title: Management of HCV in cirrhosis-a rapidly evolving landscape.
abstract: Despite the rapid progress in treatment, chronic hepatitis C virus (HCV) infection remains a growing cause of liver-related mortality globally. Patients who have been infected for decades are now presenting with advanced liver disease with the complications of cirrhosis and liver cancer. Early attempts at treatment with peginterferon and ribavirin were limited by toxicity, long treatment duration, and limited efficacy. This was especially relevant for patients with cirrhosis, where exposure to peginterferon-based therapy was relatively ineffective and led to high rates of toxicity. However, the recent development of multiple novel direct-acting antivirals (DAAs) has revolutionized the treatment of HCV. The majority of patients can now be cured with short courses of extremely well-tolerated all-oral regimens. However, the real test of these regimens comes in patients with more advanced liver disease, both in terms of safety and efficacy. Patients with cirrhosis have the greatest need for therapy and have traditionally been the most difficult to cure. The new therapies are rapidly changing this paradigm. Accumulating data suggest that high cure rates are achievable in patients with compensated cirrhosis and may even be possible in patients with signs of liver failure. This review will focus on the treatment of HCV in patients with cirrhosis, with an emphasis on the challenges that remain and strategies to deal with this important population.
