Bacterial variation in the oral microbiota in multiple sclerosis patients.

BACKGROUND: Microorganisms in oral cavity are called oral microbiota, while microbiome consists of total genome content of microorganisms in a host. Interaction between host and microorganisms is important in nervous system development and nervous diseases such as Autism, Alzheimer, Parkinson and Multiple Sclerosis (MS). Bacterial infections, as an environmental factor in MS pathogenesis play role in T helper 17(Th17) increase and it enhancing the production of pro-inflammatory cytokines such as Interlukin-21(IL-21), IL-17 and IL -22. Oral microbiota consists diverse populations of cultivable …

Role of Monoclonal Antibody "Alemtuzumab" in the Treatment of Multiple Sclerosis.

This article will review current treatment options for multiple sclerosis (MS) while keeping our primary focus on alemtuzumab, as it is now approved in more than 65 countries. From a pathophysiological point of view, MS is a disabling disease impacting a patient's life both physically and mentally, leading to devastating social and economic impact. This review will elaborate on alemtuzumab's role in treating relapsing-remitting MS (RRMS) by comparing its efficacy, side effects, and monitoring with other disease-modifying therapies (DMTs) available in the market. It is a point of great concern …

Immunomodulatory Potential of Cannabidiol in Multiple Sclerosis: a Systematic Review.

Multiple sclerosis (MS) is the most common chronic autoimmune disease of the central nervous system. Efficacy of treatments for MS is associated with risk of adverse effects, and effective and well-tolerated drugs remain a major unmet need. Cannabis (Cannabis sativa L., fam. Cannabaceae) and cannabinoids are popular among MS patients to treat spasticity and pain. Cannabinoids are endowed with remarkable immunomodulating properties, and in particular the non-psychotropic cannabinoid cannabidiol (CBD) is increasingly recognized as anti-inflammatory and immunosuppressive, nevertheless with excell…

Mechanisms of B lymphocyte involvement in the pathogenesis of multiple sclerosis

Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system involving autoimmune mechanisms. MS has been treated as a disorder mediated mainly by T cells for a long time. However, recent findings demonstrate that B lymphocytes are of crucial pathogenetic significance in MS. In patients with MS, B cells can possess both pro-inflammatory and anti-inflammatory effects. The paper reports the main mechanisms of B lymphocyte involvement in the pathogenesis of MS. Diagnostic value of assessing humoral immune parameters in individuals with demyelinating diseases and modern…

An emerging potential of metabolomics in multiple sclerosis: a comprehensive overview.

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the nervous system that primarily affects young adults. Although the exact etiology of the disease remains obscure, it is clear that alterations in the metabolome contribute to this process. As such, defining a reliable and disease-specific metabolome has tremendous potential as a diagnostic and therapeutic strategy for MS. Here, we provide an overview of studies aimed at identifying the role of metabolomics in MS. These offer new insights into disease pathophysiology and the contributions of metabolic pathways to this process…

Neurofilament light chain as a biomarker for diagnosis of multiple sclerosis.

The treatments for multiple sclerosis (MS) have improved over the past 25 years, but now the main question for physicians is deciding who should receive treatment, for how long, and when to switch to other options. These decisions are typically based on treatment tolerance and a reasonable expectation of long-term efficacy. A significant unmet need is the lack of accurate laboratory measurements for diagnosis, and monitoring of treatment response, including deterioration and disease progression. There are few validated biomarkers for MS, and in practice, physicians employ two biomarkers discov…

Uptake and Attitudes About Immunizations in People With Multiple Sclerosis.

OBJECTIVE: By surveying a multiple sclerosis (MS) population, we tested the hypothesis that influenza vaccine uptake would not meet public health targets and that vaccine misconceptions would contribute to lower than desired uptake. METHODS: In spring 2020, we surveyed participants in the North American Research Committee on Multiple Sclerosis Registry regarding vaccinations. Participants reported whether they had received hepatitis A, hepatitis B, pneumococcal, shingles, varicella, measles/mumps/rubella, tetanus, or influenza vaccines. Participants who had not received influenza vaccine last…

The role of TH17 cells in multiple sclerosis: Therapeutic implications.

