Pain is not a symptom of arthritis, pain causes arthritis

Pain is more than a symptom of osteoarthritis, it is an inherent and damaging part of the disease itself, as per a research studypublished recently in journal Arthritis and Rheumatism More specifically, the study revealed that pain signals originating in arthritic joints, and the biochemical processing of those signals as they reach the spinal cord, worsen and expand arthritis. In addition, scientists observed that nerve pathways carrying pain signals transfer inflammation from arthritic joints to the spine and back again, causing disease at both ends........

Supplements no better than placebo in slowing cartilage loss

In a two-year multicenter study led by University of Utah doctors, the dietary supplements glucosamine and chondroitin sulfate performed no better than placebo in slowing the rate of cartilage loss in the knees of osteoarthritis patients. This was an ancillary study concurrently conducted on a subset of the patients who were enrolled in the prospective, randomized GAIT (Glucosamine/chondroitin Arthritis Intervention Trial). The primary objective of this ancillary study was to investigate whether these dietary supplements could diminish the structural damage of osteoarthritis. The results, reported in the recent issue of Arthritis and Rheumatism, show none of the agents had a clinically significant effect on slowing the rate of joint space width loss the distance between the ends of joint bones as shown by X-ray........

New test to diagnose osteoarthritis early

A newly developed medical imaging technology may provide doctors with a long-awaited test for early diagnosis of osteoarthritis (OA), researchers from New York reported today at the 236th National Meeting of the American Chemical Society. By far the most common form of arthritis, OA is a bane of the Baby Boom generation, causing joint pain and disability for more than half of those over 65 nearly 21 million people in the United States........

How rheumatoid arthritis causes bone loss

Scientists have discovered key details of how rheumatoid arthritis (RA) destroys bone, as per a research studyreported in the Aug. 22 edition of the Journal of Biological Chemistry The findings are already guiding attempts to design new drugs to reverse RA-related bone loss and may also address more common forms of osteoporosis with a few adjustments........

Regular tipple may curb risk of rheumatoid arthritis

Alcohol cuts the risk of developing rheumatoid arthritis by up to 50%, reveals research published ahead of print in the Annals of the Rheumatic Diseases. The Scandinavian scientists base their findings on more than 2750 people taking part in two separate studies, which assessed environmental and genetic risk factors for rheumatoid arthritis........

Toward Ending Cartilage Loss

Researchers have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage's natural ability to act as the body's shock absorber. But that solution is temporary, requiring follow-up injections. Now Brown University nanotechnology specialist Thomas Webster has found a way to regenerate cartilage naturally by creating a synthetic surface that attracts cartilage-forming cells. These cells are then coaxed to multiply through electrical pulses. It's the first study that has shown enhanced cartilage regeneration using this method; it appears in the current issue of the Journal of Biomedical Materials Research, Part A........

Recommendations for Rheumatoid Arthritis Therapy

To manage the painful and incapacitating symptoms of rheumatoid arthritis (RA), a chronic, inflammatory joint disease, the majority of patients rely on disease-modifying antirheumatic drugs (DMARDs). In addition to trusted nonbiologic DMARDs, many biologic agents now promise to improve therapy for RA. The American College of Rheumatology (ACR), respected worldwide for its devotion to fostering excellence in patient care, has not updated recommendations for non-biologic DMARDs since 2002 and has not previously developed recommendations for biologic agents. In view of that, ACR decided it was time for a major re-evaluation of the use of DMARD treatment in rheumatoid arthritis........

Cause of lupus

Scientists at Wake Forest University have uncovered evidence that the abnormal editing of gene messages in a type of white blood cell may be behind the development of lupus. Researchers hope the finding will lead to earlier diagnosis, a way to monitor patients response to treatment and possibly a new way to treat the disease........

Women who breastfeed for more than a year

Women who breast feed for longer have a smaller chance of getting rheumatoid arthritis, suggests a study published online ahead of print in the Annals of the Rheumatic Diseases. The study also observed that taking oral contraceptives, which are suspected to protect against the disease because they contain hormones that are raised in pregnancy, did not have the same effect. Also, simply having children and not breast feeding also did not seem to be protective........

Back pain may be in your genes

What do you learn by looking at the spines of hundreds of Finnish twins? If you are the international team of scientists behind the Twin Spine Study, you find compelling proof that back pain problems may be more a matter of genetics than physical strain. The findings of the Twin Spine Study, an ongoing research program started in 1991, have led to a dramatic paradigm shift in the way disc degeneration is understood. Last month a paper presenting an overview of the Twin Spine Studys multidisciplinary investigation into the root causes of disc degeneration received a Kappa Delta Award from the American Academy of Orthopaedic Surgeons, arguably the most prestigious annual award in musculoskeletal research........

Vegan Diet Promotes Atheroprotective Antibodies

A gluten-free vegan diet may improve the health of patients with rheumatoid arthritis, as per new research from Karolinska Institutet. The diet has a beneficial effect on several risk factors for cardiovascular disease. Rheumatoid arthritis is linked to an increased risk of atherosclerosis (hardening of the arteries) and cardiovascular diseases. The underlying causes are unknown, but scientists suspect that the disturbed balance of blood fats seen in patients with rheumatoid arthritis may be part of the explanation........

new light on inflammatory diseases

Investigators at Hospital for Special Surgery have identified a new mechanism involved in the pathogenesis of inflammatory diseases such as rheumatoid arthritis. The mechanism may also shed some light on why gene treatment experiments that use adenoviruses to deliver genes to humans have run into problems. The study will appear online on March 16 in the journal Nature Immunology........

A new view of drugs used to treat rheumatoid arthritis

Powerful drugs used to treat patients with rheumatoid arthritis have a profound, previously unrecognized effect on the immune system, breaking up molecular training camps for rogue cells that play an increasingly recognized role in autoimmune diseases like rheumatoid arthritis and lupus. A team of physicians and researchers at the University of Rochester Medical Center reports that drugs known as anti-TNF compounds which include drugs such as Enbrel, Humira and Remicade affect our B cells, which play a role in a number of autoimmune diseases........

Osteoarthritis and index to ring finger length ratio

Index to ring finger length ratio (2D:4D) is a trait known for its sexual differences. Men typically have shorter second than fourth digits; in women, these fingers tend to be about equal in length. Smaller 2D:4D ratios have intriguing hormonal connections, including higher prenatal testosterone levels, lower estrogen concentrations, and higher sperm counts. Reduction in this ratio has also been associated with athletic and sexual prowess. Whether this trait affects the risk of osteoarthritis (OA), a progressive joint disease linked to both physical activity and estrogen deficiency, has not been examined. Until recently........
