Efficacy and Safety of Sofosbuvir-Based Direct Acting Antivirals for Hepatitis C in Septuagenarians and Octogenarians
Abstract
Background/aims: Treatment of chronic hepatitis C (HCV) with newer direct acting antiviral (DAA) agents has been highly effective. Unfortunately, patients over 70 years old are underrepresented in studies. Given current recommendations to screen patients born between 1945 and 1965 for HCV, it is essential to determine the efficacy and safety of DAAs within the elderly population. This study aims to evaluate clinical outcomes of patients aged 70 years or older treated for HCV with DAAs at a single tertiary care center.
Methods: We identified 25 patients aged 70 years or older who were treated for HCV with a sofosbuvir-based regimen. Baseline demographics, prior HCV treatment history, HCV treatment regimen, adverse effects, and interruption or discontinuation of therapy were collected. The primary endpoint was sustained virologic response at 12 weeks after end of treatment (SVR12). Secondary outcomes were self-reported side effects, drug interactions, and changes in medical regimen of treated patients.
Results: All patients were genotype 1 (13 1a, 9 1b, 3 unspecified). Seventeen (68%) had cirrhosis including 1 Child's Pugh class B. Fifteen patients were treatment-naïve and 10 previously failed treatment with interferon. Seventeen patients were on ledipasvir/sofosbuvir, 4 on simeprevir/sofosbuvir/ribavirin, and 4 on simeprevir/sofosbuvir. Of 25 patients included, 96% (24/25) patients achieved SVR12. Two patients had a greater than 2 g/dL drop in hemoglobin from baseline and…
