Очень ранний клинический ответ при лечении ингибитором янус-киназ тофацитинибом у больных активным ревматоидным артритом: динамика боли и элементов центральной сенситизации

Janus kinase (JK) inhibitors block the intracellular signaling pathways that are responsible for the synthesis of proinflammatory cytokines and mediators, which in turn cause the activation of pain receptors and central sensitization (CS). It is suggested that JK inhibitors can rapidly eliminate pain and reduce the severity of CS.Objective: to evaluate the effect of the JK inhibitor tofacitinib (TOFA) on the intensity of pain and the signs of CS in patients with active rheumatoid arthritis (RA) at 7 and 28 days after therapy initiation.Patients and methods. A study group consisted of 39 patients (79.5% female) (mean age 50.9±11.1 years) with RA (DAS28 5.8±0.6). Of these, 89.7% were seropositive for rheumatoid factor; 82.0% took methotrexate and 18.0% received leflunomide. All the patients were prescribed TOFA 5 mg twice daily due to the inefficacy or intolerance of biological agents. The investigators estimated pain intensity using a Brief Pain Inventory (BPI), rated the presence of a neuropathic pain component (NPC) with the PainDETECT questionnaire, and assessed the signs of CS with the Central Sensitization Inventory (CSI) during the first 4 weeks after TOFA administration.Results and discussion. The patients initially experienced moderate or severe pain (the mean scores of 5.33±2.51 on the numerical rating scale (NRS) included in BPI); 53.8% had signs of CS (CSI scores of ≥40); 17.9% had signs of a NPC (PainDETECT scores of >18). Already on day 7 after the start of TOFA administration, there was a statistically significant decrease in the mean NRS pain intensity scores to 4.06±2.2 (p=0.01) and by 29.4±17.9%, as shown by the patient's assessment of the analgesic effect of therapy (BPI), as well as the severity of CS, namely a decrease in the mean NRS pain score to 35.9±11.2 (p=0.01). On 28 days, the effect became better: there was a reduction in the level of NRS pain to 2.32±1.57 (p<0.001), in pain according to the patient's assessment of the analgesic effect of therapy to 43.6±29.6%; in the median PainDETECT score to 2.5 [0; 8.7] (p<0.001); and in CSI scores to an average of 26.4±13.9 (p <0.001). No serious adverse reactions were noted.TOFA has a rapid analgesic effect, which allows it to be considered as a chooser for pathogenetic therapy in patients with active RA and severe pain, especially in the presence of CS signs and secondary fibromyalgia. Undoubtedly, large-scale, long-term controlled studies with a wider range of estimated parameters are required to clarify the therapeutic potential of TOFA in this patient category. The limitation of this investigation was its open observer design pattern.Conclusion. The use of the JK inhibitor TOFA can achieve a rapid analgesic effect, inter alia due to its effect on CS and NPC.Ингибиторы янус-киназ (ЯК) блокируют внутриклеточные сигнальные пути, отвечающие за синтез провоспалительных цитокинов и медиаторов, которые, в свою очередь, вызывают активацию болевых рецепторов и развитие центральной сенситизации (ЦС). Предполагается, что ингибиторы ЯК могут быстро устранять боль и уменьшать выраженность ЦС.Цель исследования – оценить влияние ингибитора ЯК тофацитиниба (ТОФА) на выраженность боли и признаки ЦС у больных активным ревматоидным артритом (РА) через 7 и 28 дней после начала терапии.Пациенты и методы. Исследуемую группу составили 39 больных РА (средний возраст 50,9±11,1 года, 79,5% женщин), DAS28 – 5,8±0,6. Из них 89,7% были серопозитивными по ревматоидному фактору, 82,0% получали метотрексат и 18,0% – лефлуномид. Всем пациентам был назначен ТОФА 5 мг 2 раза в день в связи с неэффективностью или непереносимостью генно-инженерных биологических препаратов. Оценивались выраженность боли с помощью опросника BPI (Brief Pain Inventory), наличие невропатического компонента боли (НКБ) с помощью опросника PainDETECT и признаков ЦС с помощью опросника CSI (Central Sensitization Inventory) в первые 4 нед после назначения ТОФА.Результаты и обсуждение. Пациенты исходно испытывали умеренную или выраженную боль (в среднем 5,33±2,51 по числовой рейтинговой шкале – ЧРШ, включенной в BPI), 53,8% имели признаки ЦС (CSI ≥40), 17,9% – признаки НКБ (PainDETECT >18). Уже через 7 дней после начала приема ТОФА отмечалось статистически значимое снижение интенсивности боли в среднем до 4,06±2,2 по ЧРШ (р=0,01) и на 29,4±17,9% по оценке анальгетического эффекта терапии пациентом (BPI), а также выраженности ЦС – уменьшение значения CSI в среднем до 35,9±11,2 (р=0,01). Через 28 дней эффект усилился: наблюдалось снижение уровня боли по ЧРШ до 2,32±1,57 (р<0,001), боли по оценке анальгетического эффекта терапии пациентом до 43,6±29,6%, медианы значения PainDETECT до 2,5 [0; 8,7] (р<0,001), показателя CSI в среднем до 26,4±13,9 (р<0,001). Серьезных неблагоприятных реакций не отмечено. ТОФА обладает быстрым анальгетическим эффектом, что позволяет рассматривать его как средство выбора при проведении патогенетической терапии у больных активным РА с выраженной болью, особенно при наличии признаков ЦС и вторичной фибромиалгии. Несомненно, требуются большие по масштабу длительные контролируемые исследования с более широким кругом оцениваемых параметров для уточнения лечебного потенциала ТОФА у этой категории пациентов. Ограничением настоящего исследования явился его открытый наблюдательный характер.Заключение. Использование ингибитора ЯК ТОФА позволяет достичь быстрого анальгетического эффекта, в том числе за счет влияния на ЦС и НКБ

