@SigmundChurchill Thank you very much for this post. I really appreciate your informed opinion on the matter. I can appreciate what you see is mostly anecdotal but it helps shape and frame where we are at in this battle. We need more posts like this!! 

I have read that this virus is mutating at an exponential rate and that due to these mutations that there is a possibility of re-infection? What's your thoughts on that? 

Also again on the same line of thinking regarding mutations.....do you think that it can mutate itself into a less deadly version?? 

It's really interesting that time and time again when I read about living a long healthy life, minimizing inflammation is a key component. It seems it's playing a factor here again with the cytokine storm you are mentioning.  

Your post was a great balance of keeping things not too technical. Only had to ask the Mrs. (soon to be veterinarian) a couple terms!

Again thanks for the post Mr. Siglo VI !! :)

Can you speak at all to your experience with those diabetes patients. In particular I'm interested in knowing if you're seeing a difference in type 1 and type 2 and then BMI's particularly in the type 2 patients correlating at all with more severe cases.
Awesome info. Thanks

You’re welcome.  As far as mutation, there are now 3 strains that we know about.  Strain A, strain B, and strain C, which can be traced to different parts of the world.  For example, in Wuhan, the original strain (Strain A) has been overtaken by strain B, while in the USA and Australia, it is still Strain A, and in Europe, it is mostly strain B, with a couple of countries showing strain C to be dominant.

Because it is so contagious, it as more opportunity to mutate.  A mutation in a virus is not like the mutations in, say, natural selection.  Meaning, there is no intelligence to a virus mutation.  It is merely an accident.  It can make the virus less virulent, more virulent, or it can be of equal virulence.

Yes, the inflammation, or cytokine storm is interesting because it is not seeming to happen in children.  And as I said, that is likely because their immune system, which is still accustomed to seeing new viruses, is putting out an appropriate immune response.  This is where ADE (or lack of it in their case) might be playing a role.

We are seeing both, but a lot more Type II diabetics.  That could be because there are a lot more type II diabetics in the population, or it could be because type II diabetics are usually obese compared to type I diabetics.  And obesity definitely plays a role in this disease.  Most (but not all) of the patients that are on ventilators, with no pre-existing conditions, and not elderly, are either obese, morbidly obese, or at the very least, clinically overweight.  And that goes for most of the diabetics too.

Type I diabetics, their islet cells (cells that secrete insulin) were seen as foreign and have been destroyed by their immune system.  The islet cells are dependent on angiotensin converting enzyme 2 (ACE2), to secret insulin.  The virus gets into the cells of our body through the ACE2 receptors, not just in the pancreas, but in the lungs and other organs.  Both, lack of insulin (type I diabetes), and insulin resistance (type II diabetes), lead the body to create more ACE2 receptors.  So that may be the link.

I know you didn't ask me but I'll throw in what I'm seeing in the field. I have ran calls on both types 1 and 2 and have seen a wide range of BMI in both types. My experience has been that the real indicator is overall health. I had a patient at the beginning of this that coded shortly after transport, was in the ICU for the last 3 weeks, placed on dialysis because of kidney failure but is starting to recover slowly. Age, and overall health have been a bigger factor out here anyway. Disclaimer I don't deal with the patient long term but do check on their status everyday, their success rate is my success rate. I'm sure @SigmundChurchill will be able to be more eloquent, I'm just a knuckle dragging hose monkey. Stay safe

This is correct.  The few people that survive this stage of the disease are the ones that are younger and otherwise healthy.  

I would even say, a young person with well controlled hypertension, who gets aerobic exercise every day, has a better chance than an older, sedentary person.  Assuming the hypertensive person wasn’t treating their hypertension with ACE inhibitors.  People on ACE inhibitors for hypertension have upregulated the ACE2 receptors in their body, in order to counteract the ACE inhibition from the drug.

Thanks for sharing your experience and thoughts with us here, Elliot. I appreciated reading this.  Here's hoping you continue to stay well-protected as you help people in dire need.

@SigmundChurchill thank you for sharing your experiences. I imagine it is hard to come to a place like this, where we all escape our daily grind a bit, and dive back into what must be a very draining work day.
 

I can only speak for myself but you have helped me better understand the science and frankly the need to maintain good physical conditioning particularly in times like these. 
 

thanks for taking the time to share your thoughts and synthesizing your research. Incredibly helpful.

Amazing read all the way thru. Looking forward to the day the medical community and scientist can pin this thing down. It's caused way too much loss and heartache. 

To all of our medical staff, doctors, nurses, first responders, etc... God speed. Please stay safe. You're risking your health for the sake of strangers, and there's nothing more noble than that. Thank you all, and thank you to your families for sharing such brilliant individuals with the world.

We could never repay you!

