고칼슘혈증의 빈도 및 원인 (1) - 입원환자를 대상으로 -

Abstract

To evaluate the incidence and causes of hypercalcemia in a hospital po;ulation in korea, all 7332 patients in the Dong San Medical Center hospital between June and December 1992 were evaluted for plasma calcium and plasma phosphate, albumin. We defined hypercalcemia as plasma calcium concentration above 2.40 mmol/L adjusted for albumin. Plasma calcium above 2.40 mmol;L was found in 192 (2.6%). The main causes of hypercalcemia were malignancy (30.3%), immobilization (26.9%), diuretics(thaizide) (10.9%), chronic renal failure(9.2%), and primary hyperparathyroidism(3.4%). The remainders were unknown carses(73 patients). In malignancy as a cause of hypercalcemia, lung cancer was the most common(27.7%). We concluded that malignancy is the most common cause of hypercalcemia and the primary hyperparathyroidism is relatively uncommon in admitted patients.(J Kor Soc Endocrino 8:72~77, 1993)
