    Diagnostic Usefulness of Insulin-Like Growth Factor 1 and Insulin-Like Growth Factor Binding Protein 3 in Children with Suspected Pituitary Dwarfism.
    Clin Lab 2018 May;64(5):759-765
    Background: Pituitary dwarfism (also known as short stature) is a medical condition in which the pituitary gland does not produce enough growth hormone (GH). To confirm the diagnosis of growth hormone deficiency the overnight profile of GH secretion and GH provocative tests are usually performed; however, due to wide GH fluctuations throughout the day and night and the invasiveness of stimulation tests, their clinical utility is limited. Therefore, screening for IGF-1 (insulin-like growth factor 1) and IGFBP-3 (insulin-like growth factor binding protein type 3) is proposed, suggesting that these tests provide a more accurate reflection of the mean plasma GH level, although the results of these tests are still problematic.

    Background: The effect of gene expression data on diagnosis remains limited. Here, we show how diagnosis and classification of growth hormone deficiency (GHD) can be achieved from a single blood sample using a combination of transcriptomics and random forest analysis.

    Methods: Prepubertal treatment-naive children with GHD (n = 98) were enrolled from the PREDICT study, and controls (n = 26) were acquired from online data sets. Read More

    Effects of recombinant human growth hormone administration on cardiovascular risk factors in obese children with relative growth hormone deficiency.

    Department of Pediatrics, Shandong Provincial Hospital Affiliated to Shandong University, 9677 Jingshi Road, Jinan, 250021, Shandong, China.
    Background: Based on the sample of obese children with relative growth hormone deficiency (GHD), the objective of our study was to determine the effects of rhGH treatment on cardiovascular risk factors, including body mass index (BMI), lipid levels and glucose metabolism index.

    Methods: A total of 43 obese children with relative GHD were included in our final analysis. The obese subjects were divided into two groups: recombinant human growth hormone (rhGH) treatment group and untreated control group. Read More

    Utility of serum IGF-1 for diagnosis of growth hormone deficiency following traumatic brain injury and sport-related concussion.
    BMC Endocr Disord 2018 Apr 2;18(1):20. Epub 2018 Apr 2.
    Division of Endocrinology, Department of Medicine, Cumming School of Medicine, University of Calgary, 1820 Richmond Rd SW, Calgary, AB, T2T 5C7, Canada.
    Background: Growth hormone deficiency (GHD) is a potential consequence of traumatic brain injury (TBI), including sport-related concussion (SRC). GH stimulation testing is required for definitive diagnosis; however, this is resource intensive and can be associated with adverse symptoms or risks. Measurement of serum IGF-1 is more practical and accessible, and pituitary tumour patients with hypopituitarism and low serum IGF-1 have been shown to have a high probability of GHD. Read More

    Design of the long-term observational cohort study with recombinant human growth hormone in Korean children: LG Growth Study.
    Ann Pediatr Endocrinol Metab 2018 Mar 22;23(1):43-50. Epub 2018 Mar 22.
    Department of Pediatrics, Korea University Anam Hospital, Seoul, Korea.
    Purpose: Regarding recombinant human growth hormone (rhGH) use in the pediatric population, no long-term follow-up data are available for Korean patients. To fill in the gap of knowledge, a registry study (LG Growth Study) was initiated to assess the safety and effectiveness of four types of rhGH products in real-life settings.

    Methods: A total of 4,000 children will be registered and prospectively followed up at 6-month intervals until 2 years after epiphyseal closure to collect data on treatment and adverse events, with primary interest in malignancies and growth outcomes. Read More

    Direct and indirect effects of Growth Hormone Deficiency (GHD) on lung function in children: A mediation analysis.

    National Research Council of Italy, Institute of Biomedicine and Molecular Immunology, Palermo, Italy; Department of Science for Heath Promotion and Mother and Child Care, University of Palermo, Italy.
    Background: Studies on pulmonary function tests (PFTs) in Growth Hormone Deficiency (GHD) children are lacking. The aims of this study were: (i) to investigate PFTs in GHD pre-pubertal children with respect to Controls, before starting Growth Hormone Therapy (GHT) (T0); (ii) to evaluate changes of PFTs in GHD vs Controls, after 1-year GHT (T1). For both aims the mediation analysis (MA) was applied to evaluate the extent to which the relationship between GHD and PFTs could be ascribed to a height-mediated (indirect) or a GH direct effect.

    Biomarkers of GH action in children and adults.
    Growth Horm IGF Res 2018 Mar 20;40:1-8. Epub 2018 Mar 20.
    Department of Endocrinology and Internal Medicine, Aarhus University Hospital, Aarhus, Denmark.
    Growth hormone (GH) and IGF-I levels in serum are used as biomarkers in the diagnosis and management of GH-related disorders but have not been subject to structured validation. Auxological parameters in children and changes in body composition in adults, as well as metabolic parameters and patient related outcomes are used as clinical and surrogate endpoints. New treatment options, such as long acting GH and GH antagonists, require reevaluation of the currently used biochemical biomarkers. Read More

    Chitayat-Hall and Schaaf-Yang syndromes:a common aetiology: expanding the phenotype of -related disorders.
    J Med Genet 2018 May 29;55(5):316-321. Epub 2018 Mar 29.
    Division of Clinical Genetics and Metabolism, Department of Pediatrics, The Hospital for Sick Children, Toronto, Ontario, Canada.
    Background: Chitayat-Hall syndrome, initially described in 1990, is a rare condition characterised by distal arthrogryposis, intellectual disability, dysmorphic features and hypopituitarism, in particular growth hormone deficiency. The genetic aetiology has not been identified.

    Methods And Results: We identified three unrelated families with a total of six affected patients with the clinical manifestations of Chitayat-Hall syndrome. Read More
