Could eosinophil chemotactic factor (CCL11) be a useful biomarker of Covid-19?

Abstract

Background/Aim: Differentiating COVID-19 positive patients from negative ones with similar symptoms and predicting the course of disease are major problems in COVID-19. For this purpose, we investigated the performance of Eosinophil Chemotactic Factor (CCL11) in COVID-19 and compared complete blood count parameters and indexes. Methods: In this retrospective case-control study, ECF/CCL11 values, as well as the clinical, laboratory and radiological data of thirty patients who were diagnosed with Covid-19 between 15 March-15 June 2020 were compared with those of thirty healthy controls. Results: Both patients and controls included 10 (33.30%) females and 20 (66.60%) males with a mean age of 57.2 (15.46) and 60.07 (20.59) years, respectively. Eosinophil counts of the patients on admission (EO1) were significantly lower than those of the controls and one-week later EO2 levels (P
