Abstract

IntroductionNucleic acid amplification testing (NAAT) is used in GUM clinics to diagnose GC infection; however its in-built sensitivity potentially detects DNA from non-viable organisms following successful treatment. BASHH guidelines stipulate that test of cure with NAAT (TOC) should take place 2 weeks post-treatment.This study aims to determine whether this is an adequate time interval to perform TOC. We also analysed the changing pattern of antibiotic sensitivity between 2007 – 2016.MethodsAll GC cases at our clinic between 01/01 and 30/06 in 2007–2016 were identified, assessed for antibiotic sensitivity and analysed for TOC data from 2013–2016.ResultsOf 131 cases in 2016, culture and sensitivities were available for 80, with TOC in 63.TOC was performed between 6 and 77 days post-treatment with mean, median and mode of 18, 14 and 14 days respectively.DiscussionNo cultures were resistant to ceftriaxone. This is the first year a case has shown reduced susceptibility to 4 antibiotic groups. From 2015-2016 there has been an increase in GC fully sensitive to the antibiotic testing panel.Our data supports BASSH guidelines for TOC 2 weeks post-treatment.
