    Multiple sclerosis (MS) is a chronic, debilitating disease that can have devastating effects. Presentation varies widely in symptoms, pace, and progression. In addition to a thorough history and physical examination, diagnostic tools required to diagnose MS and exclude other diagnoses include MRI, evoked potential testing, and cerebrospinal fluid analysis. Although the disease is not curable presently, quality of life can be improved by minimizing the frequency and severity of disease burden. Disease modification, symptom management, preservation of function, and treatment of psychosocial issues are paramount to enhance the quality of life for the patient affected with MS.

    Multiple sclerosis can affect vision in many ways, including optic neuritis, chronic optic neuropathy, retrochiasmal visual field defects, higher order cortical processing, double vision, nystagmus and also by related ocular conditions such as uveitis. There are also side effects from recently introduced multiple sclerosis treatments that can affect vision. This review will discuss all these aspects and how they come together to cause visual symptoms. It will then focus on practical aspects of how to recognise when there is a vision problem in a multiple sclerosis patient and on what treatments are available to improve vision.

    Amyotrophic lateral sclerosis is one of the most severe and disabling diseases of the nervous system. Amyotrophic lateral sclerosis leads to the progressive weakening of the muscles in the arms, legs, face, mouth and trunk. The onset of the disease is insidious, starting with weakness in the hands or feet or with slurred speech. The weakness worsens and patients pass away as a result of weakness of the respiratory muscles on average within 3 years of the onset of the disease. In the Netherlands, approximately 400 patients are diagnosed with amyotrophic lateral sclerosis every year. There is no diagnostic test for this neuro-muscular disease; the diagnosis is established by excluding other disorders that resemble amyotrophic lateral sclerosis. Only one drug is able to inhibit the progression of the disease to any extent: riluzole. Treatment, therefore, is mainly focused on supportive measures and those which enhance the quality of life optimally.

    Multiple sclerosis is one of the main reasons for invalidation of young adults of both sexes. The disease is more common in women than in men. The illness begins most frequently in patients between the ages of 20 and 40 years, which is also the most fertile period for women. MS is an immune-mediated disease with chronic evolution marked by exacerbations and remissions that amplify the degree of disability. The most common clinical picture is the one with relapse and remission whose evolution is greatly improved after immunomodulatory treatment. We have revised the literature together with the data from the national multiple sclerosis society and the cases that are in the National Programme of Multiple Sclerosis, mainly the ones that are assigned to the regional center of Iaşi, at the Neurology Clinic inside the Clinical Rehabilitation Hospital Iaşi. Pregnancy is quite frequent in female patients with MS. Certain risks are present during pregnancy, birth and breastfeeding and certain protocols must be applied, such as interrupting the immunomodulatory treatment before the conception. Child delivery must be closely monitored and it must take into consideration the dysfunction that the patient has and be adapted to the existing deficits. There are some methods that may be used during delivery for female patients with multiple sclerosis in order to make this process smooth and reduce the risk of postpartum complications. Multiple sclerosis is an invalidating disease, with a high prevalence in women. Pregnancy in patients with MS is not such a natural phenomenon as in a healthy female and it requires a multidisciplinary team in order to ensure the safety of both the mother and the newborn.

A case of hypercalcaemia and parathyroid adenoma in association with tuberous sclerosis is presented, of which there has been one such report published previously. This association might be another manifestation of this complex disease: it is therefore recommended that plasma calcium concentrations should be measured in such patients. PMID:1752991

    Multiple sclerosis occurs in genetically susceptible individuals, in whom an unknown environmental factor triggers an immune response, giving rise to a chronic and disabling autoimmune disease. Currently, significant progress is being made in our knowledge of the frequency and distribution of multiple sclerosis and its risk factors, genetics, pathology, pathogenesis, diagnostic and prognostic markers, and treatment. This has radically changed patients' and clinicians' expectations of multiple sclerosis and has raised hope that there will soon be a way to control the disease.

    2015-01-01

    We performed a literature search regarding the safety and efficacy of electroconvulsive therapy in patients with multiple sclerosis and comorbid psychiatric symptoms. Literature review was conducted via PubMed databases. Of the cases we reviewed, most subjects with multiple sclerosis reported significant psychiatric symptom relief, with only a handful reporting neurologic deterioration. There was some evidence that active white matter lesions may be predictive of neurologic deterioration when electroconvulsive therapy is used in patients with multiple sclerosis. A brief description of the pathophysiology and effects of depression in patients with multiple sclerosis is also provided. Although no clinical recommendations or meaningful conclusions can be drawn without further investigation, the literature suggests that electroconvulsive therapy for treatment of psychiatric illnesses in patients with multiple sclerosis is safe and efficacious.

    Walking impairment is a common consequence of multiple sclerosis (MS) that can result in substantial limitations of daily activities and compromised quality of life. Walking impairment is often monitored as an indicator of disease and neurologic disability progression. The worsening of walking performance while undertaking a cognitive task underscores the role of nonmotor impairments in ambulation limitations. Walking impairment has ubiquitous and life-altering consequences, underscoring the importance of continued efforts to identify approaches to prevent and forestall this event, and to restore walking ability in persons with MS.

    2015-12-01

    Autonomic dysfunction is a prevalent and significant cause of disability among patients with multiple sclerosis. Autonomic dysfunction in multiple sclerosis is usually explained by lesions within central nervous system regions responsible for autonomic regulation, but novel evidence suggests that other factors may be involved as well. Additionally, the interactions between the autonomic nervous system and the immune system have generated increased interest about the role of autonomic dysfunction in the pathogenesis of multiple sclerosis. In this paper we analyze systematically the most relevant signs and symptoms of autonomic dysfunction in MS, considering separately their potential causes and implications.

    Amyotrophic lateral sclerosis is a neurodegenerative disease predominantly affecting upper and lower motor neurons, resulting in progressive paralysis and death from respiratory failure within 2 to 3 years. The peak age of onset is 55 to 70 years, with a male predominance. The causes of amyotrophic lateral sclerosis are only partly known, but they include some environmental risk factors as well as several genes that have been identified as harbouring disease-associated variation. Here we review the nature, epidemiology, genetic associations, and environmental exposures associated with amyotrophic lateral sclerosis.

    Tuberous sclerosis is an inherited neurocutaneous disorder that occurs in approximately 1 in 7,500 live births. It is characterized by benign neoplasms of the skin, heart, kidneys, lungs, central nervous system, and mucosa. Oral lesions are usually fibrous in nature and most commonly occur on the anterior gingivae. Patients may suffer with epilepsy and learning difficulties, which may complicate dental management. When a 10-year-old girl with a history of tuberous sclerosis was brought in for a routine dental check-up, a leafy growth on the anterior gingiva was detected. An excisional biopsy was carried out. Histologically, the appearance was described as nonspecific, but was consistent with a diagnosis of tuberous sclerosis. Tuberous sclerosis is a rare condition that may exhibit oral manifestations. The patients may also exhibit epilepsy and learning difficulties. Dental management of affected patients may therefore be more complicated and complex.

    2007-01-01

    Tremor is estimated to occur in about 25 to 60 percent of patients with multiple sclerosis (MS). This symptom, which can be severely disabling and embarrassing for patients, is difficult to manage. Isoniazid in high doses, carbamazepine, propranolol and gluthetimide have been reported to provide some relief, but published evidence of effectiveness is very limited. Most trials were of small size and of short duration. Cannabinoids appear ineffective. Tremor reduction can be obtained with stereotactic thalamotomy or thalamic stimulation. However, the studies were small and information on long-term functional outcome is scarce. Physiotherapy, tremor reducing orthoses, and limb cooling can achieve some functional improvement. Tremor in MS remains a significant challenge and unmet need, requiring further basic and clinical research. PMID:17318714

    Proper classification of patients into diffuse cutaneous and limited cutaneous subsets and the anticipation of complications are the keys to the management of subjects with systemic sclerosis (scleroderma). Patients with early diffuse disease and rapidly progressive skin thickening are at highest risk of developing serious disease of the internal organs (intestine, lung, heart, kidney) and should be considered for disease modifying treatment. The targets of the disease and sites of possible intervention are vascular endothelium (vasoprotective agents), mononuclear cell subsets (immunosuppressive agents), and fibroblasts (colchicine, D-penicillamine). A number of new agents with sound scientific rationale are currently undergoing therapeutic trials. Much can be done to improve the lifestyle of those with scleroderma. The most dramatic recent development is the ability to reverse kidney disease by the prompt use of angiotensin converting enzyme inhibitors and modern methods of renal dialysis and transplantation. Scleroderma is not a hopeless disease. PMID:1750801

    2010-01-01

    Tuberous sclerosis complex (TSC) is an autosomal dominant disorder that results from mutations in the TSC1 or TSC2 genes and is associated with hamartoma formation in multiple organ systems. The neurological manifestations of TSC are particularly challenging and include infantile spasms, intractable epilepsy, cognitive disabilities, and autism. Progress over the past 15 years has demonstrated that the TSC1 or TSC2 encoded proteins modulate cell function via the mTOR signaling cascade and serve as keystones in regulating cell growth and proliferation. The mTOR pathway provides an intersection for an intricate network of protein cascades that respond to cellular nutrition, energy levels, and growth-factor stimulation. In the brain, TSC1 and TSC2 have been implicated in cell body size, dendritic arborization, axonal outgrowth and targeting, neuronal migration, cortical lamination, and spine formation. Antagonism of the mTOR pathway with rapamycin and related compounds may provide new therapeutic options for TSC patients. PMID:20146692

  15. Vaccines in Multiple Sclerosis.

    PubMed

    Williamson, Eric M L; Chahin, Salim; Berger, Joseph R

    2016-04-01

    Vaccinations help prevent communicable disease. To be valuable, a vaccine's ability to prevent disease must exceed the risk of adverse effects from administration. Many vaccines present no risk of infection as they are comprised of killed or non-infectious components while other vaccines consist of live attenuated microorganisms which carry a potential risk of infection-particularly, in patients with compromised immunity. There are several unique considerations with respect to vaccination in the multiple sclerosis (MS) population. First, there has been concern that vaccination may trigger or aggravate the disease. Second, disease-modifying therapies (DMTs) employed in the treatment of MS may increase the risk of infectious complications from vaccines or alter their efficacy. Lastly, in some cases, vaccination strategies may be part of the treatment paradigm in attempts to avoid complications of therapy.

    PubMed Central

    Statland, Jeffrey M.; Barohn, Richard J.; Dimachkie, Mazen M.; Floeter, Mary Kay; Mitsumoto, Hiroshi

    2015-01-01

    Synopsis Primary lateral sclerosis (PLS) is characterized by insidious onset of progressive upper motor neuron dysfunction in the absence of clinical signs of lower motor neuron involvement. Patients experience stiffness, decreased balance and coordination, and mild weakness, and if the bulbar region is affected, difficulty speaking and swallowing, and emotional lability. The diagnosis is made based on clinical history, typical exam findings, and diagnostic testing negative for other causes of upper motor neuron dysfunction. EMG is normal, or only shows mild neurogenic findings in a few muscles, not meeting El Escorial criteria. Although no test is specific for PLS, some neurodiagnostic tests are supportive: including absent or delayed central motor conduction times; and changes in the precentral gyrus or corticospinal tracts on MRI, DTI or MR Spectroscopy. Treatment is largely supportive, and includes medications for spasticity, baclofen pump, and treatment for pseudobulbar affect. The prognosis in PLS is more benign than ALS, making this a useful diagnostic category. PMID:26515619

  17. Therapeutics for multiple sclerosis symptoms.

    PubMed

    Ben-Zacharia, Aliza Bitton

    2011-01-01

    Symptoms management in multiple sclerosis is an integral part of its care. Accurate assessment and addressing the different symptoms provides increased quality of life among patients with multiple sclerosis. Multiple sclerosis symptoms may be identified as primary, secondary, or tertiary symptoms. Primary symptoms, such as weakness, sensory loss, and ataxia, are directly related to demyelination and axonal loss. Secondary symptoms, such as urinary tract infections as a result of urinary retention, are a result of the primary symptoms. Tertiary symptoms, such as reactive depression or social isolation, are a result of the social and psychological consequences of the disease. Common multiple sclerosis symptoms include fatigue and weakness; decreased balance, spasticity and gait problems; depression and cognitive issues; bladder, bowel, and sexual deficits; visual and sensory loss; and neuropathic pain. Less-common symptoms include dysarthria and dysphagia, vertigo, and tremors. Rare symptoms in multiple sclerosis include seizures, hearing loss, and paralysis. Symptom management includes nonpharmacological methods, such as rehabilitation and psychosocial support, and pharmacological methods, ie, medications and surgical procedures. The keys to symptom management are awareness, knowledge, and coordination of care. Symptoms have to be recognized and management needs to be individualized. Multiple sclerosis therapeutics include nonpharmacological strategies that consist of lifestyle modifications, rehabilitation, social support, counseling, and pharmacological agents or surgical procedures. The goal is vigilant management to improve quality of life and promote realistic expectations and hope.

  3. Optineurin and amyotrophic lateral sclerosis.

    PubMed

    Maruyama, Hirofumi; Kawakami, Hideshi

    2013-07-01

    Amyotrophic lateral sclerosis is a devastating disease, and thus it is important to identify the causative gene and resolve the mechanism of the disease. We identified optineurin as a causative gene for amyotrophic lateral sclerosis. We found three types of mutations: a homozygous deletion of exon 5, a homozygous Q398X nonsense mutation and a heterozygous E478G missense mutation within its ubiquitin-binding domain. Optineurin negatively regulates the tumor necrosis factor-α-induced activation of nuclear factor kappa B. Nonsense and missense mutations abolished this function. Mutations related to amyotrophic lateral sclerosis also negated the inhibition of interferon regulatory factor-3. The missense mutation showed a cyotoplasmic distribution different from that of the wild type. There are no specific clinical symptoms related to optineurin. However, severe brain atrophy was detected in patients with homozygous deletion. Neuropathologically, an E478G patient showed transactive response DNA-binding protein of 43 kDa-positive neuronal intracytoplasmic inclusions in the spinal and medullary motor neurons. Furthermore, Golgi fragmentation was identified in 73% of this patient's anterior horn cells. In addition, optineurin is colocalized with fused in sarcoma in the basophilic inclusions of amyotrophic lateral sclerosis with fused in sarcoma mutations, and in basophilic inclusion body disease. These findings strongly suggest that optineurin is involved in the pathogenesis of amyotrophic lateral sclerosis.

    2006-07-01

    Even if the definition and pathophysiology of fatigue in multiple sclerosis (MS) are still debated, and despite the scarcity of objective markers correlated with the subjective sensation of fatigue, a review of the literature shows the importance of its detection and management, and allows one to propose therapeutic strategies. Fatigue is not only the most frequently reported symptom in MS, but also a frequent source of activity and participation limitations, psychological distress, and impairment of quality of life. Its management, which must be initiated early, is based on a comprehensive evaluation of its characteristics and consequences (sometimes with the use of scales such as the Fatigue Severity Scale and the Modified Fatigue Impact Scale), and on the identification of many potential contributing factors (psychological disorders, sleep disturbances, pain, infections and other comorbidities, medications, and deconditioning). Rehabilitative interventions are essential to the treatment of fatigue. Beyond the traditional energy conservation strategies and cooling techniques, several randomized controlled studies have demonstrated the positive impact of aerobic exercise. Medications are partially beneficial, and with the exception of amantadine, their efficacy has not been confirmed by randomized double-blind trials.

  5. Tuberous sclerosis complex.

    PubMed

    Islam, Monica P; Roach, E Steve

    2015-01-01

    Tuberous sclerosis complex (TSC) is a neurocutaneous syndrome that can affect the brain, skin, eyes, kidneys, heart, and lungs. TSC alters cellular proliferation and differentiation, resulting in hamartomas of various organs, tumor formation, and altered neuronal migration. The phenotype is highly variable. Most individuals have seizures, commonly including infantile spasms, and there is variable intellectual disability and autism. Neonates can present with cardiac failure due to intracardiac rhabdomyomas. The likelihood of renal angiomyolipomas increases with age, and renal disease is the most common cause of death in adults with TSC. Pulmonary involvement occurs predominantly in women and carries a high morbidity and mortality. TSC is inherited as an autosomal dominant trait, but spontaneous mutations are common. A mutation of either TSC1 on chromosome 9 or TSC2 on chromosome 16 leads to dysfunction of hamartin or tuberin, respectively. These two proteins form a functional complex that modulates the mammalian target of rapamycin (mTOR) pathway. Medications that inhibit mTOR are being used to treat TSC-related tumors, and current studies are investigating whether these agents could alleviate other TSC complications. Consensus statements guide identification and optimal management of many of the TSC-related complications at diagnosis and throughout the lifespan. A multidisciplinary approach is necessary for optimal management of individuals with TSC.

  6. Albumin and multiple sclerosis.

    PubMed

    LeVine, Steven M

    2016-04-12

    Leakage of the blood-brain barrier (BBB) is a common pathological feature in multiple sclerosis (MS). Following a breach of the BBB, albumin, the most abundant protein in plasma, gains access to CNS tissue where it is exposed to an inflammatory milieu and tissue damage, e.g., demyelination. Once in the CNS, albumin can participate in protective mechanisms. For example, due to its high concentration and molecular properties, albumin becomes a target for oxidation and nitration reactions. Furthermore, albumin binds metals and heme thereby limiting their ability to produce reactive oxygen and reactive nitrogen species. Albumin also has the potential to worsen disease. Similar to pathogenic processes that occur during epilepsy, extravasated albumin could induce the expression of proinflammatory cytokines and affect the ability of astrocytes to maintain potassium homeostasis thereby possibly making neurons more vulnerable to glutamate exicitotoxicity, which is thought to be a pathogenic mechanism in MS. The albumin quotient, albumin in cerebrospinal fluid (CSF)/albumin in serum, is used as a measure of blood-CSF barrier dysfunction in MS, but it may be inaccurate since albumin levels in the CSF can be influenced by multiple factors including: 1) albumin becomes proteolytically cleaved during disease, 2) extravasated albumin is taken up by macrophages, microglia, and astrocytes, and 3) the location of BBB damage affects the entry of extravasated albumin into ventricular CSF. A discussion of the roles that albumin performs during MS is put forth.

    Purpose to Review To highlight the pathological features and clinical aspects of progressive multiple sclerosis (PMS). To highlight results of clinical trial experience to date and review ongoing clinical trials and perspective new treatment options. Explain the challenges of clinical trial design in PMS. Recent Findings MS has been identified as a chronic immune mediated disease, and the progressive phase of the disease appears to have significant neurodegenerative mechanisms. The classification of the course of PMS has been re-organized into categories of active vs. inactive inflammatory disease and the presence vs. absence of gradual disease progression. This differentiation allows clearer conceptualization of PMS and possibly even more efficient recruitment of PMS subjects into clinical trials. Clinical trial experience to date in PMS has been negative with anti-inflammatory medications used in relapsing MS. Simvastatin was recently tested in a phase II trial and showed a 43% reduction on annualized atrophy progression in secondary progressive MS. Ongoing PMS trials are currently being conducted with the phosphodiesterase inhibitor ibudilast, S1P modulator siponimod, and anti-B-cell therapy ocrelizumab. Several efforts for development of outcome measures in PMS are ongoing. Summary PMS represents a significant challenge, as the pathogenesis of the disease is not well understood, no validated outcome metrics have been established, and clinical trial experience to date has been disappointing. Advances in the understanding of the disease and lessons learned in previous clinical trials are paving the way for successful development of disease modifying agents for this disease. PMID:25887766

    Importance of the field Systemic-sclerosis (SSc) is an uncommon autoimmune disease with variable degrees of fibroproliferation in blood vessels and certain organs of the body. Presently, there is no cure for SSc. The purpose of this article is to review the current literature regarding pathogenesis and treatment of complications of SSc. Areas covered in this review All available articles regarding research related to SSc pathogenesis and treatment listed in the PubMed.gov database were searched, relevant articles were then reviewed and used as sources of information for this review. What the reader will gain This review attempts for the reader to highlight some current thought regarding mechanisms of SSc pathogenesis and how autoimmunity relates to vascular changes and fibrogenesis of the disease plus provide a review of results of completed clinical trials and current on-going clinical trials that address organ specific or global therapies for this disease which can aid physicians who provide medical care for patients with SSc. Take home message SSc is a complex autoimmune disease, the pathogenesis of which although not completely understood is under active study, and new insights into pathogenesis are continuously being discovered. Although there is no effective disease modifying treatment for patients with SSc, quality of life, morbidity and mortality can be improved by using targeted therapy directed at affecting the consequences of damage to lungs, blood vessels, kidneys and the gastrointestinal tract. Innovative approaches to treating SSc are under intense investigation. PMID:20210685

    Multiple sclerosis (MS) is one of the most frequently seen neurological causes of progressive disability in early to middle adulthood. The disease is variable in its presentation and course, affects roughly 100-300 per 100,000 persons within the United States alone, and is slightly more common among females than males. MS places substantial burdens on patients, families, and caregivers. It negatively affects cognitive abilities and psychiatric functioning, and can add a notably deleterious effect on a patient's quality of life. This chapter reviews the recent literature on the behavioral manifestations of MS. Cognitive domains discussed include executive functioning, processing speed, attention, learning and memory, language functioning, and visual spatial processing. Some attention will also be paid to differential diagnosis and the cognitive effects of treatment. Psychiatric manifestations are also discussed, including symptoms of depression, bipolar disorder, euphoria, pathological laughter and crying, and psychosis, as well as maladaptive personality traits. Finally, the chapter concludes with a discussion of the effects of MS on quality of life including such areas as fatigue, sexual dysfunction, pain, employment, and cognitive functioning.

    Tuberous sclerosis complex (TSC) is an autosomal dominant disorder that affects multiple organ systems and is caused by loss-of-function mutations in one of two genes: TSC1 or TSC2. The disorder can affect both adults and children. First described in depth by Bourneville in 1880, it is now estimated that nearly 2 million people are affected by the disease worldwide. The clinical features of TSC are distinctive and can vary widely between individuals, even within one family. Major features of the disease include tumours of the brain, skin, heart, lungs and kidneys, seizures and TSC-associated neuropsychiatric disorders, which can include autism spectrum disorder and cognitive disability. TSC1 (also known as hamartin) and TSC2 (also known as tuberin) form the TSC protein complex that acts as an inhibitor of the mechanistic target of rapamycin (mTOR) signalling pathway, which in turn plays a pivotal part in regulating cell growth, proliferation, autophagy and protein and lipid synthesis. Remarkable progress in basic and translational research, in addition to several randomized controlled trials worldwide, has led to regulatory approval of the use of mTOR inhibitors for the treatment of renal angiomyolipomas, brain subependymal giant cell astrocytomas and pulmonary lymphangioleiomyomatosis, but further research is needed to establish full indications of therapeutic treatment. In this Primer, we review the state-of-the-art knowledge in the TSC field, including the molecular and cellular basis of the disease, medical management, major knowledge gaps and ongoing research towards a cure.

    Patients with multiple sclerosis (MS), a disease of the central nervous system that disrupts signals within the brain and also the signals between the brain and body, will likely experience symptoms that may negatively impact their quality of life (QOL). Due to the complexity of MS and its disease burden, multidisciplinary management that combines pharmacologic and nonpharmacologic strategies with patient education is necessary. Diagnosing relapses of MS in clinical practice can be difficult due to the multiple subtypes of MS, variations of symptomatology, and pseudo-relapses. Managing relapses also presents its own set of challenges, for example, evaluating if treatment is appropriate and determining which agent would be most effective for a patient if treatment is recommended. Patient education is essential for achieving optimal outcomes for patients with MS and improving patient QOL, and should increase awareness of: (1) the disease itself and its progression; (2) the signs and symptoms of MS; (3) current treatment strategies and plan of care; (4) the recognition and management of relapses; (5) the value of treatment adherence and impact of nonadherence; and (6) hope for the future. The management of active MS may be further complicated by the complex variety of pharmacotherapeutic options, and in some instances, by having to switch between agents and drug classes. Newer agents in development (eg, alemtuzumab, ocrelizumab, laquinimod) offer the opportunity to expand the therapeutic armamentarium, although further long-term data are required to evaluate any safety concerns associated with newer agents.

    Pulmonary tuberous sclerosis produced interstitial disease in a woman with normal-sized lungs; numerous hemosiderin-laden macrophages were found in the fluid obtained through bronchoalveolar lavage. The pathological changes seen in the lungs were identical to those of pulmonary lymphangiomyomatosis, in which the constellation of clinical signs usually found in tuberous sclerosis is absent. The two conditions are sufficiently similar in clinical presentation, pathological changes and prognosis to be considered variants of the same disease. The recent findings of progestin receptors in lung tissue from patients with pulmonary lymphangiomyomatosis will likely direct future management towards hormonal manipulation.

    Multiple sclerosis is a multifocal demyelinating disease leading to progressive neurodegeneration caused by an autoimmune response in genetically predisposed individuals. In the last few years, the knowledge and management of this disease has been revolutionized by a series of findings. The present article reviews pathological features of the disease, in which cortical involvement is increasingly implicated, and aspects related to novel pathogenic mechanisms, such as the role of the microbiota in the genesis of multiple sclerosis, as well as recent contributions from the fields of epidemiology and genetics. Also reviewed are the latest diagnostic criteria, which currently allow a much earlier diagnosis, with clear therapeutic implications.

    Multiple sclerosis, the most common disabling disease of the central nervous system affecting young adults, is diagnosed primarily from a history of typical relapsing and remitting white matter symptoms supported by objective signs. Multiple sclerosis may present in more insidious ways or may be mimicked by other diseases, which seemingly satisfy the diagnostic criteria of dissemination in time and space. Patients need psychological support to deal with an uncertain future. A multidisciplinary team approach can best manage both acute temporary disability and, often later, progressive physical and occasionally mental disability. ImagesFigures 1-3 PMID:21221279

    Objective: To investigate the safety and efficacy of rituximab in multiple sclerosis (MS). Methods: In this retrospective uncontrolled observational multicenter study, off-label rituximab-treated patients with MS were identified through the Swedish MS register. Outcome data were collected from the MS register and medical charts. Adverse events (AEs) grades 2–5 according to the Common Terminology Criteria for Adverse Events were recorded. Results: A total of 822 rituximab-treated patients with MS were identified: 557 relapsing-remitting MS (RRMS), 198 secondary progressive MS (SPMS), and 67 primary progressive MS (PPMS). At baseline, 26.2% had contrast-enhancing lesions (CELs). Patients were treated with 500 or 1,000 mg rituximab IV every 6–12 months, during a mean 21.8 (SD 14.3) months. During treatment, the annualized relapse rates were 0.044 (RRMS), 0.038 (SPMS), and 0.015 (PPMS), and 4.6% of patients displayed CELs. Median Expanded Disability Status Scale remained unchanged in RRMS (p = 0.42) and increased by 0.5 and 1.0 in SPMS and PPMS, respectively (p = 0.10 and 0.25). Infusion-related AEs occurred during 7.8% of infusions and most were mild. A total of 89 AEs grades ≥2 (of which 76 infections) were recorded in 72 patients. No case of progressive multifocal leukoencephalopathy was detected. Conclusions: This is the largest cohort of patients with MS treated with rituximab reported so far. The safety, clinical, and MRI findings in this heterogeneous real-world cohort treated with different doses of rituximab were similar to those reported in previous randomized controlled trials on B-cell depletion therapy in MS. Classification of evidence: This study provides Class IV evidence that for patients with MS, rituximab is safe and effective. PMID:27760868

    Multiple sclerosis (MS) is a chronic but incurable disease of the central nervous system (CNS) that is often diagnosed in the second or third decade of life. It is more common among women than men, significantly impairs patient quality of life, and is associated with substantial costs to patients, healthcare systems, and society. Of the approximately 2.3 million individuals worldwide that have MS, more than 400,000 reside in the United States. Although the etiology of MS is not completely understood, a great deal of evidence suggests a complex relationship between environmental and genetic factors. The pathophysiology of MS involves an aberrant attack by the host immune system on oligodendrocytes, which synthesize and maintain myelin sheaths in the CNS. There are 4 identified disease courses in MS, and approximately 85% of people with MS present with relapsing-remitting MS, which is characterized by discrete acute attacks followed by periods of remission. Signs and symptoms of MS are dependent on the demyelinated area(s) of the CNS and often involve sensory disturbances, limb weakness, fatigue, and increased body temperature. The criteria for a diagnosis of MS include evidence of damage in at least 2 separate areas of the CNS, evidence that the damage occurred at different time points, and the ruling out of other possible diagnoses. Diseasemodifying drugs (DMDs) that reduce the frequency of relapses, development of brain lesions, and progression of disability are the standard of care for relapsing forms of MS, and the use of DMDs should be initiated as early as possible.

    A number of studies have been conducted with the onset of secondary progressive multiple sclerosis as an inclusion criterion or an outcome of interest. However, a standardized objective definition of secondary progressive multiple sclerosis has been lacking. The aim of this work was to evaluate the accuracy and feasibility of an objective definition for secondary progressive multiple sclerosis, to enable comparability of future research studies. Using MSBase, a large, prospectively acquired, global cohort study, we analysed the accuracy of 576 data-derived onset definitions for secondary progressive multiple sclerosis and first compared these to a consensus opinion of three neurologists. All definitions were then evaluated against 5-year disease outcomes post-assignment of secondary progressive multiple sclerosis: sustained disability, subsequent sustained progression, positive disability trajectory, and accumulation of severe disability. The five best performing definitions were further investigated for their timeliness and overall disability burden. A total of 17 356 patients were analysed. The best definition included a 3-strata progression magnitude in the absence of a relapse, confirmed after 3 months within the leading Functional System and required an Expanded Disability Status Scale step ≥4 and pyramidal score ≥2. It reached an accuracy of 87% compared to the consensus diagnosis. Seventy-eight per cent of the identified patients showed a positive disability trajectory and 70% reached significant disability after 5 years. The time until half of all patients were diagnosed was 32.6 years (95% confidence interval 32-33.6) after disease onset compared with the physicians' diagnosis at 36 (35-39) years. The identified patients experienced a greater disease burden [median annualized area under the disability-time curve 4.7 (quartiles 3.6, 6.0)] versus non-progressive patients [1.8 (1.2, 1.9)].

    Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterised by progressive muscular paralysis reflecting degeneration of motor neurones in the primary motor cortex, corticospinal tracts, brainstem and spinal cord. Incidence (average 1.89 per 100,000/year) and prevalence (average 5.2 per100,000) are relatively uniform in Western countries, although foci of higher frequency occur in the Western Pacific. The mean age of onset for sporadic ALS is about 60 years. Overall, there is a slight male prevalence (M:F ratio~1.5:1). Approximately two thirds of patients with typical ALS have a spinal form of the disease (limb onset) and present with symptoms related to focal muscle weakness and wasting, where the symptoms may start either distally or proximally in the upper and lower limbs. Gradually, spasticity may develop in the weakened atrophic limbs, affecting manual dexterity and gait. Patients with bulbar onset ALS usually present with dysarthria and dysphagia for solid or liquids, and limbs symptoms can develop almost simultaneously with bulbar symptoms, and in the vast majority of cases will occur within 1–2 years. Paralysis is progressive and leads to death due to respiratory failure within 2–3 years for bulbar onset cases and 3–5 years for limb onset ALS cases. Most ALS cases are sporadic but 5–10% of cases are familial, and of these 20% have a mutation of the SOD1 gene and about 2–5% have mutations of the TARDBP (TDP-43) gene. Two percent of apparently sporadic patients have SOD1 mutations, and TARDBP mutations also occur in sporadic cases. The diagnosis is based on clinical history, examination, electromyography, and exclusion of 'ALS-mimics' (e.g. cervical spondylotic myelopathies, multifocal motor neuropathy, Kennedy's disease) by appropriate investigations. The pathological hallmarks comprise loss of motor neurones with intraneuronal ubiquitin-immunoreactive inclusions in upper motor neurones and TDP-43 immunoreactive inclusions in

    Multiple sclerosis (MS) is the most frequently seen demyelinating disease, with a prevalence that varies considerably, from high levels in North America and Europe (>100/100,000 inhabitants) to low rates in Eastern Asia and sub-Saharan Africa (2/100,000 population). Knowledge of the geographical distribution of the disease and its survival data, and a better understanding of the natural history of the disease, have improved our understanding of the respective roles of endogenous and exogenous causes of MS. Concerning mortality, in a large French cohort of 27,603 patients, there was no difference between MS patients and controls in the first 20 years of the disease, although life expectancy was reduced by 6-7 years in MS patients. In 2004, the prevalence of MS in France was 94.7/100,000 population, according to data from the French National Health Insurance Agency for Salaried Workers (Caisse nationale d'assurance maladie des travailleurs Salariés [CNAM-TS]), which insures 87% of the French population. This prevalence was higher in the North and East of France. In several countries, including France, the gender ratio for MS incidence (women/men) went from 2/1 to 3/1 from the 1950s to the 2000s, but only for the relapsing-remitting form. As for risk factors of MS, the most pertinent environmental factors are infection with Epstein-Barr virus (EBV), especially if it arises after childhood and is symptomatic. The role of smoking in MS risk has been confirmed, but is modest. In contrast, vaccines, stress, traumatic events and allergies have not been identified as risk factors, while the involvement of vitamin D has yet to be confirmed. From a genetic point of view, the association between HLA-DRB1*15:01 and a high risk of MS has been known for decades. More recently, immunogenetic markers have been identified (IL2RA, IL7RA) and, in particular thanks to studies of genome-wide associations, more than 100 genetic variants have been reported. Most of these are involved in

    The aim of the study is to investigate acoustic reflex testing in amyotrophic lateral sclerosis patients. Amplitude, latency, and rise time of stapedial reflex were recorded for 500 and 1000 Hz contralateral stimulus. Statistical analysis was performed by the Wilcoxon test and the level of significance was set at 5 %. Fifty-one amyotrophic lateral sclerosis patients and ten sex- and age-matched control subjects were studied. Patients were further divided in two groups: amyotrophic lateral sclerosis-bulbar (38 cases, with bulbar signs at evaluation) and amyotrophic lateral sclerosis-spinal (13 cases, without bulbar signs at evaluation). Stapedial reflex was present in all patients. There was a statistically significant difference in the mean amplitude, latency, and rise time between the amyotrophic lateral sclerosis patients as compared with the controls. Amplitude was lower in both the amyotrophic lateral sclerosis-bulbar and the amyotrophic lateral sclerosis-spinal patients than in the controls (p < 0.05) and rise time was longer in both patient groups compared with the controls (p < 0.05). These results confirm the presence of abnormal acoustic reflex patterns in amyotrophic lateral sclerosis cases with bulbar signs and, moreover, suggesting a possible subclinical involvement of the stapedial motor neuron even in amyotrophic lateral sclerosis-spinal patients. Amplitude and rise time seem to be good sensitive parameters for investigating subclinical bulbar involvement.

    Natalizumab is the first monoclonal antibody approved for the treatment of relapsing multiple sclerosis. Pivotal trials demonstrated the efficacy of natalizumab on clinical and paraclinical measures of disease activity and disability progression. Although a direct comparison has not been performed yet, natalizumab seems to be more efficacious than the currently available immunomodulant drugs, such as IFN-β and glatiramer acetate. Despite its efficacy, the occurrence of an increased risk of progressive multifocal leukoencephalopathy with the treatment, raises concerns about its widespread use in multiple sclerosis patients. This paper provides an overview of the most relevant results from the Phase I-IV studies on natalizumab and highlights the challenges addressed to minimize and manage its adverse events in clinical practice.

    Tolerogenic vaccines represent a new class of vaccine designed to re-establish immunological tolerance, restore immune homeostasis, and thereby reverse autoimmune disease. Tolerogenic vaccines induce long-term, antigen-specific, inhibitory memory that blocks pathogenic T cell responses via loss of effector T cells and gain of regulatory T cell function. Substantial advances have been realized in the generation of tolerogenic vaccines that inhibit experimental autoimmune encephalomyelitis in a preclinical setting, and these vaccines may be a prequel of the tolerogenic vaccines that may have therapeutic benefit in Multiple Sclerosis. The purpose here is to provide a snapshot of the current concepts and future prospects of tolerogenic vaccination for Multiple Sclerosis, along with the central challenges to clinical application.

The increasing number of available drugs is paralleled by impelling issue of ensuring the most appropriate treatment to the right patient at the right time. The purpose of this review is to describe novel agents recently approved for multiple sclerosis treatment, namely teriflunomide, alemtuzumab and dimethylfumarate, focusing on mechanism of action, efficacy data in experimental setting, safety and tolerability. The place in therapy of newer treatment implies careful balancing of risk-benefit profile as well as accurate patient selection. Hence the widening of therapeutic arsenal provides greater opportunity for personalized therapy but also entails a complex trade-off between efficacy, tolerability, safety and eventually patient preference.

    Multiple sclerosis is characterized by a non-homogeneous distribution around the world. Some authors in past described a latitude gradient, with increasing risk from the equator to North and South Poles, but this theory is still controversial. Regarding Europe, there are many articles in the literature concerning the epidemiology of this disease but, unfortunately, they are not always comparable due to different methodologies, they do not cover all countries in the continent, and most of them reported data of small areas and rarely at a national level. In 2012 there were 20 national registries that could help to describe the epidemiology of the disease and, in addition, there is an European Register for Multiple Sclerosis that collect data from already existing national or regional MS registries and databases. Another valid alternative to obtain epidemiological data, also at national level, in a routinely and cost-saving way is through administrative data that are of increasing interest in the last years.

    Multiple sclerosis is the most common inflammatory, chronic and degenerative condition of the central nervous system, and represents the first cause of disability in young adults. In Mexico, 11 to 20 out of every 100 000 people suffer from this disease. The causes of multiple sclerosis remain unknown, but several theories have been proposed: the interaction of environmental factors, viral infectious factors and genetic and immune susceptibility of each individual patient, which induce an autoimmune response and promote neuronal/axonal degeneration. In this review, the immune reaction main components and neurodegeneration present in multiple sclerosis are analyzed, as well as the inflammatory cascade associated with demyelination. Available treatments' main purpose is to modulate aspects related to the adaptive immune response (B and T cells). The therapeutic challenge will be antigen-specific immune-tolerance induction, for example, with the use of tolerance protocols with peptides or DNA or nanoparticles vaccines. Future therapies should aim to control innate components (microglia, macrophages, astrocytes) and to promote remyelination. To optimize the treatment, a combined therapeutic approach targeting the control of inflammatory and neurodegenerative components of the disease and monitoring of biomarkers will be necessary.

    Ziemssen, Tjalf

    2009-02-01

    Depression and fatigue are common symptoms of multiple sclerosis and are the primary determinants of impaired quality of life in this demyelinating neurological disease. The twelve-month prevalence of major depression in patients with multiple sclerosis is around 15%. Untreated depression is associated with suicidal ideation, impaired cognitive function and poor adherence to immunomodulatory treatment. For these reasons, systematic screening and management of depressive symptoms is recommended for all patients with multiple sclerosis. There is some evidence that interferon-beta treatment may exacerbate depressive symptoms and a switch to glatiramer acetate can be envisaged in patients treated with an interferon-beta in whom depressive symptoms become an issue. Fatigue is present in over three-quarters of patients with multiple sclerosis. It is considered the most debilitating symptom of the disease and is a major reason for work absenteeism. There is growing evidence that immunomodulatory treatments, in particular glatiramer acetate, improve fatigue symptoms in patients with multiple sclerosis.

  16. Endocannabinoids in Multiple Sclerosis and Amyotrophic Lateral Sclerosis.

    2015-01-01

    There are numerous reports that people with multiple sclerosis (MS) have for many years been self-medicating with illegal street cannabis or more recently medicinal cannabis to alleviate the symptoms associated with MS and also amyotrophic lateral sclerosis (ALS). These anecdotal reports have been confirmed by data from animal models and more recently clinical trials on the ability of cannabinoids to alleviate limb spasticity, a common feature of progressive MS (and also ALS) and neurodegeneration. Experimental studies into the biology of the endocannabinoid system have revealed that cannabinoids have efficacy, not only in symptom relief but also as neuroprotective agents which may slow disease progression and thus delay the onset of symptoms. This review discusses what we now know about the endocannabinoid system as it relates to MS and ALS and also the therapeutic potential of cannabinoid therapeutics as disease-modifying or symptom control agents, as well as future therapeutic strategies including the potential for slowing disease progression in MS and ALS.

    Multiple sclerosis (MS) is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS) and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment. PMID:26538847

    Driving is an important issue for young patients, especially for those whose walking capacity is impaired. Driving might support the patient's social and vocational participation. The question as to whether a patient with multiple sclerosis (MS) is restricted in the ability to drive a car depends on neurological and neuropsychological deficits, self-awareness, insight into deficits and ability to compensate for loss of function. Because of the enormous variability of symptoms in MS the question is highly individualized. A practical driving test under supervision of a driving instructor (possibly accompanied by a neuropsychologist) might be helpful in providing both patient and relatives adequate feedback on driving abilities.

  19. Spasticity management in multiple sclerosis.

    PubMed

    Hughes, Christina; Howard, Ileana M

    2013-11-01

    Spasticity is a prevalent and potentially disabling symptom common in individuals with multiple sclerosis. Adequate evaluation and management of spasticity requires a careful assessment of the patient's history to determine functional impact of spasticity and potential exacerbating factors, and physical examination to determine the extent of the condition and culpable muscles. A host of options for spasticity management are available: therapeutic exercise, physical modalities, complementary/alternative medicine interventions, oral medications, chemodenervation, and implantation of an intrathecal baclofen pump. Choice of treatment hinges on a combination of the extent of symptoms, patient preference, and availability of services.

    2013-11-01

    Before the development of magnetic resonance imaging (MRI), evoked potentials (EPs)-visual evoked potentials, somatosensory evoked potentials, and brain stem auditory evoked responses-were commonly used to determine a second site of disease in patients being evaluated for possible multiple sclerosis (MS). The identification of an area of the central nervous system showing abnormal conduction was used to supplement the abnormal signs identified on the physical examination-thus identifying the "multiple" in MS. This article is a brief overview of additional ways in which central nervous system (CNS) physiology-as measured by EPs-can still contribute value in the management of MS in the era of MRIs.

    This review of the differential diagnosis of amyotrophic lateral sclerosis focuses on two themes. The first is practical, how to establish the diagnosis based primarily on clinical findings buttressed by electrodiagnosis. The main considerations are multifocal motor neuropathy and cervical spondylotic myelopathy. The second theme is the relationship of motor neuron disease to other conditions, including benign fasciculation (Denny-Brown, Foley syndrome), paraneoplastic syndromes, lymphoproliferative disease, radiation damage, monomelic amyotrophy (Hirayama syndrome), as well as an association with parkinsonism, dementia and multisystem disorders of the central nervous system.

    The use of magnetic resonance imaging (MRI) in patients with multiple sclerosis has markedly increased in recent years. The main task of the MRI studies after the diagnosis of multiple sclerosis is to assess the dynamics of MRI for determining disease progression and monitoring the efficacy of therapy. In this regard, it is very important to obtain the most identical baseline and follow-up MRI that is possible when a single standard protocol is used. This article presents the protocol of brain MRI and spinal cord MRI and interpretation of MRI studies in patients with multiple sclerosis.

