When Supplemental Formula Is Essential: Overcoming Barriers to Hypoallergenic Formula Access for Patients With Food Allergies

Disease Burden and Spectrum of Symptoms that Impact Quality of Life in Pediatric Patients with Eosinophilic Esophagitis

Eosinophilic esophagitis (EoE) is a progressive type 2 inflammatory disease characterized by symptoms related to esophageal dysfunction and significant esophageal eosinophilic infiltration. It can affect patients from infancy through adulthood. Pediatric EoE has a multidimensional impact on the quality of life of both patients and their families. Nonspecific symptoms mimicking other gastrointestinal conditions, such as food refusal, failure to thrive, and feeding difficulties, may profoundly affect young children's eating skills, growth, and psychosocial status, as well as impact family financial conditions. In adolescence, dysphagia and esophageal food impactions often lead to feeding-related anxiety and influence social lives. Delays in diagnosis, arising from lack of awareness among families and clinicians and compensatory eating behaviors, could increase the risk of fibrostenotic complications, which may ultimately add to the symptom burden. Currently available treatment options include proton pump inhibitors, dietary therapies, swallowed topical steroids, esophageal dilation, and biologic therapy. Despite the efficacy of these approaches, disease burden may be further impacted by their limitations, including poor adherence rates, refractory disease, potential long-term safety concerns, and high costs for care. Thus, there is a need for more timely diagnosis in clinical practice and novel targeted disease-modifying therapies better tailored to treat various phenotypes of EoE, aimed at reducing the physical and psychosocial burdens on patients and their caregivers.

Dietary Management of Non-EoE Eosinophilic Gastrointestinal Diseases

Patients with non-eosinophilic esophagitis eosinophilic gastrointestinal diseases (non-EoE EGIDs) are prone to nutritional deficiencies due to food-avoidant behaviors, malabsorption, and high nutrition impact symptoms. Nutrient deficiencies correspond to the segment, depth, and extent of the gastrointestinal tract involved and can impact organs distant from the gut. Patients with non-EoE EGIDs are often atopic, and some appear to respond to dietary avoidance of specific food allergens. Tests to identify food triggers other than response to elimination diets are lacking. Dietary restriction therapy should be considered in such patients and is best implemented through a multidisciplinary approach to avoid nutritional complications.

Barriers to Timely Diagnosis of Eosinophilic Gastrointestinal Diseases

Although eosinophilic gastrointestinal diseases, including eosinophilic esophagitis, have been described over the past 2 to 3 decades, barriers to diagnosis and treatment are common and compounded by issues related to social determinants of health, race, ethnicity, and access to care. These barriers contribute to delays in diagnosis, resulting in persistent inflammation in the gastrointestinal tract, which can have significant consequences, including fibrostenotic complications in adults, failure to thrive in children, and decreased quality of life in all affected patients. In this commentary, we summarize gaps in knowledge regarding the epidemiology of eosinophilic gastrointestinal diseases, highlight barriers to diagnosis, discuss potential approaches based on best practices in other atopic and chronic gastrointestinal diseases, and provide recommendations for reducing barriers to timely diagnosis of eosinophilic gastrointestinal diseases in underserved populations.
