Eosinophilic esophagitis in children: doubts and future perspectives

Area of Science:

• Immunology
• Gastroenterology
• Pediatric Medicine

Background:

• Eosinophilic esophagitis (EoE) is a chronic immune-mediated disorder and a leading cause of food impaction.
• Its pathogenesis involves genetic, environmental, and immune factors.
• Current management strategies are reviewed, focusing on pediatric patients and novel monoclonal antibody therapies.

Purpose of the Study:

• To review current evidence on EoE management in pediatric patients.
• To focus on new findings regarding the efficacy and safety of monoclonal antibodies for EoE.
• To discuss the limitations of current therapies and potential future directions.

Main Methods:

• Review of current evidence on EoE management in pediatric age.
• Focus on new findings related to monoclonal antibodies' efficacy and safety.
• Analysis of existing studies on monoclonal antibodies in EoE.

Main Results:

• Conventional therapies, including topical corticosteroids, have limitations and potential adverse effects in children.
• Monoclonal antibodies show histological improvement in EoE but not always significant clinical benefits.
• The relationship between reduced eosinophils and clinical symptom improvement is not always significant, indicating the role of other cells.

Conclusions:

• Monoclonal antibodies targeting single pathways may not fully resolve EoE's complex inflammatory cycle.
• Combined biological therapies targeting multiple molecules or cells, potentially with conventional treatments, may offer better outcomes.
• Further research is needed to identify optimal therapeutic strategies targeting cells involved in esophageal remodeling and reversing histological changes in EoE.
