Experiences of mpox illness and case management among cis and trans gay, bisexual and other men who have sex with men in England: a qualitative study.

Background: The 2022-2024 global mpox outbreak, occurring primarily in the sexual networks of gay, bisexual and other men who have sex with men (GBMSM), has not been accompanied by a focus on patient perspectives of illness. We explore the experiences of GBMSM diagnosed with mpox in England to understand needs for social and clinical support. Methods: In-depth interviews (March/July 2023) were conducted with 22 GBMSM diagnosed with mpox in 2022, randomly selected from a national mpox surveillance database, and 4 stakeholders from clinical/community-based organisations. Interviews covered experiences of illness, testing, diagnosis, treatment and contact tracing, and were recorded, transcribed and analysed with a thematic framework. Findings: Media coverage drawing on homophobic stereotypes around sex between men contributed to feelings of stigma and shame. GBMSM living with HIV appeared to cope better with mpox stigma, drawing on their experiences of being diagnosed with HIV for resilience. Younger GBMSM with less experience of stigmatising illness found mpox diagnosis more traumatic and sometimes required support beyond what was provided. Accessing testing could be complicated when healthcare professionals did not recognise mpox symptoms. Men felt information on course of illness, isolation and vaccination after recovery was often inconsistent and contradictory. GBMSM described that care from sexual health and infectious disease units usually better met their emotional and medical needs. This was frequently linked by men to these services having skills in working with the GBMSM community and managing infection risk sensitively. General hospital services and centralised contact tracing could increase feelings and experiences of stigma as some staff were perceived to lack skills in supporting GBMSM and, sometimes, clinical knowledge. Long-term impacts described by men included mental health challenges, urethral/rectal symptoms and life-changing disability. Interpretation: In this study stigma was a central feature of mpox illness among GBMSM and could be exacerbated or lessened depending on the clinical and social support provided. Involving communities affected by outbreaks in co-producing, planning and delivering care (including contact-tracing) may help improve support provided.

Use of a meningococcal group B vaccine (4CMenB) in populations at high risk of gonorrhoea in the UK.

The meningococcal group B vaccine, 4CMenB, is a broad-spectrum, recombinant protein vaccine that is licensed for protection against meningococcal group B disease in children and adults. Over the past decade, several observational studies supported by laboratory studies have reported protection by 4CMenB against gonorrhoea, a sexually transmitted infection caused by Neisseria gonorrhoeae. Gonorrhoea is a major global public health problem, with rising numbers of diagnoses and increasing resistance to multiple antibiotics. In England, more than 82 000 cases of gonorrhoea were diagnosed in 2022, with nearly half of the cases diagnosed among gay, bisexual, and other men who have sex with men. There are currently no licensed vaccines against gonorrhoea but 4CMenB is estimated to provide 33-47% protection against gonorrhoea. On Nov 10, 2023, the UK Joint Scientific Committee on Vaccination and Immunisation agreed that a targeted programme should be initiated using 4CMenB to prevent gonorrhoea among individuals at higher risk of infection attending sexual health services in the UK. This decision was made after reviewing evidence from retrospective and prospective observational studies, laboratory and clinical data, national surveillance reports, and health economic analyses. In this Review, we summarise the epidemiology of invasive meningococcal disease and gonorrhoea in England, the evidence supporting the use of 4CMenB for protection against gonorrhoea, and the data needed to inform long-term programme planning and extension to the wider population.

Investigating the cause of increased tetracycline-resistant Neisseria gonorrhoeae in England, 2016-20.

BACKGROUND: Antimicrobial resistance in Neisseria gonorrhoeae is a global public health concern. Tetracycline resistance (TetR) increased from 39.4% to 75.2% between 2016 and 2021 in N. gonorrhoeae isolates collected through national surveillance in England, despite the absence of use of tetracyclines for the treatment of gonorrhoea. OBJECTIVES: We investigated whether there was correlation between bacterial sexually transmitted infection (STI) tests performed and treatment with antimicrobials, with increased TetR in N. gonorrhoeae. METHODS: We examined correlations between bacterial STI tests, antimicrobial treatment and TetR in N. gonorrhoeae, using national surveillance data from three large sexual health services (SHS) in London during 2016-20. Doxycycline prescribing data and antibiograms of a non-STI pathogen from distinct patient groups (sexual health, obstetric and paediatric), at a large London hospital, were analysed to identify if doxycycline use in SHS was associated with resistance in a non-STI organism. RESULTS: A substantial increase in TetR was observed, particularly in isolates from gay, bisexual and other MSM (GBMSM). Strong positive correlations were observed exclusively in GBMSM between N. gonorrhoeae TetR and both bacterial STI tests (r = 0.97, P = 0.01) and antimicrobial treatment (r = 0.87, P = 0.05). Doxycycline prescribing increased dramatically during the study period in SHS. Prevalence of TetR in Staphylococcus aureus was higher in isolates sourced from SHS attendees than those from other settings. CONCLUSIONS: Frequent screening of GBMSM at higher risk of STIs, such as those on pre-exposure prophylaxis (PrEP) leading to/and increased use of doxycycline for the treatment of diagnosed infections, may account for the increase in TetR in N. gonorrhoeae.

