Background: HIV-infected women have a high prevalence of human papillomavirus (HPV) infection and are more likely to be infected with HPV genotypes that are considered high-risk and have the potential for progressing to cervical cancer. The currently available HPV vaccines protect against specific HPV genotypes that may not be the most important causes of dysplasia and potentially of cervical cancer in HIV-1-infected women. African women have been underrepresented in the studies of global prevalence of HPV genotypes. Methods: We compared the HPV genotype distribution in HIV-1-infected women from Seattle, Washington, USA and Nairobi, Kenya. The reverse line blot assay and DNA sequencing on cervicovaginal lavage (CVL) specimens were carried out. Results: The most commonly detected HPV types among the women from Seattle were HPV 56, 66, MM8, and 81; in contrast HPV 53, 33, and 58 were the most common HPV genotypes detected in the CVL specimens from the women in the Nairobi cohort. The HPV types associated with low-grade squamous intraepithelial lesions (LSIL) were HPV 53 and HPV 56. HPV types 58, 52, and 16 were associated with high-grade squamous intraepithelial lesions (HSIL). Conclusions: A better understanding of HPV genotype distribution in the most affected regions of the world is essential to planning effective vaccine strategies if we are unable to demonstrate cross-protection between HPV genotypes included in the present vaccines and those prevalent in the different populations. © 2010 International Society for Infectious Diseases.
