Chronic Cough (>8 wk) in Immunocompetent Adults

•   Evaluate for red flags: Evaluate for red flags and consider CXR. If red flags present or concerning findings on CXR, proceed with a more urgent workup

•   Etiology and diagnosis: Consider common causes of subacute to chronic cough: See Table 2.4

TABLE 2.4 • Differential Diagnosis for Causes of Subacute to Chronic Cough

•   Refractory chronic cough:

-   If symptoms continue despite evaluation/empiric treatment for common causes, consider less common causes of chronic cough. Differential diagnosis:

•   Infectious: Mycobacterium tuberculosis, Nontuberculous mycobacterium (including Mycobacterium avium complex (MAC), Mycobacterium kansasii, and Mycobacterium abscessus), endemic fungal infections

•   Cardiac: LV failure, dilated left atrium, mitral stenosis

•   Other: Post-infectious cough, chronic aspiration, sarcoidosis, laryngeal spasm, non-asthmatic eosinophilic bronchitis, allergic bronchopulmonary aspergillosis (ABPA), psychogenic cough

-   Workup may include: Labs (including CBC with differential to evaluate for eosinophilia), repeat CXR, advanced imaging, sputum cultures, PFTs, sleep apnea testing, TTE, referral to pulmonary/ENT/ID, bronchoscopy
