Transplant candidates have advanced chronic disease, which often leads to muscular and respiratory impairment contributing to reduced quality of life and daily life activities, and these patients are therefore referred to physiotherapy service. Because of this, it is necessary to know the epidemiologic and functional profile for a better physiotherapeutic approach. Inpatients of kidney, liver, heart, lung and multivisceral transplantation programs were followed up for 1 year. A comparative analysis between groups was performed, taking into account hospital stay time and functional independence measure (FIM)...

OBJECTIVES: To determine whether solid organ transplant (SOT) patients are at higher risk of developing complications after inflatable penile prosthesis (IPP) implantation. METHODS: We retrospectively reviewed outcomes data for all patients with SOT who underwent IPP placement at our institution. A cohort of age-matched IPP recipients without SOT were used as controls. RESULTS: We identified 26 patients who underwent SOT and IPP between 1999-2015, and 26 controls...

The final strategies to care patients with end-stage renal fibrosis rely on dialysis and kidney transplantation. Because such treatments are invasive and cause health problems eventually, it is necessary to develop new therapeutic strategies for delaying the disease progress. We here searched for cytokines showing an anti-fibrotic activity in cell-based experiments. Cystatin C (CST3) and Growth differentiation factor 15 (GDF15) were identified to have anti-fibrotic activities in a cytokine array screening. In primary fibroblasts isolated from the mouse kidneys subjected to ureteral obstruction-induced fibrosis, each cytokine induced apoptotic cell death and reduced collagen production...

Late allograft loss in kidney transplant recipients remains a common problem and is associated with high mortality and morbidity. The management of patients with a failed kidney allograft includes a few major dilemmas: when to start dialysis, what is the optimal management regarding immunosuppression, and should an allograft nephrectomy be performed. In suitable candidates for a repeated transplantation there are additional matters to take in consideration. In this review we will discuss these dilemmas by providing an overview of current evidence and gaps in our knowledge...

CRISPR is a nuclease guidance system that enables rapid and efficient gene editing of specific DNA sequences within genomes. We review applications of CRISPR for the study and treatment of kidney disease. CRISPR enables functional experiments in cell lines and model organisms to validate candidate genes arising from genetic studies. CRISPR has furthermore been used to establish the first models of genetic disease in human kidney organoids derived from pluripotent stem cells. These gene-edited organoids are providing new insight into the cellular mechanisms of polycystic kidney disease and nephrotic syndrome...

Beta cell replacement by pancreas or Langerhans islets transplantation is the only way to restore glucose homeostasis in type 1 diabetic patients. The counterpart is the need for long-term immunosuppression. These transplantations are therefore mainly indicated for patients candidates for kidney transplantation and for patients with poor quality of life due to unstable diabetes with life-threatening hypoglycemic events. Both beta cell replacement techniques have different benefits and risks and should be adapted to each type 1 diabetic patient...

In December of 2014, the new Kidney Allocation System (KAS) for deceased donor kidney transplant was implemented in the US. One of the stated goals of the KAS was to decrease the well-documented disparities in access to kidney transplant for underrepresented racial groups, in part by allowing for the allocation of A2 subtype kidneys to type B recipients with low anti-A antibody titers given that the majority of type B patients represent ethnic and racial minorities. On first glance, this policy was a success...

BACKGROUND: A prolonged living kidney donor evaluation may result in worse outcomes for transplant recipients. Better knowledge of the duration of this process may help inform future donors and identify opportunities for improvement. STUDY DESIGN: 1 prospective and 1 retrospective cohort study. SETTING & PARTICIPANTS: At 16 Canadian and Australian transplantation centers (prospective cohort) and 5 Ontario transplantation centers (retrospective cohort), we assessed the duration of living kidney donor evaluation and explored donor, recipient, and transplantation factors associated with longer evaluation times...

Preformed anti-human leukocyte antigen (HLA) antibodies may be present in the blood of kidney transplant candidates. The production of these antibodies may occur in the post-transplant period, with the possible development of donor-specific antibodies (DSA). Luminex-based tests, such as the single antigen (SA) assay and the Luminex crossmatch (Xm-DSA) assay are the most commonly used tools to detect anti-HLA antibodies, due to their high sensitivity and specificity. This cross-sectional study aimed to compare the findings of two methods for the detection of DSAs after kidney transplant: SA and Xm-DSA...

Living donor kidney transplantation is the most promising way to avoid or minimize the amount of time a recipient spends on dialysis before transplantation. We studied 887 living kidney donors at five transplant centres in Ontario, Canada who started their evaluation and donated between April 2006 and March 2014. Using a series of hypothetical scenarios, we estimated the impact of an earlier living donor evaluation completion and donation on the number pre-emptive transplants, the time spent on dialysis, healthcare cost savings from averted dialysis costs (CAD $2016), and the number of additional transplants...

