Insulin-like growth factor 1 (IGF1) is a multifunctional peptide that is involved in a wide range of physiological and patho-physiological processes in many animal species, ranging from somatic growth in children to metabolism, and tissue regeneration and repair in adults. The IGF1 gene is under multifactorial regulation in the few species in which it has been studied, with major control being exerted by growth hormone (GH) through a gene expression pathway involving inducible binding of the STAT5b transcription factor to dispersed enhancer elements...

Context: Daily injections are required for growth hormone replacement therapy, which may cause low compliance as a result of inconvenience and distress in patients. Objective: CTP-modified human growth hormone (MOD-4023) is developed for once-a-week dosing regimen in GH-deficient (GHD) adults and children. The present trial was a safety and dose-finding study for weekly MOD-4023 in GHD children. Design: a multi-center, open-label, randomized, controlled Phase 2 study in children with GHD, evaluating the safety, tolerability, PK/PD and efficacy of 3 different weekly MOD-4023 doses, compared to daily r-hGH...

BACKGROUND: The majority of children who present for evaluation of tall stature fall under the diagnosis of constitutional tall stature (CTS). METHODS: To investigate mechanisms of tall stature, we evaluated serum IGF-I values and the expression of the GHR gene in the peripheral blood cells of 46 subjects with normal height, 38 with tall stature and 30 healthy children with short stature. RESULTS: Our results showed significantly lower IGF-I levels in children with short stature (-0...

BACKGROUND: Gadolinium-based contrast agents (GBCAs) have been used for magnetic resonance (MR) imaging over the last three decades. Recent reports demonstrated gadolinium retention in patients' brains following intravenous administration. Since gadolinium is a highly toxic heavy metal, there is a potential for adverse effects from prolonged retention or deposition, particularly in children. For this reason, the Society (SPR) for Pediatric Radiology Quality and Safety committee conducted a survey to evaluate the current status of GBCAs usage among pediatric radiologists...

BACKGROUND: Iodine is an essential nutrient required for the biosynthesis of thyroid hormones, which are responsible for regulating growth, development and metabolism. Iodine requirements increase substantially during pregnancy and breastfeeding. If requirements are not met during these periods, the production of thyroid hormones may decrease and be inadequate for maternal, fetal and infant needs. The provision of iodine supplements may help meet the increased iodine needs during pregnancy and the postpartum period and prevent or correct iodine deficiency and its consequences...

The advancement of "human growth hormone (hGH)-for-height" - increasing height attainment in children short for reasons other than GH deficiency - arose from intuitive, deep-seated assumptions about the disability of short stature, its improvement with hGH-mediated height gain, and the safety of escalating dosages of hGH in healthy children. Evidence challenging these assumptions now strengthens criticism of hGH-for-height as cosmetic endocrinology. To counter this characterization, collective acceptance of guidelines is needed that advise nontreatment of the vast majority of short children, support strategies that minimize treatment duration and dosage, and restrain enhancement of normal adult stature...

PURPOSE: Research demonstrates that children and adolescents with growth hormone deficiency (GHD) are impacted in multiple ways beyond their short stature; however, there are no disease-specific measures to assess these impacts. The purpose of this study was to examine the burden of GHD on children and adolescents, and to conduct concept elicitation to develop a model of the impact of GHD to support a disease-specific outcome measure. METHODS: Four focus groups and 52 telephone interviews were conducted with children with GHD and parents/guardians of children with GHD to understand the experience and impacts from the child's perspective, reported by children or parent-observers about the impact on the child...

BACKGROUND: Knowledge concerning energy metabolism in Turner syndrome (TS) is lacking. We compared the resting energy expenditure per fat-free mass (REE/FFM) in TS with other girls with short stature treated with growth hormone (GH) and age-related controls. METHODS: We measured prospectively REE by spirometry under fasting conditions in the morning in 85 short prepubertal girls at the start of GH treatment. Diagnoses were TS (n=20), GH deficiency (GHD) (n=38) and small for gestational age (SGA) short stature (n=27)...

Organochlorine chemicals and lead are environmental exposures that have endocrine disrupting properties (EDCs) which interfere with many aspects of hormone action. Childhood and adolescence are windows of susceptibility for adverse health effects of EDCs. Our ongoing study, the Russian Children's Study (RCS), is one of the few longitudinal studies investigating the impact of EDCs on growth and puberty in boys. It is conducted in the historically contaminated city of Chapaevsk, in the Samara region. The study focuses on evaluating the associations of persistent organochlorine chemicals and lead with growth and pubertal timing...

Childhood obesity is a major public health problem that has grown to epidemic proportions throughout the world. Obesity is influenced by genetic and environmental factors. The nutritional status plays an important role in growth and body weight regulation. Excess adiposity during childhood can affect the process of growth and puberty. Obese children are frequently tall for their age, with accelerated epiphyseal growth plate maturation despite low growth hormone levels. Several regulatory hormones may affect the process of linear growth in the constellation of obesity, as high levels of insulin and leptin are observed in obese children...

Synthetic glucocorticoids (GCs) are widely used in the variety of dosages for treatment of premature infants with chronic lung disease, respiratory distress syndrome, allergies, asthma, and other inflammatory and autoimmune conditions. Yet, adverse effects such as glucocorticoid-induced osteoporosis and growth retardation are recognized. Conversely, 2-oxoglutarate (2-Ox), a precursor of glutamine, glutamate, and collagen amino acids, exerts protective effects on bone development. Our aim was to elucidate the effect of dietary administered 2-Ox on bone loss caused by neonatal treatment with clinically relevant maximal therapeutic dexamethasone (Dex) dose...

BACKGROUND: Small size at birth and rapid growth in early life are associated with increased risk of cardiovascular disease in later life. Short children born small for gestational age (SGA) are treated with growth hormone (GH), inducing catch-up in length. Leukocyte telomere length (LTL) is a marker of biological age and shorter LTL is associated with increased risk of cardiovascular disease. OBJECTIVES: To investigate whether LTL is influenced by birth size, childhood growth and long-term GH treatment...

Back ground: Thyroid hormone (T3) is essential for normal development of children enabling brain development and somatic growth. However, certain individuals are genetically predisposed with insufficient or no thyroid hormones. Such a condition is termed congenital hypothyroidism (CH). OBJECTIVE: In the present review, a brief back ground about congenital hypothyroidism, factors associated with CH leading to thyroid dysgenesis and thyroid dyshormonogenesis is elaborated. Additionally, the guidelines for available treatment options, management and follow-up required for patients diagnosed with CH are discussed...

Adrenocortical tumours are rare in children. Virilisation caused by overproduction of adrenal androgens is the most common presentation. The testes of pre-pubertal boys with this tumour are usually small or of pre-pubertal size. A 4.8-year-old boy with an adrenocortical tumour and symmetrical pubertal-sized testes is reported. The serum testosterone level was 204 nmol/L (<0.7), dehydro-epiandrosterone-sulphate 56.7 μmol/L (<1.5) and luteinising and follicle-stimulating hormones were at suppressed levels...

The regulation of linear growth by nutritional and inflammatory influences is examined in terms of growth-plate endochondral ossification, in order to better understand stunted growth in children. Linear growth is controlled by complex genetic, physiological, and nutrient-sensitive endocrine/paracrine/autocrine mediated molecular signalling mechanisms, possibly including sleep adequacy through its influence on growth hormone secretion. Inflammation, which accompanies most infections and environmental enteric dysfunction, inhibits endochondral ossification through the action of mediators including proinflammatory cytokines, the activin A-follistatin system, glucocorticoids and fibroblast growth factor 21 (FGF21)...
