Abstract
The last literature review on swingers was written by Richard J. Jenks in 1998, and for the past 25 years, no review has been published with a focus solely this group. Some individual studies have analysed swinging together with other consensual non-monogamies, while other research has looked at swinging in the context of sexual health. This paper presents early and recent literature on swinging, highlighting some of the directions taken in swinger research, and addressing the challenges of finding a theoretical framework suitable to explain swingers, swinger settings, and swinging.

Cachay ER, Gilbert T, Deiss R, Mathews WC. Shared Decision-Making Concerning Anal Cancer Screening in Persons With Human Immunodeficiency Virus. Clin Infect Dis 2023; 76:582-591. [PMID: 35723270 PMCID: PMC10226749 DOI: 10.1093/cid/ciac491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/31/2022] [Accepted: 06/09/2022] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Anal high-grade squamous intraepithelial lesion (aHSIL) is the immediate precursor of anal cancer. Anal cytology is a recommended screening test to identify aHSIL among people with human immunodeficiency virus (HIV; PWH). Heterogeneity of risk for invasive anal cancer among PWH suggests the value of a shared decision-making framework regarding screening. METHODS Using a longitudinal HIV cohort with a comprehensive anal cancer screening program, we estimated the adjusted probabilities of having aHSIL on the first anal cytology. We used logistic regression models with inverse probability weighting to account for differential screening in the cohort and to construct a predicted probability nomogram for aHSIL. Sensitivity analysis was performed to estimate aHSIL prevalence corrected for misclassification bias. RESULTS Of 8139 PWH under care between 2007 and 2020, 4105 (49.8%) underwent at least 1 anal cytology test. First-time cytology aHSIL was present in 502 (12.2%) PWH. The adjusted probability of having aHSIL varied from 5% to 18% depending on patient characteristics. Prespecified factors in the aHSIL prediction model included nadir CD4 cell count, ethnicity, race, age, sex, gender identity, and HIV risk factors. The ability of the model to discriminate cytological aHSIL was modest, with an area under the curve of 0.63 (95% confidence interval, .60-.65). CONCLUSIONS PWH are at increased risk for aHSIL and invasive anal cancer. Risk, however, varies by patient characteristics. Individual risk factor profiles predictive of aHSIL can be modeled and operationalized as nomograms to facilitate shared decision-making conversations concerning anal cancer screening.

High proportions of rectal and pharyngeal chlamydia and gonorrhoea cases among cisgender men are missed using current CDC screening recommendations. Sex Transm Infect 2022; 98:586-591. [PMID: 35217590 PMCID: PMC9402804 DOI: 10.1136/sextrans-2021-055361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Accepted: 02/06/2022] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVES Pharyngeal and rectal Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections are often undiagnosed due to their asymptomatic nature. This study aims to determine (1) the prevalence of CT/NG infections by anatomical site among cisgender men; (2) the proportion of missed CT/NG rectal/pharyngeal infections if urogenital testing alone was performed or screening depended on self-reported behaviour alone; and (3) the predictive probability of self-reported behaviours for rectal CT/NG. METHODS This cross-sectional study used electronic health records collected at a sexual health clinic in Los Angeles from 18 November 2018 until 28 February 2020. The included patients were ≥18 years of age cisgender men who received CT/NG testing at least once during the study period. We calculated the proportion of missed pharyngeal/rectal CT/NG infections if only urogenital testing had been done and if testing was based only on self-reported anal sex. Separately, we ran logistic regressions for predictive probability of self-reported anal sex on CT/NG rectal infections. RESULTS Overall, there were 13 476 unique patients with 26 579 visits. The prevalence of any extragenital CT/NG infection was 37.28%. Over 80% rectal/pharyngeal CT cases and over 65% rectal/pharyngeal NG cases would be missed if urogenital testing alone was performed. Likewise, over 35% rectal CT/NG cases would be missed had testing relied on self-reported sexual behaviours alone. CONCLUSIONS The proportion of missed rectal and pharyngeal CT/NG infections is high. Our data from a sexual health clinic lend support to three-site opt-out testing for cisgender men attending a sexual health/Lesbian, Gay, Bisexual, Transgender, Queer/Questioning (LGBTQ+) specialty clinic regardless of their sexual orientation or reported sexual behaviours.

Abstract
Current research has suggested that sex, sexual practices and sexual identities are increasingly being folded into people’s leisure and recreational activities. One area that has witnessed growing popularity has been sex clubs that market themselves as places that enable heterosexual casual, anonymous sexual encounters. Traditionally called swingers’ clubs, these are not strip clubs, lap dancing clubs or brothels, we have very little information about sex clubs or the people who visit them. In response, this article defines what sex clubs are, their geographical locations, and their facilities. Alongside this, through the data scraping of 6837 profiles of people who have visited clubs and left online reviews of the clubs that they have visited, this research provides the most extensive dataset available on the gender, age, relationship status and sexual preferences of sex club patrons. The findings from the study suggest that sex clubs are an emerging space for leisure sex that prioritises erotic practices that stand outside heteronormative norms and values. Whilst clubs have been traditionally associated with swinger communities, the findings in this article also suggest that sex clubs appeal to people with diverse sexual preferences. Alongside this, it highlights the potential ways in which sex clubs may be part of a broader spatialization of leisure sex. The article concludes by suggesting that in a post-Covid context, sex clubs will have increasing importance as places of leisure sex.

Abstract
OBJECTIVES Neisseria gonorrhoeae infection of the anorectal tract is often asymptomatic and infrequently biopsied, but pathologists can be tasked with identifying the histologic features of possible infection. The study was undertaken to better characterize clinical and morphologic features of confirmed anorectal gonococcal infection. METHODS From 2011 to 2020, 201 positive gonococcal nucleic acid amplification testing samples from 174 patients collected from the distal colorectum and/or anus were matched to eight patients with concurrent biopsy specimens of the distal anorectum. Complete demographic, clinical, and infectious information was collected for each biopsied patient. The histomorphologic features of each biopsy were systematically tabulated. RESULTS All eight gonococcal cases were obtained from men who have sex with men. Each case showed at least mild acute inflammation with moderate activity identified in one case with concurrent cytomegalovirus infection. Intense lymphoplasmacytic infiltration was not commonly seen (two of eight). Half of the cases showed mucosal ulceration, and seven of eight cases demonstrated lymphoid aggregates. CONCLUSIONS The microscopic features are mild compared with other well-described types of infectious proctitis, with most cases displaying mild acute inflammation and scattered lymphoid aggregates. These findings highlight the importance of obtaining a complete patient history and recommending additional infectious workup even when only subtle changes are present.

Abstract
BACKGROUND This study aimed to determine the overall incidence and reinfection rates of sexually transmitted infections (STIs) and the discrepancy between self-reported exposure history and anatomic site positivity of STIs among adolescents and young adults (AYAs) with HIV in Atlanta, GA. METHODS Retrospective chart review was conducted on all patients 13-24 years of age at the Grady Ponce and Family Youth Clinic from January 1, 2009 to December 31, 2018. Data were collected on patient demographics, self-reported sexual history and STI events. First STI incidence and incidence of reinfections were calculated by dividing new cases over corresponding person follow-up time. RESULTS A total of 626 sexually active AYAs with HIV were included in analysis. The mean age at first observation was 18.9 (SD: ±2.8) years; 72% were male, 92% were Black and 80% were horizontally infected. The cumulative first STI incidence rate was 45.49 cases per 100 person-years, and the recurrent STI incidence rate was 119.86 cases per 100 person-years. Among all Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) cases, the most common site of infection was the rectum (48.6% and 49.6%, respectively). Disagreement between exposure history and presence of GC or CT infection was statistically significant for nearly all anatomic sites and types of intercourse. CONCLUSIONS AYAs with HIV in Atlanta have disproportionately high first and recurrent incidence rates of STIs, with many patients not reporting exposure at their site of infection. There is considerable need to increase screening for STIs, including routine extragenital testing for GC and CT, among AYAs with HIV regardless of self-reported exposure history.

