3.2.2.1. Invasive Aspergillosis: A Clinical Explainer

Описание: This clinical explainer tackles Invasive Aspergillosis (IA), a life-threatening opportunistic fungal infection that poses a significant threat to immunocompromised patients. We provide a comprehensive overview of the disease, outlining the key high-risk groups, including patients with hematological malignancies, stem cell transplants, and severe influenza.

Follow the complete diagnostic pathway, from initial clinical suspicion and high-resolution CT imaging to the critical step of obtaining a bronchoalveolar lavage (BAL) sample. We'll detail why both fungal culture and galactomannan antigen testing are essential for maximizing detection. Learn about the primary pathogens, such as Aspergillus fumigatus, and the growing challenge of antifungal resistance, including the intrinsic resistance of A. terreus and the alarming rise of acquired azole resistance.

We'll also break down the evidence-based treatment strategies, high-risk scenarios like Influenza-Associated Pulmonary Aspergillosis (IAPA), and finish with a clinical challenge to put your knowledge to the test.
