In the search for causes of multiple sclerosis, one cause has been the topic of much debate and skepticism and that is the chronic cerebro-spinal venous insufficiency or CCSVI. This large medical term is a condition in which the central nervous system is drained by a compromised blood flow to the veins. This condition and the term were first brought to light by an Italian researcher in 2008 named Paolo Zamboni. He believed that this condition played a direct role in the incidence of multiple sclerosis.
Many people in the medical community do not believe this and it has become a topic of debate among MS researchers; however, it has not stopped the researchers from considering the link and investigating it further. The biggest factor standing in the way of this research is the inherent danger of testing for CCSVI.
Studying CCSVI
In order to study CCSVI, researchers honed in on people with MS who also had been identified as having CCSVI. One such study, a small group of fifteen patients with both conditions, showed that there are several human antigens that are present in both conditions. Another study showed that patients with CCSVI and MS had an almost double rate of these antigens and variations than the control group did; however, the same study found that one particular gene variation that is present in MS does not appear in CCSVI in any of the instances. This simply leads to more questions than answers when it comes to the correlation between the two conditions.
The one thing that has been determined is that much more research is needed. Some studies indicate that CCSVI is not a cause of MS but may play a role in the condition of many people with multiple sclerosis. People who have MS and want to know more about this research and its implications should follow the reports closely. Some of the recent information is presented here to help get MS patients on board with what is known and what is occurring in this important area of research.
First and foremost are the methods used in determining if CCSVI is present in a person. There must be a best practice put in place and adhered to simply to prevent putting a person in any danger from the testing and to ensure that all tests are handled in the same manner so that results are not challenged.
In their efforts to move research forward and create a best practice, researchers are focusing on key areas such as:
- The best method of imaging CCSVI and how to best implement it.
- The reasons that CCSVI appears more often in people who have a progressive illness.
- Understanding the correlation between what is found on ultrasounds and what a normal variation is and what venous insufficiency is in relation to this.
- The reason that CCSVI is present in children.
- How MS and CCSVI are related in other facets of the disease such as its duration, MRI results and the progression of the disease. The condition will be compared to MS without CCSVI and CCSVI without MS and a relationship determined.
Researchers will use their answers and ideas to these areas to help plan a best practice for diagnosing CCSVI and thus pave the way to finding how the two conditions are related.
Research on the Effects of Treating CCSVI
If the research on CCSVI and its relationship to MS prove to be successful, the next logical step is to determine if treating the blocked veins would be beneficial or detrimental to MS patients. This is one area that has been the topic of many debates, as the treatment of blocked veins can often be dangerous. Researchers and scientists will have to find the answers to many questions including:
- What risks are associated with the procedure to unblock veins?
- Does treatment of CCSVI have a positive effect on all types of multiple sclerosis?
- Is the treatment permanent and if not how long will it last?
- Do the benefits outweigh the risks? Is the treatment reliable?
- Is treatment of CCSVI more beneficial than common therapy being used to treat MS?
Like the answers to the questions in the first phase of research, the answers to these questions will help determine if CCSVI treatment is effective in patients with multiple sclerosis.
There are many agencies receiving funding grants to continue these studies and many more patients with multiple sclerosis watching the medical news in hopes of finding that science has found an answer to their pain.
Scientist and doctors around the world are diligently working toward finding more treatment options for patients with MS. Many of them have placed their hope in CCSVI and treating it in order to treat MS. Until more research is conducted, MS patients will have to watch and read in order to stay abreast of the results.
