Objectives

Narrative objectives1

Iron deficiency has been attracting attention as a possible modifying factor involved in the pathology of migraine, and its comorbidity has been reported, especially in young women. Neuroimaging studies have suggested abnormalities in intracerebral iron deposition in migraine patients, and abnormal iron metabolism may affect migraine susceptibility and treatment response. However, accurate clinical assessment of iron deficiency is difficult because the diagnostic criteria for iron deficiency are not unified and the prevalence varies greatly depending on the evaluation method. In recent years, the introduction of CGRP-targeted drugs has made great progress in preventive treatment of migraine, but there are still cases in which sufficient efficacy is not achieved. Iron deficiency is common and can be improved by appropriate intervention, so it is clinically important as a potential intervention target that can improve treatment response. In this study, we will clarify the prevalence of iron deficiency in migraine patients based on standard diagnostic criteria and examine whether iron supplementation therapy can complement the preventive treatment effect. We will also evaluate the usefulness of iron supplementation monotherapy in pregnant and lactating patients and consider the importance of iron supplementation therapy in migraine treatment.

Assessment

Primary outcomes

Prevalence of iron deficiency in migraine patients (assessed based on hemoglobin [Hb], serum iron [Fe], total iron-binding capacity [TIBC], transferrin saturation [TSAT: calculated as Fe/TIBC], and serum ferritin)

Key secondary outcomes

Clinical usefulness of iron supplementation therapy (improvement in MHD, HIT-6, and MIBS-4), and efficacy of iron monotherapy during pregnancy and lactation

Primary endpoint: To determine the prevalence of iron deficiency in migraine patients, and to evaluate diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated. Iron deficiency was classified into the following four groups based on five indices: Hb, Fe, TIBC, TSAT, and ferritin. Normal iron status: all indices within the reference range. Functional iron deficiency: TSAT<20%, Hb and ferritin normal. Storage iron deficiency: low ferritin (women < 30 ng/mL, men < 50 ng/mL), Hb normal. Iron deficiency anemia (IDA): Hb below gender-specific norm (women<12.0 g/dL, men<13.0 g/dL) and accompanied by Fe<50 ug/dL, TIBC>400 ug/dL, TSAT<20%, or low ferritin. Comparison between two groups: t-test or Mann-Whitney U test was used for continuous variables, and chi-square test or Fisher's exact test was used for categorical variables. The significance level was set at p<0.05 (two-sided test).
