Insights
This study found that vitamin D supplementation, alongside amitriptyline, significantly reduced migraine attacks in children. Even with normal vitamin D levels, adding it to treatment improved outcomes for pediatric migraine patients.
Area of Science:
- Pediatric Neurology
- Nutritional Neuroscience
- Migraine Pathophysiology
Background:
- Migraine is a prevalent neurological disorder in children.
- Vitamin D deficiency is common and may influence neurological conditions.
- Current treatments for pediatric migraine have limitations.
Purpose of the Study:
- To evaluate the efficacy of supplementary vitamin D in pediatric migraine patients receiving amitriptyline.
- To assess the impact of varying vitamin D dosages based on baseline 25-hydroxyvitamin D [25(OH)D] levels.
Main Methods:
- Fifty-three children (8-16 years) with migraine were enrolled and categorized into four groups based on 25(OH)D levels.
- Groups received either amitriptyline alone or amitriptyline plus varying daily doses of vitamin D (400-5000 IU/day) for 6 months.
- Migraine attack frequency and biochemical markers (calcium, phosphorus, etc.) were monitored pre- and post-treatment.
Main Results:
- All vitamin D supplemented groups showed a statistically significant reduction in migraine attacks compared to baseline.
- Groups receiving vitamin D alongside amitriptyline experienced fewer migraine attacks (1.15-2.14 attacks) versus amitriptyline alone (3 attacks).
- No significant changes were observed in calcium, phosphorus, alkaline phosphatase, or parathormone levels across groups.
Conclusions:
- Vitamin D supplementation, when added to amitriptyline, effectively reduces migraine attack frequency in pediatric patients.
- The study suggests a potential therapeutic role for vitamin D in managing pediatric migraine, irrespective of baseline vitamin D status.
- Further research is warranted to optimize vitamin D dosing strategies for migraine management in children.
Abstract:
The purpose of this study was to investigate the effect of supplementary vitamin D therapy in addition to amitriptyline on the frequency of migraine attacks in pediatric migraine patients. Fifty-three children 8-16 years of age and diagnosed with migraine following the International Headache Society 2005 definition, which includes childhood criteria, were enrolled. Patients were classified into four groups on the basis of their 25-hydroxyvitamin D [25(OH)D] levels. Group 1 had normal 25(OH)D levels and received amitriptyline therapy alone; group 2 had normal 25(OH)D levels and received vitamin D supplementation (400 IU/day) plus amitriptyline; group 3 had mildly deficient 25(OH)D levels and received amitriptyline plus vitamin D (800 IU/day); and group 4 had severely deficient 25(OH)D levels and was given amitriptyline plus vitamin D (5000 IU/day). All groups were monitored for 6 months, and the number of migraine attacks before and during treatment was determined. Calcium, phosphorus alkaline phosphatase, parathormone, and 25(OH)D levels were also determined before and during treatment. Results were compared between the groups. Data obtained from the groups were analyzed using one-way analysis of variance. The number of pretreatment attacks in groups 1 to 4 was 7 ± 0.12, 6.8 ± 0.2, 7.3 ± 0.4, and 7.2 ± 0.3 for 6 months, respectively (all P > 0.05). The number of attacks during treatment was 3 ± 0.25, 1.76 ± 0.37 (P < 0.05), 2.14 ± 0.29 (P < 0.05), and 1.15 ± 0.15 (P < 0.05), respectively. No statistically significant differences in calcium, phosphorus, alkaline phosphatase, or parathormone levels were observed (P > 0.05). Vitamin D given in addition to anti-migraine treatment reduced the number of migraine attacks.
