Matrix Metalloproteinase-9 and Inflammation in Different Types of Multiple Sclerosis

Different clinical courses of multiple sclerosis, heterogeneity of its clinical implications, different effect of immunomodulatory therapy for the same clinical forms implies various pathogenetic mechanisms of central nervous system damage at this disease. Applicability of immunological and biochemical markers for the estimation of immunocorrecting and anti-inflammatory therapy efficacy is important. This research aims at improvement of pathological process stages diagnostics at multiple sclerosis and further therapy optimization depending on the activity of the inflammatory process. In the article matrix metalloproteinase-9 rate was assessed in 135 patients with multiple sclerosis of different course types and at different activity stages of the pathological process. The highest matrix metalloproteinase-9 rates were in patients with relapsing-remitting type at the stage of exacerbation, with the lowest rate being in patients with primary-progressive multiple sclerosis. Determination of matrix metalloproteinase-9 rate allows to assess the degree of inflammatory process expression and to monitor the efficacy of multiple sclerosis treatment
