[New therapeutic strategies for the different subtypes of urticaria]

Urticaria is one of the most common skin diseases. It is divided into several categories including acute and chronic urticaria as well as physical urticaria and special subtypes such as cholinergic and autoimmune urticaria. The causes of urticaria are multiple. In more than 80%, urticaria is triggered by an inflammatory focus, a subclinical infection or autoimmune actions. In addition, non-specific pharmacological or toxin-mediated release of inflammatory mediators from basophils or mast cells can also trigger urticaria. These new aspects in the pathophysiology of urticaria suggest new and promising therapeutic strategies. The first line treatment of urticaria still consists of non-sedating H1-antihistamines. Since urticaria has a profound impact on quality of life, effective treatment is very important. We consider new therapeutic options based on our long-term experience in treating patients with urticaria.
