|a For measurement of parathyroid hormone (PTH), the intact PTH (I-PTH) assay is generally used. However, I-PTH assay apparently detects PTH 7-84 fragments, in addition to PTH 1-84. The whole PTH (W-PTH) assay exhibits no cross-reactivity with PTH 7-84. Ratio of PTH 1-84 to non-(1-84) PTH has been proposed as a non-invasive indicator of bone turnover in patients with end-stage renal disease (ESRD). We evaluated the efficacy of W-PTH assay and 1-84/non-(1-84) PTH ratio in hemodialysis patients and patients who had undergone parathyroidectomy. PTH levels were measured using W-PTH and I-PTH assays in 138 hemodialysis patients, 27 healthy controls and 10 patients who were scheduled to undergo parathyroidectomy for secondary hyperparathyroidism. Alkaline phosphatase, bone alkaline phosphatase and intact osteocalcin were also measured for comparison with 1-84/non-(1-84) PTH ratio. W-PTH was strongly correlated with I-PTH in both groups, and with all three bone metabolic markers in hemodialysis patients. In hemodialysis patients, both PTH and bone metabolic markers were significantly lower in the subgroup with a PTH ratio < 1.0 than in the subgroup with a PTH ratio > or = 1.0. However, PTH ratio exhibited no significant correlation with bone metabolism markers. PTH ratio was higher after parathyroidectomy than before. W-PTH and I-PTH assays offer identical indicators of bone metabolism in ESRD patients. However, 1-84/non-(1-84) PTH ratio may be of limited diagnostic use regarding bone turnover if a cut-off value of 1.0 is used. PTH 1-84 may be secreted relatively more than non-(1-84) PTH after parathyroidectomy, due to decreases in serum calcium. As the W-PTH assay allows easy calculation of non-(1-84) PTH by subtracting the I-PTH value, this assay contributes to identification of the function of non-(1-84) PTH fragments in various conditions
