BACKGROUND: All living kidney donors are counseled about the possible surgical and medical risks associated with donation. Only a minority of transplant centers discuss the potential benefit of discovering undiagnosed medical conditions in the donor during evaluation, as part of their consent process. METHODS: We retrospectively investigated all potential living kidney donors evaluated over a 10-year period at a single center to characterize incidentally diagnosed serious medical conditions...

BACKGROUND: Thin basement membrane nephropathy (TBMN) is the most common cause of persistent glomerular hematuria. Most individuals with TBMN show a benign course, although it can be difficult to distinguish it from early stages of progressive renal diseases. However, only limited studies address the prognosis of donors with TBMN and their recipients. METHODS: From 2007 to 2016, 11 recipients received kidney grafts from donors with TBMN, and their clinical data were analyzed retrospectively...

BACKGROUND: Since soluble isoforms of MICA play an important role in modulating the immune response, we evaluated a possible correlation between their levels and development of acute rejection following renal transplantation. METHODS: Serum samples collected at pre- and different time points posttransplant from 137 live related donor renal transplant recipients were evaluated retrospectively for sMICA levels and for the presence of MICA antibodies. Samples from 30 healthy volunteers were also tested as controls...

Combined and sequential liver-kidney transplantation (CLKT and SLKT) is a definitive treatment in children with end-stage organ failure. There are two major indications: - terminal insufficiency of both organs, or - need for transplanting new liver as a source of lacking enzyme or specific regulator of the immune system in a patient with renal failure. A third (uncommon) option is secondary end-stage renal failure in liver transplant recipients. These three clinical settings use distinct qualification algorithms...

INTRODUCTION: Renal transplant outcomes result from a combination of factors. Traditionally, donor factors were summarized by classifying kidneys as extended criteria or standard criteria. In 2014, the nomenclature changed to describe donor factors with the kidney donor profile index (KDPI). We aim to evaluate the relationship between KDPI and delayed graft function, and the impact KDPI on transplant outcomes for both donor after cardiac death (DCD) and donor after brain death (DBD) ...

OBJECTIVES: Allograft rejection is an important cause of early and long-term graft loss in kidney transplant recipients. Tumor necrosis factor-alpha promotes T-cell activation, the key reaction leading to allograft rejection. Here, we investigated whether serum and urinary tumor necrosis factor-alpha levels can predict allograft rejection. MATERIALS AND METHODS: This study included 65 living related-donor renal transplant recipients with mean follow-up of 26 ± 9 months...

OBJECTIVES: Posttransplant diabetes mellitus is a common and serious metabolic complication after renal transplant. Patients with uremia are known to have abnormal glucose metabolism characterized by insulin resistance and defects in insulin secretion, which are ameliorated to some extent with renal replacement therapy and more so with renal transplant. However, the diabetogenicity of calcineurin inhibitors compounds this state of dysglycemia and promotes the development of diabetes in some patients...

BACKGROUND/AIMS: Male patients with end-stage renal disease suffer from sexual disturbances and infertility. Disturbances in the hypothalamic-pituitary-gonadal axis are one of the causes of this. Decreased testosterone synthesis in Leydig cells of the testes and hyperprolactinemia are common. Kidney transplantation, unlike hemodialysis, normalizes these changes. However, how kidney transplantation affects Sertoli cell function is poorly understood. This study is aimed at investigating the changes in fertility-related hormones in men before, during, and after renal transplantation...

BACKGROUND/AIMS: It has become clear that metformin exerts pleiotropic actions beyond its glucose-lowering agent effect. In this review, we summarise the state of the art concerning the potential renoprotective effects of metformin in vitro, animal models and clinical nephrology. METHODS: A literature search was performed in PUBMED, ScienceDirect, between January 1957 and March 2017 using the following keywords: "metformin," "nephroprotection," "renoprotection," "survival," "renal failure," "chronic kidney diseases," "fibrosis," "polycystic kidney disease" and "microalbuminuria...

In a multicenter, open-label, study, 284 living-donor liver transplant patients were randomized at 30±5 days post-transplant to start everolimus+reduced tacrolimus (EVR+rTAC) or continue standard tacrolimus (TAC Control). EVR+rTAC was non-inferior to TAC Control for the primary efficacy endpoint of treated BPAR, graft loss or death at 12 months post-transplant: difference -0.7% [90%CI -5.2%, 3.7%]; p<0.001 for non-inferiority. tBPAR occurred in 2.2% and 3.6% of patients, respectively. The key secondary endpoint, change in estimated GFR from randomization to month 12, achieved non-inferiority (p<0...

