Copeptin/UNa ratio may be used as a potential biomarker of Syndrome of Inappropriate Antidiuretic Hormone (SIADH in patients with tick-borne encephalitis (TBE) . Copeptin concentration is significantly higher in patients with TBE than in viral meningitis of other origin, especially in patients aged 18-34 and >49 years old.

Copeptin frigjøres fra nevrohypofysen i ekvimolare mengder med ADH, og kan derfor brukes som en surrogat markør for ADH. Analytisk er den mere stabil, og enklere å analysere enn ADH. ADH fases ut fra 01.10.19, dvs ADH-prøver som mottas etter dette vil bli analysert for copeptin. Copeptin, the C-terminal portion of provasopressin, is a 39-amino acid glycopeptide of unknown function . Copeptin may have a role during the intracellular processing of provasopressin, possibly contributing to correct structural formation of the precursor, which leads to efficient proteolytic maturation .

In this study, researchers studied 141 patients with hypotonic polyuria; ultimately, 58% received diagnoses of primary polydipsia, and 42% received diagnoses of partial or complete central diabetes insipidus. Copeptin is a peptide, which is cleaved from the neurohypophysial hormone prepro-vasopressin and secreted in the blood during procession to vasopressin (Keller et al., 2010). It is released during stress and shows a rapid increasing kinetic.

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.

Background: Copeptin, the C-terminal moiety of provasopressin, is cosecreted with vasopressin. Copeptin may be a useful parameter to characterize disorders of water homeostasis and can be readily measured in plasma or serum. However, it is unknown to date how circulating copeptin and vasopressin levels correlate at different plasma osmolalites. To overcome these obstacles, copeptin, the C-terminal fragment stemming from the ADH precursor, has been increasingly used as a stable clinical measure for ADH. Furthermore, copeptin has been recognized as a biomarker of insulin resistance in obesity. Copeptin, a 39-amino acid glycopeptide, is the C-terminal part of the prohormone of arginine vasopressin (AVP) or antidiuretic hormone (ADH).

Copeptin (also known as CT-proAVP) is a 39-amino acid-long peptide derived from the C-terminus of pre-pro-hormone of arginine vasopressin, neurophysin II and copeptin. Arginine vasopressin (AVP), also known as the antidiuretic hormone (ADH), is involved in multiple cardiovascular and renal pathways and abnormal level of AVP are associated with various diseases.
