Abstract:

Objective

To define the microbial epidemiology and outcome of Extended-spectrum β-lactamases (ESBLs) -producing Klebsiella spp. and Escherichia coli in bloodstream infections (BSI) after liver transplantation.

Methods

From January 1998 to December 2009, a retrospective analysis of ESBLs-producing Klebsiella spp. and Escherichia coli were conducted.

Results

BSI occurred in 19 (2.5%) patients of the 768 patients, in which a total 23 gram-negative bacilli (GNB) were isolated. The most frequent pathogens were Escherichia coli and Klebsiella spp. enterobacter cloacae, pseudomonas aeruginosa, Enterobacter aerogenes were few. Carbapenems were the most consistently active against the Escherichia coli and Klebsiella spp which were resistant to ceftriaxone. No significance in 15-day, 30-day, 1-year mortality between ESBL-producing and non-ESBL-producing Klebsiella spp. and Esche-richia coli.

Conclusion

ESBL-producing Klebsiella spp. and Escherichia coli after liver transplantion are resistant to agents but active to Carbapenems commonly, which can not increase 15-day, 30-day, 1-year mortality simultneously.
