Active clinical trials for "Diabetes Insipidus"

The purpose of this study is to determine whether the combination of copeptine and troponin adds diagnosis information to that provided by troponin alone or the combination of troponin and myoglobin. Hypothesis : If the values of troponin and copeptin are not elevated, diagnosis of acute myocardial infarction can be ruled out without prolonged monitoring and serial blood sampling.

This study investigates stimulation of the posterior pituitary gland by oral Macimorelin (a ghrelin receptor Agonist) to be a novel diagnostic test in the polyuria-polydipsia syndrome.

The study aim is to assess whether premedication with midazolam prior to surgery affects copeptin concentration in blood.

An acute psychotic episode is a severe psychiatric syndrome which might occur in different psychiatric diagnoses. The outcome prediction of relapse rate of a psychotic episode within a certain time frame is difficult and depends on many factors. More and better predictors are required to improve the outcome prediction in order to adjust therapy and follow-up if patients suffer from this acute disease. Copeptin, a surrogate marker for vasopressin, has been proven helpful in the prediction of the outcome in serious somatic diseases. Additionally, a rise of copeptin due to psychological stress was shown. The aim of this study is to investigate the association of the neuroendocrine biomarker copeptin and the prediction of the onset of psychotic episode within one year.

This study evaluates the usefulness of pro-adrenomedullin (precursor of a vasodilatory peptide involved in septic shock pathogenesis) and copeptin (a stable peptide of the arginine vasopressin precursor) to predict, at the moment of septic shock diagnosis or their changes at 6 hours, the vasopressor requirements (measured by inotropic index and vasopressor dependency ratio) and volume requirement for resuscitation.

The relationship of uterine contractions on fetal copeptin levels in umbilical cord blood is studied.

The purpose of this study is to evaluate the effectiveness of a peer-to-peer program (P2P) in addition to Shared Medical Appointments (SMAs) compared to SMAs alone for the treatment of diabetes in five VA health systems, and to study the implementation process in order to gather information required to disseminate the program more broadly in the VHA system.

Prospective observational multicenter study to evaluate copeptin as a prognostic marker in patients with an acute cerebrovascular event. It includes four groups of patients, mainly depending on type of initial therapy (intra-arterial thrombolysis, intravenous thrombolysis, conservative treatment, TIA). The study takes place at the Emergency and neurological Department of the University of Bern, Switzerland; Department of Neurology, Goethe University of Frankfurt a.M. (Germany). Further participating centers are under discussion

Patients with severe infection can develop very low blood pressure. There are many mechanisms leading to this, and one of them appears to involve a hormone called vasopressin. In children as compared to adults, the mechanism and response to low blood pressure are different for reasons that are not clear. One possibility is the difference in the production and/or response to vasopressin. Vasopressin has become part of the treatment of children with low blood pressure in the setting of severe infection, when other treatment has failed, but its use is on the basis of animal and adult studies. The exact timing and dose is uncertain. In this research study, the patients will receive standard treatment for sepsis and septic shock, and the investigators will measure the blood levels of vasopressin and a related compound called copeptin (both are required to understand the mechanism of control involved). Blood will need to be taken from patients without any sepsis so as to be able to compare the values in health and in sickness. The patient groups the investigators have chosen for this are those children who will have blood taken anyway as part of their routine care. The aim of this study is to develop an understanding of the body's hormonal response (with respect to vasopressin) to severe infection in children. The long-term aim is to improve the care of critically ill children with severe infection by using the most appropriate dose of vasopressin at the most appropriate time.

Headache is a common symptom, and patients often seek medical attention at emergency departments due to headaches. The aim of the CoHead Study is to find out if it is possible by measuring copeptin, a marker of stress in the blood, to find out which patients have simple headaches and which patients have dangerous headaches that are the symptom of an underlying disease and need further investigation and treatment. Copeptin is a marker for physical stress and has been tested in patients with stroke, heart attack and pneumonia. In all these illnesses, the patients with the most serious forms had the highest levels of copeptin, while the ones with only mild presentation or no affection at all had the lowest levels of copeptin. The investigators expect to show the same in patients with headaches.
