Brief Summary:
Infections caused by imipenem-resistant Acinetobacter baumannii are associated with high mortality and morbidity. The treatment choices for this resistant pathogen are limited.
The objective of the present proposal is to evaluate the effectiveness of combination therapy of imipenem and sulbactam in patients contracted with A. baumannii, and to correlate the clinical effect with the in vitro synergistic results.

Detailed Description:
Acinetobacter baumannii has been increasingly reported in the outbreak of nosocomial infections in the intensive care units, which not only prolong the length of hospital stay but result in high attributable mortality. With its intrinsic resistance to many antimicrobial agents and rapid acquirement of resistance mechanism, resistance to carbapenems, which is often accompanied with resistance to multiple drugs, has emerged worldwide. The limited treatment choice included tigecycline, colistin, and sulbactam. However, the low serum level and bacteriostatic nature of tigecycline hamper its application in blood stream infection, one of the most common presentations of A. baumannii infections. The nephrotoxicity and neurotoxicity of intravenous colistin have caused great concerns in critically ill patients whereas immediate bronchospasm after inhalation and significant clinical consequences have been reported. Sulbactam has been used for decades in combination of ampicillin and well tolerated. However, the emergence of resistance strains and discourage of monotherapy in severely ill patients make combination an attractive choice. Combination of sulbactam and carbapenems has good synergism against A. baumannii with elevated minimal inhibitory concentration (MIC) of sulbactam and/or carbapenems while in an animal model using A. baumannii with higher MIC of both sulbactam and meropenem, survival rate was higher in combination group than sulbactam or meropenem-treated alone group. The similar in vivo bactericidal effect was also observed in combination of imipenem and sulbactam. Despite plenty of in vivo and in vitro studies mentioned above, the clinical studies were limited. Besides, the information regarding the correlation of in vitro synergistic effect of carbapenem and sulbactam with the clinical effect is rarely mentioned. Therefore, our study is aimed to evaluate the effectiveness of combination therapy of imipenem and sulbactam in patients contracted with A. baumannii, and to correlate the clinical effect with the in vitro synergistic results
