Summary
Early detection of Mycobacterium leprae (M. leprae) infection is crucial for reducing leprosy transmission. Identifying immune and genetic biomarkers can lead to diagnostic tests for asymptomatic cases, aiding early intervention and preventing nerve damage.
Area of Science:
- Infectious Diseases
- Immunology
- Genetics
Background:
- Leprosy remains a global health issue due to persistent Mycobacterium leprae (M. leprae) transmission.
- Current diagnostic methods rely on clinical signs, lacking tests for asymptomatic M. leprae infection or predicting disease progression.
Purpose of the Study:
- To review the challenges in discovering biomarkers for M. leprae infection.
- To discuss the implementation of these biomarkers in field-friendly diagnostic tests.
Main Methods:
- Identification of immunological or genetic biomarkers for disease development and leprosy reactions.
- Review of tests detecting biomarkers for cellular and humoral immunity.
Main Results:
- Biomarker discovery for M. leprae infection faces significant challenges.
- Simultaneous detection of cellular and humoral immunity biomarkers shows promise for diagnosing leprosy outcomes.
Conclusions:
- Longitudinal studies comparing immune and genetic biomarkers are essential in endemic areas.
- Investigating co-infections' impact on biomarker profiles is necessary.
- Biomarker-based diagnostic tests can significantly aid early leprosy detection and reduce nerve damage.
