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

The JAK inhibitor tofacitinib (TOFA) blocks the intracellular signaling pathway that activates the synthesis of cytokines and mediators involved in the development of pain and central sensitization (CS), which determines the rapid analgesic effect. However, it is not clear how pain reduction is associated with achieving low activity in rheumatoid arthritis (RA).The aim of the study was to assess the relationship between the early clinical response to tofacitinib and a decrease in rheumatoid arthritis activity after 3 and 6 months.Material and methods. The study group consisted of 88 RA patients (age – 53±11.5 years; 79.3% of women) who received basic anti-inflammatory drugs (59.5% – methotrexate, 19.8% – leflunomide) and who were prescribed TOFA in a dose 10 mg/day. Seropositivity for rheumatoid factor was 89.8%; the value of the DAS28 index is 5.2±1.2. The severity of pain was assessed using the Brief Pain Inventory questionnaire, the neuropathic component of pain (NCP) – using the PainDETECT questionnaire, signs of CS – using the Central Sensitization Inventory (CSI) questionnaire in the early stages after the administration of TOFA, RA activity – using the DAS28-CRP index after 3 and 6 months.Results. The mean severity of pain at baseline was 5.3±2.0 on the visual analogue scale (VAS); 51.1% of patients had signs of CS (CSI>40), 15.9% had NCP (PainDETECT>18). 7 days after the start of therapy, there was a significant decrease in pain – to 4.1±1.8 according to VAS (p

The paper presents the materials of the Russian Arthritis Registry (OREL) that includes 3276 patients from 11 Russian Federation's largest research-and-practical centers situated in Moscow, Saint Petersburg, Novosibirsk, Kazan, Tula, Yaroslavl, Tyumen. It discusses the main goals of setting up registries, compares the results of an analysis of the data available in the Russian Registry OREL and registries of European countries and the USA. The findings suggest that there is non-uniform information on clinical, laboratory, and instrumental parameters in the national registers of a number of European countries and the USA. According to its basic characteristics, the Russian Registry OREL compares favorably with a number of other registries in the completeness of data collection, which allows a general idea of rheumatoidarthritis (RA) patients in Russia. For further development of the OREL Registry, it is necessary to concentrate our attention on the following main areas: to improve the quality of filling out documents; to follow-up patients receiving different RA therapy regimens according to the guidelines of the Association of Rheumatologists of Russia for the treatment of RA; to conduct in-depth studies of comorbidity, primarily depressive disorders; to analyze adverse reactions that make RA therapy difficult; to actively use modules for patients' self-rating of their condition; to develop nursing care, etc.
