Unexpected impact of sex hormones on B-cells in trans- and cis-gendered healthy young people

Peckham Hannah , Rosser Elizabeth C , Radziszewska Anna , Robinson George , Martin-Gutierrez Lucia , De Gruijter Nina M , Jury Elizabeth C , Butler Gary E , Ciurtin Coziana ,

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...

Treatment-resistant hypokalemia and arterial hypertension: a prismatic case of low renin childhood hypertension

Rakicioglu H. , Kamrath C. , Genthner N. , Karatsiolis P. , Reincke M. , A. wudy S.

We report on a 17-year-old female patient with cramps in hands and legs since 6 months. She showed hypokalemia with high need of potassium substitution (128mmol K= 1.3 mmol/kg/d), arterial hypertension (mean 154.5/92 mmHg), polydipsia and polyuria without nocturia or salt craving. Her PMH revealed neuroblastoma stage III with high-dose chemotherapy, stem cell transplantation and obesity (36.8 kg/m2). Further investigation showed aldosterone 77.5 ng/dl (norm values: 2-10ng/dl),...

Spatial navigation and memory in transgender male adolescents treated with gender affirming hormones

Perl Liat , Oren Asaf , C. Mueller Sven , Raphael Ido , Borger Ophir , Sheppes Tamar , Shechner Tomer

Background: Spatial navigation is an essential human skill that helps individuals track their changes in position and orientation by integrating self-motion cues. Meta-analyses indicate that males, on average, perform better than females on a number of spatial tasks. Sex steroids, mainly androgens, modulate the remodeling of synapses in the prefrontal cortex and hippocampus, a limbic brain area with critical influence on spatial and contextual memory. Androgen...

Extreme Short Stature and Poor Pubertal Growth: When FBN1 is the Culprit

Brachet Cécile , Boros Emese , Soblet Julie , Vilain Catheline , Heinrichs Claudine

Introduction: Very short stature is a common presenting complain that gives rise to numerous investigations. FBN1 heterozygous mutations cause acromelic dysplasia syndromes. The phenotypic spectrum of these growth disorders is broad, ranging from short stature with short extremities, stiff joints, skin thickening with tracheal stenosis and cardiac valvulopathy to nearly isolated short stature. Here, we report on a girl with disproportionate short stat...

Bone Age Advancement in Prepubertal Children with Premature Adrenarche

Santos-Silva Rita , Costa Carla , Castro-Correia Cíntia , Fontoura Manuel

Introduction: Premature adrenarche (PA) is usually define as the appearance of clinical signs of androgen action before the age of 8 years in girls and 9 years in boys, associated the serum DHEAS above 40µg/dl.Aims: 1) To characterize a population of prepubertal children with PA regarding birth weight, anthropometry, growth velocity, height difference, bone age, IGF1 and DHEAS. 2) To compare IgF1, bone age, growth v...

Differences Between Normal-bmi Girls with Premature Adrenarche and Overweight or Obese Girls with Premature Adrenarche

Santos-Silva Rita , Costa Carla , Castro-Correia Cíntia , Fontoura Manuel

Introduction: There seems to be an undoubting, but still puzzling, relationship between obesity and premature adrenarche (PA).Aim: To characterize a population of prepubertal girls with PA and to compare girls with a normal body mass index (BMI) with girls who are overweight or obese, in what regards gestational age and birth weight, age at the referral, clinical signs, anthropometry, bone age and hormone profile.<p ...

Heterozygous OTX2 Deletion in a Boy with Normal Eye Development and Normal Pituitary Function

Boros Emese , Boitsios Gramatina , Vilain Catheline , Balikova Irina , Heinrichs Claudine , Brachet Cécile

Introduction: Orthodenticle homeobox 2 (OTX2) is a transcription factor that plays a critical role in brain and eye development. Heterozygous deleterious mutations in this gene lead to eye malformation such as anophthalmia, microphthalmia, coloboma or optic nerve hypoplasia, normal or hypoplastic pituitary gland and normal or ectopic posterior pituitary gland with isolated growth hormone deficiency or combined pituitary hormone deficiency. There is no...

Complexities of Diagnosis in 17-Beta-Hydroxysteroid Dehydrogenase Deficiency and Implementation of Next Generation Sequencing in Guiding Management Decisions – Case Series of Six Patients

Taylor-Miller Tashunka , Barton John S , Burren Christine P , Woodward Mark , Alderson Julie , Crowne Elizabeth C

17-beta-hydroxysteroid dehydrogenase (17-beta-HSD3) deficiency is an autosomal recessive 46XY disorder of sex development (DSD), which results in impaired gonadal androstenedione conversion to testosterone. The phenotype ranges from female to ambiguous genitalia, with wolffian-duct structures and testes. HCG stimulation tests assess testosterone biosynthesis, though biochemical results in confirmed 17-beta-HSD3 deficiency may overlap with gonadal dysgenesis making diagnosis ch...

11-year-old female, admitted in the emergency room due to postprandial hyperglycemia (350 mg/dL) in her father´s glucometer without ketosis or acidosis. She referred one-month evolution of mild symptoms, as polydipsia, polyuria, sporadic abdominal pain and nocturia.She was the first child of non-consanguineous parents, born full term at vaginal delivery with a birth weight of 3760g (90th percentile). Since 5-years-old her weight was betwe...

Whole Exome Sequencing in Patients with Primary Generalized Glucocorticoid Resistance Identifies a Novel TRIM28 Gene Mutation (p.R230X)

Sertedaki Amalia , Marinakis Nikos , Nicolaides Nicolas C. , Crousos George , Charmandari Evangelia

Introduction: Primary Generalized Glucocorticoid Resistance or Chrousos syndrome (CS) is a rare sporadic or familial disorder characterized by generalized, partial tissue insensitivity to glucocorticoids. Mutations of the NR3C1 gene, which encodes the human glucocorticoid receptor, have been identified in many but not all patients with CS.Objective: To identify novel genes related to CS in patients without NR3C1 gene mutations.<p cl...
