عنوان انگلیسی Interleukin-2 and Interferon-Gamma Single Nucleotide Polymorphisms in Iranian Patients with Chronic Heart Failure
چکیده انگلیسی مقاله Background: Inflammatory cytokines have been known to be associated with Chronic Heart Failure (CHF). Given the importance of cytokines in the context of the failing heart, the prevalence of Interleukin-2 (IL-2) and Interferon-gamma (IFN-γ) polymorphisms was studied in patients with CHF due to ischemic heart disease in a case-control study. Methods: Fifty-six Iranian patients with CHF were enrolled in this study as the case group and compared with 139 healthy subjects, using polymerase chain reaction with sequence-specific primers method, so as to determine the frequency of alleles, genotypes and haplotypes of IFN-γ (+874 A/T) and IL-2 (-330 G/T, +166 G/T) SNPs.  Results: The GG genotype at IL-2 -330 in patients with CHF was significantly overrepresented in comparison with the control group (p=0.013). Such a positive genotypic association was also observed for IL-2 +166/TT (p=0.022). Meanwhile, the GT genotype frequency at IL-2 -330/GT in the patient group was significantly lower than the one in healthy controls (p=0.049). No significant association was detected between the IFN-γ gene polymorphisms and individuals' susceptibility to CHF. Conclusion: Certain genotypes in IL-2 gene were overrepresented in patients with CHF, which could render individuals more vulnerable to this disease.
