What This Study Did, in Plain Language

What Was Tested

Researchers studied CGRP (Calcitonin Gene-Related Peptide) in the context of migraine in this observational study publication.

The aim of this study is to find a relation between several biomarkers in peripheral blood and outcome after treatment with onabotulinumtoxin A (OnabotA).

Why It Was Studied

Different studies have tried to find predictors of response to treatment, either with clinical characteristics, neuroimaging features, or molecular biomarkers; however, it is still not possible to predict the individual outcome.

Who Took Part

The age groups tagged for this paper are adults, middle-aged adults and older adults, both men and women.

The researchers measured serum levels of biomarkers of inflammation (IL-6, IL-10, TNF-α, and hs-CRP), endothelial dysfunction (PTX3 and sTWEAK), blood-brain barrier disruption (cFN), brain damage (S100b, NSE), and trigemino-vascular activation (CGRP) by ELISA in a group of CM patients treated with OnabotA and healthy controls.

How the Study Was Run

The researchers compared baseline levels of biomarkers between these groups.

What Was Measured

Different studies have tried to find predictors of response to treatment, either with clinical characteristics, neuroimaging features, or molecular biomarkers; however, it is still not possible to predict the individual outcome.
