Background: Deficiency of one or more pituitary hormones, often with growth hormone (GH) deficiency, is defined as multiple pituitary hormone deficiencies (MPHD) or congenital hypopituitarism (CH). CH cases are mostly sporadic and have a prevalence of 1/3000-4000 live births. There are many known and yet unknown molecular pathways explaining the complex structure and functions of the pituitary gland. Many different gross and small sequence variants in the gene...

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood. Type 1 diabetes (T1DM) is the most common metabolic disease in children. The treatment of T1DM requires high executive functions and requires very intensive treatment that could be an obstacle for patients with ADHD. Dual diagnosis of T1DM and ADHD might affect treatment, control and complications of T1DM. In order to prevent long-term complica...

Objectives: Forkhead box A2 (Foxa2) is a transcription factor that plays a key role in foregut, pancreatic and central nervous system development. Here, we describe a 7 years old boy whose phenotype is consistent with FOXA2 defect.Case: A 3 months old boy was referred for recurrent hypoglycemic events. He was born to unrelated parents at term with a birth weight of 3690 gr. At 6 hours of life he had severe hypoglycemia (...

Background: Aromatase excess syndrome (AEXS) (OMIM 139300) is a rare condition characterized with gynecomastia in boys and macromastia in girls. Estrogen excess in boys can lead to prepubertal and pubertal gynecomastia, bone age progression and short adult stature. While most of girls are usually asymptomatic, there are few reported female patients with excessive breast growth, early puberty, menstrual irregularities, and short adult stature. Male and female children with AEXS...

Background: Ectopic posterior pituitary gland (EPP) is characterized by an abnormal pituitary stalk and hypoplasia of the anterior hypophysis. The genetic mechanisms involved in the development of EPP remain uncertain.Objective and hypotheses: The aim of this study is to determine whether mutations in the three genes, PROP-1, LHX2, and POU1F1, are associated with the risk for and the characteristics of EPP.Method: In the Endocrinol...

Zinc Transporter 8 (ZnT8) as a New Autoantigen in Thyroid Tissue – Preliminary Data

Bossowski Artur , Niklinska Wieslawa , Gasowska Marta , Polnik Dariusz , Szalecki Mieczyslaw , Miklosz Agnieszka , Chabowski Adrian , Reszec Joanna

Zinc (Zn) is a crucial trace mineral that regulates the expression and activation of biological molecules such as transcription factors, enzymes, adapters, channels, and growth factors, along with their receptors. Bioinformatics analysis of the human genome discloses that Zn may bind ~ 10% of all of the proteins found in the human organism. This remarkable finding highlights the physiological significance of Zn in molecules involved in cellular processes and thereby i...

Identification of Zinc Transporter ZnT8 in Thyroid Tissues from Children and Adolescents with Thyroid Nodular Hyperplasia

Bossowski Artur , Niklinska Wieslawa , Gasowska Marta , Goralczyk Aleksandra , Polnik Dariusz , Reszec Joanna

Background: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. It has been demonstrated that the ZnT family plays an important role in the synthesis and secretion of different hormones. Furthermore, ZnT8Ab (zinc transporter-8 autoantibodies) together with GADAb (glutamic acid decarboxylase antibodies), IAA (insulin autoantibodies) and IA-2Ab (islet antigen-2 antibodies) are markers of auto...

Cushing’s Syndrome due to Ectopic ACTH Secretion by a Germline Tumour in the Cross-tail Area in a 7 Month Old Female Infant

Bossowski Artur , Kuzmicz Marta , Kitszel Anna , Polnik Dariusz , Savage Martin , Krawczuk-Rybak Maryna

Background: Ectopic ACTH syndrome is very rarely seen in infancy, usually occurring in older children.Case presentation: A female infant was born by Caesarean section (BW 4280 g) with congenital anal atresia and a large tumour surrounding the cross-tail region. CT imaging identified a heterogeneous pelvic mass (76×49×38 mm) below the sacrum. On day 1 of life, a sigmoid colostomy was established and at age 1 week, part of the tumour with the coc...

Inflammation associated to body composition in European prepubertal children: Results from the IDEFICS study

Argente Pilar , Esther Gonzalez , Intemann Timm , Moreno Luis , Molnar Denes , Kaprio Jaakko , Russo Paola ,

Background: Obesity is characterised by excessive fat accumulation coursing with a chronic mild inflammatory state, with adipose tissue (AT) being the main site of increased systemic cytokine production. Increased adiposity early in life is the main risk factor for cardiometabolic disorders later in life, with the abnormal accumulation of lipids in AT leading to the production of pro-inflammatory cytokines. Inflammatory process that involves metabolic and card...
