Abstract:
Objective To investigate the correlation between food intolerance and Henoch-Sch(o)nlein purpura (HSP) in children and the efficacy of food forbidden or alternative therapy. Methods The levels of IgG against several common food in serum obtained from 40 children with HSP were measured by ELISA. The efficacy of food forbidden or alternative food therapy was assessed after 3 months. Results Total positive rate of serum food-intolerant IgG antibodies in HSP children was 92.5%. Among these 14 intolerant foods, the positive percentage of egg was the highest (33.8%), followed by tomato (14.9%), milk (13.5%) and morrhua (12.2%). Significant differences of the sort and degree of food intolerance existed among different age groups (t=2.257, P=0.045), but not between boys and girls (t=1.053, P=0.315), city and countryside (t= 1.388, P=0.193). There was no linear correlation between total food intolerance and serum IgG level (t=0.793, P=0.445). Food intolerance had no direct relation to immune complex deposition in kidneys of HSP nephritis (r =-0.262, P =0.387). The efficacy of adjusting diet was 95% . Conclusions HSP is closely related to food intolerance. Egg is the most common intolerant food. Food forbidden or alternative therapy shows acceptable efficacy in the treatment of most Henoch-Sch(o)nlein purpura children.
