Fig. 1From: Urine Peptidomic and Targeted Plasma Protein Analyses in the Diagnosis and Monitoring of Systemic Juvenile Idiopathic ArthritisSchematic of the experimental design to discover an SJIA systemic flare urine peptide signature. Long-term goals: Aim #1, identification of diagnostic urine peptide profile that distinguishes new onset SJIA patients from other systemic inflammatory states, including Kawasaki disease (KD) and febrile illness (FI). Aim #2, prediction of impending flare during quiescent periods of SJIABack to article page
