Exploring biomarkers in pulmonary fibrosis and sarcoidosis

Host-microbiome Interactions in the Quest for Fibrosing ILD Biomarkers That Rule Acceleration

Observational Universidade do Porto · NCT05635032

This study is trying to find new biological markers in patients with pulmonary fibrosis and sarcoidosis to see how these markers can help understand the disease better and improve treatment options.

What this trial studies

FIBRALUNG is a prospective cohort study that collects biological samples from patients with pulmonary fibrosis and related conditions to investigate the molecular factors influencing clinical outcomes, acute exacerbations, and mortality. The study aims to identify common pathways in fibroproliferative diseases, particularly between idiopathic pulmonary fibrosis and fibrotic hypersensitivity pneumonitis. By analyzing these samples, researchers hope to discover new biomarkers that indicate disease progression and could lead to targeted therapies. Additional patients with other interstitial lung diseases and sarcoidosis will also be included for further analysis.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18-80 with a recent HRCT scan showing significant lung fibrosis and who are treatment-naïve.

Not a fit: Patients who cannot provide informed consent or are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the development of new biomarkers and targeted therapies for patients with pulmonary fibrosis and sarcoidosis.

How similar studies have performed: Other studies have shown promise in identifying biomarkers for pulmonary diseases, but this specific approach is novel.
