Biomarker to distinguish AOSD from Sepsis

*AOSD: Adult onset Still’s disease


High sensitivity, specificity and accuracy


The precise cytokine networks in the serum of individuals with AOSD (adult onset Still’s disease) that are associated with its pathogenesis have been unknown.  Serum levels of IL-1β, IL-6 and IL-18 have been reported as useful serum biomarkers for diagnosis and disease evaluation among AOSD patients, but these cytokines are also elevated in other inflammatory diseases including severe infection.
For example, it is reported that serum IL-18 level was elevated in septic patients compared to healthy adults [1].

Technology Overview with Data

Serum FGF-2 (fibroblast growth factor 2), VEGF (vascular endothelial growth factor), GM-CSF (granulocytecolony stimulating factor), IL-17 and IL-18 levels were significantly elevated in the AOSD group versus the sepsis group.  Multivariate classification algorithms followed by a logistic regression analysis revealed that the measurement FGF-2 distinguished AOSD patients from sepsis patients with high accuracy (cut-off value = 35.5 pg/mL, sensitivity 88.3 %, specificity 88.2 %, accuracy 88.3%).
