Лечение ХГВ до сих пор затруднено из-за отсутствия препаратов, полностью элиминирующих вирус гепатита В (HBV) из гепатоцита. Целью работы было описать клинико-лабораторные особенности ХГВ, оценить эффективность противовирусной терапии и выявить факторы, ассоциированные с ответом на нее. На основании первичной документации проведена оценка результатов клинико-лабораторного и инструментального обследования, а также данных серологических и молекулярно-биологических методов исследований пациентов (n = 201), наблюдавшихся в период 2007–2021 гг. в Центре диагностики и лечения хронических вирусных гепатитов КБ № 85 ФМБА России. Большинство пациентов в группе — мужчины (56,7%); преобладали HBeAg-негативные больные (93%). У девяти (4,5%) пациентов диагностирован ЦП, у одного из них — ГЦК. Генотип D HBV установлен в 95,4% случаев, А — в 3,1% и С — в 1,5%. После года терапии аналогами нуклеоз(т)идов (энтекавир или тенофовир) у 88% пациентов отсутствовала виремия, нормализовались биохимические показатели (88%). Общий уровень сероконверсии по HBeAg составил 41,7% и по HBsAg — 3%. Таким образом, получены высокая частота достижения вирусологического ответа и нормализация активности ферментов. Низкий исходный уровень виремии является независимым прогностическим фактором для достижения вирусологического ответа. Уровень HBsAg в конце терапии позволяет прогнозировать рецидив после окончания лечения.</p></abstract><trans-abstract xml:lang="en"><p>Chronic hepatitis B (CHB) is a common infectious disease that represents one of the main causes of liver cirrhosis (LC) and hepatocellular carcinoma (HCC). CHB is still difficult to treat due to the lack of drugs that completely eliminate hepatitis B virus (HBV) from hepatocytes. The study was aimed to describe the CHB clinical and laboratory features, assess the efficiency of antiviral therapy and identify the factors associated with the response to antiviral therapy. The results of clinical and laboratory assessment, instrumental examination, serological and molecular testing of the patients (n = 201) followed up between 2007–2021 in the Viral Hepatitis Diagnosis and Treatment Center at the Clinical Hospital No. 85 of FMBA of Russia were assessed based on primary sources. Most of the patients in the group were males (56.7%); the HBeAg-negative patients predominated (93%). LC was diagnosed in nine patients (4.5%), among them one patient had HCC. The HBV D genotype was determined in 95.4% of cases, А genotype in 3.1% of cases, and С genotype in 1.5% of cases. After a year of treatment with the nucleos(t)ide analogues (entecavir or tenofovir) 88% of patients showed no viremia and their biochemical parameters were back to normal (88%). The overall seroconversion rate was 41.7% for HBeAg and 3% for HBsAg. Thus, high rates of virological response and enzyme activity normalization were obtained. Low baseline viremia level is an independent prognostic factor of achieving a virological response. The HBsAg level in the end of therapy makes it possible to predict relapse after the treatment cessation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический гепатит В</kwd><kwd>противовирусная терапия</kwd><kwd>прогностические факторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic hepatitis B</kwd><kwd>antiviral therapy</kwd><kwd>prognostic factors</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">World Health Organization.
