Abstract
Among HIV-positive women, infection with multiple human papillomavirus (HPV) types is known to be more frequent and persistent, as well as a greater prevalence of high-grade genital lesions. This study aims to characterize, for the first time in Brazil, HPV presence and types among HIV-positive women of a high-risk population for genital intraepithelial neoplasia (GIN) development. A non-anonymous, voluntary, cross-sectional epidemiological survey was conducted, from June 1996 to April 1997, among 141 HIV-positive women followed at the Center of Reference in AIDS (CRAIDS). They were submitted to gynaecological examination, cytological screening and biopsies whenever necessary, for GIN and HPV DNA detection through polymerase chain reaction (PCR) technique. Positive HPV DNA were found in 80.8% patients. Two or more HPV types were detected in 45% of the samples. The most frequent HPV types detected were 16, 18 (30.5%); 61, 53 (24.4%), and non-identified types (18.7%). According to the oncogenic potential, 34.8% were considered of high-risk types. Among these HIV-positive patients, a great variety of HPV types, including high-risk types, was found in anogenital environment, as well as among young women, a great prevalence of high-grade genital lesions. Thus, it should strengthen the need for a periodical careful gynaecological examination among those women.
