Calcimimetics suppress the secretion of parathyroid hormone by sensitizing the parathyroid calcium receptor to serum calcium. Cinacalcet (Sensipar/Mimpara), Amgen Inc., Thousand Oaks, CA), the first-in-class calcimimetic agent approved for treatment of secondary hyperparathyroidism in dialysis patients, is, in association with higher dose of a calcium-based oral phosphate binder, a well-tolerated and effective alternative to standard treatments such as vitamin D derivatives in association with a non-calcium-based oral phosphate binder. Here, we present an overview of evidence in support of this assertion. We extend our discussion to encompass other indications for calcimimetics -- secondary hyperparathyroidism in predialysis chronic kidney disease patients, hypercalcemic hyperparathyroidism in renal transplant recipients, primary hyperparathyroidism, and hypercalcemia associated with parathyroid carcinoma -- as well as providing guidance on optimal usage of this drug.

Introduction: Management of secondary hyperparathyroidism (SHPT) is a challenging endeavor with several factors contruibuting to treatment failure. Calcimimetic therapy has revolutionized the management of SHPT, leading to changes in indications and appropriate timing of parathyroidectomy (PTX) around the world.

Article Synopsis
- * Without strict guidelines for treating this issue, too much parathyroid hormone can lead to serious problems like broken bones and even higher chances of death.
- * A surgical treatment called parathyroidectomy might be better than medicine, but it comes with risks, so planning for this surgery before a kidney transplant could help improve the patient's outcome.

Secondary hyperparathyroidism (SHPT) is a common complication of end-stage renal disease. Surgical management occurs in severe forms and/or unresponsive medical treatment. The aim of this study was to outline the indications of parathyroidectomy and its evolution after surgical approach.

Parathyroid disorders are most often identified incidentally by abnormalities in serum calcium levels when screening for renal or bone disease or other conditions. Parathyroid hormone, which is released by the parathyroid glands primarily in response to low calcium levels, stimulates osteoclastic bone resorption and serum calcium elevation, reduces renal calcium clearance, and stimulates intestinal calcium absorption through synthesis of 1,25-dihydroxyvitamin D. Primary hyperparathyroidism, in which calcium levels are elevated without appropriate suppression of parathyroid hormone levels, is the most common cause of hypercalcemia and is often managed surgically.

The parathyroid glands, one of the last organs to be discovered, are responsible for maintaining calcium homeostasis, and they continue to present the clinician with diagnostic and management challenges that are reviewed herein. Primary hyperparathyroidism (PHPT) comprises the vast majority of pathology of the parathyroid glands. The classic variant, presenting with elevated calcium and parathyroid hormone levels, has been studied extensively, but the current body of literature has added to our understanding of normocalcemic and normohormonal variants of PHPT, as well as syndromic forms of PHPT.
