COPD Flashcards
How does COPD differ from asthma
COPD
1. Neutrophillic
2. LTB4, IL8, and TNFa
3. Squamous metaplasia of epithelium
4. Parenchymal destruction
5. GC have variable effect
Asthma

2. LTD4, IL4, IL5, others
3. Fragile epithelium
4. Thickening of basement membrane
5. GC inhibit inflammation
