Противовирусная терапия аналогами нуклеоз(т)идов хронического гепатита В направлена на предотвращение прогрессирования заболевания и развития осложнений. Однако существующая терапия не позволяет ликвидировать вирус гепатита В, и для сохранения клинического эффекта у большинства пациентов требуется длительное лечение. В связи с этим изучение факторов, ассоциированных с эффективностью аналогов нуклеоз(т)идов, является актуальным.Цель - оценка эффективности и выявление предикторов ответа на противовирусную терапию аналогами нуклеоз(т)идов у пациентов с хроническим гепатитом В.Материалы и методы. Ретроспективно-проспективное обсервационное исследование включало 71 пациента с хроническим гепатитом В, получавших аналоги нуклеоз(т)идов в Центре диагностики и лечения хронических вирусных гепатитов в период с 2008 г. по 2023 г. Эффективность терапии аналогами нуклеоз(т)идов оценивалась через 24, 48 и 96 недель приема препаратов. Были изучены прогностические факторы, ассоциированные с получением вирусологического ответа через год противовирусной терапии и с достижением выраженного снижения плотности печени при транзиентной эластометрии.Результаты. Частота вирусологического и биохимического ответа увеличивалась по мере продолжения противовирусной терапии, а через 96 недель приема аналогов нуклеоз(т)идов составила 92,6 %. Исходный уровень вирусной нагрузки представляет собой независимый прогностический фактор достижения авиремии через 48 недель терапии (p=0,022). Клиренс HBsAg наблюдался у 2 (2,8 %) пациентов, клиренс HBeAg — у 5 HBeAg-позитивных пациентов. На фоне приема аналогов нуклеоз(т)идов было отмечено значимое снижение фиброза печени по данным транзиентной эластометрии, при этом ее высокий уровень в начале противовирусной терапии является фактором, связанным с выраженным снижением плотности печени (на 25 % и более) (p=0,022).Заключение. Противовирусная терапия аналогами нуклеоз(т)идов продемонстрировала высокую эффективность при подавлении репликации вируса гепатита В, нормализации активности аминотрансфераз и уменьшении фиброза печени. Исходные уровни вирусной нагрузки и транзиентной эластометрии являются наиболее важными прогностическими факторами, ассоциированными с эффективностью противовирусной терапии аналогами нуклеоз(т)идов.</p></abstract><trans-abstract xml:lang="en"><p>Background: Antiviral therapy with nucleos(t)ide analogs for chronic hepatitis B is aimed at preventing disease progression and the development of complications. However, current therapies do not allow elimination of hepatitis B virus, and long-term treatment is required to maintain clinical effect in most patients. In this regard, the study of associated factors with the efficacy of antiviral therapy of nucleos(t)ide analogs is actual.Aim: To evaluate efficacy and identify predictors of response to antiviral therapy with nucleos(t)ide analogs in patients with chronic hepatitis B.Materials and methods: This retrospective-prospective observational study included 71 patients with chronic hepatitis B who received nucleos(t)ide analogs at the Center for Diagnosis and Treatment of Chronic Viral Hepatitis from 2008 to 2023. The efficacy of antiviral therapy with nucleos(t)ide analogs was evaluated after 24, 48, and 96 weeks of drug intake. The prognostic factors associated with obtaining a virologic response after one year of antiviral therapy and with achieving a significant decrease in liver density by transient elastometry were examined. Results: The virologic and biochemical response rate increased as antiviral therapy continued, and after 96 weeks of taking nucleos(t)ide analogs was 92.6 %. Baseline viral load level was an independent prognostic factor for achieving aviremia after 48 weeks of antiviral therapy (p=0.022). HBsAg clearance was observed in 2 (2.8 %) patients, HBeAg clearance — in 5 HBeAg-positive patients. On nucleos(t)ide analogs treatment there was a significant decrease of liver fibrosis measured by transient elastometry, and a high level of transient elastometry at the beginning of antiviral therapy is a factor associated with a significant decrease in liver density (by 25 % or more) (p=0.022).Conclusion: Antiviral therapy with nucleos(t)ide analogs has demonstrated high efficacy in suppressing hepatitis B virus replication, normalizing aminotransferase activity, and reducing liver fibrosis. Baseline viral load and transient elastometry levels are the most important prognostic factors associated with the efficacy of antiviral therapy with nucleos(t)ide analogs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>противовирусная терапия</kwd><kwd>аналоги нуклеоз(т)идов</kwd><kwd>эффективность</kwd><kwd>фиброз печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Antiviral therapy</kwd><kwd>nucleoside and nucleotide analogs</kwd><kwd>efficacy</kwd><kwd>liver fibrosis</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.
