title: Hypercalcaemia in acute adrenal insufficiency. A case report.
abstract: A woman aged 62 developed a septic shock and pulmonary embolism after skin grafting for extensive burns. She was put on anticoagulants. A second shock led to renal insufficiency. Hypercalcaemia developed. A CT scan of the upper abdomen disclosed enlarged adrenal glands. An acute adrenal haemorrhage was suspected. The levels of cortisol were low in the plasma and urine and did not respond to ACTH stimulation. Cortisone replacement therapy improved the condition of the patient and normalized plasma calcium levels. The mechanisms of hypercalcaemia in acute adrenal insufficiency are discussed. Multiple factors have been proposed: haemoconcentration, an increased affinity of plasma proteins for calcium, an increase in the filtrable calcium complexes, and an enhanced calcium mobilization of skeletal origin.
