Chronic asthmatic bronchitis is a similar, overlapping condition characterized by chronic productive cough, wheezing, and partially reversible airflow obstruction; it occurs predominantly in smokers with a history of asthma. These diseases can block air flow in the lungs and cause breathing problems. They’re also the two main conditions of chronic obstructive pulmonary disease (COPD).

Causes, risk … Normal airway color and architecture (in a child with mild tracheomalacia). Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease with different clinical and pathophysiologic phenotypes. Hyperplasia and hypertrophy of the goblet cells (mucous gland) of the airway are the common pathologic features of chronic bronchitis.Chronic inflammation due to lymphocyte infiltration is seen on microscopy.. Pathophysiology Pathogenesis. It has numerous clinical consequences, including an accelerated decline in lung function, greater risk of the development of airflow obstruction in smokers, a predisposition to lower respiratory tract infection, higher exacerbation frequency, and worse overall mortality. The establishment of the diagnosis of chronic bron-chitis is often neglected when other overt spe-cific disease is present, although it is impor-tant to identify all diagnoses so that complete therapy can be instituted. Acute bronchitis, also called a chest cold, usually improves within a week to 10 days without lasting effects, although the cough may linger for weeks. 3. View Media Gallery.

Figure B is an enlarged, detailed view of a normal bronchial tube. Emphysema and chronic bronchitis are airflow-limited states contained within the disease state known as chronic obstructive pulmonary disease (COPD). It has numerous clinical consequences, including an accelerated decline in lung function, greater risk of the development of airflow obstruction in smokers, a predisposition to lower respiratory tract infection, higher exacerbation frequency, and worse overall mortality. Acute bronchitis is temporary inflammation of the airways that causes a cough and mucus. First, airflow, in the range seen during a cough, can create waves of mucus. Vicious circle of bronchiectasis.
