Abstract
BACKGROUND The incidence of sexually transmitted infections (STIs) is unbridled and on the rise. Extragenital STIs (anal and pharyngeal infections) are commonly asymptomatic, resulting in delayed diagnosis and treatment and consequently higher chances of onward transmission. OBJECTIVE The aim of this observational single-centre study was to determine the prevalence of STIs at extragenital sites in symptomatic and asymptomatic patients presenting at an STI outpatient clinic. METHODS We conducted a retrospective analysis of patients who presented between October 2019 and February 2021 at the STI outpatient clinic of a tertiary centre in Central Europe. Patients were included in the study if they received at least one pharyngeal and/or anorectal swab in addition to a genital swab for multiplex-PCR STI diagnostics. Demographic data, symptoms and serological results were collected and analysed. RESULTS Data collected from 440 patients were analysed (mean age: 33.9 years, male: n = 345, 78.4%, female: n = 95, 21.6%). Ninety-seven males reported having sex with men (MSM); 174 patients identified as heterosexual (132 males, 42 females), and 10 females as bisexual. The sexual orientation was not reported in 159 cases. An STI was confirmed in 195 patients (44.3%) and, among those, 109 patients (55.9%) tested positive for an STI at extragenital sites. Seventy-one patients had a pharyngeal STI whereas 61 were infected in the anorectal region. Of those suffering from an extragenital STI, 64.2% (70 out of 109) tested negative for relevant pathogens at genital sites. The most frequently detected extragenital pathogen was Neisseria gonorrhoeae (71.8% of all pharyngeal STIs [51 out of 71], 55.7% of anorectal STIs [34 out of 61]), followed by Chlamydia trachomatis (41.0% of all anal infections [25 out of 61], 5.6% of pharyngeal infections [4 out of 71]). Pharyngeal and anorectal infections were asymptomatic in 88.7% [63 out of 71] and 65.6% [40 out of 61] of the cases, respectively. CONCLUSION These results underline the need to perform multisite testing, regardless of the presence of symptoms.

Evaluation of Chlamydia trachomatis screening from the perspective of health economics: a systematic review. Front Public Health 2023; 11:1212890. [PMID: 37881345 PMCID: PMC10595018 DOI: 10.3389/fpubh.2023.1212890] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 09/22/2023] [Indexed: 10/27/2023] Open
Abstract
Background Most Chlamydia trachomatis (CT) infections are asymptomatic. The infection can persist and lead to severe sequelae. Therefore, screening for CT can primarily prevent serious sequelae. Aim To systematically evaluate CT screening from the perspective of health economics, summarize previous findings from different target populations, and make practical recommendations for developing local CT screening strategies. Methods PubMed, Web of Science, Embase, Cochran Library, and National Health Service Economic Evaluation Database (Ovid) were searched from January 1, 2000, to March 4, 2023. Studies reporting the cost-effectiveness, cost-benefit, or cost-utility of CT screening were eligible to be included. A narrative synthesis was used to analyze and report the results following the PRISMA guidelines. The Consensus on Health Economic Criteria (CHEC) list was used to assess the methodological quality of included studies. Results Our review finally comprised 39 studies addressing four populations: general sexually active people (n = 25), pregnant women (n = 4), women attending STD and abortion clinics (n = 4), and other high-risk individuals (n = 6). The total number of participants was ~7,991,198. The majority of studies assessed the cost-effectiveness or cost-utility of the screening method. The results showed that the following screening strategies may be cost-effective or cost-saving under certain conditions: performing CT screening in young people aged 15-24 in the general population, military recruits, and high school students; incorporating CT screening into routine antenatal care for pregnant women aged 15-30; opportunistic CT screening for women attending STD and abortion clinics; home-obtained sampling for CT screening using urine specimens or vaginal swab; performing CT screening for 14-30-year-old people who enter correctional institutions (i.e., jail, detention) as soon as possible; providing CT screening for female sex workers (FSWs) based on local incidence and prevalence; adding routine CT screening to HIV treatment using rectal samples from men who have sex with men (MSM). Conclusion We found that CT screening in general sexually active people aged 15-24, military recruits, high school students, pregnant women aged 15-30, women attending STD and abortion clinics, people entering jail, detention, FSWs, and MSM has health economic value. Due to the different prevalence of CT, diversities of economic conditions, and varying screening costs among different populations and different countries, regions, or settings, no uniform and standard screening strategies are currently available. Therefore, each country should consider its local condition and the results of health economic evaluations of CT screening programs in that country to develop appropriate CT screening strategies.

Abstract
Chlamydia trachomatis infection of ocular conjunctiva can lead to blindness, while infection of the female genital tract can lead to chronic pelvic pain, ectopic pregnancy, and/or infertility. Conjunctival and fallopian tube inflammation and the resulting disease sequelae are attributed to immune responses induced by chlamydial infection at these mucosal sites. The conserved chlamydial plasmid has been implicated in enhancing infection, via improved host cell entry and exit, and accelerating innate inflammatory responses that lead to tissue damage. The chlamydial plasmid encodes eight open reading frames, three of which have been associated with virulence: a secreted protein, Pgp3, and putative transcriptional regulators, Pgp4 and Pgp5. Although Pgp3 is an important plasmid-encoded virulence factor, recent studies suggest that chlamydial plasmid-mediated virulence extends beyond the expression of Pgp3. In this review, we discuss studies of genital, ocular, and gastrointestinal infection with C. trachomatis or C. muridarum that shed light on the role of the plasmid in disease development, and the potential for tissue and species-specific differences in plasmid-mediated pathogenesis. We also review evidence that plasmid-associated inflammation can be independent of bacterial burden. The functions of each of the plasmid-encoded proteins and potential molecular mechanisms for their role(s) in chlamydial virulence are discussed. Although the understanding of plasmid-associated virulence has expanded within the last decade, many questions related to how and to what extent the plasmid influences chlamydial infectivity and inflammation remain unknown, particularly with respect to human infections. Elucidating the answers to these questions could improve our understanding of how chlamydia augment infection and inflammation to cause disease.

