Abstract
BACKGROUND/AIM: A bioimpedance analysis (BIA) can indicate an overhydrated state as the extracellular water/total body water (ECW/TBW) value. This study aimed to assess the clinical significance of this value in patients with chronic liver diseases (CLDs). PATIENTS AND METHODS: A total of 552 CLD patients who received a liver biopsy and underwent anthropometric assessment and BIA-based body composition analysis were enrolled. The association of the ECW/TBW value with the liver fibrosis and nutritional status was assessed. The relationship between the ECW/TBW value and the prognosis of cirrhotic patients (N=209) was also evaluated. RESULTS: The ECW/TBW value increased as liver fibrosis progressed and was also related to decreased muscle mass/sarcopenia. The presence of overhydration was associated with a poor prognosis of cirrhotic patients. CONCLUSION: An increased ECW/TBW value was associated with progressive liver fibrosis and malnutrition and related to the prognosis of cirrhotic patients.
