What would be missed if we didnt screen men who have sex with men for oral chlamydia trachomatis? A cross-sectional study

What would be missed if we didnt screen men who have sex with men for oral chlamydia trachomatis?... BackgroundThis study aimed to describe oropharyngeal chlamydia (OCT) in gay and bisexually active men (GBM) attending a large urban sexual health clinic in Sydney and determine what proportion of cases would be missed if screening was not routine. Methods: Retrospective data were extracted for all GBM with a positive OCT result between 1 October 2012 and 31 April 2014. The control group consisted of patients who had a negative OCT result on their first visit during the study period, and each patient was only counted once. Results: A total of 74 of 2920 GBM (0.03, 95% CI: 0.020.03) were diagnosed with OCT. The 2920 GBM had a total of 11226 OCT tests performed, demonstrating OCT test positivity of 0.006 (95% CI: 0.0050.008). A total of 62 sexually transmissible infections (STIs) were diagnosed at other sites: 34 rectal chlamydia (CT), 12 throat gonorrohea (GC), 7 urine CT, 7 rectal GC, 1 infectious syphilis and 1 non-gonoccal urethritis (NGU) case. Of the 74 OCT cases, 56 (0.76, 95% CI: 0.640.85) were treated with Azithromycin 51 (69%) as part of standard treatment for their STI co-infection (34 rectal CT, 12 throat GC, 7 urine CT, 7 rectal GC, 1 NGU case) and a further five (7%) were treated as contacts. The remaining 18 people (0.24, 95% CI: 0.150.36) would not have been treated unless they were tested specifically for OCT. Conclusion: Overall, two-thirds of the OCT cases received appropriate treatment and only a small number of cases would have been missed had routine screening not been performed. With an extremely low overall test positivity of 0.6%, screening for OCT at our service adds little to population level health control. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Sexual Health CSIRO Publishing

Abstract

BackgroundThis study aimed to describe oropharyngeal chlamydia (OCT) in gay and bisexually active men (GBM) attending a large urban sexual health clinic in Sydney and determine what proportion of cases would be missed if screening was not routine. Methods: Retrospective data were extracted for all GBM with a positive OCT result between 1 October 2012 and 31 April 2014. The control group consisted of patients who had a negative OCT result on their first visit during the study period, and each patient was only counted once. Results: A total of 74 of 2920 GBM (0.03, 95% CI: 0.020.03) were diagnosed with OCT. The 2920 GBM had a total of 11226 OCT tests performed, demonstrating OCT test positivity of 0.006 (95% CI: 0.0050.008). A total of 62 sexually transmissible infections (STIs) were diagnosed at other sites: 34 rectal chlamydia (CT), 12 throat gonorrohea (GC), 7 urine CT, 7 rectal GC, 1 infectious syphilis and 1 non-gonoccal urethritis (NGU) case. Of the 74 OCT cases, 56 (0.76, 95% CI: 0.640.85) were treated with Azithromycin 51 (69%) as part of standard treatment for their STI co-infection (34 rectal CT, 12 throat GC, 7 urine CT, 7 rectal GC, 1 NGU case) and a further five (7%) were treated as contacts. The remaining 18 people (0.24, 95% CI: 0.150.36) would not have been treated unless they were tested specifically for OCT.
