Diclofenac-Induced Allergic Contact Dermatitis: A Series of Four Patients
Allergic contact dermatitis is an immune-mediated antigen-specific skin reaction to an allergenic chemical that corresponds to a delayed-type hypersensitivity response (type IV reaction). Allergic contact dermatitis should be suspected when skin lesions are localized to the site of previous applications of the culprit drug. Lesions appear after re-exposure in susceptible persons, with delayed o...
متن کاملPatch test results in patients with suspected allergic contact dermatitis: a study from Mashhad, Iran and a review of literature
Background: The standard patch test is known as the most reliable test to identify and confirm causative agents of allergic contact dermatitis (ACD). Previous studies have shown that the prevalence of specific allergens varies by geographic area. The results of patch test in patients visiting our dermatology clinics with suspected ACD were prospectively investigated and compared with those repo...
متن کاملAllergic Contact Dermatitis Physiology
Allergic Contact Dermatitis (ACD) involves the penetration of an allergen through the skin surface where it acts as a hapten by binding to epidermal proteins and eliciting, a delayed Type IV hypersensitivity reaction 48 to 120 hours after exposure. This immunologic response involves the activation of Th1 cells with the subsequent release of cytokines resulting in the classic inflammatory reaction.
متن کاملAllergic contact dermatitis
Allergic contact dermatitis is a T cell mediated, antigen-specific inflammatory reaction of the skin due to repeated epicutaneous exposure to antigens. Immunologically it is divided into 2 phases, induction and elicitation phase. During the first phase which is clinically silent, naïve T cells are activated and differentiate into antigen-specific memory T cells. During the elicitation phase, af...
متن کاملAllergic contact dermatitis.
Allergic contact dermatitis (ACD) is a common occupational and environmental health issue. In common with other forms of allergy the disease progresses in two stages; an initial phase during which sensitization is acquired, followed later (after subsequent exposure to the same chemical allergen) by elicitation of a cutaneous inflammatory reaction. The development of skin sensitization is associ...