The association between adverse pregnancy outcomes and non-viral genital pathogens among women living in sub-Saharan Africa: a systematic review. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1107931. [PMID: 37351522 PMCID: PMC10282605 DOI: 10.3389/frph.2023.1107931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 05/18/2023] [Indexed: 06/24/2023] Open
Abstract
Adverse pregnancy outcomes are the main causes of maternal and neonatal morbidity and mortality, including long-term physical and psychological sequelae. These events are common in low- and middle-income countries, particularly in Sub Saharan Africa, despite national efforts. Maternal infections can cause complications at any stage of pregnancy and contribute to adverse outcomes. Among infections, those of the genital tract are a major public health concern worldwide, due to limited availability of prevention, diagnosis and treatment approaches. This applies even to treatable infections and holds true especially in Sub-Saharan Africa. As late as 2017, the region accounted for 40% of all reported treatable non-viral genital pathogens worldwide, many of which have been independently associated with various adverse pregnancy outcomes, and that include Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Treponema pallidum. Two databases (PubMed and Embase) were examined to identify eligible studies published up to October 2022. This study reviewed findings on the association between infections by treatable non-viral genital pathogens during pregnancy and adverse pregnancy outcomes among women living in Sub-Saharan Africa. Articles' title and abstract were screened at first using keywords as "sexually transmitted infections", "non-viral", "adverse pregnancy outcome", "Africa", "sub-Saharan Africa", "pregnant women", "pregnancy", and "pregnancy outcome". Subsequently, according to the eligibility criteria, potential articles were read in full. Results showed that higher risk of preterm birth is associated with Treponema pallidum, Chlamydia trachomatis and Candida albicans infections. Additionally, rates of stillbirth, neonatal death, low birth weight and intrauterine growth restriction are also associated with Treponema pallidum infection. A better insight on the burden of non-viral genital pathogens and their effect on pregnancy is needed to inform antenatal care guidelines and screening programs, to guide the development of innovative diagnostic tools and other strategies to minimize transmission, and to prevent short- and long-term complications for mothers and children.

Abstract
BACKGROUND The Centers for Disease Control and Prevention recommends that men who have sex with men (MSM) get tested annually for urethral and rectal chlamydia (CT) and gonorrhea (NG), and pharyngeal NG. There are no national recommendations to screen women and heterosexual men at extragenital sites. We assessed extragenital CT/NG screening among men and women at Louisiana's Parish Health Units (PHU). METHODS The Louisiana STD/HIV/Hepatitis Program piloted extragenital screening at 4 PHUs in February 2016 and expanded to 11 PHUs in 2017. Sexual histories were used to identify gender of sex partners and exposed sites. Because of billing restrictions, up to 2 anatomical sites were tested for CT/NG. RESULTS From February 2016 to June 2019, 70,895 urogenital and extragenital specimens (56,086 urogenital, 13,797 pharyngeal, and 1,012 rectal) were collected from 56,086 patients. Pharyngeal CT positivity was 160 of 7,868 (2.0%) among women, 54 of 4,838 (1.1%) among men who have sex with women (MSW) and 33 of 1,091 (3.0%) among MSM. Rectal CT positivity was 51 of 439 (11.6%) among women and 95 of 573 (16.6%) among MSM. Pharyngeal NG positivity was 299 of 7,868 (3.8%) among women, 222 of 4,838 (4.6%) among MSW, and 97 of 1,091 (8.9%) among MSM. Rectal NG positivity was 20 of 439 (4.6%) among women and 134 of 573 (23.4%) among MSM.Urogenital-only screening would have missed: among women, 173 of 3,923 (4.4%) CT and 227 of 1,480 (15.3%) NG infections; among MSW, 26 of 2,667 (1%) CT and 149 of 1,709 (8.7%) NG infections; and among MSM, 116 of 336 (34.5%) CT and 127 of 413 (42.1%) NG infections. CONCLUSIONS Many CT/NG infections would have been missed with urogenital-only screening. Men who have sex with men had much higher extragenital infection rates than women and MSW.

Abstract
BACKGROUND Although molecular testing for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is highly sensitive, the cost can be prohibitive. Those high costs are amplified when the recommended screening approach is used, which requires separate testing of specimens from 3 anatomic sites (rectal, pharyngeal and urogenital). Although individual molecular testing is standard of care, pooled testing may offer a cost-saving alternative. METHODS Using the Xpert® CT/NG assay (Cepheid, Sunnyvale, CA) we tested urine, rectal and pharyngeal swabs for CT and NG in a high-risk cohort of participants assigned male at birth who reported sex with other persons who were assigned male at birth. Remnant specimens (0.34 mL from each anatomic site) were combined to perform a single 'pooled' test. We calculated positive and negative percent agreement between the pooled testing results with standard of care Xpert CT/NG test results as the reference. RESULTS We conducted 644 pooled tests. Of those, 598 (92.3%) gave CT and NG results. The CT-positive and -negative percent agreement were 90.1% (95% confidence interval [CI], 80.7-95.9%) and 99.2% (98.1-99.8%), respectively. The NG-positive and -negative percent agreement were 96.2% (95% CI, 86.8-99.5%) and 99.8% (95% CI, 99.0-100%), respectively. Pooled testing identified 4 CT and 1 NG infections that were negative at all anatomic sites by individual testing. CONCLUSIONS Three-site pooled CT and NG testing performs similarly to single anatomic site testing among tests providing a valid result. Future cost analyses should evaluate the cost effectiveness of pooled 3-site testing to determine if such a strategy improves the feasibility and accessibility of molecular sexually transmitted infection testing.

Abstract
BACKGROUND Despite high frequencies of oral and receptive anal intercourse among young women, the Centers for Disease Control and Prevention does not recommend routine oropharyngeal or anorectal screening for CT and GC. Risk-based extragenital screening of women has not been adopted at the majority of college health centers, and existing research has not focused on the female or college population. METHODS We examined health records of women at a college health center in a large urban university for 3 years to evaluate the effectiveness of CT and GC screening. We also evaluated the proportion of CT and GC infections that would have been missed if risk-based extragenital screening was not performed. Decisions to screen at extragenital sites were based on patient-reported risk behavior. RESULTS For 8027 unique chlamydia screens and 7907 unique gonorrhea screens, approximately 20% of the visits used extragenital screening in response to self-reported risk behaviors. More than 44% of patients were non-Hispanic White, and approximately 48% fell within the 20- to 24-year age group. The case positivity rates for CT were 2.85% with urogenital-only screening and 1.30% with risk-prompted extragenital screening (1.1% throat, 4.3% rectal). The case positivity rates for GC were 0.11% with urogenital-only screening and 0.37% with risk-prompted extragenital screening (0.37% throat, 0% rectal). If the college health center had relied solely on urogenital screening rather than adding risk-based extragenital screening, 4.41% of CT infections would have been missed and 28.57% of GC infections would have been missed. CONCLUSIONS Nearly 1 of 22 CT infections and nearly 1 of 3 GC infections would have been missed without extragenital screening in this analysis of college women. Inclusion of risk-prompted extragenital screening in asymptomatic STD screening protocols can help clinicians diagnose CT and GC infections that would be have been missed with urogenital-only screening. Although rectal GC infections among women seem to be less common, oropharyngeal testing, in particular, for GC is suggested for women based on sexual risk. However, clinicians might only identify these risks if they ask patients directly about these potential exposures. Because guidelines exist only for men, future studies should focus on extragenital screening in college women to build the evidence that this particular population of patients may benefit from this practice, given the high risk of STDs in young adults.

