Essential mixed cryoglobulinemia (EMC)

is a rare autoimmune disorder that affects the blood and various other body systems. Patients with EMC have a mixture of various types of antibodies (cryoglobulins) in the blood. Major symptoms may include unusual response to cold, skin abnormalities, weakness and blood problems. There may also be joint pain, inflamed blood vessels, and kidney problems

EMC is one of three conditions associated with Cryoglobulinemia. Cryoglobulinemia is the presence of abnormal proteins in the blood. These abnormal proteins become thick or gel‐like in cold temperatures. Cryoglobulins differ from normal immunoglobulins (antibodies formed by cells of the immune system) because they precipitate at cold conditions but dissolve again when warmed It is not known how or why these cryoglobulins are formed.

Essential mixed cryoglobulinemia is not usually apparent until middle age and affects females more often than males.
