Brain MRI in Evaluation of Endocrine Diseases of Childhood: Causal and Incidental Lesions

Selbonne Emilie , Martinerie Laetitia , Leger Juliane , Elmaleh Monique , Sebag Guy , Carel Jean-Claude

Background: Brain MRI is an essential tool in the diagnosis of neuroendocrine disorders and aims at detecting anatomical abnormalities and tumors. However, it may lead to the identification of unrelated or questionably related abnormalities in the hypothalamic-pituitary region and/or the rest of the brain parenchyma.Objective and hypotheses: To establish the prevalence of causal lesions on brain MRI of children evaluated for hypopituitarism, assess the f...

Follow-up to Adulthood of Two 46,XY Siblings with 5-alpha Reductase Deficiency and Different Sex of Rearing

Chiniara Lyne , Sandberg David , Van Vliet Guy

Background: 46,XY patients with 5α-reductase deficiency (5-ARD), reared from birth as girls, are reported to self-reassign as boys subsequent to a masculinizing puberty; whether this holds true in cases of early orchidectomy is less well documented.Objective and hypotheses: Prepubertal orchidectomy reduces the likelihood of gender self-reassignment.Method: Presentation, management and outcome of two siblings with 5-ARD with na...

Insulin Resistance and Impaired Glucose Tolerance in Overweight/Obese Adolescents Attending an Obesity Clinic in Belgium

Zeevaert Renate , Faust Kelly , Otte Trui , Vanhaesebrouck Sigrid , Massa Guy

Background: Obesity is a global epidemic and major health concern. Studies on insulin resistance and glucose abnormalities in European overweight/obese adolescents are rare.Aim: To study prevalence of insulin resistance, impaired glucose tolerance and type 2 diabetes mellitus in a cohort of overweight/obese adolescents. To determine correlations between patient characteristics and biochemical parameters of glucose homeos...

Batch-to-Batch Consistency of a Highly O-Glycosylated Long-Acting Human Growth Hormone (MOD-4023)

Moschcovich Laura , Guy Rachel , Felikman Yana , Zakar Miri , Hershkovitz Oren

Background: OPKO Biologics is a clinical-stage public company developing long-acting therapeutic proteins utilizing CTP technology. The technology involves fusion of the C-terminal peptide of human chorionic gonadotropin (hCG), which is highly O-glycosylated, to the target protein. CTP enabled the production of a long-acting human growth hormone (hGH) (MOD-4023), which supports a single weekly injection in growth hormone-deficient patients. MOD-4023 is manufactured as a non-vi...

Characterization of MOD-4023 Glycosylation, a CTP Modified Long Acting GH in Advanced Clinical Stages

Herskovitz Oren , Moschovich Laura , Guy Rachel , Felikman Yana , Fima Eyal

Background: Prolor Biotech, Inc. is a clinical stage public company developing long acting therapeutic proteins utilizing a technology called CTP. The technology involves fusion of the C-terminus peptide of hCG, which is a highly O-glycosylated peptide, to the target protein. Manufacturing process was developed to generate a reproducible highly glycosylated CTP-modified long-acting hGH (MOD-4023), which supports a single weekly injection in GH deficient patients. MOD-...

Goliath, a Variant of DAVID Syndrome?

Hasselmann Caroline , Samuels Mark E , Van Vliet Guy

Background: DAVID syndrome (deficit in anterior pituitary function and variable immune deficiency) (J Clin Endocrinol Metab 97 E121, 2012) can be caused by NFKB2 mutations (Am J Hum Genet 93 13, 2013). All patients have an orthotopic posterior pituitary (PP) and most only ACTH deficiency.Objective and Hypothesis: To describe a girl with common variable immunodeficiency (CVID), ectopic PP (EPP) ...

Contrasting Central Diabetes Insipidus due to preproAVP Mutations: Earlier Onset of Symptoms in Recessive than in Dominant Forms

Bourdet Karine , Valette Sophie , Deladoey Johnny , Vliet Guy Van

Background: Central diabetes insipidus may result from mutations in the preproAVP gene, most often heterozygous and occurring de novo or inherited in an autosomal dominant mode; in these cases, intracellular accumulation of the misfolded product of the mutated allele slowly destroys the AVP-producing neurons, so that the onset of symptoms may be delayed for up to 28 years by which time the posterior pituitary hyperintense signal is no longer visible on magnetic resonance imagi...

The Triglyceride-to-HDL Cholesterol Ratio is Associated with Insulin Resistance in Obese Boys But Not in Obese Girls

Massa Guy , Bervoets Liene , Massa Jonas , Zeevaert Renate

Background: Children and adolescents with obesity often have insulin resistance (IR) and are at increased risk to develop coronary heart disease (CHD) in adulthood. The triglyceride to HDL-cholesterol (TG/HDL-C) ratio reflects small, dense low-density lipoprotein (LDL), an atherogenic lipoprotein particle that strongly predicts CHD.Objective and hypotheses: To evaluate the TG/HDL-C ratio in obese children and adolescents and study the relationship with a...

Two pedigrees with congenital bilateral anorchia in one sibling and testicular torsion at adolescence in another: a shared genetic predisposition?

Brachet Cécile , Chiniara Lyne , Vliet Guy Van

Background: In bilateral anorchia or vanishing testes syndrome, testicular function is normal during the embryonic period, as shown by the absence of Müllerian remnants and of hypospadias. Although normally differentiated, the penis may be small due to decreased testosterone secretion during the fetal period. In a normally virilised boy with non-palpable testes, with or without micropenis, the diagnosis is established by undetectable plasma anti-Müllerian hormone (AM...

Neonatal TSH screening for congenital hypothyroidism: before discharge or at home?

Boros Emese , Marcelis Lionel , Van Vliet Guy , Elilie Mawa Ongoth Farel , Heinrichs Claudine , Brachet Cecile

In Belgium, neonatal TSH screening for congenital hypothyroidism has been performed between day 3 and 5 of life since the late seventies. In January 2015, a policy of early discharge of healthy neonates was implemented so that the neonatal screening strategy had to be adapted. Between January 2015 and September 2019, dried blood spot sampling was mostly collected at home AFTER discharge at 72 h of life (Newborn Screening Strategy 1 (NBS1)). After October 2019, sampling was mos...
