Abstract
As the United States faces a worsening epidemic of sexually transmitted infections (STIs), emergency departments (EDs) play a critical role in identifying and treating these infections. The growing health inequities in the distribution and disproportionate impact of STIs add to the urgency of providing high-quality sexual health care through the ED. Changes in population health are reflected in the new Centers for Disease Control recommendations on screening, diagnostic testing, and treatment of STIs. This review covers common, as well as and less common or emerging STIs, and discusses the state-of-the-art guidance on testing paradigms, extragenital sampling, and antimicrobial treatment and prevention of STIs.

Evaluation of Self-Collected Versus Health Care Professional (HCP)-Performed Sampling and the Potential Impact on the Diagnostic Results of Asymptomatic Sexually Transmitted Infections (STIs) in High-Risk Individuals. Infect Dis Rep 2023; 15:470-477. [PMID: 37736994 PMCID: PMC10514875 DOI: 10.3390/idr15050047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 08/20/2023] [Accepted: 08/23/2023] [Indexed: 09/23/2023] Open
Abstract
Sexually transmitted infections (STIs) are increasing among men who have sex with men (MSM). Screening can improve the detection and outcome of asymptomatic STIs in high-risk populations. Self-sampling may be a resource-optimized strategy; however, its diagnostic reliability compared to testing by healthcare professionals (HCPs) requires further investigation. In this prospective, multicenter cohort study in a high-income country, asymptomatic MSM with a sexual risk profile for STIs were included. Sequential swabs for STI nucleic acid-based diagnosis of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) were performed after randomization, either through self-sampling or HCP-performed sampling. Baseline demographic information, sexual risk behavior, and acceptance and feedback on self-sampling were recorded using an electronic questionnaire. Out of 236 asymptomatic MSM, 47 individuals (19.9%) tested positive for CT and/or NG through self- or HCP-performed sampling. For CT, the sensitivity was 93.3% for both sampling methods, while for NG, it was 90.0% for self-sampling and 95.0% for HCP-performed sampling. Our study demonstrates that self-sampling for asymptomatic STIs has a comparable diagnostic outcome to HCP-performed sampling, with high acceptance in high-risk MSM.

Self-sampling strategies (with/without digital innovations) in populations at risk of Chlamydia trachomatis and Neisseria gonorrhoeae: a systematic review and meta-analyses. Sex Transm Infect 2023; 99:420-428. [PMID: 36990696 PMCID: PMC10447399 DOI: 10.1136/sextrans-2022-055557] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 02/24/2023] [Indexed: 03/31/2023] Open
Abstract
BACKGROUND Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) resulted in over 200 million new sexually transmitted infections last year. Self-sampling strategies alone or combined with digital innovations (ie, online, mobile or computing technologies supporting self-sampling) could improve screening methods. Evidence on all outcomes has not yet been synthesised, so we conducted a systematic review and meta-analysis to address this limitation. METHODS We searched three databases (period: 1 January 2000-6 January 2023) for reports on self-sampling for CT/GC testing. Outcomes considered for inclusion were: accuracy, feasibility, patient-centred and impact (ie, changes in linkage to care, first-time testers, uptake, turnaround time or referrals attributable to self-sampling).We used bivariate regression models to meta-analyse accuracy measures from self-sampled CT/GC tests and obtain pooled sensitivity/specificity estimates. We assessed quality with Cochrane Risk of Bias Tool-2, Newcastle-Ottawa Scale and Quality Assessment of Diagnostic Accuracy Studies-2 tool. RESULTS We summarised results from 45 studies reporting self-sampling alone (73.3%; 33 of 45) or combined with digital innovations (26.7%; 12 of 45) conducted in 10 high-income (HICs; n=34) and 8 low/middle-income countries (LMICs; n=11). 95.6% (43 of 45) were observational, while 4.4% (2 of 45) were randomised clinical trials.We noted that pooled sensitivity (n=13) for CT/GC was higher in extragenital self-sampling (>91.6% (86.0%-95.1%)) than in vaginal self-sampling (79.6% (62.1%-90.3%)), while pooled specificity remained high (>99.0% (98.2%-99.5%)).Participants found self-sampling highly acceptable (80.0%-100.0%; n=24), but preference varied (23.1%-83.0%; n=16).Self-sampling reached 51.0%-70.0% (n=3) of first-time testers and resulted in 89.0%-100.0% (n=3) linkages to care. Digital innovations led to 65.0%-92% engagement and 43.8%-57.1% kit return rates (n=3).Quality of studies varied. DISCUSSION Self-sampling had mixed sensitivity, reached first-time testers and was accepted with high linkages to care. We recommend self-sampling for CT/GC in HICs but additional evaluations in LMICs. Digital innovations impacted engagement and may reduce disease burden in hard-to-reach populations.

Lessons Learned From the Implementation of a Pilot Study on Self-collected Specimen Return by Sexual Minority Men (Project Caboodle!): Qualitative Exploration. JMIR Form Res 2023; 7:e43539. [PMID: 37023442 PMCID: PMC10131702 DOI: 10.2196/43539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 03/02/2023] [Accepted: 03/03/2023] [Indexed: 04/08/2023] Open
Abstract
BACKGROUND Self-collection of specimens at home and their return by mail might help reduce some of the barriers to HIV and bacterial sexually transmitted infection (STI) screening encountered by gay, bisexual, and other men who have sex with men (GBMSM). To evaluate the benefits and challenges of bringing this approach to scale, researchers are increasingly requesting GBMSM to return self-collected specimens as part of web-based sexual health studies. Testing self-collected hair samples for preexposure prophylaxis drug levels may also be a viable option to identify GBMSM who face adherence difficulties and offer them support. OBJECTIVE Project Caboodle! sought to evaluate the acceptability and feasibility of self-collecting at home and returning by mail 5 specimens (a finger-stick blood sample, a pharyngeal swab, a rectal swab, a urine specimen, and a hair sample) among 100 sexually active GBMSM in the United States aged between 18 and 34 years. In this manuscript, we aimed to describe the key lessons learned from our study's implementation and to present recommendations offered by participants to maximize the rates of self-collected specimen return. METHODS Following the specimen self-collection phase, a subset of 25 participants (11 who returned all 5 specimens, 4 who returned between 1 and 4 specimens, and 10 who did not return any specimens) was selected for in-depth interviews conducted via a videoconferencing platform. During the session, a semistructured interview guide was used to discuss the factors influencing decisions regarding returning self-collected specimens for laboratory processing. The transcripts were analyzed using template analysis. RESULTS University branding of web-based and physical materials instilled a sense of trust in participants and increased their confidence in the test results. Shipping the specimen self-collection box in plain unmarked packaging promoted discretion during transit and on its receipt. Using different colored bags with matching color-coded instructions to self-collect each type of specimen minimized the potential for confusion. Participants recommended including prerecorded instructional videos to supplement the written instructions, providing information on the importance of triple-site bacterial STI testing, and adding a reminder of the types of testing that would and would not be conducted on hair samples. Participants also suggested tailoring the specimen self-collection box to include only the tests that they might be interested in completing at that time, adding real-time videoconferencing to the beginning of the study to introduce the research team, and sending personalized reminders following the delivery of the specimen self-collection box. CONCLUSIONS Our results offer valuable insights into aspects that facilitated participant engagement in self-collected specimen return, as well as areas for potential improvement to maximize return rates. Our findings can help guide the design of future large-scale studies and public health programs for home-based HIV, bacterial STI, and preexposure prophylaxis adherence testing.

