BACKGROUND: Sarcopenia is highly prevalent in patients with liver cirrhosis and contributes to decreased quality of life, increased morbidity, and mortality. The role of myostatin in cirrhosis-related sarcopenia remains controversial but may represent a potential therapeutic target.
OBJECTIVE: This study aimed to investigate the association between serum myostatin levels and sarcopenia in patients with liver cirrhosis.
METHODS: A cross-sectional study was conducted with 80 patients diagnosed with liver cirrhosis at Prof. Dr. I.G.N.G. Ngoerah General Hospital, Denpasar, Bali, Indonesia. Serum myostatin levels (ng/L) were measured using an ELISA technique. Sarcopenia was diagnosed based on the 2019 Asian Working Group for Sarcopenia (AWGS) consensus. Elevated myostatin levels were defined as values above the median. Bivariate and multivariate analyses were performed to assess associations between myostatin, cirrhosis severity, and sarcopenia.
RESULTS: The severity of cirrhosis (CTP B and C) was associated with elevated myostatin levels (PR = 2.046; 95% CI: 1.310-3.193; p = 0.002). Bivariate analysis demonstrated that elevated myostatin (PR = 2.178; 95% CI: 1.370-3.461; p <0.001), CTP B and C (PR = 1.818; 95% CI: 1.223-2.701; p = 0.004), ascites (PR = 1.606; 95% CI: 1.110-2.324; p = 0.034), and malnutrition (PR = 1.806; 95% CI: 1.242-2.626; p = 0.004) were associated with sarcopenia. In multivariate analysis, only elevated serum myostatin remained significantly associated with sarcopenia (AOR = 4.273; 95% CI: 1.557-11.724; p = 0.005).
CONCLUSION: Elevated serum myostatin levels are strongly associated with sarcopenia in patients with liver cirrhosis. Cirrhosis severity is also linked to higher myostatin levels, suggesting a potential role for myostatin-targeted interventions in sarcopenia management.
