Atopic Diathesis in Hypohidrotic/anhidrotic Ectodermal Dysplasia
Keywords:hypohidrotic/anhidrotic ectodermal dysplasia, hypohidrosis/anhidrosis, atopic dermatitis, periorbital eczema
AbstractRecently, patients with hypohidrotic/anhidrotic ectodermal dysplasia (H/AED) have been reported to have a higher prevalence of symptoms suggestive of atopic disorders than the general population. To better understand atopic diathesis in H/AED, 6 cases of clinically or genetically diagnosed H/AED were examined. The following criteria were evaluated with patient consent: sweating, blood test results, histopathology and filaggrin staining. Five of 6 H/AED cases displayed atopic dermatitis-like manifestations, and 3 of these 5 cases experienced periorbital lesions. H/AED patients tended to present with atopic dermatitis-like eruptions with characteristics potentially indicative of periorbital lesions. Atopic diathesis in H/AED appeared not to be associated with filaggrin. We could speculate that hypohidrosis or anhidrosis itself might impair skin barrier function and contribute to atopic diathesis.
