Pilot study for immunoglobulin E as a prognostic biomarker in coronavirus disease 2019.

Background: Laboratory biomarkers to estimate the severity of coronavirus disease 2019 (COVID-19) are crucial during the pandemic since resource allocation must be carefully planned.

Aims: To evaluate the effects of basal serum total immunoglobulin E (IgE) levels and changes in inflammatory parameters on the clinical progression of patients hospitalised with COVID-19.

Methods: Patients hospitalised with confirmed COVID-19 were included in the study.
