Expression of ZnT8 Transporter in Thyroid Tissues from Patients with Immune and Non-Immune Thyroid Diseases

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

Introduction: Zinc homeostasis is regulated by ZnT and Zip zinc transporters. Zinc transporter 8 (ZnT8) is localized in insulin containing secretory granule membrane and transports zinc from the cytosol into the vesicles. ZnT8 was identified on peripheral lymphocytes, in subcutaneous adipose tissue, in a pancreatic β-cells and extra-pancreatic endocrine glands including pituitary, adrenal and thyroid. Autoantibodies to the ZnT8 are detected in the majority of type 1 diabe...

Significance of IGF-I Generation Test in Diagnosing Primary and Non-Primary IGF-I Deficiency – Clinical Considerations

Smyczynska Joanna , Smyczynska Urszula , Stawerska Renata , Lewinski Andrzej , Hilczer Maciej

Background: The diagnosis of severe primary IGF-I deficiency (IGFD) in children with normal growth hormone (GH) peak in stimulation tests (stimGH) should be confirmed by IGF-I increase <15.0 ng/ml during generation test (IGF-GT), however the significance of IGF-GT has been questioned by some researchers.Objective and hypotheses: Evaluation of the significance of IGF-GT in children with normal stim GH and IGFD, with respect to efficacy of growth-promo...

What Should be the Diagnosis and Management of Short Children with IGF1 Deficiency, Responding to GH Administration Despite Normal GH Secretion?

Smyczynska Joanna , Stawerska Renata , Lewinski Andrzej , Hilczer Maciej

Background: GH deficiency (GHD) is currently defined as secondary IGF1 deficiency (IGFD). In the patients with normal GH secretion and IGFD, significant increase of IGF1 during generation test excludes primary IGFD, however is not an approved indication for GH therapy.Objective and hypotheses: The aim of the study was to assess GH therapy effectiveness in children with IGFD, responding to short-term GH administration despite normal GH peak after falling ...

Effectiveness of GH Therapy in Children with Short Stature and Decreased GH Peak in Stimulating Tests is Independent from GH Secretion After Falling Asleep

Hilczer Maciej , Smyczynska Joanna , Stawerska Renata , Lewinski Andrzej

Background: GH deficiency (GHD) is routinely diagnosed on the basis of decreased GH peak in two stimulating tests (GHST). In Poland, few years ago, an assessment of nocturnal GH secretion after falling asleep (noctGH) has been introduced as a screening test in diagnosing GHD.Objective and hypotheses: The aim of the study was to assess GH therapy effectiveness in children with decreased GHST with respect to noctGH.Method: Retrospect...

Linear Regression Model of Final Height Prediction Based on Pre-Treatment Data in Children with GH Deficiency Treated with GH

Hilczer Maciej , Smyczynska Joanna , Smyczynska Urszula , Stawerska Renata , Lewinski Andrzej

Background: Prediction of GH therapy effectiveness in children with short stature is an important issue in paediatric endocrinology.Objective and hypotheses: The aim of the study was to create a linear regression model of GH therapy effectiveness, based on the data available before treatment.Method: Retrospective analysis comprised the data of 150 short children (101 boys), diagnosed with isolated GH deficiency, who were treated wi...

The effect of growth hormone therapy on body composition in girls with Turner syndrome – a 10-year follow-up.

Błaszczyk Ewa , Shulhai Anna-Mariia , Gieburowska Joanna , Gawlik Aneta

Background: Obesity and a thicker layer of subcutaneous adipose tissue are more common in Turner syndrome (TS), however, it is assumed that growth hormone (GH) treatment has beneficial effect on their body composition (BC). Objective: To investigate the effect of GH therapy on BC and its relation with metabolic syndrome components in girls with TS during a 10 year-follow-up.Patients and Methods: 21 girls with TS were des...

Changes in carbohydrate and lipid metabolism during 10-year follow-up of patients with Turner syndrome treated with growth hormone.

Błaszczyk Ewa , Shulhai Anna-Mariia , Gieburowska Joanna , Gawlik Aneta

Background: Disorders in carbohydrate and lipid metabolism are more common in girls with Turner syndrome (TS) than in general population. Metabolic disorders have been identified as risk factors for the development of cardiovascular diseases. Additionally, TS patients are usually treated many years with growth hormone (GH) that affects the parameters of carbohydrate-lipid metabolism. Therefore cardiovascular risk factors should be monitored in TS girls.<p ...

Effect of iodinated contrast on the thyroid function in young children

Wing Kei Ng Carol , Kan Elaine , Ling Joanna Tung Yuet

Background: Hypothyroidism is a well-known treatable cause of global developmental delay in developing children. In recent years contrast imaging studies are much more commonly employed as diagnostic means in the treatment of various pediatric conditions. In 2022, the FDA issued a warning recommending thyroid function monitoring in babies and young children who receive injections of iodine-containing contrast media(ICM) for medical imaging. They recommend the ...

Incidence of false positive results of growth hormone stimulation tests in children with short stature – from theoretical background to clinical approach

Smyczyńska Joanna , Hilczer Maciej , Lewiński Andrzej , Stawerska Renata

Diagnosis of growth hormone (GH) deficiency (GHD) requires direct confirmation by decreased GH peak in stimulation tests (GHST), with measurement of IGF-1 proposed as laboratory screening [Wit et al. 2020]. Taking into account the low incidence of GHD, theoretical incidence of false positive (FP) results of GHST is relatively high [Bright et al. 2022]. Performing two (or more) GHST in each patient decreases the FP rate. Retrospective analysis included data of...

A Comparison of Insulin Resistance Indices: HOMA and Belfiore in 6-8-Year-Old, Properly Growing Children, Born Small for Gestational Age

Stawerska Renata , Lupinska Anna , Szalapska Malgorzata , Kolasa-Kicinska Marzena , Smyczynska Joanna , Hilczer Maciej , Lewinski Andrzej

Introduction: It is well known that low birth weight in children (born small for gestational age, SGA) predisposes them to the occurrence of obesity, insulin resistance (IR) and lipid disorders, observed even through the whole first decade of life. Thus, early diagnostics and prevention are very important. The HOMA index is used to assess insulin resistance (IRIHOMA). However, in some cases, high, prolonged postprandial insulin secretion is observed...
