Strongyloides stercoarlis--hyperinfection.

A case of severe Strongyloides stercoralis infection is described in a patient with renal failure due to bilateral cortical necrosis. Because thiabendazole, the drug of choice in strongyloidiasis, is primarily excreted by the kidneys, alternative therapy with a mebendazole was instituted. Although the patient eventually died as a result of the renal failure, successful therapy with mebendazole was well demonstrated.
