摘      要：BACKGROUND Skeletal muscle alterations(SMAs)are being increasingly recognized in patients with metabolic dysfunctionassociated steatotic liver disease(MASLD)and appear to be associated with deleterious outcomes in these ***,their actual prevalence and pathophysiology remain to be *** To determine the prevalence of SMAs and to assess the significance of circulating myokines as biomarkers in patients with *** Skeletal muscle strength and muscle mass were measured in a cross-sectional study in a cohort of 62 patients fulfilling MASLD criteria,recruited from the outpatient clinics of a tertiary level *** degree of fibrosis and liver steatosis was studied using abdominal ultrasound and transitional *** and metabolic characteristics as well as serum levels of different myokines were also determined in the MASLD *** analysis was performed comparing results according to liver fibrosis and *** No significant differences were found in both skeletal muscle strength and skeletal muscle mass in patients with MASLD between different stages of liver ***,serum levels of fibroblast growth factor-21(FGF21)were significantly higher in patients with MASLD with advanced hepatic fibrosis(F3-F4)than in those with lower fibrosis stages(F0-F2)(197.49±198.27 pg/mL vs 95.62±83.67 pg/mL;P=0.049).In addition,patients with MASLD with severe hepatosteatosis(S3)exhibited significantly higher serum levels of irisin(1116.87±1161.86 pg/mL)than those with lower grades(S1-S2)(385.21±375.98 pg/mL;P=0.001).CONCLUSION SMAs were uncommon in the patients with MASLD *** serum levels of irisin and FGF21 were detected in patients with advanced liver steatosis and fibrosis,respectively,with potential implications as biomarkers.
