Abstract
OBJECTIVE
This study aimed to evaluate the impact of prolonged sodium valproate use on bone mineral density (BMD) and Vitamin D levels in pediatric epilepsy patients.
METHODS
In a cross-sectional study conducted at the Epilepsy Clinic of Niloufer Hospital, Hyderabad, India, 50 pediatric patients (aged 4-10 years) were recruited. The cohort comprised 30 epilepsy patients on sodium valproate treatment (cases) and 20 healthy siblings without epilepsy or valproate use (controls). BMD was assessed using dual-energy X-ray absorptiometry to measure height-adjusted total body less head Z-scores (TBLH Z-scores), and serum 25-hydroxyvitamin D levels were measured. Statistical analysis included independent samples t-tests, Mann-Whitney U tests, and Pearson correlation, with a preliminary power analysis ensuring adequate sample size.
RESULTS
Cases exhibited significantly lower BMD TBLH Z-scores (Mean = -1.543) compared to controls (Mean = 0.515, p <.001) and reduced Vitamin D levels (Mean = 9.17 for cases vs. 27.80 for controls, p <.001). A negative correlation was observed between the duration of sodium valproate use and both BMD Z-scores (r = -0.626, p <.001) and Vitamin D levels (r = -0.707, p <.001).
CONCLUSIONS
The findings suggest a significant negative impact of prolonged sodium valproate use on both bone density and Vitamin D levels in pediatric patients. These results underscore the importance of monitoring and managing bone health in children receiving long-term sodium valproate therapy.
