BACKGROUND: [corrected] Gastrointestinal tract disorders are frequent among human immunodeficiency virus infected children, with important repercussions on nutrition and survival. Most studies related to this subject were restricted to adults, being less investigated the problem in the children.
AIMS: To study intestinal digestion, absorption, microbiological and morphological findings among human immunodeficiency virus infected children.
MATERIAL AND METHODS: Eleven human immunodeficiency virus infected children under 13 years old, belonging to clinical categories A, B or C, separated in two groups: five patients with current or recent episode of diarrhea and six patients without diarrhea in the last 30 days preceding entering in study. Investigation proposed: microbiological and morphological analysis of small intestine and rectum biopsy; stool exams for bacterium, parasite, rotavirus, Mycobacterium species and Cryptosporidium; D-xylose test
RESULTS: All tested subjects (9/11) had low D-xylose absorption (8,4 _ 24,4 mg d/L). Small intestinal mucosa histology findings were nonspecific, represented, in majority, of grade I/II enteropathy (6/10). Increased cellular infiltration of the chorion was observed in all specimens. Rectum histology alterations were also nonspecific, with chorion increased cellular infiltration. Mycobacterim avium intracellulare and Cryptosporidium were the solely microorganisms founded, both in stool
CONCLUSIONS: Our study demonstrated high prevalence (100%) of intestinal malabsorption among human immunodeficiency virus infected children, despite the occurrence or not of diarrhea. It was not possible to establish relationships between the presence of microorganisms, intestinal malabsorption, intestinal morphologic findings and the occurrence or not of diarrhea. There was no correlation between D-xylose and intensity of villous atrophy.
