Introduction
Multiple sclerosis (MS) is the commonest non-traumatic disabling disease to a?ect young adults [1]. There is increasing incidence and prevalence of MS in both developed and developing countries [2], the underlying cause of which remain’s uncertain. MS is a complex disease; many genes modestly increase disease susceptibility in addition to several well de?ned environmental factors, in particular vitamin D or ultraviolet B light (UVB) exposure, Epstein–Barr virus (EBV) infection, obesity and smoking [3].
Multiple sclerosis has historically been classi?ed as an organ-speci?c T-cell mediated autoimmune disease. However, the success of B-cell targeted therapies challenges the standard T-cell autoimmune dogma [4]. It is traditionally viewed as a two-stage disease, with early in?ammation responsible for relapsing–remitting disease and delayed neuro degeneration causing non- relapsing progression, i.e. secondary and primary progressive MS [5, 6].
The emergence of increasingly e?ective biological therapies and an active approach to treating MS, in particular treating to a target of no evident disease activity (NEDA), are changing the long-term outcome for people with MS (pwMS). More aggressive immune reconstitution therapies, that result in a proportion of pwMS entering long-term remission, o?er a small number of pwMS a potential cure [7]. Recent positive trials of disease-modifying therapies in progressive MS o?er those with more advanced MS the hope of slowing their disease progression, with preservation of residual function [8]. The fact that treatments appear to work at multiple stages in the disease course signi?cantly challenges the traditional two-stage view of the natural history of MS [9].
Justification:
Young adults are most important to change the world. They play an important role in every sphere of development. In our adult-run world, youth aren’t often asked for their opinions and ideas on how to address society’s greatest challenges. Yet a collective effort to reverse this trend is one of the most powerful steps we can take towards a tangibly better world.
Multiple sclerosis (MS) is the commonest non-traumatic disabling disease to a?ect young adults. The incidence of MS is increasing worldwide, togetherwith the socioeconomic impact of the disease. The underlying cause of MS and mechanisms behind this increase remain opaque, although complex gene–environment interactions almost certainly play a signi?cant role.
Most patients are diagnosed during early adult life, and women have a markedly higher incidence. Overall, there is evidence for MS onset being triggered by environmental factors in genetically predisposed individuals, such as low vitamin D levels, cigarette smoking and obesity in early life [1]. Approximately 85–95% of the patients present a relapsing–remitting course (RRMS), characterized by relapsing phases intertwined with periods of neurological stability [2, 3].
Multiple sclerosis (MS) is an immune-driven neurological disease that has a profound impact on patients’ quality of life (QOL). MS affects approximately 2.3 million people worldwide, and its prevalence is remarkably heterogeneous, varying from 50 to 300 patients per 100 000 inhabitants [1].
However, MS can also assume a progressive course, characterized by a steadily increasing neurological decline, either from the onset (primary progressive MS [PPMS]), or within 15–25 years of RRMS diagnosis (secondary progressive MS [SPMS]) [2, 3]. The MS diagnosis remains challenging and relies on the integration of clinical, laboratory and imaging findings, with the McDonald criteria being used by most neurologists [2].
The aims of the study were to assess the prevalence of Multiple Sclerosis among young adults and from this study, awareness will be increased and may provide proper recommendation for every single risk which will be helpful for young adults. For this reason one study is necessary to conduct on to take the preventive measures and minimized the gap of the knowledge on this regard. For further research it will also open large avenue and the result of the study may help health care provider as well as adults to take proper management. That is why conducting this study is necessity of the time for the young adults
Literature Review:
Multiple sclerosis (MS) is a chronic, inflammatory disease of the central nervous system, affecting mostly young adults and possibly leading to irreversible physical, psychical and cognitive disability with a negative impact on quality of life and productivity of patients. After traumatic injury, it is the second most common cause of permanent disability in young adults [1].
According to worldwide estimates of the Multiple Sclerosis International Federation and the World Health Organization published in Atlas of MS 2013 [2, 3], it affects 2.3 million individuals worldwide and around 690,000 in Europe. The Atlas also states that substantial inequalities exist among regions and countries regarding the access to neurological care, magnetic resonance imaging and disease-modifying treatment.
