Abstrakt: Background/aim: Sarcopenia and myosteatosis are common in patients with cirrhosis. The study aimed to evaluate efficacy of ultrasound to monitor muscle status during branched-chain amino acid (BCAA) supplementation and/or muscle exercise interventional approaches.
Patients and Methods: A randomized controlled study, included 220 liver cirrhosis patients with Child- Pugh B and C, randomized into a control group (55 patients) received only the standard care, and interventional groups (165 patients) equally distributed into three subgroups, in addition to standard care, they received BCAA, programmed exercise, or BCAA and programmed exercise. At baseline and after 28 days, all participants were subjected to ultrasound-measured quadriceps muscle thickness and echo-intensity, muscle strength using handgrip, performance using short physical performance battery (SPPB), Model for End-Stage Liver Disease (MELD) score and nutritional assessment using 7- point Subjective Global Assessment Score (SGA) and laboratory assessment.
Results: All interventional groups showed a significant improvement in the ultrasound detected quadriceps muscle thickness (p = 0.001) and echo intensity, in addition to muscle strength, muscle performance, and SGA. Hematological parameters (hemoglobin and platelet count), biochemical parameters (ALT, AST, bilirubin, creatinine, urea and INR) and MELD score were also improved in the interventional groups. In Child-Pugh B patients BCAA combined with exercise showed an add-on effect.
Conclusion: BCAA supplements, programed muscle exercise and both are useful interventional methods in improving muscle quality and quantity in cirrhosis patients, which can be monitored by ultrasound. The best results can be achieved by combined intervention in Child-Pugh B, while in Child-Pugh C single intervention may lead to an acceptable improvement. The trial was registered retrospectively in the Clinical Trials Registry (registration number NCT06088550).
