(Reuters Health)—People suffering from osteoarthritis, the most common type of joint inflammation, are more likely to have knee pain when they also have difficulty getting enough sleep, a study suggests. Researchers found that people with knee osteoarthritis and insomnia were also more likely to suffer from a nervous system disorder called “central sensitization” that makes…
Zoledronic Acid May Improve Bone Density in Elderly Women
A single injection daily of zoledronic acid may improve bone mineral density (BMD) in frail elderly women in long-term care facilities, a new randomized controlled trial shows. However, the clinical importance of the improvement, observed over a two-year period, remains unclear, Dr. Neil M. Resnick, of the University of Pittsburgh, told Reuters Health in a…
Study Reveals Role of IL-17–Secreting CD4+ T Cells in Lupus
Patients with systemic lupus erythematosus (SLE) are characterized by high-titer, highly specific, isotype-switched antibodies against DNA and RNA. Patients have both CD4+ T helper (Th) cell- dependent as well as Th cell-independent autoantibody production. Two mouse models of lupus demonstrate T-cell–independent autoantibody production: the pristane model of lupus, as well as in the MRL/lpr mouse…
COPA Genetic Mutation Identified in Lung Disease, Arthritis
Researchers from California and Texas have identified a new genetic syndrome that is characterized by systemic autoimmune disease of the lung and joints. The syndrome is driven by a genetic variant of a vesicular transport protein and is the first documented association between intracellular transport and autoimmunity. Levi B. Watkin, PhD, postdoctoral fellow at Baylor…
Rheumatology Research Foundation Funding Aids Researcher’s Career
For 30 years, the Rheumatology Research Foundation has been funding research and advancing treatments. During that time, Leonard L. Dragone, MD, PhD, received a Foundation award to help look for new strategies to treat autoimmune and inflammatory diseases in mouse models. Then, he was working as an assistant professor of pediatrics and immunology at the…
Pain Perception May Depend on Multiple Immediate-Environment Stimuli
Can merely crossing your fingers change the way your brain perceives pain when you touch different stimuli with three fingers? Perhaps so, according to a new study by UK-based researchers, when taken into context with the immediate environment. Changes in posture could potentially provide a way to influence chronic pain if basic science results lead…
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Redefined
A report from the Institute of Medicine that gives new diagnostic criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and recommends a new name for the disorder received mixed reviews from rheumatologists and other physicians.1 “Diagnosing ME/CFS often is a challenge … the new diagnostic criteria will make it easier for clinicians to recognize and accurately…
Lyme Disease Not Predictor of Long-Term Physical, Mental Health Issues
Lyme disease is often considered a cause of chronic fatigue, pain and other incapacitating symptoms. This assumption stems from analyses of patients who seek retreatment for Lyme disease. However, a new study suggests that Lyme disease is not life altering in the long term for most patients. Specifically, patients with culture-confirmed Lyme disease have similar…
Anti-TNF Agents May Improve Clinical Symptoms of Ankylosing Spondylitis
Ankylosing spondylitis primarily affects the joints and ligaments of the spine, but may also have an impact on other joints. Patients experience pain and stiffness that limit mobility in the back and other affected joints. Symptoms can come and go, last for long periods of time and be severe. Anti-tumor necrosis factor (anti-TNF) drugs are…
Rising Costs of Biologics in the U.S. Suggest Need for Negotiation Ability
The costs of some disease-modifying therapies outpace prescription drug inflation, saddling insured patients with thousands of dollars in out-of-pocket payments and delayed or denied coverage, two new studies have shown. Disease-modifying therapies for multiple sclerosis are rising in cost five to seven times faster than inflation and cost more in the United States than in…
