Prevalence of intestinal parasites in Cuban acquired immunodeficiency syndrome (AIDS) patients

Abstract

A coproparasitological study was carried out on 67 acquired immunodeficiency syndrome (AIDS) patients admitted at the Institute of Tropical Medicine 'Pedro Kouri'. The results were compared with 136 HIV-seronegative patients (control group) who were also hospitalised in the same period. In both groups monoparasitism was more prevalent than polyparasitism and intestinal protozoa were more prevalent than helminths. At least one intestinal parasite was found in 34 (51%) of the 67 AIDS patients and in 65 (48%) of the control group patients. Intestinal coccidia were only detected in AIDS patients; Cryptosporidium spp. was the most prevalent, with eight cases (11.9%), followed by Cyclospora cayetanensis with two cases (3.0%) and Isospora belli in one case (1.5%). The microsporidia Encephalitozoon (Septata) intestinalis and Enterocytozoon bieneusi were not detected. With regard to the prevalence of other pathogenic intestinal parasites in AIDS patients and the control group, no differences were found.
