Multiple Sclerosis Society of Canada vs. CCSVI: Has the MS Society missed the mark with Chronic cerebrospinal venous insufficiency

The battle over how fast and how much to put into the controversial treatment of Multiple Sclerosis is heating up.  Suffers of this terrible disease are  banding together and joining the fight.  There are demanding and rightfully so more research and quicker answers from the MS Society.

 
For the first time there seems to be at the very least a stop to the progression of this disease, maybe even a cure.  Today those who suffer from MS are left with few options when it comes to the treatment of Multiple Sclerosis, injections and complete uncertainty.
 
Ever since the Italian physician Paolo Zamboni procedure was released to the Canadian public there has been a groundswell of interest. The momentum is growing faster and stronger as suffers, family and friends of people with Multiple Sclerosis seek answers. 
 
Join the fight to change the direction the MS Society of Canada has taken and move toward a more open look at CCSVI.
 
Here is a great article at the Globe and Mail that all MS suffers should read.

Clinical effect of neutralizing antibodies: Multiple Sclerosis

Clinical effect of neutralizing antibodies to interferon beta that persist long after cessation of therapy for multiple sclerosis

Interferon beta (IFNb) is a first-line treatment for people with MS. However, increasing evidence suggests that the presence of neutralising antibodies during treatment is associated with a reduction in treatment efficacy. The authors of this study found that anti-IFNb neutralising antibodies could persist after treatment cessation and were associated with higher disease activity and poorer clinical outcome. Arch Neurol. 2010 Feb 8

MRI of the corpus callosum in multiple sclerosis

MRI of the corpus callosum in multiple sclerosis: association with disability

The corpus callosum is one of the most important white matter tracts in the brain and forms the major connection between the two cerebral hemispheres, being involved in the performance of complex tasks. The corpus callosum is one of the regions of the brain affected in MS, but its study by conventional MRI techniques has not been satisfactory. The authors found that abnormalities in the corpus callosum can be assessed with new quantitative MRI techniques and are associated with cognitive and complex upper-extremity dysfunction in MS. Mult Scler. 2010 Feb;16(2):166-77

Genome-wide Association Study: Multiple Sclerosis

Genome-wide Association Study in a High-Risk Isolate for Multiple Sclerosis Reveals Associated Variants in STAT3 Gene

MS is a complex disease of unknown cause where both genes and environment seem to have a role in its pathogenesis. The authors have investigated the impact that some specific genetic variants - recently linked to MS - have on the risk of MS, in an extensive group of people with MS and healthy controls in Finland. They found a specific genetic variant which had a protective role in MS. Interestingly this gene was found to have been previously associated to another autoimmune disease, suggesting a significant role of this gene in immune system and autoimmune disease pathogenesis. Am J Hum Genet. 2010 Feb 12;86(2):285-291.

IRM du corps calleux chez le patient atteint

 IRM du corps calleux chez le patient atteint de sclérose en plaques : association avec le degré d’incapacité

Le corps calleux est l’un des plus importants faisceaux de substance blanche du cerveau, il constitue la principale voie de communication entre les deux hémisphères cérébraux et joue un rôle dans l’exécution des tâches complexes. Le corps calleux est l’une des régions du cerveau touchées par la sclérose en plaques (SP), mais les résultats de l’exploration de cette structure anatomique au moyen des techniques d’imagerie par résonance magnétique (IRM) traditionnelles ne sont pas satisfaisants. Les auteurs ont découvert que les anomalies du corps calleux peuvent être évaluées grâce aux nouvelles techniques d’IRM quantitative et qu’elles sont associées à une dysfonction cognitive et à un dysfonctionnement complexe des membres supérieurs chez les patients atteints de SP. Mult Scler. 2010 Feb;16(2):166-77

Results of Phase II “CHOICE” Study Published

Results of Phase II "CHOICE" Study Published, Showing that Daclizumab Reduced Disease Activity in Relapsing MS, and Revealing Novel Immune Mechanism

230 people with relapsing MS taking interferon beta and having disease activity were administered one of two doses of daclizumab (Biogen Idec and Facet Biotech Corp.) or placebo - show that the higher dose reduced disease activity on MRI scans by 72% and the lower dose by 25%. Immune analyses show that this reduction was associated with a dramatic increase in CD56bright NK cells - an unexpected finding. Daclizumab is a laboratory-created monoclonal antibody that blocks the activity of interleukin-2 receptor-alpha, a key immune activator in MS. The drug is approved for use in organ transplant rejection. The Lancet Neurology, Early Online Publication, 16 February 2010

Les résultats de la phase II de l’étude CHOICE indiquent une réduction


Les résultats de la phase II de l’étude CHOICE indiquent une réduction de l’activité de la maladie sous l’effet du daclizumab chez des patients atteints d’une forme rémittente de SP, en plus de révéler un mécanisme immunitaire jamais observé auparavant

 

Au cours de cet essai clinique, 230 personnes atteintes d’une forme rémittente de SP, traitées par l’interféron bêta et présentant des signes d’activité de la maladie ont reçu soit l’une ou l’autre des deux doses de daclizumab (Biogen Idec et Facet Biotech Corp.) à l’étude, soit un placebo. Les clichés IRM réalisés dans le cadre de cet essai ont permis de constater que la plus forte des deux doses avait permis une réduction de l’activité de la maladie de 72 %, alors que la plus faible dose avait réduit cette activité de 25 %. Aussi, les analyses portant sur la réaction immunitaire ont révélé que cette réduction était associée à une augmentation importante du nombre de cellules tueuses naturelles CD56 de forte expression (dites CD56bright), ce qui constitue une observation inattendue. Le daclizumab est un anticorps monoclonal synthétisé en laboratoire dont l’action consiste à bloquer l’activité du récepteur alpha de l’interleukine-2 (IL-2), considéré comme un activateur clé de la réponse immunitaire dans la SP. L’utilisation de ce médicament a déjà été approuvée pour prévenir le rejet de greffes. The Lancet Neurology, version électronique publiée le 16 février 2010

