[Endoscopic evaluation of chronic human immunodeficiency virus-related diarrhea].
Chronic diarrhea is an important clinical problem in patients infected with HIV. Data assessing the diagnostic yield of upper and lower endoscopy are limited. We reported 10 cases of HIV-infected patient referred to our hospital for chronic diarrhea from March 1995 to June 1999. 60% of the pathogens were identified obviously by stool studies. Cryptosporidium and Mycobacterium avium intracellulare (MAI) were the most common organisms. In this study, endoscopy identified 2 additional cases of MAI and one of 5 cryptosporidia detected in stool. Immunologic test identified a CMV infection in one case. Stool tests and endoscopy identified obviously 80% of the pathogens. Most investigators and us agree that stool studies should be the first diagnostic test. In patients with negative stool studies, lower endoscopy is more cost-effective than upper endoscopy and indicated as an initial exam.
