PURPOSE: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a new term proposed to replace non-alcoholic fatty liver disease (NAFLD). We analyzed the ultrasonographic findings of MAFLD and NAFLD.
METHODS: We conducted a retrospective cross-sectional study of subjects aged ≥19 years who underwent a health screening examination, including ultrasonography, (n = 17,066). Patients were separated into one of three groups; pure MAFLD (n = 5304), pure NAFLD (n = 579), and both NAFLD & MAFLD (n = 11,183). The outcomes were the degree of fatty liver disease and liver cirrhosis, defined by ultrasonography. In addition, the risk of ultrasonographic cirrhosis was assessed in the MAFLD group based on clinical characteristics.
RESULTS: The pure NAFLD group had a lower risk of severe fatty liver disease than the both NAFLD & MAFLD groups (0.9 % vs. 4.4 %, p < 0.001). Cirrhosis was not diagnosed in the NAFLD group. Cirrhosis was more common in the pure MAFLD group than in the both NAFLD & MAFLD group (0.3 % vs. 0.0 %, p < 0.001). In the MAFLD group, multivariable analysis showed that diagnosis by hepatic steatosis index (Odds ratio [OR], 12.39; 95 % confidence interval [CI], 3.40-45.19; p < 0.001) or significant alcohol intake (OR, 9.58, 95 % CI, 1.93-47.61; p = 0.006) was independently associated with risk of liver cirrhosis on ultrasonography.
CONCLUSION: Liver cirrhosis was more frequently identified on ultrasonography in patients with MAFLD than in NAFLD. MAFLD diagnosed using the hepatic steatosis index or significant alcohol intake is a risk factor for liver cirrhosis.
