RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: CT quantification of aortic valve calcification (CT-AVC) is useful in the assessment of aortic stenosis severity. Our objective was to assess its ability to track aortic stenosis progression compared with echocardiography. METHODS: Subjects were recruited in two cohorts: (1) a reproducibility cohort where patients underwent repeat CT-AVC or echocardiography within 4 weeks and (2) a disease progression cohort where patients underwent annual CT-AVC and/or echocardiography. Cohen's d-statistic (d) was computed from the ratio of annualised progression and measurement repeatability and used to estimate group sizes required to detect annualised changes in CT-AVC and echocardiography. RESULTS: A total of 33 (age 71±8) and 81 participants (age 72±8) were recruited to the reproducibility and progression cohorts, respectively. Ten CT scans (16%) were excluded from the progression cohort due to non-diagnostic image quality. Scan-rescan reproducibility was excellent for CT-AVC (limits of agreement -12% to 10 %, intraclass correlation (ICC) 0.99), peak velocity (-7% to +17%; ICC 0.92) mean gradient (-25% to 27%, ICC 0.96) and dimensionless index (-11% to +15%; ICC 0.98). Repeat measurements of aortic valve area (AVA) were less reliable (-44% to +28%, ICC 0.85).CT-AVC progressed by 152 (65-375) AU/year. For echocardiography, the median annual change in peak velocity was 0.1 (0.0-0.3) m/s/year, mean gradient 2 (0-4) mm Hg/year and AVA -0.1 (-0.2-0.0) cm2/year. Cohen's d-statistic was more than double for CT-AVC (d=3.12) than each echocardiographic measure (peak velocity d=0.71 ; mean gradient d=0.66; AVA d=0.59, dimensionless index d=1.41). CONCLUSION: CT-AVC is reproducible and demonstrates larger increases over time normalised to measurement repeatability compared with echocardiographic measures.