Rebound of Gonorrhea after Lifting of COVID-19 Preventive Measures, England.

After lifting of all COVID-19 preventive measures in England in July 2021, marked, widespread increases in gonorrhea diagnoses, but not testing numbers, were observed, particularly in persons 15-24 years of age. Continued close surveillance and public health messaging to young persons are needed to control and prevent gonorrhea transmission.

The global burden of sexually transmitted infections.

Understanding the global burden of sexually transmitted infections (STIs) is fundamental to being able to address and control these infections and the health harms they cause. The World Health Organization has renewed its global health sector strategy for the prevention and control of STIs. Reducing STIs remains an integral part of HIV prevention and of sexual and reproductive health programs. Data to measure and describe the global burden continue to improve, with systematic reviews and modeling providing global and regional data for the major STIs. Although substantial gaps remain, as many countries have limited data, the measures available demonstrate the scale of the problem for the main curable STIs, gonorrhea, chlamydia, syphilis, and trichomoniasis; the most common viral STIs, human papillomavirus and genital herpes; the interrelation between STIs and HIV; and the substantially unequal burden of these infections globally and among key populations. Regional and global trends in these infections are affected by population changes; the impact and availability of interventions, such as vaccination; changing behaviors that alter the dynamics of STI transmission; and the role of international travel in promulgating STIs in an increasingly interconnected world.

Genomic epidemiology of syphilis in England: a population-based study.

BACKGROUND: Syphilis is a sexually transmitted bacterial infection caused by Treponema pallidum subspecies pallidum. Since 2012, syphilis rates have risen dramatically in many high-income countries, including England. Although this increase in syphilis prevalence is known to be associated with high-risk sexual activity in gay, bisexual, and other men who have sex with men (GBMSM), cases are rising in heterosexual men and women. The transmission dynamics within and between sexual networks of GBMSM and heterosexual people are not well understood. We aimed to investigate if whole genome sequencing could be used to supplement or enhance epidemiological insights around syphilis transmission. METHODS: We linked national patient demographic, geospatial, and behavioural metadata to whole T pallidum genome sequences previously generated from patient samples collected from across England between Jan 1, 2012, and Oct 31, 2018, and performed detailed phylogenomic analyses. FINDINGS: Of 497 English samples submitted for sequencing, we recovered 240 genomes (198 from the UK Health Security Agency reference laboratory and 42 from other laboratories). Three duplicate samples (same patient and collection date) were included in the main phylogenies, but removed from further analyses of English populations, leaving 237 genomes. 220 (92·8%) of 237 samples were from men, nine (3·8%) were from women, and eight (3·4%) were of unknown gender. Samples were mostly from London (n=118 [49·8%]), followed by southeast England (n=29 [12·2%]), northeast England (n=24 [10·1%]), and southwest England (n=15 [6·3%]). 180 (76·0%) of 237 genomes came from GBMSM, compared with 25 (10·5%) from those identifying as men who have sex with women, 15 (6·3%) from men with unrecorded sexual orientation, nine (3·8%) from those identifying as women who have sex with men, and eight (3·4%) from people of unknown gender and sexual orientation. Phylogenomic analysis and clustering revealed two dominant T pallidum sublineages in England. Sublineage 1 was found throughout England and across all patient groups, whereas sublineage 14 occurred predominantly in GBMSM older than 34 years and was absent from samples sequenced from the north of England. These different spatiotemporal trends, linked to demography or behaviour in the dominant sublineages, suggest they represent different sexual networks. By focusing on different regions of England we were able to distinguish a local heterosexual transmission cluster from a background of transmission in GBMSM. INTERPRETATION: These findings show that, despite extremely close genetic relationships between T pallidum genomes globally, genomics can still be used to identify putative transmission clusters for epidemiological follow-up. This could be of value for deconvoluting putative outbreaks and for informing public health interventions.

STI testing, diagnoses and online chlamydia self-sampling among young people during the first year of the COVID-19 pandemic in England.

