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.

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.

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.

Cuts to sexual health services are putting patients at risk

Cuts to sexual health services in parts of England are placing the care of patients at risk, a new report has warned according to a report published in the BMJ.

The research by the healthcare think tank the King’s Fund concluded that budget cuts of more than 20% to genitourinary medicine (GUM) services in some parts of the country had led to service closures and staffing cuts that have harmed patient care. Experts said that the findings were particularly worrying given that numbers of diagnoses of sexually transmitted infections such as syphilis and gonorrhoea were rising.

Current pressures on services were also having a negative effect on staff morale and leading some staff to consider alternative careers, the report warned.

The researchers analysed data and interviewed frontline staff to examine the effect of funding pressure on patient care across four service areas: GUM, district nursing, elective hip replacements, and neonatal care.

Their findings indicated that sexual health and district nursing had been hardest hit which undermined the vision set out in NHS England’s Five Year Forward View to strengthen prevention and community based services.

The authors said that sexual health services such as GUM had become more prone to budgetary cuts since moving from the NHS to local government, because of local authorities’ legal obligation to balance their books.

Centenary of nationwide free access to sexual health clinics in England and Wales

STI began in 1925 as the British Journal of Venereal Disease, and you can read early editions on the sti.bmj.com website. The very first issue covers skin complaints often mistaken for syphilis, the use of bismuth and malaria inoculation to treat syphilis, and the establishment of a network of clinics following a Royal Commission.1 It also discusses diathermy in the treatment of gonorrhoea!

A hundred years ago, we had no effective treatment for gonorrhoea, and it is sobering to realise we may soon be in the same position. The GRASP surveillance system which tracks antimicrobial resistance in England and Wales shows indications that we are not far from ceftriaxone treatment failures in a report by Town et al.2 In an age of nucleic acid based diagnostics, we need alternatives to culture for detecting resistance. A fascinating report by Graham et al reports that whole genome sequencing can be achieved with urine specimens, including the detection of markers associated with resistance.3 On a related note, this month’s editorial by Nigel Garrett reflects on the perhaps brief life of syndromic management.4

PrEP introduction for adolescent girls and young women

Pre-exposure prophylaxis PrEP use in the sexually active females prevents HIV acquisition.

The International AIDS Conference in Durban, South Africa, in July 2016, has renewed interest and momentum around HIV prevention. High and sustained HIV incidence rates—about 2 million people acquiring HIV every year for the past 5 years—highlight the need for new prevention technologies for populations at substantial risk of HIV.1 As many as 7000 new infections a week are occurring in the most vulnerable adolescent girls and young women in eastern and southern Africa.1 75% of young people in sub-Saharan Africa living with HIV are adolescent girls and young women age 15–24 years; AIDS is the leading cause of death for girls age 10–19 years in Africa.1 To date, prevention efforts have not had sufficient effect on risk of HIV in adolescent girls and young women.

Oral pre-exposure prophylaxis (PrEP)—the use of antiretroviral medications by HIV-negative people to avoid getting HIV—is a new biomedical intervention that has the potential to substantially reduce HIV acquisition in the people at greatest risk. Recent evidence suggests that PrEP was effective among several populations in reducing the risk of HIV infection by 70%.2 Less is known about the effectiveness of PrEP for young women,2 but the intervention could greatly increase the ability of adolescent girls and young women to protect themselves from HIV if they are able to access and use it effectively.

Access to Sexual Health Services for the Somali Community in Birmingham UK

The UK, hosts a large number of refugees from Somalia.

Somalis are absent from much of the official statistics largely because ‘Somali’ is rarely recognised as a distinct ethnic category. Therefore, when decisions are being made in relation to addressing the needs of recently arrived refugees the needs of those who originate from Somalia may be neglected.

Somalis are known to have a high level of need but low uptake of health care services. This included sexual health.

Earlier STIRF funded a project which looked at issues and problems relating to access for sexual health services. The project is now completed and is presented in a meeting held on:

Date: April 27
Venue: Birmingham City University
Time: 16.00 – 18.00

Risks for pelvic inflammatory disease in students

In the latest issue of the Sexually Transmitted Infections, Phillip Hay and colleagues in the UK report on a prospective study of female students attending 11 universities and 9 further education colleges in London.

At the start, the students were asked to fill a questionnaire and provide a self taken vaginal sample for infection screening. After 12 months, they were assessed for pelvic inflammatory disease (PID), a condition that can lead to infertility and other complications.

PID was found in 1.6% of the particpants. Unsurprisingly the strongest predictor of PID was the presence of Chlamydia trachomatis at the first visit (relative risk (RR) 5.7).

However, adjusting for this, the authors reported that significant predictors of PID were ≥2 sexual partners (RR 4.0) or a new sexual partner during follow-up (RR 2.8), and age <20 years (RR 3.3). Somewhat surprisingly recruitment from a further education college rather than a university also increased the relative risk of PID 2.6 fold, perhaps reflecting different health protection behaviors (eg condom use) between the two groups.

The study concluded that in addition to known risk factors such as multiple or new partners in the last 12 months and younger age, attending a further education college rather than a university were risk factors for PID.

They recommended that sexual health education and screening programs could be targeted at these high-risk groups.
