GLUCOCORTICOID-INDUCED ADRENAL INSUFFICIENCY: A STUDY OF THE INCIDENCE IN HOSPITAL PATIENTS AND A REVIEW OF PERI-OPERATIVE MANAGEMENT

Abstract

Objective: Glucocorticoid (GC) pharmacotherapy is an effective treatment for a range of diseases, but exposure can suppress the hypothalamic-pituitary-adrenal axis, leading to glucocorticoid-induced adrenal insufficiency (GC-AI) in some patients. However, the incidence of diagnosed GC-AI and the associated health burden, including the incidence of adrenal crises (ACs), are unknown. Although GC-AI treatment is based on well-established principles, there are no agreed protocols regarding the peri-operative management of exposed patients. The aims of this study were to assess the incidence of diagnosed GC-AI in hospital patients and review current approaches to peri-operative management of surgical patients with GC exposure.

Methods: An analysis of hospital admission data concerning adult patients diagnosed with GC-AI and a review of published recommendations for peri-operative GC cover.

Results: Between 2001 and 2013, admission with a diagnosis of GC-AI in New South Wales, Australia was rare (annual average of 22.5 admissions/year) and ACs were even more rare (n = 3). Almost two-thirds (64.4%, n = 188) of the patients with diagnosed GC-AI were aged between 50 and 79 years and 45.2% (n = 132) had a comorbid infection. The current approach to peri-operative management of patients with GC exposure appears to be influenced by both the absence of clear guidelines and historic practices. This results in the exposure of some patients to supraphysiologic doses of GCs during the peri-operative period.

Conclusion: Hospital admission with a diagnosis of GC-AI (with or without an AC) is very rare. Clear guidelines on peri-operative GC cover are necessary to avoid overreplacement with supraphysiologic doses in susceptible patients. (Endocr Pract. 2018;24:437-445)
