This is what researchers know about long-term covid right now
(Audio, 20 minutes)
More than 11,000 people have been diagnosed with post-covid after they sought specialist care in Sweden since the start of the pandemic. Lisa Norén is the first trial patient to test a covid medicine against post-covid.
Research is currently underway in Sweden, where a couple of hundred patients are receiving active drug treatment. The pill is actually only approved for acute illness with covid, but now it is also being tested against long-term covid.
Those who have palpitations as soon as they get up, after having mild covid19 - there are now different theories about what it is that affects the heart.
Hear about which treatments are underway.
Sympathetic and informative news segment/podcast episode. They are talking about long covid research, an ongoing Swedish Paxlovid study among other things. 124 participants have been recruited so far, they need 100 more. Results are expected this autumn. It's half-blinded, they have controls for Paxlovid, but everybody is getting Ritonavir. Primary outcome is a quality of life questionnaire, they need to improve "10 units" in order for it to be considered effective.
Dr Lisa Norén from the Swedish Covid Association, who is also a participant in the study, describes getting PEM symptoms (without mentioning PEM) after doing the 6-minutes walking test.
Judith Bruchfeld and Artur Fedorowski are interviewed too.
Fedorowski talks a little bit about POTS and they mention a few hypoteses of what might be causing POTS in pwLC:
- inflammation in the autonomic nervous system or the peripheral nervous system, which causes the blood vessels to lose their tightness
- anti-bodies are blocking receptors in the heart and the blood vessels from reading signalling substances correctly
- the vagus nerve might be affected, there might be a brain inflammation/in the central nervous system, which sends incorrect signals to the heart and the blood vessels
Fedorowski briefly mentions potentially treating this by trying to calm the immune system down.
There's also a short comment from the National Board of Health and Welfare, who are currently working on a guideline for post covid "and other post-infectious conditions" which they believe will increase the knowledge about these diagnoses among healthcare professionals in primary care. Expected publication is middle of August 2024. They also stated, in their written comment to the journalist, that it's "difficult to say whether the current knowledge about long covid is sufficient or not"... Norén disagrees, says it's clearly insufficient.
They also mention a guesstimate based on international data, 1 in 30 people or 3-5% of the population might be suffering from long covid presently. Which would add up to 300 000-500 000 persons in Sweden. The official number of people who have gotten specialist care for long covid in Sweden is 11 500, while 30 000 have received the diagnosis long covid in primary care. This would mean that 90% of pwLC in Sweden are undiagnosed and have not gotten any medical care..
Bruchfeld also emphasises that in order to be able to do proper research on this group of patients, there has to be somewhere to gather them (specialist centers), which is not possible when the politicians are closing down specialist clinics and sending people to primary care centers instead.
I believe the study they are talking about is imPROving Quality of LIFe In the Long COVID Patient (PROLIFIC)?

ME is not mentioned, as usual.
(Sorry about my low-quality notes, PEM...)
