RESUMO
BACKGROUND: The incidence of syphilis continues to increase in the United States, yet little is known about Treponema pallidum genomic epidemiology within American metropolitan areas. METHODS: We performed whole-genome sequencing and tprK deep sequencing of 28 T. pallidum-containing specimens, collected mostly from remnant Aptima swab specimens from 24 individuals from Seattle Sexual Health Clinic during 2021-2022. RESULTS: All 12 individuals infected with Nichols-lineage strains were men who have sex with men, while a specific SS14 cluster (mean, 0.33 single-nucleotide variant) included 1 man who has sex with women and 5 women. All T. pallidum strains sequenced were azithromycin resistant via 23S ribosomal RNA A2058G mutation. Identical T. pallidum genomic sequences were found in pharyngeal and rectal swab specimens taken concurrently from the same individuals. The tprK sequences were less variable between patient-matched specimens and between epidemiologically linked clusters. We detected a 528-base pair deletion in the tprK donor site locus, eliminating 9 donor sites, in T. pallidum genomes of 3 individuals with secondary syphilis, associated with diminution of TprK diversity. CONCLUSIONS: We developed an end-to-end workflow for public health genomic surveillance of T. pallidum from remnant Aptima swab specimens. tprK sequencing may assist in linking cases beyond routine T. pallidum genome sequencing. T. pallidum strains with deletions in tprK donor sites currently circulate and are associated with diminished TprK antigenic diversity.

BACKGROUND: In 2021, national Chlamydia trachomatis (CT) treatment guidelines changed from recommending either azithromycin (1 g; single dose) or doxycycline (100 mg twice daily for 7 days) to recommending only doxycycline as first-line treatment. The distribution and trends in CT prescribing practices before the guidelines change is largely unknown. METHODS: We conducted a trends analysis using Washington STD surveillance data. We included all female cases of urogenital CT 15 years or older who resided in King County and were diagnosed between 2010 and 2018. Surveillance data included information on demographics, sexual history, clinical features, diagnosing facility (eg, emergency department, family planning), and treatment regimen. We conducted descriptive analyses to examine trends in prescribing practices over time and by facility type. We used Poisson regression to examine the association between CT case characteristics and receipt of receipt of azithromycin. RESULTS: There were 36,830 cases of female urogenital CT during the study period. The percent of cases receiving azithromycin increased significantly from 86% in 2010 to 94% in 2018; the percent receiving doxycycline decreased from 13% to 5%. Five of the 8 facility types prescribed azithromycin to >95% of CT cases by 2018. Cases who were younger or cases of color were more likely to receive azithromycin (versus doxycycline) compared with older and White cases, respectively. CONCLUSIONS: A substantial shift in CT prescribing practices will be needed to adhere to new CT treatment guidelines. Our findings highlight the need for targeted provider education and training to encourage the transition to doxycycline use.

BACKGROUND: Promptly recognizing mpox can facilitate earlier diagnosis and appropriate treatment. How accurately clinicians can diagnose mpox based on clinical data and before receiving molecular test results is not known. METHODS: Leveraging public health and clinical data collected in Seattle-King County's Sexual Health Clinic (SHC) from July 29, 2022, to September 30, 2022, we analyzed the proportion of patients who received presumptive versus results-based tecovirimat when clinicians had a high, intermediate, or low suspicion for mpox after clinical evaluation. We calculated the sensitivity, specificity, and positive (PPV) and negative predictive value (NPV) of this approach against criterion standard mpox polymerase chain reaction (PCR) results. RESULTS: Of 321 patients evaluated for mpox in the SHC, median age was 34.5 years and 88% were cisgender men. Overall, 121 of 319 (38%) tested positive by mpox PCR. Clinicians had high suspicion for mpox in 122 patients and offered empiric tecovirimat to 92 (88%), of whom 85 (92%) tested PCR positive. Of 13 intermediate suspicion patients offered presumptive therapy, all accepted but none tested positive by PCR. The sensitivity, specificity, PPV, and NPV of high/intermediate clinical suspicion for mpox were 99%, 90%, 86%, and 99%, respectively. A higher proportion of people with HIV were diagnosed with mpox (57% vs. 36%, P = 0.01, χ2 test), and sensitivity and PPV of high/intermediate clinical suspicion in this subgroup were 100% and 86%, respectively. CONCLUSIONS: Clinical providers working in a high-volume, public SHC were able to both accurately identify and rule out mpox based on clinical examination before receiving PCR test results.

