Mycoplasma genitalium: the next sexually transmitted superbug?

Antimicrobial resistance and treatment failures are the biggest challenges

The publication of national treatment guidelines does not usually generate headlines in national newspapers. However, the recent release of draft management guidelines for Mycoplasma genitalium infection was accompanied by high profile media coverage suggesting that it is the next sexually transmitted “superbug.” So what are the facts behind these headlines, and how concerned should we be?

First isolated in 1981, M genitalium is the smallest known self replicating bacterium. Most infections are probably asymptomatic and have no adverse health outcomes. Nonetheless, evidence that M genitalium is associated with serious genitourinary and reproductive health morbidity is accumulating.

In men, there is an unequivocal association with non-gonococcal urethritis, and it is detected in up to 40% of men with persistent and recurrent urethritis. In women, a recent meta-analysis found significant associations with a range of clinical syndromes and adverse reproductive health outcomes, including cervicitis, postcoital bleeding, pelvic inflammatory disease, preterm birth, and spontaneous abortion, and a weak association with infertility.

The population prevalence of M genitalium infection ranged from 1.3% to 3.9% and was higher in countries with a low development index. In Britain, a probability sample survey estimated a prevalence of around 1.3% in the sexually active British population aged 16-44 years.4 In common with many other sexually transmitted infections (STIs), M genitalium infection rates can be considerably higher in men who have sex with men, sex workers, and people attending STI clinics.

Antimicrobial resistance

The main concern is M genitalium’s increasing resistance to azithromycin and moxifloxacin, the recommended first and second line treatments in Europe, North America, and Australia, especially in the Asia-Pacific region. For example, single nucleotide polymorphisms in region V of the 23S rRNA gene, which confer macrolide resistance, were found in over 60% of M genitalium specimens from people attending STI clinics in Australia in 2015. Furthermore, selective pressure can lead to the emergence of macrolide resistance after exposure to suboptimal levels of drug.

Importantly, resistance markers are highly correlated with treatment failure, especially when the organism load is high.

New project approved for 2018: Provision and Accessibility of Pre-exposure Prophylaxis (PrEP) in North England and the West Midlands.

Project title: Exploring perspectives on provision and accessibility of Pre-exposure prophylaxis (PrEP) in North England and the West Midlands.

Principal Investigator Professor Marie Claire Van Hout

Team: Professor Vivian Hope; Mr Jim McVeigh: Mrs Jennifer Germain

Site: Public Health Institute, Liverpool John Moores University, Liverpool

The United Kingdom (UK) has a concentrated HIV epidemic, with an estimated 101,200 people living with HIV in 2015. A decrease in diagnoses among men who have sex with men (MSM), the group most affected by HIV transmission, has recently been observed, and is probably due to increased frequency of testing (3 monthly) among those at greatest risk and rapid treatment for those testing positive.

Pre-exposure prophylaxis (PrEP) is an evidence based biomedical HIV prevention strategy which involves HIV negative individuals taking antiretroviral drugs to reduce probability of infection if exposed. The UK PROUD study found PrEP reduced HIV infection risk by 86% among MSM. PrEP is available on the NHS in Wales and Scotland. In October 2017, the IMPACT trial commenced in England, with PrEP being rolled out to 10,000 eligible people.

The project will explore and describe MSM and health professional perspectives on PrEP using qualitative interviews in three Northern cities (Liverpool, Manchester, Sheffield) and one city in the West Midlands (Birmingham) where PrEP is available through the IMPACT trial. Interviews with a purposive sample of participants (8-12 MSM and 4-8 health professionals per city) will focus on: PrEP awareness and sources of information including eligibility, compliance, drug interaction and online sourcing; impact of PrEP on HIV testing patterns, hepatitis C, sexual risk and other sexually transmitted infections; and on issues related to accessing PrEP and optimal service provision

The project is timely given the current IMPACT trial in England, with results informing policy, practice and professional training.

Is antiretroviral treatment for HIV increasing the susceptibility to syphilis

Recently, the world has experienced a rapidly escalating outbreak of infectious syphilis primarily affecting men who have sex with men (MSM); many are taking highly active antiretroviral therapy (ARV) for HIV-1 infection.

Treatment with ARV reduces risk of infection (because of greatly reduced viral load) and near-normal life expectancy for those on treatment. The currently accepted hypothesis is that these factors result in increased sexual risk-taking, especially unprotected anal intercourse, leading to more non-HIV-1 sexually transmitted infections, including gonorrhoea, chlamydia and syphilis.

However, syphilis incidence has increased more rapidly than other STDs. In a recent open access article in the journal Sexually Transmitted Infections, Reckart and colleagues hypothesise that ART itself  may alter the innate and acquired immune responses to Treponema pallidum, the bacterium causing infectious syphilis, and that this biological explanation plays an important role in the current syphilis epidemic.

In a leading article in the same journal, Susan Tuddenham and colleagues (only available to subscribers), find the hypothesis intriguing despite some flaws. They go on to suggest that further work is necessary to look at the mechanisms underlying the current syphilis epidemic.

In the same issue David Glidden et al point out that in the early double blind trials with pre-exposure prophylaxis (PrEP) no increase in syphilis was found between those taking PrEP and those taking placebo. These findings would suggest that short term exposure to ART has no effect on the acquired immune responses to Treponema pallidum.

Sexually transmitted infections: challenges ahead

A commissioned article in Lancet Infectious Diseases on July 9, 2017 highlights some of the major issues and challenges facing us in the growing global epidemic of sexually transmitted infections (STI). Authors Prof Mabhus Unemo et al summarise the key issues as follows:

WHO estimated that nearly 1 million people become infected every day with any of four curable sexually transmitted infections (STIs): chlamydia, gonorrhoea, syphilis, and trichomoniasis. Despite their high global incidence, STIs remain a neglected area of research.

In this Commission, we have prioritised five areas that represent particular challenges in STI treatment and control.

Chlamydia remains the most commonly diagnosed bacterial STI in high-income countries despite widespread testing recommendations, sensitive and specific non-invasive testing techniques, and cheap effective therapy. We discuss the challenges for chlamydia control and evidence to support a shift from the current focus on infection-based screening to improved management of diagnosed cases and of chlamydial morbidity, such as pelvic inflammatory disease.

The emergence and spread of antimicrobial resistance in Neisseria gonorrhoeae is globally recognised. We review current and potential future control and treatment strategies, with a focus on novel antimicrobials.

Bacterial vaginosis is the most common vaginal disorder in women, but current treatments are associated with frequent recurrence. Recurrence after treatment might relate to evidence that suggests sexual transmission is integral to the pathogenesis of bacterial vaginosis, which has substantial implications for the development of effective management approaches.

STIs disproportionately affect low-income and middle-income countries. We review strategies for case management, focusing on point-of-care tests that hold considerable potential for improving STI control.

Lastly, STIs in men who have sex with men have increased since the late 1990s. We discuss the contribution of new biomedical HIV prevention strategies and risk compensation.

Overall, this Commission aims to enhance the understanding of some of the key challenges facing the field of STIs, and outlines new approaches to improve the clinical management of STIs and public health.
