Fungal infections after hematopoietic stem cell transplantation

Area of Science:

• Infectious Diseases
• Hematology
• Transplantation Medicine

Background:

• Invasive fungal infections (IFIs) are a major cause of morbidity and mortality in hematopoietic stem cell transplantation (HSCT) recipients.
• Despite advances in prophylaxis and transplantation, IFIs remain a significant challenge due to diagnostic difficulties and high attributable mortality.

Purpose of the Study:

• To review recent advancements in the diagnosis and management of IFIs in HSCT recipients.
• To highlight the importance of optimizing diagnostic, prophylactic, and therapeutic approaches for individual patient risk profiles.

Main Methods:

• Review of current literature on IFIs in HSCT.
• Incorporation of advanced diagnostic tools like high-resolution computed tomography (HRCT) and non-culture-based assays (galactomannan, (1,3)-beta-D-glucan).
• Evaluation of newer antifungal agents for prophylaxis and salvage therapy.

Main Results:

• Epidemiology of IFIs has evolved with changes in transplantation procedures and preventative strategies.
• Diagnostic difficulty remains a key factor in delayed treatment initiation and high mortality.
• Advanced imaging and biomarker tests are integrated into clinical practice for early detection.

Conclusions:

• Optimizing diagnostic strategies, including advanced imaging and biomarkers, is essential for timely IFI management.
• Prophylactic and therapeutic approaches, including newer antifungal agents, require careful consideration based on patient risk.
• A personalized approach to diagnosis, prophylaxis, and treatment is critical for improving clinical outcomes in HSCT recipients with IFIs.
