Long-term changes in liver elasticity in hepatitis C virus-infected patients with sustained virologic response after treatment with direct-acting antivirals.
2018
BackgroundThe use of interferon-free direct-acting antiviral agents (DAAs) is associated with a rapid short-term decrease in liver stiffness in chronic hepatitis C-infected patients with sustained virologic response (SVR).ObjectiveThe objective of this article is to evaluate long-term changes in liver elasticity in hepatitis C patients with SVR using transient elastography (TE), FIB-4 and APRI.MethodsA total of 143 patients were treated with DAAs and reached SVR. Patients received TE measurement (median (range)) at treatment start (baseline), follow-up week 24 (FU24) and follow-up week 96 (FU96). Laboratory data were examined at each date and FIB-4 and APRI were calculated.ResultsLiver elasticity showed a significant decrease from baseline to FU24 (13.1 (3.1–75) kPa to 9.3 (2.9–69.1) kPa; p < 0.0001) and declined further until FU96 (7.9 (2.4–59.3) kPa; p < 0.0001). Liver inflammation and liver function parameters normalised during long-term follow-up. Progression of liver stiffness between FU24 to FU96 de...
