How long does it take to get a cryoglobulin test result?
Learning the type of cryoglobulins can sometimes help determine its cause. It takes almost a week after the test is ordered to get the result.
How to treat rash from cryoglobulins?
Another form of treatment decreases the amount of cryoglobulins in the blood. This procedure, called plasmapheresis, removes cryoglobulins from the plasma (the liquid in the blood). This helps prevent cryoglobulins from clogging the arteries, which blocks blood flow and could lead to the rash and organ damage.
What is the best treatment for hepatitis C?
If another medical condition has been found, such as hepatitis C, anti-viral therapy may be recommended, often with referral to a hepatologist (liver specialist).
Is cryoglobulinemia always necessary?
Treatment of cryoglobulinemia is not always necessary and depends on the organs affected, degree of damage, and presence of other medical conditions. It is very important not only to treat the cryoglobulinemia but also to address any other associated disorders.
Can a cryoglobulinemia be idiopathic?
Cryoglobulinemia can be present alone ("idiopathic") or can be associated with other diseases such as: Infection, particularly hepatitis C infection. Blood cell abnormalities such as lymphoma and multiple myeloma. Connective tissue disease such as lupus.
How to treat cryoglobulinemia?
Treatment depends on the type of cryoglobulin, underlying disease, and severity of symptoms. Cryoglobulinemia with severe hyperviscosity syndrome requires plasmapheresis and chemotherapy of the underlying malignancy. Some patients with cryoglobulinemia suffer from mild, recurrent crops of lower extremity purpura that require no specific therapy. More extensive vasculitis associated with autoimmune diseases or essential cryoglobulinemia may respond to prednisone, cyclophosphamide, or both. The most effective treatment for cryoglobulinemia associated with hepatitis C has not yet been determined. Brief use of prednisone followed by 6 months of interferon alfa has produced clinical and liver function test improvement, but relapse of liver disease and vasculitis often occurs when interferon alfa is stopped.
Who wrote the book Cryoglobulinemia?
In medical terms, by David Hellmann, M.D. A discussion of Cryoglobulinemia written in medical terms by David Hellmann, M.D. (F.A.C.P.), Co-Director of the Johns Hopkins Vasculitis Center, for the Rheumatology Section of the Medical Knowledge Self-Assessment Program published and copyrighted by the American College of Physicians (Edition 11, 1998).
What is the name of the disease that causes antibodies to precipitate under cold conditions?
Cryoglobulinemia. The name literally means “cold antibody in the blood”, which refers to the chemical properties of the antibodies that cause this disease: cryoglobulins are antibodies that precipitate under cold conditions. Drug use is a prime risk factor for cryoglobulinemia because more than 90% of cases of cryoglobulinemic vasculitis are ...
Does cryoglobulinemia remit hepatitis C?
It is now evident that most patients diagnosed with type II or type III mixed essential cryoglobulinemia have the disease as an immune response to chronic hepatitis C infection. The role of hepatitis C virus is suggested by finding that the cryoglobulins in these patients are enriched with anti–hepatitis C antibody and hepatitis C RNA. Moreover, antviral therapy can remit the disease in some patients.
What is the cause of cryoglobulinemia?
Cryoglobulinemia is a disease caused by an abundance of a protein called cryoglobulin in the blood. Cryoglobulins are proteins found in the blood stream that clump together in colder temperatures. These clusters cause blood plasma to become very thick, which can block normal blood flow to tissue and organs. Cryoglobulinemia is most common in adults ...
How many types of cryoglobulinemia are there?
There are four main types of cryoglobulinemia:
What causes clumps of abnormal proteins in the blood stream that can block blood flow?
Cryoglobulinemia causes clumps of abnormal proteins in the blood stream that can block blood flow. The blockages can, in turn, cause tissue, joint, nerve, and organ damage. The causes of cryoglobulinemia vary from person to person. Some of the most common causes include: having an abundance of cryoglobulin in the blood. certain blood cell cancers.
What is the purpose of determining the type of cryoglobulins present?
Determining the type of cryoglobulins present will help a doctor determine how best to treat the disease. The type may also help the doctor identify what underlying condition or disease is causing the cryoglobulinemia.
What is the treatment for secondary cryoglobulinemia?
In cases of secondary cryoglobulinemia, treatment involves correcting the underlying condition. When the underlying cause is treated, the symptoms of cryoglobulinemia should improve as well.
Is essential cryoglobulinemia a disease?
Essential cryoglobulinemia has no association with a disease or underlying condition. The presence of type 2 and 3 cryoglobulinemia and their association with hepatitis C lead some researchers to believe there may not be such thing as essential cryoglobulinemia.
Can cryoglobulinemia flare in the summer?
Some people experience continuous symptoms while others go through periods of flares. As cold temperatures play a role in cryoglobulinemia, people may experience flares during colder months and fewer symptoms in the summer.
What is the treatment for cryoglobulinemia?
Cryoglobulinemia is commonly treated with corticosteroids such as prednisone, and medications that suppress the immune system. Antiviral drugs are prescribed when HCV is present. Left untreated, the disease can cause permanent tissue and organ damage, so it is important to seek prompt medical care when symptoms appear.
How to diagnose cryoglobulinemia?
