COVID-19 Daily Posts Summary & Microembolism Part II

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

I created this site in 2018 with the first post published 24th April 2018. My ambition for this site was, and still is, to be a placeholder for links and thoughts I find interesting related to emergency medicine (inspired by other similar sites such as EMCrit, LITFL, and the Swedish site STAIRS). I want this site to be an open node in space, adding to the rich culture of FOAM (Free Open Access Meducation) that exists online and, if it gets any traction, also being part of the online conversation of best practices in emergency medicine. However after the first post life – as it often does – had me prioritizing other projects in my life.

Until now.

Fast forward about twenty months later and enter the COVID-19 pandemic that has changed everything. When COVID-19 had us preparing for hell at my hospital in Stockholm, I then decided to write daily, I started the first daily post on 25th Mars 2020, with the aim to, again, organize links and resources and write down some of my thoughts on the emergency medicine aspects while trying to track the daily numbers of COVID-19 deaths both locally and globally.

It’s now twenty five days later and the number of deaths have accumulated globally from 16 362 to 146 088 and in Sweden from 42 to 1 511.

A lot has happened in the interim of these twentyfive days.

We have mobilized resources, learned more about the SARS-CoV-2 virus, an we seem to have passed the worst peak for now (?), and there’s been huge economic stimulus invested (trillions and trillions of dollars) trying to keep society and as many patients as possible from sinking.

The pandemic is far from over and it will have major repercussions for years to come.

But these daily posts have now served their purpose for me as the scope and the pathology of the COVID-19 pandemic is clearer than it was twenty five days ago. I will still keep updating CTSOP regularly, but not daily, and not always with COVID-19 specific posts – the original aim remains to keep adding resources, links and thoughts relating to emergency medicine (both in English and Swedish, and sometimes in Swenglish as they say).

Finally a summary of the 25 posts and some final thoughts on the microembolism theory presented at day 18.

25 Day Summary:

25th March — Are all Systems Go? – A post on preparations before the storm and the mentality of having situational awareness of your resources by checking and rechecking your systems capacity at every shift.
26th March — Predicting the Critical. – A post about temporal changes in laboratory markers from illness onset in patients hospitalized with COVID-19.
27th March — Treatment Alternativess. – A brief mentioning of a small study where hydroxychloroquine (Plaquenil) combined with the antibiotic Azithromycin was used to treat COVID-19 patients. During this time the hospitals in Stockholm had started to administer Chloroquine to certain COVID-19 patients, something that is no longer done due the lack of effectiveness and to side-effects such as long QT-time.
28th March — Exponential Growth. – A look at visualizing the spread and trends of COVID-19 with help of logarithmic scales.
29th March — 7 Clinical Observations. – My observations of COVID-19 symptoms and diagnostics from the daily clinical work at the ER.
30th March — Timeline. – An attempt to map out some of the key events of the pandemic.
31st March — ARDS. – Looking at the age groups and distribution of patients developing severe ARDS and needing intensive care.
1st April — Damage Control. – Discussing the ethics of prioritizing patients in light of extraordinary circumstances when resources might become completely overwhelmed (thankfully it never got as bad as we expected (yet?) in Sweden, thanks in large part due to mobilization of resources, and also – perhaps – social distancing policies).
2nd April — The Curve. – On death tolls rising around the globe and NY becoming the new urban epicenter of the SARS-CoV-2 virus.
3rd April — NOT a Black Swan. – How a virus pandemic was predictable, and how global societies have failed to be prepared despite previous warnings from experts.
4th April — Amat Victoria Curam. – Thoughts on the previous theme, but with a focus on Sweden and the last decades extreme political dismantling of the number of critical care beds and hospital beds in general (compared to other developed countries), leaving us with no margins, no buffer, for when shit hits the fan.
5th April — Another Night Shift. – A short post due to a crazy week with 6 nights at the hospital, culminating with the worst weekend we have ever seen in our ER.
6th April — War-like Scenes in the ER. – As we had our toughest days in the ER with ambulance after ambulance calling in with critically ill patients an article was published at the same time describing similar scenes in the ER of a hospital in NY.
7th April — Work Eat Sleep — Repeat. – On the importance of routines in the midst of the storm.
8th April — POCUS. – On Point of Care Ultrasound and COVID-19.
9th April — STEMI. – Where are all the STEMI patients during this pandemic?
10th April — Extubation. – More and more patients getting extubated from our ICU, things are a now a bit calmer again compared to the previous weekend, and one model projection on when we will reach peak pandemic.
11th April — Microembolism. – Can Anticoagulants Protect Against Getting Severe/Critical COVID-19 pneumonia/ARDS?
12th April — Diarrhea. – The pathophysiology of some patients presenting with diarrhea as a symptom.
13th April — CT Features. – A retrospective analysis of 120 consecutive patients from Wuhan city and what the typical CT thorax findings are in these patients.
14th April — Phase 2. – Is the worst when it comes to hospital influx and the number of critically ill patients needing intensive care at the same time, behind us in Stockholm/Sweden?
15th April — Phenotype L & H. – Categorizing COVID-19 in two types, and how type L is different from severe ARDS (those with type H) , and that there is different optimal treatments for each.
16th April — Covid 19 Cytokine Storm. – J Infect 2020-04-10 article by Yeet et al, ‘Cytokine Storm in COVID-19 and Treatment‘.
17th April — Aftermath. This pandemic will have lasting effects on society for years to come.
18th April. Microembolism part II, summary of the last 25 posts and the last daily post on this pandemic.

