On 30 May, 2024, an expert meeting was held to update the approaches for the treatment of axial spondyloarthritis (axSpA). A new approach to the treatment of axSpA was considered, which consists of depleting autoreactive TRBV9+ T- lymphocytes by introducing a monoclonal antibody – the drug seniprutug. The value of the drug seniprutug in the treatment of the disease was discussed and key aspects for the incorporation of the drug seniprutug into real-world clinical rheumatological practice were agreed.

Currently, a large number of highly effective biologic disease modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) are used for the treatment of rheumatoid arthritis (RA). However, in addition to effectiveness, it is necessary to evaluate the risk of adverse events (AEs) when using them.Objective: to determine the predictors of bDMARDs and tsDMARDs discontinuation due to AEs in patients with RA.Patients and methods. The study included 661 patients with RA who took bDMARDs and tsDMARDs. The search for predictors of targeted therapy discontinuation due to AEs was carried out in two stages. At the first stage, using the Kaplan-Meier method, we selected indicators that showed the greatest significant single-factor relationship with the duration of retention on therapy. At the second stage, significant independent indicators were obtained by iterative selection of variables within the multivariate proportional risk model according to Cox.Results and discussion. The presence of rheumatoid nodules (p

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

Objective: to study the efficacy, immunogenicity, and safety of a 23-valent pneumococcal polysaccharide vaccine (PPSV-23) in patients with rheumatoid arthritis (RA) receiving disease-modifying antirheumatic drugs (DMARDs) and biologic agents (BAs) during a 5-year follow-up.Patients and methods. The investigation included 79 RA patients with a recent history of ≥2 episodes of lower respiratory tract infections (bronchitis, pneumonia). A single dose (0.5 ml) of PPSV-23 was administered subcutaneously during continued methotrexate/leflunomide therapy or 28–30 days before using TNF-α inhibitors. All the patients were followed up during the first year; 39 patients at 24 months (Visit 5), 13 at 36 months (Visit 6), 23 at 48 months (Visit 7), and 18 at 60 months (Visit 8).Results and discussion. RA patients receiving various therapies were noted to have a marked positive immune response to PPSV-23, which was manifested by a significant increase in the postimmunization response coefficient. Vaccination responses were recorded in 61% of the patients with RA. The level of postvaccination responses tended to decrease at the 4-year follow-up. Only one case of community-acquired pneumonia of unknown etiology was detected at 5 years of follow-up.Conclusion. The data obtained by the authors for the first time in the 5-year prospective study indicate the sufficient and long-term immunogenicity, high efficacy, and safety of PPSV-23 in RA patients treated with DMARDs and BAs. Further clinical trials are needed to clarify the influence of various factors on the efficacy and immunogenicity of PPSV-23 and on the degree of their correlation in patients with RA.Objective: to study the efficacy, immunogenicity, and safety of a 23-valent pneumococcal polysaccharide vaccine (PPSV-23) in patients with rheumatoid arthritis (RA) receiving disease-modifying antirheumatic drugs (DMARDs) and biologic agents (BAs) during a 5-year follow-up.Patients and methods.

Tofacitinib (TOFA), a representative of a new class of targeted synthetic disease-modifying antirheumatic drugs (s-DMARD), is a promising drug for treating rheumatoid arthritis (RA) and other immune inflammatory diseases.Objective: to evaluate the efficiency and safety of therapy with TOFA in combination with methotrexate (MTX) and other s-DMARDs in real clinical practice in patients with active RA and previous ineffective therapy.Patients and methods. A 6-month Russian multicenter study of function and quality of life enrolled 101 patients with resistant RA: 18 men and 83 women; mean age, 51.03±11.28 years; mean disease duration, 105.4±81.43 months; rheumatoid factor-positive individuals (89.1%); and anticyclic citrullinated peptide antibody-positive ones (74.7%). 93 (92,1%) of these patients completed a 24-week study. TOFA was used as both second-line drug (after failure of therapy with s-DMARD) (n=74) and as a third-line drug (after failure of therapy with s-DMARDs and biological agents (BAs) (n=74). The tools RAPID3, HAQ, and EQ-5D were used to determine disease outcomes from a patient's assessment.Results. All the three tools demonstrated significant positive changes at 3–6 months following therapy initiation. RAPID3 scores for the status of a patient achieving a low disease activity or remission coincided with the mean DAS28-ESR and SDAI scores in 60% and 68% of cases, respectively. The achievement rates of the minimally clinically significant improvement (ΔHAQ≥0.22) and functional remission (HAQ≤0.5) at 6 months of TOFA therapy were 79.6 and 30.1%, respectively. The mean change value in EQ-5D scores over 6 months was -0.162±0.21. There were no significant between the groups of patients who used TOFA as a second- or third-line agent in the majority of indicators, except EQ-5D scores at 6 months.Conclusions. The results of our multicenter study using considerable Russian material confirmed the pronounced positive effect of TOFA used as a second-line agent (after s-DMARD failure) and a third-line agent (after s-DMARD and BA failure) on patients' assessment of disease activity, functional ability in daily life, and quality of life.