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS) where immunopathology is thought to be mediated by myelin-reactive CD4+ T helper (TH) cells. The TH cells most commonly implicated in the pathogenesis of the disease are of TH1 and TH17 lineage, which are defined by the production of interferon-γ and interleukin-17, respectively. Moreover, there is emerging evidence for the involvement of TH17.1 cells, which share the hallmarks of TH1 and TH17 subsets. In this review, we summarise current knowledge about the potential role of TH17 subsets in th…

Impaired consolidation of visuomotor adaptation in patients with multiple sclerosis.

BACKGROUND: Apart from inflammation and neurodegeneration, the individual clinical course of multiple sclerosis (MS) might be determined by differential adaptive capacities of the central nervous system. It has been postulated that the retention of adaptive training effects may be impaired in persons with MS (PwMS). OBJECTIVE: To investigate motor adaptation and consolidation capacities of people with MS in a visual motor adaptation task (VAT). METHODS: A total of 23 PwMS (Expanded Disability Status Scale (EDSS) score < 6) and 20 matched healthy controls were recruited. All participants comp…

Fingolimod as a Treatment in Neurologic Disorders Beyond Multiple Sclerosis.

Fingolimod is an approved treatment for relapsing-remitting multiple sclerosis (MS), and its properties in different pathways have raised interest in therapy research for other neurodegenerative diseases. Fingolimod is an agonist of sphingosine-1-phosphate (S1P) receptors. Its main pharmacologic effect is immunomodulation by lymphocyte homing, thereby reducing the numbers of T and B cells in circulation. Because of the ubiquitous expression of S1P receptors, other effects have also been described. Here, we review preclinical experiments evaluating the effects of treatment with fingolimod in ne…

Large primary vaginal stone in a woman with multiple sclerosis.

Vaginal stones are rare and therefore a delay in accurate diagnosis often occurs. We present a 54-year old woman with multiple sclerosis who was diagnosed with a primary vaginal stone. Initially, she presented with recurring urinary tract infections (UTI) and macroscopic haematuria to the urologist. A cystoscopy showed no abnormalities. Because of persistent bleeding, she was referred to the gynaecologist, and on gynaecological examination, a vaginal stone was revealed. Stone formation was likely to be the result of urinary pooling due to incontinence, which was caused by a neurogenic bladder.…

[Progress of ocular motor and structures in multiple sclerosis patients].

Therefore, there have been plenty of researches on the alteration of motor and structures of eyes by MS. This paper reviews and summarizes the progress of MS-related changes of ocular motor, cornea, structure and blood flow of retina, and optic nerve, and may provide a new insight for related clinical researches. (Chin J Ophthalmol, 2020, 56: 711-715).

Nimodipine Reduces Dysfunction and Demyelination in Models of Multiple Sclerosis.

OBJECTIVE: Treatment of relapses in multiple sclerosis (MS) has not advanced beyond steroid use, which reduces acute loss of function, but has little effect on residual disability. Acute loss of function in an MS model (experimental autoimmune encephalomyelitis [EAE]) is partly due to central nervous system (CNS) hypoxia, and function can promptly improve upon breathing oxygen. Here, we investigate the cause of the hypoxia and whether it is due to a deficit in oxygen supply arising from impaired vascular perfusion. We also explore whether the CNS-selective vasodilating agent, nimodipine, may p…

Aminopiridines in the treatment of multiple sclerosis and other neurological disorders.

Symptomatic treatment has a great relevance for the management of patients with neurologic diseases, since it reduces disease burden and improves quality of life. Aminopyridines (APs) are a group of potassium (K+) channel blocking agents that exert their activity both at central nervous system level and on neuromuscular junction. This review describes the use of APs for the symptomatic treatment of neurological conditions. We will describe trials leading to the approval of the extended-release 4-aminopyridine for MS and evidence in support of the use in other neurological diseases.
