Popis: Abstract Background We evaluated the efficacy of different immunosuppressive regimens in patients with primary membranous nephropathy in a large national cohort. Methods In this registry study, 558 patients from 47 centers who were treated with at least one immunosuppressive agent and had adequate follow-up data were included. Primary outcome was defined as complete (CR) or partial remission (PR). Secondary composite outcome was at least a 50% reduction in estimated glomerular filtration (eGFR), initiation of kidney replacement therapies, development of stage 5 chronic kidney disease, or death. Results Median age at diagnosis was 48 (IQR: 37–57) years, and 358 (64.2%) were male. Patients were followed for a median of 24 (IQR: 12–60) months. Calcineurin inhibitors (CNIs) with or without glucocorticoids were the most commonly used regimen (43.4%), followed by glucocorticoids and cyclophosphamide (GC-CYC) (39.6%), glucocorticoid monotherapy (25.8%), and rituximab (RTX) (9.1%). Overall remission rate was 66.1% (CR 26.7%, PR 39.4%), and 59 (10.6%) patients reached secondary composite outcome. Multivariate logistic regression showed that baseline eGFR (OR 1.011, 95% CI: 1.003–1.019, p = 0.007), serum albumin (OR 1.682, 95% CI: 1.269–2.231, p
