Markers of Severity (CD177,S100A8 &S100A12) in Sever Acute Respiratory Syndrome Coronavirus 2(SARS-COV-2) Patients

Patients infected with covid-19 have a series of clinical manifestations, including fever, cough, myalgia or fatigue, dyspnea, even acute respiratory distress syndrome (ARDS), acute cardiac injury and secondary infection, and a lot of sever patients had to been admitted to the intensive care unit (ICU) One of the hallmark of COVID 19 is the cytokine storm that provokes primarily pneumonia followed by systemic inflammation. besides the positive viral nucleic acid analysis and the representative pulmonary CT findings (bilateral distribution of patchy shadows and ground glass opacity), most individual patients showed the changes in several immunological and biological markers . CD177 which is one of the most clinically important neutrophil alloantigen because: i) it is a neutrophil-specific marker representative of neutrophil activation, ii) it was the most highly differentiated expressed gene in patients, and iii) the protein can be measured in the serum, making its use as a marker clinically applicable. It is expressed on neutrophils, neutrophilic metamyelocytes, and myelocytes . Given the contribution of the neutrophil activation pathway in the clustering of COVID-19 patients, neutrophil-activation features that could act as possible reliable markers of disease evolution.