Abstract
Few studies among gay, bisexual and other men who have sex with men (GBMSM) have examined facilitators and barriers to self-collecting specimens for extragenital STI screening, and none have evaluated attitudes towards self-collecting hair samples that can be utilized for PrEP drug level testing to assess adherence. To address this gap, we interviewed 25 sexually active GBMSM who were offered a choice to self-collect and return finger-stick blood samples (for actual HIV testing), pharyngeal swabs, rectal swabs and urine specimens (for actual gonorrhea and chlamydia testing), and hair samples (to visually determine their adequacy for PrEP drug level testing): 11 who returned all, 4 who returned some, and 10 who did not return any. Participants found self-collecting finger-stick blood samples and rectal swabs more challenging than other specimens. Frequently discussed facilitators of return included an opportunity to confirm one's HIV or STI status, limited access to a healthcare provider and a desire to advance research focusing on home-based testing. Commonly cited barriers to return included low self-efficacy pertaining to self-collection and apprehension around the possibility of delay or loss of specimens during transit. Offering additional support such as real-time video conferencing may prove helpful in future field-based research with GBMSM.

Abstract
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.

Abstract
In response to rising rates of bacterial sexually transmitted infections (STIs) in the United States, this evaluative study of the implementation of four evidence-based interventions was developed and implemented. In three STI and HIV high-incidence jurisdictions of the United States, nine federally funded Health Resources and Services Administration Ryan White HIV/AIDS Program clinical demonstration sites implemented (1) audio computer-assisted self-interview sexual history taking, (2) patient self-collection of urogenital and extragenital site chlamydia/gonorrhea nucleic acid amplification test specimens, (3) sexual and gender minority welcoming indicators, and (4) provider training, to make STI screening, testing, and treatment routine in their HIV primary care clinics. The priority populations of young adults, men who have sex with men, and sexual and gender minority patients were found to have risk behaviors identified in the self-interview sexual history, to prefer to self-collect urogenital and extragenital site specimens for STI testing, and to notice and like the sexual and gender minority welcoming indicators. Testing positive for a bacterial STI was significantly associated with using alcohol or recreational drugs before sex, being younger than 50 years, and having two or more sexual partners with other concurrent sexual partners. Of 255 cases of chlamydia, gonorrhea, and syphilis infections, only 13.73% of patients reported related symptoms when screened and tested.

Abstract
BACKGROUND Innovation is needed to produce sustained improvements in bacterial sexually transmitted infections (STI) testing given suboptimal access and uptake among sexually active gay, bisexual or other men who have sex with men (GBM). Yet, the STI testing processes and technologies that best address local testing barriers among GBM in Toronto is unknown. We aimed to explore men's perspectives regarding STI testing services for GBM to identify and prioritize new STI testing interventions in Toronto, Ontario, Canada. METHODS We conducted four focus groups with twenty-seven GBM in 2017: two with cisgender men living with HIV, one with cisgender HIV-negative men, and one with transgender men. Twenty-seven men participated in the focus groups with 40% 18-30 years of age, 48% self-identifying as white, and the remainder self-identifying as Middle Eastern, Latino/Hispanic, Asian/Pacific Islander, South Asian, First Nations, African/Caribbean/Black, or mixed race. 59% of participants self-identified as living with HIV. Participants were asked about their STI testing experiences in Toronto, barriers and facilitators to testing, and ideal STI testing process. Focus groups were audio recorded, transcribed verbatim, and analyzed using thematic analysis. RESULTS Core concepts included how clinical context, bacterial STI testing delivery, and interactions with healthcare providers can create barriers and recommendations for ways to improve. Regarding clinical context, participants desired more clinics with accessible locations/hours; streamlined testing that minimized use of waiting rooms and wait times; and improved clinic ambience. Bacterial STI testing delivery recommendations included standardization to ensure consistency in sexual history intake, tests offered, follow-up and public health reporting between clinics. Men also recommended reducing the multistep process testing by offering components such as lab requisitions and results online. Participants also recommended interactions with healthcare providers be professional and non-judgmental, offer compassionate and competent care with destigmatizing and lesbian, gay, bisexual and trans (LGBT) affirming communication. CONCLUSION Concrete and practical solutions for improving existing sexual health services and facilitating optimal STI testing include streamlining testing options and providing patient-centred, LGBT-affirming care to enable optimal STI testing.

Abstract
Objective: Sexually transmitted infections (STIs) are at unprecedented levels; yet most college students have never been tested. Offering asymptomatic individuals the option to collect their own samples for STI testing is an effective strategy to increase testing coverage. This study explores students' perceptions of self-collection services. Participants: Four hundred and thirty-four (434) students from a large public university completed an online survey in February 2018. Methods: The cross-sectional survey assessed students' human immunodeficiency virus (HIV)/STI testing behaviors, comfort with self-collection procedures, and intention to use self-collection services if offered on campus. Results: Most students (88%) said they would use self-collection test kits they could take home, followed by self-collection in a private room at student health services (59%). Students were most comfortable with testing procedures involving less human interaction and collecting specimens themselves. Cost, accuracy, confidentiality of tests, and provision of clear "how to" instructions, topped students' concerns. Conclusion: Offering self-collection options may increase STI testing among asymptomatic college students.

Abstract
Web-based HIV and sexually transmitted infection (STI) prevention studies are
increasingly requesting gay, bisexual, and other men who have sex with men
(GBMSM) to return self-collected specimens for laboratory processing. Some
studies have solicited self-collected extragenital swabs for gonorrhea and
chlamydia testing, but to date, none have solicited self-collected hair samples
for pre-exposure prophylaxis (PrEP) adherence testing. Project Caboodle! offered
100 racially/ethnically diverse GBMSM aged 18 to 34 years residing across the
United States a choice to self-collect at home and return by mail any of the
following: a finger-stick blood sample (for HIV testing), a pharyngeal swab, a
rectal swab and a urine specimen (for gonorrhea and chlamydia testing), and a
hair sample (to visually assess its adequacy for PrEP drug level testing).
Despite not incentivizing specimen return, 51% mailed back at least one type of
specimen within 6 weeks (1% returned three specimens, 11% returned four
specimens and 39% returned all five specimens). The majority of returned
specimens were adequate for laboratory processing. Significantly more
participants without a college education (p = .0003) and those
who were working full-time or part-time (p = .0070) did not
return any specimens. In addition, lower levels of HIV-related knowledge
(p = .0390), STI-related knowledge (p =
.0162), concern about contracting HIV (p = .0484), and concern
about contracting STIs (p = .0108) were observed among
participants who did not return any specimens. Self-collection of specimens
holds promise as a remote monitoring strategy that could supplement testing in
clinical settings, but a better understanding of why some GBMSM may choose to
fully, partially, or not engage in this approach is warranted.

