Insights
Children with epilepsy show reduced physical growth, potentially due to hormonal imbalances affecting growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels. This study investigated these effects in pediatric patients on anti-epileptic drugs.
Area of Science:
- Pediatric Endocrinology
- Neurology
- Growth and Development
Background:
- Epilepsy and anti-epileptic drugs (AEDs) can disrupt hormonal balance.
- Previous studies noted growth disturbances in epileptic patients.
- The impact of epilepsy and AEDs on growth hormone (GH) and insulin-like growth factor-1 (IGF-1) requires further evaluation.
Purpose of the Study:
- To assess the effect of idiopathic epilepsy and AEDs on physical growth.
- To evaluate GH and IGF-1 status in children and adolescents with epilepsy.
- To compare growth parameters and hormonal levels between epileptic patients and a control group.
Main Methods:
- Studied 40 children/adolescents with idiopathic epilepsy on valproate or carbamazepine.
- Performed anthropometric measurements including height and body mass index (BMI).
- Assessed serum GH (pre- and post-L-dopa provocation) and IGF-1 levels, comparing to a matched control group.
Main Results:
- Epileptic patients exhibited reduced height and significantly higher BMI compared to controls, particularly those on valproate.
- Post-provocation GH and IGF-1 levels were significantly lower in patients.
- Epilepsy type, duration, and seizure control did not significantly affect studied parameters.
Conclusions:
- Epilepsy and/or AEDs appear to negatively impact physical growth in children.
- Reduced post-provocation GH and IGF-1 levels suggest hormonal imbalance as a contributing factor.
- Further research into managing growth and hormonal status in epileptic children is warranted.
Background:
Patients with epilepsy often complain of symptoms that may be caused by disturbances in their hormonal balance. Disturbances in physical growth has been previously described. The aim of this study was to evaluate the effect of epilepsy and/or anti-epileptic drugs on the physical growth of patients with idiopathic epilepsy, as well as on the growth hormone (GH) and insulin growth factor-1 (IGF-1) status in those patients.
Methods:
The study comprised 40 children and adolescents with idiopathic epilepsy on either valproate or carbamazepine. Anthropometric measurements [occipitofrontal circumference, weight, height, body mass index, span, and midarm circumference] were taken. Serum levels of GH before and after provocation with L-dopa and of IGF-1 were assessed. Results were compared to a matched control group.
Results:
The height measurements were reduced in patients with epilepsy compared to the controls group. Though weight values were not significantly different, the body mass indices of the patients were significantly higher than controls, especially in patients on valproate therapy. Basal GH levels showed no significantly variation between patients and controls. However, post provocation GH and IGF-1 levels were significantly lower in patients. The type of epilepsy, disease duration, and the degree of seizure control had no significant effect on the studied parameters. In conclusion, physical growth seems to be affected in patients with epilepsy. This may be due to hormonal imbalance as evident by reduced post provocation GH levels and IGF-1 levels in the included group of patients.
