Persistent high-risk human papillomavirus (HR-HPV) infection causes cervical cancer, the third leading cause of cancer mortality in women worldwide. High rates of HR-HPV and cervical cancer occur in sub-Saharan Africa and are exacerbated by the HIV epidemic, making prevention of HR-HPV and HIV priorities. Male circumcision reduces HIV acquisition in men. As presented in this article, randomized controlled trial data also demonstrate that male circumcision reduces penile HR-HPV infection in both HIV-negative and -positive men. Male circumcision of HIV-negative men also reduces the prevalence and incidence of HR-HPV infections in their female partners. However, male circumcision of HIV-positive men has no effect on HR-HPV infection in their female partners. These data demonstrate that male circumcision is most effective prior to sexual debut, and the presence of the male foreskin facilitates HIV and HR-HPV infection in men and their female partners. Additional studies that utilize the foreskin mucosa obtained at the time of male circumcision are needed to assess the mucosal microenvironment in HIV and HR-HPV coinfections to develop additional preventive and therapeutic approaches.
持续存在的高危型人乳头瘤病毒(HR-HPV)感染可导致宫颈癌,这是全世界女性癌症死亡的第三大主要原因。撒哈拉以南非洲地区的 HR-HPV 和宫颈癌发病率较高,且 HIV 流行情况更为严重,因此预防 HR-HPV 和 HIV 感染至关重要。男性包皮环切术可降低男性感染 HIV 的风险。本文介绍的随机对照试验数据还表明,男性包皮环切术可降低 HIV 阴性和阳性男性的阴茎 HR-HPV 感染率。对 HIV 阴性男性进行包皮环切术还可降低其女性性伴侣中 HR-HPV 感染的发生率和患病率。但是,对 HIV 阳性男性进行包皮环切术对其女性性伴侣的 HR-HPV 感染没有影响。这些数据表明,男性包皮环切术在首次性行为之前最有效,而男性包皮的存在可促进 HIV 和 HR-HPV 感染男性及其女性性伴侣的感染。需要开展更多研究,利用男性包皮环切术时获得的包皮黏膜来评估 HIV 和 HR-HPV 合并感染中的黏膜微环境,从而开发其他预防和治疗方法。
