Aspiration Bronchitis: Acute bronchitis

Aspiration Bronchitis: Acute bronchitis

Nonviral agents cause only a small part of acute bronchitis illnesses, with the most common organism being Mycoplasma pneumoniae. Study findings suggest that Chlamydia pneumoniae may be another nonviral cause of acute bronchitis. The obstructive symptoms of acute bronchitis, as established by spirometric studies, have become similar to those of mild asthma. In one study. Forced expiratory volume in one second (FEV), mean forced expiratory flow during the midst of forced vital capacity (FEF) and peak flow values dropped to less than 80 percent of the predicted values in nearly 60 percent of patients during episodes of acute bronchitis.

Recent Epidemiologic Findings of Serologic Evidence of C

Pneumoniae infection in adults with new-onset asthma imply that untreated chlamydial infections may have a function in the transition from the intense inflammation of bronchitis to the chronic inflammatory changes of asthma. Patients with acute bronchitis have a viral respiratory infection with transient inflammatory changes that create symptoms and sputum of airway obstruction. Evidence of airway obstruction that is reversible even when not infected Symptoms worse during the work but have a tendency to improve during vacations, holidays and weekends Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no signs of bronchial wheezing Evidence of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Typically related to a precipitating event, such as smoke inhalation Evidence of reversible airway obstruction even when not infected Symptoms worse during the work week but tend to improve during weekends, holidays and vacations Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no evidence of bronchial wheezing Evidence of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Typically related to a precipitating Occasion, for example smoke inhalation Asthma and allergic bronchospastic disorders, including allergic aspergillosis or bronchospasm because of other environmental and occupational exposures, can mimic the productive cough of acute bronchitis.
