[Association of cytokines genes (ILL, IL1RN, TNF, LTA, IL6, IL8, IL0) polymorphic markers with chronic obstructive pulmonary disease].
The purpose of this study was to investigate the possible roles of the cytokines genes in the development of chronic obstructive pulmonary disease (COPD). Polymorphisms in the genes encoding IL1B, IL1RN, TNFA, LTA, IL6, IL8 H IL10 were investigated in COPD patients (N = 319) and healthy individuals (N = 403) living in Ufa, the Republic of Bashkortostan. We observed that IL1RN*2/IL1RN*2 genotype of ILRN gene was associated with susceptibility for COPD (9.8% vs. 4.67%; chi(2)= 5.45, df= 1, P = 0.02; OR = 2.21). Analysis of the LTA gene polymorphic locus A252G showed that in patients with COPD, the frequency of the GG genotype was significantly higher than that in the control group (7.84% vs. 3.72%; chi(2) = 5.00, df= 1, P = 0.025). The increase of this genotype was significant in case of stage IV of COPD (11.18% vs. 4.79%; chi(2) = 3.075, df= 1, P = 0.07). Frequency of genotype combination TNFA-308 G/G and LTA252 A/A significantly decreased in COPD group (38.55% vs. 46.93% in control group; chi(2) = 8.82, df= 1, P = 0.0039). The frequency of GG genotype of the IL6 gene was higher in the patients with stage IV of COPD (43.75% vs. 31.54%, chi(2) = 4.14, P = 0.041). Our results indicate that the genotype frequency of the T(-511)C, T3953C of IL1B, G(-308)A of TNFA, G(-1 74)C of IL6, A(-251)C of IL8 and C(-627)A of ILl0 genes polymorphisms was similar in COPD and healthy control groups.
