Prevalence of cervical high-risk human papillomavirus among Zimbabwean women living with HIV

Abstract

Background: Women living with HIV (WLWH) are six times more likely to develop cervical cancer (CC). There is also an increased incidence of CC in women with optimal HIV disease control, despite immune reconstitution due to antiretroviral therapy (ART).

Objectives: This study describes the prevalence and age-specific genotype distribution of hrHPV among an urban cohort of WLWH. Additionally, we report the HIV disease profile and age-specific outcomes of hrHPV DNA screening in WLWH attending routine CC screening at Newlands Clinic, Harare, between January and December 2021.

Method: This was a descriptive cross-sectional design based on a retrospective review of records of WLWH who were screened for hrHPV infection. We assessed the prevalence of hrHPV infection during the study period.

Results: We included data for 2745 women who had an hrHPV DNA test. The median age at the time of testing was 45 years (interquartile range [IQR]; 37–52) The median duration on HIV ART was 10.2 years (IQR: 6.2–13.3). The proportion of women with undetectable viral loads (< 50 copies/mL) was 91.2%. The prevalence of hrHPV infection was 53%. The most prevalent genotypes were human papillomavirus (HPV) 58 (11%), HPV 52 (10%), HPV 35 (10%), and HPV 16 (9%).

Conclusion: Our study reports a high prevalence of HPV and hrHPV including other subtypes than 16 and 18. These results highlight the continued importance of CC screening and prophylactic HPV vaccinations among WLWH.
