Epidermal Mediators for Lymphocytes in Contact Eczema

  • Conference paper
Current Topics in Contact Dermatitis

Summary

A total of 56 persons were studied for the presence of epidermal mediators in tuberculin skin tests, allergic patch tests, or irritant reactions from sodium lauryl sulphate (SLS) 3%. Epidermis was obtained with the suction blister technique, homogenized, dialysed, and ultrafiltered, leaving substances larger than 3 kDa for further studies. The epidermal homogenate was assayed for interleukin-1 (IL-1) activity and for the presence of epidermal lymphocyte chemotactic factor (ELCF). Our results show that simple occlusion of the skin in non-eczematous persons does not induce any significant amount of mediators. However, if the person in question suffers from irritant eczema, then occlusion per se will induce a significant amount of ELCF, but not IL-1. Both mediators are induced following a cell-mediated immune reaction in the skin irrespective of the presence of eczema. In patients with cutaneous allergy, the mediators are expressed in normal-looking, non-tested skin, when an allergic patch test is applied elsewhere. This may in part explain the excited skin syndrome.
