Background: This study was performed to determine the mRNA expression levels of limb-bud and heart (LBH) in peripheral blood mononuclear cells (PBMCs) from patients with rheumatoid arthritis (RA), and to assess the associations of LBH rs7579944 and rs906868 polymorphisms with RA in a Chinese population. Methods: Real-time transcription-polymerase chain reaction analysis was used to determine the LBH mRNA expression in PBMCs from 53 patients with RA and 58 healthy controls, and LBH rs7579944 and rs906868 polymorphisms were genotyped in 328 RA patients and 449 healthy controls. Results: The LBH mRNA expression levels were significantly decreased in RA patients compared with healthy controls (p = 0. Read More

Background: Rheumatoid arthritis is a chronic inflammatory disease characterized by polyarthritis with progressive articular wear, immunologic abnormalities and increasing physical limitation. Surgical correction with hip replacement comes as a successful solution for patients with advanced articular destruction. Following intervention, surgical site infection (SSI), venous thromboembolism, sepsis, renal and major cardiovascular complications are among the most cited in the literature. Read More

Destructive bone diseases caused by osteolysis are increasing in incidence. They are characterized by an excessive imbalance of osteoclast formation and activation. During osteolysis, the activation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways are triggered by receptor activator of NF-κB ligand (RANKL), inflammatory factors, and oxidative stress.

Tocilizumab, an anti-interleukin-6 (IL-6) agent, is indicated as a treatment for several autoimmune or inflammatory diseases, including rheumatoid arthritis and juvenile idiopathic arthritis (JIA). IL-6 plays roles in both immune system dysregulation and inflammation, and thus efforts to extend the utility of tocilizumab in patients with autoinflammatory conditions are ongoing. Here, we survey the literature on the off-label use of tocilizumab in patients with juvenile-onset rheumatic diseases including juvenile systemic lupus erythematosus (SLE), juvenile dermatomyositis (DM), vasculitis, juvenile scleroderma, and other autoinflammatory diseases.

Rates of morbidity and mortality from cardiovascular disease are high in patients with rheumatoid arthritis (RA); however, the mechanisms and biomarkers that reflect coronary plaque vulnerability have not yet been established. We present a case of acute coronary syndrome (ACS) presumably caused by exacerbation of chronic inflammation of RA, in which an abrupt increase in serum triglyceride was seen on the day of onset of ACS but not during effort angina. This case suggests that RA patients with an abrupt increase in triglyceride need intensive care including anti-platelet and statin therapy for the prevention of coronary plaque rupture. Read More

We encountered an elderly male patient who after cardiac surgery for mitral stenosis had refractory pitting edema in both legs involving painful leg joints after a 1-month history of waxing and waning arthralgia. His family doctor had prescribed a combination of diuretics, 40 mg furosemide and 25 mg spironolactone; however, pitting edema in his lower legs persisted. He was diagnosed with worsening of congestive heart failure because of a previous cardiac surgery and was transferred to our hospital. Read More

Introduction: The objective of the study was to compare compliance and acceptability of a new auto-injector (AI) versus syringe for administration of methotrexate (MTX) in patients with rheumatoid arthritis (RA).
Methods: We conducted a randomized, open-label, parallel group study comparing AI to pre-filled syringe (PFS). Adult patients with RA (ACR/EULAR 2010) receiving MTX (orally or by injection) for at least 3 months were allocated to AI or PFS for 6 months and then were allocated to AI for 6 further months.

Inflammation, being a hallmark of many chronic diseases, including cancer, inflammatory bowel disease, rheumatoid arthritis, and chronic kidney disease, negatively affects iron homeostasis, leading to iron retention in macrophages of the mononuclear phagocyte system. Functional iron deficiency is the consequence, leading to anemia of inflammation (AI). Iron deficiency, regardless of anemia, has a detrimental impact on quality of life so that treatment is warranted. Read More

Rationale: Inflammatory bowel disease (IBD) patients manifest symptoms of disturbed gut function, such as neural sensory-motor changes. Programmed cell death-ligand 1 (PD-L1), normally present in neural tissue, exists in close apposition to the mucosal immune system and intestinal epithelium, and a bi-directional communication is known to occur at these interfaces. Somatostatin has been shown to suppress the inflammatory reaction, and has been used in several clinical trials to treat inflammatory disorders, such rheumatoid arthritis. Read More

Rationale: The mechanisms of action of MTX (methotrexate) in the treatment of RA (rheumatoid arthritis) and PsA (psoriatic arthritis) is related to its antifolic activity, due to the high affinity for enzymes that require folate cofactors as dihydrofolate reductase and to the anti-inflammatory activity derivated from the inhibition of thymidylate synthetase that leads to the over-production of adenosine.
Patient Concerns: Our patient was a 41-year-old female, affected by PsA in treatment since 2 years with low-dose methylprednisolone and low-dose subcutaneous MTX. The treatment was effective. Read More

CD84 (SLAMF5) is a member of the SLAM family of cell-surface immunoreceptors. Broadly expressed on most immune cell subsets, CD84 functions as a homophilic adhesion molecule, whose signaling can activate or inhibit leukocyte function depending on the cell type and its stage of activation or differentiation. CD84-mediated signaling regulates diverse immunological processes, including T cell cytokine secretion, natural killer cell cytotoxicity, monocyte activation, autophagy, cognate T:B interactions, and B cell tolerance at the germinal center checkpoint.

Activins are dimeric glycoproteins belonging to the transforming growth factor beta superfamily and resulting from the assembly of two beta subunits, which may also be combined with alpha subunits to form inhibins. Activins were discovered in 1986 following the isolation of inhibins from porcine follicular fluid, and were characterized as ovarian hormones that stimulate follicle stimulating hormone (FSH) release by the pituitary gland. In particular, activin A was shown to be the isoform of greater physiological importance in humans. Read More

IgM and IgA autoantibodies binding to IgG are called rheumatoid factors (RFs) and occur with high frequency in rheumatoid arthritis (RA) and with lower frequency in other autoimmune diseases. RFs have diagnostic and prognostic value in RA, but they also have a high potential to cause false positive reactions in other immunoassays, especially sandwich assays. For these reasons it is imperative to be able to measure RFs in serum samples from patients suspected of RA or other autoimmune diseases and in serum samples to be analyzed by sandwich immunoassay for various clinical parameters.
