Emerging issues with diagnosis and management of fungal infections in solid organ transplant recipients

Area of Science:

• Medical Mycology
• Transplant Infectious Diseases
• Antimicrobial Stewardship

Background:

• Invasive fungal infections (IFIs) pose a significant threat to solid organ transplant (SOT) recipients, risking graft loss and mortality.
• Current management involves a low threshold for antifungal prophylaxis and empiric therapy, leading to increased costs, toxicities, and resistance.
• Rational use of antifungal agents is essential in this vulnerable population.

Purpose of the Study:

• To review recent advancements in diagnosing and managing IFIs in SOT recipients.
• To emphasize the critical role of early diagnostic tools and judicious antifungal stewardship.
• To highlight the need for validation of novel diagnostic methods in SOT patients.

Main Methods:

• Review of recent literature on IFI diagnosis and management in SOT recipients.
• Conceptual summary of emerging diagnostic technologies.
• Discussion of the impact of infectious diseases consultation.

Main Results:

• Novel diagnostic approaches like fungal biomarkers, molecular methods, and breath volatile metabolite detection offer faster diagnosis.
• These tools can facilitate early, appropriate treatment and potential de-escalation of antifungal therapy.
• Infectious diseases consultation optimizes antifungal treatment, manages toxicities, and addresses drug interactions.

Conclusions:

• Early diagnosis and appropriate management are vital for improving outcomes in SOT recipients with IFIs.
• Novel diagnostic modalities require specific validation in the SOT population.
• Optimized antifungal stewardship, supported by diagnostics and expert consultation, is key to combating IFIs and resistance.
