🚨Another study finds #microclots in #LongCovid

“We would argue that whilst there may be many mechanisms at play in the pathogenesis of Long Covid, the common pathological process is thrombotic endotheliitis.”medrxiv.org/content/10.110…
“We conclude that presence of microclotting, together with relatively high levels of six inflammatory molecules known to be key drivers of endothelial and clotting pathology, points to thrombotic endotheliitis as a key pathological process in #LongCovid.”
“This may be characterized by the formation of anomalous fibrinaloid microclots, hyperactivated platelets, endotheliitis and elevated levels of prothrombotic inflammatory molecules which interact with each other as well as with platelets and the endothelium”
“Up to now, we have demonstrated significant #microclot formation & platelet activation in all #LongCovid patients whom we have studied using fluorescence microscopy”
“..as well as detailed proteomics analysis revealing several-fold increased concentrations of inflammatory molecules entrapped within the microclots.”
“Given the significant increase in the rates of thrombotic events following even a mild infection it is imperative that the thrombotic endotheliitis is treated urgently.

There is an immediate need for a microclot detection method that can be rolled out for clinical use.”
“We argue that such a microclot detection method together with the demonstration of relatively high levels of the six molecules described in this paper, would be good evidence for an ongoing thrombotic endotheliItis”
“The optimal therapeutic regimen is yet to be defined; however given the complex pathophysiology, such therapy is likely to incorporate antiplatelet drugs, as well
as agents acting on the enzymatic pathway of coagulation” #LongCovid
Absolutely amazing work #TeamClots@resiapretorius @dbkell @doctorasadkhan

You continue to lead the way, now it’s time for everybody else to pick up the slack !! Let’s GO!

“They discovered #LongCovid patients had 14 elevated biomarkers associated with blood vessels.”

"Our theory is the blood vessels are quite injured & they're trying to not only heal themselves, but they're also reaching out & trying to find healthy tissue” cbc.ca/news/canada/lo…
“The team is now working on developing a ‘point-of-care’ test to allow people to receive a diagnosis ‘very easily and very quickly.’ It could be used in urgent care clinics, family doctors' offices or off-the-shelf, said Fraser, who is also a professor at Western University.”
"The last estimate I saw in the US was 111,000 patients were being diagnosed daily, and that's based on clinical grounds."

"It's a significant problem and a growing problem." #LongCovid

“The findings add to mounting evidence that ‘something is going on’ in people who develop #LongCovid that makes exercise challenging, if not impossible, said Matthew Durstenfeld, a cardiologist at @ZSFGCare

“This is more than deconditioning.”washingtonpost.com/wellness/2022/…
“They harbored a raft of unusual, responses to exercise.. people’s muscles drew less oxygen from the bloodstream, hampering muscles’ ability to contract… heart rates also often failed to ramp up as much would be expected during exercise, slowing blood flow throughout the body”
“These are not common physiological reactions after someone has gotten out of shape because of illness and bed rest” #LongCovid

#LongCovid plagues 1 in 20 people more than six months after infection”

“A new study based on 100,000 participants provides powerful evidence that many people do not fully recover months after being infected” washingtonpost.com/health/2022/10…
“The Scotland Study, which included a control group, was able to pinpoint which symptoms were linked to covid.. those who had covid were significantly more likely to get 24 of the 26 symptoms.. for example, those who were infected were 3½ times more likely to be breathless.”
“Lindsay Polega of St. Petersburg, Fla., had covid three times and experienced symptoms for months after the most recent bout”

New #LongCovid study:

“Vascular transformation blood biomarkers were significantly elevated in #LongCovid, w/ angiogenesis markers (ANG-1/P-SEL) providing classification accuracy of 96%. Vascular biomarkers hold potential for diagnostics & therapeutics” molmed.biomedcentral.com/articles/10.11…
“In this study, we measured 16 vascular transformation blood biomarkers obtained from age- and sex-matched Long-COVID outpatients, Ward COVID-19 inpatients, ICU COVID-19 inpatients and healthy control subjects.”
“Our data indicate a unique #LongCovid blood proteome; two vascular transformation biomarkers were identified that distinguished Long-COVID patients from acutely ill COVID-19 inpatients and healthy control subjects (classification accuracy of 96%)”

"This is something the ivory tower medical profession needs to realize — #LongCovid is going to push us outside our comfort zone w/ illnesses we can’t define. Because we don’t like when we can’t understand something but we have to get over that" @WesElyMD statnews.com/2022/10/10/a-d…
"With long #Lyme, #MECFS.. I was taught in med school they weren’t real..I used to think those weren’t real. I was just with some med students last week, & I talked to them about long Lyme. And they said we were taught that that’s not real — and these are current med students."
The first thing I say to my fellow #MedTwitter is we’re busy.. I get that.. for #LongCovid, there’s no treatment yet, but you can say to them, “I’ll stick with you as we learn more in the months and years ahead and we’ll figure this out together.” - @WesElyMD

“Let’s spend 5 good minutes on something it seems our government doesn’t want to talk about.. 30 million adults in the US currently have #LongCovid.. 80% of them are having trouble just doing every day things — and I know because I’m living it”

Powerful segment from @ChrisCuomo
@ChrisCuomo: What worries you most?

@drwilliamli: That the message being sent out is that the pandemic is over, which is what people want to hear — yet it’s not — What we have to do is not focus on the acute infection.. but that 10-30% could get #LongCovid and we don’t know who
