Brief summary
Henoch-Schonlein purpura nephritis(HSPN) is one of the most common secondary glomerulonephritis in children. A large, prospective, multicenter cohort study is being conducted in three institutions. Eligible Henoch-Schönlein purpura nephritis children will be classified as the experimental group (n=300) and the control group (n=300) based on the interventions they receive. Patients taking Chinese herbal formula will be in the experimental group, and those taking Western medicine will be in the control group. The entire study will last 60 weeks, including a 12-week observation period and a followup at 12 months.
Detailed description
Background: Henoch-Schönlein purpura nephritis involves the renal impairment of Henoch-Schönlein purpura and can easily relapse into life-threatening late nephropathy in severe cases. Although there is a lack of validated evidence for its effectiveness, traditional Chinese medicine is the most commonly used method in China to treat Henoch-Schönlein purpura nephritis. We report the protocol of a prospective cohort trial using traditional Chinese medicine to investigate the effectiveness, safety and advantages for children with Henoch-Schönlein purpura nephritis. Methods/Design: A large, prospective, multicenter cohort study is being conducted in three institutions. Eligible Henoch-Schönlein purpura nephritis children will be classified as the experimental group (n=300) and the control group (n=300) based on the interventions they receive. Patients taking Chinese herbal formula will be in the experimental group, and those taking Western medicine will be in the control group. The entire study will last 60 weeks, including a 12-week observation period and a followup at 12 months. Seven visits will be scheduled for each participant with visits in week 0, week 2, week 4, week 6, week 8, week 10 and week 12. The primary outcomes include the remission rate and the recurrence rate. The secondary outcomes include the urine erythrocyte effectiveness, the urine protein effectiveness, the hormone usage rate, the immunosuppressant usage rate, and the incidence rate of renal failure. Safety outcomes and any adverse reactions will be recorded during the study. Discussion: This study will determine whether the Chinese herbal formula is helpful for treating Henoch-Schönlein purpura nephritis in children. The findings will provide a basis for further confirmatory studies.
