Global trends of antimicrobial resistance rates in Neisseria gonorrhoeae: a systematic review and meta-analysis
Abstract
BackgroundAntimicrobial resistance (AMR) of Neisseria gonorrhoeae (NG) is a significant public health concern.ObjectiveThe objective of our study was to assess global AMR rates and test them both temporally and geographically.MethodsWe conducted a systematic search of relevant reports from international databases up to 2021. The R statistical package was used for all statistical analyses.ResultsA total of 225 articles were analyzed, and 432,880 NG isolates were examined. The weighted pooled resistance (WPR) rate of different antibiotics was as follows: ciprofloxacin, 51.6%; tetracycline, 45.4%; trimethoprim/sulfamethoxazole, 42.4%; chloramphenicol, 4.1%; kanamycin, 2.1%; gentamicin, 0.6%; and spectinomycin, 0.3%. The resistance to spectinomycin, gentamicin, and kanamycin decreased over time. Significant differences in antibiotic resistance rates were found between the countries.ConclusionOur findings reveal a continuous increase in resistance to some antibiotics (tetracycline and ciprofloxacin) historically used for gonorrhea, even after discontinuation. However, encouraging trends of decreasing resistance to spectinomycin, gentamicin, and kanamycin were observed. Continued global monitoring of AMR profiles in NG isolates is essential for informing appropriate treatment strategies and mitigating the threat of untreatable gonorrhea.
