Wn since of our compact 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 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. 125-65-5 Exposure to biomass fuel smoke could be the predominant threat 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.

Firstly, only male subjects were integrated within the study. This was as a result of lack of affected female subjects readily available below smoking category. Exposure to biomass fuel smoke is definitely the predominant threat element for COPD in females in India. Consequently only smokers have been selected using the assumption that the mechanism by which tobacco smoke, that is a carrier of various Group I and Group II carcinogens, initiates COPD could possibly be distinct from that of biomass fuel smoke. Second limitation of our study will be the sample size. One issue that considerably contributed to this was the strict adherence to bidi smokers. Cigarette is costly than bidi.

There had been subjects who smoked both bidi and cigarette. Such subjects have been excluded to prevent misinterpretation of pack years. Lastly, our patient population is not uniformly distributed across unique GOLD stages of COPD. COPD was unknown to all our subjects till diagnosis or our visit. Patients consulted physician only once they had serious respiratory complications due to disease progression. For that reason, at the time of initial diagnosis, many of the patients have been 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. Whilst the majority of the associations found within this study have already been reported elsewhere, the associations located with IREB2 must be investigated with bigger sample sizes.
