RESUMO

This study evaluated the frequency of Trichomonas vaginalis infection in human immunodeficiency virus positive (HIV+) and negative (HIV-) women in Goiania, Goiás, Brazil, comparing the presence of the parasite in the two groups and correlating it with the conditions of immunodeficiency present in these women. The diagnostic techniques used, wet mount microscopy, culture and cytology, were also evaluated, and the principal inflammatory alterations in the two groups were assessed. The HIV+ samples (test group) were collected at the Hospital of Tropical Diseases and in the Maternal and Child Healthcare Hospital, whereas the HIVnegative samples (control group) were collected at the Maternity Hospital. Swabs were used for wet mount microscopy (saline solution) and for culture (Diamonds medium), and Ayres spatula and brush were used for the cytology smears, which were fixed using a commercial fixative. A total of 237 samples were analyzed, 125 HIV-positive test samples and 112 HIV-negative controls. The overall frequency of T. vaginalis was 13.9%, 18.4% in the HIV+ and 8.9% in the HIV- group. This difference was statistically significant (p<0.05); however, the infection was not associated with immunodeficiency according to CD4, viral count and lymphocytes. There was a significant difference in the prevalence of the parasite between HIV+ and HIVpregnant women (22.6% versus 12.5%). Culture identified a frequency of T. vaginalis of 13.9%, while cytology identified a rate of 13.5% and wet mount microscopy 11.4%. Perinuclear halos were the most frequent inflammatory alteration; however, there was no difference between the groups