Dr. Paolo Zamboni: Chronic cerebrospinal venous insufficiency (CCSVI) and MS (Multiple Sclerosis)

Chronic cerebrospinal venous insufficiency (CCSVI) and MS

 
Overview and FAQ
November 2009
 
"As President and CEO of the MS Society, I am aware of the tremendous interest across Canada and around the world caused by the recent news coverage of the CCSVI study. Indeed I share your excitement and hope in the preliminary findings of this study. I also celebrate and respect the integrity of our research funding programs which will continue to ensure that the very best projects are selected and supported. For more detail on this process please link here."
 
Yves Savoie
President and chief executive officer
President, Ontario Division
 
Overview
 
Chronic cerebrospinal venous insufficiency (CCSVI) describes a hypothetical disruption of blood flow in which the venous system is not able to efficiently remove blood from the central nervous system resulting in increased pressure in the veins of the brain and spinal cord which in turn results in damage to these areas.  Recent reports have revived the idea of an association between inadequate venous drainage and multiple sclerosis.
 
The MS Society of Canada is aware of recent reports on the subject of CCSVI that may open up new avenues of research including new therapies for MS.  While the early data shows promise, it is important to acknowledge that the concepts surrounding CCSVI and multiple sclerosis are still relatively new and requires replication and validation in much larger, well-designed scientific studies before they can be accepted as established.
 
The MS Society of Canada is closely monitoring all research related to CCSVI and will post new information on www.mssociety.ca
 
FAQ
 
1.  What is CCSVI?
Chronic cerebrospinal venous insufficiency (CCSVI) is a term used to describe a hypothetical situation in which the venous system is not able to efficiently remove blood from the central nervous system. It is stated that this is related to narrowing of small venous structures in the neck, chest and spine.
 
2. Why is there a sudden interest in CCSVI and MS?
Media attention and a few recent reports have revived speculation about a possible dysfunction of brain blood flow and/or drainage in individuals who have MS. In particular, one study involving 65 people with different types of MS compared with 235 people who were healthy or who had other neurological disorders, a robust relationship was found between having MS and signs of venous insufficiency – suggesting that blood drainage by veins may be impaired, contributing to nerve tissue damage. This study, by Paulo Zamboni, MD (University of Ferrara - Ferrara, Italy) and colleagues, was published in 2009. (J Neurology Neurosurgery Psychiatry. 2009 Apr; 80 (4): 392-9. Epub. 2008 Dec 5.)
 
The investigators called this venous obstruction “chronic cerebrospinal venous insufficiency” or CCSVI. The treatment status of the people with MS did not appear to influence whether they showed signs of CCSVI. The authors speculate that the abnormal venous drainage of blood back from the brain and spine might set off the inflammation and immune-mediated damage that is characteristic of MS.
 
3. Do these reports of a possible association between insufficient vein drainage and MS mean that MS is caused by venous insufficiency?
Not necessarily. Based on what has been published so far, we can only say that MS may occur in association with impaired venous drainage of the central nervous system. This impairment, if truly present, could cause MS but it is possible that it is incidental to the disease. More study is needed.
 
4.  How has CCSVI been treated?
Researchers involved with CCSVI have used “balloons” to open up narrowed veins or inserted stents into veins to help keep them open. This work is at a very early stage and has been performed on only a very small number of patients.  It requires passing a catheter (wire) through the veins to the area of venous narrowing so that it can be widened and is not without risk including the chance of bleeding or the formation of abnormal blood clots.
 
5.  Will the treatment of CCSVI be useful for the various forms of MS?
Whether this type of treatment will be useful in any form of MS is currently unknown as research on this question is at a very early stage.  Much more work needs to be done.
  
6.  What is the MS Society’s position on CCSVI?
The MS Society of Canada believes that this topic opens up new avenues of research in MS including the possibility of new treatments. Although the early data are of great interest, it is important to acknowledge that the concept of CCSVI as a cause of MS and the use of stents or balloons to widen veins as treatments, are ideas that are far from being accepted by most researchers in the field. The early results need to be replicated and validated in much larger well-designed studies.
 
The MS Society of Canada is closely monitoring all research related to CCSVI and will post new information on www.mssociety.ca.
 
7.  Does the MS Society currently fund research into CCSVI?
At the present time, the MS Society of Canada does not fund research into CCSVI but it is open to the possibility of funding appropriately designed studies that address this topic.
 
The MS Society of Canada welcomes research proposals from qualified investigators based in Canadian institutions whose research questions are relevant to multiple sclerosis. All proposals received are thoroughly evaluated by expert volunteer scientific peer review panels from major academic research institutions. Proposals are evaluated for their scientific merit and relevance to the field of MS. This same policy would apply to potential research projects on the topic of CCSVI and MS.
 
8.  Does the MS Society recommend people travel to get potential treatments related to this new idea?
The MS Society believes that this is a question to be addressed by the individual to their neurologist/physician. It is noteworthy that the treatment ideas in question are very new and not scientifically established.
 
9.  I have MS. Should I be tested for signs of CCSVI?
Please consult your neurologist/physician for medical advice on this topic.
