Gay, bisexual, and other men who have sex with men (MSM) and transgender women, particularly those who are living with HIV, are disproportionately affected by human papillomavirus (HPV). For this ...narrative review of HPV health outcomes and vaccination for gay, bisexual, and other MSM and transgender women in the United States, we highlighted 71 publications regarding 1) burden of HPV infections and related diseases; 2) HPV vaccine efficacy; 3) HPV vaccination recommendations; 4) HPV vaccination coverage; 5) real-world vaccine effectiveness and health impacts; and 6) HPV vaccination acceptability. Vaccination is effective at reducing HPV infections among MSM; in the United States, routine HPV vaccination is recommended for all adolescents at age 11-12 years and for all persons through age 26 years. Efforts are ongoing to increase vaccination coverage and monitor health impacts of vaccination. Increasing vaccination coverage before sexual exposure to HPV is expected to reduce the burden of HPV-related disease.
Trichomonas vaginalis is one of the most common human parasitic infections in the United States, as well as the most prevalent non-viral sexually transmitted infection. However, it has long received ...much less consideration than other parasitic and sexually transmitted diseases. Much of this inattention can be attributed to a poor understanding of the public health impact of trichomoniasis. Increasing recognition of the sequelae of infection, including increased risk of infection with human immunodeficiency virus and adverse outcomes of pregnancy, has led to increased interest in T. vaginalis. Recent innovations include development of diagnostic tests that could improve detection of the parasite. A number of important questions, such as the epidemiology among men and women, the true public health burden of symptomatic and asymptomatic T. vaginalis infections, and whether current treatments will be adequate to reduce the substantial health disparities and costs associated with trichomoniasis, need consideration to remedy neglect of this important disease.
Abstract
Background
Juvenile-onset recurrent respiratory papillomatosis (JORRP) is a rare and serious disease caused by human papillomavirus (HPV) presumably acquired during vaginal delivery. HPV ...vaccination of females through age 26 years, recommended in the United States since 2006, can prevent HPV transmission. We assessed trends in JORRP cases before and after HPV vaccine introduction in the United States.
Methods
Case-patients were identified from 26 pediatric otolaryngology centers in 23 U.S. states. Demographics and clinical history were abstracted from medical records. Case-patients were grouped by year of birth, and birth-cohort incidences were calculated using number of births from either national or state-level natality data from the 23 states. We calculated incidence rate ratios (IRR) and 95% confidence intervals (CI) in 2-year intervals.
Results
We identified 576 U.S. JORRP case-patients born in 2004–2013. Median age at diagnosis was 3.4 years (interquartile range: 1.9, 5.5). Number of identified JORRP case-patients declined from a baseline of 165 born in 2004–2005 to 36 born in 2012–2013. Incidence of JORRP per 100 000 births using national data declined from 2.0 cases in 2004–2005 to 0.5 cases in 2012–2013 (IRR = 0.2, 95% CI = .1–.4); incidence using state-level data declined from 2.9 cases in 2004–2005 to 0.7 cases in 2012–2013 (IRR = 0.2, 95% CI = .1–.4).
Conclusions
Over a decade, numbers of JORRP case-patients and incidences declined significantly. Incidences calculated using national denominator data are likely underestimates; those calculated using state-level denominator data could be overestimates. These declines are most likely due to HPV vaccination. Increasing vaccination uptake could lead to elimination of this HPV-related disease.
Prospective and retrospective data (2008–2017) from pediatric otolaryngology practices in 23 US states showed numbers of children with juvenile-onset recurrent respiratory papillomatosis (JORRP) and JORRP incidence have declined significantly. Declines are most likely due to human papillomavirus (HPV) vaccination.
We assessed the sensitivity of self-reported human papillomavirus (HPV) vaccination among young adult men who have sex with men (MSM) with documented HPV vaccination.
During 2016-2018, MSM and ...transgender women aged 18 to 26 years were enrolled in Seattle, WA. A history of HPV vaccination was assessed via self-administered survey, clinic electronic medical records, and the Washington State Immunization Information System. We assessed self-report sensitivity among participants with documented prior HPV vaccination (≥1 dose) in either the electronic medical record or the Washington State Immunization Information System, and used logistic regression to compare sensitivity by age, number of doses, and time since first dose.
Of 292 participants with ≥1 documented HPV vaccine dose, 243 self-reported ≥1 dose (sensitivity, 83.2%; 95% confidence interval CI, 78.4%-87.3%). Compared with participants whose first dose was <1 year ago, the likelihood of self-report was lower among those with ≥3 years since first dose (adjusted odds ratio aOR, 0.2; 95% CI, 0.1-0.5). Furthermore, compared with participants with only 1 documented HPV vaccine dose, the likelihood of self-reporting ≥1 dose was higher among those with 2 (aOR, 2.4; 95% CI, 1.0-5.5) or ≥3 doses (aOR, 6.2; 95% CI, 2.7-14.4). Among 115 participants with ≥3 documented doses, sensitivity for recalling ≥3 doses was 69.6% (95% CI, 60.3%-77.8%).
