High Prevalence of Cervical High-Grade Lesions and High-Risk Human Papillomavirus Infections in Women Living with HIV: A Case for Prioritizing Cervical Screening in This Vulnerable Group.

INTRODUCTION

Women living with HIV (WLHIV) are at an increased risk of developing cervical precancerous lesions and cervical human papillomavirus (HPV) infection. This study aimed at evaluating the prevalence of cervical lesions and high-risk HPV (HR-HPV) infection in WLHIV in comparison to the HIV-negative women undergoing opportunistic screening. In addition, these findings among WLHIV were correlated with the clinic-demographic factors.

METHODS

A cross-sectional study was conducted among WLHIVs at a tertiary hospital and linked antiretroviral therapy (ART) center, while HIV-negative women were recruited from the health promotion clinic at our institute. With informed consent, a semi-structured questionnaire was filled on demographic and epidemiological parameters. Conventional cervical smears and samples for HPV DNA detection by HC2 high-risk HPV DNA test were collected in all participants. Cervical smears were reported using the Bethesda system 2014. Appropriate statistical analysis was performed for bivariate and multivariate logistic regression analysis for comparison between WLHIV and HIV-negative women and for correlation of abnormal cervical cytology and HR-HPV infection among WLHIVs.

RESULTS

The clinic-demographic characteristics of WLHIVs and HIV-negative women were similar. On cytology, the prevalence of cervical cytological abnormalities were significantly higher (p < 0.001) among WLHIVs (14.1%) compared to HIV-negative women (3.1%). High-grade lesions were seen in 3.7% of WLHIVs, while no high-grade lesions were detected in HIV-negative women. Cervical HR-HPV infection was also significantly higher (p < 0.001) in WLHIVs (28.9%) than HIV-negative women (9.3%). Cervical precancerous lesions in WLHIVs showed positive association with current sexually transmitted infection (STI), multiple sexual partners, tobacco use, and CD4 count less than 200/µL, while cervical HPV was positively associated with current STI, tobacco use, CD4 count less than 200/µL and negatively with ART intake. On multivariate logistic regression, cervical cytological abnormalities showed a significant association with multiple sexual partners (p < 0.001), while cervical HR-HPV infection was positively associated with current STI (p = 0.01), nadir CD4 count <200/µL (p = 0.004), abnormal cervical cytology (p = 0.002) and negatively with ART intake (p = 0.03).

CONCLUSION

Women living with HIV have a significantly higher prevalence of cervical precancerous lesions and HR-HPV infection compared to the general population. Considering the lack of an organized population-based cervical cancer screening program in many low-resource countries like ours, specific focus on screening this highly vulnerable population to reduce the morbidity and mortality due to cervical cancer is imperative.
