ABSTRACT
Objective@#o investigate the features of pathogenic bacteria for community-acquired bloodstream infection due to Gram-negative bacilli in patients with liver cirrhosis and optimal therapeutic strategy.@*Methods@#A retrospective analysis was performed for the clinical data of patients with liver cirrhosis who were admitted to 302 Hospital of PLA due to community-acquired bloodstream infection from January 2010 to December 2015, and a statistical analysis was performed for their clinical features, pathogenic bacteria, and results of drug sensitivity test. The Pearson chi-square test was used for comparison of rates, and the Wilcoxon rank sum test was used for comparison of ranked data.@*Results@#A total of 240 patients (including 178 male patients) with liver cirrhosis caused by various reasons were enrolled, with a mean age of 51.7 ± 11.1 years, an overall clinical remission rate of 80.42%, and an ineffective/mortality rate of 19.58%. The patients who used sensitive antibiotics within 12 hours after the onset of community-acquired bloodstream infection achieved a significantly higher improvement rate than those who used such drugs at more than 12 hours after onset (88.2% vs 58.1%, P < 0.001). The improvement rate achieved by the application of sensitive antibiotics at more than 12 hours after onset decreased with the increase in the Child-Pugh grade (P < 0.05). A total of 245 strains of Gram-negative bacilli were isolated, among which the six most common ones were 135 strains of Escherichia coli (55.1%), 62 strains of Klebsiella pneumoniae (25.3%), 16 strains of Aeromonas (6.5%), 4 strains of non-typhoidal Salmonella (1.6%), 3 strains of Enterobacter cloacae (1.2%), and 2 strains of Acinetobacter baumannii (0.8%). These Gram-negative bacilli had the highest sensitivity to meropenem (98.5%), followed by imipenem (97.9%), amikacin (97.5%), piperacillin/tazobactam (94.7%), cefmetazole (93.7%), and cefoperazone/sulbactam (93%). Different bacteria had different sensitivities to antibiotics.@*Conclusion@#Once community-acquired bloodstream infection occurs in patients with liver cirrhosis, highly sensitive antibiotics should be used as early as possible. Cefoperazone/sulbactam, piperacillin/tazobactam, imipenem, and meropenem can be used as first-line empirical antibiotics, and drug combination should be considered when necessary.
