A very low thymus function identifies patients with substantial increased risk for long-term mortality after kidney transplantation.


ABSTRACT: Background:End-stage renal disease is associated with premature ageing of the T cell immune system but inter-individual variation is substantial. The hypothesis was tested that advanced immunological T cell ageing assessed by peripheral T cell differentiation increases the long-term mortality risk after renal transplantation. Results:Circulating T cells of 211 recipients of a kidney from a living donor were analyzed before and in the first year after transplantation. The number of CD31-positive naive T cells (as a marker for recent thymic emigrants) and the differentiation status of the memory T cells was assessed. Thirty recipients died during follow-up of at least 5?years. Absolute numbers of naive CD4+ (living:258 cells/?l vs. deceased:101 cells/?l, p?
