Workup

  • Treatment of urticaria can be very difficult. There are no guaranteed treatments or means of controls. Some people are treatment resistant. Medications can spontaneously lose effectiveness, requiring new medications to control attacks.[allergydoc.us]
  • Treatment of urticaria Acute urticaria The primary treatment in acute urticaria is to avoid the trigger, if it is known to be an acute allergic or inducible urticaria.[allerg.qc.ca]

Pathophysiology

  • We suggest that circulating histamine-releasing factors, probably represented by histamine-releasing autoantibodies, might be involved in the pathophysiology of both chronic urticaria and asthma.[ncbi.nlm.nih.gov]
  • In cases when the condition persists for weeks or months, this is called chronic idiopathic urticarial (or CIU) Pathophysiology: Hives are mediated by cells in the superficial skin called Mast Cells.[allergypartners.com]
  • The pathophysiology of urticaria is an inflammatory reaction in the skin, causing leakage of capillaries in the dermis, resulting in an edema which persists until the interstitial fluid is absorbed into the surrounding cells.[allergydoc.us]

  • The best way to prevent hives is to discontinue exposure to the allergic irritant. Hives lasting more than six weeks are known as chronic urticaria or, if there is swelling below the surface of the skin, angioedema.[skincarecenterderm.com]
  • If the hives feel itchy, the doctor may recommend an antihistamine medicine to block the release of histamine in the bloodstream and prevent breakouts.[kidshealth.org]
