Teriflunomide treatment outcomes in multiple sclerosis: A Portuguese real-life experience.

Teriflunomide is an oral disease-modifying therapy for relapsing-remitting multiple sclerosis patients. A decline in physical and cognitive functions, which negatively impacts their quality of life (QoL), is observed in relapsing-remitting multiple sclerosis patients. The aim of this study was to characterise adult Portuguese relapsing-remitting multiple sclerosis patients treated with teriflunomide in routine clinical practice concerning their quality of life, comorbidities, treatment effectiveness, satisfaction, compliance and safety. TeriLIVE-QoL was a multicentre, non-interventional, prospective cohort study that collected demographic and clinical characteristics, patient-reported outcomes and adverse events from patients treated with teriflunomide of 14 mg over 2 years. Notably, around 18 months of this period occurred during the COVID-19 pandemic. Of the 99 participants, 25% were treatment-naïve. Annualised relapse rate and the score for the Hospital Anxiety and Depression Scale decreased after 1 (p = 0.01) and 2 years of treatment (p < 0.001), respectively. Convenience (p = 0.001), effectiveness (p = 0.002) and global satisfaction scores (p < 0.001) presented high values (up to 95.6) and continued to improve along the study. Treatment persistence was 77%, and compliance reached 82% 2 years after initiation. Three patients experienced serious adverse events. TeriLIVE-QoL provides real-world evidence of clinical effectiveness, high treatment satisfaction, consistent safety and improved psychiatric outcomes, associated with elevated treatment persistence and compliance in patients treated with teriflunomide.iance reached 82% 2 years after initiation. Three patients experienced serious adverse events.

Outcomes on Social and Classic Cognition in adults with Pediatric-onset Multiple Sclerosis.

BACKGROUND: Cognitive impairment affecting classic and social domains has been consistently reported in patients with Multiple Sclerosis (MS). However, little is known about the cognitive outcomes, particularly on social cognition, in adults with pediatric-onset multiple sclerosis (POMS). OBJECTIVES: To compare the performance in classic and social cognitive domains between adults with POMS and adult-onset MS (AOMS). METHODS: A group of 30 patients with POMS (age onset <18 years) was compared with age-matched (AOAMS, n=30) and disease duration-matched (AODMS, n= 30) patients who developed MS after the age of 18 years. Cognitive performance was assessed using the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) and Theory of Mind (ToM) tests. RESULTS: Cognitive impairment was more prevalent in POMS patients (40% vs. 16.7%, p=0.045), independently of age or disease duration, affecting more severely information-processing speed and visual memory domains. No statistically significant differences were found in ToM performance between patients with POMS and AOMS. When analyzing ToM performance according to age of disease onset (≤15 years; 15-20 years; ≥20 years), patients with disease onset ≤15 years old had significantly lower scores on ToM tests when compared to the other groups. CONCLUSION: Patients with POMS were more prone to develop impairment on classic cognitive domains than on ToM ability, when compared with AOMS patients. The interference of POMS with critical neurodevelopmental periods, specific for each cognitive domain, may explain different outcomes at adulthood on social and classic cognition.

JC virus antibodies in Portuguese multiple sclerosis patients: JUSTIFY study results.

OBJECTIVE: To confirm anti-JC virus (JCV) antibody seroprevalence in Portuguese patients with relapsing-remitting multiple sclerosis (RRMS) and to determine their anti-JCV antibody index. METHODS: JUSTIFY was a retrospective, multicentre study that included 655 RRMS patients tested at least once with the anti-JCV antibody assay STRATIFY JCV DxSelect. Demographic data, multiple sclerosis history and results of the anti-JCV antibody test were collected, along with physicians' reasons for requesting the test and the impact of the results. RESULTS: Overall anti-JCV antibody seroprevalence was 60.8% (95% confidence interval, 56.9-64.5). Seroprevalence was associated with higher age (P = .030) and was lower in natalizumab-treated patients (P < .001). The mean anti-JCV antibody index of immunosuppressant-naive patients was 1.5 ±â€¯1.3 (n = 378). The main reasons for performing the test were clinical characterization (35.5%) and medication change (26.2%). In patients who switched treatments (n = 109), fingolimod (47.7%) and natalizumab (26.6%) were the most commonly chosen new treatments. CONCLUSIONS: The study confirmed the high anti-JCV antibody prevalence in Portuguese RRMS patients and its association with age. These data can be used to better understand the benefit-risk profile of natalizumab treatment in Portuguese patients and to support progressive multifocal leukoencephalopathy risk management strategies.

New markers of early cardiovascular risk in multiple sclerosis patients: oxidized-LDL correlates with clinical staging.

OBJECTIVES: This study aimed to characterize a population of multiple sclerosis (MS) patients in terms of traditional and new cardiovascular risk factors and assess their putative correlation with clinical disease activity (evaluated by the Expanded Disability Status Scale [EDSS]). METHODS: Thirty relapsing MS patients and 66 subjects, matched by age and sex, were enrolled in this cross-sectional study. For each subject, anthropometric data were collected and classical biochemical (including lipid profile, glucose and C reactive protein [CRP] levels) and novel markers (paraoxonase 1 [PON1] enzyme activity and contents of high-density lipoprotein [HDL] cholesterol, oxidized low-density lipoprotein [Ox-LDL], tumor necrosis factor [TNF]-alfa, vascular endothelial growth factor [VEGF] and adiponectin) were studied. RESULTS: In patients group, 23 women and 7 men were included, aged 35.00 (28.25-40.25) years and scoring a median of 2.00 (1.50-3.13) in EDSS. Comparing with controls, the most relevant differences encountered were: increased serum triglycerides (P< 0.001), Ox-LDL (P< 0.001) as well as Ox-LDL/LDL ratio and reduced small HDL (P=0.040), accompanied by a trend to increased VEGF concentration. LDL content, especially Ox-LDL, showed positive and significant correlation with EDSS (r=0.458; P=0.011) and VEGF (r=0.453; P=0.014). CONCLUSIONS: MS patients presented a profile of early CV risk, being Ox-LDL contents a putative good marker and having correlation with the clinical activity of the disease.
