Study design:

Cohort study 

研究目的:

1、建立准确可靠、简单快速的LC-MS/MS法测定人血浆/血清中头孢他啶阿维巴坦浓度的方法学,并分析头孢他啶阿维巴坦治疗碳青霉烯耐药革兰阴性菌重症感染患者的PK特征,建立其PPK模型,为临床用药提供参考价值。 2、基于PPK模型探讨头孢他啶阿维巴坦治疗重症感染患者PK/PD靶标达成率,以评估头孢他啶阿维巴坦治疗碳青霉烯耐药革兰阴性菌重症感染患者的临床有效性与安全性。 3、通过对碳青霉烯耐药革兰阴性菌重症感染患者进行头孢他啶阿维巴坦TDM干预研究,为临床合理用药提供数据支持。  

Objectives of Study:

1. To establish an accurate, reliable, simple and rapid LC-MS/MS method for the determination of ceftazidime avibactam concentration in human plasma/serum, and to analyse the PK characteristics of ceftazidime avibactam in the treatment of patients with severe infection with carbapenem-resistant gram-negative bacteria, and to establish its PPK model to provide reference value for clinical use. 2. To explore the PK/PD target achievement rate of ceftazidime avibactam in patients with severe infection based on the PPK model, in order to evaluate the clinical efficacy and safety of ceftazidime avibactam in the treatment of patients with severe infection with carbapenem-resistant gram-negative bacteria. 3. To provide data support for the rational use of clinical drugs by conducting a study on ceftazidime avibactam TDM in patients with severe infection with carbapenem-resistant gram-negative bacteria.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

①男性或女性,年龄18~80周岁(含边界值); ②重症感染患者; ③原发感染部位标本经细菌培养确诊为至少一种对头孢他啶阿维巴坦敏感的碳青霉烯耐药革兰阴性病原菌(包括但不限于碳青霉烯耐药肠杆菌目和/或铜绿假单胞菌)所致的感染; ④首次给药前48小时内可获取足够的呼吸道分泌物、血液、腹腔积液等样本用于细菌培养与药敏试验; ⑤静脉注射头孢他啶阿维巴坦 ≥ 72小时; ⑥理解遵守研究程序和方法,自愿参加本研究,并书面签署知情同意书者。

Inclusion criteria

1 Males or females, aged 18 to 80 years (inclusive); 2 Critically ill patients; 3 Primary infection site specimens confirmed by bacterial culture to have at least one strain of Carbapenem-resistant Gram-negative pathogens sensitive to Ceftazidime-Avibactam (including but not limited to Carbapenem-resistant Enterobacteriaceae and/or Pseudomonas aeruginosa); 4 Sufficient respiratory secretions, blood, peritoneal fluid and other samples for bacterial culture and susceptibility testing can be obtained within 48 hours prior to the first dose; 5 Intravenous administration of Ceftazidime-Avibactam for >= 72 hours; 6 Individuals who understand and comply with the research procedures and methods, voluntarily participate in this study, and sign an informed consent form.

排除标准:

①对β-内酰胺类抗菌药物包括头孢菌素类、含β-内酰胺酶抑制剂头孢菌素类复合制剂或注射用头孢他啶阿维巴坦钠及其辅料有过敏史者 ②达到稳态后(首次用药24-48h后)无法采集到血液标本的患者 ③呼吸衰竭或不可逆心肌功能障碍等需要行ECMO治疗的患者 ④若能获得首剂给药前72h内微生物的培养结果,且存在下列任一情形者: a.由革兰氏阳性菌引起的感染,且没有伴随革兰阴性菌感染者(允许革兰氏阳性菌引起的多种微生物混合感染,前提是存在革兰阴性菌需要进行治疗); b.预期对注射用头孢他啶阿维巴坦钠治疗无反应/敏感率较低的革兰阴性菌(例如鲍曼不动杆菌、难治耐药性铜绿假单胞菌等)引起的感染者(若研究者认为菌株为不需特殊治疗的定植菌,且符合其他标准,则患者可参与本研究); c.对注射用头孢他啶阿维巴坦钠耐药的革兰阴性菌引起的感染者(若酶型检测为金属酶,或经药敏等确认,研究者认为头孢他啶阿维巴坦联合氨曲南可以进行治疗,且符合其他标准,则患者可参与本研究); ⑤研究期间计划使用方案规定的禁用药物者 ⑥已知或疑似有艰难梭菌相关性腹泻(CDAD)病史者。 ⑦人类免疫缺陷病毒(HIV)抗体阳性。 ⑧目前正处于妊娠或哺乳期的女性患者 ⑨经研究者判定,任何有可能增加试验风险、影响患者对方案依从性或影响患者完成试验的生理或心理疾病或状况者。 ⑩参与本研究的工作人员或其直系亲属。

Exclusion criteria:

(1) Those who have a history of allergy to β-lactam antibacterial drugs, including cephalosporins, cephalosporins-containing β-lactamase inhibitors, or ceftazidime avibactam sodium for injection and its excipients (2) Patients who are unable to collect blood samples after reaching steady state (24-48 hours after the first dose). (3) Patients with respiratory failure or irreversible myocardial dysfunction who require ECMO therapy (4) If the culture results of microorganisms within 72 hours before the first dose of administration can be obtained, and any of the following conditions exist: a. Infection caused by gram-positive bacteria without concomitant gram-negative bacteria infection (polymicrobial co-infection caused by gram-positive bacteria is allowed, provided that gram-negative bacteria are present and need to be treated); b. Patients with infections caused by gram-negative bacteria (such as Acinetobacter baumannii, refractory drug-resistant Pseudomonas aeruginosa, etc.) that are expected to have no response/low sensitivity rate to treatment with ceftazidime avibactam sodium for injection (if the investigator considers the strain to be a colonizing bacterium that does not require special treatment and meets other criteria, the patient can participate in this study); c. Patients with infections caused by gram-negative bacteria resistant to ceftazidime avibactam sodium for injection (if the enzyme type is detected as metalloenzyme, or confirmed by drug sensitivity, the investigator believes that ceftazidime avibactam combined with aztreonam can be treated, and meets other criteria, the patient can participate in this study); (5) Those who plan to use the prohibited drugs specified in the protocol during the study period (6) Known or suspected history of Clostridium difficile-associated diarrhoea (CDAD). (7) Positive human immunodeficiency virus (HIV) antibody. (8) Female patients who are currently pregnant or lactating (9) Any physical or psychological disease or condition that may increase the risk of the trial, affect the patient's compliance with the protocol, or affect the patient's completion of the trial, as judged by the investigator. (10) Staff members or their immediate family members participating in this study.
