Primary hyperparathyroidism (or PHPT) is a medical condition where the parathyroid gland (or a benign tumor within it) produce excess amounts of parathyroid hormone (PTH). ). The symptoms of the condition relate to the resulting elevated serum calcium (hypercalcemia), which can cause digestive symptoms, kidney stones, psychiatric abnormalities, and bone dis
Cinacalcet, sold under the brand name Sensipar among others, is a medication used to treat primary hyperparathyroidism, tertiary hyperparathyroidism and parathyroid carcinoma. [ 4 ] [ 6 ] [ 5 ] Cinacalcet acts as a calcimimetic (i.e., it mimics the action of calcium on tissues ) by allosteric activation of the calcium-sensing receptor that is ...
Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood. [1] [4] This occurs from a disorder either within the parathyroid glands (primary hyperparathyroidism) or as response to external stimuli (secondary hyperparathyroidism). [1]
The standard of treatment of primary hyperparathyroidism was formerly a surgical technique called bilateral neck exploration, in which the neck was opened on both sides, the parathyroids were identified, and the affected tissue was removed. [12] By the 1980s, unilateral exploration became more common. [12]
Hyperparathyroidism is a condition caused by overproduction of PTH, and can be divided into three types. [citation needed] Primary hyperparathyroidism happens when the normal mechanism of regulation by negative feedback of calcium is interrupted, or in other words the amount of blood calcium would ordinarily signal less production of PTH.
Coinsurance: This is the percentage of treatment costs that a person must self-fund. For Medicare Part B, this is 20%. ... individuals with a diagnosis of primary hyperparathyroidism.
Tertiary hyperparathyroidism is defined by autonomous release of parathyroid hormone while in a hypercalcaemic state. Unlike primary hyperparathyroidism, hypercalcemia in the tertiary form is thought to be the result of resolution of secondary hyperparathyroidism rather than adenoma formation alone. [4] [11] [10]
Parathyroidectomy may also be required in secondary hyperparathyroidism. This situation arises mainly in people with severe chronic kidney disease in which the parathyroid glands are overactive to compensate for the low calcium and vitamin D levels often present in CKD. In many cases, the parathyroid hormone production improves when these ...
