Background: The incidence of metabolic dysfunction- associated fatty liver disease (MAFLD) is rising in parallel with increasing bodyweight and loss of glucose control, implicating a high risk of hepatic and extra-hepatic complications. Subjects / Methods: This longitudinal observational study analysed several indicators for MAFLD in 240 overweight subjects (body mass index (BMI) > 28 kg/m²) at 2 visits within in average 16 months. Subjects were categorised according to their insulin sensitivity (HOMAIR) and diabetic status. Methods: Liver fat and liver stiffness were measured with sonographic elastography (FibroScan®), and by calculation of Fatty Liver Index (FLI), and NAFLD Fibrosis Score (NFS). Results: Parameters indicative for liver steatosis, i.e., the controlled attenuation parameter (CAP) and the FLI, were significantly higher in the T2DM group compared to the normal glucose tolerance (NGT) and impaired glucose tolerance (IGT) groups (pIRsignificantly correlated with sonographic liver fat content (CAP) (r=0.53, pIRscore increased mainly driven by the group of obese subjects with T2DM. No significant change in liver fat or stiffness was observed that period. Conclusions: In subjects with a BMI ≥ 28kg/m², the prevalence of MAFLD increases in line with increasing insulin resistance and loss of glucose control. Despite some further deterioration in insulin sensitivity, liver fat content appeared relatively unchanged over 16 months. |
