ABSTRACT
BACKGROUND:
Direct-acting antivirals (DAAs) lead to a high rate of sustained virologic response (SVR) in chronic hepatitis C infection. The aim was to evaluate liver stiffness kinetics, using acoustic radiation force impulse (ARFI) imaging elastography, during and after DAAs in patients who had reached SVR. PATIENTS ANDMETHODS:
A total of 275 consecutive chronic hepatitis C virus-infected patients were included in this longitudinal prospective single-centre study. All patients received DAAs for 8 to 24 weeks, and liver stiffness measurements (LSMs) by ARFI at baseline, at week 4, week 12, week 24, and 24 weeks (SVR24) and 48 weeks (FU48) after the end of treatment were recorded. Transient elastography was performed at baseline and at SVR24.RESULTS:
A decrease in LSM was detected at SVR24 by ARFI and transient elastography (P<0.001 and <0.001, respectively). A continuous gradual decrease in ARFI was observed in patients with cirrhosis versus a nonsignificant change in patients without cirrhosis until FU48 (P<0.001 vs. 0.877, respectively). At SVR24, higher baseline ARFI values (P=0.038) were associated with a decrease in LSM in patients with cirrhosis versus normal international normalization ratio (P=0.003), lower bilirubin (P=0.003), and higher albumin (P=0.007) in patients without cirrhosis. The incidence of liver stiffness decrease from baseline was higher in patients with cirrhosis than in those without cirrhosis (P<0.001), whereas the incidence of liver stiffness progression was more pronounced in advanced than in compensated cirrhosis (P<0.001).CONCLUSION:
After DAAs in patients with SVR, liver stiffness improves in patients with cirrhosis, whereas non-cirrhotic patients show no true change in liver stiffness. Liver stiffness worsens in patients with advanced liver disease.
