TREM-1 acts to amplify infl ammation and serves as a critical mediator of infl ammatory response in the context of sepsis. To date, the predisposition of TREM-1 gene polymorphisms to septic shock has not been reported. This study was designed to investigate whether TREM-1 genomic variations are associated with the development of septic shock.METHODS: We genotyped two TREM-1 single nucleotide polymorphisms(SNPs, rs2234237 and rs2234246) and evaluated the relationships between these SNPs and septic shock on susceptibility and prognosis.RESULTS: TREM-1 rs2234246 A allele in the promoter region was signifi cantly associated with the susceptibility of septic shock in recessive model(AA, OR=3.10, 95%CI 1.15 to 8.32, P=0.02), and in codominant model(AG, OR=0.72, 95%CI 0.43–1.19, P=0.02; AA, OR=2.71, 95%CI 1.00–7.42; P=0.03). However, in three inherited models(dominant model, recessive model, and codominant model), none of the assayed loci was signif icantly associated with the prognosis of septic shock. The nonsurvivor group demonstrated higher plasma IL-6 levels(99.7±34.7 pg/mL vs. 61.2±26.5 pg/mL, P<0.01) than the survivor group. Plasma concentrations of IL-6 among the three genotypes of rs2234246 were AA 99.4±48.9 pg/m L, AG 85.4±43 pg/m L, and GG 65.3±30.7 pg/m L(P<0.01). The plasma concentrations of IL-6 in patients with AA genotypes were signifi cantly higher than those in patients with GG genotypes(P<0.01).CONCLUSION: TREM-1 genetic polymorphisms rs2234246 may be significantly correlated only with susceptibility to septic shock in the Chinese Han population.展开更多
