Children with atopic dermatitis are as much as six times more likely to develop a food allergy compared to their healthy peers. In regard to food allergens, sensitization rates in patients with atopic dermatitis vary from 30 to 80%, but the clinically relevant food allergy proportions may be lower especially in less-severe phenotypes of atopic dermatitis.34
The relationship between atopic dermatitis and respiratory allergy is influenced by atopic dermatitis severity—while around 20% of children with mild atopic dermatitis develop asthma, over 60% with severe atopic dermatitis develop asthma. Not every patient with atopic dermatitis develops asthma, and not every patient with asthma has preceding atopic dermatitis.
Having a food allergy increases the risk of developing asthma by about 2 times and allergic rhinitis by about 3 times.
Clinical relationship between asthma and allergic rhinitis is well established, with up to three quarters of asthmatics reporting rhinitis symptoms. Allergic rhinitis is also positively correlated with asthma severity, and allergic rhinitis treatment improves asthma control.
