Acute illness in children with secondary adrenal insufficiency

Abstract

Objective and background: Secondary adrenal insufficiency (SAI) is a rare conditioning childhood which can be associated with high levels of morbidity in some patients. The causes of increased levels of illness are not well defined and warrant further investigation.

Methods: A retrospective cohort of patients with SAI was constructed by examining records of all attendances for acute illness by SAI patients at the emergency department of the two specialist paediatric hospitals in Sydney, Australia between 2004and 2016. Demographic, clinical, and physiological characteristics together with pre-hospital illness management strategies were assessed.

Results: There were 168 presentations for an acute illness by 47 children with SAI. Comorbid diabetes insipidus (DI) was present in 46.8% (n = 22), 77.3% (n = 17) of whom were male (P < .05). Patients with comorbid DI were more likely to be admit-ted (86.7%, n = 65 vs 60.2%, n = 56 for non-DI, P < .01); had a longer hospital stay(6.5 (8.7) vs 2.5 (2.6) days, P < .001); and higher rates of IV HC administration (56.0%,n = 42 vs 35.5%, n = 33), P < .01). The medically-diagnosed adrenal crisis (AC) rate was3.68 ACs/100PY. Stress dose use was reported by fewer DI patients (58.7%, n = 44)than non-DI patients (78.5%, n = 73, P < .01). Previous attendance at hospital was positively associated with stress dose use (OR = 1.08, 95% CI 1.00, 1.16).

Conclusion: Secondary adrenal insufficiency can cause significant morbidity in children. Comorbid DI is associated with higher levels of hospitalisation, longer hospital stays and lower levels of pre-emergent stress dose use. Educational interventions in this subgroup of SAI patients may reduce the burden of morbidity
