Immunoadsorption (IA) has been successfully used in a large variety of autoantibody-mediated disorders. In dermatology, IA is increasingly applied as adjuvant treatment for severe and/or refractory autoimmune bullous diseases. These disorders are characterized by autoantibodies against structural proteins of the skin and/or mucous membranes and include, among others, pemphigus vulgaris, pemphigus foliaceus, and bullous pemphigoid. Autoimmune blistering diseases are associated with a high mortality (pemphigus) or morbidity (bullous pemphigoid) and in particular in pemphigus diseases, treatment is challenging. The pathogenetic role of autoantibodies in most of the immunobullous diseases has been clearly demonstrated, therefore, removal of these autoantibodies is a rational therapeutic approach. IA has been shown to effectively lower the serum autoantibodies and to lead to rapid clinical responses. Most recently, IA has been successfully applied in patients with severe atopic dermatitis and high total serum IgE levels. Here, the different treatment protocols, clinical efficacy, and adverse events are summarized.
