Fluids and Barriers of the CNS dergisinde yayınlanan bir makale, huzursuz bacak sendromunda (Willis-Ekbom Hastalığı) kontrol gruplarına göre serebrospinal sıvıda bazı proteinlerde değişimlerin olabileceği gösterilmiş. Huzursuz bacak sendromunun erken döneminde, kontrol grubuna göre, serebrospinal sıvıdaki 4 belirteç proteinde (Sistatin C, Lipokalin-tip Prostaglandin D2 Sentaz, Vitamin D bağlayan Protein ve β-Hemoglobin) artış saptanırken 2 belirteç proteinde (Apolipoprotein A1 ve α-1-asid Glikoprotein) düşüş olduğu saptanmış.

Proteomic analysis of the cerebrospinal fluid of patients with restless legs syndrome/Willis-Ekbom disease
Restless Legs Syndrome/Willis-Ekbom Disease (RLS/WED) is a sensorimotor disorder that causes patients to experience overwhelming and distressing sensations in the legs compelling the patient to move their legs to provide relief. The purpose of this study was to determine if biomarkers in the cerebrospinal fluid can distinguish RLS/WED patients from neurological controls.
We obtained CSF samples by lumbar puncture from 5 early-onset RLS/WED patients and 5 controls. We performed 2-dimensional difference in-gel electrophoresis (2D-DIGE). Proteins that were significantly altered were identified by Student’s t-test. Protein spots that were differentially expressed (p <= 0.05, Av. Ratio >= 2.0) between RLS/WED and control CSF samples were identified using MALDI-TOF-MS. Statistical analyses of the validation immunoblot assays were performed using Student’s t-test.
In this discovery study we identified 6 candidate CSF protein markers for early-onset RLS/WED. Four proteins (Cystatin C, Lipocalin-type Prostaglandin D2 Synthase, Vitamin D binding Protein, and beta-Hemoglobin) were increased and 2 proteins (Apolipoprotein A1 and alpha-1-acid Glycoprotein) were decreased in RLS/WED patients.
Our results reveal a protein profile in the RLS/WED CSF that is consistent with clinical findings of disruptive sleep, cardiovascular dysfunction and painful symptoms. Moreover, protein profiles are consistent with neuropathological findings of activation of hypoxia inducible factor (HIF) pathways and alterations in dopaminergic systems. These data indicate the CSF of RLS/WED patients may provide information relevant to biological basis for RLS/WED, treatment strategies and potential new treatment targets.
