Adrenergic urticaria

Adrenergic Urticaria

Adrenergic urticaria (/ædˌrɛnərˈdʒɪk ɜːrtɪˈkɛəriə/) is a rare form of urticaria, a skin condition characterized by the rapid onset of itchy hives. The term "adrenergic" refers to the involvement of the adrenaline (also known as epinephrine) system in this condition.

Etymology

The term "adrenergic urticaria" is derived from two words: "adrenergic", which refers to the adrenaline system, and "urticaria", which is a medical term for hives. The term "urticaria" is derived from the Latin word "urtica", meaning "nettle", a plant known to cause skin irritation and hives when touched.

Symptoms

The primary symptom of adrenergic urticaria is the sudden onset of itchy hives, usually in response to stress or excitement. Other symptoms may include flushing, headache, and a rapid heartbeat. In severe cases, patients may experience anaphylaxis, a severe allergic reaction that can be life-threatening.

Diagnosis

Diagnosis of adrenergic urticaria is typically based on the patient's symptoms and medical history. A dermatologist may perform a physical examination and order tests to rule out other conditions. In some cases, a skin biopsy may be necessary.

Treatment

Treatment for adrenergic urticaria typically involves avoiding triggers, such as stress or excitement, and managing symptoms with medications. These may include antihistamines, corticosteroids, or beta-blockers. In severe cases, an epinephrine autoinjector may be prescribed.
