We investigated the effect of the functional insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene on the response to interferon-β (IFN-β) therapy in Croatian and Slovenian patients with multiple sclerosis (MS). A total of 275 IFN-β treated MS patients [162 responders (Rs) and 113 nonresponders (NRs)] were genotyped by PCR. The ACE I/D genotype distribution and allele frequencies did not differ between female Rs and NRs. However, male NRs tended to have a greater prevalence of the DD genotype (P=0...

<i>Chronic cerebrospinal venous insufficiency (CCSVI) is a series of stenotic malformations in the cerebrospinal venous outflow routes, which is postulated to cause multiple sclerosis (MS). The hypotheses assumed that CCSVI leads to iron deposition which triggers inflammation and demyelination in MS. Invasive endovascular treatment of CCSVI was initiated based on the previous theory. The present study was designed to validate this hypothesis using a rat model of CCSVI. Bilateral jugular vein ligation (JVL) was performed on female albino rats (n = 15), and sham-operated rats (n = 15) were used as a control group...

The level of granulocyte-macrophage colony-stimulating factor (GM-CSF) increases in some disorders such as vascular dementia, Alzheimer's disease, and multiple sclerosis. We previously reported that in Alzheimer's disease patients, a high level of GM-CSF in the brain parenchyma downregulated expression of ZO-1, a blood-brain barrier tight junction protein, and facilitated the infiltration of peripheral monocytes across the blood-brain barrier. However, the molecular mechanism underlying regulation of ZO-1 expression by GM-CSF is unclear...

We aimed to investigate functional connectivity and variability across multiple frequency bands in brain networks underlying cognitive deficits in primary-progressive multiple sclerosis (PP-MS) and to explore how they are affected by the presence of cortical lesions (CLs). We analyzed functional connectivity and variability (measured as the standard deviation of BOLD signal amplitude) in resting state networks (RSNs) associated with cognitive deficits in different frequency bands in 25 PP-MS patients (12 M, mean age 50...

It is well recognised that the majority of the impact of multiple sclerosis (MS), both personal and societal, arises in the progressive phase where disability accumulates inexorably. As such, progressive MS (PMS) has been the target of pharmacological therapies for many years. However, there are no current licensed treatments for PMS. This stands in marked contrast to relapsing remitting MS (RRMS) where trials have resulted in numerous licensed therapies. PMS has proven to be a more difficult challenge compared to RRMS and this review focuses on secondary progressive MS (SPMS), where relapses occur before the onset of gradual, irreversible disability, and not primary progressive MS where disability accumulation occurs without prior relapses...

Elimination of B cells producing autoantibodies to neuroantigens is considered as beneficial in the treatment of multiple sclerosis. Myelin oligodendrocyte glycoprotein (MOG) is a significant autoantigen in multiple sclerosis. It was shown that MOG-like peptoid AMogP3 can bind autoantibodies produced by pathological lymphocytes. We propose a structure of an innovative drug for targeted elimination of the pool of autoreactive B cells responsible for multiple sclerosis pathogenesis; this compound is a complex of peptoid AMogP3 with Fc fragment of human immunoglobulin...

PURPOSE: Evidence of whether exposure to extremely low-frequency magnetic fields (ELF-MF) is related to central nervous system diseases is inconsistent. This study updates a previous study of the incidence of such diseases in a large cohort of Danish utility workers by almost doubling the period of follow-up. METHODS: We investigated the risks for dementia, motor neurone disease, Parkinson disease, multiple sclerosis and epilepsy among 32,006 men employed at the 99 utility companies that supplied Denmark with electricity during the period 1900-1993...

BACKGROUND AND PURPOSE: Myelin detection is of great value in monitoring diseases such as multiple sclerosis and dementia. However, most MR imaging methods to measure myelin are challenging for routine clinical use. Recently, a novel method was published, in which the presence of myelin is inferred by using its effect on the intra- and extracellular water relaxation rates and proton density, observable by rapid quantitative MR imaging. The purpose of this work was to validate this method further on the brains of 12 fresh, intact cadavers...

An understanding of the new generation of MS drugs in conjunction with the key role MR imaging plays in the detection of disease progression, opportunistic infections, and drug-related adverse effects is of vital importance to the neuroradiologist. Part 1 of this review outlined the current treatment options available for MS and examined the mechanisms of action of the various medications. It also covered specific complications associated with each form of therapy. Part 2, in turn deals with the subject of pharmacovigilance and the optimal frequency of MRI monitoring for each individual patient, depending on his or her unique risk profile...

