A specific cause is identified in approximately one-half of patients with acute urticaria and one-quarter of patients with chronic urticaria.An episode of urticaria is identified by highly pruritic, well-defined, pink-to-red wheals, often with a pale centre (Figure 3), which usually last no more than 48 hours and leave no remaining marks.
Individual episodes usually resolve within a two hour period, but physical urticaria often persists as a chronic, recurring condition.In a study of 356 patients with urticaria referred for allergy and immunology evaluation, only one patient benefited from a change in management due to testing and only 319 (17%) of the 1872 tests ordered had abnormal findings.The choice of investigations should be guided by positive findings from the clinical history and physical examination.Urticaria is a common condition, which is usually non-allergenic, but in the majority of patients a specific cause will not be found.Extensive diagnostic testing is not recommended unless there is strong evidence to suspect a specific trigger.Most cases of urticaria are acute, however, in some cases, episodes may occur over several months or even years.
Urticaria is a common condition, in which the majority of cases are non-allergenic.Approximately 40% of people with urticaria also have signs of angioedema.Angioedema involves the deeper epidermis and subcutaneous tissues and most frequently affects the eyes, mouth, throat, tongue, hands and feet.Treatment is aimed at symptom relief, using oral non-sedating antihistamines first-line.Additional medicines can be added, depending on the severity and duration of symptoms.A focused clinical history and physical examination are the most useful tools when diagnosing and treating urticaria.
