HCV clearance after direct-acting antivirals in patients with cirrhosis by stages of liver impairment: The ITAL-C network study. Issue 9 (September 2017) - Ippolito, Antonio Massimo
Abstract: Background: Sustained virological response (SVR12) rates at 12 weeks after treatment for HCV-infected patients with decompensated cirrhosis are used when referring to those with moderate functional impairment, while few data are available for those with more severe impairment. The use of the cirrhosis staging system proposed by D'Amico might provide new insights on timing for antiviral therapy. Methods: We investigated efficacy (SVR12), safety, and post-treatment variations in clinical and laboratory parameters in 2612 patients with advanced fibrosis (n = 575) or cirrhosis (n = 2037). Cirrhosis was in the compensated phase (without/with varices) or had previously been in the decompensated stage. Different direct-acting antiviral (DAA) regimens were administered in accordance with scientific guidelines. Results: The SVR12 rate was 97.6% in patients with advanced fibrosis. For patients with cirrhosis, the rate was 96.5% in stage 1, 95.1% in stage 2, 100% in stage 3, 95.7% in stage 4, and 93.6% in stage 5. These rates were independent of gender, age, HCV genotype, and treatment schedule. Positive changes in biochemical parameters and CPT classes following therapy were evident in compensated and previously decompensated patients. Conclusion: Our findings support the use of DAAs in patients with advanced cirrhosis (stages 3–5) who are at greatest risk and have the most to gain from therapy.
