COPD management is evolving toward precision strategies that are focused on reducing exacerbations, improving lung function, and slowing disease progression. GOLD 2025 emphasizes identifying type 2 inflammation—commonly via blood eosinophil count (BEC)—to guide personalized treatment.
ICS-based therapy is more effective in patients with elevated BEC. GOLD advises considering ICS when BEC is >100 cells/μL and strongly recommends it at ≥300 cells/μL. For patients at high risk of exacerbations, triple therapy (inhaled corticosteroid [ICS] / long-acting β₂-agonist [LABA] / long-acting muscarinic antagonist [LAMA]) provides greater benefit over dual combinations, with consistent reductions in exacerbation rates and mortality.
Beyond inhaled therapy, novel agents such as PDE4 inhibitors and biologics targeting inflammatory pathways are under evaluation. These aim to address persistent symptoms and frequent exacerbations, aligning with biomarker-guided precision medicine.
Earlier identification of high-risk individuals supports a shift to proactive care. The concept of low disease activity (LDA)—defined by the absence of exacerbations, symptom worsening, or lung function decline—is emerging as a practical goal in COPD management. This evolving treatment paradigm encourages the routine use of biomarkers and timely, targeted interventions to achieve long-term stability.
How can eosinophil-guided strategies be routinely implemented to personalize inhaled therapy in COPD? What steps are needed to embed earlier, targeted interventions into COPD guidelines and care pathways?
