[Current treatment for spondyloarthritis: focus on netakimab. A review].

Spondyloarthritis (SpA) is a group of rheumatic diseases that includes ankylosing spondylitis (AS), psoriatic arthritis (PsA) and a number of other diseases. SpA lead to a significant social problem, since it is a common pathology that debuts mainly at a young age, significantly impairing the ability to work and the ability to social contacts of the most active part of the population. For all the main types of chronic progressive SpA, biological agents (biologics) are of great importance in patients with persistent activity despite standard treatment, especially in the case of predominantly axial involvement, since in this case it is actually the only option for effective treatment, in addition to the constant use of non-steroidal anti-inflammatory drugs (NSAIDs).

Determination of Heterogeneous Proteomic and Metabolomic Response in anti-TNF and anti-IL-6 Treatment of Patients with Rheumatoid Arthritis.

Reduction in tumor necrosis factor (αTNF) and interleukin-6 (IL-6) activities is a widely utilized strategy for the treatment of rheumatoid arthritis (RA) with a high success rate. Despite both schemes targeting the deprivation of inflammatory reactions caused by the excessive activity of cytokines, their mechanisms of action and the final output are still unequal. This was a comparative longitudinal study that lasted for 24 weeks and aimed to find the answer to why the two schemes of therapy can pass out of proportion in attitude of their efficiency.

Torque Teno Virus quantification for monitoring of immunomodulation with biologic compounds in the treatment of rheumatoid arthritis.

Objectives: RA patients who fail to respond to MTX can receive biologic dMARDs (bDMARDs). The Torque Teno Virus (TTV) is a potential novel candidate for monitoring of immunosuppression. We explore TTV in these patients and its association with clinical response to bDMARDs.

[Efficacy and safety of magnet therapy using portable device for knee osteoarthritis. 55-week double-blind study results].

Unlabelled: Instrumental physiotherapeutic treatment using portable devices is optimal for patients with rheumatic diseases due to the devices' greater accessibility. However, there are still issues concerning the efficacy of physical factors generated by portable equipment in osteoarthritis (OA), mostly due to the limited evidence.

Objective: To study the efficacy and safety of long-term use of the portable magnet therapy device ALMAG+ () in knee OA (KOA).

[Pathophysiological mechanisms of the therapeutic action of alternating electromagnetic fields in the treatment of osteoarticular pathology].

Treatment of osteoarticular pathology with an alternating electromagnetic field (AEMF) is used today as a promising, non-invasive and safe strategy of physiotherapy. It has been shown that the action of alternating electromagnetic fields on the musculoskeletal system triggers signaling cascades that effectively contribute to the restoration of bone and articular tissue. The pathophysiological mechanisms underlying the cellular and subcellular effects of stimulation by an alternating electromagnetic field during the restoration of bone and articular tissue are considered.

[Apparatus physiotherapy in the treatment of rheumatic diseases].

Unlabelled: Rheumatic diseases are a major medical and social problem. The mechanisms' variety of these diseases' development requires different approaches: the strategies of drug and non-drug therapy in modern rheumatology are designed to be complemented to each other. The most relevant treatment of rheumatic conditions is the method of pulsed magnetic fields because the sensitivity of biological tissues to them is the highest one.

[The role of rehabilitation and apparatus physiotherapy in rheumatic disease treatment strategies].

Rheumatic diseases are a serious medical and social problem. The variability of mechanisms for the development of this group of diseases requires different approaches: strategies of drug and non-medicament therapy in modern rheumatology are designed to complement each other. EULAR recommendations pay insufficient attention to the use of non-medical methods of joint disease treatment.

Evaluation of Physicians' Knowledge and Attitudes Towards Biosimilars in Russia and Issues Associated with Their Prescribing.

Physician awareness and perceptions towards biosimilars are important factors in their adoption to clinical practice. Our objectives were to assess levels of knowledge and attitudes towards biosimilars and key policies on their use among Russian physicians, define the level of interest in new information on biosimilars, and determine what evidence drives treatment decisions in Russia. Physicians with awareness of biologics across different specialties and regions of Russia completed an online survey.

Efficacy and tolerability of abatacept treatment: results of 12 months observation.

Aim: This article reports 1-year clinical outcomes of patients with rheumatoid arthritis (RA) receiving abatacept (ABA) therapy.

Materials And Methods: Patients (n=91) with high RA activity (DAS28 = 5.1 ± 1.

Association of polymorphisms of HLA-DRB1 and TNF-308 G/A with radiographic joint damage in patients with early rheumatoid arthritis with high inflammatory activity, treated according to the principle of "Treat to target" (REMARKA study).

