Abstract
OBJECTIVES
Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is an emerging disease entity with unfavourable outcome. Our aim was to analyze the microbial spectrum in bile of patients with SSC-CIP and to evaluate the potential impact on the empiric antibiotic treatment in these patients.
METHODS
169 patients (72 patients with SSC-CIP and 97 patients with primary sclerosing cholangitis (PSC)) were included in a prospective observational study between 2010 and 2013. Bile was obtained during endoscopic retrograde cholangiography (ERC) and microbiologically analyzed.
RESULTS
Patients with SSC displayed a significantly different microbiological profile in bile. Enterococcus faecium, Pseudomonas aeruginosa and non-albicans species of Candida were more frequent in SSC compared to patients with PSC (p < 0.05). Patients with SSC showed a higher incidence of drug or multi-drug resistant organisms in bile (p = 0.001). The antimicrobial therapy was adjusted in 64% of patients due to resistance or presence of microorganisms not covered by the initial therapy regimen.
CONCLUSIONS
Patients with SSC-CIP have a distinct microbial profile in bile. Difficult to treat organisms are frequent and an ERC with bile fluid collection for microbiological analysis should be considered in case of insufficient antimicrobial treatment.
