Determinants, prevalence genital hpv in men

The high prevalence of human papillomavirus (HPV), the most common sexually transmitted infection, arises from the coexistence of over 200 genetically distinct types. Accurately predicting the impact of vaccines that target multiple types requires understanding the factors that determine HPV diversity. The diversity of many pathogens is driven by type-specific or "homologous" immunity, which promotes the spread of variants to which hosts have little immunity. To test for homologous immunity and to identify mechanisms determining HPV transmission, we fitted nonlinear mechanistic models to longitudinal data on genital infections in unvaccinated men...

Background: The burden of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is disproportionately high among men, yet empirical evidence regarding the difference in prevalence of oral HPV infection between men and women is limited. Concordance of oral and genital HPV infection among men is unknown. Objective: To determine the prevalence of oral HPV infection, as well as the concordance of oral and genital HPV infection, among U.S...

BACKGROUND: Little is known about human papillomavirus (HPV) infection and genotypes when considering both anatomic site and human immunodeficiency virus (HIV) status among men who have sex with men (MSM) in low- and middle-income countries. METHODS: A cross-sectional study was conducted among MSM in Beijing, China. HIV serostatus was determined, and genital and anal HPV genotyping were performed from respective swabs. RESULTS: Of 1155 MSM, 817 (70...

Importance: The risk for skin cancer has been well characterized in white organ transplant recipients (OTRs); however, most patients on the waiting list for organ transplant in the United States are nonwhite. Little is known about cutaneous disease and skin cancer risk in this OTR population. Objective: To compare the incidence of cutaneous disease between white and nonwhite OTRs. Design, Setting, and Participants: This retrospective review of medical records included 412 OTRs treated from November 1, 2011, through April 22, 2016, at an academic referral center...

Background: Limited data are available on human papillomavirus (HPV) infection among human immunodeficiency virus (HIV)-negative or HIV-positive couples followed longitudinally. Methods: Genital HPV was assessed in 725 concordant HIV-negative couples and 209 HIV-positive couples enrolled in a male circumcision trial in Rakai, Uganda, using the Roche Linear Array assay, which detects 37 HPV genotypes. Human papillomavirus prevalence and determinants of genotype-specific concordance were assessed at annual visits...

This study determined the prevalence and risk factors for genital human papillomavirus (HPV) detection among men who deny ever engaging in penetrative sex. A questionnaire was administered to 4123 men from a cohort study of HPV natural history. Genital exfoliated cells were collected and genotyped for 36 HPV types. Eighty-eight men were classified as virgins. Log-binomial regression models identified factors associated with genital HPV detection. The prevalence of any and high-risk HPV types among 88 male virgins was 25...

Data on genotype-specific concordance of oral-oral and genital-oral HPV infections among marital couples are key to understand HPV transmission between spouses. Genotype-specific concordance of HPV infections (oral/genital) and their co-variates among 131 marital couples were determined during 6-year follow-up (FU). Seven oral scrapings were taken from both spouses, accompanied by six genital samplings from the women and one (at baseline) from the male partners. HPV-genotyping was performed by nested PCR and a Luminex®-based Multimetrix Assay...
