Background: Multiple sclerosis (MS) is a chronic, typically progressive and most common autoimmune disease which damaged the central nervous system. According to the reports in 2008, this disorder has affected 2 and 2.5 million people globally. While the reason is not clear, proposed causes for this include immunologic, environmental, infectious and genetic factors, and sexuality. MS can cause many symptoms, including blurred vision, loss of balance, poor coordination, slurred speech, tremors, numbness, extreme fatigue, problems with memory and concentration, paralysis, blindness, and more. There are four distinguished illness fields in MS: relapsing-remitting MS (RRMS), primary–progressive MS (PPMS), secondary–progressive MS (SPMS), and progressive–relapsing. MRI is a great tool to identify the asymptomatic distribution of lesions in space and time.Materials and Methods: 32 patients with MS plaques were evaluated by FLAIR and DWI pre- and post-Gadolinium injection compared with 15minutes delay T1w SE.Results: FLAIR post-inject had significantly better detection of the number and signal intensity of active MS lesions. DWI and ADC images detected active plaques different from non-active lesions without contrast.Conclusion: The result of this study showed that FLAIR post-inject had the highest sensitivity in detection of active MS lesions due to the CSF signal suppression in FLAIR, thus offering enough TR time recovery in active enhanced plaques.

Multiple sclerosis (MS) is the most common neurologic demyelinating disease in high-income countries. The causes of MS is multifactorial involve genetics and the environment in which immune cell infiltration occurs across the blood-brain barrier, causing inflammation, demyelination, gliosis, and neuroaxonal degeneration in the substantia grisea in the central nervous system. A 23-year-old female patient was treated with four limbs weakened since 2 weeks ago accompanied by blurred vision, pain, cramps and stiffness in the back muscles and legs. The patient has experienced the same complaint before. Clinical findings reveal lhermitte sign, atrophy papillae, and tetraparese. On thoracic vertebral MRI examination without contrast and brain MRI with contrast obtained multiple sclerosis lesions. Patients receive steroid and antidepressant therapy. MS needs to be studied further because this number of cases began to emerge.

<p>Multiple sclerosis is an inflammatory demyelinating disorder of the central nervous system. Its presentation is variable and its course and prognosis are unpredictable. Approximately 85% of individuals present a relapsing-remitting form of the disease, but some patients may evolve into a progressive course, accumulating irreversible neurological disability, defining its secondary progressive phase. Despite all the advances that had been reached in terms of diagnosis, many decisions are still taken based only on pure clinical skills. We present the case of a patient that, after being diagnosed with a clinically isolated syndrome many years ago, seemed to be entering in a secondary progressive course, developing a clinical picture dominated by a progressive gait disturbance. Nevertheless, multiple sclerosis heterogeneity asks for some clinical expertise, in order to exclude all other possible causes for patients’ complaints. Here we present an important red flag in the differential diagnosis of secondary progressive multiple sclerosis.<br /><strong>Keywords:</strong> Magnetic Resonance Imaging; Multiple Sclerosis, Chronic Progressive; Meningioma.</p>

Background: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. MS lesions show a typical distribution pattern and primarily affect the white matter (WM) in the periventricular zone and in the centrum semiovale. Objective: To track lesion development during disease progression, we compared the spatiotemporal distribution patterns of lesions in relapsing–remitting MS (RRMS) and secondary progressive MS (SPMS). Methods: We used T1 and T2 weighted MR images of 209 RRMS and 62 SPMS patients acquired on two different 1.5 Tesla MR scanners in two clinical centers followed up for 25 (± 1.7) months. Both cross-sectional and longitudinal differences in lesion distribution between RRMS and SPMS patients were analyzed with lesion probability maps (LPMs) and permutation-based inference. Results: MS lesions clustered around the lateral ventricles and in the centrum semiovale. Cross-sectionally, compared to RRMS patients, the SPMS patients showed a significantly higher regional probability of T1 hypointense lesions ( p≤0.03) in the callosal body, the corticospinal tract, and other tracts adjacent to the lateral ventricles, but not of T2 lesions (peak probabilities were RRMS: T1 9%, T2 18%; SPMS: T1 21%, T2 27%). No longitudinal changes of regional T1 and T2 lesion volumes between baseline and follow-up scan were found. Conclusion: The results suggest a particular vulnerability to neurodegeneration during disease progression in a number of WM tracts.

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.

Abstract Tissue kallikrein KLK1 and the kallikrein-related peptidases KLK2–15 are a subfamily of serine proteases that have defined or proposed roles in a range of central nervous system (CNS) and non-CNS pathologies. To further understand their potential activity in multiple sclerosis (MS), serum levels of KLK1, 6, 7, 8 and 10 were determined in 35 MS patients and 62 controls by quantitative fluorometric ELISA. Serum levels were then correlated with Expanded Disability Status Scale (EDSS) scores determined at the time of serological sampling or at last clinical follow-up. Serum levels of KLK1 and KLK6 were elevated in MS patients (p≤0.027), with highest levels associated with secondary progressive disease. Elevated KLK1 correlated with higher EDSS scores at the time of serum draw and KLK6 with future EDSS worsening in relapsing remitting patients (p≤0.007). Supporting the concept that KLK1 and KLK6 promote degenerative events associated with progressive MS, exposure of murine cortical neurons to either kallikrein promoted rapid neurite retraction and neuron loss. These novel findings suggest that KLK1 and KLK6 may serve as serological markers of progressive MS and contribute directly to the development of neurological disability by promoting axonal injury and neuron cell death.

