В исследование включен 41 больной псориатическим артритом, диагноз соответствовал критериям CASPAR. 40 пациентам проводилась МРТ крестцово-подвздошных суставов. Активный сакроилиит при МРТ (МРТ-СИ) диагностировался в режиме STIR при выявлении отека костного мозга (ОКМ) как минимум на двух последовательных срезах или при наличии 2 и более зон ОКМ на одном срезе. Всем больным, включенным в исследование, назначался ТОФА в таблетках по 5 мг два раза в сутки с возможным увеличением дозы после 12 недель терапии до 10 мг два раза в сутки. В конце исследования, через 24 недели после начала лечения ТОФА, 35 больным повторно была проведена МРТ крестцово-подвздошных суставов.Результаты. Исходно МРТ-СИ был выявлен у 14 из 40 (35%) пациентов: у 9 – двусторонний, у 5 – односторонний. После 24 недель терапии ТОФА активный СИ был обнаружен у 4 из 35 (11,4%) обследованных больных: у 1 пациента с исходным двусторонним поражением, у 2 – с односторонним; у 1 пациента, исходно не имевшего МРТ-СИ, он развился впервые. Уменьшение числа больных с активным сакроилиитом статистически значимо (р=0,017). До назначения ТОФА МРТ-СИ (остеит) выявлен в 23 из 80 (28,8%) крестцово-подвздошных суставах, через 24 недели – в 5 из 70 (7,1%; р=0,001). На фоне лечения отмечалось существенное снижение активности спондилита, и через 24 недели медианы индексов BASDAI и ASDAS-СРБ уменьшились с 6,0 [4,2;7,0] до 1,4 [0,6;3,2] и с 3,8 [2,8;4,4] до 1,5 [1,0;2,1] соответственно (р=0,001 для обоих сравнений). При этом значимо уменьшилось число пациентов с высокой активностью спондилита. До начала терапии ТОФА высокая активность по BASDAI наблюдалась у 90,2%, низкая – у 9,8% больных; к концу исследования – у 13,5% и 86,5% соответственно (p=0,001). По индексу ASDAS-СРБ очень высокая активность спондилита исходно выявлена у 61%, высокая – у 29,2%, низкая – у 9,8% пациентов. Через 24 недели очень высокой активности по ASDAS-СРБ выявлено не было (p=0,001), высокая активность отмечалась у 23,1%, умеренная и низкая – у 30,7% и 46,2% больных соответственно (p=0,001 для обоих сравнений). У больных с МРТ-СИ по сравнению с группой без МРТ-СИ исходно было статистически значимо большее число пальцев с дактилитом – 2 [0; 4] и 0 [0; 2] (р=0,04), а также более высокая СОЭ – 47 [26; 76] и 20 [6; 37] мм/ч соответственно (р=0,02). К концу исследования эти различия нивелировались, медиана числа пальцев с дактилитом составляла 0 [0; 0] и 0 [0; 0] (р=0,48), СОЭ – 12 [6; 16] и 8 [6; 16] мм/ч соответственно (р=0,78).Выводы. ТОФА оказывает значимое влияние на динамику активного МРТ-СИ у больных аксиальным псориатическим артритом и является эффективным препаратом для лечения пациентов с высокой активностью спондилита. ТОФА эффективен у пациентов с МРТ-СИ, имеющих дактилиты и высокие значения СОЭ.</p></abstract><trans-abstract xml:lang="en"><p>Axial involvement in psoriatic arthritis is quite common. There is no data on the use of tofacitinib, an oral Janus kinase inhibitor, in psoriatic arthritis patients with axial involvement, nor is there any data on its effect on active MRI sacroiliitis.The aim of the study was to assess the effect of tofacitinib therapy on the dynamics of active MRI sacroiliitis in psoriatic arthritis patients.Materials and methods. 41 patients with active psoriatic arthritis fulfilling the CASPAR criteria were included. Median age was 41.0 [34; 50] years old, median disease duration was 6.0 [3; 10] years. Apart from a standard clinical examination, 40 patients underwent sacroiliac joint MRI on scanner Siemens General Electric 1.5 TESLA. Bone marrow edema on MRI (STIR) with one lesion on two consecutive slices or at least two lesions on a single slice, was considered active MRI sacroiliitis. Tofacitinib was given in 5 mg tablets twice a day with a possible dose increase up to 10 mg twice a day after 12 weeks of therapy. At the end of study, over a period of 24 weeks, sacroiliac joint MRI examination was repeated in 35 patients.Results. Prior to tofacitinib therapy, active MRI sacroiliitis was detected in 14 of 40 (35%) patients: bilateral – in 9 patients, unilateral – in 5 patients. At the end of 24 weeks therapy, active MRI sacroiliitis was detected in 4 of 35 (11.4%) patients observed: in 1 patient with baseline bilateral MRI sacroiliitis and in 2 patients with unilateral MRI sacroiliitis. 1 patient showed negative dynamics, that is, development of active MRI sacroiliitis (absent at baseline). The decrease in number of active MRI sacroiliitis patients is statistically significant (p=0.017). At baseline, inflammatory changes were detected in 23 of 80 (28.8%) sacroiliac joints, after 24 weeks of therapy they were found in 5 of 70 (7.1%; p=0.001) sacroiliac joints observed. During the treatment period, there was a significant decrease in the initially high activity of spondylitis. After 24 weeks of treatment, median BASDAI decreased from 6.0 [4.2; 7.0] to 1.4 [0.6; 3.2], median ASDAS-CRP from 3.8 [2.8; 4.4] to 1.5 [1.0; 2.1] (p=0.001 for both comparisons). Prior to tofacitinib therapy, high activity according to BASDAI was observed in 90.2% of patients, low activity – in 9.8%; at the end of study – in 13.5% and 86.5% of patients, respectively (p=0.001). At baseline, very high activity by ASDAS-CRP was detected in 61% of patients, high activity – in 29.2%, low activity – in 9.8% of patients. At the end of study there weren’t any patients with very high activity by ASDAS-CRP (p=0.001), high activity remained in 23.1%, moderate and low activity – in 30.7% and 46.2% of patients, respectively (p=0.001 for both comparisons). Significant differences between baseline symptoms in patients with MRI sacroiliitis and without it were defined by number of digits with dactylitis – 2 [0; 4] and 0 [0; 2] (p=0.04) and by ESR values – 47 [26; 76] and 20 [6; 37] mm/h (p=0.02). These parameters were higher in MRI sacroiliitis subgroup. By the end of study, these differences leveled out: the number of digits with dactylitis decreased to 0 [0; 0] and 0 [0; 0] (р=0.48), ESR – to 12 [6; 16] and 8 [6; 16] mm/h, respectively (p=0.78).Conclusion. Tofacitinib therapy shows high efficacy in reducing active MRI sacroiliitis and decreasing activity of axial involvement in psoriatic arthritis patients. The use of tofacitinib in patients with active MRI sacroiliitis as well as dactylitis and increased ESR levels demonstrated its high efficacy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тофацитиниб</kwd><kwd>сакроилиит при МРТ</kwd><kwd>аксиальный псориатический артрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tofacitinib</kwd><kwd>MRI sacroiliitis</kwd><kwd>axial psoriatic arthritis</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование проводилось в рамках выполнения научной темы АААА-А19-119021190147-6, 0514-2019-009 «Патогенетические особенности и персонифицированная терапия анкилозирующего спондилита и псориатического артрита», утвержденной Ученым Советом ФГБНУ НИИР им.