    There was more neurology taught under Harold G. Wolff at Cornell University Medical College in New York than perhaps anywhere else in the country when I attended from 1948 to 1952. I took my residency at the Veterans Administration Hospital in the Bronx, New York, a teaching hospital of Cornell, with Wolff as my Director of Training. While a resident, we thought we had found a treatment for multiple sclerosis. To test our conclusion, the first Class 1 treatment trial ever conducted for multiple sclerosis was performed. This showed no effect, but the participants began investigating multiple sclerosis among the 16 million persons at prime age for symptom onset who had served in the military in World War II. This led me to study its epidemiology worldwide, beginning with a detailed review of all published population-based estimates of frequency. Among these were nationwide surveys from Sweden, Denmark, Switzerland and later Norway and Finland, which showed in each country a concentration of the significantly high regions into contiguous areas forming a single 'focus' in each land, maximal in Denmark under the age of 15 years. The primary locus of high frequency multiple sclerosis seemed to be in the south-central inland lake region of Sweden, with spread to its contiguous neighbours. These concentrations in time and space indicated that multiple sclerosis was a disease probably acquired in early adolescence. Migration studies supported this: moves from high to low showed retention of birthplace risk only for those aged >15 years, whereas opposite moves indicated susceptibility limited to some 11-45 year olds. Epidemics of multiple sclerosis would suggest the disease is not only acquired but also infectious. If an infectious origin were true, transmission would have to occur before clinical onset, and would have to involve a much greater number of subjects than clinically involved. I believe there have been epidemics in Iceland, Shetland-Orkney and the Faroe Islands

    HLA typing in Wellington revealed a stronger association of multiple sclerosis with DR2 than with DQw1. The association with DQw1 appeared to be due to linkage disequilibrium of this antigen with DR2. These results, when considered in conjunction with other studies, are most easily explained by the hypothesis that susceptibility to multiple sclerosis is influenced by multiple risk factors, with DR2 being an important risk factor in Caucasoid populations.

    Multiple sclerosis is an autoimmune disease of the central nervous system characterized by inflammatory demyelination and axonal degeneration. It is the commonest cause of permanent disability in young adults. Environmental and genetic factors have been suggested in its etiology.

    Multiple sclerosis associated with neurofibromatosis type 1 (NF1) is a very rare event. Seven patients with multiple sclerosis and NF1 are described in the literature, and all were reported to have the primary progressive form of multiple sclerosis. Three new patients with NF1 that developed multiple sclerosis are described and it is shown that the range of multiple sclerosis associated with NF1 includes the relapsing forms of the disease. The risk of having both NF1 and multiple sclerosis in north east Italy is higher than would be expected based on the prevalence rates of the two diseases.

    Multiple sclerosis (MS) and antiphospholipid syndrome (APS) share common clinical, laboratory and radiological features. We reviewed all the English papers on MS and APS published in the literature from 1965 to 2014 using PubMed and Google Scholar. We found that APS can mimic antiphospholipid antibodies (aPL)-positive MS in many ways in its clinical presentation. Nevertheless, APS diagnosis, clinical manifestations and management differ from those of MS. aPL were found in MS patients with titers ranging from 2% to 88%. The distribution and volume of lesions on magnetic resonance imaging (MRI) may help to differentiate MS from primary APS. In addition, atypical MS presentation can guide physicians toward an alternative diagnosis, especially when features of thrombosis and/or history of connective tissue disease are present. In that case, an anticoagulation trial could be worthwhile.

    Systemic sclerosis (SSc) is a multisystem disease of unknown aetiology characterised by microangiopathy, dysregulated immune function and tissue remodelling, which commonly involves the oral cavity. Orofacial manifestations of SSc contribute greatly to overall disease burden and yet are regularly overlooked and under-treated. This may reflect a pre-occupation amongst rheumatology clinicians on potentially life-threatening internal organ involvement, but is also a consequence of insufficient engagement between rheumatologists and dental professionals. A high proportion of SSc patients report difficulty accessing a dentist with knowledge of the disease and there is recognition amongst dentists that this could impact negatively on patient care. This review shall describe the clinical features and burden of orofacial manifestations of SSc and the management of such problems. The case is made for greater collaborative working between rheumatologists and dental professionals with an interest in SSc in both the research and clinical setting.

    2015-01-01

    Multiple sclerosis (MS) is a chronic, progressive central neurological disease characterized by inflammation and demyelination. In patients with MS, dysregulation of the autonomic nervous system may present with various clinical symptoms including sweating abnormalities, urinary dysfunction, orthostatic dysregulation, gastrointestinal symptoms, and sexual dysfunction. These autonomic disturbances reduce the quality of life of affected patients and constitute a clinical challenge to the physician due to variability of clinical presentation and inconsistent data on diagnosis and treatment. Early diagnosis and initiation of individualized interdisciplinary and multimodal strategies is beneficial in the management of autonomic dysfunction in MS. This review summarizes the current literature on the most prevalent aspects of autonomic dysfunction in MS and provides reference to underlying pathophysiological mechanisms as well as means of diagnosis and treatment.

    This article reviews our current understanding and modern treatment of multiple sclerosis (MS). MS is a disabling condition resulting in devastating social and economic impacts. As MS can affect any part of the central nervous system, the presentation is often diverse; however, there are key features that can be useful in the clinic. We comment on the diagnostic criteria and review the main subtypes of MS, including clinically isolated syndrome, relapsing remitting MS, secondary progressive MS and primary progressive MS. Although the underlying aetiology of MS is still not known, we summarise those with most evidence of association. Finally, we aim to present treatment strategies for managing the acute relapse, disease-modifying therapies and MS symptoms. This review highlights that progressive MS is an area where there is currently a paucity of available disease-modifying treatments and this will be a major focus for future development.

  17. Intensive immunosuppression in multiple sclerosis.

    2006-03-01

    Immunosuppressive drugs have been used out of label in multiple sclerosis (MS) for over 30 years and around 10% of patients are actually under immunosuppressive treatment. The rationale for immunosuppression in MS lies in the hypothesis that MS is an inflammatory immune-mediated disease that can take advantage of strong anti-inflammatory activity. Azathioprine, methotrexate, cyclophosphamide and mitoxantrone are the most utilised agents, but only the latter has been approved for clinically active MS. Many of them are safe in combination with interferon-beta and are under investigation in controlled trials. Plasma exchange is limited to catastrophic attacks in refractory MS whilst bone marrow transplantation is considered in patients with an extremely severe, active disease as the final option in escalation therapy. Although immunosuppressants are best effective in induction therapy, their use is limited by toxicity and potential long-term risk.

    There is increasing evidence that abnormalities in epigenetic mechanisms of gene expression contribute to the development of multiple sclerosis (MS). Advances in epigenetics have given rise to a new class of drugs, epigenetic drugs. Although many classes of epigenetic drugs are being investigated, at present most attention is being paid to two classes of epigenetic drugs: drugs that inhibit DNA methyltransferase (DNMTi) and drugs that inhibit histone deacetylase (HDACi). This paper discusses the potential use of epigenetic drugs in the treatment of MS, focusing on DNMTi and HDACi. Preclinical drug trials of DNMTi and HDACi for the treatment of MS are showing promising results. Epigenetic drugs could improve the clinical management of patients with MS.

Comprehensive metabolomics profiling of plants under JA treatment provides insights into the interaction and regulation network of plant hormones. Here we applied high resolution mass spectrometry based metabolomics approach on Arabidopsis wild type and JA synthesis deficiency mutant opr3. The effects of exogenous MeJA treatment on the metabolites of opr3 were investigated. More than 10000 ion signals were detected and more than 2000 signals showed significant variation in different genotypes and treatment groups. Multivariate statistic analyses (PCA and PLS-DA) were performed and a differential compound library containing 174 metabolites with high resolution precursor ion-product ions pairs was obtained. Classification and pathway analysis of 109 identified compounds in this library showed that glucosinolates and tryptophan metabolism, amino acids and small peptides metabolism, lipid metabolism, especially fatty acyls metabolism, were impacted by endogenous JA deficiency and exogenous MeJA treatment. These results were further verified by quantitative reverse transcription PCR (RT-qPCR) analysis of 21 related genes involved in the metabolism of glucosinolates, tryptophan and α-linolenic acid pathways. The results would greatly enhance our understanding of the biological functions of JA. PMID:27883040

    High-throughput technologies have led to advances in the recognition of disease pathways and their underlying mechanisms. To investigate the impact of micro-RNAs on the disease process in multiple sclerosis, a prototypic inflammatory neurological disorder, we examined cerebral white matter from patients with or without the disease by micro-RNA profiling, together with confirmatory reverse transcription-polymerase chain reaction analysis, immunoblotting and gas chromatography-mass spectrometry. These observations were verified using the in vivo multiple sclerosis model, experimental autoimmune encephalomyelitis. Brains of patients with or without multiple sclerosis demonstrated differential expression of multiple micro-RNAs, but expression of three neurosteroid synthesis enzyme-specific micro-RNAs (miR-338, miR-155 and miR-491) showed a bias towards induction in patients with multiple sclerosis (P < 0.05). Analysis of the neurosteroidogenic pathways targeted by micro-RNAs revealed suppression of enzyme transcript and protein levels in the white matter of patients with multiple sclerosis (P < 0.05). This was confirmed by firefly/Renilla luciferase micro-RNA target knockdown experiments (P < 0.05) and detection of specific micro-RNAs by in situ hybridization in the brains of patients with or without multiple sclerosis. Levels of important neurosteroids, including allopregnanolone, were suppressed in the white matter of patients with multiple sclerosis (P < 0.05). Induction of the murine micro-RNAs, miR-338 and miR-155, accompanied by diminished expression of neurosteroidogenic enzymes and allopregnanolone, was also observed in the brains of mice with experimental autoimmune encephalomyelitis (P < 0.05). Allopregnanolone treatment of the experimental autoimmune encephalomyelitis mouse model limited the associated neuropathology, including neuroinflammation, myelin and axonal injury and reduced neurobehavioral deficits (P < 0.05).

    Amyotrophic Lateral Sclerosis (ALS) is a progressive and fatal neurodegenerative disease in which much burden is geared towards end-of-life care. Particularly in the earlier stages of ALS, many people have found both physiological and psychological boosts from various types of physical exercise for disused muscles. Proper exercise is important for preventing atrophy of muscles from disuse-a key for remaining mobile for as long as possible-and as long as it is possible to exercise comfortably and safely, for preserving cardiovascular fitness. However, the typical neuromuscular patient features a great physical inactivity and disuse weakness, and for that reason many controversial authors have contested exercise in these patients during years, especially in ALS which is rapidly progressive. There is an urgent need for dissecting in detail the real risks or benefits of exercise in controlled clinical trials to demystify this ancient paradigm. Yet, recent research studies document significant benefits in terms of survival and quality of life in ALS, poor cooperation, small sample size, uncontrolled and short-duration trials, remain the main handicaps. Sedentary barriers such as early fatigue and inherent muscle misuse should be overcome, for instance with body-weight supporting systems or non-invasive ventilation, and exercise should be faced as a potential non-monotonous way for contributing to better health-related quality of life.

  8. Clinical neurophysiology of multiple sclerosis.

    PubMed

    Leocani, Letizia; Comi, Giancarlo

    2014-01-01

    The availability of new treatments able to modify the natural course of multiple sclerosis (MS) has generated interest in paraclinical measures to monitor disease evolution. Among these, neurophysiologic measures, mainly evoked potentials (EPs), are used in the functional assessment of central sensorimotor and cognitive networks affected by MS. EP abnormalities may reveal subclinical lesions, objectivate the involvement of sensory and motor pathways in the presence of vague disturbances, and provide indications of the demyelinating nature of the disease process. However, their diagnostic value is much lower than that of magnetic resonance imaging, and is more sensitive to brain and cervical spinal cord lesions. The application of EPs in assessing disease severity and monitoring the evolution of nervous damage is more promising, thanks to their good correlation with disability in cross-sectional and longitudinal studies, and potential use as paraclinical endpoints in clinical trials. Recent evidence indicates that EPs performed early in the disease may help to predict a worse future progression in the long term. If confirmed, these data suggest the possible usefulness of EPs in the early identification of patients who are more likely to develop future disability, thus requiring more frequent monitoring or being potential candidates for more aggressive disease-modifying treatments.

  9. Neuroendocrine Immunoregulation in Multiple Sclerosis

    PubMed Central

    Lee, Wai-Ping; Berneman, Zwi N.

    2013-01-01

    Currently, it is generally accepted that multiple sclerosis (MS) is a complex multifactorial disease involving genetic and environmental factors affecting the autoreactive immune responses that lead to damage of myelin. In this respect, intrinsic or extrinsic factors such as emotional, psychological, traumatic, or inflammatory stress as well as a variety of other lifestyle interventions can influence the neuroendocrine system. On its turn, it has been demonstrated that the neuroendocrine system has immunomodulatory potential. Moreover, the neuroendocrine and immune systems communicate bidirectionally via shared receptors and shared messenger molecules, variously called hormones, neurotransmitters, or cytokines. Discrepancies at any level can therefore lead to changes in susceptibility and to severity of several autoimmune and inflammatory diseases. Here we provide an overview of the complex system of crosstalk between the neuroendocrine and immune system as well as reported dysfunctions involved in the pathogenesis of autoimmunity, including MS. Finally, possible strategies to intervene with the neuroendocrine-immune system for MS patient management will be discussed. Ultimately, a better understanding of the interactions between the neuroendocrine system and the immune system can open up new therapeutic approaches for the treatment of MS as well as other autoimmune diseases.

  10. Therapeutic targets in systemic sclerosis

    2007-01-01

    The precise aetiology of systemic sclerosis (SSc) remains elusive, but significant advances over the past few years have improved our understanding of the underlying pathogenic processes and identified key pathways and mediators that are potential therapeutic targets. The situation is complicated by the clinical heterogeneity of SSc and the differential pathogenesis that underlies the two commonest subsets, namely diffuse and limited cutaneous disease. However, there are common mediators that could be targeted to provide clinical benefit in both types of disease. To date, clinical success with therapies directed against logical profibrotic mediators, such as connective tissue growth factor and transforming growth factor-β, is yet to be reported, although studies are ongoing. More promising clinical results have been obtained with the dual endothelin receptor antagonist bosentan, which has been shown to manage two vascular complications of SSc effectively: pulmonary arterial hypertension and digital ulceration. It remains to be determined whether the identification of additional mediators merely furthers our knowledge of the natural history of SSc or presents targets that can be manipulated to manage SSc patients effectively.

    Cryostat sections of central nervous system (CNS) tissues of patients with multiple sclerosis (MS) and other CNS diseases were stained with antibodies to fibronectin, a macrophage fibronectin receptor component, fibrin/fibrinogen, and albumin using immunoperoxidase. In active, but not inactive, MS plaques vessel fibronectin was increased (to approximately 57% of Factor VIII+ vessels) over uninvolved MS and normal control white matter (P less than 0.001 for both). Fibronectin was primarily localized to vessel walls and amount of staining correlated with degree of inflammation. Active plaques and necrotic lesions also had extracellular fibronectin and fibrin/ogen. These molecules and the fibronectin receptor were found on macrophages. Albumin was more widely and diffusely distributed in lesions than fibronectin. Thus, in addition to extravasation from damaged vessels, fibronectin may be deposited on or synthesized by endothelial cells and macrophages in the CNS. Fibronectin could facilitate monocyte adhesion to endothelial cell luminal surfaces, promote migration of mononuclear cells, and enhance myelin phagocytosis in MS lesions.

    Background Tuberous sclerosis complex (TSC), also known as Bourneville disease, is an inherited, progressive neurocutaneous disorder characterized by the potential for hamartoma formation throughout the body. TSC is an autosomal dominant genetic disorder, but more than two-thirds of cases are sporadic. Methods Clinical manifestations and treatment options are discussed. Both surgical and anesthetic perioperative considerations are described in this review. Results Routine monitoring is appropriate for minor surgical procedures for patients with TSC who have mild disease manifestations. More extensive monitoring is indicated for major procedures that have the potential for significant blood loss and for patients with more severe pathology. Postoperatively, TSC patients should be admitted for monitoring and treatment after more extensive procedures or if significant organ dysfunction occurs. Postoperative complications, which may be related to either the surgery or the TSC pathology itself, may have origins in many different organs and may include seizures, severe hypertension, and bradyarrhythmias. Conclusion TSC is a rare disease with a highly variable clinical presentation and provides a multitude of challenges for the patient, the family, and the healthcare team. PMID:24940133

  13. Islamic fasting and multiple sclerosis

    PubMed Central

    2014-01-01

    Background Month-long daytime Ramadan fasting pose s major challenges to multiple sclerosis (MS) patients in Muslim countries. Physicians should have practical knowledge on the implications of fasting on MS. We present a summary of database searches (Cochrane Database of Systematic Reviews, PubMed) and a mini-symposium on Ramadan fasting and MS. In this symposium, we aimed to review the effect of fasting on MS and suggest practical guidelines on management. Discussion In general, fasting is possible for most stable patients. Appropriate amendment of drug regimens, careful monitoring of symptoms, as well as providing patients with available evidence on fasting and MS are important parts of management. Evidence from experimental studies suggests that calorie restriction before disease induction reduces inflammation and subsequent demyelination and attenuates disease severity. Fasting does not appear to have unfavorable effects on disease course in patients with mild disability (Expanded Disability Status Scale (EDSS) score ≤3). Most experts believed that during fasting (especially in summer), some MS symptoms (fatigue, fatigue perception, dizziness, spasticity, cognitive problems, weakness, vision, balance, gait) might worsen but return to normal levels during feasting. There was a general consensus that fasting is not safe for patients: on high doses of anti-convulsants, anti-spastics, and corticosteroids; with coagulopathy or active disease; during attacks; with EDSS score ≥7. Summary These data suggest that MS patients should have tailored care. Fasting in MS patients is a challenge that is directly associated with the spiritual belief of the patient. PMID:24655543

    Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system characterized by episodic and progressive neurologic dysfunction resulting from inflammatory and autoimmune reactions. The underlying pathogenesis of MS remains largely unclear. However, it is currently accepted as a T cell-mediated autoimmune disease. Among other clinical manifestations, sexual dysfunction (SD) is a painful but still underreported and underdiagnosed symptom of the disorder. SD in MS patients may result from a complex set of conditions and may be associated with multiple anatomic, physiologic, biologic, medical and psychological factors. SD arises primarily from lesions affecting the neural pathways involved in physiologic function. In addition, psychological factors, the side effects of medications and physical symptoms such as fatigue, muscular weakness, menstrual changes, pain and concerns about bladder and bowel incontinence may also be involved. Since MS primarily affects young people, SD secondary to MS may have a great impact on quality of life. Thus, maintaining a healthy sexual life with MS is an important priority. The treatment of SD requires multidisciplinary teamwork and cooperation among specialists, individual patients, partners and the society. PMID:22447199

    The development of new disease-modifying drugs (DMD) in relapsing-remitting multiple sclerosis (RRMS), which share the common denominator of oral administration, considerably improves patient expectations in terms of effectiveness, tolerability and treatment adherence compared with currently available drugs. However, the common route of administration of these drugs does not mean that they are equivalent, since the heading of "oral route" encompasses drugs with distinct indications and mechanisms of action, as well as heterogeneous results in terms of efficacy and safety, allowing treatment to be personalized according to the each patient' s characteristics. Currently, four oral DMD are available or in an advanced stage of clinical development: fingolimod, teriflunomide, dimethyl fumarate and laquinimod. In pivotal trials versus placebo, these molecules reduced the annualized rate of exacerbations versus placebo by 54%, 31%, 53% and 23%, respectively, the risk of progression of disability by 31%, 30%, 38% and 36%, and the number of active lesions showing contrast uptake on magnetic resonance imaging by 82%, 80%, 90% and 37%, respectively. Based on the risk/benefit ratio, fingolimod is indicated in patients with suboptimal response to initial DMD or in severe rapidly progressing RRMS, while the remaining drugs can be used as first-line options. Clinical experience with these treatments will provide new data on safety and effectiveness, which will be determinant when establishing therapeutic algorithms.

    Integrins are the foremost family of cell adhesion molecules that regulate immune cell trafficking in health and diseases. Integrin alpha4 mediates organ-specific migration of immune cells to the inflamed brain, thereby playing the critical role in the pathogenesis of multiple sclerosis. Anti-alpha4 integrin therapy aiming to block infiltration of autoreactive lymphocytes to the inflamed brain has been validated in several clinical trials for the treatment of multiple sclerosis. This paper provides readers with an overview of the molecular and structural bases of integrin activation as well as rationale for using anti-alpha4 integrin therapy for multiple sclerosis and then chronicles the rise and fall of this treatment strategy using natalizumab, a humanized anti-alpha4 integrin.

    Chlamydia and antibodies to them were detected by serological, molecular biological, and culture methods in the sera and cerebrospinal fluid of patients with multiple sclerosis and in the reference groups of subjects without neurological diseases. Correlations between the agent presence in the biological fluids of patients and clinical characteristics of the disease were analyzed. C. pneumoniae were more incident in the biological liquids of patients with multiple sclerosis than in healthy volunteers. On the other hand, the incidence of the agent in the patients was not high and its presence did not correlate with the clinical manifestations. C. trachomatis was equally rare in the patients and volunteers. The studies indicated the existence of a group of patients infected by C. pneumoniae in the cohort of patients with multiple sclerosis, but the impact of this agent for the disease course remains unclear.

    The prominent or isolated weakness of cervical extensor muscles is a relatively rare clinical sign. Commonly, this is known as "dropped-head syndrome". This abnormal flexion of the head may occur in a variety of neuromuscular diseases and in a few non-neurological disorders as well. Systemic sclerosis is a clinically heterogeneous disorder which affects small arteries, microvessels and connective tissue with the involvement of multiple organs such as lung, heart, kidney and gastrointestinal tract. There is no evidence in literature of association between dropped head syndrome and rheumatic diseases, particularly systemic sclerosis. The case we describe concerns a 74-year-old woman with dropped-head syndrome associated to Systemic sclerosis and pulmonary hypertension in absence of myositis signs.

    This article looks back in time to see where the foundational basis for the understanding of amyotrophic lateral sclerosis originated. This foundation was created primarily in France by Jean-Martin Charcot and his fellow countrymen and disciples, along with key contributions from early clinicians in England and Germany. The early work on amyotrophic lateral sclerosis provides a useful foundation for today's clinicians with respect to tying together genetic and biologic aspects of the disorder that have been discovered over the past few decades.

    An overall aim of treatment in multiple sclerosis is to lower the negative impact of the disease on functioning and quality of life of patients. Therefore, a measurement of functioning and quality of life should be included in the evaluation of the effectiveness of treatment. In this paper the most commonly used quality of life questionnaires, either generic and specific, were presented. Information about clinical and functional status is useful in the interpretation of the quality of life assessment results. Because of that, instruments for the assessment of depression, cognitive functions, functional ability and fatigue in multiple sclerosis were also described. PMID:21254730

    Multiple beneficial effects have been proposed lately for cannabinoids in different clinical situations. Among them, it has been postulated they would control symptoms of multiple sclerosis. However, there is no consensus about their real clinical role. To answer this question, we searched in Epistemonikos database, which is maintained by screening multiple databases. We identified 25 systematic reviews including 35 studies overall, of which 26 were randomized trials. We extracted data, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded cannabinoids in multiple sclerosis do not reduce spasticity or pain, and are probably associated to frequent adverse effects.

    Vasculopathy in systemic sclerosis is a severe, in many cases irreversible, manifestation that can lead to amputation. While the classical clinical manifestations of the disease have to do with the involvement of microcirculation, proximal vessels of upper and lower limbs can also be affected. This involvement of large vessels may be related to systemic sclerosis, vasculitis or atherosclerotic, and the differential diagnosis is not easy. To conduct a proper and early diagnosis, it is essential to start prompt appropriate treatment. In this review, we examine the involvement of large vessels in scleroderma, an understudied manifestation with important prognostic and therapeutic implications.

    Malignancy is associated with systemic sclerosis in between 3.6 and 10.7% of patients diagnosed with systemic sclerosis. The diagnosis of systemic sclerosis may occur before, concurrent with, or after the diagnosis of malignancy. All published reports of malignancy with systemic sclerosis are reviewed. Lung cancer is the most frequent type of cancer seen in patients with systemic sclerosis, followed by breast cancer. Risk factors for the development of malignancy in patients with systemic sclerosis are female gender, increased age, and diffuse systemic sclerosis. Autoantibodies such as anticentromere and antitopoisomerase I are inconsistent in their risk for developing malignancy. Vigilance is recommended in this group of patients based on their increased risk of developing cancer.

    Constipation, obstructed defecation, and fecal incontinence are frequent complaints in multiple sclerosis. The literature on the pathophysiological mechanisms underlying these disorders is scant. Using anorectal manometry, we compared the anorectal function in patients with and without multiple sclerosis. 136 patients referred from our Center for Multiple Sclerosis to the Coloproctology Outpatient Clinic, between January 2005 and December 2011, were enrolled. The patients were divided into four groups: multiple sclerosis patients with constipation (group A); multiple sclerosis patients with fecal incontinence (group B); non-multiple sclerosis patients with constipation (group C); non-multiple sclerosis patients with fecal incontinence (group D). Anorectal manometry was performed to measure: resting anal pressure; maximum squeeze pressure; rectoanal inhibitory reflex; filling pressure and urge pressure. The difference between resting anal pressure before and after maximum squeeze maneuvers was defined as the change in resting anal pressure calculated for each patient.

    Imbalances in T cell subpopulations have been reported in multiple sclerosis (MS). In the present study of 31 MS patients, the percentage of T cells with Fc receptors for IgG (Tg) was found to be increased in patients with chronic progressive disease, and another T cell subset binding to the Raji B lymphoid cell line was decreased. An inverse correlation (r = -0.675; < 95% confidence limit) was found between these two subsets, suggesting that they vary inversely in MS. The mitogenic responses of MS mononuclear cells, isolated T cells, and recombinet T and non-T cells to the lectins phytohemagglutinin and pokeweek mitogen (PWM) did not differ from those of normal cells. However, more immunoglobulin (Ig)-producing cells were generated in a PWM-driven system with cells from MS patients than with cells from age-matched controls (p < 0.05). Autologous recombination of separated T and non-T cells did not significantly modify these results. T cells from MS patients added to B cells from normal controls exerted an effect that was related to their percentage of Tg cells; that is, values above 15% were associated with a suppression of Ig production, whereas for Tg values below 12%, a helper effect or no modification was observed. These results suggest that changes in T cell subsets in MS are related to changes in functional ability to modulate Ig production by normal B cells. However, MS B cells partly escape regulation by their own T cells, suggesting an associated B cell hyperactivity.

  7. Targeted Therapy in Systemic Sclerosis

    Targeted therapies use an understanding of the pathophysiology of a disease in an individual patient. Although targeted therapy for systemic sclerosis (SSc, scleroderma) has not yet reached the level of patient-specific treatments, recent developments in the understanding of the global pathophysiology of the disease have led to new treatments based on the cells and pathways that have been shown to be involved in the disease pathogenesis. The presence of a B cell signature in skin biopsies has led to the trial of rituximab, an anti-CD20 antibody, in SSc. The well-known properties of transforming growth factor (TGF)-β in promoting collagen synthesis and secretion has led to a small trial of fresolimumab, a human IgG4 monoclonal antibody capable of neutralizing TGF-β. Evidence supporting important roles for interleukin-6 in the pathogenesis of SSc have led to a large trial of tocilizumab in SSc. Soluble guanylate cyclase (sGC) is an enzyme that catalyzes the production of cyclic guanosine monophosphate (cGMP) upon binding of nitric oxide (NO) to the sGC molecule. Processes such as cell growth and proliferation are regulated by cGMP. Evidence that sGC may play a role in SSc has led to a trial of riociguat, a molecule that sensitizes sGC to endogenous NO. Tyrosine kinases (TKs) are involved in a wide variety of physiologic and pathological processes including vascular remodeling and fibrogenesis such as occurs in SSc. This has led to a trial of nintedanib, a next-generation tyrosine-kinase (TK) inhibitor which targets multiple TKs, in SSc. PMID:27824545

    The question whether dietary habits and lifestyle have influence on the course of multiple sclerosis (MS) is still a matter of debate, and at present, MS therapy is not associated with any information on diet and lifestyle. Here we show that dietary factors and lifestyle may exacerbate or ameliorate MS symptoms by modulating the inflammatory status of the disease both in relapsing-remitting MS and in primary-progressive MS. This is achieved by controlling both the metabolic and inflammatory pathways in the human cell and the composition of commensal gut microbiota. What increases inflammation are hypercaloric Western-style diets, characterized by high salt, animal fat, red meat, sugar-sweetened drinks, fried food, low fiber, and lack of physical exercise. The persistence of this type of diet upregulates the metabolism of human cells toward biosynthetic pathways including those of proinflammatory molecules and also leads to a dysbiotic gut microbiota, alteration of intestinal immunity, and low-grade systemic inflammation. Conversely, exercise and low-calorie diets based on the assumption of vegetables, fruit, legumes, fish, prebiotics, and probiotics act on nuclear receptors and enzymes that upregulate oxidative metabolism, downregulate the synthesis of proinflammatory molecules, and restore or maintain a healthy symbiotic gut microbiota. Now that we know the molecular mechanisms by which dietary factors and exercise affect the inflammatory status in MS, we can expect that a nutritional intervention with anti-inflammatory food and dietary supplements can alleviate possible side effects of immune-modulatory drugs and the symptoms of chronic fatigue syndrome and thus favor patient wellness.

    Hypothalamic involvement is a rare condition in patients with multiple sclerosis (MS). We report two patients with a long history of MS who presented with severe acute hypothermia with associated thrombocytopenia and elevated transaminase levels. Several cases of hypothermia or hyperthermia in patients with MS have been reported in the literature. They could be linked with hypothalamic lesions, in particular in the pre-optic area. However, other anatomical locations seem to be involved in thermoregulation and can be affected by MS. Besides, some cases of syndrome of inappropriate antidiuretic hormone secretion have been reported in patients with MS. Finally, some sleep disorders, particularly hypersomnia or narcolepsy, could be related to hypothalamic lesions, through the fall in hypocretin-1 in the cerebrospinal fluid. Hypocretin-1 is a neuropeptide that is secreted by some hypothalamic cells. It plays a role in the sleep-awake rhythm. We report one patient with narcolepsy and cataplexy before the first symptoms of MS appeared. Hypothalamic signs are rare in MS. However, several series of autopsies have shown a high frequency of demyelinating lesions in the hypothalamic area. Among these lesions, the proportion of active lesions seems elevated. Yet only few of them have a clinical or biological translation such as thermoregulation dysfunction, sleep disorders or natremia abnormalities. Thus, it seems unlikely that inflammatory hypothalamic lesions alone, even when bilateral, could be the explanation of these signs. A sufficient number of inflammatory demyelinating lesions, which we can observe in patients with a long history of MS and an already severe disability, is probably necessary to develop such a rare symptomatology. Hypothalamic signs might be a factor of poor prognosis for the disease course and progression of the disability.

    Objective: To quantify the magnitude of deficits in theory of mind (ToM) and facial emotion recognition among patients with multiple sclerosis (MS) relative to healthy controls. Methods: An electronic database search of Ovid MEDLINE, PsycINFO, and Embase was conducted from inception to April 1, 2016. Eligible studies were original research articles published in peer-reviewed journals that examined ToM or facial emotion recognition among patients with a diagnosis of MS and a healthy control comparison group. Data were independently extracted by 2 authors. Effect sizes were calculated using Hedges g. Results: Twenty-one eligible studies were identified assessing ToM (12 studies) and/or facial emotion recognition (13 studies) among 722 patients with MS and 635 controls. Deficits in both ToM (g = −0.71, 95% confidence interval [CI] −0.88 to −0.55, p < 0.001) and facial emotion recognition (g = −0.64, 95% CI −0.81 to −0.47, p < 0.001) were identified among patients with MS relative to healthy controls. The largest deficits were observed for visual ToM tasks and for the recognition of negative facial emotional expressions. Older age predicted larger emotion recognition deficits. Other cognitive domains were inconsistently associated with social cognitive performance. Conclusions: Social cognitive deficits are an overlooked but potentially important aspect of cognitive impairment in MS with potential prognostic significance for social functioning and quality of life. Further research is required to clarify the longitudinal course of social cognitive dysfunction, its association with MS disease characteristics and neurocognitive impairment, and the MS-specific neurologic damage underlying these deficits.

    Objective To examine the demographic and clinical characteristics of systemic sclerosis (SSc) patients without antinuclear antibodies (ANA) compared to ANA positive patients. Methods SSc patients enrolled in the Scleroderma Family Registry and DNA Repository were included. Relevant demographic and clinical data were entered by participating sites or obtained by chart review. ANA and SSc related antibodies were determined in all investigated patients using commercially available kits at our laboratories. Results This study included 3249 patients, of whom 208 (6.4%) were ANA negative. The proportion of male patients was higher in the ANA negative group (OR 1.65; p=0.008). ANA negative patients experienced less vasculopathic manifestations of SSc. The percent predicted diffusing capacity of carbon monoxide (DLco) was higher in ANA negative patients (p=0.03). Pulmonary arterial hypertension (PAH) per right heart catheterization was less common in the ANA negative group (OR= 0.28; p=0.03). Furthermore, patients with negative ANA had a lower prevalence of telangiectasias and digital ulcers/pits (OR= 0.59; p=0.03 and OR=0.38; p=0.01, respectively). Although diffuse cutaneous involvement was more common, the modified Rodnan Skin Score (mRSS) was lower in the ANA negative group (2.4 points lower, p=0.05). Furthermore, they experienced more malabsorption (p=0.05). There was no difference in the frequency of pulmonary fibrosis or scleroderma renal crisis. All-cause mortality was not different between the two groups (p=0.28). Conclusions In conclusion, the results of this study suggest that SSc patients who are ANA negative constitute a distinct subset of SSc with less vasculopathy (less PAH, digital ulcers and fewer telangiectasias), a greater proportion of males and possibly, more frequent lower gastrointestinal involvement.

    2014-01-01

    Histochemical and MRI studies have demonstrated that MS (multiple sclerosis) patients have abnormal deposition of iron in both gray and white matter structures. Data is emerging indicating that this iron could partake in pathogenesis by various mechanisms, e.g., promoting the production of reactive oxygen species and enhancing the production of proinflammatory cytokines. Iron chelation therapy could be a viable strategy to block iron-related pathological events or it can confer cellular protection by stabilizing hypoxia inducible factor 1α, a transcription factor that normally responds to hypoxic conditions. Iron chelation has been shown to protect against disease progression and/or limit iron accumulation in some neurological disorders or their experimental models. Data from studies that administered a chelator to animals with experimental autoimmune encephalomyelitis, a model of MS, support the rationale for examining this treatment approach in MS. Preliminary clinical studies have been performed in MS patients using deferoxamine. Although some side effects were observed, the large majority of patients were able to tolerate the arduous administration regimen, i.e., 6–8 h of subcutaneous infusion, and all side effects resolved upon discontinuation of treatment. Importantly, these preliminary studies did not identify a disqualifying event for this experimental approach. More recently developed chelators, deferasirox and deferiprone, are more desirable for possible use in MS given their oral administration, and importantly, deferiprone can cross the blood–brain barrier. However, experiences from other conditions indicate that the potential for adverse events during chelation therapy necessitates close patient monitoring and a carefully considered administration regimen.

    Among other symptoms, multiple sclerosis can also produce symptoms of affective and cognitive disorders. The majority of patients have certain cognitive dysfunctions, and the' most common affective disorder is reactive depression. The aim of the study was to determine the correlation of the Mini-Mental State (MMS) and Beck Depression Inventory (BDI) scale scores with the Expanded Disability Status Scale (EDSS) score in patients with multiple sclerosis treated at University Department of Neurology, Sarajevo University Clinical Center in Sarajevo. We evaluated 50 randomly selected patients with various types of multiple sclerosis using the MMS, BDI and EDSS instruments. The study included 33 women and 17 men (66% : 34%), mean age 40.74 years (SD 9.236). The mean value of EDSS score was 3.98, ranging from 1.0 to 8.5 in women and from 1.0 to 6.5 in men. BDI scale scores showed a mean value of 12.56. The mean MMS score in baseline sample was 26.88. Statistically significant positive correlation was found between age and EDSS score, and negative correlation between EDSS and MMS, as well as between BDI and MMS. Study results indicated older patients with multiple sclerosis to have a higher EDSS score with more pronounced cognitive disturbances. There was no statistically significant correlation between EDSS score and depression.

    Abstract The deleterious effect of fructose, which is increasingly incorporated in many beverages, dairy products, and processed foods, has been described; fructose malabsorption has thus been reported in up to 2.4% of healthy subjects, leading to digestive clinical symptoms (eg, pain, distension, diarrhea). Because digestive involvement is frequent in patients with systemic sclerosis (SSc), we hypothesized that fructose malabsorption could be responsible for intestinal manifestations in these patients. The aims of this prospective study were to: determine the prevalence of fructose malabsorption, in SSc; predict which SSc patients are at risk of developing fructose malabsorption; and assess the outcome of digestive symptoms in SSc patients after initiation of standardized low-fructose diet. Eighty consecutive patients with SSc underwent fructose breath test. All SSc patients also completed a questionnaire on digestive symptoms, and a global symptom score (GSS) was calculated. The prevalence of fructose malabsorption was as high as 40% in SSc patients. We also observed a marked correlation between the presence of fructose malabsorption and: higher values of GSS score of digestive symptoms (P = 0.000004); and absence of delayed gastric emptying (P = 0.007). Furthermore, in SSc patients with fructose malabsorption, the median value of GSS score of digestive symptoms was lower after initiation of standardized low-fructose diet (4 before vs. 1 after; P = 0.0009). Our study underscores that fructose malabsorption often occurs in SSc patients. Our findings are thus relevant for clinical practice, highlighting that fructose breath test is a helpful, noninvasive method by: demonstrating fructose intolerance in patients with SSc; and identifying the group of SSc patients with fructose intolerance who may benefit from low-fructose diet. Interestingly, because the present series also shows that low-fructose diet resulted in a marked decrease of gastrointestinal

    Introduction Pulmonary function abnormalities have been described in multiple sclerosis including reductions in forced vital capacity (FVC) and cough but the time course of this impairment is unknown. Peak cough flow (PCF) is an important parameter for patients with respiratory muscle weakness and a reduced PCF has a direct impact on airway clearance and may therefore increase the risk of respiratory tract infections. Lung volume recruitment is a technique that improves PCF by inflating the lungs to their maximal insufflation capacity. Objectives Our goals were to describe the rate of decline of pulmonary function and PCF in patients with multiple sclerosis and describe the use of lung volume recruitment in this population. Methods We reviewed all patients with multiple sclerosis referred to a respiratory neuromuscular rehabilitation clinic from February 1999 until December 2010. Lung volume recruitment was attempted in patients with FVC <80% predicted. Regular twice daily lung volume recruitment was prescribed if it resulted in a significant improvement in the laboratory. Results There were 79 patients included, 35 of whom were seen more than once. A baseline FVC <80% predicted was present in 82% of patients and 80% of patients had a PCF insufficient for airway clearance. There was a significant decline in FVC (122.6 mL/y, 95% CI 54.9–190.3) and PCF (192 mL/s/y, 95% 72–311) over a median follow-up time of 13.4 months. Lung volume recruitment was associated with a slower decline in FVC (p<0.0001) and PCF (p = 0.042). Conclusion Pulmonary function and cough decline significantly over time in selected patients with multiple sclerosis and lung volume recruitment is associated with a slower rate of decline in lung function and peak cough flow. Given design limitations, additional studies are needed to assess the role of lung volume recruitment in patients with multiple sclerosis. PMID:23383293

    Motor neuron disease (MND) is used in this paper as the generic label, encompassing the clinical variants of amyotrophic lateral sclerosis (ALS), progressive myelopathic muscular atrophy (PMMA), and progressive bulbar palsy (PBP). ALS is limited to instances of anterior horn cell plus pyramidal tract involvement. When only anterior horn cell lesions are inferred, either PMMA or PBP is used, depending on the levels of involvement; when both cord and brain stem are affected. PBP is the designation. Mortality data on MND have been available for a number of countries since 1949. The coding used under international rules has varied considerably over this interval. Before 1969, hereditary muscular atrophies were included. Since 1979, no subdivision by type of MND is possible. International death rates for MND have all been rather close to 1 per 100,000 population per year, though perhaps nearer to 1.4 on the average in recent years. There has been an increasing proportion of MND deaths coded to ALS between 1949 and 1977. There is no notable geographic variation among countries, nor within countries such as the U.S. and Denmark. A slight upward trend in death rates over time in the U.S. is matched by a slight decrease in Denmark. Death rates from all sources indicate a male preponderance for ALS or MND as a whole, at about 1.5 to 1, male to female. There is also a consistent predilection by age, with few deaths under age 50 or so and a clear maximum in age-specific death rates at about age 70. This holds for both sexes. In the U.S., there is also a white-nonwhite difference, with a ratio of about 1.6:1 but with age and sex differences similar to whites. Average annual incidence rates from among white occidental populations range mostly between 0.6 and 1.8 per 100,000 population for MND and about 0.8 and 1.5 per 100,000 for ALS. Again a male predilection is seen. There is a clear maximum in age-specific incidence rates at about age 65 in all surveys except that of

    T suppressor cell function and phenotype are abnormal in patients with multiple sclerosis, especially during the chronic progressive phase but the sub-populations defined by mitogen stimulation and serological methods may not be identical. In this study, involving 45 patients with multiple sclerosis and 33 controls, there was no correlation between T suppressor function and CD8 cell phenotype in patients with multiple sclerosis or in controls. These phenotypic and functional studies cannot therefore be used interchangeably in the assessment of patients with multiple sclerosis since they provide different information about lymphocyte subpopulations.

Tumefactive demyelinating lesions pose a diagnostic challenge because they can mimic tumors and abscesses and because they can be caused by a heterogeneous range of disorders. This article reviews the recent literature on the clinical presentation; radiographic features; prognosis; and management of tumefactive demyelinating lesions in multiple sclerosis, acute demyelinating encephalomyelitis, neuromyelitis optica, and the rare variants of multiple sclerosis including Schilder's disease, Marburg acute multiple sclerosis, and Balo's concentric sclerosis.

    Systemic sclerosis is a rare connective tissue disease, distinctive features of which are fibrosis and microangiopathy. The esophagus is one of the most commonly involved internal organs. Most patients experience dysphagia, difficulties in swallowing and gastro-esophageal reflux. However, in up to one third of cases, the initial onset of esophageal disease may be clinically silent. There are several diagnostic modalities available for assessing both morphological and functional abnormalities of the esophagus. If structural abnormalities are suspected, endoscopy is the method of choice. Functional evaluation is best achieved with manometry. Both endoscopy and manometry are invasive techniques, with low patient acceptance. Barium-contrast study is well tolerated, but qualitative assessment of functional abnormalities is imprecise. Esophageal scintigraphy is an easy, non-invasive, sensitive and specific diagnostic modality. It can detect esophageal dysfunction even in asymptomatic patients. In patients already diagnosed with systemic sclerosis, scintigraphy is useful in evaluating severity and progression of the disease. PMID:27994270

     Multiple sclerosis is a neuroimmunological disease in which etiologic agents have not been identified yet. The etiology of MS is complex in its nature and may involve many different agents acting simultaneously or in a cascade manner leading to the development of the disease. The causes of MS development were sought among the factors associated with HLA and TCR genes and human endogenous retroviruses (HERV). Environmental factors such as bacterial, fungal and viral infections as well as potential participation of vitamin D in the pathogenesis of the disease have also been examined. The current state of knowledge concerning potential factors participating in the etiopathogenesis of multiple sclerosis has been reviewed in this paper.

