  •   Objective  To investigate the incidence rate of sarcopenia in patients with Wilson’s disease (WD)-related liver cirrhosis, as well as the risk factors for sarcopenia and their impact on clinical outcomes.  Methods  A total of 140 patients with WD-related liver cirrhosis who were treated in The First Affiliated Hospital of Anhui University of Chinese Medicine from January 2019 to June 2020, and according to the third lumbar skeletal muscle mass index (L3 SMI), the patients were divided into sarcopenia group and non-sarcopenia group. Nutritional risk screening, anthropometric measurements, and blood biochemical tests were performed for the patients to identify the influencing factors for sarcopenia. The patients were followed up for 36 — 48 months, and survival status and complications were compared between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the chi-square test and the Mann-Whitney U rank sum test were used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for sarcopenia, and univariate and multivariate Cox regression analyses were used to investigate the risk factors for the prognosis of patients with WD-related liver cirrhosis. The Kaplan-Meier survival curve was plotted, and the Log-rank test was used for comparison between groups.  Results  Among the 140 patients with WD-related liver cirrhosis, 53 (37.9%) developed sarcopenia, with significantly lower body mass index (BMI) and L3 SMI than the patients without sarcopenia (t=10.550 and 3.982, both P<0.001). The multivariate Logistic regression analysis showed that age (odds ratio [OR]=2.243, 95% confidence interval [CI]: 1.196 — 4.208, P=0.012), sex (OR=0.450, 95%CI: 0.232 — 0.872, P=0.018), BMI (OR=0.126, 95%CI: 0.089 — 0.294, P<0.001), and hepatic encephalopathy (OR=8.367, 95%CI: 2.423 — 28.897, P<0.001) were the main influencing factors for sarcopenia in patients with WD-related liver cirrhosis. Compared with the non-sarcopenia group, the sarcopenia group had significantly higher mortality rate (χ2=6.158, P=0.019) and significantly higher incidence rates of infection (χ2=8.008, P=0.040), recurrent abdominal/pleural efflux (χ2=17.742, P<0.001), and hepatic encephalopathy (χ2=4.338, P=0.039). The multivariate Cox regression analysis showed that sarcopenia (hazard ratio [HR]=4.685, P=0.002) and hepatic encephalopathy (HR=19.156, P<0.001) were independent risk factors for death in patients with WD-related liver cirrhosis. The Kaplan-Meier survival curve analysis showed a significant reduction in survival rate in the patients with sarcopenia (P=0.003).  Conclusion  Sarcopenia is one of the manifestations of malnutrition in patients with WD-related liver cirrhosis, which increases the risk of mortality and other complications and has an adverse effect on prognosis. There is an increased risk of sarcopenia in male patients or patients with hepatic encephalopathy, a lower level of BMI or an older age.
