ABSTRACT

Background: The patients with the infection by the human of immunodeficiency virus (HIV) commonly display diarrhea. Several opportunistic infections are responsible for this picture, among them the coccidia in particular Isospora belli, are responsible for a considerable number of cases. The objective of this study was to determine the prevalence of I. belli in a group of patients with HIV who displayed diarrhea. Methods: A cross-sectional study was made. To each patient a questionnaire created for this study was applied to him and three samples were taken in consecutive days for the search of I. belli through the technique of modified Kinyoun. Results: We studied 50 patients, 48 (96%) men and 2 (4%) women. The average of age was of 35.3 (19-73) years. The I. belli was founded in 6 patients for a prevalence of 12%. The unique variable associated to the presence of I. belli was the loss of greater weight between positive patients (7 versus 2.7 kg, p = 0.03). Conclusions: The prevalence of I. belli in this group of patients was similar to the reported one in other Latin American countries. In this study the variable epidemiological who have been related to the presence of I. belli were not present and the antiretroviral therapy did not have major influences. Perhaps the presence of I. belli in this group of patients contributed of significant way to a greater loss of weight and to a greater wasting syndrome.
