Baseline Copeptin value of ≥ 21.4 pmol/L identify patients with Nephrogenic Diabetes Insipidus with 100% Sensitivity and Specificity. 3 A second Copeptin measurement after fluid deprivation provides the following excellent results: References 1 Morgenthaler NG, Struck J, Jochberger S, Dü nser MW, Copeptin: clinical use of a new biomarker.
2015-02-27 · It is a clinically accepted fact that patients with ADPKD already have decreased urinary concentrating capacity at a young age , and that plasma osmolality is maintained within the normal range at the cost of higher plasma copeptin and AVP levels .
CONCLUSIONS: Regardless of cardiac surgical procedure and perioperative course, all patients had an early significant rise of copeptin concentrations, generally peaking at weaning from CBP or upon arrival in the intensive care unit. Conversely, during hypotonic saline infusion, plasma osmolality decreased and copeptin decreased to values in the very low normal range. Ref-21 Electroloyte disturbances are common in cardiovascular and renal diseases, including the most commonly seen hyponatremia, and the pathophysiology is complex and the diagnostic approach is challenging. Copeptin values according to normal plasma osmolality: Concentration range Intra-assay CV % Inter-assay CV % 2.0 – 4.0 pmol/L < 15.0 % < 18.0 % 4.0 – 15 pmol/L < 8.0 % < 10.0 % 15 – 50 pmol/l < 4.0 % < 5.0 % > 50 pmol/L < 3.0 % < 5.0 % Out of range samples (> 500 pmol/L) < 4.0 % < 6.0 % The normal range of plasma copeptin levels is from 1.0 to 13.8 pmol/l with higher median levels in men than in women according to two large physiological studies in healthy volunteers [26, 43]. The difference in gender is poorly understood, also because no significant changes during the menstrual cycle were observed [ 44 ]. Patients with CDI had lower copeptin levels than patients with DH or SO (both P < 0.01) or those with NDI. Copeptin identified CDI with an AUC of 0.99 (95% CI 0.97–1.00), and a cut-off value ≤ 4.4pmol/L showed a sensitivity of 100% and a specificity of 99% to predict CDI. Indeed, recent studies have found promise in its use in managing sepsis as copeptin levels were found to distinguish normal controls from septic patients, and septic patients from septic shock patients [44].

Jun 6, 2019 Might blood testing for copeptin offer an easier diagnostic method than the indirect water deprivation test—the current reference standard—may be more with the copeptin levels masked.1 The researchers reported that
May 4, 2018 As such, we chose to use copeptin as a surrogate marker for AVP. Serum potassium and magnesium levels were maintained within the normal range. The three control patients had a mean CSF copeptin level of only 253&nb The copeptin levels were estimated using Human C- Reactive protein ELISA Kit, observed between Copeptin levels of patients with normal Body Mass Index Sep 16, 2014 In a study of healthy controls versus hospitalized patients with increasing levels of stress, copeptin was found to be a more subtle marker of stress Mar 18, 2015 In cardiovascular shock, copeptin levels are elevated. As such, copeptin is a potential biomarker for MI diagnosis and predictor for HF mortality AVP and copeptin values were correlated with plasma osmolality using an in- house normogram allowing comparison of AVP response to a reference population Jun 16, 2016 copeptin levels, a surrogate marker of arginine vasopressin, have been tion, while remaining in the physiologically normal range, may have Among patients with normal copeptin concentration preoperatively and the postoperative copeptin concentrations decreased to normal values within 3-to-4 Copeptin: A new peptide in clinical measurement .
Copeptin is a novel, independent prognostic marker improving currently used risk stratification of stroke patients. Ann Neurol 2009;66:799-808.
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. 33 Both trials reported higher median plasma copeptin levels in men than in women, whereas no correlation with age was shown. 13, 33 The difference in gender is poorly understood. Normal values and physiological response of plasma copeptin in healthy volunteers The reference range for copeptin was first defined in a study with 359 healthy volunteers. This study showed the broad range of copeptin values.
2010-05-26 · In healthy volunteers and under rest, normal copeptin levels have 4.0-4.4 pmol/l as range with only 5% of values lying outside this range . Statistical analysis. A logarithmic transformation was performed to obtain a normal distribution for skewed variables (i.e. copeptin concentrations). 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.

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). 2010-05-26 · In healthy volunteers and under rest, normal copeptin levels have 4.0-4.4 pmol/l as range with only 5% of values lying outside this range .

Data from the first study with healthy volunteers, which was carried out without prior fluid control or fasting, indicated a median copeptin plasma concentration of 4.2 pmol.L −1 (range, 1–13.8 pmol·L −1) 46. The copeptin test measures the amount of copeptin in the blood.
Indeed, recent studies have found promise in its use in managing sepsis as copeptin levels were found to distinguish normal controls from septic patients, and septic patients from septic shock patients [44]. It may also hold promise as a cardiology biomarker in conjunction with troponin for acute myocardial infarction rule out [45,46]. Patients were analyzed as a whole cohort (n = 20) and in a restricted "normal cohort" consisting of patients with normal preoperative copeptin concentration (<10 pmol/L) and perioperative uneventful course (n = 11). In the whole cohort, preoperative copeptin concentration was 7.0 pmol/L (interquartile range: 3.1-11 pmol/L). When the prespecified morning copeptin cutoff level of less than 2.6 pmol per liter after overnight water deprivation was used to identify patients with complete central diabetes insipidus, 5 the Copeptin was still above normal at day 7 while the concentration of other inflammatory markers approached normal values at that time. The potential biomarkers such as copeptin have to be always estimated in the context of a careful clinical assessment.
