Концентрацию М2-РК в плазме крови определяли твердофазным сэндвич методом иммуноферментного анализа с использованием тест-систем фирмы «ScheBo» (Германия).Результаты. Уровень М2-РК у больных ЯК, БК, СРК и здоровых лиц составил соответственно 29,1±3,0, 17,3±1,5, 7,9±1,6 и 7,0±1,5 ед./мл (р&lt;0,05 – для ЯК и БК в сравнении с СРК и контрольной группой и для ЯК в сравнении с БК). Уровень М2-РК значительно повышался у больных с тяжелой (45,9±6,4 ед./мл) и среднетяжелой (20,9±3,2 ед./мл) формами ЯК, включая пациентов, резистентных к стероидной терапии (61,5±6,2 ед./мл), по сравнению с больными в стадии ремиссии (11,0±1,8 ед./мл, р&lt;0,05) и у пациентов с хроническим непрерывным течением по сравнению с хроническим рецидивирующим течением (40,3±5,0 и 22,7±3,8 ед./мл, р&lt;0,05). Уровень М2-РК имел выраженную тенденцию к повышению с усилением эндоскопической активности ЯК.Увеличение концентрации М2-РК (М±σ контрольной группы, р&lt;0,05) наблюдалось у 76,2% больных ЯК, у 73,3% больных БК и у 15,4% пациентов с СРК.Выводы. Содержание М2-РК в крови больных ЯК и БК значительно возрастает. Повышение уровня М2-РК у больных ЯК ассоциировано с усилением клинико-эндоскопической активности, хроническим непрерывным течением и резистентностью к стероидной терапии.</p></abstract><trans-abstract xml:lang="en"><sec><title>Aim of investigation</title><p>Aim of investigation.

Overall 70 patients were investigated: 42 – with UC, 15 – with CD, 13 – with irritable bowel syndrome (IBS) and 10 healthy patients. Blood plasma concentration of M2-РК was determined by solid-phase sandwich method of enzyme-linked immunoassay with application of «ScheBo» (Germany) test-systems.</p></sec><sec><title>Results</title><p>Results. The level of M2-РК in patients with UC, CD, IBS and healthy persons was 29,1±3,0, 17,3±1,5, 7,9±1,6 and 7,0±1,5 U/ml respectively (р&lt;0,05 – for UC and CD in comparison to IBS and control group and for UC in comparison to CD). The level of M2-РК considerably raised in patients with severe (45,9±6,4 U/ml) and moderate (20,9±3,2 U/ml) UC, including steroid-resistant patients (61,5±6,2 U/ml), in comparison to patients in remission (11,0±1,8 U/ml, р&gt;&lt;0,05) and at patients with chronic continuous course in comparison to chronic relapsing course (40,3±5,0 and 22,7±3,8 U/ml, р&gt;&lt;0,05). The level of M2-РК had the strong tendency to increase with progression of endoscopic activity of UC. Increase of M2-РК concentration (М±σ of the control group, р&gt;&lt;0,05) was observed in 76,2% of UC patients, at 73,3% of patients with CD and in 15,4% of patients with IBS.&gt;&lt; 0,05 – for UC and CD in comparison to IBS and control group and for UC in comparison to CD). The level of M2-РК considerably raised in patients with severe (45,9±6,4 U/ml) and moderate (20,9±3,2 U/ml) UC, including steroid-resistant patients (61,5±6,2 U/ml), in comparison to patients in remission (11,0±1,8 U/ml, р&lt;0,05) and at patients with chronic continuous course in comparison to chronic relapsing course (40,3±5,0 and 22,7±3,8 U/ml, р&gt;&lt;0,05). The level of M2-РК had the strong tendency to increase with progression of endoscopic activity of UC. Increase of M2-РК concentration (М±σ of the control group, р&gt;&lt;0,05) was observed in 76,2% of UC patients, at 73,3% of patients with CD and in 15,4% of patients with IBS.&gt;&lt; 0,05) and at patients with chronic continuous course in comparison to chronic relapsing course (40,3±5,0 and 22,7±3,8 U/ml, р&lt; 0,05).

Blood level of M2-РК of patients with UC and CD increases considerably. Elevation of M2-РК level at patients with UC is associated to enhancement of clinical and endoscopical activity, chronic continuous course and steroid-resistance.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>язвенный колит</kwd><kwd>болезнь Крона</kwd><kwd>М2-пируваткиназа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ulcerative colitis</kwd><kwd>Crohn’s disease</kwd><kwd>М2- pyruvate kinase</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">Михайлова Т.Л., Халиф И.Л.
