellent alternative strategy to overcome organs shortage.

    Different types of skin disorders are prevalent among kidney transplant recipients. The development of nodular skin lesions in these patients would usually raise a suspicion of Kaposi's sarcoma. We report a patient, who presented with nodular skin lesions one year post transplant, but the biopsy revealed a rare diagnosis - Mycobacterium fortuitum (M. fortuitum) infection of the skin, subcutaneous, and renal allograft. He was treated successfully with an initial two-week course of intravenous cefoxitin, followed by a six-month course of ciprofloxacin, clarithromycin, and co-trimoxazole. There are a few reported cases of M. fortuitum infection in renal transplant recipients in the literature - notably urinary tract infection, allograft infection, and psoas abscess, but to the best of our knowledge this is the first case demonstrating extensive infection involving the skin, subcutaneous tissue, and renal allograft. Physicians vested with the care of renal transplant patients should be aware of this rare infection in these patients.

    There is limited information on kidney transplant recipients with end-stage renal disease (ESRD) due to scleroderma. We conducted an observational study on kidney transplant recipients with ESRD due to scleroderma who received kidney transplant at our center between 01/1994 and 06/2013. During the study period, there were 10 kidney transplant recipients, all of whom were Caucasian females. Seven of them were living-donor kidney transplant recipients, and the mean age at time of transplant was 56.6 ± 11.99 years. The mean post-transplant follow-up was 76.75 ± 56.18 months; the mean dialysis vintage was 46.4 ± 80.35 months, ranging from 8 to 272 months; and the mean serum creatinine (Cr) levels at 3, 6, and 12 months were 1.31 ± 0.47 mg/dL, 1.35 ± 0.51 mg/dL, and 1.34 ± 0.49 mg/dL, respectively. There were 5 graft failures with median graft survival of 101 months. None had recurrence of scleroderma renal crisis. In those without graft failure, the mean serum Cr at last follow-up was 0.96 ± 0.39 mg/dL. Six patients were on angiotensin converting enzyme inhibitors (ACE-I) after transplant. In univariate analysis, none of the factors including, age at time of transplant, dialysis vintage, use of ACE-I, living-donor transplant, cytomegalovirus infection, and serum Cr at 1 year were predictive of graft failure. In our study, we hoped to find outcomes and various factors associated with graft failure in these patients. We found a wide variation in outcomes after kidney transplantation. More studies are needed to assess the factors that may influence the graft survival in this rare disease.

    The British Transplantation Society Guidelines for Living Donor Liver Transplantation was published in July 2015 and is the first national guideline in the field of living donor liver transplantation. The guideline aims to review the evidence relating to the evaluation process of both recipient and donor candidates; address the moral and ethical issues surrounding the procedure; outline the technical aspects of the procedure, including the middle hepatic vein controversy and the "small for size syndrome"; review donor and recipient outcomes and complications including donor mortality; and examine evidence relating to the advantages and disadvantages of living donor liver transplantation. In line with previous guidelines published by the BTS, the guideline has used the Grading of Recommendations Assessment, Development and Evaluation system to rate the strength of evidence and recommendations. This article summarizes the Statements of Recommendation contained in the guideline, which provide a framework for the delivery of living liver donation in the United Kingdom and may be of wide international interest. It is recommended that the full guideline document is consulted for details of the relevant references and evidence base.

    Visceral leishmaniasis (VL) due to Leishmania infantum is an endemic parasitic infection in the Mediterranean area. It most commonly affects immunosuppressed individuals, especially HIV patients and less frequently organ transplant recipients. Renal involvement seems to be frequent and is mostly associated with tubulointerstitial nephritis, as described in autopsy reports. In the 61 cases of renal transplant recipients with VL reported in the literature, renal dysfunction was noted at clinical presentation and was more frequently observed as a complication of antiparasitic therapy. However, no pathological analysis of the allograft lesions was reported. We present the case of a Swiss renal transplant recipient who developed VL after vacations in Spain and Tunisia, complicated by acute parasitic nephritis in the renal allograft 3 months after a well-conducted treatment of liposomal amphotericin B.

    Robotic surgery has enabled surgeons to offer more patients a minimally invasive surgical option in the management of their complex diseases. While renal transplantation is associated with significant improvements in quantity and quality of life for most end-stage renal disease (ESRD) patients, it is also not devoid of its surgical risks and potential morbidities. Robotic-assisted kidney transplantation is a recently described, innovative application of the robotic surgery platform, and early experiences suggest that it is associated with comparable graft function and lower rates of complications. Urinary tract obstruction, though less common than ESRD, can be a serious threat to renal function. Severe ureteric stricture disease can represent a clinically complex problem requiring major reconstructive surgery. Completely intra-corporeal robotic renal auto-transplantation is another innovative application of the robotic surgery platform and represents a significant advancement in urologic surgery. Initial reports of this procedure demonstrate safety, feasibility, and excellent renal function outcomes.

    For a long time, it was considered medical malpractice to neglect the blood group system during transplantation. Because there are far more patients waiting for organs than organs available, a variety of attempts have been made to transplant AB0-incompatible (AB0i) grafts. Improvements in AB0i graft survival rates have been achieved with immunosuppression regimens and plasma treatment procedures. Nevertheless, some grafts are rejected early after AB0i living donor liver transplantation (LDLT) due to antibody mediated rejection or later biliary complications that affect the quality of life. Therefore, the AB0i LDLT is an option only for emergency situations, and it requires careful planning. This review compares the treatment possibilities and their effect on the patients’ graft outcome from 2010 to the present. We compared 11 transplant center regimens and their outcomes. The best improvement, next to plasma treatment procedures, has been reached with the prophylactic use of rituximab more than one week before AB0i LDLT. Unfortunately, no standardized treatment protocols are available. Each center treats its patients with its own scheme. Nevertheless, the transplant results are homogeneous. Due to refined treatment strategies, AB0i LDLT is a feasible option today and almost free of severe complications. PMID:27683633

    The demography in most part of the world is changing with an increasing proportion of elderly persons. This is expected to reflect demography of patients accepted for renal replacement therapy both in the form of dialysis and transplantation. Based on this, the intention of the present review is to collect and describe available data on rates of transplantation with focus on the elderly patients in both Europe and the US. Data were collected from available sources including activity reports from national and supranational registries on uremia, organ procurement, waiting lists, and transplantations. Since 1990 both absolute numbers and proportions of elderly patients starting renal replacement therapy have increased dramatically in both Europe and the US. Although the pattern of changes is similar in Europe and the US, the incidence and prevalence rates for renal replacement therapy in the elderly are 3-4 times higher in the US. In the same period, the rates of renal transplantations in the elderly patient group have increased in both Europe and the US with increased access to the waiting list and to transplantation. Data from the United States Renal Data System on incidence of transplantation document a substantial increase in proportion of elderly transplant recipients (65+ years) from 4.2% in 1990 to 17.2% in 2012 and an increase in proportion of prevalent elderly renal transplant patients from 3.8% in 1992 to 23.3% in 2012. Similar changes have been seen in Europe. Due to these alterations in the demography of the transplant patients in both Europe and the US it is concluded that the elderly transplant patient from being a rare patient has now become a common patient necessitating increased focus on this group in order to optimize treatment results.

    Flow cytometry crossmatching (FCXM) was developed as a more sensitive assay than the standard complement-dependent cytotoxicity crossmatch (CDCXM) for the detection of anti-donor antibodies, that mediate hyperacute rejection and graft loss in the early post-transplant period in renal transplant recipients. The role of FCXM in predicting long-term clinical outcome in renal allograft recipients is unclear. This study examines the role of FCXM in predicting long-term clinical outcome in highly sensitized recipients of cadaveric renal transplants. All patients (n = 100) with peak panel reactive antibody (PRA) levels > 30%, who received cadaveric renal transplants between 1/1/'90 and 12/31/'95 at our institution, were divided into FCXM + and FCXM - groups. The incidence of acute rejection was determined for each group during the first yr after transplant. Graft survival rates at 1, 2, and 3 yr, and creatinine levels were also compared between groups. FCXM + patients experienced a higher incidence of acute rejection during the first yr after transplant (69 vs. 45%), and a higher percentage of FCXM + patients had more than one episode of acute rejection during the first yr after transplant (34 vs. 8%) when compared to FCXM - patients. There was no statistically significant difference in 1-, 2-, or 3-yr graft survival between FCXM + and FCXM - patients (76 vs. 83, 62 vs. 80, 62 vs. 72%, respectively). These results suggest that sensitized FCXM + cadaveric renal transplant recipients have a higher incidence of acute rejection episodes in the first yr after transplant. Given the association of multiple rejection episodes with poor long-term allograft survival, FCXM may be a useful predictor of long-term clinical outcome in this sub-group of renal transplant recipients.

    The evolution of organ transplantation has resulted in extended lifespan as well as better life quality of patients with end-stage diseases, which in turn causes an increased demand for organs. The persistent organ shortage requires a careful reconsideration of potential donors (living or cadaveric) that have current or historical malignancies. Donors with low-grade skin tumors, carcinomas in situ of the uterine cervix, and primary central nervous system (CNS) tumors can be considered as potential donors for recipients dying on wait list longing for organ transplantation. Recently, transplant centers have turned to other types of malignancies including low grade renal cell carcinoma, prostate, ureteral, endometrial and breast cancer, and favorable outcomes have been shown in such innovations. When considering donors with a history of malignancy, general biologic behavior of the tumor type, histology and stage at the time of diagnosis, and the length of disease-free interval should be considered (Transplantation 2002;74(12):1657-1663). With the review of literatures, we illustrate the organ utilization from donors with malignancies all around the world since earlier times and give some suggestions for decision making under the circumstance of whether to choose those marginal donors or not on the basis of reviewed literatures.

    Delayed gastric emptying is a significant postoperative complication of living donor hepatectomy for liver transplantation and may require endoscopic or surgical intervention in severe cases. Although the mechanism of posthepatectomy delayed gastric emptying remains unknown, vagal nerve injury during intraoperative dissection and adhesion formation postoperatively between the stomach and cut liver surface are possible explanations. Here, we present the first reported case of delayed gastric emptying following fully laparoscopic hepatectomy for living donor liver transplantation. Additionally, we also present a case in which symptoms developed after open right hepatectomy, but for which dissection for left hepatectomy was first performed. Through our experience and these two specific cases, we favor a neurovascular etiology for delayed gastric emptying after hepatectomy. PMID:25610698

    Acute kidney injury (AKI) is a very common complication after allogeneic bone marrow transplantation (BMT) and associated with poor prognosis. Generally kidneys are assumed to be no direct target of Graft-versus-Host Disease (GvHD), and renal impairment is often attributed to several other factors occurring in the early phase after BMT. Our study aimed to prove the existence of renal GvHD in a fully MHC-mismatched model of BALB/c mice conditioned and transplanted according to two different intensity protocols. Syngeneically transplanted and untreated animals served as controls. 4 weeks after transplantation, allogeneic animals developed acute GvHD that was more pronounced in the high-intensity protocol (HIP) group than in the low-intensity protocol (LIP) group. Urea and creatinine as classic serum markers of renal function could not verify renal impairment 4 weeks after BMT. Creatinine levels were even reduced as a result of catabolic metabolism and loss of muscle mass due to acute GvHD. Proteinuria, albuminuria, and urinary N-acetyl-beta-Dglucosaminidase (NAG) levels were measured as additional renal markers before and after transplantation. Albuminuria and NAG were only significantly increased after allogeneic transplantation, correlating with disease severity between HIP and LIP animals. Histological investigations of the kidneys showed renal infiltration of T-cells and macrophages with endarteriitis, interstitial nephritis, tubulitis, and glomerulitis. T-cells consisted of CD4+, CD8+, and FoxP3+ cells. Renal expression analysis of allogeneic animals showed increases in indoleamine-2,3 dioxygenase (IDO), different cytokines (TNFα, IFN-γ, IL-1α, IL2, IL-6, and IL-10), and adhesion molecules (ICAM-1 and VCAM-1), resembling findings from other tissues in acute GvHD. In summary, our study supports the entity of renal GvHD with histological features suggestive of cell-mediated renal injury. Albuminuria and urinary NAG levels may serve as early markers of renal

    Prominence of the medullary pyramids at sonography has been considered a sign of renal transplant rejection. A search of the literature reveals no previously published objective assessment of this phenomenon. Medullary pyramids of 67 normal kidneys, 53 nonrejecting transplanted kidneys, and 71 transplanted kidneys in rejection were measured. The area of the pyramid was related to the thickness of the overlying renal cortex by a "medullary pyramid index" (MPI): MPI (formula; see text) The median MPI was 4.17 for normal kidneys, 6.0 for nonrejecting transplanted kidneys, and 7.50 for transplanted kidneys in rejection. The results are significantly different (P = 0.0001) for all possible pairs. Overlap between rejection and nonrejection distributions is, however, considerable, rendering the discriminatory value of an individual observation quite low (0.69). Prominence of the medullary pyramids is therefore of very limited predictive value in the determination of transplant rejection in an individual patient.

    An overweight 56-year-old type II diabetic on peritoneal dialysis (body mass index 35 kg/m(2)) was taking Orlistat for some months up until live-unrelated renal transplantation. Despite oral cyclosporin A (CyA) for 48 hours pretransplantation, it was very difficult to achieve adequate CyA blood levels for the first week postengraftment despite the use of much larger oral CyA doses. After opening his bowels on day 7, and the use of 3 days intravenous CyA, good CyA blood levels were achieved then maintained with conventional oral doses. The authors believe that this case shows important interactions between CyA and Orlistat.

    TT virus (TTV) genogroup 1 infection has an increased prevalence in solid organ transplant recipients. In this study, the presence of TTV in renal transplant recipients was examined by two PCR methods, one capable of detecting most TTV genotypes (UTR-PCR), the other specific to genogroup 1 (N22-PCR). The N22-PCR detected TTV in 57% (53/92) of the renal transplant patients and in 20% (13/66) of the healthy individuals, while the prevalence of TTV with the UTR-PCR was above 90% in both the control and the patient groups. The N22-PCR was used in longitudinal studies of 31 renal transplant recipients, these PCR products were sequenced and aligned. TTV status was not associated with the patients' age at transplantation, male to female ratio and the time lag between kidney transplantation and the TTV test. During the follow-up consistent TTV status was found in 26 patients, while two initially TTV positive patients converted to negative and three initially negative patients converted to positive. The TTV variants varied among the tested patients, but were the same in the consecutive samples of each patient, indicating that TTV infection was persistent in renal transplant recipients and novel infection occurred rarely in the post-transplant period.

