Background Data on antibiotic resistance of uropathogens for UTI recurrences are lacking. Methods In a retrospective cohort of adults at Kaiser Permanente Southern California with culture-confirmed index uncomplicated UTI (uUTI) between 01/2016 and 12/2020, we examined the number and characteristics of subsequent culture-confirmed UTIs through 2021. Results We identified 148,994 individuals with a culture-confirmed index uUTI (88% female, 44% Hispanic, mean age 51 years [s.d. 19]), of whom 19% developed a subsequent culture-confirmed UTI after a median 300 days (IQR: 126-627). The proportion of UTI due to E. coli was highest for index uUTI (79%) and decreased to 73% for sixth UTI (UTI 6) (p-for trend <0.001), while the proportion due to Klebsiella spp increased from index UTI (7%) to UTI 6 (11%) (p-for-trend <0.001). Non-susceptibility to ≥1 and ≥3 antibiotic classes was observed in 57% and 13% of index uUTIs, respectively, and was higher for subsequent UTIs (65% and 20%, respectively, for UTI 6). Most commonly observed antibiotic non-susceptibility patterns included penicillins alone (12%), and penicillins, trimethoprim-sulfamethoxazole plus ≥1 additional antibiotic class (9%). Conclusions Antibiotic non-susceptibility is common in UTIs and increases with subsequent UTIs. Continuous monitoring of UTI recurrences and susceptibility patterns are needed to guide treatment decisions.

美国大型综合医疗保健系统中尿路感染复发的抗生素耐药性

背景 缺乏尿路感染复发的尿路病原体抗生素耐药性数据。方法 在南加州 Kaiser Permanente 于 2016 年 1 月至 2020 年 12 月期间患有培养证实的无并发症性尿路感染 (uUTI) 的成人回顾性队列中,我们检查了截至 2021 年后续培养证实的 UTI 的数量和特征。 结果 我们确定了 148,994 例具有文化确认指数 uUTI 的个体(88% 女性,44% 西班牙裔,平均年龄 51 岁 [sd 19]),其中 19% 在中位 300 天后出现文化确认 UTI(IQR:126-627) 。大肠杆菌引起的 UTI 比例在 uUTI 指数中最高 (79%),而第六次 UTI (UTI 6) 中则下降至 73%(趋势 p <0.001),而克雷伯氏菌引起的比例则从指数中增加UTI (7%) 至 UTI 6 (11%)(趋势 p <0.001)。在指数 uUTI 中,分别有 57% 和 13% 的患者对 ≥1 类和 ≥3 类抗生素不敏感,而后续 UTI 的比例更高(UTI 6 分别为 65% 和 20%)。最常见的抗生素不敏感模式包括单独使用青霉素(12%),以及青霉素、甲氧苄啶-磺胺甲恶唑加上≥1种其他抗生素(9%)。结论 抗生素不敏感在尿路感染中很常见,并且随着后续尿路感染的发生而增加。需要持续监测尿路感染复发和易感模式来指导治疗决策。
