Lymphangiogenesis in a mouse model of renal transplant rejection extends life span of the recipients

Renal allograft rejection can be prevented by immunological tolerance, which may be associated with de novo formed lymphatic vessels in the donor kidney after transplantation in man. A suitable mouse model of renal allograft rejection in which lymphangiogenesis can be deliberately induced in the graft is critical for elucidating the mechanisms responsible for the association between attenuated transplant rejection and abundance of lymphatic vessels. Here we describe the development of a novel mouse model of rapid renal transplant rejection in which transgenic induction of lymphangiogenesis in the immune-incompatible graft greatly extends its survival time.

AbstractHLA eplet mismatch load has been suggested as an improvement to HLA antigen mismatch determination for organ selection. Given that eplet mismatches are determined based on amino acid sequence difference among HLA alleles, and that the frequency of HLA alleles varies between racial groups, we investigated the correlation between eplet mismatch load and allograft outcomes in 110 pediatric kidney transplant recipients who received their first organ from a donor of the same race (SRT) versus a donor of a different race (DRT). Adjusted modified Poisson regression was used to assess the interaction between eplet mismatch...

Membranous nephropathy (MN) is a common cause of nephrotic syndrome after transplantation and is associated with an increased risk of allograft loss. MN may occur either as a recurrent or as a de novo disease. As in native kidneys, the pathophysiology of the MN recurrence is in most cases associated with antiphospholipid A2 receptor antibodies. However, the posttransplant course has some distinct features when compared with primary MN, including a lower chance of spontaneous remission and a greater requirement for adjuvant immunosuppressive therapy to induce complete remission. Although the efficacy of rituximab in primary...

Predicting early acute rejection (EAR) at the time of transplant is important to risk-stratify patients and titrate immunosuppression accordingly. We performed whole-blood RNA sequencing at the time of transplant in 235 kidney transplant recipients enrolled in a prospective-cohort study [one discovery set (N=81), two validation sets (N=74 and N=8...

CONCLUSIONS: We found excellent long-term renal allograft survival rates in patients with systemic lupus erythematosus and granulomatosis with polyangiitis, with secondary malignancy rates similar to those shown in recipients without autoimmune diseases. These findings provide clinicians with long-term data on transplant recipients with end-stage renal failure due to systemic inflammatory conditions. PMID: 31580235 [PubMed - as supplied by publisher]

Abstract Delayed graft function (DGF) is a form of acute renal failure which results in increased post-transplantation allograft immunogenicity and risk of acute rejection episodes in addition to decreased long-term survival. Its incidence and risk factors have been extensively studied, especially after deceased donation. Until now, only few data has been  published on DGF in living donor kidney transplant recipients. The present study was performed to investigate the frequency and risk factors of DGF among living- kidney transplant recipients. In this retrospective study, data had been collected from ex...

Authors: Agrawal N, Garg N, Adapa S, Cardarelli F Abstract Arteriovenous graft in the thigh is used not infrequently for hemodialysis. Outcomes with this lower extremity dialysis access are generally comparable to upper extremity access and superior to long-term catheter use. However, it could have significant implications in a patient getting a kidney transplant. Here we describe a case of thigh arteriovenous graft causing kidney allograft dysfunction in a new transplant recipient, and this resolved with graft ligation.
