Summary

Invasive pulmonary aspergillosis (IPA) has traditionally been considered a disease of the severely immunocompromised host. However, emerging evidence over the past decade has identified severe influenza as a significant risk factor for IPA, termed influenza-associated pulmonary aspergillosis (IAPA) . The reported incidence of IAPA in ICU patients ranges from 11% to 32%, with associated mortality exceeding 50% in some cohorts.

The pathophysiology of IAPA is thought to involve influenza virus-induced damage to the respiratory epithelium, which impairs mucociliary clearance and disrupts local immune defenses, thereby facilitating invasion by aspergillus species. Studies from recent influenza seasons report IAPA incidences ranging from 16% to 23% in critically ill patients, with associated mortality rates soaring to over 50% . This mortality is substantially higher than that observed in influenza patients without IPA, underscoring the severity of this co-infection.

Despite this recognized threat, significant knowledge gaps remain. Existing studies on IAPA are predominantly single-center or include a limited number of patients, with considerable heterogeneity in their outcomes, constraining the generalizability of their findings . A comprehensive understanding of the specific risk factors that predispose influenza patients to IPA is crucial for early identification and intervention. Furthermore, the clinical course and determinants of mortality specifically within the IAPA population are not yet fully elucidated.

Therefore, we We conducted a retrospective, multicenter cohort study across 20 ICUs in China. Patients were categorized into IPA and non-IPA groups based on FUNDICU diagnostic criteria (clinical, radiological, and mycological evidence) to describe the risk factors, clinical characteristics and outcomes of critically ill patients with IAPA.
