Lung Diseases, Obstructive: current evidence & treatments

Structured physical activity and exercise interventions show significant benefits in obstructive lung diseases. In asthma, structured physical activity improves FEV1% predicted by 5.79 and quality of life (PAQLQ) 1. In idiopathic pulmonary fibrosis, structured exercise improves 6-minute walk distance by 38.62 m 2. For COPD, water-based Liuzijue exercise is most effective for improving FEV1%pred (MD 9.51) 23, and IoT-assisted pulmonary rehabilitation protocols are being investigated 5. COPD patients also exhibit heightened sympathetic nerve activity compared to healthy adults 9.

Pharmacological and management strategies vary. Anti-inflammatory reliever therapy (AIR) reduces severe exacerbations compared to SABA-only in asthma 14. Casirivimab plus imdevimab reduces hospitalization or death in COVID-19 patients with and without asthma 6. In IPF, pirfenidone reduces lung cancer incidence by 73% (RR 0.39) 17. For pulmonary embolism, ultrasound-facilitated catheter-directed alteplase reduces early recurrence 20. Telemedicine strategies, especially combined approaches, improve asthma control and quality of life 18. However, 14% of COPD patients decline or discontinue long-term PAP therapy 10.

Genetic and environmental factors contribute to disease risk. HLA-DPA1 and HLA-DPB1 are downregulated in pediatric asthma with high diagnostic value 11. FAM13A variants influence tissue destruction in COPD and fibrotic remodeling in pulmonary fibrosis 13. Maternal free vitamin D is linked to offspring asthma risk 7. Prenatal beta-2-agonist exposure is associated with increased ASD risk (aOR 1.34) 16. Ultra-processed food consumption is associated with asthma in children 3. PM2.5 exposure may increase asthma risk in susceptible individuals 22. The respiratory microbiome offers insights for precision treatment 21.
