Tests to diagnose takayasu Arteritis tend to be: Panaortografía and arteriogram-selective, F-Fluorodeoxyglucose PET, Doppler Ultrasound, high resolution MRI and magnetic resonance angiography, Biopsy of the arterial lesions.
In the active disease usually normocytic / normochromic anaemia of chronic inflammatory process, thrombocytosis, hypergammaglobulinemia, polyclonal, increase of ESR and CRP. However, in the 25%-50% of cases these results can be misleading and do not correlate with disease activity, so that we will have to help us also of clinical data and testing imagenpara perform a comprehensive evaluation of each patient. Also, it has been described an increase of beta-2 microglobulin, IL-2, IL-6 , IL-8, IL-18, metalloprotease 3 and 9, and pentraxin-3 as biological markers of disease activity. Patients with ATK inactive have high serum levels of selectin-soluble E, molecule 1, vascular cell adhesion (VCAM - 1) and cell adhesion molecule-1 intercellular (ICAM-1), which could indicate persistent vasculopathy in the disease is apparently inactive.
