Cold Urticaria

11 min read

Cold urticaria is a condition in which a person experiences hives or other skin reactions when exposed to cold temperatures. It is an allergic reaction to cold temperatures, and can range from mild to severe. It is also known as cold hives, cold allergy, or cold contact urticaria.

Causes of Cold Urticaria

Cold urticaria is caused by an allergic reaction to cold temperatures. It can be triggered by exposure to cold air, water, or objects. It can also be caused by certain medications, such as ACE inhibitors, or by an underlying medical condition, such as an autoimmune disorder.

Diagnosis of Cold Urticaria

Cold urticaria is usually diagnosed by a physical examination and a review of the patient's medical history. A doctor may also order a skin test or a blood test to confirm the diagnosis. In some cases, a doctor may also order an imaging test, such as an MRI or CT scan, to look for any underlying medical conditions.

Complications of Cold Urticaria

Cold urticaria can cause a range of complications, including anaphylaxis, a severe allergic reaction that can be life-threatening. Other complications include difficulty breathing, swelling of the throat, and shock. In some cases, cold urticaria can also lead to secondary infections.

Prevention of Cold Urticaria

The best way to prevent cold urticaria is to avoid exposure to cold temperatures. If you have cold urticaria, it is important to wear warm clothing and to avoid activities that involve cold temperatures. It is also important to avoid certain medications that can trigger an allergic reaction.

Symptoms

Common Symptoms of Cold Urticaria

The most common symptom of cold urticaria is the development of hives or welts on the skin when exposed to cold temperatures. These hives can range in size from small bumps to large welts. They may be itchy and can be accompanied by swelling, redness, and warmth. In some cases, the hives may be accompanied by a burning sensation.

In more severe cases, cold urticaria can cause anaphylaxis, a life-threatening allergic reaction. Symptoms of anaphylaxis include difficulty breathing, swelling of the throat and tongue, dizziness, and a drop in blood pressure. If you experience any of these symptoms, seek medical attention immediately.

Diagnosing Cold Urticaria

If you experience any of the symptoms of cold urticaria, it is important to see a doctor for a diagnosis. Your doctor will likely perform a physical exam and ask questions about your symptoms. They may also order tests, such as a skin prick test or a blood test, to confirm the diagnosis.

Treating Cold Urticaria

Treatment for cold urticaria depends on the severity of the symptoms. Mild cases may be treated with antihistamines, which can help reduce itching and swelling. For more severe cases, your doctor may prescribe corticosteroids or immunosuppressants. In some cases, your doctor may recommend avoiding cold temperatures or wearing protective clothing when exposed to cold temperatures.

Preventing Cold Urticaria

The best way to prevent cold urticaria is to avoid exposure to cold temperatures. If you must be exposed to cold temperatures, wear protective clothing, such as a hat, gloves, and a scarf. You should also avoid activities that involve cold water, such as swimming or skiing. If you experience any symptoms of cold urticaria, seek medical attention immediately.

Take the Cold Urticaria Assessment

Causes

Genetics

Cold urticaria can be inherited, meaning it is passed down from parent to child. It is estimated that up to 10% of people with cold urticaria have a family history of the condition. If a parent has cold urticaria, their children have a higher risk of developing it as well.

Medications

Certain medications can cause cold urticaria as a side effect. These medications include beta-blockers, ACE inhibitors, and angiotensin receptor blockers. If you are taking any of these medications and develop hives when exposed to cold temperatures, it is important to talk to your doctor about the possibility of cold urticaria.

Underlying Medical Conditions

Cold urticaria can also be caused by underlying medical conditions, such as autoimmune disorders, infections, and cancer. If you have an underlying medical condition and develop hives when exposed to cold temperatures, it is important to talk to your doctor about the possibility of cold urticaria.

Getting a Diagnosis

Physical Examination

During a physical examination, a doctor will look for signs of hives or welts on the skin. They may also ask questions about the patient's medical history, such as whether they have had any recent exposure to cold temperatures or if they have any known allergies. The doctor may also take a sample of the patient's skin to examine under a microscope.

Additional Tests

In some cases, additional tests may be necessary to confirm the diagnosis of cold urticaria. These tests may include a skin prick test, a blood test, or a challenge test. During a skin prick test, a small amount of a cold substance is placed on the skin to see if it causes a reaction. A blood test can measure the levels of certain antibodies in the blood that may indicate an allergic reaction. A challenge test involves exposing the patient to cold temperatures to see if it causes a reaction.

Conclusion

Diagnosis of cold urticaria typically involves a physical examination and a review of the patient's medical history. In some cases, additional tests may be necessary to confirm the diagnosis. It is important to seek medical attention if you experience any signs or symptoms of cold urticaria.

Treatment

Antihistamines

Antihistamines are the most common treatment for cold urticaria. They work by blocking the release of histamine, a chemical that causes the skin to become itchy and inflamed. Antihistamines can be taken orally or applied topically to the affected area. Common antihistamines include diphenhydramine (Benadryl), cetirizine (Zyrtec), and loratadine (Claritin).

Corticosteroids

Corticosteroids are a type of medication that can be used to reduce inflammation and itching associated with cold urticaria. They can be taken orally or applied topically to the affected area. Common corticosteroids include prednisone, hydrocortisone, and triamcinolone.

Avoidance of Cold Temperatures

Avoiding cold temperatures is the best way to prevent an outbreak of cold urticaria. This means wearing warm clothing in cold weather, avoiding swimming in cold water, and avoiding contact with cold objects. It is also important to keep the affected area warm and dry.

Phototherapy

Phototherapy is a type of treatment that uses ultraviolet light to reduce inflammation and itching associated with cold urticaria. It is usually done in a doctor's office or clinic and can be used in combination with other treatments. Phototherapy is generally safe and effective, but it can cause skin irritation and sunburn.

Immunotherapy

Immunotherapy is a type of treatment that involves exposing the body to small amounts of the allergen that causes cold urticaria. This helps the body build up a tolerance to the allergen and can reduce the severity of symptoms. Immunotherapy is usually done in a doctor's office or clinic and can be used in combination with other treatments.

Drugs & Medications
