The mean age was 35.1 years. The male:female ratio was 1:1. At the time of renal biopsy, mean proteinuria was 1.32 ± 1.50 (SD) g/day. Severe proteinuria (>3.5 g/day) was observed in 10 patients (4.8 %). During the follow-up period, 154 (74.0 %) of the 208 patients were given ACEIs or ARBs. Among the four therapy groups, there were significant differences in eGFR (P = 0.001),

proteinuria (P < 0.001), the dialysis induction risk (P = 0.001), and observation selleck screening library period (P < 0.001). No difference was observed in the sex ratio, age, hematuria, and use of ACEIs or ARBs. eGFR was significantly lower in the TSP group than in the T and TOS groups. Proteinuria was significantly higher in both TOS and TSP JQ1 datasheet groups than in the T and N groups. The distribution of patients for dialysis induction risk was this website significantly different among the four groups, with the T and TOS groups having more patients with low risk than the TSP groups.
