Clinical Trial Summary
The pathophysiological mechanisms that underlie primary headache disorders, such as migraine
and cluster headache (CH), are complex and not yet fully clarified. While there is today
little doubt that activation of the trigeminovascular system (TGVS) is responsible for the
headache pain, the primary mechanisms, probably centrally mediated, leading to its activation
and the generation of pain are still largely obscure. The trigeminal system is supposed to
play a central role not only in migraine but also in cluster headache pathology. In vitro
studies have demonstrated the expression of BDNF in trigeminal ganglion neurons. BDNF release
is induced by trigeminal stimulation and nociceptive inputs. BDNF is a member of the
neurotrophin family and has been recognized as an important modulator of nociceptive
pathways. Interestingly, BDNF is co-expressed with CGRP in trigeminal ganglion neurons. CGRP
is one of the key molecules in migraine and cluster headache pathogenesis. BDNF is an
important marker of neuronal plasticity. It has also been associated with pain processing.
Increased BDNF levels are observed in chronic pain syndromes. In order to understand the role
of BDNF associated with other factors such as gender on headache attacks we aimed to
determine whether migraine and cluster headache is correlated with brain derived neurotrophic
factor (BDNF) level, gender and age.
Description:
Patients will recruite among those attending the Clinic of Tashkent Medical Academy,
Uzbekistan. Three groups of headache patients will be enrolled in this prospective study:
patients with episodic migraine with and without aura, episodic cluster headache, and
frequent episodic tension-type headache according to the current criteria of the
International Headache Society. In migraineurs, venous blood samples will be collected twice:
outside and during migraine attacks prior to pain medication. In cluster headache patients
serum samples will be collected in and outside cluster bout. Analysis of BDNF will performed
using enzyme-linked immunosorbent assay technique. In patients with tension-type headache
(outside attack) and healthy controls, one single blood sample will take.Patients with a
history of cardiovascular disease, major depression, hypertension, drug or alcohol abuse, or
other apparent diseases will be excluded from the study. The research will comprise 120
patients (males and females) suffering from primary headache. At the moment we started
collecting patients.
