Approximately, 15-20 of 40 HPVs that infect the female genital tract confer a high-risk of invasive cancer, thus HPVs account for 95% of cervix cancers. The objectives of this study were to: (i) estimate the prevalence of HPV infection in women infected with HIV in Ouagadougou, (ii) identify potential carcinogenic HPV strains and (iii) determine whether existing HPV vaccines match the isolated strains.
From May 2009 to April 2010, 250 HIV-infected women were included in this study. Each woman was screened for the presence of HPV and for HPV genotype using PCR/hybridization technique.
Of the 250 HIV-infected women, 59.6% were infected with at least one type of HPV. High-risk HPVs were identified with the following prevalence: HPV-18 (25.0%); HPV-50'S (25.5%); HPV-30'S (20.8%); HPV-16 (4.7%); HPV-45 (3.7%). Low-risk HPVs were represented by HPV-6 (5.7%) and HPV-11 (0.9%).
The issue of the study showed that the existing vaccines: Gardasil and Cervarix may be used in the country although they match only HPV-16, HPV-18, HPV-6 and HPV-11. Further investigations should be continued for the establishment of vaccine that matches all genotypes circulating in the country.
大约有 15-20 种感染女性生殖道的 HPV 可导致侵袭性癌症,因此 HPV 占宫颈癌的 95%。本研究的目的是:(i)估计感染 HIV 的女性感染 HPV 的流行率,(ii)确定潜在的致癌 HPV 株,(iii)确定现有的 HPV 疫苗是否与分离株匹配。
2009 年 5 月至 2010 年 4 月,共纳入 250 名感染 HIV 的女性。每位女性均采用 PCR/杂交技术筛查 HPV 感染情况和 HPV 基因型。
在 250 名感染 HIV 的女性中,59.6%至少感染了一种 HPV。高危 HPV 的流行率如下:HPV-18(25.0%);HPV-50'S(25.5%);HPV-30'S(20.8%);HPV-16(4.7%);HPV-45(3.7%)。低危 HPV 由 HPV-6(5.7%)和 HPV-11(0.9%)代表。
研究结果表明,现有疫苗 Gardasil 和 Cervarix 可能在该国使用,尽管它们仅与 HPV-16、HPV-18、HPV-6 和 HPV-11 匹配。应继续进行进一步的研究,以建立与该国流行的所有基因型相匹配的疫苗。
