Multiple SclerosisThis will be prospective, multicentre, observational study. Patients who will initiate treatment with IFNβ-1b (Betaferon) will be followed up to 6 months. Baseline visit (visit 0) i.e. treatment initiation plus four follow-up visits (visits 1-4). For each patient demographics, medical history data, safety parameters, presence of flu-like symptoms and measures to prevent or treat these symptoms will be collected.
Effect of Fingolimod on the Cardiac Autonomic Regulation in Patients With Multiple Sclerosis
Relapse-remitting Multiple SclerosisThe purpose of this study is to study the effect of fingolimod on cardiac autonomic regulation in patients with relapse-remitting multiple sclerosis. This will be done by measuring heart rate variability from the 24-hour Holter recording and myocardial ventricular repolarisation patterns from the 12-lead electrocardiogram tracings. The fingolimod treatment is prescribed according to the accepted drug label.
Measuring Active Microglia in Progressive Multiple Sclerosis
Secondary Progressive Multiple SclerosisThis is pilot study designed to quantifying the innate immune inflammatory burden in a cohort of secondary progressive multiple sclerosis subjects. Innate immunity is recognized as a major cause of tissue injury in central nervous system (CNS) disease. Our hypothesis is that the innate immune response is heightened in SPMS as compared to healthy controls (HC's) and this activity increases over time and correlates with ongoing neuronal loss and disability. The investigators will test this hypothesis by using highly specific molecular imaging techniques, specifically PET, in conjunction with high field MRI. The investigators will utilize the PET radioligand [11C]PK11195 which will be used as a marker of activated macrophages/microglia. The investigators will correlate [11C]PK11195 uptake with conventional measures of inflammation and neuronal integrity on high-resolution MRI. SPMS subjects will have two baseline [11C]PK-11195 PET scans (separated by 24 to 72 hours, test-retest) and subsequent scans at 6, 12 and 24 months. SPMS Subjects will have brain MRI's at baseline, 6, 12 and 24 months. Healthy Controls will have 2 baseline PET scans and one MRI.
Characterization of Patients With Tuberous Sclerosis Complex, Lymphangioleiomyomatosis and Angiomyolipoma...
Tuberous SclerosisLymphangioleiomyomatosis1 moreTuberous Sclerosis Complex (TSC) is a multisystemic autosomal dominant disease that is characterized by the development of benign neoplasms in brain, kidney, lung, skin and heart. TSC is caused by mutations in TSC1 and/or TSC2 genes, which encode, respectively, hamartin and tuberin, that are involved in the regulation of cell proliferation, cell cycle and protein synthesis. Most patients exhibit dermatological, renal, neurological and pulmonary (lymphangioleiomyomatosis, LAM) manifestations. Neurological involvement include subependymal nodules, subependymal giant cell astrocytomas and cortical tubers. LAM is characterized by the proliferation of LAM cells around the airways, blood vessels and lymphatics, which result in vascular and airway obstruction and cyst formation. The most frequent TSC manifestation in the kidney is the development of angiomyolipomas (AML). Dermatologic lesions represent the most common manifestations of TSC, mainly hypomelanotic macules and facial angiofibromas. The most significant functional implication of the tuberin-hamartin complex is its regulatory role upon the mammalian target of rapamycin (mTOR) pathway. Mutations in TSC1 or TSC2 lead to increased mTOR activity and favor tumor development and growth. All lesions associated with TSC, sporadic LAM and sporadic AML share a common molecular pathogenesis, based on TSC1/TSC2 mutations and mTOR hyperactivity. Up to date, TSC patients have been followed in separated medical services in our institution, according to their predominant phenotype. The current knowledge, however, suggest that the ideal follow up of such patients should be conducted in an integrated fashion among the specialties associated with the main disease manifestations. Experts in TSC from each of these areas have recently created a TSC/LAM/AML integrated program in the University of São Paulo Medical Center, and his project will be initiated with the generation of an integrated TSC/LAM/AML registry, which intends not only to clinically characterize this patient population but also to document the employed treatment modalities. Once this first goal is achieved, clinical trials are planned to be performed. The central aim of this observational study is to clinically characterize the TSC/LAM/AML subject population followed and referred to the University of São Paulo Medical Center. Specific aims: To characterize the pulmonary, the neurological, the renal and the dermatologic phenotypes of this patient population.
DTI in Children With Multiple Sclerosis
Multiple Sclerosis - Relapsing RemittingClinically Isolated Syndrome1 moreThis is a prospective, non-randomised, non-blinded, single center study of children and adolescents with multiple sclerosis and clinically isolated syndrome to detect differences or early changes in diffusion-weighted imaging (DTI) by magnetic resonance imaging (MRI).
