ABSTRACT
IntroductionA national study from 2006 to 2008 showed a high antibody prevalence of 3.2% against hepatitis C virus (HCV) in Romania, but more recent epidemiological data on hepatitis C prevalence are lacking.AimWe aimed to estimate the current prevalence of HCV antibodies (anti-HCV) and chronic HCV infection in the general adult population in Romania, as a crucial element in monitoring progress towards eliminating hepatitis C.MethodsWe used anonymised leftover sera from a SARS-CoV-2 survey conducted between July and October 2020 (n = 2,100), supplemented with sera collected prospectively between July 2022 and March 2023 (n = 574). These included sera collected from adults visiting laboratories for routine medical check-ups. Sera were tested for anti-HCV and HCV core antigen and classified according to anti-HCV and chronic infection status.ResultsOf the total 2,674 specimens tested, 44 were anti-HCV-positive with a weighted anti-HCV prevalence of 1.4% (95%â¯CI: 1.0-1.9), and 29 were HCV core antigen-positive with a weighted prevalence of chronic infection of 0.9% (95%â¯CI: 0.5-1.2). The prevalence of chronic infection did not differ significantly between men and women. It was higher in persons 60 years and older (2.0%; 95%â¯CI: 1.1-3.0) and in specimens from the North-East region (2.2%; 95%â¯CI: 0.8-3.7).ConclusionAlthough the overall HCV prevalence in Romania is currently low, targeted screening, prevention measures and treatment scale-up are needed especially for the population 60 years and older and in the north-eastern part of the country to achieve the goal of ending the hepatitis C epidemic.

IntroductionObtaining epidemiological data on chronic hepatitis C virus (HCV) infection is essential to monitor progress towards the hepatitis C elimination targets.AimWe aimed to estimate the prevalence of chronic HCV and the seroprevalence of HCV in the adult general population in Estonia.MethodsThis cross-sectional study, conducted between 12 July and 6 December 2022, included anonymised residual sera collected prospectively from patients 18 years and older visiting a general practitioner in all counties of Estonia. Specimens were considered HCV-seropositive if they tested positive for HCV antibodies by enzyme-linked immunoassay, confirmed by line-immunoblot assay. Chronic HCV infection was determined by positive RT-qPCR.ResultsWe tested a total of 4,217 specimens. The estimated HCV seroprevalence and prevalence of chronic HCV infection were 1.8% (95% CI: 1.4-2.2) and 0.8% (95% CI: 0.5-1.1), respectively, with ca 8,100 persons estimated to have chronic HCV infection in the general adult population of Estonia. No statistically significant differences in the prevalence of chronic HCV infection were observed between sexes, counties or age groups, with the highest prevalence rates observed in men (sex ratio: 1.7), Ida-Virumaa County (1.8%; 95% CI: 0.8-3.6) and the age group 40-49 years (1.7%; 95% CI: 0.9-2.9).ConclusionThis study found an overall low prevalence of chronic HCV infection in Estonia. Continued efforts should be made for the targeted screening, diagnosis and treatment of individuals with chronic HCV infection to achieve hepatitis elimination targets.

BACKGROUND: Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is a global health challenge. Limitations to AMR surveillance reporting, alongside reduction in culture-based susceptibility testing, has resulted in a need for rapid diagnostics and strain detection. We investigated Nanopore sequencing time, and depth, to accurately identify closely related N. gonorrhoeae isolates, compared to Illumina sequencing. METHODS: N. gonorrhoeae strains collected from a London sexual health clinic were cultured and sequenced with MiSeq and MinION sequencing platforms. Accuracy was determined by comparing variant calls at 68 nucleotide positions (37 resistance-associated markers). Accuracy at varying MinION sequencing depths was determined through retrospective time-stamped read analysis. RESULTS: Of 22 MinION-MiSeq pairs reaching sufficient sequencing depth, agreement of variant call positions passing quality control criteria was 185/185 (100%; 95% confidence interval [CI], 98.0%-100.0%), 502/503 (99.8%; 95% CI, 98.9%-99.9%), and 564/565 (99.8%; 95% CI, 99.0%-100.0%) at 10x, 30x, and 40x MinION depth, respectively. Isolates identified as closely related by MiSeq, within one yearly evolutionary distance of ≤5 single nucleotide polymorphisms, were accurately identified via MinION. CONCLUSIONS: Nanopore sequencing shows utility as a rapid surveillance tool, identifying closely related N. gonorrhoeae strains, with just 10x sequencing depth, taking a median time of 29 minutes. This highlights its potential for tracking local transmission and AMR markers.

