Bone disease in diabetes.

The relationship between diabetes and bone disease is complex. While low bone mineral density (BMD) is consistently observed in type 1 diabetes (T1DM), in type 2 diabetes (T2DM) bone mineral density is similar to or higher than in non diabetic subjects. Yet, for both types of diabetes bone appears to be more fragile for a given density.

Biochemical effects of calcifediol supplementation in mild, asymptomatic, hyperparathyroidism with concomitant vitamin D deficiency.

It has been proposed to cautiously supplement with vitamin D to any patient with asymptomatic primary hyperparathyroidism (PHTP) and a plasma 25-hydroxyvitamin D [25(OH)D] concentration <50 nmol/l. Evidence about the safeness of this intervention is limited to two studies. Our aim was to prospectively assess the biochemical effects of one-year 25(OH)D supplementation in this context.
