Abstract

Objectives: Substantial evidence supports the hypothesis that oxygen free radicals are involved in various neurodegenerative disorders. To assess the presence of oxidative stress in Creutzfeldt-Jakob disease (CJD) we examined the concentrations of malondialdehyde (MDA) as an established marker of lipid peroxidation.

Material and methods: MDA was quantified by high performance liquid chromatography (HPLC) in cerebrospinal fluid (CSF; n=12) and in serum (n=11) samples of CJD patients and healthy controls (n = 15).

Results: Mean values in healthy controls: 2.56 nmol/ml +/- 0.46 (CSF) and 1.94 nmol/ ml +/- 0.67 (serum); mean values in CJD patients: 2.64 nmol/ml +/- 0.67 (CSF) and 1.68 nmol/ml +/- 0.79 (serum). No significant (P>0.05) difference between CJD patients and controls was observed.

Conclusions: The results indicated that the CSF and serum of CJD patients showed no higher endogenous levels of MDA as compared to normal healthy controls. These findings provide no evidence for an additional role of oxidative stress in the pathogenetic mechanism underlying CJD neurodegeneration.
