Atopic Dermatitis Eczema

The Global Healthcare Study on Atopic Dermatitis (GHSAD) is an international, multicenter observational study hosted by the University of Zurich (UZH) investigating healthcare access, treatment patterns, disease severity, and quality of life in patients with atopic dermatitis. The study collects standardized clinical data from routine medical records to identify disparities in healthcare delivery and outcomes across different healthcare systems.

Study Overview Atopic dermatitis (AD), commonly known as eczema, is a chronic inflammatory skin condition characterized by intense itching and skin barrier damage. While researchers know that the immune system is overactive in AD, it is difficult to measure the exact level of "damage" or "inflammation" happening deep within the skin using only a physical exam. The Purpose of This Study This study investigates a specific "danger signal" called circulating cell-free DNA (cfDNA). When skin cells are damaged or die due to inflammation, they release tiny fragments of DNA into the bloodstream. The investigators believe these fragments might act as a trigger for the immune system, worsening the disease. What the Study Involves Researchers will collect blood samples and small skin biopsies from patients with AD and healthy volunteers. The study aims to: Compare the levels of cfDNA in the blood of AD patients versus healthy individuals. Determine if higher levels of cfDNA correlate with more severe skin symptoms (measured by scores like SCORAD and EASI). Examine how immune cells in the skin (macrophages) respond to these DNA fragments through a specific biological switch called the STING pathway. Potential Impact By understanding this "damage-signal" loop, this research may lead to new ways for doctors to monitor AD severity through simple blood tests and could identify new targets for future anti-inflammatory treatments.

The goal of this clinical trial is to demonstrate the feasibility of a trial that examines the impact of changes in dietary sodium intake on skin sodium levels, atopic dermatitis, and psoriasis. In addition, it aims to generate preliminary data to begin to answer the following questions: 1. Is there an association between skin sodium concentration and atopic dermatitis and psoriasis severity? 2. Are changes in dietary sodium are associated with changes in skin sodium concentration and atopic dermatitis and psoriasis severity? Researchers will compare sodium tablets to a placebo (a look-alike substance that contains no drug) to specifically examine the impact of altering sodium intake. Participants will: * Follow a low-salt diet for the duration of the 13-week study * Take sodium chloride tablets every day for 5 weeks followed by a placebo every day for 5 weeks after a 2-week washout period, or vice versa * Visit the clinic up to 4 times to answer questionnaires, provide bio samples, complete dietary recalls, and undergo non-contrast sodium MRI

The purpose of this study is to evaluate the efficacy and safety of different dose regimens of IMG-007, compared to placebo.

Atopic dermatitis (AD) is a chronic inflammatory skin disease with pruritus and recurrence of eczematous eruptions. Evaluation of response to treatment are only clinical using Eczema Area Severity Index (EASI), SCOring of Atopic Dermatitis Index (SCORAD) scores, with a risk of intra-observer variations. Tralokinumab is a fully human anti-IL-13 monoclonal antibody that has proven to be effective and well-tolerated for the treatment of patients with moderate-to-severe AD. Reflectance confocal microscopy (RCM) is a noninvasive procedure that allows to evaluate epidermis and papillary dermis at a cellular level. RCM allows skin structural and inflammatory parameters evaluation. The aim of this study is to evaluate by RCM skin modifications of AD patients treated with tralokinumab.

The goal of this observational registry is to characterize the clinical features, severity, treatments, and outcomes of patients with atopic dermatitis in Costa Rica receiving systemic and advanced therapies in routine clinical practice. The main questions it aims to answer are: What are the demographic and clinical characteristics of patients with moderate-to-severe atopic dermatitis treated in specialized dermatology centers in Costa Rica? What treatments are used in real-world practice and how do they impact disease severity and patient-reported outcomes over time? Participants with atopic dermatitis receiving systemic or advanced therapies as part of their usual medical care will be followed longitudinally, with collection of clinical severity scores, treatment patterns, and outcomes during routine visits.

The main purpose of this study is to see how well different doses of soquelitinib work in participants with atopic dermatitis (AD) as compared to a placebo (pill with no medicine in it). To check this, the study doctors will examine participants' skin regularly to track how their AD changes during the study. The study doctors will see how safe soquelitinib is by tracking side effects among participants. They will also check "tolerability," which means how well the participants can handle soquelitinib and whether any potential side effects are manageable for them. To understand how well soquelitinib works, it will be compared with a placebo. Placebo is a substance that looks like soquelitinib but contains no active medicine in it. Participants will: * Take study treatment (soquelitinib or placebo) every day for 12 weeks * Visit the clinic for check-ups and tests every week for the first 2 weeks then every 2 weeks during the treatment period, and then return for follow-up visits 30, 60, and 90 days after the last dose of study treatment

