The Relationship between TYP-1 Expression and MMP-9 Expression in Cholesteatoma Patients: A Study at H. Adam Malik Hospital Medan

Introduction

Cholesteatoma is a type of non-neoplastic lesion that occurs due to the exfoliation or desquamation of squamous epithelium in the middle ear. This condition can lead to the destruction of hard and soft tissues around it, causing significant damage to the affected individual. Recent research has shown that variations in cellular systems play a crucial role in the production of metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs), which contribute to the pathophysiology of cholesteatoma, particularly in the process of bone erosion.

The Importance of Understanding Cholesteatoma

Cholesteatoma is a common complication of chronic suppurative otitis media (CSOM), and its management is often challenging due to the complex pathophysiological mechanisms involved. The destruction of bone and soft tissues caused by cholesteatoma can lead to significant morbidity and mortality, making it essential to understand the underlying mechanisms of this condition. Recent studies have highlighted the role of MMPs and TIMPs in the pathophysiology of cholesteatoma, and this study aims to investigate the relationship between TYP-1 expression and MMP-9 expression in cholesteatoma patients.

Research Objectives

This study aims to:

Identify the relationship between TYP-1 expressions and MMP-9 expressions in cholesteatoma patients.
Evaluate the effect of MMP-9 expression on the degree of bone destruction in cholesteatoma patients.

Methodology

This study employed an analytic cross-sectional design, where researchers conducted immunohistochemical examinations of 40 samples of cholesteatoma patients to assess the level of TYP-1 and MMP-9 expression and their relationship with the degree of bone destruction.

Results

The results of this study showed that:

The most proportion of TYP-1 expression was in the non-overexpression group, which was 37 people (92.5%).
The most proportion of MMP-9 expression was in the overexpression category, which was 34 people (85%).
The most common degree of bone destruction found was moderate, which was recorded in 19 patients (47.5%).

Conclusion

Statistical analysis showed that there was no significant relationship between TYP-1 expressions and MMP-9 (p = 0.096). However, there was a significant relationship between MMP-9 expression and the degree of bone destruction in cholesteatoma patients (p = 0.000). These results indicate that although TYP-1 is not directly related to MMP-9, the expression of MMP-9 has an important role in the process of bone destruction that occurs in cholesteatoma.

Discussion

The importance of this study lies in a better understanding of the pathophysiological mechanism that underlies cholesteatoma. MMP-9, as an enzyme that plays a role in the degradation of extracellular matrix, can accelerate the process of bone erosion. Conversely, TYP-1 functions as an inhibitor of MMP activity, which should protect tissue from damage. However, in this study, TYP-1 does not show a significant relationship with MMP-9, which can be caused by other factors that affect the balance between MMP and TIMP activity in the context of cholesteatoma.

Implications of the Study

This study has several implications for the management of cholesteatoma. Firstly, it highlights the importance of understanding the pathophysiological mechanisms underlying cholesteatoma, particularly the role of MMP-9 in bone destruction. Secondly, it suggests that TYP-1 may not be a reliable marker for predicting the degree of bone destruction in cholesteatoma patients. Finally, it emphasizes the need for further research to explore other aspects that may contribute to the process of bone destruction, such as genetic factors, the environment, and immune systems.

Future Directions

Further research is needed to explore other aspects that may contribute to the process of bone destruction, such as genetic factors, the environment, and immune systems. A deeper understanding of this interaction can help in the development of more effective therapy to deal with cholesteatoma complications in CSOM, as well as in an effort to prevent further damage to the tissue involved.

Limitations of the Study

This study has several limitations. Firstly, the sample size was relatively small, which may limit the generalizability of the results. Secondly, the study only investigated the relationship between TYP-1 expression and MMP-9 expression, and did not explore other factors that may contribute to the process of bone destruction. Finally, the study was conducted in a single hospital, which may limit the representativeness of the results.

Conclusion

In conclusion, this study highlights the importance of understanding the pathophysiological mechanisms underlying cholesteatoma, particularly the role of MMP-9 in bone destruction. The results of this study suggest that MMP-9 expression is a significant predictor of the degree of bone destruction in cholesteatoma patients, and that TYP-1 may not be a reliable marker for predicting the degree of bone destruction. Further research is needed to explore other aspects that may contribute to the process of bone destruction, and to develop more effective therapy to deal with cholesteatoma complications in CSOM.
