Investigating the JAK/STAT Pathway in Sarcoidosis Granuloma Cells

Expression and Role of the JAK/STAT Pathway in Sarcoidosis Granuloma Cells

Assistance Publique - Hôpitaux de Paris · NCT04751279

This study is trying to see if a specific pathway in the body is linked to severe sarcoidosis in patients who don't respond to regular treatments, to find out who might benefit from new targeted therapies.

What this trial studies

This observational study aims to explore the role of the JAK/STAT signaling pathway in patients with sarcoidosis, particularly those with severe forms of the disease that do not respond to standard treatments. Researchers will evaluate blood samples from patients diagnosed with mediastinopulmonary sarcoidosis to assess the activation of the JAK/STAT pathway and its relationship with granuloma formation and disease severity. The study seeks to identify which patients may benefit from targeted therapies aimed at this pathway.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with mediastinopulmonary sarcoidosis at various stages of pulmonary involvement.

Not a fit: Patients who are pregnant or those who oppose participation in the study will not benefit from this research.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for patients with severe sarcoidosis.

How similar studies have performed: Other studies have suggested the potential of targeting the JAK/STAT pathway in sarcoidosis, but this specific approach is still under investigation.