Most young adult MSM with a documented history of HPV vaccination self-reported prior HPV vaccination. Although recall was highest in those with ≥3 doses, 30% of this fully vaccinated subgroup did not correctly recall the number of doses received, highlighting limitations of self-reporting. Furthermore, results indicating reduced recall with ≥3 years since first dose suggest that sensitivity of self-report among young adult MSM may decline over time as adolescent vaccination coverage increases.
Objective:
High-quality scientific evidence underpins public health decision making. The Centers for Disease Control and Prevention (CDC) agency provides scientific data, including during public ...health emergencies. To understand CDC’s contributions to COVID-19 science, we conducted a bibliometric evaluation of publications authored by CDC scientists from January 20, 2020, through January 20, 2022, by using a quality improvement approach (SQUIRE 2.0).
Methods:
We catalogued COVID-19 articles with ≥1 CDC-affiliated author published in a scientific journal and indexed in the World Health Organization’s COVID-19 database. We identified priority topic areas from the agency’s COVID-19 Public Health Science Agenda by using keyword scripts in EndNote and then assessed the impact of the published articles by using Scopus and Altmetric.
Results:
During the first 2 years of the agency’s pandemic response, CDC authors contributed to 1044 unique COVID-19 scientific publications in 208 journals. Publication topics included testing (n = 853, 82%); prevention strategies (n = 658, 63%); natural history, transmission, breakthrough infections, and reinfections (n = 587, 56%); vaccines (n = 567, 54%); health equity (n = 308, 30%); variants (n = 232, 22%); and post–COVID-19 conditions (n = 44, 4%). Publications were cited 40 427 times and received 81 921 news reports and 1 058 893 social media impressions. As the pandemic evolved, CDC adapted to address new scientific questions, including vaccine effectiveness, safety, and access; viral variants, including Delta and Omicron; and health equity.
Conclusion:
The agency’s COVID-19 Public Health Science Agenda helped guide impactful scientific activities. CDC continues to evaluate COVID-19 priority topic areas and contribute to development of new scientific work. CDC is committed to monitoring emerging issues and addressing gaps in evidence needed to improve health.
Background
Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States; men who have sex with men (MSM) have higher prevalence of infection and related disease ...compared with other men. We assessed whether differences in HPV acquisition exist among MSM according to their sexual positioning practices, as well as self-reported receipt of HPV vaccination.
Methods
We enrolled young MSM and transgender women aged 18 to 26 years in Chicago, IL (N = 666). Participants self-reported their history of HPV vaccination and submitted self-collected anal swab specimens for type-specific HPV detection using an L1-consensus PCR assay. Multivariable logistic regression analyses were used to assess relationships between sexual positioning practices and detection of any HPV or quadrivalent HPV vaccine (4vHPV) types by vaccination status, defined as self-reported receipt of ≥1 HPV vaccine dose versus none.
Results
Among 666 participants, 400 (60.1%) had any anal HPV, and 146 (21.9%) had a 4vHPV type. Among vaccinated participants, 18, 36, and 177 reported exclusively insertive, exclusively receptive, or both sexual positioning practices, respectively. Compared with participants reporting exclusively insertive anal sex, odds of any HPV were significantly higher among participants engaging exclusively in receptive anal sex (adjusted odds ratio aOR, 5.90; 95% confidence interval CI, 2.52–13.78), as well as those engaging in both (aOR, 3.32; 95% CI, 1.71–6.44). Vaccinated participants, compared with unvaccinated participants, had lower odds of 4vHPV-type HPV regardless of sexual positioning practices (aOR, 0.56; 95% CI, 0.34–0.92).
Conclusions
Adult men and transgender women who practice anal receptive sex have high prevalence of infection with any HPV. Routine vaccination of all adolescents is expected to reduce HPV-related disease incidence among adult MSM and transgender women as vaccinated cohorts age.
Estimates of medical care costs for cervical and other cancers associated with human papillomavirus (HPV) are higher in studies published in recent years than in studies published before 2012. The ...purpose of this report is (1) to review and summarize the recent cancer cost estimates and (2) to illustrate how the estimated cost-effectiveness of HPV vaccination might change when these recent cost estimates are applied. Our literature search yielded 6 studies that provided updated medical care cost estimates for 5 HPV-associated cancers. We found that applying the current cancer cost estimates had a notable impact on the estimated medical costs averted by HPV vaccination over an extended time frame (100 years), and a moderate impact on the estimated cost per quality-adjusted life year (QALY) gained by HPV vaccination. For example, for catch-up vaccination of teenagers and young adults, applying the more recent cancer costs reduced the estimated cost per QALY gained by about $12,400. The cost studies we identified in our literature review are up-to-date and based on reliable data sources from United States settings, and can inform future studies of HPV vaccination cost-effectiveness in the United States. However, careful consideration is warranted to determine the most appropriate cost values to apply.
