Abstract
OBJECTIVES
To compare the change in serum vitamin D levels and to compare the changes in serum levels of calcium, phosphate, alkaline phosphatase and parathyroid hormone in vitamin D supplemented and unsupplemented groups after 3 mo.
METHODS
In this randomized, parallel group, nonblinded, controlled trial, 40 children, 2-12 y of age with newly diagnosed epilepsy, and vitamin D sufficient status, and started on valproate monotherapy, were randomized into the intervention group (n = 20), which was given daily oral 600 IU vitamin D supplementation, and the control group (n = 20), which was not given any supplementation. Changes in the biochemical parameters was measured in the two groups after 3 mo.
RESULTS
There was a significant reduction in the median (IQR) vitamin D levels in the control group as compared to an increase seen in the intervention group [-6.64 (-8.4, -2.65) vs. 5.66 (1.81, 7.12); p < 0.001]. In the control group, 37.5% children developed vitamin D insufficiency and 12.5% developed deficiency whereas only 5% of the intervention group developed vitamin D insufficiency (p = 0.005). There was a significant decrease in ionized calcium (p = 0.02), increase in serum phosphate (p = 0.02), and alkaline phosphatase level (p = 0.003) in the unsupplemented group as compared to the supplemented group.
CONCLUSION
Vitamin D supplementation can reduce the valproate-associated decline in vitamin D levels and the negative impact on other markers of bone mineral metabolism.
