Filter by:The purpose of this study is to investigate the differences in the quality of life of patients and caregivers who are treated by general pediatricians versus pediatric dermatologists for eczema (atopic dermatitis or AD).
Narrowband ultraviolet B phototherapy is the "standard" phototherapy for atopic eczema; ultraviolet A1 is sometimes used but is not a widely available treatment. We do not know the most important chromophores in treating atopic eczema; in which phototherapy is thought to work by improving epidermal barrier function, having beneficial effects on skin microbiome and local immunosuppression. It seems plausible that there are several chromophores and that 'targetting' several at once with different wavebands should help and for severe eczema that has not responded adequately to narrowband UVB or ultraviolet A1 alone the combination is sometimes used. This study is to test if the combination is moderately to greatly more effective than narrowband ultraviolet B monotherapy amongst patients referred for any form of first-line phototherapy for atopic eczema.
The purpose of this study is to assess the efficacy and safety of OPA-15406 ointment in patients with atopic dermatitis.
Atopic dermatitis and psoriasis are two skin diseases often associated with bacterial infections and inflammation. Studies indicate that skin cells from these patients may have some changes that make these patients more susceptible to bacterial infections. Inflammatory environment may have an effect on the function of skin cells. The purpose of this study is to learn more about skin cells (keratinocytes and fibroblasts) and how they regulate skin barrier function. To study this we need to establish skin cells that can be grown in the laboratory. We will use small skin biopsies from patients with atopic dermatitis, psoriasis and healthy people as a source of these cells. Since these skin cells have a limited lifetime when grown in laboratory as part of the project we would like to modify them, which allows them to grow for long time in the research laboratory. Some of the collected skin biopsies and isolated skin cells will be used to examine what gene products they make.
This study will investigate the safety and clinical efficacy of a novel doxycycline topical formulation in subjects with Atopic Dermatitis (AD). The investigators hypothesize that daily application of the study drug in AD subjects will reduce severity of the disease, by reducing skin driven inflammation and restoring skin barrier function. The investigators will also monitor the anti-microbial activity of this product on AD skin, as colonization with Staph aureus is typically associated with disease severity.
Atopic Dermatitis (AD), also known as eczema, is a common skin disease characterized by itchy lesions. The prevalence of AD has increased over the past few decades, with 15-30% of children and 2-10% of adults being affected. The lesions of atopic dermatitis patients are very inflamed, with an increased number of inflammatory cells in the skin. The first line treatment for AD is steroids, which reduce inflammation in the skin. There are several ways to measure if the treatment is effective, including clinical and cellular. We are proposing that a controlled skin allergen challenge will be an effective way to measure the effect of steroid at a cellular level through the measurement of inflammatory cells in the late cutaneous response. This will be examined using a placebo-controlled trial.
The prevalence of allergic diseases (atopic dermatitis, asthma, rhinitis, conjunctivitis and food allergy) has increased dramatically in industrialized countries over the last 20-30 years. Allergic diseases are present especially in children and young adults, but all age groups are affected, with variations across countries and age. To propose new therapies, the investigators must first understand the physiopathology. Since their discovery the regulatory T cells have continued to be the subject of work to understand their role in maintaining immune homeostasis in the human body but also their involvement in autoimmune diseases, inflammatory diseases, transplants of solid organs or fluids and allergic diseases. It was identified two broad classes of regulatory T cells: - T cells = natural regulators acquisition of a phenotype and a regulatory function right out of the thymus ( CD25 + / CD127 + low / FoxP3 +). - T cells induced regulators = acquisition of a phenotype and a regulatory function on the periphery depending on the cytokine micro-environment. Phenotypic characterization of these is less obvious and even more so than during the last ten years several induced regulatory T cell populations have been described ( eg, Tr1 ). A new subpopulation of T cells induced in patients with inflammatory bowel disease recently identified have a particular phenotype as bearing the CD4 and CD8 double marking with a regulatory phenotype. These regulatory T cells are also induced a specific of a commensal intestinal bacterium (Faecalibacterium prausnitzii). Regarding allergies, it has been widely demonstrated a relationship between changes of the intestinal microbiota and the occurrence of allergic diseases. The investigators would therefore propose a cross-sectional study, single-center, controlled, single blinded to study the role of T cells called double positive induced regulators DP8 to compare the frequency and the regulatory function of specific DP8 of Faecalibacterium prausnitzii in atopic dermatitis, asthma and allergic rhinitis compared to control samples.
The primary objective of this study is to investigate the effectiveness of a standardized skin care regimen using a milk lotion once daily and a bathing addendum as needed during the first 52 weeks of life on the development of atopic Dermatitis (AD) compared to no structured skin care regimen in infants with atopic predisposition. Secondary objectives are to investigate the influence of a structured skin care regimen on the development of AD in the second year of life and the skin barrier function up to the infants' age of 2 years.
Atopic Dermatitis is a chronic relapsing eczematous skin disease with increasing prevalence. Complementary and alternative medical approaches have been employed to relieve symptoms of Atopic Dermatitis. We aim to establish basic clinical efficacy and safety data for Jaungo in patients with Atopic Dermatitis.
