About

Atopic dermatitis (AD) is a common chronic inflammatory skin disease, affecting both children (15- 20%) and adults (2-5%). The pathogenesis of AD is complex and multifactorial, including skin barrier dysfunction and immune dysregulation. AD often requires a long management and has a major impact on quality of life. For mild to moderate disease, first-line treatment involves topical therapies including corticosteroids and calcineurin inhibitors. Patients with more severe and refractory symptoms require systemic treatments as phototherapy, conventional systemic treatments (cyclosporine, methotrexate…), biologics and JAK-inhibitors.

Regardless of the severity of the disease, additional basic topical treatment with emollient is the mainstay of the management. Emollients, commonly referred to as moisturizing creams are well known for their role in moisture retention, barrier repair and symptom control in AD.

Publications on emollient in atopic dermatitis are numerous but there are limited data on how patients with AD treated by systemic treatment use and evaluate emollients.

The aim of this study is to characterize and describe the population of subjects suffering from moderate to severe AD, treated and controlled by systemic treatments in terms of pathology, the state of their skin at this stage of their systemic treatment (controlled period), their habits, needs and expectations regarding the use of emollient.

This study will be conducted as an exploratory, proof of concept, international, multicentric study in adult subjects suffering from moderate to severe AD, treated and controlled by systemic treatments.

2 visits are planned: Visit 1 (Day 1): Inclusion Visit 2 (from Day 2 to Day 8): End-of-study visit - remote visit for subject's questionnaire filling The maximal duration of participation for a subject is 8 days.

Enrollment: 100 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
