RESUMO
Here, we conducted a case-control study to investigate the association between IL-10 gene polymorphisms and development of CAD in a Chinese population. A total of 220 patients with CAD and 236 control subjects who visited the Zhengzhou People's Hospital between May 2012 and June 2014 were selected for this study. The IL-10-1082A/G and -592A/C polymorphisms were genotyped by polymerase chain reaction coupled with restriction fragment length polymorphism. The chi-squared test revealed a significant difference in the distributions of the IL-10-1082A/G genotypes (χ2 = 6.32, P = 0.04). This data was then statistically analyzed by logistic regression analysis; we observed revealed that the CC genotype of IL-10-1082A/G had a higher risk of CAD in comparison to the AA genotype (OR = 2.09, 95%CI = 1.11-3.97). Moreover, the C allele of IL-10-1082A/G had a 1.39 fold risk of CAD when compared with (OR = 1.39, 95%CI = 1.06-1.82). We did not observe any significant correlations between the IL-10-592A/C genetic variation and susceptibility to CAD. In conclusion, our study suggests that the IL-10-1082A/G genetic variation could influence the development of CAD in a Chinese population.

To investigate the role of IL-6 polymorphism (-174G/C and -572C/G) in the development of coronary artery disease (CAD), CAD patients (224) and control subjects (260) were recruited between January 2012 and December 2014. Genotyping at IL-6 -174G/C and -572C/G was conducted via polymerase chain reaction coupled to restriction fragment length polymorphism. Results indicated that several disease risk factors were significantly higher in CAD patients as compared to the control subjects. These factors include hypertension (χ2 = 20.03, P < 0.001), diabetes mellitus (χ(2) = 33.53, P < 0.001), tobacco smoking (χ(2) = 28.17, P < 0.001), body mass indexes (t = 11.39, P < 0.001), total cholesterol (t = 8.25, P < 0.001), low-density lipoprotein cholesterol (t = 7.24, P < 0.001), high-density lipoprotein cholesterol (t = 3.52, P < 0.001), and triglyceride (t = 6.09, P < 0.001). By unconditional logistic regression analysis, we observed that the CC genotype at IL-6 -174G/C was had a 2.32 (95%CI = 1.33-4.06) fold risk of developing CAD compared to the GG genotype. Moreover, IL-6 -174G/C polymorphism was positively associated with the risk of developing CAD in both dominant (OR = 1.63, 95%CI = 1.12-2.38; P = 0.01) and recessive models (OR = 2.18, 95%CI = 1.26-3.77; P = 0.001). However, no statistically significant association was observed between IL-6 -572C/G polymorphism and risk of CAD. In conclusion, IL-6 -174G/C polymorphisms are associated with the pathogenesis of CAD.

A case-control study was conducted to investigate the association between genetic variants of IL-17A rs2275913 and IL-17F rs763780 and the development of coronary artery disease (CAD) in a Chinese population. A total of 306 individuals with CAD and 306 unaffected individuals were enrolled from the Zhengzhou People's Hospital between May 2012 and May 2014. The IL-17A rs2275913 and IL-17F rs763780 genes were genotyped by polymerase chain reaction combined with a restriction fragment length polymorphism (PCR-RFLP). Logistic regression analysis revealed that individuals with the AA genotype of rs2275913 were associated with increased risk of CAD, compared to those with the GG genotype in a codominant model [adjusted odds ratio (OR) = 1.96; 95% confidence interval (CI) = 1.10-3.53]. On the other hand, the AA genotype of rs2275913 was correlated with moderately increased risk of CAD compared to the GG + GA genotype (adjusted OR = 1.76; 95%CI = 1.02-3.07) in a recessive model. However, no significant differences were observed between polymorphisms at the IL-17F rs763780 locus and CAD risk, in codominant, dominant, and recessive models. In conclusion, the results of our study suggested that the IL-17A rs2275913 polymorphism may affect the development of CAD; however, no significant association was observed between the IL-17F rs763780 polymorphism and risk of CAD.
