Hives

Hives: Introduction

Hives are a common condition in which itchy, red lumps and bumps (wheals) form on the skin. Hive are also called uticaria.

Hives are usually caused by a mild allergic reaction, but they can also be caused by a rare but severe allergic reaction called an anaphylactic reaction. Very rarely, hives can be caused by an autoimmune disorder called lupus. For more information on causes, refer to causes of hives.

Hives can appear anywhere on the body and can be round or oval in shape. Hives can also be irregularly shaped lumpy patches that join together to cover large areas of skin. Hives can be red or pink in color. They can also have a pale center with redness on the edges of the hives. The area of the body affected by hives is generally very itchy.

Symptoms that can accompany hives due to an allergic reaction include sneezing, runny nose, itchy, watery eyes, nasal congestion, sinus pressure, and headache. A severe allergic reaction (anaphylactic reaction) can result in swelling of the throat, mouth, and lips, and shortness of breath.

Symptoms that can accompany hives due to lupus include a butterfly shaped rash on the face, fever, seizures, anemia, photophobia, painful, swollen joints, hair loss, lesions in the mouth or nose, and inflammation of the lungs.

Making a diagnosis of hives and their underlying cause includes performing a complete evaluation that includes a medical and allergy history and physical examination.

If it is suspected that hives may be caused by an allergy, diagnostic testing may include skin patch testing. In a skin patch test, small amounts of common allergens are applied methodically to the skin to determine what substances are triggering an allergic response. A blood test called a radioallergosorbent test (RAST) may also be done to help identify the substances that are causing certain allergies. For suspected food allergies, a patient may also be asked to keep a log to record the types of foods that trigger the appearance of hives.

If it is suspected that hives may be caused by lupus, diagnostic testing includes a performing a variety of blood tests in order to detect the presence of autoantibodies, which are found in the body with lupus and other autoimmune diseases.

It is very possible that a diagnosis of hives can be missed or delayed because symptoms can be similar to other conditions. For more information on misdiagnosis, refer to misdiagnosis of hives.

Patient compliance with a good treatment plan can control hives due to allergies to a degree that allows a person to live a normal active life. Treatment may include a combination of lifestyle changes, medications, and other measures. Treatment of hives due to lupus also includes a variety of therapies.
