Mortality in multiple sclerosis: a review.
2008
This work was undertaken to evaluate studies on mortality caused by multiple sclerosis (MS), to evaluate if useful inferences can be drawn from survival studies that can be applied to clinical practice. A literature search was carried out to find epidemiological studies on MS prognosis, survival, mortality and causes of death relevant to our aim. The World Health Organization (WHO) reports on worldwide cause-specific mortality were also considered. Studies were evaluated according to the duration of the follow-up study, the year of publication and the methodology used. We evaluated MS survival from a methodological point of view and considered if time trends could be drawn from study result…
Molecular hydrogen (H 2 ) as a potential treatment for acute and chronic fatigue
2020
Many diseases as well as acute conditions can lead to fatigue, which can be either temporary or chronic in nature. Acute fatigue develops frequently after physical exercise or after alcohol hangover, whereas microbial infections such as influenza or COVID-19 and chronic diseases like Parkinson's disease or multiple sclerosis are often associated with chronic fatigue. Oxidative stress and a resulting disturbance of mitochondrial function are likely to be common denominators for many forms of fatigue, and antioxidant treatments have been shown to be effective in alleviating the symptoms of fatigue. In this study, we review the role of reactive oxygen and nitrogen species in fatigue and the an…
The role of paraoxonase 1 (PON1) as an oxidation marker, in muscle improvement after increased beta-hydroxybutyrate (BHB) in blood, in patients with …
2020
Various studies have concluded that in multiple sclerosis (MS) metabolic changes related to energy alterations are generated at the mitochondrial level. These changes produce loss of muscle mass and lead to high levels of oxidative stress related to low levels of the enzyme Paraoxonase 1 (PON1). The ketone bodies, mainly beta-hydroxybutyrate (BHB), restore this energetic alteration by improving muscular activity. This pilot study was conducted over 4 months with 51 patients diagnosed with MS, randomly divided into: an intervention group that received an isocaloric diet of a Mediterranean origin supplemented with 60 ml of coconut oil; and a control group that received the same base diet but …
An overview of randomized controlled trials on endovascular treatment for chronic cerebrospinal venous insufficiency in multiple sclerosis patients
2021
About ten years ago it was hoped that venous angioplasty for abnormal veins, primarily the internal jugular veins, will be a much awaited treatment for multiple sclerosis. Yet, a majority of randomized clinical trials on endovascular treatment for chronic cerebrospinal venous insufficiency did not reveal clinical efficacy of these procedures in multiple sclerosis patients. Still, a detailed analysis of these trials suggests that they were poorly designed, underpowered and endovascular techniques used were often far from being optimal. Nonetheless, even considering weak points of these trials, it can be concluded that venous angioplasty should not be used as a routine treatment modality in m…
Three different approaches to cognitive fatigue in patients with a mild form of multiple sclerosis : objective cognitive, subjective cognitive and ne…
2017
Tämän tutkimuksen tarkoitus oli arvioida kognitiivista uupumusta lievää multippeli skleroosin (MS) muotoa sairastavilla potilailla kolmea eri lähestymistapaa käyttäen: objektiivista kognitiivista, subjektiivista kognitiivista ja neurofysiologista. Objektiivista kognitiivista uupumusta arvioitiin tarkkaavuuden ylläpitoa, reaktionopeutta ja työmuistia mittaavilla tehtävillä. Subjektiivista kognitiivista uupumusta sekä elämänlaatua arvioitiin itsearvioilla. Neurofysiologiset mittaukset käsittivät aivojen sähköiin herätevasteisiin perustuvia observaatioita. Mittareina olivat kontingentti negatiivinen variaatio (CNV) ja P3. Tutkimukseen osallistui 20 MS-tautia sairastavaa ja 20 verrallistettua t…
Cognitive Impairment in Multiple Sclerosis Is Reflected by Increased Susceptibility to the Sound-Induced Flash Illusion
2019
Objective: To determine whether the performance of multiple sclerosis (MS) patients in the sound-induced flash illusion (SiFi), a multisensory perceptual illusion, would reflect their cognitive impairment.Methods: We performed the SiFi task as well as an extensive neuropsychological testing in 95 subjects [39 patients with relapse-remitting MS (RRMS), 16 subjects with progressive multiple sclerosis (PMS) and 40 healthy control subjects (HC)].Results: MS patients reported more frequently the multisensory SiFi than HC. In contrast, there were no group differences in the control conditions. Essentially, patients with progressive type of MS continued to perceive the illusion at stimulus onset a…
The diagnosis of multiple sclerosis: pinpointing the concept of "no better explanation"

Predictors for Therapy Response to Intrathecal Corticosteroid Therapy in Multiple Sclerosis
2019
\(\bf Objective:\) The autoimmune disease Multiple Sclerosis (MS) represents a heterogeneous disease pattern with an individual course that may lead to permanent disability. In addition to immuno-modulating therapies patients benefit from symptomatic approaches like intrathecal corticosteroid therapy (ICT), which is frequently applied in a growing number of centers in Germany. ICT reduces spasticity, which elongates patient's walking distance and speed, thus improves quality of life. \(\bf Methods:\) In our study we set out to investigate cerebrospinal fluid (CSF) parameters and clinical predictors for response to ICT. Therefore, we analyzed 811 CSF samples collected from 354 patients over …
Chronic cerebrospinal venous insufficiency: state of the art and research challenges
2012
This review discusses a potential vascular basis for multiple sclerosis (MS). The idea that MS could be related to vascular disease is not new, with the first reports describing connections between veins and MS plaques dating from the 19th century. The venous abnormalities found in MS patients, the socalled chronic cerebrospinal venous insufficiency, are currently interpreted as congenital venous malformations. Catheter venography is regarded as the gold standard to assess these lesions, while other tests, such as Doppler sonography and magnetic resonance venography, are much less accurate. Importantly, a relationship between venous pathologies and MS has not yet been proven, especially reg…
SAT0390 Microrna Expression Profile in Fibromyalgia Patients: A Pilot Matched Case Control Study
2013
Background Fibromyalgia (FM) is a clinical syndrome characterized by musculoskeletal pain and tenderness. Diagnosis is mainly based on exclusion of other resembling diseases since validated biological tests are still lacking. Identification of disease-related markers will enable clinicians to effectively diagnose FM, follow the progress of the disease, monitor the effects of therapeutic approaches and probably develop preventive programs. MicroRNAs (miRNAs) are pieces of 18-25 nucleotides capable of regulating gene expression. Changes in their expression levels have been linked to environmental responses as well as to pathological processes. Their recent association to some other chronic di…
