The characteristics of men who have sex with men (MSM) using post-exposure prophylaxis for sexual exposure (PEPSE) in the pre-exposure prophylaxis (PrEP) era.

OBJECTIVES: HIV pre-exposure prophylaxis (PrEP) is now available in the UK. However, some men who have sex with men (MSM) continue to use HIV post-exposure prophylaxis following sexual exposure (PEPSE) and are not using PrEP. It is important to characterize MSM having condomless anal sex who are not using PrEP. METHODS: In a cross-sectional analysis, we compared the characteristics of MSM who used PEPSE in 2021 with MSM using PEPSE in 2017. RESULTS: Overall, 126 MSM used PEPSE in January to June 2017 and 28 MSM used PEPSE in January to June 2021, a 78% decline in PEPSE use. Those MSM using PEPSE in 2021 were significantly younger (27 vs. 35 years, p < 0.01), more likely to identify as black or from another minority ethnic group [29% (8/28) vs. 8% (10/126); p < 0.01], more likely to attend as a result of a group sex encounter [35% (10/28) vs. 16% (10/126); p = 0.03], more likely to attend following sex involving recreational drug use [32% (9/28) vs. 13% (16/126); p = 0.02], and more likely to initiate PEPSE in the emergency department [35% (10/28) vs. 19% (24/126); p = 0.04] compared with MSM attending in 2017. Those MSM using PEPSE in 2021 were significantly less likely to attend follow-up appointments compared with the 2017 cohort [71% (20/28) vs. 87% (110/126); p < 0.05]. Ninety-five per cent of MSM using PEPSE in 2021 were initiated on PrEP at follow-up. CONCLUSIONS: Despite PrEP being readily available, some MSM continue using PEPSE and these MSM are significantly more likely to be younger, from black or minority ethnic groups, to engage in group sex involving recreational drugs and to attend the emergency department for PEPSE compared with MSM attending in 2017. Increasing the accessibility of PrEP for this group of MSM is important in order to optimize HIV prevention strategies.

Factors associated with testing positive for syphilis among MSM who present as sexual contacts of syphilis from a clinic-based population.

OBJECTIVES: There has been a significant increase in syphilis in men who have sex with men (MSM) in the UK over the past 20 years. Partner notification strategies have increased the number of MSM attending STI clinics as sexual contacts of syphilis. Current guidelines suggest testing and consideration of presumptive antimicrobial treatment. Syphilis treatment with benzathine penicillin requires clinic resources, is painful and is associated with complications. It is important we consider strategies to rationalise presumptive antimicrobial use and promote antimicrobial stewardship. METHODS: We aimed to determine if there are any factors associated with having syphilis among MSM attending as sexual contacts of syphilis in a cross-sectional study. We examined the clinical records of MSM attending as sexual contacts of syphilis from January to December 2019. RESULTS: Of the 6613 MSM who attended for STI testing, 142 of 6613 (2.1%) presented as sexual contacts of syphilis. The median age was 40 years (IQR=31-51), 43 of 142 (30%) were HIV positive, 38 of 142 (27%) had been diagnosed and treated for syphilis in the past, and 11 of 142 (8%) presented with symptoms (possible lesions of primary or secondary syphilis). Thirteen (9%, 95% CI=4.4 to 13.9) tested positive for syphilis on the day of presentation. MSM who were symptomatic (genital ulcer or body rash), HIV positive or had a history of syphilis were significantly more likely to test positive for syphilis (OR=51.88, 95% CI: 3.01 to 893.14, p=0.007). CONCLUSIONS: We have shown that in our clinic-based population of MSM who presented as sexual contacts of syphilis, the factors associated with testing positive for syphilis were: having HIV, having a history of syphilis or presenting with symptoms (possible lesions of primary or secondary syphilis). These factors could be used to rationalise antibiotic treatment among MSM presenting as sexual contacts of syphilis. Further research is needed to validate this finding in other populations of MSM and people affected by syphilis.

Contribution of men who have sex with men (MSM) attending due to contact tracing to the diagnoses of HIV, syphilis and gonorrhoea in MSM from a clinic-based population.

