Abnormally high level of calcium in the blood.
A ubiquitously expressed, secreted protein with bone resorption and renal calcium reabsorption activities that are similar to PARATHYROID HORMONE. It does not circulate in appreciable amounts in normal subjects, but rather exerts its biological actions locally. Overexpression of parathyroid hormone-related protein by tumor cells results in humoral calcemia of malignancy.
A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.
A class of G-protein-coupled receptors that react to varying extracellular CALCIUM levels. Calcium-sensing receptors in the PARATHYROID GLANDS play an important role in the maintenance of calcium HOMEOSTASIS by regulating the release of PARATHYROID HORMONE. They differ from INTRACELLULAR CALCIUM-SENSING PROTEINS which sense intracellular calcium levels.
Syndromes resulting from inappropriate production of HORMONES or hormone-like materials by NEOPLASMS in non-endocrine tissues or not by the usual ENDOCRINE GLANDS. Such hormone outputs are called ectopic hormone (HORMONES, ECTOPIC) secretion.
Tumors or cancer of the PARATHYROID GLANDS.
Reduction of the blood calcium below normal. Manifestations include hyperactive deep tendon reflexes, Chvostek's sign, muscle and abdominal cramps, and carpopedal spasm. (Dorland, 27th ed)
Excision of one or more of the parathyroid glands.
Organic compounds which contain P-C-P bonds, where P stands for phosphonates or phosphonic acids. These compounds affect calcium metabolism.

A condition of abnormally elevated output of PARATHYROID HORMONE due to parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. It is characterized by the combination of HYPERCALCEMIA, phosphaturia, elevated renal 1,25-DIHYDROXYVITAMIN D3 synthesis, and increased BONE RESORPTION.
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
Two pairs of small oval-shaped glands located in the front and the base of the NECK and adjacent to the two lobes of THYROID GLAND. They secrete PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.
The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (CALCIFEDIOL). Its production is stimulated by low blood calcium levels and parathyroid hormone. Calcitriol increases intestinal absorption of calcium and phosphorus, and in concert with parathyroid hormone increases bone resorption.
A VITAMIN D that can be regarded as a reduction product of vitamin D2.
In patients with neoplastic diseases a wide variety of clinical pictures which are indirect and usually remote effects produced by tumor cell metabolites or other products.
Bone loss due to osteoclastic activity.

A rare, metallic element designated by the symbol, Ga, atomic number 31, and atomic weight 69.72.
Pathological processes of the PARATHYROID GLANDS. They usually manifest as hypersecretion or hyposecretion of PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.
A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.
A condition caused by a deficiency of PARATHYROID HORMONE (or PTH). It is characterized by HYPOCALCEMIA and hyperphosphatemia. Hypocalcemia leads to TETANY. The acquired form is due to removal or injuries to the PARATHYROID GLANDS. The congenital form is due to mutations of genes, such as TBX1; (see DIGEORGE SYNDROME); CASR encoding CALCIUM-SENSING RECEPTOR; or PTH encoding parathyroid hormone.
A condition in which the death of adipose tissue results in neutral fats being split into fatty acids and glycerol.
A peptide hormone that lowers calcium concentration in the blood. In humans, it is released by thyroid cells and acts to decrease the formation and absorptive activity of osteoclasts. Its role in regulating plasma calcium is much greater in children and in certain diseases than in normal adults.
An idiopathic systemic inflammatory granulomatous disorder comprised of epithelioid and multinucleated giant cells with little necrosis. It usually invades the lungs with fibrosis and may also involve lymph nodes, skin, liver, spleen, eyes, phalangeal bones, and parotid glands.
Benign and malignant tumors of the HYPOTHALAMUS. Pilocytic astrocytomas and hamartomas are relatively frequent histologic types. Neoplasms of the hypothalamus frequently originate from adjacent structures, including the OPTIC CHIASM, optic nerve (see OPTIC NERVE NEOPLASMS), and pituitary gland (see PITUITARY NEOPLASMS). Relatively frequent clinical manifestations include visual loss, developmental delay, macrocephaly, and precocious puberty.

A condition characterized by calcification of the renal tissue itself. It is usually seen in distal RENAL TUBULAR ACIDOSIS with calcium deposition in the DISTAL KIDNEY TUBULES and the surrounding interstitium. Nephrocalcinosis causes RENAL INSUFFICIENCY.
Disorders in the processing of calcium in the body: its absorption, transport, storage, and utilization.
Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.
A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.

22-oxacalcitriol suppresses secondary hyperparathyroidism without inducing low bone turnover in dogs with renal failure. (1/967)

BACKGROUND: Calcitriol therapy suppresses serum levels of parathyroid hormone (PTH) in patients with renal failure but has several drawbacks, including hypercalcemia and/or marked suppression of bone turnover, which may lead to adynamic bone disease. A new vitamin D analogue, 22-oxacalcitriol (OCT), has been shown to have promising characteristics. This study was undertaken to determine the effects of OCT on serum PTH levels and bone turnover in states of normal or impaired renal function. METHODS: Sixty dogs were either nephrectomized (Nx, N = 38) or sham-operated (Sham, N = 22). The animals received supplemental phosphate to enhance PTH secretion. Fourteen weeks after the start of phosphate supplementation, half of the Nx and Sham dogs received doses of OCT (three times per week); the other half were given vehicle for 60 weeks. Thereafter, the treatment modalities for a subset of animals were crossed over for an additional eight months. Biochemical and hormonal indices of calcium and bone metabolism were measured throughout the study, and bone biopsies were done at baseline, 60 weeks after OCT or vehicle treatment, and at the end of the crossover period. RESULTS: In Nx dogs, OCT significantly decreased serum PTH levels soon after the induction of renal insufficiency. In long-standing secondary hyperparathyroidism, OCT (0.03 microg/kg) stabilized serum PTH levels during the first months. Serum PTH levels rose thereafter, but the rise was less pronounced compared with baseline than the rise seen in Nx control. These effects were accompanied by episodes of hypercalcemia and hyperphosphatemia. In animals with normal renal function, OCT induced a transient decrease in serum PTH levels at a dose of 0.1 microg/kg, which was not sustained with lowering of the doses. In Nx dogs, OCT reversed abnormal bone formation, such as woven osteoid and fibrosis, but did not significantly alter the level of bone turnover. In addition, OCT improved mineralization lag time, (that is, the rate at which osteoid mineralizes) in both Nx and Sham dogs. CONCLUSIONS: These results indicate that even though OCT does not completely prevent the occurrence of hypercalcemia in experimental dogs with renal insufficiency, it may be of use in the management of secondary hyperparathyroidism because it does not induce low bone turnover and, therefore, does not increase the risk of adynamic bone disease.  (+info)

