[Chronic abdominal pain and fever in an Ivoirian woman: Mycobacterium avium-intracellulare duodenitis in an AIDS patient in Abidjan, Cote d'Ivoire].
Duodenal infection by Mycobacterium avium-intracellulare is a common opportunistic disease in HIV-infected patients. Individuals with CD4 counts <50 cells/mm3 are at highest risk. The main symptoms are diarrhea, abdominal pain, weight loss, and fever. Endoscopic examination shows various abnormalities including disseminated nodules that may be yellowish, whitish, or pinkish in color. Other mucosal lesions may be found such as erosion, erythema, or friable edematous aspect. Since these findings are non-specific, it is important to obtain biopsy specimens for histological and microbiological examination. The most common histologic features are atrophic mucosa resembling Whipple's disease with strongly positive PAS staining. The presence of BARR in macrophages is typical of MAI. Diagnosis is based on identification of the bacteria using either conventional culture techniques or polymerase chain reaction (PCR). Differential diagnosis includes other gastrointestinal infections associated with AIDS, i.e., microsporidiosis, cryptosporidiosis, giardiosis, anguillulosis, CMV, and isoporosis. The course of the disease is usually unfavorable even with antibiotic treatment. The purpose of this report is to describe a case of duodenitis due to atypical mycobacterial infection in a 30-year-old woman who was seropositive for human immunodeficiency virus. She was hospitalized due to fever with deterioration of her general condition (more than 10% of body weight loss) and chronic abdominal pain with inflammation. Diagnosis of MAI was confirmed by biopsy and Ziehl-Neelsen coloration. The patient was treated with rifampicine, isoniazide, ethambutol, and pyrazinamide in association with stavudine, lamuvidine and efavirenz. Despite improvement of general condition, fever persisted and the patient died after 40 days of treatment.
