摘要
背景:导管相关性无症状细菌尿(CA-ASB)的抗生素治疗率仍然很高。方法:我们对多药耐药铜绿假单胞菌(MDRP) CA-ASB住院患者进行回顾性研究。Cox比例风险回归模型用于确定MDRP CA-ASB患者后续症状感染的预测因素。用Kaplan-Meier曲线分析无症状感染的概率。结果:研究队列包括139例MDRP CA-ASB患者。37例(26.6%)患者出现后续症状性MDRP感染。多因素分析显示,泌尿系统基础疾病(HR = 2.17, 95% CI = 1.01-4.66, p = 0.047)、MDRP的积极抗生素治疗(HR = 2.34, 95% CI = 1.02-5.38, p = 0.046)和复发性菌尿(HR = 3.57, 95% CI = 1.73-7.38, p = 0.001)是随后症状性感染的独立预测因素。Kaplan-Meier分析显示,在接受MDRP CA-ASB积极抗生素治疗的患者中,无症状感染患者的累积比例显著低于未接受抗生素治疗的患者(41.7% vs. 76.4%, p = 0.006, log-rank检验)。结论:这些发现支持了目前针对MDRP CA-ASB的常规抗生素治疗指南,并强调了对高危人群进行密切监测和及时干预的必要性。
Impact of antibiotic treatment and predictors for subsequent infections in multidrug-resistant Pseudomonas aeruginosa catheter-associated asymptomatic bacteriuria
Background
The rate of antibiotic treatment for catheter-associated asymptomatic bacteriuria (CA-ASB) remains high.
Methods
We conducted a retrospective study involving hospitalized patients with multidrug-resistant Pseudomonas aeruginosa (MDRP) CA-ASB. Cox proportional hazards regression models were used to identify predictors for subsequent symptomatic infections in patients with MDRP CA-ASB. The probability of remaining free from symptomatic infection was analyzed using Kaplan-Meier curves.
Results
The study cohort comprised 139 patients with MDRP CA-ASB. Subsequent symptomatic MDRP infections were observed in 37 (26.6%) patients. Multivariate analysis revealed that underlying urologic diseases (hazard ratio [HR] = 2.17, 95% confidence interval [CI] = 1.01-4.66, P = .047), active antibiotic treatment for MDRP (HR = 2.34, 95% CI = 1.02-5.38, P = .046), and recurrent bacteriuria (HR = 3.57, 95% CI = 1.73-7.38, P = .001) were independent predictors for subsequent symptomatic infections. The Kaplan-Meier analysis demonstrated a significantly lower cumulative proportion of symptomatic infection-free patients among those receiving active antibiotic therapy for MDRP CA-ASB than among those who did not (41.7% vs 76.4%, P = .006, log-rank test).
Conclusions
These findings support the current guidelines against routine antibiotic therapy, even for MDRP CA-ASB, and emphasize the need for close monitoring and timely intervention in high-risk populations.