We reported previously on the widespread occurrence of anti-HLA alloantibodies of the IgA isotype (anti-HLA IgA) in the sera of solid-organ re-transplantation (re-tx) candidates (Arnold et al., ). Specifically focussing on kidney re-tx patients, we now extended our earlier findings by examining the impact of the presence and donor specificity of anti-HLA IgA on graft survival. We observed frequent concurrence of anti-HLA IgA and anti-HLA IgG in 27% of our multicenter collective of 694 kidney re-tx patients...

Purpose: The number of simultaneous liver-kidney transplants (SLKT) performed in the USA has been rising. The Organ Procurement and Transplantation Network implemented a new policy governing SLKT that specifies eligibility criteria for candidates to receive a kidney with a liver, and creates a kidney waitlist "safety net" for liver recipients with persistent renal failure after transplant. This review explores potential impacts for liver patients and the kidney waitlist. Recent Findings: Factors that have contributed to the rise in SLKT including Model for End-stage Liver Disease (MELD)-based allocation, regional sharing for high MELD candidates, and the rising incidence of non-alcoholic steatohepatitis will continue to increase the number of liver transplant candidates with concurrent renal insufficiency...

BACKGROUND: The proportion of patients with kidney failure at time of liver transplantation is at an historic high in the United States. The optimal timing of kidney transplantation with respect to the liver transplant is unknown. METHODS: We used a modified cost-effectiveness analysis to compare four strategies: the old system ("pre-OPTN"), the new Organ Procurement Transplant Network (OPTN) system since August 10, 2017 ("OPTN"), and two strategies which restrict simultaneous liver-kidney transplants ("safety net" and "stringent")...

BACKGROUND: Preemptive kidney transplants result in better outcomes and patient experiences than transplantation after dialysis onset. It is unknown how often a person initiates maintenance dialysis prior to living kidney donor transplantation when their donor candidate evaluation is well underway. METHODS: Using healthcare databases, we retrospectively studied 478 living donor kidney transplants from 2004-2014 across 5 transplant centres in Ontario, Canada where the recipients were not receiving dialysis when their donor's evaluation was well underway...

BACKGROUND: Existing risk adjustment models for solid organ transplantation omit socioeconomic status (SES). With limited data available on transplant candidates' SES, linkage of transplant outcomes data to geographic SES measures has been proposed. We investigate the utility of county SES for understanding differences in pediatric kidney transplantation (KTx) outcomes. METHODS: We identified patients < 18 years of age receiving first-time KTx using United Network for Organ Sharing registry data in two eras: 2006-2010 and 2011-2015, corresponding to periods of county SES data collection...

BACKGROUND: Kidneys from deceased donors are being used to meet the growing need for grafts. However, delayed graft function (DGF) and acute rejection incidences are high, leading to adverse effects on graft outcomes. Optimal induction intervention should include both renal structure injury repair and immune response suppression. Mesenchymal stem cells (MSCs) with potent anti-inflammatory, regenerative, and immune-modulatory properties are considered a candidate to prevent DGF and acute rejection in renal transplantation...

BACKGROUND: Whether patients waitlisted for a second transplant after failure of a previous kidney graft have higher mortality than transplant-näive waitlisted patients is uncertain. METHODS: We assessed the relationship between a failed transplant and mortality in 3851 adult KT candidates, listed between 1984-2012, using a competing risk analysis in the total population and in a propensity score-matched cohort. Mortality was also modeled by inverse probability weighting (IPTW) competing risk regression...

Blood group B candidates, many of whom represent ethnic minorities, have historically had diminished access to deceased donor kidney transplantation (DDKT). The new national kidney allocation system (KAS) preferentially allocates blood group A2/A2B deceased donor kidneys to B recipients to address this ethnic and blood group disparity. No study has yet examined the impact of KAS on A2 incompatible (A2i) DDKT for blood group B recipients overall or among minorities. A case-control study of adult blood group B DDKT recipients from 2013-2017 was performed, as reported to the Scientific Registry of Transplant Recipients...

One of the most important prognostic factors in heart failure patients is physical capacity. Patients with very poor physical performance and otherwise eligible, may be listed as candidates for heart transplantation (HTx). After such surgery, life-long immunosuppression therapy is needed to prevent rejection of the new heart. The dark side of immunosuppression is the increased risk of infections, kidney failure, cancer and advanced atherosclerosis (cardiac allograft vasculopathy), with the two latter conditions as the main causes of later mortality...
