Normal parathyroid function with decreased bone mineral density: RESULTS Part 2

vitamin DBiochemical parameters and parathyroid function: The main characteristics of all normal control subjects and patients and of those who participated in the parathyroid function study are enumerated in Table 1. The biochemical parameters were similar in the two groups except for I-PTH values, which were higher in patients but still within the normal range (Figure 1). Mean 25-hydroxy vitamin D and 1,25-dihydroxy vitamin D values were also normal in patients, but three of them had 25-hydroxy vitamin D values below 35 nmol/L, the lower limit of the normal range. Findings in the two subgroups studied for parathyroid function were similar, illustrating that the higher I-PTH levels in patients were independent of age and sex. The results of parathyroid function are presented in Table 2 and illustrated in Figure 2 as means for each group. Stimulated I-PTH (maximum), nonsuppressible I-PTH (minimum), sensitivity to calcium changes (slope) and set point (ionized calcium values corresponding to half-stimulation) were similar in both groups.
