NEW YORK (Reuters Health)—Children of women with rheumatoid arthritis (RA) who are exposed to tumor necrosis factor-alpha inhibitors (TNFis) in the womb are not at markedly increased risk of serious infections, new findings suggest. “It’s reassuring for mothers who need to take these medications during pregnancy,” Evelyne Vinet, MD, of McGill University Health Center in…
Gut Microbiota Directly Affects Inflammatory Arthritis
Gut microbiota may provide insight into important environmental triggers for autoimmune diseases. New research in mice indicates that intestinal dysbiosis triggers a mucosal immune response that stimulates T and B cells, which are critical to the development of inflammatory arthritis…
RA Patients May Not Receive Needed Osteoporosis Screening & Treatment
New research examined the frequency of osteoporosis screening and treatment for RA patients from 2003–2014, including four years following the release of the 2010 ACR guideline on glucocorticoid-induced osteoporosis prevention and treatment. The results: Approximately half of RA patients for whom treatment was indicated never received osteoporosis medication. Researchers also found that RA patients, despite their increased risk for developing osteoporosis, were not more likely to receive osteoporosis care than OA patients…
Obesity Linked with Disability in RA
(Reuters Health)—Patients with rheumatoid arthritis (RA) may be more likely to become disabled if they’re obese, a U.S. study suggests. Researchers examined data on more than 25,000 patients with RA. Most were overweight or obese when they joined the study. Those who were severely obese were more likely to report some disability at baseline. Over…
FDA Staff Raises Safety Concerns Over Arthritis Drug Baricitinib
(Reuters)—An experimental rheumatoid arthritis drug developed by Eli Lilly and Co. and Incyte Corp. poses serious risks of deadly blood clots at higher doses, U.S. Food and Drug Administration staff says, the latest setback to a treatment regulators declined to approve last year. New data provided by the companies in a resubmission of their marketing…
Upadacitinib Proves Superiority to Adalimumab in Phase 3 RA Study
Initial results from an ongoing trial show that upadacitinib outperforms adalimumab in achieving ACR20 in patients with rheumatoid arthritis…
Periodontitis May Provide Insight into RA
Researchers explored the role of carbamylated protein (CarP) and neutrophil extracellular traps (NETs) in periodontitis and rheumatoid arthritis (RA). The results showed significantly higher levels of CarP and NETs in patients with both RA and periodontitis than in healthy controls. The data suggest that RA and periodontitis may share an underlying pathogenic mechanism…
Synovial Analysis Identifies Distinct Rheumatoid Arthritis Subtypes
NEW YORK (Reuters Health)—Synovial gene expression and histology can be used to divide rheumatoid arthritis (RA) into high, low, and mixed inflammatory subtypes, according to results from the Accelerating Medicine Partnership: RA/SLE Network. “The actionable implication of these findings is that it may be worth considering synovial biopsies in patients who are not responding to…
Baricitinib Also Appears Effective in Biologic-Refractory RA
NEW YORK (Reuters Health)—The selective Janus kinase 1 and 2 inhibitor baricitinib appears also to help patients whose rheumatoid arthritis (RA) has not responded adequately to biologic disease-modifying antirheumatic drugs, according to results from the RA-BEACON randomized trial. The previously published overall results from RA-BEACON showed that baricitinib-treated patients had significantly better functional and clinical…
Etanercept Biosimilar Is Effective, Well-Tolerated for Rheumatoid Arthritis
NEW YORK (Reuters Health)—The biosimilar LBEC0101 is equivalent to etanercept (Enbrel) in treating patients with rheumatoid arthritis (RA) who respond inadequately to methotrexate, according to researchers from Korea and Japan. As Dr. Yeong-Wook Song tells Reuters Health by email, “LBEC0101 is comparable in efficacy, safety and immunogenicity profile to Enbrel.” The findings, he adds, could…
