Prevalence and Transmission of Beta and Gamma Human Papillomavirus in Heterosexual Couples.

ABSTRACT: Beta (?) and gamma (?) human papillomavirus (HPV) are commonly found on the skin. Few of the ? types are associated with nonmelanoma skin cancer. Little is known about transmission patterns of these HPV, specifically in the anogenital (AG) areas. The primary objective of this study was to examine the AG concordance and transmission of ? and ?HPV types between heterosexual couples.Archival samples from a previously published study examining concordance of alpha HPV types between couples were tested for ? and ?HPV. Hand, mouth, and genital samples were obtained 5 times over a 6-week period.Of the 21 couples examined, ? and ?HPV were detected in AG sites in 67% and 30% of men, respectively, and 41% and 25% of women. Positive concordance for ? and ?HPV was 27% and 20%, respectively, which was greater than the observed concordance between noncouples (10% for ?HPV and 4% for ?HPV). Transmission rate of ?HPV between AG areas was 15.9 (95% confidence interval [CI], 3.3-46.5) per 100 person months for men-to-women at risk and for ?HPV was 6.6 (95% CI, .2-36.7). Risks for women-to-men were similar.Beta and ?HPV are common in the AG area, and data suggest that they can be sexually transmitted.

Project description:The association between partner human papillomavirus (HPV) viral load and incident HPV detection in heterosexual couples is unknown.HPV genotypes were detected in 632 human immunodeficiency virus (HIV)-negative couples followed for 2 years in a male circumcision trial in Rakai, Uganda, using the Roche HPV Linear Array. This assay detects 37 genotypes and provides a semiquantitative measure of viral load based on the intensity (graded 1-4) of the genotype-specific band; a band intensity of 1 indicates a low genotype-specific HPV load, whereas an intensity of 4 indicates a high load. Using Poisson regression with generalized estimating equations, we measured the association between partner's genotype-specific viral load and detection of that genotype in the HPV-discordant partner 1 year later.Incident detection of HPV genotypes was 10.6% among men (54 of 508 genotype-specific visit intervals) and 9.0% among women (55 of 611 genotype-specific visit intervals). Use of male partners with a baseline genotype-specific band intensity of 1 as a reference yielded adjusted relative risks (aRRs) of 1.14 (95% confidence interval [CI], .58-2.27]) for incident detection of that genotype among women whose male partner had a baseline band intensity of 2, 1.75 (95% CI, .97-3.17) among those whose partner had an intensity of 3, and 2.52 (95% CI, 1.40-4.54) among those whose partner had an intensity of 4. Use of female partners with a baseline genotype-specific band intensity of 1 as a reference yielded an aRR of 2.83 (95% CI, 1.50-5.33) for incident detection of that genotype among men whose female partner had a baseline band intensity of 4. These associations were similar for high-risk and low-risk genotypes. Male circumcision also was associated with significant reductions in incident HPV detection in men (aRR, 0.53 [95% CI, .30-.95]) and women (aRR, 0.42 [95% CI, .23-.76]).In heterosexual couples, the genotype-specific HPV load in one partner is associated with the risk of new detection of that genotype in the other partner. Interventions that reduce the HPV load may reduce the incidence of HPV transmission.

Project description:BACKGROUND:Human papillomavirus (HPV) epidemiological research has generally been individual based, typically focusing on women, with couple-based research mostly consisting of cross-sectional assessment of prevalent HPV infection in both partners. OBJECTIVE:The HPV Infection and Transmission among Couples through Heterosexual activity (HITCH) study was set up to investigate the transmissibility of HPV among young, recently formed couples in Montreal, Canada. This paper provides an overview of the HITCH cohort study design and procedures as well as a narrative summary of the most important findings. METHODS:HITCH is a longitudinal investigation of HPV transmission in recently formed heterosexual partnerships initiated within 6-month pre-enrollment, a time at which considerable transmission is believed to occur. A total of 549 newly formed dyads were recruited (2005-2011) from postsecondary institutions, including 502 young women and their male partners. An additional 46 males were enrolled at follow-up, as some women enrolled a subsequent partner at follow-up. Women aged 18-24 years were followed for 24 months for acquisition of HPV types not present at enrollment, whereas men returned for a single follow-up visit at month 4, for a sum total of 3361 clinic visits. The last follow-up visit occurred in January 2014. Extensive sociodemographic, sexual behavioral, and medical history data were collected every 2-4 months using computer-assisted, self-administered questionnaires. Furthermore, participants provided genital, blood, oral, and hand specimens for HPV assessment. RESULTS:Although in its early analysis stage, HITCH has produced important publications. Findings from HITCH have increased the available knowledge about the natural history of HPV transmission and its determinants, provided further evidence regarding oral-oral and oral-genital routes of HPV transmission, and supplied empirically valid epidemiological parameters of HPV transmission to assist mathematical modelers in health economic assessments. In addition, HITCH data were made available to several multistudy collaborations evaluating new HPV detection assays and evidence for-or-against HPV type replacement following the introduction of HPV vaccination. CONCLUSIONS:HITCH will continue to offer a unique resource for research on HPV transmission. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID):RR1-10.2196/11284.
