Tubulin and antibodies

This is very science dense because I wrote it for a group of physicians. I keep thinking that physicians are scientists and full of insatiable curiosity but my own experience with to date 25 specialists since 2012 would say that many are not curious at all. This continues to surprise and sadden me.

______________________________

All science starts with theories. Mothers of children with PANS/PANDAS reactions had to fight to get the medical community to believe that their children had changed after an infection and that symptoms of Obsessive Compulsive disorder and all the other symptoms were new and unexpected and severe. This is a discussion of tubulin and how antibodies work, theorizing based on my own adult experience of PANS. I was diagnosed by a psychiatrist in 2012. No specialist since has agreed yet no specialist has come up with an “overaching diagnosis” to explain recurrent pneumonia with multiple other confusing symptoms.

The current guidelines for treating PANS/PANDAS are here: https://www.liebertpub.com/doi/full/10.1089/cap.2016.0148. This section discusses four antibodies that are a common thread in PANS/PANDAS patients. Antibodies to dopamine 1 receptors, dopamine 2 receptors, tubulin and lysoganglioside.

Per wikipedia “Tubulin in molecular biology can refer either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily.” Tubulin is essential in cell division and also makes up the proteins that allow movement of cilia, flagella and muscles in the human body. There are six members of the tubulin superfamily, so there are multiple kinds.

Antibodies are complicated. Each person makes different antibodies, and the antibodies can attach to a different part of a protein. For example, there is more than one vaccine for the Covid-19 virus, attaching to different parts of the virus and alerting the body to the presence of an infection. Viruses are too small to see yet have multiple surface sites that can be targets for a vaccine. When a cell or a virus is coated with antibodies, other immune cells get the signal to attack and kill cells. At times the body makes antibodies that attach to healthy cells, and this can cause autoimmune disease.

Antibodies also can act like a key. They can block a receptor or “turn it on”. Blockade is called an antagonist when a pharmaceutical blocks a receptor and “turning it on” is called an agonist. As an example of how an agonist and antagonist work, take the pharmaceutical buprenorphine. Buprenorphine is a dual agonist/antagonist drug. In low doses it works as an agonist at opioid receptors. At high doses it is an antagonist and blocks the receptors. It also has strong receptor affinity. This means that it will replace almost all other opioids at the receptor: oxycodone, hydrocodone, morphine, heroin. The blockage and ceiling dose make it an excellent choice for opioid overuse. Higher doses do not give a high nor cause overdose and when a person is on buprenorphine, other opioids do not displace the buprenorphine and give no effect.

Similarly, a tubulin antibody could be an agonist or an antagonist or both. As an agonist, it would block function. My version of PANS comes with a weird version of chronic fatigue. When I am affected, my fast twitch muscles do not work right and I instantly get short of breath and tachycardic. I suspect that my lung cilia are also affected, because that would explain the recurrent pneumonias. My slow twitch muscles are fine. With this fourth round of pneumonia I needed oxygen for over a year, but with oxygen my slow twitch muscles do fine. We have fast twitch fatiguable muscles, fast twitch non-fatiguable, and slow twitch. With six families of tubulin and multiple subfamilies and every person making different antibodies, it is no wonder that each person’s symptoms are highly variable.

Currently the testing for the four antibodies is experimental. It is not used for diagnosis. When I had pneumonia in 2012 and 2014, the antibodies had not yet been described. There is now a laboratory in New York State that will test for them but insurance will not cover the test, it costs $1000 as of last year, and it is not definitive nor useful yet anyhow.

There are studies going on of antibodies in ME-CFS, fibromyalgia, chronic lyme disease, PANS/PANDAS and Long Covid. Recently antibodies from humans with fibromyalgia were injected into mice. The antibodies caused fibromyalgia symptoms in the mice: https://www.sciencedaily.com/releases/2021/07/210701120703.htm. One of the barriers to diagnosis and treatment of fibromyalgia is that science has not found a marker in common that we can test for. Even the two inflammatory markers that we use (C-reactive protein and Erythrocyte Sedimentaion rate) are negative in fibromyalgia. This doesn’t mean that people do not have pain or that it is not real, it just means we have not found the markers. It may be that the markers are diverse antibodies and there is not a single marker.

The research is fascinating and gives me hope. It boggles the mind, doesn’t it?

Qia and the dark

This story is part of a series about a Balint group for angels. Balint groups are groups for physicians to get together and talk about cases that bother them. This often means facing their own biases and discriminatory feelings. I wrote this in January 2022. The current estimate of Long Covid is 10 to 30% of non hospitalized people. Which is huge and terrifying.

