2016-03-01 · The median copeptin plasma concentration was 4.2 pmol/L with a range between 1 and 13.8 pmol/L . Similarly, copeptin concentrations in healthy volunteers of a population of 5000 individuals ranged between 1 and 13 pmol/L (upper 97.5 percentile) with median values <5 pmol/L [12] . In the first study including 359 subjects, plasma copeptin levels ranged from 1.0 to 13.8 pmol/L with a median concentration of 4.2 pmol/L. 13 The second evaluation with over 700 randomly selected volunteers reported comparable results with plasma copeptin levels ranging from 1.0 to 13.0 pmol/L.

The difference in gender is poorly understood, also because no significant changes during the menstrual cycle were observed [ 44 ]. Copeptin measurement has been shown to be useful in various clinical indications, including the diagnosis of diabetes insipidus and the monitoring of sepsis and cardiovascular diseases.

2017-06-13 · Copeptin is derived from the cleavage of the precursor of arginine vasopressin (AVP), produced in an equimolar ratio in hypothalamus and processed during axonal transport AVP is an unstable peptide and has a short half-life of 5–20 min. Unlike AVP, copeptin is a stable molecule and can easily be measured. Recent evidence suggest that increased copeptin levels have been associated with worse They found that copeptin was an independent predictor of APE-related mortality .

Copeptin normal range

Copeptin is a 39-amino acid glycopeptide derived from preprovasopressin and it is cosecreted in the bloodstream with vasopressin in an equimolar ratio in response to osmotic and hemodynamic changes. It is slowly degraded and in healthy individuals normal values of copeptin range between 1.70 and 11.25 pmol/L . Copeptin is the C terminal peptide of proAVP and is co-secreted on an equimolar basis with AVP from the posterior pituitary. Arginine vasopressin (AVP), also known as antidiuretic hormone (ADH), is a hypothalamic polypeptide that is transported along the axons of the synthesizing neurons into the posterior pituitary gland. Copeptin is the stable surrogate marker of vasopressin (VP), which is released in response to elevated plasma osmolality or low blood pressure. Elevated plasma copeptin levels are associated with higher risk of insulin resistance-related disorders, such as type 2 diabetes (T2DM), metabolic syndrome (MS), and cardiovascular disease, and experimental reduction of circulating VP levels is shown 2019-05-31 · Before the start of the exercise bout, copeptin levels were 4.5 (SD: 2.7) pmol/l and 4.3 (SD: 2.0) pmol/l in the placebo and anakinra group, respectively. In both groups, copeptin levels rose significantly by 2.5-fold upon exercise and peaked at the end of the exercise period (60 minutes, p<0.001).

A A A During arginine stimulation, clinical and laboratory parameters remained generally stable and in the normal range. Seven patients (all with diabetes insipidus) had mild hypernatraemia (range 146–149 mmol/L) at the end of the test. Overall, the test burden was low, although nausea was a frequent symptom during arginine stimulation. As a Control Group, 30 healthy individuals with normal physical examination results were included. In terms of blood copeptin levels, the result was 0.48 ± 0.27 ng/ml for the Control Group, 1.03 ± 0.56 ng/ml for Group 1, and 0.50 ± 0.32 ng/ml for Group 2. Moreover, copeptin has been suggested as a unifying factor of the main components of the metabolic syndrome [17] and elevated levels of copeptin strongly predict the subsequent development of diabetes mellitus . The[18] potential connection between copeptin or AVP levels and cognitive impairment has not been studiedpreviously .

Copeptin was raised in patients with death or HF compared with event-free survivors . Copeptin is a novel, independent prognostic marker improving currently used risk stratification of stroke patients. Ann Neurol 2009;66:799-808. Distribution of copeptin is shown in Supplementary Figure S1, with a median value of 6.4 (3.8 to 11.0) pmol/l, and higher values in males than females. Subjects with higher copeptin had higher systolic and diastolic blood pressure, a higher body mass index as well as higher total kidney volume (TKV) and lower eGFR. 19 male and female subjects, aged 18–53 years (mean 25.8 years), participated in the study.
