Background
The outcome of patients with chronic hepatitis C virus infection (HCV) and advanced, compensated liver disease after sustained virological response (SVR) to direct‐acting antivirals (DAAs) has not yet been completely depicted. We aimed to assess the clinical, biochemical and instrumental outcome of patients with advanced, compensated chronic HCV‐related liver disease with DAA‐induced SVR to DAAs and who had at least 1‐year follow‐up.
Materials and methods
Fifty‐two patients with cirrhosis (n = 27) and fibrosis stage F3 (n = 25) followed up for a median of 60 weeks after successful DAA treatment were included. Laboratory work‐up, including APRI and FIB‐4 scores, liver transient elastography and measurement of the spleen bi‐polar diameter were carried out before treatment and at the end of follow‐up.
Results
Liver stiffness decreased (P < 0.0001) from a median baseline of 15.2 kPa (12.0‐20.0) to 9.3 kPa (7.5‐12.0) at follow‐up. A liver stiffness value suggestive of the presence (ie, ≥21.0 kPa) of clinically significant portal hypertension was found in 13 patients (25.0%) at baseline and in seven patients (13.5%) at follow‐up (P = 0.037). Both APRI (P < 0.0001) and FIB‐4 score (P = 0.025) progressively decreased, while platelet count increased (143 × 109/L [117‐176] to 153 × 109/L [139‐186], P = 0.003), and spleen bi‐polar diameter decreased (120 mm [112‐123] to 110 mm [102‐116], P = 0.0009) from baseline to the end of follow‐up.
Conclusions
In patients advanced, compensated chronic liver disease, liver stiffness significantly improves in the long‐term after SVR, and this improvement is accompanied by an amelioration of indirect indices of liver fibrosis and function, and by a decrease in parameters of portal hypertension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
