Impedance Measurements with Eosinophilic Esophagitis

Briefly noted: MA Lowry et al. JPGN 2018; 67: 198-203.  This study showed that active eosinophilic esophagitis (EoE) was associated with much lower impedance values that inactive EoE, NERD, and controls.  At 2, 5 and 10 cm above the squamo-columnar junction, median values of impedance with active EoE were 1069, 1368, and 1707 respectively.  In comparison, inactive EoE had median values were 3663, 3657, and 4494, respectively.  My take: Since impedance was also performed during endoscopy with sedation, this does not represent a significant advance in current management.
