The development of drugs and other treatments for specific symptoms or conditions relies heavily on either serendipity (the chance finding of a beneficial effect) or on an understanding of underlying mechanisms.
In pain, for example, there are limited ways in which we can block pain signals –- such as activating opiate receptors, or inhibiting prostaglandins. There are only so many ways in which you can interact with these systems. The discovery of a novel mechanism of modulating pain is therefore most welcome, and has the potential of leading to entirely new treatments that may have a better side effect profile than existing treatments and also have an additive clinical effect.
A recent study by Nana Goldman et. al., published in Nature Neuroscience, adds to our understanding of pain relief by identifying the role of adenosine in reducing pain activity in the peripheral nervous system. The researchers, in a nice series of experiments, demonstrated that producing a local painful stimulus in mice causes the local release of ATP (adenosine triphosphate) that peaks at about 30 minutes. This correlates with a decreased pain response in the mice. Further, if drugs are given that prolong the effect of adenosine, the analgesic effect itself is prolonged. Read more »

Daniel Wallace, MD
The annual American College of Rheumatology conference was held last week in San Francisco. I had the chance to interview Dr. Daniel Wallace, a world expert in lupus (systemic lupus erythematosis) management, to tell me about the latest advances in the treatment of this disease.
Dr. Wallace is currently a Clinical Professor of Medicine at the David Geffen School of Medicine at UCLA. His clinical practice is based at Cedars-Sinai, where he is involved in the care of 2,000 lupus patients, the largest practice of its kind in the United States. The Wallace Rheumatic Disease Research Center currently runs over 30 clinical trials for patients with lupus and other rheumatic diseases. Dr. Wallace is the author of 6 medical textbooks, 15 book chapters, and over 200 medical publications.

Dr. Val: What is Lupus?
Dr. Wallace: Lupus is what happens when the body becomes allergic to itself. It’s the opposite of cancer and AIDS. There are probably about 1 million people living with lupus in the United States. Ninety percent of them are women, and 90% develop lupus during their reproductive years.
Dr. Val: Historically speaking, what has treatment been like for patients with lupus, and how has that changed over the years? Read more »
