Vitamin D deficiency is the most common cause of rickets. Vitamin D deficiency prevents the efficient absorption of dietary calcium and phosphorus. In a vitamin D–deficient state, only 10–15% of dietary calcium and 50–60% of dietary phosphorus are absorbed. The poor absorption of calcium causes a decrease in serum-ionized calcium levels. This is immediately recognized by the calcium sensor in the parathyroid glands, resulting in an increase in the expression, synthesis, and secretion of parathyroid hormone (PTH) (1, 20, 22, 27). PTH conserves calcium by increasing tubular reabsorption of calcium in both the proximal and distal convoluted tubules. PTH, like 1,25(OH)2D, enhances the expression of RANKL on osteoblasts to increase the production of mature osteoclasts to mobilize calcium stores from the skeleton. PTH also decreases phosphorus reabsorption in the kidney, causing loss of phosphorus into the urine (Figure 4). The serum calcium level is usually normal in a vitamin D–deficient infant or child. However, the serum phosphorus level is low, and thus there is inadequate calcium-phosphorus product, which is necessary to mineralize the osteoid laid down by osteoblasts (1, 20, 22, 24, 28) (Figure 4). Thus, typically, infants with vitamin D–deficiency rickets have a normal serum calcium level, low normal or low fasting serum phosphorus levels, elevated alkaline phosphatase levels, and low 25(OH)D levels (<15 ng/ml) (23, 28–31) (Table 2). The secondary hyperparathyroidism stimulates the kidneys to produce 1,25(OH)2D, and thus, 1,25(OH)2D levels are normal or often elevated, which is why the measurement of 1,25(OH)2D is of no value in determining a state of vitamin D deficiency (24). Only when the calcium stores in the skeleton are totally depleted will the infant or child become hypocalcemic.
