Migraine Headache in A Child with House Dust and Mite Allergy

Background: House dust mite is common aeroallergen. It can cause type 1 allergy (IgE-mediated) symptoms from dust inhalation with different spectrums of the disease. The relationship between migraine headache and aeroallergen has been questioned for many years. Objective: To report a case of migraine headaches in a child due to house dust and mite allergy and the course of this allergy after specific immunotherapy. Methods: Case report; routine skin testing and laboratory tests. Results: A 9-year-old boy with a 2-years history of migraine headaches every morning especially in the rainy season. Skin tests revealed positive reactions to commercial house dust extract, mite extract and Der p 1 extracts. An elevated total IgE level and specific house dust and mite IgE RAST found in the serum of patient. After 3 months of initial immunotherapy the symptoms decreased significantly. Conclusions: This case reported the rare case of childhood migraine headache due to house dust and mite allergy. This report demonstrates that without immunotherapy, a migraine headache did not yield symptoms improvement.