OBJECTIVES: A lactobacilli-dominated vaginal microbiome may protect against pelvic inflammatory disease (PID), but one dominated by Gardnerella species might increase susceptibility. Not all lactobacilli are equally protective. Recent research suggests that D(-) isomer lactic acid producing lactobacilli (Lactobacillus crispatus, Lactobacillus jensenii and Lactobacillus gasseri) may protect against infection with Chlamydia trachomatis, an important cause of PID. Lactobacillus iners , which produces L(+) isomer lactic acid, may be less protective. We investigated the microbiome in stored vaginal samples from participants who did or did not develop PID during the prevention of pelvic infection (POPI) chlamydia screening trial. METHODS: Long-read 16S rRNA gene nanopore sequencing was used on baseline vaginal samples (one per participant) from all 37 women who subsequently developed clinically diagnosed PID during 12-month follow-up, and 111 frequency matched controls who did not, matched on four possible risk factors for PID: age <20 versus ≥20, black ethnicity versus other ethnicity, chlamydia positive versus negative at baseline and ≥2 sexual partners in the previous year versus 0-1 partners. RESULTS: Samples from 106 women (median age 19 years, 40% black ethnicity, 22% chlamydia positive, 54% reporting multiple partners) were suitable for analysis. Three main taxonomic clusters were identified dominated by L. iners, L. crispatus and Gardnerella vaginalis. There was no association between a more diverse, G. vaginalis dominated microbiome and subsequent PID, although increased Shannon diversity was associated with black ethnicity (p=0.002) and bacterial vaginosis (diagnosed by Gram stain p<0.0001). Women who developed PID had similar relative abundance of protective D(-) isomer lactic acid producing lactobacilli to women without PID, but numbers of PID cases were small. CONCLUSIONS: In the first-ever community-based prospective study of PID, there was no clear association between the vaginal microbiome and subsequent development of PID. Future studies using serial samples may identify vaginal microbial communities that may predispose to PID.

OBJECTIVES: Azithromycin treatment of Chlamydia trachomatis (CT) may not be adequate to treat concomitant Mycoplasma genitalium (MG) infection, and particularly if MG has macrolide resistance-associated mutations (MG-MRAMs). We estimated prevalence of coinfections of CT with MG carrying MRAM, and risk factors for MG-MRAM among a sexual health clinic population. STUDY DESIGN AND SETTING: Among symptomatic and STI-contact clinic attendees in London, prevalence of CT-MG coinfection and MG-MRAM were estimated using nucleic acid amplification testing and Sanger sequencing, respectively, and their associated risk factors analysed using logistic regression. RESULTS: MG prevalence was 7.5% (23/307), 17.3% (30/173), and 11.4% (8/70) in females, men who have sex with women (MSW) and men who have sex with men (MSM), respectively; MG coinfection in CT-infected participants represented 28.0% (7/25), 13.5% (5/37), 0.0% (0/0), respectively. Presence of MG-MRAM was 39.1% (9/23) in female swabs, 70.0% (21/30) in MSW urine and 83.3% (5/6) in MSM rectal swabs. In multivariate analyses, coinfection with another STI was strongly associated with MG-MRAM (OR: 7.19; 95% CI: 2.4 to 21.5). CONCLUSION: A significant proportion of participants in our study of symptomatic patients and STI contacts were infected with macrolide-resistant MG, suggesting that testing for MG and MRAM, for MG positives, might be clinically useful. The findings also suggest services explore potential benefits of testing CT positive samples for MG in these patient groups. Where MG testing is not available, potential high rates of MG coinfection should be borne in mind when considering azithromycin in the treatment of CT among STI contacts and symptomatic patients.

