COPD study investigates why patients struggle to fight lung infections
NCT ID NCT02655302
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether a weak immune response to bacteria in COPD patients leads to more lung infections and flare-ups. Researchers collected sputum, blood, and nasal swabs from 23 hospitalized COPD patients during a flare-up and again 8 to 16 weeks later. The goal was to measure specific immune signals (IL-17 and IL-22) to understand why COPD patients are prone to bacterial infections.
