We are the witnesses of a significant increase in chronic kidney diseases (CKD) occurrence. There is scarce literature evidence about functional integrity and natural adaptation of endocrine system axes in patients with different stages of always progressive CKD. Such a problem is growing with the beginning of renal replacement treatments (peritoneal and hemodialysis) or even with renal transplantation. The close monitoring of CKD patients by nephrologist and endocrinologist is mandatory because the natural adaptation of the endocrine system in CKD patients must be differed out of endocrine dysfunction, which has to be treated. Endocrine dysfunction management principles are mostly the same as for the patients with no CKD, except for close drug dose monitoring, especially in the circumstances with concomitant renal replacement treatment.
