Combined effect of histological findings and diabetes mellitus on liver‐related events in patients with metabolic dysfunction‐associated steatotic liver disease

AimAdvanced fibrosis has a strong influence on the occurrence of liver‐related events in patients with metabolic dysfunction‐associated steatotic liver disease (MASLD), while diabetes mellitus (DM), which is often complicated by MASLD, is associated with the progression of MASLD. We stratified patients with MASLD according to the severity of liver pathological findings and the presence of DM, aiming to examine whether these indices could be used to accurately assess the risk of developing liver‐related events.MethodsA total of 282 patients with liver biopsy‐proven MASLD were included. Liver‐related events were defined as the occurrence of hepatocellular carcinoma (HCC) and complications of liver cirrhosis, such as ascites, hepatic encephalopathy, Child–Pugh class B and C, as well as treatment‐eligible esophageal and gastric varices.ResultsMultivariate analysis adjusted for age, sex, body mass index, alanine aminotransferase, creatinine, hemoglobin A1c, smoking habits, dyslipidemia, hypertension, nonalcoholic fatty liver disease activity score (NAS), or fibrosis stage showed that advanced fibrosis with or without DM was a risk factor for liver‐related events. The combined effect of DM and advanced fibrosis increased the risk of HCC onset. However, DM alone or in combination with NAS did not affect the development of liver‐related events, including the occurrence of HCC and complications of liver cirrhosis.ConclusionsWhile the assessment of fibrosis in patients with MASLD is important for evaluating the risk of developing liver‐related events, combining the assessment of DM may be possible to stratify groups at higher risk of developing HCC.
