Growth hormone deficiency (GHD) results from variations affecting the production and release of growth hormone (GH) and is of 2 types: isolated growth hormone deficiency (IGHD) and combined pituitary hormone deficiency (CPHD). IGHD results from mutations in GH1 and GHRHR while CPHD is associated with defects in transcription factor genes PROP1, POU1F1, and HESX1. The present study reports on screening of POU1F1, PROP1, and HESX1 in CPHD patients and the novel variations identified. Fifty-one CPHD patients from 49 unrelated families clinically diagnosed on the basis of biochemical and imaging investigations along with 100 controls were enrolled...

Daily subcutaneous injection of human growth hormone has been used for the treatment of growth hormone deficiency and growth failure but has led to poor patient compliance and renal toxicity. Thus, it is crucial to develop favorable growth hormone delivery systems to improve patient compliance. In the present study, to increase the oral bioavailability of growth hormone and improve patient compliance, enteric-coated capsules filled with monomethoxyl poly(ethylene glycol)-b-poly(L-lactide-co-glycolide) nanoparticles were prepared to facilitate oral growth hormone delivery...

CONTEXT: Klotho is an aging-modulating protein expressed mainly in the kidneys, which can be cleaved and shed to act as a circulating hormone. Several lines of evidence suggest a tight interaction between klotho and the GH-IGF-I axis. We showed previously that klotho levels are decreased in pediatric patients with growth hormone deficiency (GHD). Our aim now is to investigate the effect of GH therapy on klotho levels in these patients and to elucidate the role of IGF-1 in mediating secretion of klotho...

Mitochondria are critical organelles for endocrine health; steroid hormone biosynthesis occurs in these organelles and they provide energy in the form of ATP for hormone production and trafficking. Mitochondrial diseases are multisystem disorders that feature defective oxidative phosphorylation, and are characterized by enormous clinical, biochemical and genetic heterogeneity. To date, mitochondrial diseases have been found to result from >250 monogenic defects encoded across two genomes: the nuclear genome and the ancient circular mitochondrial genome located within mitochondria themselves...

Despite recent advances in acromegaly treatment by surgery, drugs, and radiotherapy, hormonal control is still not achieved by some patients. The impairment of IGF-1 generation by estrogens in growth hormone deficient patients is well known. Patients on oral estrogens need higher growth hormone doses in order to achieve normal IGF-1 values. In the past, estrogens were one of the first drugs used to treat acromegaly. Nevertheless, due to the high doses used and the obvious side effects in male patients, this strategy was sidelined with the development of more specific drugs, as somatostatin receptor ligands and dopamine agonists...

A 19-month-old boy was referred for progressive weight gain. His past medical history included congenital hypothyroidism and developmental delay. Physical examination revealed characteristics of Albright Hereditary Osteodystrophy, macrocephaly, and calcinosis cutis. He had hypocalcemia, hyperphosphatemia, and elevated Parathyroid Hormone levels. Genetic testing revealed a known mutation of GNAS gene, confirming the diagnosis of Pseudohypoparathyroidism Type Ia (PHP-Ia) (c.34C>T (p.G1n12X)). He had a normal brain MRI at three months, but developmental delay prompted a repeat MRI that revealed Chiari Malformation Type I (CM-I) with hydrocephalus requiring neurosurgical intervention...

Many countries have established regulations regarding growth hormone (GH) treatment in children, to standardise care and reduce cost. In this study, we describe current practice in Ireland surrounding child measurement and the approach to diagnosis of GH deficiency. A questionnaire was sent to 139 paediatricians in Ireland and 35 (9 paediatric endocrinologists) responded. Only 13 (37.1%) use the recommended 2-person technique for measuring children under 2. Amongst GH prescribers, there were a variety of GH Stimulation Tests used, sex steroid priming was used by 8 (80%) and the general cut off for a passed test was consistent (7ng/ml)...

Growth hormone (GH) is a naturally occurring polypeptide hormone produced by somatotropic cells in the anterior pituitary. The main function of somatotropin is stimulation of linear growth, but it also affects carbohydrate metabolism, increases bone mass and has potent lipolytic, antinatriuretic and antidiuretic effects. Growth hormone deficiency (GHD) may occur both in children and in adults. At the moment there is no gold standard for the diagnosis of GHD, and the diagnosis should take into account clinical, auxological, biochemical and radiological changes and, if necessary, genetic testing...

OBJECTIVE: Growth hormone deficiency (GHD) is the most common cause for childhood dwarfism. Currently, the significance of insulin-like growth factor-1 (IGF-1) in diagnosis of GHD is still debatable. Due to the possible correlation between leptin (LEP) and GHD pathogenesis, this study investigated the gene polymorphism of LEP and its receptor (LEPR) genes, along with serum IGF-1 and LEP levels in GHD patients. This study attempted to illustrate the correlation between gene polymorphism and GHD pathogenesis...

OBJECTIVE: Experimental models demonstrate an important role of GH in retinal development. However, the interactions between GH and the neuro-vascularization of the human retina are still not clear. A model of untreated congenital isolated GH deficiency (IGHD) may clarify the actions of GH on the retina. The purpose of this work was to assess the retinal neuro-vascularization in untreated congenital IGHD (cIGHD). DESIGN: In a cross sectional study, we performed an endocrine and ophthalmological assessment of 25 adult cIGHD subjects, homozygous for a null mutation (c...
