Cervical cytological abnormalities and human papilloma virus infection in women infected with HIV in Southern India.

Aim: The aim of this study was to examine the association between CD4 count, human papilloma virus (HPV) infection, and the risk of cervical intraepithelial neoplasia among HIV-infected women.

Methods: A cross-sectional study was conducted among 104 HIV-infected women attending an antiretroviral therapy clinic. They underwent Pap smear and cervical HPV DNA testing.

Results: The overall prevalence of HPV infection was 57.7%. HPV 16 was the commonest genotype found (38.5%); HPV 16 and 18 put together contributed to 73.3% of HPV infection; 27.5% of HIV-infected women had squamous cell abnormalities. Cervical intraepithelial neoplasia was less likely among women with CD4 count > 500/mm (12%) and in those without opportunistic infections (17.8%). The prevalence of high-risk HPV infection was higher in women with high-grade squamous intraepithelial lesions or greater lesions (85.7%) as compared to women with normal cytology (52.1%).

Conclusion: The high prevalence of HPV infection and cervical intraepithelial neoplasia in HIV-infected women warrants the need for regular Pap smear screening in these women and routine HPV vaccination for adolescents to reduce the burden of cervical cancer in India.
