  2. Hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Hyperparathyroidism

    In primary hyperparathyroidism, parathyroid hormone (PTH) levels are either elevated or "inappropriately normal" in the presence of elevated calcium. Typically, PTH levels vary greatly over time in the affected patient and (as with Ca and Ca++ levels) must be retested several times to see the pattern.

  3. Primary hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Primary_hyperparathyroidism

    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

  4. Parathyroid hormone - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_hormone

    Parathyroid hormone (PTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine. [5] PTH influences bone remodeling, which is an ongoing process in which bone tissue is alternately resorbed and rebuilt over

  5. Tertiary hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Tertiary_hyperparathyroidism

    Tertiary hyperparathyroidism is a condition involving the overproduction of the hormone, parathyroid hormone, produced by the parathyroid glands. [1] The parathyroid glands are involved in monitoring and regulating blood calcium levels and respond by either producing or ceasing to produce parathyroid hormone.

  6. Etelcalcetide - Wikipedia

    en.wikipedia.org/wiki/Etelcalcetide

    Etelcalcetide is used for the treatment of secondary hyperparathyroidism in people with chronic kidney disease (CKD) on hemodialysis. [7] Hyperparathyroidism is the condition of elevated parathyroid hormone (PTH) levels and is often observed in people with CKD. [8]

  7. Secondary hyperparathyroidism - Wikipedia

    en.wikipedia.org/wiki/Secondary_hyperparathyroidism

    Secondary hyperparathyroidism is the medical condition of excessive secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels), with resultant hyperplasia of these glands. This disorder is primarily seen in patients with chronic kidney failure.

  8. Hypercalcaemia - Wikipedia

    en.wikipedia.org/wiki/Hypercalcaemia

    Intact PTH (iPTH, biologically active parathyroid hormone molecules) is measured with immunoradiometric or immunochemoluminescent assay. Elevated (or high-normal) iPTH with high urine calcium/creatinine ratio (more than 0.03) is suggestive of primary hyperparathyroidism, usually accompanied by low serum phosphate.

  9. Lithium (medication) - Wikipedia

    en.wikipedia.org/wiki/Lithium_(medication)

    Lithium-associated hyperparathyroidism is the leading cause of hypercalcemia in lithium-treated patients. Lithium may lead to exacerbation of pre-existing primary hyperparathyroidism or cause an increased set-point of calcium for parathyroid hormone suppression, leading to parathyroid hyperplasia.
