Scientists now understand the mechanism that leads to platelet activation and clotting.
A new lifesaving treatment for people suffering from vaccine-related blood clots has been demonstrated by scientists at McMaster University.
Researchers at the McMaster Platelet Immunology Laboratory (MPIL) are recommending two treatments, a combination of anti-clotting drugs with high doses of intravenous immunoglobulin, to combat vaccine-induced immune thrombotic thrombocytopenia (VITT).
The treatment’s effectiveness was described in a report describing three Canadian patients who received the AstraZeneca vaccine, and who subsequently developed VITT. Two suffered clotting in their legs and the third had clots blocking arteries and veins inside their brain.
“If you were a patient with VITT, I’d be telling you we know of a treatment approach. We can diagnose it accurately with our tests, treat it and we know exactly how the treatment works,” said Ishac Nazy, scientific director of the lab and associate professor of medicine.
“Our job is to understand this disease mechanism so we can improve diagnosis and patient management. This study brings together successful lab diagnostics and patient care. It’s a true translational medicine approach, which is really our forte, bench-side to bedside.”
VITT occurs when antibodies attack a blood protein, called platelet factor 4 (PF4), which results in activation of platelets in the blood, causing them to clump together and form clots. Blood samples taken from the patients after treatment showed reduced antibody-mediated platelet activation in all cases.
While the study patients were older, many VITT cases have affected younger people. However, Nazy and his MPIL colleagues said VITT is a rare disorder, regardless of people’s age.
The lab’s scientists include professors of medicine Donald Arnold and John Kelton and professor of pathology and molecular medicine Ted Warkentin. Together they devised an effective VITT test and treatment by building on their previous investigations of heparin-induced thrombocytopaenia (HIT).
While the two conditions are similar, using a standard HIT antibody test to detect VITT can yield false negative results.
This led the scientists to modify the HIT test to detect VITT-specific antibodies that are found, albeit rarely, in patients who had a COVID-19 vaccine.
Subsequent lab tests on patient blood samples showed how high doses of immunoglobulin coupled with blood-thinner medications shut down platelet activation and stopped clot formation.
“We now understand the mechanism that leads to platelet activation and clotting,” said Nazy.

Times have changed, eh?
I like my plan better. The preventative measure of no covid vaccine.
Just give us your credit card.
“ Together they devised an effective VITT test ..”
I have been talking about the need for such a test for weeks/ months on FR and now it’s (almost) here. Kudos to the scientists for heeding my call.
They don’t just want your money.
They want your life, too.
Maybe a Nobel Prize or two...................
Works for me......................
“vaccine-induced immune thrombotic thrombocytopenia (VITT.)”
The good news. There will be an ICD-10 Diagnostic Code to keep track of this pathology.
So a vaccine to fix the damage caused by a vaccine?....
If you do not take the chinese virus vaccine then these are the survival rates:
CDC Covid-19 Survival Rates as of 10/2020
Age 0-19 — 99.997%
Age 20-49 — 99.98%
Age 50-69 — 99.5%
Age 70+ — 94.6%
Why risk death or being crippled and having your life shorten?

Why did that old kids song about the old lady swallowing the fly suddenly pop into my head?
Ideally people who fail the VITT test should avoid the vaccine altogether, imo. Why risk complications by taking ‘treatment’ for VITT ?
The good thing about VITT is that the number of people it affects is very very small compared to the general population and if a sufficient number of people in the general (non VITT) population is vaccinated, they can cover for the minority of unvaccinated people and we can still reach herd immunity.
“ Maybe a Nobel Prize or two..”
Indeed why not. This is very significant.
I already take an atiplalet drug since I had a Stent two years ago. This further confirms my decision to never take the vaccine.
Refusing the vaccine?
That’s MY solution...............
4. If this works with the vaccine. Will it also work with clotting from the virus? or is that a different mechanism?