    Abstract Background: Acute thrombosis of a transplanted renal artery is a serious vascular complication following renal allograft transplantation, which usually occurs within the first month after transplantation and often results in graft loss. It rarely occurs beyond the first month, except in a rejected kidney or in a kidney with high-grade transplant renal artery stenosis. Result: A 65-year-old male with a history of type 2 diabetes mellitus, hypertension, pulmonary tuberculosis, and end-stage renal disease was previously treated with hemodialysis (HD). He received a kidney transplant and had a well-functioning graft for 2 years. He presented to our emergency department with gastric ulcer bleeding and received treatment involving an endoscopic submucosal epinephrine injection, a proton pump inhibitor, and blood transfusions. Nine days later, he complained of sudden lower abdominal pain and had acute anuric kidney failure. Renal ultrasonography revealed an absence of blood flow to the allograft kidney. Renal artery angiogram demonstrated complete occlusion of the transplanted renal artery. After thrombectomy and percutaneous transluminal angioplasty (PTA) with stent placement, 60% stenosis of the proximal renal artery with distal perfusion was noted. However, his graft function did not improve, and he received HD again. Histopathology of the transplanted kidney revealed ischemic tubular nephropathy with focal infarction without rejection. Conclusion: This is the first case of acute thrombosis of the transplanted renal artery following gastric ulcer bleeding in a patient with a long-term well-functioning graft kidney. PMID:27472705

    We report a cross-sectional study of 54 adult female renal transplant recipients. We measured bone mineral density (BMD) of the lumbar spine, femoral neck, total hip, and mid- and total radius, and 38 patients underwent transiliac crest bone biopsy. Osteopenia was widespread with 31/54 (57%) of patients osteoporotic at one or more sites. Seventeen out of 54 (32%) of the patients had a prevalent low-trauma fracture. There was a clear trend in BMD reduction across spine, hip and midradius, with the predominantly cortical midradial site showing the greatest loss. We found no relationship between BMD and body mass index, parathyroid hormone (PTH), dose of immunosuppressant, years since transplantation, age at menopause, or years since menopause. Histologically, abnormal biopsies could be classified into three categories: hyperparathyroid (n = 20), adynamic (n = 14), and osteomalacic (n = 2). Mean PTH was lower (p = NS) and mean cumulative prednisolone dose was higher (p = 0.04) in the adynamic group compared with the hyperparathyroid group, but because of overlap between groups neither was an effective discriminator of histology. We suggest that bone biopsy is indicated in these patients to direct appropriate treatment. At the cellular level, there were significant negative correlations between osteoclast function (eroded surface, r = 0.47, p = 0.003) and osteoblast numbers (osteoblast surface, r = -0.40, p = 0.01) and cumulative exposure to prednisolone. We postulate that suppression of osteoblast function by prednisolone with unopposed bone resorption may result in relative hypercalcaemia and low PTH. This progressive reduction in bone turnover may promote or prolong the adynamic state.

    This summary of the NAPRTCS 2006 Annual Report of the Transplant Registry highlights the significant impact the registry has had in advancing knowledge in pediatric renal transplantation worldwide. This cooperative group has collected clinical information on children undergoing a renal transplantation since 1987 and now includes over 150 participating medical centers in the USA, Canada, Mexico, and Costa Rica. Currently, the NAPRTCS transplant registry includes information on 9837 renal transplants in 8990 patients (NAPRTCS 2006 Annual Report). Since the first data analysis in 1989, NAPRTCS reports have documented marked improvements in outcome after renal transplantation in addition to identifying factors associated with both favorable and poor outcomes. The registry has served to document and influence practice patterns, clinical outcomes, and changing trends in renal transplantation.

  10. Living donor liver transplantation for hepatocellular carcinoma achieves better outcomes

    2016-01-01

    Liver transplantation (LT) for hepatocellular carcinoma (HCC) at Kaohsiung Chang Gung Memorial Hospital mainly relies on live donor LT (LDLT). Owing to taking the risk of LD, we are obligated to adopt strict selection criteria for HCC patients and optimize the pre-transplant conditions to ensure a high disease-free survival similar to those without HCC, even better than deceased donor LT (DDLT). Better outcomes are attributed to excellent surgical results and optimal patient selection. The hospital mortality of primary and salvage LDLT are lower than 2% in our center. Although Taiwan Health Insurance Policy extended the Milan to University of California, San Francisco (UCSF) criteria in 2006, selection criteria will not be consolidated to take into account only by the morphologic size/number of tumors but also by their biology. The criteria are divided into modifiable image morphology, alpha fetoprotein (AFP), and positron emission tomography (PET) scan with standard uptake value (SUV) and unmodifiable unfavorable pathology such as HCC combined with cholangiocarcinoma (CC), sarcomatoid type, and poor differentiation. Downstaging therapy is necessary for HCC patients beyond criteria to fit all modifiable standards. The upper limit of downstaging treatment seems to be extended by more effective drug eluting transarterial chemoembolization in cases without absolute contraindications. In contrast, the pitfall of unmodifiable tumor pathology should be excluded by the findings of pretransplant core biopsy/resection if possible. More recently, achieving complete tumor necrosis in explanted liver could almost predict no recurrence after transplant. Necrotizing therapy is advised if possible before transplant even the tumor status within criteria to minimize the possibility of tumor recurrence. LDLT with low surgical mortality in experienced centers provides the opportunities of optimizing the pre-transplant tumor conditions and timing of transplant to achieve better

Liver transplantation (LT) began in Taiwan in 1984, and living donor liver transplantation (LDLT) in 1994. Education and collaboration between physicians on a national and international scale were important factors in the development of transplantation in East Asia. Technical innovations in donor hepatectomy, vascular and biliary reconstruction, and interventional radiology, perioperative management of transplant patients and development of associated specialties have enabled achievement of excellent results after both adult and pediatric LDLT. The establishment of rigorous protocols to withstand strict medico-legal scrutiny, combined with technical excellence has contributed to excellent surgical outcomes. The socioeconomic development of Taiwan and the first nationwide hepatitis B vaccination program in the world have also contributed to the decrease in disease burden and improvement of quality of healthcare. This article examines the factors enabling the development of LT in Taiwan, the innovations that have contributed to excellent outcomes, and indicates the future prospects of LDLT in Taiwan.

    Renal transplantation is the treatment of choice for the patients with end-stage renal failure. Genetic factors, among others, can influence variability in response to immunosuppressive drugs. Nowadays, due to restrictive health resources, the question arises whether routine pharmacogenetic analyses should be done in the renal transplant recipients or not. The aim of this literature review was to present the up-to-date information considering the economic feasibility of pharmacogenetic testing in patients subjected to renal transplantation. The organization United Network for Organ Sharing in the US estimated that total costs per renal transplant concerning these analyses were $334,300 in 2014. Pharmacogenetic testing prior to treatment initiation could be helpful to predict and assess treatment response and the risks for adverse drug reactions. This kind of testing before treatment initiation seems to be one of the most promising applications of pharmacokinetics. Although pharmacogenetic tests were found to be a cost-effective or cost-saving strategy in many cases, some authors represent another opinion. However, if the real costs of renal transplantation are recognized, the application of these tests in the standard daily practice could be considered more realistic, which additionally emphasizes the importance of future studies assessing their cost effectiveness.

    Sirolimus and tacrolimus are the major immunosuppressants for renal transplantation. Several studies have compared these 2 drugs, but the outcomes were not consistent. The aim of this study was to evaluate the efficacy, safety, and pharmacoeconomics of sirolimus and tacrolimus in the treatment of renal transplantation and provide evidence for the selection of essential drugs. Trials were identified through a computerized literature search of PubMed, EMBASE, Cochrane controlled trials register, Cochrane Renal Group Specialized Register of randomized controlled trials, and Chinese Biomedical database. Two independent reviewers assessed trials for eligibility and quality and then extracted data. Data were extracted for patient and graft mortality, acute rejection (AR), and adverse events. Dichotomous outcomes were reported as relative risk with 95% confidence intervals. A decision tree model was populated with data from a literature review and used to estimate costs and QALYs gained and incremental cost-effectiveness. Altogether, 1189 patients from 8 randomized controlled trials were included. The results of our analysis were that tacrolimus reduced the risks after renal transplantation of AR and patient withdrawn. Nevertheless, tacrolimus increased the risk of infection. Pharmacoeconomic analysis showed that tacrolimus represented a more cost-effective treatment than does cyclosporine for the prevention of adverse events after renal transplant. Tacrolimus is an effective and safe immunosuppressive agent, and it may be more cost-effective than cyclosporine for the primary prevention of AR in renal transplant recipients. However, it should be noted that such superiority was reversal when the cost of sirolimus and tacrolimus changed.

    Hyperlipidemia and hypertension, two major risk factors for accelerated atherosclerosis, undoubtedly contribute to the excessive cardiovascular morbidity and mortality experienced by renal transplant recipients. The present survey of posttransplant hyperlipidemia in 500 cyclosporine-treated patients documented a 37.6% incidence of hypercholesterolemia, which occurred within 6 months posttransplant in 82% of patients. An etiologic relation to corticosteroid therapy was suggested by the strong correlation between prednisone doses and cholesterol levels, by the reduced cholesterol levels in patients undergoing steroid withdrawal, and by the reduction in hypercholesterolemia to 13% by 3 years posttransplant when steroid doses were less than 10 mg daily. Hypertriglyceridemia, which was present in 14.7% of the patients, was more severe under CsA-prednisone compared with azathioprine-prednisone therapy. Hypertriglyceridemia, which occurred later in the posttransplant course than hypercholesterolemia, strongly correlated with an excessive percent relative weight and elevated serum creatinine but not with steroid or CsA doses. Increasing age, diabetes mellitus, beta-blockers and nephrotic syndrome contribute to posttransplant hyperlipidemia in the CsA-Pred era as they did in the azathioprine era of immunosuppression.

    Previous reports indicate that In-111 platelet scintigraphy (IPS) is a reliable test for the early diagnosis of acute post-operative renal transplant rejection (TR). However, the recent introduction of cyclosporin for post-transplantation immunosuppression requires that the diagnostic efficacy of IPS once again be established. Therefore, a prospective IPS study of 73 post-operative renal transplant recipients was conducted. Fourty-nine patients received cyclosporin and 24 patients did not receive this drug. Between these two patient groups, there were no significant differences in the diagnostic sensitivities (0.86 vs 0.80) and specificities (0.93 vs 0.84) with which TR was identified. We conclude that during the first two weeks following renal transplantation the cyclosporin treatment regimen used at our institution does not limit the reliability of IPS as a test for TR.

  17. The challenge of doing what is right in renal transplantation: balancing equity and utility.

    Arguably the greatest challenge faced by the transplant community is the disparity between the number of persons waiting for a solid organ transplant and the finite supply of donor organs. For renal transplantation the gap between supply and demand has risen annually reflecting the increasing prevalence of end-stage renal disease versus the relatively static deceased donor organ pool. Maximising the benefit from this scarce resource raises difficult ethical issues. For most patients on dialysis therapy a successful transplant offers improved quality and quantity of life, but the absolute gain in survival provided by a donated organ varies greatly depending on recipient factors such as age and co-morbid illnesses. The philosophies of equity (a fair opportunity for everyone in need to receive a transplant) and utility (optimal profit from each organ) are often competing. National allocation schemes and local policies regarding assessment of potential recipients and acceptance of organs are designed to balance these ethical principles in a standardized and socially acceptable manner. The ongoing debate surrounding these issues and modifications to such policies reflect the evolving clinical picture of renal transplantation and the challenge in maintaining equipoise between renal transplant utility and equity.

    Background Whether vascular multiplicity should be considered as contraindication and therefore ‘extended donor criterion’ is still under debate. Methods Data from all live kidney donors from 2006–2013 (n = 951) was retrospectively reviewed. Vascular anatomy as imaged by MRA, CTA or other modalities was compared with intraoperative findings. Furthermore, the influence of vascular multiplicity on outcome of donors and recipients was studied. Results In 237 out of 951 donors (25%), vascular multiplicity was present. CTA had the highest accuracy levels regarding vascular anatomy assessment. Regarding outcome of donors with vascular multiplicity, warm ischemia time (WIT) and skin-to-skin time were significantly longer if arterial multiplicity (AM) was present (5.1 vs. 4.0 mins and 202 vs. 178 mins). Skin-to-skin time was significantly longer, and complication rates were higher in donors with venous multiplicity (203 vs. 180 mins and 17.2% vs. 8.4%). Outcome of renal transplant recipients showed a significantly increased WIT (30 vs. 26.7 minutes), higher rate of DGF (13.9% vs. 6.9%) and lower rate of BPAR (6.9% vs. 13.9%) in patients receiving a kidney with AM compared to kidneys with singular anatomy. Conclusions We conclude that vascular multiplicity should not be a contra-indication, since it has little impact on clinical outcome in the donor as well as in renal transplant recipients.

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

    Background Hispanic Americans face disparities in access to kidney transplantation, particularly living donor kidney transplantation (LDKT). This study compared characteristics of LDKT recipients before and after implementing the Hispanic Kidney Transplant Program (HKTP) at Northwestern Medicines (NM) and other centers. Methods The NM HKTP, initiated in December 2006, delivers culturally and linguistically competent and congruent care. Program-specific data were used to compare the mean ratios of Hispanic to non-Hispanic white LDKTs between pre-HKTP (2001-2006) and post-HKTP (2008-2013), and to compare the characteristics of NM's adult LDKT patients between pre-HKTP and post-HKTP. The same ratio was calculated for transplant centers in regions with a significant Hispanic population (≥25%) and performing in the top tertile of total LDKT volume in the pre-HKTP period. The number of Hispanic and non-Hispanic white patients added to the waiting list were compared between pre-HKTP (2001-2006) and post-HKTP (2008-2013) as a proxy for increased patient referrals and a pathway by which the HKTP may increase LDKTs. Results The ratio of Hispanic to non-Hispanic white LDKTs significantly increased by 70% after the implementation of NM's HKTP (pre-HKTP mean = 0.20, post-HKTP mean = 0.34; P= 0.001). None of the other transplant centers experienced a similar increase in their ratio of Hispanic to non-Hispanic white LDKTs. The NM waiting list additions grew by 91% among Hispanics, but grew only 4% for non-Hispanic whites. Conclusions These data suggest that the development and implementation of a culturally congruent transplant program can positively affect Hispanic LDKT and thereby reduce Hispanics disparities in LDKT rates. Further studies are needed to prospectively evaluate the generalizability of implementing such culturally competent interventions at other transplant programs. PMID:27500229

    The increase in cancer incidence in renal transplant recipients is a well recognized fact, which has been related to post-transplant immunosuppressive therapy. Solid tumors, skin cancer and non-Hodgkin's lymphomas account for most of the neoplasms in these patients, whereas chronic myeloproliferative disorders are infrequent. A patient is reported who developed chronic myelogenous leukemia (CML) six years after renal transplantation, which was followed by immunosuppressive with azathioprine, and the published data on such an association are reviewed. In all 10 cases reported azathioprine had been administered after transplantation. The amount and type of post-transplant immunosuppressive therapy seems to be the most important risk factor for the development of secondary CML in these patients, since no cases of CML in patients receiving cyclosporine A have been reported.

  2. Simultaneous pancreas and kidney transplantation in diabetes with renal failure: the gold standard?

    Simultaneous Pancreas and Kidney (SPK) transplantation in the 21st century is a proven therapeutic intervention for diabetes with renal failure. Although it is a major invasive procedure, successful transplantation leads to an overall improvement in the quality of life of the recipient, freedom from insulin and dialysis, along with stabilisation and improvement in several of the multi-system complications associated with long-term diabetes. It is also associated with improved longevity when compared to diabetics who have had a kidney transplant alone. The combined transplant could be considered a curative procedure albeit at the expense of long-term immunosuppression. In essence, successful SPK transplantation may be considered the gold standard against which all other therapeutic interventions may be measured in diabetes with end-stage renal failure.