Routine universal testing versus selective or incidental testing for oropharyngeal Neisseria gonorrhoeae in women in the Netherlands: a retrospective cohort study. THE LANCET. INFECTIOUS DISEASES 2021; 21:858-867. [PMID: 33444559 DOI: 10.1016/s1473-3099(20)30594-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 02/02/2020] [Accepted: 06/23/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Women are not routinely tested for oropharyngeal Neisseria gonorrhoeae. At present, selective testing based on sexual behaviour or risk groups is advocated by international guidelines. Many oropharyngeal infections are asymptomatic and thus remain undetected, establishing a reservoir for ongoing transmission. Data on effectiveness of routine testing are scarce, thus we aimed to assess the optimal testing strategy for oropharyngeal N gonorrhoeae in women. METHODS In this retrospective cohort study, we used surveillance data obtained from all sexually transmitted infection (STI) clinics in the Netherlands between Jan 1, 2008, and Dec 31, 2017. We collected consultation-level data, and individual-level patient data from 2016 onwards, on sociodemographic characteristics, sexual behaviour in the past 6 months, self-reported symptoms, and STI diagnoses. We compared the prevalence of oropharyngeal N gonorrhoeae between women who attended clinics that offered routine universal testing (defined as >85% of women tested per clinic-year) and women who attended clinics that offered selective testing (defined as 5-85% of women tested per clinic-year) or incidental testing (<5% of women tested per clinic-year). We calculated the number of infections missed by selective testing by extrapolating prevalence for the routine universal testing group to that of weighted and unweighted samples of all selectively tested women. We used multivariable generalised estimating equations to identify independent risk factors for oropharyngeal N gonorrhoeae to identify the optimal selective testing strategy. FINDINGS 554 266 consultations with at least one N gonorrhoeae test were recorded, of which 545 750 consultations (including repeat visits) were included in the analyses. Of 545 750 consultations, routine universal testing was used in 57 359 (10·5%), selective testing in 444 283 (81·4%), and incidental testing in 44 108 (8·1%). The prevalence of oropharyngeal N gonorrhoeae was 1·4% (95% CI 1·3-1·5; 703 of 50 962 consultations) in the routine testing group compared with 1·4% (1·3-1·5; 1858 of 132 276) in the selective testing group (p=0·68) and 2·8% (1·9-3·9; 30 of 1088) in the incidental testing group (p<0·0001). The prevalence of oropharyngeal-only infections was 47·7% (335 of 703 women) in the routine testing group, 53·3% (991 of 1858) in the selective testing group, and 60·0% (18 of 30) in the incidental testing group. Selective testing would have missed an estimated 4363 (70%; 95% CI 69-71) of all 6221 oropharyngeal N gonorrhoeae infections. Independent risk factors for oropharyngeal N gonorrhoeae were being notified for any STI (adjusted odds ratio 2·1, 95% CI 1·5-3·0), reporting sex work (4·0, 2·3-6·7), and having concurrent genital (51·5, 34·1-77·7) or anorectal (2·6, 1·4-4·8) N gonorrhoeae. Selective testing of women notified for any STI, or who reported sex work, would have led to 5418 (27·8%) of 19 455 women being tested and would have identified 119 (55·6%) of 214 oropharyngeal N gonorrhoeae infections. INTERPRETATION Selective testing potentially misses more than two-thirds of oropharyngeal N gonorrhoeae infections in women, of whom half have oropharyngeal infections without concurrent genital or anorectal infections. Using independent risk factors for oropharyngeal infection to guide testing is a minimal testing strategy. Routine universal testing is the optimum scenario to detect the majority of infections. However, future studies are needed to assess the cost-effectiveness of routine testing and its effect on antimicrobial resistance. FUNDING Public Health Service South Limburg.

Abstract
OBJECTIVE Current guidelines for women do not include extragenital screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) and do not mention anal sex behaviour. The objective of this cross-sectional study was to determine the number of potentially missed CT and NG cases by relying on urogenital screening and self-reported anal sex behaviour among women. METHODS Demographic and clinical data of 4658 women attending a community health centre in Los Angeles, California, USA from 2015 to 2018 were examined. CT and NG were detected using nucleic acid amplification test (APTIMA Combo 2, Hologic Gen-Probe, San Diego, California). Demographic and behavioural factors were also examined to assess potentially missed NG/CT cases. Multivariable regression analyses were used to determine whether reported anal sex behaviour predicts NG/CT rectal infection. RESULTS A total of 193 NG cases and 552 CT cases were identified; however, 53.9% of NG cases and 25.5% of CT cases were identified exclusively through extragenital screening. Of all positive cases of rectal CT, 87.0% did not report anal sex without a condom and 91.3% did not report any anal sex with their last sexual partner. Of all positive cases of rectal NG, 78.9% did not report anal sex without a condom and 76.3% did not report any anal sex with their last sexual partner. Anal sex with last partner was not predictive of NG/CT rectal infection. CONCLUSIONS Relying solely on urogenital screening and reported behaviour misses NG/CT cases. Extragenital NG/CT screening should be conducted in all women regardless of reported anal sex behaviour.

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
Chlamydia spp. productively infect mucosal epithelial cells of multiple anatomical sites, including the conjunctiva, lungs, gastrointestinal (GI) tract, and urogenital tract. We, and others, previously established that chlamydial GI tropism is mediated by distinct chromosomal and plasmid factors. In this study, we describe a genital infection-attenuated Chlamydia muridarum mutant (GIAM-1) that is profoundly and specifically attenuated in the murine genital tract. GIAM-1 infected the murine GI tract similarly to wild-type (WT) Chlamydia muridarum but did not productively infect the lower genital tract of female mice, ascend to infect the upper genital tract, or cause hydrosalpinx. However, GI infection of mice with GIAM-1 elicited a transmucosal immune response that protected against subsequent genital challenge with WT Chlamydia muridarum Collectively, our results demonstrate that chlamydia mutants that are profoundly attenuated for specific organ tissues can be derived and demonstrate that live-attenuated vaccine strains that infect the GI tract, but do not elicit genital tract disease, could be used to protect against chlamydia genital tract infection and disease.IMPORTANCE Chlamydia is the most common sexually transmitted bacterial infection in the United States. Most chlamydia genital infections resolve without serious consequences; however, untreated infection in women can cause pelvic inflammatory disease and infertility. Antibiotics are very effective in treating chlamydia, but most genital infections in both men and women are asymptomatic and go undiagnosed. Therefore, there is a critical need for an effective vaccine. In this work, we show that a mutant chlamydia strain, having substantially reduced virulence for genital infection, colonizes the gastrointestinal tract and produces robust immunity to genital challenge with fully virulent wild-type chlamydia. These results are an important advance in understanding chlamydial virulence and provide compelling evidence that safe and effective live-attenuated chlamydia vaccines may be feasible.

