Background: The frequency of atopy in women with premenstrual asthma (PMA) and its possible effect on the premenstrual exacerbation of asthma are unknown.
Objective: To analyze the relation between atopy markers (total IgE, Phadiatop, and specific IgE) and PMA.
Methods: Asthmatic women of reproductive age completed a questionnaire about respiratory symptoms and recorded peak flow during an entire menstrual cycle to be classified as asthmatic patients with or without PMA.
