Annexin A1 Levels in SARS-CoV-2 Infection

Adrenal Cortex Hormones, Annexin A1

The present study aims to determine the clinical predictivity value of blood AnxA1 levels in patients with mild and severe/critical pneumonia induced by COVID-19 and to reveal the alterations of blood AnxA1 levels in patients with pneumonia compared to the control group.The present study is a prospective case-control study, and the required ethics approval was obtained from the Ethics Committee of Pamukkale University (Numbered: E-60116787-020-15062). The study was conducted at Ankara Training and Research Hospital between 10.02.2021 and 15.03.2021. All procedures will carried out on patients were in compliance with the Helsinki Declaration.Study groups were established according to the inclusion and exclusion criteria. Patients whose diagnoses were clinically confirmed as COVID-19 infection according to World Health Organization (WHO) guidelines using a positive reverse transcriptase polymerase chain reaction (RT-PCR) test will be included in the study (15). Individuals will be grouped in the moderate COVID-19 disease group (N=42), severe/critical COVID-19 disease group (N=32), and the healthy control group (N=50). Healthy group will be included subjects who had no history or diagnosis of any disease, no infection history within last two weeks, no history of any particular medication, who were admitted to emergency department (ED) with complaints other than infectious issues, and who gave their written consent to participate in the study. Venous blood samples that will be taken when the patients were admitted to ED were withdrawn into a dry test tube that did not contain anti-coagulant and were then centrifugated for 10 minutes at 4000 rpm. Serum samples will be obtained from centrifugation were collected for laboratory analysis. Serum AnxA1 levels were analyzed using a commercially available AnxA1 ELISA Kit (Elabscience, E-EL-H5512, USA), per the manufacturer's protocol.

Control Group: Subjects with no history of a known disease, no infectious symptoms, no drug use, and who provided written consent were included in the study.
