This Is MS Multiple Sclerosis Community: Knowledge & Support

.

This study has been mentioned before---but I thought it might be valuable to have it on this thread dealing with looking for ferritin as opposed to hemosidrin in CSF--

Here is a study from 1988 which utilized autopsy tissue--remember what Dr. Zamboni discussed in his Big Idea paper regarding hemosiderin as a bio-marker for CHRONIC venous disease--vs. ferritin as a marker for a recent venous infarction.


http://www.ncbi.nlm.nih.gov/pubmed/3346691

(I find it interesting that occasionally the control brains showed diffuse hemosiderin deposition and it was related to cardiovascular/cerebrovascular disease.)

Please note the area of the MS brains that showed the most iron deposition----it was seen in 1988 in this study, it is seen today in 2010 by Dr. Rohit Bakshi--
Substantia Nigra Pathology Predicts Disability in Multiple Sclerosis
Serial transcranial neurosonology in patients with MS reveals a possible link between substantia nigra pathology and progression of neurological disability.

Dr. Bakshi has just returned from a visit to the University of Ferrara, where he addressed how his ten years of research and Dr. Zamboni's research are coming together.

bump--since Dr. Embry mentioned this as a "negative" study--
my point is that it's a moot study, because ferritin in CSF is not a correct biomarker for chronic venous disease.

Hemosiderin is.

What is wrong with the watch analogy is it assumes deceit. If I am buying a cheap watch on the street that might apply. I take these gaffers' word until it is proved wrong. I guess it depends on your view of human nature, but IMO the last place to look for deceit should be in scientific journals. I first read the abstracts assuming honesty.

Cheer,

I viewed the discussion article in the front of Neurology journal which features a brief commentary on the research paper.

Quite interesting - the doctor quoted believes many of his MS patients are in fact anemic - inflammation in the brain causes elevated CSF Ferritin levels which mask the low iron levels when CSF Ferritin levels are tested. He advocated other tests to identify anemia and believes all MS patients should be tested this way.

One could summise from this that as some have speculated CSF Ferritin levels in MS patients are not necessarily the best indicator of whats going on.

It may also be a cautionary note against trying to reduce ones iron levels to combat CCSVI....

Of course, another way of expressing these results is that RR MS patients were more than twice as likely to have pathologic CSF levels than normal, PP MS patients were almost three times as likely and SP MS were a whopping 8 times as likely. Also, these pathological levels persisted over a three year period. On the positive side, to counteract the sting likely to be felt by those pinning their hopes on Zamboni, these same researchers have graciously announced that chocolate rations have been increased to 20 grams a day!!!

Scorp--not sure what those links were in reference to. If you were linking to pages stating that ferritin is a good biomarker? Not sure. In any event...ferritin in CSF is a great biomarker for stroke and a one time infarction, but not for an ongoing, chronic venous disease. Here's why:


http://www.ncbi.nlm.nih.gov/pubmed/7415809

It's the build up of ferritin over time that created the hemosiderin. Here's Dr. Zamboni explaining why--



Dr. Zamboni talked about this in Bologna...how hemosiderin was a terrific measure for iron deposition in chronic, ongoing venous disease. Not for a one time hit, like a stroke. He measured the hemosiderin in urine in chronic venous disease and in pwMS, and found the correlation.
hope this explains it better-

Right on!

Sorry Cheer it was getting late for me when I posted those links. I researched comments made by proponenets of Zamboni's study and it looked to me as if they were saying that ferritin levels were one way to measure iron in the body and high levels would help confirm Zambonio's hypotethsis. I do not see where Zamboni has ever said ferretin levels in the CSF is not a good biomarker for ongoing chronic venuous disease. I do see where he states hemosiderin is an important biomarker but I can not see where he stated that ferretin levels are generally irrelevant.

.

Lyon, as far as I can judge this, Zamboni always wanted and was open to work with the neurologists. (See, for example, his interview with ccsvi.nl.) Wouldn't it be a good, sensible approach to seek the in-depth dialogue, learn each others point of view, and THEN question each others methodology? This just seems reasonable to me. I can't understand why they don't even want to talk to him before trying to replicate his research. Even if it wasn't more than some sort of "know your enemies".

What's wrong with Zamboni charging money for his ultrasound detection method if he invented it? Like any other inventor, isn't he entitled to the fruits of his ingenuity? He might have been more clear, however, that using an ultrasound as a detection tool without proper training could lead to mixed results. He should have recommended a venogram or at least an MRV as detection tools for any replication studies. The margin of error associated with different methods of Doppler detection vs. venogram should have been established before it's use could be advised in replication studies.

Just stumbled over the study in the MSIF e-mail news of this evening and was wondering about the authors behind it. Great you already discussed it.

Below how the MS International Federation presented it in their e-mail news (and funny that this "interesting examination" was followed by an article of potential increased risk of cardiovascular disease - "but data are limited" they say). As we know the scientific committees in the MS associations are mainly composed of neurologists that choose the type and style of research summaries to be published... I have no other words for this "interesting examination" while there are far more other interesting ones related to the topic that could be mentioned!!

>>Normal CSF ferritin levels in MS suggest against etiologic role of chronic venous insufficiency

The authors conducted an interesting examination of CSF ferritin levels in patients with all sub-types types of MS and a range of other neurological disorders to investigate the role of venous stasis related parenchymal iron deposition in pathogenesis of MS. In MS patients, there was no significant change of CSF ferritin levels over the 3-year follow-up period. The data from this study therefore does not support an etiologic role for CCSVI-related parenchymal iron deposition in MS.

>>Risk of Arterial Cardiovascular Diseases in Patients with Multiple Sclerosis: A Population-Based Cohort Study

Patients with multiple sclerosis (MS) may have a higher risk of cardiovascular diseases (CVD) than the general population, but data are limited. Researchers from Denmark conducted a population-based cohort study involving Danish citizens diagnosed with MS (n = 13,963) from 1977 to 2006 and an age- and sex-matched population cohort (n = 66,407) and calculated the risk of arterial cardiovascular disease (CVD) for all subjects.

Adjusted incidence rate ratios at 1yr follow up and subsequent 2-30 year follow up for myocardial infarction (MI), overall stroke rate, heart failure and atrial fibrillation/flutter were calculated. In this Danish cohort, the risk of CVD among MS patients was low, but greater than that in the general population, particularly in the short term.