BACKGROUNDHuman papillomavirus (HPV) is a common sexually transmitted infection. Men who have sex with men (MSM) and transgender women (TGW) are at high risk for anal HPV infection and subsequent ...anal cancer. This study assessed the association of partner discordances with prevalent high-risk anal HPV (HRAHPV) among MSM and TGW.
METHODSParticipants were enrolled in the cross-sectional young menʼs HPV study of gay, bisexual, and other MSM, and TGW, aged 18 to 26 years, from 2 cities. Participants completed a confidential standardized computer-assisted interview and provided self-collected anal swabs for type-specific HPV DNA testing. Multivariate analyses were conducted for 3 discordances of interest (i.e., partner age, race/ethnicity, and concurrent partner) to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI).
RESULTSEight hundred sixty-two participants were included for partner race/ethnicity discordance, 601 for partner age discordance, and 581 for concurrent partner analysis. Most reported being older than 21 years, cisgender male, and gay. Adjusted odds of HRAHPV were not significantly increased among participants reporting partner age discrepancy >10 years (aOR, 0.89; 95% CI, 0.51–1.56), partner race/ethnicity discordance (aOR, 0.88; CI, 0.62–1.24), or partner with concurrent partners (aOR, 0.85; 95% CI, 0.50–1.42), compared with those who did not.
CONCLUSIONSThis analysis did not identify any partner discordances associated with HRAHPV. Because HPV infection can persist for years, sexual mixing patterns with early partners might be more relevant than the most recent sex partner. Prevalence of HRAHPV was high and could be preventable by preexposure vaccination, as recommended for everyone through age 26 years including MSM and TGW.
Gay, bisexual, and other men who have sex with men (MSM) and transgender women are disproportionately affected by human papillomavirus (HPV). HPV vaccination is routinely recommended for U.S. ...adolescents at age 11-12 years, with catch-up vaccination through age 26 years. We assessed HPV vaccination coverage and associated factors among young MSM and transgender women. The Vaccine Impact in Men study enrolled MSM aged 18-26 years from clinics in Seattle, Chicago, and Los Angeles, during February 2016-September 2018. Participants self-reported socio-demographic information and HPV vaccination status. Among 1416 participants, 673 (47.5%) reported ≥1 HPV vaccine dose. Among vaccinated participants, median age at first dose was 19 years and median age at first sex was 17 years; 493 (73.3%) reported that their age at first dose was older than their age at first sex. There were significant differences in HPV vaccination coverage by city (range 33%-62%), age, race/ethnicity, and gender identity. Coverage was highest in Seattle, where younger age was the only factor associated with vaccination. Differences in coverage by city may be due to variation in vaccination practices or enrollment at study sites. Increasing both routine and catch-up vaccination will improve coverage among MSM and transgender women.
Among 215 US children with juvenile-onset recurrent respiratory papillomatosis in 2015–2020, most were firstborn children delivered vaginally to young mothers; most mothers reported no human ...papillomavirus (HPV) vaccination before delivery. Vaccine-preventable HPV types were detected in almost all papilloma specimens tested.
Abstract
Background
Juvenile-onset recurrent respiratory papillomatosis (JORRP) is a rare disease characterized by the growth of papillomas in the respiratory tract. In the United States, JORRP is not a nationally notifiable condition and current data are limited.
Methods
Children with JORRP aged <18 years were enrolled from 26 pediatric otolaryngology centers in 23 US states from January 2015 through August 2020. Demographic, birth information, and maternal vaccination history were collected from a parent/guardian. Clinical history was abstracted from medical records. Papilloma biopsies were tested for 28 human papillomavirus (HPV) types. Mothers who delivered in 2006 or later were considered age-eligible for HPV vaccination if aged ≤26 years in 2006. We described characteristics of enrolled children and their birth mothers and analyzed disease severity by diagnosis age and HPV type using multiple logistic regression.
Results
Among 215 children with JORRP, 88.8% were delivered vaginally; 64.2% were firstborn. Among 190 mothers, the median delivery age was 22 years. Among 114 (60.0%) age-eligible for HPV vaccination, 16 (14.0%) were vaccinated, 1 (0.9%) before delivery. Among 162 specimens tested, 157 (96.9%) had detectable HPV; all 157 had a vaccine-preventable type. Disease severity was associated with younger diagnosis age and HPV 11; adjusted analyses found only younger diagnosis age significant (adjusted odds ratio: 6.1; 95% confidence interval: 2.9, 12.8).
Conclusions
Children with JORRP were commonly firstborn and delivered vaginally to young mothers; most of the mothers reported no HPV vaccination before delivery. Vaccine-preventable HPV was identified in all specimens with detectable HPV. Increasing preexposure HPV vaccination could substantially reduce or eliminate JORRP in the United States.
