title: Efficacy and tolerability of high-dose prednisone in Chinese children with infantile spasms.
abstract: OBJECTIVE
  The aim of this study is to preliminarily evaluate the clinical efficacy and safety of high-dose prednisone in the treatment of infantile spasms (IS) in China, and to provide additional choice of the therapy of IS.
  
  
  METHODS
  Twenty patients aged 3-53 months with IS were collected in the Department of Neurology of Jiangxi Children's Hospital from May in 2011 to December in 2012, who were placed on high-dose prednisone (took prednisone tablet of 10mg four times a day) for 2 weeks during admission to our hospital. The assessment of spasms seizure and video-EEG monitoring were preformed before treatment and after 2 weeks and the end of treatment of the regimen (7 weeks), respectively. All of the children were followed-up for 2-14 months.
  
  
  RESULTS
  Among 20 cases, there were 16 cases (80.0%) with complete cessation of spasms after 2 weeks and 13 cases (65.0%) after 7 weeks. There were 19 cases with typical or modified hypsarrhythmia in 20 cases. No matter after 2 or 7 weeks, there were 12 cases showed complete resolution of hypsarrhythmia and 7 cases with only a partial remission of hypsarrhythmia. After a follow-up of 2-14 months, the longest spasm-free interval was 14 months and the shortest one was 11 days. Six cases relapsed in different periods, and the relapse rate was 35.3%. Amongst the main adverse events, there were Cushing's symptoms in 15 cases (75.0%), irritability in 8 cases (40.0%), drosiness in 3 cases (15.0%), high blood pressure in 3 cases (15.0%), and infections in 8 cases (40.0%), but no one stopped the treatment because of the adverse reactions.
  
  
  CONCLUSIONS
  In total, high-dose prednisone was effective and well-tolerated in children with IS in China. Maybe the regimen will become a new choice in the treatment of IS.
