Cryoglobulins are proteins that become insoluble at less than -4°C. Cryoglobulinaemia can be associated with various diseases: Type I is most commonly encountered in patients with a plasma cell dyscrasia such as multiple myeloma or Waldenström’s macroglobulinaemia. Types II and III are strongly associated with infection by hepatitis C and some connective tissue autoimmune diseases.
Presentation of: arthralgia and joint disease, acrocyanosis, purpura, paraesthesia and peripheral neuropathy or Raynaud’s phenomenon (paroxysmal vasospastic and subsequent vasodilatory sequelae affecting peripheral arterioles usually in the hands and feet; commonly seen in response to cold exposure).
