摘要: 患者,男,45岁,尿道脓性分泌物、排尿痛及尿道疼痛3天就诊。尿液实时荧光核酸恒温扩增检测(simultaneous amplification and testing,SAT)示淋病奈瑟菌RNA阳性;尿道分泌物革兰染色示大量多形核白细胞及细胞内革兰阴性双球菌,培养分离出淋病奈瑟菌,药敏结果提示对头孢曲松及头孢克肟敏感。依据中国指南予头孢曲松1 g肌内注射单次治疗。用药7天后复诊,患者症状明显改善,尿道分泌物镜检及培养均为阴性,尿液SAT亦转阴。

Abstract: We report a case of gonococcal urethritis in a 45-year-old man who presented with a 3-day history of purulent urethral discharge, dysuria, and urethral pain. Urine was tested for N. gonorrhoeae RNA using simultaneous amplification and testing (SAT), with a positive result. Gram staining of the urethral discharge showed numerous polymorphonuclear leukocytes and intracellular Gram-negative diplococci. Culture yielded Neisseria gonorrhoeae, and antimicrobial susceptibility testing demonstrated susceptibility to ceftriaxone and cefixime. The patient was treated with a single 1 g intramuscular dose of ceftriaxone according to the Chinese guideline. At the 7-day follow-up visit after treatment, his symptoms had improved markedly, and urethral microscopy, culture, and repeat urine SAT were all negative.

Key words: gonorrhea, gonococcal urethritis, Neisseria gonorrhoeae, simultaneous amplification and testing, antimicrobial susceptibility
