Clinical Trial: Association of Serum VEGF-A and VCAM-1 Levels With Nailfold Capilleroscopic Alterations in Alopecia Areata

U.S., March 31 -- ClinicalTrials.gov registry received information related to the study (NCT07499713) titled 'Association of Serum VEGF-A and VCAM-1 Levels With Nailfold Capilleroscopic Alterations in Alopecia Areata' on March 24.

Brief Summary: The goal of this observational study is to learn about microvascular changes and hair follicle activity in patients with alopecia areata. The main questions it aims to answer are:

Do blood levels of markers related to blood vessel formation (VEGF-A) and inflammation (VCAM-1) differ between patients with alopecia areata and healthy individuals?

Is there a link between these blood markers and structural changes in the nailfold capillaries?

How do these markers relate to specific trichoscopic signs...