OBJECTIVES: To determine if media coverage of an outbreak of high-level azithromycin-resistant Neisseria gonorrhoeae (HL-AziR) impacted online search interest or was temporally associated with health-seeking behaviours in several English cities. METHODS: A descriptive analysis of outbreak-related online media articles and relative search interest (RSI) using Google and an interrupted time series analysis using routine surveillance data from sexual health clinics (SHCs) in England (GUMCAD STI surveillance system). The main outcomes were adjusted incidence rate ratios (IRRs) of weekly attendances, gonorrhoea tests and diagnoses of gonorrhoea or 'any STI' in selected cities after media coverage of the outbreak in 2015 and 2016. RESULTS: RSI for outbreak-related terms peaked during media coverage in September 2015 with smaller peaks coinciding with subsequent coverage. The greatest increase in RSI was in Leeds, which coincided with a 63% rise (n=1932; IRR 1.26, 95% CI 1.12 to 1.43) in SHC attendances by women. There was only a 7% (n=1358; IRR 1.01, 95% CI 0.91 to 1.11) increase in attendances by men. Modest increases in outcomes occurred in four other cities with a high RSI. There was no evidence of increases in outcomes in cities, other than Leeds, after subsequent media coverage of the outbreak. CONCLUSIONS: National and local media coverage of the HL-AziR outbreak coincided with peak RSI for related terms, and a transient increase in attendances, gonorrhoea tests and diagnoses of gonorrhoea or 'any STI' in some cities with a high RSI. Our analysis demonstrates the potential for media coverage to influence health-seeking behaviours during high-profile STI outbreaks.

OBJECTIVES: The size of the population of men who have sex with men (MSM) who may be eligible for HIV pre-exposure prophylaxis (HIV-PrEP) in England remains unknown. To plan for a national PrEP implementation trial, we estimated the number of MSM attending sexual health clinics (SHCs) that may be eligible for HIV-PrEP in England. METHODS: Sexually transmitted infection (STI) surveillance data from 2010 to 2015 from the GUMCAD surveillance system were used to estimate the annual number of HIV-negative MSM who may be eligible for HIV-PrEP in England. Based on national eligibility criteria, we identified HIV-negative MSM attending SHCs with a HIV-negative test in the past year and used diagnosed bacterial STI (past year) in this group as a proxy for condomless sex and eligibility for HIV-PrEP. We estimated HIV incidence per 100 person-years (py) in these groups in 2014. RESULTS: During 2010-2015, the number of HIV-negative MSM attending SHCs with a HIV-negative test in the past year doubled from 14 643 to 29 023, and HIV incidence in this group was 1.9 (95% CI 1.6 to 2.2) per 100 py in 2014. In the same period, the subgroup with a bacterial STI diagnosis (past year), and therefore considered potentially eligible for HIV-PrEP in this analysis, increased from 4365 (30%) to 10 276 (35%). HIV incidence in this subgroup was 3.3 (95% CI 2.7 to 4.0) per 100 py in 2014. CONCLUSIONS: In 2015, approximately 10 000 HIV-negative MSM were considered potentially eligible for HIV-PrEP based on clinic history in GUMCAD. These data were used to inform the initial recruitment target for the PrEP Impact Trial and will inform future evaluations at a population level.

