Filter by:Nickel (Ni)-mediated allergic contact dermatitis (ACD) is a very common disease worldwide. Our previous findings demonstrated that in vitro supplementation of polyphenols, extracted from seeds of red grape (Nero di Troia cultivar), to peripheral lymphomonocytes from Ni-mediated ACD patients could reduce release of T helper (h)1 [interferon (IFN)-] and Th2 [interleukin (IL)-4] cytokines, on the one hand. On the other hand, IL-10 (an anti-inflammatory cytokine) levels increased with a reduction of IL-17 (an inflammatory cytokine). Also levels of nitric oxide (NO) decreased in response to polyphenol pretreatment.
The purpose of this study is to evaluate the safety and efficacy of EB01 Cream (0.2%, 1.0%, 2.0%) applied twice per day (BID) for the treatment of moderate to severe chronic allergic contact dermatitis (ACD). The purpose of the open label extension is to assess the long-term safety, tolerability, and efficacy of EB01 2.0% cream in subjects with moderate to severe chronic allergic contact dermatitis.
The primary objectives of this study are to identify positivity rates to three novel surfactants (ingredients used in soaps, detergents, and other cleansers that serve to lower the surface tension of the skin and remove debris) and co-reactivity with other surfactants in patients with known surfactant sensitivity on skin patch testing. The investigators hypothesize that subjects who previously tested positive to known allergenic surfactants (cocamidopropyl betaine, stearamidopropyl dimethylamine, dimethylaminopropylamine, coconut diethanolamide, oleamidopropyl dimethylamine, and decyl glucoside) may demonstrate co-reactivity to the three novel surfactant sensitizers (sodium lauroyl sarcosinate, isostearmidopropyl morpholine lactate, and disodium lauroamphodiacetate) on skin patch testing.
The purpose of this study is to compare the allergen ethylenediamine dihydrochloride when prepared using methylcellulose versus preparation using polyvinylpyrrolidone.
The objective of the study was to evaluate the diagnostic performance and safety of T.R.U.E. Test allergens in pediatric subjects aged 6-17 years old. In total, 11 allergens were evaluated; 7 new allergens on panels 2.2 and 3.2 and 4 previously approved allergens for which changes were made to dose and excipient.
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.
Nickel contact dermatitis (eczema) is one of the most common allergic conditions affecting the skin. This is a study looking at potentially desensitizing nickel-allergic patients to their allergy using anti-inflammatory ointments applied to the skin (arm). Application of these ointments (ie. modified Vitamin D) has been shown to increase specific immune cells (T regulatory cells), which play a role in preventing immune activation and subsequently inflammation. The investigators propose use of topical anti-inflammatory agents (corticosteroids, modified Vitamin D, or both) may desensitize patients with nickel allergy.
The purpose of the study is to assess the effect of a single dose of NI-0801 on the severity of nickel-induced allergic contact dermatitis.
The objective of this study is to evaluate the efficacy of apremilast in patients with recalcitrant atopic or contact dermatitis.
A Double-blind, Vehicle-controlled Study to Assess the Safety, Tolerability, and Efficacy of Three Weeks of Daily Dermal Application of MRX-6 or steroid on the Treatment of Mild to Moderate Allergic Contact Dermatitis of the Hand and Forearm. Total number of patients: up to 80.
