AIM: To assess the impact of vitamin D supplementation (cholecalciferol) on the insulin sensitivity and metabolic health of patients with chronic kidney disease (CKD). METHODS: Twenty-eight adult patients with CKD stages 3-4 were recruited from the outpatient department of the Princess Alexandra Hospital (Brisbane, Australia) to a double-blind randomized trial of cholecalciferol (vitamin D3) 2000 IU/day or placebo for 6 months. Metabolic parameters at baseline were compared with 20 non-CKD adults. The primary outcome was an improvement in insulin resistance (glucose disposal rate, GDR) at 6 months (quantified by hyperinsulinaemic euglycaemic clamp). Carbohydrate and lipid oxidation rates wer..
