Abstract
AbstractSoluble urokinase plasminogen-activator receptor (suPAR) is a secreted protein associated with inflammation and proven its usefulness in triage/risk stratifications. This prospective study aimed to evaluate the utility of suPAR in comparison to C-reactive protein (CRP) in hospitalized moderate COVID-19 patients.This is a prospective comparative study during second pandemic wave. Serum suPAR level and CRP were measured serially in 31 confirmed COVID-19 hospitalized patients (20 males, 11 females) on day-1 (24-hours of admission), day-3 and day-5 using suPARnostic AUTO flex ELISA and Nephelometry (ThermoFischer) respectively. Schapiro Wilk test verified the data distribution; Wilcoxon signed rank test compared CRP and suPAR between deceased/alive subject and identified link between co-morbidity and COVID-19 severity.In our study, the mean age was 61.8 ranging from 28-82 with 9.7% (n=3/31) mortality rate. Deceased patients showed significant higher suPAR levels correlating with increasing severity from day 1 to 5 (p<0.016-0.006) than CRP (p=0.717). Patients with pre-existing co-morbidities showed significantly elevated suPAR levels on days 1-5, especially those with hypertension (HTN;p<0.03) and chronic kidney disease (CKD;p<0.001).In conclusion, levels of suPAR were higher in deceased patients with severe symptoms of COVID-19 during hospitalization and in patients with pre-existing co-morbid conditions, HTN and CKD. This preliminary study provides evidence suggesting that circulating suPAR can be a potential biomarker to assess the severity of COVID 19 compared to CRP.