The elevated serum alkaline phosphatase--the chase that led to two endocrinopathies and one possible unifying diagnosis. (2/967)

A 39-year-old Chinese man with hypertension being evaluated for elevated serum alkaline phosphatase (SAP) levels was found to have an incidental right adrenal mass. The radiological features were characteristic of a large adrenal myelolipoma. This mass was resected and the diagnosis confirmed pathologically. His blood pressure normalised after removal of the myelolipoma, suggesting that the frequently observed association between myelolipomas and hypertension may not be entirely coincidental. Persistent elevation of the SAP levels and the discovery of hypercalcaemia after surgery led to further investigations which confirmed primary hyperparathyroidism due to a parathyroid adenoma. The patient's serum biochemistry normalised after removal of the adenoma. The association of adrenal myelolipoma with primary hyperparathyroidism has been reported in the literature only once previously. Although unconfirmed by genetic studies this association may possibly represent an unusual variation of the multiple endocrine neoplasia type 1 syndrome.  (+info)

Pamidronate reduces skeletal morbidity in women with advanced breast cancer and lytic bone lesions: a randomized, placebo-controlled trial. Protocol 18 Aredia Breast Cancer Study Group. (3/967)

PURPOSE: To assess whether pamidronate can reduce the frequency of skeletal morbidity in women with lytic bone metastases from breast cancer treated with hormone therapy. PATIENTS AND METHODS: Three hundred seventy-two women with breast cancer who had at least one lytic bone lesion and who were receiving hormonal therapy were randomized to receive 90 mg of pamidronate or placebo as a 2-hour intravenous infusion given in double-blind fashion every 4 weeks for 24 cycles. Patients were evaluated for skeletal complications: pathologic fractures, spinal cord compression, irradiation of or surgery on bone, or hypercalcemia. The skeletal morbidity rate (the ratio of the number of skeletal complications to the time on trial) was the primary efficacy variable. Bone pain, use of analgesics, quality of life, performance status, bone tumor response, and biochemical parameters were also evaluated. RESULTS: One hundred eighty-two patients who received pamidronate and 189 who received placebo were assessable. The skeletal morbidity rate was significantly reduced at 12, 18, and 24 cycles in patients treated with 90 mg of pamidronate (P = .028, .023, and .008, respectively). At 24 cycles, the proportion of patients having had any skeletal complication was 56% in the pamidronate group and 67% in the placebo group (P = .027). The time to the first skeletal complication was longer for patients receiving pamidronate than for those given placebo (P = .049). There was no statistical difference in survival or in objective bone response rate. Pamidronate was well tolerated. CONCLUSION: Treatment with 90 mg of pamidronate as a 2-hour intravenous infusion every 4 weeks in addition to hormonal therapy significantly reduces skeletal morbidity from osteolytic metastases.  (+info)

Inhibition of prostate cancer metastasis in vivo: a comparison of 1,23-dihydroxyvitamin D (calcitriol) and EB1089. (4/967)

The steroid hormone 1,25-dihydroxyvitamin D [1,25(OH)2D, also known as calcitriol] is known to inhibit the proliferation and to promote the differentiation of human prostate cancer cells. Additionally, we showed that 1,25(OH)2D markedly inhibits the invasiveness of human prostate cancer cells in vitro (G. G. Schwartz et al., Cancer Epidemiol. Biomark. Prev., 6: 727-732, 1997). These properties support the use of 1,25(OH)2D as differentiation therapy in prostate cancer. However, the use of 1,25(OH)2D in vivo is limited by the risk of hypercalcemia. We therefore compared the effects of 1,25(OH)2D and of EB1089, an analogue of 1,25(OH)2D with reduced calcemic effects, in an in vivo model of androgen-insensitive metastatic prostate cancer, the rat Dunning MAT LyLu prostate cancer model. Tumor growth and metastasis were studied using Copenhagen rats given s.c. injections of MAT LyLu cells. Fifty male rats were divided into five groups of 10 rats each. Four experimental groups received i.p. injections of low and high doses of 1,25(OH)2D and EB1089 (0.5 and 1.0 microg/kg, low and high, respectively). A control group received injections of vehicle only. Tumor volumes were measured three times per week. Rats were weighed weekly. The number of metastases to the lungs and the extent of hypercalcemia were evaluated. Compared with controls, tumor volumes were significantly smaller in all experimental groups. Similarly, the number of lung metastases (number of foci/lung) was reduced markedly by both 1,25(OH)2D and EB1089. Control rats developed 22.7 (+/- 1.98 SE) tumor foci per lung. Rats treated with 1,25(OH)2D and with EB1089 (1.0 microg/kg) developed 10.4 (+/- 2.81) and 7.70 (+/- 1.29) tumor foci, respectively (P < 0.001 and P < 0.0001, respectively; drug versus control). Compared with controls (10.79 +/- 0.1 mg/dl), serum calcium levels were significantly elevated in both 1,25(OH)2D and EB1089-treated rats (P < 0.01). However, EB1089 was significantly less calcemic than 1,25(OH)2D (12.59 +/- 0.21 mg/dl versus 14.47 +/- 0.46 mg/dl; 1.0 microg/kg; P < 0.001). Rats treated with 1,25(OH)2D showed marked weight loss: 20.0 +/- 1.9% and 26.3 +/- 1.7% of their initial weight (low and high doses, respectively, P < 0.001). Weight loss was significantly lower in rats treated with EB1089 at the high dose 8.4 (+/- 2.9) %. Moreover, rats treated with low-dose EB1089 gained 5.2 (+/- 3.7) % of their initial weight. In conclusion, 1,25(OH)2D and EB1089 showed marked and equivalent inhibition of prostate cancer metastasis in vivo. EB1089 was significantly less calcemic than 1,25(OH)2D and did not induce severe weight loss. This is the first report of a vitamin D analogue that significantly inhibits prostate cancer metastasis in vivo and that does so without producing cachexia or unacceptable hypercalcemia.  (+info)

Renal biopsy in the milk-alkali syndrome. (5/967)

In milk-alkali syndrome the degree of renal impairment varies greatly. Few reports have been published describing structural changes on renal biopsy. In three illustrative cases, impairment of renal function was related to morphological changes shown on percutaneous biopsy. Milk-alkali syndrome should be considered as a cause of renal dysfunction in patients with a long history of dyspensia.  (+info)

