The main purpose of this study is to evaluate the effectiveness of 24 weeks of lebrikizumab in improving disease severity, signs, and symptoms in adults and adolescents with moderate-to-severe atopic dermatitis (AD).

Effects of Treatments on Atopic Dermatitis

Background: \- Atopic dermatitis, or eczema, is a chronic skin disorder. Patients sometimes have infections with S. aureus bacteria. Researchers want to study how eczema treatments affect the number and the type of bacteria on the skin. Objectives: \- To study the effect of eczema treatments on skin bacteria. Eligibility: * Individuals between 2 and 25 years of age who have moderate to severe atopic dermatitis. * Healthy volunteers between 18 and 40 years of age with no history of eczema. Design: * Participants will be screened with a physical exam and medical history. Research samples will be collected. Skin biopsies may also be performed. * All participants will be assigned to one of several study groups. * Healthy volunteers must not have taken antibiotics in the year before the start of the study. * All participants will have regular study visits during their 1-year participation. More research samples will be collected at these visits. * Healthy volunteers may be asked to come in for a one-time follow up after the 1 year mark.

Studies of Skin Microbes in Healthy People and in People With Skin Conditions

This study will examine microbes (e.g., bacteria, fungi, viruses) that live on human skin and how microbes contribute to health and disease. It will analyze healthy human skin and how the these microorganisms might change in patients with atopic dermatitis (AD), a skin condition also known as eczema. Healthy volunteers, as well as patients with moderate to severe eczema (AD), between 2 and 40 years of age may be eligible for this study. We also wish to enroll children and adults aged 2-40 who have been diagnosed with inherited immune disorders known as HIES (hyperimmunoglobulin-E syndrome), WAS (Wiskott-Aldrich syndrome), or DOCK8 immunodeficiency because they frequently have skin problems similar to AD. Eligible participants undergo the following tests and procedures: * Medical family and medication history * Skin examination * Blood tests (research blood as well as serum IgE, and complete blood count) * Skin samples to analyze microbes. Samples are obtained by the following methods: swabbing the skin with a cotton swab; scraping (scratching) the skin gently with a blade to remove only the outermost skin layers; and, only in adults, biopsy (surgical removal) of a small skin sample less than 1/4-inch (5 mm) in diameter. * Nose swabs to analyze microbes. * Patients with eczema may have photographs of their skin taken to help monitor the skin rashes. Participants may be contacted periodically for follow-up studies. Patients with atopic dermatitis may have additional skin samples collected to examine changes in the skin bacteria over time and during all of the stages of eczema. In addition, patients who have a flare of their eczema are asked to undergo a skin sample collection as soon as possible.

Sodium in the Skin and Atopic Dermatitis

The goal of this observational study is to understand factors associated with skin sodium storage in healthy adults and people with atopic dermatitis ages 50 and above. The study is designed to test whether diet and skin barrier function are associated with skin sodium concentration and whether skin sodium concentration is linked to atopic dermatitis and immune profiles over time. Participants will be asked to complete questionnaires, provide bio samples, and undergo non-contrast sodium MRI at 2-3 time points over 3-24 months.

A Study to Learn About Abrocitinib in Adult Patients With Moderate to Severe Atopic Dermatitis.

The purpose of this study is to learn about the safety and effects of Abrocitinib in the real-life clinical setting given for the treatment of moderate to severe atopic dermatitis. Atopic dermatitis, or AD, is a long-lasting disease that causes inflammation, redness, and irritation of the skin. This study is seeking participant who are older than 18 years with moderate-to-severe chronic AD. Participants must have no underlying medical conditions that prevent them from taking Abrocitinib. All participants in this study will receive Abrocitinib as a tablet once daily. They can take Abrocitinib and use medicated topical treatment for AD at the same time. We will examine the experiences of patients receiving the study medicine. This will help us determine if the study medicine is safe and helps in treating AD. Participants will take part in this study for 24 months. During this time, they will visit the study clinic about 5 times (about 1 time every 4 to 6 months).

