Endocan and Copeptin Serum Levels in Preterm Neonates With Respiratory Distress Syndrome

Preterm birth continues to be one of the significant challenges in perinatal medicine because of its high incidence of morbidities and mortalities. Its burden on the infant, the family, healthcare systems, and society is enormous.

Endocan is implicated in the recruitment of circulating lymphocytes to inflammatory sites and leukocyte adhesion and activation. Endocan also inhibits leukocyte-endothelial cell adhesion and reduces the excessive leukocyte recruitment into the lungs.

Copeptin, also known as the arginine vasopressin (AVP) associated glycopeptides. AVP is a vasoactive neurohypophysial hormone. It is one of the primary hormones of the hypothalamic-pituitary-adrenal axis, and its primary function is to regulate water and maintain electrolyte homeostasis. The primary stimulus for AVP release is hyperosmolarity.
