How Esophageal Dilatation Affects Symptoms and Inflammation in Eosinophilic Esophagitis

E Safroneeva et al. Clin Gastroenterol Hepatol 2022; 20: 766-775. Long-Lasting Dissociation of Esophageal Eosinophilia and Symptoms After Dilation in Adults With Eosinophilic Esophagitis

100 adults enrolled in a multisite prospective observational study in which 55 underwent dilatation. Key findings:

  • In nondilated patients, the association between eos/hpf and symptoms was moderate (ρ = 0.49; P < .001) based on the symptom-based EoE activity index (EEsAI); for a 10-eos/hpf increase, the predicted EEsAI increased by 2.69 (P = .002)
  • In patients dilated 1 or less and more than 1 year before index endoscopy, this association was abolished (ρ = -0.38; P = .157 for ≤1 y and ρ = 0.02; P = .883 >1 y)

Limitations: sample size (only 25% subset of total cohort due to missing data), cross-sectional study design

My take: This finding is a double-edge sword. The good part is that dilatation improves dysphagia despite ongoing inflammation which may be refractory to current medical treatments. The bad part is this dissociation in symptoms makes it less likely for patients to be adherent to therapy.
