RESUMEN
BACKGROUND: The presentation of eosinophilic esophagitis (EoE) is heterogeneous, but trends over time are not known. AIM: To determine whether clinical and endoscopic phenotypes at EoE diagnosis have changed over the past 2 decades. METHODS: In this retrospective cohort study, adults and children with newly diagnosed EoE were phenotyped as follows: (1) inflammatory vs fibrostenotic vs mixed on endoscopy; (2) atopic vs non-atopic; (3) age at symptom onset; (4) age at diagnosis; (5) presence of autoimmune or connective tissue disease; and (6) responsive to steroids. The prevalence of different phenotypes was categorized by 5-year intervals. Multivariate analysis was performed to assess for changes in patient features over time. RESULTS: Of 1187 EoE patients, age at diagnosis increased over time (from 22.0 years in 2002-2006 to 31.8 years in 2017-2021; p < 0.001) as did the frequency of dysphagia (67% to 92%; p < 0.001). Endoscopic phenotypes were increasingly mixed (26% vs 68%; p < 0.001) and an increasing proportion of patients had later onset of EoE. However, there were no significant trends for concomitant autoimmune/connective tissue disease or steroid responder phenotypes. On multivariate analysis, after accounting for age, dysphagia, and food impaction, the increase in the mixed endoscopic phenotype persisted (aOR 1.51 per each 5-year interval, 95% CI 1.31-1.73). CONCLUSION: EoE phenotypes have changed over the past two decades, with increasing age at diagnosis and age at symptom onset. The mixed endoscopic phenotype also increased, even after controlling for age and symptomatology. Whether this reflects changes in provider recognition or disease pathophysiology is yet to be elucidated.

OBJECTIVES: Feeding tubes can provide a temporary or long-term solution for nutritional therapy. Little is known regarding the use of feeding tubes in patients with eosinophilic esophagitis (EoE). We sought to describe the characteristics and outcomes in EoE patients requiring tube feeding. METHODS: This was a retrospective cohort study of EoE patients at a large tertiary care health system. Demographics, clinical characteristics, and endoscopic findings were extracted from medical records, and patients who had a feeding tube were identified. Patients with and without a feeding tube were compared. Details about the tube, complications, and treatment were extracted. Growth, global symptomatic, endoscopic, and histopathologic (<15 eos/hpf) responses were compared before and after the initiation of feeding tube therapy. RESULTS: We identified 39 of 1216 EoE patients who had a feeding tube (3%). Feeding tube patients were younger (mean age 6.3 years), reported more vomiting, and had a lower total endoscopic reference score than non-feeding tube patients ( P < 0.01 for all). Tubes were used for therapy for an average of 6.8 years, with most patients (95%) receiving both pharmacologic and formula treatment for EoE. An emergency department visit for a tube complication was required in 26%. Tube feeding improved body mass index z score ( P < 0.01), symptomatic response (42%), endoscopic response (53%), and histologic response (71%). CONCLUSIONS: Among EoE patients, only a small subset required a feeding tube and predominantly were young children with failure to thrive. Feeding tubes significantly improved growth and, when used in combination with other treatments, led to reduced esophageal eosinophilic inflammation.

BACKGROUND AND AIMS: Some eosinophilic esophagitis (EoE) patients can have a decline in eosinophil count after proton pump inhibitor (PPI) treatment without achieving histologic response, but little is known about this group. We aimed to determine the effect of PPIs on reducing esophageal eosinophilia in patients deemed non-responsive to PPI therapy. METHODS: We analyzed prospectively collected cohort data from newly diagnosed adults with EoE who were histologic non-responders (≥15 eos/hpf) to PPI-only therapy. Symptoms, endoscopic histologic features were assessed before and after PPI. Pre- and post-PPI treatment esophageal biopsies were read by pathologists to determine peak eosinophil counts and other histologic findings. RESULTS: Of 125 patients, peak eosinophil counts were 102.1 ± 69.8 and 102.9 ± 101.1 (p=0.93) before and after PPI treatment, respectively, but lamina propria fibrosis decreased from 97% to 41% (p<0.001). Heartburn frequency also decreased (19% to 11%; p=0.006), though endoscopic findings did not change. There were 75 patients (60%) who had some decrease in eosinophil counts, with 30 patients (24%) having ≥50% decrease in counts. When comparing the ≥50% and <50% decrease groups, differences in endoscopic features were identified, but the ≥50% group had improvement in eosinophil degranulation, microabscesses, spongiosis, and basal cell hyperplasia. CONCLUSION: Peak eosinophil counts did not decrease overall after PPI treatment, but symptoms of heartburn improved. Approximately a quarter had ≥50% decrease in eosinophil counts, with associated decreases in other histologic findings. Further research may consider what role PPIs have in this subset of non-responders or in combination therapies.