A large intrathoracic parathyroid adenoma. (6/967)

A case is described in which an unusually large parathyroid adenoma was visible on the plain chest radiograph taken during the investigation of hypercalcaemia. This was diagnosed preoperatively and a scheme is suggested whereby such a disgnosis can now readily be made. The differential diagnosis is discussed ant the literature is reviewed.  (+info)

Promoter structure of mouse RANKL/TRANCE/OPGL/ODF gene. (7/967)

Receptor activator of NF-kappa B ligand (RANKL)/tumor necrosis factor-related activation induced cytokine (TRANCE)/osteoprotegerin ligand (OPGL)/osteoclast differentiation factor (ODF) is a membrane-bound signal transducer responsible for differentiation and maintenance of osteoclasts. To elucidate the mechanism regulating RANKL/TRANCE/OPGL/ODF gene expression, we cloned the 5'-flanking basic promoter region of the mouse RANKL/TRANCE/OPGL/ODF gene and characterized it by transient transfection studies and genomic Southern blot analysis. Inverted TATA- and CAAT-boxes and a putative Cbfa1/Osf2/AML3 binding domain constituted the basic promoter structure. The repeated half-sites for the vitamin D3 (VitD3) and glucocorticoid receptors were located at -935 and -640, respectively. Transient transfection studies revealed that short-term treatment with 1alpha,25(OH)2 VitD3 or dexamethasone increased luciferase activity up to 204% and 178%, respectively; on the other hand, treatment with dibutyryl cyclic AMP did not affect the promoter activity. Since the expression of Cbfa1/Osf2/AML3 is also regulated by VitD3, 1alpha,25(OH)2 VitD3 might affect RANKL/TRANCE/OPGL/ODF gene expression both directly and indirectly. CpG methylation was observed dominantly in mouse stromal cells, ST2, of a later passage which ceased to support in vitro osteoclastogenesis, suggesting that the methylation status of the CpG loci in the RANKL/TRANCE/OPGL/ODF gene promoter may be one of the influential cis-regulating factors.  (+info)

Excessive Ca and P intake during early maturation in dogs alters Ca and P balance without long-term effects after dietary normalization. (8/967)

Calcium (Ca) and phosphorus (P) balance is important for skeletal development. Although the effects of deficiencies are well known, reports on the effects of excessive Ca and P supply are relatively scarce. Epidemiologic data and a few controlled studies have shown that skeletal abnormalities may develop when Ca intake is excessive, particularly in periods of rapid growth. Changes in Ca and P balance during and/or after a high Ca intake are thought to underlie this phenomenon. In this study, the effects of excessive Ca (3.1 g/kg dry matter) or Ca and P (Ca 3.1 g/kg, P 2.8 g/kg) intake on Ca and P balance in young, rapidly growing dogs during (for the period from 3 to 17 wk of age) and after (for the period from 17 to 27 wk of age) high Ca and P intake were compared with findings in age-matched controls with normal Ca and P intakes (Ca 1.0 g/kg, P 0.8 g/kg). Dogs fed a high Ca diet developed hypercalcemia, and food intake and fractional absorption of Ca and P were significantly lower at 15 wk of age, whereas endogenous fecal and renal Ca excretion were significantly higher than in controls. This resulted in significantly higher Ca retention than in controls only at 9 wk of age, and in disproportionate absorption of Ca and P. In dogs fed a high Ca and P diet, normocalcemia was maintained, fractional absorption of Ca and P were significantly lower at 9 and 15 wk of age, but retention of both was significantly higher at 9 wk than in controls. The endogenous fecal Ca and renal P losses were significantly higher, but renal Ca excretion was not different from that in controls. After normalization of Ca and P intake, Ca and P balance did not differ among groups. In conclusion, excessive Ca and P intake during early maturation alters Ca and P balance, but does not influence Ca and P balance after dietary normalization.  (+info)

Management of malignancy-associated hypercalcemia is usually guided by the severity of the hypercalcemia determined by the calcium level as well as presenting symptoms and laboratory findings. Generally, neurologic and renal complications of hypercalcemia increase with increasing severity of hypercalcemia.. Mild hypercalcemia with calcium levels 10.5-11.9 mg/dL usually is asymptomatic and does not require any specific treatment other than addressing the underlying malignant process and following general measures including removal of excess calcium intake from enteral feeds and supplements. Medications associated with hypercalcemia such as lithium, thiazide diuretics, vitamin D and calcitriol if present should also be withheld.. Treatment of moderate hypercalcemia with calcium levels 12.0-13.9 mg/dL largely depends on patients symptoms and renal function. Generally, intravascular volume repletion is sufficient in these patients to increase calciuresis and decrease calcium levels by increasing ...
Parathyroid carcinoma is a rare disease leading to severe hypercalcemia due to hyperparathyroidism. Surgery is the primary treatment option. A more progressive form of the disease is characterized by parathyrotoxicosis, and subsequent hypercalcemia is the most common cause of death. We report a case presenting with severe hypercalcemia due to parathyrotoxicosis from parathyroid carcinoma treated for the first time using the monoclonal antibody denosumab as a rescue therapy and present long-term follow-up data. The 71-year-old patient presented with severe hypercalcemia due to metastatic parathyroid carcinoma. Despite undergoing treatment with bisphosphonates, cinacalcet hydrochloride, and forced diuresis, the patient`s condition deteriorated rapidly due to resistant hypercalcemia. Surgery performed because of spinal metastasis and forced diuresis lowered calcium levels, albeit they remained in the hypercalcemic range and significantly increased when forced diuresis was stopped. Considering a ...
In medicine, milk-alkali syndrome is characterized by high blood calcium caused by taking in too much calcium and absorbable alkali; common sources of calcium and alkali are dietary supplements taken to prevent osteoporosis and antacids. If untreated, milk-alkali syndrome may lead to kidney failure or death. It was most common in the early 20th century, but since the 1990s, there has been an increase in the number of cases reported, linked to the increased use of calcium supplements to address or prevent osteoporosis. The most common symptoms are poor appetite, dizziness, headache, confusion, psychosis, and dry mouth; laboratory tests may show that a person with milk-alkali syndrome has high blood calcium, kidney failure, and metabolic alkalosis. Milk-alkali syndrome is caused by taking too much calcium (usually in the form of dietary supplements taken to prevent osteoporosis) and absorbable alkali (as are found in antacid drugs). The mechanism by which ingesting too much calcium and alkali ...

