Vitamin D decreases CD40L gene expression in ulcerative colitis patients: A randomized, double-blinded, placebo-controlled trial.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

The interaction of CD40 ligand (CD40L) and CD40 triggers the induction of pro-inflammatory cytokines.

It has been proposed that vitamin D deficiency might be an important factor, which causes or aggregates the autoimmune situations.

The aim of the present study was to assess the effect of vitamin D on CD40L gene expression in patients with ulcerative colitis (UC).

Who Took Part

The age groups tagged for this paper are adults, both men and women.

Fold changes in CD40L mRNA expression were determined for each patient using the 2-ΔΔCq method.

How the Study Was Run

The design is described as randomized and double-blind.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Neither the participants nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

At baseline and 90 days following the intervention, RNA samples from whole blood were obtained.

What Was Measured

PubMed files the paper under topics including CD40 Ligand, Calcium, Cholecalciferol, Colitis, Ulcerative, Cytokines, Down-Regulation and Gene Expression.
