Impaired intestinal function in symptomatic HIV infection.
A longitudinal (10-22 month) evaluation of intestinal symptoms and function was performed in five children with symptomatic human immunodeficiency virus (HIV) infection. All received cotrimoxazole, ketoconazole, and immunoglobulins. A search for enteric pathogens and intestinal function tests were repeatedly performed in all patients. Mild episodes of diarrhea were observed in two children. One had cow's milk protein intolerance. Giardia lamblia was found in an asymptomatic carrier. Evidence for impaired intestinal function was found in all patients. These consisted of positive D-xylose and iron oral loads, increased steatorrhea, increased fecal excretion of alpha 1-antitrypsin, abnormal intestinal permeability, and increased food antibody levels. Our results suggest that severe diarrhea may be uncommon in children with HIV infection receiving antimicrobial prophylaxis, but that the intestinal function is frequently, and often markedly, impaired.
