[Correlation of fibroblast growth factor 23 with 
adverse prognosis of chronic kidney disease and
therapy strategy].

Fibroblast growth factor 23 (FGF23) is a hormone secreted by the bone. It is not only involved in the pathophysiological process of chronic kidney disease (CKD), but also associated with the poor prognosis. In patients with CKD, serum FGF23 levels are elevated in early phase. The increased FGF23 levels gradually lead to myocardial hypertrophy, inflammatory, vascular calcification, and low level of vitamin D, which contribute to the progress of CKD, cardiovascular complications and even death. Presently, there are several ways to reduce FGF23 levels, including decrease of intake and block of phosphorus absorption, supplement of FGF23 antibody and pseudo calcium or renal transplantation.