ABSTRACT: We conducted a retrospective cohort study of preexposure prophylaxis patients at the municipal Sexual Health Clinic in Seattle-King County, Washington from 2019 to 2021 to determine whether monthly check-in text messages impacted 4- and 6-month pre-exposure prophylaxis retention. Monthly check-ins did not appear to improve retention above and beyond open-ended texting and appointment reminders.

BACKGROUND: SARS-CoV-2 pandemic mitigation efforts resulted in reallocation of public health personnel, likely impacting provision of timely sexually transmitted infection partner services (PS). We describe PS outcomes before and during the pandemic in King County, WA. METHODS: We examined PS outcomes for syphilis and gonorrhea cases diagnosed in 2019 and 3 periods in 2020 (pre-lockdown: January 1, 2020-March 23, 2020; lockdown: March 24, 2020-June 5, 2020; post-lockdown: June 6, 2020-December 31, 2020). We described changes over time in 3 PS outcomes: cases initiated, interviewed, and with named sex partners. We calculated adjusted prevalence ratios (aPRs) with Poisson regression comparing these outcomes in the 2020 periods with 2019. RESULTS: Reported gonorrhea (4611 vs. 4179) and syphilis (665 vs. 586) cases declined from 2019 to 2020. In 2019, 60.7% of cases were initiated, compared with 42.1% before lockdown (aPR, 0.74; 95% confidence interval [CI], 0.70%-0.78%), 41.7% during lockdown (aPR, 0.79; 95% CI, 0.73-0.85), and 41.7% after lockdown (aPR, 0.81; 95% CI, 0.77-0.85). Among initiated cases, the proportion interviewed also seemed to drop in the 3 lockdown periods (52.4%, 41.0%, 44.1%) compared with 2019 (55.7%). However, in adjusted analyses, the prevalence of interview among case patients was only lower pre-lockdown (aPR, 0.91; 95% CI, 0.85-0.99), and higher during (aPR, 1.10; 95% CI, 1.01-1.20) and after (aPR, 1.12; 95% CI, 1.06-1.19). Interviewed patients named partners more often during (21.4%; aPR, 1.35; 95% CI, 1.05-1.74) and less often after lockdown (16.0%; aPR, 0.63; 95% CI, 0.51-0.79), compared with 2019 (26.6%). CONCLUSIONS: These results underscore the need for a trained public health worker reserve, and plans for deployment of existing workers and prioritization of cases to continue essential sexually transmitted infection public health activities during public health crises.

BACKGROUND: How often mpox causes asymptomatic infections, particularly among persons who have received the Modified Vaccinia Ankara (MVA) vaccine, is unknown. METHODS: We performed mpox polymerase chain reaction testing on rectal and pharyngeal specimens collected from symptomatic and asymptomatic patients at a sexual health clinic in Seattle, WA, between May 2022 and May 2023. Analyses evaluated the prevalence of asymptomatic or subclinical infection and, among persons with polymerase chain reaction-positive tests, the association of MVA vaccination status with the symptomatic infection. RESULTS: The study population included 1663 persons tested for mpox during 2353 clinic visits. Ninety-three percent of study participants were cisgender men and 96% were men who have sex with men. A total of 198 symptomatic patients (30%) had a first mpox-positive test during 664 visits. Eighteen patients (1.1%) tested during 1689 visits had asymptomatic or subclinical mpox based on a positive rectal or pharyngeal test done in the absence of testing done because of clinical suspicion for mpox. Fourteen (78%) of 18 persons with asymptomatic/subclinical mpox and 53 (26%) of 198 persons with symptomatic mpox had received at least 1 dose of the MVA vaccine ( P < 0.0001). Controlling for calendar month, study subjects who received 1 and 2 doses of MVA vaccine were 4.4 (95% confidence interval, 1.3-15) and 11.9 (3.6-40) times more likely to have asymptomatic versus symptomatic mpox, respectively, than persons who were unvaccinated. CONCLUSIONS: Asymptomatic mpox is uncommon. Modified Vaccinia Ankara vaccination is associated with an asymptomatic/subclinical infection among persons with mpox.

