This work aimed to study whether fibroblast growth factor 23 (FGF23) is predictive for incident posttransplant diabetes mellitus (PTDM) in kidney transplant recipients (KTRs).
We repeatedly analyzed plasma C-terminal FGF23 concentrations in 170 KTRs enrolled in the TransplantLines Biobank and Cohort Study. Associations of time-updated plasma FGF23 with incident PTDM were studied by Cox regression.
A total of 170 KTRs (46% female, aged 54.4 ± 12.4 years) with 540 FGF23 measurements were included. Plasma FGF23 concentrations at transplantation were 31.1 (0.76-2576) pmol/L. During a follow-up of 24 (12-24) months, 38 patients developed PTDM. The highest FGF23 tertile (compared to the lowest) was associated with an increased risk for PTDM (fully adjusted hazard ratio 20.9; 95% CI, 3.4-130.0; < .001).
In KTRs without diabetes at baseline, the highest tertile of FGF23, compared to the lowest, is predictive for development of PTDM.
本研究旨在探讨成纤维细胞生长因子23（FGF23）是否可预测肾移植受者（KTRs）发生移植后糖尿病（PTDM）。
我们对纳入移植生物样本库和队列研究的170例KTRs的血浆C末端FGF23浓度进行了重复分析。通过Cox回归研究随时间变化的血浆FGF23与新发PTDM之间的关联。
共纳入170例KTRs（46%为女性，年龄54.4±12.4岁），进行了540次FGF23测量。移植时血浆FGF23浓度为31.1（0.76 - 2576）pmol/L。在24（12 - 24）个月的随访期间，38例患者发生了PTDM。FGF23最高三分位数（与最低三分位数相比）与PTDM风险增加相关（完全调整后的风险比为20.9；95%可信区间，3.4 - 130.0；P <.001）。
在基线无糖尿病的KTRs中，FGF23最高三分位数与最低三分位数相比，可预测PTDM的发生。
