Cryoglobulinemia is the presence of abnormal proteins that are occasionally found in the blood of people with some forms of autoimmune diseases, multiple myeloma, leukemia, and certain forms of pneumonia. The proteins cause the blood to gel at low temperatures causing tissue necrosis.
Causes: Type 1 cryoglobulinemia is often associated with lymphoma. Type 2 cryoglobulinemia is often associated with hepatitis C infection. Drug usage is a prime risk factor for patients with cryoglobulinemia. Hepatitis C is acquired by injection drug use (needle–sharing), tainted blood products, and (probably rarely), sexual transmission.
Symptoms may include a rash on the lower limbs, arthritis, nerve damage and tissue necrosis of affected areas.
Treating the hepatitis may be an effective therapy for this type of vasculitis.

Rituximab to Treat Hepatitis C-Associated Cryoglobulinemic Vasculitis
Characterization of Clonal B Cell Populations in HCV Infection Edgar Charles, MD, Principal Investigator Rockefeller University Research on Cryoglobulinemia from Entrez Pubmed: The US National Library of Medicine has a search service that allows anyone with internet access to look for medical articles free of charge. PubMed makes it easy to look up diseases, medicines, research authors or any combination of the above. Here is a partial listing of some of the research. It is important to note that much research results in preliminary findings that should not be confused with established fact.