BACKGROUND: Sexual health clinics were frontline providers in the 2022 US mpox public health response, though data on clinic-based mpox vaccine scale-up, diagnoses, and treatment are limited. We describe the role of a public health sexual health clinic (SHC) in King County's mpox response, between 5/23/22-10/31/22. METHODS: In July 2022, the SHC implemented a dedicated vaccine clinic and presumptive tecovirimat treatment (prior to laboratory confirmation) with on-site dispensation. We describe SHC's vaccine scale-up and contribution to clinical care by calculating the weekly number of vaccines administered by SHC and the total number of patients diagnosed and treated for mpox within SHC, and comparing to countywide data. We calculated time from symptom onset to testing and time from testing to treatment, and assessed temporal changes in these metrics using linear regression. RESULTS: The SHC provided ≥1 vaccine doses to 7,442 individuals (10,295 doses), administering 42% of the 24,409 vaccine doses provided countywide, with the greatest contribution in the first week of August (n = 1,562, 58% of countywide vaccinations that week). Of 598 patients evaluated for mpox and tested, 178 (30%) tested positive (37% of countywide cases), and 152 (85% of SHC patients with mpox) received tecovirimat (46% of treatment countywide). Median time from symptom onset to testing decreased from 12 to 6 days (p = 0.045); time from testing to treatment decreased from 4.5 days to 0 days (p < 0.001). CONCLUSION: The SHC was central to mpox vaccination and treatment scale-up, particularly in the first months of the 2022 epidemic.
RESUMO
BACKGROUND: Sexual behavior may influence the composition of the male urethral microbiota, but this hypothesis has not been tested in longitudinal studies of men who have sex with men (MSM). METHODS: From December 2014 to July 2018, we enrolled MSM with nongonococcal urethritis (NGU) attending a sexual health clinic. Men attended 5 in-clinic visits at 3-week intervals, collected weekly urine specimens at home, and reported daily antibiotics and sexual activity on weekly diaries. We applied broad-range 16S rRNA gene sequencing to urine. We used generalized estimating equations to estimate the association between urethral sexual exposures in the prior 7 days (insertive oral sex [IOS] only, condomless insertive anal intercourse [CIAI] only, IOS with CIAI [IOS + CIAI], or none) and Shannon index, number of species (observed, oral indicator, and rectal indicator), and specific taxa, adjusting for recent antibiotics, age, race/ethnicity, HIV, and preexposure prophylaxis. RESULTS: Ninety-six of 108 MSM with NGU attended ≥1 follow-up visit. They contributed 1140 person-weeks of behavioral data and 1006 urine specimens. Compared with those with no urethral sexual exposures, those with IOS only had higher Shannon index ( P = 0.03 ) but similar number of species and presence of specific taxa considered, adjusting for confounders; the exception was an association with Haemophilus parainfluenzae . CIAI only was not associated with measured aspects of the urethral microbiota. IOS + CIAI was only associated with presence of H. parainfluenzae and Haemophilus . CONCLUSIONS: Among MSM after NGU, IOS and CIAI did not seem to have a substantial influence on measured aspects of the composition of the urethral microbiota.

