Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) is common in children, but its course is heterogeneous and current risk tools are largely static and population-based. No validated pediatric MASLD digital twin currently exists, and no prior synthesis has defined how digital-twin methodology should be adapted to childhood, when growth and puberty change the interpretation of clinical data. This narrative review evaluates digital-twin models and candidate inputs for pediatric MASLD, including noninvasive diagnostics, imaging, body composition, molecular and genetic markers, lifestyle, and social context. We explicitly distinguish direct pediatric MASLD evidence from adult MASLD or metabolic evidence, evidence from other pediatric diseases, and generic digital- twin and artificial-intelligence methodology. We then propose an author-derived, investigational three-layer architecture: Longitudinal multimodal inputs; an age- and puberty-referenced twin engine; and clinician-facing candidate outputs. Initial research use should focus on association-based prognostic monitoring and validation of modular components. Adaptive follow-up and individualized risk estimates require prospective validation, while causal treatment-effect simulation is a separate and more demanding objective. Clinical deployment would require interoperable electronic health record data, prospective multicenter validation, transparent reporting across subgroups, explainability, family-centered consent and assent, cost-effective implementation, and regulatory oversight of adaptive software. The near-term priority is rigorous evaluation of a minimum viable core model rather than deployment of a complete twin. No evidence-based timeline for clinical implementation can yet be specified.
