Association between eosinophil counts and outcomes of severe coronavirus disease 2019 in elderly asthma patients: a prospective cohort study.

ABSTRACT:

Background

Given effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the respiratory system and epidemiological burden of asthma worldwide, coronavirus disease 2019 (COVID-19) in asthma patients caused reasonable concern to be a "dangerous" combination in early pandemic. This is especially pertinent to elderly patients with asthma since older age, diabetes, cardiovascular disease, and hypertension, is associated with more serious complications of COVID-19 and higher mortality. Blood eosinopenia occurs as a part of the total cytopenia at the early stage of severe COVID-19 due to an effect of SARS-CoV-2 virus on the immunity and severe inflammation. Therefore, blood cell count monitoring could be useful for the diagnosis and outcome prediction in COVI
