血清FGF23、Klotho蛋白与维持性血液透析患者心脏瓣膜钙化的相关性

Study on the correlation between serum FGF23, Klotho protein levels and cardiac valve calcification in maintenance hemodialysis patients

    摘要
  • 摘要:
    目的 探讨血清成纤维细胞生长因子23（fibroblast growth factor-23，FGF23）、Klotho蛋白水平与维持性血液透析(maintenance hemodialysis，MHD）患者心脏瓣膜钙化(cardiac valve calcification, CVC)的相关性。
    方法 选取2022年1月至2023年1月期间复旦大学附属金山医院血液净化中心MHD患者169例，采用心脏超声检查患者CVC情况。
    结果 169例MHD患者中CVC者共111例，占65.68%。与非CVC组相比，CVC组FGF23、β2微球蛋白、B型脑钠肽（brain natriuretic peptide，BNP）水平、年龄、男性占比显著高，Klotho、透前肌酐、血红蛋白、血浆白蛋白、iPTH水平显著低（均P＜0.05）。Pearson/Spearman相关系数分析提示FGF23、年龄、男性、β2微球蛋白、BNP与CVC正相关（r＝0.20、0.41、0.15、0.28、0.12），Klotho、透前肌酐、血红蛋白、血浆白蛋白、iPTH与CVC负相关（r＝-0.16、-0.17、-0.16、-0.17、-0.16）。非条件二元logistic回归分析显示FGF23、Klotho、年龄、β2微球蛋白是MHD患者CVC的独立影响因素（P＜0.05）。
    结论 MHD患者易发生CVC，血清FGF23水平与CVC正相关，Klotho蛋白水平与CVC负相关，FGF23、Klotho、年龄、β2微球蛋白是MHD患者CVC的独立影响因素。

     

    Abstract:
    Objective To explore the correlation between serum fibroblast growth factor-23 (FGF23), Klotho protein levels and cardiac valve calcification (CVC) in patients with maintenance hemodialysis (MHD).
    Methods A total of 169 MHD patients in the Blood Purification Center of Jinshan Hospital, Fudan University from January 2022 to January 2023 were selected. The patients' CVC status was examined by color Doppler echocardiography.
    Results There were 111 CVC cases, accounting for 65.68%. Compared with the non-CVC group, the CVC group had significantly higher levels of FGF23, β2-microglobulin, brain natriuretic peptide (BNP), age, and the proportion of male, while significantly lower levels of Klotho, predialysis creatinine, hemoglobin, plasma albumin and iPTH (P < 0.05). Pearson/Spearman correlation coefficient analysis showed that FGF23, age, β2-microglobulin and BNP were significantly positively correlated with CVC (r＝0.20, 0.41, 0.15, 0.28, 0.12), while Klotho, predialysis creatinine, hemoglobin, plasma albumin and iPTH were significantly negatively correlated with CVC (r＝-0.16, -0.17, -0.16, -0.17, -0.16). Unconditioned binary logistic regression analysis showed that FGF23, Klotho, age and β2-microglobulin were independent risk factors for CVC in MHD patients.
    Conclusions MHD patients are prone to CVC. Serum FGF23 protein level is significantly positively correlated with CVC, while Klotho protein level is significantly negatively correlated with CVC. FGF23, Klotho, age and β2-microglobulin are independent risk factors for CVC in MHD patients.
