BACKGROUND: Vitamin D deficiency is highly prevalent in children with intestinal failure (IF) who receive parenteral nutrition (PN), but data on vitamin D status after achieving enteral autonomy (EA) are limited. We aimed to evaluate the prevalence of vitamin D deficiency in this population while exploring clinical variables that may be associated with its development.
METHODS: A retrospective review was performed on 29 children with IF who had achieved EA. Deficiency was defined as a mean serum 25-hydroxyvitamin D <30 ng/ml.
DATA RESULTS: Sixty-six percent of children had at least one deficient level during the study period, with 38% being deficient based on the mean vitamin D levels. Eighty-four percent had radiologic evidence of osteopenia. Compared with the sufficient group (n=18), the deficient group (n=11) received higher daily mean vitamin D doses (2246 vs 920 IU; P=.02), had shorter remnant small-bowel length (53.8 vs 82.1 cm; P=.03), and were PN dependent for a longer duration (1.3 vs 0.58 years; P=.01). Univariate analyses revealed longer remnant gut length (odds ratio [OR] = 1.03; P=.04) and shorter duration of PN (OR = 0.26; P=.04) to be significantly associated with sufficient vitamin D status.
CONCLUSION: Vitamin D deficiency and osteopenia are highly prevalent in pediatric patients with a history of IF who have achieved EA, despite enteral supplementation with higher than standard doses. Shorter remnant small-bowel length and longer duration of PN were associated with vitamin D deficiency. These findings emphasize the importance of prolonged surveillance and highlight the need for alternate dosing regimens.