PURPOSE: COVID-19 control measures reduced face-to-face appointments at sexual health services (SHSs). Remote access to SHSs through online self-sampling was increased. This analysis assesses how these changes affected service use and STI testing among 15-24 year olds ('young people') in England. METHODS: Data on all chlamydia, gonorrhoea and syphilis tests from 2019-2020, among English-resident young people were obtained from national STI surveillance datasets. We calculated proportional differences in tests and diagnoses for each STI, by demographic characteristics, including socioeconomic deprivation, between 2019-2020. Binary logistic regression was used to determine crude and adjusted odds ratios (OR) between demographic characteristics and being tested for chlamydia by an online service. RESULTS: Compared to 2019, there were declines in testing (chlamydia-30%; gonorrhoea-26%; syphilis-36%) and diagnoses (chlamydia-31%; gonorrhoea-25%; syphilis-23%) among young people in 2020. Reductions were greater amongst 15-19 year-olds vs. 20-24 year-olds. Amongst people tested for chlamydia, those living in the least deprived areas were more likely to be tested using an online self-sampling kit (males; OR = 1.24 [1.22-1.26], females; OR = 1.28 [1.27-1.30]). CONCLUSION: The first year of the COVID-19 pandemic in England saw declines in STI testing and diagnoses in young people and disparities in the use of online chlamydia self-sampling which risk widening existing health inequalities.

Emergence of extensively drug-resistant and multidrug-resistant Shigella flexneri serotype 2a associated with sexual transmission among gay, bisexual, and other men who have sex with men, in England: a descriptive epidemiological study.

BACKGROUND: Shigellosis, also known as bacillary dysentery, is caused by Shigella spp that spread through fecal-oral contact and was traditionally associated with international travel in England. However, sexual transmission of Shigella flexneri and Shigella sonnei among gay, bisexual, and other men who have sex with men (MSM) is now common. In September, 2021, emergence of extensively drug-resistant (XDR) S sonnei harbouring plasmid-encoded blaCTX-M-27 raised concerns over further spread of this extended-spectrum ß-lactamase-producing gene. Using national surveillance in England, we identified and characterised isolates of S flexneri harbouring blaCTX-M-27. METHODS: In this epidemiological study, we identified and phylogenetically characterised S flexneri isolates harbouring blaCTX-M-27 that were referred to the Gastrointestinal Bacterial Reference Unit (GBRU) at the UK Health Security Agency. All isolates referred to the GBRU undergo whole-genome sequencing, enabling antimicrobial resistance determination using genetic markers. Cases were defined as individuals diagnosed with S flexneri harbouring blaCTX-M-27 in England, with a specimen date between Sept 1, 2015, and June 12, 2022, who were phylogenetically confirmed as part of two t10 (approximately ten single nucleotide polymorphisms) clusters. Long-read sequencing elucidated the genomic location of blaCTX-M-27. Laboratory data, integrated with available demographic and clinical information from patient questionnaires, were summarised using descriptive statistics. FINDINGS: A sustained increase in cases of S flexneri harbouring blaCTX-M-27 (n=26) occurred from September, 2021, having been sporadically reported (n=11) in the preceding 6 years. blaCTX-M-27 acquisition events within S flexneri 2a established an XDR paraphyletic (n=8) cluster and a multidrug-resistant monophyletic (n=18) cluster. Cases were among adult male individuals (median age 37 years [IQR 31-46]) and, of the 13 individuals who completed a patient questionnaire, ten (77%) identified as MSM. Antimicrobial treatment was received by seven (54%) of 13 individuals, and four (31%) individuals were admitted to hospital. The IncFII plasmids harbouring blaCTX-M-27 showed high similarity to the XDR S sonnei outbreak plasmid, with 82% and 99% nucleotide similarity between the cluster plasmids and the XDR S sonnei outbreak plasmid. INTERPRETATION: We report emergence of XDR and multidrug-resistant S flexneri 2a harbouring blaCTX-M-27 among MSM in England. Epidemiological and plasmid similarities with the XDR S sonnei outbreak support horizontal acquisition events, emphasising the importance of mobilisable antimicrobial resistance and the need for genomic-based surveillance.

Is there an association between previous infection with Neisseria gonorrhoeae and gonococcal AMR? A cross-sectional analysis of national and sentinel surveillance data in England, 2015-2019.