Microembolism & Anticoagulants part II

Finally, some additional thoughts on the microembolism theory presented at day 18. In brief: we have seen a considerable decrease of patients with atrial fibrillation in our wards, maybe due to the fact that they are already on anticoagulants that protects them from severe COVID-19 pneumonia, the SARS-CoV-2 virus probably causes (besides lung-embolisms) microembolism in the most critical patients resulting in severe ARDS?

The following report on the cardiopulmonary findings of four autopsies performed on patients within the United States, address thrombotic microangiopathy as a significant finding.

Sharon et al published the report in BMJ 2020-04-06, ‘Pulmonary and Cardiac Pathology in Covid-19: The First Autopsy Series from New Orleans’: *

The dominant process in all cases was consistent with diffuse alveolar damage, with a mild to moderate mononuclear response consisting of notable CD4+ aggregates around thrombosed small vessels, and significant associated hemorrhage. Important additional mechanisms that may have contributed to death in this initial series of autopsies include a thrombotic microangiopathy that was restricted to the lungs. This process may involve activation of megakaryocytes, possibly those native to the lung, with platelet aggregation and platelet-rich clot formation, in addition to fibrin deposition. Small vessel thrombus formation in the lung periphery was in many cases associated with foci of alveolar hemorrhage. In one case, extensive fibrin and early organization was present, with degenerated neutrophils within the alveoli possibly representing neutrophil extracellular traps.

COVID-19 Aftermath – Day 24, Thoughts About The Pandemic

COVID-19 After the Fact

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

Long after the pandemic gets under control the aftermath will still have long lasting effects on everyday life on this planet. No one knows what the new normal will look like but, for better or for worse, things will never be the same again.

At the same time, that goes for any major crisis, things change in the aftermath, and people adapt.

Yet perhaps this one will be different in sheer scale?

Just looking at the employment filing rate in the US since March 15th, there is no equivalent in the last decades that comes close: *

Disregarding the death toll, and just accounting for the devastating effect this pandemic will end up having on people’s life in the aftermath both economically and socially will be worse than anything we seen in recent history.

The trillions of printed money, adding to the, already big, dept of the leading economy of the world will also end up catching up with the world economy in the future even if we manage avoiding a recession now.

We will get through this, but what will it cost in the number of life’s both taken by the virus but also by socioeconomic circumstances?

COVID-19 Phenotype L & H

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

J Infect 2020-04-10 article by Yeet al, ‘Cytokine Storm in COVID-19 and Treatment‘: *

High levels of expression of IL-1B, IFN-γ, IP-10, and monocyte chemoattractant protein 1 (MCP-1) have been detected in patients with COVID-19. These inflammatory cytokines may activate the T-helper type 1 (Th1) cell response(47). Th1 activation is a key event in the activation of specific immunity(48). However, unlike SARS patients, patients with COVID-19 also have elevated levels of Th2 cell-secreted cytokines (such as IL-4 and IL-10), which inhibit the inflammatory response. The serum levels of IL-2R and IL-6 in patients with COVID-19 are positively correlated with the severity of the disease (i.e., critically ill patients > severely ill patients > ordinary patients)(49). Other studies have found that, compared with COVID-19 patients from general wards, patients in the intensive care unit (ICU) display increased serum levels of granulocyte colony-stimulating factor, IP-10, MCP-1, macrophage inflammatory protein-1A, and TNF-α. The above studies suggest that the cytokine storm is positively correlated with disease severity(47)

COVID-19 Phenotypes – Day 22, Thoughts About The Pandemic

April 15, 2020April 15, 2020 / Robert Taeri / Leave a comment

COVID-19 Phenotype L & H

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

What if I told you that perhaps all COVID-19 pneumonia is not best treated as severe ARDS?

