1. Background
COPD remains a leading cause of morbidity and mortality worldwide, affecting ~300 million individuals (WHO). It is characterized by airflow limitation that is not fully reversible, driven primarily by chronic inflammation triggered by exposure to noxious particles or gases (e.g., tobacco smoke, biomass fuel).

2. Diagnostic Biomarkers
Biomarker Clinical Use Sensitivity / Specificity
FVC, FEV1 Spirometry; GOLD staging High
FEV1/FVC ratio (<0.70) Diagnostic threshold 100% sensitivity in symptomatic adults
C-reactive protein (CRP) Systemic inflammation; exacerbation risk Moderate
Neutrophil count Acute exacerbations Variable
Key Points:
Spirometry remains the gold standard.
Emerging biomarkers may aid in prognosis and therapy tailoring.
4. Management
4.1 Pharmacologic Therapy
Drug Class First-line (GOLD A/B) Second-line (GOLD C/D)
Short‑acting β₂ agonists SABA for symptom relief SABAs + LABAs
Long‑acting muscarinic antagonists (LAMAs) Add-on in GOLD B/C LAMA monotherapy or add-on
Long‑acting β₂ agonists (LABAs) Add-on in GOLD A/B LABA+LAMA combination
Inhaled corticosteroids (ICS) Consider if eosinophils >300/µL or frequent exacerbations Use with caution; risk of pneumonia
Triple therapy (LABA + LAMA + ICS) is indicated for patients in GOLD 4 or those with persistent symptoms and exacerbations despite dual therapy, especially with high blood eosinophil counts (> 400 cells/µL).
Avoid unnecessary long‑term systemic corticosteroids unless an acute exacerbation occurs.
3. Management of comorbidities
Comorbidity Key considerations for COPD care
Asthma (asthma–COPD overlap) Treat with inhaled corticosteroids; maintain separate asthma action plan.
Heart failure Monitor fluid status; avoid β‑blockers that worsen airflow, use cardioselective agents.
Chronic kidney disease Adjust diuretics and ACE inhibitors; consider renal dosing of medications.
Osteoporosis Calcium/vitamin D supplementation; bisphosphonates if indicated; screen for fractures.
Depression/anxiety Screen regularly; integrate psychotherapy, SSRIs with caution (QT prolongation).

1. Assess COPD severity:
- GOLD A/B/C/D + SGRQ/TMIGS/BCSS scores.
- If >2 exacerbations/year OR FEV1 <50% predicted → Consider pharmacologic therapy.
2. Pharmacologic options (simplified):
a) Bronchodilators (short‑acting / long‑acting β2 agonists, antimuscarinics).
b) Inhaled corticosteroids (ICS) if eosinophils >300/µL or ≥2 exacerbations.
c) Long‑term antibiotics (azithromycin) if frequent exacerbations.
3. Monitor response:
- Repeat SGRQ/TMIGS/BCSS at 6–12 months.
- If improvement <5 units in SGRQ → Reassess therapy.
4. Non‑pharmacologic:
a) Pulmonary rehab (sessions 2×/week).
b) Smoking cessation counseling + pharmacotherapy.
c) Vaccinations: influenza, pneumococcal.
5. Evaluate for advanced therapies:
- If FEV1 <30% predicted or GOLD stage IV despite therapy → refer to transplant center.
6. Documentation:
- Record all scores and changes in progress notes.
- Discuss with patient the importance of adherence and follow‑up appointments.

Key Takeaway:
Incorporate validated QoL tools into routine visits, set clear improvement targets, and combine pharmacologic, rehabilitative, and psychosocial interventions to enhance overall well‑being for patients with COPD.
