title: Acrodermatitis enteropathica: zinc therapy and possible identification of a carrier state through multiple hair zinc analyses over three decades.
abstract: We report on the successful use of repeated hair analyses over three decades to monitor zinc and copper status in two siblings with Acrodermatitis enteropathica who were treated with oral zinc sulfate beginning in 1975. Furthermore, we report for the first time that analysis of zinc in hair over a 30-yr period allows for the identification of individuals who might be heterozygous carriers of this autosomal recessive disease and who, therefore, would be expected to have hair zinc levels intermediate between normal, healthy individuals and those with Acrodermatitis enteropathica. Zinc treatment of the two patients with Acrodermatitis enteropathica resulted in remission of the signs and symptoms of the disease within the first month of therapy. However, any short-term interruption (typically, 7-10 d) in oral zinc resulted in an almost immediate relapse, with the reappearance of the skin lesions. We also document the inverse relationship that exists between zinc and copper through analysis of these metals in the scalp hair from the two patients, thus providing a tool for ensuring adequate copper intake in patients taking relatively high doses of zinc over a long period.
