Systematic review: nutritional therapy in paediatric Crohn’s disease

Abstract

SUMMARY Background At least 25% of individuals diagnosed with Crohn's disease (CD) have onset of disease in childhood. Almost all children with CD have nutri- tional impairments, such as weight loss or stunting, at diagnosis or sub- sequently. Nutritional therapy (exclusive enteral nutrition) is established as a valid and effective treatment in paediatric CD. The advantages of this approach are induction of remission and control of inflammatory changes, mucosal healing, positive benefits to growth and overall nutri- tional status, and avoidance of other medical therapies. Aim To provide a comprehensive up-to-date review of the roles of nutri- tional therapy in CD and of the data supporting this therapy. Methods A search of PubMed was performed with search terms 'enteral nutri- tion', 'nutritional therapy', 'Crohn disease' and 'children'. Relevant arti- cles were selected from this search. In addition, the reference lists of available articles were reviewed for further relevant articles. Results Nutritional therapy offers numerous benefits in the management of CD. Recent work has begun to elucidate the likely mechanisms of this ther- apy. These include direct mucosal anti-inflammatory effects and alter- ation of intestinal microflora. Conclusion Further studies are required to define longer-term effects of nutritional therapy in patients with CD.
