Can Vitamin D Treatment Help Treat Moderate to Severe Atopic Dermatitis in Young Children? the D-Vex Pilot Study

Vitamin D is known to have a regulatory influence on both the immune system and skin barrier function. Studies in paediatric populations have found an inverse association of vitamin D levels and with both prevalence and severity of atopic dermatitis (AD). Trials of vitamin D as a treatment for AD are limited in number and size. There has never been a placebo-controlled randomised controlled trial of stoss high dose versus daily standard dose for the treatment of AD. Further, no trials have explored the presence of vitamin D pathway genes and response to treatment of AD. This pilot study will be used as a reference to determine outcomes and feasibility for undertaking a larger and more in depth definitive study.
