Sir William Osler, the father of modern medicine, said “the desire to take medicine is perhaps the greatest feature that separates man from animal.” Determination of the benefit of a medication can be challenging and includes a number of factors, such as pharmacologic activities on the disease pathophysiology, pharmacokinetic properties and patient characteristics.1,2 An additional,…
CHICAGO—The placebo effect in treating pain in osteoarthritis (OA) should not be discounted, an expert said at the ACR State-of-the-Art Clinical Symposium in April. It’s especially important to accept the effect as real considering that trials of pain therapies in OA generate such high placebo effects (typically at least 40%) and that OA treatment options,…
“Wait. I can explain.” One could imagine this phrase coming up under many conditions in daily life. When I first became a physician, however, I would never have expected to use this phrase in my clinic. In medical school, I was taught the importance of dialogue in establishing a relationship with a patient. Statistics indicate…
A two-year study among patients with knee osteoarthritis (OA) showed that steroid injections for knee pain were no more effective than saline injections and actually reduced cartilage volume more than placebo. The study, conducted at Tufts Medical Center in Boston, looked at progression of cartilage loss and change in knee pain after treatment with placebo…
NEW YORK (Reuters Health)—Brain connectivity differences predict placebo responses in patients with chronic knee osteoarthritis, researchers report. Positive medical responses to placebo treatments are common, but the underlying central nervous system mechanisms remain unclear. Dr. Marwan N. Baliki and colleagues from the Feinberg School of Medicine at Northwestern University in Chicago used resting-state functional MRI…
(Reuters Health)—Glucosamine sulfate and chondroitin sulfate are not more beneficial than placebo treatments for patients with knee osteoarthritis, a recent trial suggests. In a double-blind study, researchers investigated the efficacy of a medicine that delivered both glucosamine and chondroitin sulfate. The 164 participants all had osteoarthritis and moderate to severe knee pain. Half the participants…
NEW YORK (Reuters Health)—Some placebos are more effective than others, and these differences can influence the apparent outcomes of clinical trials, according to a systematic review and meta-analysis of osteoarthritis trials. “More surprising than the fact that all placebos are not equal is the magnitude of that difference,” Dr. Raveendhara R. Bannuru, from Tufts Medical…
Can rheumatologists harness the placebo effect to improve patient care?
