About the trial
What the trial wants to find out
Ultrasound evaluation of the temporal and axillary arteries is currently well recognized in the field of giant cell arteritis (GCA), a disease primarily affecting medium- and large-caliber vessels. Structural ultrasound abnormalities are now well described in this pathology, but their association with relapse and clinical concordance is unknown. There is currently a follow-up score (the OGUS score) for medium- and large-caliber arteries that could also predict the clinical course of the disease.
The group in the trial
- patients with giant cell arteritis at diagnosis
patients routinely monitored for their disease, and who typically benefit from temporal artery ultrasound as part of their disease. Recruitment will be facilitated by the fact that these are "general population" patients with suspected giant cell arteritis.
