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?

Winter travel

My daughter and I travel again this winter. We know it’s a crapshoot with the combination of Covid-19, influenza, RSV and weather. She flew from Denver to Seattle. I tested positive for Covid-19 two days before she arrived. Change of plans! A friend of hers picked her up and she stayed with them until I had finished the first five days of isolation. Then she came to my house and we both masked. I ate upstairs and she ate in the daylight basement.

We flew from Seattle a few days before Christmas. We were lucky enough to fly, since the plane the day before was cancelled and on the day after. We had a direct flight Seattle to Dulles. We had a lovely Christmas with my son and daughter-in-law.

We also got to visit with 4 over 80 year old family members once I tested negative for 48 hours. My two aunts and an uncle on my father’s side and a grandmother on their father’s side. I am so happy to have seen all of these elders! Not olders, they are not old until at least 90 and that may move back too!

PANS/PANDAS and diet

I have been thinking about PANS and diet.

When I am sick with pneumonia, I have to keep my carbohydrate intake as low as possible, or I get much much worse. I am attributing this to the lysoganglioside antibody. I have been puzzling about the lysogangilosides because a conference last year says that in some children with PANS/PANDAS, the antibodies cross the blood brain barrier and then macrophages appear to be killing ganglion brain cells. They described a truly awful case. I completely understand children refusing to eat or only eating one or two things when they are having a flare. And everyone may have different food issues because we all make different antibodies. This makes it darned tricky to sort out.

But back to ganglion cells. These are the β€œnerve” cells. They make up the brain but there are also nerve cells all over the body. And more recently we have started calling the gut, the digestive system, as second β€œbrain”. This is because the gut turns out to have tons of ganglion cells.

So, my lysoganglioside antibodies do not appear to attack my brain. But something attacks my gut. It could be any or all of the antibodies, actually. Ganglion cells in the gut would have receptors for dopamine, the gut has smooth muscle that is powered by tubulin and my understanding of lysogangliosides is that they clean up dead or damaged ganglion cells and should not bother healthy ones. Studies of patients with lyme disease are showing the same four antibodies with a rising baseline for people who have more infections, so my guess is that my baseline has risen enough that I do not tolerate gluten. I may try it again, because my good news is that my muscles feel normal again. No more tubulin blocking antibodies, so I have fast twitch muscles again. They are weak but functional. I am starting to exercise them. Hoorah! If I am super lucky, whichever antibody screws up gluten for me has also dropped, but it may not have. The antibodies do not all do the same thing at the same time. This flare started for me when I had my influenza vaccine and then 5 days later, my fourth Covid-19 vaccine. The shots SHOULD get an antibody response but it was annoying to have the muscle dysfunction again. I managed to avoid getting pneumonia, so the response is shortened, about two months. I had very little of the dopamine 1 and 2 effects, so it was a relatively mild effect. The annoying bit was that I was improving in exercise at pulmonary rehab and the vaccines knocked me back down.

When I have pneumonia, eating carbohydrates makes my breathing worse. That’s weird. Well, not really. This fourth go around I realized that I could mitigate the effect of rising blood sugar as I improved by drinking bicarb with each meal. Sodium bicarbonate, baking soda in water. Why did that help?

Bicarbonate is a base. If it helped the symptoms, then it was balancing out an acid. Rising blood sugar was making me acidotic. When we are acidotic, our bodies will try to increase bicarbonate by speeding our breathing. If I have pneumonia and am hypoxic anyhow, then additional pressure on breathing is definitely not a good thing. So adding a glass of water with a teaspoon of baking soda reduced the acidosis. Then food did not affect my breathing.

