Growth hormone (GH) research and its clinical application for the treatment of growth disorders span more than a century. During the first half of the 20th century, clinical observations and anatomical and biochemical studies formed the basis of the understanding of the structure of GH and its various metabolic effects in animals. The following period (1958-1985), during which pituitary-derived human GH was used, generated a wealth of information on the regulation and physiological role of GH - in conjunction with insulin-like growth factors (IGFs) - and its use in children with GH deficiency (GHD)...

BACKGROUND: Sudden infant death syndrome (SIDS) is a leading cause of postneonatal mortality. Genetic heart diseases (GHDs) underlie some cases of SIDS. OBJECTIVES: This study aimed to determine the spectrum and prevalence of GHD-associated mutations as a potential monogenic basis for SIDS. METHODS: A cohort of 419 unrelated SIDS cases (257 male; average age 2.7 ± 1.9 months) underwent whole exome sequencing and a targeted analysis of 90 GHD-susceptibility genes...

Congenital Isolated growth hormone deficiency (IGHD) type Ib is an autosomal recessive genetic condition caused by mutations of GH1 or the GH releasing hormone receptor (GHRH-R) gene. Affected subjects present symptoms of GHD with low but detectable levels of GH, short stature and responsiveness to GH therapy. We describe a 13-month old girl with severe growth failure who showed a low hGH in response to 2 hGH provocative tests and a modest increase of IGF-I to an IGF-I generation test. Whole exome sequencing revealed a novel homozygous variant of the GHRH-R gene (c...

PURPOSE: To examine differences in effects according to growth hormone (GH) treatment duration in adult GH-deficient patients. METHODS: In the Italian cohort of the observational Hypopituitary Control and Complications Study, GH-treated adults with GH deficiency (GHD) were grouped by duration of treatment; ≤ 2 years (n = 451), > 2 to ≤ 6 years (n = 387) and > 6 years (n = 395). Between-group differences in demographics, medical history, physical characteristics, insulin-like growth factor-I standard deviation score (IGF-I SDS) and lipid profile at baseline, last study visit and changes from baseline to last study visit were assessed overall, for adult- and childhood-onset GHD and by gender using ANOVA for continuous variables and Chi-squared test for categorical variables...

Few studies, and with controversial results, analyzed vitamin D status in children before and after growth hormone (GH) treatment. Thus, we aimed to assess vitamin D status in prepubertal children with idiopathic growth hormone deficiency (GHD), and to evaluate the effect of GHD and GH treatment on vitamin D levels. Fifty prepubertal children with isolated GHD were compared with 50 controls. All were subjected to history, anthropometric assessment and measurement of 25 hydroxyvitamin D (25(OH)D), serum calcium, phosphorous, alkaline phosphatase and parathyroid hormone (PTH) at diagnosis and 1 year after GH therapy...

We show that the equations of generalized hydrodynamics (GHD), a hydrodynamic theory for integrable quantum systems at the Euler scale, emerge in full generality in a family of classical gases, which generalize the gas of hard rods. In this family, the particles, upon colliding, jump forward or backward by a distance that depends on their velocities, reminiscent of classical soliton scattering. This provides a "molecular dynamics" for GHD: a numerical solver which is efficient, flexible, and which applies to the presence of external force fields...

Adult-onset growth-hormone (GH) deficiency (GHD) is a rare disorder, which most commonly results from pituitary or peripituitary tumors and their treatment, and is characterized by alterations in body composition, carbohydrate and lipid metabolism, bone mineral density, cardiovascular risk profile and quality of life, all of which may contribute to an increased morbidity and mortality. Since recombinant human GH (rhGH) became available in 1985, several studies have provided evidence of its beneficial effects, despite the potential risk of developing adverse effects, and much clinical experience has been accumulated...

BACKGROUND: Growth hormone (GH) treatment may unmask central hypothyroidism (CeH). This was first observed in children with GH deficiency (GHD), later also in adults with GHD due to acquired "organic" pituitary disease. We hypothesized that newly diagnosed CeH in children after starting GH treatment for nonacquired, apparent isolated GHD points to congenital "organic" pituitary disease. METHODS: Nationwide, retrospective cohort study including all children with nonacquired GHD between 2001 and 2011 in The Netherlands...

BACKGROUND: Gestational hypertensive disorders (GHDs), including gestational hypertension and preeclampsia, are associated with an increased risk of cardiovascular disease in later life, possibly through an atherogenic lipid profile. OBJECTIVE: The objective of this study is to assess if women with a previous GHD have a more atherogenic lipid profile 6 years after pregnancy compared to women with a previous normotensive pregnancy. METHODS: In a population-based prospective cohort study, we included 4933 women during pregnancy, including 302 women with a GHD...
