The increased permeability of the skin barrier towards environmental factors such as allergens is considered a key factor in the pathogenesis of atopic dermatitis (AD). Strengthening the skin barrier through basic skin therapy represents the basis of any therapy for AD. It is well known that genetic factors as well as the skin inflammation itself contribute to the weakening of the barrier; here, recent studies have led to a deeper understanding of the complex structures of the epidermis. The possibility of counteracting the disease preventively by the use of basic skin therapy from birth on has been studied intensively in recent years. This article summarizes recent findings on the effects of basic skin therapy as a primary and secondary preventive measure.Correspondence to:

Atopic dermatitis (AD) is an inflammatory, multifactorial skin disease characterized by eczematous skin lesions, severe itching, and serious limitations in quality of life. Since 2016, TREATgermany has been a national clinical registry for patients with moderate to severe AD with around 2,550 participating patients, enabling the collection of physical, patient-reported social and psychological data as well as the collection of biosamples in routine care. TREATgermany is one of the largest academically managed AD registries in the world. This current review summarizes a selection of published analyses from registry data from TREATgermany, which retrospectively identified important correlations with regard to treatment response and safety, and investigated quality of life, performance, and mental health under everyday conditions. In addition, initial molecular signatures were identified from the blood and skin samples obtained from the patients included in the registry, which may be useful as prognostic markers.Correspondence to:

This guideline is a partial update of the S3 guideline on atopic dermatitis (AWMF register no. 013-027) published in 2023. The chapters on systemic therapy with biologics and Janus kinase inhibitors as well as the chapter on pregnancy, breastfeeding and family planning in the context of systemic therapies for atopic dermatitis have been updated. This was prompted by new approvals (lebrikizumab, nemolizumab), approval extensions (abrocitinib from 12 years of age, baricitinib from 2 years of age) and new evidence on the use of biologics before and during pregnancy. In addition, a new chapter on treatment goals, treatment expectations and criteria for treatment adjustment (“treat-to-target”) in systemic therapies has been added to the guideline. This article only presents the updated and newly added chapters. The complete guideline is available on the AWMF website.Correspondence to:
