Abstract
The purpose of this study was to explore the correlation between Hashimoto's thyroiditis and Metabolic dysfunction-associated fatty liver disease (MAFLD), and at the same time to screen high-risk groups for liver fibrosis in MAFLD, find out the high-risk related indicators. The physical examination population was included as the study subjects and was grouped according to the diagnostic criteria for MAFLD. APRI > 1 or NFS > 0.676 or FIB-4 > 2.67were used to assess people at high risk of liver fibrosis, and logistic regression analysis was used to identify risk factors associated with high risk of liver fibrosis in MAFLD. ROC curves are used to look for indicators of diagnostic value. The proportion of people with Hashimoto's thyroiditis was lower in the MAFLD group. The MAFLD high-risk group for liver fibrosis had higher TSH levels, lower FT3 and FT4 levels, higher TGAB levels, and differences in biochemical markers. Age, BMI, FBG, and AST are risk factors for the high risk of liver fibrosis in MAFLD patients. ROC curve analysis showed that the AUC of age was 0.741 (0.721-0.761), and the optimal stage value was 57.5 years, while the AUC of AST was 0.729 (0.707-0.751), and the optimal cut-off value was 39.5 U/L. Age, BMI, FBG, and AST are risk factors for the high risk of liver fibrosis in MAFLD patients.The age is greater than or equal to 57.5 years, or the AST is greater than or equal to 39.5 U/L, indicating that the MAFLD patients are at high risk of liver fibrosis.
