Clinical Treatment Options for Carbapenem-Resistant Gram-Negative Infections in China: a Single Center Real-World Experience

Background: Carbapenem-resistant gram-negative bacteria pose a serious threat worldwide, and some patients even have rapidly aggravated life-threatening infection. However, as a result of the complexities of clinical therapy, antibiotic options against carbapenem-resistant pathogens have not yet been fully standardized. It should be individualized to control carbapenem-resistant pathogens in accordance with the different region.Methods: In this study, we conducted a retrospective study in 65,000 inpatients over a 2-year period that involved a total of 86 patients from whom carbapenem-resistant gram-negative bacteria were isolated.Results: Monotherapy using trimethoprim/ sulfamethoxazole, amikacin, meropenem, and/or doxycycline in our hospital exhibited a clinical success rate of 83.3% for carbapenem-resistant Klebsiella pneumoniae, monotherapy using moxifloxacin, piperacillin/tazobactam, cefepime, and/or ceftazidime for carbapenem-resistant Pseudomonas aeruginosa exhibited a clinical success rate of 77.7%, and monotherapy using cefoperazone/sulbactam or combination therapy with tigecycline and cefoperazone/sulbactam for carbapenem-resistant Acinetobacter baumannii exhibited a clinical success rate of 62.1%. Conclusions: Taken together, our findings highlight the clinical strategies used in our hospital to successfully treat carbapenem-resistant gram-negative bacterial infections.
