Background Mathematical models have demonstrated that the majority of gonococcal transmission is from oropharynx to oropharynx (i.e. kissing) among men who have sex with men (MSM). The aim of this study is to investigate the association between the number of partners within specific time periods and gonorrhoea and chlamydia positivity. Methods: This was a retrospective data analysis of MSM attending the Melbourne Sexual Health Centre between 2007 and 2016. Univariable and multivariable logistic regression analyses, with generalised estimating equations (GEE), were performed to determine if the number of partners within specified time periods was associated with site-specific gonorrhoea and chlamydia positivity. Results: There were 45933 consultations which included 15197 MSM. Oropharyngeal gonorrhoea positivity was associated with the number of partners in the past 3 months, but not the number of partners 4–12 months ago; men who had ≥6 partners in the past 3 months had significantly higher odds of acquiring oropharyngeal gonorrhoea (aOR 1.93; 95% CI 1.61–2.31), but this was not the case for men who had ≥6 partners 4–12 months ago. Anorectal gonorrhoea and chlamydia and urethral chlamydia were associated with the number of partners in both time periods after adjusting for age and condom use. Conclusions: The association of oropharyngeal gonorrhoea with the number of recent partners, but not partners from an earlier period, unlike anorectal gonorrhoea and anorectal and urethral chlamydia, could be explained by a shorter duration of oropharyngeal gonococcal infection. Annual screening for gonorrhoea may be insufficient to materially reduce oropharyngeal prevalence.

The number of contacts of STIs who are tested and treated is generally low. Patient delivered partner therapy ( PDPT) has been proposed in order to increase the number of sexual partners of the index case that are treated. PDPT does not require the contact to be clinically assessed and tested. We sought to determine whether PDPT for chlamydial infection would result in missed diagnoses of other STIs or of the complications of chlamydial infection. The Sydney Sexual Health Centre database was accessed to identify patients who presented as contacts of chlamydia and chlamydia associated conditions and to determine whether other STIs were diagnosed at the time of presentation. Those who were contacts of more than one bacterial STI or HIV were excluded. In the 3 years from June 2003 to June 2006, 626 individuals presented as contacts of chlamydia, NGU or PID. Of these, 212 (34%) tested positive for Chlamydia trachomatis by PCR. Of the 442 heterosexual patients, 36% had chlamydial infection diagnosed. Of the 184 men who had sex with men (MSM), 29% had chlamydial infection diagnosed. Of the heterosexuals who presented as contacts, 13 were diagnosed with other bacterial STIs or complications of chlamydia. Of these, 2 women and 2 men had gonococcal infection (0.9%), 1 woman had syphilis of unknown duration, 6 women (3%) were diagnosed with PID and 2 men (0.8%) with epididymitis. Of the MSM, 9 (5%), were newly diagnosed with HIV infection, 15 (8%) with gonococcal infection and none with syphilis. PDPT would result in a missed opportunity to diagnose other STIs in MSM. In heterosexuals a small number of cases of PID and epididymitis would be inadequately treated and a small number of gonococcal infections would be missed.

ObjectiveChlamydia and gonorrhoea are common sexually transmitted infections that infect the oropharynx, anorectum and urethra in men who have sex with men (MSM). This study aimed to examine the pattern of infection at more than one site (multisite) for chlamydia and gonorrhoea among MSM.MethodsThis was a retrospective study of MSM attending the Melbourne Sexual Health Centre for the first time between 2018 and 2019. We included MSM aged ≥16 years who had tested for Neisseria gonorrhoeae and Chlamydia trachomatis at all three sites (oropharynx, anorectum and urethra). We compared infections that occurred at a single site (termed single-site infection) and those that occurred at more than one site (termed multisite infections).ResultsOf the 3938 men who were tested for chlamydia and gonorrhoea, 498/3938 men (12.6%, 95% CI 11.5% to 13.6%) had chlamydia at any site, of whom 400/498 (80.3%, 95% CI 78.9% to 81.2%) had single-site chlamydia infection, and 98/498 (19.7%, 95% CI 16.2% to 23.1%) had multisite infections. A similar proportion of men had gonorrhoea at any site (447/3938, 11.4%, 95% CI 10.3% to 12.2%), but among these 447 men, single-site infection was less common (256/447, 57.3%, 95% CI 52.6% to 61.7%, p<0.001) and multisite infection (191/447, 42.7%, 95% CI 38.2% to 47.3%, p<0.001) was more common than chlamydia. There were also marked differences by anatomical site. Urethral infection commonly occurred as single sites (75/122, 61.5%, 95% CI 52.8% to 70.1%) for chlamydia but uncommonly occurred for gonorrhoea (12/100, 12.0%, 95% CI 5.6% to 18.3%, p<0.001). In contrast, anorectal infection uncommonly occurred as multisite infection for chlamydia (98/394, 24.9%, 95% CI 20.6% to 29.1%) but was common (184/309, 59.5%, 95% CI 54.0% to 64.9%, p<0.001) for gonorrhoea.ConclusionsThe markedly different pattern of site-specific infection for chlamydia and gonorrhoea infections among the same MSM suggests significant differences in the transmissibility between anatomical sites and the duration of each infection at each site.

