title: A clinical, radiological and outcome study of status epilepticus from India.
abstract: The objective of this study is to evaluate the clinical and radiological characteristics and the outcome of status epilepticus (SE). 117 consecutive patients with SE were evaluated including their demographics, history of epilepsy, antiepileptic drug (AED) default, comorbidities, SE type and duration. The study included 22 children, 77 adults and 18 elderly patients with SE. Blood counts, serum chemistry, ECG, cranial MRI, cerebrospinal fluid and EEG were done. Patients were treated with IV phenytoin, valproate, lorazepam or diazepam as per a fixed protocol and responses to first and second drugs were noted. Death during hospital was recorded. The etiology of SE was infection in 53.8%, drug default in 7.9%, metabolic in 14.5%, stroke in 12.8% and miscellaneous in 11% of patients. 92.3% of patients had convulsive and 7.7% nonconvulsive SE. Cranial MRI was abnormal in 62%. Infection as an etiology was more common in children, drug default and metabolic causes in adults and stroke in adults and elderly. Following first AED, SE was controlled in 50%. 30% of patients remained refractory to second AED which was related to duration of SE and mortality. 29% patients died and death was higher in elderly (44%) compared to children (14%). Acute symptomatic SE is more common in developing countries. Refractory SE is associated with SE duration and mortality.
