Prevalence of intestinal parasitic pathogens in HIV-seropositive individuals in Northern India

Jpn J Infect Dis. 2002 Jun;55(3):83-4.


To assess the prevalence of intestinal parasitic infections in human immunodeficiency virus (HIV)-seropositive subjects, fecal samples were collected from 120 HIV-seropositive patients and were analyzed for various intestinal parasites. Thirty-six patients (30%) were found to harbor an intestinal parasite. Cryptosporidium parvum was the most common (10.8%), followed by Giardia lamblia (8.3%). Cyclospora cayetanensis and Blastocystis hominis each were detected in 3.3% of the patients, while Isospora belli and Enterocytozoon bieneusi were each detected in 2.5% of the patients. The other parasites observed were Entamoeba histolytica/E. dispar in two cases and hookworm ova in one patient. Of the 36 patients who tested positive for intestinal parasites, 27 (75%) had diarrhea. The most common parasite, which was associated with diarrhea, was C. parvum. The present study highlights the importance of testing for intestinal parasites in patients who are HIV-positive, and emphasizes the necessity of increasing awareness among clinicians regarding the occurrence of these parasites in this population.
