Enterobius vermicularis typically affects children, while Helicobacter pylori is associated with chronic gastritis and peptic ulcer disease. Reports of E. vermicularis infection in geriatric patients are exceedingly rare, and recovery of the adult worm in stool specimens is unusual. We describe an 82-year-old male on long-term corticosteroids who presented with gastrointestinal symptoms. Stool microscopy demonstrated E. vermicularis , and H. pylori infection was confirmed by rapid urease test, PCR, and histopathology. The patient responded to Albendazole and standard H. pylori eradication therapy. This case underscores a rare dual infection in an immunosuppressed elderly host.
Malhotra et al. (Wed,) studied this question.
