Filter by:The purpose of the protocol is to describe the distribution of IGF-1 deficiency in the studied population of Idiopathic Short Children without Growth Hormone Deficiency or any other identified cause of short stature and not treated with recombinant Growth Hormone or IGF-1
This is a two arm, randomized, prospective, intervention study in order to determine the effects of growth hormone treatment on eating regulation and to compare between the growth responses with or without nutritional intervention in short stature children. The study will include 30 short stature children that are about to initiate growth hormone treatment and will last for one year. After 4 months of treatment, children will be randomized into two groups: 1. Control group that will continue with growth hormone treatment without any other intervention. 2. Study group that will be a given a nutritional intervention in addition to growth hormone treatment. At screening visit and during the study the following parameters will be evaluated: height, weight, growth markers in the blood and urine, child eating behavior questionnaire, blood tests, hormonal tests and resting energy expenditure measurements.
Growth hormone therapy will improve the height of short statured children with pathological conditions that lead to growth retardation. Growth hormone therapy will show an increase in height velocity >1 SD compared to pretreatment height velocity. and the therapy will be safe.
The purpose of the study is to understand the effect of rhGH therapy on hepatic drug metabolism in children with idiopathic growth hormone deficiency.
One arm, open, prospective, intervention study to assess biochemical markers of growth response to Growth Hormone treatment in 20 Children, aged 3-9 years old, with idiopathic short stature. All participants will be treated with Growth Hormone during the first year of the study (and then in accordance with the local ethic requirement, to supply drug which is not approved for the indication used in the study, for additional 3 years) and then will be followed up for the next 3 years. The impact of Growth Hormone therapy on clinical laboratory parameters that are indicative of the growth response will be assessed by collecting blood and urine samples during the 4 years study period. The primary endpoints are measurements of height and growth velocity during the year of Growth Hormone treatment, the height at the beginning of puberty and final height. Secondary endpoints are psychological parameters, assessed by questionnaires.
To examine the clinical genetic and biochemical characteristics of children with growth hormone deficiency.
The protein polymorphism of the growth hormone receptor characterized by the genomic deletion of exon 3 has been linked to the magnitude of the first-year-growth response to growth hormone (GH) in girls with Turner syndrome. Objective: to study the long-term effect of GH therapy in Turner syndrome in correlation to this GHR polymorphism in a mainly retrospective design (chart-review).
To demonstrate that an individualized, formula-based Genotropin regimen for children with Idiopathic Short Stature will lead to a targeted height gain (to reach the target of 10th percentile (%), or -1.3 SDS) during 24 months of treatment. The endpoint at 4 years is to explore treatment efficiency over four years of two formula-based dose regimens (sub-arms) compared to standard treatment
Objective: This study is designed to determine whether growth hormone treatment in children 8 to 18 years of age alters function of the lining of the arteries. This may play a role in increasing or decreasing the risk of heart disease. Methods. Twenty children, for whom growth hormone therapy will be otherwise provided, will be studied before and 3 months after starting growth hormone. Subjects can be on other hormonal replacements but no other medications. Each study will be done in the fasting state. The blood vessel function will be determined by measuring the change in forearm blood flow before and after blocking flow to the arm for 5 minutes. Blood will be drawn after the test to measure glucose, insulin and fats.
The present randomized trial was initially intended to study the benefits of a combined treatment with growth hormone (GH) and a gonadotropin-releasing hormone (GnRH) agonist for pubertal children with idiopathic short stature. However, treatments were stopped in January 2012 at the request of the French drug agency. Therefore, a protocol amendment divided the study in two study periods. Study Period 1 involved combined treatment with somatropin and leuprorelin or treatment with somatropin alone. Participants from France who participated in this Period 1 of the study were asked to participate in a long term safety follow up defined as a Period 2 of the study. Participants from the Netherlands were offered participation in Genetics and Neuroendocrinology of Short Stature International Study (GeNeSIS, clinicaltrials.gov Identifier: NCT01088412) for long term safety follow up independent of this study.
