Strongyloidiasis as a possible cause of nephrotic syndrome.

Chronic strongyloidiasis is a mild disease and has never been reported to be associated with nephrotic syndrome. Disseminated strongyloidiasis is known to have high mortality, but it frequently is not diagnosed until autopsy. We report a patient with nephrotic syndrome developing disseminated strongyloidiasis after steroid therapy. The findings in renal biopsy, the time course of the development, and resolution of nephrotic syndrome after thiabendazole treatment suggested a possible causal relationship between chronic strongyloidiasis and nephrotic syndrome. The case also demonstrated the importance of early diagnosis in disseminated strongyloidiasis and the good clinical outcome of early treatment before the development of organ failure.
