PURPOSE: to evaluate CD4+ T lymphocyte cell count and HIV viral load influence on the presence of cervical squamous intraepithelial lesions (SIL). METHODS: cross-sectional study of 134 HIV-infected women submitted to uterine cervical biopsy, HIV viral load quantification and CD4+ T lymphocyte cell count. Viral load and CD4+ T lymphocyte cell count were performed before biopsy timing. Three different levels of viral load (<400 copies/mL; 401 to 50,000 copies/mL; >50,000 copies/mL) and CD4+ T lymphocyte count (<200 cells/mm³; 200 to 350 cells/mm³; >350 cells/mm³) were defined. Data were statistically analyzed by the chi2 test, linear tendency chi2 test, Mantel-Haenszel test, and analysis of variance, with level of significance set at p<0.05 and 95% confidence interval. RESULTS: there was no risk tendency for HIV-infected women to show SIL with viral load level increase or CD4+ T lymphocyte reduction. Comparing viral load with the presence or absence of SIL, stratified by quantification timing, there was a significant difference for values over 400 copies/mL (p=0.048; OR: 3.17; 95% CI: 1,02-9.93). No association was found between CD4+ T lymphocyte cell count and SIL. CONCLUSION: patients with HIV viral load higher than 400 copies/mL, performed before uterine cervical biopsy, showed a 3.17 times greater chance to develop SIL. CD4+ T lymphocyte count had no influence on the development of SIL.

PURPOSE: to evaluate the prevalence of vulval squamous intraepithelial lesions and associated factors in HIV-infected patients attended at the public health services of Rio de Janeiro city. METHOD: a total of 374 HIV-infected patients were attended at public services in Rio de Janeiro city and submitted to gynecological examination, Pap smear and colposcopic examination of the cervix and vulva. The association of vulval intraepithelial lesion was analyzed according to the results of clinical (age and cervical lesions), laboratorial (CD4 count) and behavioral (number of partners and smoking habit) variables. The study (independent) variables were the epidemiological data, the immunologic status and the results of gynecological propaedeutic. Thus, age, the smoking habit, number of sexual partners, count of T CD4 lymphocites, and cervical intraepithelial lesion were selected. In the beginning, a bivariate analysis was performed, aiming at assessing the association between the presence of vulval intraepithelial lesion (ultimate variable) and the independent variables (age, smoking habits, number of sexual partners, cytology, colposcopy and CD4 count). Thereafter, the results with statistical significance (p<0.05) were submitted to a multiple logistic regression, and the probability ratio with the respective 95% confidence interval was established. RESULTS: the prevalence of vulval intraepithelial lesions was 40%. In the multivariate analysis CD4 count below 500 cells/mm³ OR=2.69 [IC 95%: 1.61-4.52], abnormal colposcopy OR=1.64 [IC 95%: 1.01-2.67] and age under 26 OR=1.98 [IC 95%: 1.18-3.30] were significant. In the vulval and cervical simultaneous lesion subgroup, age under 26 OR=3.30 [IC 95%: 1.65-6.59] and CD4 count below 500 cells/mm³ OR=4.15 [IC 95%: 1.92-8.96], were significant on analysis. CONCLUSIONS: the prevalence of vulval squamous intraepithelial lesions in HIV-infected patients is high. Immunodeficiency, presence of cervical intraepithelial lesions and age under 26 were associated with the presence of vulval intraepithelial lesions.
