研究目的:

1.通过前瞻性队列研究,采用分子生物学PCR基因检测技术,对使用替加环素的患者同时筛选出肺炎克雷伯杆菌的毒力因子,同时依据替加环素的剂量分为高剂量组(100mg q12h)和标准剂量组(50mg q12h)。随访两组患者的使用替加环素后,采用Logistic 回归控制混杂因后,分析两组患者的细菌清除率以及临床效果的差异。 2.通过测定两组患者使用替加环素的血药浓度,通过计算各个个体患者的药代动力学/药效学参数(AUC0-24h/MIC),采用矫正混杂因素的ROC曲线分析,得出使用替加环素后最佳的药代动力学/药效学参数(AUC0-24h/MIC)。从而将肺炎克雷伯菌的监测及时及替加环素血药浓度监测技术作为技术手段,从而为临床提供一种新的治疗指标的参考。  

Objectives of Study:

1. Through a prospective cohort study, molecular biological PCR gene detection technique was used to simultaneously screen the virulence factors of Klebsiella pneumoniae in patients using tigecycline, and they were divided into high-dose group (100 mg q12h) and standard-dose group (50 mg q12h) according to the dose of tigecycline. After follow-up of the use of tigecycline in the two groups, logistic regression was used to control for confounding factors, and the differences in bacterial clearance rate and clinical effects between the two groups were analyzed. 2. By measuring the plasma concentration of tigecycline in in the two groups, calculating the pharmacokinetic/pharmacodynamic parameters (AUC0-24h/MIC) of each individual patient, and using ROC curve analysis to correct confounding factors, the optimal pharmacokinetic/pharmacodynamic parameters (AUC0-24h/MIC) after the use of tigecycline were obtained. Therefore, the timely monitoring of Klebsiella pneumoniae and the monitoring technique of tigecycline plasma concentration are used as technical means, so as to provide a new reference for clinical treatment indicators.
