A strategy for managing fungal infections in haematopoietic stem cell transplantation

Area of Science:

• Hematology
• Infectious Diseases
• Mycology

Background:

• Allogeneic hematopoietic stem cell transplantation (HSCT) is increasingly used for various indications.
• This leads to a higher number of patients at risk for invasive fungal infectious diseases (IFID), especially candidiasis and aspergillosis.
• Improved understanding of risk factors and enhanced diagnostic methods are crucial for managing IFID in this population.

Purpose of the Study:

• To outline the current landscape of invasive fungal infections in allogeneic HSCT recipients.
• To highlight advancements in diagnostics and therapeutic options for IFID.
• To propose a framework for developing effective and cost-efficient IFID management strategies.

Main Methods:

• Review of current literature and international consensus on IFID diagnosis.
• Evaluation of available and emerging antifungal agents.
• Assessment of diagnostic criteria including host factors, clinical evidence, and mycological results.

Main Results:

• International agreement exists on a three-element approach for IFID definition (host, clinical, mycological).
• Imaging and indirect tests like antigen detection are accepted mycological evidence.
• A growing arsenal of antifungal drugs enables selective prophylaxis, preemptive, and specific therapies with flexible administration.

Conclusions:

• The necessary components are available to design and test effective and economically sound strategies for IFID management in HSCT patients.
• Standardized diagnostic criteria and improved therapeutic options pave the way for better patient outcomes.
• Future efforts should focus on implementing and evaluating integrated IFID management plans.