Familial hypocalciuric hypercalcemia (HHC) is a heritable disorder of mineral homeostasis that is transmitted as an autosomal dominant trait with a high degree of penetrance. HHC is characterized biochemically by lifelong elevation of serum calcium concentrations and is associated with inappropriately low urinary calcium excretion and a normal or mildly elevated circulating parathyroid hormone (PTH; {168450}) level. Hypermagnesemia is typically present. Individuals with HHC are usually asymptomatic and the disorder is considered benign. However, chondrocalcinosis and pancreatitis occur in some adults (summary by {17:Hannan et al., 2010 ...
Here we describe, to our knowledge, the first case where an evolution of mechanisms responsible for hypercalcemia occurred in undifferentiated thymic carcinoma and discuss specific management strategies for hypercalcemia of malignancy (HCM).|i| Case Description|/i|. We report a 26-year-old male with newly diagnosed undifferentiated thymic carcinoma associated with HCM. Osteolytic metastasis-related hypercalcemia was presumed to be the etiology of hypercalcemia that responded to intravenous hydration and bisphosphonate therapy. Subsequently, refractory hypercalcemia persisted despite the administration of bisphosphonates and denosumab indicative of refractory hypercalcemia. Elevated 1,25-dihydroxyvitamin D was noted from the second admission with hypercalcemia responding to glucocorticoid administration. A subsequent PTHrP was also elevated, further supporting multiple mechanistic evolution of HCM. The different mechanisms of HCM are summarized with the role of tailoring therapies based on the particular
BACKGROUND:. The clinical and pathological characteristics of hyperparathyroidism-induced hypercalcemic crisis (HIHC) are incompletely described. The present study was designed to elucidate the nature and effects of HIHC in patients undergoing parathyroidectomy in our unit.. METHODS:. A prospective database of 1,754 consecutive patients with primary hyperparathyroidism (PHPT) who underwent parathyroidectomy from 1991-2009 identified 67 (41 women) patients presenting with HIHC. Hyperparathyroidism-induced hypercalcemic crisis was defined as symptoms and signs of acute calcium intoxication with a concomitant total albumin corrected calcium level,13.5 mg/dl (range: 8.8-10.2 mg/dl). Clinical and pathological characteristics were evaluated. Data are expressed as mean±SEM.. RESULTS:. Mean age at presentation was 56.7±2.2 years. Twenty-four of 67 patients (35%) required preoperative in-hospital management. Of these, all were treated with saline resuscitation, whereas 20/24 (83%) were treated ...
If the serum phosphorus concentration is increased and kidney function is normal, hypervitaminosis D or bone osteolysis from metastatic or primary bone neoplasia are the primary differentials.. Determining whether kidney failure is primary or secondary to hypercalcemia caused by another disorder, when hyperphosphatemia and hypercalcemia coexist with azotemia, can be difficult. Measurement of serum ionized calcium concentration may help identify dogs and cats with renal failure-induced hypercalcemia. Serum ionized calcium concentrations are typically normal or decreased in renal failure and increased in hypercalcemia caused by other disorders.. Hypercalcemia of malignancy and primary hyperparathyroidism are the primary differentials when hypercalcemia and normal to low serum phosphorus concentrations are identified. The most common malignancy is lymphoma. A careful review of the history and physical examination findings may provide clues to the diagnosis. Systemic signs of illness suggest ...
Symptoms: mild to moderate hypercalcemia (11 to 14 mg/100 mL) often has no symptoms, but when levels , 15 mg/100 mL, clinical changes become more common. Hypercalcemia produces changes primarily in the central nervous system (e.g., mental status changes), the gastrointestinal tract (e.g., vomiting), the kidneys (e.g., polyuria, renal calculi, oliguric renal failure), and the heart (e.g., shortened P-R or Q-T interval, possible QRS widening).. Today, hypercalcemia is most commonly diagnosed in asymptomatic patients, whereas clinical features previously were the earliest manifestations.. Etiologies: thiazide diuretic therapy, malignancy (now known as humoral hypercalcemia of malignancy), granulomatous disease (related to increased intestinal absorption of calcium induced by elevated calcitriol levels), vitamin D intoxication, or parathyroid hormone adenoma. Additional causes of hypercalcemia include lithium therapy, thyrotoxicosis, pheochromocytoma, immobilization, vitamin A intoxication, renal ...
The case: A 33-year-old woman 37/52 pregnant presented with epigastric pain, vomiting, proteinuria and hypertension and a deteriorating GCS (11/15). A CT head was normal. Blood showed hyperuricaemia and acute kidney injury. She was transferred to the operating room for caesarean section with suspected fulminating pre-eclampsia following a fall in GCS to 8. Immediately prior to general anaesthetic induction she had a generalized seizure. She was induced, intubated and commenced on IV magnesium and labetolol. Following successful delivery, a large pedunculated fibroid was noted on the left side of the uterus. She was transferred to intensive care sedated, intubated and ventilated. Routine blood testing demonstrated severe hypercalcaemia, corrected serum calcium of 5.05 mmol/l. PTH was at the lower limit at 1.3 pmol/l (normal range 1.3 - 7.6 pmol/l). Treatment consisted of IV rehydration with 0.9% sodium chloride 4 litres in 24hr, IV Pamidronate (a bisphosphonate) 60mg over 2 hours. Over the next 3 ...

Sometimes, you might have hypercalcemia (too much calcium in the blood) and not have any warning signs. You may need to have blood tests on a regular schedule while you are being treated with this medicine to check the amount of calcium and phosphorus in your blood. Keep all appointments your doctor makes for you. If you have mild hypercalcemia, you may lose your appetite and have nausea, vomiting, or constipation. If the problem is severe, you may feel confused or extremely excited. Stop using this medicine and call your doctor right away if you think you might have severe hypercalcemia. Do not take other calcium-containing products including dietary supplements and antacids. Your doctor may adjust the amount of calcium-containing foods you eat. Taking too much calcium while you are taking this medicine can cause hypercalcemia. ...