OBJECTIVES: Quarterly STI screening is recommended for high-risk gay, bisexual and other men who have sex with men (MSM) in the UK, but frequent antibiotic exposure could potentially increase the risk of antimicrobial resistance (AMR) developing in Neisseria gonorrhoeae. We investigated whether repeat diagnosis of gonorrhoea in those attending sexual health services (SHS) was associated with reduced antimicrobial susceptibility. METHODS: Antimicrobial susceptibility data relating to the most recent gonorrhoea diagnosis for each individual included in the Gonococcal Resistance to Antimicrobials Surveillance Programme (2015-2019) were matched to their historical records in the national GUMCAD STI surveillance data set (2012-2019). The number of gonorrhoea diagnoses in the previous 3 years was calculated for each SHS attendee. Logistic regression was used to examine the associations between the number of diagnoses and reduced susceptibility to ceftriaxone (minimum inhibitory concentration (MIC) >0.03 mg/L), cefixime (MIC >0.06 mg/L) and azithromycin (MIC >0.25 mg/L) at the time of the latest diagnosis. RESULTS: Of 6161 individuals included in the analysis, 3913 (63.5%) were MSM, 1220 (19.8%) were heterosexual men and 814 (13.2%) were women. Among MSM, 2476 (63.3%) had 1 past gonorrhoea diagnosis, 1295 (33.1%) had 2-4, 140 (3.6%) 5-9, and 2 (0.1%) ≥10. Most women and heterosexual men (91.7%) had one past gonorrhoea diagnosis; none had more than four. Reduced ceftriaxone and cefixime susceptibility was more common among MSM with two to four gonorrhoea diagnoses (3.8% and 5.8%, respectively) compared with those with one (2.2% and 3.9%, respectively). After adjusting for potential confounding, this association remained (adjusted OR: 1.59, 95% CI 1.07 to 2.37, p=0.02; adjusted OR: 1.54, 95% CI 1.11 to 2.14, p=0.01). No evidence was found for any other associations. CONCLUSIONS: Among MSM, repeat diagnosis of gonorrhoea may be associated with reduced ceftriaxone and cefixime susceptibility. As these are last-line therapies for gonorrhoea, further research is needed to assess the impact of intensive STI screening on AMR.

Detection of 10 cases of ceftriaxone-resistant Neisseria gonorrhoeae in the United Kingdom, December 2021 to June 2022.

Between December 2021 and June 2022, 10 cases of ceftriaxone-resistant Neisseria gonorrhoeae (ST8123; n = 8) were detected in the United Kingdom, compared with nine cases during the previous 6 years. Most of these cases were associated with travel from the Asia-Pacific region; all were heterosexual people, with most in their 20s. Although all cases were successfully treated, not all partners of cases could be traced, and there is a risk of further transmission of ceftriaxone-resistant gonococcal infection within the UK.

Antimicrobial-resistant gonorrhoea: the national public health response, England, 2013 to 2020.

Neisseria gonorrhoeae has developed resistance to all antimicrobials used to treat gonorrhoea, and the emergence of ceftriaxone-resistant strains threatens the last-line option for empirical treatment. The 2013 Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) Action Plan recommended measures to delay the spread of antimicrobial resistance (AMR) in N. gonorrhoeae in England. We reviewed trends in gonococcal AMR since then and the experience of implementing the Action Plan's recommendations to respond to incidents of resistant N. gonorrhoeae. Between 2013 and 2019, diagnoses of gonorrhoea in England rose by 128% to 70,922, the largest annual number ever reported. Over this period, N. gonorrhoeae isolates have become less susceptible to azithromycin (minimum inhibitory concentration > 0.5 mg/L), increasing from 4.7% in 2016 to 8.7% in 2020; this led to a change in first-line treatment for gonorrhoea in the United Kingdom (UK) from dual therapy (ceftriaxone/azithromycin) to ceftriaxone monotherapy in 2019. We also detected the first global treatment failure for pharyngeal gonorrhoea with a dual-therapy regimen (ceftriaxone/azithromycin), followed by an additional six ceftriaxone-resistant strains. Continued engagement of sexual health clinicians and laboratories with the UK Health Security Agency (UKHSA) is essential for the timely detection of N. gonorrhoeae strains with ceftriaxone resistance and to rapidly contain transmission of these strains within England.

Epidemiology of Early Monkeypox Virus Transmission in Sexual Networks of Gay and Bisexual Men, England, 2022.

After community transmission of monkeypox virus was identified in Europe, interviews of 45 case-patients from England indicated transmission in international sexual networks of gay and bisexual men since April 2022. Interventions targeting sex-on-premises venues, geospatial dating applications, and sexual health services are likely to be critical for outbreak control.

Outbreak of sexually transmitted, extensively drug-resistant Shigella sonnei in the UK, 2021-22: a descriptive epidemiological study.

