278-LB: Type 2 Diabetes (T2D) as a Risk Factor for NASH and Significant Liver Fibrosis (F>2) in an International Cohort of 2,363 Patients with Metabolic Steatosis

Background and Aim: T2D increases the prevalence of steatosis and steatohepatitis (NASH). The aim was to assess the relationship between T2D and two histological features of liver injury defining the need for therapy: disease activity grade (NAS) and fibrotic scar (F). Methods: 2363 patients with metabolic steatosis were screened for the phase 3 elafibranor trial RESOLVE-IT (NTC02704403) with a liver biopsy centrally scored for NAS and F. 71% had obesity, 47% dyslipidemia, 81% MetS. 35% had T2D, 88% of them managed by ≥1 OAD or insulin. Prevalence of active disease (NAS≥4), significant fibrosis (F≥2) and progressive NASH (NAS≥4 with F≥2, i.e., "at-risk" of hepatic outcomes) and clinical and biochemical NASH phenotype was assessed according to the T2D status. Results: The overall prevalence of "at-risk" NASH was 53%, 65% for T2Ds (n=835), and 45% for non-T2Ds (n=1528). T2D was a significant risk factor (p Conclusion: In patients with metabolic steatosis, T2D is associated with necroinflammation and fibrosis and independently increases the risk of developing “at-risk” NASH, highlighting the need for active surveillance of liver injury in T2D patients to identify those in need for clinical intervention.