SigmundChurchill makes some very nice points and I applaud him and others like him who are treating the most critical and severe cases of SARS-CoV2 infections while putting themselves in a precarious position. While I agree with some of the high level opinions, there are some technical aspects that are a bit misconstrued specifically with the physiology of how Coronaviruses invade healthy host cells. Coronavirus do attach to the ACE2 receptor sites of human host cells through the mechanism of the S protein "spikes" which attach to ACE2 receptors, at that point, the virus produces an enzyme which deactivates the host cell immune response (MDA5 receptor) essentially "blocking" the alarm system which triggers an immune response, thus  allowing the virus' fusion peptides to attach itself to the host cell encode its RNA into the host cell in order to replicate itself. The use of ACE2 inhibitors to treat Covid-19 infections is dicey since ACE2 inhibitors trigger the production of more cellular ACE2 recpetors which then can cause more viruses to attach to more host cells and increasing replication. The hope for a vaccine is a long shot since most vaccines use live attenuated viruses but as Sigmund pointed out, we create Flu vaxes each year and none of them are even 90% effective (I used to mfg FluVirin at Novartis from 2000-2005 and I NEVER received a flu shot nor will I) Fatalities every flu season are not directly proportional to those not receiving flu vaccine but rather due to age, pre-existing medical conditions and susceptibilty to co-infections such as pneumonia. Creation of vaccines using surface protein antigens are rarely effective (harvesting a virus' surface proteins without the virus itself attached and using this to create an antigenic response in the immune system). I had worked with gp120 and gp41 surface proteins of HIV for a company that tried to create a HIV vaccine back in 2000. In addition I have worked in the manufacture of Hepatitis C and B surface proteins c100, NS5, HCCN-1, HBcore, c200 and several others. Such approaches have been rarely effective. There are currently 11 different strains of CoronaVirus and CoVid-19 is one strain. There have been studies to show slight mutations in all 3 of the SARS-Cov1, MERS-Cov and SARS-Cov-19 however there seems to be no indication of any greater virulence due to these slight mutations. Working in the Biopharma industry for 30+ yrs it is my opinion that viruses will not be shut down by vaccines or biologics but rather thru novel small molecule nucleotide and viral polymerase inhibitors such as Sofosbuvir/Ledaspivir which inhibit viral replication. The use of antivirals like remdesivir to treat Covid-19 post infections is still a long way off to determine efficacy since these were developed by my former client Gilead Sciences for the treatment of Ebola and Hanta virus and use of such antivirals that are virus specific are deemed for "Compassionate Use Only" meaning in order to administer them you have to be out of options. The amazing thing about viruses to me and what led my interest to pursue a career in Microbiology, is their ability to utilize different mechanisms for infection and replication and their ability to mutate in order to achieve this activity not to mention being around for 1000s if not millions of years!

What is needed right now is to provide the global public with FACTUAL Information and by providing FULL transparency into the EXISTING # of CoVid-19 reported cases to determine: TOTAL # of Cases Confirmed vs SUSPECTED (symptoms);  The TOTAL # of cases requiring hospitalization; The TOTAL # of Recoveries post infection or onset of symptoms (in other words, after reporting infection, after 3 weeks, those who are recovered should be added to the list of Recoveries), # of deaths DUE to single infection of CoVid-19 vs. co-infections, Deaths by age groups and Deaths Due to pre-existing conditions. While some of this information may be available it is NOT reported in the mASS media,  To Die FROM a virus is different than to Die WITH a virus and such transparency is needed. Once we have complete transparency with regard to data sets, we can then TRULY determine the seriousness of CoVid-19 as compared to similar infections (i.e.seasonal flu numbers) to determine if this is something MORE OR LESS serious of a RISK to people than the damage done to people from a global economic shut down. Infectious Disease experts, Virologists and Epidemiologists across the world should convene to make an assessment on the criticality of this epidemic in relation to other infections and POLITICS should not be involved with this assessment. From that point We Move On from there. Stay smokey my BOTLs!

Thank you.  

I think the only thing I disagree with here is the bolded part.  This goes against everything the CDC tells us, and I have read numbers and the studies that they use to back up that flu-related illness, hospitalizations and deaths are disproportionately found in patients that have NOT received the vaccine, especially in children. Yes, age, pre-existing conditions, etc are the major factors, and these people would especially benefit from the vaccine.

Thanks for your thoughts, and for what you're doing on the "front lines," Elliot. I can't imagine how awful it must be.

A quick question...have you heard anything about the effects or increase/decrease of mortality on people taking TNF-α inhibitors? I ask because my wife uses Embrel to treat RA, and we've been a little concerned, because she's considered immunocompromised. If overreaction if the immune system is a significant factor in many people dying, I'm wondering now if drugs like these might actually convey an advantage of sorts.

I’m out the door on my way to my shift, but I wanted to quickly answer this before I leave.  I don't know of any studies being done, but my initial thought would be that it might make her slightly more susceptible to catching the virus, while at the same time making it less likely for her to die from it.  There is an article in The Lancet that calls for trials to be done on these drugs to see if they are preventative in causing the deadly ARDS that the virus leads to.  

I have to go, but In the meantime, I will post the Lancet article.  Trials of anti-tumour necrosis factor therapy for COVID-19 are urgently needed

Sigmund. I’m curious if and how your institution is using ECMO to treat your patients. This past weekend I’ve seen our main hospital use it on several patients. Several of these have advanced disease on imaging, and several were not intubated (I am a radiologist). I didn’t get a chance to speak with one of the pulmonary/critical care docs directly this past weekend, but my understanding is they are seeing some success with the very sick patients. 

Thanks
