The secondary inefficiency of ACT has been found to depend on the level of antibodies to IFX (anti-IFX Ab). The Department of Intestinal Pathology, Central Research Institute of Gastroenterology, is investigating the mechanisms for the occurrence of primary and secondary inefficiency of ACT, as well as ways to overcome them by cultured allogenic bone marrow mesenchymal stromal cells (MSC). In the framework of the searching investigation evaluating the efficiency and safety of MSC in patients with IBD, the investigators revealed that was a phenomenon of a decrease in anti-IFX Ab and came to the conclusion that the secondary inefficiency of ACT should be overcome in a patient with ulcerative colitis (UC). The elevated anti-IFX Ab levels were directly associated with the worsening clinical and endoscopic picture of UC and with the enhanced activity of an inflammatory process. The administration of cultures MSC contributed to lower anti-IFX Ab levels, overcome secondary inefficiency (an escape phenomenon) during ACT, and enhanced IFX sensitivity. The clinical observation indicated that MSC administration reduced anti-IFX concentrations and promoted UC remission during IFX therapy. Thus, MSC transplantation can be considered as a promising method for overcoming the secondary inefficiency of ACT, which aids in increasing the previously lost response to anti-inflammatory therapy.</p></abstract><trans-abstract xml:lang="ru"><p>Аннотация. Поиск путей преодоления вторичной неэффективности антицитокиновой терапии (АЦТ) инфликсимабом (ИНФ) у больных с воспалительными заболеваниями кишечника (ВЗК) остается актуальным и обусловливает необходимость новых подходов к решению данной проблемы. Установлено, что вторичная неэффективность АЦТ зависит от уровня антител к инфликсимабу (АТИ). В отделе патологии кишечника ЦНИИГ проводится изучение механизмов возникновения первичной и вторичной неэффективности АЦТ, а также пути их преодоления с помощью культуры аллогенных мезенхимальных стромальных клеток (МСК) костного мозга. В рамках поисковой работы, оценивающей эффективность и безопасность МСК у больных с ВЗК, нами выявлен феномен снижения уровня АТИ и как следствие преодоление вторичной неэффективности АЦТ у больного язвенным колитом (ЯК). Повышение уровня АТИ напрямую связано с ухудшением клинической и эндоскопической картины ЯК, повышением активности воспалительного процесса. Введение культуры МСК способствовало снижению уровня АТИ, преодолению вторичной неэффективности (феномена "ускользания") при проведении АЦТ, и повышению чувствительности к ИНФ. Клиническое наблюдение показало, что введение МСК снижает уровень АТИ и способствует наступлению ремиссии ЯК на фоне терапии ИНФ. Поэтому введение культуры МСК можно рассматривать в качестве перспективного метода преодоления вторичной неэффективности АЦТ, способствующего повышению утраченной ранее чувствительности к противовоспалительной терапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>inflammatory bowel diseases</kwd><kwd>immunogenicity</kwd><kwd>infliximab</kwd><kwd>mesenchymal stromal cell</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника</kwd><kwd>иммуногенность</kwd><kwd>инфликсимаб</kwd><kwd>мезенхимальные стромальные клетки</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ben-Horin S., Chowers Y.
