Much to be desired in self-management of patients with adrenal insufficiency.

We assessed self-management in patients with adrenal insufficiency and patient-related factors that affect self-management. A self-report questionnaire was developed to assess self-management. The questionnaire contained three main topics, including: (i) medication adherence; (ii) anticipated measures; and (iii) dose adaptation during medical emergencies. Sixty per cent of the patients (n = 116) completed the questionnaire. The score for the medication adherence was 3.5 out of 4. The score for anticipated measures was 3.4 out of 5, and dose adaptation during medical emergencies was 1.9 out of 3. Older age was a positive predictor for all three self-management topics. The female sex was a positive predictor for anticipated measures and dose adaptation during medical emergencies. High education level was associated with higher scores on dose adaptation during medical emergencies in women, not in men. Education level did not affect other self-management aspects. There seems to be a need to improve self-management in these patients. Self-management might be improved by continuous education, and involvement of endocrine nurses and nurse practitioners is likely to be a key factor in the effectiveness of patient education.

Dextroamphetamine Treatment in Children With Hypothalamic Obesity.

Introduction: Hypothalamic obesity (HO) in children has severe health consequences. Lifestyle interventions are mostly insufficient and currently no drug treatment is approved for children with HO. Amphetamines are known for their stimulant side-effect on resting energy expenditure (REE) and suppressing of appetite. Earlier case series have shown positive effects of amphetamines on weight in children with acquired HO. We present our experiences with dextroamphetamine treatment in the, up to now, largest cohort of children with HO. Methods: A retrospective cohort evaluation was performed of children with HO treated with dextroamphetamine at two academic endocrine pediatric clinics. Off-label use of dextroamphetamine was initiated in patients with progressive, therapy-resistant acquired or congenital HO. Anthropometrics, REE, self-reported (hyperphagic) behavior and energy level, and side effects were assessed at start and during treatment. Results: Nineteen patients with a mean age of 12.3 ± 4.0 years had been treated with dextroamphetamine. In two patients, ΔBMI SDS could not be evaluated due to short treatment duration or the simultaneous start of extensive lifestyle treatment. Mean treatment duration of the 17 evaluated patients was 23.7 ± 12.7 months. Fourteen patients (n = 10 with acquired HO, n = 4 with congenital HO) responded by BMI decline or BMI stabilization (mean ΔBMI SDS of -0.6 ± 0.8, after a mean period of 22.4 ± 10.5 months). In three patients, BMI SDS increased (mean ΔBMI SDS of +0.5 ± 0.1, after a mean period of 29.7 ± 22.6 months). In 11 responders, measured REE divided by predicted REE increased with +8.9%. Thirteen patients (68.4%) reported decreased hyperphagia, improvement of energy level and/or behavior during treatment. Two patients developed hypertension during treatment, which resulted in dosage adjustment or discontinuation of treatment. Twelve children continued treatment at last moment of follow-up. Conclusion: In addition to supportive lifestyle interventions, dextroamphetamine treatment may improve BMI in children with HO. Furthermore, dextroamphetamines have the potential to decrease hyperphagia and improve resting energy expenditure, behavior, and energy level. In patients with acquired HO, these effects seem to be more pronounced when compared to patients with congenital HO. Future studies are needed to support these results.

We mind your step: understanding and preventing drop-out in the transfer from paediatric to adult tertiary endocrine healthcare.

Introduction: Transition from paediatric to adult endocrinology can be challenging for adolescents, their families and healthcare professionals. Previous studies have shown that up to 25% of young adults with endocrine disorders are lost to follow-up after moving out of paediatric care. This poses a health risk for young adults, which can lead to serious and expensive medical acute and long-term complications. Methods: In order to understand and prevent dropout, we studied electronic medical records of patients with endocrine disorders. These patients were over 15 years old when they attended the paediatric endocrine outpatient clinic (OPC) of our hospital in 2013-2014 and should have made the transfer to adult care at the time of the study. Results: Of 387 adolescents, 131 had an indication for adult follow-up within our university hospital. Thirty-three (25%) were lost to follow-up. In 24 of them (73%), the invitation for the adult OPC had never been sent. We describe the failures in logistic processes that eventually led to dropout in these patients. Conclusion: We found a 25% dropout during transfer from paediatric to adult tertiary endocrine care. Of all dropouts, 73% could be attributed to the failure of logistic steps. In order to prevent these dropouts, we provide practical recommendations for patients and paediatric and adult endocrinologists.

Adrenal function in adult long-term survivors of nephroblastoma and neuroblastoma.

BACKGROUND: Adrenal insufficiency, or relative insufficiency, might partly explain increased mortality rates in nephroblastoma and neuroblastoma survivors after unilateral adrenalectomy. OBJECTIVE: To assess adrenal function and its metabolic effects in survivors after adrenalectomy. METHODS: In this cross-sectional study, 67 adult long-term survivors of nephroblastoma, 36 survivors of neuroblastoma and 49 control subjects participated. Adrenal function was assessed by a 1µg short Synacthen-test. Levels of cortisol, adrenocorticotrophic hormone (ACTH), low (LDL-C) and high-density lipoprotein-cholesterol (HDL-C), triglycerides, apolipoprotein-B, glucose and insulin were assessed in blood samples taken at baseline. In addition, cortisol levels were assessed after 30 (t=30) and 60 min. Homoeostatic Model Assessment (HOMA) was calculated. RESULTS: Adrenal insufficiency was not present in survivors. Interestingly, baseline serum cortisol levels were higher in survivors after unilateral adrenalectomy (mean 503 nmol/l) (N=46) than in survivors with both adrenals intact (mean 393 nmol/l, P=0.002) (N=52), and than in controls (mean 399 nmol/l, P=0.013) (N=49). After correcting for age, sex and use of oral oestrogens, unilateral adrenalectomy was independently associated with elevated baseline cortisol and ACTH levels. Baseline cortisol levels were positively associated with triglycerides (P<0.001), LDL-C (P=0.004), apolipoprotein-B (P<0.001) and HOMA (P=0.008). CONCLUSIONS: No adrenal insufficiency was observed in survivors of nephroblastoma and neuroblastoma. Survivors treated with unilateral adrenalectomy had relatively high basal cortisol and ACTH levels, indicating a higher central setpoint of the hypothalamic-pituitary-adrenal axis. This higher setpoint was associated with lipid concentrations and insulin resistance and can therefore influence the cardiovascular risk profile in long-term survivors of nephroblastoma and neuroblastoma.
