Changes in Sepsis Biomarkers after Immunosuppressant Administration in Transplant Patients.

Sepsis biomarkers change continuously during the postoperative period. We aimed to demonstrate the influence of immunosuppressants after transplantation (Tx) on presepsin, procalcitonin, CRP, white blood cells, and IL-6. A group of 140 patients after major surgery (86 non-Tx, 54 Tx) without any signs of sepsis or infectious complications was followed for 7 days.

Biological variation of intact fibroblast growth factor 23 measured on a fully automated chemiluminescent platform.

Background: Fibroblast growth factor 23 (FGF23), a potent regulator of phosphate and vitamin D metabolism, is a new biomarker of kidney, bone and cardiovascular disorders. The aim of this study was to assess the biological variation of intact fibroblast growth factor 23 (iFGF23).

Methods: The within-subject (CV) and between-subject (CV) biological variations were assessed in 14 healthy volunteers in a six-week protocol (seven samples).
