Serum 25(OH)D concentrations were determined using radioimmunoassay [DiaSorin Inc]. At age 2 years, the mean vitamin D concentration was 23.6 ng/mL. 33% (n=47) of the children were vitamin-D deficient ( 30 ng/mL) and the remaining 119 children (83%) had suboptimal vit D levels (...
1,25-D stimulates the absorption of calcium at the level of the intestine and may also serve to increase calcium and phosphate reabsorption at the kidney level. Renal production of 1,25-D is tightly controlled by parathyroid hormone and is important in the regulation of serum calcium homeostasis...