Abstract
OBJECTIVES Sexually transmitted infections (STIs) may present with oropharyngeal or anorectal symptoms. Little is known about the evaluation of adolescents with these complaints in the pediatric emergency department (PED). This study aimed to determine the frequency of and factors associated with STI consideration and testing in this population. METHODS Retrospective chart review of patients aged 13 to 18 years who presented to an urban PED with oropharyngeal or anorectal chief complaints between June 2014 and May 2015. Sexually transmitted infection consideration was defined as sexual history documentation, documentation of STI in differential diagnosis, and/or diagnostic testing. Multivariate logistic regression models were used to identify factors associated with consideration. RESULTS Of 767 visits for oropharyngeal (89.4%), anorectal (10.4%), or both complaints, 153 (19.9%) had STI consideration. Of the 35 visits (4.6%) that included gonorrhea and/or chlamydia testing, 12 (34.3%) included testing at the anatomic site of complaint. Of those 12 tests, 50.0% were the incorrect test. Patients with older age (adjusted odds ratio [aOR] = 1.5, 95% confidence interval [CI] = 1.3-1.7), female sex (aOR = 1.6, 95% CI = 1.03-2.5), or anorectal complaints (aOR = 2.4, 95% CI = 1.3-4.3) were more likely to have STI consideration. CONCLUSIONS In an urban PED, only 20% of visits for adolescents with oropharyngeal or anorectal symptoms included STI consideration. Testing was performed in only 5% of cases and often at an inappropriate anatomic site or with the incorrect test. Interventions to increase awareness of appropriate STI consideration and testing for individuals presenting with possible extragenital complaints may help reduce STIs among adolescents.

Abstract
INTRODUCTION Gonorrhoea and chlamydia cases have been rising among gay, bisexual and other men who have sex with men (MSM) over the last decade. The majority of cases are extragenital and occur at the oropharynx and anorectum. The aim of this narrative review was to review the risk factors and mode of transmission for gonorrhoea and chlamydia at the oropharynx and anorectum among MSM. RESULTS AND DISCUSSION New evidence suggests that oropharyngeal gonorrhoea can be transmitted by kissing in addition to through the established route of condomless oral sex; and anorectal gonorrhoea can be acquired when saliva is used as a lubricant for anal sex and rimming in addition to the established route of condomless penile-anal sex in MSM. In contrast, condomless penile-anal sex remains the major route for chlamydia transmission. CONCLUSIONS Substantial transmission of gonorrhoea may occur with practices other than the established routes of condomless oral and/or anal sex and hence condoms may not be effective in preventing gonorrhoea transmission to extragenital sites. In contrast, condoms are effective for chlamydia control because it is mainly transmitted through condomless penile-anal sex. Novel interventions for gonorrhoea that reduce the risk of transmission at extragenital site are required.

Abstract
Background Most studies evaluating extragenital testing performance for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) detection by the Xpert® CT/NG show high per cent agreement with comparison assays; however, the precision around positive per cent agreement is low and thus the values that have been reported are not highly informative. Therefore, a systematic review was conducted and data from five studies were combined to better assess positive per cent agreement. METHODS The literature indexed on PubMed.gov was searched. Included studies were those that were an evaluation of the Xpert CT/NG assay with rectal and/or pharyngeal specimen types compared with another nucleic acid amplification test (NAAT), the Aptima transcription mediated amplification assay. A full Bayesian method was used for bivariate fixed-effect meta-analysis of positive and negative per cent agreement and pooled estimates (and 95% confidence intervals (CI)) were presented for each. RESULTS The pooled positive and negative per cent agreement for detection of CT in rectal specimens was 89.72% (95% CI: 84.97%, 93.64%) and 99.23% (95% CI: 98.74%, 99.60%), and in pharyngeal specimens, they were 89.96% (95% CI: 66.38%, 99.72%) and 99.62% (95% CI: 98.95%, 99.95%) respectively. For NG detection in rectal specimens, the pooled positive and negative per cent agreement was 92.75% (95% CI: 87.91%, 96.46%) and 99.75% (95% CI: 99.46%, 99.93%), and in pharyngeal specimens, they were 92.51% (95% CI: 85.84%, 97.18%) and 98.56% (95% CI: 97.69%, 99.23%) respectively. CONCLUSIONS It was found that the Xpert CT/NG assay performed similarly to the Aptima transcription mediated amplification assay for the detection of CT and NG in extragenital specimens. The Xpert assay has the benefit of providing faster results at the point-of-care, thus reducing the turnaround time for results, potentially enabling same-day treatment.

Abstract
OBJECTIVES There has been considerable discussion about anorectal Chlamydia trachomatis (CT) in women, with some calling for anorectal CT screening, but little about anorectal Neisseria gonorrhoeae (NG). Given that urogenital NG is more strongly associated with pelvic inflammatory disease, this is an evidence gap. This systematic review and meta-analysis investigates the associations between anorectal CT in women and CT positivity at other sites (urogenital/oropharyngeal) and with anal intercourse, and compares these with anorectal NG within the same study populations. METHODS Electronic databases were searched for English-language studies published to October 2018 using the following terms: ("Chlamydia" OR "Chlamydia trachomatis") AND (("anal" OR "rect*" OR "anorect*") OR ("extra?genital" OR "multi?site")). Studies were included if anorectal NG data were available. Random-effects meta-analyses calculated pooled estimates; heterogeneity was investigated using meta-regression. RESULTS 25 studies were eligible. Anorectal CT positivity ranged from 0% to 17.5%, with a summary estimate of 8.0% (95% CI 7.0 to 9.1; I2=88.5%). Anorectal NG positivity ranged from 0% to 17.0%, with a summary estimate of 2.1% (95% CI 1.6 to 2.8; I2=92.7%). The association between urogenital and anorectal positivity was stronger for NG than CT (summary prevalence ratio (PR)=89.3 (95% CI 53.1 to 150.3; I2=80.1%), PR=32.2 (95% CI 25.6 to 40.7; I2=70.3%), respectively), and between oropharyngeal and anorectal positivity it was stronger for NG than CT (PR=34.8 (95% CI 10.2 to 118.2; I2=89.9%), PR=8.8 (95% CI 6.8 to 11.5; I2=58.1%), respectively). Anal intercourse was associated with anorectal NG (PR=4.3; 95% CI 2.2 to 8.6; I2=0.0%) but not with anorectal CT (PR=1.0; 95% CI 0.7 to 1.4; I2=0.0%). CONCLUSIONS Anorectal CT is more common than anorectal NG, but anorectal NG is more strongly associated with anal intercourse, urogenital and oropharyngeal NG, suggesting that ongoing discussion about anorectal CT should also include NG. Longitudinal data are required to further understanding of the aetiology of anorectal STIs and assess whether anorectal screening is needed in women. TRIAL REGISTRATION NUMBER CRD42df017080188.

Abstract
Gonococcal infection is a current public health problem worldwide, being the second most prevalent bacterial sexually transmitted infection. The etiologic agent is Neisseria gonorrhoeae, a gram-negative diplococcus, and mainly causes urethritis in men. In women up to 50% of infections can be asymptomatic. N. gonorrhoeae has a great ability to develop antibiotic resistance, so the last remaining therapeutic option are extended spectrum cephalosporins. Many guides recommend dual therapy with ceftriaxone and azithromycin, but in recent years the resistance to azithromycin is also increasing, so that dual treatment is being questioned by scientific societies.

