Vitamin d level and severity of Crohn's disease

[Crohn2357]

I've been reading this review article about vitamin d and ibd: http://www.hindawi.com/journals/bmri/2015/470805/
and I wondered, in your experience, do you think there is a definitive relation between your serum vitamin d level and severity of your disease ?
