Gastrointestinal strongyloidiasis in immunocompromised patients: a case report

Abstract

Strongyloides stercoralis is an intestinal nematode, endemic in tropical countries. The parasite has a complex life cycle, causing a long-lived auto infection in hosts. It may remain asymptomatic or with minor symptoms; the dormant carrier state of the illness may persist for a long period of time. Inflammatory bowel disease (IBD) including Crohn's disease (CD) and ulcerative colitis (UC), commonly treated with immunosuppressive drugs is a well-known condition predisposing individuals to various infections. The condition is more prevalent among immunocompromised patients; the diagnosis of which, however, is troublesome in such individuals. The present article reports a 45- year-old female with gastric strongyloides stercoralis infection while receiving the treatment for her underlying UC. Strongyloides stercoralis can easily be missed especially in IBD patients in the absence of accompanying diarrhea or any symptom of lower GI discomfort because it presents with various manifestations including multiple GI symptoms, multiple stool exams and special attention to peripheral eosinophilia are specially important but not so sensitive or specific.
