Liver stiffness is influenced by a standardized meal in patients with chronic hepatitis C virus at different stages of fibrotic evolution

2013 Hepatology 58;1 (65-72)

Transient elastography (TE) is increasingly employed in clinical practice for the noninvasive detection of tissue fibrosis in patients with chronic liver disease (CLD), and particularly chronic hepatitis C virus (HCV)-related hepatitis. The present study was designed to provide a definitive characterization of the "confounding" increase in liver stiffness (LS) following a standardized meal in a consecutive population of 125 patients with chronic HCV infection at different stages of fibrotic evolution. LS values were obtained after overnight fasting and 15, 30, 45, 60, and 120 minutes following the onset of a standardized liquid meal (400 mL, 600 Kcal, 16.7% protein, 53.8% carbohydrates, 29.5% fat). An evident increase in LS values was observed 15 to 45 minutes after the onset of the meal with return to baseline premeal levels within 120 minutes in all patients. The peak postmeal delta increase in LS was progressively more marked with increasing stages of fibrosis (P
