| Abstract: | BACKGROUND: Factors that determine individual disease course of patients with primary sclerosing cholangitis (PSC) are poorly understood. Although an association between gut microbes and disease outcome has been suggested, little is known about the role of microbes in the biliary tract. METHODS: We analyzed microbial cultures from bile specimens obtained during routine endoscopic retrograde cholangiopancreatography (ERCP) and intraoperatively before liver transplantation in 114 patients with PSC in our tertiary academic center. The presence of bacterial and fungal species was correlated with clinical characteristics and outcome data. RESULTS: A total of 87 patients (76%) had positive bile culture results. The presence of concomitant inflammatory bowel disease (IBD) was associated with positive bile culture results in multivariate analysis (OR, 4.707; 95% CI, 1.688-13.128; p=0.003). Enterococcus spp. in the bile was associated with a more frequent occurrence of liver transplantation and/or death (OR, 2.778; 95% CI, 1.147-6.728; p=0.021) and recurrent (≥3) cholangitis episodes (OR, 2.839; 95% CI, 1.037-7.768; p=0.037). Biliary candidiasis was linked to a higher frequency of recurrent (≥3) cholangitis episodes (OR, 5.677; 95% CI, 1.940-16.616; p=0.001). Proton pump inhibitor intake conferred a clinical feature associated with biliary candidiasis in multivariate analysis (OR, 3.559; 95% CI, 1.275-9.937; p=0.016). CONCLUSIONS: Our data indicate that in patients with PSC, presence of Enterococcus spp. and Candida spp. in bile is associated with an adverse outcome. Concomitant IBD is linked to presence of microbes in bile, and proton pump inhibitor intake is a feature associated with biliary candidiasis in patients with PSC. |
