Objectives: Evaluate long-term effectiveness and tolerability of brivaracetam in clinical practice in patients with focal epilepsy. Materials and Methods:This was a multicenter retrospective study. Patients aged ≥16 years were started on brivaracetam from November 2016 to June 2017 and followed over 1 year. Data were obtained from medical records at 3, 6 and 12 months after treatment initiation for evaluation of safety-and seizure-related outcomes.Results: A total of 575 patients were included in analyses; most had been treated with ≥4 lifetime antiepileptic drugs. Target dosage was achieved by 30.6% of patients on the first day. Analysis of primary variables at 12 months revealed that mean reduction in seizure frequency was 36.0%, 39.7% of patients were ≥50% responders and 17.5% were seizure-free. Seizure-freedom was achieved by 37.5% of patients aged ≥65 years. Incidence of adverse events (AEs) and psychiatric AEs (PAEs) was 39.8% and 14.3%, respectively, and discontinuation due to these was 8.9% and 3.7%, respectively. Somnolence, irritability, and dizziness were the most frequently reported AEs. At baseline, 228 (39.7%) patients were being treated with levetiracetam; most switched to brivaracetam (dose ratio 1:10-15). Among those who switched because of PAEs (n = 53), 9 (17%) reported PAEs on brivaracetam, and 3 (5.7%) discontinued because of PAEs. Tolerability was not highly affected among patients with learning disability or psychiatric comorbidity. Conclusions:In a large population of patients with predominantly drug-resistant epilepsy, brivaracetam was effective and well-tolerated; no unexpected AEs occurred over 1 year, and the incidence of PAEs was lower compared with levetiracetam.

Our series describes a so far not well-recognized autoimmune association of pilomotor seizures to limbic encephalitis. This etiology should be ruled out through a comprehensive diagnostic work-up even in cases of long-lasting TLE with typical hippocampal atrophy on MRI.

Objective The pharmacokinetics of brivaracetam (BRV), added to its effectiveness observed in animal models of status epilepticus (SE), makes this drug attractive for use in emergency situations. Our objective was to evaluate the use of intravenous BRV in a multicenter study. Methods A retrospective multicenter registry of SE cases treated with BRV was created. These patients were evaluated between January and December 2018 at seven hospitals in Spain. Demographic variables, SE characteristics, concomitant drugs, loading doses, and response to treatment were collected. Results Forty‐three patients were registered. The mean age was 56 ± 23.1 years, 51.2% were male, 29 had previous epilepsy, 24 (55.8%) had prominent motor symptoms, and 19 had nonconvulsive symptoms. Regarding the etiology, 19 (44.2%) were considered acute symptomatic, 16 (17.2%) remote symptomatic, four (9.3%) progressive symptomatic, and four (9.3%) cryptogenic. Regarding concomitant antiepileptic drugs (AEDs), 17 had previously received levetiracetam (LEV). In 14 patients, BRV was used early (first or second AED). The median loading dose was 100 mg (range = 50‐400), and the weight‐adjusted dose was 1.8 mg/kg (range = 0.4‐7.3). BRV was effective in 54% (n = 23), and a response was observed in <6 hours in 13 patients. We observed a tendency for it to be more effective when administered earlier (P = 0.09), but there were no differences regarding SE type and the concomitant use of LEV. In those with the fastest responses, we observed that both the total administered dose (300 mg vs 100 mg, P = 0.008) and the weight‐adjusted dose (3.85 mg vs 1.43 mg, P = 0.006) were significantly higher. The receiver operating characteristic curve showed that the best cutoff point for a faster response was 1.82 mg/kg. Significance BRV is useful for the treatment of SE, even when patients are already being treated with LEV. The response rate seems higher when it is administered earlier and at higher doses (>1.82 mg/kg).

Lacosamide was effective and well tolerated as early add-on treatment in patients who had received one or two previous AEDs.
