Abstract

Introduction: Although anal cancer is more common in women, most of the studies on the role of high-risk human papillomavirus (hrHPV) infection in anal squamous lesions have focused on high-risk male patients. Therefore, we compared the genotype profile and clinicopathologic correlation of hrHPV infection in human immunodeficiency virus-positive (HIV+) men and women. Materials and methods: We retrospectively analyzed 2254 HIV+ patients (1931 men and 323 women) who had undergone anal Papanicolaou tests at our institution; 1189 of them also had follow-up biopsy data available. HPV genotyping was performed using the Roche Cobas system and correlated with the cytologic and histologic diagnosis. Results: Compared with the HIV+ men, the HIV+ women had a significantly lower rate of hrHPV infection (67.5% versus 78.5%; P < 0.0001) but a significantly higher rate of high-grade squamous intraepithelial lesions (HSILs) on anal Papanicolaou tests (4.6% versus 2.5%; P < 0.05). Other high-risk HPV (ohrHPV), as a group, is much more common than HPV16 or HPV18 in both genders. HIV+ women had significantly lower HPV16 and ohrHPV infection rates than did HIV+ men. However, the HPV18 infection rates were similar between HIV+ women and HIV+ men. For both genders, the rates of HSILs or high-grade anal intraepithelial neoplasia (AIN2-3) were significantly increased when coinfection of ohrHPV with either HPV16 or HPV18 was present. Conclusions: Although both HIV+ men and HIV+ women have an increased risk of hrHPV infection, HIV+ women have different hrHPV genotype profiles and higher rates of high-grade lesions. Coinfection with different genotypes of hrHPV can significantly increase the risk of HSILs or AIN2-3 in both genders and could requires vigilant clinical and laboratory follow-up.
