Abstract
AbstractAimThis study aimed to elucidate a surrogate marker of sarcopenia in patients with liver cirrhosis (LC).MethodsA total of 424 patients were assessed for handgrip strength (HGS) and skeletal muscle index (SMI). They were divided into two groups: sarcopenia (Group S; n = 80) and nonsarcopenia (Group NS; n = 344).ResultsGroup S showed significantly lower HGS, SMI, and hemoglobin (Hb) levels in males and female patients, and lower serum levels of albumin, cholinesterase, and zinc (all p < 0.001), along with significantly higher serum levels of procollagen type III‐N‐peptide and type IV collagen 7S‐domain (p < 0.001 and p < 0.0017) than Group NS. The risk factors for sarcopenia were age 65 years or older, female gender, Child–Pugh class C, and Hb levels <10.9 g/dL in women and <12.4 g/dL in men (p = 0.012, p < 0.001, p = 0.031, and p < 0.001, respectively). Significant positive correlations were found between the Hb level and the SMI and HGS (r = 0.4, p < 0.001 and r = 0.4, p < 0.001, respectively). Sarcopenia, low HGS, and low SMI were significantly associated with overall survival in patients with LC (all p < 0.001). The predictive accuracy of Hb levels for predicting sarcopenia was significantly higher than for predicting SMI and tended to be higher than for predicting HGS (p = 0.014 and p = 0.059, respectively).ConclusionHemoglobin levels are predictive of sarcopenia in patients with LC and warrants further investigation as a biomarker for sarcopenia in LC.
