The body uses B cells to produce antibodies that can fight off infection by invading antigens and bacteria. But in rheumatoid arthritis (RA), the immune system produces autoantibodies that work against the body’s proteins to attack joint tissues. Researchers believe this process is helped along by autoreactive B cells that live in bone matter and…
Detecting interstitial lung disease in RA patients can be challenging. But evaluating risk factors and the use of imaging can help clinicians identify and manage this condition in patients…
Pain can deter patients with rheumatic disease from engaging in physical activity. But the latest research shows exercise helps reduce pain, & other influences may also affect patients’ activity levels, particularly after surgery…
A new study adds to the evidence that metabolic factors play an important role in the pathogenesis of rheumatoid arthritis (RA). In this large, prospective cohort study, Liu et al. found that increased physical activity among women was associated with a reduced risk of RA…
Methotrexate (MTX) remains the predominant medication used by rheumatologists to treat rheumatoid arthritis (RA). Doses of 7.5–25 mg per week with daily folic acid are generally prescribed. Despite its common use, MTX must be prescribed cautiously given the potential adverse effects when taken incorrectly or without folic acid supplementation. Cases of MTX-induced cutaneous ulceration have…
Over the past few years, biosimilars and other new drugs have been introduced to treat rheumatic illnesses. Some of the conditions we treat have numerous drug options, others have few or only off-label options. This series, “Rheumatology Drugs at a Glance,” provides streamlined information on the administration of biologic, biosimilar and small molecule inhibitor drugs…
Rheumatoid arthritis (RA) is one of the most common autoimmune diseases. One hypothesis is that inflammation in the respiratory tract results in autoantibody formation that later leads to disease. Kronzer et al. set out to narrow the knowledge gaps related to the oral-respiratory factors that may mediate RA pathogenesis.
Pregnant women with inflammatory arthritis may have an increased risk for preterm delivery. New research examined the risk of preterm delivery and other pregnancy complications in women with RA and JIA vs. healthy controls…
The ACR’s nonpartisan political action committee is continuing to advocate for increased defense department funding for rheumatology research. Learn about RheumPAC’s efforts and how you can help.
Interstitial lung disease (ILD) can be associated with rheumatoid arthritis (RA) with significant morbidity and mortality. An article in The Journal of Rheumatology focused on calculating the prevalence, incidence, mortality and costs to the healthcare system of RA-related ILD (RA-ILD).1 “RA is the most common of connective tissue diseases encountered by rheumatologists—affecting about 1% of…