Abstract
BACKGROUND Chlamydia trachomatis can lead to a persistent infection in the lower gastrointestinal tract, suggesting a potential role of autoinoculation of cervical chlamydial infection from the rectal site, contributing to repeat infections. Moreover, around 75% of women with urogenital C. trachomatis have concurrent anorectal infection. Current treatment guidelines for urogenital C. trachomatis infection recommend either a single 1 g dose of azithromycin or doxycycline 100 mg twice daily for 7 days. Doxycycline appears to be more effective in treating anorectal infections as suggested in a population of men who have sex with men, but no randomized controlled trial (RCT) had directly compared azithromycin with doxycycline for the treatment of rectal infections. We propose an open-label RCT to compare the microbial cure obtained with a single 1 g dose of azithromycin versus 100 mg of doxycycline twice daily for 7 days, for the treatment of anorectal C. trachomatis infection concurrent to urogenital infection in women. METHODS AND STUDY DESIGN A total of 460 women with C. trachomatis urogenital infection will be enrolled in the study. Women will be asked to provide self-collected anorectal swabs and will be randomized to receive either a 1 g single dose of azithromycin or doxycycline 100 mg twice daily for 7 days. Clinical and biological data will be collected and patients will complete questionnaires about their sexual behavior. The primary outcome is the microbial cure rate, defined as a C. trachomatis negative nucleic acid amplification test (NAAT) result in the anorectal specimens 6 weeks after treatment initiation among women with a C. trachomatis positive urogenital and anorectal NAAT result at the baseline. The secondary outcome is autoinoculation from the rectum to the vagina, which will be evaluated based on the number of women with the same C. trachomatis genotype profile that will be identified in an anorectal-positive specimen obtained 6 weeks after treatment initiation and in a vaginal-positive specimen obtained four months after treatment. DISCUSSION The results of this trial will establish which treatment is more efficacious against anorectal infection and could affect recommendations for the treatment of urogenital C. trachomatis infection, taking into account concurrent anorectal infection.

Prevalence of chlamydia trachomatis infection among reproductive age women in sub Saharan Africa: a systematic review and meta-analysis. BMC Infect Dis 2018; 18:596. [PMID: 30477441 PMCID: PMC6258386 DOI: 10.1186/s12879-018-3477-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2017] [Accepted: 10/31/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Chlamydia trachomatis is the most common curable sexual transmitted bacterial infection in the world, including Sub-Saharan Africa. There is nil systematic review and meta-analysis on Chlamydia trachomatis infection in Sub-Saharan Africa among reproductive age women. Therefore, this study was carried out to determine the pooled prevalence of chlamydia trachomatis infection in Sub-Saharan Africa among reproductive age women. METHODS A comprehensive literature search was conducted from biomedical data bases: Medline, PubMed, EMBASE, Google scholar, HINARI and Cochrane Library using a special index search terms (medical subject headings (MeSH), title and abstract. The Cochrane Q test and I2 statistics was used to test heterogeneity and publication bias was assessed using Begg's and Egger's tests. Results were presented in tables, figures and funnel plot. Data were pooled in a meta-analysis using a random effects model. RESULTS Twenty-four studies were included in this meta-analysis. There was a high level of heterogeneity among studies. The pooled prevalence of Chlamydia trachomatis infection in Sub-Saharan Africa among reproductive age women was 7.8% (95% CI: 5.6-10.6). CONCLUSION This review showed that Chlamydia trachomatis infection is high in Sub-Saharan Africa among reproductive age group women. This evidence suggests that governmental and non-governmental organization shall give attention for primary prevention of this infection. Likewise, in resource limited countries policy makers, stakeholders and health care providers' due attention for Chlamydia trachomatis specific and rapid diagnostic test, treatment in any medical out and in patient clinics for reproductive age women.

Abstract
OBJECTIVE The aim of this study was to describe the use of a nucleic acid amplification test in detecting genital and extragenital Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) in children and adolescents assessed for sexual abuse/assault. METHODS The charts of children aged 0 to 17 years, consecutively evaluated for sexual victimization, in emergency department and outpatient settings were reviewed. Data extracted included age, sex, type of sexual contact, anogenital findings, previous sexual contact, toxicology results, and sites tested for NG and CT. RESULTS Of the 1319 patients who were tested, 579 were tested at more than 1 site, and 120 had at least 1 infected site. Chlamydia trachomatis was identified in 104 patients, and NG was found in 33. In bivariate analysis, a positive test was associated with female sex, age older than 11 years, previous sexual contact, acute or healed genital injury, drug/alcohol intoxication, and examination within 72 hours of sexual contact. Fifty-one patients had positive anal tests, and 24 had positive oral tests. More than 75% of patients with positive extragenital tests had additional positive tests or anogenital injury. Most with a positive anal (59%) or oral (77%) test did not report that the assailant's genitals came into contact with that site. CONCLUSIONS Positive tests for NG and CT in patients evaluated for sexual victimization may represent infection from sexual contact, contiguous spread of infection, or the presence of infected assailant secretions. Relying on patient reports of symptoms, or types of sexual contact, to determine need for testing may miss NG and CT infections in patients evaluated for sexual victimization.

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
Most sexually abused children will not have signs of genital or anal injury, especially when examined nonacutely. A recent study reported that only 2.2% (26 of 1160) of sexually abused girls examined nonacutely had diagnostic physical findings, whereas among those examined acutely, the prevalence of injuries was 21.4% (73 of 340). It is important for health care professionals who examine children who might have been sexually abused to be able to recognize and interpret any physical signs or laboratory results that might be found. In this review we summarize new data and recommendations concerning documentation of medical examinations, testing for sexually transmitted infections, interpretation of lesions caused by human papillomavirus and herpes simplex virus in children, and interpretation of physical examination findings. Updates to a table listing an approach to the interpretation of medical findings is presented, and reasons for changes are discussed.

Abstract
OBJECTIVE To assess chlamydia knowledge, willingness to undertake pharmacy-based chlamydia testing, and facilitators and barriers to such testing in consumers and community pharmacists, in Australia (AUS) and Switzerland (CH). METHODS Statements of interest were retrieved from literature and assembled into a 12-item online survey (English and German versions). Survey was disseminated through Facebook, pharmacies' publicly available emails and professional websites (March 2015). RESULTS Consumers and pharmacists (AUS: ncons = 198, npharm = 162; CH: ncons = 209, npharm = 223) were predominantly female (>65%). Mean chlamydia knowledge scores (maximum of 8) were higher in Australia in consumers (AUS: 6.8 ± 1.5 vs CH: 4.2 ± 2.4; p < 0.001) and in pharmacists (AUS: 7.1 ± 1.1 vs CH: 6.1 ± 1.4; p < 0.001). High willingness of consumers to seek testing (AUS: 79.3% vs CH: 83.3%, p = 0.3) and of pharmacists to provide testing (AUS: 95.7% vs CH: 80.3%, p < 0.001) was observed. Greatest barrier for consumers was "Embarrassed about asking for a test" (AUS: 47.8% vs CH: 51.2%, p = 0.7) and "No remuneration" for pharmacists (AUS: 40.7% vs CH: 31.8%, p = 0.07). CONCLUSION The majority of consumers and pharmacists support pharmacy-based chlamydia testing. There is now emerging evidence that the policy makers in Australia and Switzerland need to develop pharmacy-based chlamydia testing as core business.

