Active clinical trials for "Dermatitis, Atopic"

The aim of the study is to assess the prevalence of peanut, tree nuts, and sesame allergy in Polish children at high risk of food allergy. Additionally, the timing of the development of peanut, tree nuts and sesame allergy in the first three years of life in a high-risk population will be assessed.

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.

Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. This study will assess how safe and effective upadacitinib is in treating AD in adolescent and adult Chinese participants. Upadacitinib is an approved drug for treating AD. Approximately 200 adolescent and adult participants who are prescribed upadacitinib by their physician in accordance with local label will be enrolled in China. Participants will receive upadacitinib as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed up for approximately 24 months per participant and 30 days after last treatment dose for safety data collection. There is expected to be no additional burden for participants in this trial. Participants will attend regular visits during the study at a hospital or clinic according to their routine clinical practice

This is a prospective, open label, uncontrolled study which will be performed in multiple Primary Care (GP) centres, in approximately 60 children (aged 1 year to 15 years) who have moderate atopic eczema and who are not currently using oral or topical corticosteroids or immunomodulators and have not used them in the previous month. Study patients will be asked to use Adex Gel three times daily, for 4 weeks instead of their usual emollient or as the first treatment for their condition, and without supplementary use of any oral or topical steroids or immunomodulators (unless this becomes unavoidable, see section 4.6.3). The Scoring Atopic Dermatitis (SCORAD) assessment will be performed by the investigator/ research nurse at baseline and then after 2 and 4 weeks of treatment. Patients or their parents/ guardians will be asked to complete the quality-of-life questionnaires (Children's Dermatology Life Quality Index (CDLQI) at baseline and after 4 weeks of treatment. Photographs, which will not include any identifiable features or details of the patient, of one eczema affected area will also be taken at baseline and again 4 weeks after treatment.

The purpose of this non-interventional study is to learn about the safety and effectivness of Cibinqo Tablet for the possible treatment of atopic dermatitis (AD). AD is a long-lasting itchy red rash, caused by a skin reaction. This study is seeking participants who: Are patients with moderate to severe AD who have been waiting to start treatment with Cibinqo Have evidence of a personally signed and dated informed consent document indicating that the patient or their parent(s) or legal guardian, have been informed of all important details of the study Investigators will collect and record the information on each participant's experiences with Cibinqo. This study medicine is a tablet which is taken by mouth. Participants will be observed for about a year. During this time, we will study the experiences of people receiving the study medicine to help us decide if the study medicine is safe and effective.

Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Around one-third of patients with AD have had at least 1 incidence of prurigo nodularis (PN), which is characterized by intense, persistent itchy skin and sometimes pain with burning. In this study, the effectiveness of upadacitinib (UPA) will be assessed in participants with prurigo-type AD in a real world (RW) setting in Japan. UPA is an approved drug for the treatment of AD. Adults and adolescents who have been diagnosed with prurigo-type AD and prescribed UPA according to the label and practice in Japan will be enrolled in this observational study. The doctor's decision to prescribe UPA will be made prior to and independently of study participation. Approximately 200 participants will be enrolled in the study at 10 sites in Japan. Participants will receive extended-release oral tablets of UPA once-daily for 48 weeks. There will be no additional burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic.

Single-center, case-control, longitudinal, observational, population based cohort study with stratified sample (by age group, gender, and residential area).

Background: - About 15 million Americans have a food allergy. Because there are no cures or effective prevention or treatment for food allergies, researchers want to learn more about them. Objective: - To learn more about the causes and effects of food allergy and related conditions. Eligibility: People ages 2 99 who have food allergy and/or a related genetic or other condition Their relatives Healthy relatives and volunteers Design: Participants will have at least 3 visits over 1 2 years, and then once a year for up to 12 years. Each may last a day or longer. Participants will be screened with medical history, physical exam, and questionnaires. Participants may have the following: Blood tests Allergy skin prick tests: Drops of allergens are placed on the back or arm. The skin is scratched under each drop. Leukapheresis: blood is taken from a needle in one arm, passed through a machine, and returned through a needle in the other arm. X-rays Esophageal string test: One end of a string is taped to the cheek and the other end is packed into a capsule. When the capsule is swallowed, the string unwinds; it is left in for at least 1 hour. EGD and colonoscopy: Biopsies are taken from the gastrointestinal system. Tiny biopsies of skin Photographs of the body Collection of cells through: Swab of nose, inside of cheek, or skin Gentle skin scrape Tape stripping: piece of tape is put on the skin and pulled off.

The clinical study investigates the long-term course of disease in patients with chronic inflammatory skin diseases (atopic eczema and psoriasis) and the impact of tarheted therapies on the clinical and molecular level. For this purpose, patients are asked to take part in regular examinations and data collections, and to donate biomaterials (blood, skin biopsies, skin swabs, tape strips, stool samples). Blood samples are used to analyze inflammation messengers. Punch biopsies from lesional and non-lesional skin areas are used to analyze gene expression. Tape strips are pieces of transparent adhesive tapes to strip off most of the horny layer that will be used to examine mRNA and protein expression. The skin smears are superficial smears of three areas of skin with cotton swabs, which are used to examine bacteria on the skin. Overall, the study will help to monitor the disease course clinically and on the molecular level in participating patients for at least ten years and to collect information about the impact of various external factors including treatments. The study has no effect on the therapies of the disease, it serves only the accompanying data collection

The BioDay Registry aims to address the need for daily practice data regarding the effectiveness and safety of new systemic treatment options (like biologics and Janus kinase inhibitors) in patients with atopic dermatitis and effect on other atopic comorbidities in a multicenter setting. The registry already consists of several additional modules concerning atopic comorbidities, like food allergy and asthma, and a module for conjunctivitis during biologic treatment.
