title: Interferon beta in multiple sclerosis: relationship between sustained serum IgG levels and clinical outcome.
abstract: We investigated the effects of interferon beta-1a (IFN beta-1a) on specific response towards two immunodominant MBP peptides and on global production of IgG. We evaluated 54 sera from multiple sclerosis (MS) patients at baseline and 1 year after treatment. We did not observe any modification of immune response to the MBP peptides but we noted a significant decrease in mean IgG concentrations in patients with progression of the disease but not in stable patients. These results suggest that IFN beta1a restores or maintains a beneficial immune response.
