New study aims to predict relapse in common blood vessel disease
NCT ID NCT07246577
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is looking for 340 people with suspected giant cell arteritis (GCA), a condition that causes inflammation in blood vessels and is usually treated with long-term steroids. The goal is to find better ways to predict who will have relapses and to monitor the disease using ultrasound and blood tests. By improving these tools, doctors hope to personalize treatment and reduce side effects from steroids.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
A new cohort will be recruited. Individuals presenting with suspected GCA at Sahlgrenska University Hospital in Gothenburg, Sweden, or at Skaraborg Hospital Skövde, Sweden, will be invited to participate in the study. Diagnostic ultrasound examinations and follow-up assessments will be conducted at Sahlgrenska University Hospital in Gothenburg. After study enrollment, participants diagnosed with GCA will be followed for 12 months, with scheduled visits at 1, 6, and 12 months after initiation of treatment. If clinical relapse of GCA is suspected outside of the scheduled visits, an additional examination will be performed. Participants who are not diagnosed with GCA will be followed up by telephone after 6 months to confirm diagnostic status.
