Key clinical point: Children with eosinophilic esophagitis (EoE) have distinct salivary immunoinflammatory protein profiles compared with those without EoE, highlighting the diagnostic potential of salivary proteins in pediatric EoE.
Major finding: Children with EoE were distinguished from those without EoE through a panel of 10 proteins (higher expression levels of C-C motif chemokine-3, macrophage metalloelastase, granulocyte colony-stimulating factor-3, interleukin [IL]-15, pro-transforming growth factor alpha, and oncostatin-M and lower expression levels of IL-18, C-C motif chemokine-2, interstitial collagenase, and macrophage colony-stimulating factor-1), with an accuracy of 0.95 validated through the Least Absolute Shrinkage and Selection Operator regression.
Study details: This cross-sectional study analyzed the saliva samples collected from 40 children aged 6-18 years with (n = 23) or without EoE (n = 17) immediately before their scheduled esophagogastroduodenoscopy with biopsies.