___________________________

“And really, it looks like at least half the population will get Omicron. The question,” says Qia, “is how much Long Haul it causes. If it causes 30-50%, like Delta, we are in serious trouble.”

The angels are silent.

“Do you think it will?”

“I am hoping for under 10%.” says Qia. “But of course I do not know.”

Silence again.

“Why do you go to WORST CASE?” snaps Algernon. His wings rustle.

Qia blinks at him slowly.

She thinks about it. “It is the safest place to start.”

Algernon frowns at her. Another angel slowly nods.

“If I start in the worst case scenario, I can face it. I have to think about it, work through it, plan for it. Then I can back off and hope for one of the less horrific scenarios.”

“You are WEIRD.” says Algernon.

Qia is annoyed. Her wings go bat and blood red.

“Word.” whispers a very young angel.

“WHY?” snaps Qia, “WHY NOT face the worst?”

“Most people never do,” says the moderator.

“What?” says Qia.

“Most people never face the worst. They don’t want to. They are terrified. They are scared. They do things to avoid thinking about it. They skip that step and just go straight to hope.”

Qia glares at her. The moderator smiles and her wings go black as pitch.

“We aren’t PEOPLE. We are ANGELS.” says Qia, nearly snarling.

Algernon laughs. “Yeah, well, some of us do not want to think about the worst either. That is Gawd(esses) job.”

Qia is doubly pissed off to be crying. “No, we have to think too.”

“Qia, I agree, but it is hard.” says the moderator. “That is why you have the job you have. Because you are willing to go straight to the dark.”

Qia has her face in her hands.

The angels surround her, soothing, and start to sing.

Conspiracy is easier than vulnerability and grief

“Our culture faces a flood of conspiracism” says the Atlantic Monthly.

My great Uncle forwards an article that says we are tracking along stages as we did to WWII.

I write back. No, I say, we are tracking towards WWI.

Because of Covid-19.

The problem with the pandemic is vulnerability and grief. It is difficult to be mature enough to accept vulnerability and grief. It is easier to find someone to blame and go after them. We can’t burn a virus, we can’t hang it in effigy, we can’t take it to court and give it the death penalty. Many people are terrified and do not want to feel vulnerable and do not want to grieve. So they fall into conspiracies: it is safer to believe that the pandemic is a lie, that alien lizards have taken over the US Government, that it is the fault of a country making it on purpose, or a race, or a religion. It is easier to believe that nanocomputers are being injected with the vaccine than to think about the number of dead. It is easier not to think about the number of dead, the terrifying randomness, to believe that this only affects people with preexisting conditions, or people who God wants to smite, or people the lizard aliens hate. Or that the whole thing is a lie.

We are mimicing the late 19 teens and early 1920s very well. A world pandemic. We have a war, that is not a world war. This time we have bombs capable of destroying current life on earth. We’d be left with tardigrades and those bacteria who live in the deep trenches in boiling water where the earth’s crust is thin. At least one of my friends thinks this might be a good thing.

We have just reached 8 billion people.

In London, the Black Death had a 50% kill rate in the 1400s. Half the people that got it died. It changed the world. Pandemics change the world. In this pandemic the death rate is about 1% or a little more. However, 10% to 30% of the people with Covid-19 have Long Covid. Today, Johns Hopkins says we are at 635 million people who have gotten Covid-19. 6.6 million or more are dead from it. Then we have between 65 million and 195 million people with Long Covid in the world.

We don’t know how long Long Covid lasts. We don’t know how to cure it. We do not know if we can cure it or if people will get better. We do not know, we do not know, we do not know.

Which is also terrifying. So the conspiracy and someone to hate or some group to hate or someone to fight is safer for many people.

Do not go there. We must grieve. We must help each other. We must face fear and not give in to it. We must not fall into the trap of the charismatic leader who will give us villains, who will lead us into a World War to distract us from our grief.

And from there into a world depression. Remember, the Roaring Twenties end with the worst depression the world has seen so far. Let us not repeat it, let us not beat it.

Peace you and blessings.

Covid-19: Long Haul III

The CDC has guidelines for Long Covid and it can qualify for disability in the United States.

