RT Journal Article SR Electronic T1 Hypercalcaemia – presentation and management  JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 270 OP 273 DO 10.7861/clinmedicine.17-3-270 VO 17 IS 3 A1 Jeremy J O Turner YR 2017 UL http://www.rcpjournals.org/content/17/3/270.abstract AB Hypercalcaemia is a common disorder normally caused by primary hyperparathyroidism (PHPT) or malignancy. A proportion of cases present as an emergency, which carries a significant mortality. Emergency management of hypercalcaemia is based on intravenous rehydration with normal saline but when this is inadequate, bisphosphonate therapy is used; more recently the novel anti-resorbtive agent denosumab has been shown to have a useful role in treatment. It is estimated that up to 10% of all cases of PHPT presenting under the age of 45 years have an underlying genetic predisposition; nine potentially causative genes are now recognised and may be screened in routine clinical practice. Although parathyroidectomy is the only curative treatment for PHPT, this is indicated in a minority of cases. Many cases can be adequately managed conservatively and guidance from the 4th international workshop on the management of asymptomatic PHPT has recently been updated in a consensus statement.