Objectives: To describe trends in prevalence, susceptibility profile and risk factors for MDR Neisseria gonorrhoeae (MDR-NG) in England and Wales. Methods: Isolates from 16â242 gonorrhoea episodes at sexual health clinics within the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) underwent antimicrobial susceptibility testing. MDR-NG was defined as resistance to ceftriaxone, cefixime or azithromycin, plus at least two of penicillin, ciprofloxacin and spectinomycin. Trends in resistance are presented for 2004-15; prevalence and logistic regression analyses for MDR-NG cover the period of the most recent treatment guideline (ceftriaxone plus azithromycin), 2011-15. Results: Between 2004 and 2015, the proportion of N. gonorrhoeae isolates fully susceptible to all antimicrobial classes fell from 80% to 46%, with the proportion resistant to multiple (two or more) classes increasing from 7.3% to 17.5%. In 2011-15, 3.5% of isolates were MDR-NG, most of which were resistant to cefixime (100% in 2011, decreasing to 36.9% in 2015) and/or azithromycin (4.2% in 2011, increasing to 84.3% in 2015). After excluding azithromycin-resistant isolates, modal azithromycin MICs were higher in MDR versus non-MDR isolates (0.5 versus 0.125 mg/L), with similar results for ceftriaxone (modal MICs 0.03 versus ≤0.002 mg/L). After adjustment for confounders, MDR-NG was more common among isolates from heterosexual men, although absolute differences in prevalence were small [4.6% versus 3.3% (MSM) and 2.5% (women)]. Conclusions: N. gonorrhoeae is becoming less susceptible to available antimicrobials. Since 2011, a minority of isolates were MDR-NG; however, MICs of azithromycin or ceftriaxone (first-line therapies) for many of these were elevated. These findings highlight the importance of continued antimicrobial stewardship for gonorrhoea.

OBJECTIVES: Men who have sex with men (MSM) bear a disproportionate burden of STIs. While routine STI surveillance data suggest MSM regularly access specialist genitourinary medicine (GUM) clinics for their sexual healthcare, the extent to which MSM attend non-specialist sexual health services (SHSs) is unclear. METHODS: We used data from the GUM Clinic Activity Data Set (GUMCADv2), the national STI surveillance system, to compare the characteristics, service usage and STI outcomes of MSM accessing specialist and non-specialist (non-GUM) SHSs in England in 2014. Pearson's χ2, Student's t-test and logistic regression analysis were used. RESULTS: Where sexual orientation was recorded (92%), 11% (4552/41â 597) of non-GUM attendances were among MSM compared with 28% (280â 466/999â 331) of GUM attendances (p<0.001). Compared with those attending GUM services, MSM attending non-GUM services were younger (mean age: 30.2â years vs 37.7â years; p<0.001) and were more likely to be of mixed ethnicity (4.9% vs 3.5%; p<0.001), to have had a full sexual health screen (chlamydia, gonorrhoea, syphilis and HIV tests) (48.0% vs 37.0%; p<0.001) and to be diagnosed with chlamydia (7.4% vs 4.1%; p<0.001) and gonorrhoea (8.5% vs 6.5%: p<0.001). MSM attending non-GUM services had slightly lower HIV test uptake (87.0% vs 95.0%; p=0.157) and were less likely to be diagnosed with HIV (0.5% vs 0.8%; p=0.019), compared with those attending GUM clinics. CONCLUSIONS: Non-specialist SHSs play an important role in the care of MSM and should ensure services meet their needs.

