OBJECTIVES: I. Identify latent hypoparathyroidism in normocalcemic adult survivors with repaired conotruncal cardiac defects, by evaluating parathyroid gland secretory function after induced hypocalcemia.
Patients are given sodium citrate over a 2 hour infusion on day 1. Blood is drawn at times -30, -15, 0, and every 10 minutes thereafter during the infusion. On day 2, patients are given calcium gluconate over a 2 hour infusion. Blood is drawn at times -30, -15, 0, and every 10 minutes thereafter during the infusion.
Primary Purpose: Screening
calcium gluconate, sodium citrate

Hypoparathyroidism is an endocrinopathy characterized by a deficient secretion or action of PTH associated with low calcium level. According to the European guideline (2015), standard trea...
Use of PTH (1-84) a recombinant hormone in escalating doses for the treatment of adults with hypoparathyroidism. The use of PTH should result in a decrease of calcium and vitamin D supple...
Long-term conventional treatment of chronic hypoparathyroidism does not fully restore calcium homeostasis leading to increased morbidity, emergency events and reduced subjective health sta...
The purpose of this study is to evaluate whether adding an investigational medication called recombinant human parathyroid hormone (rhPTH[1-84]) to standard hypoparathyroidism therapy (ora...
RATIONALE: Learning about the effect of exemestane and anastrozole on bone mineral density in postmenopausal women with primary breast cancer may help plan treatment, decrease the risk of ...
We compared two methods of calcium gluconate infusion to maintain plasma ionized calcium ([Ca ]) during therapeutic plasma exchange (TPE) performed using the Spectra Optia Apheresis System. Method A, ...
No medication has been shown to be effective at preventing recurrence of calcium phosphate urinary stones. Potassium citrate may protect against calcium phosphate stones by enhancing urine citrate exc...
Luminescent calcium fluoride (CaF) nanoparticles, because of their excellent biocompatibility, excellent photostability and strong fluorescence, have received increasing attention as drug carriers and...
Following Roux-en-Y gastric bypass (RYGB), elevated parathyroid hormone (PTH) levels potentially harmful to bone health are commonly observed. Owing to assumed superior absorption, calcium citrate is ...
This study aimed to maximise the amount of CO storage by indirect carbonation using paper sludge ash (PSA), which is an alkaline industrial waste. The properties of the following three types of solven...
Antimony complex where the metal may exist in either the pentavalent or trivalent states. The pentavalent gluconate is used in leishmaniasis. The trivalent gluconate is most frequently used in schistosomiasis.
The calcium salt of gluconic acid. The compound has a variety of uses, including its use as a calcium replenisher in hypocalcemic states.
An electrogenic ion exchange protein that maintains a steady level of calcium by removing an amount of calcium equal to that which enters the cells. It is widely distributed in most excitable membranes, including the brain and heart.
A sodium-hydrogen antiporter expressed primarily by EPITHELIAL CELLS in the kidneys, it localizes to the apical membrane of the PROXIMAL KIDNEY TUBULE, where it functions in sodium and water reabsorption and possibly calcium homeostasis. It also is expressed in heart, brain, and lung tissues and is resistant to AMILORIDE inhibition.
An enzyme that, in the presence of ATP and COENZYME A, catalyzes the cleavage of citrate to yield acetyl CoA, oxaloacetate, ADP, and ORTHOPHOSPHATE. This reaction represents an important step in fatty acid biosynthesis. This enzyme was formerly listed as EC 220.127.116.11.
Endocrine disorders are grouped into two categories: hormone imbalance - when a gland produces too much or too little of an endocrine hormone development of lesions (such as nodules or tumors) in the endocrine system, which may or may not affect...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