Abrocitinib Taiwan Treatment Pattern and Real World Study in ATopiC Dermatitis (ATTRACT Registry)

Use of a Digital Psychotherapeutic App to Reduce Symptom Burden in Dermatology Patients

Skin diseases, despite low mortality, significantly impair quality of life. This randomised controlled trial evaluates the efficacy of a digital toolkit comprising psychotherapeutic strategies in reducing QoL burden in patients with chronic inflammatory skin conditions. This toolkit is hosted on a mobile application and will be used by study participants randomised to the intervention arm over the 32 week study period.

A Randomised Controlled Trial of ePROM-Guided Flexible Scheduling in Dermatology

The goal of this clinical trial is to evaluate whether an electronic patient-reported outcome measure (ePROM)-guided flexible scheduling system can improve outpatient clinic resource utilisation in patients attending dermatology outpatient clinics for routine follow-up. The main questions it aims to answer are: * Does the intervention reduce the number of actualised outpatient visits over 12 months compared with standard fixed scheduling? * Does the intervention group achieve higher adherence to monthly ePROM monitoring, as measured by the proportion of completed ePROM submissions?

A Real-world Study of Deucravacitinib in the Treatment of Moderate to Severe Plaque Psoriasis With Eczematous Features

Emerging evidence indicates that psoriasis and eczema can coexist in the same patient, with reported co-prevalence rates ranging from 0.17% to 20%, suggesting that these conditions may represent a disease spectrum-referred to as Psoriasis Eczema (PsEma). Moreover, paradoxical eczema has been observed in approximately 1% to 12.1% of psoriasis patients undergoing biologic therapy, with up to 61% of affected individuals discontinuing treatment due to eczematous flares. These findings underscore an urgent need for therapeutic agents that are efficacious for PsEma. Tyrosine kinase 2 (TYK2), a member of the Janus kinase (JAK) family, is known to mediate critical signaling pathways involved in psoriasis pathogenesis, including those of type I interferons, interleukin (IL)-12, and IL-23. Additionally, TYK2 forms heterodimers with other JAK family members-such as JAK1 or JAK2-to transduce signals from cytokines like IL-13 and IL-22, which are centrally implicated in the pathophysiology of eczema. Based on this molecular profile, we hypothesize that TYK2 inhibition may not only avoid inducing eczematous reactions in psoriasis patients but may also alleviate eczematous inflammation by interfering with JAK1(JAK2)/TYK2-mediated IL-13 and IL-22 signaling. Deucravacitinib, a selective allosteric TYK2 inhibitor, has shown promising results in our clinical practice, demonstrating improvements in both psoriatic and eczematous manifestations among patients with PsEma. This study aims to prospectively evaluate the efficacy and safety of deucravacitinib in PsEma patients over a 16-week treatment period. In parallel, transcriptomic profiling of peripheral blood and lesional skin will be performed to elucidate the immunological landscape and molecular signatures underlying PsEma, thereby contributing valuable clinical and mechanistic insights into its diagnosis and management.

The Impact of Dietary Salt on the Severity of Eczema

The goal of this clinical trial is to evaluate the feasibility of low-sodium diet to improve eczema severity. The main questions it aims to answer are: * Does a low-sodium diet improve eczema severity? * How does a low-sodium diet impact skin sodium concentration? * Is skin sodium concentration associated with eczema severity? Researchers will ask all participant to follow a low-sodium diet, then 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 24-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 * Complete up to 4 virtual check-in visits * Visit the clinic 4 times to answer questionnaires, provide bio samples, complete dietary recalls, and undergo non-contrast sodium MRI

