In preclinical models of permanent middle cerebral artery occlusion, neurological outcomes correlate closely with blood or plasma glutamate levels. Previous attempts to reduce glutamate-induced excitotoxicity after stroke have included inhibition of glutamate receptors and administration of pyruvate and oxaloacetate. These strategies, including competitive and non-competitive glutamate receptor antagonists improved preclinical stroke outcomes but were without favorable outcomes or had significant unfavorable side-effects in human trials. We propose to decrease glutamate levels via an alternative mechanism, which should improve survival and neurological outcomes, without drug-induced side effects and complications. Glutamate, glutamate oxaloacetate transaminase and glutamate pyruvate transaminase concentrations are decreased during standard 4-hour long hemofiltration in chronic renal failure patients.enIschemic strokehemofiltrationinnovative scientific researchAbstract