OBJECTIVES: It has been suggested that treatment of STIs with azithromycin may facilitate development of azithromycin resistance in Neisseria gonorrhoeae (NG) by exposing the organism to suboptimal doses. We investigated whether treatment history for non-rectal Chlamydia trachomatis (CT), non-gonococcal urethritis (NGU) or NG (proxies for azithromycin exposure) in sexual health (GUM) services was associated with susceptibility of NG to azithromycin. METHODS: Azithromycin susceptibility data from the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP 2013-2015, n=4606) and additional high-level azithromycin-resistant isolates (HL-AziR) identified by the Public Health England reference laboratory (2013-2016, n=54) were matched to electronic patient records in the national GUMCAD STI surveillance dataset (2012-2016). Descriptive and regression analyses were conducted to examine associations between history of previous CT/NGU/NG and subsequent susceptibility of NG to azithromycin. RESULTS: Modal azithromycin minimum inhibitory concentration (MIC) was 0.25 mg/L (one dilution below the resistance breakpoint) in those with and without history of previous CT/NGU/NG (previous 1 month/6 months). There were no differences in MIC distribution by history of CT/NGU (P=0.98) or NG (P=0.85) in the previous 1 month/6 months or in the odds of having an elevated azithromycin MIC (>0.25 mg/L) (Adjusted OR for CT/NGU 0.97 (95% CI 0.76 to 1.25); adjusted OR for NG 0.82 (95% CI: 0.65 to 1.04)) compared with those with no CT/NGU/NG in the previous 6 months. Among patients with HL-AziR NG, 3 (4%) were treated for CT/NGU and 2 (3%) for NG in the previous 6 months, compared with 6% and 8%, respectively for all GRASP patients. CONCLUSIONS: We found no evidence of an association between previous treatment for CT/NGU or NG in GUM services and subsequent presentation with an azithromycin-resistant strain. As many CT diagnoses occur in non-GUM settings, further research is needed to determine whether azithromycin-resistant NG is associated with azithromycin exposure in other settings and for other conditions.

OBJECTIVES: The 1916 Royal Commission on Venereal Diseases was established in response to epidemics of syphilis and gonorrhoea in the UK. In the 100 years since the Venereal Diseases Act (1917), the UK has experienced substantial scientific, economic and demographic changes. We describe historical and recent trends in STIs in the UK. METHODS: We analysed surveillance data derived from STI clinics' statistical returns from 1917 to 2016. RESULTS: Since 1918, gonorrhoea and syphilis diagnoses have fluctuated, reflecting social, economic and technological trends. Following spikes after World Wars I and II, rates declined before re-emerging during the 1960s. At that time, syphilis was more common in men, suggestive of transmission within the men who have sex with men (MSM) population. Behaviour change following the emergence of HIV/AIDS in the 1980s is thought to have facilitated a precipitous decline in diagnoses of both STIs in the mid-1980s. Since the early 2000s, gonorrhoea and syphilis have re-emerged as major public health concerns due to increased transmission among MSM and the spread of antimicrobial-resistant gonorrhoea. Chlamydia and genital warts are now the most commonly diagnosed STIs in the UK and have been the focus of public health interventions, including the national human papillomavirus vaccination programme, which has led to substantial declines in genital warts in young people, and the National Chlamydia Screening Programme in England. Since the 1980s, MSM, black ethnic minorities and young people have experienced the highest STI rates. CONCLUSION: Although diagnoses have fluctuated over the last century, STIs continue to be an important public health concern, often affecting more marginalised groups in society. Prevention must remain a public health priority and, as we enter a new era of sexual healthcare provision including online services, priority must be placed on maintaining prompt access for those at greatest risk of STIs.

