Cryoglobulins may be present in
macroglobulinemia of Waldenström, myeloma, chronic lymphocytic leukemia, lupus,
chronic active hepatitis, and other viral infections.
Cryoglobulins are proteins which precipitate
from blood at low temperatures. A precipitate from serum which forms overnight
at 4°C and dissolves at 37°C is called a cryoglobulin.
Cryoglobulins may be divided into
three classes. Type I are monoclonal immunoglobulins and are usually associated
with lymphoproliferative disorders. Type II are mixtures of a monoclonal IgM
and polyclonal IgG, and are associated with macroglobulinemia and chronic
active hepatitis. Type III are mixtures of polyclonal IgM and polyclonal IgG.
These are found in a wide variety of disorders.
