BACKGROUND: Invasive pulmonary aspergillosis (IPA) is a common cause of fungal infection acquired in intensive care unit (ICU) whose clinical landscape may differ according to SARS-CoV2 infection status.
METHOD: We included all mechanically ventilated patients hospitalized (≥ 48 h) participating in ICU of the REA-REZO network during a 6-year period. Among IPA patients, initial characteristics and outcomes were compared according to COVID-19. Additionally, to account for potential confounders, we performed an inverse probability of treatment weighting (IPTW). Rates of IPA were also compared according to SARS-CoV2 infection. Finally, we investigated risk factors associated with mortality among IPA patients using a Cox model regression.
RESULTS: Among 120 993 patients included during the study period, IPA was diagnosed in 254 patients. COVID-19 Associated Pulmonary Aspergillosis (CAPA) patients were significantly older (median age 69 [62-73] years versus 63 [56-70] years; p < 0.001), less immunosuppressed (23.5% versus 32.4%; p = 0.001) and less severe at baseline (median SAPS II score 45 [35-54] versus 55 [39-65]; p < 0.001) compared to non-COVID-IPA patients. CAPA patients exhibited both a longer duration of mechanical ventilation (16 [9-33] days versus 8 [4-26] days; p = 0.002) and a longer ICU length of stay (LOS) (18 [10-38] days versus 14 [6-30] days, p = 0.015) after IPA diagnosis. However, survival did not differ according to COVID-19 status either in the raw population (log-rank test; p = 0.43) or after weighted Cox regression (HR 0.92 [95%CI 0.61-1.38]; p = 0.69). Incidence of IPA was higher in COVID-19 patients (incidence rate ratio: 8.45 [95%CI 6.59-10.87]; p < 0.001).
CONCLUSION: In this large multicenter cohort, IPA had a similar impact on survival depending on SARS-CoV2 infection status. However, despite lower severity, CAPA patients experienced longer duration of mechanical ventilation and LOS.
