  • Title: Proinflammatory cytokines in cervicogenic headache.
    Author: Martelletti P, Stirparo G, Giacovazzo M.
    Journal: Funct Neurol; 1999; 14(3):159-62. PubMed ID: 10568217.
    Abstract:
    Interleukin-1 beta (IL-1 beta) and Tumour Necrosis Factor-alpha (TNF-alpha) exert their multifunctional biological effect by promoting and increasing the molecular events of cellular inflammation. The aim of this study was to find out whether the cytokine pattern of cervicogenic headache (CH) patients tends, like that seen in cluster headache, towards an inflammatory status. Fifteen CH patients, diagnosed according to the 1998 CHISG criteria, were analysed for serum IL-beta (ELISA) and TNF-alpha (bioassay and ELISA) both during the natural course of a painful attack and during a phase of mechanically worsened pain. The control groups consisted of 15 migraine without aura (MWA) patients and 15 historically healthy subjects. The MWA patients were studied both during (MWA-IN) and outside (MWA-OUT) a migraine attack. Higher levels of both IL-1 beta and TNF-alpha were detected in the sera of CH patients than in that of MWA-IN and MWA-OUT and C subjects. A difference also emerged in CH between spontaneous and mechanically worsened pain phases. We conclude that the degree of cytokine production may depend on the different pathophysiological mechanisms at work in MWA and CH.
