Timing and necessity of endoscopy in AIDS patients with dysphagia or odynophagia.

BACKGROUND/AIMS: Dysphagia and odynophagia are common problems with significant morbidity in acquired immunodeficiency syndrome (AIDS) patients. Endoscopy in AIDS patients with esophageal symptoms is valuable for diagnosis, but the timing and necessity of routine endoscopy remains controversial.

METHODOLOGY: We retrospectively studied 40 AIDS patients undergoing upper gastrointestinal endoscopy. Among them, 25 patients were enroled with dysphagia and/or odynophagia and were put on empirical fluconazole treatment before endoscopic evaluation.

RESULTS

Fourteen (56%) of 25 patients improved after fluconazole treatment, while 11 patients had persistent symptoms. Among the 14 patients with symptomatic improvement, 7 were found to have esophageal candidiasis which improved after continuation of fluconazole for 1-2 more weeks. The other 7 patients had a normal endoscopic appearance. In contrast, among 11 patients with persistent symptoms, there were 3 patients with azole-resistant candidiasis, 3 with cytomegalovirus esophagitis, 1 with herpes simplex virus esophagitis with candidiasis, 1 with Kaposi's sarcoma, and 3 with idiopathic esophageal ulcer. They were successfully treated with Amphotericin B, Ganciclovir, Acyclovior, and oral steroids, except for the patient with Kaposi's sarcoma.

CONCLUSIONS

Routine endoscopy may not necessarily be indicated in every AIDS patient with dysphagia or odynophagia. Empirical fluconazole treatment can improve symptoms in 50% of patients. It is only indicated when patients have persistent symptoms after empirical treatment. With endoscopic examination, etiologic agents other than common candidiasis can be determined and the patients can thus be put on specific treatment.
