ЭР расценивалась как значение индекса Шредера = 0 баллов. У всех пациентов оценивались эндоскопические и морфологические показатели исходно, клинико-лабораторные данные исходно и в динамике через 3 мес. после лечения, после чего были выявлены ранние предикторы развития ЭР в течение 12 мес. с созданием прогностической бинарной логистической регрессионной модели. Чувствительность, специфичность и точность модели оценивались как высокие при значениях ≥ 90,0%, умеренные — 80,0–89,9%.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: при динамическом наблюдении 72 пациентов ЭР через 12 мес. развилась у 26/72 (36,1%). ЭР чаще развивалась у пациентов без лихорадки (25/58 (43,1%) против 1/14 (7,1%), р = 0,013), при наличии легкой атаки при манифестации ЯК (13/24 (54,2%) против 13/48 (27,1%) при среднетяжелой атаке, р = 0,037), достигших клинической ремиссии через 3 мес. терапии (21/47 (44,7%) против 5/25 (20,0%), р = 0,043). Пациенты с избыточной массой тела (1/11 (9,1%) против 24/61 (41,0%), р = 0,048), диарейным синдромом на момент включения (20/64 (31,3%) против 6/8 (75,0%), р = 0,023), с сохранением положительного результата кала на скрытую кровь через 3 мес. (3/20 (15,0%) против 22/43 (51,2%), р = 0,012) достигали ЭР через 12 мес. реже. Пациенты с тотальным ЯК (7/30 (23,3%) против 19/42 (45,2%), р = 0,056) и умеренной эндоскопической активностью (11/41 (26,8%) против 15/31 (48,4%), р = 0,059) имели тенденцию к более редкому развитию ЭР через 12 мес. У пациентов с ЭР медиана гемоглобина через 3 мес. лечения были выше — 128,5 (124,5–133,5) г/л против 127,0 (124,0–130,0) г/л у пациентов без ремиссии (р = 0,022), а значения ФК — значимо ниже — 50 (25–104) мкг/г против 215 (50–290) мкг/г (р = 0,005). После пошагового отбора признаков итоговая регрессионная модель содержала: наличие избыточной массы тела исходно (скорректированное отношение шансов (СОШ) — 0,026; 95% доверительный интервал (ДИ): 0,002–0,374; р = 0,007) и панколита исходно (СОШ 0,076; 95% ДИ: 0,013–0,445; р = 0,004), отсутствие лихорадки (СОШ 17,49; 95% ДИ: 1,203–254,206; р = 0,036), наличие умеренной эндоскопической активности на момент включения (СОШ = 0,204; 95% ДИ: 0,035–1,191, р = 0,07). Чувствительность модели составила 90,9% (95% ДИ: 78,9–100,0%), специфичность — 82,6% (95% ДИ: 67,1–98,1%), общая точность — 86,7% (95% ДИ: 76,7–96,6%), площадь под ROC-кривой — 0,800 ± 0,052 (95% ДИ: 0,699–0,901), псевдо-R2 Найджелкерка 54,0% (р &lt; 0,001). </p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: созданная модель демонстрирует высокую чувствительность и умеренную специфичность, что после валидации позволит применять её в клинической практике как вспомогательный прогностический инструмент.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to identify predictors of ER after 12 months of therapy in patients with mild-to-moderate UC based on clinical, laboratory, endoscopic, and histopathological parameters.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: this prospective study enrolled patients with mild-to-moderate UC after excluding intestinal infections. Clinical, laboratory, endoscopic, and histological parameters were assessed at baseline and during follow-up. Early predictors of ER within 12 months were identified, and a predictive regression model was developed.</p></sec><sec><title>RESULTS</title><p>RESULTS: longitudinal follow-up of 72 patients revealed that unfavorable predictors of ER at 12 months included: excess body weight - observed in 9.1% of patients who achieved ER versus 41.0% of non-responders (adjusted odds ratio (aOR) 0.026; 95% confidence interval (CI): 0.002-0.374; p=0.007), and pancolitis - 23.3% versus 45.2% (aOR 0.076; 95% CI: 0.013-0.445; p=0.004). The protective factor was absence of fever at baseline (43.1% in ER group vs 7.1% in non-ER group; aOR 17.49; 95% CI: 1.203-254.206; p=0.036). Moderate endoscopic activity at inclusion showed no significant association with outcomes (p=0.077). The developed model (p&lt;0.001) demonstrated an AUC of 0.800±0.052 (95% CI: 0.699–0.901), with 90.9% sensitivity, 82.6% specificity, and 80.6% overall accuracy.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: excess body weight and pancolitis at baseline were negative prognostic markers for achieving ER at 12 months, whereas the absence of fever at baseline increased the likelihood of this outcome. However, endoscopic activity did not show a statistically significant impact in the multivariate analysis. The model exhibits high sensitivity and moderate specificity, suggesting its potential utility as a supplementary predictive tool in clinical practice following validation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эндоскопическая ремиссия</kwd><kwd>язвенный колит</kwd><kwd>прогнозирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endoscopic remission</kwd><kwd>ulcerative colitis</kwd><kwd>prediction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено за счет гранта Российского научного фонда №24-25-20127 (https://rscf.ru/ project/24-25-20127/) и Санкт-Петербургского научного фонда на базе ФГБОУ ВО СЗГМУ им.
