Abstract:
Objective To compare the efficacy and safety of leflunomide (LEF) combined with medium/low dose corticosteroids and full dose of corticosteroids in the treatment of IgA nephropathy. Method Primary IgAN patients diagnosed by renal biopsy with 18?65 years old and eGFR≥30 ml·min?1·(1.73 m2)?1 and proteinuria>0.5 g/24 h were enrolled in a prospective controlled clinical study. They were randomly divided into leflunomide combined with medium/low dose corticosteroids (LEF group) and corticosteroids alone (steroid group). The primary outcomes were (1) end stage renal disease or dialysis (2) 50% increase in serum creatinine above the baseline. Secondary outcome was the remission of proteinuria. Results Ninety patients completed the follow?up. The 24?hour proteinuria at baseline were 2.00(1.10, 2.88) g and 1.87(1.13 ,3.08) g in LEF group and steroid group respectively. Compared with baseline, it was significantly decreased in both groups at 6 months [0.30(0.11, 0.93) g, 0.30(0.14, 1.33) g] and 12 months [0.30(0.09, 0.82) g, 0.32(0.14, 0.66) g], (P<0.05). Estimated glomerular filtration rate (eGFR) at baseline, 6 months and 12 months were (80.39 ± 28.56), (87.12±28.70) and (88.20±30.26) ml·min-1·(1.73 m2)-1. It was decreased in steroid group (P<0.05), while no significant difference was detected in LEF group[baseline (87.63 ± 27.35), 6 months (86.91 ± 32.45), 12 months (90.06 ± 30.00) ml·min-1·(1.73 m2)-1, P>0.05]. At 6 and 12 months, there was no significant difference in terms of 24?hour proteinuria, serum creatinine and eGFR (CKD?EPI) between groups (P>0.05). There was no statistically significant difference in adverse events between groups during the treatment (9/40 cases in LEF group and 11/50 cases in steroid group, P>0.05). The average follow?up was 79 months, and there was no difference in the renal prognosis between the two groups. Multivariate Cox regression analysis revealed that serum creatinine at baseline and renal interstitial inflammatory cell infiltration predicted the risk of the progress of IgA nephropathy. Conclusion Leflunomide plus medium/low dose corticosteroids has a similar effect as full dose of corticosteroids in IgA nephropathy and does not increase the risk for adverse events during the treatment.
