Wn since of our smaller sample size. Further, there’s also a opportunity that these associations might be impacted by the SNPs of nearby genes with which the IREB2 SNPs are in LD. Our study has few Epigenetics limitations. Firstly, only male subjects were included in the study. This was as a consequence of lack of impacted female subjects out there below smoking category. Exposure to biomass fuel smoke could be the predominant danger issue for COPD in females in India. Therefore only smokers were selected using the assumption that the mechanism by which tobacco smoke, which can be a carrier of many Group I and Group II carcinogens, initiates COPD might be distinctive from that of biomass fuel smoke. Second limitation of our study is definitely the sample size. 1 issue that considerably contributed to this was the strict adherence to bidi smokers. Cigarette is costly than bidi. As the majority of the interviewed subjects have been daily wage labors, the decision of smoking medium depended very on the person’s day to day variable monetary status. There had been subjects who smoked both bidi and cigarette. Such subjects have been excluded to avoid misinterpretation of pack years. Lastly, our patient population is just not uniformly distributed across distinctive GOLD stages of COPD. COPD was unknown to all our subjects until diagnosis or our stop by. Patients consulted doctor only when they had severe respiratory challenges due to illness progression. As a result, at the time of initial diagnosis, a lot of the sufferers were either in GOLD stage III or GOLD stage IV. Conclusion Our study managed to reinforce the theories of oxidantantioxidant imbalance, protease-antiprotease imbalance and inflammation upon which the etiology of COPD has been constructed. Although a lot of the associations found within this study happen to be reported elsewhere, the associations identified with IREB2 need to be investigated with bigger sample sizes.

Further, there’s also a opportunity that these associations may be affected by the SNPs of nearby genes with which the IREB2 SNPs are in LD. Our study has couple of limitations. Firstly, only male subjects have been incorporated inside the study. This was because of lack of impacted female subjects offered beneath smoking category. Exposure to biomass fuel smoke is definitely the predominant risk factor for COPD in females in India. Thus only smokers have been chosen with all the assumption that the mechanism by which tobacco smoke, which can be a carrier of several Group I and Group II carcinogens, initiates COPD may very well be diverse from that of biomass fuel smoke.
