Atopy is more prevalent among older children and young asthmatic adults. Atopy is inherited, but the pattern of inheritance is not well defined. Total IgE is increased in atopy. High IgE in early infancy may predict the development of allergic illnesses, including asthma. Sensitization to allergens and repeated exposure are the triggers of developing asthma in atopic patients. Allergic rhinitis patients without asthma are known to have increased bronchial reactivity. Allergy is a risk factor in occupational asthma and in exercise-induced asthma. Environmental control and allergen avoidance are advisable for the well-being of many asthmatics. More elaborate studies are required to find if allergen avoidance in infancy will help to prevent the development or change the course of atopic diseases. Hyposensitization may help control asthma in allergic patients.
