STUDY OBJECTIVE: We describe a subset of patients with toxin-related precipitants of seizures/status epilepticus enrolled in the Established Status Epilepticus Treatment Trial (ESETT).
METHODS: The ESETT was a prospective, double-blinded, adaptive trial evaluating levetiracetam, valproate, and fosphenytoin as second-line agents in benzodiazepine-refractory status epilepticus in adults and children. The primary outcome was the absence of seizures and improvement in the level of consciousness 1 hour after study drug administration. In this post hoc analysis, the safety and efficacy of second-line agents in a subset of patients with toxin-related seizures are described.
RESULTS: A total of 249 adults and 229 children were enrolled in the ESETT. Toxin-related seizures occurred in 29 (11.6%) adults and 1 child (0.4%). In adults, men were more likely to have toxin-related seizures than women (25 of 145, 17.2% versus 4 of 104, 3.9%). The most common toxin-related precipitants were alcohol withdrawal and cocaine, 11(37%) of 30 patients each. Cocaine was used with other substances by most patients 10 (91%) of 11, most commonly with an opioid 7 (64%) of 11. For alcohol withdrawal-related seizures, treatment successes with levetiracetam, valproate, and fosphenytoin were 3 (100%) of 3, 3 (50%) of 6, and 1 (50%) of 2, respectively. For cocaine-related seizures, treatment success was 1 (14%) of 7 for levetiracetam, 0 (0%) of 1 for valproate, and 1 (33%) of 3 for fosphenytoin. One patient who used cocaine and an opioid received fosphenytoin and developed life-threatening hypotension.
CONCLUSION: In the ESETT, approximately 1 in 10 adult patients with status epilepticus presented with a toxin-related seizure. Alcohol withdrawal and cocaine/opioid use were the most common toxin-related precipitants. Toxin-related benzodiazepine-refractory status epilepticus was successfully treated with a single dose of second-line antiseizure medication in 42% of the patients.