Abstract
Chlamydia trachomatis and Neisseria gonorrhoeae constitute major public health problems among women, but the burden of infection in sub-Saharan Africa is poorly documented. We conducted a structured review of the prevalence and incidence of genital, oral and anal C. trachomatis and N. gonorrhoeae infection in women in sub-Saharan Africa. We searched Medline, EMBASE and Web of Science over a 10-year period for studies on epidemiology of genital, oral and anal chlamydial infection and gonorrhoea in women in all countries of sub-Saharan Africa. We assessed geographic and demographic differences in prevalence and incidence of infection; weighted mean prevalence estimates were calculated with a random-effect model. A total of 102 study results were included, with data available for 24/49 of sub-Saharan countries. The weighted prevalence of chlamydial infection was lower among women in community-based studies (3.9%; 95% CI: 2.9-5.1%) than for women recruited at primary healthcare facilities (6.0%; 95% CI: 4.2-8.4%, p < 0.001); the same was observed for gonorrhoea (2.2%; 95% CI: 1.2-4.0% vs. 4.2%; 95% CI: 3.2-5.6%, p < 0.001). Prevalence of Chlamydia among sex workers was 5.5% (95% CI: 4.2-7.3%) and gonorrhoea 7.6% (95% CI: 5.4-11%). Seven studies reported on incidence which varied between 0.75-28 and 2.8-17 per 100 person-years-at-risk for chlamydial infection and gonorrhoea, respectively. Only two studies reported on anal infections and one on oral infection. This overview underscores the considerable incidence and prevalence of genital C. trachomatis and N. gonorrhoeae in women in different settings in sub-Saharan Africa. Better control strategies are warranted to reduce the burden of infection and to prevent long-term complications of these infections.

Abstract
The number of women under community supervision in the United States has increased, and this population has a high risk for sexually transmitted infections (STIs). We examined STI prevalence and multiple risk factors among drug-involved women under community supervision in New York City. Data were from a randomized controlled trial testing the efficacy of a behavioral HIV/STI intervention (Women on the Road to Health [WORTH]) among drug-involved women in the community corrections system in New York City from 2009 to 2012. To be eligible for inclusion, women had to be under community supervision within the past 90 days, have used illicit drugs at least once in the past six months, and have unprotected sex at least once in the past 90 days. Participants completed a survey containing items on STI risk factors and were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Multivariable regression was used to examine associations between risk factors and STI diagnosis. Of 333 women tested, 89 (26.7%) tested positive for an STI. Ten (3.0%) were positive for C. trachomatis, 4 (1.2%) for N. gonorrhoeae, and 77 (23.1%) for T. vaginalis. Women with any STI were more likely to be black (AOR: 2.02; 95% CI: 1.08-3.77), homeless in the past 90 days (AOR: 2.07; 95% CI: 1.01-4.26), arrested in the past 90 days (AOR: 1.97; 95% CI: 1.14-3.39), and have a greater number of sexual partners in the past 90 days (AOR: 1.24; 95% CI: 1.08-1.42). Drug-using women under community supervision have a high burden of STIs driven by multiple risk factors. Implementing STI screening, prevention, and treatment programs in community supervision settings could facilitate a reduction in STIs among this population.

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
Nucleic acid amplification testing (NAAT) is the preferred method to detect Chlamydia trachomatis and Neisseria gonorrhoeae, but no commercial tests are cleared by the U.S. Food and Drug Administration for use with extragenital swab samples. This study evaluated the performance of the Gen-Probe Aptima Combo2 assay (Aptima) and the Cepheid Xpert CT/NG assay (Xpert) to detect C. trachomatis and N. gonorrhoeae in rectal and pharyngeal samples from 224 men and 175 women reporting a history of anal receptive sexual intercourse. Discordant results between the NAATs were repeated using the assays APTIMA CT or APTIMA GC, which target alternate primers, as the confirmatory tests. C. trachomatis was detected from 59 rectal swabs and 8 pharyngeal samples, with 97.7% and 99.5% agreement between the two test systems, respectively. For C. trachomatis, Xpert was 95% sensitive (95% CI, 86 to 99%) and Aptima was 92% sensitive (95% CI, 81 to 97%) from rectal swabs, while both systems were 100% sensitive from pharyngeal samples. N. gonorrhoeae was detected from 30 rectal and 40 pharyngeal samples, with 99.5% and 97.5% agreement between the two test systems. The sensitivity of Xpert for N. gonorrhoeae from rectal swabs was 100% (95% CI, 88 to 100%) versus 93% (95% CI, 78 to 99%) for Aptima. From pharyngeal swab samples, Xpert was 98% sensitive (95% CI, 87 to 99.9%) versus 93% (95% CI, 80 to 98%) for Aptima. For C. trachomatis, neither system was >95% sensitive from the rectum, though both were >99.5% specific. For N. gonorrhoeae, Xpert had higher sensitivity than Aptima, but with more false positives from pharyngeal samples.

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 Screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) in men who have sex with men is risk based. Despite high frequencies of oral and receptive anal intercourse (RAI) among women, extragenital screening is not recommended. METHODS Women (n = 175) and men who have sex with men (n = 224) primarily recruited from a sexually transmitted infection clinic reporting a lifetime history of RAI completed a structured questionnaire and clinician-collected swab samples from the rectum, pharynx, vagina (women), and urine (men). CT and GC were detected using 2 commercial nucleic acid amplification tests (Aptima Combo 2; Hologic, Inc, Bedford, MA; Xpert CT/NG, Cepheid Innovation, Sunnyvale, CA). RESULTS The median age of the population was 26 years, 62% were white, and 88% were enrolled from a sexually transmitted disease clinic. Men were more likely than women to have GC (22.8% vs. 3.4%) and CT (21.9% vs. 12.6%). In men versus women, GC was detected in 16.5% versus 2.3% of pharyngeal swabs, 11.6% versus 2.3% of rectal swabs, and 5.4% versus 2.9% of urine samples or vaginal swabs. C. trachomatis was detected in 2.2% versus 1.7% of pharyngeal swabs, 17.4% versus 11.4% of rectal swabs, and 4.5% versus 10.3% for urogenital sites in men versus women. Overall 79.6% of CT and 76.5% of GC in men and 18.2% of CT and 16.7% of GC in women were detected only in the pharynx or rectum. CONCLUSION Reliance on urogenital screening alone misses most of GC and CT in men and more than 15% of infections in women reporting RAI.

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
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.

Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections detected by real-time PCR among individuals reporting sexual assaults in the Paris, France area. Forensic Sci Int 2016; 266:130-133. [PMID: 27261924 DOI: 10.1016/j.forsciint.2016.04.031] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2015] [Revised: 02/04/2016] [Accepted: 04/26/2016] [Indexed: 11/29/2022]
Abstract
BACKGROUND Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) are the most common bacteria involved in sexually transmitted infections (STIs). In France, combined screening for CT and NG using nucleic acid amplification tests is recommended in populations that are considered at risk. However, no data have been published about victims of sexual assaults. The aim of this retrospective study was to assess the usefulness of real-time PCR for the rapid detection of CT and NG genomic DNA, and the prevalence of CT/NG infections in a sample of sexual assault victims examined at a department of forensic medicine. METHODS Between July 2012 and July 2013, 326 adults and adolescents aged over 12 years reported a sexual assault and they were referred to the Department of Forensic Medicine for a medical and forensic examination. Secretions from urogenital (cervix or vagina), anorectal, or pharyngeal sites were collected for CT/NG assays. RESULTS CT and NG were detected in 48/326 (15%) and 16/326 patients (5%), respectively, where 10 (3%) had a CT/NG co-infection. Among 48 patients with CT infection, 13 (27.1%) patients had co-occurring genital and anorectal infections. For the pharyngeal sites, 3/21 men (14.3%) were NG-positive. CONCLUSIONS Given the high prevalence of CT and NG infections, systematic screening of both pathogens at the time of forensic examination should provide an opportunity for the early treatment of diagnosed STIs.

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.

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.

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. [PMID: 26513479 PMCID: PMC4626043 DOI: 10.1371/journal.pone.0140297] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2015] [Accepted: 09/23/2015] [Indexed: 11/19/2022] Open
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.

Neisseria gonorrhoeae and Chlamydia trachomatis among women reporting extragenital exposures. Sex Transm Dis 2015; 42:233-9.

Abstract
BACKGROUND The Centers for Disease Control and Prevention recommends pharyngeal screening of Neisseria gonorrhoeae (GC) and rectal screening of GC and Chlamydia trachomatis (CT) in HIV-infected and at-risk men who have sex with men (MSM). There are currently no recommendations to routinely screen women at extragenital sites. We define the prevalence of extragenital GC and CT in women attending 2 urban sexually transmitted disease clinics in Baltimore City and compare it with the prevalence of extragenital infections in MSM and men who have sex with women. METHODS All patients who reported extragenital exposures in the preceding 3 months, who presented for care between June 1, 2011, and May 31, 2013, and who were tested for GC and CT using nucleic acid amplification tests at all sites of exposure were included in the analyses. We used logistic regression models to identify risk factors for extragenital infections. RESULTS A total of 10,389 patients were included in this analysis (88% African American; mean age, 29 years; 42% women; 7% MSM; 2.5% HIV infected). The prevalence estimates of any extragenital GC and CT were as follows: 2.4% GC and 3.7% CT in women, 2.6% GC and 1.6% CT in men who have sex with women, and 18.9% GC and 11.8% CT in MSM. Among women, 30.3% of GC infections and 13.8% of CT infections would have been missed with urogenital-only testing. Unlike MSM, age ≤ 18 years was the strongest predictor of extragenital infections in women. CONCLUSIONS Although the prevalence of extragenital gonorrhea and chlamydia is highest in MSM, a significant number of GC and CT infections in young women would be missed with genital-only testing. Cost-effectiveness analyses are needed to help inform national guidelines on extragenital screening in young women.

Abstract
Recent data suggest that azithromycin may not be as effective as doxycycline in eradication of genital chlamydial infection. The aim of this study was to compare the eradication rate of pharyngeal Chlamydia trachomatis infection after treatment with azithromycin 1 g stat with that of doxycycline 100 mg twice a day for seven days. A prospective open-label observational study was conducted on patients with pharyngeal Chlamydia trachomatis diagnosed at Whittall Street Clinic, University Hospitals Birmingham, Birmingham, UK, between July 2012 and July 2013. We confirmed eradication of pharyngeal Chlamydia trachomatis with a negative test of cure. We treated all our patients with azithromycin 1 g stat until February 2013. At that stage, we offered doxycycline to patients with pharyngeal Chlamydia trachomatis A total of 398 patients (52 men, 346 women) were diagnosed with pharyngeal Chlamydia trachomatis during the study period. Of the 172 patients included in the final analysis, 78 were treated with azithromycin and 64 with doxycycline. Treatment failure was identified among 8/78 (10%) patients treated with azithromycin and 1/64 (2%) treated with doxycycline (absolute difference: 8 percentage points, 95% CI: 0-17%, p = 0.041). In our study, doxycycline 100 mg twice a day for seven days was associated with less treatment failure of oropharyngeal chlamydia compared with azithromycin 1 g stat Future randomised studies should investigate whether patients with pharyngeal Chlamydia trachomatis should be followed up with a test of cure when treated with azithromycin, or be treated with doxycycline.

Abstract
BACKGROUND Epidemiological data of genital chlamydia and gonorrhea, required to inform design and implementation of control programs, are limited for rural Africa. There are no data on the prevalence of rectal or pharyngeal infections among African women. METHODS A cross-sectional study of 604 adult women visiting 25 primary health care facilities in rural South Africa was conducted. Vaginal, anorectal, and oropharyngeal swabs were tested for Chlamydia trachomatis and Neisseria gonorrhoeae. RESULTS Prevalence of genital chlamydia was 16% and that of gonorrhea was 10%; rectal chlamydial infection was diagnosed in 7.1% and gonococcal in 2.5% of women. One woman had pharyngeal chlamydia. Most women with genital chlamydia (61%) and gonorrhea (57%) were asymptomatic. Independent risk factors for genital chlamydia were younger age (adjusted odds ratio [aOR], 0.96 per year; 95% confidence interval [CI], 0.93-0.98), hormonal contraceptive use (aOR, 2.2; 95% CI, 1.3-3.7), pregnancy (aOR, 2.4; 95% CI, 1.3-4.4), and intravaginal cleansing (aOR, 1.7; 95% CI, 1.04-2.8). Intravaginal cleansing was associated with genital gonorrhea (aOR, 1.9; 95% CI, 1.1-3.3). CONCLUSIONS Genital and rectal, but not pharyngeal, chlamydia and gonorrhea are highly prevalent and frequently asymptomatic in women in rural South Africa. Young women attending health care facilities for antenatal care or family planning should be prioritized in control efforts.

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.

Abstract
PURPOSE OF REVIEW The proportion of Neisseria gonorrhoeae isolates with reduced susceptibility to extended-spectrum cephalosporins (ESCs) has increased rapidly since 2006. Clinicians, researchers, and public health officials need to be prepared for the possibility of an era of untreatable gonorrhea. This review focuses on the evidence for current gonorrhea treatment recommendations, potential future treatment options, and other methods to control gonorrhea. RECENT FINDINGS In addition to an increase in isolates with decreased susceptibility to ESCs, there have been reported treatment failures to both cefixime and ceftriaxone. In response, some countries have increased the recommended cephalosporin dose, and most now recommend dual therapy with an ESC and azithromycin. The pharynx has been implicated as a site for acquiring resistance through transformation with commensal Neisseria species or induced resistance through subtherapeutic antimicrobial levels. Thus, appropriate screening of the pharynx and treatment with a regimen that eradicates gonorrhea from the pharynx is necessary. At present, several studies are evaluating various novel treatment regimens in preparation for an era of untreatable gonorrhea. SUMMARY Screening for asymptomatic infections, maintaining culture capacity to monitor antimicrobial resistance, treating with ceftriaxone and azithromycin, and ensuring that all sexual partners are treated are among the best strategies to control gonorrhea in the current clime.

