Insights
COVID-19-associated pulmonary aspergillosis (CAPA) in critically ill patients leads to worse outcomes. Early screening and preventive measures are crucial for high-risk individuals to improve patient survival.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Pulmonology
Background:
- COVID-19-associated pulmonary aspergillosis (CAPA) is a serious complication in critically ill COVID-19 patients.
- Understanding the specific risks and outcomes associated with CAPA is essential for clinical management.
Purpose of the Study:
- To investigate the clinical characteristics, risk factors, and outcomes of CAPA in mechanically ventilated COVID-19 patients.
- To identify patient subgroups at higher risk for developing CAPA.
Main Methods:
- Retrospective cohort study of 396 mechanically ventilated adult COVID-19 patients.
- CAPA diagnosis based on composite clinical criteria.
- Statistical analysis using Fine and Gray competing risks regression and multilevel mixed-effects ordinal logistic regression.
Main Results:
- 39 patients (9.8%) met CAPA criteria.
- CAPA patients had higher rates of pulmonary vascular disease, liver disease, coagulopathy, solid tumors, multiple myeloma, and corticosteroid use.
- CAPA was associated with significantly worse outcomes, including longer time to improvement, faster progression of disease severity, longer mechanical ventilation duration, and extended hospital stays.
Conclusions:
- CAPA is linked to poor clinical outcomes in critically ill COVID-19 patients.
- Prophylactic strategies and vigilant screening are recommended for patients at high risk of developing CAPA.
Background:
Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) occurs in critically ill patients with COVID-19. Risks and outcomes remain poorly understood.
Methods:
A retrospective cohort study of mechanically ventilated adult patients with COVID-19 admitted to 5 Johns Hopkins hospitals was conducted between March and August 2020. CAPA was defined using composite clinical criteria. Fine and Gray competing risks regression was used to analyze clinical outcomes and, multilevel mixed-effects ordinal logistic regression was used to compare longitudinal disease severity scores.
Results:
In the cohort of 396 people, 39 met criteria for CAPA. Patients with CAPA were more likely than those without CAPA to have underlying pulmonary vascular disease (41% vs 21.6%, respectively; P = .01), liver disease (35.9% vs 18.2%; P = .02), coagulopathy (51.3% vs 33.1%; P = .03), solid tumors (25.6% vs 10.9%; P = .02), multiple myeloma (5.1% vs 0.3%; P = .03), and corticosteroid exposure during the index admission (66.7% vs 42.6%; P = .005), and had lower body mass indexes (median, 26.6 vs 29.9 [calculated as weight in kilograms divided by height in meters squared]; P = .04). Patients with CAPA had worse outcomes, as measured by ordinal severity of disease scores, requiring longer time to improvement (adjusted odds ratio, 1.081.091.1; P < .001), and advancing in severity almost twice as quickly (subhazard ratio, 1.31.82.5; P < .001). They were intubated twice as long as those without CAPA (subhazard ratio, 0.40.50.6; P < .001) and had longer hospital stays (median [interquartile range], 41.1 [20.5-72.4) vs 18.5 [10.7-31.8] days; P < .001).
Conclusion:
CAPA is associated with poor outcomes. Attention to preventive measures (screening and/or prophylaxis) is warranted in people with high risk of CAPA.
