OBJECTIVE: Rheumatoid arthritis is a progressive inflammatory disease with multiple dysfunctional intracellular signaling pathways that necessitate new approaches for its management. Hence, the study aimed to inspect the ability of the combination therapy of metformin and omega-3 to modulate different signaling pathways and micro RNAs such as (miR-155, miR-146a and miR-34) as new targets in order to mitigate adjuvant-induced arthritis and compare their effect to that of methotrexate. METHODS: Fourteen days post adjuvant injection, Sprague-Dawley rats were treated orally with metformin (200 mg/kg/day) and/or omega-3 (300 mg/kg/day) or intraperitoneally with methotrexate (2 mg/kg/week) for 4 weeks...

This study was aimed at generating and investigating the efficacy of a novel monoclonal bispecific antibody (BsAb) for the combined inhibition of tumor necrosis factor-α (TNF-α) and CXCL10 as a treatment option for rheumatoid arthritis (RA). A novel BsAb targeting TNF-α and CXCL10 was generated by conjugating a single-chain variable fragment (scFv) of the anti-CXCL10 monoclonal antibody to the Fc region of adalimumab (ADA). The effects of the BsAb on the inflammatory response in the in vitro and in vivo development of arthritis and joint destruction were evaluated in human TNF transgenic (hTNF-Tg) mice, and K/BxN serum transfer arthritis models...

Evidence suggests that uncontrolled immune system responses and their components play a significant role in developing rheumatoid arthritis (RA), which is considered an autoimmune disease (AD). Among immune system mediators, cytokines and chemokines are involved in numerous physiological and pathological processes. CCL2 or monocyte chemoattractant protein-1 (MCP-1) is known as a CC chemokine that can induce the locomotion and recruitment of monocytes and macrophages to the site of injury. When CCL2 binds to its receptors, the most important of which is CCR2, various signaling pathways are triggered, eventually leading to various immunological events such as inflammation...

OBJECTIVES: Rheumatoid arthritis (RA) patients show an earlier circadian rhythm (i.e. serum melatonin peaks earlier during the night, indicating an earlier timing of the internal circadian pacemaker). In the current study, we examined whether the chronotype, which is influenced by the circadian rhythm, is also earlier. In addition, we explored whether chronotype is related to disease activity and patient-reported outcomes. METHODS: The chronotype (Munich Chronotype Questionnaire) of patients with RA (n = 121; mean age 60 years, 73% female) was compared with that of subjects from the general population (norm group; n = 1695) with a one-sample t test...

OBJECTIVE: The aim of this study was to develop a patient-centered quality measurement framework to address a predefined vision statement and 7 strategic objectives for rheumatoid arthritis (RA) care that was developed in prior qualitative work with arthritis stakeholders. METHODS: One hundred forty-seven RA-related performance measures (PMs) were identified from a systematic review. A candidate list of 26 PMs meeting predefined criteria and addressing the strategic objectives previously defined was then assessed during a 3-round (R) modified Delphi...

OBJECTIVE: To examine the relationship between the use of Hydroxychloroquine (HCQ) and risk of developing Heart Failure (HF) in Rheumatoid Arthritis (RA). METHODS: In this nested case-control study, cases were Olmsted county, Minnesota residents with incident RA (based on 1987 ACR criteria) from 1980-2013 who developed HF after RA incidence. Each case was matched on year of birth, sex and year of RA incidence with an RA control who did not develop HF. Data on HCQ use including start and stop dates and dose changes was reviewed, and used to calculate HCQ duration and cumulative dose...

OBJECTIVE: Both erectile dysfunction (ED) and rheumatoid arthritis (RA) are associated with increased cardiovascular risk. It is unknown if these diagnoses are associated or if their combination confers additional cardiovascular risk. We aim to define the incidence of ED in RA, and determine if ED correlates with increased cardiovascular risk in RA. METHODS: Medical information concerning RA, ED and cardiovascular diagnoses for men with RA (n=260) diagnosed in Olmsted county, Minnesota and age-matched male comparators was extracted from a comprehensive medical record system...

OBJECTIVES: Lack of effective biomarkers in anti-citrullinated protein antibody (ACPA)-negative rheumatoid arthritis (RA) impedes early diagnosis and treatment. This study aimed to identify novel autoantibodies in RA and verify their diagnostic values in ACPA-negative RA based on protein microarray technology. METHODS: A total of 1011 sera from 559 RA (276 ACPA-positive and 283 ACPA-negative), 239 disease controls (DCs) and 213 healthy controls (HCs) were collected and sampled on two sequential microarrays and ELISA and western blot (WB) detection, for novel autoantibodies discovery, validation and verification, respectively...

The complement system (CS) includes more than 50 proteins and its main function is to recognize and protect against foreign or damaged molecular components. Other homeostatic functions of CS are the elimination of apoptotic debris, neurological development, and the control of adaptive immune responses. Pathological activation plays prominent roles in the pathogenesis of most autoimmune diseases such as systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis, dermatomyositis, and ANCA-associated vasculitis...

Autoimmune diseases, including psoriasis, systemic lupus erythematosus (SLE), and rheumatic arthritis (RA), are caused by a combination of environmental and genetic factors that lead to overactivation of immune cells and chronic inflammation. Since oxidative stress is a common feature of these diseases, which activates leukocytes to intensify inflammation, antioxidants could reduce the severity of these diseases. In addition to activating leukocytes, oxidative stress increases the production of lipid mediators, notably of endocannabinoids and eicosanoids, which are products of enzymatic lipid metabolism that act through specific receptors...

The aim of this study was to investigate the changes in and clinical significance of circular RNAs (circRNAs) expression related to immunity and inflammation in patients with rheumatoid arthritis (RA). We analyzed the circRNAs related to immunity and inflammation in peripheral blood mononuclear cells (PBMCs) from three RA patients and three healthy controls using high-throughput sequencing and bioinformatics analysis. Subsequently, four differentially expressed circRNAs were verified by reverse transcriptase quantitative polymerase chain reaction (RT-qPCR)...

The downregulation of miR-30a-3p has been reported in rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS); however, it is poorly understood its possible involvement and the underlying mechanism. The effects of miR-30a-3p overexpression on the proliferation and apoptosis as well as oxidative stress injury were evaluated in rats RA-FLS. The targeting relationship between miR-30a-3p and Kelch-like erythroid cell-derived protein with CNC homology (ECH)-associated protein 1 (Keap1) or cullin3 (cul3) was assessed by luciferase reporter assays...

Rheumatoid arthritis (RA) is an autoimmune disease that occurs in approximately 1.0% of the general population. In RA patients, physical disability and joint damage are the major prognostic factors, which are associated with a reduction in the quality of life and early mortality. At present, the exact molecular mechanism of RA remains elusive. Long noncoding RNAs (lncRNAs) have been revealed to play a regulatory role in the pathogenesis of RA. To reveal the function of lncRNAs in rheumatoid arthritis, lncRNAS56464...

OBJECTIVE: RA is associated with higher risk of cardiovascular (CV) disease. Ongoing systemic inflammation is presumed to accelerate atherosclerosis by increasing inflammation in the arterial wall. However, evidence supporting this hypothesis is limited. We aimed to investigate arterial wall inflammation in RA vs OA, and its association with markers of inflammation and CV risk factors. METHODS: 18-fluorodeoxyglucose PET combined with CT (18F-FDG-PET/CT) was performed in RA (n = 61) and OA (n = 28) to investigate inflammatory activity in the wall of large arteries...