    2013-09-01

    Teriflunomide is an oral, once-daily disease-modifying therapy (DMT) approved in the USA, Australia, and Argentina for the treatment of relapsing forms of multiple sclerosis (RMS). Teriflunomide reversibly limits the expansion of activated T and B cells associated with the inflammatory process purportedly involved in multiple sclerosis pathogenesis, while preserving lymphocytes for routine immune surveillance. In an extensive clinical development program, teriflunomide demonstrated consistent benefits on both clinical and magnetic resonance imaging outcomes. In long-term studies, teriflunomide treatment was associated with low rates of relapse and disability progression for up to 8 years. The safety profile of teriflunomide has been well characterized, with adverse events generally mild to moderate in nature and infrequently leading to permanent treatment discontinuation. The evidence reviewed here indicates that teriflunomide is an effective addition to the current DMTs used to treat RMS.

    Since their introduction in medical therapy, in the last quarter of the 20th century, monoclonal antibodies have gained an increasing importance in the treatment of various diseases. Neurology has been one of the medical specialties benefiting of the therapeutic potential of these monoclonal antibodies and certain neurological conditions may now contain such drugs in their therapeutic algorithms. Multiple sclerosis is one of these diseases and, in addition to the monoclonal antibodies already licensed for clinical use, several others are in development for future utilization in this specific area. The future will certainly pass through this kind of drugs and, in this article, a review of the most relevant data related to monoclonal antibodies already in use and also in clinical development for multiple sclerosis treatment will be performed.

However, vascular treatment options are well established, the body of evidence for the efficacy of immunomodulatory approaches is increasing, and now at least one hopeful substance that may directly interfere with fibrosis is being tested. Although we still wait for important breakthroughs, there is grounds for hope that better therapeutic options will be available in the near future.

    Aim: This study was planned with the aim of retrospectively reviewing the clinical and laboratory findings and therapies of our patients diagnosed with tuberous sclerosis and redefining the patients according to the diagnostic criteria revised by the 2012 International Tuberous Sclerosis Complex Consensus Group and comparing them with the literature. Materials and Method: Twenty patients diagnosed with tuberous sclerosis complex in the Pediatric Neurology Clinic were examined retrospectively in terms of clinical findings and therapies. The diagnoses were compared again according to 1998 and 2012 criteria. Results: It was observed that the complaint at presentation was seizure in 17 of 20 patients and hypopigmented spots on the skin in 3 of 20 patients. On the initial physical examination, findings related with the disease were found in the skin in 17 of the patients, in the eye in 5, in the kidneys in 7 and in the brain with imaging in 17. No cardiac involvement was observed in the patients. Infantile spasm was observed in 7 of the patients who presented because of seizure (n=17), partial seizure was observed in 7 and multiple seizure types were observed in 3. It was found that sirolimus treatment was given to 9 of 20 patients because of different reasons, 7 of these 9 patients had epileptic seizures and sirolimus treatment had no effect on epileptic seizures. According to 2012 diagnostic criteria, no marked change occured in the diagnoses of our patients. Conclusions: It was observed that the signs and symptoms of our patients were compatible with the literature. Molecular genetic examination was planned for the patients who were being followed up because of probable tuberous sclerosis complex. It was observed that sirolimus treatment had no marked effect on the seizure frequency of our patients. PMID:26078697

    Objectives Microarray produces a large amount of gene expression data, containing various biological implications. The challenge is to detect a panel of discriminative genes associated with disease. This study proposed a robust classification model for gene selection using gene expression data, and performed an analysis to identify disease-related genes using multiple sclerosis as an example. Materials and methods Gene expression profiles based on the transcriptome of peripheral blood mononuclear cells from a total of 44 samples from 26 multiple sclerosis patients and 18 individuals with other neurological diseases (control) were analyzed. Feature selection algorithms including Support Vector Machine based on Recursive Feature Elimination, Receiver Operating Characteristic Curve, and Boruta algorithms were jointly performed to select candidate genes associating with multiple sclerosis. Multiple classification models categorized samples into two different groups based on the identified genes. Models’ performance was evaluated using cross-validation methods, and an optimal classifier for gene selection was determined. Results An overlapping feature set was identified consisting of 8 genes that were differentially expressed between the two phenotype groups. The genes were significantly associated with the pathways of apoptosis and cytokine-cytokine receptor interaction. TNFSF10 was significantly associated with multiple sclerosis. A Support Vector Machine model was established based on the featured genes and gave a practical accuracy of ∼86%. This binary classification model also outperformed the other models in terms of Sensitivity, Specificity and F1 score. Conclusions The combined analytical framework integrating feature ranking algorithms and Support Vector Machine model could be used for selecting genes for other diseases. PMID:24932510

    Multiple sclerosis is a chronic inflammatory disease of the central nervous system, associated with demyelination and neurodegeneration. The mechanisms of tissue injury are currently poorly understood, but recent data suggest that mitochondrial injury may play an important role in this process. Since mitochondrial injury can be triggered by reactive oxygen and nitric oxide species, we analysed by immunocytochemistry the presence and cellular location of oxidized lipids and oxidized DNA in lesions and in normal-appearing white matter of 30 patients with multiple sclerosis and 24 control patients without neurological disease or brain lesions. As reported before in biochemical studies, oxidized lipids and DNA were highly enriched in active multiple sclerosis plaques, predominantly in areas that are defined as initial or 'prephagocytic' lesions. Oxidized DNA was mainly seen in oligodendrocyte nuclei, which in part showed signs of apoptosis. In addition, a small number of reactive astrocytes revealed nuclear expression of 8-hydroxy-d-guanosine. Similarly, lipid peroxidation-derived structures (malondialdehyde and oxidized phospholipid epitopes) were seen in the cytoplasm of oligodendrocytes and some astrocytes. In addition, oxidized phospholipids were massively accumulated in a fraction of axonal spheroids with disturbed fast axonal transport as well as in neurons within grey matter lesions. Neurons stained for oxidized phospholipids frequently revealed signs of degeneration with fragmentation of their dendritic processes. The extent of lipid and DNA oxidation correlated significantly with inflammation, determined by the number of CD3 positive T cells and human leucocyte antigen-D expressing macrophages and microglia in the lesions. Our data suggest profound oxidative injury of oligodendrocytes and neurons to be associated with active demyelination and axonal or neuronal injury in multiple sclerosis.

    Purpose of review Systemic sclerosis (SSc), an autoimmune disease of unknown origin, is characterized by progressive fibrosis that can affect all organs of the body. To date, there are no effective therapies for the disease. This paucity of treatment options is primarily due to limited understanding of the processes that initiate and promote fibrosis in general and a lack of animal models that specifically emulate the chronic nature of systemic sclerosis. Most models capitulate acute injury-induced fibrosis in specific organs. Regardless of the model however, a major outstanding question in the field is the cellular origin of fibrosing cells. Recent findings A multitude of origins have been proposed in a variety of tissues, including resident tissue stroma, fibrocytes, pericytes, adipocytes, epithelial cells, and endothelial cells. Developmentally derived fibroblast lineages have recently been elucidated with fibrosing potential in injury models. Increasing data supports the pericyte as a fibrosing cell origin in diverse fibrosis models and adipocytes have recently been proposed. Fibrocytes, epithelial cells, and endothelial cells have been examined, though data does not as strongly support these possible origins. Summary In this review, we discuss recent evidence arguing in favor of and against proposed origins of fibrosing cells in diverse models of fibrosis. We highlight outstanding controversies and propose how future research may elucidate how fibrosing cells arise and what processes can be targeted in order to treat systemic sclerosis. PMID:26352735

    Systemic sclerosis is a collagen disease with high frequency of oesophageal affection, specially if we use manometry as an evaluation method that has a high rate of clinic complication in high rate of patients. The aim of the study was to evaluate the prevalence of the oesophageal affection through the clinical, radiological, endoscopical and manometrical studies and to compare the results with other authors. Between January 1978 and February 1993, we evaluated 101 patients with different clinical types of scleroderma 89 females and 12 males with ages between 16-83 (mean: 49, 19 years). In order to determine systemic sclerosis diagnosis following Masi Rodman criterion's we found from 101 cases 83 had dysphagia (82.2%) motor 66 (65%) organic 17 (34.7%) GER was seem in 41 cases (40.5%). According to Heitz's radiological classification: I: 26 patients (25%) II: 58 patients (52.4%) III: 19 patients (18.8%) IV: 17 patients (16.9%).

    There are two nationwide population-based registers for multiple sclerosis (MS) in Denmark. The oldest register is The Danish Multiple Sclerosis Registry (DMSR), which is an epidemiological register for estimation of prevalence and incidence of MS and survival, and for identifying exposures earlier in life that may affect the risk of MS. This register has no systematic follow-up data except for survival. The DMSR has over the years published nationwide incidence- and prevalence data from Denmark and has been involved in a number of 'historical prospective' studies to elucidate the association between a number of different environmental exposures in the past and the subsequent risk of MS. Some of these studies have been able to exonerate suspected risk factors. The other register, the nationwide Danish Multiple Sclerosis Treatment Register, is a follow-up register for all patients who have received disease-modifying treatments since 1996. It has, in particular, contributed to the knowledge of the role of antibodies against the biological drugs used for the treatment of MS.

    Using scanning electronic microscopy of peripheral blood platelets in 32 patients with amyotrophic lateral sclerosis (ALS) and 6 patients with multiple sclerosis (MS), platelets activation, emerging in pseudopodiums formation, aggregation and lysis, was found. Platelets activation was more pronounced in ALS than in MS. It was most markedly seen for quantitative evaluation of the above traits. The features of platelet activation found in the study support the evidence for considering ALS as a systemic disorder being characterized by a broad spectrum of alterations of biological processes.

    The Genes and Environment in Multiple Sclerosis project establishes a platform to investigate the events leading to multiple sclerosis (MS) in at-risk individuals. It has recruited 2,632 first-degree relatives from across the USA. Using an integrated genetic and environmental risk score, we identified subjects with twice the MS risk when compared to the average family member, and we report an initial incidence rate in these subjects that is 30 times greater than that of sporadic MS. We discuss the feasibility of large-scale studies of asymptomatic at-risk subjects that leverage modern tools of subject recruitment to execute collaborative projects.

    Jasmonates (JAs) regulate a wide range of plant defense and development processes. The bioactive JA is perceived by its receptor COI1 to trigger the degradation of JASMONATE ZIM-DOMAIN (JAZ) proteins and subsequently derepress the JAZ-repressed transcription factors for activation of expression of JA-responsive genes. So far, (+)-7-iso-JA-l-Ile has been the only identified endogenous bioactive JA molecule. Here, we designed coronafacic acid (CFA) conjugates with all the amino acids (CFA-AA) to mimic the JA amino acid conjugates, and revealed that (+)-7-iso-JA-Leu, (+)-7-iso-JA-Val, (+)-7-iso-JA-Met, and (+)-7-iso-JA-Ala are new endogenous bioactive JA molecules. Furthermore, our studies uncover the general characteristics for all the bioactive JA molecules, and provide a new strategy to synthetically generate novel active JA molecules.

    Epidemiologic evidence indicates that the outbreak of 30-40 cases of multiple sclerosis and other demyelinating syndromes in Galion, Ohio, USA, during 1982-1985 was related to an excess concentration of heavy-metal wastes, especially of cadmium and chromium in sewage and river water. Both multiple sclerosis and myasthenia gravis were diagnosed by board-certified neurologists.

    In recent years the approval of new substances has led to a substantial increase in the number of course-modifying immunotherapies available for multiple sclerosis. Therapy conversion therefore represents an increasing challenge. The treatment options sometimes show complex adverse effect profiles and necessitate a long-term and comprehensive monitoring. This article presents an overview of therapy conversion of immunotherapies for multiple sclerosis in accordance with the recommendations of the Disease-Related Competence Network for Multiple Sclerosis and the German Multiple Sclerosis Society as well as the guidelines on diagnostics and therapy for multiple sclerosis of the German Society of Neurology and the latest research results. At the present point in time it should be noted that no studies have been carried out for most of the approaches for therapy conversion given here; however, the recommendations are based on theoretical considerations and therefore correspond to recommendations at the level of expert consensus, which is currently essential for the clinical daily routine.

  16. High-fat and ketogenic diets in amyotrophic lateral sclerosis.

    PubMed

    Paganoni, Sabrina; Wills, Anne-Marie

    2013-08-01

    Amyotrophic lateral sclerosis is a fatal neurodegenerative disease. Epidemiologic data suggest that malnutrition is a common feature in amyotrophic lateral sclerosis and being overweight or obese confers a survival advantage in this patient population. In amyotrophic lateral sclerosis mouse models, a high-fat diet has been shown to lead to weight gain and prolonged survival. However, little research has been conducted to test whether nutritional interventions might ameliorate the disease course in humans. Here we review the currently available evidence supporting the potential role of dietary interventions as a therapeutic tool for amyotrophic lateral sclerosis. Ultimately, determining whether a high-fat or ketogenic diet could be beneficial in amyotrophic lateral sclerosis will require large randomized, placebo-controlled clinical trials.

    2016-02-01

    Systemic sclerosis is a devastating multisystem rheumatologic condition that is characterized by autoimmunity, tissue fibrosis, obliterative vasculopathy and inflammation. Clinical presentation and course of the condition vary greatly, which complicates both diagnosis and corresponding treatment. In this regard, recent advances in disease understanding, both clinically and biochemically, have led to newer classification criteria for systemic sclerosis that are more inclusive than ever before. Still, significant disease modifying therapies do not yet exist for most patients. Therefore, organ-based management strategies are employed and research has been directed within this paradigm focusing on either the most debilitating symptoms, such as Raynaud's phenomenon, digital ulcers and cutaneous sclerosis, or life-threatening organ involvement such as interstitial lung disease and pulmonary arterial hypertension. The current trends in systemic sclerosis diagnosis, evidence-based treatment recommendations and potential future directions in systemic sclerosis treatment are discussed.

    Background: There is evidence of the benefits of exercise training in multiple sclerosis (MS); however, few studies have been conducted in individuals with progressive MS and severe mobility impairment. A potential exercise rehabilitation approach is total-body recumbent stepper training (TBRST). We evaluated the safety and participant-reported experience of TBRST in people with progressive MS and compared the efficacy of TBRST with that of body weight–supported treadmill training (BWSTT) on outcomes of function, fatigue, and health-related quality of life (HRQOL). Methods: Twelve participants with progressive MS (Expanded Disability Status Scale scores, 6.0–8.0) were randomized to receive TBRST or BWSTT. Participants completed three weekly sessions (30 minutes) of exercise training for 12 weeks. Primary outcomes included safety assessed as adverse events and patient-reported exercise experience assessed as postexercise response and evaluation of exercise equipment. Secondary outcomes included the Multiple Sclerosis Functional Composite, the Modified Fatigue Impact Scale, and the Multiple Sclerosis Quality of Life–54 questionnaire scores. Assessments were conducted at baseline and after 12 weeks. Results: Safety was confirmed in both exercise groups. Participants reported enjoying both exercise modalities; however, TBRST was reviewed more favorably. Both interventions reduced fatigue and improved HRQOL (P ≤ .05); there were no changes in function. Conclusions: Both TBRST and BWSTT seem to be safe, well tolerated, and enjoyable for participants with progressive MS with severe disability. Both interventions may also be efficacious for reducing fatigue and improving HRQOL. TBRST should be further explored as an exercise rehabilitation tool for patients with progressive MS.

  19. Evaluating Walking in Patients with Multiple Sclerosis

    PubMed Central

    Bennett, Susan

    2011-01-01

    Walking limitations are among the most visible manifestations of multiple sclerosis (MS). Regular walking assessments should be a component of patient management and require instruments that are appropriate from the clinician's and the patient's perspectives. This article reviews frequently used instruments to assess walking in patients with MS, with emphasis on their validity, reliability, and practicality in the clinical setting. Relevant articles were identified based on PubMed searches using the following terms: “multiple sclerosis AND (walking OR gait OR mobility OR physical activity) AND (disability evaluation)”; references of relevant articles were also searched. Although many clinician- and patient-driven instruments are available, not all have been validated in MS, and some are not sensitive enough to detect small but clinically important changes. Choosing among these depends on what needs to be measured, psychometric properties, the clinical relevance of results, and practicality with respect to space, time, and patient burden. Of the instruments available, the clinician-observed Timed 25-Foot Walk and patient self-report 12-Item Multiple Sclerosis Walking Scale have properties that make them suitable for routine evaluation of walking performance. The Dynamic Gait Index and the Timed Up and Go test involve other aspects of mobility, including balance. Tests of endurance, such as the 2- or 6-Minute Walk, may provide information on motor fatigue not captured by other tests. Quantitative measurement of gait kinetics and kinematics, and recordings of mobility in the patient's environment via accelerometry or Global Positioning System odometry, are currently not routinely used in the clinical setting.

    2016-01-01

    It is recognized that neuropsychiatric conditions are overrepresented in amyotrophic lateral sclerosis (ALS) patient kindreds and psychiatric symptoms may precede the onset of motor symptoms. Using a hospital record linkage database, hospitalization with a diagnosis of schizophrenia, bipolar disorder, depression, or anxiety was significantly associated with a first diagnosis of ALS within the following year. This is likely to specifically reflect the clinicopathological overlap of ALS with frontotemporal dementia. A diagnosis of depression was significantly associated with a first record of ALS ≥5 years later, in keeping with growing evidence for major depressive disorder as an early marker of cerebral neurodegeneration.

    2000-01-01

    The usefulness of evoked potentials (EPs) in the diagnosis of multiple sclerosis is limited by its relatively low sensitivity to subclinical lesions. However, they are still a good tool to assess the integrity of afferent and efferent pathways and to quantify the severity of white matter involvement. Transversal and longitudinal studies have demonstrated good correlation between EP abnormalities and disability, suggesting that multimodal evoked potentials could be useful in monitoring the disease evolution in single patients and as surrogate end points in clinical trials.

The purpose of the present study has been to give suggestions to guidelines for diagnosis and treatment of depression in MS in Denmark based on the international literature and recommendations. The method was a review of the relevant literature. The study recommends assessment of all MS patients for depression. Treatment of depression with serotonin reuptake inhibitors and/or cognitive behavioural therapy is recommended, depending on the severity of the illness. Caution is recommended in patients receiving beta interferon treatment.

    PubMed

    Ess, Kevin C

    2006-03-01

    Tuberous sclerosis complex (TSC) is a multiorgan genetic disease caused by inactivation of either the TSC1 or TSC2 genes. The disorder typically has profound neurologic involvement and often presents early in life with epilepsy, developmental delay, mental retardation, and autism. These features are generally accepted to result from structural brain abnormalities that are found in patients with TSC. Although much progress has recently been made in discerning the function(s) of the TSC genes, many questions remain as to the role of these genes in brain development and homeostasis. This review will summarize recent progress and suggest future avenues of basic science research.

    Pemphigus vulgaris (PV) is an autoimmune bullous and erosive mucocutaneous disease. Rarely, it occurs in patients with other autoimmune disease. The relation between PV and neurological disorders is unclear and needs to be more studied. Here, we report a case of amyotrophic lateral sclerosis (ALS), followed by dermatologic involvement. Histopathological evidence and direct immunofluorescence are consistent with PV. Systemic corticosteroid and azathioprine were effective in the treatment of mucocutaneous lesions. PV seems to be accidentally associated with ALS. Expression of major histocompatibility complex Class II in autoimmune disease and production of autoantibodies have been proposed to describe the association of PV with ALS. PMID:28163728

    Systemic sclerosis (SSc) is a complex autoimmune disease that occurs in a genetically susceptible host. Genetic studies performed so far reveal that multiple genetic loci contribute to disease susceptibility in SSc. The purpose of this review is to discuss the current knowledge of genetics in SSc by exploring the observational evidence, the different genetic studies, and their modalities as well as the most relevant genes discovered by these. The importance of gene expression variation and the different mechanisms that govern it, including the recently discovered field of epigenetics, are also explored, with an emphasis on microRNA.

    Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by small vessel vasculopathy, autoantibodies, and skin or visceral organ fibrosis (lung, oesophagus, kidney etc.) as a result of extracellular collagen deposition. The cancer risk is higher in many rheumatic diseases, including SSc. Various defined malignancies may develop in 3%-11% of patients with SSc. These solid tumors are generally observed in the lung, oesophagus, or breast. In addition, an increased risk for hematological cancers were reported in literature. Herein, we describe an interesting case of SSc complicated by myelodisplastic syndrome (MDS). Our aim is to draw attention to developing cancers and the rare occurence of MDS in patients with SSc.

    As part of an integrated geographical and environmental epidemiological study of multiple sclerosis (MS) in Budapest's Pesterzsébet district, many biometeorological variables were specifically examined. Also, the monthly distribution of birthdates of MS patients resident in the district was plotted. Patients reliably diagnosed with MS were found to have been born in greater numbers in the months of April and October, precisely 6 months apart. This finding indicates the presence of natural non-genetic factors in the creation of MS susceptibility, affecting the nervous system at the crucial time of myelination.

    Systemic sclerosis (SSc) is an acquired multiorgan connective tissue disease with variable mortality and morbidity dictated by clinical subset type. The etiology of the basic disease and pathogenesis of the systemic autoimmunity, fibrosis, and fibroproliferative vasculopathy are unknown and debated. In this review, the spectrum of vascular abnormalities and the options currently available to treat the vascular manifestations of SSc are discussed. Also discussed is how the hallmark pathologies (ie, how autoimmunity, vasculopathy, and fibrosis of the disease) might be effected and interconnected with modulatory input from lysophospholipids, sphingosine 1-phosphate, and lysophosphatidic acid.

    Disease-modifying treatments are now available in relapsing-remitting and secondary progressive multiple sclerosis (MS), and their beneficial effects have been shown in several clinical studies. However, as these treatments are only partially effective in halting the MS disease process and are frequently associated with side effects and suboptimal patient adherence, new oral therapeutic approaches are warranted. This review focuses on advances in current and novel oral treatment approaches for MS. Several pivotal reports have provided promising results for new oral therapies evaluating the safety and efficacy of new agents including fingolimod, fumaric acid, cladribine, teriflunomide and laquinimod.

    Several recent breakthroughs have provided notable insights into the pathogenesis of amyotrophic lateral sclerosis (ALS), with some even shifting our thinking about this neurodegenerative disease and raising the question as to whether this disorder is a proteinopathy, a ribonucleopathy or both. In addition, these breakthroughs have revealed mechanistic links between ALS and frontotemporal dementia, as well as between ALS and other neurodegenerative diseases, such as the cerebellar atrophies, myotonic dystrophy and inclusion body myositis. Here, we summarize the new findings in ALS research, discuss what they have taught us about this disease and examine issues that are still outstanding.

    Amyotrophic lateral sclerosis (ALS) exhibits characteristic variability of onset and rate of disease progression, with inherent clinical heterogeneity making disease quantitation difficult. Recent advances in understanding pathogenic mechanisms linked to the development of ALS impose an increasing need to develop strategies to predict and more objectively measure disease progression. This review explores phenotypic and genetic determinants of disease progression in ALS, and examines established and evolving biomarkers that may contribute to robust measurement in longitudinal clinical studies. With targeted neuroprotective strategies on the horizon, developing efficiencies in clinical trial design may facilitate timely entry of novel treatments into the clinic.

    2014-01-01

    Summary RuBPCase activase (RCA), an abundant photosynthetic protein is strongly down-regulated in response to Manduca sexta’s oral secretion (OS) in Nicotiana attenuata. RCA-silenced plants are impaired not only in photosynthetic capacity and growth, but also in jasmonic acid (JA)-isoleucine (Ile) signaling, and herbivore resistance mediated by JA-Ile dependent defense traits. These responses are consistent with a resource-based growth-defense trade-off. Since JA+Ile-supplementation of OS restored WT levels of JA-Ile, defenses and resistance to M. sexta, but OS supplemented individually with JA- or Ile did not, the JA-Ile deficiency of RCA-silenced plants could not be attributed to lower JA or Ile pools or JAR4/6 conjugating activity. Similar levels of JA-Ile derivatives after OS elicitation indicated unaltered JA-Ile turnover and lower levels of other JA-conjugates ruled out competition from other conjugation reactions. RCA-silenced plants accumulated more methyl jasmonate (MeJA) after OS elicitation, which corresponded with increased jasmonate methyltransferase (JMT) activity. RCA-silencing phenocopies JMT over-expression, wherein elevated JMT activity redirects OS-elicited JA flux towards inactive MeJA, creating a JA sink which depletes JA-Ile and its associated defense responses. Hence RCA plays an additional non-photosynthetic role in attenuating JA-mediated defenses and their associated costs potentially allowing plants to anticipate resource-based constraints on growth before they actually occur.

    About 3-5% of all patients with multiple sclerosis experience the onset of their disease under the age of 16. A significant proportion of paediatric multiple sclerosis patients develop significant cognitive disturbances and persistent physical disability. The high relapse rate and the morbidity in the paediatric multiple sclerosis population has triggered the use of disease-modifying therapies that have been shown to reduce relapse rate, disease progression and cognitive decline in adult patients with multiple sclerosis. Hard evidence for the right treatment and its appropriate timing is scarce in paediatric multiple sclerosis. Nevertheless, expertise in this field has grown thanks to recent open-label trials and experience generated in specialized centres. In spring 2009, a first meeting was held in Rotterdam with clinicians from 11 European countries (one from Canada) that are all active in the management of paediatric multiple sclerosis. One of the aims was to generate a common view on the management of paediatric multiple sclerosis patients. The result of this meeting is presented here to help standardize treatment and to support clinicians with less experience in this field.

    Patients with neurological disease of unknown etiology sometimes present with antigliadin and antitissue transglutaminase antibodies. The association between these antibodies and multiple sclerosis has been previously suggested. The purpose of this study was to determine the prevalence of these antibodies in multiple sclerosis patients. We determined the level of serum immunoglobulin A and immunoglobulin G antigliadin and antitissue transglutaminase antibodies in 98 patients with multiple sclerosis. We found a highly significant increase in titers of immunoglobulin G antibodies against gliadin and tissue transglutaminase in the multiple sclerosis patients. Seven patients had a positive IgG AGA, whereas only 2 controls presented positive titers (P = 0.03). Four patients had positive IgG anti-tTG while all the controls tested negative (P = 0.02). However, immunoglobulin A antibodies against gliadin and tissue transglutaminase were not statistically higher in the multiple sclerosis group in comparison to the control group. Our findings support the associations between antibodies against gliadin and tissue transglutaminase to multiple sclerosis. The specific role of these antibodies in the pathogenesis of multiple sclerosis remains uncertain and requires additional research. A gluten free diet should be considered in specific cases of patients who present with gluten antibodies.

    BACKGROUND Tuberous sclerosis complex is a multisystem genetic disorder with a range of physical manifestations that require evaluation, surveillance, and management. Individuals with tuberous sclerosis complex also have a range of behavioral, psychiatric, intellectual, academic, neuropsychologic, and psychosocial difficulties. These may represent the greatest burden of the disease. Around 90% of individuals with tuberous sclerosis complex will have some of these difficulties during their lifetime, yet only about 20% ever receive evaluation and treatment. The Neuropsychiatry Panel at the 2012 Tuberous Sclerosis Complex International Consensus Conference expressed concern about the significant “treatment gap” and about confusion regarding terminology relating to the biopsychosocial difficulties associated with tuberous sclerosis complex. METHODS The Tuberous Sclerosis Complex Neuropsychiatry Panel coined the term TAND—tuberous sclerosis complex-associated neuropsychiatric disorders—to bring together these multidimensional manifestations of the disorder, and recommended annual screening for TAND. In addition, the Panel agreed to develop a TAND Checklist as a guide for screening. RESULTS Here, we present an outline of the conceptualization of TAND, rationale for the structure of the TAND Checklist, and include the full US English version of the TAND Checklist. CONCLUSION We hope that the unified term TAND and the TAND Checklist will raise awareness of the importance of tuberous sclerosis complex-associated neuropsychiatric disorders and of the major burden of disease associated with it, provide a shared language and a simple tool to describe and evaluate the different levels of TAND, alert clinical teams and families or individuals of the importance of screening, assessment, and treatment of TAND, and provide a shared framework for future studies of tuberous sclerosis complex-associated neuropsychiatric disorders.

    The Amyotrophic lateral sclerosis (ALS) is the most common form of motor neuron disease in the adulthood, and it is characterized by rapid and progressive compromise of the upper and lower motor neurons. The majority of the cases of ALS are classified as sporadic and, until now, a specific cause for these cases still is unknown. To present the different hypotheses on the etiology of ALS. It was carried out a search in the databases: Bireme, Scielo and Pubmed, in the period of 1987 to 2011, using the following keywords: Amyotrophic lateral sclerosis, motor neuron disease, etiology, causes and epidemiology and its similar in Portuguese and Spanish. It did not have consensus as regards the etiology of ALS. Researches demonstrates evidences as regards intoxication by heavy metals, environmental and occupational causes, genetic mutations (superoxide dismutase 1), certain viral infections and the accomplishment of vigorous physical activity for the development of the disease. There is still no consensus regarding the involved factors in the etiology of ALS. In this way, new research about these etiologies are necessary, for a better approach of the patients, promoting preventive programs for the disease and improving the quality of life of the patients.

    Objective: To examine dermatoglyphic features to clarify implicated genetic predisposition in the etiology of multiple sclerosis (MS). Methods: The study was conducted between January and December 2013 in the Departments of Anatomy, and Neurology, Cumhuriyet University School of Medicine, Sivas, Turkey. The dermatoglyphic data of 61 patients, and a control group consisting of 62 healthy adults obtained with a digital scanner were transferred to a computer environment. The ImageJ program was used, and atd, dat, adt angles, a-b ridge count, sample types of all fingers, and ridge counts were calculated. Results: In both hands of the patients with MS, the a-b ridge count and ridge counts in all fingers increased, and the differences in these values were statistically significant. There was also a statistically significant increase in the dat angle in both hands of the MS patients. On the contrary, there was no statistically significant difference between the groups in terms of dermal ridge samples, and the most frequent sample in both groups was the ulnar loop. Conclusions: Aberrations in the distribution of dermatoglyphic samples support the genetic predisposition in MS etiology. Multiple sclerosis susceptible individuals may be determined by analyzing dermatoglyphic samples. PMID:25274586

    Aim of the database The Danish Multiple Sclerosis Treatment Register (DMSTR) serves as a clinical quality register, enabling the health authorities to monitor the quality of the disease-modifying treatment, and it is an important data source for epidemiological research. Study population The DMSTR includes all patients with multiple sclerosis who had been treated with disease-modifying drugs since 1996. At present, more than 8,400 patients have been registered in this database. Data are continuously entered online into a central database from all sites in Denmark at start and at regular visits. Main variables Include age, sex, onset year and year of the diagnosis, basic clinical information, and information about treatment, side effects, and relapses. Descriptive data Notification is done at treatment start, and thereafter at every scheduled clinical visit 3 months after treatment start, and thereafter every 6 months. The longitudinally collected information about the disease activity and side effects made it possible to investigate the clinical efficacy and adverse events of different disease-modifying therapies. Conclusion The database contributed to a certain harmonization of treatment procedures in Denmark and will continue to be a major factor in terms of quality in clinical praxis, research and monitoring of adverse events, and plays an important role in research.

    In a nationwide investigation the risk of death by suicide for patients with multiple sclerosis (MS) was assessed using records kept at the Danish Multiple Sclerosis Registry (DMSR) and the Danish National Register of Cause of Death. The investigation covers all MS patients registered with DSMR with an onset of the disease within the period 1953-85, or for whom MS was diagnosed in the same period. Fifty three of the 5525 cases in the onset cohort group committed suicide. Using the figures from the population death statistics by adjustment to number of subjects, duration of observation, sex, age, and calendar year at the start of observation, the expected number of suicides was calculated to be nearly 29. The cumulative lifetime risk of suicide from onset of MS, using an actuarial method of calculation, was 1.95%. The standard mortality ratio (SMR) of suicide in MS was 1.83. It was highest for males and for patients with onset of MS before the age of 30 years and those diagnosed before the age of 40. The SMR was highest within the first five years after diagnosis.

    Multiple sclerosis is a complex disease associated with a wide variety of different symptoms that can affect the ability of multiple sclerosis patients to carry out normal activities of daily living. Although a myriad of symptoms can afflict these patients, the most commonly reported include fatigue, mood disorders, changes in cognitive function or memory, sensory changes (numbness, pain, vibrations), motor changes (loss of balance, poor coordination, muscle weakness or stiffness), vision changes (double vision, blurred vision, loss of vision) and bladder or bowel dysfunction. Treatments are available that can help minimise some of these symptoms and relieve patient distress. After the diagnosis has been established and a decision taken regarding initiation of immunomodulatory treatments, the majority of management decisions with which the physician will be confronted will concern symptom management. Whereas some symptoms are relatively easily treated, others are more difficult to manage. Management involves rehabilitation, pharmacological treatments and surgical procedures. Successful symptom management is a key determinant of quality of life for the patient and is the basis for improving physical and psychological function.

    Multiple sclerosis plaques were immunohistochemically stained to exhibit cells expressing immune-system antigens. Human leukocyte antigen (HLA)-DR-positive cells formed dense rings around all plaque regions. The majority were reactive microglia/macrophages. Counterstaining with oil red O revealed heavy myelin debris within these cells. They were distinct from astrocytes, which were identified with an antibody to glial fibrillary acidic protein (GFAP) and which did not contain oil red O myelin debris. Numerous leukocytes and microglia were stained with antibody to leukocyte common antigen (LCA). Lymphocytes in cuffs around vessels, along the margins of capillary walls, and, sparingly, in the tissue matrix of affected areas, were stained with antibodies to CD4 (T-helper/inducer) and CD8 (T-cytotoxic/suppressor). In experimental allergic encephalomyelitis (EAE) induced in Lewis rats, a similar proliferation of Ia-positive (OX6, OX17) cells displaying reactive microglia/macrophage morphology was observed. These Ia-positive cells also were easily distinguished from GFAP-positive astrocytes. The results suggest that macrophages/reactive microglia, and not astrocytes, express class II MHC antigens in multiple sclerosis and EAE plaques.

    Collagen type IV is the primary collagen in the basement membranes around blood vessels and in the dermoepidermal junction in the skin. Perivascular collagen type IV is synthesized by endothelial cells and pericytes, and contributes to the homeostasis and remodeling of blood vessels. It has been well recognized that elevated serum collagen type IV levels are associated with the liver fibrosis. The objective was to examine serum collagen type IV levels and their clinical associations in patients with systemic sclerosis (SSc), and to examine the expression of collagen type IV in the fibrotic skin in SSc. Serum collagen type IV levels in SSc patients and diffuse cutaneous type SSc patients were significantly higher than those in healthy individuals. Serum collagen type IV levels were positively correlated with modified Rodnan total skin score. Serum collagen type IV levels in early stage (disease duration ≤3 years) diffuse cutaneous SSc patients were significantly elevated. Serum collagen type IV levels in SSc patients with digital ulcers (DU) were significantly elevated. In immunohistochemical staining, the expression of collagen type IV around dermal small vessels in the affected skin was reduced compared with those of normal individuals. These results suggest that elevated serum collagen type IV levels may be associated with the skin sclerosis in the early stage of SSc. The measurement of serum collagen type IV levels in SSc patients may be useful as a disease activity marker in skin sclerosis and DU.

    Jaw, blink and corneal reflexes, which all involve the trigeminal system, were recorded in 54 patients with multiple sclerosis; thirty-seven of these patients were classified as having definite multiple sclerosis and 17 as indefinite multiple sclerosis, according to Schumacher's criteria. The jaw reflex was abnormal less frequently than either of the other two reflexes, but in four cases it was the only abnormal reflex found. Testing a combination of two or three trigeminal reflexes did not yield a higher incidence of abnormalities than testing the blink or corneal reflex alone. Nine patients showed abnormal reflexes which were unexpected on the basis of clinical symptoms. The combined recordings demonstrate at least one abnormal reflex in 74% of the patients. The various types of reflex abnormalities reflect major damage to different parts of the trigeminal system and may therefore make an important contribution to the diagnosis of multiple sclerosis.

    Amyotrophic lateral sclerosis, the most common adult-onset motor neuron disease, leads to death within 3 to 5 years after onset. Beyond progressive motor impairment, patients with amyotrophic lateral sclerosis suffer from major defects in energy metabolism, such as weight loss, which are well correlated with survival. Indeed, nutritional intervention targeting weight loss might improve survival of patients. However, the neural mechanisms underlying metabolic impairment in patients with amyotrophic lateral sclerosis remain elusive, in particular due to the lack of longitudinal studies. Here we took advantage of samples collected during the clinical trial of pioglitazone (GERP-ALS), and characterized longitudinally energy metabolism of patients with amyotrophic lateral sclerosis in response to pioglitazone, a drug with well-characterized metabolic effects. As expected, pioglitazone decreased glycaemia, decreased liver enzymes and increased circulating adiponectin in patients with amyotrophic lateral sclerosis, showing its efficacy in the periphery. However, pioglitazone did not increase body weight of patients with amyotrophic lateral sclerosis independently of bulbar involvement. As pioglitazone increases body weight through a direct inhibition of the hypothalamic melanocortin system, we studied hypothalamic neurons producing proopiomelanocortin (POMC) and the endogenous melanocortin inhibitor agouti-related peptide (AGRP), in mice expressing amyotrophic lateral sclerosis-linked mutant SOD1(G86R). We observed lower Pomc but higher Agrp mRNA levels in the hypothalamus of presymptomatic SOD1(G86R) mice. Consistently, numbers of POMC-positive neurons were decreased, whereas AGRP fibre density was elevated in the hypothalamic arcuate nucleus of SOD1(G86R) mice. Consistent with a defect in the hypothalamic melanocortin system, food intake after short term fasting was increased in SOD1(G86R) mice. Importantly, these findings were replicated in two other amyotrophic

    A retrospective case-control study was conducted using 46 patients affected by amyotrophic lateral sclerosis and 92 closely matched healthy controls. Cases were ascertained through typical clinical and instrumental findings. Putative risk factors (bone fractures or major trauma, exposure to domestic animals, surgical operations, disease among first degree relatives and others) were investigated anamnestically using a standard questionnaire. Using Mantel-Haenzsel estimates of the odds ratio, no association was found between amyotrophic lateral sclerosis and the investigated variables.

    Abstract Constipation, obstructed defecation, and fecal incontinence are frequent complaints in multiple sclerosis. The literature on the pathophysiological mechanisms underlying these disorders is scant. Using anorectal manometry, we compared the anorectal function in patients with and without multiple sclerosis. 136 patients referred from our Center for Multiple Sclerosis to the Coloproctology Outpatient Clinic, between January 2005 and December 2011, were enrolled. The patients were divided into four groups: multiple sclerosis patients with constipation (group A); multiple sclerosis patients with fecal incontinence (group B); non-multiple sclerosis patients with constipation (group C); non-multiple sclerosis patients with fecal incontinence (group D). Anorectal manometry was performed to measure: resting anal pressure; maximum squeeze pressure; rectoanal inhibitory reflex; filling pressure and urge pressure. The difference between resting anal pressure before and after maximum squeeze maneuvers was defined as the change in resting anal pressure calculated for each patient. Results Group A patients were noted to have greater sphincter hypotonia at rest and during contraction compared with those in group C (p=0.02); the rectal sensitivity threshold was lower in group B than in group D patients (p=0.02). No voluntary postcontraction sphincter relaxation was observed in either group A or group B patients (p=0.891 and p=0.939, respectively). Conclusions The decrease in the difference in resting anal pressure before and after maximum squeeze maneuvers suggests post-contraction sphincter spasticity, indicating impaired pelvic floor coordination in multiple sclerosis patients. A knowledge of manometric alterations in such patients may be clinically relevant in the selection of patients for appropriate treatments and for planning targeted rehabilitation therapy.

    Tuberous sclerosis is not as rare as once thought and has high psychiatric comorbidities. However, bipolar or psychotic features associated with tuberous sclerosis have been rarely reported. This report first presents a tuberous sclerosis patient, resembling a schizoaffective disorder of bipolar type. A patient with known tuberous sclerosis displayed mood fluctuation and psychotic features. Her symptoms did not remit along with several psychiatric medications. After hospitalization, the patient responded well with lamotrigine and aripiprazole without exacerbation. As demonstrated in this case, tuberous sclerosis may also encompass bipolar affective or psychotic features. We would like to point out the necessity to consider bipolarity in evaluating and treating tuberous sclerosis. PMID:27489387

    Amyotrophic lateral sclerosis (ALS) represents the most common motoneuron disorder in adulthood. It is characterized by selective degeneration of the motoneurons. About 10% of patients have a genetically determined ALS. Clinically, ALS is characterized by coexistence of signs of the first motoneuron, such as spasticity and hyperreflexia, as well as the second motoneuron, such as muscular atrophy and fasciculations. If such signs are present in at least three regions and if other possible causes have been excluded, a definite diagnosis of ALS can be made based on the revised El-Escorial criteria. Initial manifestations are often focalized and generalization develops during the course. The glutamate antagonist riluzole is worldwide the only approved ALS treatment. However, symptomatic treatments to ameliorate spasticity, drooling, speech and swallowing problems, and assisted ventilation to treat respiratory failure are essential.

    Multiple sclerosis (MS) is a chronic progressive disease which is one of the leading causes of handicap in young subjects. The large range of symptoms associated with MS lead to continuing decline in neurologic status and quality of life. The coexistence of physical and cognitive impairments, together with the imprevisible evolution of the disease makes MS rehabilitation very challenging. The main objective of rehabilitation is, therefore, to ease the burden of symptoms by improving self-performance and independence. Inpatient, outpatient and Home rehabilitation with multidisciplinary team has been shown to be beneficial in improving disability. Individualized programs elaborated by a multidisciplinary team of experts are the key to success of rehabilitation. Family plays a big role and Family Based Rehabilitation will be important in long term rehab program in MS. PMID:26538848

    Multiple sclerosis is a chronic demyelinating disease of the central nervous system that occurs primarily in young adults. There is no single diagnostic test to recognize the disease. The diagnostic criteria, based on clinical examination and laboratory tests, have changed considerably over time. The first guidelines involved only the results of the patient's neurological examination. The diagnostic criteria developed by Poser in 1983 were based largely on the results of additional tests, including visual evoked potentials and analysis of cerebrospinal fluid. The McDonald criteria, developed in 2001 and updated in 2005 and 2010, reflected the diagnostic breakthrough caused by widespread use of magnetic resonance imaging (MRI). Currently, the diagnosis depends largely on the results of the MRI examination. An early diagnosis is particularly important for starting disease-modifying treatments.

  2. Low dose naltrexone therapy in multiple sclerosis.

    PubMed

    Agrawal, Y P

    2005-01-01

    The use of low doses of naltrexone for the treatment of multiple sclerosis (MS) enjoys a worldwide following amongst MS patients. There is overwhelming anecdotal evidence, that in low doses naltrexone not only prevents relapses in MS but also reduces the progression of the disease. It is proposed that naltrexone acts by reducing apoptosis of oligodendrocytes. It does this by reducing inducible nitric oxide synthase activity. This results in a decrease in the formation of peroxynitrites, which in turn prevent the inhibition of the glutamate transporters. Thus, the excitatory neurotoxicity of glutamate on neuronal cells and oligodendrocytes via activation of the alpha-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid class of glutamate receptor is prevented. It is crucial that the medical community respond to patient needs and investigate this drug in a clinical trial.

