Antibodies to proteins/peptides containing citrulline are hallmarks of Rheumatoid Arthritis (RA). These antibodies are strongly associated with the expression of the Shared Epitope (SE). RA patients also generate antibodies to homocitrulline-containing proteins/peptides (also referred to as anti-carbamylated protein antibodies (Anti-CarP)). This study was undertaken to investigate the relationship between homocitrulline and citrulline immune responses using an established mouse model of RA: DR4-transgenic (DR4tg) mice that express the human SE...

BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic synovitis, cartilage degradation and bone deformities. Synovitis is the term for inflammation of the synovial membrane, an early stage of RA. The pathogenesis of the disease occurs through cytokine induction. The major cytokine that increases the severity of RA is TNF-α. Thus, inhibition of the TNF-α cascade is an effective way to diminish the progression of the disease. We are interested in investigating the difference between primary human synovial fibroblast (hSF) cells and SW982 as synovitis models induced by TNF-α and in monitoring their responses to sesamin as an anti-inflammatory phytochemical...

Introduction Osteoarthritis (OA), a chronic, debilitating and degenerative disease of the joints, is the most common form of arthritis. The seriousness of this prevalent and chronic disease is often overlooked. Disease modifying OA drug development is hindered by the lack of soluble biomarkers to detect OA early. The objective of OA biomarker research is to identify early OA prior to the appearance of radiographic signs and the development of pain. Areas covered This review has focused on extracellular genomic material that could serve as biomarkers of OA...

Jejunoileal bypass (JIB) was developed as a surgical treatment for morbid obesity in the early 1950s. However, this procedure is now known to be associated with multiple metabolic complications and has subsequently been abandoned as a viable bariatric procedure. Some of these known complications include renal stone formation, liver failure, migratory arthritis, fat-soluble deficiencies, blind-loop syndrome and severe diarrhea. Additionally, there have been animal models suggesting colon dysplasia after JIB...

Individuals with rheumatoid arthritis (RA) benefit from early diagnosis and initiation of therapy. There can be delays in both due to diagnostic uncertainties. Imaging modalities, including magnetic resonance imaging (MRI), can detect inflammation earlier than clinical examination alone in early RA patients. Furthermore, the predictive role of MRI for the future development of RA has recently been explored in 'at-risk' individuals. This review details the use of MRI in early and undifferentiated arthritis and summarises the studies to date in individuals at risk of RA...

Early diagnosis and treatment improves outcomes for patients with rheumatoid arthritis (RA). Studies have shown that musculoskeletal ultrasound is more sensitive than clinical examination in identifying synovitis. This review aims to address the role of ultrasound in identifying (1) patients with early inflammatory arthritis (IA) at risk of progression to RA and (2) those without clinical synovitis at risk of progression to early IA and therefore early RA.

Autoimmunity precedes inflammation in patients with rheumatoid arthritis (RA), opening the possibility to search for early changes in the tissue preceding the onset of systemic inflammation. Autoantibodies are important and early drivers of bone damage in RA. This article summarizes current evidence for the role of RA-related autoantibodies in mediating bone loss. Rheumatoid factor (RF) and antibodies recognizing modified (citrullinated) proteins have been used as diagnostic markers for RA over many years. Their role as pathogenic players, however, has long been unrecognized...

Vijay Joshua, Katerini Chatzidionisyou, Anca I Catrina
Antibody-positive (seropositive) rheumatoid arthritis (RA) is a complex multiphasic disease developing in genetically susceptible individuals following environmental challenges (such as smoking). RA-associated autoantibodies can develop several years before any clinical signs of joint inflammation, suggesting that triggering of this autoimmunity occurs outside the joints. Epidemiological, clinical, and molecular studies in seropositive individuals at risk for developing RA as well as in early untreated RA suggest a potential role for mucosal sites (especially lung mucosa) as RA-associated autoimmunity trigger sites...

Neelakshi R Jog, Judith A James
Autoimmune connective tissue diseases are clinically variable, making biomarkers desirable for assessing future disease risk, supporting early and accurate diagnosis, monitoring disease activity and progression, selecting therapeutics, and assessing treatment response. Because of their correlations with specific clinical characteristics and often with disease progression, autoantibodies and other soluble mediators are considered potential biomarkers. Additional biomarkers might reflect downstream pathologic processes or appear because of ongoing inflammation and damage...

BACKGROUND: Uncontrolled active rheumatoid arthritis can lead to increasing disability and reduced quality of life over time. 'Treating to target' has been shown to be effective in active established disease and also in early disease. However, there is a lack of nationally agreed treatment protocols for patients with established rheumatoid arthritis who have intermediate disease activity. This trial is designed to investigate whether intensive management of disease leads to a greater number of remissions at 12 months...

BACKGROUND: Psoriatic arthritis (PsA) is a chronic inflammatory disease associated with psoriasis (PsO). Early diagnosis and prompt therapeutic intervention are crucial for limiting PsA progression and prevention of disability. Dermatologists are in a privileged position to detect early PsA. The management of patients with PsA in the dermatology setting is widely variable. OBJECTIVE: To provide practical recommendations for the management of patients with PsA in the dermatology setting including early diagnosis and treatment...

Severity of S. aureus septic arthritis is correlated to prolonged inflammation by inflammatory cytokines like TNF-α, IL-1β, and IL-6 even after successful elimination of bacteria. Role of TNF-α via TNFR2 is not well established in this aspect. IFN-γ induces TNF-α release from the macrophages augmenting the inflammatory arthritis. IL-10 modulates the levels of pro-inflammatory cytokines promoting resolution of inflammation. TNF-α-TNFR2 signaling upregulates both of these cytokines. Higher level of MMP-2 induction by inflammatory cytokines during arthritis promotes tissue destruction...

PURPOSE OF REVIEW: Rheumatoid arthritis is a systemic disease of evolving immune dysregulation that culminates in joint destruction and disability. The principle by which pro-inflammatory cytokines may be therapeutically targeted to abrogate disease is well established, but has yet to translate into reliable cures for patients. Emerging insights into cytokine-mediated pathobiology during rheumatoid arthritis development are reviewed, and their implications for future treatment strategies considered...

BACKGROUND: Treat to target (TTT) is a broad concept for treating patients with rheumatoid arthritis (RA). It involves setting a treatment target, usually remission or low disease activity (LDA). This is often combined with frequent patient assessment and intensive and rapidly adjusted drug treatment, sometimes based on a formal protocol. OBJECTIVE: To investigate the clinical effectiveness and cost-effectiveness of TTT compared with routine care. DATA SOURCES: Databases including EMBASE and MEDLINE were searched from 2008 to August 2016...
