Cryoglobulinemia type 1

Immune System Diseases

Summary Summary

Simple cryoglobulinemia occurs when the body makes an abnormal immune system protein called a cryoglobulin. At temperatures less than 98.6 degrees Fahrenheit (normal body temperature), cryoglobulins become solid or gel-like and can block blood vessels. This causes a variety of health problems. Many people with cryoglobulins will not experience any symptoms. If symptoms occur, they may include skin ulcers, purple skin spots (purpura), numbness in the fingers and toes (Raynaud's phenomenon), joint pain, and kidney problems. The underlying cause is unknown. Simple cryoglobulinemia is typically associated with immune system cancers, such as multiple myeloma or non-Hodgkin lymphoma. It is diagnosed based on the results of a clinical exam and the presence of cryoglobulins in the blood. Treatment varies based on the severity of symptoms and any underlying conditions.^[1]^[2]^[3]^[4]

Symptoms Symptoms

The following list includes the most common signs and symptoms in people with simple cryoglobulinemia. These features may be different from person to person. Some people may have more symptoms than others and symptoms can range from mild to severe. This list does not include every symptom or feature that has been described in this condition.

Signs and symptoms may include:^[4]

Purple spots and patches on the skin (purpura)
Skin ulcers
Nerve damage (peripheral neuropathy)
Numbness or tingling of the fingers and/or toes (Raynaud's phenomenon)
Joint pain and swelling (arthralgia)
Kidney problems

The severity of the symptoms can be difficult to predict, and may depend on underlying conditions. People who have kidney and nervous system involvement tend to have more severe disease. In rare cases, symptoms of simple cryoglobulinemia can be life-threatening.^[2]^[4]

Cause Cause

The cause of simple cryoglobulinemia is unknown. It occurs mainly in people with cancers of the immune system, such as multiple myeloma and non-Hodgkin's lymphoma.^[4]

In some cases, cryoglobulinemia occurs in someone with no underlying health condition. In these cases, it is known as essential or idiopathic cryoglobulinemia.^[1]

Diagnosis Diagnosis

Simple cryoglobulinemia can be diagnosed based on a clinical history and exam, the symptoms, and testing to look for cryoglobulins in the blood. People found to have cryoglobulinemia are often tested for underlying immune system disorders.^[1]^[2]
