RESUMO
BACKGROUND: The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. METHODS: Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. RESULTS: Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. CONCLUSION: This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

Background: Persistent infection with high-risk (HR) papillomavirus (HPV) genotypes plays a central role in the pathogenesis of invasive cervical cancer. Objectives: This study aimed to determine the prevalence and distribution of HR-HPV among women with or without cervical lesions at VIA/VILI in Togo. Methods: Cervical samples were collected from 238 women with or without cervical lesions at VIA / VILI and[c3] DNA [c4]was extracted and analyzed by real-time multiplex PCR. Logistic regression analysis was used to determined risk factors associated with HPV infection.inPietro Annigoni Biomolecular Research Center (CERBA / LABIOGENE) in Burkina Faso. Results: The age of the women ranged from 17 to 61 years old, and most were married (73.5%). The prevalence of HRHPV was 35.71% and this was higher in the age range 35-39 years. The six most common genotypes were HPV 31 (18.7%), HPV 52 (13.82%), HPV 68 (13.01%), HPV 66 (9.76%), HPV 58 (8.13%) and HPV 56 (8.13%). Genotypes HPV 18 (4.07%) and HPV 16 (0.81%) were less frequent.[c5] Married or living with a partner was associated with HPV infection (OR=2,17, IC [1.20-3.91], p<0,009). Conclusion: This study allowed characterizing for the first time in Togo, HR-HPV genotypes. This will help mapping-HR-HPV genotypes circulating in West Africa.