Would this help all children with a pandas flare? Again, everyone has different antibodies, so the answer is probably NO. I think it is enormously important to listen to children with a PANDAS/PANS flare and give them an assortment of simple foods to choose from. No pressure for a balanced diet at the height of a flare, because some food or food group may make them feel terribly ill and actually may affect their acid/base balance and MAKE them more ill. I would offer something mostly fat: avocado or bacon or a high fat salami or cheese. Some steamed or raw vegetables, ranging from the high carbohydrate to low. Peas are high, kale is low. No sauces or dressing. Some protein sources, chicken breast or meat or beans. A grain or grain source. Offer fruit but do not push. Let the child figure out what they can eat and roll with it. Try to find more things in that food group. Remember that the main food groups are fats, proteins and carbohydrates. There are a bunch of different carbohydrates, which are sugars. Glucose, fructose (in fruit and corn syrup), lactose (in dairy), maltose, dextrose and others. I would avoid junk food and anything prepared. When I am sick I do fine with lactose, but all of the other carbohydrates make me feel very very ill and mess up my breathing. This is individual and will differ from person to person. If eating makes you feel very very ill, it’s easy to understand why some children stop eating. The obsessive compulsive traits are understandable too: if you suddenly don’t tolerate the foods you love and you do not understand what is happening (and your adults don’t either), you might try to behave in ways to bring back the good old days. Do everything the one right way and maybe things will return to normal. It’s a terrifying illness for children and for parents, but I have hope that my experience will help other people.

Blessings.

Keyboard supervisor

Elwha supervising me at the keyboard.

In high school I took typing for dummies. I was terrible at it and slow. Many women were avoiding typing classes in the late 1970s because they did not want to be secretaries. I wanted to be a writer and knew that I was a terrible typist. I also could not spell my way out of a paper bag. My mother was quite dyslexic and did not care. Once I had to sound out a word at the store from her grocery list: “LETIS”. Oh. Got it. Her letters are wonderful, not only interesting and creative spelling, but also wandering tenses and subjects.

We got our first electronic medical record in the early 2000s. We went from looking up labs on a computer and using a computer for maybe an hour total per day to full on eight hours a day. My shoulders and the nurses’ shoulders all locked up and we all filed for Workman’s Comp. I had to work with physical therapy to get my shoulders to unlock. My nurse pointed out that all problems were treated as “User Problems”. That is, WE were the problem, not the program. I realized that having the doctors who love computers pick out the program, learn about it for a year, and then teach us in two days and go live was a massive mistake. None of us understood it nor did we understand any of the computer lovers’ terminology. We rapidly quit asking questions because we didn’t like being treated as morons. Every person who was not a computer lover figured out their own work arounds. Two years later, the computer lovers tried to get us to standardize what we were doing. It’s not very surprising that we resisted and hated them. We had had to figure it out on our own with no help and we were very cynical and disbelieving that they would now “Make it easier.” Nope, they didn’t.

If I were to do it over again, the team picking the electronic medical records would include a couple of older doctors who hate computers. One of the selling points to the computer lovers was “you can write your own templates”. Our response was “We would rather be boiled in oil.” Three years after we got the system I asked the head computer lover doctor to write me a template. It was generic. Patient is complaining of (a problem) (more than one problem). The (problem) has been present for (a day, two days, a week, a month, a year, too long). The problem is (getting worse, the same, getting better). And so forth. Because we had all sorts of problems that did not have a template. My computer lover doc rolled his eyes, but set it up for me.

I also asked the clinic CFO WHY they didn’t set up typing lessons for the doctors who couldn’t type. I watched one of our group hunt and peck with two fingers. “You want them faster, right? You’ve said we could do the whole note in the room. How can they if they can’t type?”

“We are not giving them typing lessons.”

“Well, I think that’s misguided.” Ok, what I meant was that I thought it was STUPID.

Another selling point was that we could finish the note in the room. It turned out that I could do the note in the room after I had fought with the program for two years. It consistently took me 25 minutes. Then they ramped up the schedule and set us all at 20 minute visits. I started running late all the time. I told the front desk, “I’ve been told I should get the note done so I am. And if it takes me 25 minutes, that is what it takes.” Once the hospital kicked me out, I started my own clinic and did 30 minute visits. This did not make me rich but it made me a heck of a lot happier.
