NCT ID: NCT06217848 Recruiting - Craniopharyngioma Clinical Trials

The Effect of GLP-1 Agonist in Patients With Hypothalamic Obesity: Prospective, Pilot Study

Start date: November 28, 2022
Phase: Early Phase 1
Study type: Interventional

GLP-1 analogs are used as agents in the existing treatment of obesity. However, there are lack of previous reports on the effectiveness and role of GLP-1 analogs in the development of obesity traits in patients with functionally impaired hypothalamus. With this preliminary study, the investigators would explore the role of GLP-1 analogues to identify eating behavioral pathology subtype differences in the therapeutic efficacy of GLP-1 analogues in hypothalamic obesity patients. This will allow us to identify the role of specific nuclei which could be the pathogenesis of hypothalamic obesity. Our hypotheses: GLP-1 analogs will effectively induce weight loss in patients with hypothalamic obesity, and different subtypes of hypothalamic obesity will respond differently to GLP-1 analogs.

NCT ID: NCT04902235 Completed - Social Isolation Clinical Trials

Identification and Clinical Relevance of an Oxytocin Deficient State (CRH Study)

Start date: July 6, 2021
Phase: Phase 4
Study type: Interventional

Oxytocin (OT) is a hypothalamic peptide that enters the peripheral circulation via the posterior pituitary gland. OT plays a key role in regulating appetite, psychopathology, prosocial behavior and sexual function. Hypopituitarism is associated with increased obesity, increased psychopathology, sexual and prosocial dysfunction despite appropriate hormone replacement. A few studies suggest the existence of a possible OT deficient state in hypopituitarism. In animal models, corticorelin hormone (CRH) has shown to increase OT release. This study is designed to evaluate oxytocin values after administration of CRH in adults (healthy volunteers and patients with hypopituitarism). The investigators hypothesize that OT response will be blunted following CRH in patients with hypopituitarism compared to healthy controls.

NCT ID: NCT04897802 Recruiting - Social Isolation Clinical Trials

Identification and Clinical Relevance of an Oxytocin Deficient State (GLP1 Study)

Start date: September 13, 2021
Phase: Phase 4
Study type: Interventional

Oxytocin (OT) is a hypothalamic peptide that enters the peripheral circulation via the posterior pituitary gland. OT plays a key role in regulating appetite, psychopathology, prosocial behavior and sexual function. Hypopituitarism is associated with increased obesity, increased psychopathology, sexual and prosocial dysfunction despite appropriate hormone replacement. A few studies suggest the existence of a possible OT deficient state in hypopituitarism. In animal models, glucagon-like peptide 1 (GLP1) has shown to increase OT release. This study is designed to evaluate OT values after administration of GLP1 in adults (healthy volunteers and patients with hypopituitarism). The investigators hypothesize that OT response will be blunted following GLP1 receptor agonist (GLP1-RA) in patients with hypopituitarism compared to healthy controls.

NCT ID: NCT00373386 Completed - Clinical trials for Growth Hormone Deficiency

Growth Hormone and Endothelial Function in Children

Start date: January 2005
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT00144404 Withdrawn - Panhypopituitarism Clinical Trials

Baseline Sexual Function, Cognitive Function, Body Composition and Muscle Parameters and Pharmacokinetics of Transdermal Testosterone Gel in Women With Hypopituitarism

Start date: August 2002
Phase: N/A
Study type: Observational

The purpose of this study is to determine the blood levels of testosterone gel administered for a week to women with hypopituitarism and determine if this leads to testosterone replacement in a normal range for women. An additional objective is to determine the baseline laboratory abnormalities and physical, brain function, emotional and sexual symptomatology of these women with hypopituitarism.

NCT ID: NCT00144391 Recruiting - Panhypopituitarism Clinical Trials

Testosterone Gel Applied to Women With Pituitary Gland Problems

Start date: July 2003
Phase: Phase 4
Study type: Interventional

The principal aim of this study is to evaluate if application of testosterone gel leads to improvement in measures of sexual function, thinking ability and quality of life in women with dysfunction of the pituitary gland. A secondary purpose is to determine the effects of testosterone replacement on body composition and muscle function and strength.

NCT ID: NCT00001595 Recruiting - Cushing Disease Clinical Trials

An Investigation of Pituitary Tumors and Related Hypothalmic Disorders

Start date: April 21, 1997
Phase:
Study type: Observational

There is a variety of tumors affecting the pituitary gland in childhood; some of these tumors (eg craniopharyngioma) are included among the most common central nervous system tumors in childhood. The gene(s) involved in the pathogenesis of these tumors are largely not known; their possible association with other developmental defects or inheritance pattern(s) has not been investigated. The present study serves as a (i) screening/training, and, (ii) a research protocol. As a screening and training study, this protocol allows our Institute to admit children with tumors of the hypothalamic-pituitary unit to the pediatric endocrine clinics and wards of the NIH Clinical Center for the purposes of (i)<TAB>training our fellows and students in the identification of genetic defects associated with pituitary tumor formation, and (ii)<TAB>teaching our fellows and students the recognition, management and complications of pituitary tumors As a research study, this protocol aims at (i)<TAB>developing new clinical studies for the recognition and therapy of pituitary tumors; as an example, two new studies have emerged within the context of this protocol: (a) investigation of a new research magnetic resonance imaging (MRI) tool and its usefulness in the identification of pituitary tumors, and (b) investigation of the psychological effects of cortisol secretion in pediatric patients with Cushing disease. Continuation of this protocol will eventually lead to new, separate protocols that will address all aspects of diagnosis of pituitary tumors and their therapy in childhood. (ii)<TAB>Identifying the genetic components of pituitary oncogenesis; those will be investigated by (a) studying the inheritance pattern of pituitary tumors in childhood and their possible association with other conditions in the families of the patients, and (ii) collecting tumor tissues and examining their molecular genetics. As with the clinical studies, the present protocol may help generate ideas for future studies on the treatment and clinical follow up of pediatric patients with tumors of the pituitary gland and, thus, lead to the development of better therapeutic regimens for these neoplasms.
