Abstract
Objective To explore the effect of tumor necrosis faction-α(TNF-α)gene rs1799964 and C-reactive protein(CRP)gene rs2794521 polymorphism and their interaction on the therapeutic effect of dagliaglozin in patients with heart failure.Meth-ods 98 patients with HF who received treatment in Chengdu Wenjiang District People's Hospital from January 2021 to October 2023 were retrospectively selected for the study.According to the different therapeutic effects,the patients were divided into effective group(n=61)and ineffective group(n=37).The laboratory indexes of the effective group and the ineffective group were compared.The polymorphism,genotype and allele distribution of TNF-α gene(rs1799964)and CRP gene(rs2794521)were analyzed.Multiple regression model was used to analyze the risk factors affecting the efficacy of dagaglizin in the treatment of HF.The association between TNF-α gene(rs1799964)and CRP gene(rs2794521)and cardiac function index was analyzed.To analyze the interaction between TNF-α polymorphism(rs1799964)and CRP polymorphism(rs2794521)on the efficacy of daglipzin in the treatment of HF.Results The frequencies of CC genotype,CT genotype and C allele of TNF-α gene(rs1799964)in ineffective group were 24.32%(9/37),54.05%(20/37)and 51.35%(38/74),respectively,which were higher than those in effective group 11.48%(7/61),40.98%(25/61)and 31.97%(39/122),the differences were statistically significant(χ2=7.284,7.256,7213,all P<0.05).The frequencies of CC genotype and C allele of CRP gene(rs2794521)in ineffective group were 24.32%(9/37)and 47.30%(35/74),respectively,which were higher than those in effective group 6.56%(4/61)and 28.69%(35/122),and the differences were statistically significant(χ2=7.578,6.947,all P<0.05).In the dominant mode and in the cumula-tive mode in the association between TNF-α gene(rs1799964)and CRP gene(rs2794521)was statistically significant(all P<0.05).TNF-α gene(rs1799964)CC genotype(β=1.134,95%CI:1.028～1.964),CRP gene(rs2794521)CT genotype(β=1.357,95%CI:1.239～2.154),CC genotype(β=2.017,95%CI:1.674～4.231)were independent risk factors for the efficacy of daglipzin in treating HF(all P<0.05).The association differences between TNF-α gene(rs1799964)and CRP gene(rs2794521)polymorphism and left ventricular end-systolic dimension(LVESd),left ventricular end diastolic dimension(LVEDd),left ventric-ular ejection fractions(LVEF)and stroke volume(SV)in additive and dominant models were statistically significant(all P<0.05).There were multiplicative and additive interactions between TNF-α gene(rs1799964)genotype CC and CRP gene(rs2794521)genotype CC(all P<0.05).Conclusion The TNF-α gene(rs1799964)genotype CC and CRP gene(rs2794521)genotype CC have a multiplicity and additional interaction,and the risk of daglaglizin in treating heart failure is higher when these two factors coexist.关键词
