Abstract :

Background: IgA nephropathy (IgAN) is the third most frequent cause of renal graft loss among patients with primary glomerulonephritis. Objectives: To assess clinical and laboratorial profile of patients with pre and/or post transplant IgAN, in addition to patient and graft survival in both groups. Design: Data from 146 patients who had received a renal transplant were retrospectively collected and were divided in two groups: group 1-patients with biopsy-documented IgAN as the underlying native kidney disease (n 1�?4 128); group 2-patients who developed post-transplant IgAN independent of the underlying disease (n 1�?4 18). Participants: Patients submitted to renal transplantation (1998��?2010) with pre and/or post transplant IgAN. Measurements: Clinical and laboratorial evaluation of renal function of 146 post transplant IgAN patients. Results: Recipients and deceased donors exhibited a higher degree of HLA compatibility (1.0 vs. 2.5 mismatches for groups 1 and 2, respectively). The main post-transplant IgAN presentation was haematuria associated with non-nephrotic proteinuria (44.4%). A histological pattern of focal segmental glomerulosclerosis was observed in 59.2% of biopsy samples. The 10-year patient survival was 93.5% in group 1 and 100% in group 2, and the graft survival rates were 58.5 and 87.2%, respectively. Conclusion: The rate of post-transplant IgA diagnosis in our case series was 11%, and IgAN was diagnosed late in the course of transplantation. In most cases, IgAN manifested as haematuria and non-nephrotic proteinuria, without renal graft dysfunction, and this picture might explain late indication of graft biopsies. The 10-year patient survival rates were excellent.
