Active clinical trials for "Dermatitis, Atopic"

Asthma is a common disease that is often diagnosed in childhood. In some teenagers, asthma symptoms disappear and treatment can be stopped; however, for some of these people, asthma symptoms return in adulthood. This study will examine data collected over the lifetime of 18-year olds to identify factors that may increase a person's chance of having recurrent asthma as an adult.

Polymorphic light eruption (PLE) is a photodermatosis with an extremely high prevalence, particularly among young women (up to 20%). The disease is characterized through itchy skin lesions on sun-exposed body sites occurring after sun exposure mostly in spring and early summer. Its etiopathogenesis is unknown but resistance to UV-induced immunosuppression with subsequent immune reactions against skin photoneoantigens has been suggested. Regulatory T cells (CD4+CD25+FoxP3+) (Tregs), a subset of T helper cells, are crucial for the induction of immunosuppression. We will test the hypothesis that PLE patients show pathogenic fluctuating Treg levels and function and related parameters over the seasons of the year, possibly being responsible for lack of immune modulation and autoimmunity in PLE. Natural or medical photohardening may normalize Treg deficiency in PLE and lead to clinical adaption in summer. Better insight into the pathogenesis of PLE may give clues to develop new therapeutic strategies.

The primary goal of the study is to investigate the impact of a common genetic polymorphism in a histamine detoxification enzyme that may well have a common role in regulating the expression of atopic dermatitis (AD) and other related atopic diseases in children.

Atopic dermatitis is a chronic skin disease with pruritus as one of its main features. Because of the symptomatic nature of their condition, pediatric patients with atopic dermatitis may preferentially seek care in the subspecialty dermatology clinic while falling behind in visits to their primary care provider. This cross-sectional study in patients attending the Dermatology Clinic at Children's Hospital of Wisconsin will screen for common conditions associated with atopic dermatitis and subsequently treat or refer patients for appropriate care. The investigators hypothesize that Milwaukee County pediatric patients with atopic dermatitis will have a high prevalence of asthma needing treatment, missed immunizations requiring catch-up, and vitamin D deficiency necessitating replacement therapy.

Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disorder associated with a decreased ability of the skin to function as an efficient immunological barrier. The disease is now two to three times more prevalent in children than it was just four decades ago. It is manifested by eczematous skin lesions associated with severe itch, leading to a significant impairment in quality of life. Of additional importance, AD oftentimes progresses to allergic rhinitis and/or asthma, a process referred to as the "atopic march." Recent reports have indicated that daily application of moisturizing creams on neonates and infants can prevent the occurrence of AD and subsequently food allergies. This is postulated to be the outcome of restoring the barrier integrity of the skin through the daily application of moisturizer.

The goal of the current investigation is to determine whether the inclusion of a parent/patient psychoeducational session in initial dermatology appointments with new pediatric atopic dermatitis patients affects (a) extent of medical follow-up, (b) patient's quality of life, and (c) parenting stress in comparison to treatment as usual for initial pediatric dermatology appointments for new pediatric patients with atopic dermatitis.

Non-atopic dermatitis (NAD) or eczema is a common inflammatory condition; potentially debilitating that can compromise quality of life. It is usually seen in childhood, but can onset within or persist into adulthood.

This study evaluates the safety and efficacy of the probiotic L. reuteri vs control product as an adjuvant for improving the skin appearance of children with mild or moderate atopic dermatitis. All children will receive the standard of care. Half of the children will receive topical L. reuteri in emollient, while the other half will receive the standard of care plus control product

Phototherapy with narrow band (nb) ultraviolet B (UVB) is a safe and effective but time consuming treatment option for patients with widespread eczema. Despite efficacy we know little about how it works, and even less why some patients fail to respond. Tintle et al showed that nb-UVB induced strong suppression of the Th2 and Th22 axes in patients with atopic dermatitis (AD), and also normalized the epidermal barrier function. We want to map the very early changes in gene expression after UVB-treatment in order to shed light on disease mechanisms, which eventually could lead to better treatment options.

This study is a randomized, double-blind, placebo-controlled bilateral study on the effect of moisturizing creams on skin barrier function. The hypothesis is that a new active emulsion has a better influence on skin barrier function comapred to its placebo.