Aim: To clarify the association between HLA-DRB1 and TNFα (-308G>A) genes polymorphism and joint destruction/further progression during 12 months of the follow-up period (FUP) in patients with early (<6 months), active, predominantly antibodies to cyclic citrullinated peptide (ACCP) and rheumatoid factor (RF)-positive rheumatoid arthritis (RA) treated according to "Treat to target" strategy.

Materials And Methods: The study included 85 patients with early RA and duration of symptoms <6 months. All patients were initially assigned to subcutaneous methotrexate (MTX) with rapid dose escalation to 20-25 mg/week.

Quantitative assessment of betamethasone dual-acting formulation in urine of patients with rheumatoid arthritis and ankylosing spondylitis after single-dose intramuscular administration and its application to long-term pharmacokinetic study.

Quantitative evaluation and assessment of pharmacokinetic parameters of Diprospan (suspension for injection 7mg/mL (2mg+5mg/mL) of betamethasone) were performed in urine samples taken from patients with rheumatoid arthritis or ankylosing spondylitis for 28days after systemic intramuscular administration in routine clinical practice in an open-comparative prospective cohort study. The maximum betamethasone concentration was reached at day 4 of the follow-up; in some cases, β-phase of elimination of the drug was appeared at day 14 or at day 21 of the follow-up. The deferred β-phase elimination was likely a consequence of the physiological characteristics of the patients or of the influence of non-steroidal agents.

Calcification of coronary arteries in early rheumatoid arthritis prior to anti-rheumatic therapy.

Accelerated coronary atherosclerosis is common in patients with rheumatoid arthritis (RA). To examine coronary artery calcification (CAC) frequency and severity, its correlation with traditional risk factors (TRF) of cardiovascular diseases (CVD) and inflammatory markers in patients with early RA prior to anti-rheumatic therapy. RA adult patients (ACR/EULAR criteria, 2010, duration ≤ 12 months, without prior administration of disease-modifying anti-rheumatic drugs, glucocorticoids) underwent 32-row scanning for CAC scoring.

Increased baseline RUNX2, caspase 3 and p21 gene expressions in the peripheral blood of disease-modifying anti-rheumatic drug-naïve rheumatoid arthritis patients are associated with improved clinical response to methotrexate therapy.

Objective: To investigate the potential of the baseline gene expression in the whole blood of disease-modifying anti-rheumatic drug-naïve rheumatoid arthritis (RA) patients for predicting the response to methotrexate (MTX) treatment.

Methods: Twenty-six control subjects and 40 RA patients were examined. Clinical, immunological and radiographic parameters were assessed before and after 24 months of follow-up.

Maintenance of remission with combination etanercept-DMARD therapy versus DMARDs alone in active rheumatoid arthritis: results of an international treat-to-target study conducted in regions with limited biologic access.

In this transglobal, randomized, double-blind, placebo-controlled, treat-to-target study, the maintenance of efficacy was compared between biologic-and biologic-free-disease-modifying antirheumatic drug (DMARD) combination regimens after low disease activity (LDA) was achieved with biologic DMARD induction therapy. Patients with moderate-to-severe rheumatoid arthritis despite methotrexate therapy received open-label etanercept 50 mg subcutaneously once weekly plus methotrexate with or without other conventional synthetic (cs) DMARDs for 24 weeks. Patients achieving LDA [disease activity score in 28 joints based on erythrocyte sedimentation rate (DAS28-ESR) <3.

EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2016 update.

Recent insights in rheumatoid arthritis (RA) necessitated updating the European League Against Rheumatism (EULAR) RA management recommendations. A large international Task Force based decisions on evidence from 3 systematic literature reviews, developing 4 overarching principles and 12 recommendations (vs 3 and 14, respectively, in 2013). The recommendations address conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) (methotrexate (MTX), leflunomide, sulfasalazine); glucocorticoids (GC); biological (b) DMARDs (tumour necrosis factor (TNF)-inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab), abatacept, rituximab, tocilizumab, clazakizumab, sarilumab and sirukumab and biosimilar (bs) DMARDs) and targeted synthetic (ts) DMARDs (Janus kinase (Jak) inhibitors tofacitinib, baricitinib).

[N-terminal pro-brain natriuretic peptide levels and diastolic dysfunction in patients with early rheumatoid arthritis before the administration of disease-modifying antirheumatic drugs].

Subjects And Methods: The investigation enrolled 74 patients with a valid RA diagnosis (the 2010 ACR/EULAR criteria), 56 (74%) women, median (Me) age, 54 years; disease duration, 7 months; seropositive for IgM rheumatoid factor (87%) and/or anti-cyclic citrullinated peptide antibodies (100%) with no history of the use of DMARDs and glucocorticosteroids. Duplex scanning and echographic findings were used to assess TRF for CVD and carotid artery atherosclerosis (CAA) in all the patients with early RA prior to therapy.

[Relationship between matrix metalloproteinase-3 levels and articular destructive changes in early and extended rheumatoid arthritis].

