1/ 🧵 What’s in a name? ‘Long Covid’ ‘post-acute Covid syndrome’. What does that make you think of? Tiredness? #longcovid is covid related THROMBOTIC VASCULITIS. Sounds serious, right? ✅ 🤷🏻‍♀️
2/ thrombotic vasculitis is when the spike protein makes your blood vessels inflamed and form little clots that block small blood vessels 🩸 #MicroClots I like evidence so here you go portlandpress.com/bioscirep/arti…
3/ when your blood has little clots in it filled with amyloid it causes more Inflammation. Think of when you get a cut and the skin goes red and sore. That’s inflammation. Imagine that in your blood vessels. The oxygen in your blood then struggles to get to all the tissues. 🩸 🤒

#SíndromePulmónRiñón: Ayudas diagnósticas
Radiología: infiltrados con patrón alveolar de distribución simétrica, predominio central y en bases pulmonares; sin embargo, hay casos en los que los hallazgos pueden ser focales – unilaterales y discernir con otras entidades puede ser difícil.
Gasimetría arterial: hipoxemia (PaO2 menor de 60mmHg); el mecanismo de esta condición es secundaria a “shunt” y alteración de la difusión, lo que explica la pobre respuesta al oxígeno a alto flujo en la mayoría de los casos.

So excited to watch this interview between @polybioRF s @microbeminded2 and @MS_SouthNassau’s @RuhoyMD that I’m going to live tweet it. Dr. Ruhoy is a neurologist with a Ph.D in environmental medicine who works with #longCOVID #mecfs #EDS patients.
Ruhoy describes her long-standing interest in integrative medicine, natural approaches, and environmental medicine. She’s even a certified medical acupuncturist! She now helps lead a neurosurgery practice. 😍😍😍
Ruhoy: “I was an environmentalist from when I was very young and I believe that the world around us plays a role in our health. Even before I was a doctor, I would always try to find ways of living a healthier life. I saw no reason why I couldn’t combine it.”

IMPORTANT 🇮🇹 study🔴 -> "Vascular uptake more marked in the examinations of the patient who developed #longCOVID. These findings suggested that vascular inflammation and its duration are responsible for the clinical course of the disease and the development of long COVID."👇
This matches with @MartaEsperti and @JasmineHayer documented cases.
#Vasculitis-like explains at least a subset of #longhaulers?
In which extense this can happen also in other organs and especially brain?

It's #tweetorial time! Read on for a #medthread on:

Cutaneous Small Vessel #vasculitis (CSVV)!

#MedEd #FOAMEd #dermtwitter #dermatology #medtwitter #rheumtwitter pc: @dermnetnz
1/
I've heard different ways to organize the vasculitides over the years, but by the far the most common is by vessel size. As a #dermatologist, I see the small vessel vasculitides most often, so we'll focus on that today. Yes, Takayasu's important, but I'll save that for later!
2/
There is a relatively limited list of possible diagnoses with CSVV. I've included the most common below.

The blue I lump together as they are similar, and biopsy results help you differentiate.
The red are the ANCA-associated.
The green are the unique ones.
