Phpt cinacalcet

Polyzois Makras, Athanasios D Anastasilakis
Primary hyperparathyroidism (PHPT) is a disease of high bone turnover, decreased bone mineral density (BMD) especially at cortical sites, and increased risk of fractures at all skeletal sites. Early diagnosis during the last decades resulted in milder forms of bone involvement. New methods of imaging and validation such as high resolution peripheral quantitative computed tomography and trabecular bone score provide evidence of disturbed bone microarchitecture and explain further the increased risk of fractures at both cortical and trabecular skeletal sites...

Primary hyperparathyroidism (PHPT) is a common endocrinological process, characterized by chronic elevation of serum concentrations of calcium and parathyroid hormone (PTH). Many years ago, the most frequent forms of clinical presentation were symptomatic renal or skeletal disease with moderate or severe hypercalcemia; however, currently, most patients have few symptoms and mild hypercalcemia. A new form of presentation called normocalcemic PHPT has also been described but clinical consequences are not well established...

INTRIDUCTION: The aim of presented study was to assess the efficacy of cinacalcet in reducing serum calcium concentrations in primary hyperparathyroid (PHPT) patients with hypercalcaemia exceeding 12.5 mg/dL, awaiting parathyroidectomy. MATERIAL AND METHODS: The study included 23 patients with PHPT with hypercalcaemia > 12.5 mg/dL, qualified for surgery. We recorded clinical and biochemical data at baseline, and after every week of treatment. We also monitored adverse events...

Primary hyperparathyroidism (PHPT) is a disease involving a broad range of alterations of calcium homeostasis, sustained by parathyroid hormone (PTH) levels that are clearly abnormal. The anomalies directly associated with hyperparathyroidism are nephrolithiasis and fibrocystic bone disease. Since PHPT resolves when abnormal parathyroid tissue is removed, surgery is clearly the only definitive approach to this type of hyperparathyroidism. However there are large subgroups of patients for whom medical therapy should be considered instead of surgery...

Pharmacological treatment of hypercalcemia is essential for patients with parathyroid carcinoma and intractable primary hyperparathyroidism (PHPT). Use of the calcimimetic cinacalcet hydrochloride (cinacalcet) is an option to treat such patients. We investigated the efficacy and safety of cinacalcet in Japanese patients with parathyroid carcinoma and intractable PHPT. Five Japanese patients with parathyroid carcinoma and two with intractable PHPT were enrolled in an open-label, single-arm study consisting of titration and maintenance phases...

Primary hyperparathyroidism (PHPT) may favor nephrolithiasis mainly through an increase in calcium and phosphate urinary excretion. Cinacalcet exhibits good efficacy to control hypercalcemia in PHPT, but it is not so far known whether it might be a useful tool to prevent stone recurrences. Of 67 patients with PHPT and recurrent nephrolithiasis, 55 underwent parathyroidectomy (PTX) and 12, not eligible to PTX, were prescribed Cinacalcet. All the patients were evaluated for mineral metabolism, including estimation of state of saturation for calcium oxalate (CaOx) and brushite (bsh), both at baseline and after either PTX or Cinacalcet...

OBJECTIVE: High parathyroid hormone (PTH) is a cardiovascular risk factor. Elevated plasma PTH levels are independently linked with high nighttime blood pressure (BP) in hypertensive patients. We therefore investigated the association between PTH and nighttime BP in patients with primary hyperparathyroidism (pHPT). DESIGN AND METHOD: We analyzed patients with pHPT who participated in the "Eplerenone in Primary Hyperparathyroidism" (EPATH) Trial. Blood sampling was performed after an overnight fast and all laboratory parameters were determined immediately after blood sampling...

Parathyroid tumors are almost invariably associated with parathormone (PTH) hypersecretion resulting in primary (PHPT) or secondary (SHPT) hyperparathyroidism. PHPT is the third most common endocrine disorder with a prevalence of 1-2% in post-menopausal women; SHPT is a major complication of chronic kidney failure, the prevalence of which is increasing. The calciumsensing receptor (CASR) is the key molecule regulating PTH synthesis and release from the parathyroid cells in response to changes in extracellular calcium concentrations...

OBJECTIVE: A calcium load to suppress parathyroid hormone (PTH) secretion can help to perform the diagnosis in some case of primary hyperparathyroidism (PHPT) with atypical presentation. A similar test with calcimimetic, which avoids hypercalcaemia, would be of interest. Our proof of concept study was conducted to compare firstly the results of a single-dose cinacalcet testing with those of the standardized short-time calcium load in healthy control (HC) and secondly the results of the single-dose cinacalcet testing in HC and in PHPT...

OBJECTIVE: Primary hyperparathyroidism (PHPT) is diagnosed by the presence of hypercalcemia and elevated or nonsuppressed parathyroid hormone (PTH) levels. Although surgery is usually curative, some individuals fail or are unable or unwilling to undergo parathyroidectomy. In such individuals, targeted medical therapy may be of value. Cinacalcet normalized calcium level and lowered PTH in patients with PHPT in several phase 2 and open-label studies. We compared cinacalcet and placebo in subjects with PHPT unable to undergo parathyroidectomy...

BACKGROUND: Primary hyperparathyroidism (PHPT) is often found on routine blood tests, at a relatively asymptomatic stage. However many studies suggest different systemic effects related to PHPT, which could be enhanced by an abnormal cortisol release due to chronic stress of hyperparathyroidism. Being PHPT frequently found in the 6(th) to 7(th) decade of life, a careful and multifaceted approach should be taken. CASE PRESENTATION: We report the case of an elderly patient with symptomatic PHPT and incidental pulmonary embolism...

Today, primary hyperparathyroidism (PHPT) is frequently diagnosed at an asymptomatic stage. New international guidelines presented at the Endocrine Society congress update the management of this disease. Normocalcemic PHPT is part of the diagnostic spectrum of PHPT, its natural history is poorly known, and monitoring is proposed once secondary HPT has been eliminated. Bone involvement, classically predominant in cortical bone, also affects trabecular bone. Osteodensitometry is poorly effective at the vertebral level and new methods (trabecular bone score [TBS], vertebral fracture assessment [VFA]) should improve the assessment of the risk of fracture...

Primary hyperparathyroidism (PHPT) is a biochemical syndrome caused by the inappropriate or unregulated overproduction of parathyroid hormone, Leading to hypercalcae-mia. It was previously considered a relatively rare disorder, with clinical manifestations dominated by renal and/or bone disease. However, in modern times the diagnosis is most frequently recognized coincidentally on biochemical testing in patients evaluated for unrelated complaints. Parathyroidectomy is the only curative treatment for PHPT, with improved outcomes in symptomatic patients following this procedure...
