Background: Managing medication during pregnancy and lactation in multiple sclerosis (MS) patients needs to balance potential risks to the newborn with the substantial risks of ongoing disease activity. Objective: To evaluate the potential transfer of natalizumab (NAT) into breast milk and into the serum of newborn babies in women who continued NAT treatment during pregnancy and lactation. Methods: Serum samples of 11 mother–infant pairs and mother milk samples of a further 4 women were analyzed for free NAT using a HL60 cell-based fluorescence-activated cell sorting (FACS) assay. Two mother–baby pairs were analyzed for cell-bound NAT, very-late-antigen (VLA)-4 expression, and saturation with NAT on immune cells by FACS analysis. Results: In the majority of the mother–infant serum pairs (6/11) and in all breast milk samples, free NAT was detectable. Cell-bound NAT was measurable in both mother–baby pairs with significant higher levels in babies. VLA-4 expression seems to be higher in newborns. Saturation with NAT was comparable between newborns and mothers. Conclusion: NAT can pass placental barrier before delivery and into breast milk. Measurable NAT on neonatal lymphocytes may have functional impact. Further investigations are needed to clarify safety and risk of NAT exposure during pregnancy and lactation.

<p></p> <p><strong><em>Background </em></strong></p> <p>Oral pharmacotherapy has the potential to offer multiple sclerosis patients improved clinical outcomes compared to traditional therapies.</p> <p><strong><em>Objectives </em></strong></p> <p>This review assesses the effects of oral therapies compared to placebo and interferon beta-1a in adults with relapsing-remitting multiple sclerosis (RRMS).</p> <p><strong><em> </em></strong></p> <p><strong><em>Search methods </em></strong></p> <p>We searched the MEDLINE, EMBASE, Cochrane Library, Web of Science (January 1980 to April 2011) and clinincaltrials.gov (April 2011) databases and reference lists of articles. The FDA website was also searched.</p> <p><strong><em>Selection criteria </em></strong></p> <p>Double-blind, placebo-controlled, randomized trials of RRMS patients who were treated with fingolimod, cladribine, laquinimod or interferon beta-1a.</p> <p><strong><em>Data collection and analysis </em></strong></p> <p>Two reviewers independently assessed articles for inclusion. Data extraction and quality assessment was completed by one reviewer and verified for accuracy. Meta-analysis and indirect treatment comparison methods were used to estimate relative measures of efficacy.</p> <p><strong><em>Results </em></strong></p> <p>Although 11 trials involving 7,127 participants were included in this review, only 2,109 (30%) and 1,738 (24%) participants contributed to the direct and indirect estimates respectively, for the primary outcome, annualized relapse rate. Oral therapy and interferon beta-1a had a significantly different rate of relapse compared to placebo (Mean difference [MD] -0.21, 95% confidence interval [CI] -0.27 to -0.16 , p < 0.00001 and MD -0.33 95% CI -0.65 to -0.01). There was a significant risk reduction of 37% and 19% in the number of patients with at least one relapse for oral therapy and interferon beta-1a compared to placebo respectively. Safety analysis favoured placebo for both sets of trials (p=0.002 and p=0.04). Indirect estimates were not significant for all three outcomes however; comparability between direct evidence was noted.</p> <p><strong><em>Conclusions </em></strong></p> <p>Oral pharmacotherapy and interferon beta-1a are effective compared to placebo in controlling relapse rate in patients with RRMS. The indirect measures of effect provide initial estimates of comparative efficacy and incorporation of future evidence will be necessary.</p> / Master of Science (MSc)

The submitted thesis deals with the theme of a neurodegenerative autoimmune disease, the sclerosis multiplex. Although this serious disease has become an object of intensive research in recent decades and there is an inexhaustible quantity of literature available, we haven't yet fully identified the causes of this disease as well as we haven't found such kind of effective treatment that would lead to the permanent recovery of patients. I focused my interest on two main spheres: first, the description and comparison of practices in terms of pharmacotherapy giving priority to its benefits to patients, second, the view of another important but not always appreciated part of therapy, physiotherapy or rehabilitation; the main point is studying of processes and actions from the pedagogical point of view.