If patients with chronic hyperuricemia are left untreated, gouty tophi can develop and usually deposit in subcutaneous tissues. Tophi have also been shown to occur within joints, as was the case in our patient, but have also been shown to deposit in various tissues such as kidney, breast and spinal cord [1]. The histological hallmark of a gouty tophi is created when MSU crystals aggregate with intercrystalline matrix and induce surrounding granuloma formation [2]. The MSU crystals serve as the inciting antigen which leads to an intense inflammatory reaction of macrophages, lymphocytes and large foreign body giant cells which may have completely or partially engulfed the mass of crystals [3].. Hypercalcemia has been described in patients with many types of granulomatous disorders such as tuberculosis, Wegeners granulomatosis, and Crohns disease. By far the most widely evaluated and one of the more common causes of hypercalcemia due to granulomatous inflammation is sarcoidosis [4, 5]. The ...
1. The relationship between osmolal clearance (Cosm) and the reabsorption of solute free water (Tch2o) was examined during mannitol and hypertonic saline diureses in both normocalcaemic and hypercalcaemic rabbits.. 2. At high values for Cosm (2-4 ml/min) in normocalcaemic rabbits Tch2o during saline diuresis exceeded that during mannitol diuresis as previously shown.. 3. Prolonged hypercalcaemia (72-96 h) reduced Tch2o in both mannitol and saline diureses.. 4. Brief hypercalcaemia (18-24 h) abolished the increment in Tch2o normally seen during saline, as compared with mannitol diuresis. This impairment of Tch2o during saline diuresis occurred at a time after the start of hypercalcaemia when Tch2o during mannitol diuresis was still unaffected.. 5. The results cannot be attributed to an effect of hypercalcaemia on membrane permeability to water, and are best explained by a reversible limitation of sodium transport in Henles loop. This interpretation is supported by the fact that the ...
Abstract. Ten hypercalcaemic patients with solid tumours were studied to evaluate the renal response on PTH infusion as assessed by nephrogenous cAMP excretion and maximum tubular re-absorption of phosphate. In addition, 20 normocalcaemic patients, 11 with an adenocarcinoma and 9 with a squamous cell carcinoma, were studied. All cancer patients had moderately extensive disease. Results were compared with those of 9 patients with primary hyperparathyroidism and with 10 elderly controls. All groups studied had comparable renal function, magnesium and 25-hydroxy-vitamin D levels. Comparable results were obtained in patients with an adenocarcinoma and in controls. cAMP response (Δ nephrogenous cAMP) was significantly lower in the hypercalcaemic patients with a solid tumour compared with the controls (8.13 ± 4.68 nmol/100 ml glomerular filtrate vs 29.52 ± 25.62 nmol/100 ml glomerular filtrate; P , 0.005). In the group of patients with primary hyperparathyroidism Δ nephrogenous cAMP was 13.41 ± ...

Hypercalcemia may be resulted from either increased calcium intake or increased gastrointestinal absorption.. Individuals, who ingest large Calcium amounts and also use Calcium consisting antacids, may progress Hypercalcemia. Vitamin D overdose similarly may affect Calcium concentration in the blood by significant increase in calcium absorption from the gastrointestinal tract. However, the main cause of Hypercalcemia is disorder called Hyperparathyroidism, the excessive parathyroid hormones secretion by 1 or more of the 4 parathyroid glands.. About 90% of patients with primary Hyperparathyroidism have adenoma (noncancerous tumor) in one of these small glands. In the rest 10%, the glands enlarge and produce excessive hormone amounts. Rarely, parathyroid glands cancer result in Hyperparathyroidism.. Hyperparathyroidism is more likely to occur in females than in males. It is also more likely to progress in older individuals and in those people who received radiation therapy to the neck in the ...
Familial multiple endocrine neoplasia type 1 (MEN1), familial hypocalciuric (or familial benign) hypercalcemia (FHH), hyperparathyroidism jaw tumor syndrome (HPT-JT), other causes of familial isolated hyperparathyroidism (FIH), and pseudohypoparathyroidism (PHP) are disorders of metabolism that are generally inherited in an autosomal dominant fashion. MEN1 is characterized by overgrowth and hyperfunction of the parathyroids, anterior pituitary and gastrointestinal endocrine tissue. MEN1, p15, p18, p21, and p27 are identified genes for MEN 1- like states. FHH is characterized by a usually benign syndrome sometimes mistaken for typical primary hyperparathyroidism, which may result in unnecessary and unsuccessful parathyroid surgery. The CASR gene for the calcium-sensing receptor of the parathyroid cell is mutated in of most FHH kindreds;a minority of kindreds with FHH have mutation of the GA11 or AP2S gene. HPT-JT is a distinctive subtype of familial isolated hyperparathyroidism that has ...

BACKGROUND: The kidney is one of the affected organs involved in the clinical symptoms of parathyroid hormone (PTH)-related disorders, like primary hyperparathyroidism and familial hypocalciuric hypercalcemia. The molecular mechanism(s) underlying alterations in renal Ca(2+) handling in these disorders is poorly understood. METHODS: Parathyroidectomized and PTH-supplemented rats and mice infused with the calcimimetic compound NPS R-467 were used to study the in vivo effect of PTH on the expression of renal transcellular Ca(2+) transport proteins, including the epithelial Ca(2+) channel transient receptor potential, vanilloid, member 5 (TRPV5), calbindins, and the Na(+)/Ca(2+)-exchanger (NCX1). In addition, the effect of PTH on transepithelial Ca(2+) transport in rabbit connecting tubule/cortical collecting duct (CNT/CCD) primary cultures was determined. RESULTS: Decreased PTH levels in parathyroidectomized rats or NPS R-467-infused mice, resulted in reduced expression of these proteins, which is ...

If a pet has both hypercalcemia and high levels of parathyroid hormone, then a disease called hyperparathyroidism is present. There are two main types of hyperparathyroidism: one form is caused by a tumor in the parathyroid glands, and is called primary hyperparathyroidism. The other form is associated with either longstanding kidney disease or poor nutrition, and is called secondary hyperparathyroidism.. If a pet has hypercalcemia but has low levels of parathyroid hormone, then it suggests there has been a breakdown in the normal mechanism that controls calcium levels. This is worrisome because it may mean that there is underlying cancer. The pet should be thoroughly examined, and additional diagnostic tests may be recommended, including radiography, ultrasound, cytology or biopsy. ...

Since calcitriol is believed to be the active hormone which exerts vitamin D activity in the body, adverse effects are, in general, similar to those encountered with excessive vitamin D intake, ie, hypercalcemia syndrome or calcium intoxication (depending on the severity and duration of hypercalcemia) (see WARNINGS). Because of the short biological half-life of calcitriol, pharmacokinetic investigations have shown normalization of elevated serum calcium within a few days of treatment withdrawal, ie, much faster than in treatment with vitamin D3 preparations. The early and late signs and symptoms of vitamin D intoxication associated with hypercalcemia include:. Early: weakness, headache, somnolence, nausea, vomiting, dry mouth, constipation, muscle pain, bone pain, metallic taste, and anorexia, abdominal pain or stomach ache.. Late: polyuria, polydipsia, anorexia, weight loss, nocturia, conjunctivitis (calcific), pancreatitis, photophobia, rhinorrhea, pruritus, hyperthermia, decreased libido, ...

