G206(P) Recognising the risk factors: missed opportunities to prevent rickets

Abstract

Aim Implementing the NICE guidance published in November 2014 for vitamin D supplementation of at-risk groups, including all children under-five years of age, would help reduce childhood rickets due to Vitamin D deficiency. Whilst awareness of Vitamin D is increasing, we often assume that UK infants have sufficient calcium dietary intake. This case series highlights rickets arising when insufficient dietary calcium compounds the effects of insufficient Vitamin D. Methods We reviewed case-notes, biochemical and radiological data of four children diagnosed with rickets at our hospital during the past 18 months. Results One child presented aged seven months with seizures. She had a prolonged corrected QT interval secondary to profound hypocalcaemia (corrected calcium 1.49 mmol/L), and vitamin D Deficiency (vitamin D Conclusion This series illustrates commonly recognised risk factors for rickets, namely skin pigmentation, exclusive and prolonged breastfeeding, and the lack of Vitamin D supplementation. Undoubtedly the lack of vitamin D was contributory to the development of rickets and appropriate supplementation could have minimised the adverse skeletal effects. These cases also highlight that a calcium-deplete diet is an additive risk factor for the development of rickets. Infants with cow’s milk protein allergy comprise a clinical group in whom it is important to consider the need for calcium supplementation alongside Vitamin D.
