British guidelines advise treatment of This retrospective analysis reviewed laboratory and clinical data pertaining to all positive 340 samples were included from mostly male (74.4%) patients with a mean age of 30 years. The majority of tests were sent for urethritis (63.8%), and most infections were present without concurrent STIs (83.5%). 183 (53.8%) samples were MRAM positive; 157 (46.1%) were wild type. 152/183 (83.1%) received MRAM-guided treatment. 49/152 (32.2%) cases of MRAM-guided treatment failure were identified. 32/49 (65.3%) achieved either microbiological or clinical cure through a variety of treatment regimens. 66.6% of nine patients who received pristinamycin achieved microbiological cure; two patients were cured by minocycline. Many patients received multiple courses of moxifloxacin despite previous failures. Whilst high compliance with recommended MRAM-guided therapy was identified, there were also high rates of quinolone therapy failure (32.2%). Barriers to appropriate treatment include a lack of quinolone resistance assays and the non-availability of sitafloxacin in Europe, along with the limited availability of pristinamycin and minocycline in the UK during the study dates. We recommend developing a standardised management pathway for treatment resistant cases.