    Multiple sclerosis (MS) is a chronic demyelinating neurological disorder affecting people worldwide; women are affected more than men. MS results in serious neurological deficits along with behavioral compromise, the mechanisms of which still remain unclear. Behavioral disturbances such as depression, anxiety, cognitive impairment, psychosis, euphoria, sleep disturbances, and fatigue affect the quality of life in MS patients. Among these, depression and psychosis are more common than any other neurological disorders. In addition, depression is associated with other comorbidities. Although anxiety is often misdiagnosed in MS patients, it can induce suicidal ideation if it coexists with depression. An interrelation between sleep abnormalities and fatigue is also reported among MS patients. In addition, therapeutics for MS is always a challenge because of the presence of the blood–brain barrier, adding to the lack of detailed understanding of the disease pathology. In this review, we tried to summarize various behavioral pathologies and their association with MS, followed by its conventional treatment and nanotheranostics. PMID:26508863

    Regional in vivo proton magnetic resonance spectroscopy provides quantitative data on selected chemical constituents of brain. We imaged 16 volunteers with clinically definite multiple sclerosis on a 1.5 tesla magnetic resonance scanner to define plaque-containing volumes of interest, and obtained localized water-suppressed proton spectra using a stimulated echo sequence. Twenty-five of 40 plaque-containing regions provided spectra of adequate quality. Of these, 8 spectra from 6 subjects were consistent with the presence of cholesterol or fatty acids; the remainder were similar to those obtained from white matter of normal volunteers. This early experience with regional proton spectroscopy suggests that individual plaques are distinct. These differences likely reflect dynamic stages of the evolution of the demyelinative process not previously accessible to in vivo investigation.

    Amyotrophic lateral sclerosis (ALS) is the most common, progressive motor neurone disease but is rare in the obstetric population. Only 4 cases have been described in the English literature since 1975. We describe a 29 year old woman who presented with ataxia, lower limb weakness and dysarthria 4 weeks after the birth of her first child. The symptoms had onset during the pregnancy but had not been considered remarkable. There were clinical features of upper and lower motor neurone involvement without any sensory loss. MRI of brain and spine was normal. CSF analysis was negative. EMG studies confirmed the presence of widespread anterior horn cell dysfunction compatible with ALS. The patient was commenced on Riluzole and has progressed clinically, at 12 months post diagnosis.

    Summary Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder that affects central and peripheral motor neuron cells. Its etiology is unknown, although a relationship between genetic background and environmental factors may play a major role in triggering the neurodegeneration. In this review, we analyze the role of environmental factors in ALS: heavy metals, electromagnetic fields and electric shocks, pesticides, β-N-methylamino-L-alanine, physical activity and the controversial role of sports. The literature on the single issues is analyzed in an attempt to clarify, as clearly as possible, whether each risk factor significantly contributes to the disease pathogenesis. After summarizing conflicting observations and data, the authors provide a final synthetic statement. PMID:27027889

    Exercise training represents a behavioral approach for safely managing many of the functional, symptomatic, and quality of life consequences of multiple sclerosis (MS). This topical review paper summarizes evidence from literature reviews and meta-analyses, supplemented by recent individual studies, indicating that exercise training can yield small but important improvements in walking, balance, cognition, fatigue, depression, and quality of life in MS. The paper highlights limitations of research on exercise training and its consequences and future research directions and provides an overview for promotion of exercise training in MS based on recent prescriptive guidelines. Collectively, the evidence for the benefits of exercise training in MS suggests that the time is ripe for the promotion of exercise by healthcare providers, particularly neurologists as a central part of the clinical care and management of MS patients.

    An estimated 2 % to 5 % of all persons with multiple sclerosis (MS) have onset of symptoms before 16 years of age Krupp and Hertz (Neurology 68(Suppl 2), 2007). As in adults, the diagnosis of pediatric MS is a clinical one, requiring recurrent episodes of CNS demyelination with supportive paraclinical data (MRI findings, CSF characteristics) in the absence of another plausible diagnosis. The differential diagnosis is broad and, the more atypical the case and the younger the child, the more consideration is necessary before making a diagnosis of MS. MS must be differentiated from acute disseminated encephalomyelitis (ADEM) or neuromyelitis optica (NMO). After initial presentation with a CNS demyelinating event or clinically isolated syndrome (CIS), children can meet the diagnostic criteria for MS if serial changes are noted on MRI and other disorders are excluded. Accurate diagnosis of pediatric MS is critical because of the implications of the diagnosis, including the need for long-term disease modifying therapy.

    PubMed

    Oksenberg, J R; Barcellos, L F

    2005-08-01

    Compelling epidemiologic and molecular data indicate that genes play a primary role in determining who is at risk for developing multiple sclerosis (MS), how the disease progresses, and how someone responds to therapy. The genetic component of MS etiology is believed to result from the action of allelic variants in several genes. Their incomplete penetrance and moderate individual effect probably reflects epistatic interactions, post-transcriptional regulatory mechanisms, and significant environmental influences. Equally significant, it is also likely that locus heterogeneity exists, whereby specific genes influence susceptibility and pathogenesis in some individuals but not in others. With the aid of novel analytical algorithms, the combined study of genomic, transcriptional, proteomic, and phenotypic information in well-controlled study groups will define a useful conceptual model of pathogenesis and a framework for understanding the mechanisms of action of existing therapies for this disorder, as well as the rationale for novel curative strategies.

    Multiple sclerosis (MS) is being increasingly diagnosed in India mainly due to increase in the number of practicing neurologists and easy and affordable availability of magnetic resonance imaging (MRI). The clinical features and course are largely similar to those seen in the West. The term optico-spinal MS (Asian MS) was coined in the pre-MRI days. Many such patients turn out to be cases of neuromyelitis optica — a distinct disorder and not a variant of MS. Others have shown the classical features of MS on MRI scan. Several of the disease-modifying agents, not all, are now available in India. Their use, however, has been limited in view of the high cost. PMID:26538844

    Monoclonal antibodies (mAbs) are used as therapeutics in a number of disciplines in medicine, such as oncology, rheumatology, gastroenterology, dermatology and transplant rejection prevention. Since the introduction and reintroduction of the anti-alpha4-integrin mAb natalizumab in 2004 and 2006, mAbs have gained relevance in the treatment of multiple sclerosis (MS). At present, numerous mAbs have been tested in clinical trials in relapsing–remitting MS, and in progressive forms of MS. One of the agents that might soon be approved for very active forms of relapsing–remitting MS is alemtuzumab, a humanized mAb against CD52. This review provides insights into clinical studies with the mAbs natalizumab, alemtuzumab, daclizumab, rituximab, ocrelizumab and ofatumumab. PMID:24001305

    Multiple sclerosis (MS) is a relatively common and etiologically unknown disease with no cure treatment. It is the leading cause of neurological disability in young adults, affecting over two million people worldwide. Traditionally, MS has been considered a chronic, inflammatory disorder of the central white matter in which ensuing demyelination results in physical disability. Recently, MS has become increasingly viewed as a neurodegenerative disorder in which axonal injury, neuronal loss, and atrophy of the central nervous system lead to permanent neurological and clinical disability. In this article, we discuss the latest developments on MS research, including etiology, pathology, genetic association, EAE animal models, mechanisms of neuronal injury and axonal transport and therapeutics. In this article, we also focus on the mechanisms of mitochondrial dysfunction that are involved in MS, including mitochondrial DNA defects, and mitochondrial structural/functional changes.

    Optical or electronic vision aids enabled 35 of 39 visually handicapped multiple sclerosis patients to read. Six patients had an uncorrected ametropia. 15 could read again with the help of magnifying optical aids and 11 with the help of an electronic television system. An electronic television reader was useful when visual acuities were below 0.1 and in patients with oscillating nystagmus or tremor capitis. Contact lenses helped 3 patients who had a neurogenous visual defect and oscillating nystagmus. Although acquired oscillating nystagmus disappears on eyelid closure and only reappears again on fixation, its amplitude, when unable to read, is greater. On overcoming the neurogenous visual defect with vision aids it becomes smaller.

Because many patients have numerous concurrent symptoms during their clinical course, their management is complex and consequently it is important to know which symptoms are a direct result of the degenerative lesions of MS. The present article describes all the therapeutic options available for spasticity and its associated pain, paroxystic symptoms, fatigue, genitourinary disorders and sexual dysfunction, tremor, ataxia, gait disorder and cognitive impairment, with special emphasis on novel treatments. The article also defines exacerbations, how to recognize them and the available treatments, mainly oral administration of high-dose methylprednisolone and plasmapheresis.

    Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by small vessel vasculopathy, autoantibodies, and skin or visceral organ fibrosis (lung, oesophagus, kidney etc.) as a result of extracellular collagen deposition. The cancer risk is higher in many rheumatic diseases, including SSc. Various defined malignancies may develop in 3%–11% of patients with SSc. These solid tumors are generally observed in the lung, oesophagus, or breast. In addition, an increased risk for hematological cancers were reported in literature. Herein, we describe an interesting case of SSc complicated by myelodisplastic syndrome (MDS). Our aim is to draw attention to developing cancers and the rare occurence of MDS in patients with SSc.

    Dysarthria is a motor disorder of speech characterized by abnormalities of the articulation and intelligibility of speech. Phonation and the rate of facial movements may also be affected. Understanding the nature and course of dysarthria in amyotrophic lateral sclerosis (ALS) is important because loss of communication prevents patients from participating in many activities, may lead to social isolation, and reduces the quality of life. The goal of management of dysarthria in ALS patients is to optimize communication effectiveness for as long as possible. The information about dysarthria in ALS is dispersed in physiological, pathological, speech therapy, otorhinolaringological and neurological publications. This review summarizes the current state of knowledge on the clinical features, differential diagnosis, pathophysiology, investigations and management of dysarthria in ALS patients. There is a need to compare the different methods used to assess dysarthria and for controlled clinical trials to assess therapeutic strategies.

    Amyotrophic lateral sclerosis (ALS) is a late-onset fatal neurodegenerative disease affecting motor neurons with an incidence of about 1/100,000. Most ALS cases are sporadic, but 5–10% of the cases are familial ALS. Both sporadic and familial ALS (FALS) are associated with degeneration of cortical and spinal motor neurons. The etiology of ALS remains unknown. However, mutations of superoxide dismutase 1 have been known as the most common cause of FALS. In this study, we provide a comprehensive review of ALS. We cover all aspects of the disease including epidemiology, comorbidities, environmental risk factor, molecular mechanism, genetic factors, symptoms, diagnostic, treatment, and even the available supplement and management of ALS. This will provide the reader with an advantage of receiving a broad range of information about the disease. PMID:26629397

    The authors studied gastric emptying (GE) in patients with peripheral manifestations of progressive systemic sclerosis (PSS) using a radionuclide method. 18 patients underwent esophageal manometry and a GE study using chicken liver labeled in vivo with Tc-99m sulfur colloid as a marker of solid emptying. GE was also measured in 13 normal volunteers. 4 PSS patients with normal esophageal motility also had normal GE. The GE of 14 PSS patients with abnormal esophageal motility was significantly (p < 0.05) delayed; with 67.4% retention of isotope after 2 hours compared to 49.8 in normals. The authors conclude that GE of solids is slow in approximately 2/3 of PSS patients with abnormal esophageal motility but is normal if the esophagus is uninvolved; Delayed GE may contribute to the severity of gastroesophageal reflux in PSS patients and the degree of dysphasgia; and Metoclopramide accelerates GE in PSS patients and should have a valuable therapeutic role.

    Previous studies have suggested that mitochondrial metabolism and/or mitochondrial DNA (mtDNA) could be, in conjunction with other genetic or environmental factors, a risk factor for the development of multiple sclerosis (MS). One of these studies establishes that mitochondrial haplogroup JT is a risk factor for developing the disease, in particular the visual manifestations [optic neuritis (ON)]. Nevertheless, as distribution of these haplogroups varies between populations, the observed association may be due to a slanted sample with no physiopathological value. This hypothesis was checked with MS patients, originals from Basque country (this population has peculiar genetic characteristics) and from other Spanish regions. We concluded that such an association does not exist. By contrast, a decrease could be seen in the frequency of the JT haplogroup in the ON group and in the MS-Basque group. That trend could be a protective effect, which needs to be verified in further investigations.

    The recent years have witnessed great efforts in establishing new therapeutic options for multiple sclerosis (MS), especially for relapsing–remitting disease courses. In particular, the application of monoclonal antibodies provide innovative approaches allowing for blocking or depleting specific molecular targets, which are of interest in the pathogenesis of MS. While natalizumab received approval by the US Food and Drug Administration and the European Medicines Agency in 2006 as the first monoclonal antibody in MS therapy, rituximab, alemtuzumab, and daclizumab were successfully tested for relapsing-remitting MS in small cohorts in the meantime. Here, we review the data available from these recent phase II trials and at the same time critically discuss possible pitfalls which may be relevant for clinical practice. The results of these studies may not only broaden our therapeutic options in the near future, but also provide new insights into disease pathogenesis. PMID:21180564

    Natalizumab reduced the rate of clinical relapse at one year by 68% and the risk of sustained progression of disability by 42-54% over 2 years in its pivotal phase III trial (AFFIRM) in relapsing-remitting multiple sclerosis (RRMS). Natalizumab is generally well tolerated, but due to rare and potentially fatal side-effects, it was approved with a restricted-distribution format in 2006. Expert statements and the European Medical Agency recommend the use of natalizumab after failure of first-line disease-modifying therapies in patients with relapsing forms of MS. As part of the risk management plan, worldwide extensive safety programmes aim to provide more data on natalizumab safety in clinical practice. At the end of September 2008, 48 000 patients have received natalizumab and 18000 patients are on treatment for at least 1 year. The assessment of risk and benefit is still ongoing. PMID:21180646

    OBJECTIVES--To determine whether oligoclonal band (OCB) negative multiple sclerosis is a reliable diagnosis and, if so, whether it has a distinctive prognosis. METHODS--Retrospective and matched prospective comparison of the clinical and laboratory features of patients with clinical definite multiple sclerosis with and without intrathecal synthesis of oligoclonal IgG. RESULTS--Thirty four patients were identified with apparent OCB negative clinically definite multiple sclerosis. The results of oligoclonal banding proved to have been equivocal in 14 of 34; the clinical diagnosis of multiple sclerosis was questionable in 8 of 34. The remaining 12 patients with "true" OCB negative multiple sclerosis were significantly less disabled than matched OCB positive controls. Re-examination of CSF-serum pairs from six OCB negative patients showed that three remained OCB negative while three showed evidence of intrathecal synthesis of OCBs. CONCLUSIONS--OCB negative clinically definite multiple sclerosis is rare and should be diagnosed with caution; in unequivocal cases it seems to have a relatively benign prognosis. PMID:8558146

    2017-03-01

    Recent times have seen an increase in the number of options to treat multiple sclerosis. Ocular manifestations of multiple sclerosis are well known to treating physicians; however, the medications used to treat multiple sclerosis can also have ocular side effects. This review article focuses on the ocular manifestations of corticosteroids and disease-modifying agents such as interferon, fingolomod, natalizumab, alemtuzumab and mitoxantron used to treat the disease. The ocular manifestations of multiple sclerosis treatments can be varied depending on the drug used, and include retinopathy, chronic central serous chorioretinopathy, macular oedema, Graves' ophthalmopathy and cortical blindness. These effects may be specific to the drug or secondary to their immunosuppressive effect. The association of macular oedema with fingolomod is clear and merits ocular screening for toxicity. The immunosuppressive nature of the treatments makes patients prone to acquired infections. Hence, if a patient with multiple sclerosis presents with vision loss, infectious and drug-induced aetiology should be considered alongside relapses of multiple sclerosis itself as a cause.

    Objective: To assess the therapy-related risk of malignancies in mitoxantrone-treated patients with multiple sclerosis. Methods: This retrospective observational cohort study included all mitoxantrone-treated patients with multiple sclerosis seen at our department between 1994 and 2007. We collected follow-up information on medically confirmed malignancies, life status, and cause of death, as of 2010. Malignancy rates were compared to the German national cancer registry matched for sex, age, and year of occurrence. Results: Follow-up was completed in 676 of 677 identified patients. Median follow-up time was 8.7 years (interquartile range 6.8–11.2), corresponding to 6,220 person-years. Median cumulative mitoxantrone dose was 79.0 mg/m2 (interquartile range 50.8–102.4). Thirty-seven patients (5.5%) were diagnosed with a malignancy after mitoxantrone initiation, revealing a standardized incidence ratio of 1.50 (95% confidence interval [CI] 1.05–2.08). Entities included breast cancer (n = 9), colorectal cancer (n = 7), acute myeloid leukemia (n = 4, 0.6%), and others (each entity n = 1 or 2). The standardized incidence ratio of colorectal cancer was 2.98 (95% CI 1.20–6.14) and of acute myeloid leukemia 10.44 (95% CI 3.39–24.36). It was not increased for other entities including breast cancer. Multivariate Cox regression identified higher age at treatment initiation but neither cumulative mitoxantrone dose (>75 vs ≤75 mg/m2) nor treatment with other immunosuppressive drugs or sex as a risk factor. Fifty-five patients had died, among them 12 of a malignancy and 43 reportedly of other causes. Conclusions: While the overall incidence of malignancies was only mildly increased, the risk of leukemia and colorectal cancer was heightened. If confirmed, posttherapy colonoscopy could become advisable. PMID:27170571

    Study Objectives: To examine associations between cognitive performance and polysomnographic measures of obstructive sleep apnea in patients with multiple sclerosis (MS). Methods: Participants underwent a comprehensive MS-specific cognitive testing battery (the Minimal Assessment of Cognitive Function in MS, or MACFIMS) and in-laboratory overnight PSG. Results: In adjusted linear regression models, the oxygen desaturation index (ODI) and minimum oxygen saturation (MinO2) were significantly associated with performance on multiple MACFIMS measures, including the Paced Auditory Serial Addition Test (PASAT; 2-sec and 3-sec versions), which assesses working memory, processing speed, and attention, and on the Brief Visuospatial Memory Test-Revised, a test of delayed visual memory. The respiratory disturbance index (RDI) was also significantly associated with PASAT-3 scores as well as the California Verbal Learning Test-II (CVLT-II) Discriminability Index, a test of verbal memory and response inhibition. Among these associations, apnea severity measures accounted for between 12% and 23% of the variance in cognitive test performance. Polysomnographic measures of sleep fragmentation (as reflected by the total arousal index) and total sleep time also showed significant associations with a component of the CVLT-II that assesses response inhibition, explaining 18% and 27% of the variance in performance. Conclusions: Among patients with MS, obstructive sleep apnea and sleep disturbance are significantly associated with diminished visual memory, verbal memory, executive function (as reflected by response inhibition), attention, processing speed, and working memory. If sleep disorders degrade these cognitive functions, effective treatment could offer new opportunities to improve cognitive functioning in patients with MS.

    Although chemical immunosuppression has been shown to benefit patients with chronic progressive multiple sclerosis (MS), it appears that chemotherapy has an appreciable oncogenic potential in patients with multiple sclerosis. Accordingly, we developed a modified total lymphoid irradiation (TLI) regimen designed to reduce toxicity and applied it to a randomized double blind trial of TLI or sham irradiation in MS. Standard TLI regimens were modified to reduce dose to 1,980 rad, lowering the superior mantle margin to midway between the thyroid cartilage and angle of the mandible (to avert xerostomia) and the lower margin of the mantle field to the inferior margin of L1 (to reduce gastrointestinal toxicity by dividing abdominal radiation between mantle and inverted Y), limiting spinal cord dose to 1,000 rad by custom-made spine blocks in the mantle and upper 2 cm of inverted Y fields, and also protecting the left kidney even if part of the spleen were shielded. Clinical efficacy was documented by the less frequent functional scale deterioration of 20 TLI treated patients with chronic progressive MS compared to to 20 sham-irradiated progressive MS patients after 12 months (16% versus 55%, p less than 0.03), 18 months (28% versus 63%, p less than 0.03), and 24 months (44% versus 74%, N.S.). Therapeutic benefit during 3 years follow-up was related to the reduction in lymphocyte count 3 months post-irradiation (p less than 0.02). Toxicity was generally mild and transient, with no instance of xerostomia, pericarditis, herpes zoster, or need to terminate treatment in TLI patients. However, menopause was induced in 2 patients and staphylococcal pneumonia in one.

    Tuberous sclerosis complex (TSC) is known to cause severe intractable epilepsy and mental retardation; however, diagnosis can be delayed in milder cases. We report a 26-year-old right-handed female patient who started having convulsions at age 7 days. She had several focal seizures per year that were intractable to treatment with carbamazepine or phenytoin. Her two sisters had several episodes of suspected epileptic seizures but had no symptoms related to TSC. Seizure semiology of the patient comprised of visual hallucination, loss of consciousness, and convulsive movements predominantly on the right. Physical examination revealed several small scattered angiofibromas over the nose that were histologically determined by skin biopsy. Hypomelanotic macules, shagreen patches, or periungual fibromas were not seen. Neurological examination showed mental retardation (MMSE: 23/30, WAIS-III: VIQ63, PIQ59, FIQ58) and decreased vibration sensation in both legs. Interictal EEG showed slow waves and epileptiform discharges broadly over the anterior quadrants bilaterally. Brain imaging showed multiple cortical tubers and malformation of cortical development but no subependymal nodules. Interictal IMP-SPECT showed hypoperfusion in the left frontal lobe. Cardiac rhabdomyoma was not noticed by cardiac echography. Truncal CT showed sclerosis of the bilateral lumbosacral joints. There was no abnormality in the lung, major arteries, liver, or kidneys. No hamartomas or retinal achromic patches were noticed by ophthalmologic evaluation. Administration of lamotrigine was effective for her seizures. This patient fulfilled two major features of diagnostic criteria for TSC and was diagnosed as definite TSC. Patients with mental retardation and epilepsy should be carefully evaluated for the possible diagnosis of TSC.

    Background: Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease of the central nervous system of potential autoimmune origin that is frequently associated with psychological disorders and cognitive deficits, as well as with fatigue, stress, and psychosocial burden. These factors often cause decreased quality of life, social withdrawal, and unemployment. We describe the development of a cognitive-behavioral group intervention based on the concept of metacognition and evaluation of the feasibility and acceptance of the program as a rehabilitation tool. Methods: Metacognitive Training in MS (MaTiMS) consists of six modules, each 90 minutes in duration. We tested acceptance and design of the program in six focus groups (entire sample, n = 27). Framework analysis of transcripts was used to identify key topics and categories. Program modules were revised in accordance with appropriate recommendations of focus group members. We subsequently evaluated MaTiMS in two groups (n = 5, n = 6) in a rehabilitation center. Neuropsychological functioning as well as coping self-efficacy, depression, stress, perceived cognitive deficit, fatigue, and quality of life were assessed. Acceptance of MaTiMS from the patient perspective was also studied. Results: The modules were highly accepted by patients. Pre-post assessments showed significant improvements in the Coping Self Efficacy Scale (P = .007), the Würzburger Fatigue Inventory for MS Score (P = .028), and the Hamburg Quality of Life Questionnaire in Multiple Sclerosis Mood subscale (P = .046). Conclusions: These preliminary results suggest that MaTiMS represents a feasible psychological group training program that may foster improvements in self-efficacy, fatigue, and mood. The next step will be an evaluation of the program in a randomized controlled trial. PMID:26052258

    Background. Spasticity of the legs is common in multiple sclerosis (MS), but there has been limited research examining its association with ambulatory outcomes. Objective. This study examined spasticity of the legs and its association with multiple measures of ambulation in persons with MS. Methods. The sample included 84 patients with MS. Spasticity of the legs was measured using a 5-point rating scale ranging between 0 (normal) and 4 (contracted). Patients completed the 6-minute walk (6 MW), timed 25 foot walk (T25FW), and timed up-and-go (TUG), and O2 cost of walking was measured during the 6 MW. The patients undertook two walking trials on a GAITRite (CIR systems, Inc.) for measuring spatial and temporal parameters of gait. The patients completed the Multiple Sclerosis Walking Scale-12 (MSWS-12) and wore an accelerometer over a seven-day period. Results. 52% (n = 44) of the sample presented with spasticity of the legs. Those with leg spasticity had significantly worse ambulation as measured by 6 MW (P = 0.0001, d = -0.86), T25FW (P = 0.003, d = 0.72), TUG (P = 0.001, d = 0.84), MSWS-12 (P = 0.0001, d = 1.09), O2 cost of walking (P = 0.001, d = 0.75), average steps/day (P < 0.05, d = -0.45), and walking velocity (P < 0.05, d = -0.53) and cadence (P < 0.05, d = -0.46). Conclusion. Leg spasticity was associated with impairments in ambulation, including alterations in spatiotemporal parameters and free-living walking.

The observatory hosts a 41 cm automated telescope inside a 4 m dome located at the university main campus, in the outskirts of the city of Jaén (Spain). This facility is used for educational, outreach and occasional scientific research on bright stellar objects. Despite the observatory location in a light polluted urban area, its performance for differential photometry studies has proven to be very acceptable. The discovery of the Be star LS I +5979 as a peculiar eclipsing binary system is so far the most relevant achievement.

    2017-03-01

    During the past decades, better understanding of relapsing-remitting multiple sclerosis disease mechanisms have led to the development of several disease-modifying therapies, reducing relapse rates and severity, through immune system modulation or suppression. In contrast, current therapeutic options for progressive multiple sclerosis remain comparatively disappointing and challenging. One possible explanation is a lack of understanding of pathogenic mechanisms driving progressive multiple sclerosis. Furthermore, diagnosis is usually retrospective, based on history of gradual neurological worsening with or without occasional relapses, minor remissions or plateaus. In addition, imaging methods as well as biomarkers are not well established. Magnetic resonance imaging studies in progressive multiple sclerosis show decreased blood-brain barrier permeability, probably reflecting compartmentalization of inflammation behind a relatively intact blood-brain barrier. Interestingly, a spectrum of inflammatory cell types infiltrates the leptomeninges during subpial cortical demyelination. Indeed, recent magnetic resonance imaging studies show leptomeningeal contrast enhancement in subjects with progressive multiple sclerosis, possibly representing an in vivo marker of inflammation associated to subpial demyelination. Treatments for progressive disease depend on underlying mechanisms causing central nervous system damage. Immunity sheltered behind an intact blood-brain barrier, energy failure, and membrane channel dysfunction may be key processes in progressive disease. Interfering with these mechanisms may provide neuroprotection and prevent disability progression, while potentially restoring activity and conduction along damaged axons by repairing myelin. Although most previous clinical trials in progressive multiple sclerosis have yielded disappointing results, important lessons have been learnt, improving the design of novel ones. This review discusses mechanisms involved

    Three years after the introduction of natalizumab (NA) therapy for the second line treatment of relapsing-remitting multiple sclerosis (MS), Italian MS centers critically reviewed the scientific literature and their own clinical experience. Natalizumab was shown to be highly efficacious in the treatment of MS. However, the risk of progressive multifocal leukoencephalopathy was confirmed and defined better. This article summarizes the MS-SIN Study Group recommendations on the use of NA in MS, with particular reference to the appropriate selection and monitoring of patients as well as to the management of adverse events.

    Currently, lung impairment is the leading factor responsible for the morbidity and mortality associated with systemic sclerosis. Therefore, the recognition of the various tomography patterns becomes decisive in the clinical management of these patients. In high-resolution computed tomography studies, the most common pattern is that of nonspecific interstitial pneumonia. However, there are other forms of lung involvement that must also be recognized. The aim of this study was to review the literature on the main changes resulting from pulmonary involvement in systemic sclerosis and the corresponding radiological findings, considering the current classification of interstitial diseases. We searched the Medline (PubMed), Lilacs, and SciELO databases in order to select articles related to pulmonary changes in systemic sclerosis and published in English between 2000 and 2015. The pulmonary changes seen on computed tomography in systemic sclerosis are varied and are divided into three main categories: interstitial, alveolar, and vascular. Interstitial changes constitute the most common type of pulmonary involvement in systemic sclerosis. However, alveolar and vascular manifestations must also be recognized and considered in the presence of atypical clinical presentations and inadequate treatment responses. PMID:27818546

    Visual impairment is a key manifestation of multiple sclerosis. Acute optic neuritis is a common, often presenting manifestation, but visual deficits and structural loss of retinal axonal and neuronal integrity can occur even without a history of optic neuritis. Interest in vision in multiple sclerosis is growing, partially in response to the development of sensitive visual function tests, structural markers such as optical coherence tomography and magnetic resonance imaging, and quality of life measures that give clinical meaning to the structure-function correlations that are unique to the afferent visual pathway. Abnormal eye movements also are common in multiple sclerosis, but quantitative assessment methods that can be applied in practice and clinical trials are not readily available. We summarize here a comprehensive literature search and the discussion at a recent international meeting of investigators involved in the development and study of visual outcomes in multiple sclerosis, which had, as its overriding goals, to review the state of the field and identify areas for future research. We review data and principles to help us understand the importance of vision as a model for outcomes assessment in clinical practice and therapeutic trials in multiple sclerosis.

  4. Inflammatory Optic Neuritis: From Multiple Sclerosis to Neuromyelitis Optica.

    Inflammatory optic neuritis represents a frequent clinical situation in neurology and ophthalmology. In those parts of the world where multiple sclerosis is common, it is the condition most discussed as the cause of optic neuritis. However, the risk for conversion from optic neuritis to multiple sclerosis is evaluated at only around 50% after 15 years of follow-up. The risk is higher in cases in whom abnormalities typical of multiple sclerosis are found on magnetic resonance imaging of the brain and oligoclonal bands found on cerebrospinal fluid protein electrophoresis with no corresponding bands in serum. When these investigations are normal, optic neuritis is usually considered as "idiopathic" with a suspected viral aetiology, but in some cases, a systemic disease such as sarcoidosis, systemic lupus erythematosis, or Sjögren syndrome may be diagnosed. In rare cases, either recurrent optic neuritis or myelitis may occur without any evidence for multiple sclerosis. In the first case, it corresponds to a recently characterised disorder referred to as chronic relapsing inflammatory optic neuropathy and in the second case to a recently better identified entity, neuromyelitis optica. In the present paper, the differential diagnosis of inflammatory optic neuritis is presented from multiple sclerosis to infectious optic neuritis, systemic disease, and neuromyelitis optica.

  5. How can proteomics elucidate the complexity of multiple sclerosis?

    Multiple sclerosis affects more than 2.5 million people worldwide. Although multiple sclerosis was described almost 150 years ago, there are many knowledge gaps regarding its etiology, diagnosis, prognosis, and pathogenesis. Multiple sclerosis is an inflammatory, demyelinating, neurodegenerative disease of the CNS. During the last several decades, experimental models of multiple sclerosis have contributed to our understanding of the inflammatory disease mechanisms and have aided drug testing and development. However, little is known about the neurodegenerative mechanisms that operate during the evolution of the disease. Currently, all therapeutic approaches are primarily based on the inflammatory aspect of the disease. During the last decade, proteomics has emerged as a promising tool for revealing molecular pathways as well as identifying and quantifying differentially expressed proteins. Therefore, proteomics may be used for the discovery of biomarkers, potential drug targets, and new regulatory mechanisms. To date, a considerable number of proteomics studies have been conducted on samples from experimental models and patients with multiple sclerosis. These data form a solid base for further careful analysis and validation.

  6. Symptomatic cranial neuralgias in multiple sclerosis: clinical features and treatment.

    PubMed

    De Santi, Lorenzo; Annunziata, Pasquale

    2012-02-01

    In multiple sclerosis, neuropathic pain is a frequent condition, negatively influencing the overall quality of life. Cranial neuralgias, including trigeminal, glossopharyngeal neuralgias, as well as occipital neuralgia, are typical expression of neuropathic pain. Neuralgias are characterised by paroxysmal painful attacks of electric shock-like sensation, occurring spontaneously or evoked by innocuous stimuli in specific trigger areas. In multiple sclerosis, demyelination in the centrally myelinated part of the cranial nerve roots plays an important role in the origin of neuralgic pain. These painful syndromes arising in multiple sclerosis are therefore considered "symptomatic", in contrast to classic cranial neuralgias, in which no cause other than a neurovascular contact is identified. At this time, the evidence on the management of symptomatic cranial neuralgias in multiple sclerosis is fragmentary and a comprehensive review addressing this topic is still lacking. For that reason, treatment is often based on personal clinical experience as well as on anecdotal reports. The aim of this review is to critically summarise the latest findings regarding the pathogenesis, the diagnosis, the instrumental evaluation and the medical as well as neurosurgical treatment of symptomatic trigeminal, glossopharyngeal and occipital neuralgia in multiple sclerosis, providing useful insights for neurologists and neurosurgeons and a broad range of specialists potentially involved in the treatment of these painful syndromes.

    Multiple sclerosis patients who become pregnant experience a significant decrease in relapses that may be mediated by a shift in immune responses from T helper 1 to T helper 2. Animal models of multiple sclerosis have shown that the pregnancy hormone, estriol, can ameliorate disease and can cause an immune shift. We treated nonpregnant female multiple sclerosis patients with the pregnancy hormone estriol in an attempt to recapitulate the beneficial effect of pregnancy. As compared with pretreatment baseline, relapsing remitting patients treated with oral estriol (8 mg/day) demonstrated significant decreases in delayed type hypersensitivity responses to tetanus, interferon-gamma levels in peripheral blood mononuclear cells, and gadolinium enhancing lesion numbers and volumes on monthly cerebral magnetic resonance images. When estriol treatment was stopped, enhancing lesions increased to pretreatment levels. When estriol treatment was reinstituted, enhancing lesions again were significantly decreased. Based on these results, a larger, placebo-controlled trial of estriol is warranted in women with relapsing remitting multiple sclerosis. This novel treatment strategy of using pregnancy doses of estriol in multiple sclerosis has relevance to other autoimmune diseases that also improve during pregnancy.

    OBJECTIVE--To investigate the presence of abnormal illness behaviour in patients with a diagnosis of chronic fatigue syndrome. DESIGN--A cross sectional descriptive study using the illness behaviour questionnaire to compare illness behaviour scores and illness behaviour profiles of patients with chronic fatigue syndrome and patients with multiple sclerosis. SETTING--A multidisciplinary fatigue clinic and a teaching hospital neurology outpatient clinic. SUBJECTS--98 patients satisfying the Oxford criteria for chronic fatigue syndrome and 78 patients with a diagnosis of multiple sclerosis. MAIN OUTCOME MEASURE--Responses to the 62 item illness behaviour questionnaire. RESULTS--90 (92%) patients in the chronic fatigue syndrome group and 70 (90%) in the multiple sclerosis group completed the illness behaviour questionnaire. Both groups had significantly high scores on the general hypochondriasis and disease conviction subscales and significantly low scores on the psychological versus somatic concern subscale, as measured in relation to normative data. There were, however, no significant differences in the subscale scores between the two groups and the two groups had identical illness behaviour profiles. CONCLUSION--Scores on the illness behaviour questionnaire cannot be taken as evidence that chronic fatigue syndrome is a variety of abnormal illness behaviour, because the same profile occurs in multiple sclerosis. Neither can they be taken as evidence that chronic fatigue and multiple sclerosis share an aetiology. More needs to be known about the origins of illness beliefs in chronic fatigue syndrome, especially as they are important in determining outcome. PMID:7613314

    The immune system has crucial roles in the pathogenesis of multiple sclerosis. While the adaptive immune cell subsets, T and B cells, have been the main focus of immunological research in multiple sclerosis, it is now important to realize that the innate immune system also has a key involvement in regulating autoimmune responses in the central nervous system. Natural killer cells are innate lymphocytes that play vital roles in a diverse range of infections. There is evidence that they influence a number of autoimmune conditions. Recent studies in multiple sclerosis and its murine model, experimental autoimmune encephalomyelitis, are starting to provide some understanding of the role of natural killer cells in regulating inflammation in the central nervous system. Natural killer cells express a diverse range of polymorphic cell surface receptors, which interact with polymorphic ligands; this interaction controls the function and the activation status of the natural killer cell. In this review, we discuss evidence for the role of natural killer cells in multiple sclerosis and experimental autoimmune encephalomyelitis. We consider how a change in the balance of signals received by the natural killer cell influences its involvement in the ensuing immune response, in relation to multiple sclerosis.

    Abstract Multiple sclerosis (MS) is the most common autoimmune inflammatory demyelinating disease of the central nervous system, affecting over 2.3 million people worldwide. According to the National Institute of Neurological Disorders and Stroke, the age of disease onset is typically between 20 and 40 years, with a higher incidence in women. Individuals with MS experience a wide range of symptoms, including declining physical, emotional, and psychological symptoms (e.g., fatigue, imbalance, spasticity, chronic pain, cognitive impairment, bladder and bowel dysfunction, visual and speech impairments, depression, sensory disturbance, and mobility impairment). To date, both the cause of and cure for MS remain unknown. In recent years, more individuals with MS have been pursuing alternative methods of treatment to manage symptoms of the disease, including mind-body therapies such as yoga, meditation, breathing, and relaxation techniques. It has been suggested that the practice of yoga may be a safe and effective way of managing symptoms of MS. Therefore, the purpose of this paper is to summarize the most relevant literature on exercise and mind-body modalities to treat MS symptoms and, more specifically, the benefits and potential role of yoga as an alternative treatment of symptom management for individuals with MS. The article also discusses future directions for research. PMID:26270955

    Amyotrophic lateral sclerosis (ALS), Charcot's disease or Lou Gehrig's disease, is a term used to cover the spetrum of syndromes caracterized by progressive degeneration of motor neurons, a paralytic disorder caused by motor neuron degeneration. Currently, there are approximately 25,000 patients with ALS in the USA, with an average age of onset of 55 years. The incidence and prevalence of ALS are 1-2 and 4-6 per 100,000 each year, respectively, with a lifetime ALS risk of 1/600 to 1/1000. It causes progressive and cumulative physical disabilities, and leads to eventual death due to respiratory muscle failure. ALS is diverse in its presentation, course, and progression. We do not yet fully understand the causes of the disease, nor the mechanisms for its progression; thus, we lack effective means for treating this disease. In this chapter, we will discuss the diagnosis, treatment, and how to cope with impaired function and end of life based on of our experience, guidelines, and clinical trials. Nowadays ALS seems to be a more complex disease than it did two decades - or even one decade - ago, but new insights have been plentiful. Clinical trials should be seen more as experiments on pathogenic mechanisms. A medication or combination of medications that targets more than one pathogenic pathway may slow disease progression in an additive or synergistic fashion.

    Summary Two decades after the discovery that 20% of familial amyotrophic lateral sclerosis (ALS) cases were linked to mutations in the superoxide dismutase-1 (SOD1) gene, a substantial proportion of the remainder of cases of familial ALS have now been traced to an expansion of the intronic hexanucleotide repeat sequence in C9orf72. This breakthrough provides an opportunity to re-evaluate longstanding concepts regarding the cause and natural history of ALS, coming soon after the pathological unification of ALS with frontotemporal dementia through a shared pathological signature of cytoplasmic inclusions of the ubiquitinated protein TDP-43. However, with profound clinical, prognostic, neuropathological, and now genetic heterogeneity, the concept of ALS as one disease appears increasingly untenable. This background calls for the development of a more sophisticated taxonomy, and an appreciation of ALS as the breakdown of a wider network rather than a discrete vulnerable population of specialised motor neurons. Identification of C9orf72 repeat expansions in patients without a family history of ALS challenges the traditional division between familial and sporadic disease. By contrast, the 90% of apparently sporadic cases and incomplete penetrance of several genes linked to familial cases suggest that at least some forms of ALS arise from the interplay of multiple genes, poorly understood developmental, environmental, and age-related factors, as well as stochastic events.

    Objective: We examined narrative discourse in amyotrophic lateral sclerosis (ALS) to assess the role of executive functioning in support of language and the neuroanatomical basis for such support. Methods: We analyzed a semistructured speech sample in 26 patients with ALS and 19 healthy seniors for narrative discourse features of coherence. Regression analyses related a measure of discourse coherence (“local connectedness”) to gray matter atrophy and reduced white matter fractional anisotropy. Results: Patients with ALS were impaired relative to controls on measures of discourse adequacy, including local connectedness and maintenance of the theme. These discourse measures were related to measures of executive functioning but not to motor functioning. Regressions related local connectedness to gray matter atrophy in ventral and dorsal prefrontal regions and to reduced fractional anisotropy in white matter tracts mediating projections between prefrontal regions. Conclusion: Patients with ALS exhibit deficits in their ability to organize narrative discourse. These deficits appear to be related in part to executive limitations. Consistent with the hypothesis that ALS is a multisystem disorder, this deficit is related to disease in prefrontal regions. PMID:24991038

    Multiple sclerosis (MS) is a recurrent inflammatory disease of the central nervous system, which ultimately causes substantial disability in many patients. A key clinical feature of this disease is the occurrence of relapses, consisting of episodes of neurological dysfunction followed by periods of remission. This review considers in detail the importance of the occurrence of relapses to the ultimate course of MS and the impact of relap setreatment (both acutely and prophylactically) on the long-term outcome for individuals. The ultimate goal of therapy in MS is the reduction of long-term disability. Clinical trials in MS, however, typically only extend for a very short time period compared to the time it takes for disability to evolve. Consequently, short-term outcome measures that are associated with, and predict, future disability need to be identified. In this regard, not only are relapses a characteristic feature of MS, they have also been proven to be associated with the occurrence of long-term disability. Moreover, treatments that reduce the number and severity of these attacks improve the long-term prognosis.

    Abstract The pathophysiology of multiple sclerosis (MS) involves several components: redox, inflammatory/autoimmune, vascular, and neurodegenerative. All of them are supported by the intertwined lines of evidence, and none of them should be written off. However, the exact mechanisms of MS initiation, its development, and progression are still elusive, despite the impressive pace by which the data on MS are accumulating. In this review, we will try to integrate the current facts and concepts, focusing on the role of redox changes and various reactive species in MS. Knowing the schedule of initial changes in pathogenic factors and the key turning points, as well as understanding the redox processes involved in MS pathogenesis is the way to enable MS prevention, early treatment, and the development of therapies that target specific pathophysiological components of the heterogeneous mechanisms of MS, which could alleviate the symptoms and hopefully stop MS. Pertinent to this, we will outline (i) redox processes involved in MS initiation; (ii) the role of reactive species in inflammation; (iii) prooxidative changes responsible for neurodegeneration; and (iv) the potential of antioxidative therapy.

    Multiple sclerosis (MS) is an inflammatory demyelinating autoimmune disease of the central nervous system (CNS). Although the etiology of MS is unknown, genetic and environmental factors play a role. Infectious pathogens are the likely environmental factors involved in the development of MS. Pathogens associated with the development or exacerbation of MS include bacteria, such as Mycoplasma pneumoniae and Chlamydia pneumoniae, the Staphylococcus aureus-produced enterotoxins that function as superantigens, viruses of the herpes virus (Epstein-Barr virus and human herpesvirus 6) and human endogenous retrovirus (HERV) families and the protozoa Acanthamoeba castellanii. Evidence, from studies with humans and animal models, supporting the association of these various pathogens with the development and/or exacerbation of MS will be discussed along with the potential mechanisms including molecular mimicry, epitope spreading and bystander activation. In contrast, infection with certain parasites such as helminthes (Schistosoma mansoni, Fasciola hepatica, Hymenolepis nana, Trichuris trichiura, Ascaris lumbricoides, Strongyloides stercolaris, Enterobius vermicularis) appears to protect against the development or exacerbation of MS. Evidence supporting the ability of parasitic infections to protect against disease will be discussed along with a brief summary of a recent Phase I clinical trial testing the ability of Trichuris suis ova treatment to improve the clinical course of MS. A complex interaction between the CNS (including the blood-brain barrier), multiple infections with various infectious agents (occurring in the periphery or within the CNS), and the immune response to those various infections may have to be deciphered before the etiology of MS can be fully understood.

