Atopic dermatitis (AD) in childhood is a common disease with prevalence rates as high as 20%. Its early onset in infancy and its chronic relapsing course puts a special burden on families. Supporting parents in dealing with the management of AD presents a challenge for physicians. The objective of this study was to determine the effect of a structured parental training program on managing AD in children. Two-hundred and four families participated in a prospective, randomized controlled trial. Children (5 months to 12 years in age) had suffered from moderate-to-severe AD for at least 4 months. They were randomly assigned to either the intervention group or a waiting, control group who could participate in the training program 1 year later. The intervention was an inter-disciplinary, structured educational program which covered medical, nutritional, and psychological issues in six group sessions of 2 h each. The families were assessed at the beginning of the study and 1 year later. Main outcome measures were: severity of eczema (SCORAD); treatment habits; treatment costs; quality of life; and coping strategies. Significant effects were shown regarding treatment behavior, such as regular use of emollients, use of antiseptics and topical steroids in the event of exacerbation, and a reduction in the use of unconventional therapies. Satisfaction with medical treatment was improved, and rumination as an ineffective coping strategy was reduced. Finally, significant reduction of treatment costs was achieved. We conclude that structured training programs for parents of children with AD is a helpful adjunct to dermatological treatment.

Atopic dermatitis (eczema) is a chronic inflammatory skin disease with onset mainly in early childhood It is commonly the initial clinical manifestation of allergic disease, often preceding the onset of respiratory allergies. Along with asthma and allergic rhinitis, atopic dermatitis is an important manifestation of atopy that is characterized by the formation of allergy antibodies (IgE) to environmental allergens. In the developed countries, the prevalence of atopic dermatitis is approximately 15%, with a steady increase over the past decades. Genetic and environmental factors interact to determine disease susceptibility and expression, and twin studies indicate that the genetic contribution is substantial. To identify susceptibility loci for atopic dermatitis, we ascertained 199 families with at least two affected siblings based on established diagnostic criteria. A genome-wide linkage study revealed highly significant evidence for linkage on chromosome 3q21 (Zall=4.31, P= 8.42 10(-6)). Moreover, this locus provided significant evidence for linkage of allergic sensitization under the assumption of paternal imprinting (hlod=3.71,alpha=44%), further supporting the presence of an atopy gene in this region. Our findings indicate that distinct genetic factors contribute to susceptibility to atopic dermatitis and that the study of this disease opens new avenues to dissect the genetics of atopy.
