58-year-old with daily cough and blood-streaked sputum
A 58-year-old woman with long-standing rheumatoid arthritis is evaluated for several months of daily productive cough and two small episodes of blood-streaked sputum this week. She has had three outpatient antibiotic courses for “bronchitis” over the past year. Temperature is 36.9 C, blood pressure 124/72 mm Hg, pulse 88/min, and oxygen saturation 95% on room air. Bibasilar coarse crackles are present. Hemoglobin is 12.4 g/dL, and chest radiograph shows only mild chronic basilar markings. Which of the following is the most appropriate next step in management?

Explanation
Clinical Pearl:
In adults with chronic productive cough, recurrent respiratory infections, and even a normal or nonspecific chest radiograph, bronchiectasis is best confirmed with high-resolution chest CT. Mild hemoptysis in this setting usually prompts imaging first, with bronchoscopy reserved for selected cases.
Explanation:
This patient’s chronic daily sputum production, recurrent infective exacerbations, scant hemoptysis, and crackles raise strong concern for bronchiectasis, and rheumatoid arthritis is a recognized associated condition. Current practice is to confirm suspected bronchiectasis with high-resolution CT, because plain radiographs can be normal or only subtly abnormal despite clinically important disease. High-dose inhaled corticosteroids are not routine treatment for bronchiectasis unless there is a separate indication such as asthma or eosinophilic airway disease. Empiric four-drug tuberculosis therapy is inappropriate because the vignette does not suggest active TB and treatment should not precede diagnostic evidence. Bronchoscopy is not the best initial test here; it is more useful for focal obstruction, unexplained or larger-volume hemoptysis, or when CT leaves an important question unanswered. Reassurance alone misses a likely structural airway disorder that changes long-term management, including airway clearance and evaluation for chronic infection and underlying causes.
