Early vigabatrin to augment GABAergic pathways in post-anoxic status epilepticus
The outcomes of patients who experience status epilepticus during the post-cardiac arrest period, or post-anoxic status epilepticus (PASE), remain dismal despite advances in resuscitation. The combination of therapeutic nihilism and the refractoriness of seizures in a setting where pessimistic prognostic impressions prevail is likely the main driver of such poor outcomes. The resulting pervasive vicious cycle perpetuates this knowledge gap, whereby hypoxic-ischemic insults as the etiology for seizures remain a ubiquitous exclusion criterion for clinal trials in status epilepticus. Effective therapies targeting hyperexcitability resulting from hypoxic-ischemic brain injury are urgently needed. Early inhibition of gamma-aminobutyric acid (GABA) transaminase with vigabatrin holds potential as an effective adjunctive therapy for PASE. This scientific premise is based on the resulting halted GABA catabolism thereby promoting synergistic augmentation of GABAergic pathway when used in combination with positive GABAergic allosteric modulators. This paper is based on a lecture presented at the 9th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures, in London 8–10 April 2024.
期刊介绍:
Epilepsy & Behavior is the fastest-growing international journal uniquely devoted to the rapid dissemination of the most current information available on the behavioral aspects of seizures and epilepsy.
Epilepsy & Behavior presents original peer-reviewed articles based on laboratory and clinical research. Topics are drawn from a variety of fields, including clinical neurology, neurosurgery, neuropsychiatry, neuropsychology, neurophysiology, neuropharmacology, and neuroimaging.
From September 2012 Epilepsy & Behavior stopped accepting Case Reports for publication in the journal. From this date authors who submit to Epilepsy & Behavior will be offered a transfer or asked to resubmit their Case Reports to its new sister journal, Epilepsy & Behavior Case Reports.