BACKGROUND: Over one-third of people living with HIV (PLH) in Ukraine are not on treatment. Index testing services, which link potentially exposed partners (named partners) of known PLH (index patients) with testing and treatment services, are being scaled in Ukraine and could potentially close this gap. METHODS: This retrospective study included patient data from 14,554 adult PLH who initiated antiretroviral treatment (ART) between October 2018 and May 2021 at one of 35 facilities participating in an intervention to strengthen index testing services. Mixed effects modified Poisson models were used to assess differences between named partners and other ART initiators, and an interrupted time series (ITS) analysis was used to assess changes in ART initiation over time. RESULTS: Compared to other ART initiators, named partners were significantly less likely to have a confirmed TB diagnosis (aRR = 0.56, 95% CI = 0.40, 0.77, p < 0.001), a CD4 count less than 200 cells/mm3 (aRR = 0.84, 95% CI = 0.73, 0.97, p = 0.017), or be categorized as WHO HIV stage 4 (aRR = 0.68, 9% CI = 0.55, 0.83, p < 0.001) at the time of ART initiation, and were significantly more likely to initiate ART within seven days of testing for HIV (aRR = 1.36, 95% CI = 1.22, 1.50, p < 0.001). Our ITS analysis showed a modest 2.34% (95% CI = 0.26%, 4.38%; p = 0.028) month-on-month reduction in mean ART initiations comparing the post-intervention period to the pre-intervention period, although these results were likely confounded by the COVID epidemic. CONCLUSION: Our findings suggest that index testing services may be beneficial in bringing PLH into treatment at an earlier stage of HIV disease and decreasing delays between HIV testing and ART initiation, potentially improving patient outcomes and retention in the HIV care cascade.

Low-barrier care (LBC) for people with human immunodeficiency virus (HIV) is a differentiated service delivery strategy to engage people in HIV treatment who are not well-engaged in conventionally organized HIV medical care. The LBC approach is flexible, but experience suggests that the intervention has distinct core components. This review summarizes our experience implementing one model of LBC, the Max Clinic in Seattle; describes the core components of the intervention; and presents a framework for implementing low-barrier HIV care with the goal of providing a practical guide for clinical and public health leaders seeking to implement a new LBC program. A systematic approach to addressing key factors during LBC implementation can support practitioners to design an LBC approach that fits the local context while maintaining essential elements of the intervention.

BACKGROUND: There is conflicting evidence on whether prior azithromycin (AZM) exposure is associated with reduced susceptibility to AZM (AZMRS) among persons infected with Neisseria gonorrhoeae (NG). METHODS: The study population included Public Health-Seattle and King County Sexual Health Clinic (SHC) patients with culture-positive NG infection at ≥1 anatomic site whose isolates were tested for AZM susceptibility in 2012-2019. We used multivariate logistic regression to examine the association of time since last AZM prescription from the SHC in ≤12 months with subsequent diagnosis with AZMRS NG (minimum inhibitory concentration [MIC], ≥2.0 µg/mL) and used linear regression to assess the association between the number of AZM prescriptions in ≤12 months and AZM MIC level, controlling for demographic, behavioral, and clinical characteristics. RESULTS: A total of 2155 unique patients had 2828 incident NG infections, 156 (6%) of which were caused by AZMRS NG. AZMRS NG was strongly associated with receipt of AZM from the SHC in the prior 29 days (adjusted odds ratio, 6.76; 95% confidence interval [CI], 1.76 to 25.90) but not with receipt of AZM in the prior 30-365 days. Log AZM MIC level was not associated with the number of AZM prescriptions within ≤12 months (adjusted correlation, 0.0004; 95% CI, -.04 to .037) but was associated with number of prescriptions within <30 days (adjusted coefficient, 0.56; 95% CI, .13 to .98). CONCLUSIONS: Recent individual-level AZM treatment is associated with subsequent AZMRS gonococcal infections. The long half-life and persistence of subtherapeutic levels of AZM may result in selection of resistant NG strains in persons with recent AZM use.

