Characteristics of L3 Skeletal Muscle Index and Its Predictive Value for Nutritional Status in Patients with Cirrhosis of Different Etiology
Objective:To explore the characteristics of L3 skeletal muscle index in patients with cirrhosis of different etiology and its predictive value for nutritional status of patients.Methods:120 patients with cirrhosis admitted to our hospital from June 2019 to June 2022 were selected for the study,including 40 cases of hepatitis B cirrhosis,40 cases of alcoholic cirrhosis,and 40 cases of liver cirrhosis with autoimmune hepatitis.Compthe L3 SMI characteristics of hepatitis B cirrhosis,alcoholic cirrhosis,and autoimmune hepatitis cirrhosis.Pearson correlation test was used to analyze the correlation between L3 SMI and nutritional status in patients with cirrhosis.The independent risk factors affecting the nutritional status of cirrhosis were established by Logistics regression model.The predictive value of L3 SMI for nutritional status in cirrhosis was evaluated using receiver operating curve(ROC).Results:The expression levels of L3 SMI,25(OH)D,ALB,PA and TRF in autoimmune hepatitis cirrhosis group were significantly lower than those in alcoholic cirrhosis group and hepatitis B cirrhosis group(P<0.05),and alcoholic cirrhosis group was significantly lower than that in hepatitis B cirrhosis group(P<0.05).LSM was significantly positively correlated with 25(OH)D,ALB,PA and TRF in patients with cirrhosis(P<0.05).The nutritional status of patients with cirrhosis was incorporated into logistics regression model as dependent variable(normal nutrition=0,malnutrition=1).The results showed that 25(OH)DALB,PA,TRF and L3 SMI were risk factors(P<0.05).The results of multivariate analysis showed that 25(OH)DALB,PA,TRF and L3 SMI were independent risk factors affecting the nutritional status of patients with cirrhosis(P<0.05).L3 SMI predicted the Youden index of 0.765,sensitivity 85.00(%),specificity 82.00(%),AUC value 0.810,95%CI:0.685~0.912.Conclusion:There are significant differences in L3 skeletal muscle index in patients with cirrhosis of different etiology,and L3 skeletal muscle index can be used in clinical prediction and evaluation of nutritional status in patients with cirrhosis.