Abstract
PURPOSE OF REVIEW Rectal chlamydia is a prevalent sexually transmissible infection in both men who have sex with men (MSM) and in women. Screening is recommended for MSM but remains controversial for women. The optimal treatment for rectal chlamydia is now conclusive but interpreting and managing positive results remains challenging. Infections among MSM are increasing and strategies are needed to reduce incident infections. This review summarizes recent developments for the screening and management of rectal chlamydia and its implications on reinfection. RECENT FINDINGS Reinfections in MSM may be occurring due to resumption of sex soon after treatment whereas repeat infections in women may occur due to autoinoculation in the absence of sex. Doxycycline is now first-line treatment but its role in chemoprophylaxis remains unclear. False positive results remain an issue, but the development of viability assays may prove useful in future to determine true infections. SUMMARY Doxycycline is the first-line treatment for rectal chlamydia and in women may prevent infections at the urogenital site. Viability assays can help to reduce antibiotic use once developed. The role of routine screening of rectal chlamydia in women remains unclear and this debate may soon include asymptomatic infections in MSM.

Abstract
BACKGROUND Although chlamydia (CT) and gonorrhea (GC) infections are increasing in the United States, there are limited data on their incidence, testing rates, and associated risk factors among persons living with HIV (PLWH), including by anatomic site among men who have sex with men (MSM). METHODS We analyzed 2007-2017 medical records data from Human Immunodeficiency Virus (HIV) Outpatient Study (HOPS) participants in care at 9 HIV clinics. We calculated CT (and GC) incidence and testing rates and assessed associations with sociodemographic and clinical factors using log-linear regression. RESULTS Among 4727 PLWH, 397 had 881 CT infections and 331 had 861 GC infections, with an incidence of 2.95 and 2.88 per 100 person-years, respectively. From 2007 to 2017, incidence and testing rates increased by approximately 3.0- and 1.9-fold for CT and GC, respectively. Multivariable factors associated with incident CT (GC) included younger age, MSM, and prior diagnoses of sexually transmitted diseases (STDs). Among 1159 MSM, 583 (50.3%) had 844 CT and 843 GC tests during 2016-2017, and 26.6% of tests were 3-site (urethra, rectum, and pharynx), yielding the highest rates of CT (GC) detection. Multivariable factors associated with CT (GC) testing included younger age, non-Hispanic/Latino black race, and having prior STDs. CONCLUSIONS Recent CT and GC incidence and testing increased among PLWH; however, only half of MSM were tested for CT or GC during 2016-2017 and less than a third of tests were 3-site. To promote sexual health and STD prevention among PLWH who are MSM, research regarding the added value of CT and GC testing across 3 anatomic sites is needed.

Abstract
INTRODUCTION The goal of this study is to improve overall screening, detection, and treatment of Neisseria gonorrhea (GC) and Chlamydia trachomatis (CT) at our institution. MATERIALS AND METHODS An observational study with two phases was conducted at a U.S. Army Medical Center. Previously collected samples from January 2014 through December 2015 were compared to prospectively collected data from March 2016 through December 2017. All data were collected from a convenience sample of active duty, HIV-positive men who have sex with men. Concordance between provider-collected and self-collected extragenital screening (EGS) samples was evaluated. RESULTS The rate of detection using EGS was higher than previously found using urogenital screening alone. Our prospective analysis revealed that expanding screening to include extragenital sites increased rates of detection of GC and CT. Our rates of GC detection at the pharynx and rectum, and CT detection at the rectum, were higher than those reported in the literature for men who have sex with men. Rates of CT infection at the pharynx were comparable with those reported in the literature. Detection of GC at the pharynx was exactly concordant between self-collected and provider-collected samples. Concordance of GC and CT detection at the rectum was very good. The kappa coefficient for detection of CT at the pharynx was zero, which corresponded to 44 out of 45 concordant observations. CONCLUSIONS Prior to implementation of EGS at our institution, we missed the opportunity to detect a substantial number of GC/CT infections with urogenital screening alone. Our results suggest that self-collection is a reliable method of EGS as compared to provider collection of samples.

Abstract
Background Recommendations for sexually transmitted infection (STI) screening vary significantly across countries. This study evaluated the prevalence of urogenital and extragenital infections with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG) in patients visiting a French STI clinic in the Indian Ocean region to determine whether current STI screening practices should be updated. Methods This cross-sectional study examined all patients who visited the STI clinic between 2014 and 2015. Triplex polymerase chain reaction screening for CT, NG, and MG was performed on urine, vaginal, pharyngeal, and anal specimens (FTD Urethritis Basic Kit, Fast Track Diagnostics, Luxembourg). Results Of the 851 patients enrolled in the study, 367 were women (367/851, 43.2%) and 484 were men (484/851, 56.0%). Overall, 826 urogenital specimens (826/851, 97.1%), 606 pharyngeal specimens (606/851, 71.2%), and 127 anal specimens (127/851, 14.9%) were taken from enrolled patients. The prevalence of urogenital CT and MG was high in women ≤25 years (19/186, 10.21%; 5/186, 2.69%) and in men who have sex with women ≤30 years (16/212, 7.54%; 5/212, 2.36%). Among patients with urogenital CT infection, 13.7% (7/51) had urethritis. All patients with urogenital MG infection were asymptomatic. Men who have sex with men had a high prevalence of pharyngeal CT (2/45, 4.44%) and NG (3/44, 6.81%) and a high prevalence of anal CT (2/27, 7.41%), NG (2/27, 7.40%), and MG (1/27, 3.70%). After excluding patients with concomitant urogenital infection, extragenital infections with at least 1 of the 3 pathogens were found in 20 swabs (20/91, 21.9%) taken from 16 patients (16/81, 19.7%), all of them asymptomatic. Conclusions Routine multisite screening for CT, NG, and MG should be performed to mitigate the transmission of STIs in high-risk sexually active populations.

Abstract
Gonorrhoea is a major public health concern globally. Increasing incidence and sporadic ceftriaxone-resistant cases, including treatment failures, are growing concerns. The 2020 European gonorrhoea guideline provides up-to-date evidence-based guidance regarding the diagnosis and treatment of gonorrhoea. The updates and recommendations emphasize significantly increasing gonorrhoea incidence; broad indications for increased testing with validated and quality-assured nucleic acid amplification tests (NAATs) and culture; dual antimicrobial therapy including high-dose ceftriaxone and azithromycin (ceftriaxone 1 g plus azithromycin 2 g) OR ceftriaxone 1 g monotherapy (ONLY in well-controlled settings, see guideline for details) for uncomplicated gonorrhoea when the antimicrobial susceptibility is unknown; recommendation of test of cure (TOC) in all gonorrhoea cases to ensure eradication of infection and identify resistance; and enhanced surveillance of treatment failures when recommended treatment regimens have been used. Improvements in access to appropriate testing, test performance, diagnostics, antimicrobial susceptibility surveillance and treatment, and follow-up of gonorrhoea patients are essential in controlling gonorrhoea and to mitigate the emergence and/or spread of ceftriaxone resistance and multidrug-resistant and extensively drug-resistant gonorrhoea. This review provides the detailed background, evidence base and discussions, for the 2020 European guideline for the diagnosis and treatment of gonorrhoea in adults (Unemo M, et al. Int J STD AIDS. 2020).

