Purpose: Adherence to recombinant human growth hormone (r-hGH) is critical to growth and other outcomes in patients with growth disorders, but the requirement for daily injections means that ease of use is an important factor. This study assessed the perceived ease of use and functionality of the prototype of a reusable pen injector (pen device) for r-hGH that incorporates several advanced features. Participants and methods: Semi-structured 60-minute qualitative interviews were conducted in 5 countries with 57 health care professionals (HCPs) and 30 patients with GH deficiency/caregivers administering r-hGH to patients, including children...

Individuals with inflammatory bowel disease (IBD) often present with poor bone health. The development of targeted therapies for this bone loss requires a fuller understanding of the underlying cellular mechanisms. Although bone loss in IBD is multifactorial, the altered sensitivity and secretion of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) in IBD is understood to be a critical contributing mechanism. The expression of suppressor of cytokine signaling 2 (SOCS2), a well-established negative regulator of GH signaling, is stimulated by proinflammatory cytokines...

A typical clinical manifestation of growth hormone deficiency (GHD) is a short stature resulting from delayed growth, but GHD affects bone health, cardiovascular function and metabolic profile and therefore quality of life. Although early GH treatment during childhood has been shown to improve outcomes, no single biochemical parameter is currently available for the accurate diagnosis of GHD in children. There is hence a need for non-invasive biomarkers. In this study, the relative abundance of serum proteins from GHD children and healthy controls was measured by next-generation proteomics SWATH-MS technology...

Recombinant human insulin-like growth factor-1 (rhIGF-1) treatment studies of growth failure in absence of growth hormone (GH) signaling (GH insensitivity -GHI, Laron syndrome -LS, GH Receptor deficiency -GHRD) have taken place in many locations around the globe. Results from these trials are comparable, and slight differences reported can be attributed to specific circumstances at different research sites. rhIGF-I treatment studies of GHI in Ecuador included various trials performed on children belonging to the largest and only homogeneous cohort of subjects with this condition in the world...

OBJECTIVE: Silver-Russell Syndrome is both clinically and genetically a heterogeneous syndrome. Among the most important dysmorphic features of this condition are: a triangular shaped face with a small mandible, a prominent frontal eminence, a thin vermilion border with downward-pointing lip corners, clino- and brachydactyly of the 5th fingers as well as body asymmetry. The most well-known genetic mutations in this syndrome are: the 11p15 epimutation (20-60% patients) and the maternal uniparental chromosome 7 disomy present in 7% to 15% of patients...

Background and Objectives: Short stature (SS) is a common pediatric problem and it might be the first sign of underlying illness. Studies documenting the burden and etiological profile of SS are scarce from India and are mostly limited to data obtained from referral centers. Due to the lack of large-scale, community-based studies utilizing a standard protocol, the present study aimed to assess the prevalence and etiological profile of SS in school children of a South Indian district. Materials and Methods: In this cross-sectional study, children aged 4-16 years from 23 schools in Madurai district, Tamil Nadu, underwent anthropometric measurements and height was plotted in Khadilkar et al...

Growth hormone (GH) was first isolated from cadaver pituitary glands, requiring laborious and expensive collection of glands, followed by extraction and purification of the hormone. This limited supply restricted its use to children with severe GH deficiency who were treated with low dosages and suboptimal schedules. The development of recombinant DNA-derived GH, allowed the production of virtually unlimited amounts of GH, leading to the approval for therapy for a large number of childhood conditions characterized by non-GH deficient short stature...

OBJECTIVE: Provocative stimulation tests for growth hormone (GH) assessment have poor reproducibility and can often elicit false positive results in normal children. The aim of our study was to confirm the capability of pegvisomant as an enhancer of GH secretion in unmasking false-positive results in short children (height <-2.0 standard deviation score, SDS) undergoing GH testing. DESIGN: A prospective study was conducted between March and August 2016. Twenty short children (10 males and 10 females), aged 4...