BACKGROUND: Mycoplasma genitalium (MG) is on the CDC Watch List of Antimicrobial Resistance Threats, yet there is no systematic surveillance to monitor change. METHODS: We initiated surveillance in sexual health clinics in 6 cities, selecting a quota sample of urogenital specimens tested for gonorrhea and/or chlamydia. We abstracted patient data from medical records and detected MG and macrolide-resistance mutations (MRMs) by nucleic acid amplification testing. We used Poisson regression to estimate adjusted prevalence ratios (aPRs) and 95% CIs, adjusting for sampling criteria (site, birth sex, symptom status). RESULTS: From October-December 2020 we tested 1743 urogenital specimens: 57.0% from males, 46.1% from non-Hispanic Black persons, and 43.8% from symptomatic patients. MG prevalence was 16.6% (95% CI: 14.9-18.5%; site-specific range: 9.9-23.5%) and higher in St Louis (aPR: 1.9; 1.27-2.85), Greensboro (aPR: 1.8; 1.18-2.79), and Denver (aPR: 1.7; 1.12-2.44) than Seattle. Prevalence was highest in persons <18 years (30.4%) and declined 3% per each additional year of age (aPR: .97; .955-.982). MG was detected in 26.8%, 21.1%, 11.8%, and 15.4% of urethritis, vaginitis, cervicitis, and pelvic inflammatory disease (PID), respectively. It was present in 9% of asymptomatic males and 15.4% of asymptomatic females, and associated with male urethritis (aPR: 1.7; 1.22-2.50) and chlamydia (aPR: 1.7; 1.13-2.53). MRM prevalence was 59.1% (95% CI: 53.1-64.8%; site-specific range: 51.3-70.6%). MRMs were associated with vaginitis (aPR: 1.8; 1.14-2.85), cervicitis (aPR: 3.5; 1.69-7.30), and PID cervicitis (aPR: 1.8; 1.09-3.08). CONCLUSIONS: MG infection is common in persons at high risk of sexually transmitted infections; testing symptomatic patients would facilitate appropriate therapy. Macrolide resistance is high and azithromycin should not be used without resistance testing.

OBJECTIVES: Epidemiological treatment of persons who are sexual contacts to partners with Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) often results in treatment of uninfected persons, which may increase the risk of antibiotic-resistant infections. We sought to identify the predictors of NG and/or CT infections to develop a risk score that could be used to limit epidemiological treatment to persons most likely to have these infections. METHODS: We included visits to the Public Health - Seattle & King County Sexual Health Clinic by asymptomatic cisgender men who have sex with men (MSM) aged ≥18 who presented as a sexual contact to partner(s) with CT or NG infection between 2011 and 2019. We used logistic regression to estimate the odds of CT and/or NG infections associated with demographic and clinical predictors, selecting the final set of predictors using the Akaike information criteria and obtaining score weights from model coefficients. We used a cross-validation approach to obtain average model discrimination from each of 10 models, leaving out 10% of the data, and evaluated sensitivity and specificity at various score cut-offs. RESULTS: The final model for predicting NG or CT infection included seven predictors (age <35 years, HIV status, receptive oral sex in the prior 2 months, CT diagnosis, condomless receptive anal intercourse, condomless insertive anal intercourse and methamphetamine use in the prior 12 months). Model discrimination, as measured by the receiver operating curve, was 0.60 (95% CI 0.54 to 0.66). Sensitivity for detection of infection was ≥90% for scores ≥3, ≥5 and ≥7; specificity for these cut-offs was <16%. At scores ≥9, ≥12 and ≥14, specificity increased but sensitivity decreased to ≤76%. CONCLUSIONS: Our risk score did not sufficiently discriminate between asymptomatic MSM with and without NG/CT infection. Additional studies evaluating epidemiological treatment as a standard of care in diverse populations are needed to guide best practices in the management of contacts to NG/CT infection.

