INTRODUCTION. Hypercalcemia is a relatively common clinical problem. Among all causes of hypercalcemia, primary hyperparathyroidism and malignancy are the most common, accounting for greater than 90 percent of cases [].Therefore, the diagnostic approach to hypercalcemia typically involves distinguishing between the two Malignancy is usually evident clinically by the time it causes hypercalcemia, and patients with hypercalcemia of malignancy often have a poor prognosis. The mechanisms of hypercalcemia will be reviewed here. The clinical manifestations, diagnosis, and treatment of hypercalcemia are reviewed in detail separately

Thus, the management of hypocalcemia depends upon the severity of symptoms. In patients with acute symptomatic hypocalcemia, intravenous (IV) calcium gluconate is the preferred therapy, whereas chronic hypocalcemia is treated with oral calcium and vitamin D supplements. The treatment of hypocalcemia will be reviewed here If your hypercalcemia is mild, you and your doctor might choose to watch and wait, monitoring your bones and kidneys over time to be sure they remain healthy. For more severe hypercalcemia, your doctor might recommend medications or treatment of the underlying disease, including surgery Hypercalcemia • Pseudohypercalcemia - Elevated total calcium with a normal ionized calcium - Can occur in the setting of increased protein binding • Hyperalbuminemia • Calcium binding paraprotein • Correct for albumin concentration - Hyperalbuminemia • Subtract 0.8 from the total calcium for every 1 gm/dL increas hypercalcemia. Normal serum calcium levels are 8 to 10 mg per dL (2.0 to 2.5 mmol per L, Figure 1),although the exact range can vary optimal treatment and accurate prognosis Aggressive intravenous rehydration is the mainstay of management in severe hypercalcemia, and antiresorptive agents, such as calcitonin and bisphosphonates, frequently can alleviate the clinical..

Mild and asymptomatic moderate hypercalcemia is treated with oral rehydration and low calcium intake, while symptomatic or severe hypercalcemia is a potentially life-threatening medical emergency requiring hospitalization and immediate treatment with IV fluid repletion and medications that inhibit bone resorption (e.g., calcitonin. This drug is approved for the treatment of hypercalcemia in patients with parathyroid carcinoma or hypercalcemia caused by tertiary HPT. It can also be used to lower elevated calcium-phosphorus products in patients with end-stage renal disease who are on hemodialysis with secondary HPT. 14 It can only be used in PTH-mediated hypercalcemia May not require immediate therapy; however, an acute rise may cause symptoms necessitating treatment as described for severe hypercalcemia (see below) Symptomatic or Severe hypercalcemia (Ca >14 mg/dL) Patients are likely dehydrated and require saline hydration as initial therap Prognosis, like treatment, depends on the cause and severity of hypercalcemia. If the serum calcium is only slightly elevated, you will probably have few or no health complications. When hypercalcemia is the result of an underlying medical condition or disease, the prognosis depends on your overall health and your specific circumstances In response to hypercalcemia, calcitonin is secreted by the parafollicular C cells. Calcitonin lowers serum calcium by decreasing renal calcium and phosphorus reabsorption and also by decreasing bone reabsorption.8Calcitonin is not significant in overall calcium homeostasis, but it is an important therapeutic option

Approval was based on results from an open-label, single-arm study that enrolled patients with advanced cancer and persistent hypercalcemia after recent bisphosphonate treatment. The primary endpoint was the proportion of patients with a response, defined as albumin-corrected serum calcium (CSC) < 11.5 mg/dL (2.9 mmol/L Treatment for Hypercalcemia. Your doctor will recommend a treatment option based on the severity and cause of the condition. According to the Cleveland Clinic, your doctor may suggest the following to moderate your calcium levels. Drink more water: This will help flush out the excess calcium. Avoid calcium supplements. Avoid calcium-rich. Acute hypercalcemia is a life-threatening rather rare condition. This condition may represent an acute decompensation of a pre-existing hypercalcemia, or may be acute at the first instance of the electrolyte disturbance. Hypercalcemic patients can present with a broad spectrum of symptoms, but most Hypercalcemia 1. Hypercalcemia • Commonly encountered in Practice • Diagnosis often is made incidentally • The most common causes are primary hyperparathyroidism and malignancy • Diagnostic work-up includes measurement of serum calcium, intact parathyroid hormone (I-PTH), h/o any medications • Hypercalcemic crisis is a life-threatening emergenc The results of treatment for hypercalcemia depend on the underlying cause of the condition. If hypercalcemia is seen in the presence of cancer, the average 30-day survival rate is about 50%. The prognosis is excellent for many of the other causes of hypercalcemia provided the underlying cause is addressed and treated

Treatment approach for moderate hypercalcemia  Asymptomatic or mildly symptomatic individuals with chronic moderate hypercalcemia (calcium between 12 and 14 mg/dL) may not require immediate therapy.  It is important to note that an acute rise to these concentrations may cause marked changes in sensorium, which requires more aggressive therapy.  In these patients, treatment with saline hydration and bisphosphonates, as described for severe hypercalcemia on next page Treatment may include intravenous fluids, furosemide, calcitonin or pamidronate in addition to treating the underlying cause. The evidence for furosemide use, however, is poor. In those with very high levels, hospitalization may be required. Haemodialysis may be used in those who do not respond to other treatments

If the cause is known, medications and treatment are aimed toward the underlying cause. Oral and intravenous medications can be used in the treatment of hypercalcemia; however, some may require a hospital or monitored setting As there was no obvious malignancy, parathyroid hormone or Vitamin D abnormalities, and the patient was asymptomatic, it was felt that this was most consistent with a transient abnormality or familial hypercalciuric hypercalcemia. A pediatric endocrinologist recommended to recheck both 1,25-OH Vitamin D, and an ionized calcium in 1-2 weeks the causes of hypercalcemia in the patient with cancer and describes the diagnostic steps and treatment options for the most common causes of hypercalcemia. Many organs are involved in the regulation of calcium. Chief among these are the parathyroid glands and, when calcium levels drop, the parathyroid glands in account for the transient hypercalcemia that can occur after successful renal transplantation. Theophylline toxicity has been associated with mild hypercalcemia .
