Sepsis Clinical Trial
Official title:
A Cohort Study to Evaluate Biomarkers as Indicator for the Infectious Source of Sepsis Through a Blood Test
A case-control cohort study to develop and validate the performance of a whole blood gene expression test to distinguish sepsis infection from uninfected systemic inflammatory response syndrome cases in symptomatic adults and children without comorbidities.
The purpose of this prospective, non-interventional study is to develop and validate a blood gene expression test for diagnosing the cause of sepsis in adults and children with symptoms of infection. Sepsis affects 31.5 million people globally leading to 5.3 million deaths each year. Sepsis is particularly harmful to immunodeficient patients undergoing cancer therapy with 3.7 percent to 6.4 percent of cancer patients diagnosed with sepsis in the US in their first year after cancer diagnosis. Current tests to diagnose the infectious cause of sepsis rely on blood cultures which takes 24-48 hours to complete; leading to delays in early treatment critical to reduce the risk of developing sepsis shock and possibly death. In addition, around 50 percent of severe sepsis cases are culture negative, confounded acute infections not detected in the blood, by viral infection or uninfected patients exhibiting systemic inflammatory response syndrome (SIRS). Since sepsis often progresses to sepsis shock within 72 hours, suspected sepsis cases are usually immediately treated with antibiotics until results from testing distinguish the cause of symptoms. This leads to the over-use of antibiotics and delays appropriate treatment for those without bacterial infection or un-infected SIRS. A quick and accurate diagnostic blood test may enable early discrimination of the cause of sepsis resulting in faster more appropriate treatments and reduced sepsis complications and death. The study will collect blood samples from participants presenting symptoms of acute infection, without co-morbidities and follow symptom severity and mortality for 28 days. ;
