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 “nerve” 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 “brain”. 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.

Hammock and filter

I am preparing the cats to travel a bit. I acquired this foldable framed container. The cats are getting used to it. Elwha has decided it makes a nice hammock platform from which to watch me in the kitchen.

We still have smoke from the fires. Seattle is worse than here. The cats are not out for their daily walks until this clears. I am getting lots of knitting and continuing medical education done.

Yesterday I built a Corsi-Rosenthal cube. I bought a box fan and four MERV-13 filters and duct tape. Tape it all into a cube with the filters facing in and the fan facing out and voila! An air filter for my house. Even though I’ve kept the house closed up, the air has been bad for a week. My house is from 1930 and not tight so there is seepage.

Here are the instructions for the cube: https://encycla.com/Corsi-Rosenthal_Cube.

Long Covid and fatigue

Sometimes medical articles are SO IRRITATING! Like this:

Symptomatic Long COVID May Be Tied To Decreased Exercise Capacity On Cardiopulmonary Exercise Testing Up To Three Months After Initial SARS-COV-2 Infection

Healio (10/18, Buzby) reports a 38-study systematic review and meta-analysis “suggested with low confidence that symptomatic long COVID was associated with decreased exercise capacity on cardiopulmonary exercise testing up to 3 months after initial SARS-COV-2 infection.” According to the findings published in JAMA Network Open, “underlying mechanisms may include but are not limited to deconditioning, peripheral mechanisms, hyperventilation, chronotropic incompetence, preload failure and autonomic and endothelial dysfunction.”

Wouldn’t it be nice if they believed the patients?

Let’s break this down. What does it all mean? Ok, the “low confidence” irritates me because it implies that the physicians can’t believe the patients who say “hey, I am short of breath and have a fast heart rate and get really fatigued if I try to do anything!”

I have had my fourth bout of pneumonia with shortness of breath and tachycardia. This time, since I am older, I had hypoxia bad enough to need oxygen. This is the FIRST TIME that some physicians have actually believed me. They believed the pulse oximeter dropping down to 87% and below, with a heart rate in the 140s, but they did not believe me and some accused me of malingering, for the last 19 years. Can you tell that I am a little tiny bit annoyed? If my eyes shot lasers, there would be some dead local physicians. And I AM a local physician, disbelieved by my supposed peers.

Let us simplify this gobbdygook: “underlying mechanisms may include but are not limited to deconditioning, peripheral mechanisms, hyperventilation, chronotropic incompetence, preload failure and autonomic and endothelial dysfunction.” The way I think of it is that sometimes a pneumonia will cause lung tissue swelling. Ok, think of the air space in your lungs as a large balloon. Now the wall of the balloon swells inwards and suddenly there is half as much air space. Guess how your body takes up the slack? The heart goes faster and you have tachycardia. This is a very simple way to think about it. I have tested patients who complain of bad fatigue after an upper respiratory infection with a very simple walk test. 1. I test them at rest, heart rate and oxygen saturation. 2. I walk them up and down a short hallway three times. 3. I sit them back down, and watch the heart rate and oxygen saturation. I watch until they are back to their seated baseline.

A friend tested recently and his resting heart rate was 62. After walking, his heart rate is in the 90s. H does not have a pulse oximeter, but his oxygen level is probably fine. However, that is a big jump. He has had “a terrible cold” for 8 days. I would bet money that his heart rate normally doesn’t jump that much. He still needs recovery time and rest.

In clinic, I had people who were ok at rest but needed oxygen when they walked. We would get them oxygen. More often, they did not need oxygen, but they were tachycardic. When they walked, their heart rate would jump, over 100. Normal is 60-100 beats per minute. If they jumped 30 beats or jumped over 100, I would forbid them to return to work until their heart rate would stay under 100 when they walked. If they went back to work they would be exhausted, it would slow healing, and they might catch a second bacteria or virus and then they could die.

Patients did not need a pulse oximeter. I would teach them to take their own pulse. The heart rate is the number of beats in 60 seconds. I have trouble feeling my own wrist, so I take mine at my neck. It’s a bit trickier if someone has atrial fibrillation but the pulse oximeters aren’t very good with afib either.

When I have pneumonia, my resting heart rate went to 100 the first time and my walking heart rate was in the 140s. I had influenza and felt terrible. My physician and I were mystified. It was a full two months before my heart rate came down to normal. I was out of shape by then and had to build back up. If I tried to walk around with my heart at 140, I was exhausted very quickly and it also felt terrible. The body does NOT like a continuous fast heart rate and says “LIE DOWN” in a VERY FIRM LOUD VOICE. So, I lay down. Until I recovered. For a while I was not sure if I would recover, but I did. This time it was a year before I could go to part time oxygen.

The fatigue follows the heart rate. Tachycardia is not good for you long term. If the heart is making up for reduced air space in the lungs, it doesn’t make sense to slow the heart rate with drugs. You NEED the heart to make up for the lungs. You need to rest, too!

Blessings and peace you.

Red maple

Our native maples are Big Leaf Maple and Vine Maples. There are Red Maples all over town now and they are exquisite and spectacular. Rain is supposed to start this Friday and since we still have bad air quality from the fires in Eastern Washington, I think we will all be glad for rain.

I took this yesterday at Chetzemoka Park. I went to see if the air was ok to beach walk. It was not ok.

The panoramic photograph shows the smoke obscuring the Seattle area and the hazy sun. It is worse there than here but it is not good here either.

I wonder if the trees have trouble breathing too? I am wearing a N95 mask any time I step outside. The cats don’t want to go out right now. They don’t like the smoke.

For the Ragtag Daily Prompt: exquisite and for Cee’s Flower of the Day.

Red sun

This is a sunrise, not a sunset, two days ago on Marrowstone Island. The air quality was deteriorating and I am mostly staying indoors today. We are at high particulate matter and high fine particulate matter, coming from the fires to the east. The recommendation is to mask outside, keep windows closed, use an air filter and mask outside. Also to not exercise heavily outside.

It looks sunny out now, but the air looks wrong. Dirty. My lungs don’t like it at all, not surprisingly. I hope people are taking care of themselves. Stay in, take it easy, mask. Our air is supposed to improve tomorrow.

Blessings and peace you.

Reblog: Desertification

I don’t want to argue about global warming. Let’s talk about deserts instead. Overgrazing, cutting down all the trees and losing topsoil: we have seen this in the United States, with the dust bowl. We have a lot of people in the world to feed, even after all the deaths from Covid-19. We need to take care of land.

Ok, I am lame, that is embedded, not a reblog. I will have to figure out the difference. Feel free to laugh at me. My problem with technology is that it is NOT intuitive. I was horrible with computers until I realized that they are linear and stupid. That is, they only follow the exact right command and they have very little capacity to guess what I mean. I decided that computers were glorified hammers and very very annoying and that the manuals are usually written by people who speak computer, not English. That made it much easier for me to work with computers.

Anyhow, plant a tree. Blessings and peace you.
