研究目的:

主要研究目的: (1)研究头孢他啶阿维巴坦钠、多黏菌素、美罗培南在耐碳青霉烯类肠杆科细菌所致的中枢神经系统感染成人患者中血和脑脊液中药物浓度及血脑屏障穿透性。 (2)以病原学明确的病例为基础入组,早期临床应答和微生物应答为终点,对比头孢他啶阿维巴坦钠联合多黏菌素鞘注和全身多黏菌素B、美罗培南联合多黏菌素B鞘注两种给药方案治疗CRE所致的中枢神经系统感染成人患者的微生物疗效及临床疗效,为该两种给药方案提供循证依据。 次要研究目的: (1)分析药代动力学/药效学(pharmacokinetic/pharmacodynamic, PK/ PD)与疗效相关性,预测这两种给药方案中头孢他啶、阿维巴坦、多黏菌素B、美罗培南在不同MIC值下对耐碳青霉烯类革兰阴性菌中某一菌种达到PK/PD靶值的达标概率(Probability of target attainment, PTA) 和累积响应百分率(Cumulative response percentage,CFR),为CRE所致中枢神经系统感染且临床治疗方案选择有限的成人患者中给药方案的制定提供参考。 (2)评价两种给药方案的安全性评估,包含基线特征、实验室检查结果、生命体征和体格检查、不良事件等。  

Objectives of Study:

Primary objectives: (1) To study the drug concentration and blood-brain barrier penetration of ceftazidime/avibactam sodium, polymyxin B and meropenem in blood and cerebrospinal fluid (CSF) in adult patients with central nervous system infection caused by carbapenem-resistant Enterobacteriaceae. (2) To compare the microbiological and clinical efficacy of therapeutic regimens in the treatment of adult patients with central nervous system infection caused by CRE:① ceftazidime/avibactam sodium combined with polymyxin B (intrathecal and systematic administration); ②meropenem combined with polymyxin B (intrathecal injection). Only patients with clear etiology could be included. Endpoints are early clinical response and microbiological response. Secondary objectives: (1) To analyze the correlation between pharmacokinetic/pharmacodynamic (PK/PD) and efficacy, predict the probability of target attainment (PTA) and cumulative response percentage (CFR) of ceftazidime, avibactam, polymyxin B and meropenem at different MIC values for a certain species of carbapenem-resistant bacteria. (2) To evaluate the safety of the two therapeutic regimens, including baseline characteristics, laboratory test results, vital signs, physical examinations and adverse events.
