title: [Acute and chronic diarrhea in AIDS: study of 435 (HIV+) patients, in Buenos Aires].
abstract: OBJECTIVE
  Assessment of the rate of Diarrhoea in an infected HIV population of our medium. Assessment of its etiology, risk factors and response to treatment in both presentation of disease (Acute and chronic).
  
  
  METHODS
  This is a retrospective analysis of HIV and/or AIDS patients and diarrhea. The analytic points were: the clinical pattern of diarrhea (acute or chronic), risk factors, age, sex, etiology, stage of the disease, and response rate to treatment.
  
  
  METHODS
  Hospital Prof. A. Posadas, that is situated in the greater Buenos Aires, and that functions as a referral centre for AIDS patients.
  
  
  METHODS
  435 case records that were followed up through June 1987/ March 1994 were reviewed; 109 of the total number suffered from diarrhea.
  
  
  RESULTS
  The rate of diarrhoea in the studied population was 25% (109/435). This represented the first symptom of HIV infection in 18.3% of the patients (20/109), 49% had acute diarrhea and 51% had chronic diarrhea. An etiologic agent was established in 52.3% of the chronic diarrhoeas and in the 17.7% of the acute ones, with a 35.4% of a global isolation when basic stool test were made. Sixty three percent of the patients with chronic diarrhoea were in stage IV of HIV infection. The 78.3% of the acute diarrhoeas and 46% of the chronic ones were responsive to specific or symptomatic treatment.
  
  
  CONCLUSIONS
  HIV antibodies determinations should be included in the study protocol of diarrhea, especially in young patients. Chronic diarrhea could be related to final stages of the disease, with lower response to treatment. Endoscopy studies should be useful when the stool tests are negative, specially in the Cytomegalovirus (CMV) and Mycobacterium complex avium intracellulare (MAI) search.
