Abstract
Multiple sclerosis (MS) is a chronic autoimmune disease that impacts the central nervous system and can result in disability. Although the prevalence of MS has increased in India, diagnosis and treatment continue to be difficult due to several factors. The present study examines the difficulties in detecting and treating multiple sclerosis in India. A lack of MS knowledge among healthcare professionals and the general public, which delays diagnosis and treatment, is one of the significant issues. Inadequate numbers of neurologists and professionals with knowledge of MS management also exacerbate the situation. In addition, MS medications are expensive and not covered by insurance, making them inaccessible to most patients. Due to the absence of established treatment protocols and standards for MS care, India's treatment techniques vary. In addition, India's population diversity poses unique challenges regarding genetic variations, cellular and molecular abnormalities, and the potential for differing treatment responses. MS is more difficult to accurately diagnose and monitor due to a lack of specialized medical supplies and diagnostic instruments. Improved awareness and education among healthcare professionals and the general public, as well as the development of standardized treatment regimens and increased investment in MS research and infrastructure, are required to address these issues. By addressing these issues, it is anticipated that MS diagnosis and treatment in India will improve, leading to better outcomes for those affected by this chronic condition.

Abstract
Autoimmune disorders (AIDs) are known to be associated with intracranial aneurysms; however, the coexistence of dual AIDs is a rare entity. Perioperative neuroanesthetic management of aneurysmal subarachnoid hemorrhage (aSAH) is typically complicated and challenging in such patients. In this report, we describe the successful management of a case of aSAH complicated by coexistent multiple sclerosis and systemic lupus erythematosus. A multidisciplinary team approach is warranted to manage such complicated cases.

Abstract
BACKGROUND Many potential causes of optic nerve inflammation exist, including typical and atypical causes, which require different management strategies. OBJECTIVE The objective of this study is to identify red flags that help differentiate typical from atypical optic neuritis (ON). MATERIALS AND METHODS This prospective study included 66 patients (100 eyes) with immune-mediated ON from January 2016 to June 2019, carefully excluding the nonimmune causes. The clinico-radiological features, investigations, therapy, and outcome were analyzed. RESULTS We evaluated 33 cases each of typical and atypical ON. The typical group included 29 idiopathic ON and four associated with multiple sclerosis. Atypical ON included 19 neuromyelitis optica (NMO), seven MOG-associated ON (MOG-ON), and others due to Sjogren's syndrome, granulomatous polyangiitis, sarcoidosis, and IgG4 disease. Atypical ON occurred significantly and more frequently with extremes of ages (<10 or >70 years), bilateral simultaneous or severe vision loss with early disc pallor, multiple attacks, symptoms/neuro-imaging indicating non-MS disease e.g., long segment ON/myelitis, large confluent lesions, the involvement of optic tract, chiasma, area postrema or diencephalon, and (pachy) meningitis. Systemic involvement and poor outcomes despite steroids and second-line immunosuppression were observed more often in the atypical ON. CONCLUSIONS The red flags indicating atypical ON are onset at extremes of age, multiple attacks, bilateral simultaneous or severe to very severe vision loss, early disc pallor, neurological symptoms, or imaging abnormalities suggesting non-MS disease, systemic involvement, and poor steroid responsiveness. The awareness might help the clinician promptly identify and escalate therapy to ensure a better outcome.

Abstract
Introduction
An inflammatory lesion of the spinal cord where three or more than three vertebral segments of the cord is involved is called longitudinal extensive myelitis (LETM). It has several varied causes out of which neuromyelitis optica (NMO) and its spectrum disorder have received a distinct entity. Various radiological and clinical features help us to suspect an etiology which then further guides us into the treatment protocol and prognosis of the patients.
Materials and Methods
A retrospective study performed in a referral center in North East India in 15 months. Thirty-two patients of LETM were enrolled based on clinical and radiological available data. An attempt was made to classify the various etiologies and correlate with their radiological findings.
Results
The most common etiology noted was NMO seen in 7 patients (21.8%) followed by tuberculosis (TB) (18.7%) and post-infection myelitis (18.7%). Other etiology seen was acute disseminated encephalomyelitis (6.24%), spinal cord infarct (3.12%), radiation myelitis (6.24%), Japanese encephalitis sequalae (3.12%), systemic lupus erythematosus (3.12%), and remained undiagnosed in six patients (18.7%). Radiologically, cervico-dorsal spine was most common location in NMO (71%) whereas dorsolumbar in TB (50%). The lesion was predominantly central in both NMO (100%) and TB (80%) as compared with the other causes of LETM. It was noted that more than 50% of the transverse area of the cord was involved in both NMO (71%) and TB (50%), but < 50% involvement were more common in the post-infectious and others causes of LETM.
Conclusion
LETM has a various differential diagnosis, infection need to be kept in mind while ruling out NMO. Radiological features can suggest or help differentiate the various etiologies of LETM but NMO and infection like TB almost has the same features except for a different cord site predilection.

