Which symptom is associated with chronic cough and night sweats in respiratory disease?

• A. Emphysema
• B. Sarcoidosis
• C. Bronchitis
• D. Asthma

Answer: (B)

Chronic cough and night sweats are particularly indicative of sarcoidosis, which is a systemic granulomatous disease that predominantly affects the lungs but can involve multiple organ systems. In sarcoidosis, the formation of granulomas—clusters of inflammatory cells—in the lungs can lead to persistent respiratory symptoms, including a chronic cough. Night sweats are often seen in systemic diseases and suggest an active inflammatory process, which aligns with the pathophysiology of sarcoidosis. While emphysema, bronchitis, and asthma can also present with cough, they typically do not associate with night sweats in the same manner as sarcoidosis. Emphysema tends to cause a more chronic, productive cough without systemic symptoms like night sweats. Chronic bronchitis may involve a cough and can sometimes lead to bouts of infection, but night sweats would not be a common symptom for most patients. Asthma often causes a cough and wheezing primarily related to airway hyperreactivity, but it is less likely to be associated with systemic symptoms such as night sweats. Therefore, the combination of chronic cough and night sweats is most characteristic of sarcoidosis, highlighting its systemic implications.