    Incomplete resolution of abnormalities of mineral metabolism associated with CRF results in the relatively high prevalence of ROD in pediatric kidney recipients. This non-randomized, cross-sectional, and analytic-descriptive study on bone density, vitamin D, and mineral metabolism was performed in 57 children and adolescents who had received a total of 60 renal allografts in Shiraz, Iran. The height and weight of the patients were measured; their serum calcium (Ca), phosphorus (P), Alk-P, PTH, 25(OH)-vitamin D(3), BUN, creatinine, and electrolyte levels were analyzed, and a complete blood count was performed. In addition, standard radiologic bone assessments, which included conventional left hand-wrist radiography and bone mineral densitometry by the DXA technique, were carried out. Special pediatric software was used for age-related interpretation of the Z-scores of BMD. SPSS(®) software (version 15) was used for statistical analyses. We studied 57 patients (27 males [47.4%]) with a mean age of 18.7 ± 4.25 (9-27) yr and a mean age at transplantation of 13.1 ± 3.46 (4.5-20) yr. They had a post-transplantation follow-up of 67.1 ± 33.8 (6-132) months, and all had well-functioning allografts at enrollment. The mean height age of the patients was 11.9 ± 1.8 (6-15.5), and the mean bone age was 15.6 ± 3.3 (7-19) yr, which corresponded to mean height-age and bone-age retardations of 5.7 ± 2.3 (0.5-10.5) and 1.22 ± 1.47 (0-7) yr, respectively. Hyperphosphatemia and hypercalcemia were each found in nine patients (15.8%), hypophosphatemia in five (8.8%), and hypocalcemia in none of the patients. Seven out of 57 patients (12.3%) had a (Ca×P) product of more than 55 mg(2)/dL(2). Hyperparathyroidism was found in 27 (47.3%) and vitamin D(3) deficiency in four (7%) of the cases. The serum level of Alk-P was higher than the age-related normal range in 20 patients (35%). Left hand-wrist radiography showed no radiologic sign of ROD in any patient. The mean BMD Z-score was

    Socioeconomic status-related factors have been associated with access to kidney transplantation, yet few studies have investigated both individual income and education as determinates of access to kidney transplantation. Therefore, this study aims to explore the effects of both individual income and education on access to kidney transplantation, controlling for both medical and non-medical factors. We linked the Swedish Renal Register to national registers for a sample of adult patients who started Renal Replacement Therapy (RRT) in Sweden between 1 January 1995, and 31 December 2013. Using uni- and multivariate logistic models, we studied the association between pre-RRT income and education and likelihood of receiving kidney transplantation. For non-pre-emptive transplantation patients, we also used multivariate Cox proportional hazards regression analysis to assess the association between treatment and socioeconomic factors. Among the 16,215 patients in the sample, 27% had received kidney transplantation by the end of 2013. After adjusting for covariates, the highest income group had more than three times the chance of accessing kidney transplantation compared with patients in the lowest income group (odds ratio (OR): 3.22; 95% confidence interval (CI): 2.73–3.80). Patients with college education had more than three times higher chance of access to kidney transplantation compared with patients with mandatory education (OR: 3.18; 95% CI: 2.77–3.66). Neither living in the county of the transplantation center nor gender was shown to have any effect on the likelihood of receiving kidney transplantation. For non-pre-emptive transplantation patients, the results from Cox models were similar with what we got from logistic models. Sensitive analyses showed that results were not sensitive to different conditions. Overall, socioeconomic status-related inequities exist in access to kidney transplantation in Sweden. Additional studies are needed to explore the possible

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

    Renal ischemia reperfusion (IR)-injury induces activation of innate immune response which sustains renal injury and contributes to the development of delayed graft function (DGF). Triggering receptor expressed on myeloid cells-1 (TREM-1) is a pro-inflammatory evolutionary conserved pattern recognition receptor expressed on a variety of innate immune cells. TREM-1 expression increases following acute and chronic renal injury. However, the function of TREM-1 in renal IR is still unclear. Here, we investigated expression and function of TREM-1 in a murine model of renal IR using different TREM-1 inhibitors: LP17, LR12 and TREM-1 fusion protein. In a human study, we analyzed the association of non-synonymous single nucleotide variants in the TREM1 gene in a cohort comprising 1263 matching donors and recipients with post-transplant outcomes, including DGF. Our findings demonstrated that, following murine IR, renal TREM-1 expression increased due to the influx of Trem1 mRNA expressing cells detected by in situ hybridization. However, TREM-1 interventions by means of LP17, LR12 and TREM-1 fusion protein did not ameliorate IR-induced injury. In the human renal transplant cohort, donor and recipient TREM1 gene variant p.Thr25Ser was not associated with DGF, nor with biopsy-proven rejection or death-censored graft failure. We conclude that TREM-1 does not play a major role during experimental renal IR and after kidney transplantation. PMID:27928159

    Function of the parathyroid gland was evaluated in children with renal insufficiency prior to and after imitation of hemodialysis, and again following renal transplantation. Serum levels of immunoreactive parathyroid hormone responded appropriately to increases or decreases of serum calcium concentrations in the three groups. Functional and histologic studies in the children with renal insufficiency demonstrated the cause of their elevated circulating levels of iPTH to be diffuse parathyroid hyperplasia. During hemodialysis, the serum concentration of calcium rose and that of iPTH decreased, when the calcium gradient between the dialysate and the blood favored movement of calcium into the body. During treatment with prednisolone (20 mg/kg intravenously) for reversal of renal transplant rejection, the serum concentration of calcium decreased and that of iPTH increased. These observations suggest that autonomy of the parathyroid gland rarely occurs in children with renal insufficiency, and that hemodialysis using a dialysate with a high concentration of calcium might assist in retarding the progression of renal osteodystrophy. Furthermore, if hyperparathyroidism contributes in part to growth failure in children with chronic renal disease, steroid-induced changes in cirulating iPTH following renal transplantation may inhibit growth.

    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 <45 per year during 2009-2011. There was a parallel increase in the number of kidney transplantations from living donors, from a median of 56 transplants per year in 2006-2008 to 78 per year in 2008-2011, with a peak of 117 transplants in 2011. In conclusion, the Israel Transplant Law has dramatically affected kidney transplantation practices in Israel by reducing transplantation tourism and increasing living-donor kidney transplantations.

    Acquired central diabetes insipidus (CDI) often occurs abruptly after a cranial event causing hypothalamic or pituitary damage. We present a case of a patient with pre-existing and clinically unapparent CDI which was unmasked after renal transplantation. A 60 year old woman with end-stage renal failure due to autosomal dominant polycystic kidney disease (ADPKD) underwent renal transplantation. She was noted to be markedly polyuric and polydipsic after the transplant. A fluid deprivation test was unequivocally positive for CDI, and desmopressin treatment resulted in immediate symptom relief. Neuroimaging revealed a midline defect in the region of the hypothalamus. She had a history of an intracerebral aneurysm that had ruptured, requiring extensive neurosurgery many years previously. This case demonstrates a rare instance of pre-existing but clinically unapparent CDI unmasked by renal transplantation. It is likely that renal failure due to ADPKD disguised her CDI prior to transplantation. A previous intracerebral insult from an aneurysmal bleed is the likely cause of her vasopressin deficiency.

    This study was initiated to assess the temporal trends of renal function, and define risk factors associated with worsening renal function in pediatric heart transplant recipients in the immediate post-operative period. We performed a single-center retrospective study in children ≤18 yr receiving OHT (1993-2012). The AKIN's validated, three-tiered AKI staging system was used to categorize the degree of WRF. One hundred sixty-four patients qualified for inclusion. Forty-seven patients (28%) were classified as having WRF after OHT. Nineteen patients (11%) required dialysis after heart transplantation. There was a sustained and steady improvement in renal function in children following heart transplantation in all age groups, irrespective of underlying disease process. The significant factors associated with risk of WRF included body surface area (OR: 1.89 for 0.5 unit increase, 95% CI: 1.29-2.76, p = 0.001) and use of ECMO prior to and/or after heart transplantation (OR: 3.50, 95% CI: 1.51-8.13, p = 0.004). Use of VAD prior to heart transplantation was not associated with WRF (OR: 0.50, 95% CI: 0.17-1.51, p = 0.22). On the basis of these data, we demonstrate that worsening renal function improves early after orthotopic heart transplantation.

    Daclizumab is an interleukin-2 receptor antagonist which is used for induction therapy in heart transplant patients. It has few side effects and is associated with a low infection rate. Postoperative renal failure after heart transplantation is common and potentially fatal. The administration of calcineurin inhibitors in the postoperative period can aggravate the situation. We report the cases of six patients who underwent heart transplantation and developed acute renal failure in the immediate postoperative period. All were administered daclizumab weekly to avoid the introduction of calcineurin inhibitors and to facilitate recovery of renal function. Calcineurin inhibitors were introduced only once renal function had improved. Renal function recovered in all cases and there was a low complication rate. The administration of repeated doses of daclizumab to patients who experience acute postoperative renal failure after heart transplantation may provide an alternative therapeutic approach that enables calcineurin inhibitors to be avoided and, consequently, renal function to recover.

    In view of the scarcity of organ resources for transplantation, donation by living donors is assuming greater significance now that the technical-surgical problems involved have been solved. In the period between December 1999 and December 2000, 47 potential living liver donors were evaluated and a total of 27 hepatic lobes were transplanted at the Virchow-Klinikum of the Charité Hospital in Berlin. The close personal relationships between recipients and donors gives reason to anticipate high levels of psychosocial pressure during the pre-operative evaluation process; this process consists in part in looking into donor motivation, ambivalence and anxiety. The pre-operative psychometric evaluation of 40 potential living donors indicated that most of the potential donors see themselves as 'super-healthy' and tend to adapt to social expectations, while on the other hand those seven potential living donors not accepted for psychosocial reasons were marked by heightened values for anxious depression and pessimism. The results indicate in most cases a great willingness to donate and on the other hand a high level of obvious psychological pressure for a low number of potential donors. For the latter, both the clinical evaluation interview and the psychometric diagnostics used revealed clear-cut feelings of anxiety and ambivalence towards transplantation.

    Hepcidin is synthesized and secreted by liver cells and has been reported as one of the hormone molecules that regulates iron homeostasis. To determine whether serum level of hepcidin can be used as a biomarker for the evaluation of chronic inflammatory status, iron level and renal function in patients following allograft renal transplantation, serum levels of hepcidin, interleukin (IL)-6, ferritin, serum iron, and renal functions were measured. Sixty patients were included in the current study and were further separated into groups with or without hyperlipidemia. We found that allogeneic kidney transplant recipients with hyperlipidemia have significantly increased serum levels of hepcidin, IL-6, and ferritin. The increased serum hepcidin is positively correlated with serum IL-6 and ferritin as analyzed by single-factor correlation analysis. Multivariant correlation analysis in all specimens further demonstrated that serum hepcidin negatively correlated with glomerular filtration rate, and positively correlated with serum total cholesterol, triglycerides, serum ferritin, and IL-6. Our study demonstrated that serum level of hepcidin after allogeneic kidney transplantation not only reflects the status of chronic inflammation but can also indicate changes in renal function. Thus, hepcidin has the potential to be used as a promising marker for the detection and monitoring of the status of chronic inflammation, hyperlipidemia, and renal function in patients following allograft renal transplantation.

    Hepcidin is a small peptide with a critical role in cellular iron homeostasis, as it regulates utilization of stored iron and antimicrobial defense in inflammation (bacterial and fungal). Since it was isolated in 2000, and especially in the last decade, numerous studies aimed to evaluate the clinical use of plasma and urine hepcidin as a marker of anemia, especially anemia of chronic disease and post-transplant anemia (PTA). Hepcidin regulation is delicately tuned by two inflammatory pathways activated by interleukin-6 (IL-6) and bone morphogenic proteins (BMPs) and iron regulated pathway sensitive to circulating transferin-iron (TR-Fe) complex. BMP-mediated pathway and TR-Fe sensitive pathway seem to be connected by hemojuveline, a BMP co-factor that interacts with transferine receptor 2 (TRF2) in cases of high TR-Fe circulatory concentration. In addition to these regulatory mechanisms other regulators and signaling pathways are being extensively researched. 
Hepcidin has been identified as an important contributor to morbidity and mortality in end stage renal disease (ESRD) but no such association has jet been found in case of PTA. However, there is an association between higher doses of erythropoiesis-stimulating agents (ESA) and mortality in the posttransplant period and the assumption that hepcidin might play a role in ESA resistance in PTA. Thus the review's main goal was to summarize papers published on the association of hepcidin with PTA, give up-to-date information on hepcidin regulation and on potential therapeutics that optimize hepcidin regulation. We also compared the performances of tests for hepcidin determination and reviewed research on immunosuppressants' (IS) effect on hepcidin concentration.

    Introduction The aim of this study was to evaluate the incidence and types of neurological complications (NCs) and associated factors in renal transplantation (RT) patients. Methods Three hundred and forty-four patients who had RT performed at our institution between January 2005 and July 2014 were retrospectively evaluated. Results File records of the patients revealed 19 who experienced a total of 22 episodes of NCs, of whom three had more than one episode. The mean age of 19 patients included in the study, of whom eight were female, was 37.52±13.08 (range, 18–65) years. NCs were classified into central or peripheral depending on the location of involvement of the central nervous system (CNS). CNS involvement was found in 16 (84.2%) of the 19 patients. Tremor (36.8%) was the most common CNS complication in these patients. Encephalopathy, generalized tonic–clonic seizures, and status epilepticus were observed in two patients (10.5%). Delirium and dementia were observed in one patient (5.2%). Headache was experienced by one patient, and agitated depression was observed in one patient. Six patients (26.3%) had the peripheral nervous system involvement. One patient had the numbness of hands with normal electromyography findings, and four patients had polyneuropathy. In one patient, lumbar plexopathy was observed. Seventeen of the 22 NCs were considered to be caused by immunosuppressive agents. Each incidence of amyloidosis, infection, septic emboli, and hypoglycemia caused a neurological episode. The etiology of one episode was unknown. Conclusion Different neurological disorders can be seen after RT, and most of them are caused by immunosuppressive drugs. NCs seen after RT can be treated by decreasing the dose or changing the immunosuppressive drug.

    This case represents the need for total teamwork in the assessment, diagnosis, and treatment of an immunosuppressed patient with a viral syndrome. One of the most striking features of this case study is the importance of a thorough history of current events and exposures in determining the list of potential diagnoses. The systematic process of laboratory evaluations to determine viral activity in an immunosuppressed patient is paramount in identifying the actual culprit responsible for the myriad of clinical symptoms at presentation. The symptomatology would guide one to the common viruses, but the travel history was the clue to testing for an uncommon etiology. The input from family members relating to the progression of mental status changes was also an important part of the current medical history. Along with supportive treatment, the patient was also given a course of interferon alpha as part of an experimental protocol. The support of the family during this decision-making process was an important function of the entire team. The patient was unable to participate in this decision and the family required a great deal of discussion regarding the pros and cons of their decision. For this patient, the outcomes were excellent. He has stable renal function, has no neurologic residual, and is back to his baseline physically and psychologically. An important recommendation based on this case is to provide educational materials to all transplant patients on viral illnesses. Topics covered should include modes of transmission, symptomatology, and the consequences of the illness. The CDC has excellent materials on West Nile Virus that can be downloaded and provided to all patients. In addition, a thorough medical history should always be obtained including possible exposures and recent travel.