OBJECTIVES: Rates of HIV, syphilis and gonorrhoea have increased over the past 20 years in men who have sex with men (MSM). Contact tracing strategies have increased the number of MSM attending clinics as sexual contacts. Understanding the outcomes of contact tracing could inform future public health policies to reduce the burden of STIs in MSM. METHOD: We aimed to describe the contribution of MSM attending as notified sexual contacts of patients with HIV, syphilis and gonorrhoea to the overall diagnoses of HIV, syphilis and gonorrhoea in MSM in a cross-sectional study. We collected data on all MSM diagnosed with HIV, syphilis and gonorrhoea in 2019 and evaluated which of these MSM were tested due to attending as a sexual contact. RESULTS: Sexual contacts of HIV, syphilis and gonorrhoea contributed to 20% (95% CI=17.3% to 23.7%) of all diagnoses of HIV (3 of 30, 10%), syphilis (28 of 183, 15%) or gonorrhoea (98 of 420, 23%) in the study period. Asymptomatic sexual contacts contributed to 12% (95% CI=9.6% to 14.9%) of all diagnoses of HIV (3 of 30, 10%), syphilis (16 of 183, 9%) and gonorrhoea (57 of 420, 14%). The proportion of MSM diagnosed with gonorrhoea attending as sexual contacts of gonorrhoea (21%) was significantly greater than MSM diagnosed with HIV, attending as sexual contacts of HIV (3%) or MSM diagnosed with syphilis, attending as a sexual contact of syphilis (4%) (p<0.001). Furthermore, the proportion of MSM diagnosed with syphilis, attending as a sexual contact of another STI (11%) was significantly greater than MSM diagnosed with HIV, attending as a contact of another STI (7%) or MSM diagnosed with gonorrhoea, attending as a sexual contact of another STI (2%) (p<0.001). CONCLUSION: Contact tracing contributes significantly to the overall diagnoses of HIV, syphilis and gonorrhoea including asymptomatic sexual contacts in our population. Further efforts to increase the yield from contact tracing may continue to reduce the burden of HIV, syphilis and gonorrhoea within sexual networks of MSM.

A pilot study exploring sexual health clinician confidence and barriers to anal examination and proctoscopy in men who have sex with men.

Anal examination and proctoscopy are important skills needed to facilitate the diagnoses of STIs and cancer. Clinician (25 doctors/15 nurses) confidence was higher for anal examination versus proctoscopy (median Likert scores 4/5 vs 5/5, P≤0.05) and higher in doctors compared with nurses (median Likert scores 5/5 vs 4/5, P<0.008, 4/5 vs 2/5, P<0.005), and related to years of experience (5/5 vs 4/5, P<0.001, 3/5 vs 5/5, P=0.007). Barriers included lack of opportunities for training, concerns about patient reluctance, and lack of available equipment. We need to be innovative when up-skilling the specialist sexual health workforce using online training and optimising opportunities for clinical assessment of MSM.

British Association of Sexual Health and HIV (BASHH) United Kingdom national guideline for the management of sexually transmitted enteric infections 2023.

This is the first British Association of Sexual Health and HIV (BASHH) national guideline for the management of sexually transmitted enteric infections (STEI). This guideline is primarily aimed for level 3 sexual health clinics; however, it may also be applicable to other settings such as primary care or other hospital departments where individuals with STEI may present. This guideline makes recommendations on testing, management, partner notification and public health control of STEI.

Pharyngeal gonorrhoea in men who have sex with men.

Pharyngeal gonorrhoea is important in the transmission dynamics of gonorrhoea, and generation of antimicrobial resistance and the performing of culture remains vital. We reviewed the notes of men who have sex with men (MSM) presenting to our clinic with a positive pharyngeal NAAT for gonorrhoea between January and December 2019. There were 383 cases of NAAT-positive pharyngeal gonorrhoea, and 28 (7%, 95% CI = 5.11-10.36) reported sore throat at presentation. Pharyngeal cultures were taken from 270/383 (70%), and 73/270 (27%) were culture positive with available antimicrobial sensitivities. Overall, the presence of pharyngeal symptoms was not associated with pharyngeal chlamydia (OR = 1.6, CI = 0.19-13.32, p = 0.7), HIV status (OR = 1.1, CI = 0.47-2.57, p = 0.8), positive cultures (OR = 1.9, CI = 0.78-4.62, p = 0.2) or age (p = 0.3). Routine screening of MSM for pharyngeal gonorrhoea is important to maintain surveillance and measures need to be taken to improve pharyngeal culture sampling from MSM.