Abstract
Background Not all men who have sex with men (MSM) at risk for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) infection currently receive sexual healthcare. To increase the coverage of high-quality HIV/STI care for MSM, we developed a home-care programme, as extended STI clinic care. This programme included home sampling for testing, combined with treatment and sexual health counselling. Here, we pilot implemented the programme in a hospital setting (HIV-positive MSM) to determine the factors for the successful implementation of STI home sampling strategies. Methods Healthcare providers from the HIV hospital treatment centre (Maastricht) were invited to offer free STI sampling kits (syphilis, hepatitis B, [extra]genital chlamydia and gonorrhoea laboratory testing) to their HIV-positive MSM patients (March to May 2018). To evaluate implementation of the program, quantitative and qualitative data were collected to assess adoption (HIV care providers offered sampling kits to MSM), participation (MSM accepted the sampling kits) and sampling-kit return, STI diagnoses, and implementation experiences. Results Adoption was 85.3% (110/129), participation was 58.2% (64/110), and sampling-kit return was 43.8% (28/64). Of the tested MSM, 64.3% (18/28) did not recently (< 3 months) undergo a STI test; during the programme, 17.9% (5/28) were diagnosed with an STI. Of tested MSM, 64.3% (18/28) was vaccinated against hepatitis B. MSM reported that the sampling kits were easily and conveniently used. Care providers (hospital and STI clinic) considered the programme acceptable and feasible, with some logistical challenges. All (100%) self-taken chlamydia and gonorrhoea samples were adequate for testing, and 82.1% (23/28) of MSM provided sufficient self-taken blood samples for syphilis screening. However, full syphilis diagnostic work-up required for MSM with a history of syphilis (18/28) was not possible in 44.4% (8/18) of MSM because of insufficient blood sampled. Conclusion The home sampling programme increased STI test uptake and was acceptable and feasible for MSM and their care providers. Return of sampling kits should be further improved. The home-care programme is a promising extension of regular STI care to deliver comprehensive STI care to the home setting for MSM. Yet, in an HIV-positive population, syphilis diagnosis may be challenging when using self-taken blood samples.

Abstract
Gonorrhoea is a major public health concern globally. Increasing incidence and sporadic ceftriaxone-resistant cases, including treatment failures, are growing concerns. The 2020 European gonorrhoea guideline provides up-to-date evidence-based guidance regarding the diagnosis and treatment of gonorrhoea. The updates and recommendations emphasize significantly increasing gonorrhoea incidence; broad indications for increased testing with validated and quality-assured nucleic acid amplification tests and culture; dual antimicrobial therapy including high-dose ceftriaxone and azithromycin (ceftriaxone 1 g plus azithromycin 2 g) OR ceftriaxone 1 g monotherapy (ONLY in well-controlled settings, see guideline for details) for uncomplicated gonorrhoea when the antimicrobial susceptibility is unknown; recommendation of test of cure (TOC) in all gonorrhoea cases to ensure eradication of infection and identify resistance; and enhanced surveillance of treatment failures when recommended treatment regimens have been used. Improvements in access to appropriate testing, test performance, diagnostics, antimicrobial susceptibility surveillance and treatment, and follow-up of gonorrhoea patients are essential in controlling gonorrhoea and to mitigate the emergence and/or spread of ceftriaxone resistance and multidrug-resistant and extensively drug-resistant gonorrhoea. For detailed background, evidence base and discussions, see the background review for the present 2020 European guideline for the diagnosis and treatment of gonorrhoea in adults (Unemo M, et al. Int J STD AIDS. 2020).

Abstract
Sexually transmitted infections (STIs) have been explored in various sexual subgroups. While excellent, these analyses have primarily occurred from uniquely biologic, epidemiologic, or sociologic perspectives. Missing from these discussions has been in-depth presentations of the dynamics of STI transmission from all three viewpoints simultaneously. In this paper, I present information about STI transmission for each STI, including considerations of prevalence, and then review the STI research and of the concept of risk. I then apply these three considerations to a fictitious case study to show their importance and utility. I close by arguing that this information could strengthen future sociologic reviews of STIs and sexual health by helping such researchers include more nuanced understandings about STIs.

Abstract
BACKGROUND Rectal infection with Chlamydia trachomatis (CT) is frequent in women who deny receptive anal sex and is thought to arise from autoinoculation of the rectum from vaginal secretions. An alternate hypothesis is that oral sex inoculates and establishes gastrointestinal tract infection. Distinguishing these hypotheses is difficult in women. In men, autoinoculation is unlikely and heterosexual men frequently perform oral sex, but rarely participate in receptive anal exposure behaviors. METHODS We enrolled high-risk men with and without nongonococcal urethritis who presented to a sexually transmitted infection clinic in Indianapolis, Indiana. Urine and rectal swabs were collected and tested for urogenital and rectal CT, Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG). Men completed surveys concerning symptoms, sexual orientation, and detailed recent and lifetime oral and anal sexual behaviors. RESULTS Rectal CT was detected in 2/84 (2.4%) heterosexual men who reported cunnilingus, but no lifetime receptive anal behaviors. All of the men who denied receptive anal behaviors were negative for rectal NG and MG. In homosexual and bisexual men, rectal CT prevalence was high (9.7%), and rectal NG (4.8%) and MG (4.8%) were also detected. CONCLUSIONS We detected rectal CT infections in heterosexual men who reported cunnilingus but denied receptive anal behaviors. Oral sex may be a risk factor for rectal CT infection via oral inoculation of the gastrointestinal tract.

A longitudinal study to investigate previous Chlamydia trachomatis infection as a risk factor for subsequent anorectal infection in men who have sex with men (MSM) and women visiting STI clinics in the Netherlands.

Abstract
Although anorectal Chlamydia trachomatis (CT) infections are frequently diagnosed in men who have sex with men (MSM) and women, the reason for this infection often remains unexplained, as anal sex is not always reported. Oropharyngeal infections inoculating the gastrointestinal (GI) tract may contribute to anorectal-CT infections, as evidence in animals suggests that chlamydia bacteria undergo GI passage; however, no evidence exists in humans. Longitudinal patient clinic-registry data from MSM (n = 17 125) and women (n = 4120) from two Dutch sexually transmitted infection clinics were analysed. When adjusting for confounding socio-demographics, co-infections and risk behaviour, previous (from 3 weeks up to 24 months) oropharyngeal CT was not a risk factor for subsequent anorectal CT in women (odds ratio (OR) 0.46; 95% confidence interval (CI) 0.18–1.18; P = 0.11) and MSM (OR 1.33; 95% CI 0.86–2.07; P = 0.204). Despite the large dataset, the numbers did not allow for the estimation of risk in specific subgroups of interest. The role of the GI tract cannot be excluded with this epidemiological study, but the impact of preceding oropharyngeal CT on anorectal-CT infection is likely limited.

Abstract
We analyzed the incidence and predictors of symptomatic repeat Neisseria gonorrhoeae (NG) infection among men who have sex with men (MSM) enrolled in the Bangkok MSM Cohort Study. Thai MSM aged ≥18 years were enrolled during 2006–2010 and followed every four months. At baseline, participants were screened for rectal and urethral NG and Chlamydia trachomatis (CT) infections using nucleic acid amplification testing (NAAT), rectal and pharyngeal NG by culture, and pharyngeal CT by NAAT. During follow-up, symptomatic participants were tested for NG infection by NAAT and Gram stain of rectal or urethral specimens. Among 1464 participants without NG infection at the baseline visit and having at least one follow-up visit, 11.2% (164/1464) developed symptomatic NG infection, for a total of 251 infections. Symptomatic repeat NG infection occurred in 28.0% (46/164) of participants. The incidence rate was 3.9 cases per 100 person-years. Baseline predictors of repeat symptomatic NG were as follows: unknown human immunodeficiency virus (HIV) status despite history of HIV testing, previous sexually transmitted infection diagnosis by physician, insertive-only anal intercourse without a condom, amyl nitrate use at baseline, CT infection at baseline, age 18–24 years, and being a student; HIV infection at baseline or during the study period was also associated with repeat symptomatic NG infection.