Improving sexually transmitted infection screening, testing, and treatment among people with HIV: A mixed method needs assessment to inform a multi-site, multi-level intervention and evaluation plan.

Abstract
Bacterial sexually transmitted infections (STIs) continue to be a worsening public health concern in the United States (US). Though the national incidence of HIV infection has decreased over recent years, that of chlamydia, gonorrhea, and syphilis have not. Despite national recommendations on prevention, screening, and treatment of these STIs, these practices have not been standardized. Nine Health Resources and Services Administration Ryan White HIV/AIDS Program funded clinics across 3 US jurisdictions (Florida, Louisiana, and Washington, DC), were selected as clinical demonstration sites to be evaluated in this mixed method needs assessment to inform a multi-site, multi-level intervention to evaluate evidence-based interventions to improve STI screening and testing of bacterial STIs among people with or at risk for HIV. These 3 US jurisdictions were selected due to having higher than national average incidence rates of HIV and bacterial STIs. Descriptive statistics and deductive analysis were used to assess quantitative and qualitative needs assessment data. Results indicate the following needs across participating sites: inconsistent and irregular comprehensive sexual behavior history taking within and among sites, limited routine bacterial STI testing (once/year and if symptomatic) not in accordance with CDC recommendations, limited extragenital site gonorrhea/chlamydia testing, limited annual training on STI-related topics including LGBTQ health and adolescent/young adult sexual health, and limited efforts for making high-STI incidence individuals feel welcome in the clinic (primarily LGBTQ individuals and adolescents/young adults). These findings were used to identify interventions to be used to increase routine screenings and testing for bacterial STIs.

Diagnostic tests for detecting Chlamydia trachomatis and Neisseria gonorrhoeae in rectal and pharyngeal specimens. J Clin Microbiol 2021; 60:e0021121.

Abstract
Chlamydia trachomatis and Neisseria gonorrhoeae are two of the most often reported bacterial infections in the United States. The rectum and oropharynx are important anatomic sites of infection and can contribute to ongoing transmission. Nucleic acid amplification tests (NAATs) are the mainstays for the detection of C. trachomatis and N. gonorrhoeae infections owing to their high sensitivity and specificity. Several NAATs have been evaluated for testing in rectal and pharyngeal infections. A few assays recently received clearance by the Food and Drug Administration, including one point-of-care test. Those assays can be used for testing in symptomatic individuals, as well as for asymptomatic screening in certain patient populations. Routine screening for C. trachomatis in pharyngeal specimens is not recommended by the Centers for Disease Control and Prevention, though is often performed due to the use of multiplex assays. While expanding the types of settings for screening and using self-collected rectal and pharyngeal specimens can help to increase access and uptake of testing, additional research is needed to determine the potential benefits and costs associated with increased screening for rectal and pharyngeal C. trachomatis and N. gonorrhoeae infections on a population level.

Abstract
BACKGROUND Urogenital testing misses extragenital Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT). Extragenital self-sampling is frequently undertaken despite no robust randomized, controlled trial evidence of efficacy. We compared clinician-taken rectal and pharyngeal samples with self-taken samples for diagnostic accuracy and cost in men who have sex with men (MSM) and in females. METHODS This was a prospective convenience sample from a UK sexual health clinic. We randomized the order of clinician- and self-taken samples from the pharynx and rectum, plus first catch urine (MSM) and vulvovaginal swabs (females), for NG/CT detection. RESULTS Of 1793 participants (1284 females, 509 MSM), 116 had NG detected (75 urogenital, 83 rectum, 72 pharynx); 9.4% infected females and 67.3% MSM were urogenital-negative. A total of 276 had CT detected (217 urogenital, 249 rectum, 63 pharynx); 13.1% infected females and 71.8% MSM were urogenital-negative. Sexual history did not identify those with rectal infections. There was no difference in diagnostic accuracy between clinician- and self-taken samples from the rectum or pharynx. Clinicians took swabs more quickly than participants, so costs were lower. However, in asymptomatic people, nonqualified clinicians would oversee self-swabbing making these costs lower. CONCLUSIONS There was no difference in the diagnostic accuracy of clinician-taken compared with self-taken extragenital samples. Sexual history did not identify those with rectal infections, so individuals should have extragenital clinician- or self-taken samples. Clinician-taken swabs cost less than self-taken swabs; however, in asymptomatic people or those who perform home testing, the costs would be lower than for clinician-taken swabs.

Abstract
Background The COVID-19 pandemic illuminated the benefits of telemedicine. Self-collected specimens are a promising alternative to clinician-collected specimens when in-person testing is not feasible. In this study, we assessed the adequacy of self-collected pharyngeal and rectal specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae among individuals undergoing chlamydia and gonorrhea screening. Methods We used data from a large cohort study that included male and female adolescents between the ages of 12–24 years. We considered self-collected specimens adequate for clinical use if the human synthase gene (a control target of the assay) was detected in the specimen. Results In total, 2,458 specimens were included in the analysis. The human synthase gene was detected in 99.2% (2,439/2,458) of all self-collected specimens, 99.5% (1,108/1,114) of the pharyngeal specimens, and 99.0% (1,331/1,344) of the rectal specimens. Conclusion Self-collected pharyngeal and rectal specimens demonstrated a very high proportion of human gene presence, suggesting that self-collection was accurate. A limitation of this study is that the sample adequacy control detects the presence or absence of the human hydroxymethylbilane synthase gene, but it does not indicate the specific anatomic origin of the human hydroxymethylbilane synthase gene. Self-collected specimens may be an appropriate alternative to clinician-collected specimens.

Abstract
These guidelines for the treatment of persons who have or are at risk for
sexually transmitted infections (STIs) were updated by CDC after consultation
with professionals knowledgeable in the field of STIs who met in Atlanta,
Georgia, June 11–14, 2019. The information in this report updates the
2015 guidelines. These guidelines discuss 1) updated recommendations for
treatment of Neisseria gonorrhoeae, Chlamydia trachomatis,
and Trichomonas vaginalis; 2) addition of
metronidazole to the recommended treatment regimen for pelvic inflammatory
disease; 3) alternative treatment options for bacterial vaginosis; 4) management
of Mycoplasma genitalium; 5) human papillomavirus vaccine
recommendations and counseling messages; 6) expanded risk factors for syphilis
testing among pregnant women; 7) one-time testing for hepatitis C infection; 8)
evaluation of men who have sex with men after sexual assault; and 9) two-step
testing for serologic diagnosis of genital herpes simplex virus. Physicians and
other health care providers can use these guidelines to assist in prevention and
treatment of STIs.