BACKGROUND: Immunotherapy initiated early after first presentation of relapsing-remitting multiple sclerosis is associated with improved long-term outcomes. One can therefore speculate that early initiation of highly effective immunotherapies, with an average efficacy that is superior to the typical first-line therapies, could further improve relapse and disability outcomes. However, the most common treatment strategy is to commence first-line therapies, followed by treatment escalation in patients who continue to experience on-treatment disease activity...

BACKGROUND: Pre-natal and early life factors may have a role in multiple sclerosis (MS) pathogenesis in some people. However, the reporting of any influence of maternal and perinatal factors on MS risk has been limited. We aimed to study maternal and perinatal characteristics of babies who went on to develop MS. METHODS: Data were analysed from the historical Oxford Record Linkage Study dataset 1970-1989, which incorporated a specialised maternity dataset with record linkage between mother and baby, covering a population of 850,000...

BACKGROUND: Individuals with multiple sclerosis (MS) frequently suffer from impaired sensory function, reduced strength and tremor in the upper limbs, which may interfere with upper limb function. However, upper limb impairment in MS is under-recognized and understudied. We aimed to evaluate the prevalence of upper limb impairment in a large sample of persons with MS; the association between upper limb function and employment status in MS; and the frequency of use of assistive devices aimed at addressing upper limb impairments...

BACKGROUND: Psoriasis and multiple sclerosis (MS) share some risk factors, and fumarates are effective disease-modifying therapies for both psoriasis and MS, suggesting a common pathogenesis. However, findings regarding the occurrence of psoriasis in the MS population are inconsistent. OBJECTIVES: We aimed to estimate the incidence and prevalence of psoriasis in the MS population versus a matched cohort from the general population. METHODS: We used population-based administrative data from the Canadian province of Manitoba to identify 4911 persons with MS and 23,274 age-, sex- and geographically-matched controls aged 20 years and older...

BACKGROUND: Multiple sclerosis (MS) incidence and prevalence is increasing worldwide, with a disproportionally higher rate in women. Recent studies have questioned the presence of a latitudinal gradient in Europe. Ireland is a high prevalence country for MS with a previously reported North-South gradient making it ideal to further explore this concept. OBJECTIVES: In this study we prospectively determined the incidence rate of newly diagnosed MS in Ireland over a 12-month period and demonstrated the presence of a North-South gradient...

Paroxysmal tonic spasms [PTS] are common in patients with neuromyelitis optica spectrum disorder (NMOSD).1 2 In patients with demyelinating disease, PTS can significantly reduce the quality of life, limit activities of daily living and the rehabilitative process following an acute relapse 3. As in patients with multiple sclerosis (MS), paroxysmal tonic spasms in NMOSD usually respond well to treatment with carbamazepine.2 However, the optimal treatment in patients where carbamazepine is contraindicated or poorly tolerated is unclear...

PURPOSE: The process of demyelination in multiple sclerosis (MS) is reflected in lesions of the central nervous system (CNS), which are found in an abundance of different diseases and are frequently radiographically indistinguishable. Our aim was to determine whether the perivenous distribution of MS lesions identified on susceptibility weighted images (SWI) could be used as a specific radiographic sign for MS, and also to determine whether the visibility of the central vein (CV) is affected by the activity of MS lesions...

BACKGROUND: Multiple sclerosis is a central nervous system demyelinating disease with unknown etiology. However, it is believed to be a multifactorial disease resulting from an interaction of genetic and environmental factors. Immigrant studies have been performed to provide a better view of the pattern of this interaction. We aimed to report the prevalence of MS Afghan immigrants of Isfahan, a population who share the same environment as Isfahan residents but with different genetic backgrounds...

An 80-year-old man developed dysarthria, quadriplegia, sensory disturbance and ataxia in all limbs. Brain and spinal magnetic resonance imaging (MRI) revealed multiple enhanced lesions. Cerebrospinal fluid (CSF) levels of adenosine deaminase (ADA) remarkably elevated. Tuberculosis DNA was not detected, and tuberculosis was not cultured either in the CSF. Brain biopsy revealed the inflammatory demyelinating lesions. With the diagnosis of multiple sclerosis, corticosteroid therapy resulted in rapid improvement of his symptoms and MRI abnormalities...