Gattinoni et al suggested yesterday, 2020-04-14, in an editorial to Intensive Care Medicine, that there’s a disparity in symptoms and treatment-response in patients with COVID-19, therefore categorizing them in two different phenotypes of COVID-19 pneumonia that can help explain the different ways in which it presents. They describe how type L is different from severe ARDS (those with type H) , and that there is different optimal treatments for each: *

Yet, COVID-19 pneumonia [2], despite falling in most of the circumstances under the Berlin definition of ARDS [3], is a specific disease, whose distinctive features are severe hypoxemia often associated with near normal respiratory system compliance (more than 50% of the 150 patients measured by the authors and further confirmed by several colleagues in Northern Italy). This remarkable combination is almost never seen in severe ARDS. These severely hypoxemic patients despite sharing a single etiology (SARS-CoV-2) may present quite differently from one another: normally breathing (“silent” hypoxemia) or remarkably dyspneic; quite responsive to nitric oxide or not; deeply hypocapnic or normo/hypercapnic; and either responsive to prone position or not. Therefore, the same disease actually presents itself with impressive non-uniformity. (…) Type L, characterized by Low elastance (i.e., high compliance), Low ventilation-to-perfusion ratio, Low lung weight and Low recruitability and Type H, characterized by High elastance, High right-to-left shunt, High lung weight and High recruitability. *

The best way to differentiate between type L and type H patients is, according to the authors, by CT scan where type L patients have only ground-glass opacities primarily located subpleurally and along the lung fissures while typ H patients CT scans shows a ‘remarkable increase in lung weight (> 1.5 kg), on the order of magnitude of severe ARDS.’

They also suggest that the relationship between type L & H is dynamic and can change over time, as a patient presenting with type L at admission kan transition into type H over a couple of days:

Image: from Gattinoni et al, “COVID-19 pneumonia: different respiratory treatments for different phenotypes?” editorial published in Intensive Care Medicine, 2020-04-14. *

Nota bene: Gattinoni et al generally advise against non-invasive options (regardless of type) as they argue that they are associated with high failure rates and delayed intubation!

COVID-19 & Phase 2 – Day 21, Thoughts About The Pandemic

April 14, 2020April 14, 2020 / Robert Taeri / Leave a comment

Have we entered into phase 2 of the pandemic?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

So the easter holidays have come and gone, and the now famous epidemiologist Anders Tegnell warned against reading too much into COVID-19 numbers over the weekend, since less data might have been reported due to less personal at the hospitals.

Well it’s tuesday and the holidays are now over, yet, judging by the data from the previous days (since the last bar/day updates tomorrow) the pandemic curve in Sweden doesn’t seem to be accelerating anymore:

peak
Image: daily number of COVID-19 deaths in Sweden, taken from FHM. *

Perhaps it’s too soon to make any inferences just yet?

Or perhaps the worst is behind us?

The worst so far being the previous weekend, April 4th-5th, when I posted the following at day 13 — observing in that post that we were seeing similar war-like scenes as the ER at NY that was published the same weekend.

What was happening in NY was happening in Stockholm.

So, clearly, it’s too soon to make any conclusions, but maybe, just maybe, the worst wave is over?

If so, how bad will the second and third waves be?

And will there be 3rd and 2nd waves?

UPDATE 2020-04-14 at 19:15:

More probably we’re only seeing a temporary fluctuation before exponential growth continues, as previously observed, the logarithmic graph from Aatish’s page illustrates this well: *

As I previously posted at day 4 of this daily journal, logarithmic graphs are better for visualizing exponential trends.

