Background: Human papillomavirus (HPV) infection is the principal cause of invasive cervical cancer. There is some evidence that male circumcision (MC) may protect against HPV infection and related disease in both men and women. The purpose of this study was to conduct a systematic review of the literature to assess the association between MC and genital HPV infection indicators including genital warts. Methods: A systematic search of Medline was conducted to identify all relevant studies from February 1971 to August 2010. Effect estimates were included in random effects models. Results: A total of 21 studies with 8046 circumcised and 6336 uncircumcised men were included in the meta-analysis. MC was associated with a statistically significant reduced odds of genital HPV prevalence (odds ratio = 0.57, 95% confidence interval: 0.42-0.77). This association was also observed for genital high-risk HPV prevalence in 2 randomized controlled trials (odds ratio = 0.67, 95% confidence interval: 0.54-0.82). No associations were found between MC and genital HPV acquisition of new infections, genital HPV clearance, or genital warts. Conclusions: This meta-analysis shows a robust inverse association between MC and genital HPV prevalence in men. However, more studies are needed to adequately assess the effect of MC on the acquisition and clearance of HPV infections. MC could be considered as an additional one-time preventative intervention likely to reduce the burden of HPV-related diseases both in men and women, particularly among those countries in which HPV vaccination programs and cervical screening are not available. © 2012 American Sexually Transmitted Diseases Association All rights reserved.

Infectious Agents and Cancer | Year: 2011

Background: Certain Human Papillomaviruses (HPVs) are the infectious agents involved in cervical cancer development. Detection of HPVs DNA is part of the cervical cancer screening protocols and HPVs genotyping has been proposed for its inclusion in these preventive programs. The aim of this study was to evaluate three novel genotyping tests, namely Qiagen LQ, RH and PS, in clinical samples with and without abnormalities. For this, 305 cervical samples were processed and the results of the evaluated techniques were compared with those obtained in the HPVs diagnostic process in our lab, by using HC2 and Linear Array (LA) technologies. Results: The concordances and kappa statistics (k) for each technique compared with HC2 were 98.69% (k = 0.94) for LQ, 98.03% (k = 0.91) for RH and 91.80% (k = 0.82) for PS. There was a very good agreement in HPVs type-specific concordance for the most prevalent types HPV16 (kappa range = 0.83-0.90), HPV18 (k.r.= 0.74-0.80) and HPV45 (k.r.= 0.82-0.90). Conclusions: The three tests showed an overall good concordance for HPVs detection when compared with HR-HC2 system. LQ and RH rendered lower detection rate for multiple infections than LA genotyping. However, our understanding of the clinical significance of multiple HPVs infections is still incomplete and therefore the relevance of the lower ability to detect multiple infections needs to be evaluated. © 2011 Godínez et al; licensee BioMed Central Ltd.