In MS Barometer 2015 [4], published by European Multiple Sclerosis Platform, these inequalities were confirmed even among European countries and also it was underlined that only between 0–75% of MS-patients work in full-time job and only 0–50% of MS-patient have part-time employment (depending on the country). Continuous treatment and complex management of MS is a burden for the health care system and caregivers as well [5, 6] and in the era of upcoming expensive immunomodulatory drugs, optimal allocation and planning of healthcare resources require accurate data on the number of patients affected by the disease.
It is often stated that the cause of MS is unknown; however, this is not quite correct. EBV, sunshine (UVB), smoking and vitamin D, combined with an individual’s genetic background, play important roles in the causal pathway that results in MS development [10]. Migration studies consistently support MS being secondary to an environmental exposure [11]. Adult migrants from low risk countries, such as the West Indies, to Europe are at low risk of developing MS; however, children born to migrants in Europe are at high risk. Migration studies indicate that environment trumps genetics and argue strongly for prevention studies targeting known environmental risk factors.
Being truly EBV negative protects from developing MS [12, 13]; symptomatic EBV infection (i.e. infectious mononucleosis) doubles the chances of getting MS [14]. Evidence regarding the mechanism via which EBV increases MS risk is heterogeneous; molecular mimicry is historically a popular theory [15]. More recently EBV-induced B-cell immortalization and/or transformation has been thought to play an important role in disease development [16]. Multiple sclerosis is increasingly a global disease [2].
MS prevalence increases with latitude; however, this gradient is decreasing in Norway and the USA, the two countries where it has been studied [17]. The latitudinal gradient in MS prevalence is strongly correlated with UVB exposure, which stimulates cutaneous vitamin D (vD) production. Low vD levels, decreased intake of vD, reduced outdoor activity and increased MS susceptibility associated with genetic polymorphisms causing low vD levels have implicated vD in the causal pathway of MS [18].
Multiple sclerosis is more common in females, but this has not always been the case. In case series from the early 1900s the sex ratio was almost equal. Since then, the sex ratio has steadily been increasing and it is now close to 3:1 (F:M) in most developed countries [19]. Smoking, which increases MS risk by approximately 50%, can explain up to 40% of the increased incidence of MS in women [20]. Prior to the Second World War, few women smoked, but the number of women smoking rapidly increased post-war, mirroring the increasing incidence of MS in women [20]. The observation that organic solvents [21] and smoked tobacco [22], but not oral tobacco or snu? [23], are associated with MS has led to the hypothesis that these agents cause post-translational modi?cations via antigen presentation occurring in the lungs.
It is likely that MS risk modi?cation occurs throughout life, starting in utero [10]. The month-of-
birth e?ect and increased concordance in dizygotic twins compared to siblings indicates that the intrauterine environment is important in establishing MS risk; it is unclear whether this is due to common environmental exposures, or epigenetic mechanisms, or both [10]. There is a genetic in?uence on MS susceptibility; about one in eight patients have a family history of MS [24]. Concordance in female monozygotic twins approaches 30% in the UK and Canada, but is as low as 8.5% in southern Europe [25].
Genome-wide association studies have identi?ed more than 150 single nucleotide polymorphisms associated with MS susceptibility [28]. The odds ratio associated with the majority of these is small, around 1.1–1.2. Many of these single nucleotide polymorphism’s lie close to genes associated with immune function, typically in regulatory rather than coding regions. Functional variants identi?ed include those within IL7R [29], IL2RA [30], TNFR1 [31], BAFF [32] and CYP2R1 [33].
Mendelian randomization studies have provided evidence for a role of vitamin D [33–35] and obesity [36] as independent risk factors causing disease. Recent work has uncovered genetic di?erences between relapsing– remitting MS (RRMS) and primary progressive MS (PPMS) [37] not previously detected in genome-wide association studies, most probably due to the under-representation of PPMS in these cohorts. Genetic variants associated with other progressive neurological disorders are relatively over-represented in progressive MS [37]. Similar genetic risk exists when all MS-associated alleles are taken into account, indicating additional risk for progressive disease superimposed on underlying genetic susceptibility. Evidence of di?erential gene transcription between RRMS and PPMS [38] again hints at individual di?erence’s on a background of shared genetic risk.