Abstract
Aim: The overall aim of this paper is to examine sexually active young people’s behavioral expectations of condom use. Methods: We collected data at nine youth clinics and one sexually transmitted infections (STI) clinic in Sweden. We included participants whom had been sexually active during the past 12 months: A total of 1022 participants between the ages of 15 and 31 were included. We analyzed the data separately, for different types of sexual practices and types of sexual partners. Multinomial logistic regression was used to analyze age and gender differences for discrepancies. Results: The behavioral expectation of condom use differed, depending on the type of sexual practice and the type of partner. For all types of sex, the overall pattern showed that the participants were most likely to use a condom with a casual unknown partner, followed by a casual known partner, regular partner and lastly, a main partner. Our results also demonstrated that there is a discrepancy between the behavioral expectation of condom use and the self-reported condom use. The lowest discrepancy was for oral sex, especially with a main partner, and the largest discrepancy was for anal sex and vaginal sex with a casual partner. Conclusions: Our results imply that the participants had a greater expectation of condom use than actually occurs, especially for casual unknown partners. There is a lack of knowledge about the risks associated with oral sex, which is evident in the results of the participants’ behavioral expectations of condom use under those conditions.

Abstract
OBJECTIVES Pharyngeal Chlamydia trachomatis (chlamydia) might contribute to ongoing chlamydia transmission, yet data on spontaneous clearance duration are rare. We examined the prevalence, spontaneous clearance, chlamydial DNA concentration and genotypes of pharyngeal chlamydia among clinic patients with sexually transmitted infection (STI). METHODS Female patients at high risk for an STI who reported active oral sex and male patients who have sex with men (MSM) were screened for pharyngeal chlamydia RNA using a nucleic acid amplification test. A repeat swab was obtained to evaluate spontaneous clearance in untreated patients with pharyngeal chlamydia. Quantitative chlamydia DNA load was determined by calculating the chlamydia/human cell ratio. RESULTS Pharyngeal chlamydia was detected in 148/13 111 (1.1%) MSM and in 160/6915 (2.3%) women. 53% of MSM and 32% of women with pharyngeal chlamydia did not have a concurrent anogenital chlamydia infection. In 16/43 (37%) MSM and in 20/55 (36%) women, the repeat pharyngeal swab was negative (median follow-up 10 days, range 4-58 days). Patients with an initial chlamydial DNA concentration above the median were less likely to clear. Of 23 MSM with pharyngeal chlamydia who had sex with a lymphogranuloma venereum (LGV)-positive partner recently or in the past, two were LGV biovar positive (8.7%). CONCLUSIONS The pharynx is a reservoir for chlamydia and LGV, and may play a role in ongoing transmission. Although delay in ribosomal RNA decline after resolution of the infection might have led to an underestimation of spontaneous clearance, in high-risk STI clinic patients, testing the pharynx for chlamydia should be considered.

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.

High co-occurrence of anorectal chlamydia with urogenital chlamydia in women visiting an STI clinic revealed by routine universal testing in an observational study; a recommendation towards a better anorectal chlamydia control in women. BMC Infect Dis 2014; 14:274. [PMID: 24885306 PMCID: PMC4032161 DOI: 10.1186/1471-2334-14-274] [Citation(s) in RCA: 61] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2014] [Accepted: 05/02/2014] [Indexed: 01/10/2023] Open
Abstract
Background Symptom- and sexual history-based testing i.e., testing on indication, for anorectal sexually transmitted infections (STIs) in women is common. Yet, it is unknown whether this strategy is effective. Moreover, little is known about alternative transmission routes i.e. by fingers/toys. This study assesses anorectal STI prevalence and infections missed by current testing practice, thereby informing the optimal control strategy for anorectal STIs in women. Methods Women (n = 663) attending our STI-clinic between May 2012-July 2013 were offered routine testing for anorectal and urogenital Chlamydia trachomatis and Neisseria gonorrhoeae. Data were collected on demographics, sexual behaviour and symptoms. Women were assigned to one of the categories: indication (reported anal sex/symptoms), fingers/toys (only reported use of fingers/toys), or without indication. Results Of women, 92% (n = 654) participated. There were 203 reports (31.0%) of anal sex and/or symptoms (indication), 48 reports (7.3%) of only using fingers/toys (fingers/toys), and 403 reports (61.6%) of no anal symptoms, no anal sex and no anal use of fingers/toys (without indication). The overall prevalence was 11.2% (73/654) for urogenital chlamydia and 8.4% (55/654) for anorectal chlamydia. Gonorrhoea infections were not observed. Prevalence of anorectal chlamydia was 7.9% (16/203) for women with indication and 8.6% (39/451) for all other women (P = 0.74). Two-thirds (39/55) of anorectal infections were diagnosed in women without indication. Isolated anorectal chlamydia was rare (n = 3): of all women with an anorectal infection, 94.5% (52/55) also had co-occurrence of urogenital chlamydia. Of all women with urogenital chlamydia, 71.2% (52/73) also had anorectal chlamydia. Conclusions Current selective testing on indication of symptoms and sexual history is not an appropriate control strategy for anorectal chlamydia in women visiting an STI clinic. Routine universal anorectal testing is feasible and may be a possible control strategy in women. Yet costs may be a problem. When more restricted control measures are preferred, possible alternatives include (1) anorectal testing only in women with urogenital chlamydia (problem: treatment delay or loss to follow up), and (2) direct treatment for urogenital chlamydia that is effective for anorectal chlamydia as well.

Abstract
Gonorrhoea is a major public health concern globally. Of particularly grave concern is that resistance to the extended-spectrum cephalosporins has emerged during the most recent years. This guideline provides recommendations regarding the diagnosis and treatment of gonorrhoea in Europe. Compared to the outdated 2009 European gonorrhoea guideline, this 2012 European gonorrhoea guideline provides up-to-date guidance on, broader indications for testing and treatment of gonorrhoea;the introduction of dual antimicrobial therapy (ceftriaxone 500 mg and azithromycin 2 g) for uncomplicated gonorrhoea when the antimicrobial sensitivity is unknown; recommendation of test of cure in all gonorrhoea cases to ensure eradication of infection and identify emerging resistance; and recommendations to identify, verify and report failures with recommended treatment regimens. Optimisations of the testing, diagnostics, antimicrobial treatment and follow-up of gonorrhoea patients are crucial in controlling the emergent spread of cephalosporin-resistant and multidrug-resistant gonorrhoea.
