Alterations of acute phase reaction and cytokine production in patients following severe burn injury

To determine the acute immunologic reaction, mediated by cytokines, interleukines (lLs) and growth factors and the susceptibility to infections and sepsis after severe burn injury a prospective, single unit, longitudinal study of acute phase. reactants and mediators who performed. After approval by the ethics committee of our hospital, we investigated the plasma concentrations of IL-2,-6,-8, -10, and -13, the soluble IL-2 receptor (sIL-2R), and the acute phase proteins procalcitonin (PCT) and C-reactive protein (CRP) at admission and every 3 days in 24 patients over a time course of 28 days after thermal injury and categorized by percent burn: less than or equal to30% (group 1; n = 12) and >30% (group 2;n = 12). Shortly after burn injury we found higher concentrations of IL-2, -6, -10 and PCT in those patients >30% TBSA. During the study period, we found significant higher levels of acute phase proteins, IL-6 and -8 in patients >30% TBSA. The incidence of SIRS and MODS was three times increased in patients >30% TBSA. Our results show different patterns of cytokines and acute phase proteins in patients with different burned surface areas over a long time and continuous monitoring of a more distinct inflammatory response in these patients.
