Abstract
|
|
|
|
Chronic bronchitis (CB) is known to be one of the most important phenotypes of chronic obstructive pulmonary disease (COPD) which is associated with poor health-related quality of life, poor lung function, frequent exacerbation and higher mortality. As the classic definition of CB has several limitations and bias, there have been recent efforts to define CB alternatively, using SGRQ and CAT scores. Most important risk factor of CB is reported to be cigarette smoking, whereas risk of E-cigarette and early life disadvantages have gained interests. Besides previous efforts of managing CB with mucoactive drugs and physiotherapy, recent bronchoscopic interventions to ablate goblet cell hyperplasia have been introduced, and presented with promising results.
