Infection by Chlamydia trachomatis the commonest bacterial sexually transmitted infection in the UK and can result in long term complications such as pelvic inflammatory disease and infertility in women.
Once treatment is given to the patient and their partner(s) a test of cure is recommended. However when this should be done is unclear. A similar question hangs over another common sexually transmitted bacterial infection, gonorrhoea.
Dr Gabriel Schembri and his colleagues in Manchester in collaboration with researchers in London have completed a study, part co-funded by STIRF (in conjunction with BASHH) in an effort to answer these questions:
The investigators showed that the site of infection may have an effect on time to clearance of infection, with pharyngeal gonorrhoea infections and vaginal chlamydia infections taking longer to clear than other sites.
The results of this study will help guide clinicians to the timing for tests of cure.
