Active clinical trials for "Dermatitis, Atopic"

The purpose of this study is to characterize the bacterial strains that colonize children with atopic dermatitis. The investigators hypothesize that rectal cultures will be more sensitive than anterior nares cultures for detecting S. aureus colonization, and that strains of S. aureus colonizing patients with atopic dermatitis will be resistant to commonly used topical antibiotic ointments.

The purpose of this study is to look at how defects in the skin barrier and immune response affect risk for skin infections. Participants will be classified into 4 groups based on Atopic Dermatitis (AD)/Non-Atopic (NA) status and Staphylococcus aureus (S. aureus) colonization (negative or positive): AD S. aureus negative AD S. aureus positive NA S. aureus negative and NA S. aureus positive.

The purpose of this multi-center, clinical registry study is to determine genetic markers associated with susceptibility of AD patients to infections and to also serve as a potential participant database for future studies.

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

Hand washing and the use of hand sanitizers are important interventions in disease prevention. Engaging in frequent hand washing is especially effective in preventing the spread of viruses, as this removes microbes and prevents the spread to others. Hand dermatitis, however, is a common occurrence in certain occupations, such as healthcare workers. With the onset of the SARS-CoV2 (COVID-19) pandemic, hand hygiene measures are further enforced as there is no cure or vaccine for this virus. In the study, the effects of hand washing and the use of hand sanitizer on skin proteins and lipids will be assessed.

Atopic dermatitis is a skin disorder with an itchy, red skin rash. This may be because certain proteins are increased in the skin of AD patients. The increased expression of these proteins play an important role in the development of AD and may increase the risk for persons with AD to get skin infections and allergies. There are very few non-invasive ways to diagnose and monitor the development and progression of atopic dermatitis. The goal of this study is to develop laboratory tests, done on skin samples collected by tapy stripping, that can be used for early detection and monitoring the response to treatment for a variety of skin diseases, including atopic dermatitis.

While many patients with atopic dermatitis (eczema) can be managed with topical creams and treatments for itch, some children have such severe, long-standing disease that they need treatment with oral medications that decrease the ability of the immune system to react. However, there is not enough information on the proper use of these medications or how well they work compared with each other. The current study looks at the response of children treated with these medications to provide this information and improve their use.

Prurigo nodularis (PN) is a skin condition characterized by symmetrically distributed widespread, pruritic nodules that occurs in patients with chronic pruritus. There are 2 subtypes of PN depending on the association with an atopic dermatitis (AD) : atopic PN (Besnier) and non-atopic PN (Hyde). There are no approved therapies, and treatment options currently used have limited efficacy and their long-term use carries the risk of potential severe toxic effects. The mechanisms triggering PN are still unknown. However, recent findings suggest a major role for the Th2 inflammatory pathway. Beyond advancing the basic understanding of PN pathophysiology, our study might also pave the way for developing novel Th2-targeted therapeutic strategies for PN and AD. The primary objective of this study is to characterize the transcriptional profile of the T lymphocytes isolated from skin samples from patients with PN. This study will allow a gain a deeper understanding of the pathophysiologic mechanism of PN, a better classification of its subtypes, as well as their physiopathologic link with AD. Moreover, it will help shape new effective and safe therapeutic approaches in these diseases which are important for optimal therapeutic management.

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease. Clinical studies have demonstrated a link between staphylococcal skin colonization and the pathogenesis of AD, but the implication of bacterial virulence factors remains largely uncharacterized. Finally, AD is often associated with herpes simplex skin infections. The aim of this project is to investigate the role of staphylococcal toxins in the exacerbation and maintenance of atopic skin inflammation and in the occurrence of infectious complications such as eczema herpeticum.