Abstract
OBJECTIVES Most international STI guidelines recommend Chlamydia trachomatis anorectal testing in women after self-reported sexual exposure or symptoms in women. However, it has been shown that the prevalence of anorectal C. trachomatis is as high (7%-17 %) in women who do not report anorectal intercourse (AI) as in women who do. This study assessed the correlation between the genital and anorectal C. trachomatis load in concurrently infected women for increased microbiological insight. METHODS A convenience sample of 105 women with a concurrent (genital and anorectal) C. trachomatis infection was included from the STI clinic in South Limburg, the Netherlands. Women provided self-collected vaginal and anorectal swabs. The C. trachomatis load was quantified with qPCR and the human cell load was assessed to ensure sample adequacy. Genital and anorectal C. trachomatis loads were divided into tertiles for comparison. The χ2 test and linear regression were used to compare genital and anorectal C. trachomatis loads and identify determinants associated with load. RESULTS The overall median C. trachomatis load was higher in genital (median 5.3 log10 C. trachomatis/ml) than anorectal samples (median 3.4, p ≤ 0.001), but both loads were within the same range. The genital and anal load categories were not related within one woman (p = 0.99), both in women with and without AI. The anorectal C. trachomatis load was in the same or higher load category than the genital load in 56% of women without AI, and 79% of women with AI. CONCLUSIONS Although no cut-off for clinical relevance is known, an anorectal C. trachomatis load in the same or higher load category than the genital C. trachomatis load is likely to be clinically relevant. Other measurements should also be taken into account, such as leucocytes or bacterial viability to distinguish infection from contamination or exposure.

Abstract
OBJECTIVE Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections can clear without treatment. Despite high prevalence of anorectal infections in men who have sex with men (MSM) and women, studies on anorectal clearance are scarce. Moreover it is unknown whether bacterial load affects urogenital/anorectal CT clearance. In this prospective cohort study, CT and NG clearance is assessed at three anatomical sites of men and women. METHODS CT-positive and NG-positive MSM, heterosexual men and women ≥18 years of age visiting our STI clinic between 2011 and 2013 underwent a repeat test when returning for treatment (n=482). The primary outcome was clearance, defined as a positive nucleic acid amplification test (NAAT) at screening-consultation, followed by a negative NAAT at treatment-consultation. Sociodemographics, sexual risk behaviour and CT bacterial load (inhouse quantitative PCR) were tested as determinants for clearance using multivariable logistic regression for CT and Fisher's exact test for NG. RESULTS CT clearance was 9.1% (10/110) for urine, 6.8% (20/292) for vaginal swabs, 12.7% (8/63) for anorectal swabs (ie, 4.0% [1/25] in MSM and 18.4% [7/38] in women) and 57.1% (4/7) for oropharyngeal swabs. For NG this was 33.3% (2/6), 28.6% (2/7), 20.0% (2/10) and 27.3% (6/22), respectively. The number of days between tests (median 10, IQR 7-14) was not associated with clearance. Lower bacterial load at screening was the only predictor for CT clearance (urine mean 1.2 vs 2.6 log CT/mL, p=0.001; vaginal swabs mean 2.1 vs 5.2 log CT/mL p<0.0001; anorectal swabs mean 2.0 vs 3.7 log CT/mL, p=0.002). None of the tested determinants were associated with NG clearance. CONCLUSIONS This study reports the largest number of anorectal infections tested for CT and NG clearance to date. Clearance in all sample types was substantial: between 7% and 57% for CT, and between 20% and 33% for NG (notwithstanding low absolute numbers). CT clearance was associated with a lower load at screening. However, not all individuals with low bacterial CT load cleared the infection, hampering STI guideline change.

Abstract
This article provides a narrative overview of research on HIV/STI risk and collective sexual behavior based on an inclusive analysis of research on environments where people gather for sexual activity-sex clubs, swingers' clubs, bathhouses, parks, private sex parties, etc. The aim is to analyze how collective sex has been approached across disciplines to promote conversation across paradigms and suggest new lines of inquiry. Attention to context-such as the location of sex-was a necessary redress to universalizing models of sexual risk-taking behavior, leading to insights rooted in the particularities of each environment and its users. However, the identification of ever more precise risk groups or environmental idiosyncrasies eventually becomes theoretically restrictive, leading to an overestimation of the uniqueness of sexual enclaves, and of the difference between any given enclave and the broader social milieu. Using a theoretical framework of transgression to interpret the interdisciplinary literature, similarities in the spatial and social organization of collective sex environments are identified. Insights generated from this complementary perspective are then applied to understandings of collective sex: first, the example of male-female (MF) "swingers" is used to illustrate the need to establish, rather than assume, the distinctiveness of each non-normative sexual enclave, and to broaden the conceptualization of context; second, questions are raised about the practicality of interventions in collective sex environments. Finally, new lines of intellectual inquiry are suggested to shed light not just on collective sex but on sociosexual issues more generally, such as increasing protective sexual health behavior or negotiating consent in sexual encounters.

Abstract
INTRODUCTION Rates of sexually transmitted infection (STI) are rising in the USA, yet STI risk remains under-addressed by providers, even in HIV care, and with high-risk patients. We interviewed primary care patients living with and without HIV regarding circumstances surrounding sexual risk behavior to identify opportunities for providers to address and reduce STI risk. METHODS We conducted semi-structured 1:1 interviews with patients living with and without HIV reporting ≥ 1 sex partner and varying STI exposure risk in the past 12 months from four geographically diverse US HIV and primary care clinics. We audio-recorded, transcribed, and coded interviews by circumstance type, using double-coding to ensure inter-coder reliability. We used Fisher's exact and T tests to determine associations with demographic/risk factors. RESULTS Patients (n = 91) identified a mean of 3 of 11 circumstances. These included substance use (54%), desire for physical/emotional intimacy (48%), lack of HIV/STI status disclosure (44%), psychological drivers (i.e., coping, depression; 38%), personal dislike of condoms (22%), partner condom dislike/refusal (19%), receiving payment for sex (13%), and condom unavailability (9%). Higher proportions of those who were high STI-exposure risk patients, defined as those with ≥ 2 sex partners in the past 3 months reporting never or sometimes using condoms, reported disliking condoms (p = .006); higher proportions of the high-risk and moderate-risk (≥ 2 partners and condom use "most of the time") groups reported substance use as a circumstance (p = .04). CONCLUSION Circumstances surrounding perceived STI exposure risk were diverse, often overlapping, and dependent on internal, environmental, and partner-related factors and inadequate communication. Meaningful care-based interventions regarding HIV/STI transmission behavior must address the diversity and interplay of these factors.

Abstract
Extragenital infections can occur concurrently with simultaneous urogenital infections. Extragenital sites are believed to serve as hidden reservoirs and play a critical role in their transmission. The etiological relationship of the most widespread Sexually transmitted diseases (STD) pathogen to reproductive tract has long been established, but the distribution to extragenital sites appears to be infrequent and its correlation with the sexual practice still requires to be investigated. Optimal-screening strategies for extragenital infections are largely unknown. However, there is a lack of data on clinical outcomes and optimal treatment regimens for rectal and pharyngeal extragenital infections. Further studies are needed in settings other than reproductive health and STD clinics, especially in primary care clinics and resource-limited settings.

