Abstract

Summary: Adrenal insufficiency is a rare cause of hypercalcaemia and should be considered when more common causes such as primary hyperparathyroidism and malignancy are excluded. Opioid therapy as a cause of adrenal insufficiency is a possibly under-recognised endocrinopathy with potentially life-threatening adverse effects. We report on a case of opioid-induced secondary adrenal insufficiency presenting as hypercalcaemia. The patient was a 25-year-old man who developed hypercalcaemia during the recovery stage after a period of critical illness. Systematic investigation of his hypercalcaemia found it to be due to secondary adrenal insufficiency, developing as a consequence of methadone opioid analgesia. Treatment with i.v. saline and subsequent glucocorticoid replacement led to resolution of the hypercalcaemia. The hypoadrenalism resolved when opioids were subsequently weaned and ceased. These two interacting endocrinopathies of opioid-induced adrenal insufficiency and consequent hypercalcaemia highlight the importance of maintaining awareness of the potentially serious adverse clinical outcomes which can occur as a result of opioids, particularly considering that symptoms of hypoadrenalism can overlap with those of concomitant illness. Treatment with hydration and glucocorticoid replacement is effective in promptly resolving the hypercalcaemia due to hypoadrenalism. Hypoadrenalism due to prescribed and recreational opioids may be more common than is currently recognised. Learning points: Opioid therapy can cause clinically significant secondary adrenal insufficiency, and this may be more common than is currently recognised. Adrenal insufficiency is reversible after discontinuation of the opioid therapy. Hypercalcaemia can occur as a consequence of adrenal insufficiency, and may be the presenting feature. Treatment of hypercalcaemia due to adrenal insufficiency involves i.v. saline and glucocorticoid replacement.

  • Less common but well-recognized manifestations of cortisol deficiency include hypercalcemia and hypoglycemia.

    “As well as common symptoms of cortisol deficiency, such as fatigue, nausea/vomiting, musculoskeletal pain, weight loss, headache, and light-headedness (119), less common but well recognized manifestations, such as hypercalcemia (123) and hypoglycemia (124) have been described.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
