OBJECTIVES: Rheumatic diseases such as osteoarthritis and rheumatoid arthritis constitute the most frequent pathological states leading to the development of foot deformities, which reduce quality of life and cause disability. The aim of the present study was to compare the results of plantoconturographic examinations, obtained by means of a computer podoscope, in osteoarthritis and rheumatoid arthritis patients. Special attention was paid to the differences in the values of each parameter determining the level of foot function...

Osteoporosis and fractures are common and invalidating consequences of chronic glucorticoid (GC) treatment. Reliable information regarding the epidemiology of GC induced osteoporosis (GIOP) comes exclusively from the placebo group of randomized clinical trials while observational studies are generally lacking data on the real prevalence of vertebral fractures, GC dosage and primary diagnosis. The objective of this study was to evaluate the prevalence and incidence of osteoporotic fractures and to identify their major determinants (primary disease, GC dosage, bone mineral density, risk factors, specific treatment for GIOP) in a large cohort of consecutive patients aged >21 years, on chronic treatment with GC (≥5 mg prednisone - PN - equivalent) and attending rheumatology centers located all over Italy...

Early diagnosis and immediately started appropriate treatment are mandatory for the prevention of radiographic progression, functional disability and unfavourable disease outcome in rheumatoid arthritis (RA). The current classification criteria for RA include two different types of biomarkers representing inflammatory processes, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) or immune processes including autoantibodies, such as rheumatoid factor (RF) and antibodies against citrullinated proteins (ACPA)...

Neutrophils are the most abundant WBCs and have an essential role in the clearance of pathogens. Tight regulation of neutrophil numbers and their recruitment to sites of inflammation is critical in maintaining a balanced immune response. In various inflammatory conditions, such as rheumatoid arthritis, vasculitis, cystic fibrosis, and inflammatory bowel disease, increased serum G-CSF correlates with neutrophilia and enhanced neutrophil infiltration into inflamed tissues. We describe a fully human therapeutic anti-G-CSFR antibody (CSL324) that is safe and well tolerated when administered via i...

Traditional and biologic disease-modifying antirheumatic drugs (DMARDs) are effective medications for the management of rheumatoid arthritis (RA). However, the effects of these medications on immune function raises concern that they may increase long-term cancer risk. The baseline risk for some cancers appears to differ in patients with RA compared to the general population, with the former having an increased risk of lymphoma, lung cancer and renal cancer, but a decreased risk of colorectal and breast cancer...

Maintenance of self-tolerance of auto-reactive lymphocytes is a fundamental mechanism to prevent the onset of autoimmune diseases. Deciphering the mechanisms involved in the deregulations leading to tolerance disruption and autoimmunity is still a major area of interest to identify new therapeutic targets and options. Ca(2+) signaling plays a major role in B cell normal development and is therefore finely tuned by B cell receptor (BCR)-dependent and independent pathways. Developmental changes in the characteristics of BCR-dependent Ca(2+) signals as well as the modulation of basal intracellular concentration ([Ca(2+)]i) contribute strongly to self-tolerance maintaining mechanisms responsible for the physical or functional elimination of autoreactive B cells such as clonal deletion, receptor editing, and anergy...

Cytotoxic T-lymphocyte antigen 4 (CTLA-4)-mediated regulation of already tolerized autoreactive T cells is critical for understanding autoimmune responses. While defects in CTLA-4 contribute to abnormal FOXP3(+) regulatory T cell (Treg) function in rheumatoid arthritis (RA) its role in autoreactive T cells remains elusive. We studied immunity towards the dominant collagen type-II (CII) T cell epitope in collagen-induced arthritis (CIA) both in the heterologous setting and in the autologous setting where CII is mutated at position E266D in mouse cartilage...

New evidence of the interactions between the immune system and bone has accumulated in bone diseases, including osteoporosis, periodontitis and rheumatoid arthritis. A marked imbalance between bone resorption and formation is central to the onset of pathological bone loss. Osteoimmunology has revealed that the immune system, including T cells, B cells and inflammatory cytokines, is a key regulator of both osteoclasts and osteoblasts. Th1 cells, which differentiate from CD4+T cells, are thought to play a major function during bone loss...

During budding, lentiviral particles (LVP) incorporate cell membrane proteins in the viral envelope. We explored the possibility of harnessing this process to generate LVP-expressing membrane proteins of therapeutic interest and studied the potential of these tools to treat different pathologies. Fas-mediated apoptosis is central to the maintenance of T cell homeostasis and prevention of autoimmune processes. We prepared LVP that express murine FasL on their surface. Our data indicate that mFasL-bearing LVP induce caspase 3 and 9 processing, cytochrome C release, and significantly more cell death than control LVP in vitro...

