摘要:

目的 通过蒙特卡洛模拟(MCS)评价头孢哌酮-舒巴坦分别联合亚胺培南、美罗培南和比阿培南对医院获得多重耐药鲍曼不动杆菌(MRAB)抗感染治疗方案的最佳优化。方法 收集分离自入院48 h后患者临床样本的MRAB 36株,采用美罗培南、亚胺培南、比阿培南和头孢哌酮-舒巴坦单用及联合使用方案,测定其最小抑菌浓度(MIC),确定其联合抑菌(FIC)指数。运用MCS计算不同用药方案的达标概率和累积反应分数(CFR),评价最优化方案。结果 联合用药的MIC90和MIC50均下降明显,3种碳青霉烯类抗菌药物联合头孢哌酮-舒巴坦主要表现为协同作用(所占比例均>50%),其次为相加作用(所占比例≥25%),无关作用和拮抗作用所占比例<12%。结论 MCS对临床抗感染用药方案有指导作用,亚胺培南、美罗培南、比阿培南和头孢哌酮-舒巴坦单独使用的CFR值均小于有效目标值;联合用药时需增加剂量或延长输注时间才能获得满意的有效目标值。

Abstract:

Objective To evaluate the optimal treatment plan of cefoperazone-sulbactam combined with imipenem,meropenem or biapenem by Monte Carlo simulation(MCS) in the treatment of multidrug-resistant Acinetobacter baumannii(MRAB). Methods The minimum inhibitory concentrations(MIC) of imipenem,meropenem,biapenem and cefoperazone-sulbactam alone and in combination against 36 isolates of MRAB were determined,and the fractional inhibitory concentration(FIC) was identified. The probability of achieving target and cumulative response score(CFR) of different anti-infective regimens were calculated by MCS to evaluate the optimal treatment plan. Results MIC90 and MIC50 were both decreased in the evaluation of combined medication. Totally,3 kinds of carbapenems combined with cefoperazone-sulbactam mainly showed that the synergistic effect accounted for >50%,the additive effect accounted for ≥25%,and the irrelevant effect and antagonism accounted for <12%. Conclusions MCS can guide MRAB anti-infective drug treatment. The CFR values of imipenem,meropenem,biapenem and cefoperazone-sulbactam alone are all less than the effective target value,and the effective target value could be obtained by increasing the dose or prolonging the infusion time of combined medication.
