Try to minimize calcium intake in foods and supplements. Hypercalcemia caused by humoral effects and bone damage indicate poor outcomes in newly diagnosed multiple myeloma patients. PTH binds to the PTH receptor and causes several downstream effects, which cause serum calcium levels to increase. It is responsible for 80% of cases of HCM.6, 38 The most common tumors associated with this syndrome are squamous cell carcinomas of the lung, head and neck, esophagus, skin, or cervix or carcinomas of the breast, kidney, prostate, or bladder.13. Hereditary factors. 2020 Dec 23;13:13111-13119. doi: 10.2147/OTT.S275613. This includes treating the underlying cancer to lower calcium levels in the blood. If the disease is localized to a single adenoma on imaging, then a focused resection is planned. These include frailty or diminished functional capacity, gastroesophageal reflux, neurocognitive dysfunction, and (less commonly) fibromyalgia or cardiovascular disease.9, 16, 17 In patients with normocalcemic hyperparathyroidism, it is important to rule out secondary hyperparathyroidism—most commonly from vitamin D deficiency. Ways to take charge and make the time you spend with your doctor more productive . Glucocorticoids are a treatment option for hypercalcemia in patients with excessive vitamin D or endogenous overproduction of calcitriol secondary to lymphoma. Other supportive measures include correcting hypophosphatemia, because this may worsen the hypercalcemia. Systemic chemotherapy can be considered for tumor regression and has been found to be useful for lung cancer.33. After sufficient intravenous hydration, she started on zoledronic acid, which lowered her serum calcium back to the normal range. Cholecalciferol is then hydroxylated at the 25 position by the liver to form 25‐hydroxycholecalciferol, also called calcifediol. IV fluids and diuretics. Osteolysis mediated by local tumor cell secretion of osteoclast‐activating cytokines accounts for 20% of the cases of HCM and is most commonly seen in patients with breast cancer and multiple myeloma (Figure 2B).6, 29, 47 Activating cytokines include macrophage inflammatory protein 1α, interleukin 1 (IL‐1), IL‐3, IL‐6, tumor necrosis factor α (TNF‐α), TNF‐β, lymphotoxin, and prostaglandins.48 The osteolysis is not caused by direct tumor invasion and degradation of bone—a common misconception. Pamidronate and etidronate can be given intravenously, while risedronate and alendronate may be effective as oral therapy. Hypercalcemia and cancer: Differential diagnosis and treatment. Systemic management of neutralizing antibodies to MIP-1α or small molecule CCR-1-unique and CCR-5-unique antagonists inhibited tumor-brought about osteolysis and constrained sickness progression in mouse models of myeloma bone disorder. They also can be used to improve the efficacy of calcitonin by upregulating calcitonin receptors on osteoclasts.87 Occasionally, patients with HCM are unable to tolerate high‐volume fluid therapy because of renal or cardiac failure; hemodialysis with a low calcium bath can be considered. Similarly therapy for a fungal infection is vastly different than that for kidney injury. Prostate cancer hypocalcemia is usually treatable with human monoclonal antibody denosumab or by the use of bisphosphonates. After correction to euvolemia with normal saline, there are multiple medications that can be used to reduce the serum calcium level, including bisphosphonates, corticosteroids, calcitonin, and denosumab (a RANKL inhibitor). evaluation; malignancy; management; paraneoplastic syndrome. If a patient has hypoalbuminemia, the total serum calcium will be artificially low, and a corrected calcium level should be calculated. Please check your email for instructions on resetting your password. Multiple myeloma is also commonly a cause of HCM.33, 38. His parathyroid hormone measurement is elevated at 127.5 pg/mL (reference range, 9‐80 pg/mL). Instead, cytokines released by the tumor and surrounding cells, such as macrophages and endothelial cells, act similarly to PTH and PTHrP to cause increased secretion of RANKL by osteoblasts, which stimulates osteoclast differentiation and increased resorption of bone. The third most common cause of hypercalcemia is simply due to excessive doses of calcium carbonate. Corrected calcium versus ionized calcium measurements for identifying hypercalcemia in patients with multiple myeloma. Therefore, pamidronate may be safe in patients with impaired kidney function, although adjustment of the dose may be required. Español. Replacing fluids is the first and most important step in treating hypercalcemia. 