[Evaluation of oxidoreductive potential of patients with neuroborreliosis].

Aim: The purpose of the study was to evaluate parameters of oxidoreductive system in serum and cerebrospinal fluid (CSF) of patients with neuroborreliosis.
Material and Methods: The cases were 25 patients aged 21 to 64 (x = 42.3) hospitalized with diagnosis of neuroborreliosis. Activity of superoxide dismutase (Cu, Zn-SOD), glutathione reductase (GSSG-R), glutathione peroxidase (GSH-Px) and concentration of sulphydryl groups (-SH) and malondialdehyde (MDA) in serum and CSF were tested. The control group consisted of 10 patients with diagnosis of discopathy. An examination was performed twice: before and after treatment.
Results: Results of the study showed lack of stability in an oxidoreductive system during neuroborreliosis both in serum and in CSF. In CSF activity of SOD was increased while activity of GSH-Px and GSSG-R were decreased. Also concentration of -SH and lipid peroxidation products measured as MDA were increased. The increase of SOD, GSH-Px, GSSG-R activity and concentration of -SH and MDA in serum were detected.
Conclusions: Disorders of an oxidoreductive system in CSF and serum during neuroborreliosis were observed. These changes persisted despite treatment and normalization of inflammatory CSF markers.
