[COVID-19-associated pulmonary aspergillosis in critically ill patients: experience of a Chilean public hospital].

BACKGROUND

Aspergillus spp. fungal coinfections have been described in critically ill COVID-19 patients.

AIM: To describe the clinical characteristics, diagnosis, treatment and evolution of patients with acute respiratory distress syndrome with COVID-19, who present with COVID-19 associated pulmonary aspergillosis (CAPA) in a single public hospital.

METHODS

Retrospective review of clinical records during 12 months in patients diagnosed with CAPA by cultures of respiratory samples or determination of galactomannan (GM).

RESULTS

Probable CAPA was diagnosed in 11 patients (average APACHE II score of 11.7). Respiratory samples were obtained in 73% of cases by bronchoalveolar lavage and in 27% by tracheal aspirate. A. fumigatus was isolated in 4 cultures, A. niger, A. terreus and Aspergillus spp on one occasion each and the cultures were negative in 4 samples. Respiratory sample GM was performed in 7 patients, median: 3.6 (IQR: 1.71 - 4.4). In 10 patients, serum GM was performed, median: 0.5 (IQR: 0.265 - 0.9 75) with 50% of them > 0.5. Two patients showed classic findings suggestive of CAPA on computed tomography. All received antifungal therapy with voriconazole, mean time 14 days. Four patients died.

CONCLUSIONS

The presence of CAPA should be a diagnosis to be considered in critically ill COVID-19 patients.
