carboxyl-terminal parathyroid hormone

07/01/1993 - "The aim of the study was to compare the value of intact and C-terminal PTH measurements in predicting the osteodystrophic bone lesion in predialysis patients with chronic renal failure (CRF). "
05/20/1987 - "[Studies on the half-life of C-terminal parathyroid hormone in chronic renal failure]."
06/01/2002 - "Intact-PTH assay measures not only (1-84) -PTH [biological active form] but also (7-84) -PTH as a C-terminal PTH fragment with competitive inhibitory effect in end stage renal disease (ESRD) patients. "
12/01/2009 - "Heterogeneity of carboxyl-terminal parathyroid hormone circulating forms in patients with hyperparathyroidism due to end stage renal disease."
07/01/1993 - "Two-site immunoradiometric intact parathyroid hormone assay versus C-terminal parathyroid hormone in predicting osteodystrophic bone lesions in predialysis chronic renal failure."

04/26/1993 - "The serum carboxy-terminal parathyroid hormone levels were increased because of renal failure. "
04/01/1993 - "Length velocity standard deviation score (LV-SDS) did not correlate with degree of renal insufficiency at any age, but average LV-SDS did relate significantly and inversely to C-terminal parathyroid hormone (PTH) levels. "
01/01/1985 - "The results show that there seems to be a better clinical correlation for hyperparathyroidism, in haemodialysis patients and patients with renal failure, using N-terminal PTH determinations rather than C-terminal PTH determinations, because in haemodialysis patients and patients with renal failure split products of the C-terminal region of PTH give unrealistically high PTH results."
01/01/1985 - "In patients with renal failure, creatinine clearance less than 30 ml/min, both C-terminal and N-terminal PTH were elevated in five patients, C-terminal PTH in 12 patients and N-terminal PTH in none of the patients studied. "
05/01/2000 - "We evaluated indicators of calcium and phosphorus metabolism and creatinine clearance (CrCl) in the progressive renal failure groups, and the HPLC profile of I-PTH and C-terminal PTH in all groups. "

11/01/1983 - "The carboxyl-terminal parathyroid hormone response varied among different donors, but on the average, decreased slightly before gradually rising during the citrate-induced hypocalcemia. "
09/01/1983 - "Hypoparathyroidism (hypocalcemia, hyperphosphatemia, mild hypomagnesemia, and inappropriately low serum C-terminal parathyroid hormone concentration) was found in six members of a family representing three successive generations. "
01/01/1986 - "Diabetic patients had lower C-terminal parathyroid hormone (cPTH) levels before hemodialysis than uremic control patients and showed a significantly smaller increase in cPTH during hypocalcemia. "
09/01/1983 - "Patients with osteomalacia had a blunted maximum amino terminal parathyroid hormone response (+/- SD) (0.39 +/- 0.33 vs. 0.87 +/- 0.53 ng/ml, P less than 0.05) and maximum carboxy terminal parathyroid hormone response (+/- SD) (0.36 +/- 0.20 vs. 0.84 +/- 0.47, P less than 0.02) to hypocalcemia. "
09/01/1993 - "Characteristic biochemical abnormalities included hypocalcemia, hypophosphatemia, and elevated levels of serum acid phosphatase, alkaline phosphatase, c-terminal parathyroid hormone, and 1,25-dihydroxyvitamin D. "

01/01/1988 - "In cases of primary hyperparathyroidism, elevated C-terminal PTH level should be diagnostic. "
01/01/1985 - "Fourteen patients with primary hyperparathyroidism were studied; in ten both C-terminal and N-terminal PTH were elevated, in two only C-terminal PTH and in another two only N-terminal PTH was elevated. "
01/01/1986 - "Healthy adults revealed PTH-peptide levels of 153 +/- 86 pg/ml (mean +/- 2 SD); 2 SD range: 67-239 pg/ml. C-terminal PTH-peptide (70-84 hPTH) concentration was normal in patients with primary hyperparathyroidism and chronic renal failure, thus excluding that neither the kidney nor the parathyroid gland is involved in the generation of this C-terminal PTH-peptide sequence. "

07/01/1986 - "Mild hypercalcemia, hypophosphatemia and elevated C-terminal PTH levels were associated with oliguria. "
01/01/1991 - "There seems to be a positive correlation between hypophosphatemia and osteomalacia but carboxy-terminal parathyroid hormone (C-PTH) and calcium (Ca) levels in the serum were not related to the degree of osteomalacia. "
09/01/1993 - "Characteristic biochemical abnormalities included hypocalcemia, hypophosphatemia, and elevated levels of serum acid phosphatase, alkaline phosphatase, c-terminal parathyroid hormone, and 1,25-dihydroxyvitamin D. "
