Can screening for low vitamin D levels prevent bone health complications in paediatric oncology patients?

Abstract

Background: No international standards include vitamin D levels at diagnosis or during treatment. It is included in the Children's Oncology Group long-term follow-up guidelines. However, bone health complications (like osteopenia and atraumatic fractures) can occur at diagnosis or during treatment as well. Cases: In this small case series, we illustrate the complexity of bone health complications among our broad paediatric oncology population. If the vitamin D level is low we supplement the patient with one standard oral dose (150 000 units for 1–2 year olds, 300 000 units for 2–5 year olds and 600 000 units for >5 year olds). We do not adjust depending on diagnosis. Conclusion: Because of the potentially negative outcomes on short, medium and long term, we recommend checking vitamin D levels on diagnosis for all newly diagnosed patients. It is a simple, low cost test and one dose of oral supplementation can easily treat the deficiency.
