Effect of high dose vitamin d supplementation on vitamin d nutrition status of pre-pubertal children on anti-epileptic drugs – A randomized controlled trial
Clinical Nutrition ESPEN, https://doi.org/10.1016/j.clnesp.2018.11.007

Background and aims
Patients on long term anti-epileptic drug therapy are prone for Vitamin D deficiency for a myriad of reasons. The aim of this research was to study the effect of high dose vitamin D supplementation on vitamin D nutrition status of children newly started on anti-epileptic drug therapy.

This randomized controlled trial was conducted in a tertiary care Children's Hospital at New Delhi from November 2011 to March 2013. Eighty three children in the age group 5–10 years newly started on anti-epileptic drugs (AED) were randomized into two groups; group A – the intervention group, to whom 60,000 IU vitamin D3 was given orally/month under direct supervision along with AED for a period of 6 months, and group B- the control group, to whom AED without vitamin D3 was given. Serum 25(OH)D, ionized calcium (iCa), total calcium (tCa), inorganic phosphate (iP), alkaline phosphatase (ALP) and parathyroid hormone (PTH) levels were assayed at baseline and at the end of 6 months and were compared within and between the two groups.

The mean 25(OH)D in Group A was maintained at 6 months follow up [ 26 ng/ml, 95% CI 20–34 ng/ml] compared to baseline [25 ng/ml, 95% CI −19 to 33 ng/ml] [ p = 0.83]. In group B, there was a significant decrease in 25(OH)D levels at 6 months [13 ng/ml (95% CI 9 ng/ml–17 ng/ml)] compared to baseline [18 ng/ml (95% CI 13–24 ng/ml)] [p = 0.01]. At 6 months, mean serum 25(OH)D was significantly higher in group A as compared to group B (p = 0.005).

Conclusion: To conclude, oral administration of 60,000 IU vitamin D3/month is sufficient to maintain serum 25(OH)D level and prevent development of vitamin D deficiency in children newly started on AED over a period of 6 months. Non supplementation leads to the lowering of serum 25(OH)D in these children.

The impact of antiepileptics on serum vitamin levels is controversial and uncertain. With no clear conclusions on the impact of antiepileptics on serum levels of vitamins, there is a need for further clinical studies in order to ascertain the impact of old and newer antiepileptic drugs on serum levels of vitamins in epileptic patients, thus accomplishing a suitable usage of vitamins supplementation.

The intention of the present research is to confirm the hypothesis of whether or not vitamin levels are altered with antiepileptic drugs. The study also aims to reveal which vitamin levels are particularly more altered, are vitamin levels affected by gender and the type and number of antiepileptics used.

The present research was piloted in collaboration with the Department of Neurology in Qilu Hospital of Shandong University. A total of 63 serum samples of epileptic patients receiving antiepileptics as monotherapy or polytherapy were requested for analysis of nine vitamin serum levels. Total nine vitamins (B1, B2, B6, B9, B12, A, C, D and E) in epileptic patients receiving antiepileptic drugs were analyzed. The serum results of all vitamins were compiled and evaluated with SPSS.

It was alarmingly found that serum levels of vitamin D were particularly very low in almost all (90%) epileptic patients in this study. Notably, serum levels of vitamin C and vitamin B1 were also below reference range in 72% and 46% epileptic patients, respectively. The remaining vitamins were almost in reference range for most of the patients. In our study, mean and frequency of vitamin D, C and B1 levels do not vary too much among different gender groups. The patients receiving newer antiepileptic drugs displayed a slightly increased serum vitamin D levels in comparison to the patients receiving older antiepileptic drugs. We found low vitamin D, C and B1 serum levels in patients who were on monotherapy as in comparison with patients on polytherapy.

The most significant and surprising finding of this study revealed that serum vitamin D levels in particular were very low in almost all patients and in some patients vitamin B1 serum levels were also below the reference range. More importantly, it is first time reported here that vitamin C serum levels were also below reference range in the majority of these Chinese epileptic patients. It is recommended that all these vitamins should be regularly monitored in addition to therapeutic drug monitoring of antiepileptic drugs. Additional clinical trials are required for further evaluation. It is also recommended that epileptic patients with low serum levels of these vitamins may be prescribed vitamins supplementations with antiepileptic drugs in order to control their seizures more effectively and efficiently.

Vitamin D deficiency is not only associated with the adverse effects of chronic treatment with antiepileptic drugs (AEDs), but also with epilepsy. Although emerging evidence suggests that AEDs can accelerate the vitamin D catabolism, resulting in suboptimal vitamin D status, there are a limited number of studies examining the vitamin D status in epileptic patients, especially in first-episode or AEDs-naïve children.
Determined with high-performance liquid chromatography-tandem mass spectrometry, circulating 25(OH)D3 and 24,25(OH)2D3 levels, and 24,25(OH)2D3:25(OH)D3 ratio were compared between AEDs-treated epileptic (n = 363) and control (n = 159) children. To further figure out whether the patients were in a vitamin D deficient prone state even before treatment, epileptic children before their initiation of treatment (n = 51) were enrolled into a follow-up study.
A significant decrease of 25(OH)D3 and 24,25(OH)2D3 levels, but a significant increase of 24,25(OH)2D3:25(OH)D3 ratio was observed in epileptic children, compared with controls. Baseline 25(OH)D3, 24,25(OH)2D3 and 24,25(OH)2D3:25(OH)D3 ratio in the follow-up group were similar to those in controls, but significantly changed with 2 months of AED therapy.
Disturbed vitamin D levels were possibly the consequence of AED therapy, rather than the contributing factor of epilepsy. Collectively, circulating vitamin D levels should be monitored and corrected in AEDs-treated epileptic children.

