Objective To explore the efficacy of low to moderate doses of levetiracetam in adult patients with newly diagnosed partial epilepsy and possible predictors for poor treatment response. Methods We retrospectively analyzed the clinical data of patients treated in West China Hospital from March 2011 to December 2015 whose clinical data were input into the Epilepsy database. Patients with newly diagnosed partial epilepsy and whose initial anti-epileptic drug was levetiracetam were screened out for this study. Their clinical data, especially responses to the treatment of levetiracetam were reviewed. Results Ninety-six patients were included in this study. Seventy-one of them achieved seizure-free for a complete year after initial treatment of levetiracetam. Forty-eight patients (50.0%) achieved seizure-free with levetiracetam monotherapy; 23 patients (24.0%) achieved seizure-free for one year with levetiracetam combination therapy. Sixty-nine (97.2%) of the 71 patients achieved seizure-free with low to moderate doses of levetiracetam (500 to 1 500 mg/day), with or without combination of other antiepileptic drugs. High baseline seizure frequency before initial therapy was an independent predictor of poor levetiracetam response in this multivariate logistic regression mode (P=0.019). Conclusions Low to moderate levetiracetam is both effective and well tolerated in newly diagnosed partial epilepsy patients. High baseline seizure frequency before initial therapy is an independent predictor of poor levetiracetam response.
Objective To investigate the diagnosis and treatment of status epilepticus in hospitals of different levels and the knowledge of status epilepticus in clinical physicians, in order to better guide clinical education in the future. Methods From August 2014 to August 2015, a questionnaire was designed and used to investigate the general situation of the hospital, the diagnosis of status epilepticus and the clinical practice among trainee doctors and students in the epilepsy training class in the Neurological Intensive Care Unit and the Department of Neurology of West China Hospital, Sichuan University. The results of the investigation were statistically analyzed. Results Ninety questionnaires were distributed, and all the questionnaires were retrieved with validity. The number of investigated physicians was 42 (46.7%) from the Department of Neurology, 6 (6.7%) from the Department of Neurosurgery, 30 (33.3%) from the Intensive Care Unit and 12 (13.3%) from other departments. Twenty-seven (30.0%) physicians were from class Ⅲ grade A hospitals, 31 (34.4%) from class Ⅲ grade B hospitals, and 32 (35.6%) from class Ⅱ grade A hospitals. All the class Ⅲ hospitals and 53.1% of class Ⅱ hospitals had electroencephalograph monitoring facilities. The proportion of status epilepticus patients ranged from 0.5% to 10.0% in different hospitals. There were great differences in the identification and treatment of convulsive status epilepticus among different hospitals. Conclusions Status epilepticus is a common emergency. Questionnaire survey is an effective means to reflect the difference in identifying and treating the emergency among different departments and hospitals. It can guide clinical education and promote the identification and treatment of the emergency more accurately in doctors of all levels.
