Plasma fibronectin in myeloproliferative disorders and chronic granulocytic leukaemia. 1983

D R Norfolk, and M Bowen, and B E Roberts, and J A Child

A significant reduction of plasma fibronectin levels was found in polycythaemia vera and myelofibrosis, the lowest levels being found in patients with marked splenomegaly. Plasma fibronectin concentration was normal in essential thrombocythaemia, and only modest reduction was seen in chronic granulocytic leukaemia in either controlled chronic phase or blast cell crisis. In a patient with myelofibrosis, the plasma fibronectin rose from less than 100 mg/l to 177 mg/l after splenectomy. Possible explanations include increased consumption of plasma fibronectin in the expanded mononuclear phagocyte system present in the liver and spleen, reduced hepatic synthesis, and the clearance of circulating immune complexes. Low plasma fibronectin concentrations may increase susceptibility to infection.

D005353 Fibronectins Glycoproteins found on the surfaces of cells, particularly in fibrillar structures. The proteins are lost or reduced when these cells undergo viral or chemical transformation. They are highly susceptible to proteolysis and are substrates for activated blood coagulation factor VIII. The forms present in plasma are called cold-insoluble globulins.