    Background: Various exercise protocols have been recommended for patients with multiple sclerosis (MS). We investigated the effects of uphill and downhill walking exercise on mobility, functional activities, and muscle strength in MS patients. Methods: Thirty-four MS patients were randomly allocated to either the downhill or uphill treadmill walking group for 12 sessions (3 times/wk) of 30 minutes' walking on a 10% negative slope (n = 17) or a 10% positive slope (n = 17), respectively. Measurements were taken before and after the intervention and after 4-week follow-up and included fatigue by Modified Fatigue Impact Scale; mobility by Modified Rivermead Mobility Index; disability by Guy's Neurological Disability Scale; functional activities by 2-Minute Walk Test, Timed 25-Foot Walk test, and Timed Up and Go test; balance indices by Biodex Balance System; and quadriceps and hamstring isometric muscles by torque of left and right knee joints. Analysis of variance with repeated measures was used to investigate the intervention effects on the measurements. Results: After the intervention, significant improvement was found in the downhill group versus the uphill group in terms of fatigue, mobility, and disability indices; functional activities; balance indices; and quadriceps isometric torque (P < .05). The results were stable at 4-week follow-up. Conclusions: Downhill walking on a treadmill may improve muscle performance, functional activity, and balance control in MS patients. These findings support the idea of using eccentric exercise training in MS rehabilitation protocols. PMID:26917996

    Several studies have reported high rates of depression in multiple sclerosis (MS) with a lifetime prevalence of approximately 50% and an annual prevalence of 20% not uncommon. Concern about the potential of new drug treatments to exacerbate or precipitate depression in MS has led to increased interest in the relation between MS and depression. This review on MS and depression identifies the following key issues: How common is depression in people with MS? Is depression in MS associated with lesions in specific regions of the central nervous system? Is there an increased risk of suicide in MS? Is there a higher than expected incidence of anxiety disorders in MS? Are fatigue and depressed mood related in MS? Is there a relation between depression and cognitive impairment in MS? Which psychosocial variables affect the development of depression in MS? Does treatment with interferon increase the risk of depression? How effective are treatments for MS patients with depression? Each of these issues is briefly reviewed with critical commentary, and some priorities for future research are suggested.

    Objective The aim of this study was to investigate the course of alexithymia and its relation with anxiety and depression in patients with multiple sclerosis (MS), over a period of 5 years. Methods Sixty-two MS patients were examined at two timepoints, 5 years apart, and they answered questionnaires collecting socio-demographic, medical, and psychological data (depression, anxiety, alexithymia). Results Our data show that emotional disorders remain stable over time in patients with MS, particularly as regards alexithymia and anxiety. Conversely, the rate of depression decreased between the two evaluations, falling from 40% to 26%. The two dimensions of alexithymia (i.e., difficulty describing and difficulty identifying feelings) were correlated with anxiety and depression, whereas the third component of alexithymia (externally oriented thinking) was independent, and was the only component to change over time, with a significant fall observed at 5 years. Conclusion Alexithymia was associated with increased severity of anxiety and attack relapses. PMID:24653957

    Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. It is typically fatal within 2–5 years of symptom onset. The incidence of ALS is largely uniform across most parts of the world, but an increasing ALS incidence during the last decades has been suggested. Although recent genetic studies have substantially improved our understanding of the causes of ALS, especially familial ALS, an important role of non-genetic factors in ALS is recognized and needs further study. In this review, we briefly discuss several major genetic contributors to ALS identified to date, followed by a more focused discussion on the most commonly examined non-genetic risk factors for ALS. We first review factors related to lifestyle choices, including smoking, intake of antioxidants, physical fitness, body mass index, and physical exercise, followed by factors related to occupational and environmental exposures, including electromagnetic fields, metals, pesticides, β-methylamino-L-alanine, and viral infection. Potential links between ALS and other medical conditions, including head trauma, metabolic diseases, cancer, and inflammatory diseases, are also discussed. Finally, we outline several future directions aiming to more efficiently examine the role of non-genetic risk factors in ALS. PMID:25709501

    The authors evaluated 74 selected patients with amyotrophic lateral sclerosis (ALS) and 201 matched controls for risk factors for ALS by a case-control design and a sequential questionnaire/interview technique to quantitate biographic data. They analyzed occupational and recreational data only for 47 male patients and 47 corresponding patient controls; data for women were insufficient. They used nonparametric analyses to evaluate five primary comparisons of ALS patients with controls: (1) more hard physical labor, p not significant (NS); (2) greater frequency of neurodegenerative disease in family members, p NS; (3) greater exposure to lead, p less than 0.05; (4) more years lived in a rural community, p NS; and (5) more trauma or major surgery, p NS. Men with ALS had worked more frequently at blue-collar jobs (although not a statistically significant difference, p = 0.10) and at welding or soldering (p less than 0.01). These results suggest that there may be an association between ALS in men and exposure to lead vapor. The limited nature of the association favors a multifactorial etiologic mechanism of ALS.

    Amyotrophic Lateral Sclerosis (ALS) is a motor neuron disease affecting upper and lower motor neurons in the central nervous system. Patients with ALS develop extensive muscle wasting and atrophy leading to paralysis and death 3 to 5 years after disease onset. The condition may be familial (fALS 10%) or sporadic ALS (sALS, 90%). The large majority of fALS cases are due to genetic mutations in the Superoxide dismutase 1 gene (SOD1, 15% of fALS) and repeat nucleotide expansions in the gene encoding C9ORF72 (∼ 40% to 50% of fALS and ∼ 10% of sALS). Studies suggest that ALS is mediated through aberrant protein homeostasis (i.e., ER stress and autophagy) and/or changes in RNA processing (as in all non-SOD1-mediated ALS). In all of these cases, animal models suggest that the disorder is mediated non-cell autonomously, i.e., not only motor neurons are involved, but glial cells including microglia, astrocytes, and oligodendrocytes, and other neuronal subpopulations are also implicated in the pathogenesis. Provided in this unit is a review of ALS rodent models, including discussion of their relative advantages and disadvantages. Emphasis is placed on correlating the model phenotype with the human condition and the utility of the model for defining the disease process. Information is also presented on RNA processing studies in ALS research, with particular emphasis on the newest ALS rodent models.

    Relapses and progression contribute to multiple sclerosis (MS) disease course, but neither the relationship between them nor the spectrum of clinical heterogeneity has been fully characterized. A hypothesis-driven, biologically informed model could build on the clinical phenotypes to encompass the dynamic admixture of factors underlying MS disease course. In this medical hypothesis, we put forth a dynamic model of MS disease course that incorporates localization and other drivers of disability to propose a clinical manifestation framework that visualizes MS in a clinically individualized way. The topographical model encapsulates 5 factors (localization of relapses and causative lesions; relapse frequency, severity, and recovery; and progression rate), visualized utilizing dynamic 3-dimensional renderings. The central hypothesis is that, like symptom recrudescence in Uhthoff phenomenon and pseudoexacerbations, progression clinically recapitulates prior relapse symptoms and unmasks previously silent lesions, incrementally revealing underlying lesion topography. The model uses real-time simulation software to depict disease course archetypes and illuminate several well-described but poorly reconciled phenomena including the clinical/MRI paradox and prognostic significance of lesion location and burden on disease outcomes. Utilization of this model could allow for earlier and more clinically precise identification of progressive MS and predictive implications can be empirically tested. PMID:27648465

    Under certain conditions or at certain stages of the disease course, multiple sclerosis (MS) and mitochondrial disorder (MID) may be differential diagnoses and thus may be confused with each other. In a 30 years old female MS was diagnosed at age 16 year upon recurrent sensory disturbances of the right lower leg, an "inflammatory" cerebrospinal fluid, and a cerebral MRI with multiple non-enhancing white matter lesions. Steroids were repeatedly given but because of rapid deterioration treatment was switched to interferon and mitoxantrone, without improvement. Fourteen years after onset the patient additionally presented with a history of rhabdomyolysis, hypothyroidism, ophthalmoparesis, anarthria, tetraspasticity, tetraparesis, and joint contractures. After MID had been diagnosed in her mother she was re-evaluated and elevated resting lactate, axonal polyneuropathy, and empty sella were additionally found. Muscle biopsy revealed myophagy, fat deposition, and type-II predominance, and biochemical investigations showed a deficiency of complex I and IV of the respiratory chain. MID was diagnosed also in the index patient. It is concluded that even if CSF investigations or imaging studies suggest MS, differentials such as MIDs need to be excluded before prescribing medication possibly toxic to a MID. An "inflammatory CSF" may also occur in MIDs.

    In comparison with the large body of evidence on cognitive functioning in adults with multiple sclerosis (MS), there is limited information on cognition in pediatric-onset MS (POMS). Unique vulnerabilities in POMS can derive from having a disease that occurs during key periods of age-expected brain growth, active myelination in the CNS, and maturation of neural networks during the learning curve and key formative years in the academic career of the patient. Therefore, the consequences of MS on developing cognitive faculties can be assessed only in the pediatric population and cannot be simply extrapolated from studies carried on in the adult population. Until the last decade, research in the pediatric population was mainly represented by small clinical series, often limited by the narrow scope of neuropsychological assessment and lack of adequate control groups. Over the last decade, however, cognitive functioning and mood-related difficulties have become an increasing concern as awareness of this population has grown. A few specialized MS centers have begun performing more systematic research in the field in order to assess the prevalence of cognitive impairments and mood-related difficulties in patients with POMS, to better characterize the neuropsychological pattern and determine the functional consequences of these problems. This chapter summarizes our current understanding of cognitive and mood-related difficulties in POMS and highlights perceived gaps in knowledge and priorities for future research.

    The cognitive and behavioral changes that can be observed in the neurodegenerative terminal disease amyotrophic lateral sclerosis (ALS), once characterized as purely a motor neuron disease, have become increasingly recognized over the past century. Detecting cognitive deficits earlier and identifying continued changes at regular intervals can lead to improved care, proactive treatments, and earlier discussions about end-of-life wishes. Although medical decisional capacity is required for every treatment decision made, its importance becomes paramount when making decisions on complex medical treatments that will invariably and significantly affect quality of life or life itself. In this review, we conducted a critical analysis of the evidence-based literature on the cognitive and behavioral impairments in ALS that can compromise medical decisional capacity. We review specific ALS-related clinical scenarios in which decisional capacity is of utmost importance and discuss a practical framework for cognitive and behavioral assessment that can be routinely and efficiently used, while being mindful of the confounding factors associated with ALS. Finally, we review models for preserving patient choices that can be used in patients with ALS to help safeguard autonomy and retain dignity toward the end of life.

    Amyotrophic lateral sclerosis (ALS), Charcot’s disease or Lou Gehrig’s disease, is a term used to cover the spetrum of syndromes caracterized by progressive degeneration of motor neurons, a paralytic disorder caused by motor neuron degeneration. Currently, there are approximately 25,000 patients with ALS in the USA, with an average age of onset of 55 years. The incidence and prevalence of ALS are 1-2 and 4-6 per 100,000 each year, respectively, with a lifetime ALS risk of 1/600 to 1/1000. It causes progressive and cumulative physical disabilities, and leads to eventual death due to respiratory muscle failure. ALS is diverse in its presentation, course, and progression. We do not yet fully understand the causes of the disease, nor the mechanisms for its progression; thus, we lack effective means for treating this disease. In this chapter, we will discuss the diagnosis, treatment, and how to cope with impaired function and end of life based on of our experience, guidelines, and clinical trials. Nowadays ALS seems to be a more complex disease than it did two decades – or even one decade – ago, but new insights have been plentiful. Clinical trials should be seen more as experiments on pathogenic mechanisms. A medication or combination of medications that targets more than one pathogenic pathway may slow disease progression in an additive or synergistic fashion. PMID:26487927

    Background: Identifying the transition from relapsing-remitting to secondary progressive multiple sclerosis (SPMS) can be challenging for clinicians. Little previous research has explored how professionals experience working with patients during this specific stage of the disease. We explored the experiences of a group of multidisciplinary professionals who support patients in the transition to SPMS to describe this stage from a professional perspective. Methods: This qualitative semistructured interview study included 11 professionals (medical, nursing, and allied health professionals; specialists and generalists) working with patients with MS in South Wales, United Kingdom. Thematic analysis of the interview data was performed. Results: Two overarching themes were identified: the transition and providing support. The transition theme comprised issues related to recognizing and communicating about SPMS. Uncertainty influenced recognizing the transition and knowing how to discuss it with patients. The providing support theme included descriptions of challenging aspects of patient care, providing support for caregivers, using the multidisciplinary team, and working within service constraints. Providing adequate psychological support and engaging patients with self-management approaches were seen as particularly challenging. Conclusions: Caring for patients in the transition to SPMS generates specific challenges for professionals. Further research on health-care interactions and patients'/professionals' experiences regarding the transition phase may help identify strategies for professional development and learning and how to optimize the patient experience at this difficult stage of disease.

    Multiple sclerosis (MS), a chronic inflammatory disease of unknown etiology, involves an immunemediated attack of the central nervous system (CNS) that produces demyelination and axonal/neuronal damage, resulting in characteristic multifocal lesions apparent on magnetic resonance imaging and a variety of neurologic manifestations. The disease pathology is characterized by multifocal lesions within the CNS, in both the white matter and gray matter, with perivenular inflammatory cell infiltrates, demyelination, axonal transection, neuronal degeneration, and gliosis. MS pathogenesis is complex, as it involves both T- and B-cell mechanisms and is heterogeneous in presentation. Relatively recently, the historical 4 core clinical categories of MS were revised in an effort to improve characterization of the clinical course, better identify where a given patient is positioned in the disease spectrum, and to guide clinical studies. In young and middle-aged adults, MS is one of the most common contributors to neurologic disability, and it exerts detrimental effects on a patient's productivity and health-related quality of life. Typically, patients with MS have a long life span, although healthcare utilization increases over time. As a consequence, the disease places a substantial burden on patients and their caregivers/families, as well as employers, the healthcare system, and society.

    Multiple sclerosis (MS) is a multi-component disease characterized by inflammation, neurodegeneration and failure of central nervous system (CNS) repair mechanisms. Immune dysregulation appears to originate with dendritic cells (antigen-presenting cells) which have an activated phenotype in individuals with MS. Dendritic cells migrate across the blood-brain barrier and induce differentiation of memory T cells into pro-inflammatory T helper 1 (Th1) and Th17 lymphocytes. In turn, induction of macrophage and microglial activation produces other pro-inflammatory cytokines and oxygen and nitric oxide radicals responsible for the demyelination and axonal loss. Other known mediators of MS pathology include CD8+ T cells and memory B cells within the CNS. Some pathological hallmarks of MS are early axonal degeneration and progressive decline of brain volume in patients with clinically isolated syndromes who progress to clinically definite MS. Many new options to interfere with the course of MS have become available in recent years. To limit inflammatory demyelinating processes and delay disease progression, intervention to control inflammation must begin as early as possible. Each distinct type of immunotherapy (immunomodulation, immunosuppression and immune-selective intervention - blockade type, sequestering type or depleting type) corresponds to a specific underlying immunopathology of MS.

    On a daily basis the quality of life of patients suffering from multiple sclerosis (MS) partially depends on social measures. These are not specific to MS. Patients often need to be helped by hospital or town social services for the numerous and complicated administrative steps to be taken. The information given to a patient is of prime importance concerning his rights, particularly his occupational rights. Many organisations have to be contacted to obtain financial and material aids, even if the latter are considered insufficient in many fields especially for improvements in accommodation. An invalidity card may entitle its holder to certain tax reductions. The competences of the COTOREP are wide-ranging and include the recognition of the handicapped worker, his training and his regarding at work, his orientation and admission into a specialised structure, the degree of his invalidity rate and should his handicap justify it, benefits such as the handicapped adults allowance and the compensatory third person's allowance. It is essential to adopt a multidisciplinary way when dealing with MS in order to provide a better care, experiments in specialised structures and networks are being undertaken. Numerous partners are taking part in these new approaches and patient associations may find their place there. Social aspects have to be taken into account as well in the way the cost of the disease is evaluated in terms of money and humanity.

    Breakthroughs in genetic studies, like whole human genome sequencing and genome-wide association studies (GWAS), have richened our knowledge of etiopathology of autoimmune diseases (AID) through discovery of genetic patterns. Nonetheless, the precise etiology of autoimmune diseases remains largely unknown. The lack of complete concordance of autoimmune disease in identical twins suggests that non-genetic factors also play a major role in determining disease susceptibility. Although there is no certain definition, epigenetics has been known as heritable alterations in gene function without changes in the nucleotide sequence. DNA methylation, histone modifications, and microRNA-associated gene expression suppression are the central mechanisms for epigenetic regulations. Multiple sclerosis (MS) is a disorder of the central nervous system (CNS), characterized by both inflammatory and neurodegenerative features. Although studies on epigenetic alterations in MS only began in the past decade, a mounting number of surveys suggest that epigenetic changes may be involved in the initiation and development of MS, probably through bridging the effects of environmental risk factors to genetics. Arming with clear understanding of epigenetic dysregulations underpins development of epigenetic therapies. Identifying agents inhibiting the enzymes controlling epigenetic modifications, particularly DNA methyltransferases and histone deacetylases, will be promising therapeutic tool toward MS. In the article underway, it is aimed to go through the recent progresses, attempting to disclose how epigenetics associates with the pathogenesis of MS and how can be used as therapeutic approach.

    As our knowledge about the etiology of multiple sclerosis (MS) increases, deterministic paradigms appear insufficient to describe the pathogenesis of the disease, and the impression is that stochastic phenomena (i.e. random events not necessarily resulting in disease in all individuals) may contribute to the development of MS. However, sources and mechanisms of stochastic behavior have not been investigated and there is no proposed framework to incorporate nondeterministic processes into disease biology. In this report, we will first describe analogies between physics of nonlinear systems and cell biology, showing how small-scale random perturbations can impact on large-scale phenomena, including cell function. We will then review growing and solid evidence showing that stochastic gene expression (or gene expression “noise”) can be a driver of phenotypic variation. Moreover, we will describe new methods that open unprecedented opportunities for the study of such phenomena in patients and the impact of this information on our understanding of MS course and therapy.

    The management of multiple sclerosis (MS) revolves around disease management, symptom management, and person management. Of these, symptom management takes up the bulk of the time of the practicing physician. Some symptoms are easily managed whereas others are more difficult. Decisions have often to be made on whether to treat or to wait and watch. This article discusses the varied symptoms of MS and the approaches to management, which involves rehabilitation, pharmacological treatments, and surgical procedures. The skilled physician managing MS should be familiar with the multiple approaches to improving the quality of life of those with MS. After the diagnosis has been established and the decisions regarding treatment approaches have been made, the talk in a typical office appointment for MS usually turns to symptom management. Thus, the majority of management decisions made by the clinician revolve around that important topic. It is symptom management that will determine quality of life for those with MS, It is the basis for improving function, and, up until twenty years ago, it was the only basis for treating MS. Now, however, we can approach treatment by disease management, symptom management, and person management. The MS specialist must be well versed in all three areas. PMID:20182577

    Objective A fatality in one multiple sclerosis (MS) patient due to acute idiopathic thrombocytopenic purpura (ITP) and a near fatality in another stimulated our interest in platelet function abnormalities in MS. Previously, we presented evidence of platelet activation in a small cohort of treatment-naive MS patients. Methods In this report, 92 normal controls and 33 stable, untreated MS patients were studied. Platelet counts, measures of platelet activation [plasma platelet microparticles (PMP), P-selectin expression (CD62p), circulating platelet microaggragtes (PAg)], as well as platelet-associated IgG/IgM, were carried out. In addition, plasma protein S activity was measured. Results Compared to controls, PMP were significantly elevated in MS (p < 0.001) and CD62p expression was also markedly elevated (p < 0.001). Both are markers of platelet activation. Platelet-associated IgM, but not IgG, was marginally elevated in MS (p = 0.01). Protein S in MS patients did not differ significantly from normal values. Conclusion Platelets are significantly activated in MS patients. The mechanisms underlying this activation and its significance to MS are unknown. Additional study of platelet activation and function in MS patients is warranted. PMID:18588683

    Mood disorders are very common among multiple sclerosis (MS) patients, but their frequency in patients with progressive course (PMS) has not been adequately researched. Our study aimed to determine the frequency of mood disorders among patients with PMS compared with those with relapsing-remitting MS (RMS) and to explore the associations with disability and disease duration. The study included consecutive outpatients affected by MS according the 2010 revised Mc Donald diagnostic criteria. Psychiatric diagnoses were determined according to DSM-IV by psychiatrists using structured interview tools (ANTAS-SCID). Demographic and clinical data of patients were also collected. Disease courses were defined according to the re-examined phenotype descriptions by the Committee and MS Phenotype Group. Intergroup comparisons were performed by Chi-square test, while logistic regression analysis was performed to assess possible factors associated with mood disorders. In total, 240 MS patients (167 women) were enrolled; of these, 18 % (45/240) had PMS. The lifetime DSM-IV major depression diagnosis (MDD) was established in 40 and 23 % of the PMS and RMS patients, respectively. Using logistic regression analysis, the presence of MDD was independent from disease duration and disability and dependent on PMS course (P = 0.02; OR 2.2). Patients with PMS presented with MDD more frequently than those with RMS, independently from disease duration and physical disability. These findings highlight the importance of considering mood disorders, especially MDD, in the management of PMS patients.

    Multiple sclerosis is the most common neurological disease of young adults that causes major disability. In Romania, it is estimated that this disease has a prevalence of 35-40 per 100,000 inhabitants. It is a disease that begins at the age of 20-40 years and is 2-3 times more common in women than in men. More than half of patients with MS develop the disease in their fertile period of life; therefore, MS patients use contraceptive methods while being under our treatment. Since several therapeutic options have been implemented with good efficiency in the disease stabilization, increasingly more patients begin to wonder about the possibility of having a child and about the possible risks of pregnancy. The evolution during pregnancy and the lactation period has been favorable, with lower relapses and side effects comparable to those in the general population. In addition, babies born to mothers with MS have not had a significantly different mean gestational age or birth weight compared to babies born to healthy mothers.

    Multiple sclerosis (MS) in children manifests with a relapsing-remitting MS (RRMS) disease course. Acute relapses consist of new neurologic deficits persisting greater than 24 hours, in the absence of intercurrent illness, and occur with a higher frequency early in the disease as compared to adult-onset RRMS. Most pediatric patients with MS recover well from these early relapses, and cumulative physical disability is rare in the first 10 years of disease. Brainstem attacks, poor recovery from a single attack, and a higher frequency of attacks portend a greater likelihood of future disability. Although prospective pediatric-onset MS cohorts have been established in recent years, there remains very limited prospective data detailing the longer-term clinical outcome of pediatric-onset MS into adulthood. Whether the advent of MS therapies, and the largely off-label access to such therapies in pediatric MS, has improved prognosis is unknown. MS onset during the key formative academic years, concurrent with active cognitive maturation, is an important determinant of long-term outcome, and is discussed in detail in another article in this supplement. Finally, increasing recognition of pediatric MS worldwide, recent launch of phase III trials for new agents in the pediatric MS population, and the clear imperative to more fully appreciate health-related quality of life in pediatric MS through adulthood highlight the need for standardized, validated, and robust outcome measures.

    Over the last 20 years, there have been significant advances in multiple sclerosis (MS) therapeutics, with regulatory approval for 13 therapies in adults by the European Medicines Agency (EMA) and Food and Drug Administration. However, there is only limited approval for interferon-β and glatiramer acetate use in children 12 years and older by the EMA. Availability of disease-modifying therapies to children and adolescents with MS is variable by region, and is extremely limited in some regions of the world. Up to 30% of children experience breakthrough disease requiring therapies beyond traditional first-line agents. Recent legislation in both the United States and Europe has mandated clinical studies for all new therapeutics applicable to children. Several clinical trials in children are underway that will provide important information regarding the efficacy and safety of newer drugs. This review summarizes the current knowledge of breakthrough disease, escalation, and induction treatment approaches in children with MS, especially pertaining to disease course and disability outcomes in this group of patients. In addition, ongoing clinical trials and approaches and challenges in conducting clinical trials in the pediatric population are discussed.

    Multiple sclerosis (MS) in children and adolescents accounts for 3-10% of the whole MS population, and is characterized by a relapsing course in almost all cases. The frequency of relapses is higher than in adult onset MS, at least in the first years of evolution. The objective of treatment is to speed the recovery after a relapse, to prevent the occurrence of relapses, and to prevent disease progression and neurodegeneration. The use of drugs for MS in children and adolescents has not been studied in clinical trials, so their use is mainly based on results from trials in adults and from observational studies. There is a consensus to treat acute relapses with intravenous high-dose corticosteroids. The possibility of preventing relapses and disease progression is based on the use of immunomodulatory agents. Interferon-beta (IFNB) and glatiramer acetate (GA) have been demonstrated to be safe and well tolerated in pediatric MS patients, and also to reduce relapse rate and disease progression. Cyclophosphamide and natalizumab could be offered as second-line treatment in patients with a poor response to IFNB or GA. New oral and injectable drugs will be available in the near future: if safe and well tolerated in the long-term follow up of adults with MS, they could be tested in the pediatric MS population.

    Objective of this study was to evaluate attentional control mechanisms in amyotrophic lateral sclerosis (ALS) using an auditory event-related potentials (ERPs) paradigm. Fifteen mild to moderate ALS patients and 15 healthy controls were administered a brief neuropsychological test battery and an ERPs paradigm assessing selective attention. Four types of auditory stimuli were presented in random order: short standard (200 Hz, 200 ms), long standard (200 Hz, 500 ms), short deviant (1000 Hz, 200 ms) and long deviant (1000 Hz, 500 ms). Participants had to respond to the long deviant stimuli only. During the task the electroencephalogram (EEG) was recorded. The N200, P300 and re-orienting negativity (RON) ERP components were analysed. Compared to controls ALS patients showed reduced amplitudes and delayed latencies of N200, P300 and RON. These results could be attributable to both an alteration in change detection resulting in a reduction of the allocation and re-orientation of attentional resources or a general slowing or reduction of neural processing efficiency in the same system. The ERPs results support the hypothesis that ALS involves extramotor cognitive functions including auditory attentional processing at all processing stages, early (200 ms) and late (300-600 ms). These data prove the usefulness and sensitivity of the auditory ERPs in detection of cognitive functions in ALS patients.

    We have evaluated the potential role of respiratory exercise by implementing specific inspiratory muscle training in a selected population of early-affected amyotrophic lateral sclerosis (ALS) patients. We studied 26 patients with ALS with normal respiratory function using two groups of patients in a parallel, control-group, randomized, delayed-start design. Patients in the first group (G1) started the active inspiratory exercise programme at entry and were followed for eight months, while the second group (G2) of patients followed a placebo exercise programme for the first four months and then active exercise for the second four-month period. The primary outcome measure was the ALSFRS. Respiratory tests, neurophysiological measurements, fatigue and quality of life scales were secondary outcomes. Analysis of covariance was used to compare changes between and within groups. Results showed that there was no significant difference between the two patient groups. Within-group analysis suggested that inspiratory exercise promotes a transient improvement in the respiratory subscore and in the maximal voluntary ventilation, peak expiratory flow, and sniff inspiratory pressure. In conclusion, there was no clear positive or negative outcome of the respiratory exercise protocol we have proposed, but we cannot rule out a minor positive effect. Exercise regimes merit more detailed clinical evaluation in ALS.

  6. Bone health in patients with multiple sclerosis.

    PubMed

    Zikan, Vit

    2011-01-01

    Multiple sclerosis (MS) is a gait disorder characterized by acute episodes of neurological defects leading to progressive disability. Patients with MS have multiple risk factors for osteoporotic fractures, such as progressive immobilization, long-term glucocorticoids (GCs) treatment or vitamin D deficiency. The duration of motor disability appears to be a major contributor to the reduction of bone strength. The long term immobilization causes a marked imbalance between bone formation and resorption with depressed bone formation and a marked disruption of mechanosensory network of tightly connected osteocytes due to increase of osteocyte apoptosis. Patients with higher level of disability have also higher risk of falls that combined with a bone loss increases the frequency of bone fractures. There are currently no recommendations how to best prevent and treat osteoporosis in patients with MS. However, devastating effect of immobilization on the skeleton in patients with MS underscores the importance of adequate mechanical stimuli for maintaining the bone structure and its mechanical competence. The physical as well as pharmacological interventions which can counteract the bone remodeling imbalance, particularly osteocyte apoptosis, will be promising for prevention and treatment of osteoporosis in patients with MS.

    Amyotrophic lateral sclerosis is a disease of which the underlying cause and pathogenesis are unknown. Cumulatative data clearly indicates an active participation by the immune system in the disease. An increasingly recognized theory suggests a non-cell autonomous mechanism, meaning that multiple cells working together are necessary for the pathogenesis of the disease. Observed immune system alterations could indicate an active participation in this mechanism. Damaged motor neurons are able to activate microglia, astrocytes and the complement system, which further can influence each other and contribute to neurodegeneration. Infiltrating peripheral immune cells appears to correlate with disease progression, but their significance and composition is unclear. The deleterious effects of this collaborating system of cells appear to outweigh the protective aspects, and revealing this interplay might give more insight into the disease. Markers from the classical complement pathway are elevated where its initiator C1q appears to derive primarily from motor neurons. Activated microglia and astrocytes are found in close proximity to dying motor neurons. Their activation status and proliferation seemingly increases with disease progression. Infiltrating monocytes, macrophages and T cells are associated with these areas, although with mixed reports regarding T cell composition. This literature review will provide evidence supporting the immune system as an important part of ALS disease mechanism and present a hypothesis to direct the way for further studies.

    Background Pain is an often underestimated and neglected symptom in amyotrophic lateral sclerosis (ALS). Methods In a cross-sectional survey, 46 patients with ALS, 46 age- and gender matched population-based controls, and 23 diseased controls with myotonic dystrophy type 2 (DM2) were screened for occurrence, type, distribution, and treatment of pain and cramps. Data were collected with the use of the short form brief pain inventory (BPI). Results Pain was reported in 78% of ALS patients,79% of DM2 patients, and 54% of controls (P < 0.05). More ALS patients than controls reported moderate to severe pain (42% vs. 20%). Pain in ALS patients interfered significantly more with daily activities than in controls (median pain interference score: 3.0 vs. 1.2, P < 0.05), especially enjoyment of life (5.0 vs. 1.0) and mood (3.0 vs. 1.0). There was no correlation between the duration of the disease and the severity of pain. Movement-induced cramps were reported in 63% of ALS patients, mostly in the distal extremities. There was no difference in the duration of ALS disease between patients reporting cramps and those who did not. Discussion Our study showed that pain was a relatively frequent symptom which had an important impact on the quality of life. Pain that requires treatment can occur at every stage of ALS.

    Seventeen multiple sclerosis (MS) patients progressing under conventional therapy (average treatment duration: 3 years) with performance status 3-4 (mean Disability Status Scale [DSS]: 82) who demonstrated circulating lymphokine inhibitor factors were selected for a monthly immunomodulatory protocol using plasmapheresis, followed by 3 days of human intravenous immunoglobulin, and low-dose methylprednisolone, cyclophosphamide, interferon-a, and interferon-g, as well as octreide. Twelve of the 17 patients presented with visual problems, 12 had lower extremity weakness or paraperesis/paralysis, and 6 had bladder/bowel dysfunction. Following 4 months of therapy, 4 recovered completely, 7 showed loss of paralysis/paraparesis, and 5 had improvement in lower extremity weakness. One patient progressed (mean DSS: 51). Lymphokine inhibitor factors declined in 14 patients with concomitant normalization of circulating immune complexes. Eight patients experienced rises in CD4 levels with stabilization of CD8 levels. Hypotension and hypocalcemia were observed during plasmapheresis. Twelve patients with amyotrophic lateral sclerosis with poor performance status also were studied. Four of the 12 improved with the regimen, whereas six stabilized disease. Similar alterations in laboratory parameters were described. The rationale for this approach is discussed. PMID:7674346

    The MSDS (multiple sclerosis documentation system) has been developed at the Department of Neurology, Technical University of Dresden, Germany, during the last 4 years. The first version of this database application has been in use since October 2000. The MSDS manages information on MS patients, their treating physicians, patient history (symptoms, other diseases, biographical history, family history, habits, medication), clinical signs, results of laboratory examinations (blood chemistry, autoantibodies, borrelia serology, evoked potentials, cranial and spinal cord magnetic resonance imaging), clinical scores relevant for MS, and biosamples. In principle, MSDS allows online data input and semiautomatically generates reports to all general practitioners and neurologists treating the respective patient. Patient information sheets and internal treatment guidelines are part of the system. During a 3-month evaluation, the first version of MSDS was tested at eight university multiple sclerosis ambulatory care units and one general neurology hospital. The overall judgement was favorable. Suggestions for changes and improvements, as well as practical experiences, were considered when developing MSDS 2.0, which will be available by the end of 2001.

    Strokes are the main neurological manifestation of antiphospholipid syndrome. Other clinical presentations are possible and may mimic classic symptoms of multiple sclerosis (MS). A 46-year-old woman, with a history of two miscarriages, presented four subacute neurological episodes (optic neuritis, right facial paralysis, paraparesis of the thigh, and right brachial monoparesis). Using McDonald criteria, the diagnosis of multiple sclerosis was retained. Because of the occurrence of thrombocytopenia during a final relapse, we reconsidered the diagnosis of MS. Search for antiphospholipid antibodies was positive. All clinical manifestations and complementary tests were compatible with the diagnosis of antiphospholipid syndrome associated with multiple sclerosis. Given the great similarity of clinical, radiological and biological findings in the two diseases, non-thrombotic neurological manifestations of antiphospholipid syndrome can be difficult to distinguish from MS associated with antiphospholipid syndrome.

  12. Role of interleukin-13 in fibrosis, particularly systemic sclerosis.

    PubMed

    O'Reilly, Steven

    2013-01-01

    Chronic inflammation can lead to altered extracellular matrix deposition and ultimately fibrosis. Interleukin-13 (IL-13) is a cytokine that was found to promote IgE class switching and inhibit proinflammatory cytokines. However, it is now recognized as an important mediator in allergy and most importantly fibrosis. Indeed, animal studies with genetically deleted mice have demonstrated its critical role in fibrosis and although it shares over lapping functions with IL-4 it is the dominant cytokine in fibrosis. Systemic sclerosis is an autoimmune disease in which there is chronic inflammation and fibrosis. The disease is associated with a Th2 polarization and IL-13 levels are elevated both in the blood and in the skin of patients. This review will examine the role of IL-13 in driving fibrosis with a particular emphasis on systemic sclerosis as a prototypical fibrotic disease. It will highlight recent research into the role of IL-13 and how this cytokine may be targeted in systemic sclerosis.

    Approximately 50% of patients with the genetic disease tuberous sclerosis complex present with autism spectrum disorder. Although a number of studies have investigated the link between autism and tuberous sclerosis complex, the etiology of autism spectrum disorder in these patients remains unclear. Abnormal cerebellar function during critical phases of development could disrupt functional processes in the brain, leading to development of autistic features. Accordingly, the authors review the potential role of cerebellar dysfunction in the pathogenesis of autism spectrum disorder in tuberous sclerosis complex. The authors also introduce conditional knockout mouse models of Tsc1 and Tsc2 that link cerebellar circuitry to the development of autistic-like features. Taken together, these preclinical and clinical investigations indicate the cerebellum has a profound regulatory role during development of social communication and repetitive behaviors.

    Trichloroethylene (CHCL = CCL2) is a colorless aliphatic organic solvent with both historical use in medicine as an anesthetic agent and current use in industry as a degreasing agent. Although neither the etiology nor pathogenesis of progressive systemic sclerosis (scleroderma) has been established, this disease has been associated with a wide variety of seemingly unrelated compounds, including exposure to organic solvents. The authors describe a 47-year-old woman with previous excellent health who developed fatal progressive systemic sclerosis after a single 2.5-hour predominantly dermal exposure to trichloroethylene. During a period of 10 months the patient developed proximal scleroderma, reflux esophagitis, microangiopathic hemolytic anemia, restrictive pulmonary disease, pericarditis with effusion, and renal insufficiency with severe hypertension. Renal and skin biopsies were consistent with progressive systemic sclerosis.

    In this mixed-methods study, utilization data for disease-modifying therapies were reviewed to determine the adherence rate among our pediatric multiple sclerosis cohort. Adolescents were interviewed to explore their experiences with multiple sclerosis and the impact of peer relationships on adherence to treatment. Seventeen adolescents (6 male, 11 female) started interferon beta or glatiramer acetate before age 18. The mean age at first drug start date was 15.8 years. Eight of the adolescents (47%) discontinued treatment after a median duration of 20 months. Many of the adolescents struggled to integrate the injections into their daily lives, with peers either facilitating or impeding this transition. In conclusion, adolescents in this cohort had difficulty adhering to disease-modifying therapies, and peers played an important role in mediating their adjustment to multiple sclerosis. Specific strategies are required to improve adolescents' adherence to treatment, including less intrusive options and enhancing peer support.

    We present a case of fulminant diffuse systemic sclerosis (dSSc) developed after the aortic valve replacement followed by fatal congestive heart failure within the 6 months from the initial symptoms. A 61-year-old male developed rapidly progressive diffuse systemic sclerosis following aortic valve replacement due to stenosis of bicuspid aortic valve. He presented with diarrhoea, weight loss, mialgia and arthralgia after cardiac surgery. Heart failure, due to myocardial fibrosis, was noted as a cause of death. We hypothesize that artificial materials like the ones used in mechanical valves or silicon materials in breast implants may induce fulminant course of pre-existing systemic sclerosis or create a new onset in predisposed individual.

    Purpose of review Systemic sclerosis is commonly complicated by pulmonary arterial hypertension (PAH-SSc) and is a leading cause of death in this population. We will review existing challenges and recent advances in the treatment of this disease. Recent findings Traditionally employed outcome measures in pulmonary arterial hypertension research may not be applicable in PAH-SSc. Importantly, new therapies that target abnormal cellular proliferation in the pulmonary vasculature are currently under investigation and may be particularly relevant to PAH-SSc. Summary Pulmonary arterial hypertension complicating systemic sclerosis occurs commonly and portends a poor prognosis. However, recent advances in our understanding of the disease in the context of systemic sclerosis may lead to novel diagnostic and therapeutic strategies that will ultimately improve quality of life and survival in this population.

  19. Remyelination strategies in multiple sclerosis: a critical reflection.

    PubMed

    Kipp, Markus

    2016-01-01

    Remyelination is the natural repair mechanism of demyelination and can be a highly efficient process in multiple sclerosis. However, in the majority of lesions, this regenerative approach is incomplete or fails. It is believed that remyelination protects against progressive axonal damage and thus long-term disability in patients with multiple sclerosis. For this reason, therapeutic promotion of remyelination represents an attractive option for preventing disease progression. In this editorial we casts a critical eye over the most frequently used experimental settings which aim to uncover potential remyelination promoting drugs. This article reflects upon the personal opinion of the author who currently used animal models allow to assess the potency of pharmacological interventions to accelerate, but not to induce myelin repair. Furthermore, it is discussed how remyelination and neuroprotection might well be two separate entities. Thus, induction of remyelination does not necessarily prevent disease progression in multiple sclerosis patients.

    Diffuse systemic sclerosis carries a high morbidity and mortality. The Prospective Registry of Early Systemic Sclerosis (PRESS), a multicentre incident cohort study of patients with early diffuse cutaneous systemic sclerosis, has the goal of advancing the understanding of disease pathogenesis and identifying novel biomarkers. In this review, PRESS investigators discuss the evidence pertaining to the more commonly used treatments for early diffuse SSc skin disease including methotrexate, mycophenolate, cyclophosphamide, azathioprine, and intravenous immunoglobulin. This review highlights the unmet need for effective treatment in early diffuse SSc as well as its more rigorous study. Nonetheless, the PRESS investigators aim to decrease intra- and inter-institutional variability in prescribing in order to improve the understanding of the clinical course of early diffuse SSc skin disease.

    Mitochondrial dysfunction is implicated in amyotrophic lateral sclerosis, where the progressive degeneration of motor neurons results in muscle atrophy, paralysis and death. Abnormalities in both central nervous system and muscle mitochondria have previously been demonstrated in patient samples, indicating systemic disease. In this case-control study, venous blood samples were acquired from 24 amyotrophic lateral sclerosis patients and 21 age-matched controls. Platelets and peripheral blood mononuclear cells were isolated and mitochondrial oxygen consumption measured in intact and permeabilized cells with additions of mitochondrial substrates, inhibitors and titration of an uncoupler. Respiratory values were normalized to cell count and for two markers of cellular mitochondrial content, citrate synthase activity and mitochondrial DNA, respectively. Mitochondrial function was correlated with clinical staging of disease severity. Complex IV (cytochrome c-oxidase)-activity normalized to mitochondrial content was decreased in platelets from amyotrophic lateral sclerosis patients both when normalized to citrate synthase activity and mitochondrial DNA copy number. In mononuclear cells, complex IV-activity was decreased when normalized to citrate synthase activity. Mitochondrial content was increased in amyotrophic lateral sclerosis patient platelets. In mononuclear cells, complex I activity declined and mitochondrial content increased progressively with advancing disease stage. The findings are, however, based on small subsets of patients and need to be confirmed. We conclude that when normalized to mitochondria-specific content, complex IV-activity is reduced in blood cells from amyotrophic lateral sclerosis patients and that there is an apparent compensatory increase in cellular mitochondrial content. This supports systemic involvement in amyotrophic lateral sclerosis and suggests further study of mitochondrial function in blood cells as a future biomarker for the

  2. Increased SA in NPR1-silenced plants antagonizes JA and JA-dependent direct and indirect defenses in herbivore-attacked Nicotiana attenuata in nature.

    The phytohormone jasmonic acid (JA) is known to mediate herbivore resistance, while salicylic acid (SA) and non-expressor of PR-1 (NPR1) mediate pathogen resistance in many plants. Herbivore attack on Nicotiana attenuata elicits increases in JA and JA-mediated defenses, but also increases SA levels and Na-NPR1 transcripts from the plant's single genomic copy. SA treatment of wild-type plants increases Na-NPR1 and Na-PR1 transcripts. Plants silenced in NPR1 accumulation by RNAi (ir-npr1) are highly susceptible to herbivore and pathogen attack when planted in their native habitat in Utah. They are also impaired in their ability to attract Geocorus pallens predators, due to their decreased ability to release cis-alpha-bergamotene, a JA-elicited volatile 'alarm call'. In the glasshouse, Spodoptera exigua larvae grew better on ir-npr1 plants, which had low levels of JA, JA-isoleucine/leucine, lipoxygenase-3 (LOX3) transcripts and JA-elicited direct defense metabolites (nicotine, caffeoyl putrescine and rutin), but high levels of SA and isochorismate synthase (ICS) transcripts, suggesting de novo biosynthesis of SA. A microarray analysis revealed downregulation of many JA-elicited genes and upregulation of SA biosynthetic genes. JA treatment restored nicotine levels and resistance to S. exigua in ir-npr1 plants. We conclude that, during herbivore attack, NPR1 negatively regulates SA production, allowing the unfettered elicitation of JA-mediated defenses; when NPR1 is silenced, the elicited increases in SA production antagonize JA and JA-related defenses, making the plants susceptible to herbivores.

