Takeaway

  • The risk of mortality was significantly higher in patients with adrenal insufficiency compared with control participants, regardless of the glucocorticoid replacement agent.

  • Mortality risk relative to their matched control participants was higher in patients with primary adrenal insufficiency taking prednisolone vs hydrocortisone.

Why this matters

  • As prednisolone has a longer duration of action and is relatively cheaper, it is recommended as an alternative to hydrocortisone for patients with adrenal insufficiency.

  • However, mortality risk with the 2 glucocorticoid replacement agents needs investigation.

Study details

  • This retrospective study included 6821 patients with adrenal insufficiency (primary, n=2052; secondary, n=3948) from a UK primary care database treated with an oral glucocorticoid, i.e., hydrocortisone, cortisone acetate, prednisolone or prednisone.

  • Patients with adrenal insufficiency were matched 1:10 with age-, sex- and GP-matched control participants.

  • Funding: None.

Key results

  • Overall, 62% and 18% of patients with adrenal insufficiency were treated with hydrocortisone and prednisolone, respectively.

  • The risk of mortality was higher in patients receiving prednisolone (adjusted HR [aHR], 1.75; 95% CI, 1.53-2.00) or hydrocortisone (aHR, 1.70; 95% CI, 1.58-1.83) vs control participants.

  • In patients with primary adrenal insufficiency, prednisolone use was associated with higher mortality risk relative to control participants vs hydrocortisone (aHR, 2.87 vs 1.92; P=.004).

  • This difference was not observed in secondary adrenal insufficiency (P=.69).

Limitations

  • The proportion of patients with primary adrenal insufficiency treated with prednisolone was small.

  • Cause of death and glucocorticoid dosages were not considered in the analysis.
