REVIEW

Raluy-Callado and other authors use observational studies in associating bronchitis with the COPD phenotype and the generated outcomes with inconsistent outcomes based on mortality and exacerbations. The links are crucial because they contain a substantial impact on disease burden. The reason is that despite COPD is a chronic disease, the presence of acute exacerbations and the rate of occurrence is used in determining the progression of the disease. . The exacerbation of COPD is minimal such as chronic bronchitis are linked to the context of impairing quality life and the increased desperation of the function of the lungs. This subsequently increases the chance of admissions to hospitals for patients with chronic bronchitis (CB). The bronchial biopsies, as well as induced sputum, indicate that inflammation of the lung occurs in all cigarette smokers.

The enhanced abnormity of the response to inflation towards inhaled toxic particles moves beyond the normative aspect of protractive inflammatory as a response and the feature of COPD that late causes the lungs’ injury. The adaptive and innate inflammatory in the context of immune responses is involved in epithelial inflammation and the severity of chronic bronchitis. Smoking cigarettes increases the circulation of neutrophil leucocytes, and this, in return, causes the sequestration of the neutrophils in lung capillaries, causing a defamatory decrease.6(pp. 931) Moreover, smoke from cigarettes results in the direct effect of stimulation on granulocyte produced in the bone marrow. The cause is mediated by the other factors that the inflammation from the macrophages.
