Growth hormone and insulin-like growth factor-1 (IGF-1) play a crucial role in the regulation of bone turnover. Adequate vitamin D status supports proper bone remodeling, leading to normal longitudinal bone growth and normal peak bone mass. The aim of this study was to evaluate the association between serum 25-hydroxyvitamin D [25(OH)D] and carboxy-terminal cross-linked telopeptide of type I collagen (ICTP) in children and adolescents with growth hormone deficiency at baseline and during recombinant human growth hormone (rhGH) replacement therapy...

BACKGROUND AND OBJECTIVE: The sequence of prenatal growth restraint and postnatal catch-up growth may lead to hepato-visceral adiposity, insulin resistance and low-grade inflammation before the onset of puberty. In prepubertal children born appropriate for gestational age (AGA) or small for gestational age (SGA), we assessed potential relationships between the aforementioned sequence and liver volume. SUBJECTS/METHODS: The study population consisted of 86 children (41 AGA and 45 SGA with catch-up growth; age (mean±s...

BACKGROUND: Thalassaemia is a recessively-inherited blood disorder that leads to anaemia of varying severity. In those affected by the more severe forms, regular blood transfusions are required which may lead to iron overload. Accumulated iron from blood transfusions may be deposited in vital organs including the heart, liver and endocrine organs such as the pituitary glands which can affect growth hormone production. Growth hormone deficiency is one of the factors that can lead to short stature, a common complication in people with thalassaemia...

OBJECTIVE: Genetic alterations in GH1 and GHRHR genes are known to cause isolated growth hormone deficiency (IGHD). Of these, GHRHR codon 72 mutation has been reported to be highly prevalent in the Indian subcontinent, but among Sri Lankans its prevalence was low compared to reports from neighboring countries. The present study was therefore carried out to identify genetic alterations in the GH1 gene and rest of the GHRHR gene in a cohort of Sri Lankan IGHD patients who tested negative for GHRHR codon 72 mutation...

Pharmacogenetics aims to maximize the beneficial effects of a medical therapy by identifying genetic finger prints from responders and non-responders and, thereby, improving safety and efficacy profile of the drug. Most subjects who are deficient in growth hormone (GHD) are candidates for recombinant human GH (rhGH) therapy. To date, it is well established that even after adjustments for several clinical variables, such as age, gender, body composition and the age at onset of the GHD, response to rhGH treatment is highly variable among individuals, part of which is believed to be due to genetic factors within the GH system...

BACKGROUND: α-Klotho is a transmembrane protein that can be cleaved and act as a circulating hormone (s-klotho). s-Klotho serum levels seem to reflect growth hormone (GH) secretory status. We investigated the role of s-klotho as a reliable marker of GH secretion in short children and the factors influencing its secretion. METHODS: We enrolled 40 short Egyptian children (20 GH deficiency [GHD] and 20 idiopathic short stature [ISS]). They underwent a pegvisomant-primed insulin tolerance test (ITT) and were accordingly reclassified as 16 GHD and 24 ISS...

Growth hormone deficiency results in growth retardation in children and the GH deficiency syndrome in adults and they need to receive recombinant-GH in order to rectify the GH deficiency symptoms. Mammalian cells have become the favorite system for production of recombinant proteins for clinical application compared to prokaryotic systems because of their capability for appropriate protein folding, assembly, post-translational modification and proper signal. However, production level in mammalian cells is generally low compared to prokaryotic hosts...

Silver-Russell syndrome (SRS) is a very rare genetic disorder characterized by intrauterine growth retardation, short stature, and typical craniofacial abnormalities including micrognathia. While growth hormone (GH) therapy in children with SRS significantly improves somatic growth, functional orthopedic treatment can also be effective in adolescents with mandibular deficiency. We report the effects of Phase 1 functional orthopedic treatment of a twin-block appliance in conjunction with GH administration in a 9-year-old boy with GH deficiency and SRS, and the result of the subsequent Phase 2 orthodontic treatment...

Bone growth and remodeling is inhibited by denervation in adults and children, resulting in alterations of linear growth and bone mass and increased risk for osteoporosis and pathologic fractures. Transforming growth factor beta (TGF-β) isoforms are a key group of growth factors that enhance bone formation. To explore the relation between denervation-induced reduction of bone formation and TGF-β gene expression, we measured mRNA levels of TGF-β in denervation mouse bone and found decreased mRNA levels of TGF-β1, TGF-β2 and TGF-β3...

Thyroid hormones are essential for skeletal development and are important regulators of bone maintenance in adults. Childhood hypothyroidism causes delayed skeletal development, retarded linear growth and impaired bone mineral accrual. Epiphyseal dysgenesis is evidenced by classic features of stippled epiphyses on X-ray. In severe cases, post-natal growth arrest results in a complex skeletal dysplasia. Thyroid hormone replacement stimulates catch-up growth and bone maturation, but recovery may be incomplete dependent on the duration and severity of hypothyroidism prior to treatment...
