[Increase in the positivity of the galactomannan biomarker during the COVID-19 pandemic in the Fifth Region: Valparaíso]. / Aumento en la positividad del biomarcador galactomanano durante la pandemia de COVID-19 en la Quinta Región: Valparaíso.

ABSTRACT

BACKGROUND: The current pandemic due to SARS-CoV-2 has caused a high burden on health. Cases and series of invasive aspergillosis associated with COVID-19 patients (CAPA) on mechanical ventilation have been described. AIM: To describe the increase in the positivity of the galactomannan (GM) biomarker during the COVID-19 pandemic in the Fifth Region Valparaíso. METHOD: Retrospective descriptive study. The GM results in both broncho-alveolar lavage (BAL) and serum and the BAL cultures that were sent to the Mycology Laboratory of the University of Valparaíso from January to September 2020 were reviewed; then they were compared with the examinations of the same period of 2019. RESULTS: There was a significant increase in GMs carried out in LBA during the pandemic, concentrating mainly between the months of July-September. CONCLUSIONS: There was a significant increase in GM carried out in LBA during the pandemic, concentrating mainly between the months of July-September.
