On one of Jean Beale's threads at CCSVI in MS on FB we were discussing the outcome from Kuwaits study and at the same time I had been discussing David Wheldon's findings (
http://www.davidwheldon.co.uk/ms-treatment1.html ) with his wife's MS with Paul Thibault a researcher, Phlebonist and Dr in Sydney Australia.
The communication I had with Paul was about the viral effects (or BBB crossing effects) and what effect that will have on PTA outcomes and MS outcomes from PTA, which IMO are two totally different things when you must consider that there are two parts to the CCSVI involvement in any of these many disease outcomes caused by CCSVI.
From my FB site
"CCSVI in New Zealand
A quote from Paul Thibault about the outcomes in PTA and breach of the BBB during a recent conversation where coincidentally we identified that a virus 'CPn' is chronically active in my system and may be the cause of my MS and CCSVI symptoms;
"Regarding your thought above. The CPn intracellular bacteria affects both the lining of the veins and from there spreads to the surrounding nervous tissue. This is the reason why the MS lesions are predominantly around the veins as shown by a number of pathologists explaining the peculiar distribution of MS lesions. Whilst Schelling attributes this to mechanical effects of "back-jets", I favour an infective causation spreading along the veins to involve the neural tissue, as I believe epidemiological evidence favours this pathogenic mechanism. Schelling rightly criticizied the concept of infection, but he assumed that infection would spread from the arterial side of the circulation which it does in general with viral (eg EB virus) infections. But gram -ve intracellular pathogens such as Cpn (and spirochetes (Lyme) to a lesser extent) can spread by the lymphatic system and veins. I also check for Chlamydophila trachomatis as I suspect this may be involved in a smaller subset.
Cpn is widespread throughout society as a common respiratory infection and most people will come into contact with it at some time. Why only a very small proportion develop MS is unknown, but may be related to Vitamin D levels at the time of initial infection and other unknown factors. Kurtzke predicted this with his extensive epidemiological studies and he favoured the idea that it was mainly one infective agent, rather than a larger number.
The reliability of the NAC test is yet to be determined and I am accepting David Wheldon's opinion on this. It would certainly make an interesting study. The article I would recommend you to read is:
Kurtzke JF. Epidemiologic evidence for multiple sclerosis
as an infection. Clin Microbiol Rev 1993;6:382–427
The endothelium of the venous wall is part of the BBB. Any infection of this layer is going to affect the integrity of the BBB"
So in my opinion the outcomes from PTA need to be looked at thoughtfully. If a bacteria has crossed the BBB then it will require identification and treatment before the real outcome of PTA can be seen as an individual part of a process of correcting the whole effect of CCSVI and BBB leakage.
