Hyperparathyroidism In hyperparathyroidism the parathyroid hormone (PTH) level is elevated, the number of osteoblasts is markedly increased, and the bones become porous. In hyperparathyroidism BMD values can differ very much per bone, and some BMD values can even be elevated due to increased osteoblast activity. So what exact influence has PTH on the bones? PTH stimulates uptake of calcium into the bones, osteoblast apoptosis and deportation of calcium from the bones. This is exactly the opposite of the influence of estrogen, and since estrogen is protective, excessive PTH logically accelerates osteoporosis. Estrogen and PTH do not just have opposite effects on bone; estrogen also prevents the PTH level from increasing too much. When estrogen level is at its lowest (around menstruation and after menopause), PTH level is at its highest. That is why hyperparathyroidism is common in postmenopausal women and estrogen administration is an effective therapy. If a lack of estrogen caused the hyperparathyroidism, parathyroidectomy does not result in complete bone-reparation, of course. Besides estrogen, calcitriol also inhibits PTH secretion. Though calcitriol has similar, but less strong effects on bones, supplementary calcitriol can per saldo strongly decrease uptake of calcium into the bones and deportation from the bones

Feedback Introduction: Hyperparathyroidism Hyperparathyroidism: Hyperparathyroidism refers to an excess secretion of hormones by the parathyroid glands , and this alters calcium metabolism. Hyperparathyroidism: If the glands secrete too much hormone, as in hyperparathyroidism, the balance is disrupted: blood calcium rises. This condition of excessive calcium in the blood, called hypercalcemia, is what usually signals the doctor that something may be wrong with the parathyroid glands.

Treatment recommendations Most people with primary hyperparathyroidism have one or more enlarged, overactive parathyroid glands that secrete too much parathyroid hormone . In secondary hyperparathyroidism, a problem such as kidney failure makes the body resistant to the action of parathyroid hormone . Here we deal mainly with primary hyperparathyroidism, which develops in about 100,000 people in the U.S. each year. The parathyroid glands are normally located on the thyroid gland in the neck. Occasionally, a person is born with one or more of the parathyroid glands embedded in the thyroid , the thymus , or somewhere in the chest. In most such cases, however, the glands function normally. Although their names are similar, the thyroid and parathyroid glands are entirely separate glands, each producing distinct hormones with specific functions.

Resources Definition Parathyroid glands are four pea-sized glands located just behind the thyroid gland in the front of the neck. The function of parathyroid glands is to produce a hormone called parathyroid hormone (parathormone), which helps regulate calcium and phosphorous in the body. Hyperparathyroidism is the overproduction of this hormone. Description Thyroid glands and parathyroid glands, despite their similar name and proximity, are entirely separate, and each produces hormones with different functions. Hyperparathyroidism may be primary or secondary. It most often occurs in those over age 30, and most commonly in patients 50 to 60 years old. It rarely occurs in children or the elderly. Women are affected by the disease up to three times more often than men. It is estimated that 28 of every 100,000 people in the United States will develop hyperparathyroidism each year. Normally, parathyroid glands produce the parathormone as calcium levels drop and lower to meet the demands of a growing skeleton, pregnancy , or lactation . However, when one or more parathyroid glands malfunctions, it can lead to overproduction of the hormone and elevated calcium level in the blood. Therefore, a common result of hyperparathyroidism is

Go To Main Page Definition Hyperparathyroidism is excessive production of parathyroid hormone by the parathyroid glands. Parathyroid Glands The parathyroid glands are located at the front and base of the neck around the thyroid gland. They produce parathyroid hormone , which regulates calcium, phosphorus, and magnesium levels within the blood and bone. When calcium levels are too low, the body responds by increasing production of parathyroid hormone. This increase in parathyroid hormone causes more calcium to be taken from the bone and more calcium to be reabsorbed by the intestines and kidney. When the cacium level returns to normal, parathyroid hormone production slows down. Excess parathyroid hormone can be produced for a variety of reasons. In some cases, parathyroid hormone is produced without regard to the calcium levels. This is called "primary hyperparathyroidism" and is caused by enlargement of one or more of the parathyroid glands. It is a common disorder affecting about 1 in 1000 people. The high levels of calcium and parathyroid hormone affect several body systems, including the skeletal, gastrointestinal

Chapters at Harrison's ABSTRACT Background Treatment of secondary hyperparathyroidism with vitamin D and calcium in patients receiving dialysis is often complicated by hypercalcemia and hyperphosphatemia, which may contribute to cardiovascular disease and adverse clinical outcomes. Calcimimetics target the calcium-sensing receptor and lower parathyroid hormone levels without increasing calcium and phosphorus levels. We report the results of two identical randomized, double-blind, placebo-controlled trials evaluating the safety and effectiveness of the calcimimetic agent cinacalcet hydrochloride. Methods Patients who were receiving hemodialysis and who had inadequately controlled secondary hyperparathyroidism despite standard treatment were randomly assigned to receive cinacalcet (371 patients) or placebo (370 patients) for 26 weeks.

Other characters 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). Hyperparathyroidism, Table 1. Primary versus secondary hyperparathyroidism.

Amershamhealth.com Search for: Type a word or a phrase. All forms of the word are searchable. Browse entry words starting with: A B C D ... Other characters Hyperparathyroidism, primary, a condition resulting from increased secretion of parathormone and very rare in childhood. The aetiology is unknown but cases may be sporadic, nearly always associated with a solitary adenoma, rarely with carcinoma, or familial (usually due to hyperplasia of all 4 glands). Familial cases may also be associated with the autosomal dominant multiple endocrine neoplasia (MEN) syndromes. The clinical spectrum of primary hyperparathyroidism ranges from being virtually asymptomatic to causing great morbidity and death if untreated. Symptoms include fatigue, anorexia, constipation, polyuria, polydipsia, renal stones, bone pain and pathological fractures. Diagnosis depends on the demonstration of inappropriately high parathormone levels for the hypercalcaemia on three separate occasions. The commonest manifestation of primary hyperparathyroidism is nephrolithiasis. Radiological evidence of bone disease occurs in less than 20% of cases in children. There may be absence of lamina dura around the teeth. More specific is subperiosteal resorption of bone, especially around the radial margins of the phalanges, the sternal end of the clavicle and around the margins of other long bones. Diffuse "salt and pepper" decalcification of the skull is sometimes present. There may be diffuse demineralisation of the skeleton with cod-fish appearance of the vertebral bodies. Bone cysts (osteoblastomas) and giant cell tumours of the jaws may be presenting features.
