Effect of Various Genetic Polymorphisms on the Incidence and Outcome of Severe Sepsis

Abstract

Several genetic polymorphisms have been identified in patients with sepsis and severe sepsis, such as the tumor necrosis factor-α (TNF-α) and TNF-β genes, the interleukin-1 (IL-1) family, the IL-6, the IL-10, the CD-14, the Toll-like receptors, plasminogen activator inhibitor type 1, and the factor V 1691G-A mutations. In this study, the relationship between the TNF-α 308G/A, the IL-6-174 G/C, the PAI-1, the FVL, the EPCR, and the Cathepsin G (Ars 125 Ser) polymorphisms and the development and outcome of sepsis in pediatric patients was studied. TNF-α 308 G/A, PAI-1 4G/4G, and EPCR mutations influence the risk of severe sepsis in children. IL-6 174 G/C, FVL, and Cathepsin G (Ars 125 Ser) did not influence the incidence and mortality of severe sepsis.
