ABSTRACT
Coeliac disease and food allergy management primarily relies on the strict avoidance of dietary antigens. This approach is challenging to maintain in real-world settings and in food allergy carries the risk of life-threatening anaphylaxis. Despite their distinct pathogenesis, both disorders are driven by maladaptive responses to dietary proteins, creating opportunities for shared treatment strategies. In food allergy, desensitisation therapies such as oral, sublingual, and epicutaneous immunotherapy are well-established, complemented by biologics like omalizumab and dupilumab. However, the induction of sustained tolerance remains challenging. In contrast, therapeutic advancements for coeliac disease are still in their early stages. Current efforts focus on gluten detoxification or modification, immune blockade or modulation, tolerogenic approaches, and barrier restoration. Emerging therapies, including JAK and BTK inhibitors and microbiome-targeted interventions, support further targeted treatment options for both conditions. Biomarkers tracking gluten-specific T cells have emerged as valuable tools for immunomonitoring and symptom assessment in coeliac disease, although standardisation of patient-reported outcome measures and gluten challenge protocols is still needed. Food allergy trials are reliant on double-blind placebo-controlled food challenges to measure allergen reactivity, but these are time-consuming, carry risks, and underscore the need for surrogate biomarkers. The successful development of immune-targeted therapies will require building an immune toolset to optimally assess systemic responses to antigens in both conditions. Clinically, this could lead to better outcomes for patients who might otherwise remain undiagnosed or untreated due to the absence of significant enteropathy or allergen-specific symptoms.