Skin moisturization is important for patients with atopic dermatitis, commonly known as eczema. Moisturizing right after bathing is widely accepted as the best method to keep skin hydrated. However, there is conflicting research on the timing of moisturizing. The goal of this clinical study is to evaluate the preference of moisturizing while showering/bathing compared to after towel drying in adolescents aged 12-18 with eczema. The main question it aims to answer are: * Which moisturization technique is preferred: while showering/bathing or after towel drying? * How do these techniques affect investigator-assessed eczema severity, patient-reported itch scores, and objective skin hydration measurements? Researchers will compare applying moisturizer while in the shower/bath to after towel drying and to which technique is preferred among participants and if there are different effects on eczema and skin hydration. Participants will: * Apply moisturizer while showering/bathing for one month and after towel drying for one month. * Complete questionnaires on moisturization technique, skin feel, and itchiness. * Undergo skin hydration measurements using a Corneometer® CM825 device.

The goal of this randomized controlled trial is to study the (cost)effectiveness of extending the intervals between dupilumab doses in patients with well-controlled atopic eczema, while considering physician- and patient-reported disease severity, quality of life, and dupilumab serum trough levels. Patients will be divided randomly into three groups, receiving dupilumab 300 mg every 2 weeks, every 3 weeks, or every 4 weeks. Researchers will then compare the outcomes among these three groups.

It's common for infants to be unsettled, especially in the first few months of life. While this is often normal, persistent symptoms can be stressful for families. Parents naturally seek explanations, and common suspected causes include colic, reflux, eczema, and cow's milk allergy (CMA). However, CMA is frequently over diagnosed, which can lead to unnecessary changes such as stopping breastfeeding or switching to expensive specialist formulas. To address this, we've developed an online questionnaire to help track and understand symptoms in unsettled infants. Our long-term goal is to use this tool to support more accurate diagnosis of CMA. Before that, we need to test and validate the questionnaire in a general population of infants, including those who are healthy and those with other temporary conditions like a recent immunisation or teething. This study involves an anonymous online survey for parents of babies under 12 months old. We aim to collect data from approximately 350 participants. The study will help us assess how well the questionnaire reflects the severity of symptoms and whether it can distinguish between healthy infants and those with underlying issues. Parents will be invited to take part using flyers with a QR code distributed in various healthcare settings, including GP clinics and children's clinics in hospital. The survey is anonymous and hosted on a secure platform. While we don't anticipate the questions to be distressing, we recognise some may touch on sensitive topics. Support resources and study team contact details will be provided. By validating this tool, we hope to improve how unsettled behaviour in infants is assessed-reducing unnecessary interventions and better supporting families and healthcare professionals.

This project proposes a randomized controlled human study to explore the prebiotic effects of consuming mulberry juice on atopic dermatitis in children and adolescents. The study aims to investigate the potential of mulberry fruit as a human prebiotic. This human study will recruit up to 120 participants from the Taipei Medical University Hospital (commissioned by the Ministry of Health and Welfare). Participants will be divided into experimental groups and a control group, with a 3-month intervention involving five clinical assessments and three stool collections. The goal is to compare the severity of atopic dermatitis, gut microbiota, and metabolite changes during the 6 days of mulberry juice consumption between the experimental and control groups. This project will help establish mulberry fruit as a potential human prebiotic and adjunctive treatment for alleviating atopic dermatitis in children.

Atopic dermatitis (AD), also known as atopic eczema, is a chronic inflammatory skin disorder. The current first-line recommended treatment for AD is the use of emollients, topical corticosteroids (TCS), and oral antihistamines if necessary. However, patients often have side effects like skin atrophy and telangiectasia. And there were plenty of herbal medicine which are beneficial to atopic dermatitis in ancient Chinese medicine books and records. Therefore, the purpose of this study is to develop a new topical application of traditional Chinese medicine and evaluate its clinical efficacy in AD patients. In human trial, 66 Subjects diagnosed as AD will be enrolled and treated with Sophora flavescens Aiton topical ointment. After treatment we will estimate the efficacy and record adverse events to conduct statistically analysis. The 1st year project: (1) Expect to enroll 66 clinical subjects of AD. (2) Evaluate subjects 'symptom and proceed herbal ointment treatment. (3) Record treatment responses including adverse effect. (4) Conduct statistically analysis. The 2nd year project: (1) Completing enrollment of 66 clinical subjects of AD. (2) Finish evaluation and treatment of all subjects. (3) Statistically analysis all collecting data (4) Discuss and analyze the outcome.

In order to further improve the diagnosis and treatment level of type 2 inflammatory skin diseases, the National Clinical Center for Skin and Immune Diseases established a standardized diagnosis and treatment center for type 2 inflammatory skin diseases to systematically and effectively understand the current treatment status of patients with type 2 inflammatory skin diseases, as well as the efficacy and safety of various treatment methods during practices, so as to further improve the diagnosis and treatment level of type 2 inflammatory skin diseases and help patients with type 2 inflammatory skin diseases.
