Minimal change nephrotic syndrome in association with strongyloidiasis.
Although parasitic infections have been known to be associated with immune complex-mediated glomerular lesions, strongyloidiasis-related glomerulopathy has not been well documented. We report a patient with delayed-recognized disseminated strongyloidiasis who developed nephrotic syndrome 3 months after the beginning of the manifestations related to strongyloidiasis. A kidney biopsy showed minimal change disease. We treated strongyloidiasis and hesitated to give steroid therapy for the treatment of minimal change nephrotic syndrome (MCNS) because of the risk of aggravation of Strongyloides stercoralis infection. Surprisingly, resolution of heavy proteinuria occurred after anthelmintic therapy with ivermectin. This case suggests a possible causal relationship between S. stercoralis infection and MCNS. In addition, a review of another 4 cases previously reported in the literature demonstrates the importance of detecting underlying S. stercoralis infection in patients with nephrotic syndrome since steroid therapy can cause hyperinfection or disseminated strongyloidiasis, and which may lead to fatal outcome.
