Pth Level

In 12 children aged four-and-a-half to 18 years (mean 11 ±4.2) undergoing continuous ambulatory peritoneal dialysis (CAPO), serum intact parathyroid hormone (iPTH), ionized calcium (iCa) levels, and calcium mass transfer (CaMT) were measured on three consecutive days: day 1, after a four-hour interval between dialyses; on day 2, after four hours dwell time with peritoneal dialysis (PD) Ca 3.5 mEq/L; and on day 3, after four hours dwell time with PD Ca 2.5 mEq/L. A significantly more negative CaMT was found when PD Ca 2.5 mEq/L was used, as compared with values obtained using PD Ca 3.5 mEq/L. Significantly lower parathyroid hormone (PTH) values were found after the interval between exchanges. We conclude that in order to properly evaluate parathyroid gland function and to decide whether or not to give vitamin D metabolites, a protocol for determining PTH should be standardized.

SummaryA 12-year-old, female, spayed, mixed-breed dog with acute lethargy, anorexia and weakness and markedly elevated total and ionised calcium concentration showed an enlarged left cranial parathyroid gland on ultrasonography of the ventral neck. Despite preoperative therapy with furosemide and calcitonin, there was no decline of plasma ionised calcium concentration. The dog deteriorated rapidly and was euthanased two days after initial presentation. Postmortem histopathology revealed parathyroid tissue with characteristics of malignancy as local and vascular invasion. Immunohistochemistry showed parathyroid hormone positive staining of these cells. Unusual clinical presentation and histopathological characteristics are discussed.
