Backgrounds: Malnutrition and sarcopenia are prevalent complications in cirrhosis. The relationship between sarcopenia and biliary infection in cirrhotic patients is not well understood. Our study aims to clarify this association.
Methods: In this study, we leveraged data from a tertiary care hospital, enrolling patients with hepatitis B virus (HBV)-induced cirrhosis from 2022. An acute biliary tract infection was defined as the onset of acute cholecystitis or cholangitis within a year. Sarcopenia was identified based on established criteria and assessed using the L3 skeletal muscle index (SMI). A multivariate logistic regression model was constructed to analyze the relationship between sarcopenia and acute biliary tract infection. Receiver operating characteristic (ROC) curve analysis and smooth curve fitting were also conducted.
Results: This study enrolled a total of 262 patients with HBV-related cirrhosis, with an average age of 60 years and including 173 males. The primary causes for hospital admission were ascites and hepatic encephalopathy. Within the group with biliary infection, patients typically presented with higher white blood cell counts, lower platelet levels, and poorer indicators of liver and kidney function. In the multivariate analysis, after adjusting for various confounding factors, sarcopenia was associated with an odds ratio of 1.55 ( P = 0.002) for acute biliary infection. Smooth curve fitting revealed an approximately linear positive relationship between L3 SMI and acute biliary infection, with the area under the ROC curve for L3 SMI reaching 0.89, indicating a strong predictive value.
Conclusion: Sarcopenia is associated with acute biliary infection in patients with HBV-related cirrhosis.
