11 Clinical Trials for Various Conditions
Allergic skin reaction can be produced by the combination of a chemical product applied to the skin and ultraviolet (UV) radiation (a type of invisible light that comes from the sun and other light sources and can hurt your skin and eyes) received by the person. The researchers in this study wanted to find out if cream V61-044 might cause an allergic skin reaction to sunlight when applied to the skin in healthy participants. Cream V61-044 (brand name: LOTRIMIN ULTRA) is an approved drug used to treat infections caused by fungi (small growing organisms such as mold, mildew, yeast or mushrooms). Participants joining this study underwent two study phases: in Induction phase, participants received the test cream and UV radiation twice a week for 3 weeks; after 10 days of rest, in Challenge phase participants received the test cream and UV radiation once again. In both phases, the test cream was applied to two test areas on the upper back of the participants and to one of the test area UV radiation was applied. Evaluation on the skin rash was conducted two days after each UV radiation.
This study is designed to evaluate the allergenicity of Amphadase® in healthy volunteers using an intradermal skin test.
The goal of this clinical trial is to determine the sensitization (contact allergy) potential of the test product ColActive Plus Collagen Matrix Dressing after a skin prick test on the skin of healthy human subjects. The main question it aims to answer is: • Does the product induce any sensitization (contact allergy) after a skin prick using a UniTest PC (pain control) device in healthy human subjects? Participants will have the test product and both positive and negative controls applied, and skin response will be evaluated by an allergist at 15 minutes, 6 hours, and 24-48 hours post-application to see if sensitization occurs.
The treatment of allergic contact dermatitis (ACD) can be unsatisfactory, and that other skin diseases such as atopic dermatitis have an increased likelihood of ACD, improved systemic treatments are needed. This research study explores the effectiveness of Baricitinib in treating Delayed-Type Hypersensitivity (allergic) versus Irritant Skin reactions. Subjects for this study need to be healthy males between the ages of 18 and 40. This study will evaluate this by injecting antigens as well as applying them on top of the skin to the forearm then measure the effects of Baricitinib by skin and blood testing.
The aim of this multi-surgeon, single institution study is to prospectively evaluate the incidence of allergic contact dermatitis (ACD) following application of AQUACEL Ag, a silver-containing hydrofiber dressing, in total hip and knee arthroplasty patients. Arthroplasty-naïve patients will be compared to prior total joint arthroplasty patients who received a Aquacel dressing postoperatively.
The purpose of this study is to evaluate the potential of Tazarotene Foam to induce a photoallergic reaction when exposed to UV and VIS light on skin of healthy volunteers.
This study hopes to improve the investigators understanding of how the immune system acts in allergic contact dermatitis. In order to reach this goal, normal volunteers, who are suspected of having allergic contact dermatitis, will be patch tested for the fifteen most common allergens. Then, biopsies will be taken of the skin at the sites where the there is a positive reaction to the allergen. Also, small biopsies will be taken from an area that received a patch but no allergen and an area that did not receive a patch to serve as controls. In a second stage of the study, volunteers will receive patches with the allergen to which they demonstrated an allergic response. More biopsies will be taken, over three designated time points. The biopsied skin samples will then be studied in a laboratory.
Allergy skin tests and allergen immunotherapy are common procedures for both the diagnosis and treatment of atopic diseases. Allergen immunotherapy has proved to be effective in reducing the symptoms of allergic rhinitis and asthma1-2. Despite its clinical benefit, there is risk of systemic reactions associated with these procedures. The systemic reaction rate to skin testing for aeroallergens is significant lower than the rate of reactions to immunotherapy, but it is not negligible. Lin et al reported only 2 patients who had systemic allergic reactions to skin testing for respiratory allergies in 10,400 patients tested.3 They determined the overall risk of inducing anaphylactic reactions by skin testing to be less than 0.02% and other studies have produced similar results.4-5 The rate of systemic reactions to skin testing is likely underscored. Thompson et. al reported a systemic reaction rate of 6% of patients receiving skin testing.6 It is important to recognize the risk of systemic reactions seeing skin testing is commonly done. It is also imperative to recognize the treatments for these reactions to prevent progression. Hypothesis The systemic reaction rate to allergen immunotherapy and skin testing to aeroallergens is higher than previously reported. Biphasic anaphylactic reactions rarely occur with allergen immunotherapy and skin testing.
Single-center, monadic, one day study utilizing the skin prick method to assess the allergy potential of Omeza Collagen Matrix in Human Subjects
This study will explore potential links between atopic dermatitis and food allergy. This information will be useful to determine atopic dermatitis and food allergy share unique biochemical or genetic identifiers useful for diagnosing and treatments in the future. This is a mechanistic study consisting of obtaining blood and skin samples from participants at baseline. Individuals may also undergo a clinically indicated oral food challenge and have blood and skin samples collected at various times during the oral food challenge. This study will create a molecular map of the pathology of atopic dermatitis and food allergy. This information will be deployed to evaluate the hypothesis that atopic dermatitis and food allergy share unique genetic transcriptional signals in which the study team can then further analyze pathological pathways and cell types.
This research study is testing a new way to look for the early stages of anaphylaxis. Eligible participants will have a small monitor (transepidermal water loss) placed on the forearm during a food challenge (for peanut allergies). This monitor continuously records the amount of water lost through the skin. In a previous study the team learned what values are associated with an anaphylactic reaction. These values are called "stopping rules." This study is looking at whether it can use these new stopping rules to end the oral food challenge before a person may show any symptoms.
