Разработать тест-систему для определения аутоантител против  β1 -адренорецептора (анти-β1-АР). Изучить влияние удаления аутоантител на сократительную функцию миокарда левого желудочка (ЛЖ). Материал и методы. Пептиды, соответствующие фрагментам второй внеклеточной петли β1-АР человека (197-222 а.о.) были синтезированы модифицированным твердофазным методом и лиофилизованы. Контроль молекулярной массы осуществляли с помощью лазерно-десорбционной масс-спектрометрии. Были обследованы 47 больных с целью выявления анти- β1-АР. Из них с диагнозом дилатационная кардиомиопатия (ДКМП) – 22, ишемическая кардиомиопатия – 8, постинфарктный кардиосклероз – 6, миокардит – 3, алкогольная кардиомиопатия – 1, посттрансплантационная кардиомиопатия – 7. Удаление анти- β1-АР проводили 4 больным с ДКМП: 3 – методом плазмафереза (ПФ) и 1 пациенту – методом иммуноадсорбции (ИА). Результаты. Разработана иммуноферментная тест-система для определения аутоантител с использованием в качестве антигена пептида, содержащего 26 аминокислот второй внеклеточной петли β1-АР. Показано, что удаление анти-β1-АР у больных ДКМП методами ИА и ПФ приводит к улучшению сократительной функции миокарда ЛЖ. Заключение. Важно выяснить, объясним ли факт улучшения сократительной функции миокарда только удалением анти- β1-АР. Следует разработать более совершенные методы детекции анти- β1-АР, других аутоантител к миокарду, установить их роль в нарушении сократительной функции миокарда.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To develop a test system measuring β1-adrenoreceptor antibody (anti- β1-AR) level. To study the effects of autoantibody removal on left ventricular (LV) contractility. Material and methods. Peptides, according to second human extracellular β1-AR loop fragments (197-222 amino acid fragments), were synthesized by modified hard-phase method and then lyophilized. Molecular mass control was performed by laser desorption mass spectrometry. In total, 47 patients were examined, with the aim of anti- β1-AR detection. Dilated cardiomyopathy (DCMP) was diagnosed in 22 patients, ischemic CMP – in 8, post-infarction cardiosclerosis – in 6, myocarditis – in 3, alcohol CMP – in 1, and post-transplantation CMP – in 7 participants. Anti- β1-AR were removed in 4 DCMP patients, by plasmapheresis (PF; n=3) or immunoadsorption (IA; n=1).  Results. A new immune-enzyme test system for autoantibody detection has been developed, using the second extracellular β1-AR loop 26 amino acid peptide as the antigen. Anti- β1-AR removal by IA or PF methods resulted in improved LV contractility among DCMP patients. Conclusion. It is important to determine whether LV contractility improvement is explained by anti-β1-AR removal exclusively. More advanced methods for anti- β1-AR and other anti-myocardial antibody detection should be developed, and auto-antibodies’ role in impaired myocardial contractility should be studied.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аутоантитела против β1-адренорецептора</kwd><kwd>иммуноадсорбция</kwd><kwd>плазмаферез</kwd><kwd>сократимость миокарда левого желудочка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>β1-adrenoreceptpor auto-antibodies</kwd><kwd>immuno-adsorption</kwd><kwd>plasmapheresis</kwd><kwd>left ventricular myocardial contractility</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">Grogan M, Redfoeld MM, Bailey KR, et al.
