Abstract

Background: Presarcopenia is a common complication of chronic liver disease. However, the relationship between serum zinc concentration and presarcopenia in patients with chronic liver disease remains unclear. Herein, we examined whether serum zinc concentration could predict presarcopenia in patients with chronic liver disease.

Methods: Between October 2015 and December 2019, 278 patients with chronic liver disease (median age, 68 years; women/men, 133/145; hepatitis B virus/hepatitis C virus/negative hepatitis B surface antigen and negative anti-hepatitis C virus antibody, 55/124/99) who underwent abdominal computed tomography (CT) and simultaneous measurement of serum zinc concentration were included. Zinc deficiency and subclinical zinc deficiency were classified using serum zinc concentration cutoff values of <60 and <80 μg/dL [based on the Japanese Society of Clinical Nutrition (JSCN) guidelines], respectively. Additionally, presarcopenia was evaluated based on the skeletal muscle mass as per the Japan Society of Hepatology (JSH)'s sarcopenia criteria.

Results: Univariate analysis revealed that the following factors were significantly associated with the presence of presarcopenia in patients with chronic liver disease: age (P<0.001), male sex (P<0.001), body mass index (BMI) (P<0.001), serum zinc concentration (P=0.005), fibrosis-4 index (P<0.001), and serum albumin concentration (P=0.03). Additionally, the median L3 skeletal muscle indices were as follows: men, non-presarcopenia group/presarcopenia group, 47.56/37.91 cm²/m² (P<0.001); women, non-presarcopenia group/presarcopenia group, 41.64/32.88 cm²/m² (P<0.001). Multivariate analysis using logistic regression analysis revealed that male sex [odds ratio (OR), 0.194; 95% confidence interval (CI): 0.089-0.419; P<0.001], BMI (OR, 0.666; 95% CI: 0.582-0.761; P<0.001), and serum zinc concentration <60 μg/dL (OR, 5.930; 95% CI: 1.480-23.80; P=0.01) were factors associated with presarcopenia. The OR for serum zinc concentration between 60 and 80 μg/dL was 1.910 (95% CI: 0.824-4.420; P=0.13).

Conclusions: Low serum zinc levels may be an independent predictor of presarcopenia in patients with chronic liver disease.