    Cross sectional echocardiography, 12 lead electrocardiography, and 24 hour ambulatory electrocardiography were performed in eleven patients with tuberous sclerosis. Echocardiography showed single or multiple intramyocardial masses, most commonly in the ventricular septum, suggestive of rhabdomyomata in seven of the eleven cases. One patient with a normal echocardiogram showed ventricular pre-excitation on electrocardiography, with tachycardias of 180 beats per minute on ambulatory monitoring. Sinus bradycardia, sinus tachycardia, and supraventricular tachycardia were also seen, but their importance is uncertain. Echocardiography and electrocardiography should be routinely performed in the assessment of patients with tuberous sclerosis and ambulatory electrocardiography should be considered in those with seizures that respond poorly to anticonvulsants.

    Amyotrophic lateral sclerosis is a fatal neurodegenerative disease characterized by progressive degeneration of motor neurons which leads to muscular atrophy, paralysis and death in 3-5 years from starting symptoms. This disorder is accompanied by noteworthy spinal inflammation mediated in particular by microglia and mast cells. No effective therapy is available. This report describes the effects of administering the anti-inflammatory agent palmitoylethanolamide in a case of sporadic amyotrophic lateral sclerosis. Palmitoylethanolamide treatment led to an improved clinical picture, as evidenced by electromyographic analysis and pulmonary function. Conceivably, the action of palmitoylethanolamide could result, in part, from its ability to dampen mast cell and microglia activation.

    Hematopoietic stem cell transplantation may “reset” the immune reconstitution and induce self tolerance of autoreactive lymphocytes, and has been explored in the treatments for systemic sclerosis. Phase I/II trials have shown a satisfactory risk benefit ratio. The true benefit will be identified by two ongoing prospective, randomized phase III trials. Multipotent mesenchymal stromal cells (MSCs) possess antiproliferative, anti-inflammatory, and immunosuppressive properties. The use of MSCs has showed successful responses in patients with severe steroid-resistant acute graft versus host disease in phase II trials, and may be a potentially promising option for patients with systemic sclerosis.

    The neuropathologic molecular signature common to almost all sporadic amyotrophic lateral sclerosis (ALS) and most familial ALS is TDP-43 immunoreactive neuronal cytoplasmic inclusions. The neuropathologic and molecular neuropathologic features of ALS variants, primarily lateral sclerosis and progressive muscular atrophy, are less certain but also seem to share the primary features of ALS. Genetic causes, including mutations in SOD1, TDP-43, FUS, and C9orf72, all have distinctive molecular neuropathologic signatures. Neuropathology will continue to play an increasingly key role in solving the puzzle of ALS pathogenesis.

    Here, we describe an atypical case of systemic sclerosis in its diffuse cutaneous form with acute and rapid progression of the cutaneous condition, without any systemic manifestations and the infrequent formation of bullae, showing the importance of diagnosis and early treatment in such cases. This case also shows that special measures should be taken for bullous cutaneous lesions and ulcerations resulting from serious sclerosis, which are entry points and increase morbidity and risk of death. Other prognostic factors include age, ESR and renal and pulmonary involvement. Capillaroscopies can be useful predictors of greater severity of systemic scleroderma, revealing a greater link with systemic, rather than cutaneous, involvement. PMID:24346886

In the growing field of new and potent drugs for multiple sclerosis (MS), we review the current data concerning infections and prevention of infectious diseases. This is of importance for recently licensed and future MS treatment options, but also for long-term established therapies for MS. Some of the disease-modifying therapies (DMT) go along with threats of specific severe infections or complications, which require a more intensive long-term monitoring and multi-disciplinary surveillance.

    2017-04-01

    Multiple sclerosis is a major cause of neurological disability, which accrues predominantly during progressive forms of the disease. Although development of multifocal inflammatory lesions is the underlying pathological process in relapsing-remitting multiple sclerosis, the gradual accumulation of disability that characterises progressive multiple sclerosis seems to result more from diffuse immune mechanisms and neurodegeneration. As a result, the 14 anti-inflammatory drugs that have regulatory approval for treatment of relapsing-remitting multiple sclerosis have little or no efficacy in progressive multiple sclerosis without inflammatory lesion activity. Effective therapies for progressive multiple sclerosis that prevent worsening, reverse damage, and restore function are a major unmet need. In this Series paper we summarise the current status of therapy for progressive multiple sclerosis and outline prospects for the future.

    Abstract Background: Fatigue is commonly reported by people with multiple sclerosis (MS). Comorbidity is also common in MS, but its association with the presence of fatigue or fatigue changes over time is poorly understood. Methods: Nine hundred forty-nine people with definite MS were recruited from four Canadian centers. The Fatigue Impact Scale for Daily Use and a validated comorbidity questionnaire were completed at three visits over 2 years. Participants were classified into groups with no fatigue versus any fatigue. Logistic regression was used to determine the relationship between fatigue and each comorbidity at baseline, year 1, year 2, and overall. Results: The incidence of fatigue during the study was 38.8%. The prevalence of fatigue was greater in those who were older (P = .0004), had a longer time since symptom onset (P = .005), and had greater disability (P < .0001). After adjustment, depression (odds ratio [OR], 2.58; 95% confidence interval [CI], 2.03–3.27), irritable bowel syndrome (OR, 1.71; 95% CI, 1.18–2.48), migraine (OR, 1.69; 95% CI, 1.27–2.27), and anxiety (OR, 1.57; 95% CI, 1.15–2.16) were independently associated with fatigue that persisted during the study. There was also an individual-level effect of depression on worsening fatigue (OR, 1.49; 95% CI, 1.08–2.07). Conclusions: Comorbidity is associated with fatigue in MS. Depression is associated with fatigue and with increased risk of worsening fatigue over 2 years. However, other comorbid conditions commonly associated with MS are also associated with persistent fatigue, even after accounting for depression. Further investigation is required to understand the mechanisms by which comorbidities influence fatigue. PMID:27134583

    Background Celiac disease (CD) is a common systemic disease related to a permanent intolerance to gluten and is often associated with different autoimmune and neurological diseases. Its mean prevalence in the general population is 1-2% worldwide. Our aim was to study the prevalence of celiac disease in a prospective series of Multiple Sclerosis (MS) patients and their first-degree relatives. Methods We analyzed the prevalence of serological, histological and genetic CD markers in a series of 72 MS patients and in their 126 first-degree relatives, compared to 123 healthy controls. Results Tissue IgA-anti-transglutaminase-2 antibodies were positive in 7 MS patients (10%), compared to 3 healthy controls (2.4%) (p < 0.05). OR: 5.33 (CI-95%: 1.074-26.425). No differences were found in HLA-DQ2 markers between MS patients (29%) and controls (26%) (NS). We detected mild or moderate villous atrophy (Marsh III type) in duodenal biopsies, in 8 MS patients (11.1%). We also found a high proportion of CD among first-degree relatives: 23/126 (32%). Several associated diseases were detected, mainly dermatitis 41 (57%) and iron deficiency anemia in 28 (39%) MS patients. We also found in them, an increased frequency of circulating auto-antibodies such as anti-TPO in 19 (26%), ANA in 11 (15%) and AMA in 2 (3%). Conclusions We have found an increased prevalence of CD in 8 of the 72 MS patients (11.1%) and also in their first-degree relatives (23/126 [32%]). Therefore, increased efforts aimed at the early detection and dietary treatment of CD, among antibody-positive MS patients, are advisable. PMID:21385364

    Early reports often ignored pain as an important symptom in multiple sclerosis (MS). Pain prevalence figures in MS from European countries other than Portugal range between 40 and 65%. To our knowledge there is no published data in English on pain in MS in Portugal. We describe the demographic and clinical characteristics, with an emphasis on pain, of 85 MS patients followed-up in a Portuguese hospital, contributing to pain epidemiology in MS. Patients were interviewed sequentially after their regular appointments at the MS clinic; patients with pain completed The Brief Pain Inventory and The McGill Pain Questionnaire (MPQ). The prevalence of pain found was 34%. Headache and back pain were the most common anatomical sites described, followed by upper and lower limbs. Intensity of pain in an 11-point scale was, for the maximum pain intensity 6.7 ± 1.8, for the minimum pain intensity 2.2 ± 2.0, for the mean pain intensity 4.5 ± 1.5, and for the actual pain intensity 2.4 ± 2.9. Pain interfered significantly with general activity, mood, work, social relations, and enjoyment of life. All MS patients with pain employed words from both the sensory and affective categories of the MPQ to describe it. Patient pain descriptions’ included the word “hot-burning” in 59% of the cases, common in the report of central pain, but neuropathic pain medications were only used by 10% of them. Pain is an important symptom in Portuguese patients with MS, not only because of the high prevalence found, concordant with other European countries, but also because of its interference with quality-of-life.

    Multiple sclerosis (MS) is an inflammatory demyelinating autoimmune disease of the central nervous system (CNS). Although the etiology of MS is unknown, genetic and environmental factors play a role. Infectious pathogens are the likely environmental factors involved in the development of MS. Pathogens associated with the development or exacerbation of MS include bacteria, such as Mycoplasma pneumoniae and Chlamydia pneumoniae, the Staphylococcus aureus-produced enterotoxins that function as superantigens, viruses of the herpes virus (Epstein-Barr virus and human herpesvirus 6) and human endogenous retrovirus (HERV) families and the protozoa Acanthamoeba castellanii. Evidence, from studies with humans and animal models, supporting the association of these various pathogens with the development and/or exacerbation of MS will be discussed along with the potential mechanisms including molecular mimicry, epitope spreading and bystander activation. In contrast, infection with certain parasites such as helminthes (Schistosoma mansoni, Fasciola hepatica, Hymenolepis nana, Trichuris trichiura, Ascaris lumbricoides, Strongyloides stercolaris, Enterobius vermicularis) appears to protect against the development or exacerbation of MS. Evidence supporting the ability of parasitic infections to protect against disease will be discussed along with a brief summary of a recent Phase I clinical trial testing the ability of Trichuris suis ova treatment to improve the clinical course of MS. A complex interaction between the CNS (including the blood-brain barrier), multiple infections with various infectious agents (occurring in the periphery or within the CNS), and the immune response to those various infections may have to be deciphered before the etiology of MS can be fully understood.

    Apathy has been recognized as a frequent symptom in multiple sclerosis (MS) but uncertainty remains about its prevalence and clinical correlates. Therefore, the objective of this work was to assess the prevalence of apathy in patients with MS and to identify clinical and demographic correlates. A case-control study with 30 patients and 30 healthy controls matched for age, gender and education was performed. Apathy diagnosis was established using Robert et al.'s criteria. Additionally, apathy was assessed using the 10-item short version of the clinical-rated Apathy Evaluation Scale (AES-C-10). The Beck Depression Inventory (BDI), Modified Fatigue Impact Scale (MFIS), and Montreal Cognitive Assessment (MoCA) were used to evaluate depression, fatigue and cognitive impairment, respectively. Apathy prevalence in MS patients was 43.3%. Patients with MS had higher AES-C-10 scores than controls (13.9 vs. 12.0, p=0.015). Patients with apathy presented a higher proportion of males (53.8% vs. 11.8%, p=0.02), lower educational level (53.8% vs. 11.8% of patients with up to 9years of education), higher scores on cognitive dimension of MFIS (18.0 vs. 8.0, p=0.048) and BDI (13.0 vs. 7.0, p=0.035) and worse performance on MoCA (24.0 vs. 26.0, p=0.028). Gender was the only independent predictor of apathy, with men presenting a higher risk compared to women (OR: 9.62; 95%CI: 1.02-90.61; p=0.048). In conclusion, apathy is a common neuropsychiatric disorder in MS and it is probably underdiagnosed. Male patients seem to have an increased risk of apathy, and this finding may be related to the generally more unfavorable course of MS in men.

    Systemic sclerosis (SSc) is a generalised autoimmune disease, of yet unknown origin, with two major clinical subsets: the limited (lcSSc) and the diffuse cutaneous (dcSSc) forms, which can be distinguished by the extent of skin involvement, the autoantibody profile and the pattern of organ involvement. With an incidence of 1/10(5), SSc affects around 250,000 people in Europe and is responsible for significant morbidity with a 5-year mortality rate of at least 30% of all patients. In patients with rapidly progressive dcSSc, the 5-year mortality is estimated to be 40-50%. Hematopoietic stem cell transplantation (HSCT), mostly autologous but also allogeneic in some specific cases, has been employed worldwide since 1996 as a new therapeutic strategy in patients with a poor prognosis. In 2007, 150 HSCT procedures have been reported in the EBMT data base. We review herein both the short and the long-term reports from the various European and North American phase I-II studies, which have shown that autologous HSCT in selected patients with severe dcSSc results in sustained improvement of skin thickening and stabilisation of organ function up to seven years after transplantation. Based on these promising results, ongoing phase III trials have been designed in parallel, both in Europe (ASTIS) and in North America (SCOTT) aiming to analyse the respective benefits from autologous HSCT respectively without or with high dose irradiation. This review reports the current data concerning the effects of HSCT on survival, skin, and major organ function in patients with severe dcSSc.

    Objective Multiple sclerosis (MS) develops as a result of environmental influences on the genetically susceptible. Siblings of people with MS have an increased risk of both MS and demonstrating asymptomatic changes in keeping with MS. We set out to develop an MS risk score integrating both genetic and environmental risk factors. We used this score to identify siblings at extremes of MS risk and attempted to validate the score using brain MRI. Methods 78 probands with MS, 121 of their unaffected siblings and 103 healthy controls were studied. Personal history was taken, and serological and genetic analysis using the illumina immunochip was performed. Odds ratios for MS associated with each risk factor were derived from existing literature, and the log values of the odds ratios from each of the risk factors were combined in an additive model to provide an overall score. Scores were initially calculated using log odds ratio from the HLA-DRB1*1501 allele only, secondly using data from all MS-associated SNPs identified in the 2011 GWAS. Subjects with extreme risk scores underwent validation studies. MRI was performed on selected individuals. Results There was a significant difference in the both risk scores between people with MS, their unaffected siblings and healthy controls (p<0.0005). Unaffected siblings had a risk score intermediate to people with MS and controls (p<0.0005). The best performing risk score generated an AUC of 0.82 (95%CI 0.75–0.88). Interpretations The risk score demonstrates an AUC on the threshold for clinical utility. Our score enables the identification of a high-risk sibling group to inform pre-symptomatic longitudinal studies. PMID:27802296

  1. Clutter Management for Individuals with Multiple Sclerosis

    PubMed Central

    2014-01-01

    Background: Although there is substantial anecdotal evidence that clutter is common among people with multiple sclerosis (MS), the literature contains no reports of studies on the actual prevalence of the problem or its impact on functional performance in this population. Clutter promotes confusion and places individuals in potentially dangerous situations by increasing their risks of falling, losing medications, and misplacing important documents. In addition, it may negatively affect activities of daily living (ADLs). Many common MS symptoms such as decreased mobility, visual or cognitive changes, fatigue, and depression can exacerbate clutter accumulation, which in turn can have detrimental effects on physical, financial, emotional, cognitive, and social functioning. It is critical for MS clinicians to address clutter management in order to improve patients' overall functional independence and participation. Methods: A clutter reduction protocol was developed and implemented at our institution for individuals with MS. Our group program addresses psychosocial issues preventing organization and offers practical strategies for clutter removal and management to improve performance in ADLs. A clutter questionnaire is administered to individuals before and after their participation in the group program. Results: Anecdotal reports indicate that the intervention helped to reduce clutter, promote a more realistic attitude toward “possessions,” and establish a sense of accomplishment in controlling one's environment. Participants also reported fewer falls, feeling less isolated, increased ease in finding their medications, and a general sense of cognitive clarity in accomplishing ADLs. Outcome assessments are now being developed to objectively measure these effects as well as the prevalence of clutter within the MS population. Conclusions: Clutter management is an important area for MS clinicians to address because it can significantly affect patients' functioning

    Abstract Peak age at onset of systemic sclerosis (SSc) is between 20 and 50 years, although SSc is also described in both young and elderly patients. We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.2 ± 6.8 years. Based on the mean ± 1 standard deviation (SD) of age at disease onset (45 ± 15 yr) of the whole series, patients were classified into 3 groups: age ≤30 years (early onset), age between 31 and 59 years (standard onset), and age ≥60 years (late onset). We compared initial and cumulative manifestations, immunologic features, and death rates. The early-onset group included 195 patients; standard-onset group, 651; and late-onset, 191 patients. The early-onset group had a higher prevalence of esophageal involvement (72% in early-onset compared with 67% in standard-onset and 56% in late-onset; p = 0.004), and myositis (11%, 7.2%, and 2.9%, respectively; p = 0.009), but a lower prevalence of centromere antibodies (33%, 46%, and 47%, respectively; p = 0.007). In contrast, late-onset SSc was characterized by a lower prevalence of digital ulcers (54%, 41%, and 34%, respectively; p < 0.001) but higher rates of heart conduction system abnormalities (9%, 13%, and 21%, respectively; p = 0.004). Pulmonary hypertension was found in 25% of elderly patients and in 12% of the youngest patients (p = 0.010). After correction for the population effects of age and sex, standardized mortality ratio was shown to be higher in younger patients. The results of the present study confirm that age at disease onset is associated with differences in clinical presentation and outcome in SSc patients. PMID:24646463

    Objective: The aim of this study was to test the safety of diazoxide and to search for signs of efficacy in patients with relapsing-remitting multiple sclerosis (RRMS). Methods: In this multicenter, randomized, placebo-controlled, double-blind trial (treatment allocation was concealed), 102 patients with RRMS were randomized to receive a daily oral dose of diazoxide (0.3 and 4 mg/d) or placebo for 24 weeks (NCT01428726). The primary endpoint was the cumulative number of new T1 gadolinium-enhancing lesions per patient, recorded every 4 weeks from week 4 to week 24. Secondary endpoints included brain MRI variables such as the number of new/enlarging T2 lesions and the percentage brain volume change (PBVC); clinical variables such as the percentage of relapse-free patients, relapse rate, and change in the Expanded Disability Status Scale score; and safety and tolerability. Results: Diazoxide was well-tolerated and it produced no serious adverse events other than 1 case of Hashimoto disease. At the 2 doses tested, diazoxide did not improve the primary endpoint or the MRI and clinical variables related to the presence of new lesions or relapses. Patients treated with diazoxide showed reduced PBVC compared with the placebo group, although such changes could be confounded by the higher disease activity of the treated group and the vascular effects of diazoxide. Conclusion: At the doses tested, oral diazoxide did not decrease the appearance of new lesions evident by MRI. The effects in slowing the progression of brain atrophy require further validation. Classification of evidence: This study provides Class I evidence that for patients with RRMS, diazoxide (0.3 and 4 mg/d) does not significantly change the number of new MRI T1 gadolinium-enhancing lesions.

    Objectives: We aimed to investigate the association between polymorphisms located in type I interferon (IFN)-induced genes, genes belonging to the toll-like receptor (TLR) pathway, and genes encoding neurotransmitter receptors and the response to IFN-β treatment in patients with multiple sclerosis (MS). Methods: In a first or screening phase of the study, 384 polymorphisms were genotyped in 830 patients with MS classified into IFN-β responders (n = 416) and nonresponders (n = 414) according to clinical criteria. In a second or validation phase, the most significant polymorphisms associated with IFN-β response were genotyped in an independent validation cohort of 555 patients with MS (281 IFN-β responders and 274 nonresponders). Results: Seven single nucleotide polymorphisms (SNPs) were selected from the screening phase for further validation: rs832032 (GABRR3; p = 0.0006), rs6597 (STUB1; p = 0.019), rs3747517 (IFIH1; p = 0.010), rs2277302 (PELI3; p = 0.017), rs10958713 (IKBKB; p = 0.003), rs2834202 (IFNAR1; p = 0.030), and rs4422395 (CXCL1; p = 0.017). None of these SNPs were significantly associated with IFN-β response when genotyped in an independent cohort of patients. Combined analysis of these SNPs in all patients with MS (N = 1,385) revealed 2 polymorphisms associated with IFN-β response: rs2277302 (PELI3; p = 0.008) and rs832032 (GABRR3; p = 0.006). Conclusions: These findings do not support an association between polymorphisms located in genes related to the type I IFN or TLR pathways or genes encoding neurotransmitter receptors and the clinical response to IFN-β. Nevertheless, additional genetic and functional studies of PELI3 and GABRR3 are warranted. PMID:26445728

    We herein report an autopsy case of the Marburg variant of multiple sclerosis (MS). A 29-year-old woman developed acute and progressive neurological symptoms. A diagnosis of MS was suspected based on the patient's clinical background and brain MRI findings and the lack of evidence of malignancy on a brain biopsy. Despite the administration of typical treatment for MS, a fatal outcome occurred three months after disease onset. The autopsy revealed multiple inflammatory demyelinating lesions in the central nervous system. In addition, two noteworthy histopathological features were observed compared with prototypical MS. We evaluate the pathogenic differences between the Marburg type and prototypical MS by discussing the neuropathology and cerebrospinal fluid (CSF) findings of our case.

    Background The available clinical outcome measures of disability in multiple sclerosis are not adequately responsive or sensitive. Objective To investigate the feasibility of inertial sensor-based gait analysis in multiple sclerosis. Methods A cross-sectional study of 80 multiple sclerosis patients and 50 healthy controls was performed. Lower-limb kinematics was evaluated by using a commercially available magnetic inertial measurement unit system. Mean and standard deviation of range of motion (mROM, sROM) for each joint of lower limbs were calculated in one minute walking test. A motor performance index (E) defined as the sum of sROMs was proposed. Results We established two novel observer-independent measures of disability. Hip mROM was extremely sensitive in measuring lower limb motor impairment, being correlated with muscle strength and also altered in patients without clinically detectable disability. On the other hand, E index discriminated patients according to disability, being altered only in patients with moderate and severe disability, regardless of walking speed. It was strongly correlated with fatigue and patient-perceived health status. Conclusions Inertial sensor-based gait analysis is feasible and can detect clinical and subclinical disability in multiple sclerosis. PMID:26863109

    Our present understanding of the aetiology and pathogenesis of multiple sclerosis is discussed in relation to the views of Sir William Gowers. He perceived that both environmental and genetic factors might be implicated in the aetiology of the disease. Evidence for the former was first reported in 1903, but has become convincing only in the past 20 years; the nature of the environmental factor remains obscure. Evidence for a genetic influence on susceptibility has accumulated since the 1930s, the most compelling coming from the recent Canadian twin study. The number and mode of operation of the genetic factors is still uncertain, but there is evidence for the implication of genetically controlled cellular immune mechanisms in the pathogenesis of the disease. The precise relationship between transient changes in immunological status and the development of new lesions has yet to be defined; magnetic resonance imaging (MRI) promises to play a significant role in this analysis because of its sensitivity in detecting abnormalities in multiple sclerosis. MRI is not in itself specific; it is probable that the similar appearances in multiple sclerosis and cerebral vascular disease both derive at least in part from the influence of astrocytic gliosis on proton content and distribution. The significance of the gliosis is uncertain. Gowers believed that the primary defect in multiple sclerosis lay in the astrocyte. Recent observations on the immunological functions of this cell in vitro suggest that it could be involved early in the pathogenesis of the lesion. Images PMID:2936869

    2011-03-01

    Systemic sclerosis is a rare disorder manifesting as skin and internal organ fibrosis, a diffuse vasculopathy, inflammation, and features of autoimmunity. Patients with diffuse cutaneous disease or internal organ involvement have a poor prognosis with high mortality. To date no therapy has been shown to reverse the natural course of the disease. Immune suppressive drugs are commonly utilized to treat patients, but randomized trials have generally failed to demonstrate any long-term benefit. In phase I/II trials, autologous hematopoietic stem cell transplantation (HSCT) has demonstrated impressive reversal of skin fibrosis, improved functionality and quality of life, and stabilization of internal organ function, but initial studies were complicated by significant treatment-related mortality. Treatment-related mortality was reduced by better pre-transplant evaluation to exclude patients with compromised cardiac function and by treating patients earlier in disease, allowing selected patients the option of autologous HSCT treatment. There are currently three ongoing randomized trials of autologous HSCT for systemic sclerosis: ASSIST (American Systemic Sclerosis Immune Suppression versus Transplant), SCOT (scleroderma cyclophosphamide versus Transplant), and ASTIS (Autologous Stem cell Transplantation International Scleroderma). The results from these trials should clarify the role of autologous HSCT in the currently limited therapeutic arsenal of severe systemic sclerosis.

    There is a lack of prospective and population based epidemiological data on amyotrophic lateral sclerosis in Germany to date. The ALS registry Rhineland-Palatinate was established to investigate the incidence, course and phenotypic variety of ALS in this south-west German state of about 4 million inhabitants. During the period 2010-2011, consecutive incident patients with amyotrophic lateral sclerosis according to the revised El Escorial criteria were included and followed up using multiple overlapping sources of case ascertainment. One hundred and forty-six patients were enrolled. The annual crude incidence for amyotrophic lateral sclerosis in Rhineland-Palatinate was 1.8/100,000 person-years (95% CI 1.6-2.2). Male to female ratio was 1.1:1. Incidence increased with age reaching a peak in the 70-74 years age group and declined thereafter. Late-onset ALS (≥ 75 years) was found in 14.4% of patients. About 32% of patients presented with bulbar onset. In conclusion, incidence rate of amyotrophic lateral sclerosis in Rhineland-Palatinate is within the range of other prospective population based registers in Europe and North America. Gender ratio is nearly balanced.

    Phase images obtained with gradient echo MRI provide image contrast distinct from T1- and T2-weighted images. It is commonly assumed that the local contribution to MRI signal phase directly relates to local bulk tissue magnetic susceptibility. Here, we use Maxwell’s equations and Monte Carlo simulations to provide theoretical background to the hypothesis that the local contribution to MRI signal phase does not depend on tissue bulk magnetic susceptibility but tissue magnetic architecture—distribution of magnetic susceptibility inclusions (lipids, proteins, iron, etc.) at the cellular and subcellular levels. Specifically, we show that the regular longitudinal structures forming cylindrical axons (myelin sheaths and neurofilaments) can be locally invisible in phase images. Contrary to an expectation that the phase contrast in multiple sclerosis lesions should always increase in degree along with worsening of lesion severity (which happens for all known MR magnitude-based contrast mechanisms), we show that phase contrast can actually disappear with extreme tissue destruction. We also show that the phase contrast in multiple sclerosis lesions could be altered without loss of nervous system tissue, which happens in mild injury to the myelin sheaths or axonal neurofilaments. Moreover, we predict that the sign of phase contrast in multiple sclerosis lesions indicates the predominant type of tissue injury—myelin damage (positive sign) vs. axonal neurofilament damage (negative sign). Therefore, our theoretical and experimental results shed light on understanding the relationship between gradient echo MRI signal phase and multiple sclerosis pathology. PMID:22891307

    The current study applies a quantitative, acoustic analysis procedure for the study of rapid syllable productions outlined by Kent and colleagues [R. D. Kent et al., J. Med. Sp. Lang. Path. 7, 83-90 (1999)] to syllables produced by speakers with Parkinson's Disease and Multiple Sclerosis. Neurologically healthy talkers will be studied for comparison purposes. Acoustic measures will be reported for syllable repetitions of /p schwa/, /t schwa/, and /k schwa/. Temporal measures will include syllable duration, syllable rate, and stop gap duration. The energy envelope of syllable repetitions will be quantified using measures of rms amplitude minima and maxima. Acoustic measures will be contrasted to determine the extent to which acoustic profiles of diadochokinesis distinguish hypokinetic dysarthria associated with Parkinson's Disease, ataxic dysarthria secondary to Multiple Sclerosis, and spastic dysarthria secondary to Multiple Sclerosis. It also is of interest to determine whether speakers with Parkinson's Disease and Multiple Sclerosis judged to be nondysarthric via perceptual analyses also demonstrate objective, acoustic profiles of diadochokinesis that are within normal limits.

    Oesophageal dysmotility and abnormalities of intestinal function are important manifestations in systemic sclerosis and may have a significant effect on nutrient absorption and nutritional status. In this study 30 patients with systemic sclerosis with symptoms from the gastrointestinal tract were compared with matched healthy control subjects with respect to nutrient intake (four day record), anthropometric measurements, and biochemical nutritional status. The intake of energy (8.1 and 8.4 MJ/day) and its distribution among nutrients did not differ between patients and control subjects, but the lower intake of dietary fibre among patients with systemic sclerosis suggests that they avoided food with a coarse structure, such as coarse bread. The intake of vegetables and fruit also tended to be lower among patients with systemic sclerosis. Half of the patients had a subnormal arm muscle circumference, and two patients also had a subnormal triceps skinfold thickness, indicating severe malnutrition. The concentration of ascorbic acid, alpha-tocopherol, carotene, selenium, and also the proportion of linoleic acid (18:2) in serum phosphatidylcholine was lower in patients than in control subjects.

    Multiple sclerosis (MS) is a neurological disease that may result in the progressive worsening of disability. Recent research has identified physical activity as a behavioral correlate of disability in MS. The current review highlights that previous research has generally included samples with minimal disability and provides a rationale for considering physical activity as an influence of disability in the second stage of MS.

    In order to relate human auditory processing to physiological and anatomical experimental animal data, we have examined the interrelationships between behavioral, electrophysiological and anatomical data obtained from human subjects with focal brainstem lesions. Thirty-eight subjects with multiple sclerosis were studied with tests of interaural time and level discrimination (just noticeable differences or jnds), brainstem auditory evoked potentials and magnetic resonance (MR) imaging. Interaural testing used two types of stimuli, high-pass (> 4000 Hz) and low-pass (< 1000 Hz) noise bursts. Abnormal time jnds (Tjnd) were far more common than abnormal level jnds (70% vs 11%); especially for the high-pass (Hp) noise (70% abnormal vs 40% abnormal for low-pass (Lp) noise). The HpTjnd could be abnormal with no other abnormalities; however, whenever the BAEPs, LpTjnd and/or level jnds were abnormal HpTjnd was always abnormal. Abnormal wave III amplitude was associated with abnormalities in both time jnds, but abnormal wave III latency with only abnormal HpTjnds. Abnormal wave V amplitude, when unilateral, was associated with a major HpTjnd abnormality, and, when bilateral, with both HpTjnd and LpTjnd major abnormalities. Sixteen of the subjects had their MR scans obtained with a uniform protocol and could be analyzed with objective criteria. In all four subjects with lesions involving the pontine auditory pathway, the BAEPs and both time jnds were abnormal. Of the twelve subjects with no lesions involving the pontine auditory pathway, all had normal BAEPs and level jnds, ten had normal LpTjnds, but only five had normal HpTjnds. We conclude that interaural time discrimination is closely related to the BAEPs and is dependent upon the stimulus spectrum. Redundant encoding of low-frequency sounds in the discharge patterns of auditory neurons, may explain why the HpTjnd is a better indicator of neural desynchrony than the LpTjnd.

    Prevention of irreversible disability is currently the most important goal of disease modifying therapy for multiple sclerosis. The disability outcomes used in most clinical trials rely on progression of Expanded Disability Status Scale score confirmed over 3 or 6 months. However, sensitivity and stability of this metric has not been extensively evaluated. Using the global MSBase cohort study, we evaluated 48 criteria of disability progression, testing three definitions of baseline disability, two definitions of progression magnitude, two definitions of long-term irreversibility and four definitions of event confirmation period. The study outcomes comprised the rates of detected progression events per 10 years and the proportions of the recorded events persistent at later time points. To evaluate the ratio of progression frequency and stability for each criterion, we calculated the proportion of events persistent over the five subsequent years once progression was achieved. Finally, we evaluated the clinical and demographic determinants characterising progression events and, for those that regressed back to baseline, determinants of their subsequent regression. The study population consisted of 16 636 patients with the minimum of three recorded disability scores, totalling 112 584 patient-years. The progression rates varied between 0.41 and 1.14 events per 10 years, with the length of required confirmation interval as the most important determinant of the observed variance. The concordance among all tested progression criteria was only 17.3%. Regression of disability occurred in 11-34% of the progression events over the five subsequent years. The most important determinant of progression stability was the length of the confirmation period. For the most accurate set of the progression criteria, the proportions of 3-, 6-, 12- or 24-month confirmed events persistent over 5 years reached 70%, 74%, 80% and 89%, respectively. Regression post progression was more common

    We have performed a retrospective review of the use of a percutaneous gastrojejunostomy in patients with amyotrophic lateral sclerosis (ALS). Forty-one patients with initial bulbar manifestations of ALS and 32 patients with initial limb manifestations underwent a percutaneous gastrojejunostomy under fluoroscopic control using the Rankin gastrojejunostomy tube. Survival characteristics were compared with 86 bulbar onsetting and 207 limb onsetting ALS patients who did not require nutritional support. The 30-day mortality rate was 9.6% (respiratory death in three bulbar onsetting patients and four limb onsetting patients) and the 30 day morbidity rate was 4.1% (one operative site infection and intraperitoneal leakage in two patients). The most frequent long-term complication was the requirement for tube changing (blockage in six; dislodgment in two). Gastric reflux was not described amongst the treated patients. Overall survivorship (symptom onset to death) was less in the bulbar onsetting patients receiving a gastrojejunostomy tube than in the control population (median survival 22.0 vs. 33.7 months, respectively, P=0.005). As a group, the median survivorship for limb onsetting patients was not different for those receiving a gastrojejunostomy than for those who did not. However, a significant reduction in survival was observed in limb onsetting patients receiving a gastrojejunostomy early in the course of their disease (P=0.001) compared to those with a longer duration prior to the procedure. This was not observed in the bulbar onsetting patients. In both patient populations, no relationship was observed between survival post-gastrojejunostomy and the severity of pulmonary involvement at the time of the intervention, serum chloride, or age at onset. These studies demonstrate that a percutaneous gastrojejunostomy is a well-tolerated and safe alternative technique for enteral nutritional support in ALS patients. It also offers the advantage of not requiring either a

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

    The majority of individuals obtaining the diagnosis of multiple sclerosis are women of childbearing age. They are naturally concerned as to how multiple sclerosis affects the course of pregnancy and the developing foetus. The objective of this study was to prospectively evaluate the incidence of pregnancy complications and delivery risks, and to follow the natural course of multiple sclerosis during and after pregnancy in a cohort of Finnish patients with multiple sclerosis. Sixty-one patients with multiple sclerosis who became pregnant during the years 2003-2005 were prospectively followed-up from early pregnancy until 6 months postpartum. Multiple sclerosis relapses, Expanded Disability Status Scale rates and obstetric details were recorded. The results were compared with the statistics obtained from Finnish Medical Birth Register from the year 2004. We found that patients with multiple sclerosis were no more likely to experience pregnancy complications than Finnish pregnant women generally, but they had a greater likelihood for a need of artificial insemination (4.9% vs. 0.9%; p = 0.0009). Subjects with multiple sclerosis were more likely to undergo assisted vaginal delivery than the at-large cohort (16.4% vs. 6.5%; p = 0.0017). We conclude that pregnancy does not seem to pose a woman with multiple sclerosis to a greater risk for pregnancy complications when compared with women in general. The potential need for instrumental delivery should, however, be taken into account when planning the delivery of a mother with multiple sclerosis.

    Preventing chronic disease deterioration is an unmet need in people with multiple sclerosis, where axonal loss is considered a key substrate of disability. Clinically, chronic multiple sclerosis often presents as progressive myelopathy. Spinal cord cross-sectional area assessed using MRI predicts increasing disability and has, by inference, been proposed as an indirect index of axonal degeneration. However, the association between cross-sectional area and axonal loss, and their correlation with demyelination, have never been systematically investigated using human post mortem tissue. We extensively sampled spinal cords of seven women and six men with multiple sclerosis (mean disease duration= 29 years) and five healthy controls to quantify axonal density and its association with demyelination and cross-sectional area. 396 tissue blocks were embedded in paraffin and immuno-stained for myelin basic protein and phosphorylated neurofilaments. Measurements included total cross-sectional area, areas of (i) lateral cortico-spinal tracts, (ii) grey matter, (iii) white matter, (iv) demyelination, and the number of axons within the lateral cortico-spinal tracts. Linear mixed models were used to analyse relationships. In multiple sclerosis cross-sectional area reduction at cervical, thoracic and lumbar levels ranged between 19 and 24% with white (19-24%) and grey (17-21%) matter atrophy contributing equally across levels. Axonal density in multiple sclerosis was lower by 57-62% across all levels and affected all fibres regardless of diameter. Demyelination affected 24-48% of the grey matter, most extensively at the thoracic level, and 11-13% of the white matter, with no significant differences across levels. Disease duration was associated with reduced axonal density, however not with any area index. Significant association was detected between focal demyelination and decreased axonal density. In conclusion, over nearly 30 years multiple sclerosis reduces axonal density by 60

    Drug development for multiple sclerosis (MS), as with any other neurological disease, faces numerous challenges, with many drugs failing at various stages of development. The disease-modifying therapies (DMTs) first introduced for MS are only moderately effective, but given the lack of competition, they have been widely accepted in clinical practice. Although safety and efficacy continue to be the two main metrics by which drugs will be judged, the newer agents in the market also face challenges of a more comparative nature-are they more efficacious than the currently available drugs on the market? Are they safer or better tolerated? Do they offer any practical advantages over current treatments? Fingolimod represented a milestone following its approval as an oral drug for MS in 2010, offering patients a far more convenient administration route. However, association with cardiovascular complications has led to a more cautious approach in its initial prescribing, now requiring cardiac monitoring for the first 6 h as well as subsequent monitoring of blood pressure and for macular oedema. Natalizumab, amongst licensed drugs, represents the current benchmark for efficacy. The risk of progressive multifocal leukoencephalopathy during natalizumab treatment is now more quantifiable. Other monoclonal antibodies are in various phases of development. Marketing authorisation for alemtuzumab has been filed, and whilst trial data suggest that its efficacy outperforms both licensed drugs and others in development, there is a significant risk of secondary autoimmunity. Its once-yearly administration, however, seems particularly advantageous. Rituximab is unlikely to be developed further as its license will expire, but ocrelizumab, another monoclonal antibody directly targeting B cells, is currently in phase 2 development and looks promising. Daclizumab is also moderately efficacious but may struggle to establish itself given its monthly subcutaneous dosing. There are new oral

    Multiple sclerosis (MS) is an inflammatory demyelinating disease of the CNS, characterized pathologically by a perivascular infiltrate consisting predominantly of T cells and macrophages. Although its aetiology remains unknown, several lines of evidence support the hypothesis that autoimmune mechanisms play a major role in the development of the disease. Several widely used disease-modifying agents are approved for the treatment of MS. However, these agents are only partially effective and their ability to attenuate the more progressive phases of the disease is not clear at this time. Therefore, there is a need to develop improved treatment options for MS. This article reviews the role of several novel, selective vaccine strategies that are currently under investigation, including: (i) T-cell vaccination (TCV); (ii) T-cell receptor (TCR) peptide vaccination; (iii) DNA vaccination; and (iv) altered peptide ligand (APL) vaccination. The administration of attenuated autoreactive T cells induces regulatory networks to specifically suppress pathogenic T cells in MS, a strategy named TCV. The concept of TCV was based on the experience of vaccination against aetiological agents of infectious diseases in which individuals are purposely exposed to an attenuated microbial pathogen, which then instructs the immune system to recognize and neutralize it in its virulent form. In regard to TCV, attenuated, pathogenic T cells are similarly used to instruct the immune system to recognize and neutralize disease-inducing T cells. In experimental allergic encephalomyelitis (EAE), an animal model for MS, pathogenic T cells use a strikingly limited number of variable-region elements (V region) to form TCR specific for defined autoantigens. Thus, vaccination with peptides directed against these TCR structures may induce immunoregulatory mechanisms, thereby preventing EAE. However, unlike EAE, myelin-reactive T cells derived from MS patients utilize a broad range of different V regions

    2017-03-10

    Dopamine is a key neurotransmitter that induces critical effects in the nervous system and in many peripheral organs, via 5 dopamine receptors (DRs): D1R-D5R. Dopamine also induces many direct and very potent effects on many DR-expressing immune cells, primarily T cells and dendritic cells. In this review, we focus only on dopamine receptors, effects and production in T cells. Dopamine by itself (at an optimal concentration of~0.1 nM) induces multiple function of resting normal human T cells, among them: T cell adhesion, chemotactic migration, homing, cytokine secretion and others. Interestingly, dopamine activates resting effector T cells (Teffs), but suppresses regulatory T cells (Tregs), and both effects lead eventually to Teff activation. Dopamine-induced effects on T cells are dynamic, context-sensitive and determined by the: T cell activation state, T cell type, DR type, and dopamine concentration. Dopamine itself, and also few dopaminergic molecules/ drugs that are in clinical use for cardiac, neurological and other non-immune indications, have direct effects on human T cells (summarized in this review). These dopaminergic drugs include: dopamine = intropin, L-DOPA, bromocriptine, pramipexole, pergolide, haloperidol, pimozide, and amantadine. Other dopaminergic drugs were not yet tested for their direct effects on T cells. Extensive evidence in multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE) show dopaminergic dysregulations in T cells in these diseases: D1-like DRs are decreased in Teffs of MS patients, and dopamine does not affect these cells. In contrast, D1-like DRs are increased in Tregs of MS patients, possibly causing functional Treg impairment in MS. Treatment of MS patients with interferon β (IFN-β) increases D1-like DRs and decreases D2-like DRs in Teffs, decreases D1-like DRs in Tregs, and most important: restores responsiveness of patient's Teffs to dopamine. DR agonists and antagonists confer some benefits in

We describe a 41-year-old man who developed systemic sclerosis after working for 15 years in a foundry, where he had extensive cutaneous contact with multiple organic solvents (trichloroethane, xylene, trimethylbenzene, and naphthalene). Cutaneous exposure to organic solvents may be a factor in the etiology of some cases of systemic sclerosis.15 references.

    It is estimated that early-onset multiple sclerosis multiple sclerosis (early-onset multiple sclerosis) approximately incorporates 3-5% of the multiple sclerosis population. In this report on early-onset multiple sclerosis, the authors aimed to define demographic, clinical and imaging features in a case-series of true-childhood multiple sclerosis and to compare its characteristics with juvenile multiple sclerosis. The authors inspected the records of multiple sclerosis patients who were registered by Isfahan MS Society. Clinical and demographic data of children with less than 16 years of age were reviewed retrospectively. Out of 4536 multiple sclerosis patients referred to the authors' center, 221 patients (4.8%) had multiple sclerosis starting at the age of 16 or less (11 true-childhood multiple sclerosis vs 210 juvenile-onset multiple sclerosis); the female to male ratio was 4.81:1. In the mean follow-up period of 6.2 years, 22 patients (10.5%) had positive family history of multiple sclerosis, 196 (88.6%) patients were classified as relapsing-remitting multiple sclerosis, the mean (± SD Expanded Disability Status Scale) was 1.5 ± 1.1 at the last evaluation. The most common initial presentation was optic nerve involvement (36.1%) and cerebellar sign and symptoms (14.6%). In all, 13 patients (5.8%) had experienced seizure in the course of multiple sclerosis. This study indicated that early-onset multiple sclerosis is not rare condition and overwhelmingly affects girls even at prepubertal onset.

