Abstract

In a 12-month follow-up study, we evaluated 27 patients (18 F and 9 M) with relapsing-remitting (RR) multiple sclerosis (MS), who had started treatment with interferon beta-1a (IFNbeta-1a) (Avonex), 30 microg i.m. once weekly, 6-18 months (median 10 months) before study entry. Quality of life (QOL), disability, independence, cognitive performances, symptoms of depression and anxiety, and fatigue were assessed at baseline, 6 months and 12 months. The frequency and severity of the side effects of treatment, at hours 0-12, 13-48 and 49-168 after the injection, were self-reported weekly in a structured questionnaire. QOL did not change significantly during the follow-up. The percentage of patients who reported side effects after the injection of IFNbeta-1a remained constant during the 52 weeks. The mean number of side effects increased significantly from the 6th to the 12th month. The general linear model analysis of variance disclosed significant changes over time for almost all side effects, but we did not find any correlation between QOL and number of side effects. In conclusion, 1-year treatment with IFNbeta-1a did not significantly change patient's QOL. Disability progression correlated with patient's QOL. Side effects, which were mild, did not diminish over time, did not induce treatment discontinuation and did not interfere with QOL.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