1, In the healthy adult, the net daily calcium balance is zero. 2008 Feb 21;6:24. doi: 10.1186/1477-7819-6-24. Modern‐generation intravenous bisphosphonates include pamidronate (60‐90 mg intravenously over 2‐6 hours) and zoledronic acid (4 mg intravenously over 15‐30 minutes). The most common cause of inappropriately elevated PTH in all patients is primary hyperparathyroidism (PHPT). Another 1000 mg is in circulation in the extracellular fluid. Hypercalcemia, defined as serum calcium superior to 2.60 mmol/l, is the most common metabolic disorder in patients with cancer [ 1 – 2 ]. An Atypical Presentation of Primary Hyperparathyroidism in an Adolescent: A Case Report of Hypercalcaemia and Neuropsychiatric Symptoms Due to a Mediastinal Parathyroid Adenoma. NIH Paraneoplastic Disorders Associated with Miscellaneous Neoplasms with Focus on Selected Soft Tissue and Undifferentiated/ Rhabdoid Malignancies. Intravenous (IV) fluids, to dilute calcium i… Cancer Imaging . In contrast, hypercalcemia in the patient with a history of cancer presents in a … 4. Serum Calcium Levels Before Antitumour Therapy Predict Clinical Outcomes in Patients with Nasopharyngeal Carcinoma. HCM usually presents with severe clinical symptoms. Bisphosphonates inhibit IL‐6 production by human osteoblast‐like cells, Neridronate and human osteoblasts in normal, osteoporotic and osteoarthritic subjects, Treatment of hypercalcemia of malignancy with intravenous etidronate: a controlled, multicenter study, Treatment of hypercalcemia of malignancy with bisphosphonates, Zoledronic acid is superior to pamidronate in the treatment of hypercalcemia of malignancy: a pooled analysis of two randomized, controlled clinical trials, Disodium pamidronate for treating severe hypercalcemia in a hemodialysis patient, Treatment of hypercalcaemia with pamidronate in patients with end stage renal failure, Incidence, risk factors, and outcomes of osteonecrosis of the jaw: integrated analysis from three blinded active‐controlled phase 3 trials in cancer patients with bone metastases, Bisphosphonates, hypercalcemia of malignancy, and osteonecrosis of the jaw, Denosumab and bisphosphonates: different mechanisms of action and effects, Accuracy of MDCT in predicting site of GI tract perforation, Denosumab for treatment of hypercalcemia of malignancy, The role of RANK‐ligand inhibition in cancer: the story of denosumab, The role of denosumab in the prevention of hypercalcaemia of malignancy in cancer patients with metastatic bone disease, Protracted hypocalcaemia following a single dose of denosumab in humoral hypercalcaemia of malignancy due to PTHrP‐secreting neuroendocrine tumor, The effects of calcitonin in hypercalcemia in patients with malignancy, Salmon calcitonin in the acute management of hypercalcemia, Regulation of calcitonin receptor by glucocorticoid in human osteoclast‐like cells prepared in vitro using receptor activator of nuclear factor‐B ligand and macrophage colony‐stimulating factor. Incidentally detected hypercalcemia usually presents in an indolent manner and is most likely caused by primary hyperparathyroidism. Most recently, bisphosphonate drugs h… He describes an episode of nephrolithiasis 9 years prior. Glucocorticoids are also given to treat hypercalcemia caused by excess extrarenal 1,25(OH) 2 D and multiple myeloma. 2020 Mar 25;13(1):321-329. doi: 10.1159/000506100. Replacing fluids lost through vomiting and urination. Clipboard, Search History, and several other advanced features are temporarily unavailable. In the kidney, hypercalcemia can lead to nephrolithiasis, which may be silent or symptomatic. Prior reports suggest patients with hyponatremia and hypercalcemia are asymptomatic in early stages but can become symptomatic if untreated. These four tiny glands are situated behind the thyroid gland. After a diagnosis of PHPT is made, parathyroidectomy should be considered for all symptomatic patients and most asymptomatic patients. It is important to consult your doctor if you suspect you may have hypercalcemia. This final step is regulated by PTH, and calcitriol is the active form of vitamin D. Calcitriol increases serum calcium by causing increased calcium absorption in the intestines, increased calcium reabsorption in the kidneys, and stimulation of osteoblasts to reabsorb calcium from bone.1, 2, The parafollicular C cells of the thyroid gland secrete calcitonin. Learn more. The initial workup, differential diagnoses, confirmatory laboratory testing, imaging, and medical and surgical management of hypercalcemia are described in the patient with cancer. Once the cause