Comorbidités de la dermatite atopique: Comorbidities of atopic dermatitis.

ABSTRACT

Atopic dermatitis is associated with an increased risk of asthma (10 to 30% according to age), allergic rhinitis and conjunctivitis and food allergy. Other comorbidiies are globally lest frequent than in psoriasis. There is no increased risk of solid cancer. Smoking is a major confounding factor that has to be taken into account. Obesity and metabolic syndrome are more frequent and there is a moderately increased cardiovascular risk in severe forms of atopic dermatitis. There is a clear-cut increased risk of vitiligo and alopecia areata and a lower risk of other auto-immune diseases, including type I diabetes in children. There is a higher risk of cutaneous but not extra-cutaneous bacterial and viral infections, and increased frequency of contact dermatitis and urticaria. Severe atopic dermatitis is associated with psychiatric comorbidities, like attention disorders/hyperactivity, depression and suicidal ideas. © 2019 Elsevier Masson SAS. All rights reserved.
