AB To determine the frequency of the parasitic pathogens in human
immunodeficiency virus (HIV)-infected patients in a developing world
setting, 295 stool specimens were examined from 166 HIV-positive
patients (49% with AIDS) at Sao Jose Hospital, Fortaleza, Brazil, from
September 1990 to March 1992. Significantly more patients with diarrhea
(85%) than without (66%) had AIDS or AIDS-related complex (ARC) (P <
.005). Of the potential parasitic causes of diarrhea, only
Cryptosporidium parvum and microsporidia were significantly associated
with diarrheal disease. Infections with C. parvum, but not
microsporidia, were associated with the rainy season (P < .005). Thus,
C. parvum and microsporidia are the most common intestinal parasites
associated with diarrhea in an HIV-infected population in Brazil and are
associated with advanced HIV disease. The association of C. parvum
infections with the rainy season suggests that contaminated water may be
important in its transmission; however, the source of human
microsporidia requires further investigation.
