摘要
Background: Results for the e4/e2 alleles of the ApoE gene as markers of susceptibility, clinical and radiological progression, and cognitive deterioration in patients with multiple sclerosis (MS) are contradictory. Aim: The usefulness of these markers in predicting the response to interferon-beta-1b (IFN beta-1b) was evaluated. Material and Methods: 95 patients with relapsing-remitting MS treated with IFN beta-1b (mean follow-up 7.44 years) were studied. We correlated the e4 and e2 alleles with the time to the first relapse or to a 1-point worsening on the Expanded Disability Status Scale, time to moderate disability, progression index, and treatment discontinuation due to inefficacy. Results: We found no association between the e4 allele and any of the variables. The e2 allele was associated with increased time to moderate disability. Conclusion: The e4 allele of ApoE has no prognostic value for the response to IFN beta-1b. The e2 allele delayed the progression of disability in our MS patient cohort. Copyright (C) 2011 S.
