Objective

To explore the efficacy of ceftazidime/avibactam (CAZ/AVI) combined with polymyxin in the treatment of carbapenem-resistant Gram-negative bacteria (CRO) pulmonary infections.

Methods

A total of 80 patients with CRO pulmonary infections admitted to our hospital from December 2019 to December 2024 were selected and divided into a control group (n=37) and a CAZ/AVI group (n=43) based on treatment methods. The control group received colistimethate sodium combined with meropenem, while the CAZ/AVI group received CAZ/AVI combined with colistimethate sodium. The clinical efficacy, bacterial clearance rate, and prognosis were compared between the two groups. Based on treatment efficacy, patients were classified into an effective group and an ineffective group, and logistic analysis was performed to identify factors influencing treatment outcomes in CRO pulmonary infections.

Results

The clinical efficacy and bacterial clearance rate in the CAZ/AVI group were higher than those in the control group (P<0.05); there was no statistically significant difference in 28-day mortality between the two groups (P>0.05). The levels of WBC, CRP, PCT, TNF-α, IL-6, and IL-10 in the CAZ/AVI group were lower than those in the control group (P<0.05). In the effective group, age, APACHE Ⅱ score, SOFA score, and the proportion of patients receiving continuous renal replacement therapy (CRRT) were lower than those in the ineffective group, while treatment duration and the proportion receiving CAZ/AVI combined with polymyxin were higher (P<0.05). Logistic analysis indicated that APACHE Ⅱ score, SOFA score, CRRT, treatment duration, and CAZ/AVI combined with polymyxin were influencing factors for treatment outcomes in CRO pulmonary infections (P<0.05).

Conclusion

CAZ/AVI combined with polymyxin shows significant efficacy in the treatment of CRO pulmonary infections.

目的

探究头孢他啶/阿维巴坦(CAZ/AVI)联合多黏菌素对耐碳青霉烯革兰阴性菌(CRO)肺部感染的疗效。

方法

选取2019年12月到2024年12月本院接收的80例CRO肺部感染患者,按治疗方法分为对照组(n=37)和CAZ/AVI组(n=43)。对照组给予多黏菌素E甲磺酸钠联合美罗培南治疗。CAZ/AVI组给予CAZ/AVI联合多黏菌素E甲磺酸钠治疗,比较两组的临床疗效、细菌清除率及预后。根据治疗疗效分为有效组和无效组,并采用Logistic分析CRO肺部感染治疗疗效的影响因素。

结果

CAZ/AVI组的临床疗效、细菌清除率高于对照组(P<0.05);两组的28 d死亡率比较,差异无统计学意义(P>0.05)。CAZ/AVI组的WBC、CRP、PCT、TNF-α、IL -6、IL -10低于对照组(P<0.05)。有效组的年龄、APACHE Ⅱ评分、SOFA评分、接受连续性肾脏替代治疗(CRRT)比例低于无效组,用药疗程、接受CAZ/AVI联合多黏菌素治疗比例高于无效组(P<0.05);Logistic分析表明,APACHE Ⅱ评分、SOFA评分、接受CRRT、用药疗程、CAZ/AVI联合多黏菌素治疗是CRO肺部感染治疗疗效的影响因素(P<0.05)。

结论

CAZ/AVI联合多黏菌素对CRO肺部感染的疗效较为显著。

目的

探究头孢他啶/阿维巴坦(CAZ/AVI)联合多黏菌素对耐碳青霉烯革兰阴性菌(CRO)肺部感染的疗效。

方法

选取2019年12月到2024年12月本院接收的80例CRO肺部感染患者,按治疗方法分为对照组(n=37)和CAZ/AVI组(n=43)。对照组给予多黏菌素E甲磺酸钠联合美罗培南治疗。CAZ/AVI组给予CAZ/AVI联合多黏菌素E甲磺酸钠治疗,比较两组的临床疗效、细菌清除率及预后。根据治疗疗效分为有效组和无效组,并采用Logistic分析CRO肺部感染治疗疗效的影响因素。

结果

CAZ/AVI组的临床疗效、细菌清除率高于对照组(P<0.05);两组的28 d死亡率比较,差异无统计学意义(P>0.05)。CAZ/AVI组的WBC、CRP、PCT、TNF-α、IL -6、IL -10低于对照组(P<0.05)。有效组的年龄、APACHE Ⅱ评分、SOFA评分、接受连续性肾脏替代治疗(CRRT)比例低于无效组,用药疗程、接受CAZ/AVI联合多黏菌素治疗比例高于无效组(P<0.05);Logistic分析表明,APACHE Ⅱ评分、SOFA评分、接受CRRT、用药疗程、CAZ/AVI联合多黏菌素治疗是CRO肺部感染治疗疗效的影响因素(P<0.05)。

结论

CAZ/AVI联合多黏菌素对CRO肺部感染的疗效较为显著。

To explore the efficacy of ceftazidime/avibactam (CAZ/AVI) combined with polymyxin in the treatment of carbapenem-resistant Gram-negative bacteria (CRO) pulmonary infections.

Methods

A total of 80 patients with CRO pulmonary infections admitted to our hospital from December 2019 to December 2024 were selected and divided into a control group (n=37) and a CAZ/AVI group (n=43) based on treatment methods. The control group received colistimethate sodium combined with meropenem, while the CAZ/AVI group received CAZ/AVI combined with colistimethate sodium. The clinical efficacy, bacterial clearance rate, and prognosis were compared between the two groups. Based on treatment efficacy, patients were classified into an effective group and an ineffective group, and logistic analysis was performed to identify factors influencing treatment outcomes in CRO pulmonary infections.

Results

The clinical efficacy and bacterial clearance rate in the CAZ/AVI group were higher than those in the control group (P<0.05); there was no statistically significant difference in 28-day mortality between the two groups (P>0.05). The levels of WBC, CRP, PCT, TNF-α, IL-6, and IL-10 in the CAZ/AVI group were lower than those in the control group (P<0.05). In the effective group, age, APACHE Ⅱ score, SOFA score, and the proportion of patients receiving continuous renal replacement therapy (CRRT) were lower than those in the ineffective group, while treatment duration and the proportion receiving CAZ/AVI combined with polymyxin were higher (P<0.05). Logistic analysis indicated that APACHE Ⅱ score, SOFA score, CRRT, treatment duration, and CAZ/AVI combined with polymyxin were influencing factors for treatment outcomes in CRO pulmonary infections (P<0.05).

Conclusion

CAZ/AVI combined with polymyxin shows significant efficacy in the treatment of CRO pulmonary infections.