Abstract
Self- or caregiver collection of upper airway swabs reduces infectious exposures of health care workers (HCWs) and the need to redeploy clinical staff to testing roles. We aimed to determine whether self- or caregiver collection has adequate diagnostic performance for detection of viral and bacterial upper airway pathogens. We did a systematic review and meta-analysis of studies comparing diagnostic accuracy of self- or caregiver-collected upper airway swabs collected by patients or caregivers compared to HCWs. All study types except case reports and series were included if sufficient data were presented to calculate sensitivity, specificity, and Cohen's kappa. Studies published from 1946 to 17 August 2020 were included in the search. We did a meta-analysis to assess pooled sensitivity and specificity. Twenty studies were included in the systematic review and 15 in the meta-analysis. The overall sensitivity of swabs collected by patients or caregivers compared to HCWs was 91% (95% confidence interval [CI], 87 to 94), and specificity was 98% (95% CI, 96 to 99). Sensitivity ranged from 65% to 100% and specificity from 73% to 100% across the studies. All but one study concluded that self- or caregiver-collected swabs were acceptable for detection of upper airway pathogens. Self- and caregiver collection of upper airway swabs had reassuring diagnostic performance for multiple pathogens. There are numerous potential benefits of self- and caregiver-collected swabs for patients, families, researchers, and health systems. Further research to optimize implementation of sample collection by patients and caregivers is warranted.

Abstract
BACKGROUND Rectal and oral Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) infections are common among people with HIV, especially men who have sex with men (MSM); however, GC/CT testing rates remain low in many HIV clinics. We evaluated the real-world implementation and results of extragenital nucleic acid amplification testing for GC/CT in an urban HIV clinic. METHODS Electronic health records were reviewed for all patients 18 years or older with ≥1 outpatient visit to an HIV clinic in Dallas, TX, from February 2016 to May 2019. Extragenital nucleic acid amplification testing became available in February 2017, which was followed by active interventions to increase testing. RESULTS Overall, 5564 individual patients were included in the preintervention period (February 2016-January 2017), 5067 in the intervention period (February 2017-August 2017), and 7030 in the postintervention period (September 2017-May 2018). Tailored education was provided to patients, and nursing and medical providers, and a self-collection protocol was implemented beginning in spring 2017. A sustained increase in extragenital GC/CT testing among MSM patients, from 70% to 87% (P < 0.01), was observed. Among MSM, overall GC positivity increased from 3.2% to 8.5% and CT positivity increased from 3.9% to 8.3%. N. gonorrhoeae/C. trachomatis infections were highest among young (<35 years) MSM, and approximately 50% of GC/CT infections diagnosed were detected by oral and rectal tests. CONCLUSIONS Clinic-wide education and self-collection of extragenital specimens were associated with increased GC/CT testing and detection in a large HIV clinic.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has led many clinics to move from clinician-collected to self-collected oropharyngeal swabs for the detection of sexually transmitted infections (STIs). Before this change, however, self-collection was used primarily for genital and anorectal infections, with only limited studies on the performance of self-collection of oropharyngeal swabs for oropharyngeal STI detection. The Melbourne Sexual Health Centre (MSHC) changed from clinician-collected to self-collected oropharyngeal swabs for oropharyngeal gonorrhea and chlamydia screening on 16 March 2020 in order to reduce health care worker risk during the COVID-19 pandemic. We compared the proportions of valid and positive samples for gonorrhea and chlamydia among men who have sex with men (MSM) in two time periods; the clinician collection period, between 20 January and 15 March 2020, and the self-collection period, between 16 March and 8 May 2020. A total of 4,097 oropharyngeal swabs were included. The proportion of oropharyngeal swabs with equivocal or invalid results for Neisseria gonorrhoeae was higher in the self-collection period (1.6% [24/1,497]) than in the clinician collection period (0.9% [23/2,600]) (P = 0.038), but the proportions did not differ for the detection of Chlamydia trachomatis The positivity rates of oropharyngeal N. gonorrhoeae (adjusted prevalence ratio [PR], 1.07 [95% confidence interval {CI}, 0.85 to 1.34]) (P = 0.583) and oropharyngeal C. trachomatis (adjusted PR, 0.84 [95% CI, 0.51 to 1.39]) (P = 0.504) specimens did not differ between the two periods. Self-collected oropharyngeal swabs for the detection of N. gonorrhoeae and C. trachomatis have acceptable performance characteristics and, importantly, reduce health care worker exposure to respiratory infections.

Abstract
OBJECTIVE The optimal screening frequency of sexually transmitted infections (STIs) for MSM and transgender women (TGW) on HIV pre-exposure prophylaxis (PrEP) is unclear, with present guidelines recommending screening every 3-6 months. We aimed to determine the number of STIs for which treatment would have been delayed without quarterly screening. DESIGN The US PrEP Demonstration Project was a prospective, open-label cohort study that evaluated PrEP delivery in STI clinics in San Francisco and Miami, and a community health center in Washington, DC. In all, 557 HIV-uninfected MSM and TGW were offered up to 48 weeks of PrEP and screened quarterly for STIs. METHODS The proportion of gonorrhea, chlamydia, and syphilis infections for which treatment would have been delayed had screening been conducted every 6 versus every 3 months was determined by taking the number of asymptomatic STIs at weeks 12 and 36 divided by the total number of infections during the study follow-up period for each STI. RESULTS Among the participants, 50.9% had an STI during follow-up. If screening had been conducted only semiannually or based on symptoms, identification of 34.3% of gonorrhea, 40.0% of chlamydia, and 20.4% of syphilis infections would have been delayed by up to 3 months. The vast majority of participants (89.2%) with asymptomatic STIs reported condomless anal sex and had a mean of 8.1 partners between quarterly visits. CONCLUSIONS Quarterly STI screening among MSM on PrEP could prevent a substantial number of partners from being exposed to asymptomatic STIs, and decrease transmission.

Abstract
PURPOSE OF REVIEW This study aims to review the epidemiology of sexually transmitted infections (STIs) among men who have sex with men (MSM) and suggest control measures. RECENT FINDINGS Despite declines in new HIV diagnosis, bacterial STIs among MSM have dramatically risen since the late 1990s. This increase occurred concurrent with introduction of effective antiretroviral therapy, the advent of electronic mechanisms for meeting sex partners and population-level changes in sexual behavior, including decreased condom use. HIV pre-exposure prophylaxis (PrEP) is now further diminishing condom use, though its impact on STIs is uncertain. A plan to confront the MSM STI epidemic should include increased HIV/STI testing promoted through expanded public health clinical infrastructure, health care system reform to improve the care of gender and sexual minorities and promote low-barrier care, re-invigorated condom promotion, and scientific innovation. There is an urgent need to implement new STI control measures while continuing to expand PrEP use.

