Disseminated Strongyloides stercoralis infection.

A case of disseminated S stercoralis is an immunosuppressed patient manifested with diarrhea, a rash, and progressive respiratory insufficiency. The parasites were eradicated with thiabendazole despite continued steroid therapy, and the patient survived the hospitalization. The characteristics of S stercoralis allow it to be harbored within a host for prolonged periods of time, only to disseminate once cell-mediated immunity is suppressed. A diagnosis of strongyloidiasis should be considered in an immunocompromised patient with a petechial rash. Prompt diagnosis and initiation of thiabendazole therapy provides the greatest opportunity for patient survival. Secondary bacterial infections should be aggressively sought. Mortality from disseminated strongyloidiasis approaches 80%.
