Multiple sclerosis (MS) is a chronic disease of the central nervous system, it is the main cause of “non-injury” disability in the young adults’ population. As shown in clinical studies, the disease course may be changed by so-called disease modifying drugs (DMD): beta-interferons (IFN-β-1a and IFN-β-1b) as well as glatiramer acetate (GA). The purpose of this work was to analyse the course of the disease and changes in magnetic resonance imaging (MRI) scans of the brain and of the cervical spinal cord in patients with relapsing-remitting multiple sclerosis (RRMS) during a 2-year DMD therapy. The following therapies were evaluated: IFN-β-1b (250 μg), IFN-β-1a (44 mg), IFN-β-1a (30 μg) and GA (20 mg). The study duration was 24 months. The study was performed in 118 patients with RRMS. Mean patient age was 29.0±8.6 (18-50) years with disease duration of 3.4±1.6 years. The patients were treated as follows: 20 patients received IFN-β-1a (30 μg), 40 – IFN-β-1b (250 μg), 33 – IFN-β-1a (44 μg) and 25 – GA (20 mg). The female patients predominated in the study group – 66.1%. EDSS score before treatment was 2.3±0.9. The annualised relapse rate (ARR) for the entire study group was 0.82. The study showed similar effects of particular drugs on the evaluated parameters. After 2-year treatment the EDSS value was 2.6±1.3 points (an increase by 0.3 points). The value of the ARR decreased to 0.55 (a reduction by 32.9%). A significant difference in disease progression was found in MRI scans: at 1 year in 87.0% patients without progression and 42.9% patients in 2 year. The results of this study showed the following: similar effects of particular drugs, treatment with disease modifying drugs has a stabilising effect on disability progression only in some patients, a favourable effect of DMD on slow-down of the disease duration was observed during the second year of treatment and the relapses are the most important clinical indicator of disease unresponsiveness.

Stwardnienie rozsiane (łac. sclerosis multiplex, SM) to przewlekła choroba ośrodkowego układu nerwowego, stanowi też główną przyczyną niepełnosprawności (nieurazowej) w populacji młodych dorosłych. Lekami, które zgodnie z wynikami badań klinicznych mają wpływ na przebieg choroby, są: interferony beta (IFN-β-1a i IFN-β-1b) oraz octan glatirameru (GA). Celem pracy była analiza przebiegu choroby oraz zmian w obrazie rezonansu magnetycznego (RM) mózgu i rdzenia szyjnego u chorych z postacią rzutowo-remisyjną stwardnienia rozsianego (RRSM) u chorych w przebiegu 2-letniej terapii lekami immunomodulującymi (DMD): IFN-β-1b (250 μg), IFN-β-1a (44 μg), IFN-β-1a (30 μg) oraz GA (20 mg). Badanie trwało 24 miesiące. Materiał kliniczny stanowiło 118 chorych z RRSM. Grupa chorych, u których włączono leczenie, to: 20 osób leczonych IFN-β-1a (30 μg), 40 – IFN-β-1b (250 μg), 33 – IFN-β-1a (44 μg) i 25 – GA (20 mg). W badanej grupie przeważały kobiety – 66,1%. Średni wiek chorych wynosił 29,0±8,6 (18-50) roku; wartość EDSS w chwili rozpoczęcia leczenia – 2,3±0,9 pkt; roczny wskaźnik rzutów (ARR) – 0,82. W badaniu stwierdzono podobny wpływ poszczególnych leków na oceniane parametry. Po dwóch latach leczenia wartość EDSS wyniosła 2,6±1,3 pkt (wzrost o 0,3 pkt). Zaobserwowano zmniejszenie rocznego wskaźnika rzutów (ARR) do 0,55 (redukcja o 32,9%). Stwierdzono wyraźną różnicę progresji choroby w ocenie RM – po pierwszym roku progresję stwierdzono u 87,0% chorych, po drugim roku leczenia – u 42,9%. Wyniki przeprowadzonych badań wskazują, że badane leki działają podobnie na postęp choroby, leczenie DMD wpływa stabilizująco na narastanie niesprawności tylko u części chorych, korzystny wpływ leczenia immunomodulującego obserwowano szczególnie w drugim roku leczenia, a obecność nowych rzutów choroby w trakcie kuracji jest najważniejszym klinicznym wykładnikiem braku odpowiedzi na leczenie.
