What is Cryoglobulinemia?
Written by Medicover Team and Medically Reviewed by DR Vidya Sagar Dusi , Oncologists
Cryoglobulinemia is a rare condition where unusual proteins called cryoglobulins are found in the blood. These proteins thicken or turn into a gel when it's cold. This can block blood vessels and cause swelling and damage to tissues. It can happen by itself or because of other illnesses like hepatitis C, autoimmune diseases, or some cancers.
While they remain dissolved at normal temperatures, cooler conditions can cause these proteins to form clumps that block blood flow.
This can lead to inflammation of the blood vessels (vasculitis) and may harm organs such as the skin, kidneys, or nerves.
What are the Causes of Cryoglobulinemia?
Cryoglobulinemia can be caused by various underlying health conditions. Identifying the cause helps doctors choose the most effective treatment plan and manage symptoms more efficiently.
Common causes include
- Chronic infections (especially hepatitis C virus)
- This is the most common cause and can lead to long-term inflammation and immune system changes.
- Autoimmune diseases
- Conditions like lupus or rheumatoid arthritis can trigger the immune system to produce cryoglobulins.
- Certain blood cancers
- Lymphomas or multiple myeloma can lead to abnormal protein production in the blood.
- Unknown causes (essential cryoglobulinemia)
In some cases, no clear cause is found, and the condition occurs without another disease.

Get Second OpinionWhat are the Symptoms of Cryoglobulinemia?
Symptoms often depend on how much the blood vessels are affected and which organs are involved. Some people may not notice symptoms at first, while others may have flare-ups triggered by cold temperatures.
Typical signs and symptoms include
- Fatigue and weakness
- Joint pain and muscle pain
- Skin rashes (purpura)
- Numbness or tingling
- Kidney problems
In some cases, the kidneys may be affected, leading to blood or protein in the urine.
How Is Cryoglobulinemia Diagnosed?
Diagnosis involves blood tests and clinical evaluation. Detecting the presence of cryoglobulins and understanding the underlying cause is key to forming an effective treatment plan.
Tests may include
- Blood tests: These help identify cryoglobulins and check for inflammation, infection, or autoimmune markers.
- Cryocrit test: A specific test to measure the level of cryoglobulins in the blood.
- Hepatitis C testing: Since hepatitis C is a leading cause, testing for this virus is often essential.
- Kidney function tests and urine analysis: These checks are for any damage to the kidneys.
- Tissue biopsy: In some cases, a biopsy of the skin or kidneys may be done to look for blood vessel inflammation.
What are the Treatment options for Cryoglobulinemia
Treatment depends on the underlying cause and the severity of symptoms. The goal is to reduce inflammation, manage symptoms, and treat any related health issues.
- Standard treatment options include: Treating the underlying disease. If hepatitis C or another condition is present, treating it can often improve cryoglobulinemia.
- Corticosteroids and immunosuppressants: These reduce immune system activity and inflammation.
- Antiviral therapy: Used in hepatitis C-related cases to reduce viral load and improve symptoms.
- Plasmapheresis (plasma exchange): This may be used in severe cases to remove cryoglobulins from the blood Pain relievers and lifestyle changes
These help manage day-to-day symptoms and reduce exposure to cold.
Complications of Cryoglobulinemia
If not treated properly, cryoglobulinemia can lead to serious complications involving vital organs.
Potential complications include
- Kidney damage: Can lead to chronic kidney disease or failure in severe cases.
- Nerve damage: May cause long-term numbness or weakness in the limbs.
- Widespread blood vessel inflammation (vasculitis): Can affect organs like the heart, lungs, or brain.
Early treatment and close monitoring can help prevent these complications.
When to See a Doctor
You should see a doctor if you notice signs like ongoing fatigue, joint pain, unusual skin rashes (especially red or purple spots), numbness in your hands or feet, or swelling. If you have a condition like hepatitis C or an autoimmune disease and develop these symptoms, it's especially important to get checked.
Early diagnosis and treatment can help prevent serious problems and protect your organs.