ABSTRACT: Case investigation and contact tracing (CICT) is a longstanding cornerstone of public health disease control efforts for a wide array of communicable diseases, though the content of CICT varies substantially depending on the infection to which it is applied, the epidemiologic circumstances, and interventions available to control an epidemic. In this article, we discuss how CICT is currently used in public health communicable disease, sexually transmitted infection/human immunodeficiency virus, and tuberculosis control programs. We then review how CICT might be modernized, considering issues such as community and health care organization engagement, workforce development, public health program organizational structure, data information systems, case prioritization, and the content to CICT.

BACKGROUND: Current guidance from the US Centers for Disease Control and Prevention recommends empiric treatment for persons exposed to sexually transmitted infections, including Neisseria gonorrhoeae ( NG ). As an antimicrobial stewardship measure, some clinics now recommend a test and treat strategy, but reliance on urogenital testing only may miss cases. METHODS: We conducted a descriptive analysis of pharyngeal NG infection in men who have sex with women (MSW) and women seeking care at a sexual health clinic in Seattle, WA, from February 2017 to July 2021 because of sexual contact to a partner diagnosed with gonorrhea. We also explored behavioral factors associated with pharyngeal NG positivity (by culture or nucleic acid amplification test by χ2 analysis. RESULTS: Among 352 NG contacts tested for urogenital or pharyngeal infection, 34% were positive for NG at ≥1 anatomic site (27% for MSW and 40% for women). Among 161 NG contacts tested at the pharynx, 30% (n = 48) were positive: 20% of 54 MSW (n = 11) and 35% (n = 37) of 107 women. If only urogenital testing were performed, 36% of MSW NG infections (n = 5) and 19% of female NG infections (n = 9) would have remained unidentified. CONCLUSIONS: Pharyngeal NG is relatively common among MSW and women who have been exposed to NG, and likely represents an underdiagnosed reservoir of NG infection. If empiric treatment is abandoned in favor of testing and treating, testing the throats of heterosexuals will be necessary.

BACKGROUND: Anecdotal reports suggest that partner services (PS) are less successful among people with repeat sexually transmitted infection (STI) diagnoses and/or previous PS interactions. We examine whether having repeated STI diagnoses and/or PS interactions is associated with PS outcomes among men who have sex with men (MSM). METHODS: With STI surveillance and PS data for MSM diagnosed with gonorrhea, chlamydia, and/or syphilis from 2007 to 2018, in King County, WA, we used Poisson regression models to examine the relationships between PS outcomes (e.g., completing a PS interview and providing identifying information for a contact) with (1) number of previous STI case episodes and (2) number of previous PS interviews completed. RESULTS: Of the 18,501 MSM STI case patients initiated for interview in the analytic period (2011-2018), 13,232 (72%) completed a PS interview, and 8,030 (43%) had at least 1 prior PS interview. The proportion of initiated cases successfully interviewed declined from 71% among those with no previous PS interview to 66% among those with ≥3 prior interviews. Similarly, the proportion of interviews with ≥1 partner identified declined with greater numbers of previous PS interviews (from 46% [0 interviews] to 35% [≥3 interviews]). In multivariate models, having ≥1 prior PS interview was negatively associated with completing a subsequent interview and providing partner locating information. CONCLUSIONS: Having a history of STI PS interviews is associated with less PS engagement among MSM. New approaches to PS should be explored to address the growing epidemic of STIs among MSM.

Low-barrier care is one model of a differentiated service delivery approach for people with HIV (PWH) who are not engaged in conventionally-organized HIV care. Although psychiatric and substance use disorders are common among patients in low-barrier clinics, approaches to behavioral health service delivery within this context have not been well-described. We conducted a descriptive analysis using retrospective review of medical records to evaluate substance use and psychiatric comorbidities and receipt of behavioral health services among patients in the Max Clinic in Seattle, Washington. Among 227 patients enrolled from 2015 to mid-2020, most had a history of hazardous substance use (85%), a psychiatric diagnosis (69%) or unstable housing (69%) documented in the medical record. Less than half of patients referred for depression treatment (33%) or for opioid use disorder treatment (40%) completed even one specialty care visit. More effective approaches are needed to engage patients in behavioral health services within the context of low-barrier HIV care.

