Introduction:

Sarcopenia is a frequent complication of cirrhosis and has been related to the progression of liver failure and increased complications, including mortality. This study aimed to determine the factors associated with muscle mass and strength in cirrhotic patients.

Materials and methods:

Cross-sectional, descriptive, analytical study. All adults who attended outpatient hepatology assessment with a diagnosis of liver cirrhosis were included. They underwent a nutritional examination that included anthropometric measurements, bioimpedanciometry, grip strength, and the Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) screening scale. A linear or logistic regression analysis was performed as appropriate.

Results:

40 patients were included. The frequency of malnutrition was 17.5%, according to grip strength. The main determinants of muscle mass in the multivariate linear analysis were age, total body protein value, and total body water. Grip strength was also a significant predictor in univariate linear regression. Variables related to decreased muscle strength were the Child-Pugh score, history of ascites and hepatic encephalopathy, consumption of ammonium-lowering therapies, RFH-NPT score, and fat-free mass.

Conclusions:

The skeletal muscle mass of the cirrhotic patient was associated with age, changes in body composition, and grip strength. The muscle strength determinants were the disease’s stage, the consumption of ammonium-lowering therapies, and the score on the RFH-NPT scale.
