MIT Study Shows That Commonly Used Drug May Prevent Arthritis
About three million Americans suffer from arthritis as a result of joint injuries that result in slow but steady degradation of their cartilage.
Injuries from sports like basketball or skiing, car accidents, and other similar traumas cause millions of us to have lasting osteoarthritis as a result of these injuries.
A new study shows that there may be hope for preventing this kind of arthritis from ever occurring.
Recent research by scientists at MIT have shown that a steroid drug that is commonly used to treat diseases like arthritis may actually prevent the condition from developing, if given to patients soon after the joint injury occurs.
The study was published in the Journal of Arthritis Research and Therapy in its September 2, 2011 issue, and was written by Alan Grodzinsky, Yihong Lu, both of MIT, and Christopher Evans of Harvard Medical School.
Grodzinsky, the senior author of the study, is a professor of biological, mechanical, and electrical engineering, and the director of MIT's Center for Biomedical Engineering.
The study showed that the onset of cartilage breakdown common to arthritis sufferers was prevented when the damaged tissue was treated immediately with glucocorticoid dexamethasone.
The treatment worked best when the drug was given to patients within one to two days after the injury.
The researchers have not been able to determine if the drug could reverse cartilage damage that already occurred.
However, this is a fertile area for future research.
The scientists are considering studies of animals with existing injuries to see if the treatment reverses the damage.
Additionally, the scientists are examining how best to deliver the drug to the injury and how many treatments of the drug is optimal for preventing future damage.
The study used both human and cow cartilage, which the researchers damaged and then treated with the inflammatory proteins that the body releases after a joint injury.
While the researchers are not yet certain how the drug impacted the injury, it appears that the glucocorticoid dexamethasone blocked the degradation of the cartilage by the proteins.
Until now, typical treatment for this type of injury is to give the patient non-steroidal anti-inflammatory drugs (such as ibuprofen) to reduce pain and swelling, and then perform surgery weeks after the injury to correct some of the damage.
The study suggests that instead, the injury should be treated immediately with the tested drug.
The treatment is exciting because, if further research shows that the drug can correct existing damage to the joints, the drug could quickly be put into circulation for this use since it is already approved for human use.