of hypercalcemia is known, your healthcare team can treat it. As the patient’s dehydration worsens, this worsens the renal and cardiac failure. The normal range is 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), with levels greater than 2.6 mmol/L defined as hypercalcemia. Hypercalcaemia, also spelled hypercalcemia, is a high calcium (Ca 2+) level in the blood serum. The cause of your hypercalcemia will … This is typically a subtotal parathyroidectomy in which 3.5 glands are removed. (B) Osteolytic Bone Lesion From Metastatic Breast Cancer. Although bisphosphonates are most commonly used to treat established hypercalcemia, they have also been given to prevent hypercalcemia and adverse skeletal events, particularly in patients with metastatic cancer to bone. Taking medication to stop bone from breaking down. All of these mechanisms serve to increase serum calcium levels.1, Vitamin D, which is partially regulated through PTH, also plays an important role in the regulation of calcium. Mild neurocognitive dysfunction occurs more frequently in hyperparathyroidism than in hypercalcemia from other causes and may be caused by the direct effect of PTH on the brain.3 Finally, when hypercalcemia is the result of a resorptive process, patients may also present with fragility fractures caused by osteopenia and osteoporosis.1. The patient was admitted to the hospital and treated with intravenous fluid resuscitation and calcitonin, and her mental status improved. Managing Your Care. This is because of polyuria secondary to calciuresis and also to decreased oral intake secondary to nausea and vomiting. Hypercalcaemia, also spelled hypercalcemia, is a high calcium (Ca 2+) level in the blood serum. Hypercalcemia of malignancy (HCM) typically is associated with severe clinical signs and symptoms and is often an oncologic emergency.6 Ninety percent of all cases of hypercalcemia in patients with and without cancer are caused by either HCM or PHPT. A review of cancer-related hypercalcemia suggests that up to 30% of all cancer patients develop the condition as a side effect of treatment. A history of smoking and exposure to other carcinogens, such as alcohol abuse and sunburns at an early age, also should be elicited as well as the use of medications that may alter calcium homeostasis (commonly, thiazide diuretics or lithium).9, In addition to a thorough physical examination evaluating for masses (head and neck, oropharynx, breast, abdomen, rectal), physical manifestations of hypovolemia, such as tachycardia, mucosal dryness, and skin tenting, should be noticed. Unlike other forms of HCM, calcitriol‐mediated HCM tends to be associated with a normal to high phosphorus level.29. A focus should be placed on the above‐mentioned signs, symptoms, and associated diagnoses of hypercalcemia. Cancer Basics. 5. It is safe to use these medications in patients with end‐stage renal disease.75, 76 Interestingly, although zoledronic acid has been associated with acute tubal necrosis and severe acute toxicity, pamidronate is only associated with focal segmental glomerular sclerosis leading to nephrotic syndrome, which develops over months of treatment. Many organs are involved in the regulation of calcium. Hypercalcemia of malignancy and new treatment options Hillel Sternlicht,1 Ilya G Glezerman1,2 1Division of Nephrology and Hypertension, Weill Cornell Medical College, 2Renal Service, Memorial Sloan Kettering Cancer Center, New York, NY, USA Abstract: Hypercalcemia of malignancy affects up to one in five cancer patients during the course of their disease. Irritability and seizures in neonates are non-specific signs. If the PTHrP is normal, then levels of 1,25‐dihydroxyvitamin D and 25‐hydroxyvitamin D can be assessed to help diagnose other forms of HCM. They are the most studied and are considered the most effective agents for treatment of the HCM.66 They work by inhibiting the osteoclasts from degrading bone through several mechanisms. The best treatment for hypercalcemia due to cancer is treatment of the cancer itself. Concurrent primary hyperparathyroidism and humoral hypercalcemia of malignancy in a patient with clear cell endometrial cancer. The initial evaluation of a patient with hypercalcemia should include a thorough history and physical. 