简要总结
Many families of children with medically refractory epilepsy are choosing to use medicinal cannabinoids (MCBD) as an adjunctive alternative treatment option. The safety, tolerability and efficacy of these products are not known. The primary objective of this study is to determine how the use of MCBD affects children with medically refractory epilepsy in an observational study. Measures of evaluation to be used will include: laboratory values, developmental measures, seizure diaries and serial electroencephalographic (EEG) recordings.
详细描述
This is an observational study of a family's choice to use MCBD and the effect of this substance on medically refractory epilepsy in children. The risks associated with this use are not well known. There have recently been reports of stroke, liver dysfunction and altered anticonvulsant levels. In addition, there have been long term risks reported of decreased memory function, cognitive problems and executive function abnormalities. This study does not condone or advocate the use of the substance but merely seeks to document the short term effects of the use in this population. It should be noted that providers at Children's Hospital Colorado are not registered providers for medicinal cannabis; therefore, this will be an observational study of effects of this substance as prescribed by other physicians outside of our institution.

排除标准

研究组 & 干预措施
Subjects with medically refractory epilepsy
Pediatric epilepsy patients who are followed at Children's Hospital Colorado with medically refractory epilepsy, and whom the family has decided to treat with medical cannabis.
干预措施: Medical Cannabis (Drug)
结局指标
主要结局
Pediatric Epilepsy Side Effects Questionnaire
时间窗: Baseline, 4 weeks, 8 weeks, and 12 weeks
Side effects will be evaluated using PESQ (Pediatric epilepsy Side Effects Questionnaire). This questionnaire will be administered 4 weeks, 8 weeks, and 12 weeks after baseline.
Changes from baseline in background and architecture of seizures confirmed by non-investigational EEG
时间窗: Baseline, 4 weeks, 8 weeks, and 12 weeks
Prolonged EEG recordings lasting 24-48 hours (whichever is clinically indicated) will be performed in either the home setting as an ambulatory EEG or in the hospital in the Epilepsy Monitoring Unit. This decision will be made on a clinical basis. This will allow for objective quantification of seizures in children with frequent seizures that occur on a daily basis and background EEG changes for other children. Two EEGs will be done: one at baseline, and one at the end of the study.
Seizure Frequency
时间窗: Baseline, 4 weeks, 8 weeks, and 12 weeks
Each subject will maintain a seizure diary. Rescue drug use and VNS (Vagus Nerve Stimulation) activations will be tracked as an adjunct to all current anti-seizure medications. Frequency of status epilepticus will be tracked as well as hospital visits for seizures or adverse events from MCBD. Clinical evaluations will be taken every 2 months throughout the duration of the study. Subjects will be monitored every 2 weeks by telephone and/or email.