OBJECTIVES: To explore the risk factors for, and clinical outcomes in men who have sex with men (MSM) prescribed HIV postexposure prophylaxis following sexual exposure (PEPSE) at sexual health clinics (SHCs) in England. METHODS: National STI surveillance data were extracted from the genitourinary medicine clinic activity dataset (GUMCADv2) for 2011-2014. Quarterly and annual trends in the number of episodes where PEPSE was prescribed were analysed by gender and sexual risk. Risk factors associated with being prescribed PEPSE among MSM attendees were explored using univariable and multivariable logistic regression. Subsequent HIV acquisition from 4â months after initiating PEPSE was assessed using multivariable Cox proportional hazards models, stratified by clinical risk profiles. RESULTS: During 2011-2014, there were 24â 004 episodes where PEPSE was prescribed at SHCs, of which 69% were to MSM. The number of episodes where PEPSE was prescribed to MSM increased from 2383 in 2011 to 5944 in 2014, and from 1384 to 2226 for heterosexual men and women. 15% of MSM attendees received two or more courses of PEPSE. Compared with MSM attendees not prescribed PEPSE, MSM prescribed PEPSE were significantly more likely to have been diagnosed with a bacterial STI in the previous 12â months (adjusted OR (95% CI)-gonorrhoea: 11.6 (10.5 to 12.8); chlamydia: 5.02 (4.46 to 5.67); syphilis: 2.25 (1.73 to 2.93)), and were more likely to subsequently acquire HIV (adjusted HR (aHR) (95% CI)-single PEPSE course: 2.54 (2.19 to 2.96); two or more PEPSE courses: aHR (95% CI) 4.80 (3.69 to 6.25)). The probability of HIV diagnosis was highest in MSM prescribed PEPSE who had also been diagnosed with a bacterial STI in the previous 12â months (aHR (95% CI): 6.61 (5.19 to 8.42)). CONCLUSIONS: MSM prescribed PEPSE are at high risk of subsequent HIV acquisition and our data show further risk stratification by clinical and PEPSE prescribing history is possible, which might inform clinical practice and HIV prevention initiatives in MSM.

OBJECTIVES: Black Africans are one of the key risk groups for HIV in the UK and, among those living with HIV, an estimated 16% and 12% of black African heterosexual men and women, respectively, are undiagnosed and at risk of unknowingly transmitting HIV to their sex partners. Increased HIV test uptake is needed to address this, but there is limited information on how frequently HIV test refusal occurs among those attending sexual health clinics (SHCs). We identified factors associated with HIV test refusal among black African SHC attendees. METHODS: Data on all SHC attendances in England in 2014 were obtained from the genitourinary medicine clinic activity dataset, the mandatory surveillance system for STIs. Analyses were restricted to attendances by HIV-negative black Africans, and bivariate and multivariable associations between demographic and clinical characteristics and HIV test refusal were assessed. All associations were determined using generalised estimating equations logistic regression, and adjusted ORs (aORs) with 95% CIs are reported. RESULTS: Black Africans made 80â 743 attendances at SHCs in 2014 and refused an HIV test on 9021 (11.2%) occasions. HIV test refusal was significantly more likely in women (aOR (95% CI) 1.54 (1.46 to 1.62) vs heterosexual men), and those living in the most deprived areas (1.44 (1.24 to 1.67)), diagnosed with a new STI (1.26 (1.18 to 1.34)) or living in London (1.06 (1.01 to 1.12)). Test refusal was significantly less likely with increasing age (0.99 (0.99 to 0.99)) and men who have sex with men (0.52 (0.43 to 0.63) vs heterosexual men), and in those tested for HIV in the past year (0.85 (0.81 to 0.89)), born outside the UK (0.73 (0.69 to 0.77)) or those attending following partner notification (0.11 (0.03 to 0.38)). CONCLUSIONS: Targeted interventions are needed to improve HIV testing uptake and reduce undiagnosed HIV infection among black Africans attending SHCs, especially heterosexuals residing in deprived areas.

STUDY DESIGN: This study investigated whether access to genitourinary medicine (GUM) clinics meets UK-recommended standards. METHODS: In January 2014 and 2015, postal questionnaires about appointment and service characteristics were sent to lead clinicians of UK GUM clinics. In February 2014 and 2015, researchers posing as symptomatic and asymptomatic 'patients' contacted clinics by telephone, requesting to be seen. Clinic and patient characteristics associated with the offer of an appointment within 48â hours were examined using unadjusted and UK country and patient gender adjusted multivariable logistic regression analyses. In March 2015, a convenience sample (one in four) of clinics was visited by researchers with the same clinical symptoms. Ability to achieve a same-day consultation and waiting time were assessed. RESULTS: In 2015, 90.8% of clinics offered symptomatic 'patients' an appointment within 48â hours when contacted by telephone, compared with 95.5% in 2014 (aOR=0.46 (0.26 to 0.83); p<0.01). The decline was greatest in women (96.0% to 90.1%; p<0.05), and clinics in England (96.2% to 90.7%; p<0.01). For asymptomatic patients, the proportion offered an appointment within 48â hours increased from 50.7% in 2014 to 74.5% in 2015 (aOR=3.06 (2.23 to 4.22); p<0.001), and in both men (58.2% to 90.8%; p<0.001) and women (49.0% to 59.6%; p<0.01). In adjusted analysis, asymptomatic women were significantly less likely to be offered an appointment than asymptomatic men (aOR=0.33 (0.23 to 0.45); p value<0.001). 95% of clinics were able to see symptomatic patients attending in person. CONCLUSIONS: Access to GUM services has worsened for those with symptoms suggestive of an acute STI and is significantly poorer for asymptomatic women. This evidence may support the reintroduction of process targets.