    Obesity and hypertension frequently complicate renal transplantation (RTxp). The objective was to assess relations among obesity, hypertension, and glucocorticoids in pediatric RTxp recipients. A retrospective cohort study was carried out in 141 RTxp recipients, 2-21 years of age, with >or=12 months of follow-up. Body mass index Z-score (BMI-Z), systolic and diastolic blood pressure Z-scores (SBP-Z and DBP-Z), and medications at 1, 3, 6, and 12 months and annually thereafter were recorded. Quasi-least squares regression analysis was used. The prevalence of obesity (BMI>or=95th percentile) increased from 13% at baseline to >30% from 3 months onward. Greater glucocorticoid exposure (mg/kg/day) was associated with greater increases in BMI-Z (p<0.001). This association was greater in males, younger recipients, and those with lower baseline BMI-Z (all interactions p<0.02). The prevalence of systolic hypertension (SBP>or=95th percentile) was 73% at 1 month and >or=40% at all follow-up visits. Greater glucocorticoid exposure (p<0.001) and increases in BMI-Z (p=0.005) were independent determinants of SBP-Z over time. Cyclosporine (versus tacrolimus) was independently associated with greater SBP-Z and DBP-Z (p=0.001). Sustained obesity and hypertension frequently complicated pediatric RTxp. Obesity was an independent determinant of systolic hypertension. Strategies are needed to prevent obesity and its impact on hypertension, cardiovascular disease, and allograft survival.

    Biliary complications are common after living donor liver transplant (LDLT) although with advancements in surgical understanding and techniques, the incidence is decreasing. Biliary strictures are more common than leaks. Endoscopic retrograde cholangiopancreatography (ERCP) is the first line modality of treatment of post LDLT biliary strictures with a technical success rate of 75%-80%. Most of ERCP failures are successfully treated by percutaneous transhepatic biliary drainage (PTBD) and rendezvous technique. A minority of patients may require surgical correction. ERCP for these strictures is technically more challenging than routine as well post deceased donor strictures. Biliary strictures may increase the morbidity of a liver transplant recipient, but the mortality is similar to those with or without strictures. Post transplant strictures are short segment and soft, requiring only a few session of ERCP before complete dilatation. Long-term outcome of patients with biliary stricture is similar to those without stricture. With the introduction of new generation cholangioscopes, ERCP success rate may increase, obviating the need for PTBD and surgery in these patients. PMID:27057304

    2016-01-01

    A promising strategy for increasing living donor kidney transplant (LDKT) rates is improving education about living donation for both prospective kidney transplant recipients and living donors to help overcome the proven knowledge, psychological, and socioeconomic barriers to LDKT. A recent Consensus Conference on Best Practices in Live Kidney Donation recommended that comprehensive LDKT education be made available to patients at all stages of chronic kidney disease (CKD). However, in considering how to implement this recommendation across different healthcare learning environments, the current lack of available guidance regarding how to design, deliver, and measure the efficacy of LDKT education programs is notable. In the current article, we provide an overview of how one behavior change theory, the Transtheoretical Model of Behavior Change, can guide the delivery of LDKT education for patients at various stages of CKD and readiness for LDKT. We also discuss the importance of creating educational programs for both potential kidney transplant recipients and living donors, and identify key priorities for educational research to reduce racial disparities in LDKT and increase LDKT rates.

    Live kidney transplantation (LKT) is underused by patients with end-stage renal disease. Easily implementable and effective interventions to improve patients' early consideration of LKT are needed. The Talking About Live Kidney Donation (TALK) social worker intervention (SWI) improved consideration and pursuit of LKT among patients with progressive chronic kidney disease in a recent randomized controlled trial: Patients and their families were invited to meet twice with a social worker to discuss their self-identified barriers to seeking LKT and to identify solutions to barriers. The authors audio recorded and transcribed all social worker visits to assess implementation of the TALK SWI and its acceptability to patients and families. The study social worker adhered to the TALK SWI protocol more than 90 percent of the time. Patients and families discussed medical (for example, long-term risks of transplant), psychological (for example, patients' denial of the severity of their disease), and economic (for example, impact of donation on family finances) concerns regarding LKT. Most patients and families felt that the intervention was helpful. Consistently high adherence to the TALK SWI protocol and acceptability of the intervention among patients and families suggest that the TALK SWI can be feasibly implemented in clinical practice.

    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.

    This study evaluated older renal transplant recipients' perceptions of electronic medication monitoring and the influence of these perceptions on medication adherence. A sample of 73 older adult renal transplant recipients who used the Medication Event Monitoring System (MEMS(®)) TrackCaps for 12 months provided their perceptions of device use. Participants perceived that the MEMS had a neutral effect on their medication-taking routine (65%), believed the MEMS was practical (56%), and could not describe any instances in which using the MEMS was difficult (56%). No significant difference in medication adherence was found between those who perceived the MEMS's influence negatively/neutrally and those who perceived the MEMS positively (p = 0.22). Medication adherence data from older adult renal transplant recipients can be used regardless of their perceptions of the MEMS's influence on their medication taking without biasing medication adherence data.

    Magnetic resonance imaging (MRI) was compared with radionuclide scintigraphy (RNS) in 16 patients with renal transplants undergoing renal failure to determine which modality could best discriminate between rejection, acute tubular necrosis (ATN), and cyclosporin nephrotoxicity (CN). Although all rejecting transplants had reduced corticomedullary differentiation (CMD) on T1-weighted MR images, four of five cases of ATN had appearances that could not be distinguished from rejection. A normal CMD suggests nonrejection, but diminished CMD is nonspecific. Tc-99m DTPA/I-131 hippuran RNS was superior to MRI in differentiating rejection from ATN. Although ATN and CN have similar RNS patterns, this distinction can usually be made based on the clinical time course. Other potential uses of MRI in the evaluation of the renal transplants are discussed.

    Sodium polystyrene sulfonate (SPS) is a medication commonly used for the treatment of hyperkalemia. There have been many cases of colonic necrosis and perforation associated with administration of SPS. There are very few such cases reported in renal transplant patients. We present a case of renal transplant recipient who developed cecal perforation after a single oral dose of SPS. She had no signs or symptoms suggestive of intestinal perforation and was incidentally diagnosed with it on abdominal imaging performed to find cause of acute blood loss anemia. This case underlines the importance of recognizing this severe and potentially life-threatening complication associated with SPS. The clinicians should also consider renal/solid organ transplant and immunosuppression as potential risk factors.

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

    Voided urine is routinely collected from renal transplant patients to screen for polyomavirus. In rare cases, atypical lymphoid cells can be detected in voided urine and raise the suspicion of post-transplant lymphoproliferative disorder (PTLD). However, further immunohistochemistry of the cell block and flow cytometry is frequently limited by the low cellularity and poor preservation of voided urine. Therefore, PTLD of the renal allograft is usually diagnosed from tissue biopsy or nephrectomy specimens. Herein, we report a rare case of atypical cells in a voided urine cytology specimen from a kidney transplant recipient. Needle core biopsy of the renal allograft showed monomorphic PTLD. Diagn.

We report here the case of an Australian renal transplant patient who presented with disseminated P. marneffei infection shortly after a 10-day holiday to Vietnam, and review all previously published cases of penicilliosis associated with renal transplantation. This is the first reported case, to our knowledge, of P. marneffei infection in an SOT recipient acquired during travel to an endemic country, and highlights the importance of an accurate travel history when opportunistic infection is suspected, as well as giving appropriate health advice to transplant patients who travel.

    Previously, patients with chronic renal failure and major congenital anomalies of the lower urinary tract (often with urinary diversion) were thought to be poor candidates for renal transplantation. Pre-transplant evaluation and possible urinary reconstruction are essential in these patients to achieve successful renal transplantation. Ten patients, including 7 adults, presented with congenital anomalies of the lower urinary tract that were responsible for renal failure. Percutaneous suprapubic cystostomy aided in the assessment of bladder function. Undiagnosed posterior urethral valves were found in 2 adults. Patients with exstrophy, neurogenic bladder or a contracted bladder (with augmentation cystoplasty) had urinary drainage into the bladder at the time of renal transplantation. Sometimes an imperfect bladder can be used for urinary drainage with transplantation but, otherwise, intestinal conduits are still a viable alternative.

    Introduction: In the past, urological complications after renal transplantation were associated with significant morbidity. With the development and application of endourological procedures, it is now possible to manage these cases with minimally invasive techniques. Materials and Methods: A MEDLINE search for articles published in English using key words for the management of urological complications after renal transplantation was undertaken. Forty articles were selected and reviewed. Results: The incidence of urological complications postrenal transplantation was reported to be 2–13%. Ureteric leaks occurred in up to 8.6%, and 55% were managed endourologically. The incidence of lymphocele was as high as 20%, and less that 12% of the cases required treatment. Ureteric stricture was the most common complication, and endourological management was successful in 50–70%. The occurrence of complicated vesicoureteral reflux was 4.5%, and 90% of low-grade reflux cases were successfully treated with deflux injections. Stones and obstructive voiding dysfunction occurred in about 1% of kidney transplant recipients. Conclusion: Minimally invasive techniques have a critical role in the management of urological complications after renal transplantation. Urinary leakage should be managed with complete decompression. Percutaneous drainage should be the first line of treatment for lymphocele that is symptomatic or causing ureteric obstruction. Laparoscopic lymphocele deroofing is successful in aspiration-resistant cases. Deflux is highly successful for the management of complicated low-grade kidney transplant reflux. The principles of stone management in a native solitary kidney are applied to the transplanted kidney. Early identification and treatment of bladder outlet obstruction after renal transplantation can prevent urinary leakage and obstructive uropathy. PMID:27555675

    Strangulated small bowel obstruction is a complication after abdominal surgery, which is rare in renal transplant patients. A 61-year-old man with a strangulated small bowel obstruction underwent renal transplant surgery 7 years before the current admission. He was admitted to our hospital for abdominal pain, nausea, and abdominal distention. An abdominal computed tomography and an ultrasound examination showed intestinal expansion and fluid collection without ascites. His disease was diagnosed as a small bowel obstruction and conservative treatment was begun. However, because of increasing abdominal pain and the collection of ascites, he underwent an emergency laparotomy and was diagnosed as having a strangulated small bowel obstruction. A fibrous cord had formed between the peritoneum (beside the transplanted kidney) and the root of the sigmoid mesocolon, strangulating the looped ileum and causing bleeding necrosis and hemorrhagic ascites collection. The cord and the necrotic ileum were resected, followed by an end-to-end anastomosis. He was discharged 17 days after the surgery in good condition. This is the first reported case of a person having a strangulated small bowel obstruction by a fibrous cord, who did not have a history of laparotomy after renal transplant. A strangulated small bowel obstruction after a renal transplant in a patient with no history of a laparotomy is a rare, but possible postoperative complications should be considered when making a differential diagnosis.

    A 59-yr-old Japanese woman with chronic renal failure caused by IgA nephropathy and antineutrophil cytoplasmic antibody (ANCA)-related glomerulonephritis underwent kidney transplantation from a living unrelated spousal donor. The blood type was compatible, while the human leukocyte antigen (HLA) typing showed a 5/6 locus mismatch. She had become pregnant twice by her donor and had never received blood transfusions. Complement-dependent cytotoxicity cross-match, flow cytometry cross-match (FCXM), and flow panel reactive antibody (PRA) were negative. She initially underwent one week of immunosuppression with mycophenolate mofetil (MMF) and double filtration plasmapheresis (DFPP) immediately before transplantation to reduce the risk of antibody-mediated rejection. Induction therapy consisted of MMF, tacrolimus (TAC), methylprednisolone (MP), and basiliximab. The allograft function was excellent immediately after the operation. However, the urine output and platelet count declined rapidly on post-operative day (POD) 3, while the serum creatinine (sCr) and lactate dehydrogenase levels rose gradually. Subsequently, we could not detect the diastolic arterial flow on Doppler sonography. We diagnosed accelerated acute rejection and treated her with plasma exchange (PEX), intravenous MP pulse therapy, and rituximab. The first episode biopsy on POD 7 revealed acute vascular rejection and acute antibody-mediated rejection (Banff score AMR II). Her urinary excretion increased beginning on POD 13, while the sCr level decreased gradually and reached 0.9 mg/dL on POD 22. In our retrospective analysis, the LAB screen detected donor-specific antibody (DSA). This case suggested that, for successful kidney transplantation in highly sensitized recipients, such as husband-to-wife spousal kidney transplantation with a history of pregnancy, we should keep the risk of AMR in mind, even if the sensitive antibody detection tests are negative.

    Urinary excretion of prostaglandin E2 (PGE2 and F2 alpha (PGF2 alpha) and plasma concentration of arginine vasopressin (AVP) were determined during urinary concentrating and diluting tests in renal transplant recipients and control subjects. During the concentrating test PGE2 and PGF2 alpha remained unchanged in the renal transplant recipients, whereas both PGE2 and PGF2 alpha were significantly reduced in the control subjects. During the diluting test PGE2 and PGF2 alpha increased in both groups but, contrary to PGF2 alpha, PGE2 was significantly higher in all periods in the transplant recipients compared to the controls. However, the prostaglandin excretion rates per kidney were significantly higher in the renal transplant recipients than control subjects, for all periods during both the concentrating and the diluting test. Arginine vasopressin was significantly higher in renal transplant recipients than control subjects during basal conditions, increased to a significantly higher level in the transplant recipients after thirst, but was reduced to the same levels in the two groups during the diluting test. It is concluded that the increased excretion of prostaglandins in renal transplant recipients may be a compensatory phenomenon representing an adaptation to a reduced renal mass in order to maintain adequate renal water excretion. Although a direct relationship between the prostaglandin excretions of PGE2 and PGF2 alpha and AVP does not seem to exist, it is possible that the higher prostaglandin excretion in the renal transplant recipients may be a counterbalancing mechanism to the higher AVP level, which most likely is secondary to a decreased responsiveness to vasopressin of the renal collecting ducts in the transplanted kidney.

