- Pulmonary fibrosis (PF) affects up to 0.1% of the global population.
- Top causes of ILD-related PF: idiopathic PF, connective tissue disease-related ILD, sarcoidosis, and hypersensitivity pneumonitis.
- Global annual incidence of ILD-related PF has more than doubled between 1990 and 2019, now estimated at 15-20 cases per 100,000 population.
- Incidence, prevalence, and spectrum of ILD-related PF vary greatly across regions due to genetics, environment, industries, and diagnostic rigor.
- Diagnosis of PF relies on chest imaging, lung histology, and expert evaluation, which are scarce in underserved regions.
- 30-60% of patients with ILD-related PF develop progressive disease over 1-2 years.
- Annual PF care cost averages approximately US$30,000 in developed countries.
- Key steps to enhance PF care: universal health coverage, improved access to imaging and expert teams, telehealth, drug development, and expanded availability of rehabilitation, palliative care, and lung transplantation.
- Emerging techniques like gene silencing, alveolar organoids, stem cells, lung-on-a-chip, and nano-based drug delivery could transform future PF care.
- PF is a significant global healthcare challenge due to clinical heterogeneity and geographic variation.
