Liver problems. Symptoms usually begin between ages 40 and 60. Although cryoglobulinemic vasculitis is a long-term disease, symptoms tend come and go. The severity of the symptoms can be difficult to predict, and may depend on underlying conditions. People who have organ involvement tend to have more severe disease.
What causes cryoglobulins to become solid?
Cryoglobulinemic vasculitis occurs when the body makes a mix of abnormal immune system proteins called cryoglobulins. 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. When symptoms occur, they may include purplish discolored skin ( purpura ), weakness, joint pain, liver disease, and kidney problems. The underlying cause is unknown. Cryoglobulinemic vasculitis is typically associated with a chronic hepatitis C virus (HCV) infection. 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]

What is a CryoVas?
Cryoglobulinemic vasculitis (CryoVas) is a small-vessel vasculitis involving mainly the skin , the joints, the peripheral nervous system , and the kidneys. Type I CryoVas is single monoclonal immunoglobulins related to an underlying B-cell lymphoproliferative disorder. Type II and III cryoglobulins, often referred to as mixed cryoglobulinemia, consist of polyclonal immunoglobulin (Ig)G with or without monoclonal IgM with rheumatoid factor activity. Hepatitis C virus (HCV) infection represents the main cause of mixed CryoVas. The 10-year survival rates are 63%, 65%, and 87% in HCV-positive mixed CryoVas, HCV-negative mixed CryoVas, and type I CryoVas patients, respectively. In HCV-positive patients, baseline poor prognostic factors include the presence of severe liver fibrosis, and central nervous system, kidney, and heart involvement. Treatment with antivirals is associated with a good prognosis, whereas use of immunosuppressants (including corticosteroids) is associated with a poor outcome. In HCV-negative patients, pulmonary and gastrointestinal involvement, renal insufficiency, and age > 65 years are independently associated with death. Increased risk of lymphoma also should be underlined. Treatment of type I CryoVas is that of the hemopathy; specific treatment also includes plasma exchange, corticosteroids, rituximab, and ilomedine. In HCV-CryoVas with mild-to-moderate disease, an optimal antiviral treatment should be given. For HCV-CryoVas with severe vasculitis (ie, worsening of renal function, mononeuritis multiplex, extensive skin disease, intestinal ischemia…) control of disease with rituximab, with or without plasmapheresis, is required before initiation of antiviral therapy. Other immunosuppressants should be given only in case of refractory forms of CryoVas, frequently associated with underlying B-cell lymphoma.
What is the treatment for type 1 CryoVas?
Treatment of type I CryoVas is that of the hemopathy; specific treatment also includes plasma exchange, corticosteroids, rituximab, and ilomedine. In HCV-CryoVas with mild-to-moderate disease, an optimal antiviral treatment should be given.

What is the term for antibodies that are soluble in the blood but which precipitate out of the blood at lower temperatures?
Cryoglobulinemia means “cold antibody in the blood” and is the presence of abnormal antibodies that are soluble in the blood at body temperature but which precipitate out of the blood at lower temperatures in the laboratory. These antibodies are often present in patients with a wide variety of pre-existing diseases such as hepatitis C virus infection, autoimmune diseases such as rheumatoid arthritis or Sjögren’s Syndrome or cancers such as lymphoma or multiple myeloma. In the very rare cases where an underlying disease is not identified the presence of cryoglobulin antibodies in the blood is called “essential cryoglobulinaemia ”. Often the antibodies do not cause any problems and then no treatment may be needed. In some patients they cause a vasculitis of the small and medium blood vessels called Cryoglobulinaemic Vasculitis. This condition may need treatment.
