A. Pradalier et al., IMMUNOCYTE ENUMERATION IN DUODENAL BIOPSIES OF MIGRAINE WITHOUT AURA PATIENTS WITH OR WITHOUT FOOD-INDUCED MIGRAINE, Cephalalgia, 14(5), 1994, pp. 365-367
The possibility of an IgE-mediated allergic mechanism in food-induced
migraine remains controversial. Twenty consecutive migraine patients,
II with food-induced migraine, 9 without, were investigated for determ
ination and counting of immunocyte populations (IgA, IgM, IgE, IgG con
taining cells) by biopsies at duodenum 2 level. Conventional histology
and plasmocyte populations were not significantly different between t
he two groups of migraine patients. This study does not support the ex
istence of an IgE-mediated allergic mechanism in food-induced migraine
.
