Active clinical trials for "Diabetes Insipidus"

The purpose of this study is to investigate the treatment and natural history of pituitary disease. We have a longstanding interest in pituitary disease including acromegaly, central diabetes insipidus, and nonfunctioning pituitary adenoma. We will continue to follow patients and recruit new patients for treatment and follow-up. Blood and pituitary tumor tissue (when available through clinical care) will be saved for future analyses related to pituitary disease.

This is a randomized, double-blind, placebo-controlled crossover pilot study of single-dose intranasal oxytocin (4 IU and 24 IU) in 18-60-year-old men and women with central diabetes insipidus to evaluate the effect of oxytocin on anxiety, depression and socioemotional functioning. Following a screening visit to determine eligibility, participants will return for three main study visits. During the main study visits, study participants will receive either oxytocin or placebo, followed by assessments of emotional behavior. Thirty participants will be equally randomized to one of six possible drug orders: 4 IU oxytocin - 24 IU oxytocin - placebo 4 IU oxytocin - placebo - 24 IU oxytocin 24 IU oxytocin - 4 IU oxytocin - placebo 24 IU oxytocin - placebo - 4 IU oxytocin placebo - 4 IU oxytocin - 24 IU oxytocin placebo - 24 IU oxytocin - 4 IU oxytocin

The purpose of this study is to determine whether metformin can increase urine concentration (osmolality) and decrease the amount of urine in patients with congenital nephrogenic diabetes insipidus (NDI).

The aim of this study is to assess the impact of endocrine changes and their correction on survival and organ function in heart and lung transplant recipients. This study also features an investigation of the hormone levels and hormonal replacement therapy of the donors to study its role in the function of the transplanted hearts and lungs. Thyroid hormones (TSH, thyroxine, tri-iodothyronine), cortisol and the antidiuretic hormone will be studied. The former two hormone levels will be defined in the recipients just before transplantation and three days later. In the case of the donors all three hormones will be recorded at the time of the explantation. The investigators would like to record the hormonal replacement therapy in all our patients as well to see it's effect on survival and on the transplanted organ function. After the transplantation during the hospital stays all the important hemodynamic parameters, laboratory parameters, the result of the medical imagings, the medication, the length of ICU and hospital stay and the complications were recorded. Recipients will be followed for five years. Organ function will be assessed every three month for a year, after than every six month for further four years. Investigator would like to record the result of the cardiac echocardiography, spirometries, imaging, and complications. Our purpose is to compare these results against the endocrine disorders and the replacement therapy.

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, melatonin has shown to increase OT release. This study is designed to evaluate oxytocin values after administration of melatonin in adults (healthy volunteers and patients with hypopituitarism). The investigators hypothesize that OT response will be blunted following melatonin in patients with hypopituitarism compared to healthy controls.

Lithium therapy is cornerstone in therapy of bipolar disorders. A well known side-effect of lithium therapy is a urinary concentration defect which manifests in it's most severe form as nephrogenic diabetes insipidus. The development of urinary concentration defects and its progression to nephrogenic diabetes insipidus in the population of lithium treated patients is unknown and therefore this study aims to evaluate the decline of urinary concentration defects in a Dutch population of lithium treated patients. In this prospective cohort study, 51 participants treated with lithium at Canisius Wilhelmina Hospital, Nijmegen and included in the previous study in 2012 will be approached to undergo a follow-up dDAVP-test.

The objective of this study is to investigate the efficacy and safety of tolvaptan based on the change in serum sodium concentration following administration of tolvaptan oral tablets at 7.5 to 60 mg/day for up to 30 days in patients with hyponatremia in the SIADH.

The study is designed to assess the efficacy of an investigational drug called SR121463B (vasopressin receptor antagonist) in the treatment of low levels of sodium in the blood associated with the Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH). This double blind period study is followed by 2 open label extension studies with flexible doses of satavaptan.

Glucagon like Peptide -1 (GLP-1) receptor agonists are well known to stimulate glucose-induced insulin secretion and to reduce energy intake. Recent findings from animal and human studies suggest a role of GLP-1 in regulating water and salt homeostasis. GLP-1 has been shown to reduce fluid intake after an oral salt load or during a meal - pointing to a hypodipsic effect. The aim of this study is to elucidate whether these putative hypodipsic properties of GLP-1 might be of advantage in persons with an exaggerated thirst perception as is the case in patients with primary polydipsia.

This is an open-label dose-titration study in Japanese Central Diabetes Insipidus (CDI) patients designed to demonstrate the efficacy and safety of orally-disintegrating tablet of desmopressin.
