Tenascin-C (TN-C) levels are elevated in the synovial tissue and fluid, as well as cartilage of rheumatoid arthritis (RA) patients. In addition, the presence of TN-C fragments has also been documented in arthritic cartilage. We have previously shown that a single chain variable fragment antibody (TN64), directed against the fibronectin type III repeats 1-5 (TNfnIII 1-5) of TN-C, effectively inhibits fibrotic pathology. Given that fibrosis results from chronic inflammation, and the fact that increased levels of TN-C in the synovial fluid of patients with RA contributes to synovial inflammation and joint destruction, we aimed to investigate the role of TNfnIII 1-5 region of TN-C in RA pathogenesis...

Objective: The aim of the present study is to report on the reduction of edema of lymphedematous arms just by treating the lower limbs. Methods: A 16-year-old girl reported that she has started having right lower limb edema at the age of three. At age 13, she performed a lymphoscintigraphy that confirmed the diagnosis of primary lymphedema of the four limbs. Recently she sought treatment at the Clínica Godoy in São Jose do Rio Preto where she was submitted to intensive treatment for eight hours per day for five days using manual (Godoy & Godoy technique) and mechanical lymphatic therapy (RA Godoy® ) of the lower limbs, cervical lymphatic therapy (cervical stimulation), and the continuous use of a grosgrain stocking...

The immune system plays an important role in glaucomatous neurodegeneration. Retinal microglial reactivation associated with ganglion cell loss could reportedly contribute to the glaucoma progression. Recently we have described signs of microglia activation both in contralateral and ocular hypertension (OHT) eyes involving all retinal layers 15 days after OHT laser induction in mice. However, no works available have analyzed the microglial activation at earliest time points after OHT induction (24 h) in this experimental model...

Patient global assessment (PGA) is included in almost all rheumatoid arthritis (RA) composite disease activity indices and definitions of remission. However, different PGA formulations exist and are used interchangeably in research and clinical practice. We investigated how five different PGA formulations used in four disease indices affect the remission rates. This was an ancillary analysis of data from a cross-sectional study in patients with RA. The data comprised the following: 28-joint counts, C-reactive protein, and five PGA formulations...

Rheumatoid arthritis (RA) patients may suffer from comorbid neuropsychiatric symptoms including mild cognitive impairment (MCI). Although comorbidity of MCI is common, there are currently no validated plasma biomarkers to aid MCI diagnosis. This study screened plasma from patients with RA with and without comorbid MCI to identify potential biomarkers useful in the differential diagnosis of comorbid MCI. Plasma samples were collected from patients with RA without comorbid MCI, with comorbid MCI, and from healthy controls...

BACKGROUND AND AIMS: Cardiovascular (CV) morbidity is increased in inflammatory joint diseases (IJD), as rheumatoid (RA) and psoriatic arthritis (PsA). Whereas increased prevalence of subclinical atherosclerosis has been reported in these conditions, whether an early myocardial functionality is also impaired remains unknown. The aim of this study was to evaluate the myocardial functionality by speckle-tracking echocardiography (STE) in recent onset RA and PsA patients and its potential associations with the levels of circulating CD34 +  cells, vitamin D, and with disease activity...

Cardiovascular disease associated with obesity and autoimmunity is the leading cause of death in these populations and significant residual risk remains despite current treatment approaches. Obesity, type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) are linked to chronic inflammation, and subjects with these disorders have characteristic shifts in their gut microbiome composition. Recent data suggest that alterations in gut microbial and metabolic composition may be responsible, in part, for induction of chronic inflammation, thus promoting cardiovascular disease...

Cigarette smoking (CS) is a well-established risk factor for cardiovascular disease (CVD). Endothelial dysfunction (ED) with loss of nitric oxide (NO) production is a central mechanism leading to the advent of CVD. Despite many prior studies of this major health problem, the exact mechanism by which CS induces ED is not well understood. This study examines the mechanism by which CS induces ED with altered endothelial NO synthase (eNOS) function in aortic endothelial cells (AECs). Exposure of AECs to cigarette smoke extract (CSE) resulted in a marked decrease in NO production with concomitant increase in superoxide (O2 ...

Reactive oxygen species (ROS) are byproducts of oxygen metabolism best known for their damaging potential, but recent evidence has exposed their role as secondary messengers, which regulate cell function through redox-activatable signaling systems. In immune cells, specifically in T cells, redox-sensitive signaling pathways have been implicated in controlling several functional domains; including cell cycle progression, T effector cell differentiation, tissue invasion and inflammatory behavior. T cells from patients with the autoimmune disease rheumatoid arthritis (RA) have emerged as a valuable model system to examine the functional impact of ROS on T cell function...

Pollution has long been incriminated in many cardiovascular and respiratory diseases. More recently, studies evaluated the potential role for particulate pollutants in autoimmune diseases, including rheumatoid arthritis (RA). The incidence of RA was found to be higher in urban areas. Living near air pollution emitters was associated with higher risks of developing RA and of producing RA-specific autoantibodies. Nevertheless, no strong epidemiological evidence exists to link one or more specific air pollution particles to RA...
