The use and interpretation of diagnostic cerebrospinal fluid (CSF) biomarkers for neurodegenerative disorders, such as Dementia with Lewy bodies (DLB), represent a clinical challenge. According to the literature, the composition of CSF in DLB patients varies. Some patients present with reduced levels of amyloid, others with full Alzheimer Disease CSF profile (both reduced amyloid and increased phospho-tau) and some with a normal profile. Some patients may present with abnormal levels of a-synuclein. Continuous efforts will be required to establish useful CSF biomarkers for the early diagnosis of DLB. Given the heterogeneity of methods and results between studies, further validation is fundamental before conclusions can be drawn.
用于神经退行性疾病(如路易体痴呆症,DLB)的诊断性脑脊液(CSF)生物标志物的使用和解释是一个临床挑战。根据文献,DLB 患者的 CSF 组成不同。一些患者的淀粉样蛋白水平降低,另一些患者则具有完整的阿尔茨海默病 CSF 特征(淀粉样蛋白和磷酸化 tau 均降低),还有一些患者的 CSF 特征正常。一些患者可能表现出异常水平的 a-突触核蛋白。为了建立用于 DLB 早期诊断的有用 CSF 生物标志物,需要不断努力。鉴于研究之间方法和结果的异质性,在得出结论之前,进一步验证是至关重要的。
