Using lung ultrasound to detect lung disease in rheumatoid arthritis patients

dEtection of rheumAtoid aRthritis - Interstitial Lung dIseasE by Thoracic ultRasound

Observational University Hospital, Tours · NCT06235645

This study is testing if lung ultrasound can help find lung disease in people with rheumatoid arthritis who have certain risk factors, comparing it to the usual chest CT scans.

What this trial studies

This observational study aims to evaluate the effectiveness of lung ultrasound (LUS) as a screening tool for detecting interstitial lung disease (ILD) in patients with rheumatoid arthritis (RA) who have specific risk factors. Participants will undergo routine assessments, including chest CT and pulmonary function tests, and those meeting the inclusion criteria will be offered participation. The study will compare the sensitivity and specificity of LUS against the current gold standard, chest CT, to determine its viability as a non-invasive and cost-effective alternative for monitoring lung health in RA patients.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with a diagnosis of rheumatoid arthritis and at least two risk factors for developing interstitial lung disease.

Not a fit: Patients with congenital lung diseases or other autoimmune conditions associated with RA that can lead to ILD may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more accessible method for early detection of lung disease in rheumatoid arthritis patients.

How similar studies have performed: While lung ultrasound has shown promise in other conditions, this specific application in rheumatoid arthritis is relatively novel and has not been extensively tested.
