Background/Aims: The present study aimed to explore the equivalence of CHL and tacrolimus (TAC), despite reports regarding the efficacy and safety of TAC in treating SRNS patients. Methods: A retrospective cohort study of CHL or TAC treatment was performed by collecting the medical records of SRNS patients with a pathological classification of focal segmental glomurular sclerosis (FSGS) or membranous nephropathy (MN) from December 2008 to December 2014 in a 3A grade hospital in southern China. The treatment regimen includes 6 months of induction therapy and a subsequent 6 to 30 months of maintenance therapy, which were evaluated by the scheduled follow-up and the detection of proteinuria and serum creatinine levels. The treatment outcomes were classified as complete remission, partial remission or no remission. Results: In a total of 146 SRNS patients, CHL treatment showed a higher proportion of complete remission (27.8% vs 14.9%) or partial remission (52.8% vs 37.8%) compared to TAC treatment (P < 0.10) at the stage of induction therapy. The CHL treatment of SRNS patients with FSGS showed better efficacy than treatment of the TAC group, but the difference of efficacy in the pathological type of MN between CHL and TAC group was not significant (P > 0.10). During maintenance therapy, the difference between the CHL and TAC groups was not significant in the SRNS patients with FSGS or MN (P > 0.10). In addition, the difference of adverse effects between CHL and TAC group was not significant (P > 0.10), although there was a slightly higher proportion of nausea and vomiting in the CHL group. Conclusion: The non-inferior efficacy of CHL treatment on the SRNS patients with FSGS or MN compared to TAC treatment, which highlighted CHL can be considered to be alternative treatment for SRNS patients in the clinical setting.