Abstract
INTRODUCTION Chlamydia trachomatis (chlamydia) is the most commonly diagnosed bacterial sexually transmitted infection (STI) worldwide. The advancement of molecular techniques has made chlamydia diagnostics infinitely easier. However, molecular techniques lack the information on chlamydia viability. Where in routine diagnostics the detection of chlamydia DNA or RNA might suffice, in other patient scenarios, information on the viability of chlamydia might be essential. Areas covered: In this review, the authors discuss the specific strengths and limitations of currently available methods to evaluate chlamydia viability: conventional cell culture, messenger RNA (mRNA) detection and viability-PCR (V-PCR). PubMed and Google Scholar were searched with the following terms: Chlamydia trachomatis, Treatment failure, Anal chlamydia, Microbial viability, Culture, Viability-PCR, Messenger RNA, and Molecular diagnostics Expert commentary: Several techniques are currently available to determine chlamydia viability and thus the clinical relevance of a positive test result in clinical samples. Depending on the underlying research question, all three discussed techniques have their merits when testing for viability. However, mRNA methods show the most promise in determining the presence of a true infection, in case the chlamydia reticulate body can be specifically detected. Further research is needed to understand how to best apply viability testing in current chlamydia diagnostics.

Abstract
PURPOSE We assessed the prevalence and predictors of Chlamydia trachomatis, Neisseriagonorrhoeae and Mycoplasmagenitalium rectal infections in a population of 'men having sex with men' (MSM). METHODOLOGY From January to November 2017, 165 MSM attending a STI outpatients clinic in Bologna (Italy) and reporting unsafe anal intercourses were enrolled. An ano-rectal swab was collected from each patient: chlamydial and gonococcal infections were diagnosed by a commercial NAAT, whereas an in-house quantitative PCR was used for M. genitalium detection. In addition, 131 urine samples and 84 pharyngeal swabs underwent testing for C. trachomatis and N. gonorrhoeae. A molecular C. trachomatis typing, a serological screening for anti-Chlamydia IgG and IgA, as well as the assessment of HIV, HCV and syphilis infections, were performed.Results/Key findings. The prevalence of C. trachomatis, N. gonorrhoeae and M. genitalium rectal infections was 27.2, 25.4 and 4.8 %, respectively. Globally, 63.1 % of cases were asymptomatic and up to 80 % of chlamydial and gonococcal infections would have been missed if the rectal site had not been tested. All the patients with rectal M. genitalium carriage were asymptomatic and characterized by low bacterial loads (<2500 DNA copies/reaction). Lymphogranuloma venereum (LGV) prevalence was 12.1 % with a considerable proportion of asymptomatic infections (35 %). The presence of symptoms, age >30, HIV-positivity and elevated levels of anti-Chlamydia antibodies were the most significant predictors of LGV. CONCLUSIONS Sexually transmitted rectal infections are frequent and often asymptomatic among MSM. LGV prevalence is high in our country and there is increasing evidence of symptomless cases.

Abstract
Background. Testing on indication of self-reported anal sex or symptoms is used to manage anorectal Chlamydia trachomatis (chlamydia) and Neisseria gonorrhoeae (gonorrhea) infections in women. Little is known about the impact of another testing strategy, routine universal anorectal screening with respect to chlamydia and gonorrhea prevalence and risk factors. Methods. All women (n = 1012) aged ≥16 years attending our sexually transmitted infection clinic in 2015 were offered routine universal screening. In total, 19.5% (n = 185) of women had an indication (reported anal sex or symptoms), 72.5% (n = 689) did not have an indication, and 8.0% (n = 76) had missing information on indication. Logistic regression analyses were used to identify determinants associated with anorectal chlamydia and gonorrhea. Results. Of all women who visited our clinic, 94% (n = 950) participated in the study. Overall anorectal chlamydia/gonorrhea positivity was 13.4% (n = 127)/1.3% (n = 12). Self-reported anal sex and anal symptoms were independently associated with anorectal gonorrhea (odds ratios [ORs], 3.3 [95% confidence interval {CI}, 1.01-10.7] and 14.5 [95% CI, 2.8-75.0], respectively), but not with anorectal chlamydia. Of all anorectal chlamydia/gonorrhea cases, 72% (n = 92)/33% (n = 4) were diagnosed in women without an indication, of which 19% (n = 19)/0% (n = 0) were anorectal only. For women with missing indication, this was 7% (n = 9)/8% (n = 1) and 44% (n = 4)/100% (n = 1). Conclusions. Anorectal screening in women without an indication is feasible and highly acceptable. Selective testing on indication could be an appropriate control strategy for anorectal gonorrhea, as few infections would be missed. In contrast, selective testing is a suboptimal control strategy for anorectal chlamydia, as we found a high prevalence in women both with and without indication for anorectal testing, along with a substantial amount of anorectal-only infections.

Abstract
BACKGROUND Men who have sex with men with HIV have high sexually transmitted infection (STI) incidence. Thus, the Centers for Disease Control and Prevention (CDC) recommends at least yearly STI screening of HIV-infected individuals. METHODS We calculated testing rates for syphilis, chlamydia, and gonorrhea among HIV-positive Californians with Medicare or Medicaid insurance in 2010. Logistic regressions estimated how testing for each bacterial STI relates to demographic and provider factors. RESULTS Fewer than two-thirds of HIV-positive Medicare and fewer than three-quarters of Medicaid enrollees received a syphilis test in 2010. Screenings for chlamydia or gonorrhea were less frequent: approximately 30% of Medicare enrollees were tested for chlamydia or gonorrhea in 2010, but higher proportions of Medicaid enrollees were tested (45%-46%). Only 34% of HIV-positive Medicare enrollees who were tested for syphilis were also screened for chlamydia or gonorrhea on the same day. Nearly half of Medicaid enrollees were tested for all 3 STIs on the same day. Patients whose providers had more HIV experience had higher STI testing rates. CONCLUSIONS Testing rates for chlamydia and gonorrhea infection are low, despite the increase in these infections among people living with HIV and their close association with HIV transmission. Interventions to increase STI testing include the following: prompts in the medical record to routinely conduct syphilis testing on blood drawn for viral load monitoring, opt-out consent for STI testing, and provider education about the clinical importance of STIs among HIV-positive patients. Last, it is crucial to change financial incentives that discourage nucleic acid amplification testing for rectal chlamydia and gonorrhea infections.

Abstract
We report positivity rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection at each anatomic site among asymptomatic men who have sex with men (MSM). We calculated the number needed to screen (NNS) to detect CT and NG infection at each anatomic site. From 2006 to 2010, we enrolled Thai MSM, age ≥ 18 years into the Bangkok MSM Cohort Study. Participants underwent physical examination and had rectal, urethral, and pharyngeal screening for CT and NG infection using nucleic acid amplification tests (NAATs). Of 1744 enrollees, 1696 (97.2%) had no symptoms of CT and NG infection. The positivity rates of CT and NG infection at any site were 14.3% (rectum, urethra, pharynx) and 6.4% (rectum, urethra), respectively. The NNS to detect rectal CT and rectal NG infections was 10 and 16, respectively (p < 0.05). For urethral infection, the NNS of CT was lower than the NNS of NG (22, 121: p < 0.05). The lowest NNS found for rectal CT infection was in HIV-infected MSM (6, 5-8). Asymptomatic CT and NG infection were common among MSM in Bangkok, Thailand and frequently detected in the rectum. In setting where screening in all specimens using NAAT is not feasible, rectal screening should be a priority.

Abstract
Swingers are couples practicing consensual extradyadic heterosexual relations. This subculture is defined by venues and online communities. This study aimed to assess swingers' lifestyle, sexual health, and history of testing for sexually transmitted infections (STIs) and to review risk factors for sexual risk behavior and STI transmission. An online survey was distributed through venues, chat websites, and dating websites. Most of 480 swingers starting the survey completed it (n = 392, 81.6%). Women (n = 146) reported more frequent swinging (p = 0.013), same-sex contacts (p < 0.001), and more sex under influence of alcohol (p < 0.001). Men (n = 334) reported more anal sex (p = 0.002) and condomless vaginal sex (p = 0.004). Of respondents tested, 25.7% ever received an STI diagnosis. Using logistical regression, being male, older, single, and party drug use were associated with sexual risk behavior (p = 0.009). Higher frequency of swinging was associated with an STI diagnosis (p = 0.036). Swingers were sexually active, reported factors associated with sexual risk behavior, and were more diagnosed with an STI compared to the general population. Many swingers were tested for STIs. Nonetheless, implementation of tailored testing strategies should be considered given their elevated risk for STI acquisition.

