OBJECTIVES To assess the long term outcomes of transplantation using expanded criteria donors (ECD; donors aged ≥ 60 years or aged 50-59 years with vascular comorbidities) and assess the main determinants of its prognosis. DESIGN Prospective, population based cohort study. SETTING Four French referral centres. PARTICIPANTS Consecutive patients who underwent kidney transplantation between ...
Allograft thrombosis is a devastating early complication of renal transplantation that ultimately leads to allograft loss. We report here on our experience of nine cases of immediate re-transplantation following early kidney transplant thrombosis at a single centre between January 1990 and June 2009. The mean age was 42.9 years at time of transplant. For seven patients, the allograft thrombosis...
Cytomegalovirus (CMV) infection is a frequent complication of early posttransplantation. This study examines its impact on chronic allograft changes, long-term graft loss, and patient survival. We studied 594 patients who had protocol biopsies at 6 wk, and 3 and 6 mo posttransplantation. Chronic allograft changes were evaluated according to the updated Banff classification [interstitial fibrosi...
BACKGROUND Islet transplantation may potentially cure type 1 diabetes mellitus (T1DM). However, immune rejection, especially that induced by the alloreactive T-cell response, remains a restraining factor for the long-term survival of grafted islets. Programmed death ligand-1 (PD-L1) is a negative costimulatory molecule. PD-L1 deficiency within the donor heart accelerates allograft rejection. He...
PURPOSE To examine the role of the CD28-CD80-CD86 pathway of T-lymphocyte costimulation in corneal allograft rejection and the effect of blockade of that pathway on graft survival. METHODS Kinetics of CD80 and CD86 expression in the cornea and draining lymph nodes were examined by RT-PCR and immunohistochemistry in untreated allograft recipients in a high-responder rat model. The effect of bl...