BACKGROUND: Shigellosis, traditionally a foodborne and waterborne infection, causes substantial morbidity globally. It is now a leading cause of sexually transmitted gastroenteritis among gay, bisexual, and other men who have sex with men (MSM). We describe an ongoing outbreak of extensively drug-resistant (XDR) Shigella sonnei in the UK. METHODS: Routine laboratory surveillance (Second Generation Surveillance System, Gastrointestinal Data Warehouse) identified an exceedance of S sonnei clade 5 in England, first detected in September, 2021. Cases within this clade were subsequently reported from Scotland, Wales, and Northern Ireland. Confirmed cases in this outbreak were defined as individuals diagnosed with S sonnei clade 5 in the UK, with a specimen date between Sept 1, 2021, and Feb 9, 2022, who were genomically confirmed as part of a ten-single nucleotide polymorphism (SNP) linkage cluster. We used whole-genome sequencing with SNP typing to identify genomic clusters and antimicrobial-resistance determinants, analysing cases across the UK. We collected demographic, epidemiological, and clinical data from people infected with S sonnei clade 5 in England using questionnaires (standard and bespoke outbreak questionnaires). We used descriptive summary statistics to characterise cases. FINDINGS: 72 cases (70 [97%] male, median age 34 years [IQR 27-39]) belonging to the ten-SNP single linkage cluster of S sonnei clade 5 were identified between Sept 4, 2021, and Feb 9, 2022. Isolates were predominantly XDR, with 66 (92%) of 72 harbouring blaCTX-M-27, a plasmid-mediated gene for production of extended-spectrum ß-lactamases (ESBLs). Of 33 cases with clinical data, 19 (58%) received antibiotics and eight (24%) were hospitalised. 21 (78%) of 27 cases with completed bespoke outbreak questionnaires were HIV-negative MSM taking HIV pre-exposure prophylaxis (PrEP) who reported sexual contacts in the UK and Europe within the incubation period. INTERPRETATION: We highlight the rapid dissemination of XDR ESBL-producing S sonnei in sexual networks of MSM. We recommend strengthening shigella testing where clinically indicated, antimicrobial-resistance surveillance, and integrated health promotion messaging among all MSM, including PrEP users, to reduce the burden of shigellosis.

Effects of COVID-19 Pandemic Response on Service Provision for Sexually Transmitted Infections, HIV, and Viral Hepatitis, England.

Since the coronavirus disease pandemic response began in March 2020, tests, vaccinations, diagnoses, and treatment initiations for sexual health, HIV, and viral hepatitis in England have declined. The shift towards online and outreach services happened rapidly during 2020 and highlights the need to evaluate the effects of these strategies on health inequalities.

Emergence of novel strains of Shigella flexneri associated with sexual transmission in adult men in England, 2019-2020.

National surveillance of shigellosis in England revealed an increase in sexually transmitted Shigella flexneri in adult males in 2019 that persisted throughout 2020. We observed a resurgence of azithromycin-resistant S. flexneri serotype 3a, and the emergence of two novel multidrug-resistant clades of S. flexneri 2a and S. flexneri 1b.

Sexualized drug use and specialist service experience among MSM attending urban and rural sexual health clinics in England and Scotland.

Background: To date, evidence on whether sexualized drug use (SDU) and chemsex occur less frequently in rural compared to urban areas in Britain has been conflicting. This study aimed to better measure and understand whether attending urban versus rural sexual health clinics in the United Kingdom was associated with a difference in men who have sex with men's (MSM) experience of SDU or their access to SDU support. Methods: Men from 29 sexual health services across England and Scotland were recruited by self-completing a waiting room survey. Results: A total of 2655 men (864 MSM) took part. There was no statistically significant difference in recent SDU or chemsex identified in MSM attending rural compared to urban clinics. Gamma-Hydroxybutyrate/Gamma-Butyrolactone (GHB/GBL) was the most commonly reported chemsex drug used in a sexual setting, with equal prevalence of use in urban and rural MSM attendees. Distance travelled for SDU was not significantly different for rural compared to urban MSM. Rural MSM reported a higher rate of unmet need for SDU specific services, although this difference was not statistically significant. Conclusion: Within this sample of MSM, there were no significant differences in sexualized drug use behaviours between those attending rural compared to urban sexual health settings.

Rapid Increase in Lymphogranuloma Venereum among HIV-Negative Men Who Have Sex with Men, England, 2019.

Incidence of lymphogranuloma venereum increased in England during 2018-2019, after a period of decline. Our retrospective analysis of national surveillance data identified a rapid increase in diagnoses among HIV-negative men who have sex with men. These findings indicate a need for sustained surveillance and targeted public health action.
