Abstract in Portuguese
Foram estudadas 141 mulheres HIV-positivas, provenientes do Centro de Referência em AIDS (CRAIDS) - Santos, São Paulo, Brasil. Os objetivos do estudo foram: determinar a prevalência do papiloma vírus humano (HPV) e de Neoplasia intra-epitelial genital (através dos exames de colposcopia, citologia e biópsias); descrever a prevalência do HPV e tipos através da técnica da Reação de Polimerase em Cadeia (PCR) e correlacionar as variáveis significantes epidemiologicamente com a infecção por HPV e as Neoplasias intra-epiteliais cervicais (NIC). A maioria da população analisada (87,3%) tinha até 40 anos de idade. A via de transmissão mais freqüente do HIV foi a sexual exclusiva (76,6%), sendo importante o papel do coito anal. História de uso de drogas ocorreu em 44% das mulheres; sendo cocaina a droga mais freqüente.(46,8%). Observou-se 85 colposcopias alteradas (60,3%), através das quais foram realizadas 35 biópsias dirigidas· (24,8%). Os resultados revelaram lesões de alto grau em 22,7% das biópsias de colo, 28,6% de vulva e 16,6% de vagina. Na avaliação da Biologia Molecular, o DNA do HPV esteve presente em 80,8% das pacientes, sendo detectado um único tipo de HPV em 55% dos casos e mais de um tipo de HPV em 45% das amostras positivas. Os tipos mais freqüentes foram o 16 e 18, e especificamente nas biópsias de colo, os tipos NI e 18. Segundo o potencial oncogênico, 34,8% dos tipos de HPV foram de alto risco, 54% de risco indeterminado e 13,5% de baixo risco. Houve correlação da idade menor que 30 anos com as alterações cito/histológicas, ao contrário dos baixos níveis de CD4. O uso de medicações antiretrovirais (44,7%) parece desempenhar um papel significativo no controle da progressão para neoplasia genital, independente dos níveis de CD4.

Abstract in English
We studied 141 women HIV-positive attending to the Reference Clinical Center on AIDS, Santos, São Paulo, Brazil. The aims of this study were: to determine the prevalence of Human Papillomavirus (HPV) and Genital intraepithelial neoplasia (through the exams of colposcopy, citology and biopsies); to describe the prevalence of HPV and types through the technique of Polymerase Chain Reaction (PCR) and to correlate the epidemiologically significant variables with HPV infection and Cervical intraepithelial neoplasia (CIN). The majority of individuals analysed (87.3%) were up to 40 years old. The most important way of HIV transmission was the sexual route (76.6%), in which the role of anal coitus was relevant. History of drogadiction was related by 44% of the women, with cocaine as the most frequent drug in use (46.8%). In the gynecological evaluation, it was observed 85 abnormal colposcopies (60.3%), in which we performed 35 biopsies (24.8%). In the anatomopatological results, there were high grade lesions in 22.7% of cervical biopsies, 28.6% of vulvar ones and 16.6% of vaginal ones. In the Molecular Biology evaluation, HPV DNA was present in 80.8% of the sample, and we detected one single type in 55% of all positive cases and more than one HPV type in 45% of the positive assays, totallizing 41 different types. The most frequent HPV types were 16 and 18, and on the cervical biopsies the NI and 18. According to the oncogenic potential, 34.8% of HPV DNA detected were high risk types, 54% of undetermined risk, and 13.5% of low risk. We found correlation between early age ( < 30 years old) and citolhistological abnormalities, contrasting with CD4 low levels. The use of antiretroviral medications present in 44.7% seems to play a role of the control progress to genital neoplasia, independently of CD4 levels.
