Filter by: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.
The purpose of this study is to determine whether lengthening of both the tibiae and femora in achondroplastic patients is safe and provides reproducible outcome.
A major consequence of chronic liver disease in childhood is growth failure. This is because a chemical essential for growth called growth factor is created in the liver. Lack of response to growth hormone in people with chronic liver disease is characterized by high levels of growth hormone and low levels of growth factors. This growth hormone resistance is reflected in a variety of factors including insulin resistance and low nutritional intake. Unfortunately, growth hormone therapy has no effect for children with liver disease. In addition, failure of normal growth or malnutrition makes liver disease even worse in children, and growth hormone therapy is not likely to reverse this. A lack of proper nutrition is associated with hospitalizations and frequent complications. Poor growth is a predictor of poor outcomes after liver transplantation. Thus the management of children with liver disease remains a challenge. Children who have successful orthotopic liver transplants (OLT) show much improvement in some aspects of growth, including skin fold thickness, mid-arm circumference, and normalization of growth factor levels. However, some studies have recently reported that the growth of 15-20% of children remains poor even after a liver transplant. This can be explained by persistent abnormalities in growth factors after transplant. Growth factor was found to be a good tool for prognosis in patients with chronic liver disease. Studies showed that patients with liver cirrhosis and growth factor levels below normal values showed lower long-term survival rates compared with patients who had above normal values. This suggests that growth factor can be a good predictor of survival and early marker of poor liver function. In this case, aggressive feeding may modestly improve growth factor levels leading to improved growth but it is unlikely that effects will be optimal. The investigators propose that growth factor administration may have a positive effect that leads to better growth which is a major predictor of good outcome. To date, no reports study the use of growth factor in children with chronic liver disease. This study proposes to examine the effect of growth factor therapy in childhood chronic liver disease.
When treating very short children in puberty we are time-limited, as sex hormones cause the growth plates to fuse and growth to end. Growth Hormone (GH), plus drugs that stop puberty, increase height potential, but leave children sexually infantile at a critical time in development. Human and animal data show that estrogen, in females and males, is a principal regulator of the fusion of the growth plate in puberty. Using aromatase inhibitors (AIs), which block testosterone to estrogen conversion, in boys with different growth disorders, we have shown that AIs may have beneficial effects enhancing height potential in growth-retarded males, without affecting their puberty. However, no direct comparison of the effect of AIs alone vs. conventional GH treatment has been done to date. This study will assess the effect of AIs alone, GH alone and combination treatment in enhancing height potential in adolescent boys with idiopathic short stature.
The research aims to provide data on gender-related psychological impact of GH (Growth Hormone)treatment. Implicit measurable psychological metrics of the therapy outcome on males are to be evaluated in a Prospective Randomized Controlled Trial. As a secondary axis of the study, the investigators aim to provide descriptive documentation of the unique distress signal manifestation implicitly shown by Idiopathic Short Stature (ISS) boys and suggest methods of early detection and measurement of such manifestations that can be used to cement guidelines for the treatment in GH.
Background: - Overweight and obese children and adults often have lower levels of growth hormone in the blood. Regulation of growth hormone may be tied to weight and free fatty acids in the blood. Current tests of growth hormone (such as those used when evaluating the heights of children who are markedly shorter than other children of comparable age) may be affected by other factors, including obesity. Researchers are interested in evaluating the levels of growth hormone and free fatty acids in the blood of children between 7 and 14 years of age who weigh more than children of a comparable age, or who are shorter than other children of a comparable age and have been recommended for growth hormone testing as part of an evaluation for their height. Objectives: - To determine the effect of changes in free fatty acids in the blood on changes in growth hormone secretion in overweight or shorter children and young adolescents. Eligibility: - Children and adolescents between 7 and 14 years of age who weigh more than or are shorter than other children of a comparable age and do not have any medical illnesses. Design: - Participants will have two study visits, one of which will be a half day screening visit in the outpatient clinic and one of which will require 2 nights as an inpatient at the National Institutes of Health Clinical Center. - Participants should not eat or drink anything except water after 10 PM the night before or on the morning of the screening visit. - At the screening visit, participants will have a physical examination and medical history, provide blood and urine samples, have an oral glucose tolerance test (to check blood sugar levels), and have an x-ray of the left hand to check bone age. - The inpatient study visit will involve a physical examination and medical history, a full x-ray scan to study body fat and muscle, frequent blood tests throughout the visit, and various medications to stimulate growth hormone production and lower levels of free fatty acids in the blood.
This is an open-label, prospective, multicentric, non-comparative, non-randomized Phase IV interventional study in which subjects pre-diagnosed with Growth Hormone Deficiency (GHD) were treated for 4 weeks with Saizen to compare the response between GHD children born appropriate for gestational age (AGA) and those born small for gestation age (SGA) after 4 weeks of Saizen therapy.
This was a 48-week, open-label, prospective, multicentric, randomised, comparative with parallel control, Phase 4 study to evaluate the effects of Saizen on cardiac function in GHD subjects during the transition phase from childhood to adulthood. The study was designed to evaluate whether recombinant-human growth hormone (r-hGH) treatment also benefits young subjects with GHD. Some trials have already been published on this subject, but they were mainly focused on the bone density.
This study is conducted to describe the efficacy and safety of recombinant human growth hormone (r-hGH) treatment Saizen® on children with hypochondroplasia.
This study is conducted in Japan. The aim of this observational study is to collect information about the safety and efficacy of Norditropin® in the long-term treatment of patients with a SGA (small for gestational age) short stature where the growth plate in the long bones (epiphyseal disc) is not closed. An extension to the GHLIQUID-1517 trial (NCT00184717).