Abstract
BACKGROUND Sexually transmitted infections (STIs) disproportionately affect men who have sex with men. Although clinical practice guidelines recommend routine STI screening of men who have sex with men who have high-risk behaviors, extragenital STI testing rates have been low in HIV clinics across the nation. The University of Washington STD Prevention Training Center implemented an STI self-testing program at a large HIV primary care clinic in Seattle, WA, to facilitate extragenital STI testing. METHODS We performed a mixed-methods program evaluation to assess health care provider acceptability of the program at 9 months after implementation. Twenty-eight clinicians were invited to complete an online survey. We conducted one-on-one, semistructured interviews with 6 clinicians and a focus group with 7 members of the clinic nursing staff. Survey responses were tallied. Conventional content analysis was performed on survey comments and transcripts from the interviews and focus group. RESULTS Ninety-one percent of clinicians were either satisfied or very satisfied with the program. Perceived advantages of the program included saving time for clinicians, overcoming patient discomfort, and increasing patient access to testing. Perceived program disadvantages included unclear responsibility of directing patients through the self-testing process and incorrect sample collection and labeling. CONCLUSIONS Despite perceived disadvantages, the self-testing program was acceptable to clinicians and nursing staff, key population for successful program adoption. Implementation of STI self-testing programs in clinic settings could help to increase extragenital STI testing rates by removing provider and patient barriers to testing.

Abstract
OBJECTIVES To inform the development of targeted sexually transmitted infection (STI) control programmes for persons who inject drugs (PWID). METHODS We recruited 116 PWID (aged ≥ 18 years) from a community-based syringe exchange programme (SEP) and assessed their STI knowledge and screening preferences via technology assisted self-interview. We estimated prevalence of STI transmission knowledge, attitudes and screening preferences as well as the association between reported sexual behaviours (past 6 months) and willingness to self-collect specimens. RESULTS Participants were white (77%), female (51%) and heterosexual (77%). STI knowledge regarding transmission and testing was high among the sample. More than 70% of participants were aware extragenital infections were possible and were least likely to know urine tests do not detect rectal infections (40.9%). Site-specific specimen collection was highly reflective of reported sexual behaviour. PWID who reported receptive sex (36% vs 5%, p<0.01) and insertive anal sex (31% vs 6%, p=0.01) were more likely to collect rectal specimens than those who did not. A similar trend was seen for oral sex performance on men and self-collection of oropharyngeal swabs (15% vs 3%, p=0.04). In addition, participants preferred collecting their own sample to having a clinician collect it for them (69% vs 31%, p<0.01) and testing at the SEP compared with a STI clinic (86% vs 14%, p<0.01). CONCLUSION Our findings suggest site-specific specimen collection may be a proxy for risk behaviour engagement in this fairly knowledgeable high-risk population. To increase case finding, STI control programmes should educate patients about site-specific screening and pair outreach with the infrastructure provided by SEPs, in settings where these programmes exist.

Yang TZT, Chen MY, Read TRH, Needleman R, Bradshaw CS, Fortune R, Fairley CK, Chow EPF. Sampling technique and detection rates of oropharyngeal and anorectal gonorrhoea using nucleic acid amplification tests in men who have sex with men. Sex Transm Infect 2017; 94:287-292. [PMID: 29133523 DOI: 10.1136/sextrans-2017-053339] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Revised: 10/18/2017] [Accepted: 10/21/2017] [Indexed: 11/03/2022] Open
Abstract
OBJECTIVES The objective of this study was to examine the associations between clinicians' self-reported sampling technique and the detection rate of gonorrhoea at the oropharynx and anorectum using a highly sensitive nucleic acid amplification test (NAAT). METHODS We analysed oropharyngeal and anorectal gonorrhoea swab results among men who have sex with men attending the Melbourne Sexual Health Centre (MSHC) between March 2015 and December 2016. Swabs were tested by NAAT using the Aptima Combo 2 transcription-mediated amplification assay due to its high sensitivity. Clinicians at MSHC were invited to complete a questionnaire on sampling techniques in November 2016. Univariable generalised estimating equations (GEE) logistic regressions were performed to determine the association between gonorrhoea detection rates and clinicians' sampling technique. Patients' epidemiological risk factors were included in the multivariable GEE logistic model. RESULTS A total of 2605 oropharyngeal gonorrhoea and 2392 anorectal gonorrhoea swab results were analysed. There was no significant difference in the detection rates of gonorrhoea between the 23 clinicians at the oropharynx (range 3.6%-16.9%, median 8.2%, P=0.302) or and anorectum (range 2.4%-17.3%, median 10.5%, P=0.177). Variations in clinicians' self-reported sampling technique were not associated with oropharyngeal or anorectal gonorrhoea detection rates after adjusting for patients' epidemiological risk factors. CONCLUSIONS This study shows that differences in clinicians' self-reported sampling technique did not result in measurable differences in the detection rate for oropharyngeal or anorectal gonorrhoea when using NAAT.

The Case for Extragenital Screening of Chlamydia trachomatis and Neisseria gonorrhoeae in the College Health Setting. Sex Transm Dis 2017; 44:274-277. [PMID: 28407642 DOI: 10.1097/olq.0000000000000593] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Although the Centers for Disease Control and Prevention does not recommend routine oropharyngeal and anorectal screening for Chlamydia trachomatis and Neisseria gonorrhoeae in the general population, they do recommend it for men who have sex with men. However, risk-based extragenital screening of men may not have been adopted at all college health centers, and existing research has not focused on the college population. METHODS We examined health records of men at a college health center in a large urban university over 6 years to evaluate effectiveness of C. trachomatis and N. gonorrhoeae screening. We also evaluated the proportion of C. trachomatis and N. gonorrhoeae infections that would have been missed if risk-based extragenital screening were not performed. Decisions to screen at extragenital sites were based on patient-reported risk behavior. RESULTS For 4093 male college students screened, 7.6% of the screening visits used extragenital screening in response to self-reported risk behaviors. The case positivity rate for C. trachomatis was 3.1% with urogenital-only screening and 3.7% with risk-prompted extragenital screening. The case positivity rate for N. gonorrhoeae was 0.7% with urogenital-only screening and 3.3% with risk-prompted extragenital screening. If the college health center had relied solely on urogenital screening rather than risk-based extragenital screening, 26.4% of C. trachomatis infections and 63.2% of N. gonorrhoeae infections would have been missed. CONCLUSIONS One out of four C. trachomatis infections and 2 of 3 N. gonorrhoeae infections would have been missed without extragenital screening in this analysis of college men. This study reinforces Centers for Disease Control and Prevention recommendations for risk-based extragenital screening and is the first report to focus on college men. Because guidelines exist only for men, future studies should focus on extragenital screening in college women to build evidence for another group of patients that may benefit from this practice, given the high risk in young adults.

