Little is known about the epidemiology of asymptomatic urogenital gonorrhea and antimicrobial susceptibility of Neisseria gonorrhoeae (NG) strains circulating in Indonesia. We studied these issues in 3 large Indonesian cities.Methods
In 2014, participants were recruited from sexually transmitted infection clinics and through outreach in Jakarta, Yogyakarta, and Denpasar. Neisseria gonorrhoeae detection in genital specimens was performed with NG-qPCR at the Public Health Service in Amsterdam. Antimicrobial susceptibility was investigated using the Etest.Results
Among 992 participants, 781 were asymptomatic and included in the risk factors analysis: 439 (56.2%) men, 258 (33.0%) women, and 84 (10.8%) transwomen. They differed significantly in age and were mostly men who have sex with men (35.2%) and female sex workers (29.3%).Results
Overall, 175 (22.4%) asymptomatic participants had a positive NG-qPCR result. Factors positively associated with asymptomatic urogenital gonorrhea were being recruited through outreach (vs clinic-based), inconsistent condom use, and being divorced/widowed (vs single).Results
Among 79 urogenital cultured isolates derived from 27 symptomatic and 52 asymptomatic participants, all isolates were susceptible to ceftriaxone and cefixime, and 98.7% of isolates were susceptible to azithromycin. In contrast, resistance to doxycycline (98.7%) and ciprofloxacin (97.4%) was common.Conclusions
Prevalence of asymptomatic urogenital gonorrhea among Indonesian key populations is very high. Little to no resistance against extended spectrum cephalosporins and azithromycin was observed. However, almost all isolates were resistant to doxycycline and ciprofloxacin. Strengthening outreach sexually transmitted infections services, composing guidelines to screen asymptomatic individuals, and implementing periodical antimicrobial resistance surveillance are recommended.