    Emphysematous pyelonephritis (EPN) is a rare life-threatening complication of a properly functioning renal allograft leading to potential graft loss and hemodialysis. Currently, no clear management guidelines exist in these clinically challenging immunosuppressed renal transplant recipients. We report a case of a 62-year-old woman who presented with class 4 EPN and was managed with intravenous antibiotics and nephrectomy at our medical center. PMID:28386406

    EBV infection is one of major complications arising in pediatric patients who have undergone renal transplantation. A strong correlation between the grade of immunosuppression and the development of PTLD, one of the most severe EBV-associated diseases, has been recognized. In this study, we monitored the serologic profile in conjunction with peripheral blood EBV-DNA load of 32 children who underwent renal transplantation with tacrolimus as an immunosuppressant. Six patients were EBV-seronegative (EBV-) before the transplantation, and the mean DNA load in the EBV- group was significantly higher than that in the EBV-seropositive (EBV+) group. Seroconversion occurred in five of these patients in a mean period of 22 weeks after the transplantation. The EBV-DNA load in the EBV+ group was maintained at a low level for a year, whereas it increased rapidly to over 1 x 10(5) copies/mL in two patients in the EBV- group three to seven months after the transplantation, which corresponds to the timing of seroconversion, and one of them developed PTLD. These observations suggest that the close monitoring of the EBV-DNA load, along with longitudinal observation of seroconversion, is essential in pediatric renal transplantation, particularly for younger children who are more likely to be EVB-.

    Chronic renal failure leads to many metabolic disorders affecting reproductive function. For men, hypergonadotropic hypogonadism, hyperprolactinemia, spermatic alterations, decreased libido and erectile dysfunction are described. Kidney transplantation improves sperm parameters and hormonal function within 2 years. But sperm alterations may persist with the use of immunosuppressive drugs. In women, hypothalamic-pituitary-ovarian axis dysfunction due to chronic renal failure results in menstrual irregularities, anovulation and infertility. After kidney transplantation, regular menstruations usually start 1 to 12 months after transplantation. Fertility can be restored but luteal insufficiency can persist. Moreover, 4 to 20% of women with renal transplantation suffer from premature ovarian failure syndrome. In some cases, assisted reproductive technologies can be required and imply risks of ovarian hyperstimulation syndrome and must be performed with caution. Pregnancy risks for mother, fetus and transplant are added to assisted reproductive technologies ones. Only 7 authors have described assisted reproductive technologies for patients with kidney transplantation. No cases of haemodialysis patients have been described yet. So, assisted reproductive technologies management requires a multidisciplinary approach with obstetrics, nephrology and reproductive medicine teams' agreement.

    Twenty-eight renal transplantation patients, aged 19-35 years, and 30 healthy women of reproductive age were enrolled into the study. Analyses revealed significant differences between study and control groups' midluteal serum P levels and between study and control groups' serum PRL levels. Although most renal transplantation patients have plasma estrogen and gonadotropin levels similar to those in healthy women, several problems, such as luteal phase defect, might affect transplant recipients.

    As a foreign body, the peritoneal dialysis (PD) catheter represents a potential source of infection, particularly for immunosuppressed renal transplant patients. A retrospective study was therefore undertaken to compare the risks and benefits of our policy of removing PD catheters at 3 months following renal transplant, which was established to allow for early re-initiation of dialysis. Between 1984 and 1990, 43 renal transplants were performed in 35 children who had been receiving maintenance PD. During the 1st month post transplantation, the PD catheter was used in 25 patients (58%) because of acute rejection or primary allograft non-function. Thirty-one patients were eventually discharged with functioning allografts and a PD catheter in place. Of them, 43% developed a catheter-related infection within the next 2 months, a period during which PD was not performed. Potential contributing factors included a history of catheter-related infection prior to transplantation, use of high-dose methylprednisolone to treat acute rejection, and the type of maintenance immunosuppression prescribed; conversely, the use of prophylactic antibiotics appeared to decrease this risk. This study established the potential need for the catheter during the first few weeks, but because of the infection risk of 43% by 3 months post transplantation, our protocol was revised to include catheter removal at the time of hospital discharge. From 1990 until the end of 1992, an additional 19 PD recipients underwent transplantation. In this group, catheters were used during the 1st month in 6 children (32%). Fifteen patients were discharged with a functioning allograft and only 1 patient returned to PD at 12 months post transplant. It is concluded that PD catheters represent an additional source of infection following transplantation and should be removed at the time of hospital discharge, after which the likelihood of use is low.

    Liver transplantation is associated with a significantly increased risk of de novo malignancies, but for renal cancer this risk is less clear. We therefore performed a meta-analysis of published studies to determine whether renal cancer risk in liver transplant recipients (LTRs) was increased. To obtain a more precise conclusion, a systematic search was performed in PubMed and Web of Science databases until June 10, 2015. Standardized incidence ratio (SIR) corresponding 95% confidence interval (CI) were used to estimate risk of renal cancer in LTRs. Heterogeneity test, sensitivity analysis, and publishing bias were also performed. We identified 8 eligible studies and performed a meta-analysis on data of 49,654 LTRs with a total follow-up of 121,514.6 patient-years. The SIR for renal cancer was identified a 3.275-fold higher SIR (95% CI: 1.857-5.777; P < 0.001) in LTRs compared with the general population. This systematic review and meta-analysis demonstrated that the LTRs was associated with a significant increase in the incidence of renal cancer. Such association suggests that yearly routine post-transplant surveillance is need for renal cancer in LTRs.

However, its effect in pubertal patients is still doubtful.

    m-TOR inhibitors (e.g. sirolimus) are well-tolerated immunosuppressants used in renal transplantation for prophylaxis of organ rejection, and are associated with long-term graft survival. Early use of sirolimus is often advocated by clinicians, but this may be associated with a number of side-effects including impaired wound-healing, lymphoceles and delayed graft function. As transplant clinicians with experience in the use of sirolimus, we believe such side-effects can be limited by tailored clinical management. We present recommendations based on published literature and our clinical experience. Furthermore, guidance is provided on sirolimus use during surgery, both at transplantation and for subsequent operations.

    The high incidence of surgical complications following renal transplantation is well known. Urologic complications, however, present some of the most challenging problems to the transplant surgeon. The authors present here a detailed case report of spontaneous (delayed) bladder rupture (SDBR) which occurred 90 days after kidney transplantation in a recipient with cytomegalovirus infection (CMV). Urinary catheter drainage is recommended in preference to surgical intervention for the successful correction of SDBR. It is postulated further that, despite a negative bladder biopsy, CMV may have infiltrated the bladder and contributed to this “spontaneous” bladder wall rupture.

    Renal oncocytomas are benign tumors of the kidneys, which are usually diagnosed postoperatively, due to differential diagnostic problems, from a sample of a renal cell carcinoma. The development of a renal oncocytoma in the native kidneys following renal transplantation is a very rare condition and only a few cases have been published in the world literature. In this case report we present a unique case of bilateral multifocal renal oncocytomas of the native kidneys in a female transplant recipient 6 years after renal transplantation. The patient's postoperative clinical course was uneventful and no local recurrence or distant metastasis has been found so far. The pathology, clinical characteristics, and treatment of renal oncocytomas are also reviewed.

    Arginine vasopressin (AVP) and serum osmolality (Sosm) were determined in plasma before and after a 24-h period of water deprivation in 19 patients with post-renal-transplant hypertension (group I), 14 patients with normal blood pressure after renal transplantation (group II), and 16 healthy control subjects (group III). Urine was collected in four periods of 6 h each for measurement of urine volume (V), urine osmolality (Uosm) and tubular capacity for reabsorption of water (Tc water). AVP and Sosm increased significantly in all groups. The AVP levels were the same in groups I and II, but higher in group I than III both before and after water deprivation. In group II, AVP was higher than in group III only after water deprivation; V was significantly reduced in all groups. In groups I and II, V, Tc water and Uosm were the same. In group III, V was significantly lower than in groups I and II in the last three 6-h periods, and in group III, Tc water was higher in the first 6-h period than in groups I and II. There was a significant positive correlation between AVP and Sosm in all groups. In conclusion, renal water excretion cannot be reduced as rapidly and to the same degree in renal transplant recipients as in control subjects because of a decreased renal capacity for reabsorption of water. The higher AVP level in the transplant recipients may be a compensatory phenomenon for the decreased responsiveness of the renal collecting ducts in the transplanted kidneys. The sensitivity of the osmoreceptors to changes in osmotic stimuli was normal.

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

    In the last two decades posttransplant lymphoproliferative disorders (PTLDs) have been recognized as a complication of organ transplantation with immunosuppression. The reported incidence of PTLDs in renal transplant patients ranges between 0.3-3% (Birkeland et al., Transplantation 1999;67:876-881). In contrast to the reported incidence of PTLDs in post bone marrow transplant, it is 1% in HLA-matched recipients and up to 20% in HLA mismatched T-cell depleted bone marrow recipients (Curtis et al., Blood 1996;94:2208-2216). In cardiac transplant recipients the reported incidence of PTLDs is between 1.8-9.8 (Mihalov et al., Clin Transplant 1996;10:248-255). PTLDs are predominately extranodal. They have varied morphologic patterns and clonality, but almost all are associated with Epstein-Barr virus (EBV). The vast majority are of B cell lineage; only about 10% are of T-cell origin. We report a T-cell anaplastic large cell lymphoma (ALCL) presenting with bilateral pleural effusion and liver involvement in a renal transplant recipient.

    In 2008, 563,294,000 people were living in Latin America (LA), of which 6.6% were older than 65. The region is going through a fast demographic and epidemiologic transition process, in the context of an improvement in socio-economic indices. The Latin American Dialysis and Renal Transplant Registry has collected data since 1991, through an annual survey completed by 20 affiliated National Societies. Renal replacement treatment (RRT) prevalence and incidence showed an increase year by year. The prevalence rate (in all modalities) correlated with the World Bank country classification by income and the epidemiologic transition stage the countries were experiencing. RRT prevalence and kidney transplantation rates correlated significantly with gross national income (GNI), health expenditure in constant dollars (HeExp), % older than 65, life expectancy at birth, and % of the population living in urban settings. Kidney transplantation increased also, year by year, with more than 50% of transplants performed using kidneys from deceased donors. Double transplants were performed in six countries. RRT prevalence and incidence increased in LA, and are associated with indexes reflecting higher and more evenly distributed national wealth (GNI and HeExp), and the stage of demographic and epidemiological transition.

    Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy sampling of enlarged lymph nodes is increasingly used to diagnose metastatic tumors, especially of the gastrointestinal tract and the lungs. Herein, we describe the diagnosis of metastatic renal cell carcinoma from a native kidney of a 54 year-old male patient, who had a 5-years history of renal transplant, by EUS-FNA of mediastinal and celiac lymph nodes. Histological and immunohistochemical findings confirmed the origin of metastatic tumor. EUS-FNA with proper cytological evaluation can be useful in the diagnosis of metastatic renal cell carcinoma in renal transplant patients. PMID:28326261

    The objective of this present study is to analyze individual and contextual factors associated with access to renal transplant in Brazil. An observational, prospective and non-concurrent study was carried out, based on data from the National Database on renal replacement therapies in Brazil. Patients undergoing dialysis between 01/Jan/2000 and 31/Dec/2000 were included and monitored up to the point of transplant, death or until the end of the study period. Variables that were analyzed included: individual variables (age, sex, region of residence, primary renal disease, hospitalizations); and context variables concerning both the dialysis unit (level of complexity, juridical nature, hemodialysis machines and location) and the city (geographic region, location and HDI). Proportional hazard models were adjusted with hierarchical entry to identify factors associated with the risk of transplant. The results point to differentials in access according to socio-demographic, clinical, geographic and social factors, indicating that the organ allocation system has not eliminated avoidable disparities for those who compete for an organ in the nationwide waiting list.

    Objective: Our goal is to investigate the distribution of MEFV mutations in patients with renal amyloidosis who are in renal transplant waiting list which is prepared for transplantation. Materials and Methods: FMF was diagnosed in 25 of the 297 patients between the years 2004 and 2008, who were involved in the study (15 male, 10 female; age 34±7.8). 5 out of 25 patients were transplanted, remaining were waiting for Tx. Biopsy results were amyloidosis and taken from renal (n:16), rectal (n:8) and duodenal (1).All of them were carrier of mutations in both pyrin alleles.The primer cause of chronic renal failure in our group was secondary AA amyloidosis. DNA was isolated from 25 whole blood samples. The NanoChip Molecular Biology Workstation (Nanogen) uses electronic microarrays for mutation detection. Exon 2,3,5 and 10 of pyrin gene genotypes were identified in the NanoChip. Results: Genetic analysis of the patients demonstrated that each subject carries either homozygote or compound heterozygote mutations of the gene. The most common mutations were M694V, V726A, E148Q and M680I. Conclusions: The clinic manifestation and complain of our patients were febrile and painful attacks such as in the abdomen, chest and joints due to inflammation of the peritoneum, pleura and synovial membrane. The major problem in FMF is the occurrence of amyloidosis that primarily affects the kidneys causing proteinuria and renal failure. Dialysis and renal transplantation can be treatment, but it is important to diagnose FMF at earliest stages. The percentage of FMF patients in our waiting list was 8.4%. Moreover, in our region FMF incidence is highly frequent, so FMF should be chased by genetically so as to prevent chronic renal failure due to amyloidosis. PMID:25610112

    In 2006, a survey from the American Society of Transplant Surgeons disclosed significant and sometimes fatal hemorrhagic events in live donor nephrectomies (LDN) related to failure of clips, leading to the contraindication of the Weck® Hem-o-lok® clip for control of the renal artery during LDN. A survey regarding vascular control techniques, their perceived safety ratings and their failures was sent to 645 European Society for Organ Transplantation members who profiled their profession as "surgeon" and selected "kidney" as organ type. Two hundred forty-three (41%) members responded, of whom 171 (63.3%) independently perform LDN. Their responses were analyzed. For arterial and venous vascular control, the GIA™ and TA™stapler are used most frequently, and were rated the safest. Of the 121 reported hemorrhagic events, slippage and dislodgement of clips occurred at least 58 times, while stapler malfunction occurred at least 40 times. One donor death from hemorrhage related to clip dysfunction was reported. Hemorrhagic complications of LDN with fatal and non-fatal outcomes still occur. Strikingly, many surgeons do not use the vascular closing technique that they consider most safe. Failure of non-transfixion techniques is associated with greater risks for the donor. Control of major vessels in LDN must employ transfixion techniques for optimal donor safety.

    Faced with the long waiting list for a kidney transplant, the use of donors with expanded criteria, like polycystic kidneys, is an option that aims to increase in a short time the supply of kidneys for transplant. This report of two cases of transplants performed from a donor with polycystic kidneys showed promising results, and the receptors evolved with good renal function, serum creatinine measurements within the normal range and with adequate glomerular filtration rate, evaluated over a period of four years post transplant. This fact confirms that the option of using donors with polycystic kidneys is safe and gives good results.

    Kidney transplantation greatly benefits end-stage renal disease patients, as they no longer must bear the torment of hemodialysis. However, the effectiveness of living-donor kidney transplantation is often negatively impacted by various complications, which patients may learn to control through related self-care strategies. However, lack of information on these complications and related strategies may lead to feelings of uncertainty and worries over the prognosis. This article discusses a nursing experience with a patient who underwent living-donor kidney transplantation and who suffered from immense uncertainty and prognosis-related worry. Based on the assessment framework of Mishel's uncertainty theory, the authors identified the cause of the subject's uncertainty and offered thorough information regarding post-transplant care. During the period of care, the subject gained self-care knowledge and skills. Furthermore, he learned to apply self-recording, a technique that enabled him to self-monitor the progress of his disease progress, which reduced his sense of insecurity significantly. Ultimately, the subject turned uncertainty into motivation in order to actively participate in his treatment and to maintain optimum health status.

