“…In confirmed RA, 14-3-3η levels decrease with treatment response (2) and those changes are associated with clinical and radiographic outcomes, including the prediction of joint damage progression in patients who have achieved clinical remission. Upadacitinib (UPA), an oral JAK1-selective inhibitor, demonstrated significant and clinically meaningful improvements in RA vs. methotrexate (MTX) in the SELECT-EARLY phase 3 study (3). Objectives: To determine the impact of treatment with UPA monotherapy 15 mg QD on the levels of plasma 14-3-3η and to explore its relationship with clinical measures in early MTX-naïve RA patients.…”

Background:Cytokines stimulate the inflammatory response in the synovial membrane with rheumatoid arthritis (RA), initiate apoptosis of chondrocytes, activation of osteoclasts. The progression of comorbid diseases is also associated with the influence of cytokines. At the same time, anti-inflammatory cytokines are produced in various tissues. Their role in the pathogenesis of RA and its complications is ambiguous.Adiponectin (A) and Fetuin A (FA) are classified as negative acute phase proteins. Their concentration decreases with an increase in the level of pro-inflammatory cytokines: TNF-α, IL-1 and IL-6. Molecules A and FA, regardless of various factors and from each other, have similar effects in relation to pro-inflammatory cytokines, lipid and carbohydrate metabolism.Visfatin (V) and Nesfatin-1 (N-1) are pro-inflammatory adipokines. B is produced by cells of the mononuclear phagocytic system and connective tissue. N-1 - is produced by the cells of the intermediate and medulla oblongata and by the cells of the gastric mucosa.Objectives:to study the correlation of B, H-1, A and FA with the severity of inflammation in RAMethods:60 patients with RA and 30 healthy individuals were examined. The level of cytokines was determined by an indirect enzyme-linked immunosorbent assay using commercial test systems (Bio Vendor, cat No. RD195023100, Bio Vendor Human Fetuin-A, RaiBiotech, cat No. EIA-VIS-1, RaiBiotech, cat No. EIA-NESF). All patients underwent a full examination. Diagnosed with 2010 EULAR / ACR recommendations.Results:A decreased level of A (less than 0.8 μg/ml) was detected in 15 patients (25%), F-A (less than 653.55 μg/ml) in 16 (27%), a high level of V (more than 39 ng/ml) - in 55 (91%), N-1 (more than 37.95 ng/ml) - in 36 (60%), which is significantly more often than in healthy individuals. No significant difference in the levels of determined adipokines was found depending on the gender and body weight of patients with RA. The level of cytokines in RA is associated with high activity according to DAS 28, positivity by Anti-CCP, extraarticular manifestations of RA. The greatest correlation with extraarticular manifestations is with cutaneous and cerebral vasculitis. The levels of FA and N-1 also correlated with more pronounced radiological changes (X-ray stage III). FA circulating inhibitor of ectopic calcification. N-1 level is positively correlated with systolic blood pressure.Conclusion:A low level of A and FA, a high level of V and N-1 is characteristic of RA with the presence of high activity and positivity in the RF and Anti-CCP. An increased level of B is determined by more than 90% of patients, which indicates its high pro-inflammatory activity. The level of F and N-1 is also associated with the degree of damage to bone tissue (stage III, a lot of erosion). A positive correlation of level V and N-1, negative A and FA with the severity of inflammation in RA confirms the involvement of these proteins in the pathogenesis. A high level of A and V increases the risk of developing cardiovascular diseases and their complications, the effect of N-1 and FA is being studied. The effect of cytokines on osteoclasts and osteoblasts in RA is ambiguousReferences:[1]Visfatin and Rheumatoid Arthritis: Pathogenetic Implications and Clinical Utility. Polyakova Y.
