Detailed Description

Presence of anti-E1E2 antibodies was previously associated with spontaneous cure of hepatitis C virus (HCV). The hypothesis was to check whether baseline anti-E1E2 antibodies could predict virological outcome in HCV-infected patients receiving direct-acting antiviral treatment

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of patients with positive anti-E1E2 antibody level at treatment initiation
Time Frame: Baseline (treatment initiation day)
Anti-E1E2 antibody levels were determined using optical densities obtained after dilution of patients' serum samples at 1/250 and 1/500. Samples with anti-E1E2 levels above 950 (OD value× 1000) were considered positive
Baseline (treatment initiation day)
