Normal Human Plasma Level of iNOS

The discovery that inducible nitric oxide synthase (iNOS) circulates in people who are developing the sepsis pathology has provided an opportunity to develop a first-in-class diagnostic test for the onset of sepsis. This study is designed to determine the normal human plasma level of circulating iNOS as the initial reference level against which hospitalized patients at risk for the development of sepsis can be compared to ascertain if the patient is at risk for becoming septic based upon an elevated level of plasma iNOS.

Infections in intensive care units (ICUs) and other hospital settings can be caused by different types of organisms, such as bacteria and fungi. Yearly, these infections cause at least 2 million patients in the USA to enter the early stages of the sepsis pathology (pre-sepsis) which will lead to more than 750,000 cases of sepsis that can deteriorate into life-threatening severe sepsis with organ dysfunction and septic shock with multiple organ failure and result in more than 250,000 deaths per year. At present, an accurate clinical lab test to predict the onset of the sepsis pathology does not exist. Thus, there is a large unmet clinical lab need for a test that can aid physicians in assessing the risk their hospitalized patients have for developing the sepsis pathology. A reliable test for predicting very early the onset of sepsis would be a major medical breakthrough. However, a reference level for normal healthy individuals is needed against which plasma levels can be compared for increased (or decreased) levels of iNOS.
