Supporting Research There are four parathyroid glands, located behind the two lobes of the thyroid gland. The parathyroid glands produce the hormone that regulates blood levels of calcium and phosphate, minerals necessary for strong bones and teeth. Primary hyperparathyroidism is characterized by an overproduction of parathyroid hormone, which, in turn, results in an elevation of calcium levels in the blood. Signs and Symptoms At least 50% of patients with primary hyperparathyroidism have no symptoms, and approximately 1% of cases go undiagnosed. When symptoms do occur, they are generally attributable to persistently high levels of calcium and may include: What Causes It?

Extractions: *For Medical Professionals only, registration required Hyperparathyroidism, a condition in which increased levels of parathyroid hormone are found in the blood. Three types are recognized: primary, secondary and tertiary. In the primary form increased parathyroid hormone secretion occurs as a result of abnormality in one or more of the parathyroid glands, usually owing to the presence of adenoma or carcinoma. In this form the fundamental biochemical finding is persistent hypercalcaemia . The secondary form is associated with abnormalities of parathyroid gland function induced by a sustained hypocalcaemic stimulus, often resulting from chronic renal failure or malabsorption states. In this variety, renal abnormality is associated with additional soft tissue and skeletal changes, and the entire complex is termed renal osteodystrophy . Tertiary hyperparathyroidism is found in patients with chronic renal failure or malabsorption and secondary hyperparathyroidism of long duration who develop relatively autonomous parathyroid function and hypercalcaemia. The clinical features of primary and secondary hyperparathyroidism differ in some respects (Table 1).

Extractions: Hyperparathyroidism Introduction U nder normal circumstances, the blood calcium is kept within the normal range by a hormone from the parathyroid glands. There are usually four parathyroid glands (two on either side of the neck) located on the posterior aspect of the thyroid gland. The main action of parathyroid hormone (PTH) is to raise the calcium blood level by releasing calcium from the bones. Parathormone also increases the absorption of calcium through the intestinal tract and effects the amount of calcium excreted through the urine, but these are secondary functions compared to the effect on the bones. The release of PTH is controlled by the serum calcium level. When the serum calcium level falls, the PTH level rises, which, in turn releases calcium from the bones to maintain the normal blood calcium level. When the calcium blood level is elevated, the parathormorne level should be low. The most frequent cause of hypercalcemia in the United States today is hyperparathyroidism. An estimated 100,000 new cases of hyperparathyroidism are seen in this country each year. This condition occurs 3-4 times more often in females than males and increases with age. Diagnosis Today most patients with primary hyperparathyroidism are identified incidentally by a multi-channel chemical blood analysis. Symptomatology of primary hyperparathyroidism includes the five classical groups of symptoms; painful bones, kidney stones, abnormal groans, psychic moans, and fatigue overtones. Table 1 shows frequency of different symptomatology. The diagnosis of primary hyperparathyroidism depends upon; 1) repeated documentation of hypercalcemia, 2) the exclusion of external causes of hypercalcemia, (such as high doses of vitamins A or D or large amounts of calcium containing substances, 3) normal kidney function, 4) the exclusion of malignancy, and 5) parathormone (PTH) assay levels appropriately elevated in relation to concurrently determined serum calcium.

Extractions: Approximately one million people in the United States suffer from one of two forms of hyperparathyroidism (HPT). This condition results from oversecretion of parathyroid hormone (PTH) by the parathyroid glands. Primary HPT predominately affects postmenopausal women. Secondary HPT afflicts the vast majority of kidney dialysis patients. Calcimimetics may be the first safe and effective drug therapy for controlling both primary and secondary HPT. scientific publications Pharmacological regulation of parathyroid hormone secretion. The first safe and effective drug therapy for controlling both primary and secondary HPT may be provided by a class of orally active, small molecules known as calcimimetics , which were discovered by NPS Pharmaceuticals. These compounds act at calcium receptors on the surface of parathyroid cells that are known to exert direct control on the secretion of PTH. (Calcium receptors were first cloned in 1993 by NPS scientists and their collaborators at the Brigham and Women's Hospital in Boston .) In animal models and human clinical trials, calcimimetic drugs have demonstrated the ability to rapidly and significantly lower PTH levels in both primary and secondary HPT.