Endothelial Microparticles in Systemic Sclerosis Pulmonary Hypertension
Systemic SclerosisPulmonary Hypertension1 moreSystemic sclerosis (SSc, also known as scleroderma) is a disease characterized by fibrosis of the skin and organs, inflammation, and an abnormal endothelial cell lining inside of vessels. A common and deadly complication of SSc is pulmonary hypertension (PH), which is an abnormal elevation in the blood pressure within the lung blood vessels. Early identification and treatment of PH is important in SSc, and no clinical factors can predict which patients will develop PH with acceptable accuracy. A potential marker of PH in SSc is the presence of increased amounts of endothelial microparticles (EMPs), which are substances circulating in the blood that were released from damaged vessel wall endothelial lining. A main goal of this study is to investigate if there is a difference in EMP levels between SSc patients with and without PH. The investigators will also use human endothelial cells in a lab environment to test whether these EMPs isolated from SSc patients are actually causing damage to the vessel lining. Lastly, the investigators will investigate the potential benefit of a medication used after transplant, mycophenolate mofetil (MMF). This will be done by causing damage to isolated human endothelial cells and treating them with MMF. The main goal of this portion of our study is to see if EMP levels are reduced when cells are treated with MMF. Overall, the investigators anticipate the following outcomes of this study: 1) use EMP levels to differentiation patients with SSc who have PH from those without PH, 2) use EMPs to understand how endothelial damage occurs in SSc, and 3) use EMPs to help us develop new treatments for patients with vascular diseases.
Using Optical Coherence Tomography to Capture Retinal Microvascular Changes Associated With Multiple...
Multiple SclerosisRecent studies have shown that people with multiple sclerosis (MS) who also have diseases related to vascular health such as high cholesterol, high blood pressure, diabetes, cardiovascular disease, and others, may end up more disabled than people with MS who don't have those diseases. This has led to a growing interest in the role of vascular diseases in MS since they may provide another avenue of MS treatment. Some also think that vascular disease may even be a cause of MS. The back of the eye, the retina, is well-suited to studying vascular diseases as blood vessels can be seen even on routine examination of the eye by eye doctors. These specialists are used to seeing changes in retinal blood vessels due to diseases known to affect the eyes such as glaucoma and diabetes. Sophisticated techniques for examining the retina allow for not only visualization of blood vessels, but the rate of blood flow through the blood vessels as well. These blood flow changes are thought to come before changes in what the blood vessels look like, and so may be able to detect problems even earlier than routine examination of the retina by eye doctors. Retinal blood flow has never been carefully studied in MS. Given that MS affects the retina due to the late effects of inflammation of the optic nerve, or optic neuritis, the investigators expect to see altered blood flow in the retinal blood vessels of people with MS compared to healthy control subjects. If so, the investigators can then use retinal blood flow as a way to measure therapies that target vascular diseases in the MS population and determine if those therapies can alter the course of disease.
Observational Study for Assessment of the Effect of Fampyra on the Manual Function of Persons With...
Multiple SclerosisMultiple Sclerosis (MS) is the most common chronic neurological disease affecting young adults, with onset usually at age 20-40 years. Women are affected 3-4 times more than men. The disease is characterized by 2 main phenotypes: relapsing-remitting or progressive course. Several immunotherapies were developed in the last 10-15 years for the long term management of the relapsing type of disease. Treatment with these drugs decreases disease activity though cannot cure it. There are few treatments for targeting specific symptoms of MS, such as Provigil for the treatment of fatigue. Regarding problems related to spasticity and related gait problems , which is stated by over 40 % of MS patients as their main complaint - present treatments include: non-pharmacological treatments such as physiotherapy, occupational therapy, hydrotherapy and pharmacological treatments such as Baclofen, Tizanidine and Botulinium toxin. Fampyra (Fampridine) has recently been approved for use in patients with gait problems. This drug acts by blocking potassium ion channels and has been proven to improve walking in 35% of the patients after one month of treatment. The effect of Fampyra on hand function in MS has yet to be studied. The aim of this research project is to assess the effect of treatment with Fampyra on manual function of patients with MS. The investigators hypothesize that through the same mechanism by which Fampyra improves ambulation it can also improve manual function. MS patients visiting the MS center clinic at the Carmel Medical Center, with walking disabilities eligible to Fampyra treatment, that have also manual dysfunction, will be offered to participate in this study. Participants who agree to participate will be asked to sign a written informed consent. Information regarding their personal and family medical history will be collected via questionnaires. Medical staff will fill clinical questionnaires detailing patient clinical status prior to the study. Patients will be followed up to 4 months after initiation of treatment with Fampyra. Compliance to treatment will be assessed by collection of the empty vials of the medication. In each of the follow-up meetings evaluation of manual function, evaluation of ambulation and evaluation of general neurological function will be performed.

Exploratory Study to Assess Clinical Response to Gilenya® (Fingolimod) in Hispanics With RRMS
Multiple SclerosisGilenya (fingolimod) is approved for multiple sclerosis. However, it is unclear of its clinical effect in the Hispanics with MS given that clinical studies had limited representation of this population. It is also unclear if Gilenya would be as effective in individuals with disease predominantly affecting the optic nerve and spinal cord (OSMS) commonly seen in Asian populations. Objectives: To compare the clinical response of Gilenya® (fingolimod) in relapsing remitting OSMS and MS of Hispanic descent using ancestral markers as a biomarker of treatment response and clinical disease state.