    Background: Renal transplantation is the best treatment for end stage renal disease. Acute graft rejection is one of the main complications and may influence graft survival. Objective: To determine the incidence and features of acute cellular rejection (ACR) episodes confirmed by biopsy. Methods: We studied a cohort of 175 patients who underwent renal transplantation between 2004 and 2012 to determine the cumulative incidence of ACR confirmed by biopsy and to identify the associated risk factors using multivariate analysis. Results: The one-year patient survival was 96.6%; the graft survival was 93.7%. The incidence of ACR within one year was 14.3%, of which 46% were observed within 6 months following transplantation. The most frequently observed ACR type was 1B according to the Banff classification system (42%). A relationship between ACR and receipt of a kidney from expanded criteria donors was observed, both in univariate and adjusted multiple log-binomial regression analyses, but only 6.3% of patients received extended criteria donor kidneys. No other relationships between variables were found. Conclusion: ACR frequency in this study was similar to that of other cohorts reported previously. We need a bigger sample of renal transplants from expanded criteria donors, PRA and DSA test to support the results. PMID:27721962

    West Nile virus (WNV), a mosquito-transmitted single-stranded RNA flavivirus, causes human disease of variable severity. We report clinical and pathologic findings of fatal encephalitis from the transmission of WNV from an organ donor to a kidney transplant recipient. The patient developed a febrile illness 18 days after transplantation, which progressed to encephalitis. Postmortem examination demonstrated extensive viral encephalopathic changes. Immunohistochemical studies highlighted WNV antigens within neurons, especially in the cerebellum and brainstem. Flavivirus virions were detected ultrastructurally within the cerebellum, and WNV was isolated from the brain and the brainstem. Thus, this case demonstrates the first death in the first solid organ transplant-associated transmission of WNV. Immunosuppression of the transplant recipient might have been responsible for the fulminant viral effects. The pathologic diagnosis helped guide subsequent epidemiologic and laboratory studies.

    Introduction: Renal transplantation are admitted to emergency department (ED) more than normal population. The present brief report aimed to determine the reasons of renal transplant patients’ ED visits. Methods: This retrospective case series study analyzed the reasons of renal transplant recipients’ admission to one ED between 2011 and 2014. The patient data were collected via a checklist and presented using descriptive statistics tools. Results: 41 patients with the mean age of 40.63 ± 10.95 years were studied (60.9% male). The most common ED presenting complaints were fever (36.6%) and abdominal pain (26.8%). Infections were the most common final diagnosis (68.3%). Among non-infectious causes, the most common was acute renal failure (9.7 %). 73.2% of the patients were hospitalized and no cases of graft loss and mortality were seen. Conclusion: The most common reason for ED admission was fever, and infections were the most common diagnosis. Acute gastroenteritis being the most frequent infection and among non-infectious problems, acute renal failure was the most frequent one. PMID:27800542

    Tuberous sclerosis complex (TSC) is caused by constitutively activated mammalian target of rapamycin (mTOR) resulting in nonmalignant tumours of several organs and consequently renal failure. Recent reports suggest a possible beneficial role of the mTOR-inhibitor (mTOR-I) sirolimus for TSC; however, safety and efficiency of sirolimus in TSC patients after renal transplantation, both as primary immunosuppressant as well as anti-proliferative agent, are still undefined. Moreover, it is currently unknown whether the TSC mutation affects the primary immune response in these patients. In this article, we report on three TSC patients after renal transplantation who have been converted from a calcineurin-inhibitor (CNI)-based immunosuppression to sirolimus. During 2 years of follow-up, renal allograft function was stable or even improved, and no significant sirolimus-associated side-effects were noted. Beneficial effects of sirolimus against TSC were detected in the skin, along with improved spirometric measurements and an arrest of astrocytoma progression. We show that the inflammatory immune response was significantly altered in TSC patients as compared with controls and sirolimus potently affected both inflammatory cytokine production and vascular endothelial growth factor levels in these patients. Larger studies are warranted to further examine the relationship between clinical parameters and the molecular response to mTOR-inhibition in TSC patients after renal transplantation.

    The significance of BK viruria and viremia in non-renal solid organ transplants is poorly understood. A systematic review was performed reviewing the incidence and implications of BK virus replication in non-renal solid organ transplants. Ninety-seven studies were identified, of which 18 including lung, heart, liver and pancreas transplants were included. The overall incidence of BK viruria and viremia was 20% and 3% respectively and 17 cases of BK nephropathy were identified. Heart transplant recipients had a higher overall incidence of BK viremia than other non-renal organ types, and the majority of cases of BK virus-associated nephropathy were in heart transplant recipients. The incidence of BK viremia was significantly lower in non-renal solid organ transplants than that of renal transplant recipients and BK virus-associated nephropathy was rare. BK virus-associated nephropathy may be considered in heart transplant recipients who have unexplained and persistent renal dysfunction not attributable to other causes.

    Long term immunosuppression following organ transplantation promotes the onset of skin cancers. A renal transplant patient developed multiple hyperkeratotic nodi in the left hand and digital pain following prolonged immunosuppression. Several skin abnormalities were observed in an ischemic and atrophic left hand in the presence of a patent Cimino-Brescia arteriovenous fistula previously used for hemodialysis. Severe hand ischemia was confirmed by digital plethysmography. Pathological examination of all 7 excised skin lesions indicated manifestations of well differentiated squamous cell carcinomas (SCC). Severe loco-regional ischemia due to an intact hemodialysis access may enhance the toxic effects of chronic immunosuppressive medication. Oxidative stress may act as a co-carcinogenic factor for the development of SCC in renal transplant patients receiving immunosuppressive agents.

    Introduction ABO-incompatible (ABOi) renal transplantation (RTx) from living donors is an established procedure to expand the donor pool for patients with end stage renal disease. Immunoadsorption (IA) is a standard procedure for the removal of preformed antibodies against the allograft. In this study, antigen-specific and non-antigen-specific IA in ABOi RTx were compared. Patients and Methods 10 patients underwent antigen-specific IA (Glycosorb group) and 13 patients non-antigen-specific IA (Immunosorba group). The effects of both procedures regarding antibody reduction, number of treatments, complications, costs, as well as the allograft function and patient survival were compared between both groups. Results Although the IgG levels were reduced equally by both procedures (p=0.82), the reduction of the IgM level was more effective in the Glycosorb group (p=0.0172). Patients in both groups required a median number of 6 IA before ABOi RTx. Allograft function at one year after AB0i RTx was similar in both groups (estimated glomerular filtration rate: 66 vs. 64 ml/min/1.73m² respectively), with a death-censored graft survival of 90.0% and 92.3% respectively. Complication rates did not differ between procedures. Due to the reuse of non-antigen-specific Immunosorba columns, costs were considerably lower in this group; however, the use of the Immunosorba-based IA was less time-efficient. Conclusion Considering upcoming alternatives as simultaneous performance of dialysis and IA or a possible reuse of Glycosorb columns, this might become less relevant in the future. PMID:26121389

    Hypogonadism is a common problem in the end-stage renal disease (ESRD) and renal transplant population. It has widespread systemic effects and has been linked with mortality in dialysis patients and at the time of renal transplant. The etiology is likely multifactorial and most patients are afflicted by various comorbidities that can contribute to hypogonadism. Clinical manifestations are mostly nonspecific. We review the approach to the diagnosis of hypogonadism, focusing on both laboratory values and clinical signs and symptoms. We review treatment with testosterone replacement in this population and highlight various studies that tend to have small sample sizes. Though these studies provide insight into testosterone replacement, the need for larger studies is emphasized to better understand the effects and safety of therapy. PMID:28078220

    SDZ RAD and mycophenolate mofetil (MMF) are increasingly used in the prevention of renal allograft rejection. SDZ RAD, having a macrolide structure, and MMF, known with gastrointestinal side-effects, may have gastric motility modifying properties. Gastric emptying was examined 1 yr after renal transplantation in eight patients taking corticosteroids (CS), cyclosporin A (CsA) and SDZ RAD and six patients treated with CS, CsA and MMF. Comparing the two groups, no significant differences in gastric emptying of solids and liquids were noted. Compared with normal volunteers, solid gastric emptying was faster in the SDZ RAD group and similar in the MMF group. It is concluded that in stable renal transplant recipients treated with MMF, gastric emptying was normal. Because of the impact on drug absorption and gastrointestinal symptoms, further studies are indicated to corroborate the potential prokinetic properties of SDZ RAD.

    Introduction: Previous publications have shown an increased incidence of various malignancies amongst renal transplant populations. The objective of this study was to analyze the rate and types of malignancies occurring in the St. Michael's Hospital renal transplant population and to determine whether our results were comparable to those previously published. Methods: After approval by the hospital's research ethic board, review of the records and pathology of the 1584 patients in the renal transplant clinic database patients was performed. The reports dated back to the year 1970. Results: Amongst the 1584 renal transplant patients, 106 patients with 132 dysplastic and malignant posttransplant lesions were identified. The highest incidence amid the malignancies was in nonmelanoma skin malignancies squamous cell carcinoma (SCC), basal cell carcinoma, and Kaposi sarcoma, with a total of 32 patients having 54 separate tumors (2.02% of all patients, 43.2% of tumors). Following skin tumors in incidence were genitourinary (28 tumors), gastrointestinal tract (GIT) lesions (8 adenocarcinomas, 14 dysplastic lesions, 1 low grade neuroendocrine tumor/carcinoid), posttransplant lymphoproliferative disorders (PTLDs) (10 cases), gynecologic (6 carcinomas), cervical/anal/vulvar dysplasia and invasive (SCCs) (4), and thyroid (3 papillary tumors). Nine patients had tumors of multiple sites/types. With respect to outcome, 14 patients died of malignancy, with the highest mortality being in the GIT malignancies (six patients). Second in mortality were the PTLD and skin tumor groups. Discussion: Information on the incidence and outcome of various malignancies in renal transplant patients is important in designing guidelines for the follow-up of these patients regarding tumor screening and prevention. The rate of malignancies in our group is comparable to that reported in other centers. PMID:27141185

    In this report we present the current status of the renal replacement therapy in Sudan. Sudan is a large country with 30 million inhabitants. Peritoneal Dialysis was started in 1968, while hemodialysis was started in 1973. At present, there are only 16 hemodialysis machines serving 56 patients in two centers in Sudan. There are also 15 peritoneal dialysis beds for 70 intermittent peritoneal dialysis patients in three centers. Continuous ambulatory peritoneal dialysis is not being practiced in Sudan. The first renal transplant was in 1974, and till now more than 30 transplants have been performed in two transplant centers. All the transplants have been from living donors. The scholars of Islam in Sudan oppose to donation from cadavers. There are 200 renal transplant patients being followed up in Sudan and the majority had their renal transplants abroad. We conclude that there is a tremendous shortage of renal services in Sudan. There are more efforts being made to improve these services.

    MPA is an immunosuppressive agent used to prevent graft rejection after renal transplantation. MPA shows considerable inter- and intraindividual variability in exposure in children and has a defined therapeutic window, and TDM is applied to individualize therapy. We aimed to study the exposure to MPA measured as the AUC in pediatric renal transplant patients, to identify factors influencing exposure and to assess target attainment. Children transplanted between 1998 and 2014 in a single center were included. Two groups were identified: Group 1 (AUC <3 wk post-transplantation) and Group 2 (AUC >18 months post-transplantation). Therapeutic targets were set at: AUC0-12h of 30-60 mg h/L. A total of 39 children were included in Group 1 (median age 13.3 yr) vs. 14 in Group 2 (median age 13.4 yr). AUC0-12h was 29.7 mg h/L in Group 1 and 56.6 mg h/L in Group 2, despite a lower dosage in Group 2 (584 and 426 mg/m(2) , respectively). About 46% of patients reached the target AUC0-12h in Group 1. Time since transplantation and serum creatinine were significantly associated with MPA exposure (p < 0.001), explaining 36% of the variability. Individualization of the mycophenolate dose by more intense and more early TDM could improve target attainment.

    Sensitization following renal transplant is a significant barrier to repeat transplantation in children. We report a successful DD renal transplant, with the use of PP, in an 11-yr-old girl who became highly sensitized following a prior failed transplant. She received PP treatments after failure of high-dose IVIg (Gamimune). We established the effectiveness of PP by attaining a 0% PRA and negative cross-matches after five PP treatments. Subsequently, our patient underwent a second round of scheduled PP. When the PRA was 0%, unacceptable antigens were removed from the UNOS wait list, PP was continued, and a kidney became available within 10 days. The final flow cytometry cross-match with the eventual donor was negative. This success demonstrates that coordination of desensitization by PP and advanced laboratory monitoring techniques with recent policies regarding allocation of organs to pediatric patients provides new opportunities for children awaiting transplantation. Since the transplant, our patient sustained a low-titer increase of anti-HLA antibodies. However, she has had no episodes of acute rejection and has maintained excellent graft function more than 17 months later.

    Thrombotic microangiopathy (TMA) is a rare but serious complication of organ transplantation. This article presents the first literature review on TMA following non-renal solid organ transplantation (SOT). Ischemia-reperfusion, immunosuppressive drugs, acute interfering disease and a relative deficiency of the von Willebrand factor (vWF) cleaving protease (ADAMTS13) appear to play a major role in its pathogenesis. De novo TMA occurs in 4.0% of liver and 2.3% of lung transplant recipients, whereas the incidence remains unknown after intestinal transplantation. The median time of onset is 2, 37 and 8 weeks after liver, lung and intestinal transplantations respectively, with a three month survival of about 70%. In heart transplantation TMA is rare, occurrence is late and prognosis is poor. In TMA early after liver transplantation an elevated vWF/ADAMTS13 ratio may show diagnostic value. Early withdrawal of calcineurin inhibitors (CNI) proves to be lifesaving. Conversion to another CNI and rechallenge after resolution are generally safe, except after heart transplantation. The value of plasma exchange therapy remains controversial.

    The cornerstone events of transplantation history in Turkey are summarized herein. In 1975, we performed the first living-related renal transplant in Turkey. We followed this in 1978 with the first deceased donor kidney transplantation, using an organ supplied by Eurotransplant. In 1979, the law on harvesting, storage, grafting, and transplantation of organs and tissues was enacted; later that year, the first local deceased donor kidney transplantation was performed by our team. In 1988, another groundbreaking event in Turkey was successfully achieved: the first cadaveric liver transplantation. In 1990, the first pediatric living-related segmental liver transplantation in Turkey, the region, and Europe was performed by our team. One month later, an adult-to-adult living-related liver transplantation was successfully performed. In May 1992, we performed the first combined liver-kidney transplantation from a living-related donor, which was the first operation of its kind. To date, we have performed 2,084 kidney and, since 1988, 439 liver transplantations. During 29 years of solid organ transplantation history in Turkey, 20,794 kidney transplants have been performed nationwide in 62 different centers, as well as 6,565 liver, 621 heart, and 168 pancreas transplants. In 2001, the Ministry of Health established the National Coordination Center as an umbrella organization to promote transplantation activities, especially for deceased donor organ procurement. Transplantation activities are accelerating daily throughout the country, but deceased donors are still far below the desired rates.