Time course of changes in the clinical and instrumental manifestations of coxitis in patients with ankylosing spondylitis during golimumab therapy: a GO-COX study. Preliminary results

Objective: to evaluate the effect of golimumab (GLM) on the clinical, functional, and instrumental manifestations of coxitis in ankylosing spondylitis (AS).Subjects and methods. The non-interventional prospective multicenter cohort study GO-COX conducted in the medical centers of the Russian Federation enrolled 39 patients with AS (meeting the modified New York criteria) and coxitis with BASRI-hip score 0–2, who were prescribed GLM as the first biologic agent at a dose of 50 mg per month. The patient's health status was assessed using the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath Ankylosing Spondylitis Metrology Index (BASMI), the Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein (ASDAS-CRP), and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) before and at 6 and 12 months after GLM treatment initiation. Based on the data of radiographs (the Bath Ankylosing Spondylitis Radiology Hip Index (BASRI-hip) scoring system), ultrasonography (USG), and STIR and T1 magnetic resonance imaging (MRI), the investigators assessed the manifestations of coxitis. The planned follow-up duration was 2 years. This paper includes 12-month follow-up results in 22 patients.Results and discussion. At 12 weeks of GLM therapy, there were significant positive index changes: a decrease in BASDAI by an average of 3.28±1.62, in ASDAS-CRP by 2.20±0.95, in BASFI by 2.52±2.09, and in BASMI by 1.41±1.50 (p<0.0001). One year after GLM therapy initiation, the BASRI-hip values remained unchanged; 40 to 60% of patients had no MRI and USG signs of coxitis.Conclusion. At 12 weeks, GLM therapy in patients with AS and coxitis provided a reduction in the clinical and instrumental signs of coxitis, as evidenced by MRI and USG (a significant decline in the proportion of patients with subchondral bone edema and intraarticular effusion), and also effectively suppressed other manifestations of inflammatory activity
