The Correlation Between Liver Fat Content and Ulcerative Colitis Disease Severity

To evaluate the association between disease severity and hepatic steatosis in patients with ulcerative colitis (UC) and non-alcoholic steatohepatitis (NASH). Consecutively selected UC patients admitted to the gastroenterology clinic were enrolled in the study. UC severity was assessed by Truelove and Witts classification. Patients with severe UC were excluded from the study. NASH was determined based on persistently elevated serum aminotransferase levels and detection of fatty liver ultrasound. Patients with other etiologies for elevated aminotransferase levels were excluded. Liver fat content (LFC) was assessed by measuring liver fat score (LFS). One hundred patients (42% male) were included in the study. According to liver ultrasound examination, 62 (%) patients were identified with grade 1 fatty liver disease, and 38 (%) patients were classified as advanced (grade 2 and 3) fatty liver disease. Sixty-one patients had left-sided UC and (46%) had mild UC disease severity index. LFS was significantly higher in UC patients with the moderate disease than patients with mild disease (3.53±2.68 vs. 5.89±2.85, respectively; P
