[Nephrotic syndrome and Gram-negative sepsis in a patient with strongyloidiasis: a case report].

Strongyloidiasis is caused by a small intestinal nematode with a complex life cycle. In Italy the infection is endemic in rural areas of the Po Valley. The clinical syndrome of S. stercoralis encompasses a broad spectrum of symptoms and signs and, in the immunocompromised host, larvae can migrate to different organs and tissues. Also immune response seems to play a role in the pathogenesis of the disease. We report a case of strongyloidiasis complicated by Gram-negative sepsis and nephrotic syndrome in an immigrant from South America with a normal immune response. Whereas sepsis cleared up quickly, parasitic clearance was obtained only after treatment with ivermectin and nephrotic syndrome was still present three months after the end of treatment.
