Changes in systemic inflammatory and nasal mucociliary response following smoking cessation

This study aimed to evaluate the changesboth in the systemic inflammation and in the mucociliary clearance followingsmoking cessation, and their associations with smoking characteristics.Methods: A total of 30 cases admitted to Konya Training andResearch Hospital, University of Health Sciences, Department of SmokingCessation were recruited, and 27 of them completed the study. Tumor necrosisfactor alpha (TNF-α), interleukin (IL) -4, IL-6, IL-8, IL-10 and saccharintransit time (STT) was measuredat the beginning and 2 months after smokingcessation.Results: We found in this study that STT decreased significantlyin 2 months after cessation (p<0.001). In our study, we found that serumTNF-α (p=0.035) and IL-8 (p=0.002) levels were decreased significantly at 2months after quitting when compared with the basal levels. In our study, serumIL-6 (p=0.132) and IL-10 (p=0.657) levels did not change significantly in the2nd month of quitting, when compared to basal levels.Conclusion: In this study, two months after smoking cessation,nasal mucosal clearance and systemic inflammatory response especially plasmaTNF- α and IL-8 levels were improved. We think that further studies with largersample size and longer follow-up will provide more detailed data about theimprovements in systemic inflammation.