Abstract
Adding universal rectal screening to urogenital screening should positively impact rectal Chlamydia trachomatis (CT) incidence in affected populations. A dynamic Markov model was used to evaluate costs and outcomes of three rectal CT screening strategies among women attending sexually transmitted infection clinics in Alberta, Canada: universal urogenital-only screening (UG-only), additional selected (exposure-based) rectal screening (UG+SR), and additional universal rectal screening (UG+UR). The model included two mutually exclusive health states: infected and susceptible. Additionally, the model included two rounds of transmission: male sex partners of women infected with rectal-only CT and female sex partners of those men. CT complications impacting patients' quality of life (QALY) were considered. Alberta and Canadian data were used to estimate model inputs. We used a health care perspective, a time period of 10 years, and a discount rate of 3% for analyses. Compared to UG-only screening, the incremental cost effectiveness ratios (ICERs) were CA$34,000 and CA$49,000 per QALY gained for UG+SR and UG+UR screening strategies, respectively. Compared to UG+SR, the ICER was CA$62,000 per QALY gained for the UG+UR strategy. Both adjunct selected and universal rectal screening strategies are cost effective compared to UG-only screening, and UG+UR screening is cost effective when compared to UG+SR screening.

Abstract
Identification of priority populations such as men who have sex with men (MSM) is important in surveillance systems to monitor trends of sexually transmitted infections (STIs). We explored using routinely collected non-behavioural data as a means to establish MSM status in surveillance by assessing anorectal swab as a marker of male-to-male sexual exposure. We used chlamydia testing data from a sexual health clinic, 2007-2012. Men reporting any male sexual partner(s) in the previous 12 months were considered MSM. The dataset was split into development and validation samples to develop a univariate predictive model and assess the model fit. The dataset included 30 358 individual men and 48 554 episodes of STI testing; 45% were among reported MSM and an anorectal swab was performed in 40% of testing episodes. Anorectal swabbing had good diagnostic performance as a marker for MSM status (sensitivity = 87%, specificity = 99%, positive predictive value = 98·6%, negative predictive value = 90·3%). The model showed good fit against the internal validation sample (area under the curve = 0·93). Anorectal swabs are a valid marker of MSM behaviour in surveillance data from sexual health clinics, and they are likely to be particularly useful for monitoring STI trends among MSM with higher risk behaviour.

Abstract
OBJECTIVE Swingers, that is, heterosexuals who as a couple have sex with others, including group sex and bisexual behaviour, are an older-aged risk group for STIs. Here, we report on their repeat testing (reattendance) and STI yield compared with other heterosexuals and men who have sex with men (MSM, homosexual men) at two Dutch STI clinics. METHODS Swingers are routinely (since 2006, South Limburg, registration-completeness: 99%) or partially (since 2010, Amsterdam, registration-completeness: 20%) included in the clinic patient registries. Data (retrospective cohort) are analysed to assess incidence (per 100 person-years (PY)) of reattendance and STI (Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG)) and associated factors calculating HRs. RESULTS In South Limburg 7714 and in Amsterdam 2070 swinger consultations were identified. Since 2010, swingers' incidence of reattendance was 48-57/100 PY. Incidence was lower in MSM (30-39/100 PY, HR 0.56; 95% CI 0.51 to 0.61, South Limburg; HR 0.88; 95% CI 0.80 to 0.96, Amsterdam), heterosexual men (8-14/100 PY, HR 0.16; 95% CI 0.15 to 0.17, South Limburg; HR 0.33; 95% CI 0.30 to 0.36, Amsterdam) and women (13-20/100 PY, HR 0.56; 95% CI 0.51 to 0.61, South Limburg; HR 0.46; 95% CI 0.42 to 0.51, Amsterdam). Swingers' STI incidence at reattendance was 11-12/100 PY. Incidence was similar in heterosexual men (14-15/100 PY; HR 1.19; 95% CI 0.90 to 1.57, South Limburg; HR 1.20; 95% CI 0.91 to 1.59, Amsterdam) and women (12-14/100 PY; HR 1.14; 95% CI 0.88 to 1.49, South Limburg; HR 0.98; 95% CI 0.74 to 1.29, Amsterdam) and higher in MSM (18-22/100 PY; HR 1.59; 95% CI 1.19 to 2.12, South Limburg; HR 1.80; 95% CI 1.36 to 2.37, Amsterdam). Risk factors for STI incidence were partner-notified (contact-tracing), symptoms and previous STI. Swingers' positivity at any clinic attendance was 3-4% for NG (ie, higher than other heterosexuals) and 6-8% for CT (ie, lower than heterosexuals overall but higher than older heterosexuals). CONCLUSIONS Systematic identification reveals that swingers are part of the normal STI clinic populations. They frequently repeat test yet are likely under-recognised in clinics which not routinely ask about swinging. Given swingers' notable STI rates, usage of services is warranted, although use may be restricted, that is, to those with an STI risk factor (as did Dutch clinics). As swingers have dense sexual networks, enhancing contact-tracing may have high impact.

Design of the FemCure study: prospective multicentre study on the transmission of genital and extra-genital Chlamydia trachomatis infections in women receiving routine care. BMC Infect Dis 2016; 16:381. [PMID: 27502928 PMCID: PMC4977887 DOI: 10.1186/s12879-016-1721-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2016] [Accepted: 07/15/2016] [Indexed: 11/17/2022] Open
Abstract
Background In women, anorectal infections with Chlamydia trachomatis (CT) are about as common as genital CT, yet the anorectal site remains largely untested in routine care. Anorectal CT frequently co-occurs with genital CT and may thus often be treated co-incidentally. Nevertheless, post-treatment detection of CT at both anatomic sites has been demonstrated. It is unknown whether anorectal CT may play a role in post-treatment transmission. This study, called FemCure, in women who receive routine treatment (either azithromycin or doxycycline) aims to understand the post-treatment transmission of anorectal CT infections, i.e., from their male sexual partner(s) and from and to the genital region of the same woman. The secondary objective is to evaluate other reasons for CT detection by nucleic acid amplification techniques (NAAT) such as treatment failure, in order to inform guidelines to optimize CT control. Methods A multicentre prospective cohort study (FemCure) is set up in which genital and/or anorectal CT positive women (n = 400) will be recruited at three large Dutch STI clinics located in South Limburg, Amsterdam and Rotterdam. The women self-collect anorectal and vaginal swabs before treatment, and at the end of weeks 1, 2, 4, 6, 8, 10, and 12. Samples are tested for presence of CT-DNA (by NAAT), load (by quantitative polymerase chain reaction -PCR), viability (by culture and viability PCR) and CT type (by multilocus sequence typing). Sexual exposure is assessed by online self-administered questionnaires and by testing samples for Y chromosomal DNA. Using logistic regression models, the impact of two key factors (i.e., sexual exposure and alternate anatomic site of infection) on detection of anorectal and genital CT will be assessed. Discussion The FemCure study will provide insight in the role of anorectal chlamydia infection in maintaining the CT burden in the context of treatment, and it will provide practical recommendations to reduce avoidable transmission. Implications will improve care strategies that take account of anorectal CT. Trial registration ClinicalTrials.gov Identifier: NCT02694497.

