Strongyloides stercoralis infection presenting as an unusual cause of massive upper gastrointestinal bleeding in an immunosuppressed patient: a case report

Abstract

Summary

Strongyloidiasis caused by Strongyloides stercoralis is a rare but well documented cause of massive upper gastrointestinal (GI) bleeding especially in endemic areas. However, oesophagogastroduodenoscopic findings and extractions of S. stercoralis, in the adult worm form, from the duodenum is even rarer. We report a case of a 27-year-old Tanzanian woman with HIV who presented with massive upper GI bleeding. She had S. stercoralis, in the adult worm form, traversing the stomach and duodenum and extracted by oesophagogastroduodenoscopy (OGD). She was treated successfully with Ivermectine and antiretroviral therapy for HIV was initiated. Strongyloidiasis should be included in the differential diagnosis of mass upper GI bleeding in immunosuppressive patients living in, or originating from, endemic areas. We believe this to be the first case to be reported from our environment.
