Overview
History and Symptoms
- Acute urticaria usually appears few minutes after contact with the allergen and can last from few hours to several weeks. Food allergic reactions could fit in this category. Common causes of reaction include consumption of shellfish, nuts, eggs, fish, acid derivatives, dye, or a combination of these.
- Chronic urticaria refers to hives that persists for at least 6 weeks. There are no differences in physical examination of acute and chronic urticaria. Some of the more severe cases of chronic urticaria have been lasted more than 20 years. A survey indicated that chronic urticaria lasted a year or more in more than 50% of patients and 20 years or more in 20% of them. Of course this does mean that in almost half the patients it clears up within a year and in 80% of them it clears up within 20 years or less.[1]
- Drug-induced urticaria has been known to result in severe cardiorespiratory failure. The anti-diabetic treatments, such as sulphonylurea glimepiride (trade name Amaryl®), in particular, have been documented to cause allergic reactions manifesting as urticaria. Other cases include dextroamphetamine, aspirin, penicillin, clotrimazole, sulfonamides and anticonvulsants.[2]
- Physical urticaria symptoms develop after exposure to the physical agent/pressure.
- Development of hives after exercise, passive increase in body temperature (such as hot bath) and emotional stress suggest cholinergic urticaria.[3]
- In adrenergic urticaria development of wheals occurs after emotional stress and not due to body temperature elevation.[4]
