Negative correlation between D-dimer and plasminogen activator inhibitor-1 levels is absent in obese women.

Obesity is characterized by alterations in haemostatic processes that lead to a prothrombotic state. D-dimer (D-Di) is the last product of the fibrinolysis and may reflect the haemostatic balance. As the plasminogen activator inhibitor (PAI)-1 is the main inhibitor of fibrinolysis and it is elevated in obese, we hypothesize that negative correlation exists between PAI-1 and D-Di.

Evaluation of plasmatic MMP-8, MMP-9, TIMP-1 and MPO levels in obese and lean women.

Objectives: To compare the plasma concentrations of matrix metalloproteinase (MMP)-9, tissue inhibitor of MMP (TIMP)-1, MMP-8, and myeloperoxidase (MPO) for obese and lean women.

Design And Methods: We recruited 30 lean and 36 obese women without comorbidities. The MMP-9, TIMP-1, and MMP-8 levels were measured using enzyme-linked immunosorbent assay (ELISA).
