This document discusses the management of atopic dermatitis (AD). It covers the epidemiology, risk factors, clinical presentation, conventional therapies, and role of topical corticosteroids in treating AD. Specifically, it notes that AD is a chronic inflammatory skin disease affecting 15-30% of children and 2-10% of adults. Genetic and environmental factors like allergens and irritants play a role. Treatment focuses on eliminating triggers, moisturizing, and using topical corticosteroids in a stepwise approach depending on severity.

As a result of genetically determined epidermal-barrier dysfunction and the effect of environmental factors, nonatopic dermatitis is the first manifestation of atopic dermatitis. Subsequently, because of their genetic predisposition for IgE-mediated sensitization, patients become sensitized. This phenomenon is favored by Staphylococcus aureus enterotoxin products. Finally, scratching leads to tissue damage and the release of structural proteins, triggering an IgE response in patients with atopic dermatitis. This sensitization to self-proteins can be due to the homology of allergen-derived epitopes and human proteins in the context of molecular mimicry.

difference between active and placebo covers at 6 months was highly significant (p=002). severity of eczema decreased in both groups, but active group showed significantly greater improvements in severity score (difference between mean final scores 4.3 units, p=0.006)

consumption of high-potency corticosteroids ( fig. 2 a) was significantly lower in the emollient group compared to the control group from D0 to D21 [8.87 8 1.37 g vs. 4.86 8 0.97 g (–45.2%), p = 0.019] and from D0 to D42 [14.7 8 2.08 g vs. 8.56 8 1.74 g (–41.8%), p = 0.025]. consumption of moderate-potency topical corticosteroids from D0 to D21 and D42 in the 2 study groups is shown in figure 2 b. From D0 to D21 and from D0 to D42, the emollient group consumed slightly less moderate- potency topical corticosteroid than the control group (4.66 8 0.65 g vs. 4.91 8 0.75 g and 7.43 8 1.13 g vs. 8.03 8 1.23 g, respectively), but this difference of consumption was not significant either at D21 (–5.1%, p = 0.8043) or D42 (–7.5%, p = 0.722).
