Taiwan Interstitial Lung Disease Multi-center Investigation and Registry

The Taiwan Interstitial Lung Disease (ILD) Multi-center Investigation and Registry aims to evaluate the long-term outcomes of patients with fibrotic interstitial lung disease. This prospective observational registry will collect comprehensive clinical data from multiple centers, including epidemiological information, comorbidities, questionnaire results, routine blood tests, biochemical tests, pulmonary function tests, echocardiograms, and cardiopulmonary exercise tests (CPET), all following a standardized protocol. Key components of the registry include annual HRCT scans, annual CPETs, biobank blood samples, and biannual echocardiograms and pulmonary function tests. The main questions the registry aims to answer are: 1. Differences in all-cause mortality among ILD patients of different etiologies. 2. Differences in the annual risk of acute exacerbation among ILD patients of different etiologies. 3. Effectiveness of current anti-fibrotic drugs in treating IPF and ILD of different etiologies. 4. Predictive ability of HRCT imaging features for mortality risk in ILD patients. 5. Impact of comorbidities on the mortality risk of ILD patients. 6. Predictive ability of biomarkers for disease progression and mortality.