2 In those conditions, agents such as oral prednisone (60 mg/d for 10 days) can be used or intravenous hydrocortisone (200 mg daily for 3 days), or equivalents. Lung cancer and breast cancer, as well as some blood cancers, can increase your risk of hypercalcemia. Calcitonin can be given intramuscularly or subcutaneously, but it becomes less effective after several days of use. In patients with incurable disease, if greater than 90% of the tumor can be removed, then palliative debulking surgery may control symptoms and improve quality of life.88 Other palliative or therapeutic options that may be used as adjuncts to debulk tumor burden include radiofrequency ablation, cryoablation, hepatic embolization, and external‐beam radiation. All of these lead to increased bone resorption.49, 50 Clinically, HHM and bone osteolysis differ from each other by PTHrP level, with elevated levels in HHM and low levels in bone osteolysis. Cancer-associated … Salmon calcitonin is given subcutaneously if hypercalcemia persists despite hydration and furosemide. The calcium nadir is reached in 4 to 7 days. The initial workup, differential diagnoses, confirmatory laboratory testing, imaging, and medical and surgical management of hypercalcemia are described in the patient with cancer. Hypercalcemia occurs when a person has too much calcium in their blood. Algorithm for the Evaluation and Treatment of a Patient With Hypercalcemia and a History of Cancer. Treatment for hypercalcemia is based on a number of factors, including the condition of the patient and the severity of the hypercalcemia. You might be … Finally, hyperthyroidism, adrenal insufficiency, pheochromocytoma, and chronic immobility also can cause hypercalcemia through increased osteoclast activity.13, Once the diagnosis is made, the first step in the management of a patient in hypercalcemic crisis is to stabilize the patient with intravenous fluid resuscitation. Hypercalcemia is a disorder commonly encountered by primary care physicians. Hypercalcemia and Cancer: Differential Diagnosis and Treatment Jonathan Zagzag, MD, MPH1, Mimi I. Hu, MD2, Sarah B. Fisher, MD1 and Nancy D. Perrier, MD, FACS3 Abstract: Incidentally detected hypercalcemia usually presents in an indolent manner and is most likely caused by primary hyperparathyroidism. diagnostic pitfalls and surgical intervention, Medical treatment of malignancy‐associated hypercalcemia. Parathyroid carcinoma (PC) may be suspected preoperatively in the setting of marked hypercalcemia (greater than 14 mg/dL), PTH more than 3 or 4 times normal levels, or based on intraoperative findings such as local invasion. You may also need other treatments for hypercalcemia, including the following: Replacing fluids. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username. A minimally invasive parathyroidectomy was performed starting with the right inferior gland, and the intraoperative PTH dropped after removal of this gland. Hypercalcemia (defined as a serum calcium level >10.5 mg/dL or 2.5 mmol/L) is an important clinical problem [1]. Patients may be able to treat their hypercalcemia simply by eating less calcium.  |  Similarly therapy for a fungal infection is vastly different than that for kidney injury. Hypercalcemia in prostate cancer patients is where the blood has high calcium content that is often above the standard recommended levels. Dialysis is generally reserved for those with severe hypercalcemia. The average adult consumes approximately 1000 mg of calcium in their diet, of which 500 mg is absorbed, and the intestines secrete 325 mg, leading to a net absorption of 175 mg daily, and the rest is excreted in the feces. In this approach, the suspected gland is resected without exploring the other 3 glands. Strategies for treating hypercalcemia include: 1. A sestamibi scan and ultrasound localized a right inferior parathyroid adenoma. However, this practice has fallen out of favor because it has not been shown to be beneficial and can lead to electrolyte abnormalities.64, 65 Diuretics can be used to treat patients who become fluid‐overloaded after aggressive resuscitation. Other treatments for HCM include calcitonin, corticosteroids, and dialysis. Other diseases. Other forms of malignancy may also disrupt calcium homeostasis, and, in this situation, PTH levels typically are low. Oral bisphosphonates do not lead to serum concentrations that are high enough to deactivate osteoclasts, and they are only approved for the treatment of osteoporosis. The first step of vitamin D metabolism occurs at the skin, where ultraviolet light catalyzes the production of Vitamin D3, also called cholecalciferol, from 7‐dehydrocholesterol. This should be a decision that includes the patient and a surgeon. Incidentally detected hypercalcemia usually presents in an indolent manner and is most likely caused by primary hyperparathyroidism. Of course, sometimes treatment of hypercalcemia must begin before a diagnosis