Invasive aspergillosis: A comprehensive review

Invasive aspergillosis (IA) is a severe fungal infection caused by Aspergillus species, particularly Aspergillus fumigatus, although new species, sometimes resistant to antifungals are becoming more common. IA predominantly affects immunocompromised patients, such as those with haematological malignancies, solid organ transplant recipients, and critically ill patients. However, new at-risk populations have emerged in recent years, such as IA associated with severe viral infections. Advanced diagnostic methods are crucial, especially considering the rising concern of antifungal resistance. Early detection is critical for successful treatment, typically involving antifungal medications like voriconazole or amphotericin B, but new antifungals are arriving to complete the therapeutic strategies. Despite advancements, mortality rates remain high, underscoring the importance of timely interventions and ongoing research. Healthcare providers should maintain a high index of suspicion, especially in immunocompromised patients and other new risk factors that are arising, to promptly diagnose and manage invasive aspergillosis.
