Prediction of response to treatment in children with epilepsy

Objective: Predicting the response to treatment in patients treated  with anti-epilepsy drugs are always a major challenge. This study was conducted to predict the response to treatment in patients with epilepsy.Material and Methods: This analytical questionnaire-based study was conducted in 2014 among patients with epilepsy admitted to Mofid Children's Hospital. The inclusion criteria were children 2 months to 12 years of age with epilepsy and patients who experienced fever and seizure attacks at least once were excluded from the study. After the initial recording of patient information, patients were followed up for 6 months and the response to their treatment was recorded. The response to good treatment was defined as the absence of maximum seizure with two drugs during follow up.Result: This study was conducted among 128 children with seizure. 72 patients (56.3%) were boys. The age of the first seizure was under 2 years old in 90 patients (70.3%). History of febrile convulsion, family history of seizure and history of asphyxia was found in 16 patients (12.5%), 41 patients (32%), 27 (21.1%), respectively.  IQ was decreased in 79 patients (61.7%). Seizure etiology was idiopathic in 90 patients (70.3%), and the number of seizures was 1 - 2 in 36 patients (28.1%). 57 patients (44.5%) had cerebral lesion according to CT scan or MRI, and EEG was normal in 21 patients (16.4%) and abnormal in 101 patients (78.9%). In 6-month follow-up, 40 patients (31.3%) responded well to the treatment and 88 patients (68.8%) responded poorly to the treatment. The results of multivariate analysis demonstrated that history of asphyxia (OR = 6.82), neonatal jaundice (OR = 2.81) and abnormal EEG (OR = 0.19) were effective factors in response to treatment.Conclusion: Results of univariate and multivariate analysis indicated that abnormal EEG is an effective factor in treatment response in the children studied
