Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that can result in severe morbidity and mortality. The past 15 years have seen a dramatic improvement in the available treatment options for MS patients. Before the 1990s, steroids administered during acute attacks were the only effective medications for the disease. Since then, seven drugs have been approved by the US Food and Drug Administration for use in MS, and many trials investigating new treatments are in progress. The experimental agents range from vaccines to monoclonal antibodies to drugs with novel mechanisms of action. In addition, the importance of vitamin D and its interaction with the immune system has become increasingly apparent. This selective review of current clinical trials provides a concise summary of promising new MS therapies on the horizon.

The Central Nervous System

Currently, there is still no cure for multiple sclerosis (MS), which is an autoimmune and neurodegenerative disease of the central nervous system. Treatment options predominantly consist of drugs that affect adaptive immunity and lead to a reduction of the inflammatory disease activity. A broad range of possible cell-based therapeutic options are being explored in the treatment of autoimmune diseases, including MS. This review aims to provide an overview of recent and future advances in the development of cell-based treatment options for the induction of tolerance in MS. Here, we will focus on haematopoietic stem cells, mesenchymal stromal cells, regulatory T cells and dendritic cells. We will also focus on less familiar cell types that are used in cell therapy, including B cells, natural killer cells and peripheral blood mononuclear cells. We will address key issues regarding the depicted therapies and highlight the major challenges that lie ahead to successfully reverse autoimmune diseases, such as MS, while minimising the side effects. Although cell-based therapies are well known and used in the treatment of several cancers, cell-based treatment options hold promise for the future treatment of autoimmune diseases in general, and MS in particular.

Disease Modifying

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system whose etiology remains unclear. It has been suggested that MS can be triggered by certain viruses; however, human immunodeficiency virus (HIV) infection is associated with reduced incidence of MS. We present the case of a young patient diagnosed with active relapsing-remitting MS whose clinical course substantially improved following HIV infection and treatment. The patient achieved no evidence of disease activity status without any disease-modifying drugs. Both HIV-induced immunosuppression and antiretroviral therapy may have attenuated the clinical course in this patient.

Lipid Structures

: Mammalian nervous systems depend crucially on myelin sheaths covering the axons. In the central nervous system, myelin sheaths consist of lipid structures which are generated from the membrane of oligodendrocytes (OL). These sheaths allow fast nerve transmission, protect axons and provide them metabolic support. In response to specific traumas or pathologies, these lipid structures can be destabilized and generate demyelinating lesions. Multiple sclerosis (MS) is an example of a demyelinating disease in which the myelin sheaths surrounding the nerve fibers of the brain and spinal cord are damaged. MS is the leading cause of neurological disability in young adults in many countries, and its incidence has been increasing in recent decades. Related to its etiology, it is known that MS is an autoimmune and inflammatory CNS disease. However, there are no effective treatments for this disease and the immunomodulatory therapies that currently exist have proven limited success since they only delay the progress of the disease. Nowadays, one of the main goals in the MS research is to find treatments which allows the recovery of neurological disabilities due to demyelination. To this end, different approaches, such as modulating intracellular signaling or regulating the lipid metabolism of OLs, are being considered. Here, in addition to immunosuppressive or immunomodulatory drugs that reduce the immune response against myelin sheaths, we review a diverse group of drugs that promotes endogenous remyelination in MS patients and whose use may be interesting as potential therapeutic agents in MS disease. To this end, we compile specific treatments against MS that are currently in the market with remyelination strategies which have entered into human clinical trials for future reparative MS therapies. The method used in this study is a systematic literature review on PubMed, Web of Science and Science Direct databases up to May 31, 2020. To narrow down the search results in databases, more specific keywords, such as, “myelin sheath”, “remyelination”, “demyelination”, “oligodendrocyte” and “lipid synthesis” were used to focus the search. We favoured papers published after January, 2015, but did not exclude earlier seminal papers.

An 18-year old female patient presented to our Neurosurgical Out-patients’ Clinic with symptoms atypical for multiple sclerosis, unremarkable neurological deficit, one tumefactive lesion on MRI, followed by relapse and another two lesions within a period of six months. We decided to perform biopsy of the tumefactive lesion with compressive effect. Serological and clinical data were negative for MS, and the patient did not respond well to corticosteroid therapy. Fresh frozen tumor tissue aroused a strong suspicion of gemistocytic astrocytoma, so total resection was done, but the definitive pathohistological examination confirmed tumefactive demyelination.</p><p><strong>Conclusion</strong>. For clinicians, it is important to consider demyelinating disease in the differential diagnosis of a tumorlike lesion of the central nervous system, in order to avoid invasive and potentially harmful diagnostic procedures, especially in younger patients.</p>

: There are few diseases with as many therapeutic advances in recent years as in multiple sclerosis. Nine different drug classes with more than a dozen approved therapies are now available. Similarly, there have been unimaginable advances in understanding neuromyelitis optica (now neuromyelitis optica spectrum disorder [NMOSD]) over the past 15 years. Building on the knowledge gained, the first therapies have been approved in recent years. In this review, we aim to present all therapies approved for the treatment of MS or NMOSD. The different forms of application, different approval criteria and most important side effects will be presented. This work is intended for physicians who are interested in MS and NMOSD therapies and want to get a first overview and does not replace the respective guidelines of the regulatory authorities.

Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system (CNS). The diagnosis is based on evidence of at lease two different lesions in the CNS, at least two different episodes in the disease course, and chronic inflammation of the CNS as determined by analysis of the cerebrospinal fluid. Central neuropathic pain is the most common form of pain in patients with MS, with an estimated prevalence of about 50%. Along with the classical neuropathic pain features, such as spontaneous pain (dysesthesia and burning) and evoked pain (allodynia and hyperalgesia), patients with MS may also suffer from intermittent neuropathic pain, such as trigeminal neuralgia, Lhermitte sign, and glossopharyngeal neuralgia. In addition to disease-modifying therapies of MS, multiple treatments are available to manage neuropathic pain secondary to MS, including medical, interventional, and surgical treatments with varying levels of evidence.

Esophageal cancer (EC) is among the most frequent and deadly cancers around the world. While esophageal adenocarcinoma (EAC) has one of the fastest-growing incidences amongst cancers in the US, it also has one of the lowest survival rates due to the limited effective treatment options. Fortunately, in the past decade, two targeted therapies and an immunotherapy agent have been approved by the FDA for metastatic EAC and esophageal squamous cell carcinoma (ESCC), with several more currently being considered for approval. In terms of immunotherapies, in July 2019, the FDA approved the PD1 inhibitor pembrolizumab for second-line treatment of PDL1-positive, advanced or metastatic ESCC. Two years before, pembrolizumab had been approved for the third-line treatment of PDL1-positive EAC. The PD1 inhibitor nivolumab, which was found in one study to outperform chemotherapy irrespective of PDL1 status, has yet to secure FDA approval. In terms of targeted therapies, although as many as 90% of EC cases show upregulated EGFR, anti-EGFR therapy has not been shown to improve survival. Ramucirumab, an antibody targeting both VEGF and HER2/neu receptors, has been approved for the treatment of refractory EAC, while the anti-HER2 monoclonal antibody (mAb) trastuzumab has been approved as front-line treatment for HER2-positive cases which account for approximately 20% of ECs. Although these targeted therapies and immunotherapies have resulted in significant improvements in survival for specific patient populations that are positive for certain biomarkers, such as PDL1 and HER2/neu, the survival rates remain low for a large proportion of the metastatic EC patient population, necessitating the development of further targeted treatment options.

Reduced Penetrance

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the Central Nervous System (CNS). Currently, it is estimated that 30–40% of the phenotypic variability of MS can be explained by genetic factors. However, low susceptibility variants identified through Genome Wide Association Study (GWAS) were calculated to explain about 50% of the heritability. Whether familial high-risk variants also contribute to heritability is a subject of controversy. In the last few years, several familial variants have been nominated, but none of them have been unequivocally confirmed. One reason for this may be that genetic heterogeneity and reduced penetrance are hindering detection. Sequencing a large number of MS families is needed to answer this question. In this study, we performed whole exome sequencing in four multi-case families, of which at least three affected individuals per family were analyzed. We identified a total of 138 rare variants segregating with disease in each of the families. Although no single variant showed convincing evidence for disease causation, some genes seemed particularly interesting based on their biological function. The main aim of this study was to provide a complete list of all rare segregating variants to provide the possibility for other researchers to cross-check familial candidate genes in an unbiased manner.

Reversible Encephalopathy

Multiple sclerosis (MS) is a prevalent and debilitating neurologic condition characterized by widespread neurodegeneration and the formation of focal demyelinating plaques in the central nervous system. Current therapeutic options are complex and attempt to manage acute relapse, modify disease, and manage symptoms. Such therapies often prove insufficient alone and highlight the need for more targeted MS treatments with reduced systemic side effect profiles. Ozanimod is a novel S1P (sphingosine-1-phosphate) receptor modulator used for the treatment of clinically isolated syndrome, relapsing–remitting, and secondary progressive forms of multiple sclerosis. It selectively modulates S1P1 and S1P5 receptors to prevent autoreactive lymphocytes from entering the CNS where they can promote nerve damage and inflammation. Ozanimod was approved by the US Food and Drug Administration (US FDA) for the management of multiple sclerosis in March 2020 and has been proved to be both effective and well tolerated. Of note, ozanimod is associated with the following complications: increased risk of infections, liver injury, fetal risk, increased blood pressure, respiratory effects, macular edema, and posterior reversible encephalopathy syndrome, among others. Further investigation including head-to-head clinical trials is warranted to evaluate the efficacy of ozanimod compared with other S1P1 receptor modulators.

Multiple sclerosis (MS) is the most prevalent demyelinating condition of the central nervous system and produces significant disability over time. For many years it was considered to be an untreatable disease, but great advances have been made in the treatment of MS in the last 20 years. There are currently six US Food and Drug Administration (FDA)-approved disease-modifying agents for the relapsing form of the disease. We review in detail these medications and the pivotal trials leading to their approval. We will briefly review non-FDA-approved medications already used in MS. We will also discuss some of the medications currently being studied in phase II and III trials that are not yet approved for use in MS.