In diagnosing cryoglobulinemia, your doctor will consider a number of factors, including a detailed medical history; physical examination; laboratory tests; specialized imaging studies; and, when indicated, a biopsy of an affected tissue or organ. A specific blood test to detect the presence and type of cryoglobulins in the blood will likely be ordered. These results can help determine how best to treat the disease and identify the underlying disease or cause of the condition. All patients with cryoglobulinemia should be tested for HCV.
What is the name of the disease that causes blood vessels to clump together?
Cryoglobulinemia is a form of vasculitis—a family of rare disorders characterized by inflammation of the blood vessels, which can restrict blood flow and damage vital organs and tissues. In cryoglobulinemia , abnormal blood proteins called cryoglobulins clump together at cold temperatures, restricting blood flow and causing damage to skin, muscles, nerves, and organs—especially the kidneys. More rarely, it can affect the heart, brain, and gastrointestinal tract. Cryoglobulinemia almost always occurs in people who have hepatitis C virus (HCV).
What kind of doctor treats cryoglobulinemia?
In addition to a primary care provider, you may need to see the following specialists: rheumatologist (joints, muscles, immune system); dermatologist (skin); hematologist (blood disorders); nephrologist (kidney disease); hepatologist (liver); cardiologist (heart); neurologist (brain/nervous system); or others as needed.
What tests are used to diagnose cryoglobulinemia?
In diagnosing cryoglobulinemia, your doctor will consider a number of factors, including a detailed medical history; physical examination; laboratory tests; specialized imaging studies; and, when indicated, a biopsy of an affected tissue or organ.
Does cryoglobulinemia affect the heart?
More rarely, it can affect the heart, brain, and gastrointestinal tract. Cryoglobulinemia almost always occurs in people who have hepatitis C virus (HCV). People with cryoglobulinemia may or may not have symptoms.
Can cryoglobulinemia be detected in blood?
The symptoms of cryoglobulinemia vary depending on the organ systems affected. Some people may have no signs except for elevated cryoglobulin levels detected in a blood test. However, when symptoms are present, they typically include the following:
What is cryoglobulinemia?
Introduction. Cryoglobulinemia is a clinical disorder characterized by the presence of cryoglobulins in the serum. Cryoglobulins are immunoglobulins that precipitate in vitro at temperatures below normal body temperature (<37°C) and redissolve upon rewarming.
What is the leading cause of death in HCV-associated cryoglobulinemia?
In comparison, the leading causes of death in HCV-associated cryoglobulinemia are infections (35%), end-stage liver disease (30%), and end-organ damage resulting from vasculitis (17%). 41.
What is the mechanism of cryoglobulin pathogenicity?
The mechanism of cryoglobulin pathogenicity is best described for HCV-associated cryoglobulinemia. 11 HCV drives a clonal B-cell expansion, which secretes a monoclonal IgM that binds to polyclonal IgG molecules, which defines a RF. The IgM interacts with anti-HCV IgG to form immune complexes. These immune complexes bind via a C1q to C1q receptors receptor on endothelial cells, which promotes inflammatory cell recruitment and produces vasculitis. In contrast, the underlying pathogenesis of cryoglobulins in type I is small blood vessel occlusion with minimal inflammatory response ( Figure 1 ).
What is the process of cryoprecipitation?
In type I, the monoclonal component undergoes crystallization and aggregation , which is dependent on temperature and concentration. 9 Although the definition of cryoglobulins is precipitation at cold temperatures, this process can occur at room temperature at high cryoglobulin concentrations. 2 This probably explains why distal extremities (lower temperatures) and kidneys (increase in concentration as a result of ultrafiltration) are major sites of pathology. In type II/III cryoglobulinemia, cryoprecipitation takes place in the setting of immune complex formation between polyclonal IgG and IgM with RF activity and complement fixation. Cryoprecipitation cannot be induced by the IgM or IgG components separately and requires specific antigen-avidity IgG molecules. 10 This underscores the unique properties of cryoglobulins and explains the high incidence of HCV as a cause.
What is the cause of mixed cryoglobulinemia?
Overall, cryoglobulins in mixed cryoglobulinemia result from a B-cell lymphoproliferative process in the setting of persistent immune activation triggered by chronic infection, autoimmune disease, or an unknown cause.
What type of vascular occlusion is demonstrating glomerular intracapillary thrombi?
Schematic illustration of vascular occlusion in type I cryoglobulinemia, demonstrating glomerular intracapillary thrombi.
Is rituximab effective for HCV?
Rituximab was shown to be effective in HCV-associated cryoglobulinemia. In a prospective cohort study, the addition of rituximab to pegylated interferon-ribavirin resulted in a shorter time to response and better renal response and cryoglobulin clearance, although the rate and depth of clinical response and the relapse rate were similar between study arms. Two randomized trials evaluated rituximab in mixed cryoglobulinemia, mostly in the setting of HCV. In the first trial, 2 doses of rituximab 1 g/m 2 days 1 and 14 were compared with other IST therapies in patients for whom anti-HCV therapy failed or who could not tolerate it. At 12 months, a treatment-free status was more likely in the rituximab arm. Organ improvement was better with rituximab, predominantly for skin and renal involvement. 33 The second trial (with a similar design) evaluated rituximab (375 mg/m 2, 4 weekly doses) compared with other IST therapies. At 6 months, the remission rate was 83% in the rituximab arm compared with 8% in the control arm. 55
