...Martin Munteanu; Elisabeth Resch; Victor Bildheim; Sabine Hoffjan; Bernhard Erdlenbruch; Agnès Linglart; Corinna Grasemann Introduction: Pseudohypoparathyroidism 1A (PHP1A) is the best-known representative of inactivating parathyroid hormone (PTH)/PTHrP-signaling disorders (iPPSD). The associated...

... identified in vitamin D-resistant rickets. Work with parathyroid hormone (PTH) began much later, as the parathyroids were not identified until the late 19th century. In 1925, James B. Collip (of insulin fame) identified PTH by its ability to correct tetany in parathyroidectomized dogs, but only in the 1970s...

In addition to these alterations, patients may develop other hormonal resistances, leading to overt or subclinical...

...) and parathyroid hormone (PTH) concentration at 12 months. Severe hypercalcemia was defined as Ca-ion exceeding the reference limit (1.16–1.39 mmol/L) by 10%. Results: No severe hypercalcemia occurred. Mild hypercalcemia (1.40–1.52 mmol/L) was present at 6 months in 28% and at 12 months in 2% of infants. At 12...

However, there are few data regarding PTH levels in childhood...

...Z. Amini; S. Bryant; C. Smith; R. Singh; S. Kumar Background/Aims: Serum 25 hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH) levels correlate inversely. The 25(OH)D level at which PTH is maximally suppressed and below which PTH begins to rise (inflection point) has been used to define...

...Bo Ahrén; Anders Bergenfelz To study possible influences of a mild increase in serum-ionized calcium concentration that is seen during daily life on circulating parathyroid hormone (PTH) immunoheterogeneity, we used sequence-specific PTH assays to determine serum intact PTH, C-terminal PTH and N...

... that correction of hypercalcemia should disinhibit circulating parathyroid hormone (PTH) levels, irrespective of the underlying disease. We have tested this hypothesis in subjects with multiple myeloma (MM) and squamous cell carcinoma (SCC) treated with pamidronate. In the MM group, PTH levels returned to normal...

...Anders Bergenfelz; Bo Ahrén Since osteocalcin has been suggested to play a role in calcium homeostasis, we investigated its serum levels in 6 healthy subjects during a rapid calcium infusion. Serum levels of intact parathyroid hormone (PTH), 25-hydroxyvitamin D [25-(OH) D 3 ] and 1,25...

Further, the dynamic function of the parathyroid glands was investigated by an oral calcium load test pre- and at 3 months postoperatively. At follow-up, all patients were...

...Anders Bergenfelz; Stig Valdermarsson; Bo Ahrén Primary hyperparathyroidism (pHPT) is associated with a right-shifted relation between parathyroid hormone (PTH) secretion and calcium. However, it is also possible that a decreased suppressibility of PTH secretion by calcium is important...

...J. Aloia; D. Powell; E. Mendizibal; M. Roginsky Parathyroid function was assessed in six acromegalic subjects by measurement of serum levels of parathyroid hormone (PTH). Only one patient had increased PTH levels. These findings suggest that hyperparathyroidism does not uniformly occur...
