Core Tip

Core tip: Vitamin D deficiency is commonly seen in children diagnosed with inflammatory bowel disease (IBD). Correction of deficiency and optimisation of vitamin D levels likely contribute to enhanced bone health and possibly to the underlying disease course. The optimal regimen and target for vitamin D therapy are not yet elucidated. This systematic analysis aimed to review the available reports of vitamin D therapy in children with IBD to assess efficacy and safety of this treatment, address the diversity of the available trials and provide recommendations for future trials in this field on the basis of the evidence reviewed.
