Interferon ß-1b-neutralizing antibodies 5 years after clinically isolated syndromeHartung, Hans-Peter ...Objective: To determine the frequency and consequences of neutralizing antibodies (NAbs) in patients with a first event suggestive of multiple sclerosis (MS) treated with interferon beta-1b ... (IFNbeta-1b). Methods: In the Betaseron/Betaferon in Newly Emerging MS For Initial Treatment (BENEFIT) study, patients were randomly assigned to 250 mug IFNbeta-1b (Betaferon) or placebo subcutaneously every other day for 2 years or until diagnosis of clinically definite MS (CDMS). Patients were then offered open-label IFNbeta-1b for up to 5 years. NAb status was assessed every 6 months by the myxovirus protein A induction assay. A titer >20 NU/mL was considered NAb-positive, with low (>/=20-100 NU/mL), medium (>/=100-400 NU/mL), and high (>/=400 NU/mL) titer categories. Here we examine early-treated patients, who received IFNbeta-1b for up to 5 years. Results: NAbs were measured in 277 of 292 early-treated patients and detected at least once in 88 (31.8%) patients,with 53 (60.2%) reverting to NAb negativity by year 5. Time to CDMS,time to confirmed disability progression, and annualized relapse rate didnot differ between NAb-positive and NAb-negative patients or between periods of NAb positivity vs NAb negativity within patients. Increases in newly active lesion number and T2 lesion volume and conversion to McDonald MS were associated with NAb positivity and were more pronounced with higher titers. Conclusions: Although NAb positivity was associated with increased brain MRI activity, no discernible effects on clinical outcomes were found. This finding may reflect the greater power of MRI compared with clinical outcomes to detect the treatment effects of IFNbeta-1b and may also result from temporal changes in NAb titers and biology.Vir: Neurology. - ISSN 0028-3878 (Vol. 77, issue 9, 2011, str. 835-843)Vrsta gradiva - članek, sestavni delLeto - 2011Jezik - angleškiCOBISS.SI-ID - 29404889
