Objective 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. Method This multicenter, descriptive cross-sectional study involved 1321 sexually active women in five cities in three regions of Burkina Faso: Central, Central-Eastern and Hauts-Bassins regions. After collection of endocervical specimens, pre-cervical lesions were screened by visual inspection with acetic acid and lugol (VIA / VILI). HR-HPV genotypes were characterized by multiplex real-time PCR after extraction of viral DNA. Results The mean age of women was 31.98 ± 10.09 years. The HR-HPV infection in the three regions ranged from 26.16% to 43.26% with 35.42% as overall prevalence in women. The most common HR-HPV genotypes in descending order were: HPV 56, 52, 66, 59, 39, 51, 18, 35. The prevalence of bivalent vaccine genotypes (HPV16 / 18) was 7.83% against 63.78% of genotypes not covered by HPV vaccine; 36.32% (170/468) of women had multiple concomitant HR-HPV infections. Conclusion this study showed significant regional variation and high prevalence of HR-HPV infection in women. The predominant genotypes differ from those covered by available vaccines in Burkina Faso. These results will help guide our health policies towards better prevention of cervical cancer. The diversity of oncogenic genotypes is sparking a large-scale study in the West African sub-region, particularly in cases of cancer and the introduction of the nonavalent vaccine which includes HPV 52 found among the predominant genotypes in this study.
目的 本研究旨在确定布基纳法索三个地区一般人群中女性高危型人乳头瘤病毒(HR-HPV)基因型的分布情况。方法 这项多中心描述性横断面研究涉及布基纳法索三个地区(中部、中东部和上盆地地区)五个城市的1321名性活跃女性。收集宫颈内样本后,通过醋酸和卢戈氏碘液目视检查(VIA/VILI)筛查宫颈前病变。提取病毒DNA后,通过多重实时PCR对HR-HPV基因型进行鉴定。结果 女性的平均年龄为31.98±10.09岁。三个地区的HR-HPV感染率在26.16%至43.26%之间,女性总体感染率为35.42%。按降序排列,最常见的HR-HPV基因型为:HPV 56、52、66、59、39、51、18、35。二价疫苗基因型(HPV16/18)的感染率为7.83%,而未被HPV疫苗覆盖的基因型感染率为63.78%;36.32%(170/468)的女性同时感染了多种HR-HPV。结论 本研究显示女性中HR-HPV感染存在显著的地区差异且感染率较高。主要基因型与布基纳法索现有疫苗所覆盖的基因型不同。这些结果将有助于指导我们制定更好地预防宫颈癌的卫生政策。致癌基因型的多样性正在引发西非次区域的大规模研究,特别是在癌症病例以及引入包含本研究中主要基因型之一HPV 52的九价疫苗方面。
