Monoclonal cryo-antifibrinogenemia.
We report on a 54-year-old female patient with arthritis and a severe cold-induced leukocytoclastic vasculitis of the skin caused by a rare form of cryofibrinogenemia ("type II" cryofibrinogen). Affinity chromatography of cryoprecipitates from the patient's plasma revealed reversible cryoprecipitability of complexes composed of fibrinogen and a monoclonal antifibrinogen antibody (IgG3 kappa). Conventional serum and plasma electrophoresis did not detect the paraprotein. Control of symptoms was achieved by long-term plasmapheresis.