Here: https://www.cdc.gov/coronavirus/2019-ncov/long-term-effects/index.html

And here: “As of July 2021, “long COVID,” also known as post-COVID conditions, can be considered a disability under the Americans with Disabilities Act (ADA). Learn more: Guidance on “Long COVID” as a Disability Under the ADA, Section

Here is the list of “most common” symptoms from the CDC:

General symptoms

  • Tiredness or fatigue that interferes with daily life
  • Symptoms that get worse after physical or mental effort (also known as “post-exertional malaise”)
  • Fever

Respiratory and heart symptoms

  • Difficulty breathing or shortness of breath
  • Cough
  • Chest pain
  • Fast-beating or pounding heart (also known as heart palpitations)

Neurological symptoms

  • Difficulty thinking or concentrating (sometimes referred to as “brain fog”)
  • Headache
  • Sleep problems
  • Dizziness when you stand up (lightheadedness)
  • Pins-and-needles feelings
  • Change in smell or taste
  • Depression or anxiety

Digestive symptoms

  • Diarrhea
  • Stomach pain

Other symptoms

  • Joint or muscle pain
  • Rash
  • Changes in menstrual cycles

There are recommendations for a work up by physicians. Depending on symptoms, this may include labs, ECG, echocardiogram (heart ultrasound), CT scan and other tests.

A friend has just gone through those four tests . They are “normal” except for her heart rate. At rest her heart rate is 70 with a normal oxygen level. Walking, her heart rate jumps to 135. Over 100 is abnormal in this athlete who is NOT exerting heavily.

So WHAT is going on with NORMAL testing? I think this is “Covid-19 Viral Pneumonia”, a complication of Covid-19, just as “Influenza Viral Pneumonia” is a complication of influenza. Ralph Netter MD has an illustration of lungs from a person who died of influenza viral pneumonia: the lungs are swollen and inflamed and bruised. WHY is the testing “normal” then? The swelling is throughout the lungs, so a chest x-ray sees it as all the same density and a CT scan also sees it as all the same density. The lungs may have mildly decreased breath sounds, but the sounds are even throughout the lungs. The useful TEST is a walk test. I have tested patients with “walking pneumonia” in clinic for years: get a resting heart rate and oxygen level. Then have my patient walk up and down the hall three times and sit back down. Watch the heart rate and oxygen level. If the heart rate jumps 30 beats up or is over 100, the person needs to continue rest until the heart rate stays under 100 or jumps less than 30 beats. It is important to observe the heart rate until they recover. Sometimes the oxygen saturation will drop as the heart rate comes down, and some people qualify for oxygen. Steroids do not seem to work for this. The length of time to healing is not totally surprising, because a lobar pneumonia that is visible on chest xray takes 6-8 weeks to fully clear. It is not too amazing that a bad walking pneumonia could also take 6 weeks or more to clear. If the person returns to work too soon, they prolong the lung inflammation and they are at risk for exhaustion and for a secondary pneumonia. The treatment is REST REST REST and support.

Do they need oxygen? Currently oxygen is covered only if the person’s oxygen saturation drops down to 88%. However, I think that oxygen would help recovery and make them less exhausted. With my first walking pneumonia, which was influenza, my walking heart rate was 135 and my resting heart rate was 100. Both were abnormal for me. Neither I nor my physician could figure it out. This was in 2003. I did look in my Netter book: I took one look at the painting of the influenza lungs and shut the book. “Oh.” I thought. “That’s why I can’t breathe.” The image is here, though I wish it were bigger.

It took two months for my heart rate to come down, the lung swelling to improve, and me to return to work. I read the text of Dr. Netter’s image a year later and then I read an entire book about the 1918-1919 influenza. Since then I have walked people who come in complaining of exhaustion after a “cold” or “bad cough”. Viruses can cause this and so can bacteria: mycoplasma pneumonia, chlamydia pneumonia, pneumococcal pneumonia, legionella and strep A. If the fever is gone, the infection has probably resolved, but it still can take days or weeks for the lung tissue to recover.

For Covid-19, I would add a third test: walking with weights. We test cardiac patients by asking if they can carry two bags of groceries up a flight of stairs. That is 3 Mets, a measure of the heart load. We need to measure the lung load as well. If the lung tissue is swollen, the amount of airspace is cut down and can be half normal. The heart attempts to take up the slack. The person may tolerate a heart rate of 135 for a while, but it is like running a marathon. If they are older or have heart disease, this can trigger a heart attack. I would walk the person carrying hand weights, and see the recovery.

Also, brain fog is unsurprising. If your oxygen level is borderline, it is darn hard to think. I write really strange songs when I am hypoxic. I get goofy and feel weird. The fast heart rate also feels like anxiety: I think that the body is trying to tell me to rest.

The definition of Long Covid is symptoms after 30 days. Please see your physician if you are still ill and continue to have symptoms.

Blessings.
