Investigational drug(s) / intervention(s)

capillaroscopy

capillaroscopy: Capillaroscopy will be performed during a specific consultation. During this examination, a device called a "video capillaroscope" is used to magnify and visualize the capillaries located at the base of the nail. The examination lasts approximately twenty minutes.

Study summary

The investigators hypothesize that in patients with a new diagnosis of Pulmonary Interstitial Disease (PID), adding capillaroscopy to standard care increases the proportion of patients receiving a diagnosis of PID-Connective Tissue Disease (PID-CTD) within the first three months of follow-up, thereby reducing the time to diagnosis and facilitating the implementation of appropriate treatment as quickly as possible. Therefore, To confirm this hypothesis, it is necessary to know the characteristics of capillaroscopy in patients with a new diagnosis of PID.
