Genotypic distribution of human oncogenic papillomaviruses in sexually active women in Burkina Faso: Central, Central-Eastern and Hauts-Bassins regions

this study was conducted to determine the distribution of high-risk human papillomavirus (HR-HPV) genotypes in women in the general population of three regions of Burkina Faso

Oncogenic human papillomavirus infection and genotypes characterization among sexually active women in Tenkodogo at Burkina Faso, West Africa

Objective: This study was conducted to determine the prevalence and distribution of high-risk human papillomavirus (HR-HPV) genotypes among sexually active women in Tenkodogo, Burkina Faso. Methods: Among 131 sexually active women attending the Tenkodogo Urban Medical Center, endocervical samples were collected prior to screening for precancerous lesions. After viral DNA extraction, fourteen HR-HPV genotypes were characterized by real-time multiplex PCR in these cervical samples. Results: The mean age was 35.5 ± 9.5 years. Of the 131 women, 45 were infected with at least one HR-HPV genotype. The prevalence of HR-HPV infection among these women was 34.4%. Among the 45 oncogenic HPV-infected women, single HR-HPV genotype was found in 55.6% while 44.4% were infected with more than one HR-HPV genotype. The most frequent genotypes were HPV56 (36.5%), HPV66 (36.5%). Conclusion: Tenkodogo women included in this study had a higher prevalence of HPV 56, HPV 66. A larger study with a more representative sample would therefore be needed to determine predominant oncogenic genotypes in the subregion and especially in cancer cases.

Molecular Epidemiology of High-Risk Human Papillomavirus Infection in Burkina Faso

The aim of the present study was to determine the distribution of high-risk human papillomavirus (HR-HPV) genotypes in childbearing age women, teenage girls, HIV-infected women, women with high-grade precancerous lesions and cervical cancer, sex workers, men, and otolaryngology tumor cases in Burkina Faso. This descriptive cross-sectional study with several target groups, consisted of 2386 samples from Burkina Faso. HR-HPV genotypes were characterized using real-time multiplex PCR. The prevalence of HR-HPV ranged from 15.63 to 72.31% depending on the target population and the nature of the samples. The most predominant genotypes in descending order were HPV-56, HPV-52, HPV-39, HPV-59, HPV-51, HPV-35, HPV-31, HPV-18, HPV-68, HPV-16, HPV-66, HPV-58, HPV-45, and HPV-33. The results of the present study show a wide variation in the distribution of HR-HPV genotypes in Burkina Faso. Genotypes 16 and 18 covered by HPV vaccines only accounted for 32.23% of HR-HPV cases
