The executive summary of the guideline aims to provide the most relevant recommendations on the diagnosis and treatment of invasive pulmonary aspergillosis in critically ill patients in the intensive care unit. The guideline’s work included a systematic literature search, selection and assessment of the data relevant to the issues identified. Key questions included the areas of epidemiology, risk factors, diagnostics, and therapy. They were discussed analogous to a PICO scheme within the guideline committee, with subsequent working groups proposing recommendations for specific key questions, which were then again discussed and finalized by the entire guideline committee. In addition to the classic risk factors (persistent neutropenia, allogeneic stem cell transplantation, congenital or acquired immunodeficiency, etc. ), decompensated liver cirrhosis, COPD, solid tumours and viral pneumonia (influenza, COVID-19) have been established as risk factors for critically ill patients in need of intensive care. If there is no adequate improvement or even further clinical deterioration of the respiratory status in critically ill patients, the presence of IPA should be considered and appropriate diagnostic tests should be initiated. Diagnostics should include a CT scan of the chest and a broncho-alveolar lavage with culture for moulds, testing for galactomannan and PCR. Isavuconazole and voriconazole are recommended as first-line treatment, liposomal amphotericin B as an alternative, with posaconazole (PCZ) or the echinocandins (as an add-on to azole or polyene treatment) being additional options for salvage treatment. Invasive aspergillosis in critically ill patients represents a diagnostic and therapeutic challenge. If indicated, invasive aspergillosis should be considered and appropriate diagnostic tests initiated. Isavuconazole and voriconazole are recommended as first-line treatment, liposomal amphotericin B as an alternative.
