The Analysis of Matrix Metalloproteinase-9 and Tissue Inhibitor Matrix Metalloproteinase-1 Levels in the Amniochorion Membrane Patients on Premature Rupture of Membranes

Introduction: MMP-9 is essential for extracellular matrix remodeling, which affects the incidence of premature rupture of membranes. In addition, decreased and increased levels of TIMP-1, a preferential MMP-9 inhibitor, have been reported to be associated with premature rupture of membranes because it showed an imbalance in the MMP-9 or TIMP-1 levels. This study aims to analyze MMP-9 and TIMP-1 levels in amniochorion membrane patients on premature rupture of membranes. Methods: An analytic observational study was conducted on 70 subjects. The MMP-9 and TIMP-1 levels in the amniochorion membrane were determined by ELISA. Results: The results of this study indicate that the amniochorion membrane in the incidence of premature rupture of membranes is characterized by increased levels of MMP-9, while TIMP-1 levels do not differ between the incidence of premature rupture of membranes. Conclusion: Based on the research that has been done, it can be concluded that there are differences in protein levels of MMP-9 but there are no differences in protein levels of TIMP-1 in premature rupture of membranes
