Background/Aims: This study assessed the antibiotic resistance organisms isolated from the blood and bile of acute cholangitis and evaluated risk factors associated with them and their impact on clinical outcomes.
Methods: The identities and antibiotic resistance profiles of bacteria isolated from 433 cases of acute cholangitis from 346 patients were analyzed. Risk factors and the outcomes of patients infected with them were assessed.
Results: Microorganisms were isolated from 266 of 419 blood cultures and 256 of 260 bile cultures. Isolates from bile and blood were identical in 71% of the cases. A total of 20 extended spectrum-β-lactamase (ESBL)-producers and 4 carbapenemase-producing organisms were isolated from blood, and 34 ESBL-producers and 13 carbapenemase-producers were isolated from bile. Sixty-four (14.8%) cases were infected with any one of these bacteria isolated from blood or bile. Risk factors associated with them in blood were nosocomial infection and prior biliary intervention. In bile, indwelling biliary device was a risk factor associated with them. Antibiotic-resistant bacteria were associated with mortality, independent of other prognostic factors.
Conclusions: ESBL or carbapenemase-producing bacteria were frequently isolated in acute cholangitis patients especially with prior biliary intervention and nosocomial infection. Isolation of antibiotic-resistant bacteria was an independent risk factor of mortality.| 번호 | 참고문헌 | 국회도서관 소장유무 |