COVID-19 & CT Features– Day 20, Thoughts About The Pandemic

April 13, 2020April 13, 2020 / Robert Taeri / Leave a comment

Can the CT-scan help differentiate which COVID-19 patients get severe pneumonia?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

Eur Radiol 2020-04-11 article by Zhang et al, ‘CT features of SARS-CoV-2 pneumonia according to clinical presentation: a retrospective analysis of 120 consecutive patients from Wuhan city‘: *

Discussion:

In line with other studies [12,13,14,15,16,17,18,19], the predominant patterns of abnormalities on CT for our 120 patients were GGOs with a peripheral distribution and bilateral, multifocal lower lung involvement. Compared with those of common cases, some CT features were more common in severe cases, such as crazy-paving patterns, bronchiectasis, hilar or mediastinal lymph node enlargement, white lung, air bronchogram, and pleural effusion. We also found that severe cases usually presented as consolidation larger than segmental consolidation, and only severe cases showed an overall lobar or diffuse pneumonia distribution pattern, which indicated that the affected area or volume could also be an important determinant for the disease severity of SARS-CoV-2 pneumonia. However, these patterns also often overlap because CT manifestations are dynamic [15, 16], and depend on various factors, such as disease severity, the evolution of the disease course [14, 15, 20], treatment [12], comorbidity, and complications. Usually, as the disease progressed, the range of GGO patches and consolidation increased. Afterwards, condition would improve, GGO and consolidation disappeared, and fibrous stripes (reticulation) may appear [20]. *

So, in other words, while bilateral GGOs [ground-glass opacities] are a common find in COVID-19 patients, those that get critically ill might also show features such as bronchiectasis, hilar/mediastinal node enlargements, white lung, air bronchograms, pleural effusions, and crazy-paving patterns * *.

Crazy-paving patterns look like this:

Images from: thoracic.org – The American Thoracic Society: “Crazy-paving on CT refers to the findings of ground-glass opacities (patchy or diffuse) with thickened interlobular septae and intralobular lines. It gets its name from the similar appearance to a pathway made up of disorganized paving-stones.” *

COVID-19 & Diarrhea – Day 19, Thoughts About The Pandemic

April 12, 2020April 12, 2020 / Robert Taeri / Leave a comment

Why do some patients get gastrointestinal symptoms such as diarrhea?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

Clin Gastroenterol Hepatol 2020-04-08 article by D’Amico et al, ‘Diarrhea during COVID-19 infection: pathogenesis, epidemiology, prevention and management‘: *

RESULTS:

Clinical studies show an incidence rate of diarrhea ranging from 2% to 50% of cases. It may precede or trail respiratory symptoms. A pooled analysis revealed an overall percentage of diarrhea onset of 10.4%. SARS-CoV uses the the angiotensin-converting enzyme 2 (ACE2) and the serine protease TMPRSS2 for S protein priming. ACE2 and TMPRSS2 are not only expressed in lung, but also in the small intestinal epithelia. ACE2 is expressed furthermore in the upper esophagus, liver, and colon. SARS-CoV-2 binding affinity to ACE2 is significantly higher (10-20 times) compared with SARS-CoV. Several reports indicate viral RNA shedding in stool detectable longer time period than in nasopharyngeal swabs. Current treatment is supportive, but several options appear promising and are the subject of investigation.

So, in other words, we have ACE2 receptors in our guts too, therefor diarrhea in some patients.

Looks like this:

COVID-19 & Micro Embolism – Day 18, Thoughts About The Pandemic

April 11, 2020April 11, 2020 / Robert Taeri / Leave a comment

Can Anticoagulants Protect Against Getting Severe/Critical COVID-19 Pneumonia?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

What we are not seeing at our ward (AVA) is any COVID-19 patients with atrial fibrillation. Usually at least half of our patient monitors are filled with irregular rhythms.

Now there is not a single one (at least not who is also positive with COVID-19, which most patients at the ward are).

These patients all have perfectly regular sinus rhythms.

Which makes us ask ourselves a similar question as the one posted two days ago regarding STEMIs: WHERE ARE ALL THE PATIENTS WITH ATRIAL FIBRILLATION?

One theory is: what if anticoagulants protect against the complications associated with a COVID-19 infection?

What if it all fits?

The fact that SARS-CoV-2 seems to cause a cytokine storm (with IL-6 being activated & elevated among other cytokines), and the elevation of D-Dimer, and the fact that these patients simply seem more prone to get embolisms.

Add to that the fact that the patients in the high risk group also seem to have, already, elevated risk for thromboembolism with risk factors such as: smoking, hypertension, obesity, and age.

What if all the pulmonary complications we are witnessing in the hospital are due mostly to microembolism in the lungs?

