Diagnostic Signatures in Febrile Infants

Sept. 1, 2007 - June 30, 2009

Grant Number
Project Overview
Infants with fever commonly present to the ED. Most febrile infants have non-bacterial infections, but 6-10% have severe bacterial infections. Current diganostic methods are not precise. We propose studying a new method to improve the diagnosis of febrile infants in the PECARN network.
Goals: (1) educate and train a core group of PECARN investigators to conduct research in RNA microarray transcriptional technologies in febrile infants; (2) demonstrate the ability of the PECARN network to obtain high-quality RNA samples used for microarray analysis from febrile infants across multiple participating PECARN EDs; and (3) define the initial diagnostic bacterial biosignatures using RNA microarray transcriptional technologies in young febrile infants presenting to the ED.
