In patients who require a permanent central venous catheter (PCVC), the usual aim is to put the catheter tip at the superior vena cava and right atrium (SVC-RA) junction. However, there is no study regarding how to guide the positioning of the catheter tip when the SVC-RA junction cannot be ...

Osteoarthritis (OA) is a disabling condition in which multiple initiating events or conditions (heritable and nonheritable) result in eventual loss of articular cartilage. However, the etiology of OA remains poorly understood, and diagnosis of early disease is difficult due to the lack of specific identifiers. Recent literature suggests that a ...

We previously showed that renal artery stenosis (RAS) was commonly found in patients with cardiovascular disease (CVD) such as myocardial infarction, stroke, or abdominal aneurysm. The aim of the present study was to evaluate the incidence and risk factors for RAS in patients with severe carotid artery stenosis (CAS) considered ...

The macrophage inhibitory factor (MIF) is a cytokine that has been implicated in several inflammatory and autoimmune diseases, including rheumatoid arthritis, systemic lupus, glomerulonephritis, and multiple sclerosis. In rheumatoid arthritis (RA), results ranging from lack of association of MIF polymorphisms with RA, to involvement in either severity or susceptibility to ...

Advanced glycation endproducts (AGEs) are the products of non-enzymatic glycation and oxidation of proteins and lipids. Low-turnover tissues such as articular cartilage seem to be susceptible to the accumulation of AGEs, which might lead to cartilage degradation. Recently, a non-invasive method for measuring skin AGE accumulation was developed by using ...

The mean age of rheumatoid arthritis (RA) onset is around 50 years as reported in several clinical trials involving Caucasian patients. However, clinical observations suggest that Mexican RA patients' disease is initiated at a younger age. The objective of the study was to assess whether the age of onset of ...

OBJECTIVE: The etiopathogenesis of rheumatoid arthritis (RA) is not fully known; vitamin D has been shown to have immunomodulatory effects and could be implicated in it.

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) frequently cause gastrointestinal (GI) ulcers and complications of ulcers. In 1997 in Amsterdam, the incidence of symptomatic GI events was 2.1% (95% CI 1.0-3.1) in patients with rheumatoid arthritis (RA). We conducted a new prospective, observational study on the symptomatic GI events in our outpatient ...

OBJECTIVE: Mannan-binding lectin (MBL) is present in serum and synovial fluid; its levels vary widely, and the variations are strongly associated with polymorphisms in the MBL2 gene. Studies have compared MBL in patients with rheumatoid arthritis (RA) and in unrelated controls, but the findings have been contradictory. In the first ...

Osteoprotegerin (OPG), a soluble decoy receptor for receptor activator of nuclear factor kappaB ligand, is implicated in the pathogenesis of atherosclerosis. Patients with rheumatoid arthritis (RA) have inflammation and increased atherosclerosis. We examined the hypothesis that OPG concentrations are increased in patients with RA and are associated with coronary-artery atherosclerosis. ...

OBJECTIVES: The receptor for advanced glycation end products (RAGE) is expressed by many cells in joints of rheumatoid arthritis (RA) patients and interacts with a variety of pro-inflammatory ligands that are enriched in inflamed joint. The RAGE-ligand interaction leads to a sustained inflammatory response. Also, secreted form of the receptor, ...

OBJECTIVE: Rheumatoid arthritis (RA) patients have an increased risk of developing cardiovascular diseases (CVD).

The aims of this study were to compare BMD levels and frequency of osteoporosis between female patients with HOA, rheumatoid arthritis (RA) and ...

OBJECTIVE: Anti-cyclic citrullinated peptide (anti-CCP) antibodies are rheumatoid arthritis (RA)-specific serologic markers. RA susceptibility has been associated with HLA-DRB1 shared epitope (SE) alleles and single-nucleotide polymorphism (SNP) haplotypes in the peptidyl arginine deiminase 4 gene (PADI4). This study was undertaken to determine whether anti-CCP levels are associated with PADI4 haplotypes ...

METHODS: Patients with previously undiagnosed synovitis in at least one peripheral joint or signs of inflammation in sacroiliac, glenohumeral or hip ...

OBJECTIVE: Glucocorticoids (GCs) are among the most frequently used drugs for the treatment of rheumatoid arthritis (RA). Unfortunately, up to 30% of patients with RA fail to respond to the treatment. We investigated the hypothesis that patients with RA who did not respond to GC treatment have steroid-resistant peripheral blood ...

The Patient Perspective Workshop at OMERACT 8 considered evidence for the importance of fatigue to patients with rheumatoid arthritis (RA) and whether measurement of fatigue meets the requirements of the OMERACT filter. The workshop participants included 20 patients from 10 countries and 60 other OMERACT participants. Introductory papers and detailed ...

METHODS: A self-report questionnaire was completed ...

Rheumatoid arthritis (RA) is the most common inflammatory joint disease. Even though, physiopathology of rheumatoid arthritis remains unclear, the presence of circulating immune complexes and rheumatoid factors had led to the use of plasma exchange (PE). Even though PE procedures have evolved over the last decades, their indications and use ...

This study was performed to investigate whether synovial proliferation (SP) differentially affects hypoxia in the joint cavities of rheumatoid arthritis (RA) and osteoarthritis (OA) patients. Thirty RA and 42 OA patients who underwent synovitis assessment were classified into two groups based on the presence or absence of SP, as revealed ...
