Public surveys conducted in many countries report widespread willingness of individuals to donate a kidney while alive to a family member or close friend, yet thousands suffer and many die each year while waiting for a kidney transplant. Advocates of financial incentive programs or "regulated markets" in kidneys present the problem of the kidney shortage as one of insufficient public motivation to donate, arguing that incentives will increase the number of donors. Others believe the solutions lie-at least in part-in facilitating so-called "altruistic donation;" harnessing the willingness of relatives and friends to donate by addressing the many barriers which serve as disincentives to living donation...

BACKGROUND: The majority of kidney transplants are performed in recipients (RTR) over 50; simultaneously their life expectancy is improving. The increasing age and number of RTR is likely to be paralleled by an increase of prostate cancer (PCa) incidence. However, little is known on the optimal management of these patients who represent a therapeutic challenge due to medical and anatomical graft-related issues. METHODS: AMED, Medline and Embase were searched until November 17(th) , 2016 adhering to the PRISMA guidelines and the AMSTAR checklist to investigate oncological and functional outcomes of PCa treatment in RTR...

IRD organs are classified by the Public Health Service to be at above-average risk for harboring human immunodeficiency virus, hepatitis C, and hepatitis B. Traditionally underutilized, there exists even greater reluctance for their use in pediatric patients. We performed a retrospective analysis via the United Network for Organ Sharing database of all pediatric renal and hepatic transplants performed from 2004 to 2008 in the United States. Primary outcomes were patient and graft survival. Proportional hazards regression was performed to control for potentially confounding factors...

We studied the causes and predictors of death-censored kidney allograft failure among 1670 kidney recipients transplanted at our center in the corticosteroid-free maintenance immunosuppression era. As of January 1, 2012, we identified 137 recipients with allograft failure; 130 of them (cases) were matched 1-1 for recipient age, calendar year of transplant and donor type with 130 recipients with functioning grafts (controls). Median time to allograft failure was 29 months (interquartile range 18-51). Physician validated and biopsy confirmed categories of allograft failure were: acute rejection (21%), glomerular disease (19%), transplant glomerulopathy (13%), interstitial fibrosis tubular atrophy (10%), and polyomavirus-associated nephropathy (7%)...

OBJECTIVE: To compare transplant outcomes among elderly (aged ≥60 years) and non-elderly recipients, and to evaluate the acceptability of elderly living donor kidney transplantation in practice after consideration of living donor type. METHODS: We included 830 adult patients with living donor kidney transplantation between 2000 and 2011 in this retrospective cohort study. We compared death-censored graft survival, patient survival, biopsy-proven rejection, complications, and renal function in elderly (n = 119) and non-elderly recipients (n = 278)...

BACKGROUND: Immune responses to tissue-restricted self-antigens are thought to play a role in chronic rejection after solid organ transplantation. De novo development of antibodies (Abs) to vimentin have been reported to be associated with interstitial fibrosis/tubular atrophy after kidney transplant, and it has been suggested that immunoglobulin isotype switching of Abs to vimentin may occur during this process. We aimed to determine the correlation between immunoglobulin isotype switching of Abs to vimentin and development of transplant glomerulopathy (TG) after kidney transplant, and to determine whether citrullinated modification of vimentin is required for de novo anti-vimentin development...

BACKGROUND AND AIM: Data are scanty on allocating simultaneous liver kidney (SLK) based on model for end-stage disease (MELD) score. Diabetes mellitus (DM) and hypertension (HTN) are frequent in cirrhosis patients. We analyzed transplant recipients with DM and/or HTN to compare MELD-based outcomes of SLK to liver transplantation alone (LTA). MATERIALS AND METHODS: Of 13,584 first deceased donor liver transplantation among patients with DM and/or HTN (1530 or 11...

Data related to graft outcomes following posttransplant lymphoproliferative disease (PTLD) in pediatric kidney transplantation are scarce. Data were analyzed retrospectively from 12 children (8 boys) for three years after diagnosis of PTLD, with a loss of follow-up after 2 years in 2/12. In all cases, intensity of immunosuppressive therapy was reduced, with switch from calcineurin inhibitor to a mammalian target of rapamcyin (mTOR) inhibitor in 6 cases. Nine children were treated with 6 doses of rituximab according to the PED-PTLD-2005 protocol, with additional treatment in one child as per protocol...