    It has been suggested that exercise (or physical activity) might have the potential to have an impact on multiple sclerosis (MS) pathology and thereby slow down the disease process in MS patients. The objective of this literature review was to identify the literature linking physical exercise (or activity) and MS disease progression. A systematic literature search was conducted in the following databases: PubMed, SweMed+, Embase, Cochrane Library, PEDro, SPORTDiscus and ISI Web of Science. Different methodological approaches to the problem have been applied including (1) longitudinal exercise studies evaluating the effects on clinical outcome measures, (2) cross-sectional studies evaluating the relationship between fitness status and MRI findings, (3) cross-sectional and longitudinal studies evaluating the relationship between exercise/physical activity and disability/relapse rate and, finally, (4) longitudinal exercise studies applying the experimental autoimmune encephalomyelitis (EAE) animal model of MS. Data from intervention studies evaluating disease progression by clinical measures (1) do not support a disease-modifying effect of exercise; however, MRI data (2), patient-reported data (3) and data from the EAE model (4) indicate a possible disease-modifying effect of exercise, but the strength of the evidence limits definite conclusions. It was concluded that some evidence supports the possibility of a disease-modifying potential of exercise (or physical activity) in MS patients, but future studies using better methodologies are needed to confirm this.

    Trigeminal root entry zone abnormality on brain magnetic resonance imaging has been frequently reported in multiple sclerosis patients, but it has not been investigated in neuromyelitis optica patients. Brain magnetic resonance imaging of 128 consecutive multiple sclerosis patients and 46 neuromyelitis optica patients was evaluated. Trigeminal root entry zone abnormality was present in 11 (8.6%) of the multiple sclerosis patients and two (4.3%) of the neuromyelitis optica patients. The pontine trigeminal root entry zone may be involved in both multiple sclerosis and neuromyelitis optica.

    Induced plant defenses against herbivores are modulated by jasmonic acid-, salicylic acid-, and ethylene-signaling pathways. Although there is evidence that some pathogens suppress plant defenses by interfering with the crosstalk between different signaling pathways, such evidence is scarce for herbivores. Here, we demonstrate that the mealybug Phenacoccus solenopsis suppresses the induced defenses in tomato. We found that exogenous JA, but not SA, significantly decreased mealybug feeding time and reduced nymphal performance. In addition, constitutive activation of JA signaling in 35s::prosys plants reduced mealybug survival. These data indicate that the JA signaling pathway plays a key role in mediating the defense responses against P. solenopsis. We also found that mealybug feeding decreased JA production and JA-dependent defense gene expression, but increased SA accumulation and SA-dependent gene expression. In SA-deficient plants, mealybug feeding did not suppress but activated JA accumulation, indicating that the suppression of JA-regulated defenses depends on the SA signaling pathway. Mealybugs benefit from suppression of JA-regulated defenses by exhibiting enhanced nymphal performance. These findings confirm that P. solenopsis manipulates plants for its own benefits by modulating the JA-SA crosstalk and thereby suppressing induced defenses. PMID:25790868

    Jasmonates are phytohormones involved in a wide range of plant processes, including growth, development, senescence, and defense. Jasmonoyl-L-isoleucine (JA-Ile, 2), an amino acid conjugate of jasmonic acid (JA, 1), has been identified as a bioactive endogenous jasmonate. However, JA-Ile (2) analogues trigger different responses in the plant. ω-Hydroxylation of the pentenyl side chain leads to the inactive 12-OH-JA-Ile (3) acting as a “stop” signal. On the other hand, a lactone derivative of 12-OH-JA (5) (jasmine ketolactone, JKL) occurs in nature, although with no known biological function. Inspired by the chemical structure of JKL (6) and in order to further explore the potential biological activities of 12-modified JA-Ile derivatives, we synthesized two macrolactones (JA-Ile-lactones (4a) and (4b)) derived from 12-OH-JA-Ile (3). The biological activity of (4a) and (4b) was tested for their ability to elicit nicotine production, a well-known jasmonate dependent secondary metabolite. Both macrolactones showed strong biological activity, inducing nicotine accumulation to a similar extent as methyl jasmonate does in Nicotiana attenuata leaves. Surprisingly, the highest nicotine contents were found in plants treated with the JA-Ile-lactone (4b), which has (3S,7S) configuration at the cyclopentanone not known from natural jasmonates. Macrolactone (4a) is a valuable standard to explore for its occurrence in nature.

    Progressive systemic sclerosis is a chronic sclerotic disease which causes diffuse, increased deposition of extracellular matrix in connective tissue with vascular abnormalities, resulting in tissue hypoxia. Aesthetic and facial dysfunction are followed by important oral and facial manifestation of disturbances such as xerostomia, the lack of saliva in the mouth, and its associated complications. Most clinical manifestations begin with tongue rigidity. The facial skin changes and bone resorption of mandible angle are often reported. Other systemic changes include the involvement of internal organs which leads to serious complications as well as disorders in the cardiac muscle and Raynaud's phenomenon. The objective of the this paper is to report two cases of systemic sclerosis in patients with oral and facial manifestations of the disease. A brief review of the literature, focusing on deontological alterations is also presented.

    An estimate of the prevalence of autism in tuberous sclerosis (TSC) was made by interviewing the parents of 21 children between ages 3 and 11 ascertained during a previous population study of the condition in the West of Scotland. Five of the children (24%) were rated autistic and a further four (19%), all of whom were girls, had socially impaired behavior categorized as pervasive developmental disorder, without fulfilling all the DSM-III-R criteria for autism. One further boy had disruptive attention-seeking behavior that had excluded him from his normal school. The estimated prevalence from this study of autism in TSC is 1 in 4 children in general, and 1 in 2 of those with mental retardation. Tuberous sclerosis could be a significant cause of autism and pervasive developmental disorders, particularly in girls.

    Gastric and esophageal emptying were assessed using scintigraphic techniques in 12 patients with progressive systemic sclerosis and 22 normal volunteers. Esophageal emptying was significantly delayed in the patient group, with 7 of the 12 patients beyond the normal range. Gastric emptying was slower in patients than in controls, with 9 patients being outside the normal range for solid emptying and 7 patients outside the normal range for liquid emptying. Findings from gastric and esophageal emptying tests generally correlated well with symptoms of dysphagia and gastroesophageal reflux. However, 2 patients with normal emptying studies had symptomatic heartburn, and 2 patients with delay of both solid and liquid gastric emptying gave no history of gastroesophageal reflux. Delayed gastric emptying may be an important factor in the development of upper gastrointestinal symptoms in patients with progressive systemic sclerosis.

    Amyotrophic lateral sclerosis is a rare disease. It is a fatal neurodegenerative disease characterized by progressive muscular paralysis reflecting degeneration of motor neurons which leads to muscle weakness and muscle wasting. Respiratory failure limits survival to 2-5 years after disease onset. Several clinical manifestations including dysphagia can result in reductions in both the quality of life and life expectancy. Dysphagia occurs at onset in about one third of case, although generally it occurs in later stage of the disease. Evaluation of dysphagia includes video-fluoroscopic swallow study, radiological esophagogram, flexible endoscopic examination, ultrasound examination, conventional manometry and electromyography. We report a case of amyotrophic lateral sclerosis in a 54-year-old man presenting oropharyngeal dysphagia which was diagnosed by high resolution esophageal manometry presenting abnormality of the upper esophageal sphincter.

    Multiple Sclerosis is a multifactorial disease with several pathogenic mechanisms and pathways. Successful MS management and medical care requires early accurate diagnosis along with specific treatment protocols based upon multifunctional nanotechnology approach. This paper highlights advances in nanotechnology that have enabled the clinician to target the brain and CNS in patient with multiple sclerosis with nanoparticles having therapeutic and imaging components. The multipartite theranostic (thera(py) + (diag)nostics) approach puts forth strong implications for medical care and cure in MS. The current nanotheranostics utilize tamed drug vehicles and contain cargo, targeting ligands, and imaging labels for delivery to specific tissues, cells, or subcellular components. A brief overview of nonsurgical nanorepair advances as future perspective is also described. Considering the potential inflammatory triggers in MS pathogenesis, a multifunctional nanotechnology approach will be needed for the prognosis. PMID:23346386

    Multiple sclerosis is a major demyelinating disease of the central nervous system. It has a significant economic and social impact. Its etiology is unclear, although there are several hypotheses, such as infections or genetics. In its pathophysiology, it seems that immune activation attacks the myelin sheath, causing a progressive and irreversible axonal degeneration. The disease produces a variety of symptoms, and diagnosis requires fulfilling a number of criteria and the exclusion of other possible causes. The role of neuroimaging is very important, especially Magnetic Resonance Imaging. Despite the availability of disease-modifying drugs, none of them are able to halt its progress, and the most useful drugs are those designed to alleviate the symptoms of outbreaks. Overall, multiple sclerosis requires a significant effort in research to clarify not only why and how it occurs, as well as the development of new measures to improve quality of life of affected patients.

  15. Therapy Insight: bladder dysfunction associated with multiple sclerosis.

    2005-10-01

    Bladder dysfunction is a common problem for patients with multiple sclerosis. The severity of symptoms often correlate with the degree of spinal cord involvement and, hence, the patient's general level of disability. The emphasis of management is now mainly medical and is increasingly offered by nonurologists. Treatments can be highly effective, relieving patients of what are otherwise very troublesome symptoms that would compound their neurological disability. This article gives an overview of the neural control of the bladder, followed by an explanation of the pathophysiology of detrusor overactivity secondary to neurological disease. A review of methods available for treating bladder dysfunction in multiple sclerosis then follows. The treatment options for this disorder are largely medical and include established first-line measures such as anticholinergics, clean intermittent self-catheterization and the use of desmopressin, as well as potential second-line agents, such as cannabinoids, intravesical vanilloids and intradetrusor botulinum neurotoxin type A. The diminishing role of surgical intervention is also discussed.

    Intra-thoracic manifestations of progressive systemic sclerosis (PSS) are not well known particularly the imaging features, which forms the basis of accurate and timely diagnosis. The aim of this study is to familiarize the physicians and radiologists with these features. The diagnosis can remain elusive because of the non-specific nature of symptoms which mimic many common conditions. Thus, the diagnosis of PSS can be missed leading to continuous morbidity if the correct imaging is not pursued. The authors examined the records of rheumatology patient referrals of over a 5 year period. A hundred and seventy patients with systemic sclerosis and mixed connective tissue disorders were chosen for detailed study of the imaging available, which form the basis of this review. The images included conventional chest radiographs, digital radiographs computed radiography (CT) and high resolution computed tomography (HRCT). Where applicable computed pulmonary angiography (CTPA) and radionuclide scans were also interrogated.

    Fibrosis is recognized as an important feature of many chronic diseases, such as systemic sclerosis (SSc), an autoimmune disease of unknown etiology, characterized by immune dysregulation and vascular injury, followed by progressive fibrosis affecting the skin and multiple internal organs. SSc has a poor prognosis because no therapy has been shown to reverse or arrest the progression of fibrosis, representing a major unmet medical need. Recently, antifibrotic effects of PPARγ ligands have been studied in vitro and in vivo and some theories have emerged leading to new insights. Aberrant PPARγ function seems to be implicated in pathological fibrosis in the skin and lungs. This antifibrotic effect is mainly related to the inhibition of TGF-β/Smad signal transduction but other pathways can be involved. This review focused on recent studies that identified PPARγ as an important novel pathway with critical roles in regulating connective tissue homeostasis, with emphasis on skin and lung fibrosis and its role on systemic sclerosis.

    1994-10-01

    To understand the relationship between brainstem lesions and auditory neurology in patients with multiple sclerosis, we compared behavioural, electrophysiological and imaging data in 38 patients with probable or definite multiple sclerosis and normal or near normal hearing. Behavioural measures included (i) general hearing tests (audiogram, speech discrimination) and (ii) hearing tests likely to be critically dependent upon brainstem processing (masking level difference, interaural time and level discrimination). Brainstem auditory evoked potentials provided the electrophysiological data. Multiplanar high-resolution MRI of the brainstem provided the anatomical data. Interaural time discrimination for high-frequency sounds was by far the most sensitive of all tests with abnormalities in 71% of all subjects. Whenever any other test was abnormal this test was always abnormal. Interaural time discrimination for low-frequency sounds and evoked potentials were closely related and next most sensitive with abnormalities in approximately 40% of all subjects. Interaural level discrimination and masking level difference were least sensitive with abnormalities in < 10% of subjects. Speech discrimination scores correlated significantly with the masking level differences, as well as with interaural time discrimination for high-frequency sounds. Pontine lesions were found in five of the 16 patients, in whom an objective method for detecting magnetic resonance lesions could be applied. All four with lesions involving the pontine auditory pathway had marked abnormalities in interaural time discrimination and evoked potentials. None of the other 12 had evoked potentials abnormalities. We conclude that neurological tests requiring precise neural timing can reveal behavioural deficits for multiple sclerosis lesions of the auditory pons that are otherwise 'silent'. Of all neurological systems the auditory system at the level of the pons is probably the most sensitive to multiple

    Multiple Sclerosis (MS) is a chronic and disabling disease with a considerable social impact and economic consequences. In Europe, it is the most common cause of non-traumatic disability in young adults. Existing therapies that target immune modulation are largely ineffective in halting the progression of the disease and are fraught with severe side effects. Therefore, managing the comorbidities of MS is of utmost importance for long-term patient care and quality of life.

    To investigate the occurrence of vascular comorbidities before and after the clinical onset of multiple sclerosis. In this combined case-control and cohort study, all Danish born citizens with onset of multiple sclerosis 1980-2005 were identified from the Danish Multiple Sclerosis Registry and randomly matched with controls regarding year of birth, gender, and municipality on January 1st in the year of multiple sclerosis (MS) onset (index date). Individual-level information on comorbidities was obtained from several independent nationwide registries and linked to the study population by unique personal identification numbers. To assess the presence of vascular comorbidities before and after MS onset, cases and controls were followed from January 1977 to the index date, and from the index date through December 2012. We used logistic regression to calculate odds ratios (ORs) and Cox regression to calculate hazard ratios (HRs). Before the index date, MS cases had a decreased probability for cerebrovascular comorbidity [OR 0.69 (95 % CI 0.48-0.99, p = 0.043)], and a numerically but not statistically significant decreased probability for cardiovascular comorbidity [OR 0.87 (95 % CI 0.71-1.07, p = 0.188)]. After the index date, MS cases had an increased risk for cerebrovascular comorbidity [HR 1.84 (95 % CI 1.69-2.00, p < 0.0005)], and for cardiovascular comorbidity [HR 1.08 (95 % CI 1.02-1.15, p = 0.013)]. The lower occurrence of cerebrovascular comorbidities in cases prior to MS onset could be due to protective immune mechanisms, while the higher occurrence of vascular comorbidities in cases after MS onset could be because of converging causal pathways of the coexisting diseases. These findings deserve to be studied closer in a broader spectrum of comorbidities in MS.

    Abnormalities of swallowing are commonly encountered in Multiple Sclerosis (MS), especially in the most disabled patients. The disturbances usually involve oral and pharyngeal phases of swallowing, although upper oesophageal sphincter dysfunction has also been detected. MS patients need to be effectively evaluated and managed in order to recognize dysphagia before any medical complications such as aspiration pneumonia appear. An integrated approach is proposed to define the severity of dysphagia and to devise the most appropriate therapeutic/rehabilitative methodology.

    We describe a case with simultaneous occurrence of cluster headache-like pain and multiple sclerosis. Both neuroimaging and neurophysiology (trigeminal evoked potentials) revealed a demyelination plaque in the pons, at the trigeminal root entry zone, on the side of pain. Although that type of lesion is usually associated with trigeminal neuralgia pain, we hypothesize that in this case it may be linked with the concomitant cluster headache, possibly by activation of trigemino-vascular mechanisms.

  11. Role of statins in the treatment of multiple sclerosis.

    2014-09-01

    Statins as inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase are widely prescribed for hypercholesterolemia treatment. In the last years, statins have also been shown to exert immunomodulatory and anti-inflammatory effects which appear to be related to inhibition of isoprenylation of small GTP-binding proteins and, at least in part, independent of their cholesterol-lowering effects. These "pleiotropic" effects make statins an attractive treatment option for immune-mediated disorders such as multiple sclerosis. Studies in vitro and in experimental autoimmune encephalomyelitis animal model seem to support not only the efficacy of statins as immunomodulatory agents but also their potential neuroprotective properties, although the exact mechanism with which statins exert these effects has not yet been fully understood. The immunomodulatory, anti-inflammatory and neuroprotective properties of statins provided the incentive for several clinical trials in multiple sclerosis, in which they were tested not only as mono-therapy but also in combination with interferon-β. However, the attempt to translate the results of animal model studies in humans produced conflicting results. Further large, prospective, randomized, double-blind, placebo-controlled trials, designed to evaluate the long-term effects of statins alone or in add-on to other disease-modifying therapies, are needed to support their routine clinical use in multiple sclerosis.

    Objective: To determine the oral treatment needs of a sample of patients diagnosed with multiple sclerosis in the Community of Madrid (Spain). Patients and methods: A cross-sectional epidemiological study was carried out with a sample of 64 patients who were aged 25 to 77 years. They were distributed into homogeneous age groups: < 46 years, 46-54 years and > 54 years. In order to evaluate the oral health status and treatment requirements, the parameters and guidelines of the WHO were used. Results: The prevalence of caries was 100%, or very close in all three groups. As age increased, the morbidity rate decreased, but the mortality rate increased considerably. On analyzing gingival health, 65% of patients had calculus, 5% bleeding and 30% were healthy. Conclusions: The DMFT index found provided data that was, in general, very similar to that of the general population in Spain. However, the gingival health status found demonstrated that the population of multiple sclerosis patients requires specific assistance. Key words: Multiple sclerosis, oral health, dentures.

  15. Histopathological cutaneous alterations in systemic sclerosis: a clinicopathological study

    PubMed Central

    2011-01-01

    Introduction The aims of the present study were to identify histopathological parameters which are linked to local clinical skin disease at two distinct anatomical sites in systemic sclerosis (SSc) patients with skin involvement (limited cutaneous systemic sclerosis (lcSSc) or diffuse cutaneous systemic sclerosis (dcSSc)) and to determine the sensitivity of SSc specific histological alterations, focusing on SSc patients without clinical skin involvement (limited SSc (lSSc)). Methods Histopathological alterations were systematically scored in skin biopsies of 53 consecutive SSc patients (dorsal forearm and upper inner arm) and 18 controls (upper inner arm). Clinical skin involvement was evaluated using the modified Rodnan skin score. In patients with lcSSc or dcSSc, associations of histopathological parameters with local clinical skin involvement were determined by generalised estimation equation modelling. Results The hyalinised collagen score, the myofibroblast score, the mean epidermal thickness, the mononuclear cellular infiltration and the frequency of focal exocytosis differed significantly between biopsies with and without local clinical skin involvement. Except for mononuclear cellular infiltration, all of the continuous parameters correlated with the local clinical skin score at the dorsal forearm. Parakeratosis, myofibroblasts and intima proliferation were present in a minority of the SSc biopsies, but not in controls. No differences were found between lSSc and controls. Conclusions Several histopathological parameters are linked to local clinical skin disease. SSc-specific histological alterations have a low diagnostic sensitivity. PMID:21356083

    The aim of the study is to determine the association between respiratory swallow patterns in amyotrophic lateral sclerosis (ALS) patients. Furthermore, it aims to clarify the role of the dysphagia limit in defining the relationship between swallowing disorders and respiratory disorders. Functional rating scales were used to describe swallowing and respiratory function. Swallowing was observed using the dysphagia limit. Dysphagia limit is the volume at which a second or more swallows are required to swallow the whole bolus. Laryngeal and chest movement sensors, pulmonary function tests, submental, and diaphragm electromyography activity were used to evaluate the relationship between swallowing and respiratory phase. Of the 27 patients included in the study, 14 were dysphagic and 13 were non-dysphagic. Tests showed normal respiratory function in 11 of the non-dysphagic patients and 3 of the dysphagic patients. There was a high correlation between the dysphagia limit and Amyotrophic Lateral Sclerosis Functional Rating Scale swallowing parameters. Non-dysphagic patients were able to swallow during inspiration but only six patients in the dysphagic group were able to swallow during inspiration. The occurrence of dysphagia in ALS is related to piecemeal deglutition and respiration consistency during swallowing. Detecting the timing of disturbances in the relationship between swallowing and respiration may be a way of identifying dysphagia. Dysphagia limit may be a useful, complementary test for assessing swallowing disturbances in amyotrophic lateral sclerosis.

    2015-09-01

    Compartment syndrome refers to a condition of compromised circulation within a limited space due to increased pressure within that space. The reduced tissue perfusion results in reduced venous drainage, leading to increased interstitial tissue pressure and subsequent compromised arterial flow. Although not as common as compartment syndrome of the leg and forearm, compartment syndrome of the hand is not rare and can lead to devastating sequelae as a result of tissue necrosis. Compartment syndrome of the hand has several etiologies, including trauma, arterial injury, thermal injury, and constrictive bandaging. The cardinal clinical sign is pain that is aggravated by passive stretching of the muscles within the involved compartments. Extremity function is usually restored with expeditious fasciotomy of the involved myofascial compartments, and complications, such as intrinsic muscular dysfunction and Volkmann's ischemic contracture, can usually be prevented. There are no reported cases of compartment syndrome of the hand in patients with systemic sclerosis or Raynaud's phenomenon. Systemic sclerosis is a form of scleroderma that affects the skin and internal organs. The limited cutaneous subset affects the skin of the extremities but is associated with a set of characteristic features that includes calcinosis, Raynaud's phenomenon, esophageal involvement, sclerodactyly, and telangiectasia. This report describes an unusual case of a patient who had spontaneous compartment syndrome of the hand. The patient's concomitant limited cutaneous systemic sclerosis may have played a role in this unusual occurrence. The diagnosis was based on the clinical picture, and the symptoms resolved after surgical decompression.

  18. Autobiographical memory in multiple sclerosis patients: assessment and cognitive facilitation.

    The multifocal nature of lesions in multiple sclerosis hints at the occurrence of autobiographical memory (AbM) impairment. However, the dearth of studies on AbM in multiple sclerosis is noticeable, notwithstanding the importance of AbM in everyday life. In the first section of this study, 25 multiple sclerosis patients and 35 controls underwent a detailed episodic AbM assessment. Results obtained by means of ANOVA suggested an AbM retrieval deficit in every patient. That pattern of performance paved the way for the second section of the study, in which we followed up 10 out of the 25 patients. Our objective was to assess the effectiveness of a cognitive facilitation programme designed to alleviate AbM retrieval deficits, based on the key role of mental visual imagery on AbM. Statistical group analyses by means of ANOVA and individual analyses using the χ(2) test showed significant differences in AbM test results, in post-facilitation relative to pre-facilitation training, in all 10 patients. Moreover, the patients' comments showed that the positive effects were transferred in their daily life functioning. We would like to suggest that the facilitation programme efficiently enhanced the process of self-centred mental visual imagery, which might have compensated for poor retrieval of personal memories by providing better access to visual details and detailed visual scenes of personal recollections.

  19. Limited systemic sclerosis initially presenting with mesenteric panniculitis

    2014-01-01

    Mesenteric panniculitis pertains to a group of uncommon disorders named sclerosing mesenteritis that present with different levels of inflammation and fibrosis of the small bowel mesentery. It is associated with abdominal surgeries, trauma, malignancies, infections and connective tissue diseases. To the best of our knowledge, no cases of sclerosing mesenteritis have been reported in patients with systemic sclerosis. We present a case of a 61-year-old woman who had incidental CT findings of mesenteric panniculitis. Diagnosis was confirmed by biopsy that showed fat necrosis. On further review she had a 1-year history of Raynaud's phenomenon. Physical examination showed sclerodactyly. She had elevated anticentromere antibodies and skin biopsy was consistent with scleroderma. She was diagnosed with limited systemic sclerosis and was treated with D-penicillamine. After 6 years of follow-up, the mesenteric panniculitis and systemic sclerosis both remained stable. This case highlights the importance of considering rheumatic diseases in the differential diagnosis of sclerosing mesenteritis. PMID:25326572

    Objectives. To examine the association between fall history and physical activity using an objective measure of physical activity (i.e., accelerometry) in persons with multiple sclerosis. Design. A community-based sample of 75 ambulatory persons with multiple sclerosis volunteered for the investigation. Participants self-reported fall history in the last year, underwent a neurological exam to determine Expanded Disability Status Scale (EDSS) score, and wore an accelerometer around the waist for 7 consecutive days to determine physical activity. Results. Overall, 37 persons (49.3% of the sample) reported falling in the last year with 28 of the 37 falling more than once. Persons who fell in the last year had a significantly lower number of steps/day than nonfallers (3510 versus 4940 steps/day; P < .05). However, when controlling for disability status there was no statistically significant difference between fallers and nonfallers (4092 versus 4373 steps/day; P > .05). Conclusions. Collectively, the findings suggest that fall history may have little impact on current physical activity levels in persons with multiple sclerosis. PMID:22966459

    Multiple sclerosis is an immune-mediated, demyelinating and neurodegenerative disease that currently lacks any neuroprotective treatments. Innovative neuroprotective trial designs are required to hasten the translational process of drug development. An ideal target to monitor the efficacy of strategies aimed at treating multiple sclerosis is the visual system, which is the most accessible part of the human central nervous system. A novel C57BL/6 mouse line was generated that expressed transgenes for a myelin oligodendrocyte glycoprotein-specific T cell receptor and a retinal ganglion cell restricted-Thy1 promoter-controlled cyan fluorescent protein. This model develops spontaneous or induced optic neuritis, in the absence of paralytic disease normally associated with most rodent autoimmune models of multiple sclerosis. Demyelination and neurodegeneration could be monitored longitudinally in the living animal using electrophysiology, visual sensitivity, confocal scanning laser ophthalmoscopy and optical coherence tomography all of which are relevant to human trials. This model offers many advantages, from a 3Rs, economic and scientific perspective, over classical experimental autoimmune encephalomyelitis models that are associated with substantial suffering of animals. Optic neuritis in this model led to inflammatory damage of axons in the optic nerve and subsequent loss of retinal ganglion cells in the retina. This was inhibited by the systemic administration of a sodium channel blocker (oxcarbazepine) or intraocular treatment with siRNA targeting caspase-2. These novel approaches have relevance to the future treatment of neurodegeneration of MS, which has so far evaded treatment. PMID:24223903

    Introduction Spasticity is one of the most disabling and difficult-to-treat symptoms shown by patients with multiple sclerosis, who often show a suboptimal and unsatisfactory response to classic treatment and new available nonpharmacological alternatives. Due to the progressive nature of this condition, the early management should be essential to improve long-term outcomes. Methods We performed a narrative literature review of the contribution of spasticity to the burden of multiple sclerosis and the potential role of classic disease-modifying drugs. Results Added to the underlying pathophysiology of spasticity, certain external factors and drugs such as interferon may exacerbate the existing condition, hence their awareness is crucial as part of an effective management of spasticity. Furthermore, the evidence for the effectiveness of glatiramer acetate in preventing spasticity in naïve patients and in those switching from interferon should not be ignored. Conclusions This literature review proposes the examination of spasticity and the influence of classic disease-modifying agents on the level of existing condition among the variables to be considered when deciding on therapy for multiple sclerosis in clinical practice.

    An analysis of ten climatic factors and elevation for the counties of birth of 4371 U.S. white male veterans with multiple sclerosis and matched controls has been made in relation to birthplace latitude. The climatic factors include an air pollution index, concentrations of minerals in ground water, measures of annual solar radiation, both in energy per unit area and in hours of sunshine, mean annual periods of high and low temperatures, and measures of annual rainfall and average humidity. These variables all significantly influence the risk of multiple sclerosis when analyzed alone, but when they are adjusted for latitude, their effect is found to be due to their correlation with this variable.

    The main objective of our work is to describe the long-term results of myeloablative autologous hematopoietic stem cell transplant (AHSCT) in multiple sclerosis patients. Patients that failed to conventional therapies for multiple sclerosis (MS) underwent an approved protocol for AHSCT, which consisted of peripheral blood stem cell mobilization with cyclophosphamide and granulocyte colony-stimulating factor (G-CSF), followed by a conditioning regimen of BCNU, Etoposide, Ara-C, Melphalan IV, plus Rabbit Thymoglobulin. Thirty-eight MS patients have been transplanted since 1999. Thirty-one patients have been followed for more than 2 years (mean 8.4 years). There were 22 relapsing-remitting multiple sclerosis (RRMS) patients and 9 secondary progressive multiple sclerosis (SPMS) patients. No death related to AHSCT. A total of 10 patients (32.3%) had at least one relapse during post-AHSCT evolution, 6 patients in the RRMS group (27.2%) and 4 in the SPMS group (44.4%). After AHSCT, 7 patients (22.6%) experienced progression of disability, all within SP form. By contrast, no patients with RRMS experienced worsening of disability after a median follow-up of 5.4 years, 60% of them showed a sustained reduction in disability (SRD), defined as the improvement of 1.0 point in the expanded disability status scale (EDSS) sustains for 6 months (0.5 in cases of EDSS ≥ 5.5). The only clinical variable that predicted a poor response to AHSCT was a high EDSS in the year before transplant. AHSCT using the BEAM-ATG scheme is safe and efficacious to control the aggressive forms of RRMS.

    Two novel oxazolomycin isomers, oxazolomycins B (2) and C (3), were isolated from the fermentation broth of an oxazolomycin-producing strain, Streptomyces albus JA3453. Both compounds are geometrical isomers of oxazolomycin (1), the configurations of their triene moieties being (4'E, 6'E, 8'E) (2) and (4'Z, 6'E, 8'E) (3) while that of oxazolomycin (1) is (4'Z, 6'Z, 8'E). Compounds 2 and 3 exhibited potent inhibitory activity against crown gall formation with the same MIC (0.8 microgram/disk) as oxazolomycin. Compounds 2 and 3 showed no antibacterial activity against Agrobacterium tumefaciens, in contrast to oxazolomycin which has specific anti-A. tumefaciens activity.

    OBJECTIVE—To assess the quality of life (QoL) of patients with multiple sclerosis in France, Germany, and the United Kingdom with a cross sectional study.
METHODS—Patients were classified into three severity groups according to the expanded disability severity scale (EDSS); stage I, II, and III, corresponding to mild (EDSS 1.0-3.5), moderate (EDSS 4.0-6.0), or severe (EDSS 6.5-8.0) multiple sclerosis respectively. Ninety patients with multiple sclerosis and 30 control patients without multiple sclerosis were recruited in each country. Control patients were matched to the patients with multiple sclerosis according to age and sex. Quality of life was assessed using the functional status questionnaire (FSQ).
RESULTS—The aspects of QoL that were mostly affected in the three countries under study were physical function and general wellbeing. Social role function decreased with increased severity of disease in France and in particular in Germany. Multiple sclerosis did not seem to have an impact on psychological function. The QoL of control patients was systematically higher than that of patients with multiple sclerosis.
CONCLUSIONS—Use of such a generic scale showed that progression of multiple sclerosis is accompanied by a decrease in QoL and suggested that this could be a relevant measurement in assessing the effect of treatment and progression of disease. Variation between countries, however, may be important.

    The clinical features, diagnostic challenges, neuroimaging appearance, therapeutic options, and pathobiological research progress in childhood—and adolescent—onset multiple sclerosis have been informed by many new insights in the past 7 years. National programmes in several countries, collaborative research efforts, and an established international paediatric multiple sclerosis study group have contributed to revised clinical diagnostic definitions, identified clinical features of multiple sclerosis that differ by age of onset, and made recommendations regarding the treatment of paediatric multiple sclerosis. The relative risks conveyed by genetic and environmental factors to paediatric multiple sclerosis have been the subject of several large cohort studies. MRI features have been characterised in terms of qualitative descriptions of lesion distribution and applicability of MRI aspects to multiple sclerosis diagnostic criteria, and quantitative studies have assessed total lesion burden and the effect of the disease on global and regional brain volume. Humoral-based and cell-based assays have identified antibodies against myelin, potassium-channel proteins, and T-cell profiles that support an adult-like T-cell repertoire and cellular reactivity against myelin in paediatric patients with multiple sclerosis. Finally, the safety and efficacy of standard first-line therapies in paediatric multiple sclerosis populations are now appreciated in more detail, and consensus views on the future conduct and feasibility of phase 3 trials for new drugs have been proposed.

    The purpose of the study was to evaluate the prevalence of insomnia in multiple sclerosis patients with comorbid depression, associations between psychological symptoms, multiple sclerosis symptoms and insomnia, and to test effects of a 16-week protocol-based psychotherapy intervention for depression on insomnia symptoms. Participants with multiple sclerosis and depression (n = 127) were randomized to telephone administered cognitive behavioral therapy and telephone administered supportive emotion-focused therapy. Multiple sclerosis functional limitation was measured at baseline. Depression, insomnia, anxiety and quality of life were evaluated at pre treatment, mid treatment (8 weeks), and post treatment (16 weeks). Prevalence of insomnia ≥3 times per week was 78% at pre treatment and 43% at post treatment. Insomnia at baseline was associated with depression, multiple sclerosis related mood symptoms and anxiety. Middle of the night awakenings were associated with swallowing and speech problems. Improvements in insomnia were associated with improvement in depression and anxiety. Participants with residual insomnia were more likely to have major depressive disorder, greater multiple sclerosis severity, elevated anxiety and lower mental components of quality of life. Results demonstrate rates of insomnia in patients with comorbid multiple sclerosis and depression are higher than those reported in the general multiple sclerosis population and additional insomnia treatment is indicated beyond the treatment of comorbid psychological disorders.

    On March 10 to March 12, 2015, the National Institute of Neurological Disorders and Stroke and the Tuberous Sclerosis Alliance sponsored a workshop in Bethesda, Maryland, to assess progress and new opportunities for research in tuberous sclerosis complex with the goal of updating the 2003 Research Plan for Tuberous Sclerosis (http://www.ninds.nih.gov/about_ninds/plans/tscler_research_plan.htm). In addition to the National Institute of Neurological Disorders and Stroke and Tuberous Sclerosis Alliance, participants in the strategic planning effort and workshop included representatives from six other Institutes of the National Institutes of Health, the Department of Defense Tuberous Sclerosis Complex Research Program, and a broad cross-section of basic scientists and clinicians with expertise in tuberous sclerosis complex along with representatives from the pharmaceutical industry. Here we summarize the outcomes from the extensive premeeting deliberations and final workshop recommendations, including (1) progress in the field since publication of the initial 2003 research plan for tuberous sclerosis complex, (2) the key gaps, needs, and challenges that hinder progress in tuberous sclerosis complex research, and (3) a new set of research priorities along with specific recommendations for addressing the major challenges in each priority area. The new research plan is organized around both short-term and long-term goals with the expectation that progress toward specific objectives can be achieved within a five to ten year time frame.

    Background Evaluating the integrity of white matter tracts with diffusion tensor imaging may differentiate primary lateral sclerosis from progressive supranuclear palsy. Methods Thirty-three prospectively recruited subjects had standardized evaluations and diffusion tensor imaging: 3 with primary lateral sclerosis who presented with features suggestive of progressive supranuclear palsy, 10 with probable or definite progressive supranuclear palsy, and 20 matched controls. We compared fractional anisotropy of the corticospinal tract, superior cerebellar peduncle and body of the corpus callosum between groups. Results Both the primary lateral sclerosis and progressive supranuclear palsy subjects showed reduced fractional anisotropy in superior cerebellar peduncles and body of the corpus callosum compared to controls, but only primary lateral sclerosis subjects showed reductions in the corticospinal tracts. A ratio of corticospinal tract/superior cerebellar peduncle best distinguished the disorders (p<0.02). Conclusions The corticospinal tract/superior cerebellar peduncle ratio is a marker to differentiate primary lateral sclerosis from progressive supranuclear palsy. PMID:22517038

This group includes lysosomal storage disorders, various mitochondrial diseases, other neurometabolic disorders, and several other miscellaneous disorders. Recognition of a single-gene disorder as causal for a patient's 'multiple sclerosis-like' phenotype is critically important for accurate direction of patient management, and evokes broader genetic counselling implications for affected families. Here we review single gene disorders that have the potential to mimic multiple sclerosis, provide an overview of clinical and investigational characteristics of each disorder, and present guidelines for when clinicians should suspect an underlying heritable disorder that requires diagnostic confirmation in a patient with a definite or probable diagnosis of multiple sclerosis.

    Systemic sclerosis, or scleroderma, is a complex medical disorder characterized by limited or diffuse skin thickening with frequent involvement of internal organs such as lungs, gastrointestinal tract, or kidneys. Docetaxel is a chemotherapeutic agent which has been associated with cutaneous side effects. An uncommon cutaneous side effect of docetaxel is scleroderma-like skin changes that extend from limited to diffuse cutaneous systemic sclerosis. Several case reports have been published regarding the association of docetaxel and systemic sclerosis. However, those reports demonstrated the association between docetaxel and scleroderma-like skin changes without internal organ involvement. Here, we report a case of systemic sclerosis with pulmonary arterial hypertension and a microangiopathic kidney involvement induced by docetaxel chemotherapy. After an exhaustive literature review, this could be the first case of docetaxel-induced systemic sclerosis involving internal organs. PMID:28265474

    The purpose of this study is to examine the association between alcohol consumption and amyotrophic lateral sclerosis. Published literature on the association between alcohol consumption and amyotrophic lateral sclerosis was retrieved from the PubMed and Embase databases. Two authors independently extracted the data. The quality of the identified studies was evaluated according to the Newcastle-Ottawa scale. Subgroup and sensitivity analyses were performed and publication bias was assessed. Five articles, including one cohort study and seven case-control studies, and a total of 431,943 participants, were identified. The odds ratio for the association between alcohol consumption and amyotrophic lateral sclerosis was 0.57 (95 % confidence interval 0.51-0.64). Subgroup and sensitivity analyses confirmed the result. Evidence for publication bias was detected. Alcohol consumption reduced the risk of developing amyotrophic lateral sclerosis compared with non-drinking. Alcohol, therefore, has a potentially neuroprotective effect on the development of amyotrophic lateral sclerosis.

    Neuro-ophthalmologists typically observe a temporal pallor of the optic disc in patients with multiple sclerosis. Here, we describe the emergence of an idea to quantify these optic disc color changes in multiple sclerosis patients. We recruited 12 multiple sclerosis patients with previous optic neuritis attack and obtained photographs of their optic discs. The Laguna ONhE, a new colorimetric software using hemoglobin as the reference pigment in the papilla, was used for the analysis. The papilla of these multiple sclerosis patients showed greater pallor, especially in the temporal sector. The software detected the pallor and assigned hemoglobin percentages below normal reference values. Measurements of optic disc hemoglobin levels obtained with the Laguna ONhE software program had good ability to detect optic atrophy and, consequently, axonal loss in multiple sclerosis patients. This new technology is easy to implement in routine clinical practice.

    To explore experiences and perceptions of assistive technology, 14 people with multiple sclerosis, 5 carers and 4 occupational therapists participated in focus groups. Transcripts were analysed thematically drawing from illness self-regulation theory. Identified themes are as follows: critical multiple sclerosis events (developing symptoms/disability, delayed diagnosis and coping, public reaction and multiple sclerosis progression to assistive technology), matching assistive technology for continued use (acceptance of multiple sclerosis and assistive technology, realistic expectations, occupational therapist responsiveness, timing is crucial and carers and others) and impact of assistive technology (promoting or losing independence, stigma and embarrassment and redefining the carer). Acceptance and communication among those involved ensures assistive technology matches needs and maximises health and psychosocial outcomes.

  3. Treatment of Renal Angiomyolipoma and Other Hamartomas in Patients with Tuberous Sclerosis Complex.

    PubMed

    Samuels, Joshua A

    2017-03-16

    Tuberous sclerosis complex is an autosomal dominant genetic disease characterized by growth of benign tumors (hamartomas) in multiple organs, especially the kidneys, brain, heart, lungs, and skin. Tuberous sclerosis complex is usually caused by a mutation in either the tuberous sclerosis complex 1 or tuberous sclerosis complex 2 gene, resulting in constitutive activation of mammalian target of rapamycin signaling. Currently, mammalian target of rapamycin inhibitors are recommended in adult patients with tuberous sclerosis complex for the treatment of asymptomatic, growing renal angiomyolipoma that are >3 cm in diameter and pediatric or adult patients with brain lesions (subependymal giant cell astrocytoma) that either are growing or are not amenable to surgical resection. Clinical evidence suggests that systemic administration of a mammalian target of rapamycin inhibitor may provide concurrent improvements in multiple lesions and symptoms of tuberous sclerosis complex. With the major paradigm shift in consensus guidelines toward screening at diagnosis and ongoing monitoring and with the recent availability of an effective oral treatment, it is important that nephrologists have a thorough understanding of our role in the management of patients with tuberous sclerosis complex. Because the various manifestations of tuberous sclerosis complex typically emerge at different periods during patients' lifetimes, patients will need to be followed throughout their lives. Unlike brain and cardiac lesions, renal lesions are more likely to emerge as patients age and can grow at any time. Considerations regarding long-term medication administration for the potential control of multiple tuberous sclerosis complex manifestations will need to be addressed; these include the most appropriate starting dose, appropriate doses for tumor shrinkage versus prevention of regrowth, and management of adverse events.

    The aim of this study was to evaluate the enantioselective pharmacokinetics of cyclophosphamide and its metabolites 4-hydroxycyclophosphamide and carboxyethylphosphoramide mustard in patients with systemic or multiple sclerosis. Patients with systemic sclerosis (n = 10) or multiple sclerosis (n = 10), genotyped for the allelic variants of CYP2C9*2 and CYP2C9*3 and of the CYP2B6 G516T polymorphism, were treated with 50 mg cyclophosphamide/kg daily for 4 days. Serial blood samples were collected up to 24 hours after administration of the last cyclophosphamide dose. Cyclophosphamide, 4-hydroxycyclophosphamide, and carboxyethylphosphoramide enantiomers were analyzed in plasma samples using liquid chromatography-tandem mass spectrometry coupled to chiral column Chiralcel OD-R or Chiralpak AD-RH. Cytokines IL-2, IL-4, IL-6, IL-8, IL-10, IL- 12p70, IL-17, TNF-α, and INT-δ in the plasma samples collected before cyclophosphamide infusion were analyzed by Milliplex MAP human cytokine/chemokine. Pharmacokinetic parameters showed higher plasma concentrations of (S)-(-)-cyclophosphamide (AUC 215.0 vs 186.2 μg·h/mL for multiple sclerosis patients and 219.1 vs 179.2 μg·h/mL for systemic sclerosis patients) and (R)-4-hydroxycyclophosphamide (AUC 5.6 vs 3.7 μg·h/mL for multiple sclerosis patients and 6.3 vs 5.6 μg·h/mL for systemic sclerosis patients) when compared to their enantiomers in both groups of patients, whereas the pharmacokinetics of the carboxyethylphosphoramide metabolite was not enantioselective. Cytokines' plasma concentrations were similar between multiple and systemic sclerosis groups. The pharmacokinetics of cyclophosphamide is enantioselective in patients with systemic sclerosis and multiple sclerosis, with higher plasma concentrations of the (S)-(-)-cyclophosphamide enantiomer due to the preferential formation of the (R)-4-hydroxycyclophosphamide metabolite.