Abstract
Chlamydia trachomatis is the most common bacterial sexually transmitted pathogen, but more than 70% of patients fail to seek treatment due to the asymptomatic nature of these infections. Women suffer from numerous complications from chronic chlamydial infections, which include pelvic inflammatory disease and infertility. We previously demonstrated in culture that host cell nectin-1 knockdown significantly reduced chlamydial titers and inclusion size. Here, we sought to determine whether nectin-1 was required for chlamydial development in vivo by intravaginally infecting nectin-1-/- mice with Chlamydia muridarum and monitoring chlamydial shedding by chlamydial titer assay. We observed a significant reduction in chlamydial shedding in female nectin-1-/- mice compared to nectin-1+/+ control mice, an observation that was confirmed by PCR. Immunohistochemical staining in mouse cervical tissue confirmed that there are fewer chlamydial inclusions in Chlamydia-infected nectin-1-/- mice. Notably, anorectal chlamydial infections are becoming a substantial health burden, though little is known regarding the pathogenesis of these infections. We therefore established a novel male murine model of rectal chlamydial infection, which we used to determine whether nectin-1 is required for anorectal chlamydial infection in male mice. In contrast to the data from vaginal infection, no difference in rectal chlamydial shedding was observed when male nectin-1+/+ and nectin-1-/- mice were compared. Through the use of these two models, we have demonstrated that nectin-1 promotes chlamydial infection in the female genital tract but does not appear to contribute to rectal infection in male mice. These models could be used to further characterize tissue and sex related differences in chlamydial infection.

Abstract
The implementation of express testing in an sexually transmitted infection (STI) clinic reduced the length of visit time compared with other visit types and increased the proportion of STIs diagnosed at clinic visits. Express testing did not impact the time to treatment for asymptomatic patients diagnosed as having an STI.

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
The aim of this study was to assess Chlamydia trachomatis (CT) infection prevalence and serovar distribution in a high-density urban area in the north of Italy, by comparing different groups of subjects divided on the basis of the type of care provider they referred to (STI Clinic, gynaecologists or general practitioners). From January 2011 to May 2014, all the specimens submitted to the Microbiology Laboratory of St Orsola Hospital in Bologna for CT detection were tested by PCR assay. For positive specimens, molecular genotyping based on RFLP analysis was performed. Total prevalence of CT infection was 8.1 %, with significant differences between subgroups (P<0.01) but stable during the study period. The STI Clinic was mainly responsible for CT diagnosis, whereas the lowest infection prevalence was detected in gynaecological clinics, despite the high number of tests performed. Extra-genital samples were almost exclusively collected from males at the STI Clinic. Interestingly, 13.3 % of patients providing extra-genital specimens were positive for CT on rectal and/or pharyngeal swabs, and 4.4 % of cases would have been missed if extra-genital sites had not been tested. The most common serovar was E, and serovar distribution was influenced by gender (P<0.01), age (P<0.01), care provider (P=0.01) and anatomical site (P<0.01). The L2 serovar was detected only in extra-genital samples from males at the STI Clinic. Knowledge about care providers' contributions in CT testing and diagnosis is essential for infection control. CT typing is crucial for appropriate management of specific infections, such as lymphogranuloma venereum in extra-genital samples of high-risk populations.

Abstract
OBJECTIVES Assessment of the relations between recorded gonorrhoea rates and clinical testing activity and disposable diagnostic tests. METHODS In Denmark, two sources of information on the epidemiology of gonorrhoea are available: (1) a mandatory clinical notification system (since 1867) comprising summary information about geographic distribution, season, age group and gender; in 1994, more detailed anonymous individualised epidemiological information was included; (2) a voluntary countrywide laboratory surveillance system for culture-confirmed cases (since 1957) comprising information about patient's age and gender, infected anatomical sites and medical setting attended. RESULTS Both surveillance systems showed marked simultaneous changes in gonorrhoea rates, although periodically considerable under-reporting or under-diagnosing was demonstrated. The annual incidence of notified cases peaked in 1919 (474/100,000), in 1944 (583/100,000) and in 1972 (344/100,000). Since 1995, the incidence has been at a low endemic level (1.5-10/100,000) and the total male/female incidence ratios were from 3 to 7 times higher than previously recorded. Among approximately 2 million persons tested during 1974-1988 78,213 men and 63,143 women with culture-confirmed gonorrhoea were identified. During this period, pharyngeal sampling was performed in 36% of men and 25% of women with gonorrhoea; pharyngeal gonorrhoea was found in 10% and 16%, respectively; 40% and 30% of these patients had no concomitant urogenital gonorrhoea. Among men with gonorrhoea, 34% were sampled from the rectum; 9% had rectal gonorrhoea, among whom the rectum was the only infected site in 67%. CONCLUSIONS Crucial factors for case finding are clinical sampling tradition and appropriate laboratory diagnostic facilities. When case finding is insufficient, a reservoir of asymptomatic rectal or pharyngeal gonorrhoea remains unrecognised.

What is needed to guide testing for anorectal and pharyngeal Chlamydia trachomatis and Neisseria gonorrhoeae in women and men? Evidence and opinion. BMC Infect Dis 2015; 15:533. [PMID: 26576538 PMCID: PMC4650297 DOI: 10.1186/s12879-015-1280-6] [Citation(s) in RCA: 74] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2015] [Accepted: 11/12/2015] [Indexed: 11/10/2022] Open
Abstract
Background Anorectal and pharyngeal infections with Chlamydia trachomatis (CT) and Neisseria gonorrheae (NG) are commonly observed in men who have sex with men (MSM). There is increasing evidence that such infections at extra-genital sites are also common in women. In both sexes, these infections are largely overlooked as they are not routinely tested for in regular care. Testing based on sexual behavior or symptoms would only detect half of these extra-genital infections. This paper elucidates the differences and similarities between women and MSM, regarding the epidemiology of extra-genital CT and NG. It discusses the clinical and public health impact of untested extra-genital infections, how this may impact management strategies, and thereby identifies key research areas. Discussion Extra-genital CT is as common in women as it is in MSM; NG in women is as common at their extra-genital sites as it is at their genital sites. The substantial numbers of extra-genital CT and NG being missed in women and MSM indicate a need to test and treat more patients and perhaps different choices in treatment and partner management strategies. Doing so will likely contribute to reduced morbidity and transmission in both sexes. However, in our opinion, it is clear that there are several knowledge gaps in understanding the clinical and public health impact of extra-genital CT and NG. Key research areas that need to be addressed concern associated morbidity (anorectal and reproductive morbidity due to extra-genital infections), ‘the best’ management strategies, including testing and treatment for extra-genital CT, extra-genital treatment resistance, transmission probabilities between partners and between anatomic sites in a woman, and impact on transmission of other infections. Data are also lacking on cost-effectiveness of pharyngeal testing, and of NG testing and anorectal CT testing in women. Gaps in the management of extra-genital CT and NG may also apply for other STIs, such Mycoplasma genitalium. Summary Current management strategies, including testing, to address extra-genital CT and NG in both sexes are suboptimal. Comparative data on several identified key themes in women and MSM are lacking and urgently needed to guide better management of extra-genital infections.

Abstract
This guideline offers recommendations on the diagnostic tests, treatment regimens and health promotion principles needed for the effective management of Chlamydia trachomatis genital infection. It covers the management of the initial presentation, as well the prevention of transmission and future infection. The guideline is aimed at individuals aged 16 years and older presenting to healthcare professionals working in departments offering Level 3 care in sexually transmitted infections management within the UK. However, the principles of the recommendations should be adopted across all levels, using local care pathways where appropriate.

Abstract
Screening persons living with HIV for gonorrhea and chlamydia has been recommended since 2003. We compared annual gonorrhea/chlamydia testing to syphilis and lipid testing among 19,368 adults (41% men who have sex with men, 30% heterosexual men, and 29% women) engaged in HIV care. In 2004, 22%, 62%, and 70% of all patients were tested for gonorrhea/chlamydia, syphilis, and lipid levels, respectively. Despite increasing steadily [odds ratio per year (95% confidence interval): 1.14 (1.13 to 1.15)], gonorrhea/chlamydia testing in 2010 remained lower than syphilis and lipid testing (39%, 77%, 76%, respectively). Interventions to improve gonorrhea/chlamydia screening are needed. A more targeted screening approach may be warranted.

