Active clinical trials for "Diabetes Insipidus"

The are 2 principal goals in this study: To measure plasma copeptin levels in healthy subjects and to correlate them with plasma AVP concentrations and urine osmolalities in iso-, hypo-, and hyperosmolar states. To measure plasma copeptin concentrations in patients with chronic renal failure under the same conditions described above, in order to characterize the impact of renal function on circulating copeptin levels in correlation to plasma AVP and urine osmolality.

Sodium imbalance is common and an adverse prognostic factor in hospitalized patients. However, identifying the causes of sodium imbalance is challenging in clinical practice. Levels of antidiuretic hormone (ADH) are elevated in patients with stroke correlating with disease severity and stress level; however, its measurement is cumbersome. ADH is derived from a larger precursor peptide along with Copeptin, which is a more stable peptide directly mirroring the production of ADH. Copeptin can be assayed readily in plasma. Early prognostic factors to predict in-hospital mortality and medium/long-term outcome in critically ill neurological patients, are helpful to guide and tailor early decisions on treatment, discharge from the intensive care unit and application of interventions to prevent deterioration of neurological functions. We hypothesize that copeptin will improve the diagnostic accuracy to diagnose sodium imbalances as compared to routinely used markers Furthermore, we hypothesize that Copeptin will be a reliable prognostic tool, dependent or independent of sodium imbalance, to predict short-term (i.e. in-hospital) and medium-term (i.e. 3 months) clinical outcome in stroke patients.

This study evaluates the relevance of Copeptin in children with congenital heart disease undergoing cardiac surgery with the need of cardiopulmonary bypass. Three blood samples are taken of each patient. The first and second sample are collected in the operation room before and after the procedure and the third sample on the first postoperative day at the intensive care unit.

Water imbalance and consecutive electrolyte disturbances are common in the postoperative course of neurosurgical patients after pituitary surgery. Diabetes insipidus (DI) may complicate the postoperative course in as many as 30% of patients. Early and accurate diagnosis of water and electrolyte disturbances postoperatively is important for an adequate fluid and drug administration. However, identifying the causes is challenging/ ambiguous in clinical practice. Levels of antidiuretic hormone (ADH) might contribute to a straightforward diagnosis, though, its measurement is cumbersome. ADH is derived from a larger precursor peptide along with copeptin, which is a more stable peptide directly mirroring the production of ADH. Copeptin can be assayed readily in plasma. Aim: To investigate whether copeptin can accurately diagnose postoperative disturbances of water homeostasis (i.e. Diabetes insipidus and SIADH) in a cohort of patients undergoing intracranial tumor surgery.

Kinetics of Copeptin in response to osmotic alterations in healthy volunteers

The aim of the PsyCo Study is to determine whether psychological Stress has an influence on copeptin levels.

The purpose of this study is to determine whether copeptin levels are affected by food intake.

To investigate whether copeptin levels increase upon a psychological stress (i.e. written examination) and whether copeptin levels measured immediately before the written examination predict success of the examination.

The main objective of our study is to evaluate the diagnostic value of copeptin testing in association with troponin HS testing during pre-hospital care (ambulance care) in the treatment of patients whose pattern of use is the occurrence chest pain suggestive of ACS but not ST+.

We study the hypothesis that combination of Proteine S100 beta and Copeptin within normal ranges can rule out seizure recurrences and severe outcome, and allow early discharge from the emergency department
