IN ATOPIC DERMATITIS,
CORE OF THE DISEASE
Atopic dermatitis is a common, chronic skin disorder that has been shown to be associated with a multitude of comorbid allergic diseases.2 Patients’ skin, including nonlesional skin, suffers from hidden signs of persistent inflammation, even after the itch has subsided.3-5 This underlying, chronic inflammation is a significant source of lesions and itch, the primary signs and symptoms of the disease.3-5 The Th2 inflammatory response that manifests as disease activity overtly during exacerbations persists subclinically even after the flare has subsided.3,4 Addressing the source of underlying, persistent inflammation may be key to keeping current and future disease signs and symptoms, including itch, at bay.4,5
In general, there is a reactive and episodic approach to the management of atopic dermatitis in which physicians often rely on superficial measures of symptoms and control.1 These therapeutic approaches for treating atopic dermatitis can be effective in some patients; however, these options may not be adequate in all patients.1
Unfortunately, patients with atopic dermatitis feel trapped in a cycle of frequent, unpredictable flares that last days, weeks or even longer, along with persistent itching and lesions.7 Disease management should consider a proactive approach to control, including a reduction in the number and severity of exacerbations and an increase in duration between exacerbations.6,7
A proactive approach is warranted for management of the persistent inflammatory process, which, even if subclinical, is always present.8
