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.
SummaryAlternating between hyper- and hypo-thyroidism may be explained by the simultaneous presence of both types of TSH receptor autoantibodies (TRAbs) – thyroid stimulating autoantibodies (TSAbs) and TSH blocking autoantibodies (TBAbs). It is a very rare condition, particulary in the pediatric age. The clinical state of these patients is determined by the balance between TSAbs and TBAbs and can change over time. Many mechanisms may be involved in fluctuating thyroid function: hormonal supplementation, antithyroid drugs and levels of TSAbs and TBAbs. Frequent dose adjustments are needed in order to achieve euthyroidism. A definitive therapy may be necessary to avoid switches in thyroid function and frequent need of therapeutic changes. We describe an immune-mediated case of oscillating thyroid function in a 13-year-old adolescent. After a short period of levothyroxine treatment, the patient switched to a hyperthyroid state that was only controlled by adding an antithyroid drug.Learning points Autoimmune alternating hypo- and hyper-thyroidism is a highly uncommon condition in the pediatric age.It may be due to the simultaneous presence of both TSAbs and TBAbs, whose activity may be estimated in vitro through bioassays.The clinical state of these patients is determined by the balance between TSAbs and TBAbs and can change over time.The management of this condition is challenging, and three therapeutic options could be considered: I-131 ablation, thyroidectomy or pharmacological treatment (single or double therapy).Therapeutic decisions should be taken according to clinical manifestations and thyroid function tests, independent of the bioassays results.A definitive treatment might be considered due to the frequent switches in thyroid function and the need for close monitoring of pharmacological treatment. A definitive treatment might be considered due to the frequent switches in thyroid function and the need for close monitoring of pharmacological treatment.
Background Postprandial hyperglycemia is one of the biggest challenges in children with type 1 diabetes (T1D). Ultra-fast-acting aspartic insulin (faster aspart) has a quicker onset of action and an earlier maximum activity. The aim of this study is to analyze the impact of faster aspart in metabolic control of pediatric patients with T1D in a “real-world” setting. Methods Retrospective analysis of 60 pediatric patients with T1D who changed their insulin analogue to faster aspart. Anthropometric data, insulin doses, capillary and interstitial glucose recordings and average glycated hemoglobin before and after insulin analogue’s switch were obtained. After all population analyses, patients were analyzed separately according to the type of treatment, multiple daily injections (MDI) and continuous subcutaneous insulin infusion (CSII), and according to age group. Results Faster aspart significantly improved metabolic control, increasing time in range (TIR) (42 vs.54%, respectively; P = 0.007) and decreasing time above range (TAR) (52 vs.40%, respectively; P = 0.009), without an increased time in hypoglycemia (7% before and after faster aspart’s introduction; P = 0.933). This was reassured in the adolescent years ( n = 45), with an increase in TIR (37 vs. 47%, respectively; P = 0.034) and decrease in TAR (51 vs. 45%, respectively; P = 0.022). Patients on CSII ( n = 47), also demonstrated an increase in TIR (38 vs. 50%, respectively; P = 0.010). The reduction of A1c was not statistically significant. Conclusion Although the advantage of faster aspart had already been demonstrated in pediatric patients under MDI, “real-world” studies, including patients under CSII, are still lacking. This study highlights the important impact of faster aspart on metabolic control in children with T1D, particularly among adolescents under CSII.
Limbic encephalitis is a rare neurological disorder that may be difficult to recognize. Clinical features include memory impairment, temporal lobe seizures and affective disturbance. We report the case of a 10-year-old girl with type 1 diabetes mellitus that presented with seizures, depressed mood and memory changes. The diagnosis of glutamic acid decarboxylase 65 (GAD65) mediated limbic encephalitis relied on cerebral magnetic resonance imaging lesions and high serological and cerebrospinal fluid GAD65-antibodies titers. High-dose steroidal therapy was started with clinical improvement. Relapse led to a second high-dose steroid treatment followed by rituximab with remission. A correlation between serum GAD65-antibodies levels and symptoms was found, demonstrating GAD65-antibodies titers may be useful for clinical follow-up and immunotherapy guidance. This report raises awareness of this serious neurological condition that may be associated with type 1 diabetes, underlining the importance of an early diagnosis and prompt treatment for a better prognosis.
