Effect of active vitamin-D on left ventricular mass index: Results of a randomized controlled trial in type 2 diabetes and chronic kidney disease

What Was Tested

Researchers studied Parathyroid Hormone (PTH 1-84) in this randomized controlled trial publication.

The researchers explored the effects of active vitamin-D (calcitriol) treatment on left ventricular mass in patients with type-2 diabetes (T2D) and chronic kidney disease (CKD).

Who Took Part

PubMed tags the participants as men only.

Patients with T2D, CKD stage-3 and raised left ventricular mass on stable renin angiotensin aldosterone system blockade, who all had elevated intact parathyroid hormone were eligible.

How the Study Was Run

The design is described as randomized, double-blind, placebo-controlled and parallel-group.

Random assignment meant chance, not the researchers, decided who got Parathyroid Hormone (PTH 1-84) and who got the comparison, which limits bias.

As a double-blind Parathyroid Hormone (PTH 1-84) study, the assignments were hidden from both participants and investigators until the end.

Some participants received a placebo instead of Parathyroid Hormone (PTH 1-84), giving a reference point.

Groups ran in parallel: each of the participants stayed in one arm throughout.

Secondary endpoints included interstitial myocardial fibrosis, assessed with cardiac magnetic resonance imaging.

What Was Measured

Topics PubMed links to this paper include Vitamin D, Calcitriol, Diabetes Mellitus, Type 2, Vitamins, Ergocalciferols, Renal Insufficiency, Chronic and Parathyroid Hormone.
