title: [Cold-induced urticaria and angioedema. Classification, diagnosis and therapy].
abstract: The onset of wheals and/or angioedema following the exposure to cold may be associated with a number of different diseases. Most frequently this occurs in cold contact urticaria, a type of physical urticaria, which is characterized by a positive cold stimulation test. The clinical symptoms are based on cold-dependent mast cell activation with subsequent release of proinflammatory mediators. In cases of negative or atypical reaction to cold stimulation testing rare acquired atypical or familiar cold urticaria forms may be suspected. Strict avoidance of cold should be recommended as far as possible. As the underlying causes of cold contact urticaria are widely unknown, the symptomatic use of non-sedating antihistamines is the treatment of first choice. The very rare familiar cold auto-inflammatory syndrome (FCAS) is based on CIAS1/NLRP3 mutations and may be treated effectively by neutralization of pathogenic interleukin 1beta.
