ABSTRACT We analyzed 254 Shigella species isolates collected in Québec, Canada, during 2013 and 2014. Overall, 23.6% of isolates showed reduced susceptibility to azithromycin (RSA) encoded by mphA (11.6%), ermB (1.7%), or both genes (86.7%). Shigella strains with RSA were mostly isolated from men who have sex with men (68.8% or higher) from the Montreal region. A complete sequence analysis of six selected plasmids from Shigella sonnei and different serotypes of Shigella flexneri emphasized the role of IS26 in the dissemination of RSA.

Acute bacterial diarrhea due to Shigella spp. infection is a common disease in low-income settings. In developed countries, these are usually cases of patients with recent travel history to tropical countries. In recent years, there has been a noticeable increase of cases of Shigella infection amongst men having sex with men in developed countries with no recent travel history. We present a report of two cases of patients hospitalized due to diarrhea of Shigella flexneri origin. During hospitalization, both of them were diagnosed also with primary HIV infection and one patient also had acute hepatitis A. The course of the disease was complicated in both cases and symptoms were severe. In both cases, Shigella was most likely transmitted through sexual contact. Shigella infection should also be considered as one of the sexually transmitted infections.

ObjectivesIn the 2010s, there has been an increase in sexually transmitted infections (STI) in men who have sex with men (MSM) in Australia, and since 2015 also in urban heterosexuals. Men who have sex with both men and women (MSMW) have characteristics that may differ from both men who have sex with men only (MSMO) and heterosexual men. We aimed to compare the sexual practices and the trends in HIV/STI positivity between MSMO and MSMW.DesignRepeated cross-sectional study.SettingA sexual health centre in Melbourne, Australia.ParticipantsMSM aged 18 years and above who attended the Melbourne Sexual Health Centre for the first time between 2011 and 2018. This includes 12 795 MSMO and 1979 MSMW.Primary outcome measuresDemographic characterics, sexual practices and HIV/STI positivity.ResultsCompared with MSMW, MSMO were more likely to practice anal sex and to have condomless receptive anal sex with casual male partners, and less likely to have a current regular relationship. Over the 8-year period, there was an increase in condomless receptive anal sex with casual male partners for both groups (MSMO: from 46.2% to 63.3%, ptrend <0.001; MSMW: from 41.3% to 57.9%, ptrend=0.011). Syphilis positivity increased in MSMO (from 5.5% to 7.9%, ptrend=0.012) and MSMW (from 0.9% to 6.4%, ptrend=0.004) and HIV remained stable. Gonorrhoea increased among MSMO from 2011 to 2014 (from 6.7% to 9.6%, ptrend=0.002), and remained stable from 2015 to 2018. MSMO had higher odds of testing positive for gonorrhoea (adjusted OR (aOR) 1.36, 95% CI 1.13 to 1.64), chlamydia (aOR 1.39, 95% CI 1.16 to 1.67), syphilis (aOR 1.74, 95% CI 1.37 to 2.22) and HIV (aOR 4.60, 95% CI 2.43 to 8.70) than MSMW.ConclusionsMSMW have overall lower condomless sex and lower HIV/STI positivity. In the last years, changes in sexual practices in MSM have affected both MSMW and MSMO leading to an increased STI risk.

Prescribed antibiotic treatments which do not match the therapeutic requirements of potentially co-existing undetected sexually transmitted infections (STIs) can facilitate the selection of antibiotic-drug-resistant clones. To reduce this risk, this modelling assessed the potential applicability of reliable rapid molecular test assays targeting bacterial STI prior to the prescription of antibiotic drugs. The modelling was based on the prevalence of three bacterial STIs in German heterosexual and men-having-sex-with-men (MSM) populations, as well as on reported test characteristics of respective assays. In the case of the application of rapid molecular STI assays for screening, the numbers needed to test in order to correctly identify any of the included bacterial STIs ranged from 103 to 104 for the heterosexual population and from 5 to 14 for the MSM population. The number needed to harm—defined as getting a false negative result for any of the STIs and a false positive signal for another one, potentially leading to an even more inappropriate adaptation of antibiotic therapy than without any STI screening—was at least 208,995 for the heterosexuals and 16,977 for the MSM. Therefore, the screening approach may indeed be suitable to avoid unnecessary selective pressure on bacterial causes of sexually transmitted infections.

Sex With Men

Sexually transmitted infections (STIs) disproportionately affect men who have sex with men, with marked increases in most STIs in recent years. These are likely underpinned by coterminous increases in behavioural risks which have coincided with the development of Internet and geospatial sociosexual networking. Current guidelines advocate regular, annual sexually transmitted infection testing amongst sexually active men who have sex with men (MSM), as opposed to symptom-driven testing. This paper explores sexually transmitted infection testing regularity amongst MSM who use social and sociosexual media. Data were collected from 2668 men in Scotland, Wales, Northern Ireland and the Republic of Ireland, recruited via social and gay sociosexual media. Only one-third of participants report regular (yearly or more frequent) STI testing, despite relatively high levels of male sex partners, condomless anal intercourse and high-risk unprotected anal intercourse. The following variables were associated with regular STI testing; being more ‘out’ (adjusted odds ratio = 1.79; confidence interval = 1.20–2.68), HIV-positive (adjusted odds ratio = 14.11; confidence interval = 7.03–28.32); reporting ≥10 male sex partners (adjusted odds ratio = 2.15; confidence interval = 1.47–3.14) or regular HIV testing (adjusted odds ratio = 48.44; confidence interval = 28.27–83.01). Men reporting long-term sickness absence from work/carers (adjusted odds ratio = 0.03; confidence interval = 0.00–0.48) and men aged ≤25 years (adjusted odds ratio = 0.36; 95% confidence interval = 0.19–0.69) were less likely to test regularly for STIs. As such, we identify a complex interplay of social, health and behavioural factors that each contribute to men’s STI testing behaviours. In concert, these data suggest that the syndemics placing men at elevated risk may also mitigate against access to testing and prevention services. Moreover, successful reduction of STI transmission amongst MSM will necessitate a comprehensive range of approaches which address these multiple interrelated factors that underpin MSM's STI testing.
