Actinomyces infection of a cytomegalovirus esophageal ulcer in two patients with acquired immunodeficiency syndrome.

Abstract

Esophageal disease is a significant cause of morbidity among patients with the acquired immunodeficiency syndrome (AIDS). Many organisms have been implicated in the pathogenesis of dysphagia and odynophagia. We describe a unique presentation of actinomyces esophageal infection in two homosexual male patients with AIDS and biopsy proven CMV esophagitis. After failure of esophagitis to resolve with ganciclovir or foscarnet therapy, the patients underwent repeat endoscopy and were subsequently found to have a secondary infection of the ulcers by Actinomyces. Treatment with intravenous penicillin G resulted in symptomatic and histopathological resolution of esophageal disease. This appears to be the first report of Actinomyces infection of esophageal ulcers in AIDS patients, possibly a commonly overlooked diagnosis.
