Применение препаратов прямого противовирусного действия (ПППД) приводит к достижению устойчивого вирусологического ответа (УВО) у 95–100 % больных с HCV-ассоциированным криоглобулинемическим васкулитом (HCV-КВ). Однако у некоторых больных, несмотря на эрадикацию вируса, сохраняются клинические и иммунологические маркеры васкулита.</p></sec><sec><title>Цель</title><p>Цель. Оценить клинический и иммунологический ответы у больных с HCV-КВ в сопоставлении с больными «бессимптомной» HCV-ассоциированной криоглобулинемией (HCV-КГ) после достижения УВО с помощью ПППД при длительном динамическом наблюдении (12 мес).</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. В исследование включены 45 больных: 23 с HCV-КВ и 22 с HCV-КГ, которым проводили противовирусную терапию ПППД. Клинико-иммунологические, вирусологические данные были оценены: до лечения, через 12 нед (3 мес) и 48 нед (12 мес) после окончания лечения.</p></sec><sec><title>Результаты</title><p>Результаты. После проведенного курса ПППД УВО был констатирован у всех 45 (100 % больных). У больных с HCV-КВ иммунологический ответ (полный и частичный) наблюдали к 12-й неделе (УВО12) – у 56,5 % и к 48-й неделе (УВО48) – у 73,9 %. У 6 больных (26,1 %) иммунологический ответ не был достигнут к УВО48. Частота полного и частичного клинического ответа через 12 нед после окончания лечения на сроке УВО12 у больных с HCV-КВ составила 65,2 %, к сроку УВО48 составило 78,3 %. У 5 (21,7 %) – отдельные проявления криоглобулинемического васкулита (КВ) сохранялись и/или рецидивировали. У больных с HCV-КГ частота полного и частичного иммунологического ответа после терапии ПППД составила к сроку УВО12 77,3 % и на сроке УВО48 – 86,3 %. Отсутствие ответа наблюдалось у 3 больных и характеризовалось криоглобулинемией следового уровня.</p></sec><sec><title>Заключение</title><p>Заключение. У большинства больных с HCV-КВ эрадикация HCV с помощью ПППД приводит к достижению клинико-иммунологической ремиссии заболевания. Однако у 20 % больных сохраняются/рецидивируют проявления КВ сразу после окончания лечения или наблюдаются более поздние рецидивы. Основываясь на этих наблюдениях, больным с HCV-КВ, особенно с исходным тяжелым поражением кожи, почек, требуется долгосрочный мониторинг после достижения УВО.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The use of direct acting antiviral drugs (DAАs) leads to the achievement of a stable virological response (SVR) in 95–100 % of patients with HCV-associated cryoglobulinemic vasculitis (HCV-CV). However, in some patients, despite the eradication of the virus, clinical and immunological markers of vasculitis still remain.</p></sec><sec><title>The aim</title><p>The aim: to evaluate clinical and immunological responses in patients with HCV-CV in comparison with patients with "asymptomatic" HCV- associated cryoglobulinemia (HCV- СG) after achieving SVR with the help of DAАs with long-term dynamic observation (12 months).</p></sec><sec><title>Patients and Methods</title><p>Patients and Methods: The study included 45 patients: 23 with HCV-CV and 22 with "asymptomatic" HCV-CG, who underwent antiviral therapy with DAAs. Clinical-immunological, virological data were evaluated: before treatment, 12 weeks (3 months) and 48 weeks (12 months) after the end of treatment.</p></sec><sec><title>Results</title><p>Results: After a course of DAAs, SVR was diagnosed in all 45 (100 % of patients). In patients with HCV-CV, an immunological response (complete and partial) was observed by week 12 (SVR12) – in 56.5 % and by week 48 (SVR48) – in 73.9 % patients. In 6 patients (26.1 %), the immunological response was not achieved by SVR48. The rate of complete and partial clinical response 12 weeks after the end of treatment at the SVR12 period in patients with HCV-CV was 65.2 %, to the time of SVR48 amounted to 78.3 % patients. In 5 (21.7 %) individual manifestations of CV persisted and/or relapsed. In patients with HCV-CG, the frequency of complete and partial immunological responses after DAAs therapy was 77.3 % – by SVR12 and 86.3 % – by SVR48, respectively. No response was observed in 3 patients and it was characterized by trace-level of cryoglobulinemia.</p></sec><sec><title>Conclusion</title><p>Conclusion: In most patients with HCV-CV eradication of HCV with help of DAAs leads to the achievement of clinical and immunological remission of the disease. However, in 20 % of patients manifestations of HCV-CV persist / recur immediately after the end of treatment or later relapses are observed. Based on these observations, patients with HCV-CV, especially those with severe underlying skin and kidney disease, are required long-term monitoring after SVR is achieved.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>криоглобулинемический васкулит</kwd><kwd>HCV-инфекция</kwd><kwd>препараты прямого противовирусного действия</kwd><kwd>иммунологический ответ</kwd><kwd>клинический ответ</kwd><kwd>устойчивый вирусологический ответ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cryoglobulinemic vasculitis</kwd><kwd>HCV infection</kwd><kwd>direct antiviral drugs</kwd><kwd>immunological response</kwd><kwd>clinical response</kwd><kwd>sustained virological response (SVR)</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">Bonacci M., Lens S., Mariño Z. et al.