Cardamom and Topical Roseomonas in Atopic Dermatitis

Background: Atopic dermatitis (AD), also called eczema, is a chronic skin condition. AD can make skin dry and itchy, and sometimes it can lead to serious health problems, such as asthma, food allergies, eye infections, and sleep problems. No cure exists for AD. Researchers know that people with AD have different kinds of harmless bacteria on their skin than do people without AD. They want to see if adding a harmless bacteria (Roseomonas mucosa) to the skin can help people with AD. Objective: To test a skin treatment that contains R. mucosa and ground cardamom seeds in people with AD. Eligibility: People aged 2 years and older with AD. Design: All study visits will be remote. Participants will have 5 visits over about 7 months. Participants will be screened. Researchers will review their AD and medical history. Participants will receive a study product in the mail. The product comes as a powder in single-use packets. Participants will be shown how to mix the powder with water in a single-use spray vial. They will spray the solution onto their skin 2 to 3 times per week for 14 weeks. Half of participants will receive the study powder. Half will receive a placebo; the placebo looks just like the study powder but contains no bacteria. They will not know which one they have. During 3 study visits, participants will take a skin swab. They will receive supplies in the mail to rub a cotton swab on their skin and mail it back to the researchers. Participants may opt to have pictures taken of their AD. Participants will fill out 4 online questionnaires.

Fish Oil Supplementation During Pregnancy for Prevention of Asthma, Eczema and Allergies in Childhood

The aim of this study is to prevent asthma and allergies in childhood by supplementation with fish oil (n-3 fatty acids) to the mother during pregnancy. Paticipants are mother and children participating in the ABC-(Asthma Begins in Childhood)cohort. Mothers are recruited during pregnancy and receive supplement with n-3 fatty acids or olive oil (placebo) from week 24 of gestation to 1 week after delivery. The child is followed with acute and planned visit at the research unit and diagnosis of disease is done in the research unit according to predefined algorithms.

Dermoscopy and UVFD in Differentiating Palmoplantar Psoriasis and Palmoplantar Eczema

Palmoplantar psoriasis and palmoplantar eczema are chronic inflammatory skin diseases that may show similar findings on the palms and soles, such as redness, scaling, thickening of the skin, fissures, itching, and burning. Because these conditions can look alike, distinguishing between them in routine clinical practice may be difficult. This prospective, single-center observational study was designed to compare polarized dermoscopic and ultraviolet-induced fluorescence dermoscopic (UVFD) findings in adult patients with palmoplantar psoriasis and palmoplantar eczema. A total of 81 patients aged 18 years and older were included: 41 patients with clinically and/or histopathologically confirmed palmoplantar plaque psoriasis and 40 patients with palmoplantar eczema. Dermoscopic and UVFD images were evaluated to identify vascular, scaling, surface, and fluorescence-related features that may help differentiate palmoplantar psoriasis from palmoplantar eczema. The study aims to assess whether these non-invasive imaging methods can provide additional diagnostic clues to support clinical evaluation.

This is a Phase 2, randomized, double-blind, vehicle-controlled clinical study evaluating the efficacy and safety of GX-03 topical ointment in adult subjects with moderate to severe atopic dermatitis (eczema). The study plans to enroll up to 120 eligible patients with a target of at least 100 completing the study and an ability to expand enrollment up to 200 subjects based on a pre-specified interim assessment conducted by an Independent Data Monitoring Committee (IDMC). Subjects will be randomized in a 1:1 ratio to receive either GX-03 or vehicle control for 8 weeks. The study is designed to evaluate improvement in investigator-assessed disease severity, itch, and patient-reported eczema symptoms following topical treatment with GX-03 compared with vehicle control. Efficacy assessments include the Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD™), Eczema Area and Severity Index (EASI), Peak Pruritus Numeric Rating Scale (PP-NRS), and Patient-Oriented Eczema Measure (POEM). An interim assessment of conditional power for the primary efficacy endpoint will occur after the first 50 subjects complete the Week 8 visit or withdraw prematurely. Based on pre-specified criteria defined in the IDMC Charter, the IDMC may recommend continuation as planned, expansion of enrollment up to 200 subjects, or early curtailment of enrollment.