HIV prevalence is increasing rapidly among men who have sex with men (MSM) in China and potentially associated with the number of male sexual partners that each man has on average. This study estimates the distribution of the number of male sexual partners among Chinese MSM through a comprehensive review of English and Chinese published literature. The overall median number of male sexual partners of Chinese MSM in the past 6 months China was estimated to be 1.5 (95% CI, 1.1-1.9) and 3.8 (95% CI 1.5-6.9) sexual partners in the past 6-month and 12-month periods respectively. An estimated 31% of sexual partners of MSM in China are regular partners, 54% are casual partners, and 16% are commercial partners. The reported numbers of sexual partners has not changed over time during the past decade. The numbers of male sexual partners reported by Chinese MSM is consistently lower than other settings and may not be sufficient to explain the recent rapid increase in HIV prevalence.

‘Fuckbuddies’ are a type of regular sexual partner with whom men have ongoing sexual contact, generally in the absence of romantic attachment. We surveyed 989 men who have sex with men (MSM) at the Melbourne Sexual Health Centre, Australia, with the aim of determining the frequency of ‘fuckbuddy’ partnerships among sexual health clinic attendees and assessing their sexual risk. The majority (60%) of 1139 regular partnerships were described as ‘fuckbuddies’. Most MSM (63%) with a ‘fuckbuddy’ had multiple ‘fuckbuddies’. MSM with ‘fuckbuddies’ were more likely to also have casual sexual partners (odds ratio [OR] 5.7; 95% confidence interval 3.6–8.9) and had more casual sexual partners (median of 4 versus 1, p < 0.001) and more rectal chlamydia (12.4% versus 5.7%; adjusted OR 2.3; p < 0.05) than MSM without ‘fuckbuddies’, and this risk persisted after adjusting for total numbers of sexual partners. Our findings suggest that patients with ‘fuckbuddies’ are at particular risk of sexually transmitted infections. We argue that clinicians should specifically ask about ‘fuckbuddy’ partnerships as part of their risk assessment during patient interviews, as these patients may benefit from HIV prevention strategies such as pre-exposure prophylaxis (PrEP).

Spread Of Infection

Gonorrhoea is on the rise in Sweden and in many other European countries. The present report describes and evaluates the gonorrhoea trends in Sweden from 2001 to 2008 when an increase of 32% was reported. Up to 86% of the cases were reported in men, with the highest proportion among heterosexually infected men (41-59% during these years). Heterosexually infected men more often acquired gonorrhoea abroad, especially in Thailand, whereas women and men who have sex with men were more likely to acquire the infection within Sweden. The recent increase in gonorrhoea cases in Sweden is most likely due to adoption of more risky sexual behaviour (e.g. an increase in the number of sexual partners and the number of new/casual sexual partners and/or low use of condoms) in the Swedish population. Further research regarding more effective identification and description of sexual transmission chains and sexual networks is needed in order to follow the spread of infection and to recognise more effective interventions to prevent the spread of gonorrhoea and also other sexually transmitted infections.

Objective Since the recent introduction of preexposure prophylaxis (PrEP), several studies have reported a decrease in the use of condoms and a rise in STIs among users. This rise in risk behavior associated with the advent of PrEP is known as “risk compensation.” The aim of this study is to measure clinical and behavioral changes associated with the introduction of PrEP by analyzing condom use for anal intercourse, number of sexual partners, sexualized drug use and STI incidence. Methods We performed a retrospective descriptive study of PrEP users followed every 3months over a 2-year period spanning 2017–2019 in a referral clinic specializing in STI/HIV in Madrid, Spain. One hundred ten men who have sex with men and transgender women underwent regular screening for STIs and hepatitis C virus (HCV) infection. Sociodemographic, clinical, and behavioral data were gathered for all subjects studied. Results The risk compensation observed in this study consisted primarily of a lower rate of condom use, while the number of sexual partners and recreational drug consumption remained stable. We observed a very high incidence of STIs in this sample, particularly rectal gonorrhea and chlamydia. The factors shown to be independently associated with the presence of an STI on multivariate analysis were age below 30 years and over 10 sexual partners/month. Conclusion The incidence of STI acquisition was higher than expected, indicating a need for strategies to minimize this impact, particularly among younger individuals with a higher number of sexual partners.

