Diagnostic for Sepsis

摘要

A method of diagnosing severe sepsis prior to definitive clinical diagnosis. A pattern of gene expression that correlates strongly with a future diagnosis of severe sepsis and organ failure was identified in patients who had their blood drawn at first clinical presentation. The methods comprise identifying a pattern of two or more polynucleotides, whereby the altered expression of these polynucleotides correlates with prospective and actual sepsis. Also methods of identifying agents for treating sepsis based on the characteristics of this gene expression pattern are provided.

主权项

1. A method for diagnosing sepsis in a subject, comprising determining in a biological sample obtained from the subject a level of expression for each of a plurality of Endotoxin Tolerance Signature genes to provide a sample gene signature, and comparing the sample gene signature with a reference gene signature, wherein the reference gene signature represents a standard level of expression of each of the plurality of genes; wherein a difference between the sample gene signature and the reference gene signature indicates that the subject has sepsis.
