Immunoreactive parathyroid hormone and calcitonin in children's cerebrospinal fluid. 1986

G Saggese, and S Bertelloni, and G I Baroncelli, and A Abadessa, and P Macchia, and U Bottone

Cerebrospinal fluid (CSF) levels of immunoreactive parathyroid hormone (iPTH) and immunoreactive calcitonin (iCT) were measured by radioimmunoassay in 23 outpatient leukemic children on maintenance chemotherapy. These hormones were detectable in the CSF of all patients: iPTH 148 +/- 11 pg/ml (mean +/- SEM); iCT 14.3 +/- 0.8 pg/ml. iPTH and iCT were also measured in serum (iPTH 396 +/- 18 pg/ml; iCT 32.3 +/- 1.4 pg/ml). CSF values were significantly lower (p less than 0.001) than serum concentrations; no significant correlation between the two compartments was found. Our study indicates the presence of iPTH and iCT in the CSF of children.

UI MeSH Term Description Entries
D007223 Infant A child between 1 and 23 months of age. Infants
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D010281 Parathyroid Hormone A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D002116 Calcitonin A peptide hormone that lowers calcium concentration in the blood. In humans, it is released by thyroid cells and acts to decrease the formation and absorptive activity of osteoclasts. Its role in regulating plasma calcium is much greater in children and in certain diseases than in normal adults.
