Cost-effectiveness of antimicrobial resistance point-of-care testing for optimising gonorrhoea treatment

In July, Emma Harding-Esch spoke at the STI and HIV World Congress in Rio on how to best manage the increasing challenge of anti-microbial resistance (AMR). The research she presented was a collaboration between Aquarius Population Health and ADREU St. Georges.  In recent years, there has been an increase in resistance to first-line therapies used to treat STIs such as gonorrhoea. The Aquarius team built a decision tree model to assess the cost-effectiveness of standard care compared to several hypothetical rapid point-of-care tests (POCT) for antibiotic susceptibility. The model simulated a cohort of sexual health clinic attendees. The results showed that while standard care is the cheapest option, AMR POCTs may be cost-effective and maximise the number of effective agents in treatment regimens, providing long-term benefits in some scenarios.

Modelling how point-of-care tests can enable personalised treatment for resistant gonorrhoea infections

We created a mathematical model to investigate the treatment impact and economic implications of introducing an antimicrobial resistance point-of-care test (AMR POCT) for gonorrhoea as a way of extending the life of current last-line treatments. The introduction of AMR POCT could allow clinicians to discern between the majority of gonorrhoea-positive patients with strains that could be treated with older, previously abandoned first-line treatments, and those requiring our current last-line dual therapy. Such tests could extend the useful life of dual ceftriaxone and azithromycin therapy, thus pushing back the time when gonorrhoea may become untreatable.

Managing Mycoplasma genitalium as an STI

Mycoplasma genitalium is a prevalent sexually transmitted infection that causes significant morbidity in men and women and is a co-factor in HIV transmission. However, commercial diagnostic tests are not generally available for M. genitalium and sub-optimal treatment is often given. Diagnostic tests are needed to reduce the risk of the development of antimicrobial resistance and improve patient care.
