There are some divergent data concerning the role of matrix metalloproteinase (MMP)-2, MMP-9 and tissue inhibitor of MMP (TIMP)-2 in the pathogenesis of alcoholic cirrhosis (AC) and chronic pancreatitis (CP). Our objective was to evaluate the activity of MMP-2, MMP-9 and TIMP-2 serum levels in patients with AC and CP. Twenty-one patients with diagnosis of AC and twenty-two with CP admitted to the outpatient clinic for a control visit were enrolled. All results were compared with age and sex-matched control group (n=19). The sera obtained from venous blood were stored at -70°C for further analysis. Activity of MMP-2 and MMP-9 were evaluated with gelatin zymography, TIMP-2 serum level was analyzed with the usage of ELISA method. A significant decrease of serum MMP-2 activity was noted in sera of AC and CP patients in comparison with control. Activity of MMP-9 was elevated only in CP patients and TIMP-2 serum level was elevated only in AC patients. Decreased activity of MMP-2 in AC patients can contribute to cirrhosis development. The high level of MMP-9 in serum related to CP patients theoretically can exacerbate the inflammatory process within the pancreas.