Abstract
BACKGROUND Different human leukocyte antigen (HLA) variants are known to modulate the risk of multiple sclerosis. The main objective of this study was to identify HLA-DRB1 and HLA-DQB1 alleles and Non -HLA gene IL7R (rs6897932) variants associated with MS. METHODS Patients attending the MS clinic, diagnosed with Multiple Sclerosis as per Mc Donald diagnostic criteria were the subjects in the study. The association of the highly polymorphic HLA-DRB1 and HLA-DQB1 loci was determined by high resolution tissue typing and the genotyping of the IL7R (rs6897932) variants was performed by Sanger sequencing in MS patients (n = 81) and healthy individuals (n = 82). RESULTS HLA-DRB1*15:01/15:02 alleles (OR = 3.65; p< 0.0001) and HLA-DQB1*06:02 (OR=4.19, p<0.0001) were found to be positively associated while HLA-DRB1*14:04:01 (OR = 0.21; p = 0.0009) was found to be negatively associated with MS. The most significant predisposing HLA haplotype was found to be DRB1*15:01-DQB1*06:02 (OR=5.69, p<0.0001). Univariate analysis of IL7R SNP (rs6897932) showed no significant association with MS in our population whereas analysis of HLA-DRB1 alleles and IL7R (rs6897932) genotypes showed significant association between the HLA-DRB1*15:01/15:02 and the IL7R (rs6897932) CC genotype (OR = 3.58, p = 0.0002). CONCLUSION HLA-DRB1*15:01, 15:02 and DQB1*06:02 are the predisposing alleles while HLA-DRB1*14:04 is the protective allele for MS in our population.

Abstract
Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) which commonly leads to disability. We reviewed articles on MS from Pakistan using PubMed, Google Scholar and Pak Medinet to present different aspects of the disease and the status of disease modifying treatments in Pakistan and South Asia. MS is not as uncommon in Pakistan as it has been previously thought to be. Estimated prevalence of MS in Pakistan may be 10 per 100,000 population. Data suggests that most features of MS found in Pakistan are similar to those found in the West. These features include a female preponderance, mean age of onset in the third decade of life and similar risk factors including viral infections, smoking, and vitamin D deficiency, as well as genetic risk factors. Relapsing-remitting multiple sclerosis (RRMS) is the most common disease pattern seen in Pakistan which is also consistent with data from other regions. Treatment modalities in Pakistan include immunomodulatory and immunosuppressive drugs. In order to improve care for MS patients in Pakistan, it is extremely important to obtain a population-based prevalence of MS in the country and a national MS registry, along with implementing programs for patients' awareness and the training of doctors, especially internists. There are many disease modifying therapies (DMT) available in Pakistan but no data is available on the utilization and impact of these DMTs.

Abstract
Multiple sclerosis (MS) is a chronic neurological disease which often leads to disability. The complex etiology and progressive nature pose challenges in the management of patients with MS, particularly in developing countries like India. Lack of data on prevalence further complicates estimation of the magnitude of MS in India. There are various other challenges associated with management of patients with MS due to which the therapy is utilized by only a small segment of population in India. This article encapsulates the gaps and challenges in the management of patients with MS and presents suggestions and recommendations of the members of advisory boards held to discuss these challenges. The advisory board members suggested that an early diagnosis of MS and an early initiation of treatment are essential to achieve better results for tackling MS-related challenges. In addition, awareness and education about MS among people, regular training to physicians, emphasis on the use of revised 2010 McDonald criteria, and utilization of advanced diagnostic modalities in magnetic resonance imaging would help to achieve desirable as well as effective therapeutic outcomes. Further, access to an easy-to-use therapy delivery system could also be beneficial in attaining an adequate treatment adherence and related health benefits.