OBJECTIVE: Data about the impact of growth hormone treatment (GHT) on insulin sensitivity in children are quite controversial, due to the different surrogate indices that have been used. DESIGN: We evaluated insulin sensitivity through the euglycemic hyperinsulinemic clamp, considered the gold standard technique, in 23 children affected by growth hormone deficiency (GHD) at baseline and after 12months of GHT and in 12 controls with short stature at baseline, and we compared the clamp-derived index (M-value) with the most commonly used surrogate index of insulin sensitivity, as ISI Matsuda, and with circulating plasma markers of insulin sensitivity, as adiponectin and resistin levels...

Numerous studies have examined the association between pharmacogenetic effects and the response to inhaled corticosteroids (ICS) in patients with asthma. In fact, several single nucleotide polymorphisms of a number of candidate genes have been identified that might influence the clinical response to ICS in children with asthma. Their direct or indirect effects depend on their role in the inflammatory process in asthma or the anti-inflammatory action of corticosteroids, respectively. Among the genes identified, variants in T-box 21 ( TBX21) and Fc fragment of IgE receptor II ( FCER2) contribute indirectly to the variability in the response to ICS by altering the inflammatory mechanisms in asthma, while other genes such as corticotropin releasing hormone receptor 1 ( CRHR1), nuclear receptor subfamily 3 group C member 1 ( NR3C1), stress induced phosphoprotein 1 ( STIP1), dual specificity phosphatase 1 (DUSP1), glucocorticoid induced 1 (GLCCI1), histone deacetylase 1 (HDAC), ORMDL sphingolipid biosynthesis regulator 3 (ORMDL3), and vascular endothelial growth factors (VEGF) directly affect this variability through the anti-inflammatory mechanisms of ICS...

The precise mechanisms relating type 1 diabetes (T1D) and poor glycemic control to the axis of growth hormone (GH), insulin like growth factor- I (IGF-I), and IGF binding protein-3 (IGFBP-3) remain to be definitively determined. GH resistance with low IGF-I as is frequently seen in patients with T1D is often related to portal hypoinsulization, and lack of upregulation of GH receptors. There are conflicting reports of the effect of a dysregulated GH/IGF-I axis on height in children and adolescents with T1D, as well as on chronic complications...

Mathematical models have been applied in prediction of growth hormone treatment effectiveness in children since the end of 1990s. Usually they were multiple linear regression models, however there are also examples derived by empirical non-linear methods. Proposed solution consists in application of machine learning technique - artificial neural networks - to analyse this problem. This new methodology, contrary to previous ones, allows detection of both linear and non-linear dependencies without assuming their character a priori...

Background: Hashimoto thyroiditis (HT) is the most frequent cause of acquired hypothyroidism in paediatrics. HT is usually diagnosed in older children and adolescents, mainly in females and is rare in infants and toddlers with cardiac involvement, including pericardial effusion, that can be found in 10% to 30% of adult HT cases. In this paper, a child with HT and pericardial effusion as the most important sign of HT is described. Case presentation: A four-year-old male child suffering for a few months from recurrent abdominal pain sometimes associated with vomiting underwent an abdominal ultrasound scan outside the hospital...

Objectives: The use of growth hormone (GH) in idiopathic short stature (ISS) has been a subject of debate for the past two decades. We sought to assess the effect of GH on final height (FH) in patients with ISS in our region, which has a high consanguinity rate, and compare it to the effect observed in GH deficient (GHD) patients. Methods: We conducted a retrospective chart review from 1 January 2005 to 31 December 2013 for patients with ISS or GHD from the local United Arab Emirates population who received GH treatment and were followed-up regularly in our clinic...

Isolated Growth hormone deficiency is an important and treatable cause of short stature. However, it is often difficult to diagnose the condition with certainty due to the lack of a single robust diagnostic test. Short children, other than those with the classical phenotype of immature chubby facies, truncal obesity and micropenis in boys, or those with history of cranial lesions with known association with hypopituitarism, should be evaluated for growth hormone deficiency only after excluding the other more common conditions...
