Relationship between age and vitamin E level in epileptic and normal children
Insights
Children on anticonvulsant medications show lower plasma vitamin E levels compared to healthy children. This deficiency may be linked to the metabolic effects of epilepsy drug therapy, impacting normal vitamin E development.
Area of Science:
- Pediatric Neurology
- Clinical Biochemistry
- Pharmacology
Background:
- Anticonvulsant drugs are commonly prescribed for epilepsy in children.
- Vitamin E is a crucial fat-soluble antioxidant with potential neuroprotective roles.
- Previous studies suggest a possible link between anticonvulsant therapy and altered vitamin E status.
Purpose of the Study:
- To investigate plasma vitamin E levels in children treated with anticonvulsants.
- To compare vitamin E levels between epileptic children and a healthy control group.
- To explore potential age-related patterns in vitamin E levels within these groups.
Main Methods:
- Assay of plasma vitamin E levels.
- Recruitment of 100 children on anticonvulsants (single or combination therapy).
- Recruitment of 100 age-matched healthy children as controls (ages 2-12 years).
Main Results:
- Children on anticonvulsants exhibited significantly lower plasma vitamin E levels compared to controls.
- Even control children had lower plasma vitamin E levels than published adult values.
- The typical age-related increase in vitamin E levels was not observed in the epileptic children group.
Conclusions:
- Anticonvulsant therapy in children may lead to reduced plasma vitamin E concentrations.
- The metabolic effects of anticonvulsants could interfere with normal vitamin E development and utilization.
- Further research is warranted to understand the clinical implications and potential interventions for vitamin E deficiency in epileptic children.
Abstract:
Plasma vitamin E was assayed in 100 children on anticonvulsants either singly or in combination. Their plasma vitamin E levels were lower than in 100 apparently normal children. The age range of the children was between 2 and 12 years. The plasma vitamin E levels of the control children were lower than published values for adults. In the normal course of development, vitamin E levels increase with age but this developmental pattern does not occur in groups of epileptic children, and this may be related to the metabolic effects of drug therapy in epilepsy.
