Investigating the link between influenza and invasive pulmonary aspergillosis

Unraveling the Pathogenesis of Influenza-associated Aspergillosis: a Single-center, Prospective Cohort Pilot Study

Observational Universitaire Ziekenhuizen KU Leuven · NCT03748069

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.

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.

Who should consider this trial

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.

Not a fit: Patients under 18 years old, pregnant women, or those unable to provide informed consent will not benefit from this study.

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 performed: 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.
