An article based on the report was posted on-line Monday in the Annals of Internal Medicine.
Researchers reviewed published evidence to compare the benefits and harms of three classes of medications: synthetic disease-modifying antirheumatic drugs (DMARDS), biologic DMARDs, and corticosteroids. Synthetic DMARDS include hydroxychloroquine, leflunomide, methotrexate, and sulfasalazine; biologic DMARDS include abatacept, adalimumab, anakinra, etanercept, infliximab, rituximab; and corticosteroids include drugs such as prednisone.
The report concluded that combining methotrexate, a synthetic DMARD, with one of the biologic DMARDs works better than using methotrexate or a biologic DMARD alone. The report also found that methotrexate works as effectively as the biologic DMARDs adalimumab and etanercept for patients who have early rheumatoid arthritis. Adalimumab and etanercept are more likely, however, to show better short-term results as measured by X-rays of joints. The report also emphasized that biologic DMARDs and methotrexate increase the risk of serious infection, including a reoccurrence of tuberculosis.
“Rheumatoid arthritis is a painful, degenerative disease that affects people of all ages and can profoundly impact quality of life,” said AHRQ Director Carolyn M. Clancy, M.D. “This report establishes a clear, unbiased summary of what is known about current treatments. It also identifies areas where more research is needed.”
About 2 million Americans have rheumatoid arthritis, a long-term illness that causes joint and tissue inflammation. Rheumatoid arthritis is an autoimmune disease, meaning that the body confuses healthy tissue for foreign substances and attacks itself. The cause is unknown. The disease often begins with fatigue, morning stiffness, weakness, and muscle aches. Eventually, joint pain appears. Pain may affect the wrists, knees, elbows, fingers, toes, ankles or neck.
Other symptoms may include anemia, eye burning, limited range of motion, skin redness and swollen glands. Joint destruction may occur within 1 to 2 years after the disease appears. Some cases cause deformities. Treatment typically begins with medications but may include physical therapy and surgery.
Katrina Donahue, M.D., M.P.H., an assistant professor of family medicine in the UNC School of Medicine and a fellow in the Cecil G. Sheps Center for Health Services Research at UNC, is lead author of the report. She said additional important findings in the report include:
Combining prednisone with the synthetic DMARD hydroxychloroquine, methotrexate or sulfasalazine works better than using only a synthetic DMARD to reduce joint swelling and tenderness and to improve function.
No meaningful clinical differences can be found between methotrexate and either leflunomide or sulfasalazine
Combining the synthetic DMARDs methotrexate and sulfasalazine is no more effective than using just one of the medications for patients with early rheumatoid arthritis.
Not enough evidence exists to determine whether combining two biologic DMARDs is more effective than using one biologic DMARD.
About 17 of every 1,000 people taking a biologic DMARD for 3 to 12 months have a serious infection. Combining two biologic DMARDs can increase the risk.
Among biologic DMARDS, rates of painful injection site reactions are more common for anakinra (67 percent) than for etanercept (22 percent) or adalimumab (18 percent).
More long-term research is needed on rheumatoid arthritis medications, including how the outcomes of these drugs vary among patients with different health conditions and demographic characteristics. More comparative studies on various combinations of drugs are critical. Also important is investigating whether taking the medications earlier (especially biologic DMARDs) is better for long-term outcomes
The report, Comparative Effectiveness of Drug Therapy for Rheumatoid Arthritis and Psoriatic Arthritis in Adults, was conducted by AHRQ's RTI-UNC Evidence-based Practice Center -- a collaboration between RTI and the five health professions schools and the Cecil G. Sheps Center for Health Services Research at UNC.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
