Official title
Investigating the inFluence of EndoMetriosis IN migraINE - FEMININE Study
Overview
Migraine and endometriosis are common conditions that mainly affect females of reproductive age. Both can cause significant pain and have a strong impact on the quality of life. Increasing evidence suggests that these two conditions often occur together, and that females who have both may experience more severe symptoms than those with only one of them. However, the reasons why migraine and endometriosis are linked are still not well understood. Some biological factors may help explain this connection. One of them is a molecule called calcitonin gene-related peptide (CGRP), which plays an important role in migraine and may also be involved in pain and inflammation in endometriosis. In addition, hormonal changes during the menstrual cycle, especially fluctuations in estrogen levels, may influence symptoms in both conditions. Genetic and epigenetic factors may also contribute to this association. The main hypothesis of this study is that females who have both migraine and endometriosis have a distinct clinical and biological profile compared to females who have only migraine or only endometriosis. In particular, it is expected that differences will be observed in CGRP levels and hormonal patterns across the menstrual cycle. The FEMININE study is a prospective observational study that will follow females over several menstrual cycles. It will include three groups: females with both migraine and endometriosis, females with migraine only, and females with endometriosis only. Participants will record their symptoms in diaries and will provide blood samples at specific times of the menstrual cycle. The main goal of the study is to compare CGRP levels between groups. Additional goals include describing differences in symptoms, menstrual-related migraine, hormonal levels, and selected genetic and epigenetic markers. By improving the understanding of how migraine and endometriosis are related, this study aims to support better diagnosis and more personalized care for females affected by these conditions.
