BACKGROUND:
-Vitamin D deficiency in humans is frequent and has been associated with inflammation. The role of the active hormone, 1,25-dihydroxy-vitamin D3 (1,25-VitD3) in the cardiovascular system is controversial. High doses induce vascular calcification; vitamin D3 deficiency, however, has been linked to cardiovascular disease as the hormone has anti-inflammatory properties. We therefore hypothesized that 1,25-VitD3 promotes regeneration after vascular injury

I am trying to interpret this but I read it as being only the valves themselves ("the defective cusps") that had zero endothelial cells, while the internal jugular vein walls had "significant derangement of the endothelial layer." The endothelium is deranged but present, in the walls, and not present, in the valves? This would be important, because a deranged enthothelium in the IJV walls might heal once the flow is normalized, but entirely absent endothelium would not recover -- or would it?The internal jugular veins' wall showed a significant derangement of the endothelial layer as compared to controls. Surprisingly, no endothelial cells were found in the defective cusps, and the surface of the structure is covered by a fibro-reticular lamina.

What this study was showing was that by supplementing 4,000 IU of vitamin D--the endothelial cells in humans functioned better. That's all. Supplementing 4,000 IU of D3 improved endothelial health in humans.
Endothelial dysfunction exists. It causes blood vessels to function sub-optimally. There is much that can be do to improve blood vessels. Mineral balance is essential...Arne is right to stress Mg, Jimmy stresses zinc. Vitamin D, when balanced in the human body (via UV rays or a moderate oral supplementation) really does help.
I'm just thankful that finally the CCSVI community is seriously studying the endothelium. And as a vascular doctor, Dr. Zamboni has the tools and skills to do this.

Endothelial cell death is pretty serious dysfunction.

Then why not come out and say it? "present findings suggest" is not very positive, yet, if the suggestion is true, then calcitriol is a very effective treatment for hypertension in renal malfunction. What other forms of hypertension does it treat, by its action on the endothelium?CONCLUSION:
In vivo and in vitro activation of VDR with calcitriol improves endothelial function by normalizing the expressions of AT(1)R and radical generating and scavenging enzymes and thus preventing ROS over-production. The present findings suggest that calcitriol is effective in preserving endothelial function in hypertension.
Would that not depend on what cause it to be missing, presumably the same thing that caused its derangement elsewhere? If calcitriol is effective in protecting endothelium from some kinds of damage, will it protect valve cusps, and perhaps help allow their endothelium to be restored in CCSVI?Cece wrote:cheerleader wrote:Dr. Zamboni recently discovered that the veins and valves of pwCCSVI do not have ANY endothelial cells. http://www.ncbi.nlm.nih.gov/pubmed/24972760I am trying to interpret this but I read it as being only the valves themselves ("the defective cusps") that had zero endothelial cells, while the internal jugular vein walls had "significant derangement of the endothelial layer."

My understanding of Calcitriol pulse plus raising Vit D3 blood level also impacts the immune system (see Prof Hayes work posted by SqueakyCat in D3 thread). Personally I would try this if an effective pulse dosage of Calcitriol in humans was known.PointsNorth wrote:Perhaps using a large pulse dose of Calcitriol followed by D3 for affected IJV/valve?

I am wary of any treatment whose benefits go away after such a short time. I am not likely to take Calcitriol or megadoses of D3, if it is not much less temporary than baclofen in its effects. The last thing I need is another symptomatic treatment that requires a lifetime prescription. D3, if it were all that was needed, is at least cheap.All improvement was lost after discontinuing D3 for 1 week.