Abstract
Multiple sclerosis (MS) is a demyelinating disease of the central nervous system causing axonal injury, neuronal loss, and atrophy of the central nervous system leading to permanent neurological and clinical disability. Presence of mutations in M9 domain of HNRNPA1 and detection of autoantibodies against this domain in HNRNPA1 qualifies it as a strong candidate for causing MS. These two aspects indicate the presence of a facilitator in associating them. Varicella zoster virus (VZV), known to cause chicken pox infection in humans, is a significant contender in sensitizing the infected people towards MS. Reactivation of latent herpes viruses by other infectious agents and cross-recognition of common viral antigens with antigens found in the myelin sheath induces molecular mimicry or superantigens. Mutations in HNRNPA1 cause mislocalization to the cytoplasm, and co-localize with stress granules (SG) causing cellular apoptosis, this creates the first step toward MS pathogenesis. Mutant HNRNPA1 accumulates in SG allowing the cells to display peptides of HNRNPA1 on surfaces of major histocompatibility complex (MHC) I triggering a cascade of immune reactions. Since glycoprotein E (gE) of VZV shares >62% amino acids sequence similarity with Prion-like domain (PrLD) of HNRNPA1, signifying the reason behind autoantibodies against M9 and PrLD of HNRNPA1. This review attempts to delineate the interactions of VZV, gE of VZV, with M9 domain and PrLD of HNRNPA1 in a step-by-step process. This supports the tripartite model that an environmental trigger in genetically susceptible individuals causes an autoimmune response to self-CNS antigens that result in the pathology observed in the brain and spinal cord of MS patients.

Abstract
Multiple sclerosis (MS) is a neurodegenerative disease in which myelin sheath damage occurs due to internal and external factors. MS especially affects the young population. Dimethyl fumarate (DMF) is a promising agent for MS treatment, although it is associated with concerns such as poor brain permeation, multiple dosing, and gastrointestinal flushing. The present study attempts to evaluate the preclinical performance of specially designed DMF-based lipoidal nanoparticles in a cuprizone-induced demyelination model in rodents. The studies proved the efficacy of lipid-based nanoparticles containing DMF in a once-a-day dosage regimen over that of thrice-a-day plain DMF administration on crucial parameters like motor coordination, grip strength, mortality, body weight, and locomotor activity. However, neither blank lipid nor blank neuroprotective (vitamins A, D, and E) loaded nanoparticles were able to elicit any desirable behavioral response. Histopathological studies showed that the designed once-a-day DMF nanomedicines were well tolerated and rejuvenated the myelin sheath vis-à-vis the plain DMF thrice-a-day regimen. These findings provide proof of concept for a biocompatible nanomedicine for MS with tremendous promise for effective brain delivery and patient compliance on the grounds of a reduction in the dosage frequency.

Abstract
OBJECTIVES To identify Damaging mutations in microRNAs (miRNAs) and 3' untranslated regions (UTRs) of target genes to establish Multiple sclerosis (MS) disease pathway. METHODS Female aged 16, with Relapsing Remitting Multiple sclerosis (RRMS) was reported with initial symptoms of blurred vision, severe immobility, upper and lower limb numbness and backache. Whole Exome Sequencing (WES) and disease pathway analysis was performed to identify mutations in miRNAs and UTRs. RESULTS We identified Deleterious/Damaging multibase mutations in MIR8485 and NRXN1. miR-8485 was found carrying frameshift homozygous deletion of bases CA, while NRXN1 was found carrying nonframeshift homozygous substitution of bases CT to TC in exon 8 replacing Serine with Leucine. CONCLUSIONS Mutations in miR-8485 and NRXN1 was found to alter calcium homeostasis and NRXN1/NLGN1 cell adhesion molecule binding affinities. The miR-8485 mutation leads to overexpression of NRXN1 altering pre-synaptic Ca2+ homeostasis, inducing neurodegeneration.
