Comparison of the Existence of Mycobacterium leprae on the Ground with Polymerase Chain Reaction Techniques in Residential Areas Former Leprosy with Leprosy Sufferers on Sicanang Island Medan Belawan

Introduction

Leprosy, a chronic bacterial infection caused by Mycobacterium leprae, remains a significant health concern in many countries, including Indonesia. Despite the implementation of the multi-treatment therapy program for over 20 years, efforts to control and eliminate leprosy continue to face challenges. One of the reasons for this is the presence of various environmental sources of leprosy transmission, such as soil, plants, water, arthropods, and armadillo animals. This study aims to investigate the difference in the existence of M. Leprae in the soil of residential areas former leprosy sufferers and settlements without leprosy sufferers on Sicanang Island, Medan Belawan, using the Polymerase Chain Reaction (PCR) technique.

Background

Leprosy is a complex disease that affects not only the individual but also the community. The transmission of leprosy is believed to occur through direct contact with an infected person, but environmental sources, such as soil, can also play a role in facilitating transmission. The presence of M. Leprae in the environment has been a concern for health authorities, as it can contribute to the spread of the disease. However, the role of the environment in leprosy transmission is not well understood, and more research is needed to determine the significance of environmental sources.

Methodology

This study involved the collection of 30 soil samples from two different locations: 15 samples from residential areas former leprosy sufferers and 15 samples from settlements without leprosy sufferers. The samples were then subjected to DNA extraction, PCR examination using Nested Primary Specific Primary (LPR-LPF, LP3-LP4) for M. Leprae, and electrophoresis for results analysis. The PCR technique is a sensitive method for detecting the presence of M. Leprae in soil samples.

Results

The results of this study showed that M. Leprae was not found in either the residential land former leprosy sufferers or the settlements without leprosy sufferers. This finding is significant, as it suggests that the soil does not play a direct role in facilitating M. leprae transmission to humans.

Discussion

The absence of M. Leprae in the soil in both settlements provides important insights about the role of the land as a potential source of leprosy transmission. In general, there is an assumption that the environment, including the land of residence, can contribute to the transmission of leprosy. However, the findings of this study indicate that the soil does not play a direct role in facilitating M. leprae transmission to humans.

This finding is very relevant in the context of leprosy control programs that have been carried out in Indonesia. With the evidence that the soil is not a source of transmission, the focus of control can be more directed at the handling of individuals and preventing transmission between humans, rather than worrying about environmental factors that were previously considered risky.

In addition, the lack of M. Leprae in the soil sample also shows the success of the Multidrug Therapy (MDT) treatment program that has been implemented, which is likely to reduce the burden of infection in the community. This analysis provides new hopes in efforts to control leprosy and provide guidance for further research in the field of leprosy epidemiology, especially about risk factors and more appropriate transmission mechanisms.

Conclusion

Overall, this research sharpens our understanding of leprosy epidemiology and strengthens the steps in fighting a long-time global health problem. This finding is important not only for people who live around former leprosy settlements, but also for researchers and health policy makers in formulating more effective disease control strategies.

Recommendations

Based on the findings of this study, the following recommendations can be made:

Focus on individual-level interventions: The results of this study suggest that the focus of leprosy control programs should be on individual-level interventions, such as early detection and treatment, rather than on environmental factors.
Strengthen MDT treatment program: The success of the MDT treatment program in reducing the burden of infection in the community should be continued and strengthened.
Further research on leprosy epidemiology: Further research is needed to determine the significance of environmental sources in leprosy transmission and to identify risk factors and more appropriate transmission mechanisms.

Limitations

This study has several limitations, including:

Small sample size: The sample size of this study was small, which may limit the generalizability of the findings.
Limited geographic scope: The study was conducted in a specific geographic area, which may not be representative of other areas.
Limited duration: The study was conducted over a short period, which may not capture the full range of environmental factors that contribute to leprosy transmission.

Future Directions

Future studies should aim to:

Investigate the role of environmental sources in leprosy transmission: Further research is needed to determine the significance of environmental sources in leprosy transmission and to identify risk factors and more appropriate transmission mechanisms.
Develop more effective disease control strategies: The findings of this study suggest that more effective disease control strategies should be developed, focusing on individual-level interventions and strengthening the MDT treatment program.
Conduct further research on leprosy epidemiology: Further research is needed to determine the significance of environmental sources in leprosy transmission and to identify risk factors and more appropriate transmission mechanisms.
