INTRODUCTION: Dupilumab significantly improves signs and symptoms of atopic dermatitis (AD), including pruritus, symptoms of anxiety and depression, and health-related quality of life versus placebo in adults with moderate-to-severe AD. Since the cost-effectiveness of dupilumab has not been evaluated, the objective of this analysis was to estimate a value-based price range in which dupilumab would be considered cost-effective compared with supportive care (SC) for treatment of moderate-to-severe AD in an adult population...

Objective: Atopic dermatitis (AD) is a prevalent, burdensome, and psychologically important pediatric concern. Probiotics have been suggested as a treatment for AD. Some reports have explored this topic; however, the utility of probiotics for AD remains to be firmly established. Methods: To assess the effects of probiotics on AD in children, the PubMed/Medline, Cochrane Library Scopus, and OVID databases were searched for reports published in the English language. Results: Thirteen studies were identified. Significantly higher SCORAD values favoring probiotics over controls were observed (mean difference [MD], -3...

Studies have suggested that Bacillus Calmette-Guérin (BCG) vaccination may reduce the risk of allergic diseases, including atopic dermatitis. The Danish Calmette Study was conducted 2012-2015. Within 7 days of birth new-borns were randomised 1:1 to BCG or no BCG. Exclusion criteria were gestational age <32 weeks, birth weight <1000 g, known immunodeficiency or no Danish-speaking parent. Data were collected through telephone interviews and clinical examinations until 13 months. Clinical atopic dermatitis was diagnosed in 466/2,052 (22...

GATA3 is a transcription factor with an important role in atopic diseases because of its role in the differentiation of Th2 lymphocytes. Moreover, GATA3 is expressed in keratinocytes and has a role in keratinocyte differentiation and the establishment of the epidermal barrier. In this study, we investigated the role of GATA3 in keratinocytes in the context of epidermal barrier integrity under inflammatory skin conditions. When analysing skin samples from atopic dermatitis and psoriasis patients or healthy controls, we detected decreased expression of GATA3 in the stratum spinosum and stratum granulosum of atopic dermatitis and psoriasis patients when compared to healthy controls...

Group 2 innate lymphoid cells (ILC2s) are involved in human diseases, such as allergy, atopic dermatitis and nasal polyposis, but their function in human cancer remains unclear. Here we show that, in acute promyelocytic leukaemia (APL), ILC2s are increased and hyper-activated through the interaction of CRTH2 and NKp30 with elevated tumour-derived PGD2 and B7H6, respectively. ILC2s, in turn, activate monocytic myeloid-derived suppressor cells (M-MDSCs) via IL-13 secretion. Upon treating APL with all-trans retinoic acid and achieving complete remission, the levels of PGD2, NKp30, ILC2s, IL-13 and M-MDSCs are restored...

The strong societal urge to reduce the use of experimental animals, and the biological differences between rodent and human skin, have led to the development of alternative models for healthy and diseased human skin. However, the limited availability of primary keratinocytes to generate such models hampers large-scale implementation of skin models in biomedical, toxicological, and pharmaceutical research. Immortalized cell lines may overcome these issues, however, few immortalized human keratinocyte cell lines are available and most do not form a fully stratified epithelium...

Plexin-B2 (PlxnB2) and its ligand, CD100 (Semaphorin 4D), are originally identified as axon-guidance molecules that function during neuronal development; however, studies also showed that CD100-Plexins participate in various immune responses. In the present study, we found that the expression of PlxnB2 on keratinocytes was specifically increased in lesional skin of psoriasis patients, but not atopic dermatitis. Levels of soluble CD100 (sCD100) and membrane CD100 (mCD100) were elevated in sera of psoriasis patients and on keratinocytes of psoriatic skin, respectively...

Eczema herpeticum (EH) is characterized by viral infection of a preexisting inflammatory dermatosis and is associated with considerable morbidity. In this cross-sectional study, we sought to determine the incidence, risk factors, comorbidities, costs of care, length of stay, and mortality in hospitalized US children with EH. The Nationwide Inpatient Sample 2002-2012, containing a 20% sample of all US hospitalizations, was analyzed. We used a validated approach involving ICD-9-CM codes to identify patients primarily admitted for EH (n=4655 weighted)...

