Precocious/Early and Accelerated Puberty in a Boy with a Homozygous R192C Mutation in CYP19 (Aromatase) Gene

Costanzo Mariana , Guercio Gabriela , Garcia-Feyling Jose , Saraco Nora , Marino Roxana , Perez Garrido Natalia , Manuel Lazzati Juan , Maceiras Mercedes , Aurelio Rivarola Marco , Belgorosky Alicia

Background: Aromatase deficiency is a rare autosomal recessive disorder produced by CYP19 gene mutations. 46XX affected patients presented with ambiguous genitalia leading to early identification. Most 46XY affected patients presented normal external genitalia and the condition often remains undiagnosed until late puberty. Information on pubertal development in affected boys is scarce since to the present date only two patients, younger than 4 years of age, without lo...

Background: Childhood obesity is commonly associated with signs of endothelial dysfunction, characterized by impairment of insulin signaling and vascular NO availability. Recently both these features have been associated with endoplasmic reticulum (ER) stress, however the role of ER stress in the mechanism/s leading to vascular dysfunction in childhood obesity remains still to be established.Objective and Hypotheses: To evaluate ER stress and insulin-sti...

Background: Forkhead box P3 (Foxp3) is an important regulatory factor for the development and function of T regulatory cells (Tregs). Moreover it has been established that deficiency of the Foxp3 gene in Treg cells suppresses their regulatory function leading to the development of autoimmune diseases especially autoimmune thyroid diseases (AITDs).Objective and hypotheses: The aim of our study was to estimate the association of three polymorphism of FOXP3...

Gonadotropin Surge During the Early Postnatal Activation Period in 46,XX Testicular/Ovotesticular Disorder of Sex Development Patients

Costanzo Mariana , Guercio Gabriela , Marino Roxana , Ramirez Pablo , Garrido Natalia Perez , Vaiani Elisa , Berensztein Esperanza , Lazzati Juan Manuel , Maceiras Mercedes , Rivarola Marco A , Belgorosky Alicia

Background: During the 1st months of postnatal life serum luteinizing hormone (LH) levels in girls are lower than in boys. The mechanism of this sex difference is not known. It has been proposed that foetal or perinatal androgenic steroids have an effect on the control of LH secretion.Objective and hypotheses: To study the possible influence of high levels of androgens on serum gonadotropins during the 1st months of life in a cohort of nine 46,XX testicu...

Background: According to the World Health Organization, the social determinants of health, the conditions in which people are born, grow, live and work – significantly influences on health. The CAF Foundation, the Endocrinology Scientific Center and the Institute for Family Health under the Alfa-Endo Program studied prevalence of some social determinants in families of children with type 1 diabetes mellitus.Objective and hypotheses: Investigate soci...

Two Novel Mutations in GLI2 Gene in Two Unrelated Argentinean Prepuberal Patients, One with Isolated Growth Hormone Deficiency, and Another with Multiple Pituitary Hormone Deficiency, Both with Developmental Defects in Posterior Pituitary Gland

Marino Roxana , Juanes Matias , Ramirez Pablo , Garrido Natalia Perez , Ciaccio Marta , Palma Isabel Di , Maceiras Mercedes , Lazzati Juan Manuel , Rivarola Marco Aurelio , Belgorosky Alicia

Background: Congenital growth hormone deficiency may be isolated (IGHD) or multiple pituitary hormone deficiency (MPHD). The Sonic Hedgehog signalling (SHH) pathway has an important role in the pituitary development and growth, acting early in ventral forebrain. The SHH signalling mediates its effects through three zinc fingers proteins (Gli1, Gli2 and Gli3), which lead to activation or repression of target genes. Several heterozygous GLI2 mutations have been reported in patie...

Evaluation of genomic copy number variations in the etiology of syndromic patients with diferences of sex development (DSD)

Antonio Diniz Faria Junior Jose , R. Moraes Daniela , L. Batista Rafael , Gomes Lisboa Natalia , D. Kulikowski Leslie , Y Nishi Miriam , B Mendonca Berenice , Domenice Sorahia ,

Differences of sex development (DSD) occurs when the development of chromosomal sex, gonadal or internal/external genitalia is atypical. It has an incidence of 1: 1000-4500 live born children. New chromosomal array technologies (SNP-array) can analyze the genome of the individual providing information of copy number variation (CNV) of specific chromosomal regions helping to identified pathogenic variants that could explain the etiology of the DSD. This study aims to analyze th...

Hormone-Secreting Pituitary Adenomas in Children and Adolescents

Akulevich Natallia , Kuzmenkova Elena , Zhuravlev Vladimir , Solntsava Anzhalika

Background: Hormone-secreting pituitary adenomas in children and adolescents are rare.Methods: We report clinical course, management and outcome of 6 cases diagnoses in 2013-2019.Results: Patients (3M, 3F), aged 9,5 – 16,5 years at referral. In them, 3 ACTH-secreting adenomas (ACTHA) and 3 prolactinomas (PROLA) were recognized. The family history for endocrine tumors was negat...

The P30L Mutation in the CYP21A2 Gene in a Girl with Congenital Adrenal Hyperplasia with Hidden Salt Loosing and Central Precocious Puberty

Akulevich Natallia , Boiko Julia , Mirabelli Silvestro , DeLuca Filippo , Wasniewska Malgorzata

In CAH due to 21-OH deficiency, phenotype-genotype correlation is known. However, the same genetic events may cause different clinical forms of the disease. A case of CAH associated with the P30L in the CYP21A2 gene in presented. The Caucasian girl was born normally and growing healthy till the age of 3.y., when her mother noticed pubic hair growth; at the age of 4 she had acne and an increasing sweating. At 6 y. of age, she was brought to paediatric endocrinologist f...

Unusual Clinical Manifestations in Turner Syndrome

Akulevich Natallia , Makarava Yulia , Ershova Larissa , Kunavitch Irina

Turner syndrome (TS) is characterized by partly or completely missing of an X chromosome and variability of clinical signs. We present tree Caucasian mosaic TS girls with unusual clinical course and discuss some literature.Case 1: A girl referred first to paediatric endocrinologist at the age of 8.5 y. for metabolic problems (an excessive weight gain, acanthosis nigricans, impaired glucose tolerance, hyperinsulinemia). The height was not a concern (Media...
