Chronic hives have been called chronic idiopathic urticaria, chronic autoimmune urticaria or chronic spontaneous urticaria. There is also chronic inducible urticaria which can be brought on by cold, delayed pressure, solar, […]

Mast Cell Activation Syndrome (MCAS): Fact & Fiction
Mast cell activation syndrome (MCAS) is a rare condition defined by a severe systemic reaction to mast cell derived mediators. Mast cells are effector cells of the immune system. These cells produce a variety of proinflammatory mediators and participate in a number of different pathological conditions. In patients the risk of developing severe anaphylactic (hypersensitivity) events […]
Cold Hives (urticaria): A review
Cold hives (or urticaria), is a subtype of physical hives that is characterized by the development of hives and swelling in response to cold exposure and rewarming of the skin.

Alternative Agents for Refractory Chronic Urticaria Patients
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) for treating Angioedema and Chronic Hives
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) vs. Omalizumab (Xolair)
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 (Solar Urticaria) Treatment
Sun allergy, also known as solar urticaria, is an uncommon, chronic and disabling form of physical urticaria (hives). Wheals accompanied by itching or burning sensation appear after a few minutes on sun-exposed skin, disappearing after 1 to 2 hours.
