Dr Paul Thibault - current position on CCSVI

From CCSVI / CCSVO specialist Dr Paul Thibault :

The concern I have is that people (medical doctors, patients, and the general public) will become disillusioned by the many studies (including Zamboni et al), which refute the use of venoplasty to achieve a "cure" for MSi. Zamboni has highlighted the connection between MS and a chronic venous disease, which I appreciate. However, since 2011 I have suspected his theory that venous obstructions cause demyelinationi (due to iron-deposition which accompanies vascular reflux) to be incorrect.

In a published pilot study (1), we showed that venoplasty appeared to improve cerebral perfusion and I feel this is the mechanism which explains why some pwMS experience symptomatic improvement following venoplasty. But this effect was short term in most, and only occurred in approximately 30% of those treated. We analysed 2 pilot studies in NSW, one at St Vincents Hospital and a later one at Prince of Wales Private Hospital. Both came to the conclusion that venoplasty was generally ineffective in improving the symptoms of pwMS in the long term. The major participants had no enthusiasm for publishing negative results from pilot studies, and no randomised placebo controlled trials were planned. We abandonded venoplasties for CCSVO (Chronic CerebroSpinal Venous Obstruction) in MS in 2012. At that stage, we had performed over 200 procedures. Never-the-less, the objective diagnostic ultrasound examination (2) that we developed to diagnose obstructive venous disease in the neck veins (in contrast to the subjective Zamboni ultrasound) appeared to be accurate, reproducible and indicated that the venous obstructions were due to a chronic inflammatory venous condition that resulted in obstructions to both the internal jugular veins AND the vertebral veins. Interestingly, the vertebral veins have been largely ignored by Zamboni and others - perhaps because they can't be treated by venoplasty. After seeing David Wheldoni's website suggesting that a chronic persistent chlamydophila pneumonia infection was the likely cause of disease in a large sub-group of pwMS, I developed the theory that MS was due to a chronic infective cerebrospinal phlebitis and venulitis (published in Phlebology in 2012.) (3). From that time, we have treated pwMS with the combined antibiotic protocol developed by the Stratton group (Vanderbilt University, Nashville) and David Wheldon. My observations are that the results have been superior to venoplasty, particularly in RRMSi with positive serologyi to Cpni, with relapses completely suppressed and only rare instances of new lesions developing on MRI examinations. Our 6-month follow-up with ultrasound flow measurements in the affected neck veins (published in Phlebology) shows significant improvements in those with positive serologyi testing to chlamydophila pneumonia (Cpn) infection. This article also highlights the possibility that chronic persistent infection with Cpn is widespread in the community but only a small percentage go on to develop MS. Some other factor, such as a genetic or concurrent infection with an agent like EBVi, is likely to be involved at a critical time early in life. Therefore CCSVI (O) is likely to be observed in many "normal" people who are included in randomised trials, which explains why so many studies have shown that the neck vein obstructions are observed in the "normal" population, but generally not at the rate found in pwMS. This is consistent with the epidemiology studies of the most famous MS neurologist, Prof John Kurtzke who concluded that MS was caused by an infection that was widespread through the community, but only a SMALL proportion went on the exhibit MS.

So why do some people have such a good result with venoplasty alone? I suspect that they have a "burnt-out" Cpn infection, that has been completely controlled by their immunei system, but has left resultant venous obstructions that cause reduced cerebral perfusion. These people test negative to Cpn. This state will be improved by successful venoplasty. As for the other > 90% who have chronic persistent Cpn infection but don't have MS, they will be prone to other vascular and "auto-immune" disease including coronary artery disease, cerebro-vascular diseasei, thyroid disease, CFSi, polymyalgia, reactive arthritis, thrombo-embolic disease, rosaceai and possibly lymphomas of the head and neck. PwMS have a high co-morbidity with these diseasesi.

So this is why I have entered into this argument, as the only doctor in Australia with a real interest in investigating the association of MS with CCSVO. I will be presenting the evidence at the UIP 2018 meeting to be held in Melbourne in February in a special "Masterclass on CCSVO". There will also be a demonstration of our Objective Ultrasound Examination, which will show that this is a real entity that needs to be addressed. I apologise that this reply has been so long, but it is an extremely complex problem.
