Can Glatiramer Acetate Prevent Cognitive Impairment by Modulating Oxidative Stress in Patients with Multiple Sclerosis?

Multiple sclerosis (MS) is an autoimmune disease characterized by demyelination and neuroinflammation, often accompanied by cognitive impairment. This study aims (1) to investigate the potential of glatiramer acetate (GA) as a therapy for preventing cognitive decline in patients with MS (pwMS) by modulating oxidative stress (OS) and (2) to seek out the differences in cognition between pwMS in a cohort exhibiting good clinical evolution and control subjects (CS). An exploratory, prospective, multicentre, cross-sectional case-control study was conducted, involving three groups at a 1:1:1 ratio-41 GA-treated pwMS, 42 untreated pwMS, and 42 CS.

Reliability, validity and distribution of the Spanish female sexual function index in women with relapsing multiple sclerosis.

Background: The Female Sexual Function Index (FSFI) is a widely recognized tool for assessing sexual dysfunction (SD). However, its validation for Spanish women suffering from multiple sclerosis (MS) has not yet been conducted.

Aim: The study aimed to examine the psychometric properties of the 19-item Spanish version of the FSFI (svFSFI) in women with relapsing MS.

Seroprevalence of SARS-CoV-2 in Patients with Multiple Sclerosis under Disease-Modifying Therapies: A Multi-Centre Study.

Background: The EMCOVID project conducted a multi-centre cohort study to investigate the impact of COVID-19 on patients with Multiple Sclerosis (pwMS) receiving disease-modifying therapies (DMTs). The study aimed to evaluate the seroprevalence and persistence of SARS-CoV-2 antibodies in MS patients enrolled in the EMCOVID database. The DMTs were used to manage MS by reducing relapses, lesion accumulation, and disability progression.

Prophylactic treatment can modify vascular risk biomarkers in high-frequency episodic and chronic migraine patients: a pilot study.

To evaluate whether preventive treatment can modify endothelial and oxidative biomarkers of vascular disease risk in patients with high-frequency episodic and chronic migraine. In this observational, prospective pilot study, 88 prophylactic treatment-naïve patients with episodic and chronic migraine and 56 healthy sex/age matched controls underwent ultrasonography exams and blood tests at baseline, and again in the migraine patients after 3 months' treatment with metoprolol or topiramate. Biomarkers for endothelial function and oxidative stress were analyzed.

Antibodies against the flotillin-1/2 complex in patients with multiple sclerosis.

Multiple sclerosis is a tissue-specific autoimmune disease of the central nervous system in which the antigen(s) remains elusive. Antibodies targeting the flotillin-1/2 complex have been described in 1-2% of the patients in a recent study. Other candidate antigens as anoctamin-2 or neurofascin-155 have been previously described in multiple sclerosis patients, although their clinical relevance remains uncertain.

Effects of Vortioxetine on Cognition and Fatigue in Patients with Multiple Sclerosis and Depression: A Case Series Study.

Introduction: Vortioxetine is a multimodal antidepressant drug that has been reported to have a positive impact on cognition, social function, and fatigue. Nevertheless, it has not been widely studied. Our objective was to explore the effects of vortioxetine on these and other parameters in patients with multiple sclerosis (MS) and depression.

A prospective study of cellular immune response to booster COVID-19 vaccination in multiple sclerosis patients treated with a broad spectrum of disease-modifying therapies.

Background: Most people with Multiple Sclerosis (pwMS) are subjected to immunomodulatory disease-modifying treatments (DMTs). As a result, immune responses to COVID-19 vaccinations could be compromised. There are few data on cellular immune responses to the use of COVID-19 vaccine boosters in pwMS under a broad spectrum of DMTs.

Preventive treatment can reverse cognitive impairment in chronic migraine.

Objective: To study the impact of chronic migraine (CM) on the cognition and quality of life (QoL) of patients in the interictal period, and to analyse the degree of reversibility of any observed alterations following the use of preventive treatment.

Background: CM is a highly disabling disease, and migraineurs often have associated comorbidities, such as subjective memory problems, that are involved in the development of cognitive impairment. Our hypotheses are that patients suffering from chronic migraine experience objective cognitive alterations that are not only due to the pain that they suffer or their current emotional state.

The efficacy of combining topiramate and 4-aminopyridine to reduce relapses and interictal progression in two cases of episodic ataxia type 2.

Background: Episodic ataxia type 2 is an autosomal dominant channelopathy, caused by genetic variants in the voltage-dependent calcium channel a-1 subunit (CACNA1A), which is characterized by intermittent episodes of vertigo and ataxia. A slow progression of cerebellar signs is commonly observed in the course of the disease. Treatment with the carbonic anhydrase inhibitor acetazolamide is recommended.

Seroprevalence of SARS-CoV-2 in a Cohort of Patients with Multiple Sclerosis under Disease-Modifying Therapies.

Background: Disease-modifying therapies (DMTs) used to treat multiple sclerosis (MS) alter the immune system and therefore increase the risk of infection. There is growing concern about the impact of COVID-19 on patients with MS (pwMS), especially those treated with DMTs. Methods: This is a single-center prospective observational study based on data from the Esclerosis Múltiple y COVID-19 (EMCOVID-19) study.

Impairment of Mitochondrial Redox Status in Peripheral Lymphocytes of Multiple Sclerosis Patients.

Literature suggests that oxidative stress (OS) may be involved in the pathogenesis of multiple sclerosis (MS), in which the immune system is known to play a key role. However, to date, the OS in peripheral lymphocytes and its contribution to the disease remain unknown. The aim of the present study was to explore the influence of OS in peripheral lymphocytes of MS patients.

A study to evaluate the effect of ultrasound treatment on nodules in multiple sclerosis patients.

Unlabelled: Purpose/aim: Ultrasound has demonstrated anti-inflammatory and pain-relief benefits in several conditions such as cellulite or trauma events. We assessed the efficacy of ultrasound therapy on nodules associated with first-line treatments in multiple sclerosis patients.

Materials And Methods: Twenty-two multiple sclerosis patients were enrolled during 2013 and randomized to two groups: in the control group patients were treated only with a conventional gel prescribed for cellulite and nodules, while in the experimental group the gel was combined with ultrasound therapy.

Levels of membrane fluidity in the spinal cord and the brain in an animal model of amyotrophic lateral sclerosis.

A mutant form of the copper/zinc superoxide dismutase (SOD1) protein is found in some patients with amyotrophic lateral sclerosis (ALS). Alteration of the activity of this antioxidant enzyme leads to an oxidative stress imbalance, which damages the structure of lipids and proteins in the CNS. Using fluorescence spectroscopy, we monitored membrane fluidity in the spinal cord and the brain in a widely used animal model of ALS, the SOD(G93A) mouse, which develops symptoms similar to ALS with an accelerated course.

Monitoring systemic oxidative stress in an animal model of amyotrophic lateral sclerosis.

A mutant form of the ubiquitous copper/zinc superoxide dismutase (SOD1) protein has been found in some patients with amyotrophic lateral sclerosis (ALS). We monitored oxidative stress in an animal model of ALS, the SOD(G93A) mouse, which develops a disease similar to ALS with an accelerated course. The aim of this work was to show that ALS damages several organs and tissues, from an oxidative stress point of view.
