Abstract
Opportunistic intestinal parasites are a common cause of diarrhea in HIV-infected patients. To determine the prevalence of microsporidia and other opportunistic parasites infecting HIV patients in Bogotá, Colombia, 115 patients were examined for these infections during the year 2001. The institution and the sample percent from each are as follows: Santa Clara Hospital, 33.0%; San Pedro Claver, 20.0%; Simón Bolívar Hospital, 14.8%; San José Hospital, 13.9%; Central de la Policía Hospital, 6.1%; Compensar, 5.2%; Colombian League against AIDS, 2.6%; San Ignacio Hospital, 2.6%, and the Military Hospital, 1.7%. The average patient age was 36 years, with a range from 18 to 71 years. Patients with complaint of gastrointestinal symptoms were asked to provide two consecutive stool samples. The samples were concentrated in formalin-ether and examined microscopically for intestinal coccidian parasites by direct wet slide mounts. The prevalence of intestinal opportunistic parasites was 10.4% for Cryptosporidium sp. Initially, 29% of the samples were found to be positive for microsporidian spores using a modified Ziehl Neelsen chromotrope stain, but only 3.5% of them were confirmed as positive when a calcofluor/Gram chromotrope stain was used. The general prevalence of intestinal parasites was 59.1%. The most frequently found pathogens were Blastocystis hominis, 25.2%, and Entamoeba histolytica, 13%. In other studies with HIV patients in Colombia, lower prevalences of Cryptosporidium sp. infection were observed.Downloads
