Alterations in resting-state functional connectivity in patients with congenital adrenal hyperplasia

Messina Valeria , van´t Westeinde Annelies , Padilla Nelly , Lajic Svetlana ,

Background: Patients with congenital adrenal hyperplasia (CAH) are treated with life-long glucocorticoid (GC) replacement therapy. Negative effects on cognition, brain structure and function during working memory tasks have been identified. To date, no studies on functional connectivity during rest have been performed in patients with CAH. One study conducted on patients with CushingÂ’s syndrome, another disorder of cortisol imbalance, suggests that long-t...

Increased resting-state functional connectivity in the medial orbitofrontal cortex of patients with autoimmune Addison's disease

van't Westeinde Annelies , Padilla Nelly , Bensing Sophie , Lajic Svetlana

Background: Patients with autoimmune Addison’s disease (AAD) lack production of glucocorticoids (GCs), mineralocorticoids (MCs) and androgens from the adrenal gland, due to autoimmune destruction of its cortex. Patients require replacement of GCs and MCs for the rest of their lives. In some cases, testosterone is supplemented in females. Brain function is sensitive to fluctuations in cortisol and may therefore be affected in AAD due to long-term disturba...

Long-term Effects of Prenatal Dexamethasone Treatment and Postnatal Glucocorticoid Treatment on Brain Structure in the Context of CAH

Westeinde Annelies van't , Karlsson Leif , Sandberg Malin , Nordenstrom Anna , Paddila Nelly , Lajic Svetlana

Objective: Congenital Adrenal Hyperplasia (CAH) requires life-long replacement of cortisol. Female fetuses with classical CAH are virilized, which can be prevented by prenatal dexamethasone (DEX) treatment from gestational week 7. However, 7 out of 8 fetuses are treated unnecessarily during fetal life and are thus exposed to high prenatal glucocorticoid (GC) levels. Both prenatal exposures to high GC levels, as well as long term postnatal GC-treatment in patients with CAH are ...

Brain activity during working memory in congenital adrenal hyperplasia

van’t Westeinde Annelies , Zimmermann Marius , Messina Valeria , Karlsson Leif , Padilla Nelly , Lajic Svetlana ,

Objective: Congenital Adrenal Hyperplasia (CAH) requires life-long replacement of cortisol. However, this long-term GC-treatment could change the developmental trajectory of the brain and predispose patients to problems with cognition and mood regulation. Previously, we have found impairments in working memory in patients with CAH, as well as alterations in brain structure in regions of the central executive network (CEN). These changes could be associated wit...

Emotion regulation in congenital adrenal hyperplasia

van’t Westeinde Annelies , Zimmermann Marius , Savic Ivanka , Lajic Svetlana ,

Objective: Oral hydrocortisone medication for Congenital Adrenal Hyperplasia (CAH) could lead to suboptimal blood cortisol levels throughout the day. In addition, the HPA-axis is rendered inflexible in patients. Cortisol is crucially involved in the stress response as well as in generating and regulating emotional responses to stimuli. Sub-optimal cortisol levels, in combination with a less flexible HPA-axis, could therefore lead to problems with emotion regul...

Non-Immune Diabetes Mellitus and Neurodegeneration: Two Distinct Cases of Wolfram Syndrome

Lemay Annelies , Sinnema Margje , den Brinker Marieke , Dotremont Hilde , France Annick , Rooman Raoul , Straetemans Saartje

Background: Wolfram syndrome features diabetes insipidus, diabetes mellitus, optic nerve atrophy, and deafness (DIDMOAD). Especially the neurological degeneration usually leads to a very poor prognosis. We present two cases of Wolfram syndrome, an autosomal dominant and an autosomal recessive type, caused by heterozygous mutations in the WFS1 gene.Case report: Case 1: a 13-year-old girl with a history of progressive sensorineuronal hearing loss ...

Pseudohypoparathyroidism: Clinical Heterogeneity Illustrated by Three Different Cases

Lemay Annelies , den Brinker Marieke , Dotremont Hilde , Ceulemans Berten , France Annick

Background: Pseudohypoparathyroidism represents a group of clinical and molecular heterogeneous disorders, characterized by functional hypoparathyroidism, caused by end-organ resistance to the action of PTH. Pseudohypoparathyroidism manifests as hypocalcemia, hyperphosphatemia and elevated plasma levels of PTH. A combination of features, also known as Albright osteodystrophy including disproportionate short stature, obesity, dysmorphia, may co-exist.Case...

How to Recognize Underlying Somatic Causes of Paediatric Obesity? Performance of the Diagnostic Recommendations of the Endocrine Society Guideline and Suggestions for Improvement

Abawi Ozair , Kleinendorst Lotte , van der Voorn Bibian , Brandsma Annelies , van Rossum Elisabeth , van Haelst Mieke , van den Akker Erica

Background: Underlying causes of obesity are thought to be rare even in specialized paediatric endocrinology clinics. However, evidence is limited. The Endocrine Society (ES) guideline for paediatric obesity makes the following diagnostic recommendations: endocrine evaluation in presence of reduced growth velocity, evaluation of cerebral obesity in presence of CNS injury, re-evaluation of drug choice in patients using antipsychotics. Genetic testing is recomme...

Bilateral testicular regression: genetic etiology and outcome in a large Belgian series

Background: Bilateral testicular regression (BTR) is characterized by the absence of both testicles in a newborn male or shortly thereafter, and presenting as bilateral cryptorchidism with undetectable AMH levels and the absence of Müllerian structures on pelvic ultrasound. Depending on when the regression occurs during fetal development, the condition can be associated with a micropenis. Few studies have explored the etiology and long-term outcome of BTR...

Introduction: Among children with short stature, some show persistent IGF-I levels <-2.0 SDS despite a normal growth hormone (GH) response in a stimulation test. This may be caused by conditions that could benefit from recombinant human GH (rhGH) therapy (e.g. GH neurosecretory dysfunction, bioinactive GH, partial GH insensitivity). Therefore, the IGF-I generation test (IGFIGT) was implemented in 2006 using a national, standardized protocol. Children with a...
