Active clinical trials for "Dermatitis"

Atopic dermatitis (AD) is a chronic type of eczema affecting approximately 10% of adults and 12% of children in the US. The intense itching (pruritus) associated with AD can be significantly disruptive to sleep and quality of life for both the patients and their caregivers. AD is challenging to describe and measure. The purpose of this study is to see if we can reliably measure how much people with AD scratch and how scratching interferes with sleep and quality of life by using digital sensors, sleep studies and patient-reported information.

The objective of this study is to investigate the potential of NeoMatriXTM Wound Matrix to cause an allergic response to healthy volunteers using a skin prick test.

The purpose of this trial is to evaluate the phototoxic potential of a single application on healthy skin of LEO 29102 cream in different doses.

THe study seeks to determine if pimecrolimus has a positive effect on increasing antimicrobial peptide expression and reducing vaccinia virus growth in the skin explants from patients with atopic dermatitis.

The use of a suction blister apparatus has facilitated study of the immunologic capacity of human epidermal cells. We have been able to prepare purified populations of these cells after blister formation. Specifically, using the blister tops, we are able to enrich for epidermal Langerhans cells which are very potent stimulators in antigen presenting assays. Thus, this normal volunteer study provides an important source of fresh epidermal tissue from which we can study normal epidermal Langerhans cell function. In addition, we have recently used blister roofs in important experimental models of HIV-1 transmission. There is no other method available for assessing the biologic function of freshly isolated Langerhans cells without altering their milieu. It is a very safe and effective way to obtain human epidermal samples.

Cytokine Production Patterns in Patients with Systemic Mastocytosis Compared with Atopic Dermatitis and Healthy Individuals Summary: This study will examine how mast cells (cells involved in allergic reactions) migrate and multiply in the skin of patients with mastocytosis, a condition characterized by too many mast cells in the body. The mast cells tend to multiply in the skin, causing dark, itchy skin spots known as urticaria pigmentosa. This study will determine if the skin of patients with mastocytosis produces chemicals called cytokines that cause mast cells to migrate to the skin and multiply. The findings will be compared with those from normal volunteers and patients with atopic dermatitis, a skin disease characterized by recurrent itchy rash usually seen in people with a family history of allergies. Healthy volunteers, patients with mastocytosis and patients with atopic dermatitis 18 years of age and older may be eligible for this study. Participants will have the following tests and procedures: Suction blisters - Two to eight small blisters will be raised on the forearm using gentle suction. The fluid in the blisters will be collected with a syringe to study the chemicals produced by the skin. The tops of the blisters may be removed for research. Template study - Patients with high cytokine content in the blister fluid may have a template study. For this procedure, a plastic block (template) with holes matching the blister sites is placed over the blistered area. The wells of the template are filled with salt water and the fluid is removed with a syringe at 3, 8 and/or 24 hours. Patients are hospitalized for 24 hours for this study. Skin biopsy - A skin biopsy will be done to correlate cytokine levels with the number of mast cells in the skin. An area of skin is numbed with an anesthetic and a small circular area about the size of a pencil eraser is removed, using a sharp cookie cutter-type instrument. Blood draw - About 4 tablespoons of blood will be drawn to compare the chemicals in the blood with those in the blister fluid. The blood will also be analyzed for a complete blood count, clotting factors and substances that may be elevated in people with allergies.

Atopic dermatitis represents a real challenge in public health as it affects a large percentage of children and adults. Affected individuals must cope with a significant psychosocial burden, in addition to dealing with the medical aspects of the disease. The purpose of this exploratory study is to collect clinical severity AD data, using PO-SCORAD (self-assessment by the subjects), SCORAD evolution, instrumental measurements and treatment follow up of subjects. The future objective is to develop a personalised prediction model of AD flares in order to improve management of AD by more accurate severity evaluations by the subject and the physician. Development of a method of early detection of flares will open new treatment pathways for AD management.

The impact of tailored patient-provider communication to improve clinical trial recruitment, patient knowledge, and patient engagement will be studied. Tailored patient-provider communication refers to the individualization of patient-provider communication using patients' preferred methods of communication. This involves the utilization of social messaging such as e-mail or text and/or social media platforms. These communication methods purport to and meet individual patient needs whilst ensuring that information is received and in a format that is familiar to each patient. The primary outcomes of the proposed research is to evaluate the impact of tailored patient-provider communication on patient response rates (speed and number), clinical trial recruitment rates, patient knowledge, and patient engagement.

Observational, descriptive, retrospective, multicenter study to evaluate the safety of the treatment with Sebryl® and / or Sebryl Plus® in the management of seborrheic dermatitis and psoriasis of the scalp in routine medical practice.

This non-intervention study will identify the biomarker profiles in hidradenitis suppurativa (HS) and atopic dermatitis (AD) (as a comparator) that would have the most utility in interventional studies evaluating efficacy during therapeutic intervention. Study data will also be used to correlate cellular/molecular changes in blood (cells and serum), and tissue, with clinical/histopathological phenotypes.