Impact of a Daily Application of an Omega-3 Monoglycerides Based Serum and Cream on the Skin Microbiota

This exploratory study aims to investigate the prebiotic potential of daily application of an omega-3 serum and cream to skin affected by eczema. The study will also collect data on any potential adverse effects of the products. Ten subjects will be enrolled in the study and will receive the same treatment for fourteen days. Their baseline condition before treatment will serve as a control for the effects observed after treatment on the targeted eczema area. A second area of eczema treated with the patient's usual skincare routine will also serve as a control.

Skin Inflammation in (Peri)Menopause: A Probiotic Intervention Proof of Concept Trial

This study will explore whether a daily probiotic drink containing Lactobacillus casei Shirota (LcS) can help improve immune function and reduce inflammation in women going through the menopausal transition. Hormonal changes during this stage of life can affect the immune system, gut health, and skin, sometimes leading to increased inflammation or conditions such as eczema, acne or rosacea. Participants will consume either a low-sugar LcS probiotic drink or a skimmed milk control drink every day for eight weeks. The study will assess markers of immune ageing, inflammation, skin health, wellbeing, and hormone levels. The results will help determine whether a safe, non-hormonal probiotic approach may support immune and skin health during the menopausal transition.

This research study is being conducted to find out if the test medicine, abrocitinib, improves eczema and is safe for children 6 to \<12 years of age who have moderate-to-severe eczema. Research study participants who meet the study criteria will be assigned by chance (like the flip of a coin) to receive either abrocitinib test medicine or placebo (pretend medicine that looks just like the test medicine) for 16 weeks. The study will last for about 24 weeks in total.

The Skin Microbiota in Skin Disease and Eczema

Background: The skin microbiota influence skin health in several skin diseases and atopic dermatitis (AD). Presence of Staphylococcus have been associated to a sever course of the disease. Objectives: The aim of the study is to investigate the influence of bacteria, and the skin microbiota on the inflammation and skin barrier. Moreover, dysbiosis in the microbiota, the inflammation profile, the skin barrier damage will be related to objective and patient oriented measures. Importance: Knowledge of interactions between host defense, skin barrier and bacterial colonizing skin can facilitate development of new prevention and treatment strategies to control microbial impact in skin diseases and eczema.

Defining the Skin and Blood Biomarkers of Pediatric Atopic Dermatitis

Atopic dermatitis (AD), also known as eczema, is the most common inflammatory skin disorder of children, affecting 10-20% of children and 1-2% of adults. This skin disorder can be associated with unbearable itchiness and an increased susceptibility to skin infections. The cause of AD is currently poorly understood; therefore, there are no targeted treatment options at present. There have been recent studies in adults with AD that explain the cause and give us new routes to investigate treatment options, however no major studies in this arena have been done in children. We hope to evaluate the skin and blood biomarkers that are found in pediatric AD and compare them to adult AD. Hypothesis: The immune system worsens the skin barrier issues that are common in atopic dermatitis. We believe there are similar immune and skin abnormalities in adult versus pediatric atopic dermatitis. Finally, blood levels of the activated molecules in atopic dermatitis can serve as surrogates for skin immune activation and will correlate with disease severity.

Investigation of Filaggrin Gene Mutations Among Latinx Patients With Atopic Dermatitis

The study, Investigation of Filaggrin Gene Mutations among Latinx patients with Atopic Dermatitis, will examine the association between pathogenic FLG LOF variants and AD in a new population of Latinx patients for which clinical and disease characteristics will be well-described.

Omega-3 Monoglyceride Based Topic Products as Skin Prebiotics for Eczema

This exploratory study aims to verify the impact on the severity of eczema as well as the prebiotic potential of a daily application of Omega-3 serum and cream on a skin with eczema. This study will also collect data on possible adverse effects of the products. Sixteen participants will be enrolled in this study and will be divided in two groups of 8 subjects that will receive two different treatments for forty-two days. The baseline condition will serve as a control for the effects observed after treatment on the targeted eczema area.
