Interactions between an individual’s genetic background and their exposure to environmental factors are thought to result in a cascade of immune reactions, ultimately leading to the development of autoimmune diseases such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic lupus erythematosus (SLE) and juvenile dermatomyositis.1,2 For example, an environmental factor that conclusively affects susceptibility…
Systemic autoimmune diseases are thought to result from immune dysregulation in genetically susceptible individuals who were exposed to environmental risk factors. Many studies have identified genetic risk factors for these diseases, but concordance rates among monozygotic twins are 25–40%, suggesting that nonheritable environmental factors play a more prominent role.1,2 Through carefully conducted epidemiologic and other…
Preventing adverse outcomes in individuals who have rheumatic diseases is a daily goal for rheumatologists. For example, rheumatologists prescribe medications and perform screening to prevent erosions in rheumatoid arthritis (RA), renal failure in systemic lupus erythematosus and flares across all diseases. Many of these actions are classified as secondary or tertiary prevention, because individuals have…
NEW YORK (Reuters Health)—Anti-citrullinated protein antibodies (ACPA), particularly high anti-CCP2 titers, can diagnose rheumatoid arthritis (RA) in the general population with a high degree of accuracy, a Swedish study suggests. ACPA are highly specific for RA, but until now the diagnostic accuracy of ACPA in the general population has not been “thoroughly assessed,” note Dr….
