ABSTRACT
Sera and peripheral blood mononuclear cells (PBMC) were collected from 42 children with simple idiopathic nephrotic syndrome (INS) aged from 1.5 to 14 years and 28 age and sex-matched healthy children. The levels of IgE in serum and interleukin 4 (IL-4) in supernatant of PHA-activated PBMC were tested by ELISA. A significantly high incidence of allergic diseases was noted in INS children and their first-degree relatives, and there was a close association between atopy and INS. Besides, the levels of IgE and IL-4 were increased in nephrotic state (P < 0.001 both). IgE normal and IL-4 slightly lower in remission state (P < 0.2, P < 0.01 respectively). A positive correlation was noticed between IL-4 and IgE, and between IL-4 and 24-hour proteinuria (r = 0.472, r = 0.562; P < 005, P < 0.01 respectively). These showed a close association between atopy and INS. Both IL-4 and IgE, the important mediators in atopy, showed abnormal change in patients. The increased IL-4 production of T cells might account for the elevated serum IgE level. IL-4 may have a pathogenetic role in INS, but it still remains speculative.
