Purpose
Lacosamide (LCM) is an effective antiepileptic drug (AED) approved for the treatment of focal epilepsy in both children and adults. The aim of this observational study was to review our centre’s experience with LCM and to characterise its efficacy and tolerability as an adjunct therapy in children with refractory focal epilepsy.
Methods
We retrospectively reviewed the medical records of 12 paediatric patients who underwent treatment with LCM from January 2014 to December 2015. We recorded the treatment response at three time points: at 3 and 6 months after LCM therapy and at the final follow-up visit. Children showing seizure reduction ≥ 50% were considered responders.
Results
We included 12 patients (five boys), and their mean age was 13.8 years (range: 6.2–17.6 years) at the end of LCM treatment. The average length of follow-up after starting LCM was 23 months (11–37 months). Eight patients (66%) had > 50% reduction in seizures at the 3-month follow-up visit, and seven (58%) had > 50% reduction at the 6-month follow-up visit. Six patients (50%) maintained ≥ 50% reduction in seizures at the final follow-up visit. Two patients (16.6%) were seizure free at the 6-month and final follow-up visits. Common adverse side effects included dizziness, ataxia, nausea, and vomiting. Two patients developed status epilepticus (SE), one each at 3 and 11 days after the first LCM dose; they both discontinued treatment.
Conclusions
Our study points to the efficacy of LCM in a small paediatric group. Furthermore, it was important to report status epilepticus after LCM administration in the paediatric population for the first time.