Aim: To estimate a relationship between matrix metalloproteinase-3 (MMP-3) levels and articular radiographic changes in early and extended rheumatoid arthritis (RA); to analyze the role of this biomarker in predicting the progression of joint destruction in RA.

Subjects And Methods: Forty-five patients with early RA and 42 with extended RA were examined. Radiography of the hands and distal feet was performed before and one year after therapy.

The Effects of Rituximab on Lipids, Arterial Stiffness and Carotid Intima-Media Thickness in Rheumatoid Arthritis.

The aim of the study was to examine lipid profiles, arterial stiffness (AS), carotid intima-media thickness (cIMT), in 55 women with RA without overt cardiovascular disease (СVD) treated with rituximab (RTX).The following parameters were recorded before and 24 weeks after RTX therapy (2 infusions of 500 or 1,000 mg RTX intravenously, fortnightly): plasma total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides, DAS 28-ESR, serum C-reactive protein (CRP), RF IgM, AS (SI - stiffness index, RI - reflection index) by digital volume pulse contour analysis (Micro Medical, UK), and common cIMT by high-resolution B-mode carotid ultrasound. Based on the European League Against Rheumatism (EULAR) criteria, patients were divided into two groups: 1) moderate/good response to RTX therapy after 24 weeks (41 patients, 75%), 2) no response to RTX therapy (14 patients, 25%).

[Left and right ventricular diastolic dysfunction in patients with early rheumatoid arthritis before prescribing disease-modifying antirheumatic therapy].

Aim: To estimate the rate of diastolic dysfunction (DD) of the left and right ventricles (LV and RV) in patients with early rheumatoid arthritis (RA) before using disease-modifying antirheumatic drugs (DMARDs) therapy and to investigate its association with traditional risk factors (TRFs) for cardiovascular diseases (CVD) and inflammatory markers.

Subjects And Methods: The investigation enrolled 74 patients with a valid diagnosis of RA, including 56 (74%) women (median age, 54 years; disease duration, 7 months); the patients who were seropositive for rheumatoid factor (RF) (87%) and/or anti-cyclic citrullinated peptide (anti-CCP) antibodies (100%) who had not been on DMARDs or glucocorticosteroids. TRFs for CVD and carotid artery atherosclerosis were assessed from duplex scanning data and echocardiography was performed in all the patients with early RA before starting the therapy.

[The clinical informativeness of detection of antibodies to citrullinated proteins under rheumatoid arthritis].

The main diagnostic laboratory markers of rheumatoid arthritis are IgM rheumatoid factor and antibodies to citrullinated proteins. The IgM rheumatoid factor is a sensitive but insufficiently specific marker of rheumatoid arthritis. The antibodies to citrullinated proteins have a higher specificity for diagnostic of rheumatoid arthritis.

[Evaluation of methotrexate effect on the acute-phase response in rheumatoid arthritis after 12-week treatment].

Unlabelled: DAS28 index calculated with regard for ESR, the number of swollen/painful joints and evaluation of the patient's condition by VAS is universally used to estimate activity of rheumatoid arthritis (RA). There is a variant of calculation using C-reactive protein (CRP) instead of ESR. Our experience indicates that ESR decreases more slowly than CRP during treatment and better reflects dynamics of patients' condition.

[Management of patients with pulmonary fibrosis].

Rheumatoid arthritis (RA) is a chronic autoimmune systemic disease. Its systemic manifestations include interstitial lung lesions (ILL). According to morphological studies and X-ray computed tomography, the incidence of RA-associated ILL is 60-70% which gives reason to consider pulmonary fibrosis (PF) to be the main form of lung pathology in this disease.

Biopharmaceuticals for rheumatic diseases in Latin America, Europe, Russia, and India: innovators, biosimilars, and intended copies.

A biosimilar is a biopharmaceutical product intended to be comparable to a previously licensed biopharmaceutical agent. The goal of such products is to increase the accessibility of biopharmaceutical therapy for rheumatoid arthritis by reducing costs. They are not like generic drugs, in that they may differ from the reference products in manufacturing, composition, and formulation.

Rheumatoid factor positivity is associated with increased joint destruction and upregulation of matrix metalloproteinase 9 and cathepsin k gene expression in the peripheral blood in rheumatoid arthritic patients treated with methotrexate.

We evaluated changes in gene expression of mTOR, p21, caspase-3, ULK1, TNF α , matrix metalloproteinase (MMP)-9, and cathepsin K in the whole blood of rheumatoid arthritic (RA) patients treated with methotrexate (MTX) in relation to their rheumatoid factor status, clinical, immunological, and radiological parameters, and therapeutic response after a 24-month follow-up. The study group consisted of 35 control subjects and 33 RA patients without previous history of MTX treatment. Gene expression was measured using real-time RT-PCR.