BACKGROUND: St. Louis encephalitis virus is a mosquito-borne flavivirus that infrequently causes epidemic central nervous system infections. In the United States, blood donors are not screened for St. Louis encephalitis virus infection, and transmission through blood transfusion has not been reported. During September 2015, St. Louis encephalitis virus infection was confirmed in an Arizona kidney transplant recipient. An investigation was initiated to determine the infection source. STUDY DESIGN AND METHODS: The patient was interviewed, and medical records were reviewed...

Systemic sclerosis (SSc) is a connective tissue disease that results in fibrosis in multiple organs. Various animal models for this disease have been developed, both genetic and induced. One of the induced models, sclerodermatous graft-versus-host disease (scl-GvHD), exhibits the main characteristics of SSc, but involves lethal γ-irradiation of recipients. We sought to develop a modified scl-GvHD model. Spleen cells from B10.D2 donor mice were transplanted into immunodeficient Rag-2 recipients on the BALB/c genetic background...

Invasive fungal infections (IFIs) are a significant cause of morbidity in solid organ transplant (SOT) recipients. Common causes among them are Aspergillus, Candida, and Cryptococcus. Antifungal prophylaxis has led to decrease in overall incidence of IFI; however, there is very little decline in the incidence of Cryptococcal infections of SOT recipients because effective prophylaxis is not available against this infectious agent. Spectrum of manifestation of Cryptococcal infection varies in immunocompetent and immunocompromised host with subclinical and self-limiting with lungs being the primary site in immunocompetent and central nervous system as the most common site in an immunocompromised host...

Collapsing glomerulopathy (CG) is a well-recognized distinct morphological pattern of proliferative parenchymal injury leading to rapid graft failure. We conducted a single-center retrospective study to evaluate the prevalence, clinicopathological features, and prognosis of CG in renal transplant recepient. We analyzed 2518 renal allograft biopsies performed from 2007 to 2015 and correlated their clinicopathological features. The prevalence of CG was 0.83% (21 out of 2518) of allograft biopsies with a higher prevalence of 1...

BACKGROUND: The development of spontaneous kidney transplant tolerance has been associated with numerous B cell-related immune alterations. We have previously shown that tolerant recipients exhibit reduced B cell receptor (BCR) signalling and higher IL-10 production than healthy volunteers. However, it is unclear whether CD4T cells from tolerant recipients also display an antiinflammatory profile that could contribute to graft maintenance. METHODS: CD4T cells were isolated from kidney transplant recipients who were identified as being tolerant recipients, patients with chronic-rejection or healthy volunteers...

Healthcare reimbursement is increasingly tied to value instead of volume, with special attention paid to resource-intensive populations such as patients with renal disease. To this end, Medicare has sponsored pilot projects to encourage providers to develop care coordination and population health management strategies to provide quality care while reducing resource utilization. In this Personal Viewpoint essay, we argue in favor of expanding one such pilot project-the Comprehensive ESRD Care (CEC) initiative-to include patients with advanced chronic kidney disease and kidney transplant recipients...

HCV infection is associated with reduced patient survival following combined liver-kidney transplantation (LKT). The aim of this study was to assess the efficacy and safety of second generation direct active antiviral (DAAs) in this difficult-to-treat population. The ANRS CO23 CUPILT study is a prospective cohort including transplant recipients with recurrent HCV treated with DAAs. The present work focused on recipients with recurrent HCV following LKT. The study population included 23 patients. All patients received at least one NS5B inhibitor (Sofosbuvir) in their antiviral regimen an average of 90 months after LKT...

OBJECTIVE: We evaluated whether a short-term course with synbiotics may lower plasma p-Cresol concentrations in kidney transplant patients (KTRs) who accumulate this uremic toxin both because of increased production by their dysbiotic gut microbiome and because of reduced elimination by the transplanted kidneys. METHODS: Thirty-six KTRs (29 males, mean age 49.6 ± 9.1 years) with transplant vintage > 12 months, stable graft function, and no episode of acute rejection or infection in the last 3 months were enrolled in this single-center, parallel-group, double-blinded, randomized (2:1 synbiotic to placebo) study...

The immunosuppressive state in organ transplantation leads to infectious complications responsible for high mortality rate. Fungal infections account for 5% of all infections in Renal Transplantation (RT) recipients. Aspergillus species are filamentous fungi frequently causing fungal infections in RT recipients. Lungs and paranasal sinuses are the usual portal of entry from where it disseminates to other organs. Here, we are reporting a case of 14-year-old boy with RT from mother's kidney, who had atypical presentation of isolated cerebral aspergillosis at 19 months post-transplant without identified portal of entry...
