“8 It has been, indeed, recently recognized that triggers other than heparin can cause a prothrombotic disorder with clinical and laboratory features that strongly resemble HIT. These include certain highly sulfated and highly negatively charged oligosaccharides, such as pentosan polysulfate, hypersulfated chondroitin sulfate and related moleculEs”
The only evidence they have is with hypersulfated chondroitin because some heparin in 2009 was found to have sulfated chondroitin and caused VITT reactions.
We don’t know how chondroitin without being sulfated would cause this. I would stop those glucosamine chondroitin supplements in the pandemic.
“Researchers are beginning to understand how the human immune system contributes to the varied responses to COVID-19. Autoantibodies—immune system proteins that mistakenly target the body’s own tissues—may underlie some of this variation. Autoantibodies are found in a wide range of autoimmune diseases, such as lupus and rheumatoid arthritis. Many people with low levels of autoantibodies in their blood have no obvious symptoms.
A recent study found that autoantibodies that existed before infection with SARS-CoV-2 may account for 20% or more of serious or fatal COVID-19 cases. Scientists have wondered if infection with SARS-CoV-2 could also result in the production of autoantibodies in people who didn’t have them before they got sick.”
Annnddd Covid infection reaction arthritis. Because the autoantibodies attack the chondroitin in the joints.

They also use hydroxychloroquine to treat autoimmune diseases.