Objectives: We examined definitions of “safe sex” among adults in California, and assessed whether definitions varied by sociodemographic characteristics and sexual behavior. Methods: We analyzed crosssectional data from the “AIDS Knowledge, Attitudes, Beliefs, and Behaviors (KABB) Survey,” a statewide telephone survey of California adults conducted in 2000. Results: The four most common definitions of safe sex were condom use (68.0%), abstinence (31.1%), monogamy (28.4%), and safe partner (18.7%). Definitions were associated with sex, age, race/ethnicity, education, and number of sexual partners in the past 12 months. Conclusions: Most adults defined safe sex in terms of condom use either alone or in conjunction with other methods. Individuals’ definitions were complex and varied across sociodemographic groups which suggest the need for policies and programs which reflect this diversity.

Background: Men who have sex with men (MSM) university students were more likely to be infected with HIV than the general population due to various reasons, including having multiple sexual partners, having anal sex without a condom, and using alcohol and drugs. The objective of this study was to investigate the factors associated with multiple sexual partners among MSM university students in northern Thailand. Methods: The participants of this study were 139 MSM university students. The number of sexual partners in the last 12 months was used as the main outcome variable. Information was collected using an online self-administered questionnaire. The number of sexual partners for categories of participants was described as median and interquartile range. Factors that were independently associated with multiple sexual partners were identified using binary logistic regression analysis. Results: Findings showed that seeking sexual partners online (AOR = 1.72; 95% CI 3.10 - 44.29), drinking alcohol within the last 12 months (AOR=9.73; 95% CI 1.38 - 68.47), and having a self-perception of HIV risk (AOR=3.63; 95% CI 1.15 - 11.50) were independently associated with having multiple sexual partners. Conclusion: Health agencies and universities should develop strategies to promote life skills related to sexual responsibility, appropriate use of online media, and reduction of alcohol consumption among MSM university students.

Background Non-occupational post-exposure prophylaxis (NPEP) is available to people with a potential risk for HIV exposure within the preceding 72 h. We sought to determine if men who have sex with men (MSM) and receive NPEP had a significantly different risk profile (before the preceding 72 h) from MSM not receiving NPEP. If this is the case, NPEP consultations may act as a cue for also discussing pre-exposure prophylaxis. Methods: We conducted a retrospective analysis to compare the demographic characteristics, sexual practices and clinical diagnoses of MSM who were NPEP users and those who were non-NPEP users attending Melbourne Sexual Health Centre from January 2008 to December 2014. Univariate and multivariate logistic regression models were used to examine the association between NPEP use and risk practices. Generalised estimating equations were used to adjust for within-individual correlations related to multiple visits of the same individual. Results: Of the 40 395 MSM consultations included in the study, 1776 consultations (4%) were related to NPEP prescription. NPEP prescribing was associated with ever having injected drugs (adjusted odds ratio (AOR) 1.8, 95% confidence interval (CI): 1.4–2.3), sex with males only (AOR 1.9, 95% CI: 1.6–2.3), more than three male partners in the past 3 months (AOR 1.5, 95% CI: 1.4–1.7) and inconsistent condom use with these partners within the past 3 months (AOR 2.1, 95% CI: 1.9–2.4). Sex workers (AOR 0.6, 95% CI: 0.3–0.9), and men reporting sex overseas within the past 12 months (AOR 0.7, 95% CI: 0.6–0.8) were less likely to receive NPEP. MSM who used NPEP were more likely to test positive for any sexually transmissible infection (AOR 1.2, 95% CI: 1.0–1.4). Conclusions: MSM receiving NPEP generally had a higher risk profile than MSM not requesting NPEP, indicating that NPEP was used by MSM at higher risk for HIV. Therefore, consultations for NPEP may be an opportune time for also discussing pre-exposure prophylaxis for HIV.
