Effect of sofosbuvir plus daclatasvir on virological response and liver function tests as a line of treatment for HCV related cirrhosis (a prospective cohort study)

Abstract

BackgroundPatients with chronic HCV infection are the most in need for antiviral treatment. However, patients with cirrhosis exhibit difficulty with direct antiviral agents (DAA) treatment. We intended to evaluate the virological response of DAA in HCV-related cirrhosis treatment as well as its effect on liver function tests and other laboratory tests. Our study was a prospective cohort study of 240 patients with HCV-related liver cirrhosis. Those patients were consecutively selected from Gastroenterology and Hepatology out-patient clinic at Aswan University Hospital. They were subjected to the DAA regimen (sofosbuvir 400 mg plus daclatasvir 60 mg).ResultsThe study showed a rapid decrease in HCV viral load; HCV RNA was undetectable in 65% of patients on 4th week of treatment and in 88.3% of patients on 8th week of treatment. It was undetectable in 100% of patients on 12th week of treatment and remained unchanged until therapy was completed (24 weeks). The SVR (sustained virological response) was 96.3%. Other laboratory tests demonstrated that serum level of alanine aminotransferase (ALT) decreased rapidly to normal limits on 4th week of treatment and remained within normal range until 12th week post-treatment. Significant improvements in serum albumin, total bilirubin, INR, and alpha-fetoprotein (AFP) levels were observed during and after treatment. Child-Pugh score showed a significant improvement post-treatment. We also observed a significant improvement in platelet count during and after treatment.ConclusionThe DAA regimen (sofosbuvir 400 mg plus daclatasvir 60 mg) for treatment of HCV-related liver cirrhosis can achieve satisfactory virological response (SVR more than 96%). It can lead to improvement of serum ALT, serum albumin, total bilirubin, INR, AFP, and Child-Pugh score and also increase in platelet count after treatment.
