Rehab after covid more important than ineffective drugs
Debate
We welcome research on the reasons why some people develop long-term symptoms after covid. But rehabilitation is an important factor and to treat with drugs without evidence is to do post-covid patients a disservice, writes among others Katharina Stibrant Sunnerhagen, professor of rehabilitation medicine.

Use ME research to treat long-term illness in covid
We believe that discussions about the causes and treatment of diseases should primarily be conducted in academic journals or one of the health care journals. But we still have to respond to some of the statements made in the debate post about people with long-term symptoms after covid. The term long-covid is misleading as it is usually not an ongoing infection, the National Board of Health and Welfare uses the term post-covid for this condition.
Similar conditions
We share Gottfries and co-authors' view that patients with post-covid can present an image that in many parts is similar to that seen in known fatigue conditions after a virus infection. It is important to use knowledge about these when handling post-covid. At the present stage, it is especially important to highlight the knowledge that exists on how to prevent symptoms after infections from becoming long-lasting. For example, the Dallas bedrest study that shows how harmful bed rest is.
The debate article incorrectly claims that there is research that has shown antibodies against one's own body in patients with post-covid. The study that Gottfries refers to is not done in the post-covid, but in the acute phase of covid.
Missing evidence
It is claimed that ME can be assumed to be an autoimmune disease and that it would be shown that post-covid can be an autoimmune disease. Theoretically, both ME/CFS and post-covid can be autoimmune diseases. But despite decades of research, there is no evidence to support the hypothesis that ME/CFS is an autoimmune disease. When you suffer from an illness, you bring with you your history, personality and any other illnesses. In all conditions, the whole affects how one handles one's illness, and covid is affected by the fear that comes from the pandemic.
To treat with drugs without evidence is to do post-covid patients a disservice.
In the debate article, injections of vitamin B12 and low-dose Naltrexone are highlighted as treatments that could benefit post-covid patients. There are no placebo-controlled studies of Naltrexone and the only placebo-controlled study of B12 injections shows that this has no effect on ME/CFS. According to IVO [the Health and Social Care Inspectorate], treatment with B12 injections is “not compatible with good care” in the critical report that the authority submitted in 2015 after its review of healthcare at Gottfries clinic. To treat with drugs without evidence is to do post-covid patients a disservice.
We welcome the Swedish Research Council's investment in research into the causes of some people developing long-term symptoms after covid. The patients who are tormented by post-covid, we hope to get help from a biopsychosocial holistic view. Early rehabilitation is an important factor in preventing long-term illness.
