Salivary CGRP can monitor the different migraine phases: CGRP (in)dependent attacks

What Was Tested

The paper reports a study of CGRP (Calcitonin Gene-Related Peptide) in the context of migraine, published as an observational study.

To assess saliva as a substrate to measure CGRP by comparing interictal levels in patients with episodic migraine and controls; and to evaluate CGRP's temporal profile during migraine attacks.

Why It Was Studied

CGRP plays a key role in the transmission and modulation of nociceptive signals and is a critical component in the pathogenesis of migraine.

Who Took Part

PubMed tags the participants as women only.

This prospective observational pilot study included young women with episodic migraine and healthy controls.

How the Study Was Run

The researchers set it up as a pilot study.

It is described as a pilot, a small early test of whether a larger CGRP (Calcitonin Gene-Related Peptide) study would be practical.

The researchers monitored salivary CGRP-like immunoreactivity (CGRP-LI) during 30 consecutive days and during migraine attacks.

The researchers considered six timepoints for the analysis: interictal (72h headache free), preictal (PRE-24h before the attack), ictal (headache onset, after 2h, after 8h), postictal (POST-24h after the attack).

CGRP levels were quantified by ELISA.
