Монотерапия препаратами с прямым воздействием на вирус менее эффективна по сравнению с их комбинированным применением. Комбинирование агентов с прямым противовирусным действием значительно снижает риск резистентности, увеличивая вероятность эрадикации вируса. Роль рибавирина при различных безинтерфероновых режимах терапии нуждается в уточнении.Заключение. Новые варианты ПВТ, предусматривающие комбинированное применение препаратов с прямым противовирусным действием (без использования интерферона и рибавирина), позволят существенно упростить схемы, сократить сроки и повысить эффективность лечения у всех категорий пациентов. Такие варианты терапии можно считать новой парадигмой лечения ХГС.</p></abstract><trans-abstract xml:lang="en"><sec><title>The aim of review</title><p>The aim of review.

Interferon-free variants of CHC treatment have certain advantages over modes of interferon-α based treatment. Monotherapy by drugs with direct action on virus is less effective in comparison to combined application. Combination of agents with direct antiviral effect considerably reduces risk of resistance, increasing probability of virus eradication. The role of ribavirin at various interferon-free modes of treatment requires specification.</p></sec><sec><title>Conclusion</title><p>Conclusion. New variants of the AVT providing combined application of agents with direct antiviral action (without interferon and ribavirin), will allow to simplify algorithms principally, decrease terms and improve efficacy of treatment in all categories of patients. Such variants of therapy can be considered as a new paradigm of CHC treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический гепатит С</kwd><kwd>противовирусная терапия</kwd><kwd>интерферон-α</kwd><kwd>рибавирин</kwd><kwd>ингибиторы протеазы</kwd><kwd>ингибиторы полимеразы</kwd><kwd>резистентность.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic hepatitis C</kwd><kwd>antiviral therapy</kwd><kwd>interferon α</kwd><kwd>ribavirin</kwd><kwd>protease inhibitors</kwd><kwd>polymerase inhibitors</kwd><kwd>resistance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gilead Sciences I.