This article examines two questions. (1) If prospective living kidney donors knew of the lifetime risk of end-stage renal disease (ESRD) in their remaining kidney, then would they be as willing to give it up? and (2) What should transplant organizations and physicians be telling those who express an interest in donating a kidney about risk? Based on the principle that prospective donors must be fully informed of the risk, I raise the issue of a possible obstacle to closing the gap between the availability and need of transplantable kidneys...

REVIEW
Vasishta S Tatapudi, Robert A Montgomery
Purpose of Review: Over the past two decades, significant strides made in our understanding of the etiology of antibody-mediated rejection (AMR) in transplantation have put the complement system in the spotlight. Here, we review recent progress made in the field of pharmacologic complement inhibition in clinical transplantation and aim to understand the impact of this therapeutic approach on outcomes in transplant recipients. Recent Findings: Encouraged by the success of agents targeting the complement cascade in disorders of unrestrained complement activation like paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS), investigators are testing the safety and efficacy of pharmacologic complement blockade in mitigating allograft injury in conditions ranging from AMR to recurrent post-transplant aHUS, C3 glomerulopathies and antiphospholipid anti-body syndrome (APS)...

This review is intended to be a guide for the physician to evaluate and prepare a donor / recipient couple for living kidney transplantation. Although it is intended to be exhaustive, it will not be able to respond at all possible and different cases, but it may apply at most of them. Renal transplantation is considered the choice treatment for patients with chronic renal failure and if the kidney transplant is performed pre-emptive it is associated with better organ and patient survival. The main aim of the program is to evaluate the risks of donor and recipient and to ensure the donor safety and well-being...

Objective: Renal transplantation from living related donor is the best treatment option for chronic renal failure with experience for more than 50 years. However, this procedure may expose the health and even the life of otherwise normal individuals to risk. In this prospective study we described the surgical complications of open donor nephrectomies by Clavien grading system. Material and methods: Between May 2002 and December 2014, one hundred and seventy-two potentially healthy kidney donors were admitted to Althawrah General Hospital, Ibn-Sina Hospital and Military Hospital...

BACKGROUND: Monoclonal gammopathy of renal significance denotes a spectrum of hematologic disorders that cause direct or indirect renal damage. CASE PRESENTATION: A 51-year-old man had received a living-donor kidney transplant from his wife in 2008. He had gradual increased proteinuria 4 years later. His renal biopsy results revealed cytoplasmic crystalloid inclusions in the podocytes. No crystalloid inclusion was found in other renal cells. Despite that immunofluorescent examination failed to show light-chain deposition, the serum immuno-electrophoresis revealed monoclonal immunoglobulin-Gκ...

A Japanese woman with a history of Kasai operation for biliary atresia had living-donor liver transplantation at the age of 22. The first episode of refractory HE and late cellular rejection was treated by a high dose of methylprednisolone. The second episode of refractory HE was treated by balloon-occluded retrograde transvenous obliteration for a spleno-renal shunt. However, the third episode of refractory HE occurred 11 years after liver transplantation. The liver cirrhosis and hypersplenism were present with a Child-Pugh score of C-10...

Calcineurin inhibitor (CNI) toxicity leads to ESRD in almost half of long-term survivors after lung transplantation, some of them receiving kidney transplants. Little is known about the outcomes of kidney and lung allograft function following kidney after lung transplantation (KALTPL) in the modern era. We retrospectively analyzed a group of 13 consecutive patients who received a KALTPL with respect to their renal and pulmonary function and immunological evolution over 2 years. We documented a stable evolution of forced expiratory volume in one second (FEV1) after KALTPL in most patients as well as an excellent kidney graft during the 2-year follow-up period...

Due to the increasing number of patients with end-stage renal disease, there is a growing demand for transplants for recipients and donors aged 60 years and older. Using data from the Scientific Registry of Transplant Recipients, we performed survival analyses and multivariate logistic regression to help guide transplant professional decisions regarding the selection of graft type (living vs deceased) and donor age (60-69 vs 70+ years) for recipients aged 60 years and older.
