Oropharyngeal gonorrhoea: rate of co-infection with sexually transmitted infection, antibiotic susceptibility and treatment outcome.

The aim of the present study is to investigate the rate of co-infections with other sexually transmitted infections (STIs), antibiotic susceptibility and management of oropharyngeal gonorrhoea diagnosed in a busy genitourinary medicine clinic. The method involved a retrospective study on consecutive patients diagnosed with oropharyngeal gonorrhoea. A total of 131 patients were diagnosed with oropharyngeal gonorrhoea over the study period. The median age of the infected patients was 28 (interquartile range: 22 to 35) years. Forty-one (31%) of patients were younger than 24 years. High rates of co-infection with urethral gonorrhoea (37%), rectal gonorrhoea (37%) or chlamydial infection (16%) were identified. Thirty patients (23%) had only oropharyngeal infection. Twenty-two (17%) patients' isolates showed resistance to at least one antibiotic. Antibiotic resistance among oropharyngeal gonococcal isolates was above 5% between 2000 and 2009. Test-of-cure (TOC) was carried out for only 63 (48%) of patients; non...
