Abstract
INTRODUCTION
Multiple sclerosis (MS) is a chronic, demyelinating disease of the central nervous system. Its clinical courses are clinically isolated syndrome (CIS), relapsing remitting (RRMS), secondary progressive (SPMS), and primary progressive (PPMS). The differentiation of MS types is crucial for adequate treatment.
OBJECTIVES
To evaluate antioxidant parameters of MS patients' serum according to MS type.
MATERIALS AND METHODS
The study included 84 patients diagnosed with MS. The study group was divided into three subgroups corresponding to MS courses RRMS, SPMS, and PPMS. Sulfhydryl groups (SH), ceruloplasmin (CER), and superoxide dismutase (SOD) and its isoforms were identified in study participants' sera.
RESULTS
CuZnSOD levels were significantly higher in SPMS patients than in PPMS patients, but there was no difference between SMPS and treatment-naive PPMS patients. MnSOD activity was significantly lower in SPMS patients than in PPMS patients. Our results show that SH levels were decreased in SPMS patients compared with RRMS patients, but this difference was significant only for male participants. SH concentration was reversely correlated with age, BMI, disease duration, EDSS, and in smoking patients with pack-years. CER serum levels waere elevated in SPMS patients compared with RRMS patients, but this difference was significant only for male participants. Our results show correlation between CER and EDSS levels.
CONCLUSION
Oxidative stress plays a limited role in all disease stages, particularly in smokers as a confounding factor.
