[Hypercalcemia in the elderly].

UNLABELLED

A COMMON FINDING: Hypercalcemia is not rare among elderly patients. Hyperparathyroidism and neoplasia are the most frequent causes of hypercalcemia in old patients. Symptoms due to hypercalcemia are usually non specific in old subjects, leading to consider easily this diagnosis and to measure plasma calcium level.

DIAGNOSIS

Biological diagnosis of hypercalcemia is not always obvious in old patients because of frequently decreased plasma albumin levels leading to lower plasma total calcium level. Thus, it is always necessary to calculate plasma total calcium level corrected by albumin in order not to underestimate hypercalcemia in elderly subjects.

PROGNOSIS

The short-term risk of hypercalcemia is acute hypercalcemia, which may be lifethreatening. The long-term risk of hypercalcemia is renal failure.

TREATMENT

When hypercalcemia is due to primary hyperparthyroidism, the treatment of choice is surgery. However, for old patients with high surgical risk surgery with local anesthesia or ultrasonically guided percutaneous ethanol injection into parathyroid adenoma can be proposed.
