BACKGROUND: Phenotypes of childhood-onset asthma are characterized by distinct trajectories and functional features. For atopy, definition of phenotypes during childhood is less clear. OBJECTIVE: To define phenotypes of atopic sensitization over the first 6 years of life by a latent class analysis (LCA) integrating three dimensions of atopy: allergen specificity, time course, and levels of specific IgE. METHODS: Phenotypes were defined by LCA in 680 children of the MAS and 766 of the PASTURE birth cohorts and compared to classical non-disjunctive definitions of seasonal, perennial, and food sensitization with respect to atopic diseases and lung function...

Atopic dermatitis comorbidities extend well beyond the march to allergic conditions (food allergy, asthma, allergic rhinitis, allergic conjunctivitis, and eosinophilic esophagitis), suggesting both cutaneous and systemic immune activation. In reviewing atopic dermatitis comorbidities, Councilors of the International Eczema Council found a strong pattern of immune activation in peripheral blood and the propensity to both skin and systemic infections. Associations with cardiovascular, neuropsychiatric, and malignant diseases were increasingly reported, but confirmation of their link with atopic dermatitis requires longitudinal studies...

The permeability barrier plays an important role in numerous skin diseases. Particularly well known is the importance of this barrier in eczema. In irritative-toxic contact dermatitis, the first step in the pathogenesis is the disturbance of the permeability barrier by irritative-toxic noxious substances. Only after damage to the barrier is achieved can irritants and allergens penetrate into the living epidermis. In atopic eczema due to an impaired barrier, allergens penetrate from the environment into the skin and cause or worsen the eczema...

According to the hygiene hypothesis, insufficient immune activation by microbes increases the risk of allergy development. Staphylococcus aureus, which is part of the skin and gut microbiota of infants in Western countries, produces a variety of T-cell-activating enterotoxins, called superantigens. We investigated whether early (0-2 months of age) gut colonisation by S. aureus strains that carry specific superantigens and adhesins was related to subsequent development of atopic eczema in a Swedish birth-cohort...

BACKGROUND: Atopic dermatitis (AD) is a common, complex disease that follows a chronic relapsing course and significantly affects the quality of life of patients. Skin barrier dysfunction and inflammatory processes induce and aggravate this skin condition. Proper use of an emollient for hydration is a keystone of AD treatment. Bee venom is known to have anti-inflammatory effects and has been widely used in traditional medicine to treat various inflammatory disorders. OBJECTIVE: To find out the beneficial effect of an emollient containing bee venom in the treatment of patients with AD...

BACKGROUND: It has recently been suggested that patients with moderate to severe atopic dermatitis (AD) may profit from anti-interleukin (IL)-12/-23 p40 therapy. OBJECTIVE: We sought to assess the immunologic effects of ustekinumab treatment on AD skin and to correlate them with the clinical efficacy of this drug. METHODS: We investigated the course of 3 patients with severe AD who were administered 45 mg of subcutaneous ustekinumab over a period of 16 weeks...

BACKGROUND/OBJECTIVES: Children with atopic dermatitis are at increased risk of both general behaviour problems, and those specific to the condition and its treatment. This can hamper the ability of parents to carry out treatment and manage the condition effectively. To date, there is no published instrument available to assess child behaviour difficulties in the context of atopic dermatitis management. Our aim was to develop a reliable and valid instrument to assess atopic dermatitis-specific child behaviour problems, and parents' self-efficacy (confidence) for managing these behaviours...

Background Dupilumab, a human monoclonal antibody against interleukin-4 receptor alpha, inhibits signaling of interleukin-4 and interleukin-13, type 2 cytokines that may be important drivers of atopic or allergic diseases such as atopic dermatitis. Methods In two randomized, placebo-controlled, phase 3 trials of identical design (SOLO 1 and SOLO 2), we enrolled adults with moderate-to-severe atopic dermatitis whose disease was inadequately controlled by topical treatment. Patients were randomly assigned in a 1:1:1 ratio to receive, for 16 weeks, subcutaneous dupilumab (300 mg) or placebo weekly or the same dose of dupilumab every other week alternating with placebo...

Conventional culture-based studies have suggested that a reduction in microbial exposure in early life predisposes to atopic eczema and allergies. However, molecular microbiological methods have shown that conventional culture fails to grow around 80% of the bacterial flora. More recent work reviewed in this paper has employed next generation sequencing to study the influence of the gut and skin microbiota, both with regard to the risk of developing atopic eczema but also the role of pathogenic and commensal bacteria in established disease...

This review considers, in the context of British Skin Foundation (BSF)-funded translational research into atopic eczema conducted in Newcastle, the complex interactions between clinical and non-clinical scientists in both academia and industry and how this may have impacted on clinical care. However, research in individual centres does not occur in isolation and clinically relevant outcomes from collaborative research are increasingly supported through regional and national networks. This is illustrated by our trial of azathioprine in adults with atopic eczema conducted across centres in the North East of England that employed pharmacogenetic dosimetry...

The main proteinaceous component of the keratohyalin granules within the granular layer keratinocytes of the epidermis is the giant, repetitive polyprotein profilaggrin. When granular layer cells commit to terminal differentiation to form the flattened squames of the stratum corneum, profilaggrin is rapidly cleaved into multiple copies of the 37 kDa filaggrin monomer, which binds to and condenses the keratin cytoskeleton, thereby facilitating cellular compression. Within the stratum corneum, filaggrin is broken down to form natural moisturising factor, a pool of amino acids and derivatives thereof that exerts multiple effects...

Clinical trials often continue to be undertaken even though the effectiveness of the intervention under consideration has already been demonstrated. In addition, vehicle- or placebo-controlled studies predominate over head-to-head comparisons, although the latter would be more informative for clinicians in guiding patient management. This creates research waste, and both investigators and funders are to blame. Wilkes et al. used a network analysis approach to show duplication of effort in trials assessing topical calcineurin inhibitors and corticosteroids as treatment options for atopic eczema...
