В исследование включены 377 больных ПсА (185 мужчин и 192 женщины); средний возраст пациентов составлял 47,6±12,4 года, длительность псориаза (ПсО) – 206,8±156,3 мес, ПсА – 84,8±84,6 мес. Анализировались клинико-лабораторные данные после 6 месяцев лечения. Пациентам проводилось стандартное клиническое обследование, выявляли наличие коморбидных заболеваний по Международной классификации болезней 10-го пересмотра, определяли число пациентов, достигших минимальной активности болезни (МАБ), влияние на достижение МАБ ряда показателей.</p></sec><sec><title>Результаты</title><p>Результаты. К 6-му мес. наблюдения медиана числа болезненных суставов составила 3,0 [0,0; 8.0], числа припухших суставов – 1,0 [0,0; 5,0], уровня С-реактивного белка (СРБ) – 4,3 (0,0–90,6) мг/л, индекса LEI (Leeds Enthesitis Index) – 0,0 (0,0–6,0), среднее значение индекса массы тела (ИМТ) составило 27,6±5,2 кг/м2. Было выявлено 273 (72%) больных с ИМТ&lt;30 кг/м2, 75 (19,9%) – с 30≤ИМТ&lt;35 кг/м2, 29 (7,7%) – с ИМТ≥35 кг/м2. У 264 (70,0%) из 377 больных наблюдалась «легкая» форма ПсО с площадью поражения кожи (BSA, Body Surface Area) ≤3%, у 96 (25,5%) – среднетяжелый ПсО (3%&lt;BSA≤10%), у 17 (4,5%) – тяжелый ПсО (BSA&gt;10%). Критериям МАБ соответствовали 82 (21,8%) больных, коморбидные заболевания выявлены у 152 (40%).</p><p>Был выполнен многомерный анализ с предварительным отбором изучаемых показателей по коэффициентам Спирмена; выявлен ряд показателей, отрицательно коррелирующих с достижением МАБ, включая СРБ (р=0,0001), LEI (р=0,001), артериальную гипертензию (АГ) (р=0,08), BSA (р=0,063) и ИМТ (р=0,289).</p><p>Далее было получено дискриминантное правило, позволяющее прогнозировать возможность достижения МАБ: 0,046×(СРБ, мг/л) + 0,470×LEI + 0,527×(АГ) + 0,451×(BSA) + 0,237×(ИМТ) ≤ 1,184, где LEI – число болезненных точек согласно индексу LEI; отсутствие АГ – 0, наличие АГ – 1; BSA≤3% – 1, 3%&lt;BSA≤10% – 2, BSA&gt;10% – 3; ИМТ&lt;30 кг/м2 – 0, 30≤ИМТ&lt;35 кг/м2 – 1, ИМТ≥35 кг/м2 – 2. Итоговое значение выражения ≤1,184 указывает на высокую вероятность достижения МАБ у больного ПсА.</p><p>Для иллюстрации силы факторов, вошедших в многофакторную модель способа определения возможности достижения МАБ, построен график ROC-кривой, отражающей соотношение чувствительности и специфичности указанных факторов. Площадь под ROC-кривой составила 0,76, что позволяет оценить прогностическую точность модели как высокую (95%-й доверительный интервал: 0,71–0,81; р=0,26).</p><p>Для выбранного суммарного значения дискриминантной функции 1,184 чувствительность составила 85,4%, специфичность – 59,3%.</p></sec><sec><title>Выводы</title><p>Выводы. Разработанный способ оценки возможности достижения МАБ у больных ПсА, включающий определение комплекса показателей (СРБ, LEI, наличие у пациента АГ и ожирения, а также тяжесть ПсО), позволяет оценить перспективы лечения больных ПсА и стимулирует врача и пациента модифицировать факторы, включенные в данную формулу.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim – to develop a method for predicting the effectiveness of psoriatic arthritis (PsA) therapy.</p><sec><title>Methods</title><p>Methods. 377 PsA patients (pts) were examined: (М/F 185/192). Pts’ age 47.6±12.4 years, psoriasis (PsO) duration 206.8±156.3 months, PsA duration – 84.8±84.6 months. Pts underwent standard clinical examination, the analysis included detection of comorbidities according to ICD-10. Pts were evaluated for achieving minimal disease activity (MDA). Data of visit 2 (6 months of treatment) were analysed.</p></sec><sec><title>Results</title><p>Results. At 6 months of treatment tender joint count was 3,0 [0.0; 8.0], swollen joint count – 1,0 [0.0; 5.0], C-reactive protein (CRP) – 4,3 (0.0–90.6) mg/l, LEI (Leeds Enthesitis Index) – 0,0 (0.0–6.0), body mass index (BMI) – 27.6±5.2 kg/m2. 273 (72%) pts had BMI&lt;30 kg/m2, 75 (19.9%) pts – 30≤ BMI&lt;35 kg/m2, 29 (7.7%) pts – BMI≥35 kg/m2. Mild PsO (BSA≤3%) was found in 264 (70.0%) of 377 pts, moderate (3%&lt;BSA≤10%) – in 96 (25,5%) pts, severe PsO (BSA&gt;10%) – in 17 (4.5%) pts. 82 (21.8%) pts met the MDA criteria. Comorbid diseases were found in 152 (40%) pts.</p><p>Multivariate analysis was performed and the following parameters were revealed that negatively correlate with MDA achievement – CRP (p=0.0001), LEI (p=0.001), arterial hypertension (AH) (p=0.08), BSA (p=0.063), BMI (p=0.289). A discriminant rule was obtained that makes it possible to predict the possibility of MDA achievement: 0.046×(CRP, mg/l) + 0.470×LEI + 0.527×(AH) + 0.451×(BSA) + 0.237×(BMI) ≤1.184.</p><p>This formula includes the values of CRP, LEI, AH (no AH – 0 points, with AH – 1 point), BSA (BSA≤3% – 1 point, 3%&lt;BSA≤10% – 2 points, BSA&gt;10% – 3 points), BMI (BMI&lt;30 kg/m2 – 0, 30≤BMI&lt;35 kg/m2 – 1 point, BMI≥35 kg/m2 – 2 points). When the expression value is ≤1.184, the achievement of MDA in PsA pts is predicted.</p><p>The area under the ROC curve is 0.76, which makes it possible to estimate the predictive accuracy of the model as high (95% CI: 0.71–0.81; p=0.26. For the selected total value of the discriminant function 1.184, sensitivity is 85.4%, specificity – 59.3%.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed method for predicting the MDA achievement in PsA pts including the following indicators: CRP, LEI, the presence of hypertension and obesity, severity of PsO – makes it possible to predict the treatment outcome in PsA pts and stimulates both the physician and the patient to modify the factors included in this formula.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>псориатический артрит</kwd><kwd>минимальная активность болезни</kwd><kwd>способ прогнозирования эффективности фармакотерапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>psoriatic arthritis</kwd><kwd>minimal disease activity</kwd><kwd>method of predicting the effectiveness of psoriatic arthritis pharmacotherapy</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование проводилось в рамках выполнения фундаментальной научной темы «Эволюция аксиальных спондилоартритов на основе комплексного динамического изучения молекулярно-биологических, молекулярно-генетических, клинико-визуализационных факторов прогрессирования заболевания, качества жизни, коморбидности и таргетной инновационной терапии», утвержденной ученым советом ФГНБУ НИИР им.
