    Abstract:
    OBJECTIVE: Eyelid myoclonia with absences (EMA) or Jeavons syndrome characterized by eyelid myoclonia (EM) (with or without absences), eye closure-induced EEG paroxysms, and photosensitivity. We conducted an open-label trial of levetiracetam in EMA. PATIENTS AND METHODS: Patients were recruited in different Italian Epilepsy Centres. Levetiracetam was administrated at starting dose of 10 mg/kg/day up to 50-60 mg/kg/day in two doses. Treatment period included a 5-6 week up-titration phase and a 12-week evaluation phase. The number of days with EM (i.e., days with seizures, DwS) and number of generalized tonic-clonic seizures (GTCS) were evaluated. Analysis of intent-to-treat population was performed using Fisher's and Wilcoxon tests. RESULTS: Thirty-five patients (23 F) with a mean age of 19 +/- 6 years were recruited. Twenty-seven had previously undergone one to five adequate trials of antiepileptic drugs. The median number of DwS/month was 12 +/- 8.2. Twenty-one patients experienced GTCS (median number/month: 1 +/- 0.2). Thirty-four subjects completed the trial. Levetiracetam was well tolerated (mean dose: 1985 mg/day). Responders were 28/35 (80%) patients, nine taking levetiracetam as monotherapy. Six patients were seizure-free, 15 had > or =75% and seven >50% seizure reduction. GTCS remitted in 14 out of 21 (66.6%) patients. The number/month of DwS (median: 12 vs 5; p = 0.0001) and of GTCS (median: 1 vs 0; p = 0.0001) decreased compared to baseline period. Disappearance or clear reduction in paroxysmal abnormalities at eye closure occurred in 20 of the responders and photoparoxysmal response in 19. Mean follow-up was 23.9 +/- 18.5 months. CONCLUSION: Levetiracetam is effective and well tolerated in EMA. Placebo-controlled studies should confirm these findings.
