Обследовано 109 пациентов (37,7±11,7 года) с ВЗК (50 человек–с язвенным колитом, 41-с болезнью Крона, 18 пациентов с неклассифицированным колитом), из них 36 пациентов обследованы в динамике в течение 0,5–1 года, и 53 обследуемых группы сравнения. С учетом наблюдения в динамике в 109 случаях установлено наличие обострения ВЗК и в 36 случаях — ремиссия заболеваний. Электрические и вязкоупругие параметры эритроцитов исследованы методом диэлектрофореза. Уровень фекального кальпротектина определен методом ИФА (R-Biopharm, Германия).</p></sec><sec><title>Результаты</title><p>Результаты. Установлены дифференцирующие значения для ряда параметров эритроцитов: среднего диаметра клетки, поляризуемости на частоте 106 Гц, скорости поступательного движения к электродам, амплитуды деформации на частоте 106 Гц, обобщенных показателей вязкости, жесткости, электропроводности, положения равновесной частоты и уровня фекального кальпротектина для различения пациентов с ВЗК в стадии обострения и ремиссии. Предложенный способ комбинированного использования параметров эритроцитов и уровня фекального кальпротектина обеспечил достаточную диагностическую точность: чувствительность 91,9%, специфичность — 93,1%, индекс точности 92,3%. Преимуществами данного подхода являются малоинвазивность, высокая производительность, независимость определения от квалификации и опыта специалиста, малая затратность и трудоемкость, приемлемость для пациента. Данный подход позволяет установить наличие обострения или ремиссии независимо от нозологической формы ВЗК.</p></sec><sec><title>Заключение</title><p>Заключение.

We examined 109 patients (37.7±11.7 years) with IBD (50 with ulcerative colitis, 41 with Crohn’s disease, 18 patients with unclassified colitis), of which 36 patients were examined in dynamics for 0.5–1 years, and 53 surveyed comparison groups. Taking into account the observation in dynamics in 109 cases, the presence of exacerbation of IBD was established and in 36 cases — remission of the diseases. The electrical and viscoelastic parameters of erythrocytes were studied by dielectrophoresis. The level of fecal calprotectin was determined by ELISA (R-Biopharm, Germany).</p></sec><sec><title>Results</title><p>Results. Differentiating values have been established for a number of erythrocyte parameters: average cell diameter, polarizability at a frequency of 106 Hz, the velocity of movement of cells towards electrodes, amplitude of erythrocyte deformation at a frequency of 106 Hz, the summarized indicators of rigidity, viscosity, electrical conductivity, position of the crossover frequency and the level of fecal calprotectin to distinguish patients with IBD in stages of exacerbation and remission. The proposed method for the combined use of erythrocyte parameters and the level of fecal calprotectin provided sufficient diagnostic accuracy: sensitivity 91.9%, specificity 93.1%, accuracy index 92.3%. The advantages of this approach are minimally invasiveness, high productivity, independence of the definition from the qualifications and experience of a specialist, low cost and labor intensity, and acceptability for the patient. This approach allows to establish the presence of exacerbation or remission, regardless of the nosological form of IBD.</p></sec><sec><title>Conclusion</title><p>Conclusion. The combined use of electrical and viscoelastic parameters of erythrocytes and the level of fecal calprotectin is promising for determining the activity of the disease in patients with IBD.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника</kwd><kwd>диагностика</kwd><kwd>способ</kwd><kwd>активность заболевания</kwd><kwd>эритроциты</kwd><kwd>диэлектрофорез</kwd><kwd>фекальный кальпротектин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inflammatory bowel disease</kwd><kwd>diagnosis</kwd><kwd>method</kwd><kwd>activity of the disease</kwd><kwd>erythrocytes</kwd><kwd>dielectrophoresis</kwd><kwd>fecal calprotectin</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">Клинические рекомендации «Язвенный колит» (утв.
