Diagnosis and Treatment of Invasive Mold Diseases

Area of Science:

• Mycology
• Infectious Diseases
• Clinical Medicine

Background:

• Invasive fungal diseases (IFDs), particularly invasive mold diseases (IMDs), are increasing in incidence.
• IMDs encompass conditions like aspergillosis, mucormycosis, hyalohyphomycosis, and phaeohyphomycosis.

Purpose of the Study:

• To review the epidemiology, diagnosis, and treatment of invasive mold diseases.
• To provide an overview of current diagnostic criteria and therapeutic strategies for IMDs.

Main Methods:

• Review of epidemiological data on IMDs.
• Discussion of diagnostic methods including histopathology, culture, and clinical criteria (EORTC/MSG definitions).
• Summary of treatment guidelines for specific IMDs.

Main Results:

• Definitive IMD diagnosis relies on histopathology or sterile culture.
• Clinical criteria (EORTC/MSG) aid diagnosis when invasive procedures are not feasible.
• Voriconazole or isavuconazole are first-line for invasive aspergillosis; lipid amphotericin B is an alternative.
• Echinocandins are used for salvage therapy in aspergillosis.
• Invasive mucormycosis requires surgical debridement and antifungal therapy, with lipid amphotericin B as the primary treatment.
• Isavuconazole or posaconazole serve as salvage/step-down therapy for mucormycosis.
• Hyalohyphomycosis and phaeohyphomycosis lack standard therapies, requiring individualized treatment.

Conclusions:

• Accurate diagnosis of IMDs is crucial for effective management.
• Treatment strategies vary significantly based on the specific mold and clinical context.
• Further research is needed for standardized treatment of less common IMDs.
