Concentration of plasma MMP-9 in 30 healthy control, 12 non-VAP subjects and 30 patients with VAP who were divided into acute and remission stage by ELISA kits. MMP-9 concentration was significantly higher in the acute stage of VAP patients when compared with non-VAP subjects (p=0.0038) and healthy controls (p<0.0001); and significantly decreased after the treatment (p=0.01). There's no difference between non-VAP subjects and healthy controls (p=0.40). Plasma MMP-9 levels were significantly increased in VAP patients both in the acute (p<0.0001) and remission stages (p=0.0007), when compared with healthy controls.
