A significant gap in our understanding of eosinophilic esophagitis (EoE) lies in how environmental factors, such as allergens or food, influence the response to proton pump inhibitor (PPI) therapy. While PPI achieve histologic remission in approximately 50% of patients, the response in the remaining 50% remains unclear. Addressing this, Muftah and colleagues conducted a study to evaluate the relationship between environmental and food allergies and PPI response in newly diagnosed EoE patients.
Between 2012 and 2016, adult patients newly diagnosed with EoE were tested for environmental and food allergies. Following diagnosis, patients participated in an 8-week trial of twice-daily PPI therapy. The treatment's effectiveness was assessed through repeated upper endoscopies with esophageal biopsies.
The study's primary outcome was the histologic remission of EoE, defined as a decrease in eosinophils to < 15 eosinophils/high-powered field (eos/hpf) in all esophageal biopsy samples during repeat endoscopy. Out of 61 patients, 21 achieved histologic remission, while 40 were classified as having PPI-nonresponding EoE. Among PPI-nonresponding EoE patients, positive food allergen testing was significantly more prevalent compared with PPI-responding EoE patients (82.5% vs 42.9%; P = .0003). Additionally, patients with >10 positive environmental allergen tests were significantly less likely to be PPI-responding EoE patients than those with <10 positive results (21% vs 53.9%; P = .03). A similar trend was observed in patients with >5 positive environmental allergens.
This study is not without limitations. It may exhibit a selection bias toward more severe cases and has a relatively small sample size, affecting its statistical power and generalizability.
This research supports the idea of more tailored management for EoE patients, focusing on their allergen profile, potentially leading to more effective treatment strategies and reducing unnecessary PPI trials. The statistically significant results pave the way for further research, providing an additional tool to predict PPI responsiveness and prevent delays in achieving remission.
Clinicians should consider patient characteristics, particularly positive food allergen tests, that might affect treatment response. More studies are needed, however, to understand the effect of environmental allergies on PPI response fully. A notable finding is that specific aeroallergens, such as oak, birch, Hormodendrum mold, dust mite (Dermatophagoides pteronyssinus), tree mix, and grass mix allergens, are associated with a lack of PPI response. This raises questions about whether exposure to these allergens during peak seasons could worsen PPI response in allergic EoE patients.
Key takeaways from this study include: (1) the importance of integrating allergen testing in EoE patients, especially those unresponsive to standard PPI therapy or suspected as having allergic phenotypes; (2) the need to monitor and adjust therapy based on clinical and histologic responses; and (3) the necessity of staying abreast of emerging research in this area.
EoE diagnosis presents unique challenges, particularly when patients exhibit exclusive distal esophageal eosinophilia or when discrepancies arise between endoscopic and histologic findings. Eosinophil-derived neurotoxin (EDN), a molecule previously studied for its role in monitoring allergy-mediated inflammatory diseases such as asthma and eczema, can shed light on these diagnostic difficulties.
Thomas and coworkers conducted a retrospective study in which they reviewed 231 pediatric patients, obtaining a minimum of four biopsies from at least two different levels of the esophagus. The study aimed to evaluate whether EDN concentrations, determined through esophageal epithelial brushing at the time of biopsy, could serve as an adjunctive diagnostic tool for EoE.
EDN levels proved sensitive (84.4%) and specific (94.6%) in evaluating active EoE when several measures of EoE were used in patients with active EoE compared with those with inactive EoE and the control group. Previous studies at the same institution had found EDN useful for differentiating EoE patients from non-EoE patients. Moreover, an EDN concentration > 10 μg/mL, when collected through esophageal epithelial brushing, was highly sensitive (97%) and specific (89%) for active EoE. This finding suggests the potential for using EDN as a biochemical marker, enhancing diagnostic accuracy and reducing the need for additional interventions in complex cases.
