AIMS: To define the relationship between morphological injury of the intestinal mucosa and infections in AIDS patients. METHODS: Forty-nine AIDS patients were examined by upper gastrointestinal (GI) endoscopy and 8 of them also by lower GI endoscopy. Biopsy specimens, taken from the lower duodenum, esophagus and rectum, were studied by light (L.M.) and transmission electron microscopy (T.E.M.). Stool examination for microorganisms was routinely performed in all patients. RESULTS: Microorganisms were detected in 37 of the 49 patients (75.5%) by combined tissue and stool examination. The histological study revealed villous atrophy, inter- and intra-enterocyte oedema and epithelial degenerative changes in most of the patients whether or not they had detectable microorganisms. CONCLUSIONS: Combined methods (endoscopy, L.M. and T.E.M., studies of tissue samples, microbiological study of stool samples) may be used to improve the documentation of infections and morphological injury of the intestinal mucosa in AIDS patients.

Abstract

AIMS: To define the relationship between morphological injury of the intestinal mucosa and infections in AIDS patients. METHODS: Forty-nine AIDS patients were examined by upper gastrointestinal (GI) endoscopy and 8 of them also by lower GI endoscopy. Biopsy specimens, taken from the lower duodenum, esophagus and rectum, were studied by light (L.M.) and transmission electron microscopy (T.E.M.). Stool examination for microorganisms was routinely performed in all patients. RESULTS: Microorganisms were detected in 37 of the 49 patients (75.5%) by combined tissue and stool examination. The histological study revealed villous atrophy, inter- and intra-enterocyte oedema and epithelial degenerative changes in most of the patients whether or not they had detectable microorganisms. CONCLUSIONS: Combined methods (endoscopy, L.M. and T.E.M., studies of tissue samples, microbiological study of stool samples) may be used to improve the documentation of infections and morphological injury of the intestinal mucosa in AIDS patients.
