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.
Insights
One year of interferon beta-1a (IFNbeta-1a) treatment did not alter quality of life in relapsing-remitting multiple sclerosis (RRMS) patients. Mild side effects were reported but did not impact quality of life.
Area of Science:
- Neurology
- Immunology
- Pharmacology
Background:
- Relapsing-remitting multiple sclerosis (RRMS) is a chronic autoimmune disease.
- Interferon beta-1a (IFNbeta-1a) is a common treatment for RRMS.
- Understanding the long-term impact of IFNbeta-1a on patient well-being is crucial.
Purpose of the Study:
- To evaluate the 12-month effect of interferon beta-1a (IFNbeta-1a) on quality of life (QOL) in RRMS patients.
- To assess changes in disability, independence, cognition, mood, and fatigue.
- To analyze the frequency and severity of IFNbeta-1a side effects and their correlation with QOL.
Main Methods:
- A 12-month follow-up study involving 27 RRMS patients treated with IFNbeta-1a (Avonex).
- Assessment of QOL, disability, independence, cognition, depression, anxiety, and fatigue at baseline, 6, and 12 months.
- Weekly self-reported questionnaires on side effect frequency and severity post-injection.
Main Results:
- Patient quality of life (QOL) showed no significant change over the 12-month follow-up period.
- The percentage of patients reporting side effects remained constant, but the mean number of side effects increased significantly from month 6 to 12.
- Mild side effects did not diminish over time, did not lead to treatment discontinuation, and did not correlate with QOL.
- Disability progression was found to correlate with patient QOL.
Conclusions:
- One-year treatment with interferon beta-1a (IFNbeta-1a) did not significantly alter patient quality of life in RRMS.
- While side effects were persistent and increased over time, they were mild and did not negatively impact QOL or lead to treatment cessation.
- Disability progression is a key factor influencing QOL in RRMS patients undergoing IFNbeta-1a therapy.
