Creation of a Shared Medical Decision-making Tool for Atopic Dermatitis

Atopic Dermatitis

Hypothesis/Objective : Patient-centered health care and shared decision making are key components of increasing importance which are recommended by the French Haute Autorite de Sante (HAS) and World Health Organization (WHO). In the context of dermatology and atopic dermatitis, European guidelines has promoted an active involvement from both patients and caregivers in therapeutic decisions at all stages to achieve therapeutic success and the Task Force on Atopic Dermatitis (ETFAD) has promoted the setting of treatment goals in a shared decision with the patient. The main objective of this study is to develop and cross culturally validate a tool dedicated to shared-decision in atopic dermatitis that can be used during routine dermatological consultations. The second objective is to better characterize patients seen in this context and to evaluate patients' satisfaction when empowered by shared decision. Method : We aim to develop a SDMt in AD following the recommendations of the International Patient Decision Aid Standards (IPDAS) collaboration. Development will use a multistep approach: 1) identification of priority domains for patients; 2) Selection of domains to be included in the SDMt for AD; and 3) Creation and testing of the SDMt. Participants will be consecutive adult (>18 years old) patients attending consultation for a AD in medical centres in France (Toulouse, Nantes and Créteil). All participants will provide written consent to participate. The study will be submitted for approbation to the local ethics committees of the University Hospital Centres of Paris and will be conducted according to the Declaration of Helsinki. Step 1: Identification of priority domains for patients Step 2: Selection of domains to be included in the SDMt for AD Step 3: Creation and testing of the SDMt

Vitamin D and Its Receptor Gene Polymorphisms in Lithuanian, Latvian and Taiwanese Patients With...

Atopic DermatitisAsthma

The role of vitamin D is well known in calcium and phosphate homeostasis; however, in addition to traditional functions, vitamin D has an important role in pathogenesis of different allergic diseases, such as asthma, atopic dermatitis (AD), and food allergy. There are evidences that lower cord blood vitamin D status is observed in infants with eczema. More-over, vitamin D level is decreased in subjects with asthma. One of the most important functions of vitamin D is to modulate the immune system response, both innate and adaptive, by suppressing Th2-type response and increasing natural killer cells. Vitamin D induces a higher level of IL-10, which is known as anti-inflammatory cytokine. Other studies have shown that vitamin D contributes to the conversion of CD4+ T cells to T regulatory cells. Recent studies showed that higher serum 25-hydroxyvitamin D level was associated with a reduced risk of asthma exacerbation and hospitalization. Vitamin D can enhance dexamethasone-induced MAP kinase phosphatase-1 (MKP-1) expression in peripheral blood mononuclear cells. Experimental data suggest that vitamin D can potentially increase the therapeutic response to glucocorticoid and can be used as an add-on treatment in steroid-resistant asthmatics. Vitamin D stimulates the production and regulation of skin antimicrobial peptides, such as cathelicidins, which have both direct antimicrobial activity and induced host cellular response by triggering cytokine release. Recent evidence suggests that low blood vitamin D level is a risk factor for food allergy. Vitamin D acts by binding to the vitamin D receptors (VDRs), which are located in a variety of tissues. VDRs have been identified on nearly all cells of the immune system including T cells, B cells, neutrophils, macrophages, and dendritic cells (DCs). Vitamin D deficiency predisposes to gastrointestinal infections by changing gut micro-biota, which may promote the development of food allergy. However the detail mechanism how vitamin D affects or protects the development of allergic diseases is still unknown. Vitamin D level is determined by sun exposure. Due to the fact that Lithuania, Latvia and Taiwan are located in different latitudes of north hemisphere with markedly different sun exposure, in this Joint collaboration study between Taiwan, Lithuanian and Latvia, we are going to study, (1). Serum vitamin D level in children and adults with AD and/or asthma in Lithuania, Latvia and Taiwan. (2). VDRs genetic polymorphisms of AD and/or asthma in children and adults in Lithuania, Latvia and Taiwan. (3). Finally, we would like to explore the gut microbiome of patients with AD and/or asthma in Lithuanian, Latvian and Taiwanese children and adults; and to estimate possible relationship between gut microbiome and vitamin D level and VDRs genetic polymorphisms. We believe that this study will be the first which compares the populations with different geographical and ecological factors having the same allergic diseases. We hope that these results will provide the answer about the role of vitamin D in the prevention, or in the future, in treatment of allergic diseases.

Trends in the Epidemiology and Treatment of Atopic Dermatitis in the United Kingdom (UK)

Atopic Dermatitis EczemaAtopic Dermatitis1 more

Atopic dermatitis, commonly called eczema, is one of the most frequently occurring skin conditions. It is estimated to affect around one fifth of children in developed countries and is also becoming increasingly common in less developed countries. Exact estimates of how common eczema is, vary considerably and there has not been an in-depth analysis of the number of people with eczema in the UK. It is also unclear which groups of people are most affected and which treatment options are being used. Most people with eczema are managed by their general practitioner (GP) with only a few people requiring specialist care. GP records therefore provide an excellent opportunity to explore how common eczema is and which treatments are being used currently. This study aims to provide accurate estimates of the number of people with current eczema (prevalence), number developing new onset eczema (incidence), and the pattern of common comorbidities in people with eczema. It also aims describe current treatment patterns by age groups and other factors. It also will look back over the last decade to identify how the number of people with eczema and treatments changing over time. The study will also explore patterns in the people most commonly affected and in the treatments used.

Detection of Skin Epithelial Barrier in Patients With Allergic Skin Disorders

Atopic DermatitisSkin Inflammation

The primary function of epithelial tissues is to form a barrier between the body and the external environment, in order to protect the internal tissues from environmental stresses, by minimizing water loss and preventing the entry of pathogens, pollutants and allergens. Allergic disorders, such as atopic dermatitis, have been associated to an impaired epithelial barrier function. Indeed, defects in the epithelial barriers allow tissue-damaging factors to enter the tissue and thus activate the immune response. This study aims to establish a method to assess the epithelial barrier function in vivo by electrical impedance (EI) spectroscopy, a new technique for the characterisation of epithelial tissue. By this technique, a harmless electrical signal is sent through the skin and the response of the tissue is analysed, which is influenced by several cellular properties, such as shape, orientation and size. In order to validate this technique, skin of mice was treated with some molecules able to destroy the epithelial barrier. The investigators observed that, after damaging the barrier, a decrease of the EI can be detected, consistent with the type and degree of the damage. Based on this result, the investigators believe that this technique is a good candidate as an in vivo method to determine skin barrier defects, which might be used in the future as an early diagnostic tool for the prediction of the risk to develop atopic dermatitis in young subjects, allowing the possibility to apply in time possible preventive measures. In addition, this technique might be suitable for the evaluation of a given therapy during the hospitalisation. To confirm this hypothesis, in the present study patients with atopic dermatitis will be recruited. EI measurements will be performed in both lesional and non-lesional skin and values will be compared in order to detect any difference in the electrical response due to the inflammatory state. In addition, in order to evaluate whether these patients have an appreciable defect in their skin electrical behaviour, the investigators will compare non-lesional and lesional skin of patients with skin of healthy volunteers. Peripheral venous blood and skin biopsies will be collected, in oder to characterise several immune cell populations, to detect specific skin barrier mutations and to measure serum cytokines and immunoglobulins. These and some other parameters and will be analysed in order to identify a possible correlation with the EI.
