Background. Allergic Contact Dermatitis (ACD) is an inflammatory skin disease mediated by direct contact with allergens as nickel, the most common allergen, that may be related with epigenetic changes. Objective. Evaluate the miR-126 expression and its target VCAM-1, in the skin of patients with ACD to nickel. Methods. Fifteen patients with positive patch test to nickel were included, and the expression of miR-126 and VCAM-1 was evaluated by RT-qPCR.
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.
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 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.
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.
