Insights
COVID-19-associated pulmonary aspergillosis (CAPA) is common in critically ill patients. Daily high-dose corticosteroid use predicts CAPA and increases mortality, necessitating avoidance of high-dose steroids post-inflammation and active CAPA surveillance.
Area of Science:
- Infectious Diseases
- Pulmonology
- Critical Care Medicine
Background:
- COVID-19-associated pulmonary aspergillosis (CAPA) risk factors and clinical impact are debated.
- No prior data on CAPA epidemiology in Korea exists.
Purpose of the Study:
- Investigate CAPA epidemiology in Korea.
- Identify CAPA predictors and clinical outcome impacts.
- Evaluate diagnostic efforts for CAPA.
Main Methods:
- Retrospective analysis of severely to critically ill COVID-19 patients (n=218) from January 2020 to May 2021.
- Detailed corticosteroid use (dose, duration) was subcategorized.
- Statistical analysis to identify predictors and mortality impact.
Main Results:
- CAPA diagnosed in 4.6% of hospitalized and 11.2% of ICU patients.
- Independent predictors for CAPA: total cumulative and daily high-dose corticosteroid use.
- Daily high-dose steroid use significantly increased 30-day mortality (HR 5.645).
Conclusions:
- CAPA is prevalent in critically ill COVID-19 patients.
- Daily high-dose corticosteroid use is a key predictor and associated with increased mortality.
- Avoid high-dose corticosteroids post-inflammatory phase and implement active CAPA surveillance in high-risk patients.
Background/Aims:
The risk factors and clinical impacts of coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) remain controversial, and no data have been reported in Korea. This study aimed to investigate the epidemiology and importance of CAPA diagnostic efforts and to identify the predictors of CAPA and the impacts on clinical outcomes.
Methods:
Between January 2020 and May 2021, data of severely to critically ill COVID-19 patients were extracted from seven hospitals of the Catholic Medical Center through a clinical data warehouse. Corticosteroid use was subcategorized into total cumulative dose, early 7-day dose, mean daily dose, and duration of use.
Results:
A total of 2,427 patients were screened, and 218 patients were included. CAPA was diagnosed in 4.6% (10/218) of all hospitalized and 11.2% (10/89) of intensive care unit patients. Total cumulative dose (over 1,000 mg as methylprednisolone) and daily high-dose corticosteroid use (over 60 mg/day) were independent predictors but not early 7-day high-dose corticosteroid use (over 420 mg/week) (odds ratio [OR], 1.731; 95% confidence interval [CI], 0.350 to 8.571) nor prolonged use (OR, 2.794; 95% CI, 0.635 to 13.928). In-hospital overall mortality was 11.9% (26 of 218). CAPA itself did not affect the outcome; rather, daily high-dose steroid use significantly increased the 30-day mortality (hazard ratio, 5.645; 95% CI, 1.225 to 26.091).
Conclusion:
CAPA was not uncommon, especially in critically ill patients. Daily high-dose corticosteroid use was the predictor of CAPA and associated with high mortality rates. High-dose corticosteroids use after early inflammatory phase should be avoided, and active surveillance methods for CAPA are essential for those high-risk patients.
