title: Clinical response to cold insoluble globulin replacement in a patient with sepsis and thermal injury.
abstract: Cold insoluble globulin (fibronectin, alpha 2-surface binding glycoprotein) is a naturally occurring substance necessary for optimal stimulation of the reticuloendothelial system. While this globulin depends on macrophages as the effector cells for its opsonic function, as is true of both antibody and complement, it is neither part of nor dependent on these systems for its opsonic activity. A relatively simple bioassay developed at the Medical College of Georgia substantiated that cold insoluble globulin is severely depleted in sepsis. Cryoprecipitate, properly processed and stored, is an exogenous source of cold insoluble globulin. Infused into septic patients 10 units thawed at 2 degrees C and reconstituted to 250 ml with saline solution can temporarily restore cold insoluble globulin levels and enhance activity of the reticuloendothelial system. Proper current use dictates measurement of cold insoluble globulin levels in the infusate as well as levels in the patient and the clinical response to infusion. Our bioassay and a septic patient's response to infusion of cold insoluble globulin are reported herein.
