Oral Peptones Load in Normocalcemic and Hypercalcemic Primary Hyperparathyroidism and Healthy Subjects
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

Medical and Biotech [MESH] Definitions
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.

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...
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...
Severe Primary hyperparathyroidism (PHP) has been associated with increased cardiovascular morbidity and mortality. Hypertension, dyslipidemia and impaired glucose tolerance were demonstra...
This 6 month long study will assess an investigational medication for patients on dialysis with secondary hyperparathyroidism. The study will look at the effects on parathyroid hormone, c...
Hyperparathyroidism is a condition with elevated parathyroid hormone (PTH). The increase may be due to a) primary hyperparathyroidism which is caused by adenoma of one or more parathyroid glands or hy...
BACKGROUND: Hyperparathyroidism is much more common in women and therefore may represent different diseases in men and women. In order to understand the role of gender in hyperparathyroidism, we revie...
Primary hyperparathyroidism is one of the most common causes of hypercalcemia. Most cases result from sporadic benign monoclonal adenomas or hyperplasia. Increased body weight is consistently present...
Summary The purpose of this study is to evaluate the effects of the number and the placement of implants on load distribution for multiple implants with three-dimensional geometric analysis, and to...
Hyperparathyroidism is present in up to 50% of transplant recipients 1 year after transplant, often despite good graft function. Posttransplant patients frequently have hypercalcemia-associated hyperp...
