Abstract:
Super-refractory status epilepticus (SRSE) is associated with high morbidity and mortality. Treatment of SRSE is complicated by progressive cortical hyperexcitability believed to result in part from synaptic GABA receptor internalization and desensitization. Allopregnanolone, a neurosteroid that positively modulates synaptic and extrasynaptic GABAA receptors, has been proposed as a novel treatment. We describe the first two patients with SRSE who were each successfully treated with a 120-h continuous infusion of allopregnanolone. Both patients recovered from prolonged SRSE with good cognitive outcomes.
