A Case of Extremely High Intact \\{PTH\\} Levels After Total Parathyroidectomy With Auto Transplantation in a Patient on Peritoneal DialysisIgG4tubulointerstitial nephritisrenal arteritisImmunoglobulin G4 (IgG4)-related tubulointerstitial nephritis is a newly recognized clinicopathologic entity that may ...
The whole-PTH/intact-PTH ratio was compared in patients with high PTH levels (intact-PTH ≥300 pg/ ml; high PTH group, n = 32), moderate PTH levels (intact-PTH >150-0.5 cm(3) suggesting nodular hyperplasia, as determined by power Doppler ultrasonography (hyperplasia group) with seven ...
The PTH levels decreased within the target range in about one-fourth of the patients at baseline and at the end of the study. The bone biopsies of two-thirds of the patients were classified as showing low turnover and a one-fourth showed high turnover, the remainder having normal turnover...
The goal was to define the inconsistencies between PTH assays when values range from normal to slightly high levels. To examine serum intact PTH (1–84), we compared 42 serum samples between different assays and methods. The three methods used included the following: (a) enzyme-linked ...
Serum intact parathyroid hormone (PTH) concentration was measured by a two-site immunoradiometric assay (IRMA) in normal subjects and patients with various parathyroid disorders. Serum intact PTH levels were all within the detection limit of the IRMA in normal subjects, and there was a significant...
In contrast, if the relative PTH15 is higher than 30%, high postoperative PTH values are predicted with a probability of 86.7%. Although there remain some borderline cases, intraoperative iPTH measurement is accurate and also can be useful in patients with renal hyperparathyroidism. 展开 关键词: ...
The parathyroid hormone (PTH) molecule is a polypeptide composed of an 84-amino acid sequence with an active amino terminal on one end and an inactive carboxyl unit on the other. Measurement of the intact PTH (iPTH) is an accurate representation of the true parathyroid state. In recent years...
C-Terminal FGF-23 and Valvular Calcification This study found high mean C-terminal FGF-23 in regular HD patients (11,228.6 ± 6,740 RU/mL). High FGF-23 in CKD happens due to hyperphosphatemia. Hyperphosphatemia causes hypocalcemia that stimulates PTH secretion. In bone, PTH stimulates FGF...
Such antigens, antibodies and methods producing the same according to the present invention are useful in determining bioactive intact PTH levels in serum, plasma, and/or cell culture media. Such antibodies further possess a high degree of species cross-reactivity, but substantially mitigated cross-...
Impairment of longitudinal growth among children with chronic renal failure (CRF) may be partly attributable to the inhibition of insulin-like growth factor (IGF) activity by an excess amount of high-affinity IGF-binding proteins (IGFBP). Elevated levels of immunoreactive IGFBP-4 in CRF serum are...
