cold urticaria

Cold urticaria is common and lasts for an average of five to six years.

This is different than the normal redness that can be seen in people without cold urticaria.

Patients with cold urticaria need to learn to protect themselves from a hasty drop in body temperature.

Ebastine has been proposed as an approach to prevent acquired cold urticaria.

A distinct hive should develop if a patient suffers cold urticaria.

Cold urticaria may be divided into the following types:

Cold urticaria is diagnosed by dabbing an ice cube against the skin of the forearm for 1 to 5 minutes.

Mutations in this gene also cause familial cold urticaria and Muckle-Wells syndrome.

The common form of cold urticaria demonstrates itself with the rapid onset of hives on the face, neck, or hands after exposure to cold.

Reflex cold urticaria is a cutaneous condition in which generalized cooling of the body induces widespread whealing.

There are two forms of the disorder: essential (acquired) cold urticaria, and familial (hereditary) cold urticaria.

Cold Urticaria (essentially meaning "cold hives") is an allergy where hives (urticaria) or large red welts form on the skin after exposure to a cold stimulus.

This disorder, or perhaps two disorders with the same clinical manifestations, can be inherited (familial cold urticaria) or acquired (primary acquired cold urticaria).

FCAS shares symptoms, and should not be confused, with acquired cold urticaria, a more common condition mediated by different mechanisms that usually develops later in life and is rarely inherited.

Urticaria Idiopathic Cold (Familial or Acquired) Primary Idiopathic Cold Urticaria Cold rrticaria is a chronic, reactive skin disorder.

The symptoms of the acquired form become obvious in two to five minutes after exposure to the triggering substance or situation, while it takes 24 to 48 hours for symptoms of familial cold urticaria to appear.

The disease is caused in 60% of cases by a mutated gene called CIAS1 that is known to be involved in other syndromes that appear somewhat similar, such as Muckle-Wells syndrome and familial cold urticaria.

This protein is part of an inflammatory pathway associated with other autoinflammatory diseases such as familial Mediterranean fever, Hyperimmunoglobulinemia D with recurrent fever, Muckle-Wells syndrome, neonatal onset multisystem inflammatory disease and familial cold urticaria.

Familial cold urticaria (also properly known as familial cold autoinflammatory syndrome, FCAS) is an autosomal dominant condition characterized by rash, conjunctivitis, fever/chills and arthralgias elicited by exposure to cold - sometimes temperatures below 22 C (72 F).

MWS is closely related to two other syndromes, familial cold urticaria and neonatal onset multisystem inflammatory disease - in fact, all three are related to mutations in the same gene and subsumed under the term cryopyrin-associated periodic syndromes (CAPS).

Autographism Physical Allergy Urticaria Aquagenic Urticaria Cold Urticaria Dermatographia Dermographism Physical urticaria is a condition in which red (erythematous) allergic skin lesions and itching (pruritus) are produced by exposure to heat, cold, or contact with chemicals or plants.
