BACKGROUND: Secondary Hyperparathyroidism (SHPT) requiring parathyroidectomy (PTX) occurs more commonly in patients with progressive chronic kidney disease and in those on long-term lithium therapy. Successful PTX often results in a dramatic drop of parathyroid hormone level, relieves the patient from clinical symptoms, and reduces mortality. However, there is an ongoing debate on the optimal surgical treatment of SHPT. Currently, no clinical guidelines or trials have definitely answered the question of whether Total Parathyroidectomy (TPTX) is superior or equal to Total Parathyroidectomy with Autotransplantation (TPTX + AT)...

N-terminal propeptide of type I procollagen and C-terminal telopeptide of type I collagen are the reference standards for bone turnover markers for monitoring osteoporosis treatment. We provide recommendations for standardized sample handling and encompassing aspects of preanalytical variability to improve the reproductibility of their measurements, their reliability, and clinical interpretation. The International Osteoporosis Foundation and International Federation of Clinical Chemistry bone turnover marker standards working group have identified N-terminal propeptide of type I procollagen (PINP) and C-terminal telopeptide of type I collagen (CTX-I) in the blood to be the international reference standards for bone turnover markers for the prediction of fracture risk and monitoring of osteoporosis treatment...

BACKGROUND AND OBJECTIVES: Paricalcitol, a selective vitamin D receptor activator, is used to treat secondary hyperparathyroidism in kidney transplant patients. Experimental and clinical studies in non-transplant kidney disease patients have found this molecule to have anti-inflammatory properties. In this exploratory study, we evaluated the anti-inflammatory profile of paricalcitol in kidney-transplant recipients. METHODS: Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1μg/day)...

CONTEXT AND OBJECTIVE: Detailed information on the epidemiology of parathyroid disorders in India is lacking. Most of the available data pertain to primary hyperparathyroidism (PHPT) rather than the overall burden of parathyroid disorders. We studied the incidence of parathyroid disorders in a cohort of service personnel followed for a long duration. DESIGN, SETTING AND PATIENTS: The data for this retrospective, descriptive epidemiological study were derived from the electronic medical records (EMR) of health care personnel enrolled between 1990 and 2015...

Secondary hyperparathyroidism (SHPT), a very frequent, severe, and worsening complication of chronic kidney disease, is characterized by high serum parathyroid hormone (PTH), parathyroid gland hyperplasia, and disturbances in mineral metabolism. Clinically, SHPT shows renal osteodystrophy, vascular calcification, cardiovascular damage, and fatal outcome. Calcium-sensing receptor (CaSR) is the main physiological regulator of PTH secretion; its activation by calcium rapidly inhibits PTH. Another important player in regulating mineral metabolism is vitamin D receptor (VDR), which is under the influence of vitamin D and influences the intestinal absorption of calcium and phosphate, PTH gene expression, and bone calcium mobilization...

Parathyroid surgery has undergone great changes since its inception less than a century ago. It is still the only definitive option available to cure primary or tertiary hyperparathyroidism. This review details the development of parathyroid surgery, our understanding of hyperparathyroidism and the treatment options available. It also discusses the technological advances that have enabled parathyroid localization and prediction of surgical success.

Sporadic carcinoma of the parathyroid glands is a rare malignant neoplasia. The GCM2 gene encodes a transcription factor that is crucial to embryonic parathyroid development. The Y282D variant of GCM2 exhibits increased transcriptional activity, and the presence of this variant is significantly associated with a higher prevalence of primitive hyperparathyroidism. The present study investigated the prevalence of the Y282D variant of the GCM2 gene and its association with clinical parameters in patients with a definitive histological diagnosis of sporadic parathyroid carcinoma (SPC) or atypical adenoma (AA)...

The vitamin D receptor (VDR) mediates the pleiotropic biological actions of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3). These actions include orchestration of mineral homeostasis which is coordinated by the kidney, intestine, bone and parathyroid gland wherein the VDR transcriptionally regulates expression of the genes involved in this complex process. Mutations in human VDR (hVDR) cause hereditary vitamin D resistant rickets, a genetic syndrome characterized by hypocalcemia, hyperparathyroidism and rickets resulting from dysregulation of mineral homeostasis...

Hypercalcemia is a rare metabolic disorder associated with hyperparathyroidism, malignancy and various other causes. Although common in adult malignancies, hypercalcemia is rare in pediatrics and purports poor prognosis. Nasopharyngeal carcinoma is rare with no reported hypercalcemic presentation. We present here a case of hypercalcemia in a child of nasopharyngeal carcinoma. A 10 year girl presented with backache for 1 month, epistaxis, cough, chest-pain for 1 week alongwith anorexia and weight loss. Investigations revealed anemia and hypercalcemia (23mg/dl; normal range 9-11 mg/dl) with hyperphosphatemia, normal parathyroid levels...

Inherited, germline mutations of menin-coding MEN1 gene cause multiple endocrine neoplasia type 1 (MEN1), while somatic MEN1 mutations are the sole main driver mutations in sporadic primary hyperparathyroidism (PHPT), suggesting that menin deficiency has a central role in the pathogenesis of PHPT. MiRNAs are small, noncoding RNAs posttranscriptionally regulating gene expression. Our aim was to investigate both the role of MEN1 mutations and potentially MEN1-targeting miRNAs as the underlying cause of menin deficiency in MEN1-associated and sporadic PHPT tissues...

BACKGROUND: The inappropriate elevation of parathormone (PTH), which regulates the process of angiogenesis in parathyroid tissue, causes the changes of activity of enzymes responsible for the removal of free radicals. Parathyroidectomy (PTX) in patients with primary hyperparathyroidism (PHPT) lowers the level of PTH and leads to the reduction of risk of cardiovascular and all-cause mortality by normalization of the antioxidant status. Therefore, the aims of the study were to assess the activity of antioxidant enzymes and free radical reaction products in patients after parathyroidectomy, and to evaluate the correlation between the systemic oxidative stress and angiogenic parameters...

Bladder stones are caused when minerals are built up in the bladder, especially if the bladder is incompletely emptied. These stones will pass while they are small. Otherwise, they get stuck to the bladder wall or ureter. If this happens, they gradually gather more mineral crystals, becoming larger over time. Primary hyperparathyroidism is usually caused by a tumor within the parathyroid gland, and elevated calcium levels can cause digestive symptoms, psychiatric abnormalities, bone disease and multiple kidney stones...
