Low-risk paediatric Crohn's disease: A narrative review of current evidence and unmet research needs.

While current paediatric management increasingly favours early intensive treatment for children and adolescents with Crohn's disease (CD) at high risk of disease progression, a smaller subset of patients presents with a potentially 'low-risk' disease phenotype. Identifying these children is clinically challenging, as overtreatment may expose them to unnecessary risks and costs, whereas undertreatment may allow irreversible bowel damage and complications to develop. This narrative review summarises the current evidence on the definition, assessment, treatment, and monitoring of low-risk paediatric CD, highlighting existing knowledge gaps and future research priorities. At present, no consensus definition of low-risk paediatric CD exists, and disease classification relies largely on the absence of recognised high-risk features rather than validated criteria. Similarly, unlike adult practice, no paediatric prognostic model is available to identify children likely to follow a persistently mild disease course. Current assessment requires integration of clinical indices, inflammatory biomarkers, endoscopy, cross-sectional imaging, and evaluation of growth and nutritional status. Dietary treatment (Exclusive Enteral Nutrition and emerging dietary strategies, including the CD Exclusion Diet [CDED] and the Tasty & Healthy [T&H]] remains the commonest induction therapy. Budesonide or antibiotics (azithromycin and metronidazole) represent an appropriate alternative for selected children. CDED and the T&H diet may also represent attractive medium term treatment options, although robust maintenance data are still awaited. Prospective studies are needed to establish a consensus definition, develop paediatric-specific prediction models, optimise risk stratification, and determine the most effective long-term therapeutic and monitoring approaches for the 'low-risk' population.
