A news release from the NIH:
Investment in Parkinson's Disease Data Bank Yields Potential Therapy
12th October, 2009
Individuals with Parkinson's disease who have higher levels of a metabolite called urate in their blood and in cerebrospinal fluid (CSF) have a slower rate of disease progression, according to a study funded by the National Institutes of Health. A clinical trial is under way to examine the safety and potential benefits of supplemental urate elevation for recently diagnosed Parkinson's patients who have low urate levels.
Investigators demonstrated the link with urate by mining a repository of clinical data and tissue samples collected from Parkinson's patients more than 20 years ago as part of a pioneering study called DATATOP, funded by NIH's National Institute of Neurological Disorders and Stroke (NINDS). The new study appears in Archives of Neurology. It was funded primarily by NINDS, with additional support from the Department of Defense and private organizations.
"This study speaks to the value of saving data and biospecimens from large clinical studies, and making them available to the research community to pursue new, unanticipated ideas," said Michael Schwarzschild, M.D., Ph.D., an associate professor of neurology at Massachusetts General Hospital in Boston, who lead the study together with Alberto Ascherio, M.D., Dr.PH, a professor of epidemiology and nutrition at the Harvard School of Public Health.
