Aim:
Evaluate the effects of smoking on chemokines of the human chronic periodontitis (CP).
Materials And Methods:
Gingival samples were obtained from 23 smokers (S) and 20 non-smokers (NS) diagnosed with CP. Periodontal examination was performed. The CCL2, CCL3, CCL5, CCL19, CCL20, and CXCL8 chemokine levels were measured in gingival tissues using enzyme-linked immunosorbent assay. Chemokines were compared between S and NS, and were correlated with the number of cigarettes per day (C/day) and time of the smoking habit in years (SH/years).
Results:
CCL3 and CXCL8 of S were significantly smaller than that found in NS subjects, whereas the CCL5 levels increased in the S group. Negative correlations could be observed between CCL19 levels and SH/year.
Conclusion:
Smoking suppresses the immune response which may contribute to an increased susceptibility to periodontal disease in smokers.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
