High prevalence of high-risk human papillomavirus (HPV) infection among sexually active women in Ouagadougou.

Human papillomavirus (HPV) is the leading cause of cervical cancer, which in turn is the leading cause of cancer death in women in Africa. The objective of this study was to determine the prevalence of high-risk HPV infection (HR-HPV) and the distribution of genotypes encountered in the sexually active female population of Ouagadougou. In four level-two health centers, we recruited 234 women who agreed to undergo an endocervical swab. HR-HPV genotypes were identified by real-time PCR. The Chi-square test was used for comparisons, with significance defined by a P-value < 0.05. The prevalence of HR-HPV infection was 52.56%. Fourteen genotypes corresponding to 216 infections were characterized: HPV 59 (42/216), HPV 66 (30/216), HPV 56 (20/216), HPV 45 (20/216), HPV 58 (18/216), HPV 39 (18/216), HPV 51 (16/216), HPV 68 (14/216), HPV 52 (12/216), HPV 18 (12/216), HPV 35 (6/216), HPV 31 (5/216), HPV 16 (3/216), HPV 33 (0/216). HPV infection was statistically associated with age (P = 0.033) and with some specific sexual practices, such as oral sex (P = 0.001). The prevalence of HR-HPV infection among women without lesions in our study is higher than that reported previously in studies conducted in Ouagadougou among women in the general population and those found in the rest of the world. Moreover, HPV16 and 18 were not the genotypes most frequently encountered.

Oncogenic Human Papillomavirus Infection and Genotype Characterization among Women in Orodara, Western Burkina Faso.

BACKGROUND AND OBJECTIVE: Cervical cancer usually occurs several years after persistent infection with oncogenic or high-risk human papillomavirus. The objective of this study was to determine carriage of 14 genotypes of high-risk human papillomavirus among women at Orodara and then characterize the genotypes found in these women. MATERIALS AND METHODS: From June to July 2015, 120 women from the general population were recruited in the health district of Orodara. They voluntarily agreed to participate in the study. Endocervical samples were taken from these women prior to screening for precancerous lesions by visual inspection with acetic acid and lugol's iodine. Identification of high-risk human papillomavirus genotype was done using real-time PCR. RESULTS: High-risk human papillomavirus prevalence was 38.3% and the most common genotypes were HPV 52 (25.4%), HPV 33 (20.6%) and HPV 59 (11.1%). The HPV 66 was also identified with a prevalence of 9.5%. CONCLUSION: The HPV 16 and HPV 18 which are frequently associated with cancer worldwide were not found among the most frequent oncogenic HPV in women in Orodara.
