Symptomatic glucocorticoid-induced adrenal suppression in the United Kingdom and Ireland: a BPSU study.

Abstract

Objective: To determine the incidence and describe the presentation and management of unexpected symptomatic glucocorticoid-induced adrenal suppression (AS) in children and young people aged 0-15 years.

Setting and design: Surveillance study of symptomatic glucocorticoid (GC)-induced AS with supportive biochemical evidence or presenting as an adrenal crisis, reported via the British Paediatric Surveillance Unit (BPSU) from September 2020 to September 2022.

Results: Over a 25-month period, 190 reports of symptomatic GC-induced AS/adrenal crisis were made, of which 22 were confirmed cases: 18 AS and 4 adrenal crises. This translates to an incidence rate of 0.09 new cases of GC-induced AS per 100 000 children aged 0-15 per year in the UK. There was a broad range of underlying diagnoses requiring GC prescription (16) and GC preparations (13). Of the 22 patients, 7 had more than 1 type of GC prescribed. The administration of oral GC occurred in 19 of the cases, inhaled GC use in 7, topical use in 5 and 1 case occurred after a single intramuscular injection of GC. All patients were discussed with a paediatric endocrinology team.

Conclusions: The incidence of AS from this UK-based BPSU study is lower than a similar Canadian study. This may indicate that paediatricians in the UK and Ireland are becoming more aware of the potential for GC-induced AS and thus are more proactive to prevent its occurrence. The clinical cases still highlight the need to educate families and healthcare professionals with a view to further reducing the morbidity and potential mortality associated with GC-induced AS.
