Orphanet Journal of Rare Diseases | Dietary Management Challenges for School-Age Children with Citrullinemia Type II

Recommend:

This study employs Constructivist Grounded Theory to explore the dietary management challenges faced by families of school-age children with Citrullinemia Type II (Citrin deficiency) in non-family settings, such as schools. The findings reveal that as children enter school, caregivers' direct control diminishes, while the influence of teachers and peers increases, complicating dietary management. Additionally, children's growing autonomy further undermines caregivers' control, highlighting the need for improved strategies to support school-age patients.

 

Literature Overview
This paper, titled 'Challenges in dietary management: a qualitative study on caregivers of preschool and school-age children with citrin deficiency', published in the Orphanet Journal of Rare Diseases, reviews and summarizes the dietary management challenges for school-age children with Citrullinemia Type II (Citrin deficiency). The article notes that Citrullinemia Type II is an autosomal recessive disorder caused by mutations in the SLC25A13 gene. It presents clinically with cholestatic jaundice, liver dysfunction, growth failure, and lipid metabolism disorders. Currently, there are no specific pharmacological treatments; dietary management primarily involves a high-protein, high-fat, low-carbohydrate regimen. Through qualitative interviews, the study uncovers the complexities of managing dietary restrictions in non-family environments such as schools. It emphasizes that caregivers lose direct dietary control as children enter school, while teachers and peers gain influence, and children's autonomy increases, leading to decreased compliance with dietary guidelines.

Background Knowledge
Citrullinemia Type II is a metabolic disorder caused by impaired function of the mitochondrial aspartate/glutamate carrier 1 (AGC1), due to mutations in the SLC25A13 gene. In the neonatal period, the disease manifests as neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD), and may progress to adult-onset Citrullinemia Type II (CTLN2) in school-age children. The main treatment is a low-carbohydrate diet. Given the lifelong nature of the disease, caregivers must maintain long-term dietary control, and the introduction of the school environment significantly increases complexity. Current research focuses on optimizing dietary formulations, adjusting nutrient ratios, and improving disease screening and diagnosis, but there is limited research on dietary management challenges in non-family environments. This study fills that gap by highlighting the changing role of caregivers in dietary management during schooling, and the influence of teachers, peers, and children’s autonomy on compliance. The research provides theoretical support for improving dietary management in school settings, emphasizing the importance of multi-stakeholder collaboration and offering insights for future intervention strategies.

Research Methods and Procedures
The study uses Constructivist Grounded Theory (CGT) to analyze data collected via semi-structured interviews with 17 caregivers (16 mothers, 1 grandmother) of children with Citrullinemia Type II. The interviews explore changes in dietary environments, the influence of teachers and peers, and the development of children's autonomy. Researchers used line-by-line coding to consolidate initial codes into focused codes, ultimately forming a theoretical framework that explains how the school environment affects dietary control.

Key Findings and Perspectives

• After starting school, caregivers' direct control over children's diet gradually weakens, while teachers and peers begin to play a more active role in dietary management.
• Due to concerns about stigma or discrimination, caregivers tend to conceal the child's condition to protect their social image and future opportunities.
• School meals are generally high in carbohydrates, and many schools prohibit outside food, limiting flexibility in dietary management.
• Increased child autonomy leads to consumption of inappropriate foods in the absence of supervision, further reducing dietary compliance.
• Over time, caregivers recognize the importance of teaching children self-management skills to adapt to social settings and improve autonomous decision-making.

Significance and Future Directions
The study provides a new qualitative perspective on dietary management for Citrullinemia Type II, highlighting the complexity introduced by the school environment. Future research should expand to include teachers and nutritionists to gain a more comprehensive understanding. The findings can also inform the development of personalized dietary policies in schools, helping to improve the dietary environment for children with rare diseases.

Conclusion
This study reveals multiple challenges in dietary management for children with Citrullinemia Type II after entering school. Caregivers gradually lose control over dietary decisions, and teachers, peers, and children's autonomy become increasingly influential. The study highlights that school meals are typically high in carbohydrates and lack flexibility, posing real barriers for caregivers. Moreover, children's autonomous behaviors may lead to consumption of restricted foods. These findings provide a theoretical foundation for designing future interventions, emphasizing the importance of collaboration among all stakeholders and the need for better understanding and support for special dietary needs within the school setting.
