Summary
Fungal biomarkers aid in early detection and monitoring of invasive fungal infections. Tailoring biomarker selection and combining methods improves diagnostic accuracy, especially for high-risk patients.
Area of Science:
- Medical Mycology
- Diagnostic Microbiology
- Infectious Diseases
Background:
- Biomarkers have revolutionized fungal diagnostics, enabling early detection, risk assessment, and treatment monitoring.
- The clinical utility of biomarkers is influenced by sensitivity, specificity, host immune status, and technical standardization.
Purpose of the Study:
- To review antigen- and DNA-based methods for detecting invasive fungal infections.
- To focus on key fungal pathogens: Aspergillus spp., Candida spp., and Mucorales.
Main Methods:
- Review of current literature on antigen- and DNA-based fungal biomarker detection methods.
- Analysis of diagnostic approaches for Aspergillus, Candida, and Mucorales infections.
Main Results:
- Biomarker selection should be individualized based on patient populations, clinical settings, and suspected infections.
- Combining multiple biomarkers can enhance diagnostic accuracy, particularly in immunocompromised or high-risk individuals.
Conclusions:
- Fungal biomarkers are crucial tools supporting diagnosis and guiding treatment decisions for invasive fungal infections.
- Interpretation of biomarker results must integrate clinical context and established guidelines (e.g., EORTC/MSG).
