Objectives: To explore possible link between intradialytic hypotension (IDH) with serum fibroblast growth factor 23 (FGF23) and serum soluble klotho (sKl) in maintenance hemodialysis (MHD) patients in a single dialysis center. Materials and Methods: Cross-sectional data were collected from MHD patients. Intradialytic blood pressure was recorded continuously in a 1-month period. According to the dialysis records, MHD patients were divided into IDH group and non-IDH group. Fast sera of the MHD patients were obtained for FGF23 and sKl assay at the end of IDH record month, and other routing laboratory results were analyzed statistically for comparison between the two groups. Results: A total of eighty MHD patients with complete laboratory data were enrolled into the study. The occurrence rate of IDH was 77.5%. The significant differences in serum ferritin (P = 0.046), serum triglyceride (P = 0.045), parathyroid hormone (P = 0.042), calcium-phosphorus product (P = 0.047), and serum FGF23 (P < 0.001) were found between the two groups, but the difference in sKl between the two groups was marginal (P = 0.747). Furthermore, the serum FGF23 was positively correlated with the occurrence of IDH (r = 0.807, P< 0.001). Conclusions: The present study indicated a positive correlation between serum FGF23 and IDH in MHD patients, which suggested the FGF23 could be a potential biomarker for incidence of IDH in the hemodialysis population.
