Genetic analysis of the relation between IL2RA/IL2RB and rheumatoid arthritis risk

We aimed to determine genetic risk factors for rheumatoid arthritis, and Chi ‐squared tests and genetic model were used to evaluate the association. Our study indicates the inherited altered genetic constitution at the IL2RA may predispose to a less destructive course of rheumatoid arthritis. AbstractBackgroundThe biological mechanisms driving disease chronicity in rheumatoid arthritis (RA) are largely unidentified. Therefore, we aimed to determine genetic risk factors for RA.MethodsIn this case –control study, which includes samples from 499 patients and 507 healthy controls, six single‐nucleotide polymorphisms (SNPs) in interleukin‐2 receptor subunit alpha (IL2RA) andIL2RB were selected. Genotyping was performed using the Agena MassARRAY platform, and the statistical analyses were performed using the chi ‐squared and Fisher's exact tests, genetic model analysis, and haplotype analysis.ResultIn the allele model, using the chi ‐squared test, the result showed that rs791588 inIL2RA was associated with a decreased RA risk (odds ratios [OR]  = 0.74, 95% confidence intervals [CI] = 0.62–0.89,p = 0.0014) after adjusting for age and gender. In the genetic model, logistic regression analyses revealed that rs791588 was associated with a decreased risk of RA under the codominant model, dominant model, recessive model, and log‐additive model. Stratification analysis revealed that two SNPs (rs791588 and rs2281089) were significantly ...

VasconcelosABSTRACTMacrophage migration inhibitory factor (MIF) is a pleiotropic cytokine that is produced by many cell types in situations of homeostasis or disease. One of its functions is to act as a proinflammatory molecule. In humans, several studies have shown that MIF levels become elevated in the serum, urine, cerebrospinal flu...

AbstractPurpose of ReviewThe purpose of this review is to discuss the literature on associations between vitamin D and periodontal disease, including its strengths and weaknesses. Future direction for continued work in this area is provided.Recent FindingsResearch in cross-sectional cohorts, surveys, and case-control studies provide support for a role of vitamin D in periodontal disease, especially using clinical indicators such as bleeding on probing and clinical attachment loss. However, these studies have a number of limitations. They cannot establish temporality of these associations. Most case-control studies have bee...

We aimed to evaluate the periodontal status in RA with and without baricitinib, a Jan...

The barrier between mind and body appears to be crumbling. Clinical practice and public perception need to catch upUnlikely as it may seem, #inflammation has become a hashtag. It seems to be everywhere suddenly, up to all sorts of tricks. Rather than simply being on our side, fighting infections and healing wounds, it turns out to have a dark side as well: the role it plays in causing us harm.It ’s now clear that inflammation is part of the problem in many, if not all, diseases of the body. And targeting immune or inflammatory causes of disease has led to a series of breakthroughs, from new treatments for rheumatoid ...

AbstractAimThe Certolizumab –Optimal Prevention of joint damage for Early Rheumatoid Arthritis (C‐OPERA) study demonstrated that in methotrexate (MTX)‐naïve early RA patients with poor prognostic factors, 1‐year certolizumab pegol (CZP) therapy added to the first year of 2‐year optimized MTX therapy brings radiograp hic and clinical benefits through 2 years even after stopping CZP. This exploratory analysis aimed to identify factors at baseline and at CZP discontinuation associated with successful CZP discontinuation.MethodsMTX ‐naïve early RA patients with poor prognostic factors entered C...

In this study, we tested the role of damp and heat environments in exacerbating RA inflammation and the anti-inflammatory effect of BHGZ, based on succinate/SUCNR1/IL-1β pathway in the adjuvant arthritis (AA) model with damp and heat environment (AA + DHE). Results showed that paw swelling and synovial pathology were significantly increased in AA rats, and these results were aggravated by stimulation in damp and heat environment. BHGZ improved AA + DHE rats' paw swelling, synovial hyperplasia, and inflammatory cell infiltration and reduced IL-1β. In addition, AA rats significantly incr...

AbstractAimsTo (1) determine the reliability and validity of the Bristol Rheumatoid Arthritis Fatigue scale (BRAF-NRS) in patients with psoriatic arthritis (PsA) and (2) examine possible clinical associations of worse fatigue in PsA.MethodsStudy phase 1: BRAF-NRS scale validation cohort. A consecutive cohort of 70 PsA patients was recruited to complete the 3-item BRAF-NRS and the 13-item Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaires, alongside disease activity assessment. All patients also completed the BRAF-NRS questionnaire, 1  day later. Study phase 2: Identifying the potential c...
