Gongalves, A.P.M. Fernandes, A. Ribeiro-Silva, S.M. Quintana, G. Duarte, E.A. Donadi. University of Sdo Paulo, Sio Paulo, Brazil Background: HIV+ women are more susceptible to present lower genital tract neoplasia, especially cervical tumors. The higher incidence of squamous intraepithelial lesions (SIL) has been correlated with the progression of immunosuppression. Up to now, few studies have been reported in HIV+ patients evaluating the qualitative and quantitative analysis of infiltrating immune cells in SIL biopsies. Methods: To analyse the local immunological profile according to the severity of SIL we evaluated cervical specimens collected from 32 HIV+ and 42 HIV- control patients presenting with low- or high-grade SIL. The number of Langerhans cells (LC) (S100+ cells) and of cells bearing surface HLA DR and HLA DQ molecules was evaluated by immunohistochemical procedures. Results: Preliminary data showed that biopsies from HIV+ group presented fewer LC when compared to the HIV- group. HIV+ women with low-grade SIL exhibited 4 times more LC compared with high-grade SIL. In contrast, the ratio of LC in low and high-grade SIL was 1.63 in HIV- patients. Among HIV+ patients, a focal stromal distribution of HLA DR+ cells was observed near high-SIL area, whereas a diffuse distribution was observed in low-grade SIL. No significant differences were found with respect to HLA DQ+ cells in low/high SIL groups. Conclusions: As HIV+ patients are frequently under exposition to human papillomavirus (HPV) infections and CD4 variations, local impaired control of the immune response facilitates the increased prevalence of SIL. The evaluation of additional markers in these series of patients are still in progress in our lab. These results may help the understanding of the immunological mechanisms underlying the development of SIL.

Prior cervical HPV disease may indicate increased risk for vaginal or vulvar intraepithelial neoplasia (VAIN or VIN) in HIV+ women with hysterectomy. Methods: Data on cervical and post-hysterectomy vaginal Pap smears, colposcopy and biopsies from semiannual visits (1993-2000) were analyzed for 26 HIV+ U.S. women who participated in the HIV Epidemiology Research study and had a hysterectomy during the study. Results: 17 of 26 women (65%) had cytologic or histologic evidence of cervical dysplasia at or before hysterectomy. After hysterectomy, SIL was noted on a subsequent vaginal smear for 11/17 (65%) women with prior cervical dysplasia (median follow-up 34 m) and 1/9 (11%) women without prior cervical dysplasia (median follow-up 37 m) (OR=1 5, p=.01). Risk of SIL on vaginal smear was higher in women with HPV or low CD4 count at time of hysterectomy (6/6 with CD4<200 cells/VL had SIL during follow-up) but was not significantly related to age or the time from first detection of cervical SIL to hysterectomy (p=0.07, 0.13, respectively). Vaginal and vulvar biopsies from 7 women with prior cervical dysplasia showed: normal finding in 1, VAIN I in 2, VAIN II in 1, and VAIN III in 3. Biopsies from 2 women without prior cervical dysplasia showed: VAIN I and VAIN I plus VIN I. Conclusions: The high rates of vaginal SIL and VAIN Il/111 after hysterectomy in HIV+ women with prior cervical dysplasia suggest regional HPV disease in these women. Lower genital tract monitoring may be warranted for HIV+ women with documented cervical HPV disease.

Arbel1, M. Hauzi, H. Nagusa2, E. Rubinstein', R. Kochman-Haimov1, V. Eisenberg1, T. Goslitzer', S. Maayan1. 1Hospital, Hadassah Hospital AIDS Center, Jerusalem, Israel; 2Institution, Jerusalem, Israel Background: Seventy seven of the 87 (88.5%) HIV+ women currently followed in Jerusalem are recent Ethiopian immigrants. As a whole, this group faces extreme stress due to the immigration process itself and the social stigma associated with being HIV+. The group includes many discordant couples and single mothers. Consequently, these women tend to assign a low priority to their own health in general and to invasive gynecological procedures in particular. Since cervical carcinoma is the most prevalent gynecological cancer in subSaharan Africa, we attempted to proactively (i.e: staff initiated) offer routine pap smears to all HIV+ immigrant women. Methods: Immigrant sero+ women were repeatedly counseled by an Ethiopian female member of the staff, in a cultural and gender sensitive manner, regarding the importance of pap smears. Results: 29 of the 77 HIV+ women (38%) visited the OBGYN-HIV clinic over a one year period. Of these, 6 (21%) were found to have cervical intraepithelial neoplasia (cin); 4 (14%) had high grade squamous intra- epithelial lesions (HGSIL) and 2 (7%) had low grade SIL. Three of 6 HIV+ women with cervical pathology underwent hysterectomy/conization. No cervical pathology was observed among 10 HIV seronegative Ethiopian women sampled at a regional OBGYN clinic. Lower CD4 counts were noted among HIV + women with CIN (232 cells +1.57) than among HIV+ women with normal cervix (327 cells +5.9, p=ns). Conclusions: 1.High rate of CIN with high proportion of HGSIL was detected in an incidental cohort of HIV + immigrant Ethiopian women. 2.The lower mean CD4 in the HIV+/CIN+ than in the HIV+/CIN- may suggest a trend which needs corroboration in a larger cohort. 3.Culture-and gender-sensitive proactive routines towards pap smears are required in this unique population to facilitate the detection of the frequent and serious CIN cervical pathology.

Roughly 82% (244) women underwent colposcopy, with a final prevalence of 25.6% for HPV/NIC I and 11.6% for NIC II/Ill; 2 (1.1%) cases of high-grade vaginal intraepithelial neoplasia (VAIN II/Ill); and 8 (5.3%) cases of high-grade vulvar intraepithelial neoplasia (VAIN 11/111). High-risk HPV DNA was detected in 93.8% of those diagnosed with NIC II/IIIN/VAIN III, in 63.6% of the NIC I and in 32.5% of the colposcopically negative patients Conclusions: Human papillomavirus-associated disease was highly prevalent in this cohort, and was more likely to be multicentric and involves the vulva, vagina, and cervix. Detection of high-grade VIN in 8 and high-grade VAIN in 2 of these HIV+ women suggests they may also be at risk for developing invasive vulvar and vaginal carcinoma. The high prevalence of high-risk oncogenic HPV in women with negative colposcopic diagnosis points out to a potential risk of developing genital HPV-related neoplasia even in those women without detectable lesions and emphasizes the need of a comprehensive care approach in the routine management of HIV+ women Presenting author: Fabio Russomano, Av das Americas 3555 bl 2 sala 302 Rio de Janeiro Brazil 22631-003, Brazil, Tel.: +55+21+25644933, Fax: +55+21+25644933, E-mail: fabiorussomano@ montreal.com.br ThPeC7550 Tuberculosis and AIDS in Espirito Santo State, Brazil S.F.
