Approval for golimumab (which will by marketed under the trade name Simponi) was granted this week by the U.S. Food and Drug Administration. The drug received approval for the treatment of moderate to severe RA (in conjunction with methotrexate), active psoriatic arthritis (as monotherapy or with methotrexate), and active ankylosing spondylitis at a dose of […]
Cases of new onset psoriasis in patients receiving TNF inhibitors for the treatment of rheumatoid arthritis (RA) have been reported; however, case reports do not permit the calculation of drug-associated incidence rates. Here, Harrison et al (Ann Rheum Dis 2009; 68: 209) compare incident psoriasis in TNF inhibitor treated vs. untreated patients enrolled in the […]
RA patients who use methotrexate have been shown to have lower cardiovascular mortality compared to non-users; however, the mechanism underlying this protection is unclear. Here, Reiss et al (Arthritis Rheum 2008; 58(12): 3675) explore the atheroprotective effects of methotrexate in an experimental model of atherogenesis. Methods THP-1 monocytes/macrophages and human donor peripheral blood mononuclear cells […]
The efficacy of rituximab, a monoclonal antibody directed against CD20 positive B cells, has been demonstrated for the treatment of rheumatoid arthritis (RA) in a number of key studies. However, not all patients respond to therapy. Whether patients with initial non-response may benefit from follow-up treatments (i.e. initial treatment resistance) has not been investigated.
Antibodies against citrullinated proteins have emerged as powerful diagnostic and prognostic tools in RA that may contribute to the initiation phases of the disease. The enzymes that catalyze the citrullination process, known as peptidyl argenine deiminases (or PADs), may also be involved in the initiation and propagation steps of the RA disease process. Additionally, autoimmunity to these catalysts may identify a subset of RA patients with unique disease phenotypes.
