Red Grape Polyphenol Oral Administration to Women Affected by Nickel-mediated Allergic Contact Dermatitis

Nickel (Ni) is a transitional metal largely distributed in the environment whose continuous exposure is able to provoke local and systemic allergic contact dermatitis (ACD). Ni-mediated ACD is characterized by loss of epidermal integrity, urticaria/angioedema, flares, and itching, whose extent depends on many variables such as genetic, time of sensitization and environmental exposure.The aim of the present research is to verify whether the oral administration of polyphenols (NATUR-OX®) to patients with Ni-mediated ACD is able to modify immune parameters.
