Background: Adrenal insufficiency (AI) is a life-threatening disease characterized by deficient production of glucocorticoids and/or mineralocorticoids. It is caused by primary or secondary/tertiary adrenal failure. Prompt diagnosis and management are essential and may even be life-saving. Methods: We retrospectively collected clinical, laboratory and radiological data from AI patients observed over 34 years (1984–2017) in a pediatric endocrinology department of a tertiary care hospital. Results: Seventy AI patients were identified: 59% with primary adrenal insufficiency (PAI) and 41% with central adrenal insufficiency (CAI). PAI patients were diagnosed at 1.5 ± 4.4 years and followed for 11.6 ± 6.2 years; 85% had classical congenital adrenal hyperplasia (CAH) and 7% had autoimmune PAI. At presentation, 73% had hyponatremia and more than half had mucocutaneous hyperpigmentation, asthenia, anorexia, weight loss, nausea and vomiting. All the patients were treated with hydrocortisone and 90% were also on fludrocortisone. Regarding CAI patients, they were diagnosed at 5.4 ± 5.0 years and they were followed for 9.6 ± 6.4 years; craniopharyngioma was present in 31% of the cases and 14% had pituitary hypoplasia. Besides corticotropin, thyrotropin (93%), growth hormone (63%) and antidiuretic hormone (52%) were the most common hormone insufficiencies. The most frequent manifestations were hypoglycemia (34.5%), nausea/vomiting (27.6%) and infectious diseases (27.6%); all the patients were treated with hydrocortisone. Conclusions: Despite medical advances, the diagnosis and management of AI remains a challenge, particularly in the pediatric population. Raising awareness and knowledge in medical teams and population about the disease is of crucial importance to improve clinical outcomes and to reduce disease morbidity/mortality.
