P-57 LIVER STEATOSIS AND STEATOHEPATITIS IN LIVER DISEASES OTHER THAN ALCOHOLIC AND NON-ALCOHOLIC FATTY LIVER

Introduction: Fatty liver disease (FLD) alcoholic and non-alcoholic are prevalent conditions. The damage is determined by steatosis and steatohepatitis with or without fibrosis. There is little information on its role in the progression to significant fibrosis (SF) of chronic liver diseases (CLD) other than FLD. Objective: To describe the frequency of steatosis and steatohepatitis in liver biopsies of patients with CLD other than FLD. Methods: Observational, retrospective study with biopsies performed between 2015-2018. The presence and degree of steatosis, steatohepatitis and fibrosis were recorded according to the METAVIR scale; F3-F4 is considered SF. Results: 268 biopsies analyzed; 93 with FLD are excluded. 175 are included: 53% autoimmune hepatitis (AIH), 27% primary biliary cholangitis (PBC), 7% viral hepatitis (VH) and 13% others. 74% women; age 52 (18-82) years; 58% had steatosis and 46% had steatohepatitis; 67% fibrosis, which was SF in 61%. Steatosis/steatohepatitis/fibrosis according to etiology: AIH 34%/46%/69%; PBC 19%/9%/53%; VH 77%/15%/39%. When analyzing the presence of SF according to the presence of steatosis or steatohepatitis: in steatosis 36% vs 48% without steatosis; In steatohepatitis there were more SF (65% vs 36%; p = 0.004). According to aetiology SF/non SF: HAI 92%/38% (p = 0.001); PBC 20%/24%; VH 50%/22% (NS). Conclusion: There was a high frequency of steatosis and steatohepatitis in patients with CLD. The presence of steatohepatitis is associated with a higher degree of fibrosis in patients with CLD, particularly in AIH, which may have an impact on the evolution and treatment
