Filter by:This is a study evaluating the effect on brain volume of daily glatiramer acetate (GA) and add-on pulse steroids.
This open-label extension study will evaluate the long-term safety of glatiramer acetate and its effect on the neurologic course of participants with relapsing-remitting multiple sclerosis (RRMS). Participants have scheduled visits every 3 months to assess glatiramer acetate safety and their Multiple Sclerosis (MS) status.
Randomized study designed to look at the difference in relapse rates between patients remaining on their current interferon medication and those switched to Copaxone®
This is a study to test if a new higher dose of Copaxone is more effective in treating relapsing-remitting multiple sclerosis than the currently available 20 mg dose.
This is a 10-week, randomised, double blind, placebo-controlled, crossover trial to investigate the effect of Cannabis Based Medicine Extract (Sativex) on patterns of brain activation associated with movement in 20 MS patients suffering from lower limb spasticity. Spasticity is a common symptom in Multiple Sclerosis (MS), occurring all over the course of the disease, particularly in the progressive phase.Physiologically, spasticity and hyperreflexia habitually seen in patients with pyramidal syndrome is due to lesions of other descending pathways, such as the cortico reticulospinal pathways, which participate in voluntary movements.It is now known that an endocannabinoid system acts in humans by at least two types of cannabinoids receptors, CB1 and CB2. There is evidence to support the view that the psychoactive ingredient in cannabis, delta 9-tetrahydrocannabinol (delta 9-THC), and cannabinoids in general, can reduce muscle spasticity in people with MS. Aim of the study will be to evaluate the effect of Sativex on: (i) patterns of brain activation associated with movement (fMRI) in MS patients suffering from spasticity; (ii) changes in level of spasticity (H-reflex); (iii) changes in intracortical excitability and on synaptic intracortical network of the motor areas (double shock TMS).
The frequency of auto-immune diseases (including multiple sclerosis) is increasing in industrialised countries. According to an hypothesis which is receiving a wide international credit, this may be due to the fact that the populations of these countries are increasingly less exposed to microbes further to the improvement of hygienic conditions and to the use of antibiotics. If exposure to microbes is lacking, also their regulatory function is missed with a consequent possible onset of auto-immune symptoms. For this reason, it is deemed that by exposing the immune system of a patient to an ancient microbe, being complex and important in man evolution, like the Tuberculosis Mycobacterium, it is possible to rebalance the immune system.
Cerebellar disorders are often disabling and symptomatic therapies are limited to few options that are partially effective. It seems therefore appropriate to search for additional approaches. Purkinje cells are the sole output of the cerebellar cortex: they project inhibitory signals to the deep cerebellar nuclei (DCN), which have a critical role in cerebellar function and motor performance. DCN neurons fire spontaneously in the absence of synaptic input from Purkinje neurons and modulation of the DCN response by Purkinje input is believed to be responsible for coordination of movement. Recent evidences support the notion that an increase in DCN excitability may be an important step in the development of cerebellar ataxia and point to the underlying molecular mechanisms: the inhibition of small-conductance calcium-activated potassium (SK) channels, that causes an increase of the firing frequency in DCN, correlates with cerebellar ataxia. The rationale of the present project is that SK channel openers, such as riluzole, may have a beneficial effect on cerebellar ataxia. The researchers propose to perform a pilot study investigating safety and efficacy of riluzole, an approved treatment for amyotrophic lateral sclerosis, as a symptomatic approach in patients with chronic cerebellar ataxia.
Clinical and experimental evidences suggest that there is a variability in therapeutic response to immunomodulating therapies in Multiple Sclerosis patients. Microarrays is a technology that permits to monitor the expression levels of thousands of genes at a time. The specific aim of this study is to identify predictive factors of therapeutic response in MS patients treated with high-dose Interferon-Beta.
The effects of routine rehabilitation in MS patients versus no rehabilitation.
Therapeutic strategies for multiple sclerosis (MS) are essentially based on the use of immunomodulatory agents such as interferon b and glatirmere acetate, but their efficacy is quite limited, they are not well tolerated and they have a very high cost. Recent works showed an immunomodulatory effects of HMG-CoA reductase inhibitors (the so-called "statins"). In experimental allergic encephalopathy, a murine model of MS, statins inhibit the onset and progression of the disease through a shift from Th1 towards Th2 cytokine production. Other in vitro studies suggest the ability of statins to inhibit the lymphocyte migration through the blood brain barrier. Furthermore, in an open labeled human study in MS, statin regimen was associated with a decreased lesional activity assessed by MRI. Statins are well tolerated drugs, used for many years, with a low cost and with a putative efficacy in MS. The investigators suggest to test the pravastatin safety and efficacy on MRI criteria in a double-blind, placebo-controlled study in 40 patients with a relapsing-remitting MS.
