NCT ID: NCT01404624 Completed - Obesity Clinical Trials

Characterization of Transcriptional Regulators of Ghrelin Hormone Which Causes Genetic Obesity

Start date: January 2005
Phase: N/A
Study type: Observational

The problem point of the Prader-Willi Syndrome (PWS) patient is the obesity which is intense and the plasma ghrelin level which increases unusual from the recently PWS patients was discovered. The Ghrelin is endogeneous ligand of growth hormone secretagogue receptor with peptide hormone and the location is 3p26-p25. Becomes the secretion even from nervous system but from dignity X/A cell it is secreted mainly and growth is important even in the vagal control against food and intake and a dignity function even on the action outside which promotes the secretion which drives it operates. It increases food intake specially and in order to accomplish the action which diminishes fat utilization the obesity with the week cause which it does the mortar it is thought. Active the ghrelin of the form is essential in hormonal activity of the ghrelin and appetite and growth hormone it participates to the secretion promotion which drives. Action of the Ghrelin measuring the quantitative change in middle acylated of the PWS patient ghrelin in order to happen after the acylation initially by one interest ghrelin which is attempted the appetite of the PWS patient is is controlled the method it will be able to prove the thing directly, it used the RIA kit and the ELISA it will be able to measure kit it will be able to measure the whole ghrelin to pick the PWS patient and the blood of the normal army and active ghrelin it measured a change.

NCT ID: NCT01401244 Completed - Healthy Clinical Trials

Bioequivalence of Two Somatropin Products (Norditropin® Versus Genotropin®) in Healthy Adult Volunteers

Start date: July 14, 2011
Phase: Phase 1
Study type: Interventional

This trial is conducted in United States of America (USA). The aim of this trial is to examine the bioequivalence of Norditropin® versus Genotropin® in healthy adult volunteers.

NCT ID: NCT01298180 Completed - Clinical trials for Growth Hormone Deficiency

Is There a Sensibility Increased in the Growth Hormone at Child With Prader-Willi Syndrome?

Start date: January 2009
Phase: Phase 4
Study type: Interventional

The purpose of this study is to estimate the sensibility at the growth hormone in vivo at the children presenting a Prader-Willi syndrome (SPW) in comparison with children presenting a deficit in growth hormone (GHD).

NCT ID: NCT01038570 Completed - Clinical trials for Prader Willi Syndrome

Comparative Study Between Prader-Willi Patients Who Take Oxytocin Versus Placebo

Start date: June 2009
Phase: Phase 2
Study type: Interventional

The role of oxytocin (OT) is already known in the regulation of satiety but some clinical studies demonstrated that OT participates also in the regulation of social behavior by its implication on a better comprehension of emotion which plays a role on theory of mind and empathy. By the way, these 2 behaviors are deviants for patients with Prader-Willi Syndrome (PWS). Actually, no study was led on the effect of OT on PWS patients but Swaab and al in 1995 showed a significant reduction in number and in volume of neurons expressing OT in the paraventricular nucleus of PWS patients. Recent data were obtained studying OT in patients with autism which showed a link between the deregulation of OT and the autistic pathology. Clinical and imaging studies obtained with PWS and autistic populations make us believe that some mechanisms are common between these two pathologies. The objectives of this project are: 1. to look for an influence on the understanding of the social codes of the PWS patients, 2. to look for an influence on the behavior of stress and anxiety and on the regulation of eating habits when patients receive a nasal pulverizing of OT.

NCT ID: NCT00932932 Completed - Clinical trials for Prader-Willi Syndrome

Cortisol Activity in Patients With Prader-Willi Syndrome and Healthy Controls

Start date: February 2009
Phase: N/A
Study type: Observational

The purpose of the study is to find out if people with Prader-Willi syndrome have a difference in the protein which changes inactive cortisone to the active stress hormone cortisol.

NCT ID: NCT00800852 Completed - Obesity Clinical Trials

Increased Expression of Adiponectin Receptor 2 in the Mononuclear Cells in Children With Prader-Willi Syndrome

Start date: n/a
Phase: N/A
Study type: Observational

The inflammatory process is involved in the pathogenesis of obesity. Prader-Willi syndrome (PWS) is a genetic model of syndromic obesity. Adiponectin is an adipokine with potent anti-inflammatory properties, and its effect is mediated through adiponectin receptors 1 (adipoR1) and 2 (adipoR2). Objective of this study is to compare the expression of adipoR1, adipoR2, and adiponectin in peripheral blood mononuclear cells (PBMCs) in PWS children and obese control and to correlate receptor expression with insulin sensitivity and obesity-related parameters.

NCT ID: NCT00742664 Completed - Clinical trials for Obsessive-compulsive Disorder

Behavioral Treatment of Obsessive-Compulsive Symptoms in Youth With Prader-Willi Syndrome: A Pilot Project

Start date: September 2008
Phase: Phase 1/Phase 2
Study type: Interventional

Obsessive-compulsive (OC) symptoms are often present among youth with Prader-Willi Syndrome (PWS). They are also associated with considerable problems in the daily functioning of the child and his/her family. Although medication and behavioral treatments exist that target OC symptoms among youth without PWS, these treatments have not been thoroughly adapted for this population nor scientifically tested. Although medication has been helpful in addressing OC symptoms in several published case reports, the associated efficacy is modest and the potential for side effects is a realistic concern. Given that behavioral treatment for OC symptoms has superior efficacy to pharmacotherapy in youth without PWS without the accompanying risk for adverse side effects, it follows that an adapted version of behavioral therapy may hold promise in treating clinically problematic OC symptoms in youth with PWS. Thus, the purpose of the proposed grant is to develop and pilot-test a behavioral treatment for OC symptoms for use in youth with PWS. This study will allow us to develop and test a treatment protocol aimed at reducing OC symptoms that are clinically problematic and negatively impact functioning and quality of life in the child and his/her family.

NCT ID: NCT00705172 Completed - Clinical trials for Prader-Willi Syndrome

Retrospective Observational Study on Efficacy and Safety of Norditropin® in Children With Prader-Willi Syndrome

Start date: November 2008
Phase:
Study type: Observational

This study is conducted in Europe. The aim of this observational study is to collect data from children with Prader-Willi Syndrome, who have been treated off-label with Norditropin® for more than 12 months to seek approval for Norditropin® treatment with Prader-Willi Syndrome.

NCT ID: NCT00551343 Completed - Clinical trials for Prader-Willi Syndrome

Gut Derived Hormones, Body Composition and Metabolism in Prader-Willi Syndrome

Start date: October 2007

Study type: Interventional

The purpose of this study is to investigate the effects of a GLP-1 agonist on satiety hormones in patients with Prader-Willi Syndrome (genetic defect causing obesity).

NCT ID: NCT00474643 Completed - Obesity Clinical Trials

Correlation of Hyperghrelinemia With Carotid Artery Intima-Media Thickness in Children With Prader-Willi Syndrome

Start date: August 2006
Phase: N/A
Study type: Observational

Prader-Willi syndrome (PWS) is a genetic disorder characterized by childhood-onset obesity and endocrine dysfunction that leads to cardiovascular disability and early death within the first 3 decades of life.To assess the significance of risk factors for future disabilities, carotid artery intima-media thickness (IMT) was measured and correlated with known atherosclerotic risk factors in 27 children with PWS and 24 age-, sex-, and body mass index (BMI)-adjusted controls.
