Investigating the link between influenza and invasive pulmonary aspergillosis
Official title: Unraveling the Pathogenesis of Influenza-associated Aspergillosis: a Single-center, Prospective Cohort Pilot Study
Run by Universitaire Ziekenhuizen KU Leuven · NCT03748069 · Data updated 2026-11-12
This study looks at how having the flu affects patients with severe pneumonia in the ICU and whether it leads to more serious lung infections.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older admitted to the ICU with respiratory distress due to microbiologically confirmed influenza or community-acquired pneumonia.
✕Probably not a fit
Patients under 18 years old, pregnant women, or those unable to provide informed consent will not benefit from this study.

What this trial studies
This observational trial aims to explore the immunological and pathological characteristics of patients with severe community-acquired pneumonia in the ICU, comparing those with influenza to those without. The study will include all consecutive patients aged 18 or older who are admitted to the ICU with respiratory distress and a microbiologically confirmed diagnosis of either influenza or non-influenza pneumonia. The findings will be correlated with the occurrence of secondary invasive pulmonary aspergillosis infections, providing insights into the impact of influenza on pneumonia outcomes.
Why it matters
Potential benefit: If successful, this study could enhance understanding of the relationship between influenza and secondary infections, potentially improving treatment strategies for affected patients.
How similar studies have gone: While this study focuses on a specific correlation, similar investigations into the effects of viral infections on secondary bacterial or fungal infections have shown promising results.
