Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C, also known ascorbic acid, does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients according to the results published in the American College of Rheumatology (ACR) journal, Arthritis & Rheumatism.
New research suggests that patients with knee osteoarthritis (OA) who wear flat, flexible footwear (mobility shoes) had significant reduction in knee loading—the force placed upon the joint during daily activities. Results published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), show that long term use of the mobility shoes helped OA patients adapt their gait, or how they walk, which improved knee loading, even when the mobility shoes were no longer worn.
A prospective study by U.K. researchers found that adolescents who are double-jointed—medically termed joint hypermobility—are at greater risk for developing musculoskeletal pain as they get older, particularly in the shoulders, knees, ankles and feet. Findings published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), indicate that children with joint hypermobility are approximately twice as likely to develop pain at these joints.
A Phase 3 clinical trial demonstrates that tofacitinib improves disease activity and inhibits progression of joint damage in rheumatoid arthritis (RA) patients who did not respond to methotrexate (MTX). Results of the 12-month interim analysis of the efficacy of tofacitinib appear in Arthritis & Rheumatism, a journal published by Wiley on behalf of the American College of Rheumatology (ACR).
In the first systemic review of evidence assessing complications following total joint arthroplasty, patients with rheumatoid arthritis (RA) were found to have an increased risk for hip dislocation after hip replacement surgery compared to those with osteoarthritis (OA). Study findings published online in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also indicate that RA patients have a higher infection risk following total knee replacement than patients with OA.
A new study reveals that black Americans display lower levels of vitamin D and greater pain sensitivity compared to white Americans. Findings published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), indicate that vitamin D deficiency may be one of many factors that account for increased pain in older black Americans with knee osteoarthritis (OA).
A new study found that patients with gout who consumed cherries over a two-day period showed a 35% lower risk of gout attacks compared to those who did not eat the fruit. Findings from this case-crossover study published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also suggest that risk of gout flares was 75% lower when cherry intake was combined with the uric-acid reducing drug, allopurinol, than in periods without exposure to cherries or treatment.
New research confirms no significant difference in the rates of death among patients with rheumatoid arthritis (RA) who were exposed to one of several TNF inhibitors used to treat RA, adalimumab (Humira), etanercept (Enbrel), and infliximab (Remicade). This population-based study of RA patients in Sweden—the first to compare mortality rates among patients treated with individual TNF inhibitors—is now available in Arthritis & Rheumatism, a journal published by Wiley on behalf of the American College of Rheumatology (ACR).
Researchers from Austria have determined that patients with rheumatoid arthritis (RA) and their doctors differ on perception of RA disease activity. The study now available in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR) and published by Wiley, reports that RA patients cite joint pain as the reason for their perception of a change in their disease activity. Rheumatologists, however, stressed joint swelling as the major determinant for their perception of change in RA disease activity.
New research reveals that rheumatoid arthritis (RA) patients do not receive fewer cancer screening tests than the general population. Results of the study, funded in part by grants from the National Institutes of Health (NIH) and published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), found that RA and non-RA patients receive routine screening for breast, cervical, and colon cancer at similar rates.
As children with juvenile idiopathic arthritis (JIA) grow into adulthood, disability due to disease may adversely affect their ability to achieve educational success. Findings published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), suggest that functional disability impacts educational attainment, which is key to successful employment in adulthood.
African Americans have more severe complications from systemic sclerosis, also known as scleroderma, than Caucasians. Findings published today in, Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), show that compared with Caucasians, African-American patients were more likely to have antibodies that increased frequency and severity of pulmonary fibrosis, which is associated with decreased survival.
Children with juvenile idiopathic arthritis (JIA) have higher rates of hospitalized bacterial infection than children without JIA according to an observational study appearing in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR). The findings show that the risk of infection among JIA patients was significantly increased with use of high-dose glucocorticoids (steroids). Methotrexate (MTX) and tumor necrosis factor alpha (TNF) inhibitors were not found to increase infection risk in this pediatric population.
Not Taking Gastroprotective Drugs Prescribed with Anti-inflammatory Medicines Increases Risk of Upper GI Complications
To relieve pain, arthritis sufferers are prescribed medications that may include non-steroidal anti-inflammatory drugs (NSAIDs) or cyclooxygenase-2 (COX-2) inhibitors, both of which can irritate the digestive tract. At times additional drugs are co-prescribed with NSAIDs or COX-2 inhibitors to prevent adverse gastrointestinal (GI) effects. Now a new study available today in the American College of Rheumatology journal, Arthritis & Rheumatism, reveals that decreasing gastroprotective agent (GPA) adherence among users of COX-2 inhibitors is linked to an increased risk of such upper GI complications.
The American College of Rheumatology has released the first classification criteria for polymyalgia rheumatica – aimed at helping physicians identify patients with this condition, which occurs in persons aged 50 years or older who have recent onset of pain in the shoulders, neck and hips along with other inflammatory symptoms not explained by an alternate diagnosis.
New research reports that incident malignancy among children with juvenile idiopathic arthritis (JIA) is four times higher than in those without the disease.
One of the largest studies to investigate lumbar spine disc degeneration found that adults who are overweight or obese were significantly more likely to have disc degeneration than those with a normal body mass index (BMI). Assessments using magnetic resonance imaging (MRI) show elevated BMI is associated with an increased number of levels of degenerated disks and greater severity of disc degeneration, including narrowing of the disc space. Details of this study now appear in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).
Researchers in Finland found that annual cumulative incidences of partial and total knee arthroplasty, commonly known as knee replacement surgery, rose rapidly over a 27-year period among 30 to 59 year-olds in that country, with the greatest increase occurring in patients aged 50 to 59 years. According to the study published today in Arthritis & Rheumatism, a peer-reviewed journal of the American College of Rheumatology (ACR), incidences were higher in women throughout the study period.
A phase II clinical trial found that rilonacept, an inhibitor of the protein interleukin-1 (IL-1), significantly reduced acute gout flares that occur when initiating uric acid-lowering therapy.
New research shows 63% of women age 50 and older reported persistent, incident, or intermittent knee pain during a 12-year study period.
