title: [Correlation of serum Bio-intact PTH (1-84) and parathyroid gland size in hemodialysed patients].
abstract: Bio-intact parathyroid hormone (Bio-PTH) assay, which measures exclusively intact PTH (1-84) molecule, provides a better assay for estimating parathyroid function in hemodialysis (HD) patients, whereas intact PTH (I-PTH) assay cross-react with PTH (7-84) as well as PTH (1-84). We have found that PTH (7-84) accumulated into serum of hemodialysis patients due probably to its impaired excretion into urine. We have reported that parathyroid gland size is one of major predictor for vitamin D responsiveness in secondary hyperparathyroidism. Therefore, we investigated whether serum Bio-PTH, in comparison with serum I-PTH, may provide a relevant assay to estimate parathyroid function as evidence by its correlation with parathyroid gland size on ultrasound examination.