    Survival benefit of simultaneous liver-kidney transplant (SLKT) over liver transplant alone (LTA) is unclear from the current literature. Additionally, the role of donor kidney quality, measured by kidney donor risk index (KDRI), in survival benefit of SLKT is not studied. We compared survival benefit after SLKT and LTA among recipients with similar pre-transplant renal dysfunction using novel methodology, specifically with respect to survival probability and area under the survival curve by dialysis status and KDRI. Methods Data were obtained from the Scientific Registry of Transplant Recipients. The study cohort included patients with pre-LT renal dysfunction who were waitlisted and received either a SLKT (n=1,326) or a LTA (n=4,283) between 3/1/02–12/31/09. Inverse Probability of Treatment Weighted (IPTW) – SLKT and LTA survival curves, along with the 5-year area under the survival curve were computed by dialysis status at transplant. The difference in the area under the curve represents the average additional survival time gained via SLKT over LTA. Results For patients not on dialysis, SLKT resulted in a significant 3.7 month gain in 5-year mean post-transplant survival time. The decrease in mortality rate differs significantly by KDRI, and an estimated 76% of SLKT recipients received a kidney with KDRI sufficiently low for mortality. The mortality decrease for SLKT was concentrated in the first year post-transplant. The difference between SLK and LTA 5-year mean post-transplant survival time was 1.4 months and non-significant for patients not on dialysis. Conclusion The propensity score-adjusted survival among SLKT and LTA recipients was similar for those who were dialysis at LT. Although statistically significant, the survival advantage of SLKT over LTA was of marginal clinical significance among patients not on dialysis; and occurred only if the donor kidney was of sufficient quality. These results should be considered in the ongoing debate regarding the

    One of the main issues in kidney transplantation is the optimal functional preservation of the organ until its transplantation into the appropriate recipient. Despite intensive efforts, the functional preservation period remains limited to hours. During this time, as a result of cellular injury, various proteins, peptides, and other molecules are released by the organ into the preservation medium. In this study, we used proteomic techniques to analyze the protein profiles of preservation solutions in which organs had been preserved prior to their transplantation. Samples were obtained from the preservation solutions of 25 deceased donor kidneys scheduled for transplantation. The protein profiles of the solutions were analyzed using 2D gel electrophoresis/MALDI-TOF and LC-MS/MS. We identified and quantified 206 proteins and peptides belonging to 139 different groups. Of these, 111 proteins groups were belonging to kidney tissues. This study used proteomic techniques to analyze the protein profiles of organ preservation solutions. These findings will contribute to the development of improved preservation solutions to effectively protect organs for transplantation. PMID:28036361

    2012-01-01

    For kidney transplant recipients, immunosuppression commonly consists of combination treatment with a calcineurin inhibitor, an antiproliferative agent and a corticosteroid. Many medical centers use a sequential immunosuppression regimen where an induction agent, either an anti-thymocyte globulin or interleukin-2 receptor antibody, is given at the time of transplantation to prevent early acute rejection which is then followed by a triple immunosuppressive maintenance regimen. Very low rejection rates have been achieved at many transplant centers using combinations of these agents in a variety of protocols. Yet, a large number of recipients suffer chronic allograft injury and adverse events associated with drug therapy. Regimens designed to limit or eliminate calcineurin inhibitors and/or corticosteroid use are actively being pursued. An ideal immunosuppressive regimen limits toxicity and prolongs the functional life of the graft. This article contains a critical analysis of clinical data on currently available immunosuppressive strategies and an overview of therapeutic moieties in development. PMID:24175197

    Excessive weight gain is common after renal transplantation, but it is unknown whether environmental factors, such as food availability, contribute to this important clinical problem. We evaluated the effects of food availability (fast food restaurants, convenience stores, and grocery stores within 1, 2, and 3 mile buffers of transplant recipients' residences) on body mass index (BMI) change during the first year post-transplant. Participants (n = 299) resided in Memphis, Tennessee. BMI increased by 1.42 units (p < .001) corresponding to an average weight gain of 9.25 lbs (5.43%) during the first year post-transplant. The number of grocery stores within 1 mile of recipient's residence was associated with an increase in BMI (p < .05), but fast food restaurants and convenience stores were not significantly associated with BMI change.

    In patients undergoing renal transplantation, dose individualization for tacrolimus is routinely achieved with therapeutic drug monitoring (TDM). The patient started on 5.5 mg/day of tacrolimus had a significantly elevated tacrolimus trough concentration. The tacrolimus dose was regularly reduced following TDM at many time periods in the post transplant period but the tacrolimus concentration was consistently elevated. Genomic analysis done after four years revealed mutations in the genes encoding for CYP3A5 and MDR1 (2677G > T). Pharmacogenomics alongside TDM, will soon emerge as the backbone of dose individualization. But for genomics to be beneficial, it should be advocated in the pre-transplant or early post transplant period.

    A decrease in live donor pediatric kidney transplants has occurred in the United States. This study investigates barriers that may influence access to live donor kidney transplants in children. Retrospective chart review was conducted for 91 children (69% male, mean age 11.9 years) who underwent pretransplant workup from 2005 to 2015 at an urban pediatric hospital. Fifty-four percent were African American, 32% Caucasian, 8% Arabic, 3% Hispanic, and 3% Others. Government-sponsored insurance (Medicaid/Medicare) was utilized by 73%, and 54% had dual caregivers. Only nine of 68 kidney transplants were live donor transplants. Live donor transplants (11%) were significantly (P=.008) lower than deceased donor transplants (59%) in African Americans. Private insurance was reported by 56% of live donor recipients and 25% of deceased donor recipients. Among live donor recipients, 78% were from dual caregiver families. Caregiver, health-related, financial, and religious/cultural barriers to live donor transplants were reported, several of which may be amenable to positive intervention.

    The objective of this study was to evaluate the results of adult ABO-incompatible living donor liver transplantation (LDLT).ABO-incompatible LDLT is an aggressive treatment that crosses the blood-typing barrier for saving lives from liver diseases. Although graft and patient survival have been improved recently by various treatments, the results of adult ABO-incompatible LDLT require further evaluation.Two regimens were designed based on isoagglutinin IgG and IgM titers and the time course of immunological reactions at this institute. When isoagglutinin IgG and IgM titers were ≤64, liver transplantation was directly performed and rituximab (375 mg/m) was administrated on postoperative day 1 (regimen I). When isoagglutinin titers were >64, rituximab (375 mg/m) was administered preoperatively with or without plasmapheresis and boosted on postoperative day 1 (regimen II). Immunosuppression was achieved by administration of mycophenolate mofetil, tacrolimus, and steroids.Forty-six adult ABO-incompatible and 340 ABO-compatible LDLTs were performed from 2006 to 2013. The Model for End-Stage Liver Disease scores for ABO-incompatible recipients ranged from 7 to 40, with a median of 14. The graft-to-recipient weight ratio ranged from 0.61% to 1.61% with a median of 0.91%. The 1-, 3-, and 5-year survival rates were 81.7%, 75.7%, and 71.0%, respectively, for ABO-incompatible LDLT recipients, compared to 81.0%, 75.2%, and 71.5% for ABO-C recipients (P = 0.912). The biliary complication rate was higher in ABO-incompatible LDLT recipients than in the ABO-compatible recipients (50.0% vs 29.7%, P = 0.009).In the rituximab era, the blood type barrier can be crossed to achieve adult ABO-incompatible LDLT with survival rates comparable to those of ABO-compatible LDLT, but with more biliary complications.

    Background. End-stage renal disease (ESRD) is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Objectives. To analyze the outcome and prognostic factors of renal transplantation in patients with ESRD due to SLE from January 1986 to December 2013 in a single center. Results. Fifty renal transplantations were performed in 40 SLE patients (32 female (80%), mean age at transplantation 36 ± 10.4 years). The most frequent lupus nephropathy was type IV (72.2%). Graft failure occurred in a total of 15 (30%) transplantations and the causes of graft failure were chronic allograft nephropathy (n = 12), acute rejection (n = 2), and chronic humoral rejection (1). The death-censored graft survival rates were 93.9% at 1 year, 81.5% at 5 years, and 67.6% at the end of study. The presence of deceased donor allograft (P = 0.007) and positive anti-HCV antibodies (P = 0.001) negatively influence the survival of the renal transplant. The patient survival rate was 91.4% at the end of the study. Recurrence of lupus nephritis in renal allograft was observed in one patient. Conclusion. Renal transplantation is a good alternative for renal replacement therapy in patients with SLE. In our cohort, the presence of anti-HCV antibodies and the type of donor source were related to the development of graft failure. PMID:25013800

    This report describes a 1-yr-old boy with biliary atresia (BA) and polysplenia syndrome (PS) who underwent successful living-related liver transplantation (LTx). At the time of initial hepatic portoenterostomy, he was noticed to have a preduodenal portal vein (PV), non-rotation of the intestine, and polysplenia. Because he did not achieve good bile excretion, he underwent a living-related LTx (using a left lateral segment from his mother) at the age of 14 months. Evaluation of the vascular anatomy was made by angiography, magnetic resonance imaging (MRI), computerized tomography (CT), and Doppler ultrasound. The PV was stenotic from the confluence of the superior mesenteric vein (SMV) and splenic vein (SpV) to the hepatic hilum. The retrohepatic inferior vena cava (IVC) was deficient cranially to the renal vein and was connected to the azygous vein. The supra-hepatic IVC was detected below the diaphragm and was connected to three hepatic veins. The common hepatic artery (HA) originated from the superior mesenteric artery. At LTx, the PV was dissected to the level of confluence of the SMV and the SpV, from which the venous graft was interposed using the donor's ovarian vein. Three hepatic veins were plastied into one orifice, which was anastomosed to the graft's hepatic vein under the diaphragm. The graft vascularity and function has been good for 1 yr after LTx. In the present case, sufficient pre-LTx evaluation of vascular anomalies seemed to help performance of the successful LTx.

    Background: Kidney transplantation is a preferred treatment for many patients with end-stage renal disease (ESRD) and is far more profitable than hemodialysis. Analyzing renal transplantation data can help to evaluate the effectiveness of transplantation interventions. The aim of this study was to determine the organ survival rate after kidney transplantation during a period of 10 years (March 2001-March 2011) among transplanted patients in Arak, Markazi Province, Iran. Materials and Methods: In this historical cohort study, all recipients of kidney transplantation from Arak, Markazi Province, Iran who had medical records in Valiasr Hospital and “charity for kidney patients” of Arak, Markazi Province, Iran during a period of 10 years from March 2001 to March 2011 were included. Data collected by using checklists were completed from patients’ hospital records. Kaplan-Meier method was used to determine the graft cumulative survival rate, log-rank test to compare survival curves in subgroups, and Cox regression model to define the hazard ratio and for ruling out the intervening factors. Statistical analysis was conducted by Statistical Package for the Social Sciences (SPSS) 20 and Stata 11. Results: Mean duration of follow-up was 55.43 ± 42.02 months. By using the Kaplan-Meier method, the cumulative probability of graft survival at 1, 3, 5, 7, and 10 years was 99.1, 97.7, 94.3, 85.7, and 62.1%, respectively. The number of dialysis by controlling the effect of other variables had a significant association with the risk of graft failure [hazard ratios and 95% confidence interval (CI): 1.47 (1.02-2.13)]. Conclusion: This study showed that the graft survival rate was satisfactory in this community and was similar to the results of single-center studies in the world. Dialysis time after transplantation was a significant predictor of survival in the recipients of kidney transplantation that should be considered. PMID:26941807

    The purpose of this study was to evaluate the long-term outcome of percutaneous therapy of ureteral complications after renal transplantation. Between January 2000 and June 2006 we percutaneously treated 26 renal transplant patients with ureteral obstruction (n=19) and leak (n=7). Obstructions were classified as early (<2 months after transplantation) or late (>2 months). Patients with leak were treated with nephro-ureteral catheter placement and subsequent double-J stenting. Balloon dilatation, stent placement, and basket extraction were used to treat ureteral obstructions. Patients were followed with ultrasonography. No major procedure-related complication occurred. The mean follow-up time was 34.3 months (range: 6 to 74 months). Initial clinical success was achieved in all 19 patients with obstruction and 6 of 7 patients with leak. Four of 9 early obstructions and 4 of 10 late obstructions recurred during the follow-up. All recurrences were initially managed again with percutaneous methods, including cutting balloon technique and metallic stent placement. Although there was no recurrence in patients with successfully treated leak, stricture was seen at the previous leak site in two patients. These strictures were also successfully managed percutaneously. We conclude that in the treatment of ureteral obstruction and leak following renal transplantation, percutaneous therapy is an effective alternative to surgery. However, further interventions are usually needed to maintain long-term patency.

    With the current shortage of solid organs for transplant, the transplant community continues to look for ways to increase the number of organ donors, including extending the criteria for donation. In rhabdomyolysis, the byproducts of skeletal muscle breakdown leak into the circulation resulting in acute renal failure in up to 30% of patients. In nonbrain dead patients, this condition is reversible and most patients recover full renal function. Seven potential donors had rhabdomyolysis with acute renal failure as evidenced by the presence of urine hemoglobin, plasma creatinine kinase levels of greater than five times the normal and elevated creatinine. One donor required dialysis. At our institution, 10 kidneys were transplanted from the seven donors. Two grafts had immediate function, five grafts experienced slow graft function and three grafts had delayed graft function requiring hemodialysis. At a mean of 8.7 months posttransplant (2.4-25.2 months), all patients have good graft function, are off dialysis and have a mean creatinine of 1.3 (0.7-1.8). In conclusion, our experience suggests that rhabdomyolysis with acute renal failure should not be a contraindication for donation, although recipients may experience slow or delayed graft function.

    Despite excellent short-term graft survival after renal transplantation, the long-term graft outcome remains compromised. It has become evident that a combination of sustained alloreactivity and calcineurin-inhibitor- (CNI-) related nephrotoxicity results in fibrosis and consequently dysfunction of the graft. New immunosuppressive regimens that can minimize or eliminate side effects, while maintaining efficacy, are required to improve long-term graft survival. In this perspective mesenchymal stromal cells (MSCs) are an interesting candidate, since MSCs have immunosuppressive and regenerative properties. The first clinical trials with MSCs in renal transplantation showed safety and feasibility and displayed promising results. Recently, the first phase II studies have been started. One of the most difficult and challenging aspects in those early phase trials is to define accurate endpoints that can measure safety and efficacy of MSC treatment. Since both graft losses and acute rejection rates declined, alternative surrogate markers such as renal function, histological findings, and immunological markers are used to measure efficacy and to provide mechanistic insight. In this review, we will discuss the current status of MSCs in renal transplantation with a focus on the endpoints used in the different experimental and clinical studies. PMID:26258149

    There have been several retrospective studies indicating benefits associated with mycophenalate mofetil (MMF) compared to azathioprine (AZA) for renal transplant recipients. However, these analyses evaluated outcomes prior to changes in utilization patterns of concomitant immunosuppression. Recent prospective trials have indicated similar outcomes among patients treated with MMF and AZA. The aim of this study was to evaluate outcomes in a broad group of patients in the more recent era. We evaluated adult solitary renal transplant recipients from 1998 to 2006 with the national SRTR database. Primary outcomes were time to patient death and graft loss, complications and renal function. Models were adjusted for potential confounding factors, propensity scores and stratified between higher/lower risk transplants and concomitant immunosuppression. Adjusted models indicated a modest risk among AZA patients for graft loss (AHR = 1.14, 95% CI 1.07-1.20); however, this was not apparent among AZA patients also treated with tacrolimus (AHR = 0.97, 95% CI 0.85-1.11]. One-year acute rejection rates were reduced for patients on MMF versus AZA (10 vs. 13%, p < 0.01); there were no statistically significant differences of malignancies, renal function or BK virus at 1 year. The primary findings suggest the association of MMF with improved outcomes may not be apparent in patients also receiving tacrolimus.

