520 | a Interferon-β-1b (IFN-β-1b) is an immunomodulatory therapy of multiple sclerosis (MS), reducing the numbers and severity of exacerbations and the total lesion load measured by magnetic resonance imaging of the brain. The benefits of IFN-β-1b could be hampered by the development of neutralising antibodies against the compound. Our results confirmed earlier studies, showing that 42% of MS patients treated with IFN-β-1b for more than 3 months had developed neutralising antibodies. The occurrence of binding anti-IFN-β-1b antibodies, presently not believed to impede the clinical efficacy of IFN-β-1b, were demonstrated by an immunoassay in some patients already after I month of treatment and in 78% after 3 months. The development of binding antibodies seemed to be an early phenomenon, preceding the appearance of neutralising antibodies. Antibodies crossreacting with IFN-β-1a and natural IFN-β were also found in a majority of IFN-β-1b treated patients with high titres of binding antibodies. Employing a solid-phase enzyme-linked immunospot (ELISPOT) assay, 68% of MS patients treated with IFN-β-1b for 1 -23 months had elevated numbers of anti-IFN-β-1b-antibody secreting cells in blood, compared to 18% of untreated MS patients and 20% among patients with other neurological diseases. Thus, our findings confirm that IFN-β-1 b is immunogenic in MS patients. High levels of anti-IFN-β-1b antibody secreting cells were, however, also found in two untreated control patients with inflammatory diseases, suggesting that anti-IFN-β-1b antibodies might also occur spontaneously. | |