Russian and international clinical recommendations postulate the possibility of withdrawal of biological agents in patients with rheumatoid arthritis (RA) after the achievement of clinical remission. But it is not clear what would be the results of implementation of these recommendations in clinical practice.Patients and methods. In REMARCA (Russian invEstigation of MethotrexAte and biologicals for eaRly aCtive Arthritis) trial 78 patients (66 females, 12 males, median age 53 years, duration of disease 7 months at inclusion), who were resistant to high doses of subcutaneous (SC) methotrexate (MTX), were treated by combination therapy with SC MT and biologics (adalimumab, certolizumab or abatacept). Patients were investigated every 3 months using DAS28-ESR, SDAI, CDAI indices as disease activity measures.Results. 30 (38.5%) patients (from 78) continued combination therapy. In 47 (60.3%) after achievement of remission or low disease activity (LDA) the therapy was modified to one of two options: 1) in 21 (26.9%) patients doses of biologics were tapered, in some cases to zero; 2) in 26 (33.3%) patients single-step discontinuation of biologics was performed. After 6 months among 47 patients with modification of therapy 27 (57.4%) maintained remission or LDA, in 20 (42.6%) deterioration observed, including 6 (12.8%) patients who lost remission but remained in LDA, and 14 (29.8%) flared (activity increased to moderate or high levels). First modification option was significantly superior to second option regarding the maintaining remission or LDA.Conclusion. In terms of maximum preservation of the results, optimal modification of treatment strategy is the tapering of the dose by the gradual increase in the period between injections of biologics, at least 12 months after reaching the state LDA or clinical remission.

Tofacitinib (TOFA), a member of a new class of targeted synthetic disease-modifying antirheumatic drugs (DMARDs), is a promising medication for the treatment of rheumatoid arthritis (RA) and other immunoinflammatory diseases. The paper describes the Russian experi-ence with TOFA used to treat severe RA.Patients and methods. 101 RA patients (18 men and 83 women; mean age, 51.03±11.28 years; mean disease duration, 105.4±81.43 months) who were positive for rheumatoid factor (89.1%) and anti-cyclic citrullinated peptide antibodies (74.7%) and resistant to therapy with synthetic DMARDs (sDMARDs) (80.2%) and biological agents (19.8%) were given TOFA at a dose of 5 mg twice daily, which could be doubled if necessary. TOFA was used alone (n=9) or in combination with methotrexate (MT) (n=75) or other sDMARDs (n=17). The achievement of low disease activity (LDA) and clinical remission at 3 and 6 months of treatment by DAS28-ESR SDAI, and CDAI scores, and the indices of safety and tolerability were assessed.Results. A total of 93 (92.1%) of the 101 patients completed a 24-week period of the investigation. 8 (7.9%) patients prematurely discontinued TOFA after an average of 2.75±0.71 months. At the end of the study, the patients achieved the primary endpoint (LDA including remission) in terms of DAS28-ESR ≤3.2 (34.7%), SDAI ≤11 (47.5%), and CDAI ≤10 (48.5%) and the secondary endpoints (clinical remission) in terms of DAS28-ESR ≤2.6 (17.8%), SDAI ≤3.3 (8.9%), and CDAI ≤2.8 (6.9%). When TOFA was combined with MT, the discontinuation rate for the former was significantly lower (2.7%) than when TOFA was used in combination with other sDMARDs (29.4%) or alone (11.1%; p
