Filter by:Prospective observational registry for an adolescent cohort with AD under the care of a dermatology provider. Approximately 1500 subjects and 75 clinical sites in North America and select European countries will be recruited to participate with no defined upper limit for either target.
This study is a multicenter, open-label, extended study to evaluate the safety, efficacy, pharmacokinetics, and immunogenicity of SHR-1819 injection in adult subjects with moderate to severe atopic dermatitis who have previously participated in the SHR-1819 injection study for atopic dermatitis (defined as the main study, referred to as the main study hereinafter).
The aim is to assess effectiveness (EASI, SCORAD, IGA, DLQI, pruritus, sleep loss) and safety (clinical and biological adverse events) of JAK inhibitors in adults with moderate-to-severe atopic dermatitis in a real-life French multicenter retrospective cohort
This prospective, non-interventional research registry is designed to study the comparative effectiveness and comparative safety of approved treatments for patients with atopic dermatitis under the care of a licensed dermatologist or qualified physician extender. Secondary objectives include analyzing the epidemiology and natural history of the disease, its comorbidities, and current treatment practices. Condition or disease : Atopic Dermatitis
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.
The objective of this study is to assess the efficacy and safety of upadacitinib combined with topical corticosteroids (TCS) for the treatment of adolescent and adult participants with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.
Although some causal factors in allergy development such as allergen exposure and environmental pollution have decreased during recent years, the incidence of the allergic diseases has increased in the Western world. Since the genetic predisposition to develop allergies cannot change in such a short time it is conceivable that, instead of the emerging of some new and unknown risk factors, some protective factors seem to have disappeared in the Western world. Allergic disease is a tendency to develop allergies to allergens in the surrounding environment. The most common symptoms are eczema and food allergy in the early life, bronchial asthma (AB) later in childhood and allergic rhino conjunctivitis (ARC) during school age and adolescence, the so-called allergic march. Some person may develop only one, but others some or all of the symptoms. Inheritance, environment and allergen exposure are important factors affecting this march but there are important factors that predict later development of diseases. Sensitization to egg (positive skin prick test or specific IgE to egg in the serum) combined with skin problems in infancy predispose strongly to the development of allergic asthma in later life. The purpose of this work is to supply children with early development of IgE associated eczema and food allergy with omega-3 LCPUFA before the age of 12 months and assess the effect of the supplementation on the future development of skin symptoms, food allergy, sensitisation against inhalant allergens and asthma in these children. We will also assess immunological markers of Th2-skewed immunity in relation to clinical effect of the supplementation. Families with children younger than 12 months referred to the paediatric department at Linköping University Hospital, Motala, Norrköping and Jönköping Hospitals in the South East of Sweden, with the diagnosis IgE associated eczema and sensitised against food allergens (egg, milk, wheat and/or soya) will be invited to participate in this study. Clinical examination by a paediatrician and assessment of disease severity with SCORAD will be performed by a research nurse at inclusion. The children will be assessed every six months by a nurse until 2.5 years of age and by a paediatrician at 3 years of age. Later clinical assessment will be performed yearly until age 7.