Background: HIV testing is generally accepted as being the lynchpin of a prevention strategy to tackle the HIV epidemic among MSM. However, few studies have analysed in detail the factors that influence HIV test seeking behaviour. Methods: The objective of this article is to analyse the relationship between HIV test seeking behaviour and individual, social and demographic factors in a sample of MSM recruited though a multi-centre bio-behavioural cross-sectional study. A multi-level analysis was conducted to identify factors associated with HIV test seeking behaviour. Results: A total of 2400 men were included in the sample. Age, self-reported sexual orientation, residence, household composition, educational status and perceived homonegativity all seem to impact on test seeking behaviour. Conclusions: The results suggest the need for more targeted testing promotion strategies among MSM that take structural and environmental factors into consideration, as part of a comprehensive public health strategy to address the HIV epidemic.

Since October 2015 up to September 2016, HIV diagnoses fell by 32% compared with October 2014-September 2015 among men who have sex with men (MSM) attending selected London sexual health clinics. This coincided with high HIV testing volumes and rapid initiation of treatment on diagnosis. The fall was most apparent in new HIV testers. Intensified testing of high-risk populations, combined with immediately received anti-retroviral therapy and a pre-exposure prophylaxis (PrEP) programme, may make elimination of HIV achievable.

Four isolated cases of congenital syphilis born to mothers who screened syphilis negative in the first trimester were identified between March 2016 and January 2017 compared with three cases between 2010 and 2015. The mothers were United Kingdom-born and had no syphilis risk factors. Cases occurred in areas with recent increases in sexually-transmitted syphilis among women and men who have sex with men, some behaviourally bisexual, which may have facilitated bridging between sexual networks.

BACKGROUND: Practising unprotected anal intercourse (UAI) with high numbers of partners is associated with increased risk for acquiring and transmitting HIV and other sexually transmitted infections. Our aim was to describe factors associated with UAI with multiple partners in a large sample of MSM from 38 European countries recruited for an online survey in 2010. METHODS: Data are from the European Men-Who-Have-Sex-With-Men Internet Survey (EMIS). The analysis was restricted to men who reported any anal sex with a non-steady partner in the past 12 months, and who were either never diagnosed with HIV, or who had been diagnosed with HIV more than 12 months ago, reported a detectable viral load and did not exclusively serosort (n = 91,477). Multivariable logistic regression was used to compare men reporting UAI with four or more (4+) non-steady partners to two comparison groups: a) no UAI with non-steady partners, and b) UAI with 1-3 non-steady partners. RESULTS: Overall, 9.6% of the study population reported UAI with 4+ partners in the past 12 months. In both models, factors consistently associated with this behaviour were: having been diagnosed with HIV, lower educational levels, use of nitrite inhalants, drugs associated with sex and parties, or erectile dysfunction drugs in the past 4 weeks, using sex-on-site venues in the past 4 weeks, buying or selling sex in the past 12 months, having experienced physical violence due to sexual attraction to men in the past 12 months, reporting sexual happiness, being out to all or almost all of one's acquaintances, and knowing that ART reduces HIV transmissibility. CONCLUSIONS: Effective antiretroviral treatment drastically reduces HIV transmission for men diagnosed with HIV, irrespective of partner numbers. Apart from reducing partner numbers or increasing condom use no other recommendations are currently in place to reduce the risk of HIV acquisition and onward transmission for HIV-negative men practicing UAI with multiple partners. A range of factors were identified as associated with UAI with four or more partners which allow the strengthening and targeting of prevention strategies to reduce HIV transmission risks resulting from condomless anal intercourse with multiple partners.

