BACKGROUND Infection by common viruses has long been discussed in the aetiology of a number of autoimmune diseases, including rheumatoid arthritis (RA). However, studies investigating this hypothesis in RA show conflicting results. These studies often lack well-matched control populations, and many do not include data on autoantibodies, genetic risk factors and other environmental factors, whic...
In their letter, Van Steenbergen and colleagues present data on the radiographic progression in rheumatoid arthritis (RA) patients stratified for anti-citrullinated protein antibody (ACPA) and rheumatoid factors (RFs) in two different patient cohorts. They show that the presence of ACPA is associated with a more pronounced progression of structural damage when scoring conventional radiographs b...
OBJECTIVE An interesting and so far unexplained feature of chronic pain in autoimmune disease is the frequent disconnect between pain and inflammation. This is illustrated well in rheumatoid arthritis (RA) where pain in joints (arthralgia) may precede joint inflammation and persist even after successful anti-inflammatory treatment. In the present study, we have addressed the possibility that au...
OBJECTIVE The co-occurrence of rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) positivity in rheumatoid arthritis (RA) is well described. However, the mechanisms underlying the potential interaction between these 2 distinct autoantibodies have not been well defined. The aim of this study was to evaluate the epidemiologic and molecular interaction of ACPAs and RF and its as...
OBJECTIVES Lung exposures including cigarette smoking and silica exposure are associated with the risk of rheumatoid arthritis (RA). We investigated the association between textile dust exposure and the risk of RA in the Malaysian population, with a focus on women who rarely smoke. METHODS Data from the Malaysian Epidemiological Investigation of Rheumatoid Arthritis population-based case-cont...
هدف از تحقیق حاضر بررسی نقش رسپتور های cb1 کانابینوئیدی ناحیه آمیگدال مرکزی در پاداش ناشی از مرفین در موش نر بزرگ آزمایشگاهی نژاد wistar می باشد. نتایج به دست آمده نشان داد که سه روز تزریق زیر جلدی مرفین (2, 4, 6 mg/kg ) می تواند ترجیح مکان شرطی شده وابسته به مقدار را در این حیوانات القاء کند. مرفین هیچ گونه اثری بر فعالیت حرکتی موش شرطی شده در زمان انجام آزمون نداشت. تزریق درون مغزی آگونیست رس...
BACKGROUND 14-3-3η (eta) is a novel serum/plasma protein biomarker involved in the upregulation of inflammatory and joint damage factors. We analysed the association of 14-3-3η with the development of clinically apparent arthritis in a cohort of subjects with arthralgia and positivity for at least one serologic marker: rheumatoid factor (RF) or anti-citrullinated protein antibody (ACPA). METH...
BACKGROUND Rheumatoid arthritis (RA) is an autoimmune inflammatory disease affecting the joints. Anti-citrullinated protein antibodies (ACPA) are frequently found in RA. Previous studies identified a citrullinated epitope in cartilage proteoglycan (PG) aggrecan that elicited pro-inflammatory cytokine production by RA T cells. We recently reported the presence of ACPA-reactive (citrullinated) PG...
OBJECTIVES Our study analyses the prevalence of ANA, anti-SS-A, anti-SS-B, and ACA and ACPA antibodies in patients with pSS and with dryness symptoms without pSS confirmation, and the association of ACPA and ACA antibodies with specific clinical symptoms. MATERIALS AND METHODS 113 patients were divided into two groups: I - with diagnosed pSS (N = 75); and II - with dryness without pSS evidenc...
OBJECTIVE To examine how anti-citrullinated protein antibody (ACPA) epitope spreading takes place prior to the onset of clinical rheumatoid arthritis (RA), and to analyze the pattern of autoantigen reactivity at the beginning of the immune response. METHODS Multiple consecutive serum samples from 79 RA patients who had donated blood before disease onset were available for analysis. Fifty-thre...
