A disintegrin‐like and metalloproteinase with thrombospondin‐1 (ADAMTS‐1) levels in gingival crevicular fluid correlate with vascular endothelial growth factor‐A, hypoxia‐inducible factor‐1α, and clinical parameters in patients with advanced periodontitis

Background ADAMTS (a disintegrin‐like and metalloproteinase with thrombospondin) are a family of proteinases that are structurally similar to the family of matrix metalloproteinases with critical roles in damage and repair of the extracellular matrix. Their functions are closely related to inflammation, hypoxia, and vascularization. Our aim was to determine levels of ADAMTS‐1 in gingival crevicular fluid (GCF) in patients with advanced periodontal diseases and identify their association with hypoxia‐inducible factor‐1alpha (HIF‐1α), vascular endothelial growth factor (VEGF‐A), and clinical parameters of periodontitis. Methods The study consisted of three groups: healthy individuals (control; n = 20), generalized chronic periodontitis (CP; n = 21), and generalized aggressive periodontitis (GAgP; n = 20). Clinical parameters were measured. Levels of ADAMTS‐1, VEGF‐A, and HIF‐1α in GCF and serum were quantified by enzyme‐linked immunosorbent assay (ELISA) and reported as total amounts and concentration. Results ADAMTS‐1 total amount in GCF were significantly higher in patients with CP and GAgP compared with healthy individuals (P
