Active-Matrix Metalloproteinase-8, Myeloperoxidase in Relation With Periodontics, Preterm Birth.

Area of Science:

• Obstetrics and Gynecology
• Periodontology
• Biochemistry

Background:

• Preterm birth and pre-eclampsia are significant adverse pregnancy outcomes.
• Matrix metalloproteinases (MMPs) and myeloperoxidase (MPO) are implicated in inflammatory processes.
• The role of specific biomarkers like active-matrix metalloproteinase-8 (aMMP-8) and myeloperoxidase (MPO) in pregnancy complications requires further investigation.

Purpose of the Study:

• To compare serum and placental levels of aMMP-8 and MPO in women with term delivery, preterm birth, and preterm birth with pre-eclampsia.
• To examine the relationship between these biomarkers and clinical periodontal parameters in different pregnancy outcomes.

Main Methods:

• A cross-sectional study involving 173 deliveries (full-term, preterm, preterm with pre-eclampsia).
• Clinical periodontal measurements were recorded.
• Serum and placenta samples were analyzed for aMMP-8 (using IFMA) and MPO (using ELISA).

Main Results:

• The preterm birth with pre-eclampsia group showed significantly higher probing depth and clinical attachment loss compared to other groups.
• Serum aMMP-8 and MPO levels were elevated in the preterm birth with pre-eclampsia group.
• Placental aMMP-8 levels were higher in the control (full-term) group compared to the preterm birth with pre-eclampsia group.

Conclusions:

• Elevated serum aMMP-8 and MPO, and placental aMMP-8 may be associated with adverse pregnancy outcomes.
• Clinical periodontal status did not demonstrate significant associations with the measured proteolytic and oxidative biomarkers in this study.
