Background. To explore the curative effect of Shuangshen Decoction combined with immunological preparations in the treatment of pediatric nephrotic syndrome and its influence on concurrent infection and recurrence rate. Methods. Ninety children with nephrotic syndrome were divided into the routine group and the combined group. The routine group received conventional treatment and immune agents, and the combined group was treated with Shuangshen Decoction on the basis of the routine group. The clinical indexes of the two groups were analyzed and followed up. The infection rate and recurrence rate were calculated. Results. The TCM syndrome scores in the combined group were significantly lower than those in the routine group. The total effective rate of the combined group was significantly higher than that of the routine group. The recurrence rate and infection rate of the combined group were significantly lower than those of the routine group. The incidence of adverse reactions in the combined group was significantly lower than that in the routine group. Conclusion. Shuangshen Decoction combined with immune preparations is effective in treating pediatric nephrotic syndrome and can reduce the incidence of adverse reactions, infection rate, and recurrence rate.
