About

This non-inferiority study aims to compare the efficacy of Prednisone combined with Huaiqihuang Granule against Prednisone combined with Levamisole in the treatment of primary nephrotic syndrome (PNS) in children.

Full description

Nephrotic syndrome (NS) is the most frequent glomerular disease in children, with an incidence of 1.15-16.9 per 100,000 children. Children present with the disease at a median age of 2-3 years, and it is twice as common in boys. More than 90% of children who present with NS respond to corticosteroid treatment, and current practice is to treat most patients empirically with prednisone. However, after initial successful treatment, around 80% of children with steroid sensitive NS have disease relapses requiring further courses of prednisone. About 50% of patients develop frequent relapsing or steroid dependent. Further, the long-term use of corticosteroids is associated with numerous side effects, like obesity, diabetes and hypertension.

Traditional Chinese medicine plays a unique role in the enhancement of immune function and kidney function. Huaiqihuang granule is composed of Trametes robiniophila Murr, Fructus Lycii, and Polygonatum sibiricum. It has been used for the treatment of primary nephrotic syndrome (PNS) in China. Previous studies showed Huaiqihuang granule combined with corticosteroids could significantly decrease relapse and infection rates of PNS and were well tolerated by children. This non-inferiority study aims to compare the efficacy of Prednisone combined with Huaiqihuang Granule against Prednisone combined with Levamisole in the treatment of PNS in children.

In this study, about 20 research centers will participate. A total of 402 participants will be divided into two groups (the intervention group and control group) at a ratio of 1:1. The intervention group will receive Prednisone, Huaiqihuang granule and Levamisole placebo, and the control group will receive Prednisone, Levamisole and Huaiqihuang granule placebo. The planned length of patient recruitment enrolment will be 2 years and the total length of visits be 6 months. After enrollment, participants will be followed up until the end of the study (6 months), second relapse, develop as steroid-resistant, lost to follow-up, withdrawal from the study for any reason, or die, whichever occurs first.
