A snapshot on patient-reported outcome measures of people with multiple sclerosis on first-line therapies in a real world setting.

BACKGROUND: Patient-reported outcomes (PROs) may help patients and clinicians in selecting disease-modifying therapies (DMTs) for multiple sclerosis (MS). OBJECTIVE: To evaluate PRO differences among first-line DMTs for relapsing-remitting (RR) people with MS (pwMS). METHODS: Multicenter study. RR pwMS on first-line DMTs completed Fatigue Severity Scale (FSS), PROs Indices for MS (PRIMUS), 36-item Short-Form Health Survey (SF-36), treatment satisfaction questionnaire for medication (TSQM), Beck Depression Inventory-II (BDI-II), and Symbol Digit Modalities Test (SDMT). Differences among PROs across DMTs were tested by ANOVA. Multivariable linear regressions were used to investigate associations between PROs and the treatment group. RESULTS: Two-hundred eighty pwMS were enrolled: 56% were on interferons (INF), 22% on dimethylfumarate (DMF), 13% on glatiramer acetate, and 9% on teriflunomide (Teri). Compared with INF, pwMS on Teri were the oldest, with higher disability, worst depression at BDI, worst cognitive performances at SDMT (p = 0.001), fatigue at FSS (p = 0.001), and activity limitation and quality of life respectively at PRIMUS (p = 0.005) and SF-36 Mental Composite Score (p < 0.001); pwMS on DMF reported highest side effects and, together with pwMS on Teri, better treatment satisfaction at TSQM. CONCLUSIONS: Compared with INF-treated patients, pwMS on DMF and Teri reported the best treatment satisfaction, although DMF-treated pwMS reported higher side effects and those on Teri the worst QoL and fatigue; however, the older age, higher disability and depression, and worse cognitive performance of pwMS on Teri suggest to be careful in evaluating these results.

Retinal vascular density in multiple sclerosis: a 1-year follow-up.

BACKGROUND AND PURPOSE: Vascular pathology is increasingly acknowledged as a risk factor for multiple sclerosis (MS). Vascular density (VD) is reduced in the eyes of patients with MS on optical coherence tomography (OCT) angiography. We performed a 1-year prospective study to estimate VD variations over time and possible clinical correlates. METHODS: A total of 50 patients with MS underwent spectral domain-OCT and OCT angiography at baseline and after 1-year follow-up. Mixed-effect linear regression models were used to assess variations of each OCT measure and its relation to treatment and clinical outcomes. RESULTS: We observed an increase in parafovea VD (coefficient, 1.147; 95% confidence interval, 0.081-2.214; P = 0.035). Reduction in parafovea VD was associated with increase in Expanded Disability Status Scale score (coefficient, -0.969; 95% confidence interval, -1.732/-0.207; P = 0.013). CONCLUSIONS: Retinal VD can improve over time in MS, particularly in patients experiencing disease stability. Longer follow-up, inclusion of early MS cases and combination with conventional markers of MS severity (i.e. brain atrophy) are needed to better define VD as a potential new biomarker.
