Arm Skeletal Muscle Mass Is Associated With the Prognosis of Patients With Cirrhosis

Background/Aim: This study aimed to assess the clinical significance of measuring the arm skeletal muscle mass in patients with cirrhosis. Patients and Methods: Using body composition data measured with the bioimpedance analysis (BIA) method, the skeletal muscle mass index (SMI) values of the arm (arm skeletal muscle mass/height(2)) and leg (leg skeletal mass muscle/height(2)) were calculated for 353 patients with cirrhosis, and the relationships of these indices to their prognosis were assessed. In addition, overhydration of the upper and lower limbs was compared. Results: Arm SMI was significantly positively associated with the prognosis of patients with cirrhosis (p=0.0002) but leg SMI was not (p=0.0829). The rate of overhydration in the lower limbs was significantly higher than that in the upper limbs (p
