Popis: Background and Aims Rapidly progressive glomerulonephritis (RPGN) encompasses a group of diseases with a common histology in which the absence of treatment progress to end-stage renal disease. Induction treatment includes the use of immunosuppressants, and in certain cases, plasmapheresis. The final objective of this study was to determine the long-term prognosis of the RPGN. Method A retrospective observational study was conducted, including patients diagnosed with RPGN between 2004 and 2019. Baseline epidemiological data and comorbidities were collected, as well as renal function and treatment at the time of diagnosis. During the follow up [median of 42 (5-101 months)], we analyzed the evolution of renal function, mortality and associated factors. Results Forty-three patients (65% women) were included, with a mean age of 70 ± 16 years. At the time of diagnosis, mean creatinine was 4.8 ± 2.6 mg/dl, proteinuria 1094 ± 856 mg/day and 37 patients (86%) presented hematuria Thirty-one patients (72%) presented positivity for antibodies against the neutrophil cytoplasm, 7 (16%) for antibodies against the glomerular basement membrane and 5 (12%) for both. Regarding the induction treatment, 41 patients received cyclophosphamide and corticoids and two patients received rituximab. Seventeen (31%) plasmapheresis were performed with a median of 7 (6-7 sessions). At 6 months, 55% of the patients presented remission (15 patients complete remission and 8 patients partial remission). The median creatinine was 1.9 (1.2-3.1) mg/dl and the proteinuria was 380 (85 -542) mg/day (p Conclusion Initial renal function and 6-month remission predicts mortality in the RPGN.
