ABSTRACT
BACKGROUND: Alemtuzumab, is a compound approved for highly active MS, and, in Europe, employed after the use of other disease-modifying treatments (DMTs) with an escalation approach or used as a first therapeutic option. The occurrence of secondary autoimmune adverse events and or infections can differ depending on the employed approach. OBJECTIVE: To evaluate the efficacy and safety of alemtuzumab in real-world MS population that encompassed patients previously treated with other DMTs. METHODS: 35 patients, treated with alemtuzumab in a single MS Center, were followed for at least 36 months. The study investigated the prevalence of patients reaching the phase of the non-active disease (NEDA-3). All the adverse events were also reported, and correlations assessed. RESULTS: At the 36-month follow-up, 66,7% of patients achieved the NEDA-3 status, 90,5% of the patients were relapse-free, 85,7% showed no signs of disability progression, nor signs of MRI activity. Adverse events were observed in 45,7% of the patients and ranked as severe in 23% of them. Cases of autoimmune hemolytic anemia (AIHA), pancytopenia, viral hepatitis E, and noninfectious meningo-encephalomyelitis were found and reported. For these complications, the post hoc analysis showed possible interactive factors and causality related to previous DMT treatments. CONCLUSIONS: In a real-world MS population like the one investigated in our study, alemtuzumab was found to be an effective treatment when employed as an escalation or rescue therapy. The compound exhibits a variable safety profile and frequent adverse events that are likely depending on previous treatments and their impact on the immune system.

Nail loss might represent a new, reversible, adverse event associated with teriflunomide treatment. It shares close analogies with hair loss and thinning, known adverse events of teriflunomide. MS specialists should be aware of this possibility and evaluate treatment discontinuation.

We evaluated efficacy of natalizumab in relapsing-remitting multiple sclerosis patients in a clinical practice setting. We report data on the first consecutive 343 patients receiving natalizumab in 12 multiple sclerosis (MS) Italian centers enrolled between April 2007 and November 2010. The main efficacy endpoints were the proportion of patients free from relapses, disease progression, combined clinical activity, defined as presence of relapse or disease progression, from MRI activity, and from any disease activity defined as the absence of any single or combined activity. At the end of follow-up, the cumulative proportion of patients free from relapses was 68%; the proportion of patients free from Expanded Disability Status Scale (EDSS) progression was 93%; the proportion of patients free from combined clinical activity was 65%; the proportion of patients free from MRI activity was 77%; and the proportion of patients free from any disease activity was 53%. Natalizumab was effective in reducing clinical and neuroradiological disease activity. Its effectiveness in clinical practice is higher than that reported in pivotal trials and was maintained over time.
