What this Trial Is About
This research aims to evaluate whether adding capillaroscopy to standard care improves the diagnosis of Pulmonary Interstitial Disease (PID) related to connective tissue diseases. The study focuses on patients newly diagnosed with PID, investigating if capillaroscopy can help detect microvascular abnormalities and speed up diagnosis within three months. This approach may help guide earlier and more appropriate treatment. The study is observational and interventional with diagnostic testing. Participants will undergo a capillaroscopy during a special consultation where a video capillaroscope magnifies capillaries at the base of the nail. This examination takes about twenty minutes. Other tests such as chest CT scans, respiratory function tests, and immunological assessments will be performed as part of routine care. The study collects data and completes evaluations within three months after enrollment. During the study, patients complete a questionnaire and undergo capillaroscopy within the first month after consent. After three months, the pulmonologist reviews all test results to determine the likely cause of PID. Researchers measure the proportion of abnormalities found in capillaroscopy and consider factors like smoking and alcohol consumption. The total study duration for participants is three months, including initial tests, capillaroscopy, and follow-up evaluation.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Up to 3 months
Participants undergo capillaroscopy and may complete questionnaires to help identify characteristics of their pulmonary interstitial disease. Additional tests as part of routine care are reviewed to help determine the diagnosis.
1 capillaroscopy visit and 1 questionnaire completion visit within the first month; additional assessments as part of routine care
Duration - After 3 months
After all tests are completed and results compiled, participants are followed up by their pulmonologist to finalize the diagnosis of their pulmonary interstitial disease.
