Ex vivo Culture of Human Fetal Gonads: Manipulation of Meiosis Regulation Affects Testis Development

Jorgensen Anne , Nielsen John E , Perlman Signe , Lundvall Lene , Juul Anders , Rajpert-De Meyts Ewa

Background: Alterations in the timing or expression level of players involved in sex determination and differentiation can cause disorders of sex development, gonadal dysgenesis and germ cell neoplasms later in life. The mitosis–meiosis switch is one of the first manifestations of female sex differentiation and we hypothesise that a conflict between meiosis-inhibiting (male pathway) and meiosis-inducing signals (female pathway) is one of the possible mechanisms for disrup...

The Association between rs4684677 T/A Polymorphism in Preproghrelin Gene And predisposition to Autoimmune Thyroid Diseases in Children*

Bosswski Artur , Moniuszko Anna , Wawrusiewicz-Kurylonek Natalia , Bossowska Anna , Jakubowska Ewa , Kretowski Adam

Background: Ghrelin and obestatin are two gastrointestinal peptides obtained by post-translational processing of a common precursor, preproghrelin. mRNA expression for preproghrelin was found in autoimmune thyroid diseases (AITDs) in previous studies. There are papers, where a role of preproghrelin polymorphism on various immunological diseases was determined, but nothing is known about its influence on the AITDs.Objective and hypotheses: The aim of our ...

Lipid Profile is Related to Androgen Level in Adolescent Girls with Type 1 Diabetes Mellitus

Zachurzok Agnieszka , Deja Grazyna , Gawlik Aneta , Drosdzol-Cop Agnieszka , Malecka-Tendera Ewa

Background: The mechanisms underlying dyslipidaemia in the context of polycystic ovary syndrome may include not only metabolic aberrations but also hormonal factors, in particular hyperandrogenaemia.Objective and hypotheses: The aim of the study was to establish whether dyslipidaemia and metabolic control disturbances are related to hyperandrogenaemia in adolescent girls with type 1 diabetes mellitus (T1DM).Method: We studied 54 gi...

Assessment of Omentin-1, Vaspin, and Visfatin Levels in Pediatric Patients with GH Deficiency

Sawicka Beata , Borysewicz-Sanczyk Hanna , Zasim Aneta , Jakubowska Ewa , Bossowski Artur

Introduction: GH deficiency (GHD) is a disease, in which the pituitary gland does not produce enough GH. GHD has a variety of different negative effects at different ages; e.g. it can result short stature and increased adiposity. Excessive intra-abdominal fat is associated with an increased risk of cardiovascular disease. In recent years new adipokines such as:omentin-1, vaspin, and visfatin have been described. Omentin-1 is decreased in obesity in contrast to increased vaspin...

Pituitary–Ovarian Axis in Patients with Isolated Premature Thelarche

Wikiera Beata , Nocon-Bohusz Julita , Basiak Aleksander , Bieniasz Jolanta , Glab Ewa , Noczynska Anna

Background: Isolated premature thelarche (IPT) is characterised by precocious breast development without any other signs of puberty.Objective and hypotheses: The aim of the study was to analyze hormonal activity of the pituitary – ovarian axis in girls with IPT.Method: 102 girls with IPT (Tanner stage 2–3), mean age 2±1.4 years (0.04–7 years), mean weight 12.3±4.3 kg, mean height 85.0±13.6 cm (45±...

Hypothalamic Hamartoma as a Cause of Central Precocious Puberty in 4.5-Year-Old Girl: Case Report

Jakubowska Ewa , Sawicka Beata , Borysewicz-Sanczyk Hanna , Zasim Aneta , Bossowski Artur

Background: Hamartoma is a benign, focal malformation, which is composed of tissue elements normally found at that site which are arranged chaotically within the mass. It may occur in many different parts of the body and often is undetected. Hypothalamic hamartoma, unlike most such growths, is symptomatic. It may cause gelastic seisures, visual problems, rage disorders and early onset of puberty.Objective and hypotheses: A 4.5-year-old girl was hospitali...

Re-Classification of Childhood Obesity by Steroid Metabolomic Disease Signature

Gawlik Aneta , Shmoish Michael , Hartmann Michaela , Malecka-Tendera Ewa , Wudy Stefan , Hochberg Ze'ev

Context: Analysis of steroids by gas chromatography – mass spectrometry (GC-MS) defines a subject’s ‘steroidal fingerprint’. Here, we clustered steroidal fingerprints to classify childhood obesity by ’steroid metabolomic signatures’.Methods: Urinary samples of 87 children (44 F) age 8.5–18.0 with obesity (BMI >97%) underwent solid phase extraction, enzymatic hydrolysis and derivatization. 31 steroids metabolites wer...

Analysis of Chosen Polymorphisms rs5742909 C/T – CTLA4, rs7522061 C/T – FCRL3, rs7138803 A/G – FAIM2 in Pathogenesis of Autoimmune Thyroid Diseases in Children

Jakubowska Ewa , Goscik Joanna , Wawrusiewicz-Kurylonek Natalia , Bossowska Anna , Kretowski Adam , Bossowski Artur

Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of cytotoxic T-lymphocyte-associated protein 4 (CTLA4) gene, Fc receptor-like 3 (FCRL3) gene, Fas apoptotic inhibitory molecule 2 (FAIM2) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association of polymorphi...

Backgrounds and objectives: Low bone mass density is an important problem in survivors of childhood cancers. The aim of this study is to determinate the influence of factors on bone mass density (BMD) and the prevalence of abnormal bone turnover.Materials and methods: The evaluation was performed in 67 patients (64.18% boys and 35.82% girls) at least 1 year after therapy of solid tumours, aged 4–27 years (median 12.67). The following parameters were...

Subclinical Hypothyroidism in Children and Adolescents – A 5-year Single-center Follow-up Study

Gawlik Aneta , Such Kamila , Dejner Aleksandra , Zachurzok Agnieszka , Antosz Aleksandra , Malecka-Tendera Ewa

Background: Most experts agree that subclinical hypothyroidism (SH) represents early, mild thyroid failure, however there are controversies about the evolution of SH over time.Objective and hypotheses: The aim of the study was to analyse the dynamics of thyroid dysfunction in children initially referred as patients with SH.Method: During the period January 2010 – January 2015, 258 unselected consecutive SH patients (140 girls)...