Prevalence of and Factors Associated with Rectal-Only Chlamydia and Gonorrhoea in Women and in Men Who Have Sex with Men. PLoS One 2015; 10:e0140297.

Abstract
BACKGROUND Both anorectal Chlamydia trachomatis (CT) and Neisseria gonorrhoea (NG) can occur as a rectal-only infection or concurrently with simultaneous urogenital infection with the same pathogen. Characterising the target groups in which rectal-only infections occur may improve the efficacy of screening practices. METHODS We analysed data from two Dutch outpatient sexually transmitted infection (STI) clinics between 2011 and 2012. We included all men who have sex with men (MSM) (n = 9549) and women (n = 11113), ≥18 years, who had been tested for anorectal and urogenital CT and/or NG (either as a result of reporting anal sex/symptoms or via routine universal testing). Factors associated with rectal-only CT and NG infections were assessed using univariable and multivariable logistic regression. RESULTS In MSM, anorectal CT prevalence was 9.8% (693/7094), anorectal NG prevalence was 4.2% (397/9534). In women this was 9.5% overall (439/4597) and 0.9% (96/10972) respectively. Anorectal CT prevalence among women who were routinely universally tested was 10.4% (20/192), for selective testing this was 9.5% (419/4405) (p = 0.68). Anorectal NG infections were not detected among women who were routinely universally tested (p = 0.19). Among CT or NG positive MSM, rectal-only CT infections were found in 85.9% (595/693), for NG this was 85.6% (340/397) respectively. In positive women these figures were 22.1% (97/439)for CT and 20.8% (20/96) for NG, respectively. In MSM, independent factors associated with rectal-only CT were: being a sex worker (OR0.4,CI0.2-1.0), exclusively having sex with men (OR3.4,CI1.7-6.8), and absence of urogenital symptoms (OR0.2,CI0.2-0.4). In women, these factors were: older age (OR2.3, CI1.3-4.0) and non-Western nationality (OR1.8, CI1.0-3.5). Factors associated with rectal-only NG in MSM were: having been warned for STIs by an (ex) partner (OR2.9,CI1.1-7.5), oropharyngeal NG infection (OR2.4,CI1.0-5.3), and absence of urogenital symptoms (OR0.02,CI0.01-0.04), while in women no significant factors were identified. CONCLUSIONS The prevalence of anorectal CT and NG was substantial in MSM and prevalence of anorectal CT was also substantial in women. Anorectal infections occurred mostly as rectal-only infections in MSM and mostly concurrent with other infections in women. Given the lack of useful indicators for rectal-only infections, selective screening based on a priori patient characteristics will have low discriminatory power both in relation to MSM and women.

van Liere GAFS, Dirks JAMC, Hoebe CJPA, Wolffs PF, Dukers-Muijrers NHTM. Anorectal Chlamydia trachomatis Load Is Similar in Men Who Have Sex with Men and Women Reporting Anal Sex. PLoS One 2015; 10:e0134991. [PMID: 26262680 PMCID: PMC4532443 DOI: 10.1371/journal.pone.0134991] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Accepted: 07/15/2015] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Anorectal Chlamydia trachomatis (chlamydia) is frequently diagnosed in men who have sex with men (MSM) and in women, but it is unknown whether these infections are comparable in clinical impact and transmission potential. Quantifying bacterial load and identifying determinants associated with high bacterial load could provide more insight. METHODS We selected a convenience sample of MSM who reported anal sex (n = 90) and women with concurrent urogenital/anorectal chlamydia who reported anal sex (n = 51) or did not report anal sex (n = 61) from the South Limburg Public Health Service's STI unit. Bacterial load (Chlamydia/ml) was quantified for all samples and log transformed for analyses. Samples with an unquantifiable human leukocyte antigen (n = 9) were excluded from analyses, as they were deemed inadequately sampled. RESULTS The mean log anorectal chlamydia load (3.50) was similar for MSM and women who reported having anal sex (3.80, P = 0.21). The anorectal chlamydia load was significantly higher in these groups than in women who did not report having anal sex (2.76, P = 0.001). Detectable load values ranged from 1.81-6.32 chlamydia/ml for MSM, 1.74-7.33 chlamydia/ml for women who reported having anal sex and 1.84-6.31 chlamydia/ml for women who did not report having anal sex. Symptoms and several other determinants were not associated with anorectal chlamydia load. CONCLUSIONS Women who did not report anal sex had lower anorectal loads, but they were within a similar range to the other two groups. Anorectal chlamydia load was comparable between MSM and women who reported anal sex, suggesting similar transmission potential.

Abstract
We sought to determine the prevalence of rectal chlamydia and gonorrhea after the introduction of nucleic acid amplification tests for screening in men reporting receptive anal intercourse. The rectal chlamydia prevalence was 14.1% (95% confidence interval, 11.9-16.3), and the gonorrhea prevalence was 5.9% (95% confidence interval, 4.4-7.3). Most cases were positive only from the rectum.

Abstract
Chlamydia is the most commonly notified sexually transmitted infection in Australia. Australian guidelines recommend urogenital screening in asymptomatic men and women, and rectal screening in men who have sex with men or women reporting anal sex/symptoms. International studies describe a rectal chlamydia prevalence in women of 5% to 21%. We found that in women at high risk of chlamydia, 57% (32/56) tested positive for rectal chlamydia. Of these, 97% (31/32) had concurrent urogenital chlamydia. Women with urogenital chlamydia were significantly more likely to have a positive rectal result (χ(2), p = 0.000). Neither anal symptoms nor reported anal sex were associated with a positive rectal chlamydia test. The recommended treatment of rectal chlamydia differs substantially from that of urogenital chlamydia, raising the possibility that Australian women are being regularly undertreated due to a lack of rectal testing. Untreated rectal chlamydia may increase the risk of persistent infection, reproductive tract reinfection, complications and transmission. Further work is needed to determine the optimal management of chlamydia in women.

Abstract
BACKGROUND Testing women for urogenital Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) is common in sexually transmitted disease (STD) clinics. However, women may not be routinely tested for rectal GC/CT. This may lead to missed infections in women reporting anal intercourse (AI). METHODS This was a retrospective review of all women who underwent rectal GC/CT testing from August 2012 to June 2013 at an STD clinic in Columbus, Ohio. All women who reported AI in the last year had a rectal swab collected for GC/CT nucleic acid amplification testing (n=331). Using log-binomial regression models, we computed unadjusted and adjusted associations for demographic and behavioral factors associated with rectal GC/CT infection. RESULTS Participants (n=331) were 47% African-American, with median age of 29 years. Prevalence of rectal GC was 6%, rectal CT was 13%, and either rectal infection was 19%. Prevalence of urogenital GC and CT was 7% and 13% respectively. Among women with rectal GC, 14% tested negative for urogenital GC. Similarly, 14% of women with rectal CT tested negative for urogenital CT. In unadjusted analyses, there was increased rectal GC prevalence among women reporting sex in the last year with an injection drug user, with a person exchanging sex for drugs or money, with anonymous partners, and while intoxicated/high on alcohol or illicit drugs. After multivariable adjustment, no significant associations persisted, but a trend of increased rectal GC prevalence was observed for women <26 years of age (p=0.06) and those reporting sex while intoxicated/high on alcohol or drugs (p=0.05). For rectal CT, only age <26 years was associated with prevalent infection in unadjusted models; this association strengthened after multivariable adjustment (prevalence ratio: 6.03; 95% confidence interval: 2.29-15.90). CONCLUSION Nearly one in five women who reported AI in the last year had rectal GC or CT infection. Urogenital testing alone would have missed 14% of rectal infections. Standardized guidelines would increase rectal GC/CT testing in women and help detect missed infections.