    Study Objectives: To report at a population level the prevalence of restless legs syndrome, insomnia, and the risk of obstructive sleep apnea in multiple sclerosis patients. Sleep patterns and associations with fatigue and daytime sleepiness were identified. Methods: A cross-sectional study was performed using a written survey that was mailed to 11,400 individuals from the Northern California Chapter of the National Multiple Sclerosis (MS) Society Database who self-identified as having MS. The survey included individual questions relating to demographics as well as several standard validated questionnaires related to primary sleep disorders, sleepiness, fatigue severity, and sleep patterns. Results: Among the 11,400 surveys mailed out, 2,810 (24.6%) were returned. Of these, 2,375 (84.5%) met the inclusion criteria. Among the completed surveys, 898 (37.8%) screened positive for obstructive sleep apnea, 746 (31.6%) for moderate to severe insomnia, and 866 (36.8%) for restless legs syndrome. In contrast, only 4%, 11%, and 12% of the cohort reported being diagnosed by a health care provider with obstructive sleep apnea, insomnia, and restless legs syndrome, respectively. Excessive daytime sleepiness was noted in 30% of respondents based on the Epworth Sleepiness Scale. More than 60% of the respondents reported an abnormal level of fatigue based on the Fatigue Severity Scale. Both abnormal fatigue and sleepiness scores were associated with screening positive for obstructive sleep apnea, insomnia, and restless legs syndrome. Conclusion: A significant percentage of MS subjects in our sample screened positive for one or more sleep disorders. The vast majority of these sleep disorders were undiagnosed. Greater attention to sleep problems in this population is warranted, especially in view of fatigue being the most common and disabling symptom of MS. Citation: Brass SD, Li CS, Auerbach S.

    The purpose of this report was to characterize the dynamics of the gene expression cascades induced by an IFN-beta-1a treatment regimen in multiple sclerosis patients and to examine the molecular mechanisms potentially capable of causing heterogeneity in response to therapy. In this open-label pharmacodynamic study design, peripheral blood was obtained from eight relapsing-remitting multiple sclerosis patients just before and at 1, 2, 4, 8, 24, 48, 120, and 168 h after i.m. injection of 30 micro g of IFN-beta-1a. The total RNA was isolated from monocyte-depleted PBL and analyzed using cDNA microarrays containing probes for >4000 known genes. IFN-beta-1a treatment resulted in selective, time-dependent effects on multiple genes. The mRNAs for genes implicated in the anti-viral response, e.g., double-stranded RNA-dependent protein kinase, myxovirus resistance proteins 1 and 2, and guanylate binding proteins 1 and 2 were rapidly induced within 1-4 h of IFN-beta treatment. The mRNAs for several genes involved in IFN-beta signaling, such as IFN-alpha/beta receptor-2 and Stat1, were also increased. The mRNAs for lymphocyte activation markers, such as IFN-induced transmembrane protein 1 (9-27), IFN-induced transmembrane protein 2 (1-8D), beta(2)-microglobulin, and CD69, were also increased in a time-dependent manner. The findings demonstrate that IFN-beta treatment induces specific and time-dependent changes in multiple mRNAs in lymphocytes of multiple sclerosis patients that could provide a framework for rapid monitoring of the response to therapy.

    Multiple sclerosis (MS) is a chronic disease of central nervous system. The multiple sclerosis information system (MSIS), such as other information system (IS), depends on identification, collection and processing of data for producing useful information. Lack of the integrated IS for collecting standard data causes undesirable effects on exchanging, comparing, and managing. The aim of this study was to recognize the role of the IS in the MS management and determine the advantages and barriers in implementing of the MSIS. The present study was a nonsystematized review that was done in order to recognize the role of the IS in the MS management. In this study, electronic scientific resources such as scientific magazines and books and published topics at conferences were used. We used key words (IS, chronic disease management, and multiple sclerosis), their combination or their synonyms in title, key words, abstracts, and text of English articles and published reports from 1980 until 2013, and by using search engines such as Google, Google Scholar and scientific databases and electronic issues such as iPubMed, sufficiently important difference, Scopus, Medlib, and Magiran for gathering information. More than 200 articles and reports were collected and assessed and 139 of them. Findings showed that the MSIS can reduce of disease expenses through continuously collecting correct, accurate, sufficient, and timely patients and disease nature information; recoding; editing; processing; exchanging, and distributing among different health care centers. Although the MSIS has many advantages; but, we cannot ignore cultural, economic, technical, organizational, and managerial barriers. Therefore, it is necessary to do studies for preventing, reducing, and controlling them. One of the ways is to recognize the advantages of the MSIS and usage information technology in optimizing disease management.

    Background In order to improve the treatment outcome in multiple sclerosis, it is important to document the factors that influence adherence to therapy. The purpose of this study was to determine patient perceptions and awareness of multiple sclerosis and its treatment, treatment adherence, and impact on quality of life and daily living. Methods This was a cross-sectional observational study performed in France. Each participating neurologist included the first three patients with relapsing-remitting multiple sclerosis who consulted after the start of the study. Data on clinical features were collected from a physician questionnaire and on disease and treatment perception and on quality of life from a patient autoquestionnaire. Results A total of 175 neurologists entered 202 patients in the study. The mean duration of disease was 8.0 ± 7.0 years, and immunomodulatory treatment had been administered for a mean duration of 3.0 ± 2.0 years. A total of 166 patients (82.2%) were treated with interferon-β preparations and 36 patients (17.8%) with glatiramer acetate. Eighty-five patients (42.1%) reported missing their injections from time to time and 36 patients (17.8%) reported “drug holidays”. The most frequently given reason for nonadherence was forgetfulness (38.7% of cases). Eighty-six patients (42.6%) and 70 patients (34.7%) claimed to be well informed about their disease and treatment, respectively. Adherence was significantly higher in well informed patients (P = 0.035). The majority of patients (176 patients, 87.1%) intended continuing their current treatment and 49.5% considered that their current treatment might reduce relapses. The most frequently reported side effect was muscle pain (124 patients, 61.4%). Conclusion Patient understanding of treatment for disease enhances treatment adherence. Greater patient involvement in disease management requires better communication between physicians and their patients. PMID:22536062

    Non-medicinal treatments of spasticity may be proposed in patients with multiple sclerosis as either an adjunct to pharmacological treatments or the first line of treatment. Assessment of non-medicinal treatments, whether manual, surgical or with instrumentation, shows it to be beneficial for limb spasticity. Studies also reveal that, contrary to expectations, physical exercise does not increase spasticity. This means that physical exercise may be prioritized and that sports practice should not be forbidden, provided that the patient has an adequate neurological status and takes sufficient breaks to avoid fatigue.

    To evaluate and compare the incidence and clinical features of Uhthoff's phenomenon in Japanese patients with neuromyelitis optica (NMO) and those with multiple sclerosis (MS), we asked 135 consecutive patients with MS and an NMO-related disorder (NMOrd) whether they experienced worse neurological symptoms after an increase in body temperature. Responses were obtained from 54 MS and 37 NMOrd patients. Uhthoff's phenomenon was observed in 26 MS (48.1%) and 20 NMOrd patients (54.1%). Motor and sensory symptoms were more frequent than visual symptoms in both diseases. The incidence of Uhthoff's phenomenon was similar in MS and NMOrd.

    A 49-year-old male with amyotrophic lateral sclerosis (ALS) was scheduled for gastrectomy. Anesthetic management was performed under general anesthesia with sevoflurane and epidural anesthesia with lidocaine. He showed increased response to vecuronium under monitoring of neuromuscular block. But he responded favorably to anticholineesterase. He had little pain and showed no progress in neurological symptoms in the postoperative period. Neuromuscular monitoring is essential in administrating non-depolarizing neuromuscular blocking agents to patients with ALS, and epidural anesthesia may be useful for perioperative management of patients with ALS.

    Seven autopsy patients with amyotrophic lateral sclerosis (ALS) in totally locked-in state (TLS) were examined neuropathologically. The patients were composed of 4 males and 3 females, and 3 with familial, 1 sporadic but with mutation in SOD1 gene, and 3 sporadic patients with unremarkable gene mutation. The brains weighed 715, 783, 1,019, 1,050, 1,170, 1,190 or 1,233 g. The tegmentum of the brain stem was markedly degenerated in every patient, and the tracts relating to the somatic sensory and auditory were involved in the lesions.

    Respiratory insufficiency is a critical problem in amyotrophic lateral sclerosis (ALS) patients. We herein present the case of an autopsied patient with sporadic ALS who underwent diaphragm pacing (DP). The pathology showed several localized adhesions with a markedly atrophied diaphragm. A marked loss of motor neurons with Bunina bodies and phosphorylated TDP-43 positive inclusions was found in the spinal cord and primary motor cortex. Mild hyalinization and a few multinucleated giant cells were present around the electrode tracks in the diaphragm. However, no infiltration of inflammatory cells was detected. Our findings suggest that full-time DP might not cause severe damage to adjacent diaphragm tissue. PMID:27904119

    Multiple sclerosis (MS) is the most common inflammatory disease of human central nervous system (CNS), which is characterized by inflammatory demyelination and neuroaxonal injury/loss. The majority of MS patients are diagnosed in early- to mid-adulthood; however, the onset of MS in childhood is being increasingly recognized. Although adults and children share important aspects of the disease, several features including course of the disease and a broader differential diagnosis are unique to children. This chapter summarizes recent insights and emphasizes that children with MS should be started on immunomodulatory therapies early in order to prevent future disability.

    Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system manifested with varying clinical course, pathology, and inflammatory patterns. There are multiple animal models that reflect different aspects of this heterogeneity. Collectively, these models reveal a balance between pathogenic and regulatory CD4+ T cells, CD8+ T cells and B cells that influences the incidence, timing, and severity of central nervous system autoimmunity. In this review we discuss experimental autoimmune encephalomyelitis (EAE) models that have been used to study the pathogenic and regulatory roles of these immune cells, models that recapitulate different aspects of the disease seen in patients with MS, and questions remaining for future studies.

    Safety of electroconvulsive therapy (ECT) in depressive patients with multiple sclerosis (MS) is still discussed and based solely on case reports. This kind of therapy was used in both unipolar depression and depression in bipolar disorder. It was suggested that ECT might cause the deterioration of neurological state (new MS lesions in magnetic resonance imaging). Moreover, there were also data indicating some anesthesiological complications and difficulties in patients with MS. We have presented a case of a patient who was treated with ECT and developed grand mal seizure after 14th electroconvulsive treatment.

    An increasing body of evidence suggests that patients who have major depressive disorder show alterations in immunologic markers including increases in proinflammatory cytokine activity and inflammation. Inflammation of the central nervous system is a pathologic hallmark of multiple sclerosis (MS). Patients affected by this disease also show a high incidence of depression. Accumulating evidence from animal studies suggests that some aspects of depression and fatigue in MS may be linked to inflammatory markers. This article reviews the current knowledge in the field and illustrates how the sickness behavior model may be applied to investigate depressive symptoms in inflammatory neurologic diseases.

    Systemic sclerosis is a chronic multi-organ autoimmune disease, leading to important clinical and psychological implications. Among organ complications, sexual dysfunction is a major issue for both male and female gender, with high prevalence and great impact on quality of life, although frequently not addressed by both clinicians and patients. While erectile dysfunction is the most common cause of sexual problems in males, genital tract and general physical changes are major contributors to sexual impairment in females. This review presents current state of the art on this topic, discussing published data on presentation, evaluation and therapeutic options.

    Systemic sclerosis has the highest case-specific mortality of any of the autoimmune rheumatic diseases as well as causing major morbidity. It is a major clinical challenge and one that has previously provoked substantial nihilism due to the limited therapeutic options available and perceived lack of evidence for clinical effectiveness of those treatments that are currently in use. However this situation is changing and there are emerging data supporting efficacy for some treatment approaches for this patient group together with a growing number of exciting potential novel approaches to treatment that are moving into the clinical arena. Some of the recent clinical trials are reviewed and discussed in detail. PMID:20534372

    The impact of prior neuro-ophthalmic syndromes on the performance on vision-based neuropsychological tasks in patients with multiple sclerosis (MS) is unknown. Two groups of MS participants, one with (Msos+) and the other without (Msos-), a history of neuro-ophthalmic syndromes, underwent neuropsychological assessment and were compared with healthy age- and education-matched controls (HC). Participants with Msos+ performed significantly worse on the symbol digit modalities test than the Msos- (P < 0.03) and the HC groups (P < 0.01) and coding (P < 0.01). A clinical history of neuro-ophthalmic syndromes is associated with reduced performance on visual processing speed tasks.

    A major challenge in multiple sclerosis (MS) is to develop biomarkers that could help in understanding individual MS patients, i.e. whether they are a responder or non-responder to therapy, which medicine is more effective, and the degree to which they may be entering the progressive phase of disease. In the last few years, a lot of attention has been drawn toward identification of diagnostic, prognostic, process-specific, and treatment-related biomarkers for MS. In this review, we will focus on the micro RNAs (miRNAs) as potential candidates for MS biomarkers.

    Systemic sclerosis (SSc) is a disorder characterized by immune dysfunction, microvascular injury, and fibrosis. Organ involvement in patients with SSc is variable; however, pulmonary involvement occurs in up to 90% of patients with SSc. Interstitial lung disease (ILD) is a major cause of mortality and, thus, a major determinant in the prognosis of patients with SSc. This review summarizes current findings about the characteristics of ILD in patients with SSc, selection of patients with SSc-ILD who are candidates for the treatment, and current treatment options.

    Raynaud’s phenomenon and digital ulcerations are two common clinical features seen in patients with systemic sclerosis. They are painful and lead to significant morbidity and altered hand function within this patient population. While currently there are no US Food and Drug Administration (FDA)-approved medications for the treatment of digital ulcerations in the United States, clinical trials have supported the use of pharmacologic and nonpharmacologic modalities in facilitating healing of existing digital ulcers and preventing formation of new ulcers. This article reviews the published data on these therapeutic options. PMID:26109864

The diagnosis of MS met the McDonald criteria and was based on clinical attacks separated in space and time, cerebrospinal fluid, and MRI. The diagnosis of HD was established by DNA testing, family history, and positron emission tomography. While a number of neurologic and autoimmune diseases have been reported with MS, this is the first co-occurrence of HD and MS. Salient features of both disorders are reviewed as well as the importance of obtaining a thorough family history.

    Our objective was to assess the role of Intrathecal Baclofen Therapy (ITB) in the cortical reorganization in a patient affected by multiple sclerosis (MS) undergoing physical therapy. We reported a case of a woman affected by MS and severe spasticity, who performed an fMRI examination, before and after the ITB implantation. The subject showed controlateral motor cortex activation after motor task. After a month of ITB implantation, patient showed ipsilateral and controlateral motor cortex activation although with a broader extension. fMRI examination supported the hypothesis of a central influence in patients who undergo physiotherapy and therapy with ITB.

    /sup 67/Gallium lung scans were performed in 19 patients with progressive systemic sclerosis (scleroderma). Results were expressed quantitatively as the /sup 67/Gallium Uptake Index. The mean total pulmonary /sup 67/Gallium Uptake Index in patients was significantly higher than that in controls (41 versus 25), and 4 patients (21%) fell outside the normal range. There were no clinical or laboratory variables that correlated with the /sup 56/Gallium uptake. Increased pulmonary /sup 67/Gallium uptake in scleroderma may prove useful as an index of pulmonary disease activity.

    Three female patients (ages 32, 37 and 27 years) developed progressive deficits of cognition in stages of multiple sclerosis in which physical disability ratings were low. Neuropsychological examination revealed severe cognitive impairments in the first two patients. Cognitive functioning was essentially intact in the third patient, although her work pace was significantly slowed. CT scanning of the brain showed cortical atrophy as well as white matter lesions in patients 1 and 2, and multiple lesions and oedema of predominantly white matter in patient 3. The differences of cognitive dysfunction between the third and the first two patients may be related to involvement of different anatomical structures. Images PMID:3806111

    CD24 is expressed on a broad range of cells in the immune and central nervous systems and appears to be required for development of experimental autoimmune encephalomyelitis in mice. Association of a CD24 Ala/Val coding polymorphism with susceptibility to and progression of multiple sclerosis was recently reported. We typed this coding polymorphism in a combined cohort of 1,180 cases and 1,168 unrelated and family-based controls from Belgium and the UK, but were unable to confirm either association. Since the CD24 gene is part of a segmental duplication, special care is required for the identification and genotyping of single nucleotide polymorphisms.

    In patients with systemic sclerosis (SSc), local disability of the hands and face, due to the involvement of skin, subcutaneous tissues and musculoskeletal system, is scarcely improved by pharmacological therapy, but may be treated efficaciously with rehabilitation, which can prevent and reduce local disability, thus ameliorating global disability and impaired Quality of Life, related to changes in the hands and face. In SSc, in order to be efficacious, rehabilitation should: 1. include and use both local treatments of hands and face and global rehabilitation techniques; 2. be different according to the different SSc phases and subsets; 3. include different techniques to tailor treatment to the personal needs and abilities of the patients.

    2014-01-01

    Brain lesions in patients with multiple sclerosis may lead to abnormal excitability of brainstem reflex circuits because of impairment of descending control pathways. We hypothesized that such abnormality should show in the analysis of blink reflex responses in the form of asymmetries in response size. The study was done in 20 patients with relapsing-remitting multiple sclerosis and 12 matched healthy subjects. We identified first patients with latency abnormalities (AbLat). Then, we analyzed response size by calculating the R2c/R2 ratio to stimulation of either side and the mean area of the R2 responses obtained in the same side. Patients with significantly larger response size with respect to healthy subjects in at least one side were considered to have abnormal response excitability (AbEx). We also examined the blink reflex excitability recovery (BRER) and prepulse inhibition (BRIP) of either side in search for additional indices of asymmetry in response excitability. Neurophysiological data were correlated with MRI-determined brain lesion-load and volume. Eight patients were identified as AbLat (median Expanded Disability Status Scale–EDSS = 2.75) and 7 of them had ponto-medullary lesions. Nine patients were identified as AbEx (EDSS = 1.5) and only 2 of them, who also were AbLat, had ponto-medullary lesions. In AbEx patients, the abnormalities in response size were confined to one side, with a similar tendency in most variables (significantly asymmetric R1 amplitude, BRER index and BRIP percentage). AbEx patients had asymmetric distribution of hemispheral lesions, in contrast with the symmetric pattern observed in AbLat. The brainstem lesion load was significantly lower in AbEx than in AbLat patients (p = 0.04). Asymmetric abnormalities in blink reflex response excitability in patients with multiple sclerosis are associated with lesser disability and lower tissue loss than abnormalities in response latency. Testing response excitability could

    Multiple sclerosis is characterized at the gross pathological level by the presence of widespread focal demyelinating lesions of the myelin-rich white matter. However, it is becoming clear that grey matter is not spared, even during the earliest phases of the disease. Furthermore, grey matter damage may have an important role both in physical and cognitive disability. Grey matter pathology involves both inflammatory and neurodegenerative mechanisms, but the relationship between the two is unclear. Histological, immunological and neuroimaging studies have provided new insight in this rapidly expanding field, and form the basis of the most recent hypotheses on the pathogenesis of grey matter damage.

    In acute phase of multiple sclerosis (MS) and neuromyelitis optica (NMO), plasmapheresis (PP) should be considered as the 2nd choice treatment when corticosteroid pulse therapy results in unsuccessful. It is believed that the beneficial effects of PP occur through the elimination of pathogenic humoral and plasma factors, including autoantibodies, complement components, and cytokines. In MS, several clinical trials have shown the efficacy. However, there have been no randomized controlled trials that demonstrated the efficacy of PP in NMO. There are three methods of PP, plasma exchange, double filtration plasmapheresis and immunoadsorption plasmapheresis, available in Japan. But the difference of efficacy among these 3 methods has not been fully evaluated.

    Multiple candidate biomarkers for amyotrophic lateral sclerosis (ALS) have emerged across a range of platforms. Replication of results, however, has been absent in all but a few cases, and the range of control samples has been limited. If progress toward clinical translation is to continue, the specific biomarker needs of ALS, which differ from those of other neurodegenerative disorders, as well as the challenges inherent to longitudinal ALS biomarker cohorts, must be understood. Appropriate application of multimodal approaches, international collaboration, presymptomatic studies, and biomarker integration into future therapeutic trials are among the essential priorities going forward.

    We report a case of a 23-year-old woman with a history of generalised tonic–clonic seizures, reddish brown maculopapular swelling over the face and an enlarging swelling over the scalp. Physical examinations revealed angiofibroma of the face and other typical cutaneous lesions of tuberous sclerosis, for example, shagreen patch and periungual fibroma. Scalp swelling was labelled as fibroma by dermatologists, which was further supported by the histopathological findings. Fibroma of the face is one of the commonest lesions, however, fibroma of the scalp is a rarely described entity. PMID:24748136

    2015-01-01

    Recent clinical and experimental studies indicate that multiple sclerosis develops as consequence of a failed interplay between genetic ("nature") and environmental ("nurture") factors. A large number of risk genes favour an autoimmune response against the body's own brain matter. New experimental data indicate that the actual trigger of this attack is however provided by an interaction of brain-specific immune cells with components of the regular commensal gut flora, the intestinal microbiota. This concept opens the way for new therapeutic approaches involving modulation of the microbiota by dietary or antibiotic regimens.

    Gait impairment is ubiquitous in multiple sclerosis (MS) and is often characterized by alterations in spatiotemporal parameters of gait. There is limited information concerning reliability of spatiotemporal gait parameters over clinical timescales (e.g. 6 months). The current report provides novel evidence that gait parameters of 74 ambulatory persons with MS with mild-to-moderate disability are reliable over 6-months (ICC's for overall sample range from 0.56 to 0.91) in the absence of any intervention above and beyond standard care. Such data can inform clinical decision-making and power analyses for designing RCTs (i.e., sample size estimates) involving persons with MS.

    For decades, persons with multiple sclerosis (MS) were counseled to avoid excessive physical activity and exercise because of concerns about worsening disease activity. Recent studies indicate that, not only can those with MS tolerate physical exercise, but that it is helpful in managing symptoms, preventing complications and comorbidities, and may possibly have neuroprotective actions. This article reviews previous studies on the effects of different exercise protocols in people with MS, and provides summaries of suggested exercise regimens that may be appropriate and beneficial for this patient population.

    The purpose of this phenomenological study was to explore the meaning of exercise in the lives of individuals with multiple sclerosis (MS) and describe the motivational basis that contributed to their exercise involvement. Twelve adults with MS (10 females, 2 males) between the ages of 32 and 56 years were interviewed. Analysis of transcribed interviews used an inductive approach. Three major themes emerged from thematic analysis of the qualitative data: exercising to maintain function and health, enhanced exercise self-efficacy, and feelings of hope and optimism. Findings were interpreted within the conceptual framework of self-efficacy and a disability-only social context.

    The purpose of this study was to investigate the factor structure of the Multiple Sclerosis Impact Scale (MSIS-29) to assess its suitability for modeling the impact of MS on a nation-wide sample of individuals from the United States. Investigators completed a Confirmatory Factor Analysis (CFA) to examine the two-factor structure proposed by Hobart et al. [17]. Although the original MSIS-29 factor structure did not fit the data exactly, the hypothesized two-factor model was partially supported in the current data. Implications for future instrument development and rehabilitation practice are discussed.

    Respiratory insufficiency is a critical problem in amyotrophic lateral sclerosis (ALS) patients. We herein present the case of an autopsied patient with sporadic ALS who underwent diaphragm pacing (DP). The pathology showed several localized adhesions with a markedly atrophied diaphragm. A marked loss of motor neurons with Bunina bodies and phosphorylated TDP-43 positive inclusions was found in the spinal cord and primary motor cortex. Mild hyalinization and a few multinucleated giant cells were present around the electrode tracks in the diaphragm. However, no infiltration of inflammatory cells was detected. Our findings suggest that full-time DP might not cause severe damage to adjacent diaphragm tissue.

    Homocysteine is a sulfhydryl-containing amino acid that is derived from dietary methionine, and there has been increasing evidence that elevated plasma homocysteine levels are associated with increased risk of cardiovascular diseases, including carotid, coronary and peripheral arterial disease (PAD). The association of plasma homocysteine levels with peripheral vascular involvements, such as Raynaud phenomenon (RP), digital ulcers (DU) in systemic sclerosis (SSc) patients has not been well studied. The objective of this study was to examine plasma homocysteine levels and their clinical associations in patients with SSc. Plasma homocysteine levels in 151 Japanese patients with SSc and 20 healthy controls were examined. No significant differences were observed in plasma homocysteine levels between SSc patients and healthy individuals. Demographic and clinical features of the SSc patients revealed that severe skin sclerosis, anti-topoisomerase I antibody positivity, complications of DU, acro-osteolysis (AO) and interstitial lung disease (ILD) were significantly more prevalent among the patients with elevated plasma homocysteine levels. The plasma homocysteine levels were positively correlated with modified Rodnan total skin score. The plasma homocysteine levels in the SSc patients with DU, AO and ILD were significantly higher than those in the SSc without DU, AO and ILD, respectively. Plasma homocysteine levels did not correlate with either the mean or max intima-media thickness (IMT) or plaque score, suggesting that plasma homocysteine levels might not be associated with carotid artery atherosclerosis in SSc patients. The measurement of plasma homocysteine levels in SSc patients might be useful for the risk stratifications of severe skin sclerosis, DU and AO.

    Amyotrophic lateral sclerosis (ALS), a rapidly progressive, invariably fatal disease, involves mixed upper and lower motor neurons in different spinal cord regions. Patients with bulbar onset progress more rapidly than patients with limb onset or with a lower motor neuron presentation. Recent descriptions of regional variants suggest some patients have ALS isolated to a single spinal region for many years, including brachial amyotrophic diplegia, leg amyotrophic diplegia, and isolated bulbar palsy. Clearer definitions of regional variants will have implications for prognosis, understanding the pathophysiology of ALS, identifying genetic factors related to slower disease progression, and future planning of clinical trials.

    Multiple sclerosis is a chronic autoimmune demyelinating disease of the central nervous system, which is thought to be triggered by environmental factors in genetically susceptible individuals leading to activation of autoreactive T lymphocytes. Large multi-centre genome-wide association studies have identified multiple genetic risk loci in multiple sclerosis. In this study, we investigated T cell transcriptomic changes in experimental autoimmune encephalomyelitis, an animal model for multiple sclerosis. We correlated these findings with the multiple sclerosis risk genes postulated by the most recent Immunochip analysis and found that multiple sclerosis susceptibility genes were significantly regulated in experimental autoimmune encephalomyelitis. Our data indicate that nine distinct genes associated with multiple sclerosis risk, Bach2, Il2ra, Irf8, Mertk, Odf3b, Plek, Rgs1, Slc30a7 and Thada, can be confirmed to be differentially regulated in pathogenic CD4(+) T cells. During the effector phase within the inflamed CNS, CD4(+) T cells undergo comprehensive transformation and we identified key transcription factors and signalling networks involved in this process. The transformation was linked to metabolic changes with the involvement of liver X receptor/retinoid X receptor signalling and cholesterol biosynthesis, which might control the T cell effector function in the central nervous system. Thus, our study confirms the involvement of multiple sclerosis risk genes in the pathophysiology of the animal model and sheds light on additional disease-relevant inflammatory networks.

    Transforming growth factor beta (TGFβ) signalling is critical for regulatory T cell development and function, and regulatory T cell dysregulation is a common observation in autoimmune diseases, including multiple sclerosis. In a comprehensive miRNA profiling study of patients with multiple sclerosis naïve CD4 T cells, 19 differentially expressed miRNAs predicted to target the TGFβ signalling pathway were identified, leading to the hypothesis that miRNAs may be responsible for the regulatory T cell defect observed in patients with multiple sclerosis. Patients with multiple sclerosis had reduced levels of TGFβ signalling components in their naïve CD4 T cells. The differentially expressed miRNAs negatively regulated the TGFβ pathway, resulting in a reduced capacity of naïve CD4 T cells to differentiate into regulatory T cells. Interestingly, the limited number of regulatory T cells, that did develop when these TGFβ-targeting miRNAs were overexpressed, were capable of suppressing effector T cells. As it has previously been demonstrated that compromising TGFβ signalling results in a reduced regulatory T cell repertoire insufficient to control autoimmunity, and patients with multiple sclerosis have a reduced regulatory T cell repertoire, these data indicate that the elevated expression of multiple TGFβ-targeting miRNAs in naïve CD4 T cells of patients with multiple sclerosis impairs TGFβ signalling, and dampens regulatory T cell development, thereby enhancing susceptibility to developing multiple sclerosis.

    Signs and symptoms of multiple sclerosis are usually attributed to demyelinating lesions in the spinal cord or cerebral cortex. The hypothalamus is a region that is often overlooked yet controls many important homeostatic functions, including those that are perturbed in multiple sclerosis. In this review we discuss how hypothalamic dysfunction may contribute to signs and symptoms in people with multiple sclerosis. While dysfunction of the hypothalamic-pituitary-adrenal axis is common in multiple sclerosis, the effects and mechanisms of this dysfunction are not well understood. We discuss three hypothalamic mechanisms of fatigue in multiple sclerosis: (1) general hypothalamic-pituitary-adrenal axis hyperactivity, (2) disordered orexin neurotransmission, (3) abnormal cortisol secretion. We then review potential mechanisms of weight dysregulation caused by hypothalamic dysfunction. Lastly, we propose future studies and therapeutics to better understand and treat hypothalamic dysfunction in multiple sclerosis. Hypothalamic dysfunction appears to be common in multiple sclerosis, yet current studies are underpowered and contradictory. Future studies should contain larger sample sizes and standardize hormone and neuropeptide measurements.

    Regulatory T cells (Treg cells), defined as CD4(+) CD25(+) FoxP3(+) T cells by expression of CD4, high-affinity IL-2 receptor and the transcription factor, forkhead box P3 (FoxP3). They play a pivotal role in protecting individuals from autoimmunity and a growing body of evidence suggests their role in the prevention of multiple sclerosis development. However, there are discrepancies about the type of defect in the Treg cells of multiple sclerosis patients and especially whether the Treg number alteration could be contributed to multiple sclerosis pathogenesis. Indeed, whether low number of Treg cells can be a risk factor contributing to multiple sclerosis pathogenesis is the matter of debate and there is not any comprehensive agreement on it. Thus, the objective of this systematic review and meta-analysis was to precisely quantify the nature and magnitude of the association between Treg cell number and the risk ratio/odds ratio (OR) of multiple sclerosis in the case-control studies. Hence, medical databases of Embase, PubMed/Medline, PubMed, PubMed Central and SCOPUS were searched for empirical papers using "Regulatory T cell frequency", "Treg frequency" in combination with "multiple sclerosis". In the case-control studies, papers were reviewed for inclusion/exclusion criteria and 8 publications were included. Under random-effect model meta-analysis the data showed that the frequency of Treg cells was not a risk factor in multiple sclerosis using current laboratory methods.

    Tuberous sclerosis complex is an autosomal dominant genetic disorder that confers a high risk for neurodevelopmental disorders, such as autism spectrum disorder and intellectual disability. Studies have demonstrated specific delays in visual reception skills that may predict the development of autism spectrum disorder and intellectual disability. Based on evidence for alterations in the retinogeniculate pathway in animal models of tuberous sclerosis complex, we asked whether children with tuberous sclerosis complex demonstrate alterations in early visual processing that may undermine the development of higher-level visual behaviors. Pattern-reversal visual evoked potentials were recorded in infants with tuberous sclerosis complex (n = 16) and typically developing infants (n = 18) at 12 months of age. Infants with tuberous sclerosis complex demonstrated remarkably intact visual evoked potentials even within the context of intellectual disability and epilepsy. Infants with tuberous sclerosis complex show intact visual cortical processing, suggesting that delays in visually mediated behaviors in tuberous sclerosis complex may not be rooted in early visual processing deficits.

  11. A patient with amyotrophic lateral sclerosis and atypical clinical and electrodiagnostic features: a case report

    PubMed Central

    2011-01-01

    Introduction Amyotrophic lateral sclerosis is a rapidly progressive, fatal neurodegenerative disorder for which there is no effective treatment. The diagnosis is dependent on the clinical presentation and consistent electrodiagnostic studies. Typically, there is a combination of upper and lower motor neuron signs as well as electrodiagnostic studies indicative of diffuse motor axonal injury. The presentation of amyotrophic lateral sclerosis, however, may be variable. At the same time, the diagnosis is essential for patient prognosis and management. It is therefore important to appreciate the range of possible presentations of amyotrophic lateral sclerosis. Case presentation We present the case of a 57-year-old Caucasian man with pathological findings on postmortem examination consistent with amyotrophic lateral sclerosis but atypical clinical and electrodiagnostic features. He died after a rapid course of progressive weakness. The patient did not respond to immunosuppressive therapy. Conclusion Amyotrophic lateral sclerosis should be considered in patients with a rapidly progressive, unexplained neuropathic process. This should be true even if there are atypical clinical and electrodiagnostic findings. Absence of response to therapy and the development of upper motor neuron signs should reinforce the possibility that amyotrophic lateral sclerosis may be present. Since amyotrophic lateral sclerosis is a fatal illness, however, the possibility of this disease in patients with atypical clinical features should not diminish the need for a thorough diagnostic evaluation and treatment trials.

    Massive stars, possibly red supergiants, which retain extended hydrogen envelopes until core collapse, produce Type II plateau (IIP) supernovae. The ejecta from these explosions shocks the circumstellar matter originating from the mass loss of the progenitor during the final phases of its life. This interaction accelerates particles to relativistic energies which then lose energy via synchrotron radiation in the shock-amplified magnetic fields and inverse Compton scattering against optical photons from the supernova. These processes produce different signatures in the radio and X-ray parts of the electromagnetic spectrum. Observed together, they allow us to break the degeneracy between shock acceleration and magnetic field amplification. In this work, we use X-rays observations from the Chandra and radio observations from the Australia Telescope Compact Array to study the relative importance of processes which accelerate particles and those which amplify magnetic fields in producing the non-thermal radiation from SN 2011ja. We use radio observations to constrain the explosion date. Multiple Chandra observations allow us to probe the history of variable mass loss from the progenitor. The ejecta expands into a low-density bubble followed by interaction with a higher density wind from a red supergiant consistent with M{sub ZAMS} {approx}> 12 M{sub Sun }. Our results suggest that a fraction of Type IIP supernovae may interact with circumstellar media set up by non-steady winds.

    Studies in the last 10 years of dust formation in core-collapse supernovae (CCSNe) have found only small amounts, ~0.001 solar masses. This is far less than the amount needed to account for the large masses of dust seen in some high redshift galaxies. However, the recent discovery of ~1 solar mass of cold dust in the ejecta of SN 1987A has has caused a complete re-evaluation of dust formation in CCSNe. It has been suggested that the CCSNe are continuously forming dust so that by the time they are about 25 years old they will have dust masses similar to SN 1987A. However, there is a wide time gap between the CCSNe that have been studied recently and SN 1987A. We plan to use the sensitivity of Spitzer to detect dust emission from CCSNe 5 or more years after explosion. Radiative transfer models will be used to estimate the dust masses. This proposal is to continue our study of two interesting SNe 2010jl and 2011ja. These observations are part of a long term study requiring multiple epochs of Spitzer observations to look for evidence of continuous dust formation. These observations will help shed light on the mystery of dust in SN 1987A.

    2013-08-01

    Mutations in the gene superoxide dismutase 1 (SOD1) are causative for familial forms of the neurodegenerative disease amyotrophic lateral sclerosis. When the first SOD1 mutations were identified they were postulated to give rise to amyotrophic lateral sclerosis through a loss of function mechanism, but experimental data soon showed that the disease arises from a--still unknown--toxic gain of function, and the possibility that loss of function plays a role in amyotrophic lateral sclerosis pathogenesis was abandoned. Although loss of function is not causative for amyotrophic lateral sclerosis, here we re-examine two decades of evidence regarding whether loss of function may play a modifying role in SOD1-amyotrophic lateral sclerosis. From analysing published data from patients with SOD1-amyotrophic lateral sclerosis, we find a marked loss of SOD1 enzyme activity arising from almost all mutations. We continue to examine functional data from all Sod1 knockout mice and we find obvious detrimental effects within the nervous system with, interestingly, some specificity for the motor system. Here, we bring together historical and recent experimental findings to conclude that there is a possibility that SOD1 loss of function may play a modifying role in amyotrophic lateral sclerosis. This likelihood has implications for some current therapies aimed at knocking down the level of mutant protein in patients with SOD1-amyotrophic lateral sclerosis. Finally, the wide-ranging phenotypes that result from loss of function indicate that SOD1 gene sequences should be screened in diseases other than amyotrophic lateral sclerosis.

    Data on familial recurrence rates of complex diseases such as multiple sclerosis give important hints to aetiological factors such as the importance of genes and environment. By linking national registries, we sought to avoid common limitations of clinic-based studies such as low numbers, poor representation of the population and selection bias. Through the Swedish Multiple Sclerosis Registry and a nationwide hospital registry, a total of 28 396 patients with multiple sclerosis were identified. We used the national Multi-Generation Registry to identify first and second degree relatives as well as cousins, and the Swedish Twin Registry to identify twins of patients with multiple sclerosis. Crude and age corrected familial risks were estimated for cases and found to be in the same range as previously published figures. Matched population-based controls were used to calculate relative risks, revealing lower estimates of familial multiple sclerosis risks than previously reported, with a sibling recurrence risk (λs = 7.1; 95% confidence interval: 6.42-7.86). Surprisingly, despite a well-established lower prevalence of multiple sclerosis amongst males, the relative risks were equal among maternal and paternal relations. A previously reported increased risk in maternal relations could thus not be replicated. An observed higher transmission rate from fathers to sons compared with mothers to sons suggested a higher transmission to offspring from the less prevalent sex; therefore, presence of the so-called 'Carter effect' could not be excluded. We estimated the heritability of multiple sclerosis using 74 757 twin pairs with known zygosity, of which 315 were affected with multiple sclerosis, and added information from 2.5 million sibling pairs to increase power. The heritability was estimated to be 0.64 (0.36-0.76), whereas the shared environmental component was estimated to be 0.01 (0.00-0.18). In summary, whereas multiple sclerosis is to a great extent an inherited trait

    Background and Purpose Susceptibility MRI contrast variations reflect alterations in brain iron and myelin content- making this imaging tool relevant to studies of multiple sclerosis lesion heterogeneity. In this study we aimed to characterize the relationship of high-field, susceptibility contrasts in multiple sclerosis lesions to clinical outcomes. Materials and Methods Twenty-four subjects with multiple sclerosis underwent 7-tesla MRI of the brain, disability exams, and a fatigue inventory. R2*, frequency, and relative susceptibility (from quantitative susceptibility mapping) were analyzed in 306 white matter lesions. Results Most lesions were hypointense on R2* (88% without a rim, 5% with). Lesions that were hyperintense on quantitative susceptibility mapping were more frequent in relapsing-remitting than progressive multiple sclerosis (54% vs. 35%, p = 0.018). Hyperintense lesion rims on quantitative susceptibility maps were more common in progressive multiple sclerosis and higher levels of disability and fatigue. Mean lesion R2* was inversely related to disability and fatigue and significantly reduced in progressive multiple sclerosis. Relative susceptibility was lower lesions in progressive multiple sclerosis (median -0.018 ppm, range -0.070 – 0.022) than relapsing-remitting (median -0.010 ppm, range -0.062 – 0.052, p = 0.003). Conclusion A progressive clinical phenotype, greater disability, and fatigue were associated with lower R2* and relative susceptibility values (suggestive of low iron due to oligodendrocyte loss) and rimmed lesions (suggestive of chronic inflammation) in this multiple sclerosis cohort. Lesion heterogeneity on susceptibility MRI may help explain disability in multiple sclerosis and provide a window into the processes of demyelination, oligodendrocyte loss, and chronic lesion inflammation.

    This study evaluated the specialized housing, transportation, and resource needs and barriers of adults with MS. Information pertaining to barriers and barrier removal strategies related to housing and transportation issues for adults with MS was gathered as part of a national survey of a randomly selected and representative sample of 5082 adults with MS, in cooperation with affiliate chapters of the National Multiple Sclerosis Society (NMSS) and the North American Research Committee on Multiple Sclerosis (NARCOMS). This article presents a qualitative analysis of participants' responses to questions addressing: (a) barriers to obtaining specialized housing and adapted transportation for individuals with MS, (b) factors contributing to maintenance of an independent lifestyle, and (c) information and referral resources pertinent to obtaining specialized housing and adapted transportation. The results provide the first assessment of these issues on a national scale and underscore the need for increased access to professional consultation, financial resources, and housing modification information and resources to enable persons with MS to obtain the specialized housing needed to maintain maximal independent lifestyles.

    2013-01-01

    Background Potential biomarkers to aid diagnosis and therapy need to be identified for Amyotrophic Lateral Sclerosis, a progressive motor neuronal degenerative disorder. The present study was designed to identify the factor(s) which are differentially expressed in the cerebrospinal fluid (CSF) of patients with sporadic amyotrophic lateral sclerosis (SALS; ALS-CSF), and could be associated with the pathogenesis of this disease. Results Quantitative mass spectrometry of ALS-CSF and control-CSF (from orthopaedic surgical patients undergoing spinal anaesthesia) samples showed upregulation of 31 proteins in the ALS-CSF, amongst which a ten-fold increase in the levels of chitotriosidase-1 (CHIT-1) was seen compared to the controls. A seventeen-fold increase in the CHIT-1 levels was detected by ELISA, while a ten-fold elevated enzyme activity was also observed. Both these results confirmed the finding of LC-MS/MS. CHIT-1 was found to be expressed by the Iba-1 immunopositive microglia. Conclusion Elevated CHIT-1 levels in the ALS-CSF suggest a definitive role for the enzyme in the disease pathogenesis. Its synthesis and release from microglia into the CSF may be an aligned event of neurodegeneration. Thus, high levels of CHIT-1 signify enhanced microglial activity which may exacerbate the process of neurodegeneration. In view of the multifold increase observed in ALS-CSF, it can serve as a potential CSF biomarker for the diagnosis of SALS. PMID:24295388

    Multiple sclerosis is the most common cause of progressive neurological disability in young adults. This disease involves damage to the myelin sheath that normally insulates the electrical activity of nerve fibers. This leads to a wide range of symptoms as specific nerves become injured and lose their function. Epidemiological and experimental studies show that genetic alterations, antioxidant enzyme abnormalities and autoimmunity are risk factors for developing the disease. Recent evidence suggests that inflammation and oxidative stress within the central nervous system are major causes of ongoing tissue damage. Resident central nervous system cells and invading inflammatory cells release several reactive oxygen and nitrogen species which cause the histopathological features of multiple sclerosis: demyelization and axonal damage. The interplay between inflammatory and neurodegenerative processes results in an intermittent neurological disturbance followed by progressive accumulation of disability. Reductions in inflammation and oxidative stress status are important therapeutic strategies to slow or halt the disease processes. Therefore, several drugs are currently in trial in clinical practice to target this mechanism; particularly the use of supplements such as antioxidants and omega-3 polyunsaturated fatty acids, in order to improve the survival and quality of patients' lives.

    Classic treatment for pyriform sinus fistula (PSF) has been surgical excision; however, less invasive therapeutic alternatives whose aim is the obliteration of the sinus have been described subsequently. The authors present a technical modification of endoscopic sclerosis with diathermy (ESD): continuous infusion of air flow through the flexible endoscope was used to distend the pyriform sinus and facilitate recognition of the fistula opening. The sinus obliteration was performed with a wire guide and diathermy. In the last 15 years, 9 patients were diagnosed of suffering from PSF in our institution. Initial treatment was antibiotics therapy associated in some cases to cervical abscess drainage. Fistulectomy was performed in 4 cases and ESD in 4. The ninth patient received both treatments, performing electrocauterization after a surgical recurrence. Three of the patients who underwent surgery relapsed; none treated by ESD did, or had any complications. In our experience, endoscopic sclerosis with pneumatic distension is a simple technique, reproducible, not invasive and very effective; hence we consider it might become a first line therapy for PSF.
