Study of Adhesion Molecules’ (ICAM-1 and VCAM-1) Effects on Immunothrombosis in Severe and Critical COVID-19 Infections in Comparison with Mild Cases

Abstract

Background: The study aimed to evaluate the association among the adhesion molecules (ICAM1 and VCAM-1) with immunothrombosis in severe and critical COVID-19 patients in comparison with mild cases. Materials and Methods: A cross sectional study was conducted. From 1 October 2021 to 30 May 2022, a total of 82 COVID-19 patients were recruited at the hospital in Imam AL-Hussein Medical City/Kerbala, consisting of 44 males and 38 females, and their ages ranged from 25 to 85 years old. All participants were hospitalized after testing positive for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 27 of those were diagnosed with mild COVID-19 and 27 with severe cases, while 28 patients had critical diseases. Results: In mild cases, ICAM-1 adhesion molecule level increased approximately more than four folds over the normal range, and dramatically elevated with COVID-19 progression (p= < 0.001). VCAM-1 level also significantly elevated (p = 0.002), but his elevation was slower than ICAM-1 elevation. Conclusion: There is a more significant correlation among immunothrombosis, cellular adhesion molecules (ICAM-1, VCAM-1) elevation and COVID-19 severity.
