Background: Sepsis is now the leading cause of death in the non-cardiovascular intensive care unit (ICU). Recent research suggests that sepsis is likely to be due to an interaction between genetic and environmental factors. Genetic mutations of toll-like receptor 4 (TLR4) and cluster of differentiation 14 (CD14) genes are involved in the immune and (or) inflammatory response. These may contribute to the susceptibility to sepsis in patients. This study was designed to evaluate whether the and cluster gene polymorphisms are associated with susceptibility to sepsis. Methods: The single nucleotide polymorphisms (SNPs) of (rs10759932, rs11536889, rs7873784, rs12377632, rs1927907, rs1153879) and (rs2569190 and rs2563298) in patients with sepsis and control subjects in the Guangxi Province were analyzed by using the polymerase chain reaction-single base extension (PCR-SBE) and DNA sequencing methods. Results: The rs11536889 polymorphism in and rs2563298 polymorphism in were significantly associated with the risk of sepsis when compared to the control group. The frequencies of rs11536889 and rs2563298 polymorphisms in the group with sepsis were higher than that in the control group (OR = 1.430, 9, 1.032-1.981, 0.05; R = 2.454, 1.458-4.130, <0.05, respectively). Followed up haplotype analysis suggested that there were two haplotypes in which increased risk factors for sepsis were indicated. Conclusions: The rs11536889 polymorphism in and rs2563298 polymorphism in CD14, and two haplotypes were associated with increased susceptibility to sepsis.