is made or before antineoplastic treatment has its effect. Minelli R, Meoli A, Tiri A, Fanelli U, Iannarella R, Gismondi P, Esposito S. Front Endocrinol (Lausanne). Tertiary hyperparathyroidism occurs when the parathyroid glands become autonomously functional after correcting the inciting cause of secondary hyperparathyroidism, and mediating hypercalcemia. A review of cancer-related hypercalcemia suggests that up to 30% of all cancer patients develop the condition as a side effect of treatment. Bone mineral density demonstrates osteoporosis, with a T‐score of −2.6 in the forearm. Treatment of cancer-related hypercalcemia Semin Oncol. Common causes of HCM include HHM and local bone osteolysis. Pancreatitis may also occur, although the mechanism for this is unknown. PHPT is the major cause of hypercalcemia in the ambulatory population, comprising up to 60% of cases, while malignancy represents the leading cause in hospit… Ann Pharmacother 1996;30:507-13. Adequacy of resection of all hyperfunctional tissue is confirmed by using an intraoperative PTH measurement. USA.gov. If you have cancer, your doctor will discuss treatment options with you to help you determine the best ways to treat hypercalcemia. Anti-Tumor Therapy Treatment of the underlying malignancy with systemic therapy (e.g. Cancer induced hypercalcemia is treated using denosumab. A review of records demonstrates the presence of hypercalcemia since at least 3 years prior, with calcium levels ranging from 10.2 to 10.8 mg/dL. eCollection 2020. The next step in management is to determine whether the disease is because of a single adenoma or multiple‐gland disease. A review of cancer-related hypercalcemia suggests that up to 30% of all cancer patients develop the condition as a side effect of treatment. The patient should be asked about the presence of cough, weight loss, or new masses and should be up to date with current guidelines regarding screening for colorectal, breast, and other cancers appropriate for the patient’s age, sex, and risk factors. Blood tests also can reveal whether your parathyroid hormone level is high, indicating that you have hyperparathyroidism.To determine if your hypercalcemia is caused by an underlying problem, such as cancer or sarcoidosis, your doctor might recommend imaging tests of your bones or lungs. Another option is to measure the ionized calcium level directly, which will be a better indicator of bioavailable calcium in the serum. Response to therapy can last for 1 to 3 weeks.73, Zoledronic acid is easier to administer and has been shown to have a more efficacious response than pamidronate, with a higher proportion of patients achieving normalization within 7 to 10 days of treatment and a longer duration of effect.74 Bisphosphonates have been associated with nephrotoxicity, and care must be used, because patients with HCM usually have some degree of renal impairment.66 It is sometimes necessary to delay administration of these medications until after the patient has been rehydrated or to reduce the dose based on the estimated glomerular filtration rate. The best treatment for hypercalcemia due to cancer is treatment of the cancer itself. 2020 Jan. .. Zagzag J, Hu MI, Fisher SB, Perrier ND. Hypercalcemia of malignancy and new treatment options Hillel Sternlicht,1 Ilya G Glezerman1,2 1Division of Nephrology and Hypertension, Weill Cornell Medical College, 2Renal Service, Memorial Sloan Kettering Cancer Center, New York, NY, USA Abstract: Hypercalcemia of malignancy affects up to one in five cancer patients during the course of their disease. Gallium nitrate, used to treat cancer-related hypercalcemia; Sensipar (cinacalcet), which lowers calcium in the blood; Steroids: These drugs may be used in some situations, although steroids can also lower calcium in some instances. Her PTHrP level was 15 pmol/L (reference range, less than 2.0 pmol/L). Glucocorticoids are effective in treating hypercalcemia due to some lymphomas, sarcoid, or other granulomatous diseases. She was sent to the emergency room and found to have a calcium level of 15 mg/dL. It presents indolently and is treated with surgery when necessary. Number of times cited according to CrossRef: Oral Cinacalcet Responsiveness in Non-Parathyroid Hormone Mediated Hypercalcemia of Malignancy. There should be strong consideration for the involvement of a palliative care specialist, because HCM is a poor prognostic indicator, and correction of the HCM does not improve survival.39, 47. This form of hypercalcemia is usually secondary to hypercalcemia of malignancy and can be fatal. It is discussed further below. From 5% to 15% of patients with Hodgkin lymphoma will develop hypercalcemia, and this is almost always secondary to tumor‐mediated overproduction of calcitriol.55, 56 The tumor cells or surrounding lymphocytes overexpress 1α‐hydroxylase, which causes ectopic conversion of 25 hydroxyvitamin D to 1,25‐dihydroxyvitamin D.57, 58 The hypercalcemia of excess calcitriol production is because of both increased intestinal and bone reabsorption of calcium. 