National trends in gonorrhea rates may obscure informative local variations in morbidity. We used group-based trajectory models to identify groups of counties with similar gonorrhea rate trajectories among non-Hispanic White (NHW) and non-Hispanic Black (NHB) females using county-level data on gonorrhea cases in US females from 2003 to 2018. We assessed models with 1-15 groups and selected final models based on fit statistics and identification of divergent trajectory groups with distinct intercepts and/or slopes. We mapped counties by assigned trajectory group and examined the association of county characteristics with group membership. We identified 7 distinct gonorrhea trajectory groups for NHW females and 9 distinct trajectory groups for NHB females. All identified groups for NHW female morbidity experienced increasing gonorrhea rates with a limited range (11.6-183.3/100,000 NHW females in 2018); trajectories of NHB female morbidity varied widely in rates (146.6-966.0/1000 NHB females in 2018) and included 3 groups of counties that experienced a net decline in gonorrhea rates. Counties with higher NHW female morbidity had lower adult sex ratios, lower health insurance coverage, and lower marital rates among NHW adults. Counties with higher NHB female morbidity were more urban, experienced higher rates of poverty, and had lower rates of marriage among NHB adults. Morbidity patterns did not always follow geographic proximity, which could be explained by variation in social determinants of health. Our results demonstrated a highly heterogenous gonorrhea epidemic among NHW and NHB US females, which should prompt further analysis into the differential drivers of gonorrhea morbidity.

Although nuanced parameterization of sexual behavior may improve estimates from mathematical models of human immunodeficiency virus and sexually transmitted infection transmission, prospective estimates of the incidence of specific sexual behaviors among men who have sex with men (MSM) are limited. From December 2014 to July 2018, MSM with and without nongonococcal urethritis (NGU) completed weekly diaries over 3-12 weeks. Incidence rates of any sex, receptive anal sex, insertive anal sex, insertive oral sex, receptive rimming, and receptive hand-penile contact were 1.19, 0.28, 0.66, 0.90, 0.24, and 0.85 episodes per person-week, respectively, among 104 MSM with NGU at baseline, and 1.33, 0.54, 0.32, 0.95, 0.44, and 0.88 episodes per person-week, respectively, among 25 MSM without NGU at baseline. Most receptive anal sex (NGU + 83%, NGU - 86%) and insertive anal sex (NGU + 85%, NGU - 76%) episodes were condomless. MSM engaged in sex just over once per week, and condom use was infrequent. Insertive oral sex and receptive hand-penile contact were the most common behaviors.

BACKGROUND: In the United States, human papillomavirus (HPV) vaccination has been recommended since 2011 for boys aged 11-12 years, with catch-up vaccination recommended through age 26 years for previously unvaccinated men who have sex with men (MSM). METHODS: During 2016-2018, a cross-sectional study enrolled MSM and transgender women aged 18-26 years in Seattle, Washington. Participants submitted self-collected penile swab specimens for HPV genotyping. HPV vaccination history was self-reported. We compared HPV prevalence among vaccinated participants with that in participants with no or unknown vaccination history, using log-binomial regression to estimate adjusted prevalence ratios and confidence intervals. RESULTS: Among 687 participants, 348 (50.7%) self-reported ever receiving ≥1 HPV vaccine dose; the median age at first HPV vaccination was 21 years, and the median age at first sex, 17 years. Overall, the prevalence of penile quadrivalent HPV vaccine (4vHPV)-type HPV was similar in vaccinated participants (12.1%) and participants with no or unknown vaccination (15.6%) (adjusted prevalence ratio, 0.69 [95% confidence interval, .47-1.01]). However, the prevalence was significantly lower in participants vaccinated at age ≤18 years than in those with no of unknown vaccination (0.15 [.04-.62]), corresponding to a vaccine effectiveness of 85% against 4vHPV-type HPV. CONCLUSIONS: Results suggest that HPV vaccination is effective in preventing penile HPV infections in young MSM when administered at age ≤18 years.
