Coexistence of Primary Biliary Cirrhosis and Inflammatory Bowel Disease

The coexistence of Primary Biliary Cirrhosis (PBC) and Inflammatory Bowel Disease (IBD) is uncommon, although hepatobiliary complications in IBD patients are not rare. This report reviews the English and Japanese literature and covers reported cases of concomitant PBC and IBD. We identified 2 cases of concomitant PBC and Crohn’s Disease (CD) and 18 cases of concomitant PBC and Ulcerative Colitis (UC). In most instances (15/18), IBD (CD or UC) developed before PBC, with the exception of 2 cases that were almost simultaneously diagnosed with both conditions. There is no evidence that UC cases with concomitant PBC are more severe than those without; however, the clinical features of concomitant PBC and CD are unclear due to few reports.
