Background: Aggrecan (ACAN) is a proteoglycan found in the extracellular matrix of articular and growth plate cartilage. Animal studies have shown that mutations in the ACAN gene lead to premature hypertrophic chondrocyte maturation, causing accelerated cartilage ossification. Patients with ACAN deficiency present with dominantly inherited short stature, often with advanced skeletal maturation and premature growth cessation, as well as early-onset joint diseas...

Introduction: Accumulating evidence indicates various but significant effects of human milk IGF1 (HMIGF1) on infantile and childhood linear growth and weight gain. Studies on maternal factors affecting the level of HMIGF1 need to be clarified.Objectives and Methods: We performed electronic literature systematic review using PubMed, Google Scholar, and Web of Sciences with the aim to provide an update on maternal factors ...

Background: Growth hormone (GH) therapy typically involves daily administration of recombinant-human growth hormone (r-hGH) injections over many years. Long-term treatment attracts substantial costs due to the regular usage of injector pens. We conducted a study to understand the environmental impact of reusable and disposable GH injector pens.Aim: To assess environmental sustainability of Aluetta® reusabl...

Thyroid dysgenesis (TD) is the most common cause of congenital hypothyroidism in iodine sufficient regions. TD includes a broad spectrum of developmental anomalies varying from absence of thyroid (athyreosis) to an abnormally located thyroid (ectopy), small (hypoplasia) or asymmetric thyroid. Thyroid dysgenesis is usually sporadic, but up to 2% of cases is familial. Genetics of TD is complex and advances in developmental biology over the past two decades revealed monogenetic f...

Background & objective: Maturity-onset diabetes of the young (MODY) is a monogenic form of diabetes that is characterized by an early onset, autosomal dominant mode of inheritance and a primary defect in pancreatic β-cell function. MODY has been identified in Asian populations, however, there is a big discrepancy in the genetic locus between Asian and Caucasian patients with MODY. We previously reported that mutations in PTPRD, SYT9 and WFS1 have been identified in Ko...

Keywords: Sleep-Related Breathing Disorders, recombinant human Growth Hormone treatment, Prader–Willi syndrome, Toddlers.Background: Recombinant human growth hormone (rhGH) therapy is beneficial for children with Prader–Willi syndrome (PWS) in improving short stature and metabolism, but the effect of early rhGH treatment on respiratory and sleep parameters for the PWS children under three years old remains el...

Male reproductive disorders are common and there is evidence for increasing incidence over recent decades. These disorders may present at birth (hypospadias and cryptorchidism) or in adulthood (infertility, testicular cancer) and can arise as a result of underlying genetic abnormalities or following environmental (e.g. phthalates) and pharmaceutical (e.g. analgesics, chemotherapy) exposures that impact fetal, neonatal of prepubertal testicular development. Understanding the re...

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Background: CinnaTropin® (CinnaGen, Iran) is a recombinant human GH manufactured in Iran. Herein, we compared the efficacy and safety of the CinnaTropin® with the corresponding reference (Nordilet® Norditropin, Novo Nordisk, Denmark) in children with idiopathic GH deficiency (IGHD) and multiple pituitary hormone deficiency (MPHD).Methods: This was a randomized, open-label and cross-over study. Eligible pati...

Introduction: Genetic markers associated with the response to recombinant human GH (r-hGH) have been identified in Growth Hormone Deficiency (GHD) and Turner Syndrome (TS) children in the PREDICT long-term follow-up (LTFU) prospective study (NCT00699855).1 A validation (VAL) study (NCT01419249) was conducted to confirm association.Methods/design: Inclusion criteria for GHD and TS children were identical in the LTFU and VAL studies (GHD defined...
