-In reality, 25-D may account for only a very small percentage of variation in PTH levels, especially when subjects are taking adequate calcium. Several studies have shown that low magnesium, increasing age, or elevated serum phosphate and creatinine due to kidney disease also greatly contribute to the level of PTH, causing researchers at the University Hospital of New Norway to conclude that elevated PTH “is therefore probably a result of a combination of factors.” (({{pubmed>long:16369900}})) It’s not surprising then, that several studies have noted that giving vitamin D to patients with low levels of 25-D often does nothing to bring PTH back to normal levels.(({{pubmed>long:6611345}}))+In reality, 25-D may account for only a very small percentage of variation in PTH levels, especially when subjects are taking adequate calcium.

 In the end, it is perfectly possible that when calcium intake is adequate, most of what remains of the association between low 25-D and elevated PTH is simply part of the pathogenesis of chronic disease and osteoporosis. Just as the low 25-D seen in patients with chronic disease is the //result// rather than the //cause// of the disease process, elevated PTH in patients with low 25-D may simply be an indicator of inflammation caused by the Th1 pathogens. In the end, it is perfectly possible that when calcium intake is adequate, most of what remains of the association between low 25-D and elevated PTH is simply part of the pathogenesis of chronic disease and osteoporosis.
