Abstract
In order to verify the occurrence of intestinal parasitic infections in human immunodeficiency virus (HIV) /acquired immunodeficiency syndrome (AIDS) patients, 100 HIV/AIDS patients (Group 1) and 85 clinically healthy individuals (Group 2) were submitted to coproparasitological examination. Intestinal parasites were detected in 27% of patients from Group 1 and in 17.6% from Group 2. In Group 1 the most frequent parasites were Strongyloides stercoralis (12%), with 2 cases of hyperinfection; Isospora belli, 7%; Cryptosporidium sp., 4%; with 1 asymptomatic case and hookworm, 4%. Of the infected patients from Group 1 who reported to be chronic alcoholics, 64.3% had strongyloidiasis. Only 6 of the 27 infected patients from Group 1 were on highly antiretroviral therapy (HAART). In Group 2 the most frequent parasites were S. stercoralis, 7.1%; hookworm, 7.1% and Giardia lamblia, 3.5%. In conclusion, diagnosing intestinal parasites in HIV/AIDS patients is necessary especially in those who report to be chronic alcoholics or are not on antiretroviral treatment.
