Chagas Disease Diagnostic Applications: Present Knowledge and Future Steps

Area of Science:

• Tropical medicine
• Parasitology
• Global health

Background:

• Chagas disease, caused by Trypanosoma cruzi, is a significant neglected tropical disease in Latin America with global health implications.
• Limited access to diagnosis and treatment, coupled with low R&D investment, hinders effective management of Chagas disease.
• Current diagnostic methods face limitations regarding reliability, reproducibility, and applicability across diverse patient populations and disease stages.

Purpose of the Study:

• To highlight the urgent need for novel biomarkers in Chagas disease diagnostics.
• To identify biomarkers that ensure accurate and reproducible results across various genetic backgrounds, parasite strains, and clinical presentations.
• To address unmet diagnostic needs, including early congenital transmission detection, treatment monitoring, and disease progression prediction.

Main Methods:

• Review of current knowledge and future directions in Chagas disease diagnostics.
• Exploration of high-throughput methods for biomarker discovery.
• Focus on developing point-of-care diagnostic tools for accessibility.

Main Results:

• Novel biomarkers are expected to overcome limitations of existing diagnostic methods.
• Biomarkers should facilitate early detection, treatment assessment, and disease progression prediction.
• Development of point-of-care diagnostics is essential for underserved populations.

Conclusions:

• Advancements in high-throughput methods offer opportunities for discovering new Chagas disease biomarkers.
• Novel diagnostic tests integrating these biomarkers can significantly improve intervention effectiveness and patient care.
• Developing accessible, reliable diagnostics is paramount for controlling Chagas disease globally.
