The proportion of Neisseria gonorrhoeae isolates with reduced susceptibility to extended-spectrum cephalosporins (ESCs) has increased rapidly since 2006. Clinicians, researchers, and public health officials need to be prepared for the possibility of an era of untreatable gonorrhea. This review focuses on the evidence for current gonorrhea treatment recommendations, potential future treatment options, and other methods to control gonorrhea.
In addition to an increase in isolates with decreased susceptibility to ESCs, there have been reported treatment failures to both cefixime and ceftriaxone. In response, some countries have increased the recommended cephalosporin dose, and most now recommend dual therapy with an ESC and azithromycin. The pharynx has been implicated as a site for acquiring resistance through transformation with commensal Neisseria species or induced resistance through subtherapeutic antimicrobial levels. Thus, appropriate screening of the pharynx and treatment with a regimen that eradicates gonorrhea from the pharynx is necessary. At present, several studies are evaluating various novel treatment regimens in preparation for an era of untreatable gonorrhea.
Screening for asymptomatic infections, maintaining culture capacity to monitor antimicrobial resistance, treating with ceftriaxone and azithromycin, and ensuring that all sexual partners are treated are among the best strategies to control gonorrhea in the current clime.
自2006年以来,对超广谱头孢菌素(ESC)敏感性降低的淋病奈瑟菌分离株比例迅速增加。临床医生、研究人员和公共卫生官员需要为淋病无法治疗的时代做好准备。本综述重点关注当前淋病治疗建议的证据、未来可能的治疗选择以及控制淋病的其他方法。
除了对ESC敏感性降低的分离株增加外,还报告了头孢克肟和头孢曲松治疗失败的情况。作为应对措施,一些国家提高了推荐的头孢菌素剂量,现在大多数国家推荐使用ESC和阿奇霉素联合治疗。咽部被认为是通过与共生奈瑟菌属转化获得耐药性或通过亚治疗性抗菌药物水平诱导耐药性的部位。因此,有必要对咽部进行适当筛查,并采用能根除咽部淋病的治疗方案。目前,多项研究正在评估各种新型治疗方案,为淋病无法治疗的时代做准备。
筛查无症状感染、保持培养能力以监测抗菌药物耐药性、用头孢曲松和阿奇霉素进行治疗以及确保所有性伴侣都得到治疗,是当前控制淋病的最佳策略。
