OBJECTIVE
To assess whether serum concentrations of the anti-inflammatory cytokine growth differentiation factor 15 (GDF-15) differ in patients with highly active multiple sclerosis (MS) vs patients with stable MS and healthy controls (HCs).
METHODS
GDF-15 concentrations were measured by ELISA in serum and CSF in a cross-sectional cohort of patients with MS, patients with other inflammatory neurologic diseases (OIND), patients with noninflammatory neurologic diseases (NIND), and healthy controls (HC). Serum GDF-15 concentrations were measured in a longitudinally sampled cohort of clinically and radiologically well-characterized patients with MS and corresponding controls.
RESULTS
Cross-sectionally measured median serum GDF-15 concentrations were significantly higher in patients with OIND (n = 42) (600 pg/mL, interquartile range [IQR] = 320-907 pg/mL) compared with HCs (n = 29) (325 pg/mL, IQR = 275-419 pg/mL; = 0.0007), patients with NIND (n = 46) (304 pg/mL, IQR = 245-493 pg/mL; = 0.0002), or relapsing MS (n = 42) (356 pg/mL, IQR = 246-460 pg/mL; = 0.0002). CSF and serum concentrations of GDF-15 were correlated (r = 0.41, 95% CI = 0.25-0.56, < 0.0001). In a longitudinally sampled cohort of patients with MS (n = 48), deeply phenotyped with quantitative clinical and MRI assessments, mean GDF-15 concentrations were significantly higher in patients with a stable disease course (405 pg/mL, SD = 202) than in patients with intermittent MRI activity (333 pg/mL, SD = 116; = 0.02).
CONCLUSIONS
Serum GDF-15 concentrations are increased in patients with MS with a stable disease course. These data suggest that GDF-15 may serve as a biomarker for disease stability in MS.
目的
评估在活动期多发性硬化症（MS）患者与稳定期 MS 患者和健康对照者（HC）之间，抗炎细胞因子生长分化因子 15（GDF-15）的血清浓度是否存在差异。
方法
通过酶联免疫吸附试验（ELISA）在 MS 患者、其他炎症性神经疾病（OIND）患者、非炎症性神经疾病（NIND）患者和健康对照者（HC）的血清和脑脊液中测量 GDF-15 浓度。对具有明确临床和放射学特征的 MS 患者和相应对照者进行纵向采样队列，测量血清 GDF-15 浓度。
结果
OIND（n=42）患者的血清 GDF-15 浓度中位数（600 pg/ml，四分位距 [IQR]=320-907 pg/ml）显著高于 HC（n=29）（325 pg/ml，IQR=275-419 pg/ml；=0.0007）、NIND（n=46）（304 pg/ml，IQR=245-493 pg/ml；=0.0002）或复发型 MS（n=42）（356 pg/ml，IQR=246-460 pg/ml；=0.0002）患者。GDF-15 的脑脊液和血清浓度呈正相关（r=0.41，95%置信区间 [CI]=0.25-0.56，<0.0001）。在 MS 患者的纵向采样队列中（n=48），通过定量临床和 MRI 评估对其进行了深入表型分析，具有稳定疾病过程的患者的平均 GDF-15 浓度（405 pg/ml，标准差 [SD]=202）显著高于间歇性 MRI 活动的患者（333 pg/ml，SD=116；=0.02）。
结论
稳定疾病过程 MS 患者的血清 GDF-15 浓度升高。这些数据表明，GDF-15 可能作为 MS 疾病稳定的生物标志物。
