Prognostic utility of early plasma matrix metalloproteinases -2 and -9 concentrations after severe traumatic brain injury.

Increased plasma matrix metalloproteinase -9 levels were associated with intensive care unit mortality following severe traumatic brain injury, regardless of the presence of extracerebral injuries. Conversely, in this same context, plasma matrix metalloproteinase -2 levels were not associated with short-term fatal outcome prediction.
