Navigating the discontinuation of multiple sclerosis first line treatments : A paradigm shift in patient care
Copyright © 2024. Published by Elsevier B.V..
BACKGROUND: This retrospective study, conducted between 2005 and 2016, investigated the outcomes of patients with multiple sclerosis (MS) who discontinued injectable first-line disease-modifying therapies (DMTs). The study aimed to identify factors influencing treatment discontinuation and assess the impact of discontinuation on disease progression.
METHODS: Data was collected from 2,270 patients who received injectable DMTs for at least two years and subsequently discontinued treatment due to clinical and MRI remission, side effects, or noncompliance. Patients were categorized into two groups: those stable after discontinuation (SAD) and those with relapse after discontinuation (RAD). Survival analysis and logistic regression were employed to assess factors influencing treatment discontinuation.
RESULTS: Of the 60 patients who discontinued DMTs, one-third (n = 20) remained stable, while 40 patients experienced clinical and/or MRI activity during follow-up. The SAD group had a significantly later age at treatment discontinuation compared to RAD patients (35.9 ± 11.1 vs. 30.7 ± 6.1, p = 0.025). Patients below 40 years old had a higher likelihood of experiencing worsening (75 %), while those over 50 years old demonstrated an 80 % stability rate. SAD patients used DMTs for a more extended period than RAD patients (69.1 ± 47.3 vs. 46.6 ± 20.3 months, p = 0.012). A notable proportion (42.9 %) of worsened patients discontinued DMTs without consulting a physician, emphasizing potential challenges in treatment adherence. After treatment discontinuation, RAD patients experienced relapses after a median of 21.0 months. Survival analysis suggested a more favorable disease course for patients who discontinued treatment after achieving a stable period (p = 0.237), with evidence of differentiation between groups after four years. Regression analysis indicated that older age at discontinuation had a favorable impact on relapse probability (HR: 0.904; p = 0.031; 95 % CI: 0.825, 0.991). Reasons for discontinuation unrelated to disease stability showed a positive but imprecise effect on relapse probability.
CONCLUSION: This study provides insights into the outcomes of MS patients discontinuing injectable DMTs, emphasizing the importance of age at discontinuation and reasons for treatment cessation in predicting disease progression. The findings suggest that discontinuation after achieving stability may lead to more favorable outcomes, highlighting the need for personalized treatment decisions in MS management. Further research is warranted to validate these findings and inform clinical practices.
