Evaluating a Fast-track Diagnostic Pathway for Giant Cell Arteritis in People Over 50

What this Trial Is About

Giant Cell Arteritis GCA is an inflammation of artery walls mainly affecting people over 50 years old. The diagnosis can be difficult due to non-specific symptoms like headaches, jaw pain, and scalp tenderness, but it is important to diagnose quickly to avoid serious complications such as vision loss or stroke. Advances in ultrasound technology have improved early diagnosis by identifying a characteristic halo sign on temporal arteries, potentially reducing the need for biopsies. This research evaluates a fast-track diagnostic pathway designed to speed up the diagnosis of GCA. Patients suspected of having GCA undergo ultrasound exams of temporal and axillary arteries. If inflammation is seen on both sides, biopsy may be avoided. If ultrasound is negative or inconclusive, biopsy is performed. This approach aims to reduce diagnosis time from about 10 days to just one day and to minimize hospital stays and biopsies. Participants suspected of GCA will be assessed through clinical signs, ultrasound imaging, and if needed, biopsy. Researchers will measure the time from initial suspicion to ultrasound results and corticosteroid treatment start. They will also track cases with alternative diagnoses and compare ultrasound and biopsy findings. The study continues until March 2027 and seeks to improve early diagnosis and care for people with this condition.
