High urinary interleukin‐8 levels is associated with poor prognosis in idiopathic membranous nephropathy

Abstract Biomarkers required to assess accurately the prognosis of idiopathic membranous nephropathy (IMN) are still unavailable. A retrospective study on 156 IMN patients showed only urinary IL‐8 was associated with the achievement of initial complete remission (CR) in IMN patients. A urinary IL‐8 level of less than 61.25 pg/mL was more sensitive for prediction of CR in IMN patients. Therefore, urinary IL‐8 may be a potential biomarker for evaluating short‐term prognosis of IMN patients.
