Protocol summary

Study aim
To determine the effects of vitamin D compared to placebo on CGRP levels, inflammatory markers, Treg/Th17 balance and episodic migraine characteristics in Adults migraine
Design
The present study will be conducted as a 16-week phase 1 randomized double-blind placebo-controlled trial on 80 episodic migraineurs allocated in 2 parallel groups each consisted of 40 episodic migraine patients who will receive vitamin D or placebo. From the beginning of the study, A and B codes are available to researchers to recruit the patients using twenty 4-Block Randomizations.
Settings and conduct
The study will perform at the tertiary headache clinic of Sina University Hospital. Information on demographic data and headache characteristics will be collected. A blood sample will be taken at 8 cc. Patients will be randomized to either the intervention or placebo group at the beginning of the fifth week for 12 weeks.
Participants/Inclusion and exclusion criteria
episodic migraine patients according to ICHDIII criteria aged 18 to 45 years
Intervention groups
Patients in the intervention group will receive 1 capsule containing 2,000 IU of vitamin D per day in addition to routine medications prescribed by our study neurologist. While the placebo group will receive 1 placebo capsule which will be indistinguishable from vitamin D capsules in taste and appearance. Patients will be asked to not change their medications during the study.
Main outcome variables
headache attack frequency per month; headache severity (VAS); attack duration (min per month)

Blinding (investigator's opinion)
Double blinded
Blinding description
Only one of the staff of the headache department is aware of the type of assigned intervention for each patient (vitamin D or placebo, which are marked by A or B codes). Finally, after collecting the data, she unseals the codes for researchers, the statistical analyst, and those who prepare the manuscript.
