So, back to ferritin levels in CSF--as stated earlier, ferritin is an appropriate bio-marker for an acute hemorrhage in the brain. We find ferritin in the CSF of those with stroke.
The doctors in the study alluded to the fact that those with stroke or infarction had elevated ferritin. This is because ferritin is elevated right after the infarction, until the body is able to clear it. Or, if it is not able to clear it, the protein changes to hemosiderin.
Dr. Zamboni has never tested ferritin levels in CSF, nor has he ever written about this. As a vascular doctor, he has not tested CSF. He uses blood and urine.
What he has written about is an easy, cost-effective test for iron binding proteins. A urine test for hemosiderin.
From the Big Idea: Iron Dependent Inflammation in Venous Disease
Erythrocytes are degraded by the interstitial macrophages, with the released iron incorporated into ferritin. Over time, with increasing overload of iron, the structure of ferritin changes to haemosiderin.
Iron overload in MS plaques has been demonstrated in vivo by MRI.28 In addition, we observed haemosiderin in the urine of patients with active inflammation of MS
Dr. Zamboni is not holding on to some secret protocol. He is a vascular doctor, and speaks to changes in the vasculature he sees in chronic venous disease. He tests blood and urine. It was a group of neurologists that determined they could prove or disprove CCSVI by testing for ferritin in CSF....while there is nothing in any medical literature to link ferritin to chronic venous disease, or to Zamboni's studies.