Epilepsy appears to be treated by Vitamin D (starting 5,000 IU RCT) – Dec 2016

Vitamin D for the Treatment of Epilepsy: Basic Mechanisms, Animal Models and Clinical Trials

There is increasing evidence supporting dietary and alternative therapies for epilepsy, including the ketogenic diet, modified Atkins diet, and omega-3 fatty acids. Vitamin D is actively under investigation as a potential intervention for epilepsy. Vitamin D is fat soluble steroid which shows promise in animal models of epilepsy. Basic research has shed light on the possible mechanisms by which Vitamin D may reduce seizures, and animal data support the efficacy of Vitamin D in rat and mouse models of epilepsy. Very little clinical data exists to support the treatment of human epilepsy with Vitamin D, but positive findings from preliminary clinical trials warrant larger Phase I and II clinical trials in order to more rigorously determine the potential therapeutic value of Vitamin D as a treatment for human epilepsy.

From the end of the conclusion section
"Recently, our group has received an IND for a Phase I study of Vitamin D3 in drug-resistant epilepsy to study the safety, preliminary efficacy and potential cardiac benefits of Vitamin D3 5000 IU/day in drug-resistant epilepsy."

Vitamin D Life Summary

14 ng for newly diagnosed vs 23 ng for controls
Suspect that newly diagnosed have not had Vitamin D depleting drugs


  • Vitamin D appears to treat Epilepsy, and might prevent Epilepsy
  • Vitamin D is depleted by many epileptic drugs
  • People with Epilepsy should take vitamin D so as to avoid having health problems associated with low vitamin D, such as low bone density

Several studies have shown a link between vitamin D deficiency and epilepsy. This study includes 60 newly diagnosed idiopathic epilepsy patients and 101 healthy controls (between the ages of 5 and 16). Each group was also divided into two subgroups according to seasonal changes in terms of months of longer versus shorter daylight. We retrospectively evaluated the levels of calcium, phosphorus, alkaline phosphatase, parathyroid hormone, and 25-OH vitamin-D3 in the study participants. Levels below 20 ng/ml were defined as vitamin D deficiency and levels of 20-30 ng/ml as insufficiency. There were no significant differences in age, gender distribution and levels of calcium, phosphorus, alkaline phosphatase and parathyroid hormone between the groups. The level of 25-OH vitamin-D3 in the patient group was significantly lower when compared to the control group (p < 0.05) (14.07 ± 8.12 and 23.38 ± 12.80 ng/ml, respectively). This difference also held true when evaluation was made according to seasonal evaluation (12.38 ± 6.53 and 17.64 ± 1.14 in shorter daylight and 18.71 ± 9.87 and 30.82 ± 1.04 in longer daylight).

Idiopathic Epilepsy at AboutKidsHealth

There are a variety of idiopathic epilepsy syndromes. Children with idiopathic epilepsy may have generalized or partial seizures.
Many, although not all, idiopathic epilepsy syndromes are benign and the child will eventually grow out of them.
Relatives of a child with idiopathic epilepsy often have a history of seizures.
What are other terms for idiopathic epilepsy?
An older term for idiopathic epilepsy is primary epilepsy. The terms “idiopathic epilepsy” and “cryptogenic epilepsy” are sometimes used interchangeably, especially in older books and articles.
What causes idiopathic epilepsy?
By definition, there is no apparent underlying cause of idiopathic epilepsy, such as a structural problem with the brain or a metabolic disorder. It is possible that idiopathic epilepsy is caused by tiny abnormalities at the cellular level. We are now learning that many, although not all, idiopathic epilepsy syndromes have an associated genetic component.
In most cases, the exact way in which epilepsy is inherited is unclear. However, some researchers estimate that genes could account for 70% to 90% of the tendency to develop epilepsy.
What epilepsy syndromes are idiopathic?

  • benign epilepsy of childhood with centrotemporal spikes (BECTS)
  • childhood epilepsy with occipital paroxysms
  • benign neonatal familial convulsions
  • benign neonatal convulsions
  • benign myoclonic epilepsy in infancy
  • childhood absence epilepsy
  • juvenile absence epilepsy
  • juvenile myoclonic epilepsy

How many other children have idiopathic epilepsy?
Idiopathic epilepsy is common; about 30% of childhood epilepsy is idiopathic.
Together, idiopathic and cryptogenic epilepsy account for 55% to 75% of cases of childhood epilepsy.
It is difficult to be precise, because different researchers define these terms differently.
How is idiopathic epilepsy treated?
Idiopathic epilepsy is treated with anti-epileptic drugs.
What is the outlook for a child with idiopathic epilepsy?
The outlook for a child with idiopathic epilepsy depends on the specific condition and how well the seizures respond to treatment.
Several idiopathic epilepsy syndromes, such as childhood absence epilepsy and BECTS, usually go away on their own.
With other syndromes, though, the child may need to take anti-epileptic drugs all his life.
Elizabeth J. Donner, MD, FRCPC, 2/4/2010

About one percent of Americans have some form of epilepsy, and nearly four percent (1 in 26) will develop epilepsy at some point in their lives. The number of Americans who have epilepsy is greater than the number who have multiple sclerosis, Parkinson's disease, and cerebral palsy combined.
