Which are the symptoms?
Deposits in small blood vessels cause an inflammatory reaction, which often manifests itself in the appearance of small painful red spots on the lower extremities (palpable purpura).
Other symptoms occur in the kidneys (glomerulonephritis) or in the peripheral nervous system (polyneuropathy).
How is it diagnosed?
How is it treated?
The treatment of secondary forms is based on the treatment of the primary disease (for instance, interferon in forms associated with viral hepatitis C).
In some cases, steroid or immunosuppressive therapy is required.
Sometimes it may be necessary to quickly reduce the concentration of cryoglobulins in the blood using plasmapheresis.