What if those already on anticoagulants are protected and that’s why we are not seeing patients with atrial fibrillation being admitted to the same extent as we have previously?

What if that, to some extent, also explains the decline in STEMI patients as many of the patients seeking for chest pain might already be on anticoagulants if they had STEMI previously?

Many questions, a theory that seems to fit, but research is needed to get us from guess work to facts.

Until then, since 9th of April we have new guidelines regarding treatment with anticoagulants where basically anyone positive with SARS-CoV-2 with thrombocyte levels that are adequate are administered LMWH from day one.

The patients who are in need of high levels of oxygen or NIV (non-invasive ventilator) or intensive care are administered double the standard prophylactic dose.

It all seems to fit (however, beware of the high risk of confirmation bias!) – have we finally made a breakthrough regarding the best treatment regimen?

Lets see if the data & research, going ahead, also confirms our theory.

Extubation – Day 17, Thoughts About The Pandemic

April 10, 2020April 10, 2020 / Robert Taeri / Leave a comment

The Calm Before the Storm?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

These last days we’ve seen an unsettling calm compared to the previous weekend.

Less ambulances and less patient in-flow in our ICUs, and as many of the previous patients admitted at the ICU are now being extubated and moved to other wards there is, once again, some margin in the system.

Now there is, once again, room to breathe.

Suddenly we find ourselves over-staffed and (well?) prepared for yet another storm.

The question that springs to mind is: has the tide shifted?

Or is this just a normal fluctuation in the pandemic? The curve might still be trending upwards, but day to day, or even week to week, there will be big differences in the rate of incoming critically ill COVID-19 patients to the hospital.

Looking at one model of Sweden, the peak resource use is (currently since the graph is updated continuously as new data is admitted to the model) reached about 25th of April: *

Also, worth noting, the numbers in the model are not updated. There’s been a considerable amount of mobilization of, among other resources, ICU beds and Stockholm alone has more than tripled the number of available ICU beds. We are not yet at the capacity projected in the model at the peak date (1 169 ICU beds) but we do currently have a lot more than the 79 ICU beds stated in the model as our available resources.

COVID-19 & STEMI – Day 16, Thoughts About The Pandemic

April 9, 2020April 9, 2020 / Robert Taeri / Leave a comment

Where are all the STEMIs?

Daily thoughts & numbers on the COVID-19 pandemic from a M.D. working in the front lines at the Emergency Department in a hospital in Stockholm, Sweden.

After my tuesday night shift I was in our locker room where I met one of our cardiologists that was back from his night shift too.

They have seen, as we have in the ER, significantly less STEMIs during their shifts since the COVID-19 pandemic, so the question we discussed was: where are all the STEMIs?

Apparently what is happening in Stockholm, like most COVID-19 phenomenon, also seems to be happening elsewhere:

From Milan to Madrid to Massachusetts, everyone is asking: as the COVID-19 pandemic drags on, where have all the STEMIs gone? In the Lombardy region of Italy, said Bernhard Reimers, MD (Humanitas Research Hospital, Milan), STEMI cases are down by an estimated 70%. “If symptoms are not too bad, they don’t call the ambulance because they are afraid to go into hospital,” Reimers speculated. *

What’s happening in Stockholm is happening in Lombardy is happening in Washington is happening in Liverpool:

The stories are eerily similar around the globe. At George Washington University Hospital in Washington, DC, Jonathan Reiner, MD, estimated they’ve had just two or three STEMI cases in the last 3 weeks; they usually see three a week, with a yearly volume of 120-150 cases. This has been coupled with a “dramatic decrease” in ACS admissions, he added. At the Liverpool Heart and Chest Hospital in England, Rod Stables, MD, characterized his hospital as experiencing the “calm before the storm.” Yet during the night spent on call before speaking with TCTMD, he did three cases between 5 and 10 PM, then not a single call all night. “That’s unheard of in our place,” he said. Even lower are the hospital-to-hospital urgent referrals for non-STEMI. “We are really feeling the absence of cases there,” he said. *

Nobody knows why STEMIs are so absent in our hospitals during this pandemic. Speculation range from patients not seeking medical attention when they have chest pain to less stressors (unlikely) to doctors missing the diagnosis due to the focus and overwhelm of the COVID-19 patients (and decreased contact/diagnosis by health care personal to save on protective material on the patients in the hospital).
