ALB and systemic lupus erythematosus: We performed an analysis on a cohort of SLE patients with LN to determine if serum albumin can serve as an early predictor of combined proteinuria recovery (complete proteinuria recovery [CPR] + partial proteinuria recovery [PPR]) and primary efficacy proteinuria recovery (PEPR) at 6–9 and 18–21 months in LN patients receiving standard treatment.
