BACKGROUND
In Wilson's disease (WD), early neurological deterioration after treatment initiation is associated with poor outcomes; however, data on this phenomenon are limited. Our study analysed the frequency and risk factors of early neurological deterioration in WD.
METHODS
Early neurological deterioration, within 6 months from diagnosis, was defined based on the Unified Wilson's Disease Rating Scale (UWDRS): any increase in part II or an increase of ≥ 4 in part III. In total, 61 newly diagnosed WD patients were included. UWDRS scores, brain magnetic resonance imaging (MRI) scores, copper metabolism parameters, treatment type and serum neuro-filament light chain (sNfL) concentrations at diagnosis were analysed as potential risk factors of early deterioration.
RESULTS
Early neurological deterioration was observed in 16.3% of all WD patients; all cases of worsening occurred in the neurological phenotype (27.7%). Higher scores were seen in those who deteriorated compared with those who did not for UWDRS part II (4.3 ± 5.0 vs 2.0 ± 5.9; p < 0.05), UWDRS part III (21.5 ± 14.1 vs 9.3 ± 16.4; p < 0.01) and MRI-assessed chronic damage (3.2 ± 1.6 vs 1.4 ± 2.2; p = 0.006); all these variables indicated the initial severity of neurological disease. Pre-treatment sNfL concentrations were significantly higher in patients who deteriorated compared with those who did not (33.2 ± 23.5 vs 27.6 ± 62.7 pg/mL; p < 0.01). In univariate logistic regression amongst all patients, chronic damage MRI scores, UWDRS part III scores and sNfL concentrations predicated early deterioration. In the neurological WD, only sNFL were a significant predictor. In bivariate logistic regression amongst all patients, sNfL remained the only significant predictor of deterioration when corrected for MRI scores.
CONCLUSION
sNfL concentrations are a promising biomarker of the risk of early neurological deterioration in WD.
背景
在威尔逊病（WD）中，治疗开始后早期神经恶化与不良预后相关；然而，关于这一现象的数据有限。我们的研究分析了 WD 中早期神经恶化的频率和危险因素。
方法
根据统一威尔逊病评定量表（UWDRS），将诊断后 6 个月内的神经恶化定义为：第 II 部分任何增加或第 III 部分增加≥4。共纳入 61 例新诊断的 WD 患者。分析 UWDRS 评分、脑磁共振成像（MRI）评分、铜代谢参数、治疗类型和诊断时血清神经丝轻链（sNfL）浓度作为早期恶化的潜在危险因素。
结果
所有 WD 患者中有 16.3%出现早期神经恶化；所有恶化病例均发生在神经表型（27.7%）。与未恶化者相比，恶化者 UWDRS 第 II 部分（4.3±5.0 与 2.0±5.9；p<0.05）、UWDRS 第 III 部分（21.5±14.1 与 9.3±16.4；p<0.01）和 MRI 评估的慢性损伤评分（3.2±1.6 与 1.4±2.2；p=0.006）均较高，所有这些变量均表明神经疾病的初始严重程度。与未恶化者相比，恶化者治疗前 sNfL 浓度显著升高（33.2±23.5 与 27.6±62.7 pg/mL；p<0.01）。在所有患者的单变量逻辑回归中，MRI 评分、UWDRS 第 III 部分评分和 sNfL 浓度预测早期恶化。在神经 WD 中，只有 sNFL 是早期恶化的显著预测因子。在所有患者的双变量逻辑回归中，当校正 MRI 评分时，sNfL 仍然是恶化的唯一显著预测因子。
结论
sNfL 浓度是 WD 早期神经恶化风险的一个有前途的生物标志物。
