Hepatobiliary and pancreatic manifestations in inflammatory bowel diseases: a referral center study

摘要

Hepatobiliary and pancreatic manifestations have been reported in patients with Crohn’s disease or ulcerative colitis. Our aim was to describe the prevalence of hepatobiliary and pancreatic manifestations in inflammatory bowel disease and their association with the disease itself and the medications used. Data were retrospectively extracted from the clinical records of patients followed up at our tertiary IBD referral Center. Our study included 602 IBD patients, with liver function tests at regular intervals. The mean follow-up was 5.8?years (Std. Dev.: 6.72). Abdominal imaging examinations were present in 220 patients and revealed findings from the liver, biliary tract and pancreas in 55% of examined patients (120/220). The most frequent findings or manifestations from the liver, biliary tract and pancreas were fatty liver (20%, 44/220), cholelithiasis (14.5%, 32/220) and acute pancreatitis (0.6%, 4/602), respectively. There were 7 patients with primary sclerosing cholangitis. Regarding hepatitis viruses, one-third of the patients had been tested for hepatitis B and C. 5% (12/225) of them had positive hepatitis B surface antigen and 13.4% had past infection with hepatitis B virus (positive anti-HBcore). In addition, most of the patients were not immune against hepatitis B (negative anti-HBs), while 3% of patients were anti-HCV positive and only one patient had active hepatitis C. Furthermore, 24 patients had drug-related side effects from the liver and pancreas. The side effects included 21 cases of hepatotoxicity and 3 cases of acute pancreatitis. Moreover, there were two cases of HBV reactivation and one case of chronic hepatitis C, which were successfully treated. In our study, approximately one out of four patients had some kind by a hepatobiliary or pancreatic manifestation. Therefore, it is essential to monitor liver function at regular intervals and differential diagnosis should range from benign diseases and various drug related side effects to severe disorders, such as primary sclerosing cholangitis.
