At baseline, median MRP8/14 levels were higher in patients with TA than healthy controls [7353 (4524 to11283) vs 4896 (3194 to 8474.5) ng/ml, p = 0.011].

Inclusion criteria for the qualitative analysis were (1) <sup>18</sup>F-FDG PET used to assess the disease activity, (2) The use of the ACR criteria for the diagnosis of TAK, (3) No case mixed vasculitis (i.e., no giant cell arteritis), and (4) CRP concentration and clinical disease activity available.
Eighteen patients received a clinical diagnosis with thirteen cases meeting 1990 ACR criteria for TAK (all female, 77% Caucasian, age at diagnosis 39 years) included in this analysis.
For classification, sensitivities and specificities for ACR classification criteria were, respectively, 81.1% and 94.9% for GCA; 73.6% and 98.3% for Takayasu's arteritis; 65.6% and 88.7% for granulomatosis with polyangiitis; 57.0% and 99.8% for eosinophilic granulomatosis with polyangiitis; 40.6% and 87.8% for polyarteritis nodosa; 28.9% and 88.5% for microscopic polyangiitis; and 72.7% and 96.3% for IgA-vasculitis.Overall sensitivity was 67.1%.
These associations include ERAP1, CCR1-CCR3, STAT4, KLRC4, GIMAP4, and TNFAIP3 in Behçet's disease; BLK and CD40 in Kawasaki disease; SERPINA1 and SEMA6A in antineutrophil cytoplasmic antibody associated vasculitides; IL12B and FCGR2A/ FCGR2A in Takayasu arteritis; and CECR1 in a newly defined vascular inflammatory syndrome associated with adenosine deaminase (ADA2) deficiency.

The mRNA expression of S100A8, S100A9, S100A12 and TLR4 were higher, while expression of RAGE and HSP70 were lower in TA as compared to healthy controls.
Amino acid residues of histidine at position 171 and phenylalanine at position 67, both of which are located in antigen binding grooves of the HLA-B protein, were associated with TAK susceptibility (P ≤ 3.8 × 10(-5)) with a significant difference from other amino acid variations (ΔAIC ≥ 9.65).
RESULTS In patients with Takayasu arteritis, the erythrocyte sedimentation rate (ESR), CRP, CRP/albumin ratio, red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte-lymphocyte ratio (MLR) were significantly higher, and albumin and MPV were significantly lower compared with controls.
To investigate serum levels of a panel of angiogenic inducers (VEGF, FGF-2, Angiopoietin 1, -2, soluble VCAM-1) and inhibitors (angiostatin, endostatin, pentraxin-3) in patients with giant cell arteritis (GCA) and Takayasu's arteritis (TAK), in order to gain further insights into the molecular mechanisms driving angiogenesis dysregulation in large-vessel vasculitis (LVV).
Identification of Susceptibility Loci in IL6, RPS9/LILRB3, and an Intergenic Locus on Chromosome 21q22 in Takayasu Arteritis in a Genome-Wide Association Study.
Regarding circulating chemokines in TA, serum/plasma levels of IL-8 (CXCL8), CCL2 and CCL5 were shown to be elevated in TA patients compared with healthy controls as well as in TA patients with active disease compared with those in remission.

PON1 activity was significantly lower for PON in TA vs. controls (136.14 vs. 322.79 μmol min(-1) ml(-1), P=0.001, showing a decreasing activity in all genotypes in TA patients with respect to the control subjects.

Although pentraxin-3 is superior to erythrocyte sedimentation rate and CRP, we need more reliable biomarkers to reflect vascular wall inflammation in patients with TAK.
