[Prevalence of cryptosporidiosis in diarrheic syndrome in HIV positive patients].
During the period February 1987-June 1988, we examined 542 stool samples of 271 HIV positive patients both with and without full-blown AIDS. One hundred patients with either acute or chronic diarrhea and 180 patients without diarrhea were studied. The stool samples were examined for the presence of Cryptosporidium sp., other protozoa, helmints, and pathogenic enterobacteria. We found a prevalence of 14.3% of Cryptosporidium sp. in patients with full-blown disease and diarrhea. We encountered no Cryptosporidium sp. among asymptomatic patients. The occurrence of diarrhea was significantly associated with a CD4/CD8 ratio lower than 0.4, with the finding of Cryptosporidium sp. in the stools, being a CDC group IV, and with a positive stool culture for pathogenic enterobacteria. The diarrhea caused by Cryptosporidium sp. could not be distinguished, on clinical grounds, from diarrhea caused by other etiologic agents.
