Chronic hepatitis B (CHB) and C (CHC) are one of the leading causes of cirrhosis and liver cancer with over a million of people dying annually from their consequences. In Russia CHB and CHC morbidity and related mortality show an upward trend. As a result of recent breakthroughs in antiviral therapeutics CHC became a curable disease. ⋯ However, complete elimination of the virus is possible only using technologies of genome editing, capable of specific cccDNA degradation. Nuclease systems are currently at their early stages of development, and there is a long way to prove their efficacy and safety. Nevertheless, highly promising results of the recent years leave no doubt that CRISPR/Cas systems and similar technologies can become the basis of CHB therapy.
