Background: The TRH receptor (TRHR) is a G-protein coupled receptor activated by hypothalamic TRH. In thyrotropes, TRH-TRHR signalling controls synthesis, secretion and bioactivity of TSH. Human TRHR defects are extremely rare, and only three cases are known with central hypothyroidism and short stature as variable presenting feature.Objective and hypotheses: Phenotypical characterization of a family with suspected central hypothyroidism and inv...

Background: Sclerostin is secreted by the osteocyte and inhibits bone formation by osteoblasts and is thus a negative regulator of bone formation. In adults, sclerostin levels increase after weight loss, which may be prevented by exercise training. The effect of weight loss on sclerostin in children is unknown.Objective and hypotheses: To compare sclerostin levels in children before and after a 10 weeks stay at a weight loss camp (WLC).<p class="abst...

Background: Type 1 diabetes mellitus (T1DM) is an important risk factor for cardiovascular events. Endothelial dysfunction and carotid intima-media thickness (CIMT) lead to increased cardiovascular complications. Adhesion molecules such as vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) are markers of early atherosclerosis and play a significant role in developing atherosclerosis. The general aim of the present study was to investigate...

Objective and hypotheses: The aim of the study is comparison of the occurrence of islet autoantibodies in healthy siblings of children with T1DM to healthy children from non-diabetic families.Method: Determination of anti-decarboxylase of the glutamic acid antibodies (anti GAD-Ab), anti-protein tyrosine phosphatase (anti IA2), and antibodies against zinc transporter eight (anti ZnT8) in 75 children with T1DM, their siblings – 105, and 77 healthy chi...

Background: Obesity is a major public health problem and its rate is increasing worldwide. Obesity accompanies perturbations in metabolism, conferring substantial excess risk for insulin resistance and Type 2 diabetes. Various genetic and epigenetic factors contribute to the development of obesity. MicroRNAs (miRNAs) are short noncoding RNAs involved in posttranscriptional regulation of gene expression and influence many cellular functions including glucose and lipid metabolis...

Background: TransCon hGH, is a once-weekly prodrug releasing unmodified hGH, for the treatment of Growth Hormone Deficiency (GHD) in children and adults. To date, TransCon hGH has demonstrated comparable efficacy, safety and anti-hGH immunogenic profile to daily hGH, with no occurrence of neutralizing antibodies.Objective and hypotheses: Protein-based therapies may be associated with generation of drug-specific antibodies, which may impact efficacy, part...

Background: α-klotho is a transmembrane protein which can be cleaved and act as a circulating hormone. Since low α-klotho levels were found in organic GH deficiency (GHD) and high levels in acromegaly, an interaction between α-klotho, GH and linear growth has been suggested.Objective and hypotheses: We investigated the role of α-klotho protein as a reliable marker of GH secretion in short children and the factors influencing its secre...

Objective and hypotheses: The purpose was to get the basic data of optimum serum concentration of estrogen in maximizing pubertal growth spurt, and decreasing the acceleration of epiphyseal closure of long bones.Method: i) Fifteen female SD rats (13-week aged; post pubertal growth spurt) were randomly divided into three groups. After 1 week, the group 1 were injected subcutaneously with sesame oil, as a control, group 2 were with 10 μg/kg per week o...

Background: Arginine HCl infusion is commonly used in the diagnostic workup of GH deficiency. There is a paucity of data whether obesity and/or short stature modulate arginine plasma concentration and associated arginine-stimulated GH secretion following a weight-based arginine infusion protocol.Objective and hypotheses: To study whether auxiological parameters modulate the arginine plasma concentration profile and associated GH secretion in children und...

Background: Hypothalamic obesity (HyOb) is a rare form of treatment-resistant morbid obesity associated with congenital or acquired hypothalamic damage. Its pathophysiology has been attributed to hyperphagia and hyperinsulinaemia. The wider roles of oxytocin (OXT) in regulating appetite and weight have recently emerged in animal and human studies, but there is no human evidence that hypo-oxytocinaemia contributes to weight gain.Hypothesis: Hypo-oxytocina...
