OBJECTIVES: Eosinophilic esophagitis (EoE) is characterized by remissions and relapses. Guidelines defining remission do not exist and therefore remission is inconsistently identified. We sought to define histology remission in EoE.
METHODS: Esophageal biopsies, obtained at the time the validated pediatric EoE symptoms scores v2.0 (PEESS v2.0) questionnaire was completed (N = 42), were scored using the validated EoE Histology Scoring System. An EoE Histology Remission Score (EoEHRS) was constructed and specified that in all esophageal sites sampled the peak eosinophil count was <15 per high power field (HPF); in addition, neither the total grade (severity of pathology) nor stage (extent of pathology) scores could exceed 3 (possible total maximum score for each was 24). Spearman correlation coefficients were generated for histology/symptom correlations; coefficient range 0.31 to 0.50 was considered moderate.
RESULTS: EoE Histology Scoring System composite and individual feature scores from proximal and distal esophageal biopsies correlated moderately with PEESS v2.0 mean scores (0.48-0.36, P < 0.01), and with scores in the dysphagia (0.39-0.30, P ≤ 0.01), pain (0.48-0.34, P ≤ 0.01), and gastroesophageal reflux disease (0.51-0.32, P ≤ 0.01) domains. Biopsies that met full EoEHRS criteria had reduced biomarkers, specifically expression of the mast cell markers CPA3 and tryptase mRNA, and reduced eosinophil peroxidase deposition (P < 0.03), compared to those with nonremission scores. Subjects whose biopsies met EoEHRS remission criteria reported reduced symptoms for all domains except nausea and vomiting (P ≤ 0.01).
CONCLUSIONS: The EoEHRS correlated with reduced biomarkers of disease activity and reduced symptoms, and therefore may be useful to inform clinical care and interstudy comparisons.
