Acrodermatitis enteropathica is an autosomal recessive metabolic disorder affecting the uptake of zinc, characterized by periorificial (around the natural orifices) and acral (in the limbs) dermatitis, alopecia (loss of hair), and diarrhea.
The defect is in a gene that encodes a transmembrane protein that helps the body take in zinc.
Features of acrodermatitis enteropathica start appearing in the first few months of life, as the infant discontinues breast milk. There are erythematous patches and plaques of dry, scaly skin. The lesions may appear eczematous, or may evolve further into crusted vesicles ,bullas or pustules. The lesions are frequent around the mouth and anus, and also in hands, feet and scalp.
Without treatment, the disease is fatal and affected individuals may die within a few years. There is no cure for the condition. Treatment includes lifelong dietary zinc supplementation in the range of greater than 1-2 mg/kg of bodyweight per day. (adapted from wikipedia)Other similar posts