Abstract
BACKGROUND Rates of screening for bacterial sexually transmitted infections (STI) among men who have sex with men in HIV care settings remain low despite high prevalence of these infections. STI self-testing may help increase screening rates in clinical settings. METHODS We implemented an STI self-testing program at a large, urban HIV care clinic and evaluated its effectiveness and acceptability. We compared measures obtained during the first year of the STI self-testing program (Intervention Year, April 1, 2013-March 31, 2014) to Baseline Year (January 1, 2012-December 31, 2012) to determine: (1) overall clinic change in STI testing coverage and diagnostic yield and; (2) program-specific outcomes including appropriate anatomic site screening and patient-reported acceptability. RESULTS Overall, testing for gonorrhea and chlamydia increased significantly between Baseline and Intervention Year, and 50% more gonococcal and 47% more chlamydial infections were detected. Syphilis testing coverage remained unchanged. Nearly 95% of 350 men who participated in the STI self-testing program completed site-specific testing appropriately based on self-reported exposures, and 92% rated their self-testing experience as "good" or "very good." CONCLUSIONS STI self-testing in HIV care settings significantly increases testing coverage and detection of gonorrhea and chlamydia, and the program is acceptable to patients. Additional interventions to increase syphilis screening rates are needed.

Abstract
The past 3 years have marked a transition from research establishing the safety and efficacy of HIV preexposure prophylaxis (PrEP) to questions about how to optimize its implementation. Until recently, PrEP was primarily offered as part of randomized controlled trials or open-label studies. These studies highlighted the key components of PrEP delivery, including regular testing for HIV and other sexually transmitted infections (STIs), adherence and risk-reduction support, and monitoring for renal toxicity. PrEP is now increasingly provided in routine clinical settings. This review summarizes models for PrEP implementation from screening through initiation and follow-up, focusing on the strengths and weaknesses of three delivery systems: a health maintenance organization, an STI clinic, and a primary care practice. These early implementation experiences demonstrate that PrEP can be successfully delivered across a variety of settings and highlight strategies to streamline PrEP delivery in clinical practice.

Abstract
In preparation for the 2015 Centers for Disease Control and Prevention (CDC) Sexually Transmitted Diseases (STD) Treatment Guidelines, the CDC convened an advisory group in 2013 to examine recent abstracts and published literature addressing the epidemiology, diagnosis, and management of STDs. This article summarizes the key questions, evidence, and recommendations for the diagnosis and management of uncomplicated Chlamydia trachomatis (CT) infection in adolescents and adults that were considered in development of the 2015 CDC STD Treatment Guidelines. The evidence reviewed primarily focused on CT infection risk factors in women, clinical significance of oropharyngeal CT detection, acceptability and performance of CT testing on self-collected specimens in men, performance of CT point-of-care tests, efficacy of recommended and investigational CT infection treatments, and timing of test of cure following CT infection treatment in pregnant women.

Abstract
OBJECTIVE We investigated gay and bisexual men's willingness to self-administer an anal cancer screening test at home. METHODS We conducted 2 national, online cross-sectional surveys of self-identified gay and bisexual men: Study I in 2009 with men ages 20 to 59 (n = 306) and Study II in 2013 with men ages 18 to 26 (n = 428). We used multivariate logistic regression analyses to determine variables associated with willingness to self-administer the screening test. RESULTS Most men were willing to self-administer an anal cancer screening test (78% Study I; 67% Study II). In Study I, willingness was higher among men who trusted anal Paps to find treatable cancer (adjusted odds ratio [aOR] = 1.47; 95% CI, 1.04-2.09) and who believed that men who have sex with men should be screened for anal cancer between 1 and 3 years vs. other intervals (aOR = 2.19; 95% CI, 1.17-4.10). In Study II, willingness was higher among men who perceived greater likelihood of anal cancer (aOR = 1.57; 95% CI, 1.12-2.20). Their most common concerns were not performing the test correctly and inaccuracy of results. CONCLUSIONS Many gay and bisexual men were willing to self-administer anal cancer screening tests at home. If routine screening is warranted, self-collected home testing could improve participation.

Abstract
In the United States, sexually transmitted diseases due to Chlamydia trachomatis and Neisseria gonorrhoeae continue to be a major public health burden. Screening of extragenital sites including the oropharynx and rectum is an emerging practice based on recent studies highlighting the prevalence of infection at these sites. We reviewed studies reporting the prevalence of extragenital infections in women, men who have sex with men (MSM), and men who have sex only with women (MSW), including distribution by anatomical site. Among women, prevalence was found to be 0.6–35.8% for rectal gonorrhea (median reported prevalence 1.9%), 0–29.6% for pharyngeal gonorrhea (median 2.1%), 2.0–77.3% for rectal chlamydia (median 8.7%), and 0.2–3.2% for pharyngeal chlamydia (median 1.7%). Among MSM, prevalence was found to be 0.2–24.0% for rectal gonorrhea (median 5.9%), 0.5–16.5% for pharyngeal gonorrhea (median 4.6%), 2.1–23.0% for rectal chlamydia (median 8.9%), and 0–3.6% for pharyngeal chlamydia (median 1.7%). Among MSW, the prevalence was found to be 0–5.7% for rectal gonorrhea (median 3.4%), 0.4–15.5% for pharyngeal gonorrhea (median 2.2%), 0–11.8% for rectal chlamydia (median 7.7%), and 0–22.0% for pharyngeal chlamydia (median 1.6%). Extragenital infections are often asymptomatic and found in the absence of reported risk behaviors, such as receptive anal and oral intercourse. We discuss current clinical recommendations and future directions for research.

Abstract
OBJECTIVES This study aimed to characterise the epidemiology of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections among men who have sex with men (MSM) and transgender women (TW) in Lima, Peru. SETTING Cross-sectional study in Lima, Peru. PARTICIPANTS We recruited a group of 510 MSM and 208 TW for a subsequent community-based randomised controlled trial. The presence of CT and NG were evaluated using Aptima Combo2 in pharyngeal and anal swabs. We also explored correlates of these infections. PRIMARY AND SECONDARY OUTCOME MEASURES Study end points included overall prevalence of C. trachomatis and N. gonorrhoeae in anal and pharyngeal sites. RESULTS Overall prevalence of CT was 19% (95% CI 16.1% to 22.1%) and 4.8% (95% CI 3.3% to 6.6%) in anal and pharyngeal sites, respectively, while prevalence of NG was 9.6% (95% CI 7.5% to 12.0%) and 6.5% (95% CI 4.8% to 8.5%) in anal and pharyngeal sites, respectively. CONCLUSIONS The prevalence of each infection declined significantly among participants older than 34 years (p<0.05). Efforts towards prevention and treatment of extraurogenital chlamydial and gonococcal infections in high-risk populations like MSM and TW in Lima, Peru, are warranted.

Self-Collected versus Clinician-Collected Sampling for Chlamydia and Gonorrhea Screening: A Systemic Review and Meta-Analysis. PLoS One 2015; 10:e0132776.

