ABSTRACT

Objective To study the relationship between the activity of interleukin-4 and interferon-? with steroid effect in children with primary nephrotic syndrome before initiation of steroid therapy. Methods The activity of interleukin-4 and interferon-? in the supernatants of monocytes cell cultures activated with phytohemagglutinin was assessed with enzyme-linked immunosorbentassay in 31 children with primary nephrotic syndrome before iniatiation of steroid therapy. After steroid treatment for 8 weeks, data of steroid sensitivity and resistance were analyzed. Results Before initiation of steroid treament, in steroid sensitivity children with primary nephrotic syndrome an increased proliferative response of interleukin-4 was found (P0.05). Conclusion The activity of interleukin-4 is a useful tool for evaluating the likelihood of steroid sensitivity in children with primary nephrotic syndrome.
