The purpose of this study is to assess if subjects with hyperparathyroidism with normal serum calcium levels have different responses in the calcium regulating hormonal handling compared to a) patients with primary hyperparathyroidism and high serum calcium levels; b) healthy subjects.
The differences will be evaluated with oral peptones load and subsequent blood samples collected every 15 minutes for two hours. Ionized calcium, phosphate, gastrin and PTH levels will be evaluated.
Control: Active Control, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Basic Science

The purpose of this study is to determine whether oral paricalcitol is safer and more efficacious compared to oral calcitriol in the treatment of hyperparathyroidism in chronic kidney dise...
There are still no established protocols for maintenance therapy with intravenous or oral vitamin D preparations after the iPTH target has been achieved. Therefore, the present study comp...
To assess the efficiency of 18F-fluorocholine PET/CT in localization of hyperfunctioning parathyroid tissue in hyperparathyroidism, thereby enabling minimally invasive surgical approaches ...
This is a research study to investigate cardiovascular health in people with mild hyperparathyroidism. Previous research has suggested that severe hyperparathyroidism may be associated wit...
This study will evaluate whether blocking the mineralocorticoid receptor, alone, or in combination with the calcimimetic cinacalcet, can lower parathyroid hormone and calcium levels in pri...
Hyperparathyroidism is a common endocrine disorder. Parathyroidectomy is indicated for primary and tertiary hyperparathyroidism. Parathyroid adenoma is the cause in close to 85% of cases of primary hy...
The clinical significance of measuring central arterial blood pressure has been recently discussed. Although the postprandial reduction in blood pressure is well known, postprandial changes in central...
Arterial stiffness is linked to the progression of atherosclerosis, while activation of vitamin D receptor exerts favorable cardiovascular effects in patients with renal insufficiency. In this study, ...
Hyperparathyroidism is associated with hypercalcemia and the excess of parathyroid hormone secretion. However, the alterations in molecular pattern of functional genes during parathyroid tumorigenesis...
The multi-phase or four-dimensional computed tomography (4D CT) has emerged as a promising technique for preoperative localization of parathyroid lesions in patients with primary hyperparathyroidism (...
Derived proteins or mixtures of cleavage products produced by the partial hydrolysis of a native protein either by an acid or by an enzyme. Peptones are readily soluble in water, and are not precipitable by heat, by alkalis, or by saturation with ammonium sulfate. (Dorland, 28th ed)
A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
The quantity of measurable virus in a body fluid. Change in viral load, measured in plasma, is sometimes used as a SURROGATE MARKER in disease progression.
An inhibitor of alpha glucosidase that retards the digestion and absorption of carbohydrates in the small intestine and hence reduces the increase in blood-glucose concentrations after a carbohydrate load. It is given orally to non-insulin dependent diabetes mellitus patients where diet modification or oral hypoglycemic agents do not control their condition. (From Martindale The Extra Pharmacopoeia, 31st ed)
A branch of dentistry dealing with diseases of the oral and paraoral structures and the oral management of systemic diseases. (Hall, What is Oral Medicine, Anyway? Clinical Update: National Naval Dental Center, March 1991, p7-8)
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...
