Objectives: To characterize high-risk HPV types associated with cervical precancerous lesions in women living in Yaounde, Cameroon, and to determine their distribution with HIV status.

Methods: Women with abnormal pap smears recorded from February 2015 to May 2019 at Saint Martin de Porres' Health Centre, Yaounde, Cameroon, were recruited in this study after obtaining informed consent. Pap smears were collected and re-examined. Human immunodeficiency virus (HIV) serology was determined. HPV16, 18, 33, and 45 were assessed using standard PCR.

Results: All included participants (370) were HPV-positive and had either low grade squamous intraepithelial lesions (67.03%) or high grade squamous intraepithelial lesions (31.35%). They were subdivided into HIV-positive (N =102) and HIV-negative (N =268). In the HIV-negative subgroup, we observed 66.04% HPV16-positve, 41.79% HPV18-positve, 21.27% HPV33-positve and 8.21% HPV45-positve. In the HIV-positive subgroup, we observed 22.55% HPV16-positve, 5.88% HPV18-positve, 75.49% HPV33-positve, and 49.02% HPV45-positve. Married HIV-positive participants (47.14 ± 1.19) were older than both their single counterparts (34.94±1.22, P = 0.0008) and HIV-negative participants (41.43 ± 0.79, P = 0.0001). Single HIV-positive women reported higher numbers of miscarriages (P = 0.0023), and had later first sexual intercourse than HIV-negative (P = 0.0079) women.

Conclusion: Our study suggested differential expressions in high-risk HPV types with HIV status and cervical precancerous lesions and warrants more extensive studies.
