Abstract

Panel-reactive antibodies (PRA) are a major obstacle to kidney transplantation (KTx). It is not completely clear why only some patients develop PRA, whereas others do not. We hypothesized that other factors, such as autoimmune diseases involving the kidney, might be a trigger for PRA development. We reviewed the original diseases that led to renal failure and their possible role in PRA development. Charts of 270 patients on the active waiting list for KTx were reviewed for complete demographics, presence of PRA, peak PRA level, first KTx or retransplantation, original disease, blood transfusions, pregnancy and rejection. Patients were divided into group 1 (PRA >10%) and group 2 (PRA <10%). There was a significantly higher proportion of patients in group 1 with autoimmune diseases than in group 2. The same proportion was found significant for all of the patients as well as for the patients listed for the first KTx (new patients). Previous KTx has significant impact on both class I and II peak PRA levels when compared with new patients who are already sensitized. A subanalysis of retransplantation showed patients with autoimmune disease (54%) have more graft loss due to rejection compared with nonautoimmune disease (43%). There is an association between high PRA level and autoimmune diseases causing renal failure regardless of the previous KTx status. Besides the risk of recurrence, autoimmune disease seems to affect the risk of graft loss due to rejection.
