Red Cell Distribution Width Versus Presepsin (Soluble CD14) as a Prognostic Marker in Critically-ill Sepsis Patients

Comparison of Red Cell Distribution Width Versus Presepsin (Soluble CD14) for Prognosis Assessment in Sepsis Patients Admitted to the Intensive Care Unit

Presepsin (soluble CD14 subtype) is a novel marker with growing body of evidence supporting its accuracy and value for the diagnosis of sepsis. Patients with sepsis showed higher Prsepsin levels compared to those with SIRS. In addition the increase in Prsepsin levels correlates well with sepsis severity. Red cell distribution width variations are increased in a variety of medical conditions such as congestive heart failure, acute myocardial infarction, pulmonary embolism, pneumonia, critical illness, and cardiac arrest , and is a predictor of mortality in the general population. we aim to compare between Presepsin (soluble CD14) and RDW as prognostic markers in critically-ill patients with sepsis.