2020 Oct;9(10):1019-1027. doi: 10.1530/EC-20-0380. Available drugs for initial therapy include calcitonin, plicamycin, and etidronate; several additional investigational agents have shown promising efficacy in controlling hypercalcemia of malignancy. Calcitonin decreases calcium levels by inhibiting osteoclast activity and renal reabsorption of calcium. Curr Opin Rheumatol. PC is rare (less than 1% of all cases of PHPT) and often is not diagnosed until after surgery.25 Once the diagnosis of PC is established, these patients should be referred to a tertiary facility with multidisciplinary teams specialized in the treatment of PC.24, 26, 27 Surgical treatment goals are to resect all tumor with negative margins without fracture of the specimen and without causing spillage of tumor cells onto the surgical field; resection of adjacent, uninvolved compartments is not necessary. Studies have shown it to be superior to pamidronate in terms of a more rapid onset and a longer duration of action. (See 'Glucocorticoids' above.) Substernal oxyphil parathyroid adenoma producing PTHrP with hypercalcemia and normal PTH level. These factors increase PTH production and parathyroid cell proliferation. The authors report no conflicts of interest. There are reserved indications for patients who have failed this treatment or in other select circumstances to perform a total parathyroidectomy with autotransplantation—but this is not the preferred initial operation. Even if you do have another underlying condition … The most predominant presentation of PHPT in the United States, Canada, and Europe is that of the seemingly asymptomatic patient who has incidentally identified hypercalcemia noted on routine laboratory testing.4, 5 Clinical manifestations of PHPT that initially may be attributed to other causes include nephrolithiasis, osteopenia/osteoporosis with or without pathologic fractures, neurocognitive decline, gastrointestinal symptoms, musculoskeletal pain, and potentially increased cardiovascular mortality.9, 14, 15 In areas with poor access to health care, patients may present with brown tumors of bone, which are the product of long‐standing osteoclast overactivity (Fig. Gastrointestinal manifestations include nausea, vomiting, and constipation and may be attributable to calcium's influence on smooth muscle. Hypercalcemia in the patient with cancer can be due to benign causes or to HCM. Case Rep Oncol. Parathyroid cancer is also a possibility in patients who present with an extremely elevated PTH level—although it is rare. Calcium exists in the serum as both free ionized calcium and bound calcium. This form of hypercalcemia is usually secondary to hypercalcemia of malignancy and can be fatal. As discussed above, these patients can become markedly hypovolemic. In contrast, hypercalcemia in the patient with a history of cancer presents in a … Hypercalcemia is a condition in which the calcium level in your blood is above normal. Learn about cancer, its causes, and its treatment. Care must be taken to avoid volume overload, especially in patients with acute or chronic renal and cardiac insufficiency. Historically, experts recommended against routine testing of PTHrP in the workup of HCM, because laboratory assays were unreliable, slow, and costly, and HHM was the most likely diagnosis regardless.6 The accuracy and reliability of laboratory assays for PTHrP have since improved because of newer double‐antibody techniques, and now a PTHrP level should be checked in all patients with suspected HCM. Am J Case Rep. 2017 Jan 6;18:22-25. doi: 10.12659/ajcr.900088. This is termed bilateral cervical exploration and was historically the standard operative approach for patients with PHPT. Familial hypocalciuric hypercalcemia is characterized by low urinary calcium excretion (defined as a calcium‐to‐creatinine clearance ratio less than 0.01 and 24‐hour urinary calcium excretion less than 100 mg) in the setting of hypercalcemia.5, 9 In FHH, an autosomal‐dominant inherited mutation in the calcium‐sensing receptor (CaSR) gene results in the inability of the parathyroid glands and kidneys to recognize alterations in serum calcium levels.
