DISCUSSION

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

An analysis of parathyroid function disclosed similar functioning in patients and controls, with all four measured parameters (maximal secretory capacity, suppressible fraction of I-PTH secretion, sensitivity of PTH secretion to ionized calcium changes or slope, and the set point of I-PTH stimulation by ionized calcium) being alike in both groups. There was a nonsignificant difference […]

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

Biochemical 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 […]

Normal parathyroid function with decreased bone mineral density: SUBJECTS AND METHODS Part 2

Biochemical measurements: Ionized calcium was measured immediately after blood collection with an ICA2 analyzer (Radiometer, Denmark); the interassay coefficients of variance were 3.3% and 2.7%, respectively, at concentrations of 0.77 mmol/L and 1.75 mmol/L. Serum phosphate, creatinine and alkaline phosphatase were quantified by automated colorimetry. Serum 25-hydroxy vitamin D and 1,25-dihydroxy vitamin D were measured […]
