Is it true that chronic obstructive pulmonary disease is characterized by chronic inflammation in the airways and an increase in systemic inflammation?

Yes. Chronic obstructive pulmonary disease is widely characterized by persistent airway inflammation as well as elevated systemic inflammatory responses that contribute to its extrapulmonary manifestations.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved literature consistently supports the pathophysiology of COPD involving both local airway/pulmonary inflammation and pronounced systemic inflammation. None of the papers refute this foundational premise.