Hypercalcemia is frequently associated with a urinary concentrating defect and overt polyuria. The molecular mechanisms underlying this defect are poorly understood. Dysregulation of aquaporin-2 (AQP2), the predominant vasopressin-regulated water channel, is known to be associated with a range of congenital and acquired water balance disorders including nephrogenic diabetes insipidus and states of water retention. This study examines the effect of hypercalcemia on the expression of AQP2 in rat kidney. Rats were treated orally for 7 d with dihydrotachysterol, which produced significant hypercalcemia with a 15 +/- 2% increase in plasma calcium concentration. Immunoblotting and densitometry of membrane fractions revealed a significant decrease in AQP2 expression in kidney inner medulla of hypercalcemic rats to 45.7 +/- 6.8% (n = 11) of control levels (100 +/- 12%, n = 9). A similar reduction in AQP2 expression was seen in cortex (36.9 +/- 4.2% of control levels, n = 6). Urine production increased ...
Genetic testing for the CASR gene, which is associated with benign familial hypocalciuric hypercalcemia (BFHH), neonatal severe hyperparathyroidism (NSHPT), familial isolated hyperparathyroidism (FIHP), and autosomal dominant hypocalcemia (ADH).
More than 20 mutations in the CYP24A1 gene have been found to cause a type of idiopathic infantile hypercalcemia called infantile hypercalcemia 1, which is characterized by high levels of calcium in the blood (hypercalcemia) and urine (hypercalciuria) and deposits of calcium in the kidneys (nephrocalcinosis). The hypercalcemia typically causes vomiting, poor feeding, and an inability to grow and gain weight at the expected rate (failure to thrive) in infancy, although some affected individuals do not develop signs and symptoms of the condition until adulthood. Features in affected adults, whether they had symptoms in infancy or not, typically include hypercalciuria, nephrocalcinosis, and kidney stones (nephrolithiasis), although they may not cause any obvious health problems.. The CYP24A1 gene mutations that cause infantile hypercalcemia 1 reduce or eliminate the activity of the 24-hydroxylase enzyme. A shortage of this enzymes function impairs the breakdown of calcitriol. The resulting excess ...
The protein encoded by this gene is a plasma membrane G protein-coupled receptor that senses small changes in circulating calcium concentration. The encoded protein couples this information to intracellular signaling pathways that modify parathyroid hormone secretion or renal cation handling, and thus this protein plays an essential role in maintaining mineral ion homeostasis. Mutations in this gene are a cause of familial hypocalciuric hypercalcemia, neonatal severe hyperparathyroidism, and autosomal dominant hypocalcemia. [provided by RefSeq, Aug 2017 ...
General consensus and contemporary guidelines, recommend surgery for primary hyperparathyroidism (pHPT)for all patients below the age of 50, for patients with pronounced hypercalcemia and for patients with organ complications to the disease (osteoporosis and decreased renal function).. The purpose of this study is to determine if surgery for pHPT, is appropriate for patients with moderate to mild hypercalcemia older than 65 years of age.. The hypothesis of the study is that surgery for pHPT in patients older than 65 years of age, and with mild hypercalcemia, will increase bone density and hence decrease future risk for fragility fractures compared to patients with follow-up only. ...
Two siblings, a 6-month-old sexually intact male weighing 2.5 kg (cat 1) and a sexually intact female (cat 2) British Shorthair cat weighing 2.3 kg, were examined because of a 3-week history of polyuria, lethargy and laboured breathing. One year previously, another sibling (cat 3) had been presented because of similar, yet more severe, clinical signs at the age of 5 months. Physical examination revealed lethargy, dehydration and polypnoea with slightly increased inspiratory effort. Diagnostic investigation revealed severe hypercalcaemia (cats 1-3), renal azotaemia (cats 1 and 3) and a radiologically generalised miliary interstitial pattern of the lungs (cats 1-3) attributable to hypervitaminosis D caused by ingestion of commercial cat food. Cat 3 was euthanased. Cats 1 and 2 were treated with isotonic saline solution (180 ml/kg IV daily), sucralfate (30 mg/kg PO q12h), terbutaline (only cat 1: 0.1 mg/kg SC q4h), furosemide (1.5 mg/kg IV q8h) and tapering doses of prednisolone. Cat 2 was normal ...

Calciphylaxis is characterized by diffuse precipitation of tissue calcium, and is a rare fatal entity of calcific vasculopathy associated with tissue necrosis.1 Its description was first reported in skin, and the calciphylaxis of other organs has rarely been reported.3 Unlike metastatic calcification, calciphylaxis is accompanied by damage to ischemic and necrotic tissue.4,5 Metastatic calcification and calciphylaxis are metabolic disorders,3 for which the precise pathogenesis has not yet been determined. Multifactorial causes have been suggested: persistent or transient hyperphosphatemia, vitamin D intoxication, hypercalcemia, steroid therapy in renal transplant recipients, and deficiencies or functional abnormalities of proteins C and S, warfarin therapy, or secondary hyperparathyroidism.6-8 Hypoparathyroidism as well as hyperparathyroidism are rare causes of metastatic calcification.9 Other theories involving proinflammatory cytokines, including interleukin-6 and tumor necrosis factor α, ...
The patient received a potassium supplement, intramuscular administration of calcitonin, and intravenous (IV) fluid hydration, and she was admitted to the hospital for further workup. After treatment with IV fluids, calcitonin, and zoledronic acid, her calcium level decreased to 11.5 mEq/L. With improvement of her nausea and vomiting, the patient was discharged. It was recommended that she follow-up with an oncologist as an outpatient.. Approximately 1 week later, the patient returned to the Emergency Department with similar symptoms and was found to have an elevated calcium level of 15 mEq/L. She was given IV fluids and pamidronate, which improved her symptoms. She was discharged, with further workup to be done on an outpatient basis. This patient presented a total of 4 times to the Emergency Department with similar symptoms of hypercalcemia, as shown in Figure 1.. A bone marrow biopsy was performed, and the specimen demonstrated trilineage hematopoiesis without signs of myeloma. Specifically, ...

