S1857 The Correlation Between Eosinophilic Esophagitis and Aeroallergens

for each feature). EE patients also had significantly higher epithelial scores (mean of 7.33 as compared to 0.52 in GERD, p<0.001) and higher LP maximum scores (mean 4.5 versus 1 in GERD, p<0.001). Epithelial histologic features correlated well with endoscopic features of furrows/thickening, plaques, and pallor (r=0.62-0.82, p<0.001 for each) while LP scores correlated best with the endoscopic feature of thickening/furrows (r=0.64, p=0.002). Symptom complaints of dysphagia + anorexia/early satiety correlated best with epithelial scores (r=0.32, p=0.01); dysphagia correlated best with LP scores (r=0.45, p=0.04). None of the other symptoms assessed correlated with histologic or endoscopic findings. Conclusion: EE patients have significantly more severe endoscopic and histologic changes as compared with GERD patients. The objective endoscopic and epithelial/LP histologic features correlate well with one another. However, of subjective complaints, only dysphagia and anorexia/early satiety correlate with histologic and endoscopic findings.
