Establishing an appropriate level of vitamin D supplementation in paediatric patients with recessive dystrophic epidermolysis bullosa

All patients with RDEB require a supplement or a formula or enteral/sip feed containing vitamin D to maintain sufficient serum vitamin D. The dose required increases with age and can be up to three times higher than the RNI for the normal population. Compliance may improve using a once-weekly loading dose of vitamin D3. Vitamin D deficiency was not solely causative of a low BMD Z score.
