I've listened to this now. Jonas Bergquist did an excellent job!
(Bad PEM, sorry for all the mistakes.)
He said that there are imaging techniques (such as MRI) that show anatomical changes in the brain, and more selective imaging techniques that indicate inflammation in the brain. His team's research focus is studying the cerebrospinal fluid, which is produced in the middle of the brain and flows down through the brain and along the spinal canal. They are measuring biomarkers in the spinal fluid, and they show neuroinflammation, low-grade inflammation that can arise in the brain after infections like this.
Which means that they are starting to understand what is happening in the brain. It can be a part of the explaination for why some people suffer long-term consequences and what causes the disease.
He says that this is not a new phenomenon. There are texts written more than 100 years ago about various virus outbreaks, where patients have suffered long-term consequences.
You are a ME researcher too, are you surprised by these findings? No, not surprised but happy that things have moved forward this much. There are similarities with ME, which in some cases are caused by EBV infection. There are similarities in both blood and spinal fluid. Both diseases can maybe teach us something about the other disease.
What are the differences between ME and post covid? The infection that triggered them. But the symptoms are very similar. It's maybe a little too soon to say that they are the same, but there are big similarities. And they don't just affect the brain, but many organs in the body. There is a list with more than 200 symptoms than can arise after an infection like this.
Some doctors do not agree that this is a real diagnosis? It's not strange that there has been some skepticism. Before you understand something it's difficult to pinpoint it, and that includes treatment options too. You might be a bit unsure and then maybe also a bit careful to say that "this is a disease" or a syndrome, and so on. But he feels that the tone of the conversation has changed for the better now. We are starting to understand how many people are affected and how long-term and severe the consequences can be for some individuals.
Are there biomarkers in the blood too? Can you see them through a blood test? Depending on what organs are affected, it's more or less easy to see also in the blood. New studies have been published very recently where they can see that inflammation markers (the kind that control our immune system) change, and contrary to what one might have guessed some are lowered rather than increased. They are being pushed down as part of a non-functioning immune system.
Do we know how many people in Sweden have post covid? Very unreliable numbers. Globally there might be around 700-800 million people affected by covid infection. If 10% of them suffer consequences that last for more than 6 months, and if maybe 1% of them will suffer more long-term or chronic issues, then it means an absolutely massive group of patients.
What about treatments? There are symptom relieving treatments, depending on what your worst symptoms are. What symptoms are they, usually? Brain fog, neurocognitive issues, lung damage, GI issues, cardiovascular regulation problems. You can get some pharmacological support. There is still no cure, but interesting studies for example about drugs that dissolve micro clots that are impeding the bloodflow in the blood vessels, which might be a possible treatment option. Studies about antivirals show that if you can push down inactive virus particles (that exist in a resting state in our nerves, for examples), if you can decrease their activity it can partially lessen the inflammation too.
He says it's too early to tell what the solution will be. He thinks it probably won't be one solution for everyone, but rather a combination and a custom solution for each individual.
The presenter asks him how far away the solution might be? He doesn't answer, but starts talking about the good news from earlier this week, the government commissioning the National Board of Health and Welfare and the SBU etc.
So, the skepticism has been left behind? He hopes so. "There is much more we need to understand, but I believe that we need to do that with an open mind."
