Clinical Outcomes of C3 Glomerulopathy and IC-MPGN in Russia: Hybrid Retrospective - Prospective Study
100 participantsStarted 2026-02-01
Plain-language summary
The study is planned to study specificity of the clinical course and treatment outcomes of C3 glomerulopathy (C3G) and Immune-complex membranoproliferative glomerulonephritis (IC-MPGN) in patients aged under 18 years and 18 years and older in the Russian population in 2025-2028. The primary objective of the study is to estimate the frequency of complete or partial remission 12 months after morphological verification of the diagnosis. Assessment of demographic, clinical and laboratory, morphological characteristics at diagnosis and their relationship with the disease outcomes, primarily the disease progression and development of chronic renal failure, will allow assessing the efficacy of treatment used in real clinical practice, disease prognosis and factors associated with unfavourable outcomes.
