In hospitalised patients hypercalcaemia is most often caused by malignancy. It occurs in 20-30% of patients with cancer. Most commonly this is due to parathyroid hormone-related peptide (PTHrP) secretion or direct action of boney metastases although other mechanisms exist. Symptoms can be non-specific. Mild hypercalcaemia is associated with polyuria and polydipsia. Moderate hypercalcaemia with constipation and muscle weakness. Severe hypercalcaemia can lead to arrhythmias, pancreatitis and coma. Investigations include, calcium, albumin, phosphate and ALP levels. Mainstays of treatment involves IV fluid rehydration and bisphosphonates. Haemodialysis or use of a human monoclonal antibody denosumab maybe indicated in refractory cases.