BACKGROUND: Globally, the HIV epidemic continues to represent a pressing public health issue in Europe and elsewhere. There is an emerging and progressively urgent need to harmonise HIV and STI behavioural surveillance among MSM across European countries through the adoption of common indicators, as well as the development of trend analysis in order to monitor the HIV-STI epidemic over time. The Sialon II project protocols have been elaborated for the purpose of implementing a large-scale bio-behavioural survey among MSM in Europe in line with a Second Generation Surveillance System (SGSS) approach. METHODS/DESIGN: Sialon II is a multi-centre biological and behavioural cross-sectional survey carried out across 13 European countries (Belgium, Bulgaria, Germany, Italy, Lithuania, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the UK) in community settings. A total of 4,966 MSM were enrolled in the study (3,661 participants in the TLS survey, 1,305 participants in the RDS survey). Three distinct components are foreseen in the study protocols: first, a preliminary formative research in each participating country. Second, collection of primary data using two sampling methods designed specifically for 'hard-to-reach' populations, namely Time Location Sampling (TLS) and Respondent Driven Sampling (RDS). Third, implementation of a targeted HIV/STI prevention campaign in the broader context of the data collection. DISCUSSION: Through the implementation of combined and targeted prevention complemented by meaningful surveillance among MSM, Sialon II represents a unique opportunity to pilot a bio-behavioural survey in community settings in line with the SGSS approach in a large number of EU countries. Data generated through this survey will not only provide a valuable snapshot of the HIV epidemic in MSM but will also offer an important trend analysis of the epidemiology of HIV and other STIs over time across Europe. Therefore, the Sialon II protocol and findings are likely to contribute significantly to increasing the comparability of data in EU countries through the use of common indicators and in contributing to the development of effective public health strategies and policies in areas of high need.

OBJECTIVES: The purpose of this article is to assess the distribution of undiagnosed HIV infection in men who have sex with men (MSM) in Southern and Eastern European countries, to describe the differences in epidemiology and behaviour between undiagnosed, diagnosed HIV-positive and HIV-negative MSM and to identify factors associated with undiagnosed HIV infection in the study population. METHODS: A multi-centre biological and behavioural cross-sectional study was conducted in 2008. Time-location sampling was used to recruit men attending different venues. A self-administered questionnaire was completed and oral fluid samples were collected to estimate HIV prevalence. RESULTS: HIV prevalence was 17% in Barcelona, 12% in Verona, 6% in Bratislava, 5% in Ljubljana, 5% in Bucharest and 3% in Prague while undiagnosed HIV infection was 47, 62, 67, 83, 85 and 57%, respectively. Diagnosed HIV-positive men reported more casual partners than HIV-negative MSM (mean: 19 and 9, respectively) (P < 0.001), and they were more likely to self-reported condyloma in the last year than undiagnosed HIV-positive and HIV-negative men (15, 1 and 3%, respectively) (P < 0.001). Factors associated with undiagnosed HIV infection included attending sex-focused venues (OR = 2.49), reporting syphilis in the previous 12 months (OR = 2.56), using poppers at last sexual intercourse (OR = 3.36) and having had an HIV test in the previous year (OR = 2.00). CONCLUSIONS: Many HIV infections remain undiagnosed, and there is evidence of the persistence of frequent risk behaviours and sexually transmitted infections (STI) despite knowledge of HIV-positive status, emphasising the need for a multidimensional approach to HIV/STI prevention. Access to HIV testing should be considered a priority in prevention programs targeted at MSM, especially in Eastern Europe.
