[Acute diarrhea in adults in a Parisian district. Clinical, bacteriologic endoscopic and histologic aspects. Study of 52 cases]. / La diarrhée aiguë de l'adulte en région parisienne. Aspects cliniques, bactériologiques, endoscopiques et histologiques. Etude de 52 cas.

ABSTRACT

From 1985 through 1988, 52 patients aged 16 to 85 years and referred for acute diarrhea underwent routine clinical, microbiological, endoscopic and histopathological examinations. Enteropathogens were isolated in 50 percent of patients, mostly from stool samples rather than from biopsy samples, though results were sometimes dissociated. Significantly lower digestive endoscopic abnormalities were seen in 60 percent of patients. Upper gastrointestinal endoscopy was not contributive. Rectal and colonic biopsies showed histological abnormalities in nearly all cases half of which were polymorphonuclear infiltrates and crypt abscesses. Glandular distortion was not found. An analysis of clinical, endoscopic and histological data showed that major abnormalities were mostly, but not constantly, related to infections due to enteroinvasive bacteria. As in other studies, a high rate of negative stool cultures was observed. Based on these results, we suggest to perform either further and more sophisticated microbiological investigations, or to conduct a routine search for viral infections whose incidence, among adult patients with acute diarrhea, is actually unknown.
