Long-Term Follow-Up of Advanced Liver Disease after Sustained Virological Response to Treatment of Hepatitis C with Direct-Acting Antivirals: Outcomes from a Real-World Portuguese Cohort.

ABSTRACT:

Background

Direct-acting antivirals (DAA) have revolutionized hepatitis C treatment, with high sustained virological response (SVR) rates reported, even in historically difficult-to-treat groups. SVR is associated with a decreased risk of hepatocellular carcinoma (HCC), need for transplantation, and overall and liver-related mortality. Data from real-life cohorts on the medium- to long-term outcomes of patients with advanced liver disease and DAA-induced SVR are still missing.

Objectives

To report and analyze the long-term outcomes of DAA-induced SVR in a real-life cohort of patients with advanced liver disease.

Method

In this retrospective, longitudinal, single-center study, we collected data from patients with chronic hepatitis C infection and advanced liver disease (cirrhosis or advanced fibrosis) that had initiated DAA treatment between February 2015 and January 2017.

Results

A total of 237 patients were included. A treatment completion rate of 98.7% and an SVR rate of 97.8% (intention to treat: 96.6%) were found. Of the 229 patients with SVR, 67.2% were cirrhotic (64.2% Child-Pugh class A; 3.1% Child-Pugh class B) and 32.8% had stage F3 fibrosis, with an average follow-up of 28 months. The overall mortality rate was 19/1,000 person-years and the liver-related mortality rate was 9.5/1,000 person-years. The hepatic decompensation incidence rate was 25/1,000 person-years and the HCC incidence rate was 11.6/1,000 person-years. There was a sustained increase in serum platelet values during up to 2 years of follow-up. A history of pretreatment decompensation and baseline platelet and albumin values were significantly associated with the occurrence of adverse liver events after the end of treatment.

Conclusions

A DAA-induced SVR remains durable and is associated with an excellent clinical prognosis in patients with compensated advanced liver disease and with improvement or disease stabilization in decompensated patients. SVR is associated with a low risk of - yet does not prevent - HCC occurrence or disease progression, especially in the presence of other causes of liver injury. It is recommended that these patients be kept under surveillance.

Project description:High hepatitis C cure rates have been observed in registration trials with second-generation direct-acting antivirals. Real-world data also indicate high sustained viral response (SVR) rates. Our objective was to determine real-world SVR rates for patients infected with hepatitis C virus (HCV) who were treated with second-generation direct-acting antivirals in the first 18 months of their availability in Canada.Four centres in Calgary contributed their treatment data for a diverse patient population including those who had or had not undergone liver transplantation, those coinfected with HIV and vulnerable populations. We included all patients documented to have started hepatitis C treatment with direct-acting antivirals between October 2014 and April 2016, with follow-up through October 2016. We used multivariate analysis to determine independent predictors of treatment failure.Outcome data were available for 351 patients, of whom 326 (92.9%) achieved an SVR (193/206 [93.7%], 57/59 [96.6%] and 44/51 [86.3%] for genotypes 1a, 1b and 3, respectively, p = 0.2). Independent predictors of not achieving SVR were older age (adjusted odds ratio [OR] 0.95 [95% confidence interval (CI) 0.90-1.00]), male sex (adjusted OR 0.30 [95% CI 0.10-0.89]) and, in patients with genotype 1a infection, history of hepatocellular carcinoma (adjusted OR 0.13 [95% CI 0.03-0.53]). In the entire cohort, the presence of cirrhosis, genotype and hepatocellular carcinoma were not associated with a lower SVR rate. There were no differences in SVR rate according to treatment centre, HIV coinfection or liver transplantation. Among patients with genotype 3 infection, a significantly lower SVR rate was observed for those treated outside of standard of care than for those treated within standard of care (33.3% v. 89.6%, p = 0.04). De novo hepatocellular carcinoma developed in 12 patients (3.4%) despite successful direct-acting antiviral therapy.We report high SVR rates in a real-world diverse cohort of HCV-infected patients treated with second-generation direct-acting antivirals. The results highlight the importance of conducting real-world analyses to elucidate clinical factors associated with poorer outcomes that may not be identified in registration trials.
