Fatigue at enrollment predicts EDSS worsening in the New York State Multiple Sclerosis Consortium.

BACKGROUND: Fatigue is one of the most common and distressing symptoms among persons with multiple sclerosis (pwMS). OBJECTIVE: The aim of this study is to evaluate fatigue as a predictor for disease worsening among pwMS. METHODS: In this retrospective cohort study of New York State MS Consortium (NYSMSC) registry, MS patients reporting moderate-to-severe fatigue at study enrollment (n = 2714) were frequency matched to less-fatigued subjects (n = 2714) on age, baseline Kurtzke Expanded Disability Status Scale (EDSS), disease duration, and MS phenotype. Change from baseline patient-reported outcomes (PROs), as measured by LIFEware™, categorized participants into two groups: those with stable/improved outcomes and those who worsened. In a subgroup of patients with longitudinal data (n = 1951), sustained EDSS worsening was analyzed using Cox proportional hazards modeling to explore the effect of fatigue. RESULTS: The median survival time from study enrollment to sustained EDSS worsening was 8.7 years (CI: 7.2-10.1). Participants who reported fatigue at baseline were more likely to experience sustained EDSS worsening during follow-up (HR: 1.4, 95% CI: 1.2-1.7). Patients who were fatigued at baseline were also more likely to report worsening psychosocial limitations (all ps ⩽ 0.01). CONCLUSION: In addition to being a common symptom of MS, severe fatigue was a significant predictor for EDSS worsening in the NYSMSC.

An Update on the Use of Disease-Modifying Therapy in Pregnant Patients with Multiple Sclerosis.

The active management of multiple sclerosis (MS) has been made possible during the last two decades with the advent of disease-modifying therapies (DMTs), leading to improved clinical outcomes for many patients. Furthermore, with the realization that MS does not adversely affect pregnancy outcome and that pregnancy does not have an overall negative impact on the long-term disease course of MS, the importance of appropriate counseling and discussion of future pregnancy plans with women of childbearing age is greater than ever. Although several DMTs are licensed for the treatment of MS, none are specifically approved for use during pregnancy or breastfeeding and the use of DMTs during these periods frequently gives rise to concerns regarding potential risks to the fetus. The outcomes of studies in patients with MS treated with DMTs during pregnancy and immediately postpartum have been the focus of several recently published papers. Given the high level of interest surrounding the prescribing of DMTs for MS patients of childbearing age, and the lack of clear guidance in this respect, the current review presents an up-to-date overview of new data, including observational data on real-world outcomes, that have been published during the last 2 years, and could inform future prescribing decisions.
