Journal; Kaplan A, Ledford D, Ashby M, et al. Omalizumab in patients with symptomatic chronic idiopathic/spontaneous urticaria despite standard combination therapy.

Acute urticaria can occur in newborns and infants but is uncommon. Acute urticaria in children is usually caused by infection, even if afebrile. In older children food, medication, and inhaled allergens are also important causes. In adults urticaria is usually idiopathic and spontaneous. Acute urticaria with fever can be the first sign of COVID ...

Chronic spontaneous urticaria is mainly idiopathic (cause unknown). An autoimmune cause is likely. About half of investigated patients carry functional IgG autoantibodies to immunoglobulin IgE or high-affinity receptor FcεRIα. Chronic spontaneous urticaria has also been associated with:

Physical urticaria. Physical urticaria accounts for 50% of cases of urticaria and may coexist with idiopathic chronic urticaria. Physical urticaria results in localised short-lasting weals (less than one hour). Physical urticaria may be due to: Light touch (dermographism) Pressure, heat; Cold; Sweat (cholinergic) Water (aquagenic) Sunlight (solar)

Psychotherapy is reported to benefit some patients with chronic urticaria. Avoidance of trigger factors. In addition to antihistamines, the cause of urticaria should be eliminated if known (eg drug or food allergy). Avoidance of relevant type 1 (IgE …

What is chronic spontaneous urticaria? Chronic spontaneous urticaria (also called chronic idiopathic urticaria) is defined as hives or weals that last for at least 6 weeks, with or without angioedema. Urticaria is often extremely itchy, interfering with sleep, daily activities, social interactions, school, and work life.

2019年4月4日 · Urticaria is characterised by individual weals resolving or changing within 24 hours. The child should be thoroughly examined to detect possible causes. If a food or drug allergy is suspected, a skin prick test or immunoglobulin E (IgE) tests may occasionally be arranged to investigate further.

Angioedema type. Clinical features. Acute allergic angioedema. Almost always occurs with urticaria. Angioedema and urticaria both usually occur within 1-2 hours of exposure to an allergen (exception is ACE inhibitor-induced angioedema that usually occurs within the first week of treatment but can occur weeks to months later)

Chronic urticaria occurs in about 0.1% of the population (Greaves, 2000). Patients previously classified as having chronic idiopathic or "ordinary" urticaria are now divided into two groups: 40% ...
