ABSTRACT
Strongyloides stercoralis is an intestinal nematode endemic to tropical and sub-tropical regions. Although infection is typically asymptomatic or self-limited, immunocompromised individuals can develop a severe form of disease marked by hyperinfection. Pulmonary involvement accompanies hyperinfection in a majority of cases, though manifestations range from asymptomatic infiltrates to diffuse alveolar hemorrhage (DAH) and respiratory failure. When complicated by DAH, the hyperinfection syndrome is usually fatal. We report a case of a 65-year-old Guatemalan woman with chronic inflammatory demyelinating polyneuropathy (CIDP) treated with chronic steroids who presented with Escherichia coli urosepsis. She was initially treated with antibiotics and corticosteroids. She subsequently developed DAH due to disseminated strongyloidiasis. She was treated with oral and subcutaneous ivermectin and had complete recovery.
