Background: One of the principal cigarette smokes (CS) mediated diseases is chronic obstructive pulmonary disease (COPD). Methods: In the current case-control study, the relationship between the polymorphisms of interleukin-10 (IL-10), transforming growth factor-β1 (TGF-β1 ) codon 10, TGF-β1 codon 25, interferon-γ (IFN-γ), and tumor necrosis factor-α (TNF-α) in 213 individuals with COPD and susceptibility to the disease, with 100 healthy age and gender-matched people as a control group, was investigated using PCR-ARMS (polymerase chain reaction-amplification refractory mutation system). Moreover, the combination of the polymorphisms of TGF-β1 codon 10.25 regarding this susceptibility was studied in the same condition. Results: There was a significant difference between polymorphism of TGF-β1 codon 10 (+869 T/C), codon 25 (G+915C), and susceptibility to the disease (OR=0.50; (95 %CI=0.24-1.07, p=0.05), ORCC =5.31; (95% CI: 1.22-23.2); p=0.02), thus polymorphism of IL-10 and TGF-β1 increased the risk of susceptibility to COPD but the polymorphisms of TNF-α (G-308A) and IFN-γ (+847 T/A) did not show any association. Conclusion: All in all, it is recommended that the patients carrying the above-said genotypes should be paid proper attention, especially those who are exposed to chemicals at their workplaces, pollution, and cigarette smoke.
