Nonalcoholic fatty liver disease in patients with inflammatory bowel disease: Beyond the natural history

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a frequently reported condition in patients with inflammatory bowel disease (IBD). Both intestinal inflammation and metabolic factors are believed to contribute to the pathogenesis of IBD-associated NAFLD. AIM: To evaluate the prevalence of steatosis and liver fibrosis (LF) in a cohort of IBD patients and the identification of metabolic- and IBD-related risk factors for NAFLD and LF. METHODS: IBD patients were consecutively enrolled from December 2016 to January 2018. Demographic, anthropometric and biochemical data were collected so as eating habits. Abdominal ultrasound and transient elastography were performed to evaluate the presence of NAFLD and LF respectively. CONCLUSION: In this study, we demonstrate that risk factors for NAFLD and LF in the IBD population do not differ from those in the general population.