The presence of disability progression in multiple sclerosis (MS) is an important hallmark for MS patients in the course of their disease. The transition from relapsing remitting (RRMS) to secondary progressive forms of the disease (SPMS) represents a significant change in their quality of life and perception of the disease. It could also be a therapeutic key for opportunities, where approaches different from those in the initial phases of the disease can be adopted. The characterization of structural biomarkers (e.g., magnetic resonance imaging or neurofilament light chain) has been proposed to differentiate between both phenotypes. However, there is no definite threshold between them. Whether the risk of clinical progression can be predicted by structural markers at early disease phases is still a focus of clinical research. However, several theories and pathological evidence suggest that both disease phenotypes are part of a continuum with common pathophysiological mechanisms. In this case, the clinical evaluation of the patients would play a preponderant role above destruction biomarkers for the early identification of disability progression and SPMS. For this purpose, the use of clinical tools beyond the Expanded Disability Status Scale (EDSS) should be considered. Besides established functional tests such as the Multiple Sclerosis Functional Composite (MSFC), patient's neurological history or digital resources may help neurologists in the decision-taking. In this article, we discuss arguments for the use of clinical markers in the detection of secondary progressive MS and the characterization of progressive disease activity.

Chemokines and their receptors are important in the trafficking of peripheral leukocytes into the central nervous system, a major event in the pathogenesis of multiple sclerosis (MS). Evidence based on clinical, pathological and magnetic resonance imaging grounds supports some divergence between forms of MS with relapses [relapsing-remitting (RR) and secondary progressive (SP)] and the primary progressive (PP) form. To elucidate whether different pathogenic mechanisms are involved in PPMS, we compared membrane expression of a group of CC and CXC chemokine receptors (CCR1, CCR5, CXCR3, CXCR4) in peripheral blood of 68 MS patients (25 PPMS, 23 SPMS and 20 RRMS) and 26 healthy controls. We found a significant increase in surface expression of CCR5 in CD4+, CD8+, CD19+ and CD14+ cells as well as an increased percentage of CXCR3 and CXCR4 in CD14+ cells in MS patients compared to controls. Increased levels of CXCL10 (IP-10) and CCL5 (RANTES) in cerebrospinal fluid were also observed in a subgroup of MS patients. These results support that chemokines and their receptors are involved in the pathogenesis of MS. However, a pattern of chemokine-chemokine receptor expression characteristic of each clinical form of the disease failed to be observed.

Background Disease-modifying therapies are thought to reduce the conversion rate to secondary progressive multiple sclerosis. Objective To explore the rate, chronology, and contributing factors of conversion to the progressive phase in treated relapsing–remitting multiple sclerosis patients. Methods Our study included 204 patients treated for relapsing–remitting multiple sclerosis between 1995 and 2002, prospectively followed to date. Kaplan–Meier analysis was applied to estimate the time until secondary progressive multiple sclerosis conversion, and multivariate survival analysis with a Cox regression model was used to analyse prognostic factors. Results Relapsing–remitting multiple sclerosis patients were continuously treated for 13 years (SD 4.5); 36.3% converted to secondary progressive multiple sclerosis at a mean age of 42.6 years (SD 10.6), a mean time of 8.2 years (SD 5.2) and an estimated mean time of 17.2 years (range 17.1–18.1). A multifocal relapse, age older than 34 years at disease onset and treatment failure independently predicted conversion to secondary progressive multiple sclerosis but did not influence the time to reach an Expanded Disability Status Scale of 6.0. Conclusions The favourable influence of disease-modifying therapies on long-term disability in relapsing–remitting multiple sclerosis is well established. However, the time to progression onset and the subsequent clinical course in treated patients seem similar to those previously reported in natural history studies. More studies are needed to clarify the effect of disease-modifying therapies once the progressive phase has been reached.

Multiple sclerosis (MS), an inflammatory demyelinating disease of the central nervous system, typically affects young to middle-aged adults. Women are affected nearly three times as often as men. The diagnosis requires the demonstration of dissemination in space (DIS) and time (DIT) in a patient with no better clinical explanation. Evidence for either DIS or DIT or both may now be obtained from MRI, in addition to clinical manifestations. The most widely used diagnostic criteria are known as the McDonald criteria, and have been revised several times, most recently in 2017. In the current criteria, DIS may be achieved by the demonstration of at least one lesion in at least two different locations: periventricular, cortical/juxtacortical, infratentorial, or spinal cord. DIT may be considered in an initial magnetic resonance imaging (MRI) if there are simultaneously at least one gadolinium-enhancing lesion and one non-enhancing T2 hyperintense lesion; or alternatively, by the demonstration of a new lesion on any MRI subsequent to the first. The course of MS is characterized as relapsing-remitting (RRMS), secondary progressive, or primary progressive. Many effective disease-modifying agents are available for RRMS, but progressive forms have been much less successfully treated.
