Severe hives or chronic spontaneous urticaria is classified as hives with or without swelling that occurs for 6 weeks or more with an unknown cause. The prevalence of chronic hives (also known as chronic idiopathic urticaria) is approximately 0.5% to 5% of the population. Chronic hives may be active for 1-5 years at a time, […]
Chronic urticaria is defined for a period of at least 6 weeks with hives. Patients with chronic urticaria who fail high-dose antihistamines should be referred to an allergy specialist to help manage their condition. We have previously spoke about the stepwise approach to chronic idiopathic/spontaneous urticaria. Stepwise approach to Chronic Urticaria (Chronic Hives) Patients with […]
Omalizumab (Xolair) is being used to treat chronic hives (urticaria). Chronic idiopathic/spontaneous urticaria (CIU/CSU) is characterized by the spontaneous appearance of hives, angioedema or both that recur without specific external stimuli for at least 6 weeks.

Ligelizumab (QGE031) is currently being developed by Novartis for the treatment of allergic diseases mainly asthma and chronic spontaneous urticaria. Allergic diseases are dependent on the development of increased IgE levels. Allergen-specific IgE plays a role in the inflammatory cascade of allergic responses. Allergic individuals with elevated IgE levels have increased allergic mediators (e.g. histamine, […]
Sun allergy, also known as solar urticaria, is an uncommon, chronic and disabling form of physical urticaria (hives).

Chronic idiopathic urticaria or chronic spontaneous urticaria is a condition characterized by itchy hives, swelling or both that recur without a cause for 6 weeks or longer. Its prevalence is between 0.6-0.8% in the general population. We have discussed extensively chronic urticaria in the past http://allergylosangeles.com/allergy-blog/stepwise-approach-to-chronic-urticaria/ and the treatment for it with Xolair http://allergylosangeles.com/allergy-blog/xolair-treatment-duration/. We will now look […]
A big question since Xolair was approved for chronic idiopathic urticaria last year, http://allergylosangeles.com/allergy-blog/xolair-omalizumab-for-chronic-urticaria/ is what should be the Xolair treatment duration for these patients? There have been few studies that have evaluated patients being treated for hives with Xolair for greater than 1 year, since it only has been recently approved. Chronic hives is a […]
