Summary

Sudden unexpected death in epilepsy (SUDEP) is a tragic outcome of seizure disorders that primarily affect young adults suffering from refractory epilepsy. In this population, SUDEP incidence is estimated at 0.5%. While the mechanisms of SUDEP are not completely understood, it appears that the majority of such death occurs in the immediate aftermath of a general tonic-clonic seizure.

There is currently no validated preventive treatment for SUDEP. Some evidence suggest that modulation of the serotoninergic tone, and more specifically selective serotonin recapture inhibitor (SSRI) such as fluoxetine, might prevent SUDEP. Indeed, fluoxetine prevents seizure-induced lethal central apneas in DBA/2 and DBA/1 mice, one of the few animal models of SUDEP. Furthermore, serotoninergic bulbar nuclei are known to play a major role in the control of breathing, especially during sleep and in response to repeated hypoxia.

In patients with epilepsy undergoing in-hospital video-EEG monitoring, about one third of seizures are associated with decrease in SpO2 \<90%, an abnormality suspected to represent a risk factor of SUDEP. In a retrospective uncontrolled study, patients treated with SSRIs displayed less frequent ictal/post-ictal hypoxemia than patients not taking SSRIs.

The investigators project aimed at testing whether fluoxetine can reduce the risk of ictal/post-ictal hypoxemia by performing a double-blind, randomized, placebo-controlled trial in patients undergoing video-EEG monitoring as part of the pre-surgical evaluation of their focal drug-resistant epilepsy.

Conditions

Interventions

DRUG

fluoxetine 20 mg

Fluoxetine 20 mg per day during 4 weeks prior to video-EEG, then continued during video-EEG. At the end of video-EEG, and according to patient's decision, treatment was either progressively withdrawn (1 week at 10 mg per day and then 1 week at 5 mg per day), or replaced by fluoxetine 20 mg open-label.

DRUG

placebo 20 mg

Placebo 20 mg per day during 4 weeks prior to video-EEG, then continued during video-EEG. At the end of video-EEG, and according to patient's decision, treatment was either progressively withdrawn (1 week at 10 mg per day and then 1 week at 5 mg per day), or replaced by fluoxetine 20 mg open-label.
