1/🧵🎥 How do “Dominoes of life” fall in critical illness⁉️
A pt arrives awake & talking but vomiting. In just 8 hrs he nearly dies of sepsis 🤯
Lung & kidney failure, heart attack, coma.
How can this happen & can we save him?
This🧵can help us understand the “arc of illness”
2/ His disease is Ascending Cholangitis
A gall stone lands in his common bile duct
📍Pain & vomiting
📍He’s admitted to the ICU
📍GI performs an ERCP to place a stent, bypass the stone, drain pus & control the source of sepsis
📍Add fluids & antibiotics
📍But he gets worse
Why?
3/ We bypassed the septic source (stone) & drain the pus, but dominoes were already falling.
Bacteria had gotten into his blood.
Too much inflammation & capillary blood clotting occurred, just like in COVID.
What happens when “cellular” dominoes start to fall uncontrollably?
4/ Our bodies can’t work well without blood & O2.
His BP dropped (shock) & didn’t perfuse his vital organs, so his heart, lungs, kidneys, brain went down.
CXR👇shows a catheter in his heart to measure pressures.
NOTE: Not everyone so sick needs a ventilator (no ET tube on CXR)
5/ We found his “WEDGE PRESSURE” initially to be >20mm Hg, which is very high & indicated his shock was not purely septic.
Indeed, his Troponin peaked at a whopping 77.
A heart cath showed clean coronaries.
This was a stress-induced heart attack, not blocked arteries.
6/ Here is a good one-pager to learn about the Swan Ganz Catheter and right heart catheterization.
It’ll tell you what different measurements mean.
In his case, we used norepinephrine, vasopressin, sedation with dexmedetomidine & a little fentanyl.
7/ While he was in multi-organ dysfunction…
☑️ Our focus on the #A2Fbundle kept #humanism at the forefront of our game plan
☑️ Awake/alert, light sedation, mobilizing, family
☑️ We kept his daughter at the bedside
☑️ She helped him through a 48-hour period of #delirium
8/ Sepsis care today is very different than 20 yrs ago.
We improved it but then COVID brought antiquated practices like deep sedation & immobilization.
This man’s family advocated for him. Please do the same for your loved ones.

Spiritual Rounds - 2 weeks following ICU discharge, I went to find my patient recovering ❤️🩹 from his sepsis.
He taught me all about the power of acceptance & being spiritually grounded. What a beautiful man. I thought I’d help him, but he helped me way more as usual.

🔸Let’s Unpack @NEJM
🔸Hear from patients
🔸We call LC a disease state
🔸It’s a clinical definition
🔸Adding Inclusion/Exclusion Criteria to our @theNASEM definition fosters great research definitions
🔸 I admit my early mistake…
“Long Covid is an IACC occurring after SARS-CoV-2 infection & present >=3 months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems.”
Read caveats in text box…
3/ Patients describing Long COVID – read text box
“My long Covid life remains terrifying. Last weekend I washed my car, dried it, put it back in the garage. Then I got violently sick and could hardly get up to get food. I was unable to read or even call my mom. I’m a shell of myself. But my physical issues aren’t half as bad as my brain problems. It’s hard to describe. You can say brain fog, but that doesn’t come close to doing it justice.”
“At work my brain is just begging for rest. I struggle with finding words and completing tasks in a timely manner. … I’ll be in a meeting and know exactly what I want to say before I say it. …I’ll get to a word, and I just cannot think of the word. I’ll just be like, ‘Give me a moment,’ and I’ll go through my brain cycling through words. This week the word was “consistent.” I couldn’t think of the word consistent. I kept thinking it was coincident or concentric or constant. I used to build prototypes multiple days a week, and now if I do anything in the lab, I’m pretty much wiped out for a week. …I mean, I’ve had to dig real deep. How much longer will I feel like this? I’m scared.”
2/ Tryptophan is an essential amino acid - we don’t make it.
So if we’re “programmed” to absorb ⬇️ from our diet, we sleep poorly, think worse, and all sorts of other bodily functions go awry.
Will SSRI & SNRI meds help, or anti-virals, or immuno-modulators?
Trials will tell.

This study by @maayanLevy_lab is a marvel of dozens of avenues of science that all point to a greater understanding of the realities of #LongCOVID as a chronic disease state.
Through work like this, we legitimize not only LC, but also #MECFS #LongLyme etc & take one step closer to finding medical solutions for past & future post-infectious states + syndromes like #PICS
1/🧵Catatonia - shocking & hopeful insights into a mysterious neurological disorder 💥
Did Oliver Sacks’s Catatonic “Awakening” Patients have a treatable Autoimmune Disease?
Here I unpack story & science from a stunningly well-done @WashingtonPost article
2/ Amazing Discoveries of Autoimmune Disease causing Decades of Catatonia, Schizophrenia
Autoantibodies and treatment with immunosuppressive medications are waking some patients up with crazy cool results. Here’s the article and my highlighted excerpts:
3/ “The first conclusive evidence was in her bloodwork: It showed that her immune system was producing copious amounts and types of antibodies that were attacking her body. Brain scans showed evidence that these antibodies were damaging her brain’s temporal lobes, brain areas that are implicated in schizophrenia and psychosis.”
📌 I didn’t think #MECFS was real till #LongCOVID opened my eyes
📌 It’s “mysterious” & we weren’t taught it in med school
📌 Yet 1,000s are suffering a disease traditional medicine doesn’t understand
📌 Let’s find answers
2/ Long COVID is estimated at 6% of US Population… @CDCgov
“Prevalence of #longCOVID among U.S. adults ≥18 ⬇️ from 7.5% during June 2022 to 6.0% during June 2023.”
More than 1 in 4 w LC have activity limitations, ie, it’s a LIFE altering disability.
📌A picture is emerging
📌It’s not pretty
📌Most pts w months-long symptoms aren’t recovered @ 2-yrs
📌The cluster including neurocognitive & cardiovasc symptoms is ominous
📌These data fuel trial design
2/ This Lancet investigation of just over 500 patients is not particularly large but is well done. The methodology used LC patients from Catalonia Spain from 3/2020 to 2/2022.
They included people who were unable to obtain Covid test but who had an acute onset of symptoms extremely consistent with the syndrome and who developed the same long-term definition of long Covid.
Some may argue about this point but the longCovid community has taught me how important these patients are to include in such research.
3/ Looking at this figure you can see the heat map emphasizing symptoms in clusters B & C that the authors are most confident indicate persistence.
📌Include ~340k COVID patients vs ~7M controls out to 2 yrs
📌Organ dysfunction persists in 33%
📌Levels of disability from #LongCOVID exceed those of cancer & heart disease‼️

2/ Remember that these data complement the 8 or so other studies showing similar findings, and EXTEND the information using VERY large control groups w censoring if those controls got COVID.
✏️Thus, older and more white than the average #LongCOVID person
✏️They also do NOT help us with Delta and Omicron variant COVID
✏️These findings are robust and statistically sound and published by very astute and qualified investigators
✏️But they must be extended scientifically in cohorts that include a high number of younger women, people of color and lower SEC as well as newer COVID variants.
