dc.description.abstractBackground: Little data are available concerning post-transplantation glomerulonephritis (PTx-GN) and its prognostic factors associated with graft outcomes.Methods: We retrospectively evaluated patients with de novo and recurrent PTx-GN to identify the factors associated with their negative impact on graft and patient outcomes. PTx-GN was diagnosed in 55 patients, wherein 17 (31%) had recurrent glomerulonephritis (GN) and 16 (29%) had de novo.Results: Our enrolled population consisted of 34 +/- 13.7-yr-old male patients (72%), on hemodialysis for a median of 18 months (0-204) and mainly grafted from living donors (76%). the median onset time of proteinuria and hematuria was 50 d (10-2160) and 30 d (4-1170), respectively. One-yr graft survival rates after PTx-GN diagnosis was 64%. the most frequent de novo GN was membranous GN (26%), while focal segmental glomerulosclerosis was the most frequent recurrent GN (41%), with a very early onset (median of three months). One-yr graft survival was better in the recurrent disease than in the de novo patients, 76% vs. 55% (p = 0.24). the best predictor factors that correlated with graft survival were: proteinuria < 3.5 g [relative risk (RR) = 0.24, p = 0.017], serum creatinine below 2.0 mg/dL (RR = 0.06, p = 0.016) at the time of biopsy and the use of angiotensin-converting enzyme inhibitors (ACEI) (RR = 0.12, p = 0.005). the use of ACEI markedly improved one-yr graft survival rates (92% vs. 47%, p < 0.001).Conclusion: PTx-GN has a strong negative impact on kidney graft survival. de novo GN appears to have a poorer prognosis than the recurrent type. Patients who used ACEI showed a better survival rate in the follow-up.en