Extractions: New Surgical Treatment for Hyperparathyroidism Hyperparathyroidism is a hormonal condition that causes an excess of the parathyroid hormone, resulting in increased calcium levels in the blood. This condition, while showing few obvious symptoms, can put a person at a severe risk for bone loss if left untreated. Patients - typically women 50 to 60 - also can develop kidney stones, muscle weakness, fatigue and/or depression. Doctors are Franklin Square Hospital Center are utilizing a new surgical technique. The standard method to treat this condition has been to undergo a procedure that requires the patient to undergo general anesthesia while a large incision is made in the neck. Now, surgeons use a minimally invasive procedure to locate the tumor under local anesthesia. Instead of a two-day recovery n the hospital, patients goes home the same day.

Causes and Risks Hyperparathyroidism can be caused by enlargement of one or more of the parathyroid glands or in response to abnormally low calcium levels in the blood. The parathyroid glands are located at the front and base of the neck around the thyroid gland and produce parathyroid hormone . Parathyroid hormone regulates calcium, phosphorus, and magnesium balance within the blood and bone by maintaining a balance between the mineral levels in the blood and the bone. Excessive levels of parathyroid hormone disturbs this balance and results in increasing the blood calcium level by reabsorbing it from the bone and increasing absorption from the kidneys and intestines.

Self-evaluation Metabolic bone disease can result from either primary disorders of the endocrine system or, more commonly, from the reaction of the endocrine system to abnormalities in other organ systems. Although all of the endocrine organs have an effect on bone metabolism, disorders related to parathyroid gland function present the most common and significant problems. Hyperparathyroidism may be either primary, secondary or tertiary. Primary hyperparathyroidism results from a parathyroid tumor (benign or malignant) with uncontrolled ectopic production of parathyroid hormone (PTH) by the chief cells. This anomaly may be part of multiple endocrine dysfunction syndromes. The effect of elevated PTH on the target organs results in increased serum calcium, alkaline phosphatase, and PTH but decreased serum phosphate. The presence of systemic symptoms is related to the level of hypercalcemia. Secondary hyperparathyroidism, which is most commonly associated with renal disease, results from chronic

Recommendations The primary disease of parathyroid glands is overactivity, with too much parathyroid hormone (PTH) being produced. In this condition, one or more of the parathyroid glands behaves inappropriately by making excess hormone regardless of the level of calcium . In other words, the parathyroid glands continue to make large amounts of parathyroid hormone even when the calcium level is normal and they should not be making hormone at all. The most common cause of excess hormone production is the development of a benign tumor in one of the parathyroid glands. This enlargement of one parathyroid gland is called a parathyroid adenoma which accounts for 87-93% of all patients with primary hyperparathyroidism. Typically, one of the parathyroid glands has developed a tumor which is secreting all the hormone . The other three glands are small and responding appropriately to the high calcium by becoming dormant. This out of control

http://www.baptistoneword.org/healthinfo/bone Folder/hyperpar.htm

Extractions: Primary hyperparathyroidism is a metabolic disorder in which one (or more) of the parathyroid glands produces too much parathyroid hormone, which can result in the loss of bone tissue. Primary hyperparathyroidism affects 28 out of 100,000 people in the US each year, and is more prevalent in women than in men. A function of the parathyroid hormone is to keep blood-calcium levels from going too low by releasing calcium from bones, conserving calcium that would be excreted by the kidneys, and increasing calcium absorption from food. When the hormone overacts, the result is a rise in the blood-calcium level. When one parathyroid gland becomes enlarged, the condition is called adenoma. When more than one becomes enlarged, the condition is called hyperplasia. Both of these conditions are benign (non-cancerous).
