Protein test is first to predict rate of progression in Lou Gehrig’s disease
Date:11/19/2012

JACKSONVILLE, Fla. A novel test that measures proteins from nerve damage that are deposited in blood and spinal fluid reveals the rate of progression of amyotrophic lateral sclerosis (ALS) in patients, according to researchers from Mayo Clinic's campus in Florida, Emory University and the University of Florida.

Their study, which appears online in the Journal of Neurology, Neurosurgery & Psychiatry, suggests this test, if perfected, could help physicians and researchers identify those patients at most risk for rapid progression. These patients could then be offered new therapies now being developed or tested.

ALS also known as Lou Gehrig's disease is a progressive neurodegenerative disease caused by deterioration of motor neurons (nerve cells) that control voluntary muscle movement. The rate of progression varies widely among patients, and survival from the date of diagnosis can be months to 10 years or more, says Kevin Boylan, M.D., medical director of the ALS Clinic at Mayo Clinic in Florida.

"In the care of our ALS patients there is a need for more reliable ways to determine how fast the disease is progressing," says Dr. Boylan, who is the study's lead investigator. "Many ALS researchers have been trying to develop a molecular biomarker test for nerve damage like this, and we are encouraged that this test shows such promise. Because blood samples are more readily collected than spinal fluid, we are especially interested in further evaluating this test in peripheral blood in comparison to spinal fluid."
