摘要
Objectives: This study aimed to test the hypothesis that high-dose prednisolone (4 mg/kg/day) may be more efficacious than usual-dose (2 mg/kg/day) prednisolone for spasm resolution at 14-days in children with infantile spasms. Methods: This was a randomized, open-label-trial conducted at a tertiary-level-hospital from February-2012 to March-2013. Children aged 3-months to 2-years presenting with infantile spasms in clusters (at least 1 cluster/day) with hypsarrhythmia or its variants on EEG were enrolled. The study participants were randomized to receive either high-dose prednisolone (4 mg/kg/day) or the usual-dose (2 mg/kg/day) prednisolone. The primary outcome measure was the proportion of children who achieved spasm freedom for 48-h at day-14 after treatment initiation as per parental reports in both the groups. The adverse effects were also monitored. The study was registered with the clinicaltrials.gov (ClinicalTrials.gov Identifier: NCT01575639). Results: Sixty-three children were randomized into the two groups with comparable baseline characteristics. The proportion of children with spasm cessation on day-14 was significantly higher in the high-dose group as compared to the usual-dose group (51.6% vs. 25%, p = 0.03). The absolute risk reduction was 26.6% (95% confidence interval 11.5-41.7%) with number needed to treat being 4. The adverse effects were comparable in both the groups. Conclusions: High-dose prednisolone (4 mg/kg/d) was more effective than low-dose prednisolone (2 mg/kg/d) in achieving spasm cessation at 14-days (as per parental reports) in children with infantile spasms.
