Aim:
The aim of this prospective study is to investigate if there is a relationship between inguinal hernia, matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinases (TIMPs).
Materials And Methods:
This case control study was performed on patients admitted to the general surgery department of Erzincan University Hospital. Four groups were created: control, indirect hernia, direct hernia, and bilateral hernia. All groups were comprised of 11 patients. Serum and tissue levels of MMP-1, MMP-2, MMP-9, MMP-13, TIMP-1, TIMP-2, TIMP-3, and hydroxyproline were evaluated.
Results:
MMPs values were significantly high at hernia groups, especially at bilateral hernia group (p < 0.05), whereas TIMPs values were significantly low at bilateral hernia group (p < 0.05). MMPs values were increasing at hernia groups in an order as control, indirect, direct, and bilateral. TIMPs values were decreasing at hernia groups in an order as control, indirect, direct, and bilateral.
Conclusion:
Increased levels of MMP-1-2-9-13 and decreased levels of TIMP-1-2-3 may have played role in the formation of inguinal hernia. Hernia is not only a local defect, but a reflection of systemic disease. This is even more significant for bilateral hernias.
Insights
Matrix metalloproteinases (MMPs) were elevated and tissue inhibitors of metalloproteinases (TIMPs) were reduced in patients with inguinal hernias, suggesting their role in hernia formation, particularly in bilateral cases.
Area of Science:
- Biochemistry
- Surgical Pathology
- Biomarkers
Background:
- Inguinal hernias are common surgical conditions.
- The role of extracellular matrix remodeling in hernia pathogenesis is under investigation.
- Matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) are key regulators of tissue remodeling.
Purpose of the Study:
- To investigate the relationship between inguinal hernia and the levels of specific MMPs and TIMPs.
- To compare MMP and TIMP levels in different types of inguinal hernias (indirect, direct, bilateral) and controls.
Main Methods:
- A case-control study involving 11 patients in each of four groups: control, indirect hernia, direct hernia, and bilateral hernia.
- Serum and tissue levels of MMP-1, MMP-2, MMP-9, MMP-13, TIMP-1, TIMP-2, TIMP-3, and hydroxyproline were measured.
Main Results:
- MMP levels were significantly higher in hernia groups, especially the bilateral hernia group (p < 0.05).
- TIMP levels were significantly lower in the bilateral hernia group (p < 0.05).
- A clear trend of increasing MMPs and decreasing TIMPs was observed from control to indirect, direct, and bilateral hernia groups.
Conclusions:
- Elevated MMPs and decreased TIMPs may contribute to the formation of inguinal hernias.
- Inguinal hernia, particularly bilateral hernia, may reflect a systemic condition involving extracellular matrix imbalance.
- These findings highlight the potential role of MMPs and TIMPs as biomarkers in inguinal hernia development.