Abstract
BACKGROUND The increases in STI rates since the late 1990s in Canada have occurred despite widespread primary care and targeted public health programs and in the setting of universal health care. More innovative interventions are required that would eliminate barriers to STI testing such as internet-based or mail-in home and community service testing for patients that are hard to reach, who refuse to go for clinician-based testing, or who decline an examination. Jurisdictions such as New Zealand and some American states currently use self-collected sampling, but without the required evidence to determine whether self-collected specimens are as accurate as clinician-collected specimens in terms of chlamydia and gonorrhea diagnostic accuracy. The objective of the review is to compare self-collected vaginal, urine, pharyngeal and rectal samples to our reference standard - clinician-collected cervical, urethral, pharyngeal and rectal sampling techniques to identify a positive specimen using nucleic acid amplification test assays. METHODS The hierarchical summary receiver operating characteristic and the fixed effect models were used to assess the accuracy of comparable specimens that were collected by patients compared to clinicians. Sensitivity and specificity estimates with 95% confidence intervals (CI) were reported as our main outcome measures. FINDINGS We included 21 studies based on over 6100 paired samples. Fourteen included studies examined chlamydia only, 6 compared both gonorrhea and chlamydia separately in the same study, and one examined gonorrhea. The six chlamydia studies comparing self-collection by vaginal swab to a clinician-collected cervical swab had the highest sensitivity (92%, 95% CI 87-95) and specificity (98%, 95% CI 97-99), compared to other specimen-types (urine/urethra or urine/cervix). Six studies compared urine self-samples to urethra clinician-collected samples in males and produced a sensitivity of 88% (95% CI 83-93) and a specificity of 99% (95% CI 0.94-0.99). Taking into account that urine samples may be less sensitive than cervical samples, eight chlamydia studies that compared urine self-collected verses clinician-collected cervical samples had a sensitivity of 87% (95% CI 81-91) and high specificity of 99% (95% CI 0.98-1.00). For gonorrhea testing, self-collected urine samples compared to clinician-collected urethra samples in males produced a sensitivity of 92% (95% CI 83-97) and specificity of 99% (95% CI 0.98-1.00). CONCLUSION The sensitivity and specificity of vaginal self-collected swabs compared to swabs collected by clinicians supports the use of vaginal swab as the recommended specimen of choice in home-based screening for chlamydia and gonorrhea. Urine samples for gonorrhea collected by men had comparably high sensitivity and specificity, so could be recommended as they can be left at room temperature for several days, allowing for the possibility of mail-in home-based testing. In populations that may not go for testing at all, do not have the option of clinical testing, or who refuse a clinical examination, self-collected screening would be a good alternative. We recommend that guidelines on how to self-collect gonorrhea and chlamydia urine, vaginal, rectal and pharyngeal specimens be published.

Abstract
Background Routine screening is key to sexually transmitted infection (STI) prevention and control. Previous studies suggest that clinic-based screening programmes capture only a small proportion of people with STIs. Self-sampling using non- or minimally invasive techniques may be beneficial for those reluctant to actively engage with conventional sampling methods. We systematically reviewed studies of patients’ experiences of obtaining self-samples to diagnose curable STIs. Methods We conducted an electronic search of MEDLINE, EMBASE, CINAHL, PsychINFO, BNI, and Cochrane Database of Systematic Reviews to identify relevant articles published in English between January 1980 and March 2014. Studies were included if participants self-sampled for the diagnosis of a curable STI and had specifically sought participants’ opinions of their experience, acceptability, preferences, or willingness to self-sample. Results The initial search yielded 558 references. Of these, 45 studies met the inclusion criteria. Thirty-six studies assessed patients’ acceptability and experiences of self-sampling. Pooled results from these studies shows that self-sampling is a highly acceptable method with 85% of patients reporting the method to be well received and acceptable. Twenty-eight studies reported on ease of self-sampling; the majority of patients (88%) in these studies found self-sampling an “easy” procedure. Self-sampling was favoured compared to clinician sampling, and home sampling was preferred to clinic-based sampling. Females and older participants were more accepting of self-sampling. Only a small minority of participants (13%) reported pain during self-sampling. Participants were willing to undergo self-sampling and recommend others. Privacy and safety were the most common concerns. Conclusion Self-sampling for diagnostic testing is well accepted with the majority having a positive experience and willingness to use again. Standardization of self-sampling procedures and rigorous validation of outcome measurement will lead to better comparability across studies. Future studies need to conduct rigorous economic evaluations of self-sampling to inform policy development for the management of STI.

Effect of nucleic acid amplification testing on detection of extragenital gonorrhea and chlamydial infections in men who have sex with men sexually transmitted disease clinic patients. Sex Transm Dis 2014; 41:168-72.

Abstract
BACKGROUND In 2010, the Centers for Disease and Control and Prevention recommended using nucleic acid amplification tests (NAATs) for extragenital gonorrhea (GC) and chlamydia (CT) testing because of NAATs' improved sensitivity compared with culture. METHODS In 2011, the Public Health-Seattle & King County Sexually Transmitted Disease Clinic introduced NAAT-based testing for extragenital GC and CT infection in men who have sex with men (MSM) using AptimaCombo2. We compared extragenital GC and CT test positivity and infection detection yields in the last year of culture-based testing (2010) to the first year of NAAT testing (2011). RESULTS Test positivity of GC increased by 8% for rectal infections (9.0%-9.7%) and 12% for pharyngeal infections (5.8%-6.5%) from 2010 to 2011; CT test positivity increased 61% for rectal infections (7.4%-11.9%). Pharyngeal CT was identified in 2.3% of tested persons in 2011 (not tested in 2010). We calculated the ratio of extragenital cases per 100 urethral infections to adjust for a possible decline in GC/CT incidence in 2011; the GC rectal and pharyngeal ratios increased 77% and 66%, respectively, and the CT rectal ratio increased 127%. The proportion of infected persons with isolated extragenital infections (i.e., extragenital infections without urethral infection) increased from 43% in 2010 to 57% in 2011. CONCLUSIONS Extragenital testing with NAAT substantially increases the number of infected MSM identified with GC or CT infection and should continue to be promoted.

Abstract
OBJECTIVES We describe and report findings from a screening program to identify sexually transmitted infections (STIs) and HIV among female inmates in Los Angeles County Jail. METHODS Chlamydia and gonorrhea screening was offered to entering female inmates. Women were eligible if they were (1) aged 30 years or younger, or (2) pregnant or possibly pregnant, or (3) booked on prostitution or sex-related charges. Voluntary syphilis and HIV testing was offered to all women between 2006 and 2009. This analysis reports on data collected from 2002 through 2012. RESULTS A total of 76,207 women participated in the program. Chlamydia prevalence was 11.4% and gonorrhea was 3.1%. Early syphilis was identified in 1.4% (141 of 9733) and the overall prevalence of HIV was 1.1% (83 of 7448). Treatment levels for early syphilis and HIV were high (99% and 100%, respectively), but only 56% of chlamydia and 58% of gonorrhea cases were treated. CONCLUSIONS Screening incarcerated women in Los Angeles County revealed a high prevalence of STIs and HIV. These inmates represent a unique opportunity for the identification of STIs and HIV, although strategies to improve chlamydia and gonorrhea treatment rates are needed.

