Background
Intestinal mucosal injury is supposed to cause liver disease and inflammatory bowel disease (IBD), Crohn’s disease (CD) and ulcerative colitis (UC) is a typical chronic injury of intestinal mucosa. Therefore, we investigated the hepatobiliary manifestation with liver ultrasonography (LUS) and vibration-controlled transient elastography (VCTE) in IBD.
Methods
IBD patients newly diagnosed in Kosin University Gospel Hospital were enrolled consecutively. Gross hepatobiliary abnormality was evaluated with LUS and simultaneous liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) were assessed to evaluate hepatic injury and steatosis with VCTE. Laboratory tests including hepatic biochemistries, anti-nuclear antibody (ANA), and faecal calprotectin level (FC) were taken.
Results
Eighty-two (37 patients of CD and 45 UC) patients were enrolled. Gallbladder abnormality was noted in 39 patients (47.5%) including stone in 7, sludge in 11, polyp in 10, wall thickening in 9 and collapsed in 2. CAP >233 dB/m was in 33 patients (40.2%) and LSM >5.5 kPa in 10 (12.2%). Nineteen patients (23.2%) were diagnosed fatty liver. FC was 382 ± 785 (mean ± SD). CAP >233 dB/m was significantly associated with lower FC (209.6 vs. 352.1,
Conclusion
In this prospective analysis, the major hepatobiliary manifestations in IBD patients were gallbladder abnormality and fatty liver and there could be an association between low hepatic fat amount and intestinal disease activity.
