HDV — гепатотропный, дефектный РНК-вирус, который требует для своей репликации и формирования инфекционных частиц обязательного присутствия HBV. Около 10% больных хроническим HBsAg-позитивным гепатитом инфицированы HDV. HDV вызывает развитие гепатита в виде ко-инфекции (одновременное заражения HBV и HDV) и суперинфекции (инфицирование HDV на фоне хронического гепатита В). Естественное течение данной инфекции характеризуется быстрым прогрессированием заболевания до ЦП и ГЦК. Диагностика HDV-инфекции основывается на выявлении дельта-антигена, антител к вирусу (anti-HDV IgM и IgG) и RNA HDV в сыворотке крови. Эффективность противовирусной терапии доказана только на фоне лечения препаратами интерферона (ИФН-2α и ПЭГ-ИФН-2α). Единственным методом защиты от инфицирования HDV является вакцинопрофилактика против ГВ.</p></abstract><trans-abstract xml:lang="en"><p>A significant part of liver disease, once considered the result of infection by hepatitis B virus (HBV), are the result of infection HBV, and hepatitis delta virus (HDV). HDV is hepatotropic, defective RNA virus that requires obligatory HBV presence for its replication and the formation of infectious particles. About 10% of patients with chronic HBsAg-positive hepatitis infected by HDV. HDV results in coinfection (simultaneous infection of HBV and HDV) and superinfection (HDV infection with chronic hepatitis B). The natural course of the infection is characterized by rapid progression to liver cirrhosis and hepatocellular carcinoma. Diagnosis of HDV-infection is based on the detection of delta antigen, antibodies to the virus (anti-HDV IgM and IgG) and RNA HDV in serum. The effectiveness of antiviral therapy proved only on the treatment by interferon (IFN-2α and PEG-IFN-2α). The only way to protect against HDV infection is vaccination against hepatitis B.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гепатит дельта</kwd><kwd>ко-инфекция</kwd><kwd>суперинфекция</kwd><kwd>цирроз печени</kwd><kwd>гепатоцеллюлярная карцинома</kwd><kwd>противовирусная терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatitis delta</kwd><kwd>coinfection</kwd><kwd>superinfection</kwd><kwd>liver cirrhosis</kwd><kwd>hepatocellular carcinoma</kwd><kwd>antiviral therapy</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">Абдурахманов Д.Т.