Abstract
Summary To manage the rising demand on sexual health services in the UK, many clinics have introduced asymptomatic screening pathways for heterosexuals, which omit examination. In men who have sex with men however the screening of extragenital sites poses additional challenges. This study aimed to establish whether omitting examination of asymptomatic men who have sex with men would lead to clinically significant diagnoses being missed. The notes of all men who have sex with men who attended a UK level 3 sexual health clinic between 1 July 2011 and 30 June 2012 were retrospectively reviewed. Exclusion criteria included HIV-positive patients attending for HIV-related care, attendances for follow-up consultations not requiring a full sexual health screen, symptomatic patients, contacts of sexually transmitted infections and patients requesting an examination or a repeat prescription of a regularly used medication. In all, 920 consultations occurred during 12 months, of which 893 were reviewed; 476 (53.3%) consultations would have been eligible for screening on an asymptomatic pathway and, of these, 21 (4.4%) had abnormalities found at examination. Findings included genital warts, minor dermatological conditions and three cases of minor asymptomatic urological conditions. There were no clinically significant findings on examination of asymptomatic men who have sex with men requiring treatment, indicating that examination in this cohort may be of little benefit.

Abstract
BACKGROUND Gonorrhea (GC) and chlamydia (CT) are the most commonly reported notifiable diseases in the United States. The Centers for Disease Control and Prevention recommends that men who have sex with men (MSM) be screened for urogenital GC/CT, rectal GC/CT, and pharyngeal GC. We describe extragenital GC/CT testing and infections among MSM attending sexually transmitted disease (STD) clinics. METHODS The STD Surveillance Network collects patient data from 42 STD clinics. We assessed the proportion of MSM attending these clinics during July 2011-June 2012 who were tested and positive for extragenital GC/CT at their most recent visit or in the preceding 12 months and the number of extragenital infections that would have remained undetected with urethral screening alone. RESULTS Of 21 994 MSM, 83.9% were tested for urogenital GC, 65.9% for pharyngeal GC, 50.4% for rectal GC, 81.4% for urogenital CT, 31.7% for pharyngeal CT, and 45.9% for rectal CT. Of MSM tested, 11.1% tested positive for urogenital GC, 7.9% for pharyngeal GC, 10.2% for rectal GC, 8.4% for urogenital CT, 2.9% for pharyngeal CT, and 14.1% for rectal CT. More than 70% of extragenital GC infections and 85% of extragenital CT infections were associated with negative urethral tests at the same visit and would not have been detected with urethral screening alone. CONCLUSIONS Extragenital GC/CT was common among MSM attending STD clinics, but many MSM were not tested. Most extragenital infections would not have been identified, and likely would have remained untreated, with urethral screening alone. Efforts are needed to facilitate implementation of extragenital GC/CT screening recommendations for MSM.

Abstract
Neisseria gonorrhoeae has developed resistance to all previous first-line antimicrobial therapies over the past 75 years. Today the cephalosporins, the last available antibiotic class that is sufficiently effective, are also threatened by evolving resistance. Screening for asymptomatic gonorrhea in women and men who have sex with men, treating with a dual antibiotic regimen, ensuring effective partner therapy, and remaining vigilant for treatment failures constitute critical activities for clinicians in responding to evolving antimicrobial resistance. This article reviews the epidemiology, history of antimicrobial resistance, current screening and treatment guidelines, and future treatment options for gonorrhea.

Abstract
Chlamydial genital infection is common and asymptomatic in most cases. National screening efforts developed to educate practitioners, expand screening, and link testing to local health laboratories are not meeting the needs of populations at great risk of disease, including young racial/ethnic minority women and sexual minorities. The development and availability of newer diagnostics will likely make chlamydia testing more efficient and widely available for patients and providers. Practitioners are reminded to have a low threshold to offer testing and presumptive treatment to patients that are deemed at high risk of disease, particularly those who are challenging to engage in care.

Abstract
Chlamydia is the most commonly diagnosed bacterial sexually transmitted infection in the developed world, with diagnosis rates continuing to increase each year. As chlamydia is largely asymptomatic, screening and treatment is the main way to detect cases and reduce transmission. Recent advances in self-collected specimens and laboratory tests has made chlamydia screening easier to implement as well as possible in nonclinical settings. This review will discuss new approaches to specimen collection and how these have expanded opportunities for reaching target populations for chlamydia screening. Furthermore, it will discuss how advanced molecular microbiological methods can be used with self-collected specimens to further our knowledge of the epidemiology of chlamydia and the dynamics of transmission.

Abstract
The prevalence of pharyngeal gonorrhoea in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) is not entirely known. We cultured the pharynx of 264 asymptomatic HIV-positive MSM in downtown Madrid. A questionnaire on sexual and drug use risk behaviours was also administered. Gonococci were isolated in 25 (9.5%). Among the whole study population, 65% had a history of sexual intercourse with two or more partners on a single day and 26% were involved in group sex with other men. Only 29% regularly used condoms in all sexual encounters and 63% used condoms only in insertive anal intercourse. When asked about oral sex, 89% of patients engaged in insertive and/or receptive oral sex and 86% recognized that they did not regularly request the use of condoms when practising “ fellatio” on a partner. Cocaine, crystal methamphetamine or alcohol use and a previous history of ≥1 sexually transmitted infection were significantly more common among culture-positive patients. Gonococcal colonization of the pharynx was self-limited in patients that were not treated and re-cultured a mean 18.5 ± 5.2 days after diagnosis. Asymptomatic pharyngeal gonorrhoea is common among HIV-positive MSM and may contribute to the increasing epidemic of gonorrhoea in Madrid.

Abstract
Background Studies frequently use nasal swabs to determine Staphylococcus aureus carriage. Self-sampling would be extremely useful in an outhospital research situation, but has not been studied in a healthy population. We studied the similarity of self-samples and investigator-samples in nares and pharynxes of healthy study subjects (hospital staff) in the Netherlands. Methods One hundred and five nursing personnel members were sampled 4 times in random order after viewing an instruction paper: 1) nasal self-sample, 2) pharyngeal self-sample, 3) nasal investigator-sample, and 4) pharyngeal investigator-sample. Results For nasal samples, agreement is 93% with a kappa coefficient of 0.85 (95% CI 0.74-0.96), indicating excellent agreement, for pharyngeal samples agreement is 83% and the kappa coefficient is 0.60 (95% CI 0.43-0.76), indicating good agreement. In both sampling sites self-samples even detected more S. aureus than investigator-samples. Conclusions This means that self-samples are appropriate for detection of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus.
