The Atopic March: From Skin to the Airways
,
Abstract
Many patients with atopic eczema (AE) would “march” to develop allergic rhinitis (AR) and asthma. Physicians, patients and their families often do not appreciate the significance of these diseases as co-morbidities of atopy.
The aim of this study was to evaluate the prevalence and severity of airway atopies in patients with AE. AR and asthma severity were assessed in consecutive AE patients seen at a pediatric dermatology clinic by ARS (allergic rhinitis score) and ACT (asthma control test). Eczema severity (SCORAD and Nottingham Eczema Severity Score: NESS) were recorded.
110 patients with AE and 42 patients without AE were recruited. Allergic rhinitis and asthma were significantly more prevalent in patients with AE [odds ratio for AR was 2.9 (CI:1.3 – 6.5) and for asthma 4.3 (CI: 1.3 – 16.10)]. 23 (45%) of the AE patients with AR reported that they were currently on oral antihistamine whereas none of the non-AE group reported such usage. Both groups reported relatively higher sneezing and nasal congestion scores and low “eye watering” score. Comparing mild with moderate-to-severe AE, there was essentially no difference between the prevalence of allergic rhinitis and asthma, or severity of symptoms by ARS and ACT, but females reported more severe symptoms of sneezing and itching nose.
We conclude that allergic disorders of airway are very common among AE patients independent of the eczema severity. Most of the patients have mild-to-moderate AR and asthma. There is a lot of room for parent/patient education, and childhood eczema may prompt early awareness of these airway co-morbidities of atopy.
