High prevalence of intermediate‐risk human papillomavirus infection in uterine cervices of kenyan women infected with human immunodeficiency virus

Abstract

The aim of this study was to investigate an association between certain human papillomavirus (HPV) types and human immunodeficiency virus (HIV) infections. Sexually active females (n = 487; 19-61 years old) were enrolled in the study. Subjects underwent Pap testing and evaluations of HIV and HPV infection status on uterine cervical cell samples. HPV genotyping was performed using a Kurabo GeneSQUARE DNA microarray test. Overall, 23 HPV genotypes were detected, and the most prevalent HPV genotype was HPV-52, followed by HPV-39, -54, -45, -56, -53, -31, -42, -16, -68, and -51. HPV-30, -53, -54, -61, and -66, which are associated with abnormal cytology, are categorized as intermediate-risk in this study. Detection of both high- and intermediate-risk HPV types was significantly associated with cervical abnormality and HIV infection. Multivariate analysis revealed that some high-risk HPV types (HPV-31, -45, -51, -56, and -59) and most intermediate-risk HPV types were associated with HIV infection, while the high-risk types (HPV-16, -18, -33, -35, -39, -52, -58, and -68) were not. The oncogenic effect of the most malignant HPV types (e.g., HPV-16 and -18) appear to be lower, while that of intermediate-risk types are greater, in areas with a high prevalence of HIV infection.