Living in a hard water area is associated with an increased risk of atopic dermatitis (AD). Greater skin barrier impairment following exposure to surfactants in wash products combined with high calcium, and/or chlorine, levels in hard water is a compelling mechanism for this increase. The purpose of this study was to investigate this mechanism in individuals with and without a predisposition to skin barrier impairment. We recruited 80 subjects; healthy controls and AD patients with and without FLG mutations...

The skin is in daily contact with environmental pollutants, but the long-term effects of such exposure remain under-investigated. Many of these toxins bind and activate the pregnane x receptor (PXR), a ligand-activated transcription factor that regulates genes central to xenobiotic metabolism. The objective of this work was to investigate the effect of constitutive activation of PXR in the basal layer of the skin to mimic repeated skin exposure to noxious molecules. We designed a transgenic mouse model which overexpresses the human PXR gene linked to the herpes simplex VP16 domain under the control of the keratin 14 promoter...

BACKGROUND: Oral immunosuppressive drugs are frequently prescribed in young women with atopic dermatitis (AD). Immunocompromised patients may have a higher risk of developing high risk HPV infections, CIN and cervical carcinoma. Most literature on patients using oral immunosuppressive drugs is available in organ transplant patients. Literature on the risk of developing cervical carcinoma in AD patients treated with oral immunosuppressive drugs is lacking. At this moment there is no clear guideline/consensus on this topic, but in daily practice, questions arise concerning whether this risk is increased and whether more intensive screening in women using immunosuppressive drugs should take place...

Evidence has emerged about the relationship between atopic dermatitis (AD) and autoimmune diseases, but the underlying mechanism of this association is complex and still unclear. Recent epidemiological data from the published work suggest a positive correlation. The aim of this review is to analyze the frequency of co-occurrence of AD and autoimmune diseases. Our systematic review included 22 articles from PubMed describing the reciprocal association between AD and autoimmune diseases. Although not all the studies achieved statistically significant results, patients suffering from autoimmune diseases involving skin and intestinal mucosa, such as vitiligo, alopecia areata, celiac disease and inflammatory bowel diseases, showed a higher risk to have AD as comorbidity...

BACKGROUND: Pathophysiology of type 1 autoimmune pancreatitis (AIP) is still unclear. We previously reported that M2 macrophages might play an important role in type 1 AIP. Recently, it has been reported that basophils regulate differentiation to M2 macrophages. In this study, we investigated basophils from the pancreatic tissue and peripheral blood of individuals with type 1 AIP. METHODS: By using immunohistochemistry, we investigated basophils in pancreatic tissue from 13 patients with type 1 AIP and examined expression of toll-like receptors (TLRs) by these cells...

Skin is an organ that is susceptible to damage by external injury, chronic inflammation, and autoimmunity. Tissue damage causes alterations in both the configuration and type of cells in lesional skin. This phenomenon, called tissue remodeling, is a universal biological response elicited by programmed cell death, inflammation, immune disorders, and tumorigenic, tumor proliferative, and cytoreductive activity. In this process, changes in the components of the extracellular matrix are required to provide an environment that facilitates tissue remodeling...

Atopic dermatitis (AD) and psoriasis are one of the common skin diseases. Animal models are a powerful tool to analyze these diseases, which are complicated by multiple cytokine pathways. However, many discrepancies between the human diseases and murine models have been noticed. Therefore, investigators should be aware of the differences between the murine AD models and human AD when translating murine data to human skin diseases. This review highlights the differences between the inflammatory profiles between murine models and human diseases focusing on AD and psoriasis...

BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing, inflammatory skin disorder. One of the most disturbing symptoms of AD is pruritus. The first line treatment for AD is topical corticosteroids, topical immunomodulators, topical barrier creams, oral antihistamines, and systemic treatments. Desoximetasone 0.25% spray is a superpotent topical corticosteroid delivered in a novel way and it may be a suitable option for the treatment of pruritus in adult atopic dermatitis patients...
