Diagnostic and therapeutic iter in chronic urticaria patients

We describe a diagnostic and therapeutic protocol for the management of chronic urticaria. It is derived from an extensive review of current literature, with a cost-effective evaluation of laboratory investigations and therapeutic approaches. Our protocol may not represent a cornerstone for chronic urticaria: much has in fact to be clarified on pathogenetic mechanisms and aetiological factors. Nevertheless, its application should be able, in our opinion, to identify what is useful or not in the everyday management of chronic urticaria patients.
