Oxidative Stress and Vitamin D as Predictors in Multiple Sclerosis.

Multiple Sclerosis (MS) is a multifactorial demyelinating diseases that affect mostly the young and active people. Here, is crucial to identify new strategies in order to slow down the diseases progression and maintain a good functional outcome. Our hypothesis was that the interconnection between anti-oxidant molecules and anti-inflammatory or neuroprotective molecules can act as predictors of diseases progression. In the study were included 36 patients with MS. Inclusion criteria were the following: patients over 18 years old were divided in three groups, 16 relapsing-remitting MS (RRMS) group, 10 secondary progressive MS (SPMS) group and 10 healthy control group. We showed that the vitamin D sufficiency did not improve de EDSS score in the later stage of diseases. Also, we showed that in the early stage (RRMS) the vitamin D status can significantly improve the EDSS and IADL score and may slow down the diseases progression. started with the early stage of diseases (RRMS) we found that catalase activity, an enzyme that act as anti-oxidant, is significantly decreased compare with healthy people, and can be associated with a low level of vitamin D. we concluded that a pro-oxidative and anti-oxidative balance is an important player in the multifactorial mechanism of MS diseases progression and additional prospective studies are needed to determine optimal vitamin D levels that lead to clinical and immunological benefits for patients with MS. Long-term follow-up studies using high-dose vitamin D supplementation are needed to confirm the preliminary results of the studies.