Clinical studies in patients with hypercalcemia of malignancy (HCM) showed that single-dose infusions of zoledronic acid are associated with decreases in serum calcium and phosphorus and increases in urinary calcium and phosphorus excretion.. Osteoclastic hyperactivity resulting in excessive bone resorption is the underlying pathophysiologic derangement in hypercalcemia of malignancy (HCM, tumor-induced hypercalcemia) and metastatic bone disease. Excessive release of calcium into the blood as bone is resorbed results in polyuria and gastrointestinal disturbances, with progressive dehydration and decreasing glomerular filtration rate. This, in turn, results in increased renal resorption of calcium, setting up a cycle of worsening systemic hypercalcemia. Reducing excessive bone resorption and maintaining adequate fluid administration are, therefore, essential to the management of hypercalcemia of malignancy.. Patients who have hypercalcemia of malignancy can generally be divided into two groups ...

Since many patients (50% or more) with cancer and hypercalcemia do not have demonstrable bone metastases or PHPT, it has long been suspected that the cancer could be producing a parathyroid hormonelike substance. The parathyroid hormone-related protein (PTHrP) molecule has a C-terminal end and an N-terminal end like PTH; in addition, a portion of the PTHrP amino acid sequence is identical to that of PTH, although the majority of the PTHrP molecule is not. Also, it has been found that certain normal tissues can produce PTHrP (including the keratinized layer of skin epidermis, lactating breast tissue, placenta, adrenal, and a few others). PTHrP has recently been isolated and cloned, and antibodies have been obtained that react against it. Several investigators have reported results using homemade test kits, and one commercial kit is now available. Results thus far with these first-generation kits show that about 50% (range, 20%-91%) of patients with solid malignancies and hypercalcemia have ...

The study by Raisz and colleagues reported in this issue (1), although based on a small number of samples, illustrates both the assets and limitations of commercially available radioimmunoassays for immunoreactive parathyroid hormone (iPTH). When the same samples from 15 patients with surgically proven hyperparathyroidism were analyzed, good agreement was found among three of the four participating laboratories. A positive correlation between serum calcium and iPTH was seen in two of the four laboratories and is reported to be present in a third when more samples are analyzed (2). The values obtained for plasma iPTH in 14 hypercalcemic patients with ...
Serum phosphorus (Phosphate) levels alone are of limited diagnostic value and should be correlated with serum calcium levels. An increased phosphorus with decreased calcium suggests either hypoparathyroidism or renal disease. A decreased phosphorus and an increased calcium suggests hyperparathyroidism or sarcoidosis. When both calcium and phosphorus are decreased diagnostic considerations include malabsorption, vitamin D deficiency and renal tubular acidosis. Increased phosphorus and normal or increased calcium suggests Milk-alkali syndrome or hypervitaminosis D. ...
Methylation Status of the CpG Islands in Vitamin D and Calcium-Sensing Receptor Gene Promoters Does Not Explain the Reduced Gene Expressions in Parathyroid Aden
82 Parathyroid hormone-related protein (PTHrP) is the causative factor of the paraneoplastic syndrome humoral hypercalcemia of malignancy (HHM), a complication of lung squamous-cell carcinomas (SCC). The epidermal growth factor receptor (EGFR) has been implicated in activating PTHrP gene expression in lung and breast cancer, as well as cultured keratinocytes. Inhibition of autocrine EGFR signaling has been shown to reduce plasma total calcium concentrations in a lung SCC xenograft model of hypercalcemia. The purpose of this study was to identify the mechanism by which the EGFR is stimulated and how PTHrP gene expression is increased. The tumor-necrosis factor α-converting enzyme (TACE) is the metalloprotease that cleaves EGFR ligands, including amphiregulin (AREG), making them accessible to the EGFR, was detected at high levels in a panel of lung SCCs. These cells were also evaluated by quantitative real-time PCR (QRT-PCR) for mRNA expression of the EGFR ligands; AREG, transforming growth ...
Background/aim: Sagliker syndrome (SS) develops as a continuation of chronic kidney disease and secondary hyperparathyroidism conditions. It was thought that there are some genetic predisposition factors leading to SS. The calcium-sensing receptor (CaSR) is essential for calcium homeostasis in the body. We aimed to examine SS patients for chromosome aberrations (CAs) and CaSR gene abnormalities in exons 2 and 3. ...
We believe this is the first case report of anunusual presentation of hypercalcemia due to sarcoidosis mimicking metastatic colon carcinoma. A 68 year old lady with a background history of pancolectomy and neoadjuvant chemotherapy for Duke C1 rectal carcinoma under surveillance, ulcerative colitis, type 2 diabetes mellitus presented to the clinic with hypercalcemia with low parathyroid hormone (PTH) and symptoms of tiredness. Her blood test showed Adj Ca of 2.8 mmol/l, PTH , 2.5 pmol/l, Vitamin D 18 mol/l, ALP 177 U/l. She was commenced on 800 IU of vitamin D, ordered for bone scan, 24 h urine calcium excretion ratio, myeloma screen. Her surveillance CT scan couple of months earlier was reported stable features. She had an acute medical admission with unsteadiness of gait, tiredness and nausea. The adjusted calcium level was reported as 3.6 mmol/l with suppressed PTH. She was resuscitated with intravenous fluids and bisphosphate infusion. A CT scan of abdomen, chest and pelvis was organised that ...

PTHrP may be used for the differential diagnosis of hypercalcaemia of unknown origin where other diagnostic tests have not identified the aetiology of the hypercalcaemia but where PTH and iCa suggest parathyroid independent hypercalcaemia. PTHrP is a hormone that can be produced by dogs, cats and horses with several different types of tumours and is considered to be the underlying cause of hypercalcaemia of malignancy in many but not all cases. Almost all anal gland apocrine neoplasia, the majority of hypercalcaemic lymphomas and smaller percentages of myeloma and carcinomas are PTHrP positive. Circulating levels of PTHrP in normal dogs are almost undetectable (< 0.5 pmol/L). Levels greater than 2.0 pmol/L are considered significant in dogs. Cats appear to show similar values. Please note: SAMPLE PREPARATION IS CRITICAL FOR THE ACCURATE ANALYSIS OF PTHrP (see procedure for PTH on p53). THE APROTININ EDTA TUBE SUPPLIED WITH THE TRANSPORT PACK SHOULD BE USED FOR THE COLLECTION OF PTHrP ...
To the Editor: We have read with great interest the report by Drs. Shackney and Hasson describing the occurrence in two patients of hypocalcemia, hypotension, oliguria, and death as a complication of the rapid intravenous infusion of phosphate salts in the treatment of hypercalcemia (Ann. Intern. Med. 66: 906, 1967). Almost simultaneously, Breuer and LeBauer (1) have reported in the May 1967 issue of the Journal of Clinical Endocrinology and Metabolism an additional patient in whom a similar outcome was observed.. In view of these adverse effects, it appeared propitious to describe briefly the results of our continuing experience with ...
In the present study, the case of a 41-year-old man with immunoglobulin (Ig)M multiple myeloma (MM) that presented with an unusually non-aggressive clinical course who has survived for ,9 years to date, is presented. Initial diagnosis of symptomatic MM was established according to the International Myeloma Working Group consensus statement and guidelines. Due to the mild symptoms, no therapy was administered and the patient was closely followed up. Eight years after initial diagnosis, clinical, morphological and genetic progression occurred with the development of hypercalcemia, progressively deteriorating polyneuropathy, clonal expansion of plasma cells up to 50% of hematopoietic cells and demonstration of the typical t(11;14) translocation (Ig heavy chain locus rearrangement ...
You have been diagnosed with hypercalcemia (too much calcium in your blood). Calcium is a mineral that helps develop bones and teeth, controls heart rhythm, and allows muscles to contract.

