What’s on the rise in Sexually Transmitted Infections?

Lancet Reg Health Eur. 2023. (doi: 10.1016/j.lanepe.2023.100742)

Authors: Axel Jeremias Schmidt, Ulrich Marcus

Invited Commentary.

Several factors related to Sexually Transmitted Infections (STIs) transmission and detection are on the rise. For example, there is increasing evidence that e.g., anal intercourse combined with drug use is becoming common among young heterosexuals, and the diversity of heterosexual practices has been on the rise for many years. Data from the European MSM Internet Survey (2010) illustrate how sexual repertoire diversity impacts STIs in MSM, independent of partner numbers (Fig. 1). Unfortunately, much research neglects these specific factors and persists in employing ambiguous terms like “high-risk behaviour” or “risk compensation”, which are poorly defined and often stigmatizing.

Comparison of the burden of self-reported bacterial sexually transmitted infections among men having sex with men across 68 countries on four continents

BMC Public Health 2023; 23:1008 (doi: 10.1186/s12889-023-15946-8)

Abstract

Background 

Men who have sex with men (MSM) are in general more vulnerable to sexually transmitted infections (STIs) than the heterosexual men population. However, surveillance data on STI diagnoses lack comparability across countries due to differential identification of MSM, diagnostic standards and methods, and screening guidelines for asymptomatic infections.

Methods 

We compared self-reported overall diagnostic rates for syphilis, gonorrhea, and chlamydia infections, and diagnostic rates for infections that were classified to be symptomatic in the previous 12 months from two online surveys. They had a shared methodology, were conducted in 68 countries across four continents between October 2017 and May 2018 and had 202,013 participants.

Results 

Using multivariable multilevel regression analysis, we identified age, settlement size, number of sexual partners, condom use for anal intercourse, testing frequency, sampling rectal mucosa for extragenital testing, HIV diagnosis, and pre-exposure prophylaxis use as individual-level explanatory variables. The national proportions of respondents screened and diagnosed who notified some or all of their sexual partners were used as country-level explanatory variables. Combined, these factors helped to explain differences in self-reported diagnosis rates between countries. The following differences were not explained by the above factors: self-reported syphilis diagnoses were higher in Latin America compared with Europe, Canada, Israel, Lebanon, and the Philippines (aOR 2.30–3.71 for symptomatic syphilis compared to Central-West Europe); self-reported gonorrhea diagnoses were lower in Eastern Europe and in Latin America compared with all other regions (aOR 0.17–0.55 and 0.34–0.62 for symptomatic gonorrhea compared to Central-West Europe); and self-reported chlamydia diagnoses were lower in Central East and Southeast Europe, South and Central America, and the Philippines (aOR 0.25–0.39 for symptomatic chlamydia for Latin American subregions compared to Central West Europe).

Conclusions 

Possible reasons for differences in self-reported STI diagnosis prevalence likely include different background prevalence for syphilis and syndromic management without proper diagnosis, and different diagnostic approaches for gonorrhea and chlamydia.

EMIS-2017 National Reports

Since data collection has closed in February 2018, we have distributed 39 country of residence datasets to our EMIS-2017 partners who are working on a wide range of national reports, in a variety of formats. As these reports are published they will be added here. No datasets were requested from Luxemburg, Bosnia iH, Iceland, or Turkey. As of July 2023, 22 countries have provided at least one national report. Many countries were interrupted in their report writing by the COVID-19 pandemic. We might still receive a report from the Netherlands, Poland, Portugal, and Slovakia. No reports are expected from Bulgaria, Croatia, Finland, Hungary, Lebanon, Lithuania, Latvia, North Macedonia, Romania, Serbia, Slovenia, the Philippines, or the United Kingdom.

Disclaimer: Indicators published on the UNAIDS website for key populations based on data collected by the Latin America MSM Internet Survey (LAMIS) are not official/governmental data of the participating countries.

Available in 33 languages, the European MSM Internet Survey (EMIS-2017) recruited 137,358 qualifying participants from 46 countries across Europe and Lebanon, Israel, Canada and the Philippines. The Latin American MSM Internet Survey (LAMIS) recruited 64,655 participants from 18 countries.

EMIS-2017 was undertaken by researchers from Sigma Research at the London School for Hygiene and Tropical Medicine and the Robert Koch Institute. Data was collected between 18 October 2017 and 31 January 2018.

LAMIS, using the same questionnaire and finishing data collection on 12 May 2018, was the first multi-country survey for gay, bisexual, and other men who have sex with men (MSM) in Latin America. It was implemented by researchers from Right PLUS*, a coalition of researchers from Latin America, Portugal, Spain and the Netherlands, with support from the EMIS team.

EMIS and LAMIS required a great deal of international cooperation and relied on the support of national stakeholders to aid local recruitment. Through this cooperation comparable data are now available for the first time for more than 60 countries across 4 continents.

Changes in the prevalence of self-reported sexually transmitted bacterial infections from 2010 and 2017 in two large European samples of men having sex with men – is it time to re-evaluate STI-screening as a control strategy?

PLoS ONE, 2021; 16(3): e0248582 (doi: 10.1371/journal.pone.0248582).

Abstract

Background/Objectives: Many European countries reported increased numbers of syphilis, gonorrhoea and chlamydia diagnoses among men who have sex with men (MSM) in recent years. Behaviour changes and increased testing are thought to drive these increases.

Methods: In 2010 and 2017, two large online surveys for MSM in Europe (EMIS-2010, EMIS-2017) collected self-reported data on STI diagnoses in the previous 12 months, diagnostic procedures, STI symptoms when testing, number of sexual partners, and sexual behaviours such as condom use during the last intercourse with a non-steady partner in 46 European countries. Multivariate regression models were used to analyse factors associated with diagnoses of syphilis, gonorrhoea/chlamydia, and respective diagnoses classified as symptomatic and asymptomatic. If applicable, they included country-level screening rates.

Results: Questions on STI diagnoses and sexual behaviours were answered by 156,018 (2010) and 125,837 (2017) participants. Between 2010 and 2017, overall diagnoses with gonorrhoea/chlamydia and syphilis increased by 76% and 83% across countries. Increases were more pronounced for asymptomatic compared to symptomatic infections. The proportion of respondents screened and the frequency of screening grew considerably. Condomless anal intercourse with the last non-steady partner rose by 62%; self-reported partner numbers grew. Increased syphilis diagnoses were largely explained by behavioural changes (including more frequent screening). Gonorrhoea/chlamydia increases were mainly explained by more screening and a change in testing performance. A country variable representing the proportion of men screened for asymptomatic infection was positively associated with reporting symptomatic gonorrhoea/chlamydia, but not syphilis.

Discussion/Conclusion: The positive association of country-level screening rates with the proportion of symptomatic infections with gonorrhoea/chlamydia may indicate a paradoxical effect of screening on incidence of symptomatic infections. Treatment of asymptomatic men might render them more susceptible to new infections, while spontaneous clearance may result in reduced susceptibility. Before expanding screening programmes, evidence of the effects of screening and treatment is warranted.
