Immunologic alterations associated with high blood transfusion volume after multiple injury: effects on plasmatic cytokine and cytokine receptor concentrations.
The initial transfusion therapy after trauma has been identified as an independent risk factor for the incidence of multiple organ failure (MOF). Late occurrence of MOF in severely injured patients may be a clinical consequence of disturbed mediator homeostasis. For this reason, levels of interleukin (IL)-6, IL-10, and soluble tumor necrosis factor receptors (sTNFR) p55 and p75 were analyzed in the plasma of patients with comparable injury severity but with a different supply of packed red blood cells (PRBC). Thirty-eight multiple trauma patients with an injury severity score range of 25-54 points were separated into two groups according to their PRBC supply within the first 24 h after trauma. Patients who received at least 15 units of PRBC were analyzed in group 2 (n = 11); the remaining patients (n = 27) were assigned to group 1. The incidence of MOF was higher (P < 0.05) in group 2 patients. Correspondingly, levels of all assayed mediators were found significantly elevated at several time points in this patient group. We conclude that increases in mediator concentrations may be causally related to the extent of blood transfusion therapy itself or to the conditions for which it was needed.