Zuschriften DOI: 10.1002/ange.200900071 Calcium Sensors Bioinspired Colorimetric Detection of Calcium(II) Ions in Serum Using Calsequestrin-Functionalized Gold Nanoparticles** Sunghyun Kim, Jeong Won Park, Dongkyu Kim, Daejin Kim, In-Hyun Lee, and Sangyong Jon* The calcium(II) ion is the most abundant cation in the body, and participates in various biological activities such as skeletal mineralization, blood coagulation, neurotransmission, excitation of skeletal and cardiac muscle, and stimulus-mediated hormone secretion.[1] Blood calcium levels range from 2.1 mm to 2.6 mm in healthy humans; this level is strictly maintained and varies by 3 % at most. Severe fluctuations in calcium levels are associated with many diseases. For instance, the common causes of hypercalcemia are primary hyperparathyroidism, malignant tumors, and hyperthyroidism.[2] Therefore, the accurate and fast estimation of blood calcium levels is of great importance. Several techniques are available to assess blood calcium ...
Current treatment of cancer-related hypercalcemia is limited by agents of limited effectiveness or excessive toxicity. Gallium nitrate is a new drug which both inhibits bone resorption and increases calcium content of bone. We have now treated 39 episodes of hypercalcemia with gallium nitrate administered as a continuous i.v. infusion for 5-7 days at 3 daily dose levels (100 and 200 mg/m2, and 50 mg/m2 by brief infusion followed by 150 mg/m2). Nadir calcium values were significantly lower (9.2 ± 1.5 mg/dl) for patients who received the highest dose relative to patients who received the lowest dose (10.5 ± 1.6 mg/dl, P , 0.001). While the actual percentage of patients who achieved normocalcemia was higher at the highest dose relative to the lowest dose (86 versus 60%), this difference was not statistically significant. Mean serum concentration of inorganic phosphorous declined significantly for all patients from 2.9 ± 0.86 mg/dl at base line to 1.8 ± 0.66 mg/dl (P , 0.001). Pharmacokinetic ...
Symptoms of short-term vitamin D toxicity are due to high calcium levels (also known as hypercalcemia) and include confusion, increased urination, increased thirst, loss of appetite, vomiting, and muscle weakness. Acute hypercalcemia may intensify tendencies for heart arrhythmias and seizures and may increase the effects of certain heart drugs. Long-term toxicity may cause kidney failure, increase in calcium deposits in the blood and soft tissue, bone demineralization and pain. Patients with conditions such as liver disease or chronic kidney failure may be at increased risk for developing vitamin D toxicity ...

Elevated blood calcium starts when the bones receive an inappropriate message to mobilize their calcium. This message is either from excess parathyroid hormone or from high amounts of parathyroid hormone-related protein. When calcium is removed from the bones, all that is left is a fibrous scaffold which is not really strong enough to support us.
There is a close correlation between treatment with calcitriol and the development of hypercalcemia.. All other vitamin D compounds and their derivative, including proprietary compounds or foodstuffs which may be fortified with vitamin D, should be withheld during treatment with calcitriol.. An abrupt increase in calcium intake as a result of changes in diet (e.g. increased consumption of dairy products) or uncontrolled intake of calcium preparations may trigger hypercalcaemia. Patients and their families should be advised that strict adherence to the prescribed diet is mandatory and they should be instructed on how to recognise the symptoms of hypercalcaemia.. As soon as the serum calcium levels rise to 1 mg/100 ml (250 pmol/l) above normal (9-11 mg/100 ml, or 2250-2750 pmol/l), or serum creatinine rises to , 120 pmol/l, treatment with calcitriol should be stopped immediately until normocalcemia ensues.(see section 4.2). Immobilized patients, e.g. those who have undergone surgery, are ...
Hypercalcemia is an abnormally high amount of calcium in the blood. Calcium is needed by the body to function properly. Calcium can affect your nerves, muscles, digestive tract, kidneys, and the way your heart functions. When the calcium level becomes too high, you may develop unusual symptoms. The calcium level in your blood is normally controlled by hormones, the kidneys, GI tract, and bone. Hypercalcemia may happen because your cancer has spread to the bones, causing calcium to be released. Or, your cancer may release certain hormones that affect the normal systems that control the calcium level in your blood. Hypercalcemia does not happen by drinking too much milk or by eating too many dairy products; the imbalance happens because of your cancer. The symptoms may come on gradually or may happen in a short period of time.. ...
A 63 year old man with IgG myeloma was found to have hypercalcaemia; specific hypocalcaemic measures such as intravenous fluids and pamidronate 60 mg followed by 1.6 g of oral sodium clodronate daily in addition to antimyeloma agents such as prednisolone, Adriamycin, and carmustine were unsuccessful in restoring eucalcaemia (fig 1). ...

I just had my parathyroidectomy 2 days ago at the Norman Parathryoid Center in Tampa, and thankfully so. I have been told for the past 4 years by my primary care doctor in Greensboro, NC, that my blood calcium levels of 10.2-10.4 have been normal, yet I knew that something was terribly wrong when I was diagnosed with osteoporosis, as well as GERD. I also had terrible heart palpitations my first year of having high "normal" blood calcium readings. All of these symptoms were thought to be more or less a condition of menopause. I was told to take calcium for my osteoporosis, which I refused to do, and instead I got online and found Dr. Norman. It is amazing to me that any doctor tells a patient that blood calcium levels of 10.0 or higher are normal...they are not, and can be dangerous if it continues on for years. I had 4 tumors on my parathyroids. Less than 1% of people with this disease have this situation. Had I gone to any other endocrinologist, they probably would have only removed the first ...
