Цель исследования. Сформулировать эффективную методологию и создать действенные решающие правила прогноза характера течения заболеваний органов пищеварения в фазу острых явлений патологического процесса на примере ЯК для обоснования на основе прогностического вывода объема, содержания и интенсивности индивидуальной терапии. Материал, методы и результаты исследования. Обследовано 366 больных ЯК (мужчин - 213, женщин - 153). Возраст больных: от 18 до 78 лет. Больных с дистальным колитом - 211, с левосторонним колитом - 68, с субтотальным - 66, с тотальным - 21. Острое течение ЯК имело место у 167 больных. У всех остальных 199 больных наблюдался рецидив хронического течения ЯК. При этом у 140 больных имелось редкое рецидивирование заболевания, часто рецидивирующее течение - у 59 больных. Хроническое непрерывно рецидивирующее течение ЯК из 59 больных мы наблюдали у 14 больных. Использование математических методов прогнозирования в виде неоднородной последовательной процедуры, дискриминантного и кластерного анализов, использованных в построении прогностической программы, позволило выделить из большого числа клинических признаков ЯК 28 наиболее значимых для прогноза симптомов острой фазы заболевания и дать им соответствующую количественную характеристику. Разработанная компьютерная программа, индивидуально суммирующая прогностические коэффициенты каждого больного, обеспечивает клинициста информацией о степени риска развития «неблагоприятного» течения болезни (осложнения, гормональная резистентность, гормональная зависимость, внекишечные проявления и др.) или предполагает «благоприятное» течение ЯК: быстрый адекватный ответ организма на стандартные лечебные мероприятия. Заключение. Материалы статьи позволяют с высокой точностью получать прогноз течения ЯК в острую фазу заболевания, что может послужить методологической и методической основой для дальнейшего поступательного научного движения при решении более значительных и глобальных задач в гастроэнтерологии.</p></abstract><trans-abstract xml:lang="en"><p>The creation of a system for predicting the nature of the course of the acute phase of ulcerative colitis (UC) would be able to block possible complications and other life-threatening variants of the development of the pathological process with timely preventive therapy. The purpose of the study. To formulate an effective methodology and create effective decisive rules for predicting the nature of the course of diseases of the digestive system in the phase of acute phenomena of the pathological process on the example of UC for justification based on the prognostic conclusion of the volume, content and intensity of individual therapy. Material, methods and results of the study. 366 patients with UC were examined (men - 213, women - 153). Age of patients: from 18 to 78 years. Patients with distal colitis - 211, with left-sided colitis - 68, with subtotal - 66, with total - 21. Acute course of UC occurred in 167 patients. All other 199 patients had a relapse of the chronic course of UC. At the same time, 140 patients had a rare recurrence of the disease, and 59 patients often had a recurrent course. We observed a chronic continuously recurrent course of UC in 14 patients out of 59 patients. The use of mathematical forecasting methods in the form of an inhomogeneous sequential procedure, discriminant and cluster analyses used in the construction of the prognostic program made it possible to identify from a large number of clinical signs of UC 28 the most significant symptoms of the acute phase of the disease for prognosis and to give them an appropriate quantitative characteristic. The developed computer program, which individually summarizes the prognostic coefficients of each patient, provides the clinician with information about the degree of risk of developing an “unfavorable” course of the disease (complications, hormonal resistance, hormonal dependence, extra-intestinal manifestations, etc.) or assumes a “favorable” course of UC: a rapid adequate response of the body to standard therapeutic measures. Conclusion. The materials of the article allow us to accurately predict the course of UC in the acute phase of the disease, which can serve as a methodological and methodological basis for further progressive scientific movement in solving more significant and global problems in gastroenterology</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прогноз язвенного колита</kwd><kwd>лечение на основе прогноза</kwd><kwd>профилактика осложнений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ulcerative colitis prognosis</kwd><kwd>prognostic treatment</kwd><kwd>prognostic prevention of complications</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">Child C.G., Turcotte J.
