Evaluation of Histamine, CGRP and VIP as Biological Markers for Activation of Trigeminal and Parasympathetic Nerve Fibers in Response to "Sinus" Symptoms

The primary objective of this study is to evaluate histamine, CGRP and VIP levels in saliva as biological markers for activation of trigeminal and parasympathetic nerve fibers in various clinical presentations of primary headaches compared to allergic rhinosinusitis and control populations.

Detailed Description

It has been suggested that many people with self-diagnosed or physician diagnosed "sinus" headache experience symptoms that fulfill diagnostic criteria for migraine or migrainous headache. The shared symptomatology does not differentiate these disorders."Sinus" symptoms as an early manifestation of migraine may be associated with elevated levels of CGRP suggesting peripheral trigeminal activation whereas "sinus" symptoms late in migraine may have associated elevations of VIP suggesting parasymptathetic activation. Subjects without autonomic or "sinus" symptoms will not have changes in salivatory histamine, CGRP or VIP and will have values similar to controls. Subjects with rhinosinusitis will have levels or patterns of salivatory histamine, CGRP and VIP unique from migraine subjects. If "sinus symptoms" are associated with parasympathetic activation, then there should be detectable increases in VIP early in the course of nasal symptom development and, conversely, if these symptoms associate with trigeminal activation, then increases in CGRP should be detected. Five groups of 10 subjects each will be recruited. Group A without migraine, with self-described "sinus" headache or symptoms of rhinosinusitis. Group B with chronic rhinosinusitis and no history of migraine or "sinus" headache. Group C with "sinus" headache with symptoms meeting IHS criteria for migraine and symptoms of rhinosinusitis preceding the onset of headache symptoms meeting migraine criteria. Group D with symptoms of rhinosinusitis that develop late in the course of migraine after criteria for IHS migraine are met. Group E with IHS migraine, without sinus symptoms associated with migraine.
