Effects of the whole-body cryotherapy on a total antioxidative status and activities of some antioxidative enzymes in blood of patients with multiple sclerosis-preliminary study.

OBJECTIVE There is evidence that multiple sclerosis (MS) is not only characterized by immune mediated inflammatory reactions but also by neurodegenerative processes. Neutralization of oxidative stress and excitotoxicity, might represent a therapeutic approach to provide neuroprotection in MS. The purpose of this study was to compare changes in total antioxidative status and activities of chosen antioxidative enzymes, such as: SOD, CAT in erythrocytes of patients with MS before and after using WBCT with control group. MATERIALS AND METHODS 32 patients with multiple sclerosis (ICD10-G35) and 20 healthy subjects were recruited for the study. The examined MS group (n=16) was treated with a series of 10 daily exposures in a cryogenic chamber (2-3 min, from -120 degrees C to -110 degrees C) and program of exercises. The control MS group (n=16) had only exercises. Plasma TAS as well as SOD and CAT activities in erythrocytes were measured. RESULTS The level of TAS in MS patients was distinctly reduced compared to healthy subjects. After two weeks of WBCT treatment an increase of TAS in the whole examined group (p>0.01) were observed in relation to control MS group. There was not increase of CuZnSOD and CAT activities. CONCLUSION Our results suggest positive antioxidant effects of WBCT as a short-term adjuvant treatment for patients suffered due to MS.
