Dissociation between symptoms and histological severity in pediatric eosinophilic esophagitis.

ABSTRACT: The relation between patient symptoms and histological severity of eosinophilic esophagitis (EE) is not known. We created a pediatric EE symptom score (PEESS) and compared the results with histological findings in the esophagus.Subjects ages 3 to 18 years with a histological diagnosis of EE or their parent completed a survey rating the frequency and severity of their gastrointestinal symptoms. Scores ranged from 0 to 98. Eosinophil numbers in esophageal biopsy specimens were correlated with the PEESS.A total of 49 subjects completed the PEESS. The symptom score did not correlate with the peak eosinophil count (r = 0.079). Newly diagnosed, untreated EE subjects (N = 15) had a mean score of 24.7 +/- 16.4 with a modest correlation between the PEESS and the number of eosinophils in the distal esophagus (r = 0.37). The mean PEESS score in the 34 treated patients was lower than in untreated patients (15.6 +/- 12.9; P = 0.046). The mean score for treated patients in histological remission was the same as for treated patients with active EE, regardless of treatment type. Abdominal pain was the most frequent and severe symptom reported. Among 20 of the 34 subjects (58.8%) in histological remission, 17 (85%) continued to report symptoms with a mean score of 17.4 +/- 9.9 (range 1-38). Three children with active histological EE (10%) reported no symptoms.Children with untreated EE had a higher PEESS than treated subjects. Symptoms persisted in 85% of EE patients despite histological resolution and 10% with active EE reported no symptoms. Our data indicate a dissociation between symptoms and histology in pediatric EE.

Project description:ObjectivesMast cells (MCs) are increased in eosinophilic esophagitis (EoE). Endoscopic abnormalities, symptoms, and epithelial changes can persist after treatment despite a reduction of esophageal eosinophilia. It is unknown whether this could be due to persistent MC infiltration. We aimed to determine whether patients with histologically inactive (HI) EoE (defined as <15 eosinophils per high-powered field) with persistent symptoms, endoscopic, or epithelial abnormalities after treatment have increased MCs.MethodsSecondary analysis of prospective data from 93 children with EoE undergoing post-treatment endoscopy between 2011 and 2015. Thirty-five non-EoE controls were included. Immunohistochemistry for tryptase, an MC marker, was performed on mid and distal esophageal biopsies. Total and degranulated intraepithelial MCs per high-powered field (MC/hpf) were quantified. Symptoms and endoscopic findings were recorded at time of endoscopy. MC/hpf were compared between HI-EoE and control, and among HI-EoE based on endoscopic and histologic findings, and symptoms. Nine clinical remission (CR) patients were identified, with absence of endoscopic abnormalities and symptoms.ResultsMC/hpf were increased in HI-EoE compared with control (17 ± 11 vs 8 ± 6, P < 0.0). Patients with persistent endoscopic abnormalities had increased total (20 ± 12 vs 13 ± 10, P = 0.001) and degranulated (8 ± 6 vs 5 ± 4, P = 0.002) MC/hpf, with no difference in eosinophils. MC/hpf predicted furrowing (odds ratio = 1.06, P = 0.01) and rings (odds ratio = 1.05, P = 0.03) after controlling for treatment type, proton-pump inhibitor, eosinophils, and duration of therapy. Patients with persistent basal zone hyperplasia and dilated intercellular spaces had increased MC/hpf. Eosinophils were weakly correlated with MC/hpf in the mid (r = 0.30, P < 0.001) and distal (r = 0.29, P < 0.001) esophagus. Clinical remission patients had lower MC/hpf compared with patients with persistent symptoms and/or endoscopic abnormalities.DiscussionMC density is increased in patients with endoscopic and epithelial abnormalities, as well as a few symptoms, despite resolution of esophageal eosinophilia after treatment. This association warrants further study to ascertain whether MCs play an eosinophil independent role in EoE.