OBJECTIVE: In systemic lupus erythematosus (SLE), cardiovascular disease (CVD) is an important cause of long-term morbidity, which could be affected by statin use. Here we review the evidence for the use of statins for the prevention of CVD in patients with SLE. METHODS: The PubMed database was searched using a query combining SLE and statins. RESULTS: The search yielded nine relevant clinical studies. Seven studies reported on radiological findings that correlate with atherosclerosis and mainly revealed that statin treatment resulted in a slight decrease in progression of carotid intima-media thickness and an increase in flow-mediated vasodilatation...

BACKGROUND: In low level laser therapy (LLLT) low wattage lasers are used to irradiate the affected skin areas, joints, nerves, muscles and tendons without any sensation or thermal damage. Although the exact mechanism of its effect is still unknown, it seems beyond dispute that LLLT induces a variety of stimulating processes at the cellular level affecting cell repair mechanisms, the vascular system and lymphatic system. LLLT has been popular among orthopaedic practitioners for many years, whereas university medicine has remained rather sceptical about it...

T-cell activation RhoGTPase-activating protein (TAGAP) is a GTPase-activating protein specific for RhoA that is exclusively expressed in activated T cells. Genome-wide association studies and metagenome SNPs analyses have indicated that TAGAP is associated with the pathogenesis of multiple autoimmune diseases, including psoriasis, rheumatoid arthritis, Crohn's disease, celiac disease and multiple sclerosis. However, the precise function of TAGAP remains unclear. Because TH17 cells contribute to TAGAP-associated autoimmune diseases, we hypothesized that TAGAP plays key roles in the differentiation and/or function of TH17 cells...

The etiopathogenesis of rheumatoid arthritis (RA) is partially understood. Genetic, environmental, and hormonal factors and their interactions are considered to play an important role on disease development. The relative contribution of environmental factors to RA development is probably larger than previously thought. The aim of this review is to appraise robust evidence about the role of environmental and hormonal risk factors for RA. We will discuss inhaled pollutants, nutritional habits, infectious, hormonal, and reproductive factors...

Histamine H4 receptor (H4R) has immune-modulatory and chemotaxic effects in various immune cells. This study aimed to determine the osteoclastogenic role of H4R in rheumatoid arthritis (RA). The concentration of histamine in synovial fluid (SF) and sera in patients with RA was measured using ELISA. After RA SF and peripheral blood (PB) CD14+ monocytes were treated with histamine, IL-17, IL-21 and IL-22, and a H4R antagonist (JNJ7777120), the gene expression H4R and RANKL was determined by real-time PCR. Osteoclastogenesis was assessed by counting TRAP-positive multinucleated cells in PB CD14+ monocytes cultured with histamine, Th17 cytokines and JNJ7777120...

Increasing evidence has suggested that systemic inflammation along with local brain inflammation can play a significant role in Alzheimer's disease (AD) pathogenesis. Identifying key molecules that regulate the crosstalk between the immune and the central nervous system can provide potential therapeutic targets. TNF-α is a pro-inflammatory cytokine implicated in the pathogenesis of systemic inflammatory and neurodegenerative diseases such as rheumatoid arthritis (RA) and AD. Recent studies have reported that anti-TNF-α therapy or RA itself can modulate AD pathology, although the underlying mechanism is unclear...

Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. The prerequisites for reducing the risk of cardiovascular disease are adequate levels of knowledge and being aware of the risk. In this study, the levels of knowledge about cardiovascular disease among patients with rheumatoid arthritis and the perception were evaluated in relation to their actual 10-year risk of cardiovascular disease. This cross-sectional study of 200 patients with rheumatoid arthritis was conducted in a university-affiliated hospital in South Korea...

OBJECTIVE: The relationship between arthroplasty and long-term opioid use in patients with knee or hip osteoarthritis is not well studied. We examined the prevalence, patterns and predictors of persistent opioid use after hip or knee arthroplasty. METHOD: Using claims data (2004-2013) from a US commercial health plan, we identified adults who underwent hip or knee arthroplasty and filled ≥1 opioid prescription within 30 days after the surgery. We defined persistent opioid users as patients who filled ≥1 opioid prescription every month during the 1-year postoperative period based on group-based trajectory models...
