Снижение концентрации АЦЦП или их сероконверсия отмечены не для всех групп противовоспалительных препаратов. Серопозитивность по АЦЦП является предиктором более высокой эффективности абатацепта (АБЦ). Возможность сероконверсии АЦЦП, как и ревматоидного фактора (РФ), при терапии АБЦ сопряжена с более выраженным подавлением клинических симптомов активности РА и прогрессирования деструкции суставов, достижением ремиссии у большой части пациентов.</p></abstract><trans-abstract xml:lang="en"><p>The detection of anti-cyclic citrullinated peptide (anti-CCP) antibodies plays a diagnostic and statistical predictive role in rheumatoid arthritis (RA). The decreased concentration of anti-CCP antibodies or their seroconversion is observed for not all groups of anti-inflammatory drugs. Seropositivity for anti-CCP antibodies is a predictor of the higher efficacy of abatacept (ABC). The possibility of seroconversion of anti-CCP antibodies, like rheumatoid factor, during treatment with ABC is associated with the more pronounced suppression of clinical symptoms of RA activity and progressive joint destruction, with remission achievement in a large proportion of patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>серопозитивность</kwd><kwd>сероконверсия</kwd><kwd>антитела к циклическому цитруллинированному пептиду</kwd><kwd>ревматоидный артрит</kwd><kwd>ревматоидный фактор</kwd><kwd>абатацепт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>seropositivity</kwd><kwd>seroconversion</kwd><kwd>anti-cyclic citrullinated peptide antibodies</kwd><kwd>rheumatoid arthritis</kwd><kwd>rheumatoid factor</kwd><kwd>abatacept.</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">Smolen JS, Aletaha D, Bijlsma JW, et al.
