Metabolic associated fatty liver disease better identifying patients at risk of liver and cardiovascular complications (original) (raw)
Abstract
Background/purpose
A nomenclature of “metabolic associated fatty liver disease” (MAFLD) with a new definition was proposed in 2020 instead of the previous “non-alcoholic fatty liver disease” (NAFLD). Whether it better coheres with the clinical demand remains controversial.
Methods
The participants with fatty liver on ultrasonography in Taiwan bio-bank cohorts were included. MAFLD is defined as the presence of fatty liver, plus any of the following three conditions: overweight/obesity, type 2 diabetes mellitus (DM), or metabolic dysfunction. The severity of liver fibrosis was determined using fibrosis-4 (FIB-4) index and NAFLD fibrosis score (NFS). The risk of atherosclerotic cardiovascular disease was assessed using intima–media thickness (IMT) or plaques of carotid duplex ultrasound.
Results
A total of 9,719 subjects (ages 55.9 ± 10.8; males 42.6%) were distributed among 4 groups: “overlapping group”, “MAFLD only”, “NAFLD only”, and “neither fatty liver disease (FLD)” with the percentages of 79.7, 12, 7.1, and 1.2%, respectively. Compared with NAFLD patients, MAFLD patients had a greater percentage of males, higher levels of BMI, waist circumference, HbA1c, and triglyceride. In addition, they had higher levels of serum ALT, AST, GGT, fatty liver index (FLI), NFS, and IMT, but no difference in FIB-4 index and the percentage of carotid plaques. To note, “MAFLD only group” had greater levels of AST, ALT, GGT, FLI, FIB-4, NFS, IMT and a higher percentage of carotid plaques than the “NAFLD only group”.
Conclusion
The grand, population-based study showed MAFLD with new diagnostic criteria to aid in identifying a greater number of high-risk patients of metabolic, liver, and cardiovascular complications, suggesting MAFLD may be a better nomenclature than NAFLD in clinical practice.
