Thrombomodulin blood test to rule out giant cell arteritis in PMR
Part of Bones, joints & muscles, Brain & nervous system, Heart & circulation, Immune system & allergy, Skin clinical trials.
This study tests whether a blood test for a protein called thrombomodulin can help rule out giant cell arteritis (a blood vessel inflammation) in people with polymyalgia rheumatica. It involves a blood draw and a one-time imaging scan to look at your blood vessels.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are over 50 years old.
- You have been diagnosed with polymyalgia rheumatica (PMR) based on specific symptoms like morning stiffness and certain blood test results.
- You have not taken any steroids or immune-suppressing drugs in the past month.
- You do not have an active infection, cancer, or other autoimmune disease (like rheumatoid arthritis).
- You are willing to have a vascular imaging scan (CT or PET) to check for giant cell arteritis.

This study looks at people newly diagnosed with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA) and uses their health and treatment information to learn what predicts how well treatment works. It may help your care in the future by improving which patients respond best and how.
This trial tests if new imaging methods can help diagnose and treat polymyalgia rheumatica (PMR). It may be for you if you're over 50, have pain in your shoulders or hips, and haven't taken steroids for PMR in the last 2 months.
This study looks at blood markers related to DNA changes in people with polymyalgia rheumatica (PMR). It aims to better understand the condition and may help guide future treatments.
This study is for people with certain rheumatic conditions (like arthritis, lupus, or vasculitis) and for healthy volunteers. It aims to learn more about these diseases and improve how they are treated.
This study looks at immune cells called B-cells in people with giant cell arteritis (a condition causing inflammation in blood vessels) and other immune disorders, to see if targeting these cells could be a new treatment. It involves imaging and blood tests.
This trial tests whether a drug called bosentan, which is usually used for other conditions, can help calm the inflammation in giant cell arteritis and reduce symptoms. You would take it in addition to your usual treatment, and it might help lower the dose of steroids you need.
