Deterrence/Prevention
If a precipitating factor is identified, patients should be advised to avoid it. Certain medications, such as aspirin and nonsteroidal anti-inflammatory drugs, are reported to exacerbate urticaria in patients with chronic urticaria resulting from other causes.
Complications
Lesions of urticaria should resolve without complication; however, patients with severe pruritus may develop scratch purpura and excoriations that may become secondarily infected. Additionally, antihistamine use may cause somnolence and dry mouth. Finally, patients with severe disease may be impacted by quality-of-life issues.
Prognosis
Most patients with chronic idiopathic urticaria have resolution of symptoms within 3 years from the onset of symptoms; 86% are symptom free at 5 years. The presence of anti–immunoglobulin G or antithyroid antibodies may worsen the prognosis. Chronic urticaria impairs quality of life to the extent experienced by persons with severe coronary artery disease. Chronic urticaria can lead to significant psychological stress, and the converse is also recognized. A possible mechanism is through stress-induced release of corticotrophin-releasing hormone (CRH), which is known to be expressed in the skin. Up-regulation occurs of the CRH-R1 receptor that mediates CRH-dependent cutaneous mast cell degranulation in chronic urticaria.[30]
Chronic idiopathic urticaria may be less uncommon in children, but it appears to have a similar pathogenesis and a favorable prognosis, with resolution in half of the children within 5 years. Girls older than 10 years may have a less favorable prognosis.[31]
