Blood serum was analyzed for the presence of antibodies to HBcAg (anti-HBc) by semi-quantitative method and the content of antibodies to HBsAg by quantitative method. Patients were included in the study consecutively, the inclusion criterion was negative HBsAg test, the exclusion criteria were co-infection with hepatitis C virus or HIV.</p> <p><bold>Results.</bold> It was found that 64 (14%) patients were anti-HBs positive, in this group more than half [39 (61%)] had no antibodies to HBsAg (anti-HBs) in protective titer (more than 10 IU/mL), and 26 patients had no anti-HBs at all. Overall, only 130 (30%) patients in the cohort had anti-HBs in protective titer. Retrospective analysis of case histories and outpatient records revealed 33 cases of transaminase elevation, and in 15 patients this adverse event was the cause of antirheumatic drug withdrawal. Clinically significant thrombocytopenia occurred in 10 patients.</p> <p><bold>Conclusion. </bold>Extended HBV screening for RA patients showed the absence of anti-HBV protection in 70% of patients. Latent HBV [HBsAg(-)/anti-HBc(+)] was detected in 14% of patients. It is necessary to be alert to cases of combined elevation of ALT and/or AST and thrombocytopenia as symptoms of probable exacerbation of HBV infection.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Провести серологический скрининг на наличие признаков перенесенной HBV-инфекции среди больных ревматоидным артритом (РА), определить уровень защитных антител к HBV среди взрослых пациентов стационарных отделений ФГБНУ «НИИ ревматологии им. В.А. Насоновой», в ходе ретроспективного анализа изучить клинико-лабораторные особенности больных РА со скрытым гепатитом В.</p> <p><bold>Материалы и методы. </bold>В исследование включены 440 HBsAg-негативных больных РА старше 18 лет. Проводился анализ сыворотки крови на наличие антител к HBcAg (анти-НВс) полуколичественным методом и содержание антител к HBsAg количественным методом. Пациентов включали в исследование последовательно, критерием включения служил отрицательный тест на HBsAg, критерием исключения – коинфекция вирусом гепатита С или ВИЧ.</p> <p><bold>Результаты. </bold>Обнаружено, что 64 (14%) пациента были позитивными по анти-НВс, в этой группе более 1/2 [39 (61%)] не имели антител к HBsAg (анти-HBs) в защитном титре (&gt;10 мМЕ/мл), а у 26 больных анти-HBs отсутствовали. В целом в исследованной когорте анти-HBs в защитном титре присутствовали всего у 130 (30%) больных. Ретроспективный анализ историй болезни и амбулаторных карт выявил 33 случая повышения трансаминаз, при этом у 15 пациентов это нежелательное явление стало причиной отмены антиревматического препарата. У 10 больных выявлена клинически значимая тромбоцитопения.</p> <p><bold>Заключение.</bold> Расширенный скрининг на HBV для больных РА показал отсутствие противоинфекционной защиты у 70% больных. Скрытая форма HBV [(HBsAg(-)/anti-HBc(+)] обнаружена у 14% больных. Необходимо проявлять настороженность в отношении случаев сочетанного повышения аланинаминотрансферазы (АЛТ) и/или аспартатаминотрансферазы (АСТ) и тромбоцитопении как симптомов вероятного обострения HBV-инфекции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>immunosuppressive therapy</kwd><kwd>antirheumatic drugs</kwd><kwd>chronic viral hepatitis B</kwd><kwd>HBsAg</kwd><kwd>anti-HBc</kwd><kwd>screening</kwd><kwd>reactivation</kwd><kwd>prevention</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>иммуносупрессивная терапия</kwd><kwd>антиревматические препараты</kwd><kwd>хронический вирусный гепатит В</kwd><kwd>HBsAg</kwd><kwd>анти-HBc</kwd><kwd>скрининг</kwd><kwd>реактивация</kwd><kwd>профилактика</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The article was conducted as part of the scientific research work of the Nasonova Research Institute of Rheumatology.