EDN as a biomarker could be invaluable for distinguishing difficult cases, such as those involving distal eosinophilia, active vs nonactive EoE, or non-EoE conditions, such as gastroesophageal reflux disease. Of note, lower EDN levels were observed in pediatric EoE patients who responded to PPI, suggesting EDN's potential utility in predicting PPI responsiveness. Incorporating the measurement of eosinophilic activity could add a new dimension to existing criteria, equipping clinicians with more precise diagnostic tools and reducing the reliance on multiple procedures. This approach would strengthen the correlation between symptomatic, endoscopic, and histologic data.
The study by Jensen and colleagues sheds light on a crucial aspect of EoE management: the psychosocial burden. A recent EoE diagnosis can be associated with increased symptom burden, somatization, and anxiety in patients and families, underscoring the need for a multidisciplinary approach to patient care that considers both physical and mental health. To date, numerous studies have focused on understanding the disease, its follow-up, and treatment. However, there has been limited exploration of the psychosocial burden and patient-associated factors in EoE.
In this context, this team aimed to enhance our understanding of the burden of EoE by evaluating psychosocial comorbidities, such as disordered sleep, anxiety, and somatization, in a pediatric population with EoE. The study included 87 patients of age 8-18 years who completed validated assessments during routine clinic visits, encompassing EoE symptoms (Pediatric Eosinophilic Esophagitis Symptom Scores, PEESSv2.0), quality of life (PedsQL-EoE), anxiety state and trait (State-Trait Anxiety Inventory for Children, STAI-C), somatization (Children's Somatic Symptoms Inventory-24, CSSI-24), and sleep-disordered breathing (University of Michigan Pediatric Sleep Questionnaire, PSQ).
The mean age of the participants was 12.8 years, highlighting the importance of addressing psychosocial distress in this age group, which undergoes crucial developmental stages. Most patients (82%, 71) had been diagnosed with EoE at least 12 months prior, and 60% (52) were treated with multiple approaches. Additionally, 34% (29) had undergone seven or more esophagogastroduodenoscopies, and nearly one third (33%, 27) had experienced a gastrointestinal-related emergency department visit. These factors potentially increase patient stress due to the continuous need for repeat procedures and hospital visits. An intriguing finding was that patients with shorter disease durations (6-12 months since diagnosis) experienced higher symptom burdens (P = .03). Patients with public insurance had less favorable scores for sleep-disordered breathing (P = .01).
Significantly, patients with neurodevelopmental comorbidities had higher scores for somatic symptoms, trait anxiety, and sleep-disordered breathing, and lower quality-of-life scores, compared with those without such comorbidities (P < .01 for all), suggesting that patients with neurodevelopmental issues might particularly benefit from tailored treatments addressing these aspects of the disease. Furthermore, patients with shorter disease durations since diagnosis exhibited higher somatic symptoms and trait anxiety (both P < .01). The study also revealed that patients with fewer esophagogastroduodenoscopies (1-3) had higher somatic symptom scores (P < .01), state anxiety (P = .02), and trait anxiety (P = .03). EoE-associated symptom burden was significantly correlated with increased somatic symptoms (0.34; 95% CI 0.23-0.45) and decreased quality of life (-0.42; 95% CI -0.59 to -0.25). Concerns about eating food and EoE-associated symptoms were both linked to the EoE-associated symptom burden.
This study has several limitations, including a relatively small sample size, which decreases the power and limits inferences for smaller groups within the sample. There was also an imbalance in gender distribution, with only 26% of patients being female, potentially limiting the generalizability of the findings. Moreover, the study included only EoE patients, lacking a control group for comparison to the general pediatric population.
Highlighting a significant aspect of pediatric EoE treatment, this study illuminates an area that might affect patients' long-term quality of life. It underscores the need for multidisciplinary care for EoE patients, where mental health professionals, such as psychologists or psychiatrists, can play a vital role in improving mental health through early identification and intervention for anxiety and somatization disorders. They can also provide education for patients and families on coping strategies. Peer support groups for children and adolescents could be another beneficial tool, allowing them to share experiences and reduce feelings of isolation.
Physicians who treat chronic diseases such as EoE should consider psychosocial factors, as they can affect both physical and mental quality of life. Using screening tools (such as PEESSv2.0, PedsQL-EoE, STAI-C, CSSI-24, or PSQ) during clinic visits can facilitate a more comprehensive evaluation.
