Prevalence and determinants of hepatic steatosis and fibrosis due to metabolic dysfunction–associated steatotic liver disease (MASLD) in newly diagnosed type 2 diabetes mellitus
摘要
Early detection of metabolic dysfunction-associated steatotic liver disease (MASLD) in newly-diagnosed type 2 Diabetes Mellitus (T2DM), despite offering a therapeutic window, is not extensively studied.
ObjectiveThe study aimed to define the prevalence and determinants of MASLD in patients with newly diagnosed T2DM.
MethodsConsecutive patients with newly diagnosed T2DM (≤ 6 months) were enrolled at a tertiary care center and non-invasive hepatic indices were utilized to assess MASLD: hepatic steatosis index (HSI), aspartate aminotransferase to platelet ratio index (APRI), fibrosis 4 index (FIB4), and nonalcoholic fatty liver disease fibrosis score (NFS), along with Fibroscan in a subset of the patients.
ResultsA total of 298 newly diagnosed T2DM patients were included, with a mean age of 51.6 ± 11.5 years. Hepatic steatosis was present in 69.7% and fibrosis in 10% of the cohort, with elevated APRI (5.2%) and NFS (13.1%). Hepatic steatosis was strongly correlated with BMI (r = 0.79, p = 0.00). Both FIB4 and APRI showed significant positive correlation with aspartate transaminase and negative correlation with platelets (p < 0.05). High BMI predicted hepatic steatosis (adjusted OR 2.8, 95% CI 1.25 to 6.65, p = 0.012) while AST (adjusted OR 1.1, 95% CI 1.10 to 1.23, p = 0.00) predicted fibrosis.
ConclusionThere is a significant prevalence of MASLD in newly diagnosed T2DM. Non-invasive tests are valuable, with high sensitivity (steatosis index) and specificity (fibrosis indices).
