BACKGROUND/OBJECTIVES: Interferon gamma (IFN-γ) has been used treat severe atopic dermatitis, with equivocal results. Recurrent eczema herpeticum is an underappreciated, therapeutically challenging complication of severe atopic dermatitis. Defects in IFN-γ and other cytokine pathways have been identified in individuals with confirmed eczema herpeticum. This suggests possible benefit from IFN-γ treatment for confirmed eczema herpeticum. The objective of the current study was to evaluate immunologic and microbial parameters and response to IFN-γ treatment in children with confirmed eczema herpeticum...

BACKGROUND: Psoriasiform and eczematous eruptions are the most common dermatological adverse reaction linked to anti-TNF-α therapy. Yet, a detailed characterization of their immune phenotype is lacking. OBJECTIVES: We sought to characterize anti-TNF-α induced inflammatory skin lesions on a histopathologic, cellular and molecular level, compared to psoriasis, eczema (atopic dermatitis), and healthy control skin. METHODS: Histopathologic evaluation, gene expression (quantitative RT-PCR) and computer-assisted immunohistologic studies (TissueFAXS) were performed on 19 skin biopsies from IBD (n=17) and rheumatoid arthritis (n=2) patients with new-onset inflammatory skin lesions during anti-TNF-α-therapy...

BACKGROUND: While allergic sensitization and atopic dermatitis (AD) are known to increase the risk for allergic diseases, the impact of different temporal and clinical patterns of sensitization and AD is less well defined. OBJECTIVE: We investigated patterns of sensitization and AD from early infancy to age 3, and the differential risk for developing allergic diseases within each pattern in a general cohort. METHODS: Children (n=2629) from the Canadian Healthy Infant Longitudinal Development (CHILD) Study underwent skin prick tests and were assessed clinically for AD at ages 1 and 3 years...

Adherence to topical treatment for a variety of chronic skin conditions, such as psoriasis, acne, and atopic dermatitis, is known to be very poor. A number of factors contribute to this phenomenon, including lack of treatment efficacy and patient concerns regarding side effects, among others. At the forefront of barriers facing optimal patient adherence to topical treatment is choosing the ideal topical vehicle formulation. Medical professionals have demonstrated a lack of understanding with respect to the composition and nomenclature of the various topical formulations...

FLG mutations play a causal role in the development of ichthyosis vulgaris (IV) and are known to be a predisposing factor for atopic dermatitis (AD) in European and Asian populations. However, it remains a matter of debate how loss of function of filaggrin leads to AD. Skin barrier dysfunction due to the loss of structural proteins in the epidermis makes it easy for allergens to invade, and sensitization to the allergens, increases in serum IgE, and dermatitis follow. In addition, loss of filaggrin results in increased pH in the stratum corneum, increased serine protease activity and hyper-activation of cytokine cascades...

recent paper by Akiyama and coworkers questions one more time about role of FLG in A.D.Since first reports of heterozygous mutations of FLG in A.D. patients (1) replicated in northern European populations (2-3-4) and therefore in other populations worldwide (5), genetic studies of patient with I.V. /intrinsic A.D. of different populations of different ancestry as African American (6), and Ethiopian (7) make clear that haploinsufficiency of other structural proteins of epidermis are pathogenic for this phenotype and confirmed the Elias et al...

INTRODUCTION: Corticosteroids are the mainstay of treatment for the acute phase of atopic dermatitis (AD), whereas topical emollients are mainly used for maintenance of remission. A topical agent that combines emollient and anti-inflammatory properties would achieve control of all phases of AD, without the need for chronic corticosteroid use. AIM: To assess the efficacy of a novel topical agent containing superoxide dismutase (SOD) 100 000 IU and 4% of a combination of plant extracts (blackcurrant seed oil, sunflower oil concentrate, balloon vine extract)...

BACKGROUND: Atopic dermatitis (AD) is a prevalent disease with variable natural history. Longitudinal birth cohort studies provide an opportunity to define subgroups based on disease trajectories, which may represent different genetic and environmental pathomechanisms. OBJECTIVE: To investigate the existence of distinct longitudinal phenotypes of AD and test whether these findings are reproducible in two independent cohorts. METHODS: The presence of AD was examined in two birth cohort studies including 9,894 children from the UK (ALSPAC) and 3,652 from the Netherlands (PIAMA)...

Janus kinases (JAKs) are non-receptor protein tyrosine kinases that are expressed in many tissues. Once the JAKs are activated, a cascade of further signaling events is triggered involving phosphorylation of selected receptor chain tyrosines, binding of signal transducer and activator of transcription (STAT) proteins and phosphorylation of these STATs. Due to their ability to selectively modulate immune function, targeted JAK inhibitors are promising candidates for some skin diseases such as psoriasis and atopic dermatitis...

Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects the patients' quality of life greatly often from a very young age. Its worldwide incidence in children and adults varies, but it is usually among the first ten causes of dermatological consultation worldwide. There is a wide variety of treatment options for this condition including topical and systemic regimes. The decision to choose a treatment option in dermatological diseases is greatly influenced by the personal experience of each specialist, which increases variability in the selection of available therapies...
