Differential effects of phosphate binders on vitamin D metabolism in chronic kidney disease.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Phosphate binders are commonly used in the treatment of patients with hyperphosphatemia.

While phosphate binders are used to lower phosphate, the effects of specific phosphate binder types on vitamin D metabolism are unknown.

Who Took Part

By PubMed's age tags, the people studied were middle-aged adults and older adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

The participants were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

The researchers evaluated changes in serum concentrations of vitamin D metabolites including 24,25-dihydroxyvitamin D3 [24,25(OH)2D3], 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], the ratio of 24,25(OH)2D3 to 25-hydroxyvitamin D [the vitamin D metabolite ratio (VMR)] and the ratio of serum 1,25(OH)2D to 25-hydroxyvitamin D.

What Was Measured

The subject headings attached to it are Acetates, Calcium Compounds, Chelating Agents, Hyperphosphatemia, Lanthanum, Phosphates and Prognosis.

The authors tagged it with the keywords CKD-MBD, chronic renal insufficiency, mineral metabolism, phosphate binders and vitamin D.