  15. Karyopherins: potential biological elements involved in the delayed graft function in renal transplant recipients

    PubMed Central

    2014-01-01

    Background Immediately after renal transplantation, patients experience rapid and significant improvement of their clinical conditions and undergo considerable systemic and cellular modifications. However, some patients present a slow recovery of the renal function commonly defined as delayed graft function (DGF). Although clinically well characterized, the molecular mechanisms underlying this condition are not totally defined, thus, we are currently missing specific clinical markers to predict and to make early diagnosis of this event. Methods We investigated, using a pathway analysis approach, the transcriptomic profile of peripheral blood mononuclear cells (PBMC) from renal transplant recipients with DGF and with early graft function (EGF), before (T0) and 24 hours (T24) after transplantation. Results Bioinformatics/statistical analysis showed that 15 pathways (8 up-regulated and 7 down-regulated) and 11 pathways (5 up-regulated and 6 down-regulated) were able to identify DGF patients at T0 and T24, respectively. Interestingly, the most up-regulated pathway at both time points was NLS-bearing substrate import into nucleus, which includes genes encoding for several subtypes of karyopherins, a group of proteins involved in nucleocytoplasmic transport. Signal transducers and activators of transcription (STAT) utilize karyopherins-alpha (KPNA) for their passage from cytoplasm into the nucleus. In vitro functional analysis demonstrated that in PBMCs of DGF patients, there was a significant KPNA-mediated nuclear translocation of the phosphorylated form of STAT3 (pSTAT3) after short-time stimulation (2 and 5 minutes) with interleukin-6. Conclusions Our study suggests the involvement, immediately before transplantation, of karyopherin-mediated nuclear transport in the onset and development of DGF. Additionally, it reveals that karyopherins could be good candidates as potential DGF predictive clinical biomarkers and targets for pharmacological interventions in renal

    The purpose of the present study was to assess the effect of intelligence, schooling, psychomotor, emotional, and social status on renal graft survival in children. Sixty-two cadaver renal transplant recipients were evaluated retrospectively and the influence of sex, age, weight, and the use of cyclosporin A (CyA) on the success rate of the graft from 1 to 5 years later was analyzed. Psychological and social scores were devised and included as factors predictive of survival of the graft. Univariate analysis showed that the following variables predicted renal graft survival: the use of CyA (P = 0.0002), pre-transplant dialysis (P = 0.04), weight at the time of transplantation (P = 0.072), and psychological scores (P = 0.064). Association analysis demonstrated that pre-transplantation dialysis was only a chance association and therefore the parameter was discarded. Multivariate analysis showed that the predictive parameters were the use of CyA, sex, weight in kilograms, and the psychological score. An equation was then derived from variables that predict the probability that a specific patient's graft will survive more than t months. This equation is the estimated survival distribution function and is as follow: S (t) = Exp {-Exp[-(0.8882x1 - 1.827x2 + 0.037x3 - 0.1746x4) + ln t - 4.7862]} where S (t) = the survival at t months post transplantation, x1 = sex (male 1, female 2), x2 = CyA (yes 1, no 2), x3 = weight in kilograms, and x4 = psychological score. The major impact of psychological factors on renal graft survival was surprising.

    The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (K/DOQI) provides evidence based clinical practice guidelines developed for all phases of kidney disease and related complications, from diagnosis to monitoring and management. Bone disease sets in during the early stages of Chronic Kidney Disease (CKD). Bone disease is observed in almost patients with chronic renal failure and after renal transplantation. Hyperparathyroid (high turnover) bone disease in patients with chronic renal failure is found most frequently followed by mixed osteodystrophy, low-turn over bone disease, and osteomalasia. Ninety to one hundred percent of kidney transplant patients have histological evidence of osteodystrophy and osteopenia (reduction of bone mass) following renal transplantation. Furthermore, osteoporosis is also appeared in many renal transplant recipients. After renal transplantation, renal osteodystrophy generally improves but bone mineral density (BMD) often worsens. When renal bone disease is assessed using a combination of biochemical markers, histology and bone densitometry, early intervention and carefully effective therapies might be reduced the morbidity associated with these common problems.

    Renal dysfunction in cirrhotic patients is primary related to disturbances of circulatory function, triggered by portal hypertension with chronic intrarenal vasoconstriction and hypoperfusion. Pretransplant renal function is an important factor implicated in the development of acute renal failure (ARF) after liver transplantation (OLT), but other factors mostly related to liver function seem to influence the development of ARF. The Acute Dialysis Quality Initiative workgroup developed the RIFLE classification to define ARF. We sought to evaluate the incidence of ARF among patients undergoing OLT, to evaluate the association of ARF with pre-OLT renal and hepatic functions, and to evaluate the influence of ARF on chronic kidney disease (CKD) at 1 month post-OLT. Clinical, renal, hepatic function, and donor risk index data of 24 patients who underwent deceased donor OLT were collected before transplantation, in the perioperative period and in the first month post-OLT. ARF occurred in 37.5% of patients with 56% developing the R grade and 44% the I grade; no patient showed the F grade. An association was observed between ARF and a higher Model for End-Stage Liver Disease (MELD) score and between ARF and a reduced pre-OLT serum albumin. No association was noted between ARF and other pre-OLT parameters. In cirrhotic patients serum creatinine is a bias for renal function assessment and the Modification of Diet in Renal Disease formula overestimates GFR. Post-OLT CKD was present in 6.7% of patients without ARF and in 44.4% of patients with ARF. The R grade developed more frequently among patients with viral cirrhosis. The association of ARF with MELD and hypoalbuminemia may be the result of a close relationship between renal and hepatic functions among cirrhotic patients. Post-OLT CKD may be the result of unrecognized, preexisting CKD and/or the effects of not fully resolved acute damage to an injured kidney.

    Introduction The use of a horseshoe kidney in renal transplant remains controversial, when it is found in the evaluation of a living donor, anatomical, surgical and ethical issues are involved. Presentation of Case An uncomplicated horseshoe kidney was detected in a 51-year-old woman who was the only suitable donor for her 30-year-old son. Kidneys were fused in the inferior pole and no vascular or urinary abnormalities were detected during imaging evaluation. The surgical procedure was approved by the hospital transplant committee. A laparotomy was performed by means of a medial upper incision. The isthmus of the kidney was divided using a harmonic scalpel and the left segment was used; it had 2 arteries too distant to create a common one, thus anastomosed separately. The renal vein was side-to-side anastomosed to the right external iliac vein and a Lich-Gregoir ureteral implant was made. There were no intraoperative or postoperative complications in the donor who currently remains asymptomatic. Recipient developed a delayed graft function (DGF), and was discharged on the 12th day after surgery. After 24 months of surgery, renal function has remained stable with a serum creatinine of 128 μmol/L (1.45 mg/dL). Discussion There are 7 reports of a horseshoe kidney from living donors in 8 patients without morbidity and a good long term outcome of all recipients. Conclusion If we anticipate a low operative risk and there is a suitable anatomy, we may consider the use of horseshoe kidneys from living donors a viable alternative. PMID:26299249

    Polyomavirus BK (BKPyV) is ubiquitous among humans. Following primary infection, the virus remains latent predominantly in the hosts' uroepithelial cells. Up to 10 % of renal transplant recipients show a viral reactivation that can lead to polyomavirus-associated nephropathy (PyVAN). In the absence of early treatments, the risk of graft loss is up to 80 %. Monitoring viral load in urine and plasma by real-time PCR after transplantation is the most common diagnostic tool to detect viral reactivation. In the present retrospective study, BKPyV-DNA loads in urine and plasma by quantitative real-time PCR were associated with clinical data, including HLA haplotype, blood parameters and viral genotype, of 40 renal transplant recipients at the University Clinics of Cologne. Seventeen out of 329 patients screened for BKPyV from January 2009 to October 2013 were detected BKPyV positive in urine only, whereas in 23 patients the virus became additionally detectable in plasma. Among these, ten patients progressed to PyVAN. Overall, the present study showed that the detection from the third month onwards after transplantation of a first viruric episode with a median viral load of 1 × 10(8) copies/mL, followed after few days by a first viremic episode with a median viral load of >1 × 10(4) copies/mL, was strongly associated with the development of PyVAN. In conclusion, the viral load and the temporal profile of the first viruric and viremic episode post-transplantation, in combination with specific features of the host immune response, should be considered as relevant clinical determinants of the risk of renal transplant recipients to progress to PyVAN.

    Outcomes of renal transplantation from donation after cardiac death (DCD) donors over 30 years were analyzed. Between 1975 and 2004, 256 renal transplantations from DCD donors were performed. The recipients were divided into four groups according to a time period as follows: 1975-1979 (Group 1; n = 18), 1980-1989 (Group 2; n = 81), 1990-1999 (Group 3; n = 84) and 2000-2004 (Group 4; n = 73). Of the 256 transplanted kidneys from DCD donors, 38 (15%) functioned immediately after transplantation. The incidence of delayed graft function (DGF) was 72%. Warm ischemic time and total ischemic time were 7.4 +/- 9.4 min and 11.9 +/- 5.6 h, respectively. The overall graft survival rates at 1, 5 and 10 years were 80%, 72% and 53%, respectively. Graft survival rates in each group have continually improved over time (5-year graft survival; 23% vs. 64% vs. 74% vs. 91%, respectively). However, there was no significant difference in graft survival rates between the groups of patients who survived with a functioning graft for more than 1 year. A multivariate Cox regression analysis showed acute rejection and donor age to be independently associated with graft outcome. DCD donors are a valuable source of kidneys for transplantation with promising long-term outcomes.

    Informed consent of the patient to medical treatment is an essential prerequisite for any invasive medical procedure. However in emergency cases, when the patient is unable to sign a consent form due to unconsciousness or to psychotic state, than the primary medical consideration shall take place. In such a case, in order to save life or even prevent a major medical hazard to the patient, doctors are allowed, in certain cases and in accordance with well accepted medical practice, to perform invasive procedures, major surgery or risky pharmacological treatment, without the explicit consent of the patient. All the above refers to the cases when avoidance of such non-consented treatment may harm severely the health and wellbeing of the patient and there is no doubt that such treatment is for the ultimate benefit of the patient. The question, however, shall arise when such a medical procedure is not necessarily for the benefit of the patient, but rather for the benefit of somebody else. Such is the case in the transplantation area and the question of living donor-donee relationship. This paper shall analyze the legal situation in cases of non competent donors whose consent cannot be considered legal consent given in full understanding and out of free will. It will also compare three legal systems, the Israeli, the American and the traditional Jewish law, with regard to the different approaches to this human problem, where the autonomy of the donor may be sacrificed for the purpose of saving life of another person.

    Pituitary apoplexy occurring after surgery is a rare but life-threatening acute clinical condition that follows extensive hemorrhagenous necrosis within a pituitary adenoma. Pituitary apoplexy has been reported to occur spontaneously in the majority of cases or in association with various inducing factors. Reported is a case of pituitary apoplexy complicated by diabetes insipidus following living donor liver transplantation (LDLT). To the best of our knowledge, this has not been previously reported. A 56-year-old woman with nonalcoholic steatohepatitis underwent LDLT from her daughter. The patient also required dopamine support and transfusions because of massive intraoperative bleeding. Postoperatively, her coagulopathy continued, and she underwent a second laparotomy because of unknown bleeding on postoperative day 7, when she needed transfusions and dopamine support to maintain her vital signs. She complained of severe headache, excessive thirst, frequent urination, and diplopia from postoperative day 10. She also had polyuria greater than 300 ml/h and was diagnosed with pituitary apoplexy precipitating diabetes insipidus on postoperative day 13. She was treated conservatively without surgery because of the hormonally inactive status and slight mass effect of her tumor. It is important for anesthesiologists and critical care personnel in LDLT settings to take into consideration this complication as a differential diagnosis.

    Objective: To explore the feasibility of the Chinese version of Kidney Transplant Questionnaire (KTQ) by evaluating the health-related quality of life (HRQoL) in Chinese recipients of living donor kidney transplantation. Methods: The English version of KTQ was translated into Chinese and underwent cultural adaptation to obtain the Chinese version of KTQ. HRQoL of 136 Chinese recipients of living donor kidney transplantation that met the inclusion criteria were evaluated to assess the validity and reliability of the questionnaire. Results: One hundred and thirty-six recipients (98 males and 38 females) of living donor kidney transplantation were included. The mean age of the recipients was 43.91 years. For each dimension of the questionnaire, the Cronbach’s alpha coefficient was 0.7-0.9, test-retest reliability coefficient ≥0.7, goodness of fit index (GFI) >0.9, and comparative fitness index (CFI) >0.9. Conclusion: The validity and reliability of the Chinese version of KTQ is similar to the English version, suggesting that the Chinese version of KTQ could be applied as a disease-specific questionnaire to evaluate the HRQoL of the recipients of living donor kidney transplantation in China.

    Alternariosis, caused by Alternaria spp., is a rare opportunistic infection often observed in immunocompromised patients. Alternaria is a ubiquitous saprophytic fungus that naturally is found on decaying plant materials. In this paper, a case of cutaneous alternariosis in association with tinea corporis is reported. The complicated infection was confirmed by histological examination and positive tissue culture. Although the cases of alternariosis in solid organ transplant recipients or Cushing's syndrome have been described elsewhere, this is the first report in a patient who had received two renal transplants who was co-infected with Alternaria spp. and Trichophyton rubrum.

As a consequence, the need for kidney transplantation in the geriatric population has increased, but the shortage of donors is an obstacle for geriatric renal transplantation. The aim of this study was to evaluate risk factors for graft failure and death in geriatric renal transplantation. Methods Kidney transplantations performed in a tertiary hospital in South Korea from May 1995 to December 2014 were retrospectively reviewed. Recipients younger than 60 years of age or who underwent other organ transplantations were excluded. The Kaplan-Meier method was used to assess patient and graft survival. A Cox regression analysis was used to evaluate risk factors for graft failure and patient death. Results A total of 229 kidney transplantation patients were included. Graft survival at 1, 5, and 10 years were 93.2%, 82.9%, and 61.2% respectively. Patient survival at 1, 5, and 10 years were 94.6%, 86.9%, and 68.8%, respectively. According to the Cox multivariate analysis, ABO incompatibility (hazard ratio [HR] 3.91,
