Filter by:The aim of the study is to determine the specificity and sensitivity of the combined growth hormone releasing hormone (GHRH) + Arginine test in healthy volunteers, subjects with highly probable adult growth hormone deficiency (AGHD) and subjects who were probably free of AGHD.
The primary objective of the trial was to assess the bioequivalence for two concentrations (5.83 mg/mL and 8 mg/mL) of the new r-hGH liquid multidose formulation using the r hGH freeze-dried multidose formulation (Saizen® 8 mg, 8.8 mg/1.51 mL) as reference. Each volunteer received three r hGH treatments, with each treatment being administered as a single subcutaneous dose of 4 mg r-hGH in a randomized sequence with at least one week of wash-out period between successive treatments.
The purpose of this study is to obtain psychological response and user preference information on the use of the T jet® device versus the traditional subcutaneous injection administration of Tev Tropin®. This study will compare subject-reported injection anxiety immediately before the administration of each dose of Tev-Tropin® between a needle-syringe injection method and a needle-free injection method (T-jet®)
To test the hypothesis that both lack and excess of growth hormone (GH) is associated with cardiac abnormalities. Cardiac function and morphology will be evaluated by MRI before and after treatment.
This observational study is conducted globally. The aim of the study is to investigate the effectiveness and safety of real-life treatment with Norditropin®. The study population will consist of children and adults who are on treatment with Norditropin® in accordance with normal clinical practice.
Fifteen to twenty percent of adults who suffer a traumatic brain injury (TBI) that requires hospitalization and rehabilitation have been found to have growth hormone (GH) deficiency by GH stimulation testing. Moreover, abnormalities have also been established for the cortisol and thyroid axis. The hypothesis of this proposal is that hormone replacement in TBI patients with documented abnormalities in the GH, thyroid, or cortisol axis will improve muscle function, body composition, aerobic capacity (GH) and tests of neuropsychologic function (GH, thyroid, cortisol).
The purpose of this study is to compare the effectiveness of low dose human chorionic gonadotropin (HCG) in combination with clomiphen citrate to induce ovulation and its endocrine response in patients who had previously failed to ovulate on clomiphen citrate alone. The investigators will also compare the effectiveness and endocrine response of this approach with the regimen of adding HMG to clomiphen citrate.
The aim of the study is to investigate changes in insulin sensitivity and ß-cell function after 24 and 48 weeks of low-dose growth hormone (GH) therapy in adult patients with severe GH deficiency using highly standardized techniques. Insulin sensitivity was estimated using euglycemic, hyperinsulinemic clamps, while insulin secretion and hepatic insulin clearance were determined by changes in insulin and C-peptide levels during hyperglycemic hyperinsulinemic clamps with consecutive intravenous (i.v.) L-arginine stimulation tests. Moreover, the researchers investigated changes in body composition, lipolysis and cardiovascular risk markers. Furthermore, in order to verify the mechanisms involved in the pathogenesis of GH-induced insulin resistance and the GH-induced improvement in insulin resistance under long term treatment, the researchers intend to establish changes in intramyocellular lipid (IMCL) in patients with GH deficiency by magnetic resonance (MR)-spectroscopy before and during GH-treatment and to correlate IMCL with insulin resistance, insulin secretion and insulin clearance. Finally, the researchers aim to justify the effect of GH on adiponectin secretion as well as on the 11-ß hydroxylase activity.
Objective 1: To assess environmental exposure to chemicals/toxins, including phthalates, among rural and urban Mexican American men and women (n=300), aged 18 to 40, in urban Baytown, TX and rural Rio Grande Valley (Hidalgo County) communities along the Texas-Mexico border region via survey. Objective 2: To determine generational sex ratio trends in urban Baytown, TX and along the rural Rio Grande Valley (Hidalgo County) utilizing vital statistics data from the Texas Department of Health and the Center for Health Statistics. Objective 3: To measure urinary phthalate levels and self-reported phthalate exposure in Mexican American men and women from urban Baytown, Texas and rural communities along the lower Rio Grande Valley (Hidalgo County) on theTexas-Mexico border. To conduct an optional procedure, chromosomal sex determination, among a subgroup of 50 persons (13 men + 12 women in each community) from participants who complete the survey in Objective 1.
This trial is set up to compare Zomacton to Genotropin for the treatment of growth hormone deficiency in children. The children will be treated for 1 year. Half of the patients will be treated with Genotropin and half with Zomacton. During this time they will be dosed every day by themselves or their parents at home in the evening. There will be 138 patients in the trial from age 3 to age 11. The patients cannot have been treated before with growth hormone and the patients must have a proven growth hormone deficiency, this will be shown by a specific test that will be performed before the trial in the local clinic and once during the trial. During the time of the treatment the patients will come to visit the clinic every 3 months. At these visits their heights will be measured, blood samples will be taken, physical examinations will be performed and questions about their health will be asked. At 2 times in the trial they will have a hand x-ray taken to measure the bone age. At the end of the trial the patients will stop the treatment and continue on one of the marketed products available to treat growth hormone deficiency.
