Insights
Carnitine deficiency is common in children with epilepsy. Using valproate with other antiepileptic drugs (AEDs) is the primary risk factor identified in this study.
Area of Science:
- Pediatric Neurology
- Clinical Chemistry
Background:
- Carnitine deficiency is prevalent in epileptic patients.
- Risk factors include polytherapy with antiepileptic drugs (AEDs), young age, and neurological impairments.
Purpose of the Study:
- To investigate carnitine deficiency levels and associated risk factors in children with idiopathic epilepsy on various AEDs.
Main Methods:
- Serum carnitine levels were measured using enzyme-linked immune sorbent assay (ELISA).
- Fifty children with idiopathic epilepsy and 40 age-matched controls were included.
Main Results:
- Epileptic children exhibited lower mean carnitine levels than controls (p=0.04).
- Patients on valproate combined with other AEDs showed significantly lower carnitine levels (p=0.03).
- Monotherapy also correlated with a high percentage of carnitine deficiency (p=0.04).
Conclusions:
- Carnitine deficiency is a common issue in the studied pediatric epilepsy population.
- Concurrent use of valproate and other AEDs is the most significant risk factor for carnitine deficiency in epileptic children.
Background:
Carnitine deficiency is relatively common in epileptic patients. The risk factors reported include the combination of valproic acid with other antiepileptic drugs (AEDs), young age, multiple neurologic disabilities, non-ambulatory status, and being underweight.
Objectives:
To study the level of carnitine deficiency and its associated risk factors among a group of children with idiopathic epilepsy treated with different AEDs.
Patients And Methods:
Fifty children with idiopathic epilepsy and 40 age-matched controls were enrolled. For all, serum carnitine level was measured by enzyme-linked immune sorbent assay (ELISA).
Results:
The mean carnitine level was lower in cases compared to controls (p = 0.04). Patients receiving monotherapy treatment had a high percentage of carnitine deficiency compared to controls (p = 0.04). Patients receiving valproate with other AEDs had a lower level of carnitine compared to controls (p = 0.03). The age of the patients, the duration of treatment, and the doses of different AEDs were not risk factors for carnitine deficiency.
Conclusions:
Carnitine deficiency is common in our population, and the use of valproate with other AEDs is considered the most important risk factor for it in epileptic children.
